Description
Technical field
The present invention relates to escape device, specifically, when occurring the major disasters such as fire, earthquake, when elevator is stopped transport, from high level
On building, along open air by a kind of personal device for being gently downloaded to ground, it is adapted to use on high-rise.
Background technology
CN203591532U discloses a kind of individual's high-rise building escape device, and it includes forward and backward end cap, forward and backward end cap structure
Into housing, a haulage cable is sequentially sleeved on left guiding rope sheave, main rope sheave and right guiding rope sheave, the two ends of traction steel wire set
Each one hook of connection.The suspension hook on housing is hung on high-rise when using, survivor hangs over one of
On the waist of oneself, jump off, end haulage cable declines under survivor's Action of Gravity Field, main rope sheave rotation, and then ring gear, OK
Star-wheel, sun gear, main shaft, friction bar and friction plate rotate simultaneously.When dropping excessive velocities instantly, bear under the influence of centrifugal force
Two fan-shaped friction plates for carrying wheel overcome the pulling force of extension spring to shift to dampened disk, with dampened disk friction, damp rotary speed, decline
Slow down, survivor is gently landed.The hook of the other end of haulage cable is gone up simultaneously, meets another survivor.It lacks
It is it without brake gear to fall into, once above-mentioned damping unit breaks down, consequence is hardly imaginable, thus its safety measure compared with
It is few.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to provide a kind of the personal with high-rise escape dress of strap brake function
Put, be specifically on CN203591532U plus with brake gear.
The object of the present invention is achieved like this：It includes housing, a haulage cable and left and right guiding rope sheave, its
It is characterized in：It also includes a pair of brake gears；Each brake gear is that lock pin is nut, cylindrical pin and circle from bottom to top
Tapered pin head, the top half of lock pin is placed in pipe intracavitary, and there are the lockpin hole that lock pin can be passed through, pipe in the center of circle of pipe bottom end cover
The upper end of chamber is in the infundibulate being engaged with conical plunger, and the diameter of circular cone bottom surface is more than the diameter of pin, in the upper of pin
End forms one and encloses convex shoulder；Inner spring is enclosed on the intraluminal pin of circle, using convex shoulder and pipe bottom end cover as inner spring seat；Outer spring
It is enclosed on the pin outside pipe chamber, using pipe bottom end cover and nut as outer spring seat；A rope passage is opened in the axle center of lock pin, is led
Draw steel wire penetrating rope passage, haulage cable coordinates with rope passage for gap；There are three radial direction steel at circular cone sustained height
Pearl passage, the central angle that three radial direction steel ball passages are between same plane, two neighboring steel ball passage is 120 °, each
Steel ball passage sets a steel ball, and steel ball passage coordinates with steel ball for gap, and the diameter of steel ball is more than the length of steel ball passage；
A brake gear is fixed the left and right end of housing is each；Haulage cable through left and right guiding rope sheave, per one end from
The upper end of homonymy brake gear is passed through after respective rope passage, connects a hook.
Suspension hook is hung on high-rise when using, survivor is by one of hook as right-hand member hangs over oneself
On waist, jump off, the end haulage cable declines under survivor's Action of Gravity Field.When decrease speed is accelerated suddenly, i.e., left end brakes
The haulage cable of device, which is moved up, produces larger acceleration, drive through lock pin move up, make cone plunger
Enter to the hopper base of pipe chamber, three steel balls are moved under the pressure of funnel to the rope passage positioned at the center of circle, from three directions
Haulage cable is clamped, prevents haulage cable from moving, brake is realized.When external force is by the haulage cable of left end brake gear
Drag downwards, lock pin is moved down, make cone plunger towards the direction movement for leaving funnel, three steel balls are retracted, the traction steel wire
Rope can be continued to run with；When survivor hangs over left end on the waist of oneself, then the brake gear of right-hand member is run, and running is such as
It is upper identical.
The effect of inside and outside spring is the stroke for adjusting lock pin, and the effect of specifically inner spring is the stroke for increasing lock pin, and
The effect of outer spring is the stroke for shortening lock pin, and then adjusts the locked sensitivity of haulage cable.
The present invention adds brake gear on the basis of CN203591532U, makes the present invention more safe and reliable.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the schematic diagram of the present invention.
Fig. 2 is the brake gear longitudinal sectional view on the right of Fig. 1.
Fig. 3 is Fig. 2 A-A sectional views.
Embodiment
Referring to Fig. 1, it includes housing 6, haulage cable 4, left guide rope 1 and right guiding rope sheave 3, and it also includes one
To brake gear 5；
Referring to Fig. 2 and 3, each brake gear is that lock pin is nut 57, cylindrical pin 53 and cone from bottom to top
Plunger 52, the top half of lock pin is placed in the inner chamber of pipe 54, and there is the lockpin hole that lock pin can be passed through in the center of circle of pipe bottom end cover 51, circle
The upper end of tube chamber is in the infundibulate being engaged with conical plunger, and the diameter of circular cone bottom surface is more than the diameter of pin, in pin
Upper end forms one and encloses convex shoulder 521, and inner spring 55 is enclosed on the intraluminal pin of circle, using convex shoulder and pipe bottom end cover as inner spring
