Description

Technical Field

[0001] The invention belongs to the technical field of UHV transmission line construction, and particularly relates to a climbing structure for UHV transmission line construction. Background Art

[0002] During the construction of UHV transmission lines, it is often necessary to climb on the poles. However, on existing poles, to prevent unauthorized persons from climbing, the height of the first step of the pole from the ground is relatively high, which causes great inconvenience to the climbing of construction workers. Climbing tools are needed. Existing climbing tools often only adopt ordinary ladder structures and directly use ordinary stepladders. However, when existing stepladders are used in mountainous areas, they cannot be fixed firmly, and safety hazards are easily caused during the climbing process. Summary of the Invention

[0003] The purpose of the invention is to provide a climbing structure for UHV transmission line construction to solve the problem that the existing ladder is not easy to fix. The structure of the invention is simple, which is convenient for quickly fixing the climbing structure and reducing safety hazards during the climbing process.

[0004] To achieve the above purpose, the invention adopts the following technical scheme:

[0005] A climbing structure for UHV transmission line construction includes a bottom plate. Triangular grab blocks are provided at the bottom end of the bottom plate. A fixed support rod is provided at the top end of the bottom plate. An adjusting rod is provided at the top end of the fixed support rod. Through rods are provided on the left and right sides of the fixed support rod. Fixed connection grooves matching the diameter of the through rods are provided on the lower sides of the left and right sides of the adjusting rod. A number of groups of cross plates are provided on the left and right sides of the adjusting rod. A rotating shaft is provided at the connection between the cross plate and the adjusting rod. A rotating diagonal support rod is provided at the bottom end of the cross plate. A connecting rotating shaft is provided at the connection between the outer side of the rotating diagonal support rod and the cross plate. A telescopic adjusting rod is provided inside the rotating diagonal support rod. A fixed through rod is provided at the bottom end of the rotating diagonal support rod. A fixed groove matching the diameter of the fixed through rod is provided at the bottom end of the telescopic adjusting rod. An arc-shaped clamping block is provided inside the telescopic adjusting rod. A total of six groups of arc-shaped clamping grooves matching the arc-shaped clamping blocks are provided on the left and right sides of the adjusting rod. A top connection block is provided at the top end of the adjusting rod.

[0006] Furthermore, an induction block is provided between the top end of the adjusting rod and the bottom of the top connection block. Two fixed rods are provided at the top end inside the cavity of the top connection block. A rotating plate is provided at the bottom end of the fixed rod. An adjusting rotating shaft is provided at the connection between the rotating plate and the fixed rod. A return spring is provided between the inner side of the top end of the rotating plate and the top end inside the cavity of the top connection block. A reaction rod is provided at the outer side of the bottom end of the rotating plate. An arc-shaped clamping groove is provided at the bottom end of the reaction rod.

[0007] Further, the return spring is located between two sets of fixed rods.

[0008] Further, the bottom end of the reaction rod extends out of the inner cavity of the top connecting block.

[0009] Further, the bottom end of the top connecting block is provided with an opening matching the diameter of the induction block, and the induction block extends into the inner cavity of the top connecting block through the opening.

[0010] Further, several sets of openings matching the diameter of the through rod are provided on the left and right side plates of the fixed support rod.

[0011] Further, an opening matching the diameter of the fixed through rod is provided on the bottom plate of the rotating diagonal support rod, and the fixed through rod extends into the inner cavity of the rotating diagonal support rod through the opening and is connected to the telescopic adjusting rod.

[0012] Further, a wavy groove is provided at the top end of the cross plate.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] The present invention adopts a rotating diagonal support rod. The connection rotating shaft rotates to drive the rotating diagonal support rod, and then the telescopic adjusting rod is pulled out of the inner cavity of the rotating diagonal support rod, so that the arc-shaped clamping block is clamped into the arc-shaped clamping groove, and the fixed through rod is inserted into the fixed groove, which is convenient for supporting the cross plate and avoiding the cross plate from breaking.

[0015] The present invention adopts a return spring. When it is necessary to connect to the tower, the top connecting block contacts the tower. When the end of the induction block outside the top connecting block contacts the tower, it moves into the inner cavity of the tower, causing the inner sides of the two rotating plates to move upward to compress the return spring, causing the rotating plates to rotate through the adjusting rotating shaft, causing the reaction rod to push downward, and clamping the tower through the arc-shaped clamping groove, then climbing can be carried out; when it is necessary to disengage from the tower, push downward to drive the rotating plates to rotate in the reverse direction, release the two sets of arc-shaped clamping grooves, and then the climbing structure can be removed.

[0016] Further, several sets of openings matching the diameter of the through rod are provided on the left and right side plates of the fixed support rod, which can conveniently adjust the length of the adjusting rod extending into the inner cavity of the fixed support rod.

[0017] Further, by providing a wavy groove at the top end of the cross plate, it is convenient for fingers to be located in the groove during the climbing process, increasing the friction force. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Please refer to Figure 1 , the present invention provides a technical solution: a climbing structure for UHV transmission line construction, including a bottom plate 1. A triangular grabbing block 2 is provided at the bottom end of the bottom plate 1. The connection degree between the bottom plate 1 and the ground can be increased through the triangular grabbing block 2, avoiding slippage caused by insufficient connection degree when the bottom plate 1 contacts the ground. A fixed support rod 3 is provided at the top end of the bottom plate 1. An adjusting rod 4 is provided at the top end of the fixed support rod 3. An opening matching the diameter opening of the adjusting rod 4 is provided at the top end of the fixed support rod 3. The adjusting rod 4 extends into the inner cavity of the fixed support rod 3 through the opening, facilitating the adjustment of the length of the adjusting rod 4 extending into the inner cavity of the fixed support rod 3. Through rods 5 are provided on the left and right sides of the fixed support rod 3. Fixed connection grooves 6 matching the diameter of the through rods 5 are provided on the left and right sides of the adjusting rod 4. Six groups of cross plates 7 are provided on the left and right sides of the adjusting rod 4. A rotating shaft 8 is provided at the connection between the cross plate 7 and the adjusting rod 4. A rotating inclined support rod 9 is provided at the bottom end of the cross plate 7.

