Description

Integrated high-rise escape descent control device

Technical Field

The utility model mainly relates to a ware technical field slowly falls especially relates to an integral type high building ware slowly falls of fleing.

Background

The descent control device is a common fire-fighting and life-saving device, is mainly applied to high-rise buildings and high-altitude equipment, when a fire disaster happens, trapped people at the high-rise can sleeve safety belts on the bodies of the people, and the people slowly descend to the ground at a safe speed by utilizing a speed reducing mechanism inside the descent control device, so that the people can escape and save themselves quickly.

In the prior art, the descent control device has two forms: the first one is that the descent control device and the rope disc are fixedly arranged at the window, balcony or roof of the building, when in use, trapped people directly pull out the safety belt from the rope disc to be sleeved on the body, and then can slowly descend for escaping; the second type is to install a hook on the wall in advance, when in use, the descent control device is fixed on the hook, then the rope disc is thrown downstairs, trapped people sleeve the safety belt on the body, and the rope disc descends at a constant speed after climbing out of the house to realize escape. However, both of these prior art techniques have significant drawbacks: the first descent control device is of a pre-installed type, so that the installation time is saved during escape, a rope disc does not need to be thrown out of a window, and a descent control route cannot be flexibly selected according to the scene of fire. Moreover, because the descent control device and the rope disc are fixed at a window or outdoors all the year round, the steel wire rope and the internal parts of the descent control device are easy to corrode and rust, thereby shortening the service life and even influencing the safety performance in use. When the second descent control device is used, the rope disc needs to be thrown out of the window, the process can cause damage to the escape personnel on the low floor or rescue personnel located below the floor, and the risk that the safety belt is hung in the half-empty space and cannot complete descent control escape exists.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the not enough of prior art, provide an airtight excellent performance in order to delay the rusty integral type high building of part corrosion ware of slowly falling of fleing.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model provides an integral type high building is fleed and is slowly fallen ware, includes reduction gear, rope dish and cable wire, the middle part and the rope dish of cable wire slide and link to each other, both ends are along syntropy around locating the rope dish, and wherein the end of one end assembles with the reduction gear, still includes closed shell, and reduction gear and rope dish all are fixed in inside the shell, the cable wire both ends are followed wear out in the shell.

As a further improvement of the above technical solution:

the speed reducer is fixed on the upper part of the inner cavity of the shell; a convex shaft is formed in the lower cavity of the shell, and the rope disc is rotatably sleeved on the convex shaft; an opening is formed on each of two sides of the shell, and the end of the steel cable penetrates through the opening.

The top end of the shell is formed with a fixing ring for hanging and fixing the descent control device.

The shell is formed by assembling two cover plates relatively, and a sealing rubber ring is arranged at the joint of the two cover plates.

The rope disc is arranged into a spool, and a groove for the steel cable to penetrate through is formed in the surface of the sleeve of the rope disc.
