Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a supporting base for a construction crane includes a telescopic arm 1, a limit sleeve 2 is bolted to a telescopic end of the telescopic arm 1, a supporting tube 3 is bolted to an inner portion of the limit sleeve 2, a first bearing 4 is bolted to a top portion of the supporting tube 3, a screw 5 is sleeved to an inner portion of the first bearing 4, a partition plate 6 is bolted to an inner portion of the supporting tube 3, a second bearing 7 is bolted to a top portion of the partition plate 6, an inner portion of the second bearing 7 is sleeved to the screw 5, a threaded block 8 is screwed to a surface of the screw 5, first hinge parts 9 are bolted to both sides, front and back of the threaded block 8, a connecting rod 10 is hinged to an inner portion of the first hinge part 9, a second hinge part 11 is hinged to the other end of the connecting rod 10, a limit plate 12 is bolted to a bottom portion of the second hinge part 11, a side of the limit plate 12 is bolted to a third hinge part 13, and one.

Furthermore, the top of the screw rod 5 is bolted with a rotating handle 14, and the screw rod 5 can be conveniently rotated by a user through the rotating handle 14.
