Pendulum bob descent control device and working method thereof

Abstract

The invention provides a pendulum bob descent control device and a working method thereof. The pendulum bob descent control device comprises a descent control device body, wherein the descent controldevice body comprises a shell, a rope winding wheel, a first gear, a first rotating shaft, a transmission device and a pendulum bob part, the first rotating shaft is rotationally connected into the shell, the rope winding wheel and the first gear are arranged on the first rotating shaft, the transmission device is fixedly arranged in the shell, the first gear is connected with the transmission device, one end of the pendulum bob part is rotationally connected with the inner wall of the shell, and a connecting rod is arranged at the end, close to the transmission device, of the pendulum bob part and connected with the transmission device; and a rope enters the rope winding wheel from one end of the shell and extends out of the shell from the other end of the shell. According to the pendulumbob descent control device and the working method thereof, the structure is simple, and a user can automatically adjust braking force according to body weight.

Description

technical field [0001] The invention relates to the technical field of high-altitude slow-down equipment, in particular to a pendulum slow-down device. Background technique [0002] With the development of my country's social economy, people's material life has improved, and there are more and more high-frequency fire accidents. When a high-rise building encounters a major accident such as a fire or an earthquake, and the people in the building are too late to evacuate due to blocked or destroyed corridors and elevators, they can use the rescue equipment to escape from the accident scene through the window. Therefore solving the current high-rise building fire prevention has been put on the agenda, and the emergency escape and safe evacuation of personnel in high-level buildings is an urgent task. [0003] In order to solve the above technical problems, a kind of high-rise slow-down device has appeared. In the patent document with the Chinese patent application number of 20...

Problems solved by technology

[0004] But according to the technical scheme disclosed in this document, the automatic braking device decelerates the rope pulley through the brake pads so as to achieve the purpose of slowing down. The braking force is the same. When the user is underweight or overweight, it may be impossible to slow down or the braking force is too small, which poses a safety hazard
