Description

Technical Field

[0001] This invention relates to the field of subway electromechanical construction technology, specifically to a cable winding and unwinding device and method for subway electromechanical construction. Background Technology

[0002] The laying and winding of cables for subway electromechanical construction is a crucial step in ensuring construction quality and safety. Through proper planning, design, and operation, the safe and efficient use of cables can be guaranteed, providing a strong guarantee for the smooth progress of subway electromechanical construction. Before laying cables, the length, quantity, and type of cables to be used need to be determined according to the construction plan and design. During laying, the cable route needs to conform to the subway route. Because the total amount of cables used in subway construction is relatively large, cable laying and winding devices will be used.

[0003] Traditional cable winding and unwinding devices simply release the coiled cable or wind up the cable to be recycled onto the cable winding roller. However, when laying cables, the cables need to be bent according to the subway route. These bending operations are mostly done manually, which is time-consuming and labor-intensive. In addition, the high rigidity of the cables makes manual bending difficult. Therefore, improvements are needed. Summary of the Invention

[0004] To address the time-consuming and labor-intensive problem of manually bending cables during existing cable laying methods, this invention proposes a cable winding and unwinding device and method for subway electromechanical construction. This invention can perform cable winding and unwinding operations, and achieves cable bending through a vertical drive assembly and a cable laying assembly, while preventing the cable from being pulled back during bending.

[0005] This invention proposes a cable winding and unwinding device for subway electromechanical construction, specifically comprising a base, a winding assembly, two adjusting brackets, two vertical drive assemblies, and two cable laying assemblies. The winding assembly and the two adjusting brackets are arranged parallel to each other on the base. The cable laying assembly is mounted on the adjusting bracket, and the vertical drive assembly is mounted at the lower end of the adjusting bracket, with the vertical drive assembly and the cable laying assembly connected. The cable laying assembly includes two sliding support seats, a limiting rod, a reciprocating screw, a third motor, and a cable laying device. The sliding support seats are slidably mounted on the adjusting bracket, the limiting rod and the reciprocating screw are positioned between the two sliding support seats, and the cable laying device is mounted on the limiting rod and the reciprocating screw. The third motor is mounted on the sliding support seat, and the output end of the third motor is connected to the reciprocating screw. The cable is wound onto the winding assembly and passes through the cable laying device.

[0006] Furthermore, the vertical drive assembly includes a lead screw, two sliding blocks, two transmission push rods, and a second motor. The lead screw is rotatably mounted at the lower end of the adjusting bracket and connected to the output end of the second motor. Two sections of threaded structures with opposite directions are symmetrically arranged on the lead screw. The two sliding blocks are respectively fitted onto one section of the threaded structure. The sliding blocks and the transmission push rods are hinged together, and the other end of the transmission push rods is hinged together with the sliding support seat.

[0007] Furthermore, one of the adjustment brackets is fixedly mounted in the middle of the base, and the other is slidably mounted at one end of the base; the slidably mounted adjustment bracket is provided with a one-way limiting component, which includes two support rods and a limiting seat. The two support rods are arranged parallel to each other in the vertical direction between two sliding support seats; the limiting seat is slidably mounted on the two support rods, and the cable passes through the through hole on the limiting seat.

[0008] Furthermore, a number of limiting closing blocks are arranged circumferentially around the through hole of the limiting seat, and one end of the limiting closing block is hinged to the limiting seat; the cable passes through the circular structure formed by the number of limiting closing blocks, and a friction layer is provided on the side of the limiting closing block facing the cable.

[0009] Furthermore, the cable guide includes a cable guide body, a clamping member, and a limiting and fixing block. The clamping member is provided on the cable guide body through the limiting and fixing block, and several rollers are provided inside the clamping member.

[0010] Furthermore, the winding assembly includes a support frame, a cable roller, and a first motor. The support frame is mounted on a base, and the cable roller is rotatably mounted on the support frame. The first motor is mounted at one end of the support frame, and the output end of the first motor is connected to the cable roller.

[0011] Furthermore, the base is equipped with a hydraulic telescopic rod, the telescopic end of which is connected to the bottom of a slidingly mounted adjustment bracket.

[0012] A cable winding and unwinding method using the aforementioned cable winding and unwinding device for subway electromechanical construction includes the following steps:

[0013] S1. Adjust the height of the cable laying assembly by using the vertical drive assembly, so that the cable on the winding assembly passes through the two cable laying devices and the limit seat to fix the cable; start the third motor to drive the cable laying device, so that the cable laying device follows the cable horizontally to keep the cable laid out in a straight line and avoid bending when laying in a straight line.

