Description

Technical Field

[0001] The present invention relates to the technical field of trough-type cable tray fittings for cable line laying, and particularly to a trough-type cable tray structure for cable line laying and a using method thereof. Background Art

[0002] The trough-type cable tray, as the core carrier for laying power, communication, control and other cable lines, is widely used in industrial factories, data centers, intelligent buildings, substations and other scenarios. Its enclosed structure and metal tray with a cover plate can effectively protect the cables from dust, moisture, mechanical damage and electromagnetic interference. However, it is found in use that it cannot automatically and conveniently guide the laying of cable lines on the trough-type cable tray. Because the laying of most cables on the trough-type cable tray is carried out by manual dragging or simple pulley-assisted manual dragging, it does not have convenient cable line guiding and laying, which is time-consuming and laborious, thus reducing the cable laying efficiency. For example, the prior art with the publication number CN217508158U provides a top cover locking structure for a trough-type cable tray, which includes a top cover and a lower trough body. Side turning grooves are opened on both sides of the top cover, and movable plates are rotatably connected to the inner sides of the side turning grooves through fixed shafts; connection blocks are arranged on the upper parts of both sides of the lower trough body, connection card slots are opened at positions corresponding to the connection blocks on the movable plates, a lever guiding groove is opened on one side of the connection card slot, a pin guiding groove is opened on the inner side of the lever guiding groove, a locking component is arranged in the pin guiding groove and the lever guiding groove, a first pin hole is opened at a position close to the locking component in the connection card slot, a second pin hole is opened at a position corresponding to the first pin hole on the connection block, and both the first pin hole and the second pin hole are adapted to the locking component. The fixed connection between the top cover and the lower trough body is completed through the locking component, with a simple structure and more convenient operation, greatly improving the installation efficiency of the cable tray and enhancing the connection stability between the top cover and the lower trough body. It is known from the actual use of the above prior art that it mainly completes the fixed connection between the top cover and the lower trough body through the locking component, with a simple structure. However, it is found in use that it cannot automatically and conveniently guide the laying of cable lines on the trough-type cable tray. Because the laying of most cables on the trough-type cable tray is carried out by manual dragging or simple pulley-assisted manual dragging, it is time-consuming and laborious, thus reducing the cable laying efficiency. Therefore, according to the actual use situation, the above prior art is improved. Summary of the Invention

[0013] Furthermore: The sliding anti-slip wheel includes raised rubber friction lines provided on the outer side wall.

