The driving device 7 may be an existing screw elevator (e.g., a worm screw elevator), and the structure belongs to the existing mature technology and is not described herein.
The structure can realize the rotation of the upper inner shaft 21 on one hand, thereby realizing the quick connection and disconnection with the lower inner shaft 22; on the other hand, the lifting of the inner shaft relative to the outer tube can be realized, so that the locking piece 4 is locked or released; to facilitate passage and carrying of the tie plate; on the other hand, the inner shaft and the outer pipe can be lifted synchronously, and the base plate can be driven to lift after the base plate is loaded, so that the base plate is laid or lifted and recycled conveniently.
After the plurality of base plate hoisting units are applied to the base plate hoisting tool, the base plates are convenient to bear and put down, and the base plates are locked and loosened to facilitate laying and recycling.
Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
