Problems solved by technology

[0003] The self-rescue device with this structure, in actual use, because the escaper will accelerate the descent under the action of gravity, and the friction force of the friction plate is only related to the pressure between it and the rope reel, so it is difficult to achieve a uniform rate of descent. Poor stability; moreover, the escaper needs to manually operate the brake handle to brake and assist in controlling the descent speed of the rope. It is difficult for escapers to control the brake lever due to panic, and it is even more impossible for women, children and the elderly
Therefore this self-rescue device has its application greatly limited due to its need for manual control and operation

Embodiment Construction

[0015] The structure of the present invention is as figure 1 Shown, it comprises support 1, and support 1 rear portion has installation hole (not shown in the figure), and this device can be installed on the exterior wall window position of high-rise building through installation hole with expansion bolt.

[0016] A hoisting wheel 2 is arranged on the right side of the bracket 1, and a rope 3 is wound on the hoisting wheel 2. One end of the rope 3 is fixedly connected to the hoisting wheel 2, and the other end can be tied to a hanging basket device or a device capable of fixing and binding the human body. .

[0017] The left side of the hoisting wheel 2 is provided with a speed changer 4, the speed changer 4 is an adjustable speed changer, in which the transmission gear is connected with a shift fork 42, and the other end of the shift fork 42 has a handle 43, and the handle 3 passes through the speed changer housing and can be moved along it. The corresponding chute slides; t...

Abstract

A life-saving mechanism for high building or the like is composed of supporting frame, winding wheel, rope wound on said winding wheel, and hydraulic speed reducer connected to the axle of said winding wheel.

Description

technical field [0001] The present invention pertains to devices for ascending and descending persons from buildings or the like. Background technique [0002] With the improvement of social and economic level, the urbanization process is getting faster and faster, and there are more and more high-rise buildings in large and medium-sized cities. Be questioned, for this reason, people begin to study high-altitude self-rescue escape device, and the Chinese utility model patent specification that the patent No. Hook and brake handle, the brake handle is connected with the lever, the lever is matched with the brake wheel, the fixed plate is installed inside the shell, the guide wheel and the brake wheel are installed on the fixed plate, and a hole is opened on the fixed plate where the brake wheel is installed. A rectangular hole is used to install a rope reel at the bottom of the fixed plate, and a friction plate is installed in the center of the r...
