The setting of the support block 3011 facilitates the contact between the bottom of the first rack 306 and the second rack 307 and the ground. The rotating setting of the support block 3011 ensures that the bottom of the support block 3011 can contact the ground with different degrees of inclination. The setting of the protrusion 3010 can increase the friction between the bottom of the support block 3011 and the ground, preventing the bottom of the support block 3011 from sliding during operation, thereby ensuring the safety and stability of the device during operation.

[0071] As an optimization solution of this embodiment, in order to position and fix the supporting mechanism 7, as shown in FIG. Figure 1 、 Figure 5 As shown, a positioning mechanism 6 is further provided in the middle of the guardrail 9.

The first threaded rod 6017 and the second threaded rod 609 have the same structure, and the thread rotation directions of the first threaded rod 6017 and the second threaded rod 609 are opposite. A first moving block 6016 and a second moving block 6011 are respectively provided on both sides of the center line of the first mounting groove 6018 and the second mounting groove 607. The first moving block 6016 is symmetrically provided on both sides of the center line of the first mounting groove 6018, and the first moving block 6011 is symmetrically provided on both sides of the center line of the first mounting groove 6018. 16 is threadedly connected to the first threaded rod 6017, the second moving block 6011 is symmetrically arranged on both sides of the center line of the second mounting groove 607, and the second moving block 6011 is threadedly connected to the second threaded rod 609. A clamping plate 6013 is fixedly installed on the top of the first moving block 6016 and the second moving block 6011. The first pulley 602 and the second pulley 606 are fixedly installed at the end of the first threaded rod 6017 and the end of the second threaded rod 609 respectively. The two ends of the connecting plate 6019 are respectively connected to the vertical rods 601 and 6010 on the first cross bar 601 and the second cross bar 6010. 08 are connected, the connecting shaft 6020 is rotatably installed on the connecting plate 6019, the third pulley 604 is fixedly installed on the connecting shaft 6020, and the handle 605 is fixedly installed on the end of the connecting shaft 6020. The third pulley 604 drives the first pulley 602 and the second pulley 606 to rotate through the synchronous belt 603. The arrangement of the first threaded rod 6017, the second threaded rod 609 and the first moving block 6016 and the second moving block 6011 can realize the front and rear fixing of the supporting mechanism 7, thereby ensuring the safety and stability of the supporting mechanism 7 during operation.

[0073] Turning the handle 605 drives the third pulley 604 to rotate, and the rotation of the third pulley 604 drives the first pulley 602 and the second pulley 606 to rotate through the synchronous belt 603. The rotation of the first pulley 602 and the second pulley 606 will drive the first threaded rod 6017 and the second threaded rod 609 to rotate. The rotation of the first threaded rod 6017 and the second threaded rod 609 will drive the first moving block 6016 and the second moving block 6011 installed on both sides of the center line of the first threaded rod 6017 and the second threaded rod 609 to move toward the middle of the cross bar at the same time, thereby achieving the purpose of fixing the supporting mechanism 7.

[0074] As an optimization solution of this embodiment, Figure 5 As shown, the positioning mechanism 6 also includes a connecting rod 6015 and a limit block 6014 fixedly installed in the middle of the connecting rod 6015. The two ends of the connecting rod 6015 are respectively connected to the clamping plates 6013 on the first cross bar 601 and the second cross bar 6010. A fixing groove 6012 is opened on the clamping plate 6013. The fixing groove 6012 and the limit block 6014 are both matched with the supporting mechanism 7. The setting of the connecting rod 6015 and the limit block 6014 can serve the purpose of limiting the supporting mechanism 7, preventing the supporting mechanism 7 from moving during operation, and greatly ensuring the stability and safety of the supporting mechanism 7 during operation.

[0075] As an optimization solution of this embodiment, since there is often a certain length loss after the cable is broken (that is, the cable becomes shorter), if the two broken cable ends are not tightened and fixed, after the connection is completed, the weight of the cable will increase the pressure at the cable connection point, which may cause the cable connection point to crack again in severe cases. Figure 7 As shown, it also includes a supporting mechanism 7 installed on the positioning mechanism 6 for supporting and fixing the cable.

[0076] In this embodiment, Figure 7 As shown, the supporting mechanism 7 includes a supporting plate 701, the side walls of the supporting plate 701 cooperate with the fixing groove 6012, and limiting grooves 702 are opened on both sides of the middle part of the supporting plate 701, and the limiting grooves 702 cooperate with the limiting blocks 6014. The supporting mechanism 7 is used to support the broken cable to prevent the connection of the completed cable from breaking again due to the weight of the cable, thereby greatly ensuring the wiring quality of the cable.

[0077] In this embodiment, Figure 7 、 Figure 8As shown, the supporting mechanism 7 also includes an adjusting block 704, a strip groove 706 is opened at both ends of the supporting plate 701, and the adjusting block 704 is arranged in the strip groove 706, and a fixing hole 7015 is opened on the side wall of the strip groove 706. A third threaded rod 703 is set in one of the fixing holes 7015 on the side wall of the strip groove 706, and a second guide rod 705 is set in the other fixing hole 7015. The adjusting blocks 704 are symmetrically arranged at both ends of the center line of the supporting plate 701, one end of the adjusting block 704 is threadedly connected to the third threaded rod 703, and the other end of the adjusting block 704 is threadedly connected to the second The guide rod 705 is slidably connected, and a clamping piece 707 for clamping and fixing the cable is provided at the bottom of the adjusting block 704. When one end of the broken cable passes through the clamping piece 707 under the action of the first rope 409 or the second rope 407, the clamping piece 707 fixes the cable. When the wiring is completed, if the cable bends downward to a large extent under the action of its own weight, the adjusting block 704 can be driven to move toward a position close to the middle of the supporting plate 701 by rotating the third threaded rod 703, thereby tightening the cable again to ensure that the cable is always in a stable state after the wiring is completed.

