Description
Technical field
It the utility model is related to shear energy-absorbing and used during elevator falling buffering lifesaving technology field, and in particular to one kind utilizes shearing
The used during elevator falling buffering car structure of energy-absorbing.
Background technology
In recent ten years, as the increase of China's skyscraper quantity, high rise elevator quantity also rapidly increase, according to statistics,
By the end of the year 2016, national elevator quantity is at 4,900,000 or so, as skyscraper vertical transportation instrument, its high load capacity, big fortune
The present situation generally existing that amount, long period use, while old elevator quantity is increased sharply, especially with the passage of time, nearly more than ten
The elevator that year increases newly will also step into old ranks, turn into the main target of old Retrofit of Elevator.
In recent years, high rise elevator accident in China's still happens occasionally.Counted according to State General Administration for Quality Supervision, whole year in 2016, the whole nation
Elevator accident 48 occurs altogether to rise, dead 41 people, accident quantity and death toll were decreased obviously compared with 2015, elevator safety fortune
Row situation is steady, but elevator safety problem concerns people's life's safety, still should not be underestimated.
The main speed limiter of overspeed protective device and safety tongs at present used in elevator.Limiter of speed is speed responsing and operation
The device of safety tongs, when the car speed of service reaches limit value the 115% of rated speed of lift (be usually), electric signal can be sent
And mechanical action is produced, to cause the braking maneuver of safety tongs.Although elevator safety codes provide that safety tongs must be by limiter of speed
To manipulate, prohibit the use of and clamped by electric, hydraulic pressure or pneumatic shuttle come safe operation.But limiter of speed is still to be controlled by electric signal
, with the use and aging of elevator, the braking that can limiter of speed be operating normally to safety tongs plays vital effect.
When due to tractive force deficiency, control failure or brake failure car crouching bottom occurs for elevator, buffer will absorb sedan-chair
The kinetic energy in railway carriage or compartment, there is provided last protection, to ensure the safety of personnel and elevator structure.Presently used buffer is divided into spring and delayed
Device and hydraulic bjuffer are rushed, wherein spring buffer is spring buffer, can be rebounded again after spring-compressed to extreme position, right
Human body causes secondary injury；And hydraulic bjuffer is hydraulic buffer, without rebound effect after being impacted, but hydraulic system by
The other factors such as temperature have a great influence, it is necessary to which timing is overhauled to ensure the normal use of buffer.
The content of the invention
In order to solve the above-mentioned problems of the prior art, the purpose of this utility model is that providing a kind of utilize shears suction
The used during elevator falling buffering car structure of energy, not against any control device, the completely cut cells and shear plate by being pre-designed
Buffering when occurring to absorb energy during detrusion to realize used during elevator falling.
In order to reach object above, the utility model adopts the following technical scheme that：
A kind of used during elevator falling using shear energy-absorbing buffers car structure, including car 3, the car 3 and supporting frame
Four angle frameworks or surrounding of connecting place are provided with multiple rows of cut cells 1；Also include shear plate 2, be provided with shear plate 2 single with shearing
The slotted hole 4 of first 1 shape and position adaptation, shear plate 2 are connected by cut cells 1 through slotted hole 4 thereon with car 3
Connect, the preset length of car 3 is stretched out in the bottom of shear plate 2 so that when lift car 3 falls, shear plate 2 first with pit ground
Joint, reach the purpose of buffering；Slotted hole 4 on the shear plate 2, its hole length gradually increase with height so that fall
When cut cells 1 be not it is disposable all cut, but segmentation is cut successively, is absorbed fall energy step by step, is reached protection human body
Safety, no more than the requirement of regulation overload.
The shape of the shear plate 2 determines according to the actual size and shape of car 3, is L-shaped, C-shaped or veneer, is L-shaped
When be placed at the corner of square car, be connected with frame structure.
The cut cells 1 is bolt or pin.
The shear energy-absorbing device that the cut cells 1, shear plate 2 and slotted hole 4 are formed is installed on the external frame of lift car 3
On frame, or it is installed on inside car 3；If the car frame rigidity of structure is insufficient, increase rigidity, when enabling to be adapted to fall
Impact, will not occur large deformation, so as to influence the safe living space of occupant in car.
Compared with prior art, the utility model has the advantage that：
The buffering lifesaving car structure that falls involved by the utility model, it can accomplish to set not against any electrified control
It is standby, when elevator falls, the effect for the impact kinetic energy for absorbing used during elevator falling is realized by the detrusion of cut cells 1,
The buffering lifesaving car, manufacturing cost is low, simple in construction, can carry out phase according to actual states such as the shape of lift car, sizes
The design and transformation answered.The use of cut cells 1 simultaneously so that reused after the replaceable cut cells 1 of the device, installation is more
Add simplicity.
