A lifting fixture for tubular components

Abstract

The invention relates to the technical field of hoisting, and discloses a hoisting fixture for tubular components, comprising a first clamping arm and a second clamping arm hinged together; one end of the first clamping arm is provided with a first A lifting point, the opposite end is provided with a first clamping part, one end of the second clamping arm close to the first lifting point is provided with a second lifting point, and the opposite end is provided with a second Clamping portion; the first clamping portion and the second clamping portion form an accommodating space for tubular components. The hoisting fixture utilizes the weight of the tubular part itself to generate clamping force, realizes the convenient and stable grasping and lifting of the tubular workpiece, and has a simple structure, convenient operation and low cost.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a hoisting fixture for tubular components. Background technique [0002] Since the surface of tubular parts (such as exhaust pipes, transmission shafts, etc.) is arc-shaped, the contact surface with the spreader is small during the grabbing process, and it is easy to slide and rotate. Therefore, multi-point hanging or relying on external force is often used The clamping method is used for lifting and conveying. [0003] refer to figure 1 , is a schematic diagram of a multi-point hanging spreader used in the prior art. The top end of the spreader has a lifting hole 1', and the bottom end has two sets of hooks 2' arranged in parallel, and the pipe is placed in the hooks 2' for lifting. Although the sling can grab and lift the pipe, the workpiece may still be displaced and rotated in the radial or axial direction. The uncertain movement of the workpiece during the lifting and i...

AI Technical Summary

Problems solved by technology

The clamping spreader ensures the stability and accurate positioning of the workpiece during the grabbing process, but the structure is relatively complicated, the use cost is high, and the need for an external air source is not conducive to long-distance lifting

In addition, the weight of the structure in this solution is heavy and the clamping switch needs to be controlled, which is not easy to operate; the clamping force generated by the clamping claws is also difficult to determine. If it is too large, it will damage the workpiece, but if it is too small, it will easily slip.