[0078] In this embodiment, the cooperation between the fixing groove 6012 and the support plate 701 can limit the up and down movement of the support plate 701 during the working process, and the cooperation between the limiting groove 702 and the limiting block 6014 can limit the forward and backward movement of the support plate 701 during the working process, ensuring that the support plate 701 is always in a stable state during the working process, thereby improving the wiring efficiency and wiring quality at the cable break.

[0079] As an optimization solution of this embodiment, Figure 8 As shown, the clamping member 707 includes a clamping block 709, a screw 7011, a handle 7010, a support plate 7012 and a second side plate 708 fixedly installed at both ends of the support plate 7012, the second side plate 708 is fixedly installed on the adjusting block 704, the screw 7011 is threadedly installed on the support plate 7012, the clamping block 709 is arranged between the second side plates 708 on both sides of the center line of the support plate 7012, and the clamping block 709 is rotatably connected to the screw 7011, the handle 7010 is fixedly installed at the end of the screw 7011, the clamping block 709 and the adjusting block 704 cooperate with each other to fix the cable, and the clamping member 707 is used to fix the cable to prevent the cable from being torn at the connection of the cable due to its own weight, thereby greatly ensuring the wiring quality of the cable.

[0080] The handle 7010 is rotated to drive the clamping block 709 to move toward the side close to the adjusting block 704, and the purpose of fixing the cable is achieved under the cooperation of the clamping block 709 and the adjusting block 704.

[0081] As an optimization solution of this embodiment, Figure 9As shown, a groove 7013 is provided in the middle of the clamping block 709, and V-shaped grooves 7014 are opened on the two side walls of the groove 7013. The groove 7013 cooperates with the adjustment block 704. The setting of the V-shaped groove 7014 can clamp cables of different sizes, thereby improving the use scenarios of the device.

[0082] When the handle 7010 is rotated to drive the clamping block 709 close to the adjusting block 704, the groove 7013 on the clamping block 709 will press the cable onto the adjusting block 704, and the V-grooves 7014 on both sides of the groove 7013 will drive the cable to continue moving, so that the cable forms a bend on both sides of the adjusting block 704. The formation of the bend can increase the friction between the cable, the clamping block 709 and the adjusting block 704, thereby improving the clamping efficiency and the clamping effect.

[0083] As an optimization solution of this embodiment, in order to prevent the cable head from falling off from the top plate 8 when the broken cable head is tightened, thereby affecting the pulling efficiency and pulling quality of the cable head, as shown in FIG. Figure 1 As shown, guide members 5 for guiding the cables are provided at both ends of the guardrail 9.

[0084] In this embodiment, Figure 6 As shown, the guide member 5 includes a mounting plate 501, a push rod 5012, a push plate 506 and a lifting block 509 arranged on both sides of the center line of the top plate 8.

The guide member 5 is used to guide the cable to prevent the cable from falling off from the top plate 8 when the end of the broken cable is pulled, affecting the lifting quality of the cable, thereby ensuring the wiring efficiency and wiring quality of the cable.

[0085] In this embodiment, the setting of the guide rod 504, the spring 505 and the slider 502 can always push the push plate 506 downward, ensuring that the push plates 506 on both sides can clamp the cable, thereby achieving the purpose of guiding the cable and ensuring that the cable is always on the support plate 701 during the pulling process. It can prevent the cable from falling off the support plate 701 during the lifting process, thereby ensuring the safety and stability of the cable.

[0086] The spring 505 can always provide downward pressure for the slider 502, ensuring that the push rod 5012 always pushes the push plate 506 outward, ensuring that the lifting block 509 on the push plate 506 always restricts the cable that needs to be lifted, and ensuring the safety of the cable during the lifting process.

[0087] In order to prevent the cable from being worn or damaged by friction between the cable and the lifting block 509 when the cable is lifted too quickly or the middle of the cable sinks too much during the process of pulling and lifting the cable, Figure 6 As shown, a slide groove 507 is provided on the side wall of the push plate 506, and a third side plate 5010 is provided on both sides of the lifting block 509. A protrusion 508 is installed on the third side plate 5010, and the protrusion 508 slides in cooperation with the slide groove 507. In the process of pulling the cable up and down, the lifting block 509 will move up and down along the slide groove 507 on the push plate 506, thereby reducing the bending angle of the cable during the lifting process, ensuring the safety and stability of the cable during wiring and lifting.

[0088] In this embodiment, Figure 6 As shown, a shift rod 5011 is provided at the bottom of the left lifting block 509 and the top of the right lifting block 509, and an avoidance groove (not shown in the figure) is opened at the top of the left lifting block 509 and the bottom of the right lifting block 509.
