The length at handle mounting groove two ends is identical with the length of the bottom end face of rack platform.Opening block slide rail 9
Being shaped as dovetail configuration, jacking block slide rail 10 is rectangular configuration.Jacking block slide rail 10 is vertically set on opening block
The lower end of slide rail 9, the front end of jacking block slide rail is corresponding with the middle part of opening block slide rail, jacking block slide rail 10
End is connected with handle mounting groove 11.
The top of handle 6 is arranged in handle mounting groove 11, is provided with and passes through for adjusting part in handle 6
The cavity 23 worn, is provided with boss on the internal face of cavity 23, thus forms gathering sill 12.This cavity
The size of top end face opening more than the size of its bottom end face opening.The top end face of handle and cavity
Top end face be same end face, the bottom end face of handle and the bottom end face of cavity are same end face.
Adjusting part uses bonded mode to be arranged in handle mounting groove 11, its front end and jacking block 5
End is connected.In the present embodiment, adjusting part by regulate bolt 8 and be set in outside it from
Lever 7 is constituted, and the female thread of follower lever is connected with the external screw thread of adjusting nut, the outside wall surface of follower lever 7
It is provided with the feather key 24 matched with gathering sill 12 in handle mounting groove 11.Due to feather key and guiding
Groove matches, so follower lever can only be for linear motion and can not circle.
Jacking block 5 is arranged on jacking block slide rail 10, and is arranged on the lower end of opening block 4, and jacking block is driven
Moving along a straight line in jacking block slide rail under the promotion of bar.Jacking block 5 by the top jacking block 14 being connected with
Bottom jacking block 15 is constituted, and is attached fixing by bolt.Wherein, the front end of top jacking block 14 sets
Having the point 13 for forcing opening block 4 to move to both sides, end is planar structure.Top jacking block 14
Lateral cross section be shaped as T-shaped structure, the longitudinal part in this T-shaped structure is arranged in jacking block slide rail, should
The bottom end face of longitudinal part is horizontal structure with the bottom end face of jacking block slide rail.
Opening block 4 is arranged on opening block slide rail 9, and its front end is provided with for inserting piston ring hasp gap
The insertion end 16 at place, its end is provided with the cone tank 17 inserted for point 13.Opening block 4 is by phase
The left opening block 18 that structure is identical and position is corresponding is constituted with right opening block 19, wherein, opens with a left side
As a example by buccal mass, left opening block 18 is made up of with lower-left opening block 21 the upper left opening block 20 being connected, and
It is attached fixing by bolt.The front end of upper left opening block 20 is provided with for inserting piston ring hasp gap
The left part at place, inner wall surface thereof includes left-leaning inclined-plane, the shape of lower-left opening block and opening block slide rail
Shape is identical, is dovetail configuration.Right opening block is by the upper right opening block being connected and bottom right opening block structure
Become, and be attached fixing by bolt.The front end of upper right opening block is provided with for inserting piston ring hasp
The right part of gap location, inner wall surface thereof includes Right deviation inclined-plane, and the shape of bottom right opening block is sliding with opening block
The shape of rail is identical.Left part contacts with right part and inserts end 16 to constitute, the "Left"-deviationist in left-leaning inclined-plane
Right deviation inclined-plane in Right deviation inclined-plane, the inclined-plane is to constitute the cone tank 17 inserted for point.
Jacking block moves to the position of opening block under the effect of follower lever, so that point inserts cone tank
In, left and right opening block forces left and right opening block to its two side shifting under the squeezing action of point.
The job step of the present invention is, is put into by rack body at the piston ring position needing to take out, dismounting
Personnel one only hold handle, allow support convex shoulder enter into the gap of piston ring and piston ring groove；Get out of the way
The end that inserts of buccal mass front end enters into the hasp gap location of piston ring, and now, operator are with other one
Hands rotates regulation bolt counterclockwise, and swivel bolt forces follower lever outward movment by the connection of screw thread, from
Lever promotes jacking block to move forward, and jacking block inserts the cone tank of opening block end by the point of its front end
In, force under the squeezing action of point left and right opening block to its two side shifting so that left and right
Opening block is separated position.Owing to the front end of opening block acts at the hasp of piston ring, force piston ring
Overcome the elastic force of self to open, when in rack body is encountered in the outer of piston ring along time stop regulation spiral shell
The rotation of bolt, now, a diameter of 300mm of piston, the minimum diameter of support convex shoulder is 305mm, this
Sample be just easy to piston ring together with support at piston that out, then regulation bolt turn clockwise,
Piston ring, by the elastic returning original state of self, is taken out at support.The dismantlement work of piston ring completes.
Only as described above, only presently preferred embodiments of the present invention, be such as familiar with the special of this skill
Industry personage. after understanding the technological means of the present invention, natural energy is according to actual needs, in the present invention
Teaching under changed.The most all equal changes made according to scope of the present invention patent and modification,
Once should still remain within the scope of the patent.
