Above-mentioned elimination hoisting crane base beam connects the device in gap with track frame, wherein:
Described top shoe inclined-plane is downward, with the applying of sliding mutually of the inclined-plane of sliding block.
Above-mentioned elimination hoisting crane base beam connects the device in gap with track frame, wherein:
Be free-running fit slidably between the inwall of described top shoe side and cavity.
Above-mentioned elimination hoisting crane base beam connects the device in gap with track frame, wherein:
The end face of described hoisting crane base beam is provided with aperture; Described aperture is coaxial with the tapped bore of sliding block.
Above-mentioned elimination hoisting crane base beam connects the device in gap with track frame, wherein:
The aperture that described bolt passes hoisting crane base beam end face connects with the screw of sliding block.
Above-mentioned elimination hoisting crane base beam connects the device in gap with track frame, wherein:
The applying of sliding mutually of the bottom surface of described sliding block and the bottom surface of cavity cooperates for glade plane space between the inwall of two sides and cavity.
The utility model is owing to adopted above-mentioned technology, and the good effect that makes it compared with prior art to have is:
1, the utility model is eliminated the hoisting crane base beam connects the device in gap with track frame top shoe and sliding block and is fitted with incline plane type, changes the bottom-to-top-height of two slide block vertical direction by the relative position that changes two slide block horizontal directions.
2, the utility model is eliminated the hoisting crane base beam connects the gap with track frame device and is changed horizontal direction relative position between two slide blocks by the screw thread pair mode, thereby changes the bottom-to-top-height of two slide blocks, and then thoroughly eliminates the gap.
3, the utility model is eliminated between the last plane of the top shoe end face of hoisting crane base beam and the device in track frame connection gap and base beam and track frame connection holes and is contacted with the face laminating type, can thoroughly eliminate the gap effectively.
4, the utility model is eliminated the hoisting crane base beam connects the device in gap with track frame top shoe and sliding block, is hidden in the cavity of base beam, does not influence the function and the outward appearance of base beam.
