Description
Technical field
The present invention relates to a kind of lifting device, especially a kind of continuous lifting high-altitude Quick rescue platform.
Background technology
Currently, the lifting device of fire-fighting and rescue, state-of-the-art is exactly high-altitude hydraulic pressure aerial ladder of cranking arm.It cranks arm high-altitude hydraulic pressure aerial ladder
The advantages of be steady safety.But high-altitude hydraulic pressure aerial ladder of cranking arm can only convey personnel by lifting again and again, efficiency is low,
It is possible that losing best rescuing machine meeting.Therefore, a kind of efficient continuous lifting high-altitude Quick rescue platform is designed, is to need at present
Technical problems to be solved.
Invention content
Technical problem to be solved by the invention is to provide a kind of efficient continuous lifting high-altitude Quick rescue platforms.
The present invention the technical solution to solve the technical problem is that：
Continuous lifting high-altitude Quick rescue platform, by motor, driving pulley, fixed pulley group, running block, small reel, non junction
Wire line thimble, landing pulley and rope clip composition, the output shaft of motor and the wheel shaft power of driving pulley connect, non junction steel wire
The winding of becket bridle is in proper order：Driving pulley → landing pulley → fixed pulley group → running block → driving pulley, wherein determining cunning
The different pulleys of wheel group are wound with several circles from running block between different pulleys, and several circles are wound on driving pulley, small
Reel rotation is fixed on the wheel carrier of landing pulley, and suspension hook frame is fixed on the wheel shaft of running block, fixed on suspension hook frame
There is suspension hook, height-regulating steel wire rope is wound on small reel, one end and small reel that steel wire rope is turned up are fixed, and the another of steel wire rope is turned up
One end is fixed with suspension hook.
As a preferred embodiment of the present invention, the rope clip is mainly made of inner sleeve and housing, the appearance of inner sleeve
Face is the down big up small conical surface, and the inner surface of housing is the matched conical surface in outer surface with inner sleeve, housing and has two by inner sleeve
A half set is constituted, and two and half sets of housing are joined by axis pin, and symmetrically handle is welded on two and half sets of housing of outer wall
Hand and closing piece have symmetrical lockhole on symmetrical closing piece, have mortise lock in symmetrical lockhole, outer at two and half sets of inner sleeve
There is threaded hole on wall, is oriented on two and half sets of housing of outer wall and erects elongated slot, guider screw is equipped in threaded hole.Work
When, lock is opened, so that inner sleeve " is embraced " steel wire rope, then inner sleeve, housing is closed up and simultaneously " locked ".Since the outer surface of inner sleeve is in
Certain taper, top diameter is small, following diameter is big；It is intended to decline with steel wire rope when under gravity of the rope clip in rescue object
When, it is inside sleeved between steel wire rope under the action of frictional force, will be moved up with respect to housing；At this point, housing will force inner sleeve more
Steel wire rope tightly " is embraced ", to not make rope clip fall on a steel cord.Then, rescue object can be promoted with steel wire rope
Or decline.What needs to be explained here is that：Rescue personnel and by rescue object must utilize driving pulley on steel wire rope lift, it is no
Then, Succor plain stage is may result in tumble.In inoperative, the seizing wire of reel should be packed up, Succor plain stage is made to be in most
The pulley mechanism can be tied up placement by lower position along the telescopic arm of vehicle in this way.
As a preferred embodiment of the present invention, the fixed pulley group has 13 fixed pulleys, the running block to have
13 movable pulleys, so pulley block ratio is 26.
If the maximum height of Succor plain stage is 75 meters, then more the multiplying power of pulley blocks can find out the minimum altitude of Succor plain stage
For：26=5.8 meters of 75X2 ÷.This height is less than two floors height.Illustrate, is less than 5.8 meters when rescuing height, then no longer needs
It is rescued using pulley mechanism implementation.
Compared with prior art, the present invention can uninterrupted continuous conveying, work efficiency is high.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the axonometric drawing of part 8 in Fig. 1；
Fig. 3 is the sectional view of Fig. 2（Along guider screw）.
Specific implementation mode
