Description

Technical Field

[0001] This utility model relates to the field of auxiliary tower climbing equipment technology, specifically to a drone-mounted tower climbing anti-fall device. Background Technology

[0002] Traditional tower fall arrestors, such as rigid or flexible rail fall arrestors, require personnel to climb the tower for pre-installation, which presents certain difficulties. Furthermore, installation typically needs to be carried out during a power outage, posing a challenge for most operational power lines. Drones, however, can quickly mount tower fall arrestors to designated locations without disrupting power supply, thus avoiding the safety risks associated with installation during power outages. In addition, the application of drone technology makes the installation of such devices more flexible, adaptable to different types and conditions of towers, further enhancing the safety of high-altitude operations.

[0003] In the existing technology, the sliding pin moves downwards and locks the limit block by relying solely on its own gravity and the gravity of other connected structures. This method is prone to jamming and locking failure, which makes it impossible for the tower fall protection device to be reliably connected to the angle steel. Furthermore, when the tower fall protection device tilts, the sliding pin may fail to lock due to the gravity of the sliding pin and other structures, resulting in the tower fall protection device not being reliably connected to the tower angle steel. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a drone-mounted tower climbing anti-fall device to solve the problem that the existing tower climbing anti-fall device may fail to lock when tilted.

[0005] To achieve the above technical objectives, the technical solution of this utility model is as follows: A drone-mounted tower-climbing anti-fall device, comprising a connecting frame, a mounting rod, a locking rod, a first elastic unit, and a limiting rod, wherein: the mounting rod is rotatably connected to the connecting frame, the upper end of the mounting rod forms a stop portion, the lower end of the mounting rod forms a locking portion, the locking portion and the connecting frame together form a hanging port, and the mounting rod can rotatably switch to open or close the hanging port; the locking rod is slidably connected to the connecting frame, the side of the locking rod extends to form a first limiting portion, and the locking rod is slidably... It has a locking position that abuts against the lower side of the stop portion and a release position that disengages from abutting against the lower side of the stop portion; the first elastic unit is connected to the locking rod to drive the locking rod to move from the release position to the locking position; the limiting rod is slidably connected to the connecting frame, and the sliding direction of the limiting rod is intersected with the sliding direction of the locking rod; the lower end of the limiting rod extends to abut against the stop portion; the side of the limiting rod extends to form a second limiting portion; the limiting rod can slidably switch between abutting against the second limiting portion and disengaging from abutting against the first limiting portion.

[0006] Preferably, a mounting cavity is formed within the connecting frame, and the locking rod, the first elastic unit, and the limiting rod are all disposed within the mounting cavity.

[0007] Preferably, a sliding boss is formed in the mounting cavity, and the locking rod includes a sliding part, which is disposed between the sliding boss and the side of the mounting cavity and can slide along the sliding boss.

[0008] Preferably, the connecting bracket has a first through hole, which communicates with the mounting cavity, and the lower end of the locking rod extends through the first through hole to the outside of the mounting cavity.

[0009] Preferably, the lower end of the locking rod forms a locking hook portion. When the locking rod is in the locking position, the abutment portion is located between the connecting frame and the locking hook portion to restrict the rotation of the abutment portion.

[0010] Preferably, the UAV-mounted tower climbing anti-fall device further includes a second elastic unit, which is connected to the limiting rod to drive the limiting rod to move downward.

[0011] Preferably, the upper end of the connecting frame has a second through hole, and the upper end of the locking rod passes through the second through hole.

[0012] Preferably, the upper end of the locking rod forms a locking ring portion, the upper end of the connecting frame extends to form a connecting block, the locking ring portion and the connecting block together form a hook ring, the locking ring portion can move to open or close the hook ring, when the locking rod is in the locked position the hook ring is open, when the locking rod is in the released position the hook ring is closed.

[0013] Preferably, the first elastic unit is a spring.

[0014] Preferably, the locking rod further includes a slide portion, which is arranged along the sliding direction of the locking rod and is connected to the side of the first limiting portion away from the locking rod.

[0015] Compared with the prior art, the beneficial effects of this utility model include: when the mounting rod rotates, it pushes the limiting rod to move, causing the first limiting part to separate from the second limiting part. Under the action of the first elastic unit, the locking rod moves to the locking position, and the lower end of the locking rod limits the mounting rod, so that the mounting rod can no longer rotate, thereby achieving self-locking and preventing the angle iron from coming out of the hanging hole. Even if the tower fall protection device is tilted, it can prevent its hanging hole from coming out, effectively ensuring the safety of workers. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Please see Figures 1 to 5 This embodiment provides a drone-mounted tower climbing anti-fall device, which includes a connecting frame 1, a mounting rod 2, a locking rod 3, a first elastic unit 4, and a limiting rod 5. The connecting frame 1 is used to connect and install other components, the mounting rod 2 is used to form a hanging port with the connecting frame 1, the locking rod 3 is used to limit the mounting rod 2, the first elastic unit 4 provides elastic force for the locking rod 3 to reset, and the limiting rod 5 is used to restrict the movement of the locking rod 3.

