Clamping mechanism for hoisting duct piece

Abstract

The invention discloses a clamping mechanism for hoisting a duct piece. The clamping mechanism comprises a cross beam, a first clamping mechanism and a second clamping mechanism, the first clamping mechanism and the second clamping mechanism are located on the two sides of the lower end of the cross beam correspondingly, a hanging ring is fixedly connected to the middle of the upper end of the cross beam, horizontally-parallel positioning threaded holes are formed in the middle positions of the outer surfaces of the front end and the rear end of the cross beam, positioning bolts are arranged in the threaded holes corresponding to the two groups in a penetrating mode, a clamping groove is formed in the outer surface of the lower end of the cross beam, and a fixing block is welded to the middle of the outer surface of the lower end of the cross beam. According to the clamping mechanism for hoisting the duct piece, the clamping angle of the clamping mechanism is accurately controlled, theclamping firmness is improved, the duct piece is prevented from being damaged, the clamping mechanism can be adjusted according to the segments with different specifications and sizes, the applicability is relatively high, the use is convenient, and the falling influence operation cannot be carried out in the using process of a line.

Description

technical field [0001] The invention relates to the field of clamping mechanisms, in particular to a clamping mechanism for segment hoisting. Background technique [0002] Segment is a kind of building material often used in the construction field, and it is often transferred by hoisting during the production and transportation process. The hoisting process requires the use of a clamping mechanism, which can clamp and fix the segment. [0003] However, some of the existing clamping mechanisms for segment hoisting use manual clamping, which is time-consuming and laborious. Others are not easy to control during the clamping process and are easy to damage the segment. Secondly, the different specifications of the segment often lead to different The use effect of the clamping mechanism brings certain troubles to the user. Finally, the circuit is easy to be dragged during use and affects the operation. Contents of the invention [0004] (1) Solved technical problems [0005] ...