[0014] S2. When the cable needs to be bent vertically, the vertical drive component controls the two cable guide components to move up and down, and the two cable guides bend the cable. When the cable needs to be bent horizontally, the two reciprocating screws drive the corresponding cable guides to bend the cable.

[0015] The beneficial effects of the cable winding and unwinding device for subway electromechanical construction described in this invention are as follows:

[0016] (1) The cable winding and unwinding device and cable winding and unwinding method for subway electromechanical construction described in this invention have the advantage of keeping the cable in a straight state when winding and unwinding it by setting up a vertical drive component and an adjustment bracket. The cable is inserted into the clamp and the limiting seat and fixed. The second motor drives the screw to rotate, which causes the sliding block to drive the transmission push rod to move. Then the transmission push rod adjusts the cable laying component, so that the cable laying component limits the cable.

[0017] (2) The cable winding and unwinding device and cable winding and unwinding method for subway electromechanical construction described in this invention have the advantage of conveniently bending the cable through the cooperation of the cable winding assembly and the vertical drive assembly. The second motor is controlled to drive the lead screw to rotate in opposite directions, and the sliding support seat is moved through the transmission push rod, so that the sliding support seat can drive the cable winding device to move up and down, so that the cable winding device can be misaligned up and down, and the cable can be bent up and down. The third motor can also be controlled to drive the reciprocating lead screw to rotate in opposite directions, so that the cable winding device can move in opposite directions to form a horizontal misalignment, and the cable can be bent left and right.

[0018] (3) The cable winding and unwinding device and cable winding and unwinding method for subway electromechanical construction described in this invention have the advantage of preventing the cable from being pulled back when it is bent by setting a one-way limiting component. When the vertical drive component and the cable laying component work together to bend the cable, the cable will rub against the friction layer, thereby pulling the limiting closing block inward to form a reduced trumpet shape to clamp and fix the cable, so as to avoid the cable being pulled back when it is bent and affecting the cable laid at the front end.

Detailed Implementation

[0031] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings:

[0032] Specific implementation method one: See Figures 1-9This embodiment describes a cable winding and unwinding device for subway electromechanical construction. Specifically, it includes a base 1, a winding assembly 3, two adjusting brackets 4, two vertical drive assemblies 5, and two cable laying assemblies 6. The winding assembly 3 and the two adjusting brackets 4 are arranged parallel to each other on the base 1, with the winding assembly 3 positioned on one side of each adjusting bracket 4. The cable laying assembly 6 is mounted on the adjusting bracket 4, and the vertical drive assembly 5 is located at the lower end of the adjusting bracket 4. The vertical drive assembly 5 is connected to the cable laying assembly 6, and its height is adjusted by the vertical drive assembly 5. The cable laying assembly 6 includes two sliding support seats 601, a limiting rod 602, a reciprocating screw 603, a third motor 604, and a cable laying device 605. A slide rail is provided inside the adjusting bracket 4, and... A limit block is provided at the bottom, and the sliding support 601 is slidably mounted on the slide rail inside the adjusting bracket 4; the limit rod 602 and the reciprocating screw 603 are arranged side by side between the two sliding support 601s, and the cable guide 605 is slidably mounted on the limit rod 602 and the reciprocating screw 603. The reciprocating screw 603 drives the cable guide 605 to move, and the cooperation of the limit rod 602 and the reciprocating screw 603 makes the movement of the cable guide 605 more stable; a third motor 604 is provided on one of the two sliding support 601s, and the output end of the third motor 604 is connected to the reciprocating screw 603 to drive the reciprocating screw 603 to rotate; the cable is wound on the winding assembly 3 and passes through the cable guide 605 of the two cable guide assemblies 6.

[0033] The vertical drive assembly 5 includes a lead screw 501, two sliding blocks 502, two transmission push rods 503, and a second motor 504. The lead screw 501 is rotatably mounted on the lower end of the adjusting bracket 4 and connected to the output end of the second motor 504. Two sections of threaded structures with opposite directions of rotation are symmetrically arranged on the lead screw 501. The two sliding blocks 502 are respectively fitted onto one section of the threaded structure. The sliding blocks 502 are hinged to the transmission push rods 503, and the other end of the transmission push rods 503 is hinged to the sliding support 601. When the second motor 504 drives the lead screw 501 to rotate, the two sliding blocks 502 move in opposite directions under the drive of the threaded structures with opposite directions of rotation, pushing the cable assembly 6 up or down via the transmission push rods 503. When the two cable assemblies 6 are at different heights, the cable can be bent vertically.