[0014] A method of using a trough-type bridge structure for cable line laying, the method comprising the following steps: Step 1: The operator first manually moves the movable clamping plate provided on the outer wall of the second screw through the movable round hole opened thereon towards the top clamping plate on the outer wall of the second screw, so that the distance between the movable clamping plate and the top clamping plate is used to clamp the end of the trough-type bridge base. Manually rotate the first fixing cap threadedly connected to the bottom of the movable clamping plate adjacent to one end of the second screw to abut against the outer wall of the bottom of the movable clamping plate for abutting and fixing. Manually rotate the second fixing cap threadedly connected to the bottom of the rotating support bracket adjacent to one end of the third screw to abut against the outer wall of the bottom of the rotating support bracket for fixing, so that the side walls on one side of the top of the rotating support bracket are all rotatably connected with third sliding roller rods to be in the same horizontal position as the end of the trough-type bridge base. An activity round hole is opened at the bottom of the rotating support bracket, so that the side walls on one side of the top of the rotating support bracket can be rotatably connected with third sliding roller rods to adjust the rotation angle to adapt to the turning of the trough-type bridge base interface; Step 2: Further, the operator manually places the cable guiding and leading component on both sides of the inner wall of the trough-type bridge base. Since two sets of sliding traction components with the same structure are symmetrically arranged on the inner cavity side walls of the two square through chutes, only the operation method of one set of sliding traction components is described. The operator manually rotates a set of rotating screws, which are supported and rotated by being rotatably connected to the side wall of one set of support blocks at one end and to the support shell at the other end. The rotation of the rotating screw drives the connecting plate threadedly connected to one side wall to drive the installation shell to perform a linear movement in the inner cavity of the square through chute by slidingly connecting the outer wall of the execution end of the support sliding round rod on the other side wall of the connecting plate. At the same time, the installation shell performs a linear movement by slidingly connecting to the inner cavity side wall at one end of the support shell, so that the sliding anti-slip wheel provided on the installation shell is adjusted to abut against the side wall of the trough-type bridge base. When the spring provided on one side wall of the first slider is subjected to the force of the sliding anti-slip wheel abutting against the trough-type bridge base, the first slider provided on the other side wall of the installation shell drives the spring to be compressed in the direction of the connecting plate on which the first slider is slidingly connected to both side walls. The spring is used to avoid excessive abutting force, resulting in the sliding anti-slip wheel overly abutting against the side wall of the trough-type bridge base, increasing the rotational friction force of the sliding anti-slip wheel, and also playing a certain shock absorption role when the sliding anti-slip wheel rotates. By the above operation method of one set of sliding traction components, the other set of sliding traction components abuts against the side wall on the other side of the trough-type bridge base, completing the installation of the cable guiding and leading component on both sides of the inner wall of the trough-type bridge base; Step 3: Then, manually by the operator, the end of the cable line body passes through the third sliding roller rod and extends and is placed on the outer side wall of the top of the support shell, so that the bottom of the end of the cable line body close to the end contacts the third sliding roller rod, the first sliding roller rod and the second sliding roller rod to form an arc layout, avoiding the cable line body from rubbing against the corner bend of the trough type bridge base during sliding and being worn. Then, manually by the operator, rotate the first screw rod rotatably connected to the side wall of one side of the top of the T-shaped support plate, so that the first screw rod drives the pressing block threadedly connected to the side wall on the other side through threaded movement to perform linear movement up and down by slidingly connecting to the side wall at the middle position of the top of the T-shaped support plate and the outer wall of the execution end of the second slider on one side wall of the pressing block, so that the rubber friction pad provided on the outer side wall of the bottom of the pressing block abuts and fixes on the end of the cable line body through linear movement up and down. The rubber friction pad improves a certain frictional force and avoids damaging the cable line body due to excessive extrusion. The support shell includes a camera provided at the top of one side adjacent to the support sliding round rod, which captures image information through existing technology and converts it into an electrical signal to capture the position information in front of it, facilitating the motor execution end to stop rotating at the turning interface of the cable line body. The sliding traction parts are of two groups with the same structure and operation mode. The