Technical Field
[0001] The utility model relates to the technical field of electric power communication, in particular to an anti-falling device for an electric power communication pole tower. Background Art
[0002] Power communication towers are bridges of electricity, allowing electricity to be transported to various places. Common power communication towers include wooden poles, concrete poles and metal towers. They are of different heights, standing in plains and mountains, and are scattered around people. In real life, power communication towers often need to be repaired and inspected. When repairing and inspecting power communication towers, maintenance personnel are required to perform high-altitude operations. Since high-altitude operations are relatively dangerous, anti-fall devices are essential accessories for maintenance personnel when climbing.
[0003] Traditional fall prevention devices generally require workers to wear a safety rope on their bodies. When climbing a pole tower, they need to hook the connecting hook on the safety rope onto the railing of the pole tower. This requires the workers to remove the connecting hook from the previous railing after moving a certain distance, and then hook the hook onto the railing next to them. When the workers are removing the hook and then re-hooking it, their bodies are out of the pole tower. If the workers are not careful or miss a step at this time, they will fall from a height, which poses a great safety hazard.
[0004] For example, an anti-fall device for a power communication pole tower with publication number CN219974361U, in which a worker wears a safety belt, then hangs the hook on the safety belt on the hanging ring on the traction rod, and locks the hook. Then the worker can climb up through the ladder frame and the climbing pole. During the climbing process, the worker needs to rotate the limit plate upwards at each distance, so that the limit plate is threadedly connected with the threaded surface on the slide rod, and when the limit plate moves upwards, it drives the sliding sleeve to slide on the slide rod, thereby ensuring the normal movement of the worker until the worker moves to the designated position to act. However, to hang the hook on the hanging ring, the operator still needs to rotate the limit plate, and the operator needs to rotate the limit plate again after climbing one end of the distance. The operation steps are relatively cumbersome and the climbing efficiency is slow.
[0005] Therefore, it is necessary to provide a power communication tower anti-fall device to solve the above technical problems. Utility Model Content

A power communication tower anti-fall device comprises: a tower 1;
[0028] A climbing frame 2, the climbing frame 2 is fixedly installed in the middle of the front of the pole tower 1, a limiting frame 3 is fixedly installed on one side of the outer surface of the pole tower 1, a slide groove 6 is opened on one side of the surface of the limiting frame 3, and a clamping groove 8 is opened on one side of the inner wall of the slide groove 6;
[0029] A connecting device 7, wherein the connecting device 7 is slidably mounted inside the slide groove 6, and the connecting device 7 comprises a slider 71, a mounting hole 72 and a setting groove 73. The slider 71 is slidably mounted inside the slide groove 6, the mounting hole 72 is provided on one side of the surface of the slider 71, and the setting groove 73 is provided on the other side of the outer surface of the slider 71;
[0030] A fixing rod 9, wherein the fixing rod 9 is fixedly installed on one side of the inner cavity wall of the setting groove 73, a stopper 11 is fixedly installed on one end of the fixing rod 9, a first elastic member 10 is sleeved on one side of the outer surface of the fixing rod 9, a moving block 12 is sleeved on the other side of the outer surface of the fixing rod 9, a setting hole 13 is opened in the middle of one side of the moving block 12, one side of the setting hole 13 is connected to an active cavity 14, and a clamping block 15 is fixedly installed on the other side of the moving block 12.
[0031] There are multiple card slots 8, and the multiple card slots 8 are equidistantly opened on the front side of the inner cavity wall of the slide groove 6 from top to bottom, and the card slots 8 are triangular in shape.
[0032] One end of the first elastic member 10 is fixedly connected to the moving block 12 , and the restoring elastic force of the first elastic member 10 pushes the moving block 12 to move, and the moving block 12 pushes the clamping block 15 to move out of the setting groove 73 .
[0033] The clamping block 15 is triangular in shape and matches the clamping slot 8 .
[0034] A base 4 is fixedly mounted on the bottom of the tower 1 .
[0035] The first elastic member 10 adopts a spring structure, the block 15 is a triangular block with an inclined surface at the top. When the right-angled surface at the bottom of the block 15 is inserted into the slot 8, when the slider 71 is subjected to a downward force, the right-angled surface at the bottom of the block 15 will not squeeze out of the slot 8, thereby achieving a protective effect.
[0036] The working principle of the anti-fall device for electric communication tower provided by the utility model is as follows:
[0037] During operation, the climber first hangs the hook on the outer surface of the slide block 71 through the mounting hole 72 , and then steps on the surface of the climbing frame 2 to climb upward.