[0034] One of the two adjusting brackets 4 is fixedly installed in the middle of the base 1, and the other is slidably installed at one end of the base 1. The slidably installed adjusting bracket 4 is provided with a one-way limiting component 7, which includes two support rods 701 and a limiting seat 702. The two support rods 701 are arranged parallel to each other in the vertical direction between two sliding support seats 601. The limiting seat 702 is slidably installed on the two support rods 701, and the cable passes through the circular through hole on the limiting seat 702.

[0035] The limiting seat 702 has several mounting grooves arranged around its circular through hole. A limiting closing block 703 is installed in the mounting groove. One end of the limiting closing block 703 is hinged to the limiting seat 702, allowing the limiting closing block 703 to swing within the mounting groove. The cable passes through the circular structure formed by the limiting closing blocks 703. A friction layer 704 is provided on the side of the limiting closing block 703 facing the cable. After the limiting closing block 703 closes towards the center, it forms a trumpet shape that gradually narrows from the inside out. By setting a one-way limiting component 7, the support rod 701 keeps the limiting seat 702 stable and enables the limiting seat 702 to move vertically synchronously with the cable guide 605. After the cable passes through the limiting seat 702, the limiting seat 702 can move horizontally synchronously with the cable guide 605. When the vertical drive component 5 and the cable guide component 6 work together to bend the cable, the cable may be pulled back. At this time, the cable will rub against the friction layer 704, which will pull the limiting closing block 703 inward to form a reduced trumpet shape to clamp and fix the cable, so as to prevent the cable from being pulled back when bending and affecting the cable laid at the front end.

[0036] The cable guide 605 includes a cable guide body, a clamping member 606, and a limiting and fixing block 608. The clamping member 606 is provided on the cable guide body through the limiting and fixing block 608. Several rollers 607 are provided inside the clamping member 606 to ensure that the cable passes smoothly through the inside of the clamping member 606.

[0037] The winding assembly 3 includes a support frame 2, a cable roller 301, two intercepting blocks 302, and a first motor 303. The support frame 2 is mounted on the base 1. Each end of the cable roller 301 is provided with an intercepting block 302. The cable roller 301 is rotatably mounted on the support frame 2 through the two intercepting blocks 302 to keep it stably unloading the cable. One end of the support frame 2 is provided with the first motor 303, and the output end of the first motor 303 is connected to the cable roller 301.

[0038] The base 1 is equipped with a hydraulic telescopic rod 8. The telescopic end of the hydraulic telescopic rod 8 is connected to the bottom of the sliding adjustment bracket 4. The position of the sliding adjustment bracket 4 on the base 1 can be adjusted to achieve different bending arcs of the cable. It can also leave a distance for leveling the cable when winding, so that the cable roller 301 can wind it up neatly.

[0039] A cable winding and unwinding method using the aforementioned cable winding and unwinding device for subway electromechanical construction includes the following steps:

[0040] S1. Adjust the height of the cable laying assembly 6 by using the vertical drive assembly 5. Start the second motor 504 to drive the lead screw 501 to rotate, causing the sliding block 502 to move and then push the cable laying assembly 6 to the horizontal position of the cable head on the cable roller 301 through the transmission push rod 503. Then loosen the bolts on the clamping member 606 and simultaneously loosen the limiting fixing block 608 to separate the clamping member 606. Then pass the cable wound on the cable roller 301 through the middle of the pair of clamping members 606 and through the middle of the limiting seat 702. Tighten the bolts and the limiting fixing block 608 to close the clamping member 606. Then start the first motor 303 to drive the cable roller 301 to rotate, so that the cable is released from the cable laying device 605 and the limiting seat 702. At the same time, start the third motor 604 to drive the cable laying device 605, so that the cable laying device 605 moves horizontally with the cable to keep the cable released in a straight line and avoid bending when laying in a straight line.

