Domestic shield machines have broken through foreign monopoly and most of them have been localized. Corresponding domestic manufacturers also have substitutes of the supporting water pipe drum. However, according to the actual working conditions of the shield machine, the water pipe drum with pneumatic control cable laying is still from foreign countries. The domestic manufacturers use the hysteresis water pipe drum instead. When the diameter of the water pipe is too large and the coiling length is too long, the coiling torque of the hysteresis water pipe drum is often insufficient. The product size is too large, which may be easily limited by the installation space of shield machine, which restricts the development of products. Effect:The utility model is a winding device with a pneumatic brake, which is an electric winding device which can effectively compress the product size by adjusting the air pressure and adjusting the braking torque. According to the working characteristics of the shield machine, when the winding device retracts the cable, the motor is powered on and drives the reel to drag the water pipe from the ground into the reel. When the winding device conducts cable laying, the motor loses power, and the water pipe is dragged out from the reel to the effective distance by external force. At this time, the air pressure can be adjusted by 0-0.8MPa, and the friction torque of the brake can be adjusted to easily drag the water pipe out. The utility model greatly meets the demand of the shield machine market, can comprehensively replace similar foreign products, and has the advantage that it is cost-effective....

A Manufacturing Method of Automatic Winding and Unwinding Device for Flameproof Cable Drum

Patent: A Manufacturing method of automatic winding and unwinding device for flameproof cable drumTechnical Field: The present invention involves a technology for winding and unwinding cables in coal mine equipment, in particular to an automatic winding and unwinding device for flameproof cable drums.Background Art: With the continuous improvement of mechanization degree of coal mine equipment, large-scale electric traction mobile equipment (such as roadheader, continuous miner, shuttle car, etc.) is more and more widely used in coal mines because of its advantages of energy saving, environmental protection and high integrated control degree. Since the towed cable structure is used, the running speed and maximum running distance of these equipment are severely restricted by the performance of cable drum. Mine cable has high voltage (1140V) and there are flameproof requirements to it, and its overall size and weight are very large. Motor drive and electric control are generally used for the traditional cable automatic winding mechanism, and there is no flameproof mechanism in the lead-in and lead-out position of the cable. However, due to the high air humidity in the coal mine and the existence of explosive gases such as methane, the traditional motor drive and electric control can not be directly applied in the coal mine.Contents:The technical problem to be solved by the invention is to propose an automatic winding and unwinding device for flameproof cable drums aim at the shortcomings of the prior art, which can increase the moving distance of equipment, speed up the moving speed of equipment, reduce the workload of miners and improve the working efficiency of equipment. The technical problem to be solved by the invention is realized by the following technical scheme: an automatic winding and unwinding device for flameproof cable drums, comprising a cable drum hydraulic motor, an oil supply pipe and an oil return pipe of the cable drum hydraulic motor, featuring an overflow control system installed between the oil supply pipe and the oil return pipe. The overflow control system consists of a hydraulic control reversing