It states hydraulic cylinder body to be fixed on the pedestal, the kickboard is arranged in the hydraulic cylinder intracoelomic cavity, the kickboard
On be provided with throttle orifice, the boss is fixed at the lower surface for buffering and raming, and described piston rod one end is fixedly mounted
In the kickboard, the other end is fixedly connected with the boss, and the cushion pad is fixed at the hydraulic cylinder body upper table
Face, the secondary spring are set on the piston rod between the boss and the cushion pad, and the compressed spring is set in institute
It states on boss, and the compressed spring is arranged on the buffering and rams between the cushion pad.
Further, cylindrical case has been further included, the cylindrical case includes sheath top plate, cylindrical sidewall and sealing bottom
Plate, the sheath top plate buffer upper end of raming mounted on described, and the cylindrical sidewall is mounted on the sheath top plate lower surface,
The seal base is mounted on the lower end of the cylindrical sidewall.
Further, the diameter of the sheath top plate is more than the diameter for buffering and raming.
Further, the length of the cylindrical sidewall is less than the design compression travel of buffer.
Further, the secondary spring and the compressed spring hand of spiral are opposite.
Further, the throttle orifice number at least two, and be evenly arranged in the kickboard.
Further, the cushion pad is wear-resisting buffer rubber pad.
The utility model has the advantages and positive effects of：Due to the adoption of the above technical scheme, it can effectively improve
Cushion performance and operation stability, can be to avoid the pollution of dust and water to buffer, so as to protect by the cylindrical case added
Buffer has been protected, has reduced maintenance cost and maintenance difficulties.

Specific embodiment
The utility model is described further with reference to embodiment and attached drawing.
As shown in Figure 1, the present embodiment provides a kind of buffer of elevator of high resiliency, ram 1, boss 2, auxiliary including buffering
Help spring 3, compressed spring 4, piston rod 5, cushion pad 6, hydraulic cylinder body 7, kickboard 8 and pedestal 9.
Hydraulic cylinder body 7 is fixed on pedestal 9, and kickboard 8 is arranged in 7 inner cavity of hydraulic cylinder body, is set in kickboard 8
Have a throttle orifice 10, boss 2 be fixed at buffering ram 1 lower surface, 5 one end of piston rod is fixedly mounted in kickboard 8, another
End is fixedly connected with boss 2, and cushion pad 6 is fixed at 7 upper surface of hydraulic cylinder body, and cushion pad 6 can increase entire buffer
Flexible buffer.Secondary spring 3 is set on the piston rod 5 between boss 2 and cushion pad 6, and compressed spring 4 is set in boss 2
On, and compressed spring 4 is arranged on buffering and rams between 1 and cushion pad 6, and the design of boss 2 consolidates 4 installation site of compressed spring
It is fixed, 4 installation site translocation phenomenon of compressed spring can be avoided.
In order to avoid the pollution of dust and water to buffer, so as to protect buffer, cylindrical case, tubular have been further included
Shell includes sheath top plate 11, cylindrical sidewall 12 and seal base 13, and sheath top plate 11, which is mounted on, buffers 1 upper end of raming, tubular
Side wall 12 is mounted on 11 lower surface of sheath top plate, and seal base 13 is mounted on the lower end of cylindrical sidewall 12.
The diameter of sheath top plate 11 be more than buffering ram 1 diameter.Increase the contact area of car and buffer, buffering effect
Fruit is more preferable.
The length of cylindrical sidewall 12 is less than the design compression travel of buffer.
Secondary spring 3 is opposite with 4 hand of spiral of compressed spring.For buffer after being impacted, buffering rams 1 to cushion pad
6 directions are mobile and squeeze compressed spring 4, and at the same time secondary spring 3 is also compressed, 4 spiral side of secondary spring 3 and compressed spring
To opposite vertical and straight movement during 1 movement so that buffering is ramed, buffering is avoided to ram 1 because of 4 hand of spiral of secondary spring 3 and compressed spring
And rotate, ensure the working performance of buffer, and be reversed can be more for secondary spring 3 and 4 hand of spiral of compressed spring
Good plays cushioning effect.
10 numbers at least two of throttle orifice, and be evenly arranged in kickboard 8.It can ensure the fluid in hydraulic cylinder body
Uniform Flow makes its stress evenly.
Cushion pad 6 is wear-resisting buffer rubber pad.
The course of work of this example：When the sheath top plate 17 of car collision cylindrical case, buffering, which is ramed, 1 to be depressed, and delays
It is mobile to 6 direction of cushion pad and squeeze compressed spring 4 to collide head 1, at the same time secondary spring 3 is also compressed, make piston rod 5 to
Lower mobile drive kickboard 10 moves down, and oil pressure drastically increases in hydraulic cylinder body at this time, and the fluid in hydraulic cylinder body 7 is in kickboard 10
Under the action of, 7 epicoele of hydraulic cylinder body is flowed into from throttle orifice 14, due to the metering function of throttle orifice 14, the speed quilt of piston rod 5
Limitation, plays cushioning effect.
The beneficial effects of the utility model are：Due to the adoption of the above technical scheme, can effectively improve cushion performance and
Operation stability, by the cylindrical case that adds can to avoid the pollution of dust and water to buffer, so as to protect buffer,
Reduce maintenance cost and maintenance difficulties.
One or more embodiments of the utility model are described in detail above, but the content is only this practicality
Novel preferred embodiment, it is impossible to be construed as limiting the scope of the utility model.It is all according to present utility model application model
Made all the changes and improvements etc. are enclosed, should all still be belonged within the patent covering scope of the utility model.
