DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0025] Embodiment: please refer to Figs. 1-4The application provides a power transmission line steel pipe pole ladder cage anti-climbing plugging device, which comprises a plugging net body 1 arranged in a net structure. In the embodiment, the peripheral net edge structure of the plugging net body 1 is made of steel pipes welded together. The size of the peripheral net edge structure can be customized according to actual conditions, but it needs to meet the requirement of plugging the inlet of the power transmission line steel pipe pole ladder cage. The internal grid structure of the plugging net body 1 is made of steel pipes arranged horizontally and steel pipes arranged vertically which are cross-welded together. The size of the grid formed by the cross of the steel pipes arranged horizontally and the steel pipes arranged vertically should meet the requirement that a person cannot pass through the grid to ensure the plugging effect of the plugging net body 1. The bottom of the plugging net body 1 is provided with a connecting assembly 2 for movably connecting the plugging net body 1 to the power transmission line steel pipe pole ladder. The plugging net body 1 is also provided with a fixing assembly for fixedly connecting the plugging net body 1 to the power transmission line steel pipe pole ladder cage. Through the arrangement of the connecting assembly 2 and the fixing assembly, the connecting assembly 2 can movably connect the plugging net body 1 to the power transmission line steel pipe pole ladder. Then, the staff rotates the plugging net body 1 to cover the inlet of the power transmission line steel pipe pole ladder cage, and then uses the fixing assembly to fix the plugging net body 1, so that the plugging work is completed. Non-staff cannot climb into the power transmission line steel pipe pole ladder without using cutting tools or unlocking tools. When the staff needs to climb into the power transmission line steel pipe pole ladder, the fixing assembly is released from the plugging net body 1 by using the dismounting assembly matched with the fixing assembly, and then the plugging net body 1 is moved away from the inlet of the power transmission line steel pipe pole ladder cage, so that the staff can climb into the power transmission line steel pipe pole ladder. Meanwhile, the staff can use the steel pipes arranged horizontally in the plugging net body 1 as stepping points when climbing into the power transmission line steel pipe pole ladder, so that the staff can more easily climb into the power transmission line steel pipe pole ladder.

[0026] The traditional power transmission line steel pipe pole ladder is mainly divided into flat ladder type and tubular ladder type. In order to be suitable for the flat ladder type and the tubular ladder type, the connecting assembly 2 comprises a first connecting piece and a second connecting piece. The first connecting piece comprises two first clamping plates 201 symmetrically arranged at the bottom of the plugging net body 1. The top of the two first clamping plates 201 is welded together with the bottom of the plugging net body 1, and the two first clamping plates 201 are parallel to the plugging net body 1, so as to ensure the plugging effect of the plugging net body 1 after subsequent installation. The middle part of the two first clamping plates 201 is provided with a first arc-shaped part 202. The two first clamping plates 201 are detachably connected with a second clamping plate 203 through a first fastener. One first clamping plate 201 is connected with one second clamping plate 203. The middle part of the two second clamping plates 203 is provided with a second arc-shaped part 204. The second arc-shaped part 204 of the two second clamping plates 203 and the first arc-shaped part 202 of the corresponding first clamping plate 201 are mutually spliced to form a first installation space 205.

[0027] The second connecting piece comprises a rotating shaft 206 arranged between the two first clamping plates 201, both ends of the rotating shaft 206 are movably connected in the corresponding first mounting space 205, and, in order to prevent both ends of the rotating shaft 206 from falling out of the corresponding first mounting space 205, a limiting block 211 with an area larger than that of the first mounting space 205 is symmetrically arranged on the rotating shaft 206, and the arrangement of the two limiting blocks 211 satisfies that, when both ends of the rotating shaft 206 are connected in the corresponding first mounting space 205, the two limiting blocks 211 will touch the plate walls of the corresponding first clamping plate 201 and the second clamping plate 203 together, thereby preventing the rotating shaft 206 from moving left and right, so as to ensure that both ends of the rotating shaft 206 will not fall out of the corresponding first mounting space 205; the rotating shaft 206 is fixedly connected with a first connecting plate 207, the first connecting plate 207 is arranged in an "L" shape structure, so as to adapt to the structure of the tubular ladder during the later installation process, the vertical plate section of the first connecting plate 207 is fixedly connected to the shaft wall of the rotating shaft 206, and the horizontal plate section of the first connecting plate 207 is detachably connected with a second connecting plate 208 through the arrangement of a second fastener, the second connecting plate 208 is arranged on the plate wall of the horizontal plate section of the first connecting plate 207 away from the rotating shaft 206, and the middle part of the second connecting plate 208 is provided with a third arc-shaped part 209, which cooperates with the horizontal plate section of the first connecting plate 207 to form a second mounting space 210.