electrical signal is transmitted through the plc controller and triggers the first bevel gear connected to one end of the motor execution end to rotate by being rotatably connected to the spaced side walls of the inner cavity of the top of the installation shell through one end of the motor execution end. The rotation of the first bevel gear drives the second bevel gear meshed with the bottom of one side to rotate by being rotatably connected to the bottom side wall of the inner cavity of the top of the installation shell through the round rod embedded at the bottom of the second bevel gear. And the round rod embedded at the bottom of the second bevel gear extends and is rotatably connected to the bottom side wall of the inner cavity of the movable groove opened at one end of the bottom of the installation shell to support rotation. The rotation of the second bevel gear drives the round rod embedded at the bottom to rotate the sliding anti-skid wheel embedded on the outer side wall of one end of the bottom of the inner cavity of the movable groove opened at one end of the bottom of the installation shell adjacent to the installation shell, so that the rotation of the two sliding anti-skid wheels drives the cable line body fixed through the above operations to automatically guide and lay on both sides of the inner wall of the trough type bridge base towards the other end of the trough type bridge base; Step 4: When approaching the turning point of the trough-type cable tray base interface, capture the position information of the trough-type cable tray base in front through a camera, convert it into an electrical signal and send it to the plc controller. The plc controller then transmits the electrical signal and triggers the motor execution end to stop rotating. The sliding anti-slip wheel includes raised rubber friction patterns on its outer sidewall for anti-slip during rotation and has a certain damping effect. Even if it is not completely braked, it can provide a certain resistance through continuous friction to better stop and brake the sliding anti-slip wheel. Then, the adjustable auxiliary wheel assembly, which can be provided in multiple numbers, is set at the turning point of the trough-type cable tray base interface. Manually operate to make the moving clamping plate and the top clamping plate approach each other and clamp the sidewall at the turning point of the trough-type cable tray base interface. Through the movable round holes opened at the bottom of the rotating support plate frame, both sidewalls on one side of the top of the rotating support plate frame are rotatably connected with the third sliding roller rod to adjust the rotation angle to adapt to the angle at the turning point of the trough-type cable tray base interface. Then, manually rotate to make the second fixed cap abut against the outer sidewall at the bottom of the rotating support plate frame for fixation when the rotation angle adjustment of the rotating support plate frame is completed, so that the cable line body contacts the third sliding roller rod at the turning point to avoid abrasion when the cable line body slides at the corner bend. Then, through the above-mentioned fixing method of the cable guiding and leading component, it is re-abutted against both sides of the inner wall of the trough-type cable tray base, and the cable line body is automatically guided and led to run towards the other end of the trough-type cable tray base in the same way as above. Through the above operations, it is convenient to automatically and conveniently guide and lay the cable line body on the trough-type cable tray, avoiding the time-consuming and laborious manual dragging or simple pulley-assisted manual dragging of most cables when laying on the trough-type cable tray, improving the cable laying efficiency and the convenience of operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention facilitates the automatic and convenient guiding and laying of the cable line on the trough-type cable tray through the cooperation of the cable guiding and leading component and the adjustable auxiliary wheel assembly, avoiding the time-consuming and laborious manual dragging or simple pulley-assisted manual dragging of most cables when laying on the trough-type cable tray, improving the cable laying efficiency and the convenience of operation.

[0025] Please refer to Figure 1-7 , the present invention provides a technical solution: a trough-type bridge structure for cable line laying, comprising a trough-type bridge base 1, a trough-type bridge cover 2, an adjustment auxiliary wheel assembly 3, a chute 4, and a cable traction guiding assembly 5; An adjustment auxiliary wheel assembly 3 is provided on the bottom side wall at one end of the outer wall of the trough-type bridge base 1; Two groups of chutes 4 with the same structure are opened at the top of the outer side walls on both sides of the trough-type bridge base 1, and the trough-type bridge cover 2 is slidably connected to the side walls of both groups of chutes 4; A cable traction guiding assembly 5 is provided on the inner cavity side wall of the trough-type bridge base 1. By cooperating the cable traction guiding assembly 5 with the adjustment auxiliary wheel assembly 3, it is convenient to automatically and conveniently guide and lay the cable line on the trough-type bridge, avoiding the manual dragging or simple pulley-assisted manual dragging of most cables when laying on the trough-type bridge, which is time-consuming and laborious, improving the cable laying efficiency and being convenient to operate.

