Description

Technical Field

[0001] This utility model relates to the field of safety protection structure technology, specifically to a scaffolding safety device. Background Art

[0002] Scaffolding is generally used in high-altitude operations. Therefore, scaffolding is used wherever there is high-altitude work, whether indoors or outdoors. The main function of scaffolding is to provide a support platform for workers performing high-altitude work, so the application of scaffolding is very extensive.

[0003] Because of the high-altitude work, and the fact that the scaffold itself is a metal frame, there is no good protective structure in addition to the original structure used for construction, so there is a certain safety risk. In order to facilitate the construction of scaffolds, they are generally lightweight structures, so it is not convenient to add too many components, otherwise it will affect the construction of the scaffolds and increase the burden of high-rise construction. Therefore, a scaffold safety device is established. Utility Model Content

A long side plate is provided on both sides of the shelf, and a short side plate is provided at both ends of the shelf. The shelf has slots near its four sides. A vertical pole is fixedly connected to the top side wall at both ends of the long side plate. A guardrail is fixedly connected between two vertical poles. A branch rope is slidably suspended on the guardrail, and a protective rope is fixedly connected to one end of the branch rope.

[0005] As a preferred embodiment of this utility model, the bottom sidewalls of the long side plate and the short side plate are fixedly connected with a card plate, the size of the card plate corresponds to the card slot, the card plate is snapped into the corresponding card slot, and the long side plate and the short side plate are hollow structures.

[0006] As a preferred embodiment of this utility model, an anti-slip pad is fixedly connected to the top side wall of the shelf, a rotating shaft is fixedly connected to one side edge of the bottom of the long side plate, the rotating shaft is rotatably connected to the two sides of the shelf, and the short side plate is detachably connected to both ends of the shelf by a clamping plate.

[0007] As a preferred embodiment of this utility model, two branch ropes are provided, and a hook is fixedly connected to the end of each branch rope away from the protective rope. Both the protective rope and the branch ropes are elastic ropes, and a control box is provided at the end of the protective rope away from the branch rope.

[0008] As a preferred embodiment of this utility model, the control box has an inner groove, and a rotating column is rotatably connected between the inner walls of the inner groove. One end of the protective rope extends into the inner groove and is wrapped around the rotating column.

[0009] As a preferred technical solution of this utility model, a side groove is provided on one side wall of the inner groove, and fixed ratchet teeth are uniformly and fixedly connected to the inner ring wall of the side groove. A follower column is rotatably connected to the side groove, and a movable ratchet tooth is uniformly and movably connected to the outer ring wall of the follower column through a torsion spring. The fixed ratchet teeth and the movable ratchet teeth correspond to each other, and one end of the rotating column is fixedly connected to one end of the follower column.

[0010] As a preferred embodiment of this utility model, a connecting rope is fixedly connected to the side wall of the control box away from the branch rope, and a hook is fixedly connected to the end of the connecting rope away from the control box. The connecting rope is connected to the high-altitude work safety belt through the hook.

[0011] This utility model has the following advantages: After the shelf is placed on the support frame, the long side plate that is vertically downward is lifted to an upright position. At the same time as the long side plate is lifted, the locking plate will also be inserted into the corresponding slot to achieve a snap-fit ​​connection. The upright long side plate can protect the workers and prevent them from falling into the air and causing safety problems. When the support frame is erected vertically on its own, the short side plate is connected to both ends of the shelf, forming a four-sided anti-fall-into-air function with the two long side plates. When multiple support frames are assembled horizontally, there is no need to install short side plates between every two shelves. Only short side plates need to be installed at the ends, which improves the convenience and flexibility of assembling and erecting the support frame. At the same time, because the long and short side plates are hollow structures, the weight of the shelf is reduced, reducing the burden of high-altitude construction and the workload of the construction personnel.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to Figure 1-3This utility model discloses a scaffolding safety device, including a support frame 1, on which a shelf 2 is detachably placed. A long side plate 3 is provided on both sides of the shelf 2, and a short side plate 4 is provided at both ends of the shelf 2. The shelf 2 has slots 16 near the four sides. A vertical pole 5 is fixedly connected to the top side wall at both ends of the long side plate 3. A guardrail 6 is fixedly connected between the two vertical poles 5. A branch rope 8 is slidably connected to the guardrail 6, and a protective rope 7 is fixedly connected to one end of the branch rope 8.