valve and a one-way valve installed on the oil supply pipe, and the oil inlet side of the one-way valve is provided with a winding control oil circuit and an oil drain pipe connected with the oil return pipe. The winding control oil circuit is provided with a high-pressure relief valve, the oil outlet side of the one-way valve is provided with an unwinding control oil circuit connected with the oil return pipe, the unwinding control oil circuit is provided with a low pressure-relief valve, the winding control oil circuit is connected with the winding control position of the hydraulic control reversing valve, the oil drain pipe and the unwinding control oil circuit are connected with the unwinding control position of the hydraulic control reversing valve, and the oil inlet of the hydraulic control reversing valve is connected with the oil supply pipe at the oil outlet side of the one-way valve. The technical problem to be solved by the invention can be further realized by the following technical scheme: a parking brake circuit is arranged between the oil supply pipe and the oil return pipe in the front of the overflow control system, and a hydraulic control one-way valve is arranged on the parking brake circuit. The technical problem to be solved by the invention can be further realized by the following technical scheme: an adjustable throttle circuit and an overhaul circuit are installed between the oil supply pipe and the oil return pipe at the rear of the overflow control system, the adjustable throttle circuit is provided with a throttle valve that can adjust the oil quantity, and the overhaul circuit is provided with a high-pressure ball valve. When winding the cable, the winding control oil circuit is in working state, hydraulic oil enters the hydraulic motor of the cable drum through the one-way valve, and the hydraulic motor drives the cable drum to rotate by feeding oil forward, thus winding the cable. At this time, the oil supply pressure of the hydraulic motor (i.e., the winding torque) is set by the high-pressure relief valve, and when the set pressure value is exceeded, the high-pressure relief valve will realize the pressure relief of overflow. When unwinding the cable, the cable is pulled out of the drum by the traction of the shuttle car, which makes the hydraulic motor rotate in the reverse direction and work in the mode of hydraulic pump. The pressure of the oil supply pipe at the oil outlet side of the one-way valve rises, which makes the hydraulic control reversing valve move to the unwinding control position. At this time, the pressure oil directly returns to the oil tank through the oil drain pipe, and the high-pressure oil discharged from the hydraulic motor goes to the oil return tank through the unwinding control oil circuit, and the low-pressure relief valve controls the oil return pressure. When the equipment is stationary and in the parking brake state, the hydraulic control one-way valve controlled by the pressure of the parking brake system is opened, and the oil supplied by the oil pump directly returns to the oil tank without passing the control valve block, which can greatly reduce the working load of the pump and the system calorific value. Compared with the prior art, the positive and negative rotation of the hydraulic motor is automatically controlled through the overflow of the high-pressure relief valve and the low-pressure relief valve under the set pressure in this invention, thereby realizing the automatic winding and unwinding of the cable. The cable drum automatic winding and unwinding device can be widely used in various underground electric traction devices in coal mines. By realizing automatic winding and unwinding of cables on flameproof cable drums, automatic pressure relief, buffering and shock absorption, overload protection, and cable full winding and unwinding protection, it can