[0026] Among them, preferably, the cable traction guiding assembly 5 includes a support shell 51 provided. Two sets of square through chutes 55 with the same structure are opened on both side walls of the support shell 51.

The other ends of the two sets of rotating screw rods 56 are rotatably connected to one side wall of the support shell 51. And two sets of support sliding round rods 58 with the same structure are symmetrically arranged on both side walls of the other set of support blocks 54. The other ends of the two sets of support sliding round rods 58 are arranged on the other side wall of the support shell 51.

And two sets of second sliding roller rods 53 with the same structure are rotatably connected to both top side walls of the support shell 51. And a cable line body 59 is provided on the outer side wall of the top of the support shell 51. By manually passing the end of the cable line body 59 through the third sliding roller rod 38 by the operator and extending it onto the outer side wall of the top of the support shell 51, the bottom of the end of the cable line body 59 close to the end contacts the third sliding roller rod 38, the first sliding roller rod 57 and the second sliding roller rod 53 to form an arc layout, avoiding the cable line body 59 being worn by friction at the corner bend of the trough type bridge base 1 during sliding.

[0027] Preferably, the sliding traction member 50 includes a mounting shell 501 that is slidably connected to the inner cavity side wall of one end of the support shell 51. One side wall of the mounting shell 501 extends to the outer side wall of one end of the support shell 51, and a first slider 508 is provided on the other side wall of the mounting shell 501. The side walls of the first slider 508 are slidably connected to a connecting plate 507. Both side walls of the connecting plate 507 extend to the outer side walls on both sides of the square through chute 55. One side wall of the connecting plate 507 is threadedly connected to a matching first rotating screw 56, and the other side wall of the connecting plate 507 is slidably connected to the outer wall of the execution end of the support sliding round rod 58. A support plate 503 is provided on the inner cavity side wall of the top of the mounting shell 501. A motor 502 is installed on the side wall of the support plate 503. One end of the execution end of the motor 502 is rotatably connected to the spaced side wall of the inner cavity of the top of the mounting shell 501. One end of the execution end of the motor 502 is connected to a first bevel gear 506. A matching second bevel gear 504 is engaged with one side at the bottom of the first bevel gear 506. The round rod embedded at the bottom of the second bevel gear 504 is rotatably connected to the bottom side wall of the inner cavity of the top of the mounting shell 501. The round rod embedded at the bottom of the second bevel gear 504 extends and is rotatably connected to the bottom side wall of the inner cavity of the movable groove opened at the bottom of one end of the mounting shell 501. A sliding anti-slip wheel 505 is embedded on the outer side wall at one end of the bottom of the inner cavity of the movable groove opened at the bottom of one end of the mounting shell 501 adjacent to the round rod embedded at the bottom of the second bevel gear 504. By placing the cable guiding and traction assembly 5 on both sides of the inner wall of the trough-type bridge base 1, since the inner cavity side walls of its two square through chutes 55 are symmetrically provided with two sliding traction members 50 of the same structure, only the operation method of one set of sliding traction members 50 is described. By manually rotating a set of rotating screws 56 by an operator, with one end rotatably connected to the side wall of a set of support blocks 54 and the other end rotatably connected to the support shell 51 for support rotation, the rotation of the rotating screw 56 drives the connecting plate 507 threadedly connected to one side wall to drive the mounting shell 501 to perform a linear movement supported by the outer wall of the execution end of the support sliding round rod 58 through the other side wall of the connecting plate 507 sliding in the square through chute 55. At the same time, the mounting shell 501 performs a linear movement by slidingly connecting to the inner cavity side wall of one end of the support shell 51 through the linear movement, so that the sliding anti-slip wheel 505 provided on the mounting shell 501 is adjusted to abut against the side wall of the trough-type bridge base 1 through the linear movement. When the spring 5081 provided on one side wall of the first slider 508 is subjected to the force of the sliding anti-slip wheel 505 abutting against the trough-type bridge base 1, the first slider 508 provided on the other side wall of the mounting shell 501 drives the spring 5081 to be compressed in the direction where the connecting plate 507 is slidably connected to the side walls of the first slider 508. The spring 5081 avoids excessive abutting force, causing the sliding anti-slip wheel 505 to overly abut against the side wall of the trough-type bridge base 1, increasing the rotational friction force of the sliding anti-slip wheel 505, and also playing a certain shock-absorbing role. Through the above operation method of one set of sliding traction members 50, the other set of sliding traction members 50 abuts against the side wall of the other side of the trough-type bridge base 1.Complete the installation of the cable guiding and leading component 5 on both sides of the inner wall of the trough-type bridge base 1.

