When in use, the pay-out device is placed near the cable wellhead, and the communication cable can avoid friction with the wellhead when entering the cable well, preventing the cable from being scratched, playing a good protective and guiding role, and the operation is time-saving and labor-saving, reducing the difficulty of work, ensuring construction quality and improving construction efficiency. It is suitable for pre-buried cable wells, with a firm and stable structure and convenient and quick installation.

[0004] The traditional auxiliary wire-paying device for laying through-ground wires on railways has certain shortcomings when used. There are usually multiple bottom lines laid on the railway. However, when using the traditional auxiliary wire-paying device, it can only pay out a single bottom line at a time. When laying multiple bottom lines, repeated moving operations are required, which reduces its work efficiency. At the same time, the traditional auxiliary wire-paying device does not have a combined fixed structure. When used, it cannot be adjusted arbitrarily according to the number of railway tracks. It cannot be used for the wire-paying operations of multiple groups of railways, which reduces its flexibility when used. Secondly, the traditional auxiliary wire-paying device for laying through-ground wires on railways does not have an auxiliary fixed structure. When it performs the wire-paying operation, the ground wire is easily tangled and entangled, and manual wire-straightening operations are required. Summary of the Invention

[0005] The purpose of the present invention is to provide an auxiliary wire-laying device for laying a railway through-ground wire, which can solve the existing problems.

[0006] The problems solved by the present invention are:

[0007] 1. Railways usually have multiple bottom lines. However, traditional auxiliary pay-off devices can only pay off a single bottom line at a time. When laying multiple bottom lines, repeated movement operations are required, which reduces work efficiency.

[0008] 2. The traditional auxiliary pay-off device does not have a combined fixed structure. It cannot be adjusted according to the number of railway tracks during use and cannot be applied to pay-off operations on multiple railways, which reduces its flexibility during use.

[0009] 3. The auxiliary laying-out device for laying through-ground wires on traditional railways does not have an auxiliary fixing structure. When laying out the wires, the ground wires are prone to tangling and require manual line management.

[0010] The purpose of the present invention can be achieved through the following technical solutions:

[0011] An auxiliary wire-laying device for laying railway through-ground wires comprises a first base plate and a second base plate, wherein the first base plate is spliced and installed on one side of the second base plate, a first clamping seat is fixedly installed on the outer surface of the upper end of the first base plate, and a second clamping seat is fixedly installed on the outer surface of the upper end of the second base plate, and a winding rod for laying out the wire is movably installed on the inner sides of the second clamping seat and the first base plate, and a wire fixing clamp is provided on the outer surfaces of the upper ends of the first base plate and the second base plate near the front of the first clamping seat and the second clamping seat, and a telescopic plate is movably installed on the inner sides of the first base plate and the second base plate, and a docking sleeve for docking the winding rod is provided between the first clamping seat and the second clamping seat.

[0012] As a further technical solution of the present invention, the outer surfaces of both ends of the docking sleeve are provided with limit slots, the end of the winding rod is provided with a docking head used to cooperate with the limit slots, and the side of the docking sleeve is provided with a fixing bolt for locking the docking head. When the first base plate and the second base plate are spliced, the docking sleeve can be used to combine and fix the winding rods on the first card seat and the second card seat. When one winding rod rotates, it can drive the other winding rod to rotate, so that the laying operation of two sets of ground wires can be performed.

[0013] As a further technical solution of the present invention, telescopic grooves are provided inside the first and second bottom plates, and the length of the telescopic grooves is greater than the length of the telescopic plate. A push-pull slider is provided at the middle position of the lower end of the telescopic plate. The user pushes the push-pull slider to drive the telescopic plate to move and adjust the usable length of the telescopic plate. Because the length of the telescopic groove is greater than the length of the telescopic plate, the position movement of the telescopic plate is coordinated so that the first and second bottom plates both have a card slot docking structure.

[0014] As a further technical solution of the present invention, the bottoms of the first base plate, the second base plate and the telescopic plate are all provided with docking slots, and the lower parts of the first base plate and the second base plate are spliced and installed with two groups of moving parts, the moving parts include casters and splicing bases, the casters are movably installed at the lower part of the splicing bases, and when the telescopic plates of the first base plate and the second base plate are extended, the moving parts can be installed on the docking slots of the first base plate, the second base plate and the telescopic plate, and the first base plate and the second base plate form independent moving structures, so that the winding rods on the first base plate and the second base plate can be used independently, so that they are separated into two groups of pay-off devices.

[0015] As a further technical solution of the present invention, the bottoms of the first and second card seats are fixedly installed with fixed card seats, the first card seat and the first base plate, as well as the second card seat and the second base plate are docked and fixed through the fixed card seat, and the bottom of the first base plate is provided with a docking groove. The setting of the fixed card seat plays a fixing role in the installation of the first card seat and the first base plate, as well as the second card seat and the second base plate.

