Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
The present apparatus includes walking guide rail 1, and as shown in Fig. 1-Fig. 7,1 upper end of walking guide rail is equipped with walking cylinder bracket 2,
Through the walking connection support piston shoes 4 of oil cylinder 3, the support piston shoes 4 include slip base 6, slip base 6 for the side of walking cylinder bracket 2
Upper end be equipped with Pressure Block 5, the inside lower end of the Pressure Block 5 is equipped with Pressure Block otic placode 10, and Pressure Block otic placode 10 is through jacking oil
Cylinder connection pin shaft 7 and the upper end of jacking cylinder 8 link, and the lower end of jacking cylinder 8 and the slip base of 6 inner top side of slip base jack
Oil cylinder otic placode 12 connects, and one end of the slip base 6 is additionally provided with the walking oil cylinder otic placode 11 connecting with walking oil cylinder 3, described to hold
The upper end of wedge 5 is connect through connecting flange 9 with top apparatus.
The bottom surface both side of the walking cylinder bracket 2 and slip base 6 is equipped with the anti-hook 13 of " C " type.
The Pressure Block 5 and slip base 6 are the box structure of one section of opening, and the two is in be mutually inserted formula cloth in open end
It sets, Pressure Block otic placode 10, jacking cylinder 8, slip base jacking cylinder otic placode 12 are arranged in box structure.
In the utility model, the support piston shoes 4 are placed in walking guide rail 1, Pressure Block 5 by connecting flange 9 with it is upper
Portion's equipment bolts, and the Pressure Block otic placode 10 inside Pressure Block 5 connect pin shaft 7 with jacking cylinder 8 with jacking cylinder and connects, jacking oil
The other end of cylinder 8 is connect with the slip base jacking cylinder otic placode 12 inside slip base 6, and 6 bottom of slip base is additionally provided with the anti-hook of " C " type
13, avoid support piston shoes 4 from skidding off walking guide rail 1 and lift rail during hauling guide rail 1；The support piston shoes 4
It is connect by the walking oil cylinder otic placode 11 on its slip base 6 with walking oil cylinder 3 with pin shaft, the other end for oil cylinder 3 of walking and walking