effectively increase the running distance of the devices, improve the running speed of the devices, simplify the operation procedures, reduce the workload of miners, improve the working efficiency of the devices, greatly promote the wide application of large-scale electric traction mobile devices in coal mines, and improve the localization speed, thus it features great economic and social benefits. The hydraulic principle diagram of the present invention is shown in Fig. 1.Detailed description of the invention: An automatic winding and unwinding device for flameproof cable drum, comprising a cable drum hydraulic motor 7, an oil supply pipe 11 and an oil return pipe 1 of the cable drum hydraulic motor 7. The oil supply pipe 11 is connected with a gear pump, the oil return pipe 1 is connected with an oil return tank, an overflow control system 12 is installed between the oil supply pipe 11 and the oil return pipe 1. The overflow control system 12 includes a hydraulic control reversing valve 14 and a one-way valve 13 installed on the oil supply pipe. On the oil inlet side of one-way valve 13, there are winding control oil circuit 2 and oil drain pipe 3 which are connected with the oil return pipe. The winding control oil circuit 2 is provided with a high-pressure relief valve 9, while the oil outlet side of one-way valve 13 is provided with an unwinding control oil circuit 4 which is equipped with a low-pressure relief valve 8. The winding control oil circuit  2 is connected to the winding control position of the hydraulic control reversing valve 14, and the oil drain circuit 3 and the unwinding control oil circuit 4 are connected to the unwinding control position of the hydraulic control reversing valve 14. The oil inlet of the hydraulic control reversing valve 14 is connected with the oil supply pipe on the oil outlet of the one-way valve. A parking brake circuit is designed between the oil supply pipe and the oil return pipe in the front of the overflow control system 12, and a hydraulic control one-way valve 10 is installed on the parking brake circuit. An adjustable throttle circuit and an overhaul circuit are installed between the oil supply pipe and the oil return pipe at the rear of the overflow control system 12. The adjustable throttle circuit is equipped with a throttle valve 5 with adjustable oil quantity and the overhaul circuit is equipped with a high-pressure ball valve 6. Oil is supplied by a gear pump with a flow rate of 21.71L/Min, which is one of the triple pumps, and its main function is to control the automatic winding and unwinding of cables. The working principle is that the positive and negative rotation of the hydraulic motor is automatically controlled through the overflow of the high-pressure relief valve and the low-pressure relief valve under the set pressure in this invention, thereby realizing the automatic winding and unwinding of the cable. The working process is as follows: When the shuttle car runs in the direction of power supply, that is, when the cable is wound up, the hydraulic control reversing valve is in the left winding control position under the action of the reset spring, and the pressure oil output by the gear pump enters the hydraulic motor of the cable drum through the one-way valve, and the hydraulic motor drives the cable drum to rotate by feeding oil in the forward direction, so as to wind up the cable. At this time, the oil supply pressure of the hydraulic motor (i.e., the winding torque) is set by the high-pressure relief valve, and the pressure value is set according to the cable parameters of the shuttle car and the hanging angle of the cable when the equipment is under operation. When the shuttle car runs away from the power supply, that is, when the cable is unwound, the cable is pulled out from the drum under the action of the traction force of the shuttle car, which makes the hydraulic