Special lifting appliance for thin-wall cylindrical component

Abstract

The invention relates to a special lifting appliance for a thin-wall cylindrical component. The special lifting appliance comprises a screw rod, a driving piece, a positioning piece, a linkage piece, connecting rods, guide rails, sliding blocks and hanging clamps. The screw rod is vertically arranged, and the driving piece drives the screw rod to rotate. The screw rod is sequentially sleeved with the linkage piece and the positioning piece from top to bottom, and the positioning piece is in threaded connection with the screw rod. When the screw rod rotates, the positioning piece is driven to move upwards or downwards, and the positioning piece drives the linkage piece to move upwards synchronously or move downwards synchronously through the dead weight of the linkage piece. and the number of the guide rails is at least two, and the number of the sliding blocks, the number of the connecting rods and the number of the hanging clamps are consistent with the number of the guide rails. The guide rails are horizontally arranged, and the multiple guide rails are evenly arranged in the circumferential direction of the screw rod at intervals. Each guide rail is provided with one sliding block in a sliding manner, each sliding block is fixedly connected with one hanging clamp, and the hanging clamps are located below the sliding blocks. The ends, close to the screw rod, of the connecting rods are in rotation connection with the linkage piece, and the ends, away from the screw rod, of the connecting rods are rotationally connected with the sliding blocks. The special lifting appliance has the beneficial effects that when the special lifting appliance is used for hoisting the thin-wall cylindrical component, the roundness of the thin-wall cylindrical component can be constant, and the thin-wall cylindrical component can be conveniently clamped in the next station.

Description

technical field [0001] The invention relates to the technical field of slings, in particular to a special sling for thin-walled cylindrical components. Background technique [0002] Thin-walled cylindrical components need to be hoisted to the next station for clamping during processing. At present, the spreaders used for hoisting thin-walled cylindrical components are generally slings with a reverse clip type lifting tongs at both ends. During the lifting process, in order to facilitate the clamping of the next station, it is necessary to keep the roundness of the thin-walled cylindrical member constant. Wherein, the wall thickness of the thin-walled cylindrical member is 0.1-5 mm. [0003] In order to keep its roundness constant, it is necessary to ensure that the axis of the thin-walled cylindrical member coincides with the vertical centerline of the sling and the distance between the oppositely arranged anti-clip lifting clamps is constant during the hoisting process, s...

AI Technical Summary

Problems solved by technology

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a special hoist for thin-walled cylindrical components, which solves the problems of the existing slings with a reverse clip-type lifting tongs at both ends. The spreader cannot keep the axis of the thin-walled cylindrical member coincident with the vertical centerline of the sling and the distance between the opposite clamps is constant during the lifting process, resulting in the inability to keep the roundness of the thin-walled cylindrical member constant. It is convenient for the clamping of subsequent stations, and it needs multiple adjustments, which is a technical problem with low efficiency
