Abstract

The utility model relates to a friction reciprocating type high building escape device, which can automatically limit speed to escape in a reciprocating type according to different weights of people, and comprises a fixing slot, a hub, a cooling fin, a friction plate, a sliding key, left and right tooth claws, a spring, a swing rod and a guiding device and the like, wherein friction force can be adjusted in advance through adjusting nuts, a steel rope leads the swing rod and the lift tooth claw connected on the swing rod to rotate and stagger a certain angle wit the right tooth claw through a rubber wheel on the swing bar according to the weight pressed on the swing bar, and pushes a friction end cover to press to the friction plate, thereby generating friction torque, and achieving the purpose of controlling the rotating speed of the hub. The cooling pin on the hub is further favorable for heat dissipation, thereby preventing from generating the phenomena of overheat deadlocking or stalling. When an escaper falls on the ground, another rope can be automatically recycled to the lower end of the escape device, and the second and subsequent escapers safely escape through the same method.

Description

Reciprocating type high-rise escape apparatus rubs

Technical field

The utility model relates to a kind of escape apparatus, is specially the reciprocating type high-rise escape apparatus of friction, can belong to the building security protection facility of building field according to the reciprocating type escape of people's automatic speed-limiting of different weight.

Background technology

Intensive day by day along with the increase of modern building height and building, the potential safety hazard of building is also more and more, and the importance of high-rise escape apparatus is also more and more obvious.Existing high-altitude slow-descending equipment uses that all kinds of corrupt practices creep in, and is slow as aerial ladder speed, and is subjected to the restriction of height; It is injured easily that ground adopts air cushion to catch the survivor; Some escape apparatus complex structures, troublesome poeration depends on electric power control or other people auxiliary operation, can not adapt to different weight people's use etc., and these have all reduced rescue efficiency and rescue effect greatly.

Chinese invention patent " escaping apparatus for building and escape method " (application number: 200810092465.9) disclose a kind of utensil and escape method that is used for building and high-rise escape, the survivor is suspended on the hanger of escaping apparatus for building below by lock sleeve, regulate the braking dynamics of contact roller, when the survivor glides synchronously with escape apparatus, be positioned at of the rotational synchronization release of the rope of runner groove with runner, land until the downslide of survivor's safety, its shortcoming is that frictional force can not be regulated in escape apparatus decline process automatically, no matter escape apparatus is fixing still along with the survivor descends, last survivor's security is the poorest, and its structure is relatively complicated; Patent of invention " high-rise escape apparatus " (application number: 200410049151.2) form by a shelf attachment and acceleration damping winch two parts.By presetting spring pressure and changing into friction brake force according to the centrifugal component of inertial mass that the winch velocity of rotation changes, the personnel decrease speed of making then slowly and at the uniform velocity, its shortcoming is that friction brake wafer is difficult for resetting even is locked after slowing down after the centrifugal inertial force effect, and security reliability is poor; Utility model patent " high-rise escape apparatus " (application number: be a kind ofly to abut against the survivor that friction plate makes different weight with friction pulley and can obtain identical and constant decrease speed 200920143174.8), its shortcoming is that frictional force is non-adjustable, poor stability in the use; Utility model patent " high-rise escape apparatus " (application number: the 200420108410.X) high-rise escape apparatus of being addressed, be with the rotary wheel frame that is wound with tightrope that can on main shaft, rotate on the main shaft, the partner brake(-holder) block that presets of friction pair of collar bush and dististyle, between brake(-holder) block and the nut compression helical spring is arranged, preset brake(-holder) block and hand brake sheet, its shortcoming is can not be raised to aerial realization after escape apparatus is fallen with the survivor more easily to repeat escape.

A kind of simple, safe and reliable, can satisfy different weight people escape, but automatic speed-limiting and easy to operate high-rise escape apparatus necessitate.

Summary of the invention

In order to overcome the deficiency that existing escape apparatus exists, and satisfy the different weight people almost constant requirement of speed of escaping, the utility model provides a kind of escape device, this device can be according to survivor's energy automatic speed-limiting of different weight, and volume is little, and is cheap, simple to operate, can be fit to the safety rescue under the situation of various high-altitudes, especially can realize the reciprocating type circulation rescue of many people, improve rescue efficiency.

The technical solution of the utility model is: reciprocating type high-rise escape apparatus rubs, by fixed slot, wheel hub, fin, friction plate, bearing, feather key, right blade tooth, nut, spring, left side blade tooth, swing arm, main shaft, the friction end cap, guider, steel wire rope, the safety belt hook, fixed block, fixed pulley, rubber wheel is formed, it is characterized in that: fixed block is inserted in the fixed slot, the endoporus of wheel hub is equipped with bearing, main shaft links to each other with bearing, the right side of wheel hub is fixed with friction plate with holding screw, the friction end cap that friction plate is housed is done circumferentially fixing by feather key, right blade tooth and the left blade tooth that can rotate are installed on the main shaft, right blade tooth spring, the adjustment nut of flat key and adjustment spring pressure is fixed, two pairs of rubber wheels are housed on the swing arm, swing arm and left blade tooth are welded into integral body, be wound with the steel wire rope of two bursts of different rotation directions on the wheel hub, rubber wheel on the steel wire penetrating swing arm is to ground, its beneficial effect is, can realize repeating fast escape, but adjust nut preset frictional force, steel wire rope is by the rubber wheel on the swing arm, according to being pressed in weight on the swing arm, make swing arm and connect thereon left blade tooth and rotate and right hock certain angle that staggers, promote the friction end cap and press to friction plate, produce moment of friction, reach the velocity of rotation purpose of control wheel hub.

The reciprocating type high-rise escape apparatus of aforesaid friction, it is characterized in that: wheel hub on the circle, also connects firmly fin is installed in an end of friction plate is housed, during the process high speed that helps escaping friction, good heat dissipation effect prevents the overheated stuck or stall phenomenon generation of friction plate.
