[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1As shown, a rope changing device for an endless rope winch comprises several parts, including a rope reel 1, a drum 2, a bearing housing, a motor housing 3, a hydraulic motor 4, a hydraulic station, and a base 5. The waste steel wire rope recycling device is fixed to a flatbed cart 6 via a base clamp 7. The rope reel 1 and the drum 2 are driven by the hydraulic motor 4. The hydraulic station is fixed to another flatbed cart 6 and connected to the hydraulic motor 4 via a hydraulic hose. The rotation of the rope reel 1 is achieved by controlling the operation.
[0024] The structural diagram of rope reel 1 is shown below. Figure 2 As shown, the rope reel 1 is welded from 50mm angle iron. The outer diameter of the rope reel 1 is 1800mm. A 10mm thick iron plate with a diameter of 500mm is welded to the center of the rope reel 1. Six machining holes with a diameter of φ22mm are machined on the iron plate. The center of the machining holes is distributed on an arc with a diameter of φ264mm.
[0025] The structural diagram of roller 2 is as follows: Figure 3 As shown, roller 2 is made of 10mm iron plate. The outer diameter of roller 2 is φ320mm and the length of roller 2 is 1054mm. Inward flanges 8 are welded on both sides of roller 2. There are 6 machining holes with a diameter of φ22mm on the inward flanges 8.
[0026] The drum 2 is fixed together with the rope reel 1 by bolts. The main purpose of adopting the assembly structure is to facilitate the disassembly of the wire rope on the ground. After the rope reel 1, which has been used to recover the wire rope, is brought to the well, the fixing bolts of the rope reel 1 and the drum 2 are removed, and the drum 2 is pulled out from the wire rope. The wire rope disassembly work is completed. The rope reel 1 and the drum 2 are then reassembled in preparation for the next use of the wire rope recovery device.
[0027] The structural diagram of the bearing housing is as follows: Figure 4 As shown, the main function of the bearing housing is to allow the rope reel 1 to rotate. The bearing housing connected to the hydraulic motor 4 is bearing housing 2 10, and the other bearing housing is bearing housing 1 9. The bearing housing consists of four parts: a pin 11, a bearing housing housing 12, a bearing 13, and a cover 14. The pin 11 has a diameter of φ50mm, and the larger diameter end is welded to the rope reel 1. A groove 15 is machined on the contact surface that mates with the bearing 13. After the bearing 13 is installed, a retaining spring is installed in the groove 15 to limit the movement of the bearing 13.
[0028] The bearing housing 12 is fixed on the base 5 with a fixing hole diameter of φ22mm. The bearing housing 12 has an inner diameter of φ110mm, an outer diameter of φ150mm, and a width of 64mm. The bearing 13 is model 6310. Each bearing 13 housing is equipped with two bearings 13. The bearing 13 has an inner diameter of φ50mm, an outer diameter of φ110mm, and a width of 27mm. The pressure cap 14 is mainly used to restrict the bearings 13. The pressure cap 14 has an outer diameter of φ150mm and a boss diameter of φ110mm. There are four machining holes with a diameter of φ14mm on the pressure cap 14. It is connected to the bearing housing 12 by bolts.
[0029] The structural schematic diagram of motor mount 3 is shown below. Figure 5 As shown, the motor base 3 is welded from a 10mm iron plate. The motor base 3 is 500mm long, 205mm wide, and 470mm high. There are 6 machining holes with a diameter of φ22mm on one side of the motor base 3, which are connected and fixed to the base 5 by bolts. There are 4 machining holes with a diameter of φ18mm on the other side of the motor base 3, which are connected and fixed to the motor by bolts. There is a machining hole with a diameter of φ160mm in the middle part for the insertion of the motor boss.
[0030] like Figure 5 As shown, the overall shape of the motor base 3 is Z-shaped. The structural diagrams of the base 5 and the clamping plate are as follows. Figure 6 , Figure 7 As shown, the base 5 is welded from 100# channel steel. The base 5 is 1900mm long, 1600mm wide, and 918mm high. The base 5 is placed on the flatbed trolley 6, with the clamping plate placed underneath. The base 5 and clamping plate are connected by bolts, fixing the base 5 to the flatbed trolley 6. The base 5 and flatbed trolley 6 are assembled, which is convenient for daily storage of the wire rope recovery device. If the base 5 and flatbed trolley 6 were welded together, it would require occupying one flatbed trolley 6 daily, or the repeated welding would increase the workload. The base 5 and clamping plate have two sets of connection holes to accommodate various types of flatbeds in the well. The width of the 25T flatbed trolley 6 is 1300mm, and the width of the 35T flatbed trolley 6 is 1400mm.
