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.