By the operator manually rotating the first screw 523 rotatably connected to the side wall of one side of the top of the T-shaped support plate 521, the first screw 523 drives the matching pressing block 522 threadedly connected to the other side wall to perform linear movement up and down through the sliding connection to the side wall at the middle position of the top of the T-shaped support plate 521 and the sliding connection of one side wall of the pressing block 522 to the outer wall of the execution end of the second slider 524, so that the rubber friction pad 5221 provided on the outer side wall of the bottom of the pressing block 522 abuts and fixes the end of the cable line body 59 through the linear movement up and down. The rubber friction pad 5221 improves a certain frictional force and avoids damaging the cable line body 59 due to excessive extrusion.

[0029] Preferably, the adjusting auxiliary wheel assembly 3 includes a top clamping plate 31. On one side wall at the bottom of the top clamping plate 31, a second screw 32 is provided.

On one side wall at the top of the rotating support plate frame 37, a third sliding roller rod 38 is rotatably connected. By manually moving the moving clamping plate 36 provided on the outer side wall of the second screw 32 through the provided movable round hole close to the top clamping plate 31 on the outer side wall of the second screw 32, the distance between the moving clamping plate 36 and the top clamping plate 31 when they approach each other clamps the end of the trough-type bridge base 1. By manually rotating the first fixed cap 33 threadedly connected to the bottom of the moving clamping plate 36 at one end of the second screw 32 to abut against the outer side wall at the bottom of the moving clamping plate 36 for abutting and fixing, and by manually rotating the second fixed cap 35 threadedly connected to the bottom of the rotating support plate frame 37 at one end of the third screw 34 to abut against the outer side wall at the bottom of the rotating support plate frame 37 for fixing, the third sliding roller rods 38 rotatably connected to one side wall at the top of the rotating support plate frame 37 are made to be in the same horizontal position as the end of the trough-type bridge base 1. An activity round hole is provided at the bottom of the rotating support plate frame 37, which enables the third sliding roller rods 38 rotatably connected to one side wall at the top of the rotating support plate frame 37 to adjust the rotation angle to adapt to the turning of the interface of the trough-type bridge base 1.

[0030] Preferably, the pressing block 522 includes a rubber friction pad 5221 provided on the outer side wall at the bottom. Through the rubber friction pad 5221 provided on the outer side wall at the bottom of the pressing block 522, it abuts and fixes against the end of the cable line body 59 through the up-and-down linear movement. The rubber friction pad 5221 improves a certain frictional force and avoids damaging the cable line body 59 due to excessive extrusion.

[0031] Preferably, the first slider 508 includes a spring 5081 provided on one side wall. The other end of the spring 5081 is provided on the side wall of the connecting plate 507 adjacent to one end of the mounting shell 501. Through the spring 5081, excessive abutting force is avoided, which may cause the sliding anti-skid wheel 505 to overly abut against the side wall of the trough-type bridge base 1, increasing the rotational frictional force of the sliding anti-skid wheel 505, and it also helps to play a certain shock-absorbing role when the sliding anti-skid wheel 505 rotates.

[0032] Preferably, the support shell 51 includes a camera 511 disposed at the top of one side adjacent to the support sliding round rod 58. Through the existing image capture information technology, the camera 511 in the support shell 51 adjacent to the top of one side of the support sliding round rod 58 converts the electrical signal to capture the position information in front of it, facilitating the motor 502 execution end to stop rotating at the turning interface of the cable line body 59.

[0033] Preferably, the sliding anti-slip wheel 505 includes convex rubber friction lines 5051 provided on the outer sidewall. The convex rubber friction lines 5051 provided on the outer sidewall of the sliding anti-slip wheel 505 facilitate anti-slip and a certain damping effect during rotation. Even if it is not completely braked, it can provide a certain resistance through continuous friction to better stop the sliding anti-slip wheel 505 from braking.