[0038] The slider 71 slides inside the slide groove 6 , and the clamping block 15 is restricted by the inner wall of the slide groove 6 and squeezed into the setting groove 73 . The clamping block 15 drives the moving block 12 to move into the setting groove 73 and squeeze the first elastic member 10 .
[0039] When the slider 71 slides upward inside the slide groove 6 and the card slot 8 is connected to the setting groove 73, the card block 15 is not restricted, and the restoring elastic force of the first elastic member 10 pushes the moving block 12 and the card block 15 to move, and the card block 15 moves out of the setting groove 73 and is embedded in the inside of the card slot 8.
[0040] As the climber continues to climb up, the top slope of the block 15 squeezes the slope of the slot 8, so that the block 15 is squeezed into the interior of the setting slot 73 again, and the slider 71 continues to slide, waiting for the next slot 8 to be connected to the setting slot 73.
[0041] Compared with the related art, the power communication tower anti-falling device provided by the utility model has the following beneficial effects:
[0042] The utility model provides an anti-falling device for a power communication pole tower. A hook is installed on the surface of a slider 71 through an installation hole 72. When an operator climbs, a pull rope drives the hook to pull the slider 71 to slide on the surface of a slide groove 6. The clamping block 15 is sequentially embedded into the clamping groove 8 connected to the setting groove 73 as the slider 71 moves. The device has a simple structure and strong practicality. When the operator climbs the pole tower 1, there is no need to pull the hook frequently. The hook and the connecting device 7 will move with the operator to improve the climbing efficiency. At the same time, under the restriction of the clamping groove 8, the slider 71 is not easy to slide downward, thereby providing anti-falling protection for the climber.
[0043] Second embodiment
[0044] Please refer to Figure 5 and Figure 6 Based on the power communication pole tower anti-falling device provided in the first embodiment of the present application, the second embodiment of the present application proposes another power communication pole tower anti-falling device. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.
[0045] Specifically, the difference of the anti-falling device for a power communication pole tower provided in the second embodiment of the present application is that, in an anti-falling device for a power communication pole tower, limiting rods 16 are fixedly installed on both sides of the surface of the limiting frame 3, a slide plate 17 is sleeved on one side of the outer surface of the limiting rod 16, and a second elastic member 19 is sleeved on the other side of the outer surface of the limiting rod 16, and a limiting block 18 is fixedly installed on one end of the limiting rod 16.
[0046] An extrusion block 20 is fixedly mounted on the surface of the slide plate 17 , and a communication cavity 21 is opened on the surface of the limiting frame 3 .
[0047] The second elastic member 19 adopts a spring structure, and the restoring elastic force of the second elastic member 19 pushes the slide plate 17 to move toward the side of the limit block 18. The slide plate 17 drives the extrusion block 20 to move, so that the extrusion block 20 is separated from the connecting cavity 21. When the slide plate 17 moves toward the side of the limit frame 3, it drives the extrusion block 20 to be embedded into the connecting cavity 21 and inserted into the inside of the card slot 8, and the card block 15 is pushed out of the card slot 8.
[0048] The working principle of the anti-fall device for electric communication tower provided by the utility model is as follows:
[0049] During operation, the operator first holds the slide plate 17 toward the side of the limit frame 3, and the slide plate 17 drives the extrusion block 20 to be embedded into the interior of the connecting cavity 21. The extrusion block 20 moves into the slot 8 and blocks the slot 8, so that the block 15 is squeezed into the interior of the setting groove 73. The block 15 is not restricted, and the climber can climb down.
[0050] Compared with the related art, the power communication tower anti-falling device provided by the utility model has the following beneficial effects:
[0051] The utility model provides an anti-falling device for a power communication pole tower. By moving a slide plate 17 to slide on the surface of a limit rod 16 and squeeze a second elastic member 19, the slide plate 17 drives an extrusion block 20 to move, and the extrusion block 20 enters a connecting cavity 21 and a card slot 8, and pushes a card block 15 out of the card slot 8. The device has a simple structure and is highly practical, and is convenient for operators to climb down from a climbing frame 2. When the operator is about to fall downward, the operator leaves the slide plate 17, and the restoring elastic force of the second elastic member 19 makes the extrusion block 20 leave the card slot 8, and the card block 15 is not restricted and is stuck inside the card slot 8, so that the connecting device 7 and the hook are restricted, and the climbing personnel are prevented from falling, thereby improving the anti-falling effect.