[0031] The base 5 is mainly used to fix the rope reel 1. The bolt holes on the side of the base 5 are used to fix the motor base 3, and the bolt holes at the bottom of the base 5 are used to connect and fix it to the clamping plate, thus fixing the base 5 and the flatbed trolley 6. The bolt holes at the bottom of the base 5 extend beyond the outer edge of the flatbed trolley 6. Two bolt holes are arranged at each of the four corners of the base 5, mainly to accommodate flatbed trolleys 6 of different widths. When fixed to a 25T flatbed trolley 6, the inner bolt hole is used for connection, and when fixed to a 35T flatbed trolley 6, the outer bolt hole is used to ensure that the connecting bolts and the outer edge of the flatbed trolley 6 are properly aligned, preventing excessive distance and movement during operation. The shape and structure of the clamping plate depend on the structure of the bottom of the flatbed trolley 6. Since there are reinforcing ribs at the fixing positions of the wheels at the bottom of the flatbed trolley 6, the clamping plate is designed with a U-shaped structure to ensure that the clamping plate can fit snugly against the bottom of the flatbed trolley 6 at the fixing bolt positions, ensuring fastening strength and meeting usage requirements.
[0032] Hydraulic motor 4 is selected from the auxiliary shaft maneuvering system's pusher motor. This motor is a piston motor with an output shaft diameter of φ50mm and four φ22mm fixing bolt holes. The hydraulic pump station is a continuous rope winch hydraulic station. The oil pump of this hydraulic station is a gear pump, located inside the oil tank. The oil pump and motor are connected via oil pipes. The hydraulic transmission allows for motor speed adjustment via control valves, offering better applicability compared to electric motor and gearbox transmissions.
[0033] The working principle of this utility model:
[0034] Before operation, the new wire rope is suspended from the roof of the endless rope winch near the head roadway using a universal connector. The shuttle car is parked and locked near the head roadway. The clamps on the shuttle car are removed, and the two ends of the wire rope are pulled out. The waste wire rope recycling device is parked near the head roadway. The flatbed car 6 and the railway are locked together using a tensioner. The hydraulic pump station is tested for power connection. Personnel are assigned to connect the new and old wire ropes. The other end of the old rope is fixed to the drum 2 of the waste wire rope recycling device. After everything is ready, one person is assigned to follow the rope end to contact the winch driver, another person is assigned to operate the hydraulic control valve of the waste wire rope recycling device, one endless rope winch driver is assigned, and one dedicated person is assigned to guard the connection point of the new and old wire ropes. During rope replacement, the endless rope winch operator rotates the endless rope winch drum 2, causing the old rope to drive the new rope. The old rope is then retrieved through the wire rope recovery device. The operator adjusts the rotation speed of the rope reel 1 by controlling the hydraulic valve until the wire rope passes through the drive drum 2 and is long enough to connect to the shuttle car. The new wire rope and the shuttle car are then connected together using clamps. After tightening the rope and conducting a no-load test, the new rope replacement is completed, and the old rope retraction is also completed at the same time.
[0035] Benefits brought by this utility model
[0036] (1) Economic benefits:
[0037] Previously, replacing steel wire ropes required 10 people per shift, taking two shifts. The total number of workers needed was:
[0038] 10 × 2 = 20
[0039] Removing the old steel wire rope requires 6 people per shift, and 5 shifts are needed. The total number of workers required is:
[0040] 6 × 5 = 30
[0041] The total labor cost for replacing the wire rope in the past was:
[0042] 20 + 30 = 50
[0043] After adopting the new process, 6 people are needed per shift, requiring one small shift. The number of workers required is:
[0044] 6 × 1 = 6
[0045] The number of laborers saved each time the wire rope is replaced after adopting the new process is:
[0046] 50-6=44
[0047] Based on a labor cost of 300 yuan per person per shift, the annual labor cost savings are as follows:
[0048] 300 × 44 = 13200 yuan
[0049] Based on replacing the wire rope 9 times a year, the annual labor cost savings are as follows:
[0050] 13200×9=118800 yuan=118,800 yuan
[0051] (2) Safety benefits:
[0052] The new endless rope replacement process improves the mechanization of operations, reduces the amount of manual labor, reduces the labor intensity of workers, and avoids the safety hazards of collisions during operation, thus greatly improving safety.
[0053] (3) Other benefits:
[0054] The new rope replacement process improves work efficiency, reduces the time spent on transporting vehicles, and alleviates production pressure. It also avoids laying old wire ropes along the railway line, thus improving the standardization of the work site. Furthermore, the new process allows for the neat stacking of old wire ropes after they are brought to the surface, facilitating their management.
