Steel column is limited between inner cylinder and outer sleeve, and the vertical grafting of steel column, in order to its maintenance when It waits, it is easier to which the position being restored in inner cylinder if directly deviating from housing, does not only take up larger space, and is not easy to reply, separately On the one hand, by spring selected as memory alloy spring, purpose is also for the superpower restoring force using memorial alloy so that damping Afterwards, spring can accurately revert to initial state and position so that steel column smoothly divides spring when being inserted into inner cylinder.Shape is remembered The super elastic characteristics for recalling alloy have many advantages compared with other ordinary metallic materials：Super elastic shape memory alloy is tired first Labor characteristic is fine, and is inevitably damaged in other materials Xun Huan, influences the service life；Secondly marmem can recover Strain value is very big, what ordinary metallic material was difficult to realize；Finally, due to Ovshinsky bulk modulus is more than geneva bulk modulus, Shape memory alloy elastic modulus raises with temperature and increases (opposite with common metal), this makes it still keep at relatively high temperatures High elastic modulus.Therefore, the spring section of the device can be fabricated to using marmem.

The application method of the grading damper is as follows：

Two steel plates of first steel plate group 2-1 are slided along the inner wall of the second steel plate group 2-2, until chock 2-3 and the first steel plate group The chock 2-3 that the end contact of 2-1 is connected so that spring is compressed to make with spring is moved in accommodating hole, and chock 2-3 is with the first steel plate Group 2-1 is slided to be popped up up in the chock mounting hole 2-6 by the second steel plate group 2-2, and the first steel plate group 2-1 is fixed no longer sliding Dynamic, the fixing axle 2-14 is slided with the first steel plate group 2-1 on the first steel plate group 2-1, and in sliding process, is connected to it On " L " shape steel arm 2-11 gradually deform, and another " L " shape steel arm 11 connected to it is caused gradually to deform, should " L " shape steel arm 2-11 is deformed so that lifting arm 2-12 to be driven to be lifted up, and lifting arm 2-12 drives steel column 2-13 connected to it to be lifted up, and makes Divided spring connection；

Lifting arm 2-12 parallel to outer sleeve 2-8 and inner cylinder 2-9 side, steel column 2-13 be vertical grafting, lifting arm 2- 12 when being lifted up, and steel column 2-13 is driven to depart from the limit hole on inner cylinder 2-9, and in being limited in by the limit hole of outer sleeve 2-8 Between cylinder 2-9 and outer sleeve 2-8.

Chock 2-3 is squeezed, makes it by bouncing back in chock mounting hole 2-6, by the first steel plate group 2-1 along the second steel plate group 2-2 Inner wall is pulled outwardly cunning, and the fixing axle 2-14 on the first steel plate group 2-1 slides in and out with the first steel plate group 2-1, and in sliding process In, " L " shape steel arm 2-11 being connected thereto gradually is deformed, and another " L " shape steel arm 2-11 connected to it is caused gradually to become Shape is somebody's turn to do " L " shape steel arm 2-11 deformations to drive lifting arm 2-12 falls downwards, and lifting arm 2-12 drives steel column 2- connected to it 13 falls downwards, until steel column 2-13 spring 2-10 will be demarcated by the recess of spring 2-10 made of memorial alloy.