motor rotate reversely and work in the mode of hydraulic pump. The one-way valve is closed, which makes the pressure of the oil inlet controlled by the hydraulic control reversing valve increase, and the valve core is reversed under the action of the reverse control pressure. At this time, the oil discharged from the oil pump directly returns to the oil tank through the reversing valve and the oil drain pipe, and the high-pressure oil discharged from the hydraulic motor returns to the oil tank through the low-pressure relief valve, and only a part of the oil participates in circulation of oil supply of the motor. Set the pressure of the low-pressure relief valve according to the cable parameters (weight and tensile strength, etc.). When the equipment is stationary and in the parking brake state, the hydraulic control one-way valve controlled by the pressure of the parking brake system is opened, and the oil supplied by the gear pump directly returns to the oil tank without passing the overflow control system, which can greatly reduce the working load of the pump and the system calorific value. The throttle valve with adjustable oil quantity can adjust the flow according to different cable types, and at the same time buffer the impact torque of the motor when winding the cable. The high-pressure ball valve opens when the cable drum has fault or is installed for the first time, which can realize the free rotation of the cable drum. The high-pressure overflow condition is when the shuttle car is not moving and the parking brake is not executed, and when the shuttle car is driving in the direction of power supply (i.e. the cable winding state); The low-pressure overflow condition is when the shuttle car runs away from the power supply (i.e. the cable unwinding state); The working condition of the hydraulic control one-way valve is when the equipment is under parking brake; The opening conditions of high-pressure ball valve is when the oil pump motor shuts off and the cable drum needs to rotate freely.Claims:1.

摘要：针对三峡库区大水位差下的岸电电缆收放难的问题，基于滑轮组原理，设计了一套钢丝绳缠绕系统，利用浮箱的浮力驱动传动装置和电缆卷筒运行，在库区水位发生变化时，电缆卷筒可实现对电缆的自动收放，且无需人员值守，绿色安全，为工程的具体设计提供了一种新的可行方案。 1、引言    岸电设施是指船舶在码头停靠期间，由岸上供电系统向船舶提供电力，用以替代船舶燃油发生的设施。随着国内航运的快速发展，船舶排放温室气体量日益增多，岸电设施作为船舶油改电的重要手段，能够降低船舶污染物的排放量，因此得到了快速的发展和应用。    近日来，国内外对于于岸电设施的研究与应用较多，但主要以海港为主，这是因为海港用电需求大，建设难度小，能够取得较好的经济效益；对于水位变化幅度较大的内河区域，面临建设成本高、难度大等问题，如何方便地收放供电电缆，一直没有较好的解决办法。    目前，内河码头的岸电多采用人力拖缆上岸的方式，这种方式效率低、安全隐患大。徐元潮等设计的多级伸缩装置的输缆设备，能够向上提升10m，但不适合水位变化较大的内河区域。2、工程概述    本工程处于三峡库区长江右岸的旧州河河口附近，每个锚泊点由2座系靠船墩组成，可供船舶单艘或者多艘并列停靠。为解决船舶停靠时的供电，拟设备配套的岸电设施，根据《码头船舶岸电设施建设技术规范》（JTS155-2012）要求以及现场调研，船舶受电采用400V/50Hz等级，功率按照400KW设计。受三峡库区调试，锚泊点所在区域水位变化曲线见图1。    锚地区域水位每年6月初到9月底维持在145m，10月初水库开始蓄水，11月初水位升到175m，并维持至翌年12月底，1月初水位开始下降，5月底降落至145m，高水位与低水位落差达30m。此外，由于锚泊点处于库区水域之中，地处偏僻，要求无值守。3、岸电系统总体设计    岸电设施设计的难点在于，在无人值守的条件下如何适应水位的变化，如何准确收放电缆。针对上述要求，结合系靠船墩结构，设计了一套浮箱岸电设施，具体布置见图2。    电缆转接箱从陆域变电站接电，输出至电缆卷筒，电缆卷筒输出给岸电箱，岸电箱置于浮箱上，浮箱置于导向架内，导向架固定于系靠船墩上（见图3）。浮箱可随水位沿导向架上下浮动，通过一套钢丝绳缠绕系统实现电缆的自动收放。4、钢丝绳缠绕系统    钢丝绳缠绕系统主要由滑轮、钢丝绳、联轴板等组成，其原理图见图4。       钢丝绳分为A、B、C、D、E5段，两端分别固定，经绕定滑轮滑轮1、2，以及动滑轮3、4形成滑轮组，动骨轮3和4通过联轴板5相连，固定于浮箱一侧；定滑轮1的转轴与传动装置6的输入轴相连，传动装置6的输出轴与电缆卷筒轴相连，而电缆卷筒上的电缆输出端与岸电箱相连。其中传动装置6实际为一变速器，具有一定的传动比，使得浮箱上下的位移与同时间段内的电缆收放量保持一致。    本系统的原理为：当水面上升时，浮箱随水位沿导向架垂直上升，带动联轴板5向上运动，联轴板5驱使动滑轮4向上运动，整个装置开始运行，动作顺序依次为：浮箱上升→联轴板5上行→动滑轮4顺时针运行→定滑轮2逆时针运行→定滑轮1逆时针运行→传动装置6同向运行→电缆转筒逆时针转动→电缆被卷起收回，从而适应水位的上升，与此同时动滑轮3顺时针运行。    反之，当水位下降时，浮箱随水位沿导向架垂直下降，带动联轴板5向下运动，联轴板5驱使动滑轮3向下运行，整个装置开始运行，动作顺序依次为：浮箱下降→联轴板5下行→动滑轮3逆时针运行→定滑轮1顺时针运行→传动装置6同向运行→电缆转筒顺时针转动→电缆被释放，从而适应水位的下降，与此同时定滑轮2顺时什运行→动滑轮4逆时针运行。    钢丝绳缠绕系统的直接动力源自于浮箱所受的浮力，且理论上浮箱只能上下作直线运行，故方案中设置有专门的导向架，并配合导轨，用以保证浮箱规则运行。    至此，完成了钢丝绳缠绕系统的在岸电收放电缆的逻辑设计，设计中电缆的收缆装置为机械式，通过钢丝绳缠绕系统的作用即可完成输电电缆的收放。该系统能够自适应于不同的水位，且无需人员值守。5、结语    通过对三峡库区锚泊系靠船墩结构和水位的分析，设计了一种浮箱岸电设施，该设施中采用特定的钢丝缠绕系统，利用浮箱浮力驱动其运转，进而带动电缆卷筒工作，从而实现了在不同水位下电缆的准确收放。本系统工作时无需人员值守，绿色安全，为工程的详细设计从理论上提供了一种新的可行方案。 摘自《港口装卸》2020年第6期...
