Abstract
The invention discloses a buffer device for an elevator ceiling-hitting and ground-touching accident, and belongs to elevator safety buffer devices. Buffer device bodies are arranged at the bottom and the top of a running channel of an elevator cabin respectively. During elevator ground touching or elevator ceiling hitting, the impact force of the elevator cabin is relieved through the soft tension of extension springs; and the impact force is softly and gradually reduced through the soft resilience force of corner springs and the soft resilience force of center springs, and the safety state is achieved.
Description
Technical field
the present invention relates tomanufacturing industry of the lift, particularly elevator safety shock absorber.
Background technology
In current manufacturing industry of the lift, prevention elevator crouching end accident only adopts a spring bottom set, and top is without concrete safety apparatus, and along with the development and improvement of manufacturing industry of the lift, the elevator crouching end and accident probability of rushing to summit reduce gradually, but reduce to be not equal to and can not to occur.
Summary of the invention
For the problems referred to above, the invention provides a kind of elevator and to rush to summit and squat the shock absorber of end accident, effectively dissolve elevator squat the end time, the time of rushing to summit causes the problem of personnel's heavy casualties; This device drops into little, and safety control is good.
For technical solution problem, the present invention is by the following technical solutions: elevator is rushed to summit and squat the shock absorber of end accident, the bottom of passage is run and top is respectively arranged with shock absorber at elevator cabin 1, the shock absorber 7 of bottom is by feet 4, extension spring 3, bracing frame 2, pressure spring is formed, 4 feets 4 are separately fixed at 4 angle ends below elevator cabin 1, 4 feets 4 are highly equal, the top of each feet 4 hangs the equal extension spring 3 of a length, the frame of bracing frame 2 is the quadras that just can hold elevator cabin 1, the diagonal angle of framework is connected with two cross bars 8, the free end of extension spring 3 is connected on 4 angles of bracing frame 2, elevator cabin 1 squat the end time just can fall on bracing frame 2, immediately below 4 angle points of bracing frame 2, bottom surface is provided with pressure spring A5, immediately below the two cross bar intersection points at the diagonal angle of bracing frame 2 framework, bottom surface is provided with pressure spring B6, pressure spring A5 does not contact with bracing frame 2 with the free end of pressure spring B6, copy the shock absorber 7 of a bottom, and the shock absorber this copied is placed on the top that elevator cabin runs passage, placement direction is just contrary with the shock absorber of bottom, and opening is relative, just can fall on bracing frame when elevator cabin is rushed to summit.
further:the top section of described feet 4 bends inwards, and is convenient to hang extension spring 3.
further:the ultimate tensile elongation of described extension spring 3 is less than or equal to the limit contraction height of pressure spring A5 and pressure spring B6, is greater than height during pressure spring A5 and pressure spring B6 static state.
further:described bracing frame 2 is filled to monoblock stay bearing plate.
further:described pressure spring B6 quantity is 1-4 root.
Advantageous Effects: elevator is squatted the end or the time of rushing to summit: by the soft pulling force of extension spring, elevator cabin impulsive force is alleviated, then pass through angle spring, screen resilience that central spring is soft, impulsive force is mildly reduced gradually, reaches safe condition.
