Abstract

The utility model provides a quick drop stabilizer in tall buildings, and the stabilizer is mainly used to carry the fleeing people to drop to the ground safely when accident occurs in tall buildings. A cable wire (4) is wound around a bobbin disc (8) after passing through a fixed damp shaft (14) and a movable damp shaft (16) in a serpentuate method. The lower part of a bracket (7) of a bobbin disc is connected with a cushion (10) through a rope ring (9) and a connecting rope (11). A fixed seat board (15) provided with a fixed damp shaft is rigidly connected with an arc bracket (18) by bolts, and a movable seat board (19) is arranged between the fixed seat board and the arc bracket. A screw thread on the left end of a crank (20) supported on the arc bracket is screwed in the screw hole of the movable seat board. Rotating the crank can cause the movable seat board to drive the movable damp shaft to move from left to right, and then the distance between the movable damp shaft and the fixed damp shaft can be adjusted. By the adjustment, the drop speed can be adjusted and controlled steplessly within the prescribed range, and the most safe drop speed can be limited. The utility model has simple operation, and has a ground-falling cushion protector.

Description

The quick steady stopping device of high building

Technical field

The utility model belongs to safety, safeguard, relates to the skyscraper escape device, specially refers to a kind of quick steady stopping device.Be mainly used in the skyscraper contingency, under the situation that normal channel can't use, the load escape personnel drops to ground quickly and safely by wall outer side.

Background technology

Escape device is activated use, all be that incident is unexpected in most cases, situation danger, situation is urgent, this just needs escape device to be easy to handle control, can the load survivor be out of danger quickly and safely, arrive safety place, and will avoid the survivor injured once more in the escape process as far as possible.Present known high-rise life saving lowering means kind is more, and structure is different, but abundant inadequately to taking all factors into consideration of escape overall process (from lowering means be fixed to escape personnel's safe falling to ground).

Summary of the invention

The utility model provides a kind of more suitable quick steady stopping device of novel high building.This device not only can limit maximum safe decrease speed, and can carry out stepless regulatedly to decrease speed, simultaneously provides a kind of buffer protection again, and it is injured to avoid the escape personnel to land.

The technical scheme core content that the utility model adopted is: it is less that steel wire rope is wrapped in the diameter of axle in the mode of crawling, on the fixedly damping axle and active damping axle of spacing compactness, steel wire rope is by these the time, must constantly bend right and left, the bending stiffness of himself has just formed current resistance, and speed is fast more, wheelbase is more little, and resistance is big more.Therefore limit the active damping axle and the fixing maximum spacing of damping axle, just can limit the safe speed of passing through of maximum of steel wire rope; Stepless adjustment active damping axle and the fixing distance between the damping axle, just can stepless control steel wire rope pass through speed.

The utility model mainly is made of hook (1), seal (2), holding rod (3), steel wire rope (4), speed regulator (5), shell (6), support (7), reel (8), becket bridle (9), cushion pad (10), connection cord (11), becket bridle parts such as (12), sees Fig. 1.Wherein speed regulator is seen Fig. 2～Fig. 4 by the axis of guide (13), fixedly damping axle (14), fixed base plate (15), active damping axle (16), shelves reel for rope (17), bow-shaped support (18), movable base plate (19), formation such as crank (20) part of etc.ing.

The steel wire rope (4) that the upper end has hook (1) passes through fixedly damping axle (14) and active damping axle (16) in the mode of crawling, and passes in the middle of two shelves reel for ropes (17) again, is wrapped on the reel (8).Reel (8) is fixed on the support (7), and the bottom of support (7) connects together with cushion pad (10) by becket bridle (9), connection cord (11).Cushion pad (10) top has plush copper to be stuck in the corresponding hole of shell (6).

Being equipped with fixedly, the fixed base plate (15) of damping axle (14) is rigidly connected by bolt with bow-shaped support (18), the movable base plate (19) that is provided with in the middle of fixed base plate (15) and bow-shaped support (18) is bearing in the screw that is threaded into movable base plate (19) of crank (20) left end on the bow-shaped support (18).Rotation crank (20) can make movable base plate (19) drive active damping axle (16) move left and right.When active damping axle (16) moves on to the left side, when being close to fixedly damping axle (14), steel wire rope (4) is in on-position, sees Fig. 2.When active damping axle (16) moves on to the right side, when reaching ultimate range qualification and fixing damping axle (14), under the gravity effect of human body, steel wire rope (4) by the damping axle, is seen Fig. 5 with the maximum safe speed set.

The beneficial effects of the utility model are: (1) is easy and simple to handle, and (2) define maximum safe decrease speed, (3) can be within the scope of regulation stepless regulated decrease speed, (4) provide and land buffer protection.

The specific embodiment

Narrate the specific embodiment of the present utility model below in conjunction with technical scheme and accompanying drawing.

The utility model was in on-position before enabling.

1. with hook (1) quick steady stopping device is hung over suitable, reliable position, be convenient to the escape personnel and step on and take advantage of, see Fig. 6.

2. move downwards and draw cushion pad (10), the plush copper on its top is deviate from from the corresponding hole of shell (6), below being hung in by becket bridle (9), connection cord (11), see Fig. 7.

3. escape personnel's both hands are held holding rod (3) and are located, both feet are stepped on cushion pad (10), vacate a hand-screw after the stance that is two little songs of knee is stood firm and change crank (20), the active damping axle (16) and the fixing distance of damping axle (14) are drawn back, steady stopping device descends according to the speed of escape personnel's adjustment in the scope of setting fast, sees Fig. 8

4. cushion pad when landing (10) at first lands, and under cushion pad and kneed double buffering protection, avoids the escape personnel to land contusion to greatest extent.