[0016] As a further technical solution of the present invention, a motor for driving the winding rod is provided at one end of the first clamping seat, and the motor and the first clamping seat are spliced and fixed by a fixing bolt. The splicing operation of the motor and the first clamping seat can be completed by using the fixing bolt. After the docking sleeve is fixed between the winding rods of the first clamping seat and the second clamping seat, the motor can be used to simultaneously drive the winding rods of the first clamping seat and the second clamping seat to rotate, so that they can perform synchronous pay-off operations of two sets of bottom lines.

[0017] As a further technical solution of the present invention, the upper ends of the first clamping seat and the second clamping seat are both provided with a slide groove for cooperating with the line fixing clamp, and the line fixing clamp includes a sliding frame, a lower clamping wheel and an upper clamping wheel, and the lower clamping wheel and the upper clamping wheel are both movably mounted on one side of the sliding frame, and the lower clamping wheel is movably mounted on the lower part of the upper clamping wheel. The movement of the lower clamping wheel and the upper clamping wheel can assist in positioning bottom lines of different calibers. When the bottom line is paid out, the lower clamping wheel and the upper clamping wheel rotate following the bottom line pay-out operation, and the bottom line is clamped between the lower clamping wheel and the upper clamping wheel to prevent it from being entangled. At the same time, the line fixing clamp is used to cooperate with the slide groove to move to a certain position, so that it can be adjusted accordingly according to the pay-out position of the bottom line.

[0018] As a further technical solution of the present invention, a docking slider used in conjunction with a slide groove is fixedly installed on the outer surface of the lower end of the sliding frame, and the lower clamping wheel and the sliding frame are docked by a fastening bolt. A lifting clamping seat is provided on the upper part of the upper clamping wheel, and the lifting clamping seat and the sliding frame are connected by a lifting bolt. The user can drive the upper clamping wheel up and down by rotating the lifting bolt and utilizing the threaded structure between the lifting bolt and the sliding frame to cooperate with the lifting clamping seat. At the same time, the lower clamping wheel can be moved up and down by utilizing the slide groove on the sliding frame. After the lower clamping wheel moves to the corresponding position, the fastening bolt is rotated to lock it.

[0019] As a further technical solution of the present invention, a turning handle is movably installed on one side of the second clamping seat, and splicing clamps are provided on both sides of the telescopic plate. Both ends of the splicing clamps are arc-shaped structures. The splicing of the first base plate and the second base plate can be reinforced by using the splicing clamps. Secondly, by turning the turning handle, the winding rod can be manually driven to perform the line-releasing operation.

[0020] Beneficial effects of the present invention:

[0021] 1. By setting the first clamping seat and the second clamping seat, when the auxiliary wire-laying device for laying the railway through-ground wire is used, the winding rods on the first clamping seat and the second clamping seat are used to make it have a double wire-laying structure. During operation, the first base plate and the second base plate under the first clamping seat and the second clamping seat are spliced and fixed by the telescopic plate and the splicing clamp head. The user pushes the push-pull slider to drive the telescopic plate to move and adjust the use length of the telescopic plate. Because the length of the telescopic slot is greater than the length of the telescopic plate, the position movement of the telescopic plate makes the first base plate and the second base plate both have a card slot docking structure, which is convenient for its assembly operation, and the fixing bolt can be used to complete the electrical connection. The motor and the first card seat are spliced together, and the winding rods on the first card seat and the second card seat can be combined and fixed by using the docking card sleeve. When one winding rod rotates, it can drive the other winding rod to rotate, so that the wire-laying operation of two sets of ground wires can be performed. After the docking card sleeve is fixed between the winding rods of the first card seat and the second card seat, the motor can be used to simultaneously drive the winding rods of the first card seat and the second card seat to rotate, so that they can perform the synchronous wire-laying operation of two sets of bottom lines, and the moving parts of the first card seat and the second card seat are clamped on the track, and the movement of the first card seat and the second card seat is coordinated to complete the double wire-laying operation of the railway, thereby improving the laying efficiency of the railway through-ground wire.

[0022] 2. By setting a moving part, when the auxiliary pay-out device for laying the railway through-ground wire is used, the user can arbitrarily disassemble and assemble the first clamping seat and the second clamping seat according to the number of tracks. After the first clamping seat and the second clamping seat are disassembled, two independent pay-out mechanisms are formed. After the first clamping seat and the second clamping seat are combined, a double-line pay-out structure is formed. During the disassembly operation, the user pushes the push-pull slider to drive the push-pull slider to move the telescopic plate, thereby removing the telescopic plate from the slot of the first base plate or the second base plate, and then uses the docking clamp head to connect the first base plate to the second base plate. After the bottom plate and the second bottom plate are separated and the telescopic plate is moved out from the first bottom plate or the second bottom plate, the docking slots of the first bottom plate, the second bottom plate and the telescopic plate are used in conjunction with the splicing socket of the moving part to complete the combined fixation of the moving part. The extended telescopic plate allows the first bottom plate and the second bottom plate to adapt to the width of the railway, allowing them to perform mobile line-laying operations. By using the setting of the moving part and cooperating with the split first socket and second socket, the auxiliary line-laying device for laying the railway through-ground wire has a combined fixed structure, which improves its flexibility during line-laying operations.

