Punching, the buffer board is just to elevator car bottom；
Further, the piston rod that the damper assembly is included cylinder body, damping piston and is fixedly connected with damping piston, described
Piston rod is engaged with buffer board in buffer spring passes through buffer board by elevator car compression process, by damping piston to buffer board
Form damping；
Further, the buffer spring is variable-pitch spring；
Further, the pitch of the buffer spring is become larger from bottom to top；
Further, relative with piston rod be provided with the buffer board by can axially directed in the way of be coated at piston rod
Fairlead, is provided with the fairlead for the pedestal with piston rod tip contact；
Further, the pedestal is integrally formed with fairlead and is fixedly installed on buffer board, and buffer board is set for fixation
Put thickening at pedestal to process；
Further, the buffer board upper surface, piston rod upper surface and pedestal lower surface are respectively provided with cushion；
Further, the spring base on the basis of the buffer spring is by being fixed on is installed on basis.
Beneficial effects of the present invention：The elevator of the present invention goes forward one by one the safety device of buffer damping power, using buffer spring with
The structure that damper assembly combines, and damper assembly intervenes damping in buffer spring compression process, forms the buffering resistance that goes forward one by one
Buddhist nun's mode, bottoms out damping force in buffering course in elevator car and gradually increases, and increase process rapid compared with common spring and
Gently, final stage forms buffer damping, realizes the ride comfort of downstream buffer and with enough damping forces, therefore with existing skill
Art compares the damping process that can increase cushion stroke and laddering gradual change, can adopt the less spring of coefficient of elasticity in scheme, after
The damping intervention of phase combines the elastic buffer of early stage, it is adaptable to which express elevator is used, the effect with dynamic application at any time so that
Elevator car bottoms out the comfortableness and reliability of the moment of front and contact Buffer Unit and effectively improves, the peace of hoisting elevator
Full performance.
Description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Fig. 1 is the structural representation of the present invention, as shown in the figure：The elevator of the present embodiment go forward one by one buffer damping power safety dress
Put, including being fixedly installed on elevator bottom for preventing 1 rigid touch bottom buffering component of elevator car and electric in Buffer Unit
The damper assembly of damping is formed during elevator car resilient compression to elevator car, is compressed in Buffer Unit and necessarily (is set)
During degree, there is damping action in damper assembly, form the buffer damping effect that goes forward one by one.
In the present embodiment, the Buffer Unit include being arranged on the basis of buffer spring 3 and be supported in buffer spring 3 and push up
The buffer board 13 in portion, the buffer board 13 is just to elevator car bottom 1；Basis 8 refers to the installation for Buffer Unit
Basis；As illustrated, being additionally provided with the basis of for installing the spring base 6 of buffer spring 3, can be used for the maximum for adjusting spring 3
Compression travel and limited compression position；The quantity of buffer spring 3 can be installed as needed, and generally more than three circumferentially
Direction is uniformly arranged；Can be installed with being merged into capable welding using lead column at the top of buffer board 13 and buffer spring 3, it is to avoid buffering or
Depart from during bounce-back.

Before, the piston rod 5 of damper assembly is depressed row, and damping piston 10 is had an effect to form damping, is collectively forming with buffer spring slow
Punching damping, the mode that piston rod 5 is engaged with buffer board is usually the way of contact, i.e. the descending directly contact piston rod upper end of buffer board
Portion, you can realize the effect of descending damping；As illustrated, on damping piston 10 have damping hole (be sized as needed and
Quantity), the damping liquid such as fluid or magnetic flow liquid is full of in cylinder body, when piston is moved under external force, damping liquid is only
Passed through by damping hole, form damping；As illustrated, cylinder body 9 is embedded among basis 8, top is sealed by cylinder cap 11, cylinder cap 11
Cylinder body 9 is sealedly attached to by the foundation bolt 7 being embedded on basis 8, is integrally formed on cylinder cap 11 for being oriented to piston rod
Axle sleeve 12；The structure combined with damper assembly using buffer spring, is bottomed out damper assembly in buffering course in elevator car and is connect
The effect of laddering buffer damping is closed, the structure can increase the cushion stroke of Buffer Unit and reduce the elastic coefficient,
The realization whole process buffering that more can be relaxed；The structure is suitable to all cage type elevators and uses, and when elevator accident is bottomed out, ensure that
Compression buffering that is gentle, gradually going forward one by one.
In the present embodiment, the buffer spring 3 is variable-pitch spring；Elevator car bottom out in buffering course damping force by
Cumulative big, and increase process is rapid and gentle compared with common spring, realizes the ride comfort of downstream buffer and with enough resistances
Buddhist nun's power, therefore can increase the coefficient of elasticity of cushion stroke and gradual change compared with prior art, can be formed automatic adjustment spring power this
The technical scheme of one critical performance parameters, be applicable to express elevator use, the effect with dynamic application at any time, combine with delay
Rush the relative damping structure for going forward one by one of spring so that elevator car 1 bottom out the comfortableness of the moment of front and contact Buffer Unit and
Reliability effectively improves, the security performance of hoisting elevator.
In the present embodiment, the pitch of the buffer spring 3 is become larger from bottom to top；Can be in the wink of the contact of elevator car 1
Between can submissive buffering at once, and gradually increase coefficient of elasticity.
In the present embodiment, relative with piston rod 5 be provided with the buffer board 13 by can axially directed in the way of be coated at
The fairlead 4 of piston rod 5, is provided with for the pedestal 2 with 5 tip contact of piston rod in the fairlead 4；Tied using fairlead 4
Structure, can limit the lateral orientation of buffer board 13 and piston rod 5, so as to realize effectively engagement damping.
In the present embodiment, the pedestal 2 is integrally formed with fairlead 4 and is fixedly installed on buffer board 13, and buffer board 13
Process for thickening at pedestal is fixedly installed；As illustrated, be formed down staircase structural model by buffer board, be followed successively by thickening layer,
Pedestal 2 and fairlead 4, the force structure according to damping form stable load basis, so as to be further ensured that buffer damping mistake
Safety in journey.
In the present embodiment, 13 upper surface of the buffer board, 5 upper surface of piston rod and 2 lower surface of pedestal are respectively provided with buffering
Layer；The cushion is prevented from direct rigid contact, so as to ensure safety and compliance.
In the present embodiment, the buffer spring 3 is installed on basis by the spring base 6 being fixed on basis 8, it is ensured that spring
Installation strength and the height of spring base can be changed as needed, reach the purpose of adjustment its length, so as to adjust compressed line
Journey.
Finally illustrate, above example is only unrestricted in order to technical scheme to be described, although with reference to compared with
Good embodiment has been described in detail to the present invention, it will be understood by those within the art that, can be to the skill of the present invention