[0028] Through the arrangement of the first mounting space 205 and the second mounting space 210, when the anti-climbing plugging device needs to be installed on the flat ladder, first, the second connecting piece is separated from the first connecting piece, and the specific separation method is: by detaching the first fastener from the two first clamping plates 201 and the second clamping plate 203, the two first clamping plates 201 are separated from the corresponding second clamping plate 203, and then both ends of the rotating shaft 206 are taken out of the corresponding first mounting space 205, so that the second connecting piece is separated from the first connecting piece; then, the two first clamping plates 201 and the second clamping plate 203 are clamped on a first ladder of the flat ladder, so that the first mounting space 205 is formed between the two first clamping plates 201 and the corresponding second clamping plate 203, and the first ladder is in the first mounting space 205, and then the first clamping plate 201 and the second clamping plate 203 are connected together by using the first fastener, so that the anti-climbing plugging device is installed on the flat ladder; in order to ensure the use effect of the anti-climbing plugging device, the shape of the first mounting space 205 should satisfy that, after installation, the anti-climbing plugging device cooperates with the corresponding ladder in the first mounting space 205, and the plugging net body 1 in the anti-climbing plugging device can rotate around the ladder in the first mounting space 205, so that the plugging net body 1 can control the opening and closing state of the entrance of the flat ladder;

[0029] When the anti-climbing plugging device needs to be installed on the tubular ladder, the first connecting member and the second connecting member do not need to be separated, the first connecting plate 207 and the second connecting plate 208 are separated by removing the second fastener from the first connecting plate 207 and the second connecting plate 208, then the first connecting plate 207 and the second connecting plate 208 are clamped on the tubular ladder, so that the second installation space 210 is formed between the first connecting plate 207 and the second connecting plate 208, and the tubular ladder is in the second installation space 210, then the first connecting plate 207 and the second connecting plate 208 are connected together by using the second fastener, so that the anti-climbing plugging device is installed on the tubular ladder. In order to ensure the use effect of the anti-climbing plugging device, the shape of the second installation space 210 should meet the following conditions: after installation, the anti-climbing plugging device cooperates with the tubular ladder through the second installation space 210, the anti-climbing plugging device can be fixed on the tubular ladder, and the plugging net body 1 in the anti-climbing plugging device can rotate around the rotating shaft 206 through the movable connection of the first installation space 205 and the rotating shaft 206, so as to control the opening and closing state of the cage inlet of the tubular ladder.

[0030] In order to facilitate the disassembly and assembly of the staff, the first fastener includes a first connecting screw 3, and first installation holes are formed in the two first clamping plates 201 and the two second clamping plates 203 for the rod part of the first connecting screw 3 to pass through. The rod part of the first connecting screw 3 passes through the first installation holes in sequence and then passes through the second clamping plates 203 and the first clamping plates 201, and a first locking nut 4 is locked on the rod part of the first connecting screw 3. When the first fastener connects the first clamping plates 201 and the second clamping plates 203, the first locking nut 4 is locked on the rod part of the first connecting screw 3 after the rod part passes through the first clamping plates 201 and the second clamping plates 203, so that the first clamping plates 201 and the second clamping plates 203 are connected together. The second fastener includes a second connecting screw 5, and second installation holes are formed in the transverse plate section of the first connecting plate 207 and the second connecting plate 208 for the rod part of the second connecting screw 5 to pass through. The rod part of the second connecting screw 5 passes through the second installation holes in sequence and then passes through the transverse plate section of the first connecting plate 207 and the second connecting plate 208, and a second locking nut 6 is locked on the rod part of the second connecting screw 5. When the second fastener connects the transverse plate section of the first connecting plate 207 and the second connecting plate 208, the second locking nut 6 is locked on the rod part of the second connecting screw 5 after the rod part passes through the transverse plate section of the first connecting plate 207 and the second connecting plate 208, so that the transverse plate section of the first connecting plate 207 and the second connecting plate 208 are connected together. The overall disassembly and assembly process is simple and convenient.

[0031] In order to facilitate the dismounting work of the staff, the fixing assembly comprises a sleeve 7 movably sleeved on the blocking net body 1, and a padlock 8 is connected to the sleeve 7. The movably arranged sleeve 7 enables the padlock 8 to move on the blocking net body 1, so as to facilitate the later binding work of the staff. The padlock 8 is further locked with a lock 9. When the blocking net body 1 is connected to the power transmission line steel pipe pole ladder through the first connecting piece or the second connecting piece, the blocking net body 1 is rotated to cover the entrance of the protective cage of the power transmission line steel pipe pole ladder, and then the padlock 8 is bound to the protective cage of the power transmission line steel pipe pole ladder. Finally, the lock 9 is used to lock the padlock 8 and the protective cage of the power transmission line steel pipe pole ladder together, so as to fix the blocking net body 1 on the entrance of the protective cage of the power transmission line steel pipe pole ladder, thereby forming a blockage, so that non-staff cannot climb into the power transmission line steel pipe pole ladder without using cutting tools or unlocking tools. When the staff needs to climb in, the lock 9 is opened by using the key matched with the lock 9, and then the padlock 8 is dismounted from the protective cage of the power transmission line steel pipe pole ladder, so that the blocking net body 1 loses the fixation on one side and can be rotated. Then, the blocking net body 1 is turned away from the entrance of the protective cage of the power transmission line steel pipe pole ladder, and the staff can climb into the power transmission line steel pipe pole ladder. It is simple and convenient to use.

[0032] The above is only a typical example of the present application, in addition to which the present application can have other various specific embodiments, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of the present application.
