Description

Technical Field

[0001] The utility model belongs to the technical field of electric power maintenance equipment, and in particular relates to an electric climbing anti-falling diverter. Background Art

[0002] At present, with the rapid development of science and technology, human demand for electricity is constantly increasing. At the same time, the number of high-altitude power transmission stations is also growing steadily. There are multiple maintenance rails on the transport station body. Each rail is slidably provided with a fall arrester. The fall arrester is provided with an opening and closing buckle. The construction personnel connect the protective clothing to the fall arrester through the opening and closing buckle. The fall arrester slides along the maintenance rail with the climbing speed of the maintenance personnel. The maintenance personnel climb to high altitude and inspect the transport station body.

[0003] According to the application number 202220971135.2, an electric climbing anti-fall diverter is disclosed. It includes a plurality of connecting seats, each of which is fixed at the connection of each two inspection rails, and a middle rail for the anti-fall device to slide is rotatably connected in the connecting seat, and the distance between the end of the middle rail and the end of the inspection rail is not greater than the length of the inspection rail.

[0004] Although the above technical solution can also improve the safety and convenience of the fall arrester, and thus improve the maintenance efficiency of maintenance personnel, when the maintenance personnel move to the junction of the two maintenance rails, they can turn the middle rail to turn. However, there is no connection positioning between the middle rail and the maintenance rail in the above technical solution, which causes the maintenance personnel to turn the middle rail several times to adjust the position so that the maintenance rail and the middle rail can be connected. Long-term continuous rotation of the middle rail may cause wear and fatigue of its internal parts, thereby reducing the service life of the steering gear and may increase the risk of failure. To this end, we provide an electric climbing anti-fall steering gear to solve the above problems. Utility Model Content

The rotating steering limit mechanism can drive the rotating plate to rotate and drive the steering guide rail to rotate. At this time, under the guidance limit of the annular groove, the steering limit mechanism can be rotated to the two ends of the annular groove to stably connect the steering guide rail with other tracks. The steering limit mechanism cooperates with the positioning groove to limit the steering guide rail, thereby preventing the steering limit mechanism from moving at will. This can prevent the anti-fall steering device from rotating multiple times when changing tracks, increasing wear and reducing its service life, and prevent the opening and closing buckles on the protective clothing from slipping off from the two ends of the steering guide rail, thereby improving the safety of the anti-fall steering device.

[0017] (2) The utility model provides an arc-shaped baffle plate. When the rotating plate drives the steering guide rail to rotate, the steering guide rail is always close to the arc-shaped baffle plate. This can reduce the probability of the fall arrester detaching from the steering guide rail and improve the safety of the fall arrester. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 3As shown, the embodiment of the utility model provides an electric climbing anti-falling diverter, including a diverter base 1, the outer surface of the diverter base 1 is provided with two symmetrical annular grooves 2, the outer surface of the diverter base 1 is provided with four circumferential array positioning grooves 3, and the outer surface of the diverter base 1 is provided with a steering limit mechanism 4. The outer surface of the diverter base 1 is fixedly connected with four circumferential array arc baffles 5. In this embodiment, the arc baffles 5 can block the steering guide rail 7, so that when the rotating plate 6 drives the steering guide rail 7 to rotate, the steering guide rail 7 is always close to the arc baffles 5, thereby reducing the probability of the anti-falling device being separated from the steering guide rail 7, and improving the safety of the anti-falling device. The outer surface of the diverter base 1 is rotatably connected with the rotating plate 6, and the outer surface of the rotating plate 6 is fixedly connected with the steering guide rail 7. The outer surface of the diverter base 1 is fixedly connected with four circumferential array connection bases 8, and the inner walls of the four connection bases 8 are all movably connected with external guide rails 11. The outer surfaces of the four connection bases 8 are all provided with three fixing bolts 9, and the outer surfaces of the three fixing bolts 9 are all installed with nuts 10.

[0026] See also Figure 4 As shown, the steering limit mechanism 4 specifically includes a component block 401, the outer surface of the component block 401 is rotatably connected to the outer surface of the steering gear base 1, and the bottom surface of the component block 401 is fixedly connected to two connecting blocks 402, and the outer surface of the connecting block 402 is slidably connected to the inner wall of the annular groove 2. In this embodiment, the annular groove 2 can guide and position the connecting block 402. When the connecting block 402 rotates to one end of the annular groove 2, the rotating plate 6, the steering guide rail 7 and two of the external guide rails 11 are in the same straight line, so that the external guide rail 11 can quickly and stably dock the steering guide rail 7, and the ends of the two connecting blocks 402 away from the bottom surface of the component block 401 are fixedly connected to the outer surface of the rotating plate 6.

[0027] See also Figure 4As shown, the inner wall of the component block 401 is slidably connected with a moving plate 403, and the upper surface of the moving plate 403 is fixedly connected with two springs 404, and one end of the spring 404 away from the upper surface of the moving plate 403 is fixedly connected to the inner wall of the component block 401. In this embodiment, the state of the spring 404 is always in a pushing state, and at this time, the spring 404 can stably push the moving plate 403 to move downward, so that the moving plate 403 can stably push the positioning rod 405 to insert into the inner wall of the positioning groove 3. Two positioning rods 405 are fixedly connected to the bottom surface of the moving plate 403, and the outer surfaces of the positioning rods 405 are slidably connected to the inner wall of the component block 401, and the outer surfaces of the two positioning rods 405 are inserted into the inner wall of the positioning groove 3. In this embodiment, after the positioning rods 405 are inserted into the inner wall of the positioning groove 3, the component block 401 can be limited and the connection block 402 can be limited, so that the rotating plate 6 and the steering guide rail 7 cannot move, thereby ensuring that the steering guide rail 7 is stably docked with the external guide rail 11.

[0028] To further optimize this embodiment, two connecting rods 406 are fixedly connected to the upper surface of the movable plate 403, and the outer surfaces of the connecting rods 406 are slidably connected to the inner wall of the component block 401, and the outer surfaces of the two connecting rods 406 are fixedly connected to connecting plates 407, and the outer surfaces of the connecting plates 407 are fixedly connected to handles 408, and the outer surface of the component block 401 is fixedly connected to handles 409. In this embodiment, the surface of the handle 409 is covered with a rubber sleeve, which can increase the friction of the staff's hands, and the rubber has insulating properties, thereby improving the safety of the staff.

[0029] Working principle: When using this embodiment, first, the fall arrester is transferred to the steering guide rail 7 through one of the external guide rails 11, and then the staff holds the handle 409 and pulls the handle 408 to move upward. At this time, the handle 408 moves upward and drives the connecting plate 407 and the connecting rod 406 to move. At this time, the connecting rod 406 drives the moving plate 403 and the positioning rod 405 to move. The positioning rod 405 moves upward and disengages from the inner wall of the positioning groove 3, thereby releasing the limit on the rotating plate 6. Then, the staff holds the handle 409 to drive the component block 401 to rotate, thereby driving the connecting block 402 to rotate. The movable plate 403 is driven downward by the reverse push of the spring 404. At this time, the movable plate 403 drives the positioning rod 405 to insert into the inner wall of the positioning groove 3, thereby limiting the assembly block 401 and the connecting block 402, thereby limiting the rotating plate 6, and thus limiting the steering guide rail 7. Thus, the steering can be completed after one rotation, thereby reducing friction and increasing the service life, thereby improving the safety of the fall arrester.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
