Large-diameter pipe joint hoisting fixture

Abstract

The large-diameter pipe joint hoisting clamp comprises an equal-thickness clamp body made of steel plates, the clamp body is integrally in a U shape, the clamp body comprises a bottom plate, a hoisting plate and a supporting plate which are integrally arranged, the hoisting plate and the supporting plate are perpendicularly arranged at the two ends of the bottom plate respectively, a hoisting hole is formed in the hoisting plate, and the supporting plate is provided with a clamping hole. A reinforcing plate is obliquely arranged and welded to the top end of the supporting plate, the reinforcing plate inclines towards the inner side of the supporting plate from top to bottom, and the width of the reinforcing plate is larger than the thickness of the supporting plate. And the large-diameter pipe joint is hoisted by taking the upper surface of the reinforcing plate as a supporting surface and taking the upper surface of the bottom plate as a supporting point. The fixture is simple in structure and convenient to assemble and disassemble, the large-diameter pipe joint with the wall thickness larger than or equal to 150 mm can be rapidly and reliably hoisted, the hoisting problem of the large-diameter pipe joint is effectively solved, and the on-site assembling and disassembling efficiency of the large-diameter pipe joint is improved.

Description

technical field [0001] The invention relates to a hoisting fixture, in particular to a large-diameter pipe section hoisting fixture. Background technique [0002] When large-diameter water supply and drainage concrete pipe joints or pipes (pipe diameter ≥ 2000mm, wall thickness ≥ 150mm, weight of tens of tons) are not provided with lifting points, when the manufacturer transports them to the site for installation, in the process of loading and unloading, generally use The wire rope is hoisted and unloaded by passing through the pipe section or winding the outside of the pipe section. In order for the steel wire rope to pass through the pipe section, it is necessary to set a spacer block under the pipe section, but this will cause problems such as unstable storage of the steel pipe, large floor space, and low hoisting and unloading efficiency. However, the method of setting temporary lifting points on concrete pipe joints or pipes is time-consuming and labor-intensive, and t...

AI Technical Summary

Problems solved by technology

In order for the steel wire rope to pass through the pipe joint, it is necessary to set up a pad under the pipe joint, but this will cause problems such as unstable storage of the steel pipe, large floor space, and low efficiency of hoisting and loading and unloading.

However, the method of setting temporary lifting points on concrete pipe joints or pipes is time-consuming and labor-intensive, and the comprehensive benefits are not obvious