[0034] A usage method of a trough-type bridge structure for cable line laying, the method comprising the following steps: Step 1: The operator first manually moves the moving clamp 36 provided on the outer sidewall of the second screw 32 close to the top clamp 31 through the movable round hole opened on the outer sidewall of the second screw 32, so that the distance between the moving clamp 36 and the top clamp 31 when they approach each other clamps the end of the trough-type bridge base 1. Manually rotate the first fixed cap 33 threadedly connected to the bottom of the moving clamp 36 adjacent to one end of the second screw 32 to abut against the outer sidewall of the bottom of the moving clamp 36 for abutting and fixing. Manually rotate the second fixed cap 35 threadedly connected to the bottom of the rotating support frame 37 adjacent to one end of the third screw 34 to abut against the outer sidewall of the bottom of the rotating support frame 37 for fixing, so that the sidewalls on one side of the top of the rotating support frame 37 are all rotatably connected to the third sliding roller rod 38 and are in the same horizontal position as the end of the trough-type bridge base 1. The rotating support frame 37 is provided with a movable round hole at the bottom, which can enable the sidewalls on one side of the top of the rotating support frame 37 to be rotatably connected to the third sliding roller rod 38 for adjusting the rotation angle to adapt to the turning of the interface of the trough-type bridge base 1; Step 2: Further, the operator manually places the cable guiding and deflecting component 5 on both sides of the inner wall of the trough-type bridge base 1. Since two sets of sliding traction parts 50 with the same structure are symmetrically arranged on the inner side walls of the inner cavities of the two sets of square through chutes 55, only the operation method of one set of sliding traction parts 50 is used. By manually rotating a set of rotating screws 56 by the operator, the rotating screws 56 are supported and rotated by being rotatably connected to the side wall of a set of support blocks 54 at one end and to the support shell 51 at the other end. The rotation of the rotating screws 56 drives the connecting plate 507 threadedly connected to one side wall to drive the installation shell 501 to perform a linear movement in the inner cavity of the square through chute 55, and the other side wall of the connecting plate 507 is slidably connected to the outer wall of the execution end of the support sliding round rod 58 for support. At the same time, the installation shell 501 performs a linear movement by the linear movement and slides in the inner cavity side wall at one end of the support shell 51, so that the installation shell 501 adjusts the provided sliding anti-slip wheel 505 to abut against the side wall of the trough-type bridge base 1 by the linear movement. When the spring 5081 provided on one side wall of the first slider 508 receives the force of the sliding anti-slip wheel 505 abutting against the trough-type bridge base 1, the first slider 508 provided on the other side wall of the installation shell 501 drives the spring 5081 to be compressed in the direction of the connecting plate 507 where the first slider 508 is slidably connected to both side walls. By the spring 5081, excessive abutting force is avoided, which may cause the sliding anti-slip wheel 505 to overly abut against the side wall of the trough-type bridge base 1, increasing the rotational friction force of the sliding anti-slip wheel 505, and it also helps to play a certain shock-absorbing role when the sliding anti-slip wheel 505 rotates. Through the operation method of the above-mentioned one set of sliding traction parts 50, the other set of sliding traction parts 50 abuts against the side wall of the other side of the trough-type bridge base 1, completing the installation of the cable guiding and deflecting component 5 on both sides of the inner wall of the trough-type bridge base 1; Step 3: Then, manually by the operator, the end of the cable line body 59 passes through the third sliding roller rod 38 and extends to the outer side wall of the top of the support shell 51, so that the bottom of the end of the cable line body 59 close to the end touches the third sliding roller rod 38, the first sliding roller rod 57 and the second sliding roller rod 53 to form an arc layout, avoiding the cable line body 59 from being worn by rubbing against the corner bend of the trough type cable tray base 1 during sliding. Then, manually by the operator, rotate the first screw 523 rotatably connected to the side wall of one side of the top of the T-shaped support plate 521, so that the first screw 523 drives the pressing block 522 threadedly connected to the side wall of the other side through threaded movement to perform a linear up and down movement by slidingly connecting to the side wall of the middle position of the top of the T-shaped support plate 521 and the outer wall of the execution end of the second slider 524 on the side wall of the pressing block 522, so that the rubber friction pad 5221 provided on the outer side wall of the bottom of the pressing block 522 is abutted and fixed to the end of the cable line body 59 through the linear up and down movement. The rubber friction pad 5221 provides a certain amount of friction and avoids damaging the cable line body 59 due to excessive extrusion. The support shell 51 includes a camera 511 provided on the top of one side adjacent to the support sliding round rod 58. Through the existing image capture information technology, it converts the electrical signal to capture the position information in front of it, facilitating the motor 502 execution end to stop rotating at the turning interface of the cable line body 59. The sliding traction member 50 has two sets of the same structure and operation method. It transmits the electrical signal through the plc controller and triggers the first bevel gear 506 connected to one end of the execution end of the motor 502 to support and rotate through the side wall of the inner cavity of the top of the installation shell 501 at intervals. The rotation of the first bevel gear 506 drives the second bevel gear 504 meshed with the bottom of one side to support and rotate through the round rod embedded at the bottom of the second bevel gear 504 and the side wall of the bottom of the inner cavity of the top of the installation shell 501. And the round rod embedded at the bottom of the second bevel gear 504 extends and is rotatably connected to the bottom side wall of the inner cavity of the movable groove opened at one end of the bottom of the installation shell 501 to support and rotate. The rotation of the second bevel gear 504 drives the round rod embedded at the bottom to rotate the sliding anti-skid wheel 505 embedded on the outer side wall of one end of the bottom of the inner cavity of the movable groove opened at one end of the bottom of the installation shell 501 adjacent to it, so that the rotation of the two sliding anti-skid wheels 505 drives the cable line body 59 fixed through the above operations to automatically guide and lay towards the other end of the trough type cable tray base 1 on both sides of the inner wall of the trough type cable tray base 1; Step 4: When approaching the turning point of the interface of the trough cable tray base 1, the position information of the trough cable tray base 1 in front is captured by the camera 511 and converted into an electrical signal to the plc controller. The plc controller then transmits the electrical signal and triggers the execution end of the motor 502 to stop rotating. The sliding anti-slip wheel 505 includes raised rubber friction lines 5051 provided on the outer side wall, which is convenient for anti-slip during rotation and has a certain damping effect. Even if it is not fully braked, it can provide a certain resistance through continuous friction to make the sliding anti-slip wheel 505 stop braking better. Then, the adjustable auxiliary wheel assembly 3, which can be provided in multiple numbers, is set at the turning point of the interface of the trough cable tray base 1. Through the above operations, the distance between the moving clamping plate 36 and the top clamping plate 31 is manually made to clamp the side wall at the turning point of the interface of the trough cable tray base 1. Through the movable round hole opened at the bottom of the rotating support plate frame 37, the side walls on one side of the top of the rotating support plate frame 37 are all rotatably connected with the third sliding roller rod 38 to adjust the rotation angle to adapt to the angle at the turning point of the interface of the trough cable tray base 1. Then, by manually rotating, the second fixed cap 35 is made to abut against the outer side wall of the bottom of the rotating support plate frame 37 for fixing when the rotation angle adjustment of the rotating support plate frame 37 is completed. The cable line body 59 contacts the third sliding roller rod 38 at the turning point, avoiding abrasion when the cable line body 59 slides at the corner bend. Then, through the fixing method of the above cable guiding and leading component 5, it is re-abutted against both sides of the inner wall of the trough cable tray base 1, and the above-mentioned same automatic guiding and leading cable line body 59 is laid towards the other end of the trough cable tray base 1. Through the above operations, it is convenient to automatically and conveniently guide and lay the cable line body 59 on the trough cable tray, avoiding the time-consuming and laborious manual dragging or simple pulley-assisted manual dragging of most cables when laying on the trough cable tray, improving the laying efficiency of the cables and the convenience of the operation.