Because the length of the telescopic groove is greater than the length of the telescopic plate 18, the position movement of the telescopic plate 18 is coordinated, so that the first bottom plate 1 and the second bottom plate 2 both have a card slot docking structure.

[0036] The bottoms of the first base plate 1, the second base plate 2 and the telescopic plate 18 are all provided with docking slots 24, and the lower parts of the first base plate 1 and the second base plate 2 are spliced and installed with two groups of moving parts 3, the moving parts 3 include casters 16 and splicing card seats 17, the casters 16 are movably installed at the lower part of the splicing card seats 17, when the telescopic plates 18 of the first base plate 1 and the second base plate 2 are extended, the moving parts 3 can be installed on the docking slots 24 of the first base plate 1, the second base plate 2 and the telescopic plate 18, the first base plate 1 and the second base plate 2 form an independent moving structure, so that the winding rods 21 on the first base plate 1 and the second base plate 2 can be used independently, so that they can be separated into two groups of pay-off devices.

[0037] The bottom of the first card seat 7 and the second card seat 4 are fixedly installed with a fixed card seat 19.

The fixing bolt 22 can be used to complete the splicing operation of the motor 6 and the first card seat 7. After the docking sleeve 28 is fixed between the winding rod 21 of the first card seat 7 and the second card seat 4, the motor 6 can be used to simultaneously drive the winding rod 21 of the first card seat 7 and the second card seat 4 to rotate, so that they can perform the synchronous pay-off operation of two sets of bottom lines.

[0039] The upper ends of the first clamping seat 7 and the second clamping seat 4 are both provided with a slide groove for cooperating with the line fixing clamp 8. The line fixing clamp 8 includes a sliding frame 15, a lower clamping wheel 11 and an upper clamping wheel 12. The lower clamping wheel 11 and the upper clamping wheel 12 are both movably mounted on one side of the sliding frame 15. The lower clamping wheel 11 is movably mounted on the lower part of the upper clamping wheel 12. The movement of the lower clamping wheel 11 and the upper clamping wheel 12 can assist in positioning bottom lines of different calibers. When the bottom line is paid out, the lower clamping wheel 11 and the upper clamping wheel 12 rotate following the bottom line pay-off operation. The bottom line is clamped between the lower clamping wheel 11 and the upper clamping wheel 12 to prevent it from being entangled. At the same time, the line fixing clamp 8 is used to cooperate with the slide groove to move to a certain position, so that it can be adjusted accordingly according to the pay-off position of the bottom line.

[0040] The outer surface of the lower end of the sliding frame 15 is fixedly installed with a docking slider 10 used in conjunction with the slide groove.

[0042] The auxiliary pay-out device for laying the railway through-ground wire is provided with a first clamping seat 7 and a second clamping seat 4. When the auxiliary pay-out device for laying the railway through-ground wire is used, the winding rod 21 on the first clamping seat 7 and the second clamping seat 4 is used to make it have a double pay-out structure. During operation, the telescopic plate 18 and the splicing clamp head 23 are used to splice and fix the first bottom plate 1 and the second bottom plate 2 under the first clamping seat 7 and the second clamping seat 4. The user pushes the push-pull slider 25 so that the push-pull slider 25 drives the telescopic plate 18 to move and adjust the use length of the telescopic plate 18. Because the length of the telescopic slot is greater than the length of the telescopic plate 18, the position movement of the telescopic plate 18 is coordinated so that the first bottom plate 1 and the second bottom plate 2 both have a slot docking structure, which is convenient for assembly operation, and then the fixing bolt is used. 22 can complete the splicing operation of the motor 6 and the first card seat 7, and the winding rods 21 on the first card seat 7 and the second card seat 4 can be combined and fixed by using the docking card sleeve 28. When one winding rod 21 rotates, it can drive the other winding rod 21 to rotate, so that the pay-off operation of laying two sets of ground wires can be performed. After the docking card sleeve 28 is fixed between the winding rods 21 of the first card seat 7 and the second card seat 4, the motor 6 can simultaneously drive the winding rods 21 of the first card seat 7 and the second card seat 4 to rotate, so that they can perform the synchronous pay-off operation of the two sets of bottom lines, and the moving parts 3 of the first card seat 7 and the second card seat 4 are clamped on the track, and the movement of the first card seat 7 and the second card seat 4 is coordinated to complete the double pay-off operation of the railway, thereby improving the laying efficiency of the railway through-ground wire;

After the lower clamping wheel 11 moves to the corresponding position, rotate the fastening bolt 9 to lock it to prevent the cable from falling off. During the bottom line pay-off operation, the lower clamping wheel 11 and the upper clamping wheel 12 rotate following the bottom line pay-off operation. The bottom line is clamped between the lower clamping wheel 11 and the upper clamping wheel 12 to prevent it from being entangled. At the same time, the fixed line clamp 8 is used to cooperate with the slide groove to move to a certain position, so that it can be adjusted accordingly according to the pay-off position of the bottom line, thereby improving the pay-off effect of the auxiliary pay-off device for laying the railway through-ground wire.