[0018] Both the long side panel 3 and the short side panel 4 are fixedly connected to the bottom side walls with a clamping plate 17. The size of the clamping plate 17 corresponds to the clamping slot 16. The clamping plate 17 is snapped into the corresponding clamping slot 16. The long side panel 3 and the short side panel 4 are hollow structures. The top side wall of the shelf 2 is fixedly connected with an anti-slip pad. The bottom edge of the long side panel 3 is fixedly connected with a rotating shaft 15. The rotating shaft 15 is rotatably connected to the two sides of the shelf 2. The short side panel 4 is detachably connected to both ends of the shelf 2 through the clamping plate 17.

[0019] The technical effects of this solution are as follows: First, the shelf 2 is placed on the support frame 1. Then, the long side plate 3 is lifted. As the long side plate 3 is lifted, the clamping plate 17 fixed at its bottom is also inserted into the clamping slot 16. The long side plate 3 is stabilized in an upright position by the buckle connection. Then, the short side plate 4 is vertically connected to both ends of the shelf 2 through the clamping slot 16. The long side plate 3 and the short side plate 4 protect the shelf 2 from falling and causing safety accidents, effectively improving the safety protection performance of the support frame 1. Moreover, because the long side plate 3 and the short side plate 4 are hollow structures, the weight of the shelf 2 can be reduced, thereby reducing the burden of high-altitude construction and not placing a high load on the construction personnel. Furthermore, the installation of the short side plate 4 can be adjusted according to the actual situation, improving the flexibility and convenience of construction.

[0020] Two branch ropes 8 are provided. Each branch rope 8 has a hook fixedly connected to the end away from the protective rope 7. Both the protective rope 7 and the branch ropes 8 are elastic ropes. A control box 9 is provided at the end of the protective rope 7 away from the branch rope 8. An inner groove 11 is opened inside the control box 9. A rotating column is rotatably connected between the inner walls of the inner groove 11. One end of the protective rope 7 extends into the inner groove 11 and is wound around the rotating column. A side groove 12 is opened on one side wall of the inner groove 11. Fixed ratchet teeth 13 are evenly fixedly connected to the inner wall of the side groove 12. A follower column is rotatably connected to the side groove 12. The outer wall of the follower column is evenly movablely connected to the movable ratchet teeth 14 through a torsion spring. The fixed ratchet teeth 13 and the movable ratchet teeth 14 correspond to each other. One end of the rotating column is fixedly connected to one end of the follower column. A connecting rope 10 is fixedly connected to the side wall of the control box 9 away from the branch rope 8. A hook is fixedly connected to the end of the connecting rope 10 away from the control box 9. The connecting rope 10 is connected to the high-altitude work safety belt through the hook.

[0021] The technical effect of this solution is as follows: A horizontal guardrail 6 is connected to the long side plate 3 via a pole 5. One of the branch ropes 8 is connected to the guardrail 6 via a hook. Then, the connecting rope 10 is connected to the worker's high-altitude work safety belt via a hook, thereby providing fall protection for the worker. Because there are two branch ropes 8, when it is necessary to replace the guardrail 6, the spare branch rope 8 is used for connection. After the connection is completed, the previous branch rope 8 is released. This ensures that there is always a branch rope 8 connected to the guardrail 6, avoiding safety accidents caused by the gap during replacement.

[0022] Specifically, when using this utility model, the support frame 1 is placed stably, and then the shelf 2 is built on the support frame 1. Then, the vertically downward long side plate 3 is lifted to become an upright body. The stability of the long side plate 3 after being erected is improved by the connection between the clamping plate 17 and the clamping groove 16. Different numbers of short side plates 4 are used according to the construction requirements. The short side plates 4 are installed at the end of the shelf 2 by the buckle connection between the clamping plate 17 and the clamping groove 16. The short side plates 4 and the long side plates 3 can protect the area around the shelf 2 from falling, improving the overall safety performance. The branch rope 8 is connected to the guardrail 6 by a hook. When a fall occurs, the protective rope 7 will drive the rotating column to reverse. In this way, the movable ratchet 14 will abut against one side of the fixed ratchet 13, ensuring that the rotating column will no longer rotate, thereby locking the protective rope 7. At the same time, the protective rope 7 and the branch rope 8 are set as elastic ropes, which can buffer the kinetic energy generated by the sudden stop of the fall, and protect the workers to the greatest extent.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the 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 or all of the technical features therein.
