Description

Technical Field

[0001] This utility model relates to the field of power transmission line fall prevention technology, specifically to a novel high-voltage power transmission line fall prevention device. Background Technology

[0002] Electricity is transmitted through power transmission lines. Since power is carried by electricity, power transmission lines are usually erected high on poles or towers. The erected power transmission lines are affected by their own weight or external factors such as wind and snow pressure. Therefore, when installing cables, anti-fall devices are needed to suspend the power transmission lines on the load-bearing wires or connecting plates on the poles.

[0003] A search revealed that Chinese Patent Publication No. CN222563482U discloses a novel high-voltage transmission line fall protection device, comprising: a left clamp and a right clamp, both of which are arc-shaped of equal size. One end of the left clamp is rotatably connected to the right clamp via a hinge, and the other end is detachably connected to the right clamp via a pin. The left clamp is provided with an extension, and the extension is equipped with a clamping block that can be adjusted downwards via an adjusting screw. A U-shaped hanging ring is mounted on the adjusting screw.

[0004] Over time, utility poles may tilt slightly due to foundation settlement, soil loosening, or other reasons. Workers need to adjust the cable lengths between poles to rebalance the tension on the poles and ensure stable and safe power transmission. This device uses a screw to fix the cable in place, and then hangs the device and cable on the pole. When maintenance, adjustment, or replacement of the cable is required, the device must be removed from the connecting plate before the screw can be rotated to release the cable, causing considerable inconvenience for power line maintenance. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a new type of high-voltage transmission line anti-fall device, which can effectively solve the problem of inconvenient cable adjustment and installation / disassembly between power poles in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a novel high-voltage transmission line fall protection device, including a hook, with limit blocks fixedly connected to both the front and rear sides of the bottom of the hook, mounting plates provided on both the left and right sides of the hook, a pressure plate fixedly connected between the two mounting plates, and sliders fixedly connected between both ends of the two mounting plates.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: Refer to Figures 1 to 3 A novel high-voltage transmission line fall protection device includes a hook 1, with limit blocks 2 fixedly connected to the front and rear sides of the bottom of the hook 1. Mounting plates 3 are provided on the left and right sides of the hook 1. A pressure plate 4 is fixedly connected between the two mounting plates 3. A slider 5 is fixedly connected between the two ends of the two mounting plates 3. One side of each slider 5 is in sliding contact with the two limit blocks 2. A limit plate 6 is provided at the top of one end of each mounting plate 3. An installation groove 7 is opened on one side of the limit plate 6. A toothed plate 8 is slidably connected inside the installation groove 7.

[0024] Each of the two mounting plates 3 has a limiting rod 9 at one bottom. The top of each limiting rod 9 passes through the two mounting plates 3 and is slidably connected to the two mounting plates 3. The top of each limiting rod 9 is fixedly connected to the limiting plate 6.

[0025] A pull rod 10 is fixedly connected to one side of the toothed plate 8. The pull rod 10 passes through the limiting plate 6 and slides in contact with it. A spring 11 is sleeved on the outside of the pull rod 10. The spring 11 is fixedly connected between the toothed plate 8 and the mounting groove 7. A toothed groove 12 adapted to the toothed plate 8 is opened on one side of the hook 1. The teeth of the toothed groove 12 are inclined downwards. When the teeth of the toothed plate 8 are engaged with the toothed groove 12, the toothed plate 8 can only move downwards and cannot move upwards under the action of the toothed groove 12. This allows the pressure plate 4 to quickly fit with the cable when fixing the cable, and the device can fix cables of different sizes while improving the cable fixing efficiency.

[0026] Each of the two mounting plates 3 has a push rod 13 at one top. The push rod 13 passes through the limiting plate 6 and is slidably connected to the limiting plate 6. A connecting rod 14 is fixedly connected between one end of the two push rods 13. A threaded rod 15 is fixedly connected to one side of the limiting plate 6. The connecting rod 14 has a through hole that matches the threaded rod 15. A nut 16 is threaded to the outer side of one end of the threaded rod 15. During operation, by rotating the nut 16, the push rod 13 is moved toward the arc surface at the top of the mounting plate 3, thereby pushing the pressure plate 4 to move further downward, making the pressure plate 4 more secure in fixing the cable.

[0027] An L-shaped plate 17 is fixedly connected to the top of the inner side of the hook 1. The bottom of the pressure plate 4 is provided with a slot that matches the L-shaped plate 17. Before installing the cable, the pressure plate 4 can be placed on top of the L-shaped plate 17, which makes it convenient for workers to place the cable inside the hook 1.

[0028] The top of the hook 1 is fixedly connected to a fixing plate 18, and the top of the fixing plate 18 is rotatably connected to a ring 19. A U-shaped hanging ring 20 is provided inside the ring 19. Bolt holes are opened at both ends of the top of the U-shaped hanging ring 20, and a bolt 21 is installed between the two bolt holes. During operation, the device can be fixed to the connecting plate of the utility pole in advance by bolts 21.

[0029] The working principle of this utility model is as follows:

[0030] During operation, first fix the U-shaped hanging ring 20 to the connecting plate of the utility pole, then hang the power transmission cable inside the hook 1. The worker can then remove the pressure plate 4 from the top of the L-shaped plate 17. Next, place the two sliders 5 on the outside of the two limiting blocks 2. When the two sliders 5 are on the outside of the two limiting blocks 2, the toothed plate 8 is in contact with the toothed groove 12 under the elastic force of the spring 11, and the sliders 5 slide in contact with the limiting blocks 2. At this point, the worker can directly push the pressure plate 4 horizontally downwards to press down the cable. During movement, the limiting plate 6 moves downward via the limiting rod 9. After the pressure plate 4 presses the cable, it can push the limiting plate 6 to continue moving downward so that the bottom of the limiting plate 6 fits against the mounting plate 3. The toothed plate 8 inside the limiting plate 6 limits the limiting plate 6 through the toothed groove 12 to prevent the limiting plate 6 from moving upward. Then, the worker can rotate the nut 16 so that the threaded rod 15 drives the push rod 13 to push towards the mounting plate 3. Under the action of its arc surface, the mounting plate 3 further drives the pressure plate 4 to press down, thereby fixing and securing the cable.

[0031] When it is necessary to disassemble the cable, the worker can pull the lever 10 to move the toothed plate 8 away from the toothed groove 12, thereby releasing the limit plate 6 from limiting the pressure plate 4. At this time, the pressure plate 4 can be moved upward and placed on top of the L-shaped plate 17, so as to quickly disassemble the fixed cable.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
