Universal hoisting clamp for circular tube

Abstract

The invention discloses a universal hoisting clamp for a circular tube. The universal hoisting clamp comprises a clamp, a base, a reducing motor mounted at the right end of the base, a left screw rod and a right screw rod, which are mounted in the base, and a saddle seat, wherein claws are mounted on the left screw rod and the right screw rod through threads, a groove is formed in the saddle seat, the tail ends of the claws are shaped like hooks and articulated with the groove formed at the upper part of the saddle seat, the top end of the clamp is articulated with a push rod, the top end of the push rod is articulated with the top end of the saddle seat, and the 1/3 part at the upper end of the clamp is articulated with the tail end of the saddle seat. The fastening by the clamp is adopted for replacing the conventional fastening by a steel wire rope, the clamping and the fixing against barrel pieces with different diameters can be realized, the structure is simple, and the range of applications is wide; and the claws driven by self-locking threads are used for fastening, automatic unlocking can be avoided, the operation is safe and reliable, and the surfaces of the barrel pieces can not be damaged due to friction during the hoisting process after being wound with the steel wire rope.

Description

technical field [0001] The invention relates to the technical field of hoisting of heavy objects, in particular to a round pipe universal hoisting fixture. Background technique [0002] In the technical field of heavy object hoisting, the hoisting of cylindrical objects, especially horizontal hoisting, often occurs. At present, there is no special lifting device. The previous solution is mainly: after the cylindrical objects are wound and tightened by steel wire ropes, they are connected. Hoisting on the spreader, the hoisting method has poor stress conditions, cumbersome and time-consuming operation process, insufficient safety performance, and poor versatility. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a universal hoisting fixture for round pipes, which is specially designed for hoisting cylindrical barrels. It adopts clamp-type fixed hoisting instead of traditional wire rope fixing. The operation pr...
