In up big and down small T shape, upper part slideably covers on 32 other end of cross tube, the butterfly spiral shell being screwed into 331 top of sliding block
332 lower end of bolt is resisted against the upper side of cross tube 32, so that sliding block 331 is fixed on cross tube 32.32 other end of cross tube
Downside bonds one layer of rubber pad 321, and the rubber pad 321 of the present embodiment is with a thickness of 2mm, for avoiding on the downside of 32 other end of cross tube
It directly contacts 10 upper end port edge of cylinder sleeve and causes to scratch.
As shown in figure 3, the small end of cone rubber block 333 is embedded in 331 lower part of sliding block towards in the side of center sunpender 2, top
Tight screw 334 is screwed into sliding block lower part in 2 side of center sunpender, pushes 333 small end of cone rubber block towards 10 upper end of cylinder sleeve
Outer peripheral surface direction it is mobile so that the big end of cone rubber block 333 is resisted against on the outer peripheral surface of 10 upper end of cylinder sleeve, prevent cylinder sleeve 10
Run-off the straight deviates during lifting.
Limited block 5 positioned at the downside of balance rack assembly 3 pass across 2 lower part of center sunpender and with 2 lower vertical of center sunpender
It is welded and fixed.Limited block 5 is used to prevent balance rack assembly 3 in a non-operative state since self gravity slips down to extreme lower position,
It needs balance rack assembly 3 being promoted to operating position again when use, increases workload, the fixation position of limited block 5 should basis
The height of the minimum cylinder sleeve of required lifting determines that is, after the fixed support of minimum cylinder sleeve, the top surface of limited block 5 is slightly below cylinder sleeve
10 apical position.
Fixed transverse rod component 4 passes across the lower end for covering cylinder sleeve and 10 center sunpenders 2 outside the sunpender of center, solid with cylinder sleeve 10
Fixed connection.Fixed transverse rod component 4 includes fixed round tube 41 and 2 piece support pipe 42, under fixed 41 middle part of round tube and center sunpender 2
Vertical welding downlink connection is held, fixed 41 both ends inner wall of round tube is respectively equipped with oppositely oriented internal screw thread, 2 42 one end of support pipe point
She You not be with the matched external screw thread of corresponding internal screw thread, the end face of 42 other end of support pipe is vertical with baffle 43 to be fixedly connected；
42 outer diameter of support pipe is less than the cinclides 101 for traversing 10 lower part of cylinder sleeve, in order to which support pipe 42 passes through cinclides 101.
The handling method of diesel cylinder sleeve suspender the following steps are included:
1) center sunpender 2 is packed into cylinder sleeve 10
The center sunpender 2 being solidly fixed and fixed round tube 41 are lifted up into cylinder sleeve 10, seen from the cinclides 101 of 10 lower part of cylinder sleeve
It examines, when fixed round tube 41 reaches the position of cinclides 101, the cinclides 101 from 10 two sides of cylinder sleeve is outer by support pipe 42 1 respectively
End is injected in cylinder sleeve 10.Rotational support round tube 42 makes the external screw thread of 42 one end of support pipe and fixes the interior of 41 corresponding end of round tube
It is threadedly coupled integrally, until being abutted on 10 outer wall of cylinder sleeve of corresponding side on the inside of baffle 43.
2) it is packed into balance rack assembly 3
It will first be moved outside the cylinder sleeve outer circle support component 33 of 4 32 outer ends of cross tube of balance rack assembly 3, then by balance rack assembly
31 sets of 3 central rectangular casing on center sunpender 2, central rectangular casing 31 slowly falls together with 4 cross tubes 32, until 4
Rubber pad 334 on the downside of 32 other end of root cross tube is fallen in the upper end port of cylinder sleeve 10
3) cylinder sleeve outer circle support component 33 is resisted against on the outer peripheral surface of 10 upper end of cylinder sleeve
Each sliding block 331 is moved along respective cross tube 32 towards 2 direction of center sunpender, until the cone of each 331 lower part of sliding block
The big end end face of shape rubber block 333 is resisted against on 10 upper end outer peripheral surface of cylinder sleeve.Then the butterfly on each sliding block 331 is first tightened respectively
Bolt 332, the position of fixed sliding block 331, then the Top fastening screw 334 of each 331 lower part of sliding block is turned respectively, make each cone rubber block
333 big end end face is resisted against on the corresponding outer peripheral surface in 10 upper end of cylinder sleeve, completes the connection of diesel cylinder sleeve suspender and cylinder sleeve 10.
5) handling cylinder sleeve 10
By the lifting bolt and nut group 1 of 2 upper end of handling steel wire penetrating center sunpender, suspension hook, which rises, tenses handling wirerope, just
It can handling cylinder sleeve 10.
In addition to the implementation, the present invention can also have other embodiments, all to use equivalent substitution or equivalent transformation shape
At technical solution, be all fallen within the protection domain of application claims.