A telescopic adjusting rod 11 is provided inside the rotating inclined support rod 9. A fixed through rod 12 is provided at the bottom end of the rotating inclined support rod 9. A fixed groove 13 matching the diameter of the fixed through rod 12 is provided at the bottom end of the telescopic adjusting rod 11. An arc-shaped clamping block 15 is provided inside the telescopic adjusting rod 11. Six groups of arc-shaped clamping grooves 14 matching the arc-shaped clamping block 15 are provided on the left and right sides of the adjusting rod 4. By rotating through the connecting rotating shaft 10 to drive the rotating inclined support rod 9, and then pulling out the telescopic adjusting rod 11 from the inner cavity of the rotating inclined support rod 9, the arc-shaped clamping block 15 is clamped into the arc-shaped clamping groove 14, and the fixed through rod 12 is inserted into the fixed groove 13 to fix the telescopic adjusting rod 11, avoiding the cross plate 7 rotating through the rotating shaft 8 during the climbing process. A top connecting block 16 is provided at the top end of the adjusting rod 4.

[0023] Please refer to Figure 2, at the bottom of the top connection block 16, there is an induction block 17. At the top end of the inner cavity of the top connection block 16, there are two groups of fixing rods 18. At the bottom ends of the two groups of fixing rods 18, there are rotating plates 19. At the connection between the rotating plate 19 and the fixing rod 18, there is an adjusting rotating shaft 20. At the inner top end of the rotating plate 19, there is a return spring 23. At the outer bottom end of the rotating plate 19, there is a reaction rod 21. At the bottom end of the reaction rod 21, there is an arc-shaped clamping groove 22. When the end of the induction block 17 outside the top connection block 16 touches the tower pole and moves into the inner cavity of the tower pole, the inner side of the rotating plate 19 moves upward, causing the rotating plate 19 to rotate through the adjusting rotating shaft 20, pushing the reaction rod 21 downward, and clamping the tower pole through the arc-shaped clamping groove 22. And the return spring 23 can, when it is necessary to disengage from the tower pole, push downward (the top end of the return spring 23 is fixedly connected to the bottom end of the inner cavity of the top connection block 19. When being squeezed, it moves upward and contracts. When the squeezing disappears, it can only move downward. That is, one end of the return spring 23 is fixedly locked and can only perform telescopic movement through the other end), driving the rotating plate 19 to rotate in the reverse direction and releasing the two arc-shaped clamping grooves 22.

[0024] Please refer to Figure 1 , on the left and right side plates of the fixed support rod 3, there are four groups of openings that match the diameter of the through rod 4, which is convenient for inserting the through rod 5 into the openings at different heights according to the length of the adjusting rod 4 extending into the inner cavity of the fixed support rod 3, facilitating the fixation of the adjusting rod 4.

[0025] Please refer to Figure 1 , on the bottom plate of the rotating diagonal support rod 9, there is an opening that matches the diameter of the fixed through rod 12. The fixed through rod 12 extends into the inner cavity of the rotating diagonal support rod 9 through the opening and is connected to the telescopic adjusting rod 11, which is convenient for fixing the position of the telescopic adjusting rod 11 by inserting the fixed through rod 12 into the fixed groove 13.

[0026] Please refer to Figure 2 , at the bottom of the top connection block 16, there is an opening that matches the diameter of the induction block 17. The induction block 17 extends into the inner cavity of the top connection block 16 through the opening, which is convenient for controlling the rotation of the rotating plate 19 through the induction block 17.

[0027] Please refer to Figure 1 , at the top end of the horizontal plate 7, there are wave pattern grooves, which is convenient for the fingers to be located in the grooves during the climbing process to increase the friction force.

[0028] Working principle: When in use, first place the bottom plate 1 at the required climbing position of the pole tower. Then, according to the distance between the first step of the pole tower and the ground, adjust the length of the adjusting rod 4 extending into the inner cavity of the fixed support rod 3. Insert the through rod 5 into the fixed connection groove 6 to fix the adjusting rod 4. Then, rotate the cross plate 7 through the rotating shaft 8 to a 90-degree angle with the adjusting rod 4. Next, rotate the rotating inclined support rod 9 through the connecting rotating shaft 10, pull out the telescopic adjusting rod 11 from the inner cavity of the rotating inclined support rod 9, snap the arc-shaped clamping block 15 into the arc-shaped clamping groove 14, and insert the fixed through rod 12 into the inner cavity of the rotating inclined support rod 9 and connect it to the fixed groove 13 to fix the telescopic adjusting rod 11. Then, make the top connecting block 16 contact the pole tower. When the end of the induction block 17 outside the top connecting block 16 contacts the pole tower and then moves into the inner cavity of the pole tower, the inner side of the rotating plate 19 moves upward, causing the rotating plate 19 to rotate through the adjusting rotating shaft 20, pushing the reaction rod 21 downward, and clamping the pole tower through the arc-shaped clamping groove 22, and then climbing can be carried out.
