[0002] Ladders are a common tool in life, which can assist users to climb up and perform work. In actual applications and enterprise production, manufacturers often install a large number of photovoltaic panels on the top of production plants to provide auxiliary power supply for production equipment. However, in the subsequent maintenance of photovoltaic equipment, workers are often required to use ladders (usually equipped with external cages) to go up and down the facade of the plant. Since the plant and the ladder are relatively steep, there is a certain risk in the process of climbing up and down, and safety protection cannot be effectively guaranteed. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0021] Figure 1-Figure 5 The following is a schematic diagram of the overall structure of a photovoltaic roof ladder cage protection device of the utility model. Figure 1-Figure 5 A photovoltaic roof ladder cage protection device according to the present embodiment includes a ladder 10 fixed to the outer facade of a factory building, and a cage 20 is matched on the outer side of the ladder 10 along its height direction. The cage 20 includes a ring beam 21 with two ends fixed to both sides of the ladder 10 and a plurality of support rods 22 vertically fixed to an inner circle of the ring beam 21. The inner circle of the cage 20 is provided with at least one slide seat 30 vertically slidably sleeved on the outer side of the support rod 22, a connecting rod 40 is rotatably mounted on the outer side of the slide seat 30, an L-shaped guard plate 50 is rotatably mounted on the inclined end of the connecting rod 40, and an elastic member 60 is hingedly mounted on the upper part of the outer side of the slide seat 30 and the other end is hingedly connected to the connecting rod 40; wherein, the L-shaped guard plate 50 is located on one side of the inner bending surface facing the ladder 10, and the staff is tied to the L-shaped guard plate 50 and faces the ladder 10.
[0022] The inner side of the slide 30 has an arc-shaped positioning groove 30a that matches the outer contour of the support rod 22. A plurality of balls 31 are movably arranged in a circle inside the arc-shaped positioning groove 30a and abut against the outer wall of the support rod 22. The arc-shaped positioning groove 30a allows the slide 30 to be stably engaged with the support rod 22. The set balls 31 make the slide 30 move up and down more smoothly and linearly, allowing the staff to be more stable when crawling up and down.
[0023] A magnet block 32 that is magnetically attracted to the support rod 22 is fixed inside the slide 30 and on the inner side of the arc-shaped positioning groove 30a, and there is a gap between the magnet block 32 and the support rod 22. The magnet block 32 is set so that when the staff stops while crawling, the slide 30 can be stably adsorbed on the outer side of the support rod 22, which can greatly reduce the sliding speed of the slide 30, which is beneficial to the stable up and down crawling of the staff; it can be understood that the slide 30 and the mobile protection device are also equipped with locking parts that are fastened to the cage 20 for positioning, such as locking bolts, movable buckles, etc., so that when the slide 30 moves to the ladder 10 and the top of the factory building, it will not slide freely.
[0024] The inner bending surface of the L-shaped guard plate 50 is also covered with an elastic pad 51, and a plurality of hanging rings 52 for convenient connection of straps and buckles are also provided on both sides of the L-shaped guard plate 50. Here, the L-shaped guard plate 50 can be used to conveniently provide protective support for the back and buttocks of the staff, so that the connecting rod 40 and the protective device can act on the staff. At the same time, the elastic pad 51 can effectively improve the comfort and adhesion of the guard plate, and the safety belt tied to the staff can be conveniently buckled and connected through the hanging ring 52, which is simple and convenient.
[0025] The elastic member 60 includes a sleeve 61 with one end hinged to the outside of the sliding seat 30, a push rod 62 that slides and retracts on the inside and the other end of the sleeve 61, and a spring 63 that is arranged on the inside of the sleeve 61 and abuts against the inner end of the push rod 62 at one end. The outer end of the push rod 62 is hingedly mounted to the connecting rod 40. When in use, the sleeve 61 and the push rod 62 will push the connecting rod 40 counterclockwise under the action of the spring 63, and push the L-shaped guard plate 50 toward the direction of the ladder 10 through the connecting rod 40. During actual use, when the worker climbs up and down the ladder 10, his body will drive the connecting rod 40 and the sliding seat 30 to move up and down through the L-shaped guard plate 50. At the same time, the connecting rod 40 will form an elastic push on the L-shaped guard plate 50 under the action of the elastic member 60, so that the worker's body is always passively close to the ladder 10, thereby improving his vigilance and crawling safety. When the worker misses or slips, the L-shaped guard plate 50 will push the worker's body to the direction of the ladder 10 under the action of the connecting rod 40 and the elastic member 60. At the same time, due to the strong linear resistance between the sliding seat 30 and the support rod 22, the double cooperation enables the worker to react in the first time and firmly step on or grab the ladder 10, effectively avoiding falling into the hole, so that the operating safety of the protective device is effectively guaranteed.
[0026] In summary, the photovoltaic roof ladder cage protection device of the present embodiment is used. When the worker climbs up and down the ladder 10, his body will drive the connecting rod 40 and the sliding seat 30 to move up and down through the L-shaped guard plate 50. At the same time, the connecting rod 40 will form an elastic push on the L-shaped guard plate 50 under the action of the elastic member 60, so that the worker's body is always passively close to the ladder 10, thereby improving his vigilance and crawling safety. When the worker misses or slips, the L-shaped guard plate 50 will push the worker's body to the direction of the ladder 10 under the action of the connecting rod 40 and the elastic member 60. At the same time, due to the strong linear resistance between the sliding seat 30 and the support rod 22, the double cooperation enables the worker to react in the first time and step on or hold the ladder 10 firmly.
[0027] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
