Clamping mechanism for hoisting of building construction site pipe

Abstract

The invention discloses a clamping mechanism for hoisting of a building construction site pipe. The clamping mechanism comprises a cross plate, mounting blocks, a supporting pipe, rotating shafts, first hinge seats and arc-shaped clamping plates, wherein second hinge seats are mounted on outer arc-shaped surfaces of the arc-shaped clamping plates; the ends, close to the mounting blocks, of the rotating shafts are provided with threaded parts; thread sleeves are mounted on the threaded parts; third hinge seats are mounted on the outer walls of the lower ends of the thread sleeves; and the thirdhinge seats are connected with the second hinge seats on the same side through connecting rods. According to the clamping mechanism, the lower ends of the connecting rods push the arc-shaped clampingplates to be close to each other, the two arc-shaped clamping plates clamp the pipe, and when the rotating shafts are reversely rotated, the clamped pipe can be released; and compared with traditional hydraulic control clamping operation, the clamping mechanism can be better controlled and is suitable for popularization and utilization.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a clamping mechanism for lifting pipes in a building construction site. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. [0003] We can see that there are many cranes on the construction site. These cranes are used to lift and unload the pipes. The traditional cranes are all practical hooks to lift the pipes.

Problems solved by technology

[0003] We can see that there are many cranes on the construction site. These cranes are used to lift and unload the pipes. The traditional cranes are all practical hooks to lift the pipes. In this way, workers are required to bind them when lifting. The operation is very troublesome. Later, a hydraulically driven clamping mechanism appeared. Although the hydraulic operation reduces the manpower, the entire lifting process requires hydraulic work throughout the whole process, so there is a lot of waste, so there is still a lot of use for this clamping mechanism. room for improvement
