Abstract
Description
Technical Field
[0001] The invention relates to a buffer device, belonging to the fields of safety protection, buffering and electromechanical, and in particular to a buffer device for a safety rope for preventing falling during high-altitude operation. Background Art
[0002] At present, many fields, including construction, electricity, transportation, etc., often have high-altitude construction and operations. According to the requirements of the high-altitude operation regulations, when performing high-altitude operations, safety ropes must be carried for safety protection. At present, ordinary safety ropes rely on the length limit of the safety rope to prevent people from touching the ground when falling from a height, which plays a certain role in protecting the falling people. However, it cannot avoid the huge impact of the rope end on the falling people when the safety rope is exhausted, causing secondary injuries to the falling people. Another type of safety rope with a buffer bag on the market, such as Figure 1 As shown, the falling energy of the falling person can be consumed in stages, which has a certain cushioning effect on the falling person. However, there is still a large impact, and the falling person is still at risk of secondary injury. Summary of the Invention
[0003] In order to solve the above problems, the present invention proposes a high-altitude work anti-fall safety rope buffer device, which forms a certain pre-pressure in the axial direction of the anti-fall safety rope buffer device through the pre-compression of the spring, and the axial pre-pressure of the spring is decomposed into a radial force through the conical surface of the buffer element, and is radially compressed to the anti-fall safety rope through the buffer element, thereby forming a friction force, thereby realizing the effective clamping effect of the buffer element on the anti-fall safety rope. Since the pre-compression force of the spring is certain, the friction damping force formed by the anti-fall safety rope buffer device is also certain. When a high-altitude worker falls and the impact force is greater than the preset friction force between the buffer element and the anti-fall safety rope, the anti-fall safety rope produces relative sliding with the buffer element under the action of the preset friction force, and effectively consumes the falling energy of the falling person through the preset friction force, thereby fully protecting the life safety of the falling person and effectively preventing the falling person from suffering secondary injuries.

[0006] When a worker working at a height falls, the impact force of the fall reaches a preset friction force of the high-altitude work anti-fall safety rope buffer device. Under the action of the preset friction force, the anti-fall safety rope produces relative sliding between the buffer element and effectively consumes the falling energy of the falling person through the preset friction force, fully protecting the life safety of the falling person and effectively preventing the falling person from suffering secondary injuries.
