Hoisting device for cement pipeline hoisting

Abstract

The invention relates to the technical field of hoisting devices, and discloses a hoisting device for cement pipeline hoisting. The hoisting device comprises a main body and a hoisting assembly, the outer wall of the top of the main body is movably connected with a steel cable, and the bottom of the right side of the steel cable is fixedly provided with a connector. According to hoisting device for cement pipeline hoisting, the cement pipeline is placed on a support plate. Then the steel cable is lifted, a mounting head and arc plates are tightened inward under the action of gravity, a connecting rod moves and a pneumatic rod shrinks, and meanwhile, a supporting assembly is folded inward, so that a limiting plate has a certain supporting force, and the supporting force acts on a supporting plate, so as to produce a certain supporting force for the cement pipeline; and then the two arc plates rotate towards the opposite sides and are inserted into extrusion heads, due to the fact that the extrusion heads are provided with mounting grooves, the extrusion heads can move downwards under the action of the arc plates, and meanwhile, the extrusion plates move downwards, extrusion force is generated on the cement pipeline, and then the effect that the cement pipeline bears uniform supporting force is achieved.

Description

technical field [0001] The invention relates to the technical field of lifting devices, in particular to a lifting device for lifting cement pipelines. Background technique [0002] Cement pipes, also known as cement pressure pipes and reinforced concrete pipes, are prefabricated pipes made of cement and steel bars and using the principle of centrifugal force of utility poles. Cement pipes can be used as sewer pipes in the foundation of urban construction, sewage, flood control and drainage, as well as upper water pipes and farmland wells used in some special factories and mines. With the development of society and the rapid progress of urban construction, the demand for cement pipes is increasing. It is also getting better and better. During the handling of cement pipelines, lifting equipment is often used. However, there are certain problems with traditional lifting equipment, which are mainly reflected as follows: [0003] 1. When the lifting equipment is in use, there i...

AI Technical Summary

Problems solved by technology

[0003] 1. When the lifting equipment is in use, there is often a lack of fixing devices, so during the lifting process, it is easy to cause the deviation of the cement pipeline, which will cause the cement pipeline to fall off and cause danger;

[0004] 2. When the lifting equipment is in use, the pressure and supporting force on the cement pipeline are often concentrated in one place, making the local pressure too high, causing it to be prone to rupture
