Balance adjustment device for crane balance beam connection structure

Abstract

The invention discloses a balance adjustment device for a crane balance beam connection structure, comprising a balance beam and a fixing frame, a connection box is arranged above the balance beam, and a first connection pile is fixed on the upper surface of the connection box by bolts. The inner side of the connection box is provided with a connection ball, the lower surface of the connection ball is evenly welded with a support rod, the lower surface of the balance beam is welded with a fixing frame, and the outer surfaces of both sides of the connection box are welded with connection plates , the lower surface of the connecting plate is fixed with a first telescopic cylinder by bolts, the inner side of the first telescopic cylinder is provided with a first telescopic rod and a first piston, and the first piston is sleeved on the top end of the first telescopic rod The bottom end of the first telescopic rod is welded with a third connecting pile, and the bottom end of the third connecting pile is hinged with a fixed pile through a hinge shaft. The invention has an automatic balance adjustment structure, can automatically adjust the position of the balance weight after hoisting, and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of crane balance beams, in particular to a balance adjustment device for a crane balance beam connection structure. Background technique [0002] The balance beam is an important part of the crane. When lifting a large object, it is necessary to assemble the balance beam at the bottom of the spreader first, and then fix the large object on the balance beam, and lift the large object by lifting the balance beam. The balance beam is mainly used to keep the balance of the suspended equipment. [0003] The balance beam connection structure is a component installed on the balance beam, which is mainly divided into two types, one is installed at the center of the upper surface of the balance beam for connecting the spreader, and the other is installed at the bottom of the balance beam for For connecting hooks, the connecting structures installed at the bottom of the balance beam are usually arranged in groups and...
