Drum wheel for differential speed automatic controller

Abstract

The invention relates to the field of safety protective tools, in particular to a drum wheel for a differential speed automatic controller during high-altitude operation. The invention discloses a drum wheel for a differential speed automatic controller. The drum wheel has an integrated structure; one side of the drum wheel is in a circular cavity shape, and the other side of the drum wheel is divided into four fan-shaped cavities uniformly by two reinforcing ribs which are vertical mutually; a thread hole through which a hanging belt passes is formed on any one reinforcing rib; and a shaft hole through which a central shaft passes is formed in the center of the drum wheel. Due to the adoption of the drum wheel with the integrated structure, the integral differential speed automatic controller is more stable, and the volume of the drum wheel can be reduced substantially to reduce the volume of the differential speed automatic controller, so that the differential speed automatic controller is convenient to carry and the high-altitude operation is also convenient. In addition, the service life of the differential speed automatic controller can be prolonged substantially.

Description

technical field [0001] The invention relates to the field of safety protective equipment, in particular to a drum used for a speed difference automatic controller during high-altitude operations. Background technique [0002] Now, with the development of science and technology, the ground space is getting smaller and smaller, and a large number of high-rise buildings have sprung up. As the height increases, usually simpler tasks, such as cleaning glass or assembling a certain device, etc., become more difficult due to the high-altitude operation. The following high-altitude difference automatic control fall arrester solves the above-mentioned difficulties, but the general high-speed difference automatic control fall arrester has a larger volume and a more complicated structure, thereby making the cost higher. In particular, the drum is assembled from two and a half drums, which makes the entire high-speed difference automatic control fall arrester very unstable. If the numb...

AI Technical Summary

Problems solved by technology

As the height increases, usually relatively simple tasks, such as cleaning glass or assembling a certain device, etc., become more difficult due to the high-altitude operation

The following high-altitude difference automatic control fall arrester solves the above-mentioned difficulties, but the general high-altitude difference automatic control fall arrester has a large volume and a relatively complicated structure, which makes the cost higher

In particular, the drum is assembled from two and a half drums, which makes the entire high-speed difference automatic control fall arrester very unstable. If the number of times of use is too high, the drum will break down, which will bring serious problems to the construction workers. to safety hazard

Moreover, the drum is assembled, so that the whole drum is larger and takes up a relatively large space, which makes the entire high-speed difference automatic control fall arrester larger in volume and heavier in weight, which is very inconvenient to carry