[0035] Embodiment: When the work starts, the operator first manually moves the moving clamping plate 36 provided on the outer side wall of the second screw 32 through the opened movable round hole towards the top clamping plate 31 on the outer side wall of the second screw 32, so that the distance between the moving clamping plate 36 and the top clamping plate 31 clamps the end of the trough cable tray base 1. By manually rotating the first fixed cap 33 threadedly connected to the bottom of the moving clamping plate 36 adjacent to one end of the second screw 32, it abuts against the outer side wall of the bottom of the moving clamping plate 36 for abutting and fixing. By manually rotating the second fixed cap 35 threadedly connected to the bottom of the rotating support plate frame 37 adjacent to one end of the third screw 34, it abuts against the outer side wall of the bottom of the rotating support plate frame 37 for fixing, so that the side walls on one side of the top of the rotating support plate frame 37 are all rotatably connected with the third sliding roller rod 38 to be in the same horizontal position as the end of the trough cable tray base 1. The bottom of the rotating support plate frame 37 is provided with a movable round hole, which can make the side walls on one side of the top of the rotating support plate frame 37 be all rotatably connected with the third sliding roller rod 38 to adjust the rotation angle to adapt to the turning point of the interface of the trough cable tray base 1; Further, the operator manually places the cable guiding and leading component 5 on both sides of the inner wall of the trough-type bridge base 1. Since two sets of sliding traction members 50 with the same structure are symmetrically arranged on the inner cavity side walls of the two sets of square through chutes 55, only one set of sliding traction members 50 is operated. By manually rotating a set of rotating screws 56, which are supported and rotated by being rotatably connected to the side wall of a set of support blocks 54 at one end and to the support shell 51 at the other end, the rotation of the rotating screw 56 drives the connecting plate 507 threadedly connected to one side wall to drive the mounting shell 501 to perform a linear movement supported by slidingly connecting the outer wall of the execution end of the support sliding round rod 58 through the other side wall of the connecting plate 507 inside the square through chute 55. At the same time, the mounting shell 501 performs a linear movement by slidingly connecting to the inner cavity side wall at one end of the support shell 51 through the linear movement, so that the sliding anti-slip wheel 505 provided on the mounting shell 501 is adjusted to abut against the side wall of the trough-type bridge base 1 through the linear movement. When the force of the sliding anti-slip wheel 505 abutting against the trough-type bridge base 1 is received by the spring 5081 provided on one side wall of the first slider 508, the first slider 508 provided on the other side wall of the mounting shell 501 drives the spring 5081 to be compressed in the direction of the connecting plate 507 where the first slider 508 is slidingly connected to both side walls. By means of the spring 5081, excessive abutting force is avoided, which may cause the sliding anti-slip wheel 505 to overly abut against the side wall of the trough-type bridge base 1, increasing the rotational friction force of the sliding anti-slip wheel 505, and it also helps to play a certain shock-absorbing role when the sliding anti-slip wheel 505 rotates. Through the operation mode of the above-mentioned set of sliding traction members 50, the other set of sliding traction members 50 abuts against the side wall of the other side of the trough-type bridge base 1, completing the installation of the cable guiding and leading component 5 on both sides of the inner wall of the trough-type bridge base 1; Then, the operator manually passes the end of the cable line body 59 through the third sliding roller rod 38 and extends it to the outer side wall of the top of the support shell 51, so that the bottom of the end of the cable line body 59 close to the end contacts the third sliding roller rod 38, the first sliding roller rod 57 and the second sliding roller rod 53 to form an arc layout, avoiding the cable line body 59 from rubbing against the corner bend of the trough type cable tray base 1 during sliding and wearing. Then, the operator manually rotates the first screw rod 523 rotatably connected to one side wall of the top of the T-shaped support plate 521, so that the first screw rod 523 drives the pressing block 522 threadedly connected to the other side wall in a matching manner through threaded movement to perform linear movement up and down by slidingly connecting to the side wall in the middle position of the top of the T-shaped support plate 521 and the outer wall of the execution end of the second slider 524 on one side wall of the pressing block 522, so that the rubber friction pad 5221 provided on the outer side wall of the bottom of the pressing block 522 is abutted and fixed to the end of the cable line body 59 through linear movement up and down. The rubber friction pad 5221 provides a certain amount of friction and avoids damaging the cable line body 59 due to excessive extrusion. The support shell 51 includes a camera 511 provided at the top of one side adjacent to the support sliding round rod 58. Through the existing image capture information technology, it converts the electrical signal to capture the position information in front of it, facilitating the motor 502 execution end to stop rotating at the turning interface of the cable line body 59. The two sets of sliding traction members 50 have the same structure and operation method. The electric signal is transmitted through the plc controller and triggers the motor 502 execution end. One end of the motor 502 execution end is connected to a first bevel gear 506 and is rotatably supported by the side wall at intervals in the inner cavity of the top of the installation shell 501 through the rotation of the motor 502 execution end. The rotation of the first bevel gear 506 drives the second bevel gear 504 meshed with the bottom of one side to rotate through the round rod embedded at the bottom of the second bevel gear 504 and is rotatably supported by the side wall at the bottom of the inner cavity of the top of the installation shell 501. The round rod embedded at the bottom of the second bevel gear 504 extends and is rotatably connected to the side wall at the bottom of the inner cavity of the movable groove opened at one end of the bottom of the installation shell 501 for support rotation. The rotation of the second bevel gear 504 drives the round rod embedded at the bottom to rotate the sliding anti-slip wheel 505 embedded on the outer side wall at one end of the bottom of the inner cavity of the movable groove opened at one end of the bottom of the installation shell 501, so that the rotation of the two sets of sliding anti-slip wheels 505 drives the cable line body 59 fixed through the above operations to automatically guide and lay towards the other end of the trough type cable tray base 1 on both sides of the inner wall of the trough type cable tray base 1; When approaching the turning point of the interface of the trough cable tray base 1, the position information of the trough cable tray base 1 in front is captured by the camera 511 and converted into an electrical signal to the plc controller. The plc controller then transmits the electrical signal and triggers the execution end of the motor 502 to stop rotating. Its sliding anti-slip wheel 505 includes raised rubber friction lines 5051 provided on the outer side wall, which is convenient for anti-slip during rotation and has a certain damping effect. Even if it is not completely braked, it can provide a certain resistance through continuous friction to make the sliding anti-slip wheel 505 stop braking better. Then, the adjustable auxiliary wheel assembly 3, which can be provided in multiple numbers, is arranged at the turning point of the interface of the trough cable tray base 1. Through the above operation, the distance between the moving clamping plate 36 and the top clamping plate 31 is manually made to be close to each other to clamp the side wall at the turning point of the interface of the trough cable tray base 1. Through the movable round hole opened at the bottom of its rotating support frame 37, the side walls on one side of the top of the rotating support frame 37 are all rotatably connected with the third sliding roller rod 38 to adjust the rotation angle to adapt to the angle at the turning point of the interface of the trough cable tray base 1. Then, by manually rotating, the second fixed cap 35 is made to abut against the outer side wall of the bottom of the rotating support frame 37 for fixation when the adjustment of the rotation angle of the rotating support frame 37 is completed. Make the cable line body 59 contact the third sliding roller rod 38 at the turning point to avoid abrasion when the cable line body 59 slides at the corner and bends. Then, through the above-mentioned fixing method of the cable guiding and guiding component 5, it is re-abutted against the two sides of the inner wall of the trough cable tray base 1, and the cable line body 59 is automatically guided and laid towards the other end of the trough cable tray base 1 in the same way as above. Through the above operation, it is convenient to automatically and conveniently guide and lay the cable line body 59 on the trough cable tray, avoiding the time-consuming and laborious manual dragging or simple pulley-assisted manual dragging of most cables when laying them on the trough cable tray, improving the laying efficiency of the cables and the convenience of the operation.

