Description

Technical Field

[0001] The invention relates to the technical field of forest stand growth models, and in particular to a roof operation anti-falling device. Background Art

[0002] At present, the construction of substation houses is different. Some roofs have parapets, some are flat, some parapets are 1 meter high, and some are only about 0.2 meters. Due to work needs, when relevant operation and maintenance personnel go to the roof of the substation house to work, according to the regulations and system requirements, the various parts of the safety belts used for high-altitude operations shall not be dismantled arbitrarily, and the damaged ones shall not be used; the safety belts shall be hung on a vertical hook without sharp edges and corners, and cannot be hung low and used high; ropes are not allowed to be used instead, and the hanging must meet the requirements. However, there are no strong and firm safety belt fixing points on the roof, around the house, and on the edge of the roof (the current working practice is: after the workers go up to the roof, they will fix expansion hooks around the roof parapet, use wire ropes to connect various points, and hang the first and second safety belts on the wire ropes; if there is no parapet, the workers will hold the first and second safety belts of the workers; and build scaffolding around the house). During high-altitude operations, workers need to frequently change their working positions to perform operations, and there is no device or structure to fix the first and second safety belts, which causes the workers to commit violations to varying degrees during the work process. At the same time, the personal safety of the workers is seriously threatened and safety cannot be guaranteed.

[0003] There are no strong and firm safety belt fixing points when working at heights on the roofs of substations and around houses. During high-altitude operations, workers need to frequently change their working positions and there are no devices or structures to fix the safety belts. This causes workers to violate regulations to varying degrees during work. At the same time, the personal safety of workers is seriously threatened and safety cannot be guaranteed. Therefore, it is necessary to develop a roof 360° fall prevention device that can facilitate the fixing of safety belts, has flexible steering, and can move laterally. Summary of the invention

[0029] According to the on-site conditions and taking into account factors such as protecting the safety of workers and improving operational convenience, the anti-fall device will be fixed to the center of the roof using expansion screws. The main anti-fall device consists of 4 layers of anti-fall components 203, and each hanging point 201 is provided with 1 and 2 safety ropes, 1 safety belt anti-fall device, and 2 safety belt anti-fall devices. Each layer of structure is connected and fixed with a slewing bearing 101, so that each layer of hanging point 201 can be adjusted independently and 360 degrees without dead ends in the working position. There are 4 layers in total, which can be used by 1-4 people at the same time in different directions at 360° on site. When in use, you only need to hang the 1 and 2 safety hooks on the anti-fall device on the existing safety belt.

[0030] Specifically, the hanging point 201 includes a protection rope 201a arranged on the outside of the rotating disk 102, and a ring 201b arranged at one end of the protection rope 201a; wherein, there are two protection ropes 201a, one end of one protection rope 201a is fixedly connected to the ring 201b, and the other end is connected to the rope collection component 202, and one end of the other protection rope 201a is fixedly connected to the ring 201b, and the other end is connected to the anti-fall component 203; when the human body accelerates downward to prevent the human body from continuing to fall, a protection rope without an anti-fall mechanism can move with the human body to different parts, in addition to a protection rope, plus an anti-fall mechanism can achieve double protection, there are 4 groups of hanging points 201 on the four floors, each point can be safely operated by one person, and an anti-fall device can ensure the security measures of 1-4 people on site, which is safe and reliable and ensures personal safety.

[0031] Furthermore, the rope collecting assembly 202 includes a shell 202a arranged inside the rotating disk 102, a clockwork spring 202b arranged inside the shell, and a self-locking member 202c arranged on one side of the clockwork spring 202b, the self-locking member 202c includes a control button 202c-1, and a latch column 202c-2 arranged inside the shell 202a, the latch column 202c-2 is electrically connected to the control button 202c-1 by signal; the self-locking member 202c allows the rope to be locked at any position to prevent accidental slipping out; the self-locking mechanism may include a ratchet 203d system, when the rope is pulled out, the ratchet 203d allows the rope to move in one direction, but does not allow reverse movement, thereby achieving self-locking; releasing the self-locking mechanism: when the rope needs to be retracted, the user can release the self-locking by a simple action such as stretching forward, so that the rope can move freely and be retracted by the spring.

[0032] Furthermore, the anti-falling assembly 203 includes a housing 203a disposed on one side of the housing 1 202a, a ratchet cover 203b disposed inside the housing 203a, a ratchet main shaft 203c disposed inside the ratchet cover 203b, a ratchet 203d disposed outside the ratchet main shaft 203c, and a control member 203e disposed on one side of the ratchet 203d. The ratchet main shaft 203c is generally made of 45 steel and quenched and tempered material, and its surface is relatively hard, and it is the rotating shaft of the wheel. The ratchet cover 203b is provided to isolate the steel wire rope to prevent the steel wire rope from mixing with the teeth of the ratchet 203d when the steel wire rope is retracted and released, and the anti-falling function is realized through the control member 203e.

[0033] Furthermore, the control member 203e includes a coil spring 203e-1 on one side of the ratchet 203d, a pawl 203e-2 on the other side of the ratchet 203d, a tension spring 203e-3 on one side of the pawl 203e-2, and a wire outlet protection ring 203e-4 on the outside of the shell. The coil spring 203e-1 is mainly used to control the rotation of the ratchet 203d to achieve the function of automatic retraction and extension. The pawl 203e-2 adopts a double stop key, which is used to stop the clockwise rotation of the ratchet 203d to achieve the braking function of the speed differential fall arrester. The wire rope used is a thin and soft aviation wire rope. The fall arrester is frequently retracted and extended during use, which can easily damage the wire rope. The wire outlet protection ring 203e-4 is generally designed to be a symmetrical trumpet-shaped circular ring 201b made of brass. The coil spring 203e-1 is mainly used to control the balance of the double stop key to achieve the function of automatic braking.
