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 buffer limit block is wear-resisting buffer rubber pad.
Further, the level-one spring is at least 2, and the level-one spring is evenly distributed on the buffering and rams and institute It states between buffering flat plates.
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 multi-buffer, including buffering 1, level-one spring of raming 2nd, buffering flat plates 3, two-level spring 4, piston rod 5, buffer limit block 6, hydraulic cylinder body 7, cylinder sleeve 8, cylinder cap 9, kickboard 10, heating Pipe 11 and pedestal 12.
Hydraulic cylinder body 7 is fixed on pedestal 12, and cylinder sleeve 8 is set in 7 periphery of hydraulic cylinder body, cylinder sleeve 8 and hydraulic pressure Cylinder cylinder body 7 forms cavity 13, and 13 top of cavity is equipped with cylinder cap 9, and buffer limit block 6 is arranged on cylinder cap 9, is set on cylinder sleeve 8 There are multiple throttle orifices 14, kickboard 10 is arranged in 7 inner cavity of hydraulic cylinder body, and 5 one end of piston rod is fixedly mounted in kickboard 10, separately One end and buffering, which are ramed, 1 to be fixedly connected, and the fixation of buffering flat plates 3 is set on piston rod 5, and is ramed 1 and cylinder cap 9 positioned at buffering Between, the setting buffering of level-one spring 2 is ramed between 1 and buffering flat plates 3, two-level spring 4 be set in buffering flat plates 3 and kickboard 10 it Between 5 periphery of piston rod.
7 inner cavity of hydraulic cylinder body is divided into air chamber 15 and oil pocket 16 by kickboard 10, and heating tube 11 is arranged in oil pocket 16.Add Heat pipe 11 is used to heat the fluid in hydraulic cylinder body, and hydraulic oil condenses when temperature can be prevented too low, influences buffering effect.
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 17, cylindrical sidewall 18 and seal base 19, and sheath top plate 17, which is mounted on, buffers 1 upper end of raming, tubular Side wall 18 is mounted on 17 lower surface of sheath top plate, and seal base 19 is mounted on the lower end of cylindrical sidewall 18.
The diameter of sheath top plate 17 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 18 is less than the design compression travel of buffer.
Buffer limit block 6 is wear-resisting buffer rubber pad.
Level-one spring 2 is at least 2, and level-one spring 2 is evenly distributed on buffering and rams between 1 and buffering flat plates 3.
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 makes Piston rod 5 moves down, and two-level spring 4 compresses and kickboard 10 is driven to move down, and oil pressure drastically increases in oil pocket 16 at this time, oil pocket 16 Interior fluid is flowed into from throttle orifice 14 in the cavity 13 between hydraulic cylinder body 7 and cylinder sleeve 8 under the action of kickboard 10, due to The metering function of throttle orifice 14, the speed of piston rod 5 are limited, and when buffering flat plates 3 drop to buffer limit block 6, buffering is hit First 1 compression level-one spring plays the effect of secondary buffer.
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.
