Mechanical descent control device

Abstract

The invention relates to a mechanical descent control device which comprises a main descent control device, a connecting rod, a handle, a rope wheel, a pair of guide clamping wheels, a long bearing fireproof rope and a hanging ring, wherein the main descent control device is provided with a conical shell, and the lower end of a side wall of the shell is provided with a hole for the handle to extend out; a brake shoe pair is fixed at the upper edge of the connecting rod, and the lower edge is provided with a branch shaft connected with the handle; the handle is vertically connected with the connecting rod, and the long end of the handle transversely extends out of the shell, while the other end is connected with the shell through a small shaft; the rope wheel is floated between the brake shoe pair and the handle; the pair of the guide clamping wheels are fixed at the opening at the upper end of the shell, and a circuity guide wheel is arranged below the right guide clamping wheel; the long bearing fireproof rope is wound around the rope wheel, and one end of the rope is drawn out by the pair of guide clamping devices, while the other end is led out through the circuity guide wheel; the hanging ring used for hanging a human body is fixedly arranged in the middle at the lower end of the shell; and two sides of the rope wheel are provided with brake sheets fixed on the shell. The mechanical descent control device has the advantages of small volume, light weight, controllable speed, safety, reliability, convenient carrying and use and low manufacturing cost. Users need to be trained and can carry out self rescue and escape while fire hazards, earthquakes, and the like occur.

Description

technical field [0001] The invention relates to an escape device, in particular to a mechanical descending device. Background technique [0002] At present, the generally used rescue descending device mainly contains the following two types: one is the XJS1 planetary wheel type high-rise building descending device, which is large in size and heavy in weight. Problems such as falling are prone to occur during the descent. The other is the GJH type high-altitude life-saving descending device, which has a novel and compact structure, small size, light weight, and is easy to carry and hang. It can be used by firefighters when they save lives, evacuate and evacuate materials in high-rise building fires. Since special training is necessary to use it, it is difficult to carry out civilian promotion. [0003] And the sudden disaster that takes place in the daily life makes people's life property loss heavy, and many people are buried in the disaster because of having missed the be...