[0019] The mounting rod 2 is rotatably connected to the connecting frame 1. The upper end of the mounting rod 2 forms a stop portion 21, and the lower end forms a locking portion 22. The locking portion 22 and the connecting frame 1 together form a hanging opening. In this embodiment, the lower end of the connecting frame 1 extends downwards, and a pulley is provided at the bottom of the connecting frame 1 for hanging the worker's safety rope. This pulley, together with the locking portion 22, forms the hanging opening, which is used to hang electrical wires or angle irons of electrical equipment. The mounting rod 2 can be rotatably switched to open or close the hanging opening. Specifically, a mounting cavity 11 is formed inside the connecting frame 1, and the locking rod 3, the first elastic unit 4, and the limiting rod 5 are all disposed within the mounting cavity 11. Furthermore, the connecting frame 1 has a first through hole 13, which communicates with the mounting cavity 11. The lower end of the locking rod 3 extends through the first through hole 13 to the outside of the mounting cavity 11. A second through hole 14 is formed at the upper end of the connecting frame 1, and the upper end of the locking rod 3 extends through the second through hole 14.

[0020] The locking rod 3 is slidably connected to the connecting frame 1. The locking rod 3 extends to the side and forms a first limiting part 31. The locking rod 3 is slidably provided with a locking position that abuts against the lower side of the abutment part 21 and a release position that disengages from the abutment part 21. Preferably, a sliding boss 12 is formed in the mounting cavity 11. The locking rod 3 includes a sliding part 35, which is disposed between the sliding boss 12 and the side of the mounting cavity 11 and can slide along the sliding boss 12. Specifically, a locking hook part 32 is formed at the lower end of the locking rod 3. The locking hook part 32 passes through the first through hole 13. When the locking rod 3 is in the locking position, the abutment part 21 is located between the connecting frame 1 and the locking hook part 32 to restrict the rotation of the abutment part 21. The upper end of the locking rod 3 forms a locking ring portion 33, which penetrates the second through hole 14. The upper end of the connecting frame 1 extends to form a connecting block 15. The locking ring portion 33 and the connecting block together form a hook ring. The hook ring is generally used to hang under the drone. When the hook ring is open, it can be separated from the drone. The locking ring portion 33 can move to open or close the hook ring. When the locking rod 3 is in the locked position, the hook ring is open. When the locking rod 3 is in the released position, the hook ring is closed. Preferably, the locking rod 3 also includes a slide portion 34. The slide portion 34 is arranged along the sliding direction of the locking rod 3 and is connected to the side of the first limiting portion 31 away from the locking rod 3. When the locking rod 3 is in the locked position, the slide portion 34 abuts against the second limiting portion 51 to restrict the movement of the limiting rod 5. When the locking rod 3 moves to the released position, the second limiting portion 51 moves with the slide portion 34 and finally moves downward to abut against the first limiting portion 31 due to the action of the second elastic unit 6.

[0021] The first elastic unit 4 is connected to the locking rod 3 to drive the locking rod 3 from the released position to the locked position. Preferably, the first elastic unit 4 is a spring, and using a spring to drive the locking rod 3 makes installation more convenient.

[0022] The limiting rod 5 is slidably connected to the connecting frame 1, and the sliding direction of the limiting rod 5 is intersected with the sliding direction of the locking rod 3. The lower end of the limiting rod 5 extends to abut against the stop part 21. The side of the limiting rod 5 extends to form a second limiting part 51. The limiting rod 5 can slidably switch between abutting against the first limiting part 31 and disengaging from the first limiting part 31. Preferably, the UAV-mounted tower climbing fall protection device also includes a second elastic unit 6, which is connected to the limiting rod 5 to drive the limiting rod 5 to move downward.

[0023] The working principle of the drone-mounted tower fall arrestor provided by this utility model is briefly explained below. The drone moves downwards to attach the tower fall arrestor. The angle iron of the power equipment enters the hanging port, causing the mounting rod 2 to rotate. The connecting frame 1 continues to move downwards. When the stop part 21 completely rests on the angle iron, its own weight causes the mounting rod 2 to continue rotating upwards. The limiting rod 5 is pushed upwards, causing the first limiting part 31 and the second limiting part 51 to disengage. At this time, the mounting rod 2 moves due to the drive of the first elastic unit 4, and the locking hook part 32 hooks the mounting rod 2, preventing it from rotating and thus preventing the hanging port from opening. Therefore, the drone-mounted tower fall arrestor cannot separate from the angle iron, effectively ensuring worker safety. Furthermore, the movement of the locking rod 3 at this time causes the upper hook ring to open, and the hook on the drone automatically separates from the hook ring, achieving drone separation while simultaneously locking itself. When it is necessary to open the hanging port, the worker needs to push the locking rod 3 in the opposite direction to the release position. At this time, the locking hook part 32 separates from the stop part 21, and the hanging rod 2 can be rotated to open the hanging port.

[0024] In summary, the drone-mounted tower fall arrestor provided by this utility model has the following characteristics: when the mounting rod 2 rotates, it pushes the limiting rod 5 to move, causing the first limiting part 31 and the second limiting part 51 to separate. Under the action of the first elastic unit 4, the locking rod 3 moves to the locking position, and the lower end of the locking rod 3 limits the mounting rod 2, preventing the mounting rod 2 from rotating further, thus achieving self-locking and preventing the angle iron from coming out of the hanging wire hole. Even if the tower fall arrestor is tilted, it can prevent its hanging wire hole from coming out, effectively ensuring the safety of workers.

[0025] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
