Description

The personal high-rise building escape device of strap brake function

Technical field

The present invention relates to escape device, specifically, when the major disasters such as breaking out of fire, earthquake, when elevator is stopped transport, from high-rise, along open air, individual is gently downloaded to a kind of device on ground, it is adapted at high-rise uses.

Background technology

CN203591532U discloses a kind of personal high-rise building escape device, it comprises forward and backward end cap, forward and backward end cap forms housing, and a haulage cable is enclosed within left guiding rope sheave, main rope sheave and right guiding rope sheave successively, and the two ends of traction steel wire cover respectively connect a hook.During use, the suspension hook on housing is hung on high-rise, one of them hangs on the waist of oneself by survivor, jump off, under survivor's Action of Gravity Field, this end haulage cable declines, main rope sheave rotates, and then ring gear, planetary gear, sun gear, main shaft, friction bar and friction plate rotate simultaneously.When instantly falling excessive velocities, the pulling force that two of loadwheel fan-shaped friction plates overcome extension spring under the influence of centrifugal force shifts to dampened disk, with dampened disk friction, damping rotary speed, declines and slows down, survivor is landed gently.The hook of the other end of haulage cable is gone up simultaneously, meets another survivor.Its defect be it without brake gear, once above-mentioned damping unit breaks down, consequence is hardly imaginable, and therefore its safety measure is less.

Summary of the invention

For solving the problems of the technologies described above, the object of this invention is to provide a kind of personal high-rise building escape device of strap brake function, specifically adding on CN203591532U and joining brake gear.

The object of the present invention is achieved like this: it comprises housing, a haulage cable and left and right guiding rope sheave, it is characterized in that: further comprising a pair brake gear; Each brake gear is, lock pin is nut, cylindrical pin and conical plunger from bottom to top, the first half of lock pin is placed in pipe chamber, the lockpin hole that the center of circle of pipe bottom end cover has lock pin to pass, the upper end in pipe chamber is in the infundibulate matched with conical plunger, the diameter of circular cone bottom surface is greater than the diameter of pin, forms a circle convex shoulder in the upper end of pin; Inner spring is enclosed within the intraluminal pin of circle, with convex shoulder and pipe bottom end cover for inner spring seat; Outer spring is enclosed within the pin outside pipe chamber, with pipe bottom end cover and nut for outer spring seat; Open a rope passage in the axle center of lock pin, haulage cable is through rope passage, and haulage cable is matched in clearance with rope passage; Three radial steel ball passages are had at circular cone sustained height place, three radial steel ball passages are in same plane, central angle between adjacent two steel ball passages is 120 °, at each steel ball channel setting steel ball, steel ball passage and steel ball are matched in clearance, and the diameter of steel ball is greater than the length of steel ball passage;

Fix a brake gear the left and right end of housing is each; Haulage cable is through left and right guiding rope sheave, and every one end connects a hook after passing respective rope passage from the upper end of homonymy brake gear.

Hang on high-rise by suspension hook during use, one of them hook such as right-hand member hangs on the waist of oneself by survivor, and jump off, under survivor's Action of Gravity Field, this end haulage cable declines.When decrease speed is accelerated suddenly, namely the haulage cable of left end brake gear moves up and produces larger acceleration, drive through lock pin move up, cone plunger is entered to the hopper base in pipe chamber, three steel balls move to the rope passage being positioned at the center of circle under the pressure of funnel, from three directions, haulage cable is clamped, stop haulage cable to move, realize brake.When the haulage cable of external force by left end brake gear is dragged downwards, lock pin moves down, and cone plunger is moved towards the direction leaving funnel, and three steel balls are return, and this haulage cable can continue to run; When left end hangs on the waist of oneself by survivor, then the brake gear of right-hand member runs, and running is as above identical.

The effect of inside and outside spring is the stroke regulating lock pin, and specifically the effect of inner spring is the stroke strengthening lock pin, and the effect of outer spring is the stroke shortening lock pin, and then regulates the locked sensitivity of haulage cable.

The present invention adds brake gear on CN203591532U basis, makes the present invention safer, reliable.