[0041] S2. After laying the cable to the location where bending is required, if an upward or downward bending radius is needed, the second motor 504 is controlled to drive the lead screw 501 to rotate in the opposite direction, so that the cable laying assembly 6 moves upward and downward under the pull of the transmission push rod 503, and the cable laying device 605 bends the cable. Similarly, when a horizontal bending is needed, the third motor 604 is controlled to drive the reciprocating lead screw 603 to rotate in the opposite direction, so that the reciprocating lead screw 603 drives the cable laying device 605 to move in the opposite direction, thereby bending the cable in the required direction, saving the step of manual bending.

[0042] The specific working process of the cable winding and unwinding device for subway electromechanical construction described in this invention is as follows:

[0043] By activating the hydraulic telescopic rod 8 to move the adjusting bracket 4, space is created between the cable laying assemblies 6. When the winding assembly 3 releases the cable, the vertical drive assembly 5 and the cable laying assembly 6 work together to limit the cable. When it is necessary to bend the cable, the position of the cable laying assembly 6 can be adjusted to bend the cable appropriately. When the cable is bent, the one-way limiting assembly 7 can clamp the cable to prevent the laid cable from being pulled when bending, thus affecting the overall planned length.

[0044] The reciprocating screw 603 is driven to rotate by the third motor 604, which in turn drives the cable guide 605 to move horizontally back and forth, enabling the cable to bend left and right. The design of the clamping part 606 and the limiting fixing block 608 can easily clamp the cable in the middle, and can rotate with the bending direction when bending the cable left and right to avoid damaging the cable. The roller 607 set in the clamping part 606 can prevent the cable guide 605 from rubbing and jamming the cable when releasing the cable.

[0045] By controlling the second motor 504 to drive the lead screw 501 to move in different directions, the transmission push rod 503 pushes the sliding support 601 to move, so as to facilitate the adjustment of the vertical position of the cable assembly 6. When the second motor 504 drives the lead screw 501 to rotate in opposite directions, the lead screw 501 drives the sliding block 502 to move towards the center and both sides, and then pushes the sliding support 601 to move through the transmission push rod 503. This allows the sliding support 601 to drive the cable arranger 605 to move up and down, so that the cable arranger 605 can be staggered up and down to bend the cable. When the third motor 604 drives the sliding support 601 to rotate in opposite directions, it drives the cable arranger 605 to move in opposite directions, so that the cable arrangers 605 are staggered horizontally to bend the cable left and right. When winding up the old cable, the two cable arrangers 605 are kept in corresponding positions to straighten the bent old cable for easy winding. When the vertical drive assembly 5 and the cable assembly 6 work together to bend the cable, the cable may be pulled back. At this time, the cable will rub against the friction layer 704, which will pull the limit closing block 703 inward to form a reduced trumpet shape to clamp and fix the cable, so as to prevent the cable from being pulled back when bending and affecting the cable laid at the front end.

[0046] In summary, the cable winding and unwinding device and method for subway electromechanical construction described in this invention, through the cooperation of the vertical drive component 5 and the adjusting bracket 4, has the advantage of keeping the cable in a straight state during winding and unwinding. The cable is inserted into and fixed inside the clamping member 606 and the limiting seat 702. The second motor 504 drives the lead screw 501 to rotate, causing the sliding block 502 to move the transmission push rod 503. The transmission push rod 503 then adjusts the cable laying assembly 6, limiting the cable position. Furthermore, the cable winding and unwinding device and method for subway electromechanical construction described in this invention, through the cooperation of the cable laying assembly 6 and the vertical drive component 5, has the advantage of convenient cable bending. The second motor 504 drives the lead screw 501 to rotate in opposite directions, and the transmission push rod 503 moves the sliding block 502. The movable support 601 moves, causing the sliding support 601 to drive the cable guide 605 to move up and down, so that the two cable guides 605 can be staggered vertically to bend the cable vertically. It can also control the third motor 604 to drive the reciprocating screw 603 to rotate in opposite directions, so that the cable guide 605 moves in opposite directions to form a horizontal stagger, thereby bending the cable left and right. The cable winding and unwinding device and method for subway electromechanical construction described in this invention has the advantage of preventing the cable from being pulled back when it is bent by setting a one-way limiting component 7. When the vertical drive component 5 and the cable guide component 6 work together to bend the cable, the cable will rub against the friction layer 704, thereby pulling the limiting closing block 703 inward to form a reduced trumpet shape to clamp and fix the cable, preventing it from being pulled back when the cable is bent and affecting the cable laid at the front end.
