There are gaps between face.Then claw 32 is removed, to away from the horizontal slowly mobile travelling crane hook B7 in connecting rod direction, makes a pair of of arc
Clamp ring 31 loads onto the both ends that claw 32 holds bearing shell 30 towards the outside for being laterally moved to bearing shell 30 away from connecting rod direction.A small amount of lifting
Bearing shell 30 is simultaneously traversing to connecting rod direction, moves bearing shell 30 gradually traversing into connecting rod tip 20.Pay attention to whole process intermediate bushing 30
Exterior arc surface 301 and the inner arc surface 201 of connecting rod tip 20 be unable to contact-impact.Repetition removes the mobile traveling crane of claw 32-
Hook B7 make a pair of of arc clamp ring 31 it is traversing-process of loading onto the mobile travelling crane hook B7 of claw 32-keeps bearing shell 30 traversing, until axis
2/3 or more of watt 30 width enters in the inner arc surface 201 of connecting rod tip 20.Then it dismantles bearing shell suspender 3, then manually adjusts axis
Watt 30 positions, until entire bearing shell 30 is completely into connecting rod tip 20,30 both ends of the surface of bearing shell and 20 two sides of connecting rod tip are flat
Together, there are no the inner arc surfaces 201 of top connecting rod tip 20 for the exterior arc surface 301 of bearing shell 30 at this time.
6) bearing shell 30 is installed in place
On 4 lifting bolts 26 that the lower end suspension hook of lower tackles 5 is hung over to two 24 both ends of cross bar respectively, and will under
The upper end suspension hook of tackles 5 is all suspended on travelling crane hook B7, is adjusted the length of corresponding lower tackles 5, is made two cross
Bar 24 and supporting block 22 thereon are adjusted to horizontality.Rising simultaneously and mobile travelling crane hook A6 and travelling crane hook B7, make to connect
Bar and connecting rod tip lifting and bearing shell supporting mechanism 2 are lifted to the height that operator can be operated under it.Then it drives a vehicle
Suspension hook A6 is motionless, and travelling crane hook B7 slowly rises, while tightening the nut 232 on the load-bearing bolts 231 of connecting rod tip two sides, will
Bearing shell 30 moves the inner arc surface 201 for moving closer to connecting rod tip 20 from the bottom up, until the exterior arc surface 301 of bearing shell 30 and company
The inner arc surface 201 of bar big end 20 is bonded.Then as shown in figure 4, respectively determining bearing shell from the recess 223 of two pieces of supporting blocks 22
Position screw 8 is screwed into upward in the port plane of 20 two sides of connecting rod tip under, is fixedly connected with bearing shell 30 with connecting rod, to complete
The installation of bearing shell 30.
In addition to the implementation, the utility model can also have other embodiments, all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, is all fallen in the protection scope of the requires of the utility model.
