Abstract
A kind of new fall-slowing device for rescuing from high building, for solving existing descending lifeline because friction causes the problem of performance is unstable.It includes buffering wheel, bearing block, rocking bar, hydraulic damper, mounting bracket, and the buffering wheel is the drum that two ends are provided with short axle, and rope is full of in buffering wheel periphery, buffering wheel two ends are provided with rocking bar, the rocking bar is rod-like structure, and rocking bar two ends are provided with through hole, and the mounting bracket is frame structure.The present invention, which is realized, controls the device of decrease speed for hydraulic damper, and very big friction will not occur for the process that hydraulic damper produces power, and new fall-slowing device for rescuing from high building reliable operation, performance are stable.
Description
Technical field
The present invention relates to high-rise slow descent technical field, specifically a kind of new fall-slowing device for rescuing from high building.
Background technology
With the height more and more higher of residential building, when the disasters such as fire occur for residential building, it is necessary to which people are fast from high-storey
Speed is fled from.Therefore, most important is ensured to the life security of people using rational escape apparatus.
Descending lifeline operation principle currently used for high-rise life saving is mainly：Frictionally the frictional force control of by-product life declines
Speed.Therefore, the presence of friction will cause friction piece to produce abrasion, and then influence slow drop effect.
The content of the invention
It is an object of the invention to provide a kind of new fall-slowing device for rescuing from high building, for solving existing descending lifeline because friction is led
Cause the problem of performance is unstable.
The technical scheme adopted by the invention to solve the technical problem is that：A kind of new fall-slowing device for rescuing from high building, its feature
It is that it includes buffering wheel, bearing block, rocking bar, hydraulic damper, mounting bracket, the buffering wheel is the cylinder that two ends are provided with short axle
Rope is full of in shape, buffering wheel periphery, and buffering wheel two ends are provided with rocking bar, and the rocking bar is rod-like structure, and rocking bar two ends are provided with
Through hole, the mounting bracket is frame structure.
Further, it is provided with keyway in the short axle of the buffering wheel two ends.
Further, the rocking bar is separately mounted in the short axle at buffering wheel two ends, and into certain angle between two rocking bars
Degree.
The beneficial effects of the invention are as follows：A kind of new fall-slowing device for rescuing from high building that the present invention is provided, it realizes that control declines
The device of speed is hydraulic damper, and the principle that hydraulic damper produces damping force produces resistance when being and flowing through damping hole by fluid
Power.Very big friction will not occur for the process that hydraulic damper produces power, and reliable operation of the present invention, performance are stable.
Brief description of the drawings
Fig. 1 is schematic diagram of the invention；
Fig. 2 is mounting bracket schematic three dimensional views；
Fig. 3 is the schematic three dimensional views of buffering wheel；
Fig. 4 is rocking bar schematic three dimensional views；
Fig. 5 is hydraulic damper schematic diagram.
In figure：1 buffering wheel, 2 bearing blocks, 3 rocking bars, 4 hydraulic dampers, 5 mounting brackets, 41 its shell bodies, 42 dampings
Covered on device damper rod, 43 dampers, cylinder, 45 damper pistons, 46 springs, 47 damping holes under 44 dampers.
Embodiment
The present invention will be described in detail below in conjunction with the accompanying drawings.
As shown in Figures 1 to 5, the present invention includes 1 buffering wheel, 2 bearing blocks, 3 rocking bars, 4 hydraulic dampers, 5 mounting brackets.
As shown in figure 1, the one end of mounting bracket 5 is arranged on external wall of high-rise building, buffering wheel 1 is arranged on peace by bearing block 2
Shelve and rope is full of on 5 tops, buffering wheel 1, rocking bar 3 is installed in the two ends short axle of buffering wheel 1, the lower end of hydraulic damper 4 is installed
By being hinged on mounting bracket 5, the upper end of hydraulic damper 4 is with rocking bar 3 by being hinged and connected.
During work, rope one end is fixed on escape personnel, and body is hanging in the air, and rope is drawn under gravity
Dynamic buffering wheel 1 is rotated, the rocking bars 3 of buffering wheel both sides also concomitant rotation, because rocking bar 3 connects with hydraulic damper phase 4, therefore, is shaken
Bar can be moved back and forth with fluctuation dampers damper rod 42 under damper in cylinder 44, and cylinder 44 is formed with lid on damper 43 under damper
One closed cavity, the inside is full of hydraulic oil, and damper rod 42 is moved back and forth inside cavity to force hydraulic oil to flow through damper rod
Damping hole 47 on 42 produces damping force, hydraulic damper 4 is produced the power for hindering rocking bar 3 to rotate, can make buffering
The velocity of rotation of wheel 1 is controlled, and the speed that people declines in the air can also be controlled.The effect of slow drop can so be reached.