By manually rotating one set of rotating screws (56), which are supported and rotated by being rotatably connected to the side wall of one set of the support blocks (54) at one end and to the support shell (51) at the other end, the rotation of the rotating screw (56) drives the connecting plate (507) threadedly connected to one side wall to drive the mounting shell (501) to perform a linear movement in the inner cavity of the square through chute (55). The other side wall of the connecting plate (507) is slidably connected to the outer wall of the execution end of the support sliding round rod (58) for support. At the same time, the mounting shell (501) performs a linear movement by the linear movement and is slidably connected to the inner cavity side wall of one end of the support shell (51), so that the sliding anti-slip wheel (505) provided on the mounting shell (501) is adjusted to abut against the side wall of the trough cable tray base (1) through the linear movement. When the spring (5081) provided on one side wall of the first slider (508) is subjected to the force of the sliding anti-slip wheel (505) abutting against the trough cable tray base (1), the first slider (508) provided on the other side wall of the mounting shell (501) drives the spring (5081) to be compressed in the direction where the first slider (508) is slidably connected to the connecting plate (507) on the side wall. The spring (5081) avoids excessive abutting force, which may cause the sliding anti-slip wheel (505) to overly abut against the side wall of the trough cable tray base (1), increasing the rotational friction force of the sliding anti-slip wheel (505), and it also has a certain shock-absorbing effect when the sliding anti-slip wheel (505) rotates. Through the above operation method of one set of sliding traction members (50), the other set of sliding traction members (50) abuts against the side wall of the other side of the trough cable tray base (1), completing the installation of the cable guiding and leading component (5) on both sides of the inner wall of the trough cable tray base (1); Step 3: Then, manually by the operator, the end of the cable line body (59) passes through the third sliding roller rod (38) and extends to the outer side wall of the top of the support shell (51), so that the bottom of the end of the cable line body (59) close to the end contacts the third sliding roller rod (38), the first sliding roller rod (57) and the second sliding roller rod (53) to form an arc layout, avoiding the cable line body (59) from being worn by rubbing against the corner bend of the trough type bridge base (1) during sliding. Then, manually by the operator, rotate the first screw rod (523) rotatably connected to the side wall of one side of the top of the T-shaped support plate (521), so that the first screw rod (523) drives the pressing block (522) threadedly connected to the side wall of the other side and matching with it to perform linear movement up and down through the sliding connection on the side wall of the middle position of the top of the T-shaped support plate (521) and the sliding connection on the outer wall of the execution end of the second slider (524) on one side wall of the pressing block (522), so that the rubber friction pad (5221) provided on the outer side wall of the bottom of the pressing block (522) abuts and fixes on the end of the cable line body (59) through linear movement up and down. The rubber friction pad (5221) provides a certain amount of friction and avoids damaging the cable line body (59) due to excessive extrusion. The support shell (51) includes a camera (511) provided on the top side adjacent to the support sliding round rod (58). Through the existing image capture information technology, it converts the electrical signal to capture the position information in front of it, facilitating the motor (502) execution end to stop rotating at the turning interface of the cable line body (59). The sliding traction member (50) has two sets of the same structure and operation mode. It transmits the electrical signal through the plc controller and triggers the motor (502). One end of the execution end of the motor (502) is connected with a first bevel gear (506). The execution end of the motor (502) is rotatably connected to the side wall of the inner cavity of the top of the installation shell (501) at intervals for supporting rotation. The rotation of the first bevel gear (506) drives the second bevel gear (504) meshed with the bottom of one side to rotate. The second bevel gear (504) is rotatably connected to the bottom side wall of the inner cavity of the top of the installation shell (501) through the round rod embedded at the bottom. The round rod embedded at the bottom of the second bevel gear (504) extends and is rotatably connected to the bottom side wall of the inner cavity of the movable groove opened at one end of the bottom of the installation shell (501) for supporting rotation. The rotation of the second bevel gear (504) drives the round rod embedded at the bottom to rotate the sliding anti-slip wheel (505) embedded on the outer side wall of one end of the bottom of the inner cavity of the movable groove opened at one end of the bottom of the installation shell (501). The rotation of the two sliding anti-slip wheels (505) drives the cable line body (59) fixed through the above operations to be automatically guided and laid towards the other end of the trough type bridge base (1) on both sides of the inner wall of the trough type bridge base (1). Step 4: When approaching the turning point of the interface of the trough cable tray base (1), the position information of the trough cable tray base (1) in front is captured by the camera (511) and converted into an electrical signal to the plc controller. The plc controller then transmits the electrical signal and triggers the execution end of the motor (502) to stop rotating. Its sliding anti-slip wheel (505) includes raised rubber friction lines (5051) provided on the outer side wall, which facilitates anti-slip during rotation and has a certain damping effect. Even if it is not completely braked, it can provide a certain resistance through continuous friction to make the sliding anti-slip wheel (505) stop braking better. Then, the adjustable auxiliary wheel assembly (3) that can be provided in multiple numbers is set at the turning point of the interface of the trough cable tray base (1). Through the above operations, the distance between the moving clamping plate (36) and the top clamping plate (31) is manually adjusted to clamp the side wall at the turning point of the interface of the trough cable tray base (1). Through the movable round hole opened at the bottom of its rotating support frame (37), the third sliding roller rod (38) is rotatably connected to one side wall of the top of the rotating support frame (37) to adjust the rotation angle to adapt to the angle at the turning point of the interface of the trough cable tray base (1). Then, by manually rotating, the second fixed cap (35) is abutted against the outer side wall of the bottom of the rotating support frame (37) for fixation when the rotation angle adjustment of the rotating support frame (37) is completed. The cable line body (59) contacts the third sliding roller rod (38) at the turning point to avoid abrasion when the cable line body (59) slides at the corner during bending. Then, through the above-mentioned fixing method of the cable guiding and guiding component (5), it is re-abutted against both sides of the inner wall of the trough cable tray base (1), and the cable line body (59) is automatically guided to run towards the other end of the trough cable tray base (1) through the same above-mentioned operation. Through the above operations, it is convenient to automatically and conveniently guide and lay the cable line body (59) on the trough cable tray, avoiding the time-consuming and laborious manual dragging or simple pulley-assisted manual dragging of most cables when laying them on the trough cable tray, improving the laying efficiency of the cables and the convenience of the operation.
