Abstract

The invention relates to the technical field of an internal expansion clamp for lifting hollow objects, and in particular, discloses a vertical cylinder lifting fixture. The vertical cylinder lifting fixture comprises a base and a pull rod, and further comprises a cam and two slide blocks; the two slide blocks are oppositely arranged and slidingly connected to the base; the cam is rotationally connected to the base and positioned between the two slide blocks; the rotational connectin part of the cam and the base is connected with a first torsion spring; multiple belt wheels are uniformly arranged and connected to the slide blocks; winding drums are connected to the lower sides of the belt wheels, and are connected with belts; the belts are matched on the outer sides of all the belt wheels; one ends, far from the winding drums, of the belts are fixedly connected to the cam; the parts, connected with the base, of the winding drums are connected with second torsion springs; an electromagnet is mounted on the base; and permanent magnets are connected to the inner sides of the slide blocks. The belts slide to pull the cam to rotate, and the slide blocks are driven to tension so as to make up the gap difference caused by micro deformation of a cylinder; and the clamping force of the fixture to the inner wall of the cylinder is automatically increased to improve the clamping stability of the fixture.

Description

technical field [0001] The invention relates to the technical field of internal tension clamps used for hoisting hollow objects. Background technique [0002] At present, the vertical hoisting operation of heavy-duty cylinders is mainly hoisted by wire rope winding and fixing, and there is no special fixture, so there are problems such as poor stress conditions, cumbersome operation process, and difficult guarantee of safety. In order to solve the above problems, Chinese patent CN104909261B discloses A heavy-duty cylinder vertical hoisting fixture. During the hoisting process of the cylinder, the electromagnet is energized to attract the armature and combine with the electromagnet. The tool side enters the inside of the barrel, and when the electromagnet is powered off, the spring resets, so that the friction block expands outwards and is clamped on the inner wall of the barrel. When the suspension rod is pulled, the pressure of the friction block is further increased due to...
