Crane swing-relieving device adjustable in angle

Abstract

The invention discloses a crane swing-relieving device adjustable in angle. The crane swing-relieving device comprises a self-adjusted damping mechanism and a connection rod transmission mechanism. The self-adjusted damping mechanism comprises a combined clamping base, a damper and a spherical hinge, wherein the damper and the spherical hinge are installed in the combined clamping base in a clamped mode; the middle of the spherical hinge is provided with a channel; the combined clamping base comprises a left base body and a right base body which are matched; the upper end surface of the left base body and the upper end surface of the right base body are provided with lifting lugs corresponding to each other separately; a connection base is installed under the self-adjusted damping mechanism; a telescopic sleeve assembly is installed under the connection base; and the middle of the connection base is provided with a through hole. The connection rod transmission mechanism comprises a transmission rod; one end of the transmission rod is hinged to the combined clamping base, and the other end of the transmission rod is hinged to a slide base; and the slide base moves in the position, on the inner sides of the lifting lugs, of the lower end surface of a cantilever and is driven by an oil cylinder on one side of the slide base. According to the crane swing-relieving device adjustable in angle, on the one hand, normal conveying of a steel wire rope can be ensured, on the other hand, the load of the steel wire rope can be buffered, accordingly, the swing-relieving purpose is achieved, and balanced stress and stable operation of the whole machine in the process are ensured.

Description

[0001] Technical field: [0002] The invention relates to the field of cranes, and mainly relates to an angle-adjustable crane swing reducing device. [0003] Background technique: [0004] The crane has the advantages of flexible maneuvering, convenient operation and high efficiency. However, in the process of hoisting the operating object by the crane, the swing of the operating object has always been a problem that needs to be solved. [0005] In the process of material handling, traditional cranes usually use the reel on the electric hoist to lower the wire rope to hoist the hoisting materials. Since the wire rope is relatively soft, during the lifting process, factors from the outside or the operator's Improper operation methods will cause the lifting materials to shake in the front, back, left, and right directions, and collide with the surrounding machines or objects, causing some inevitable losses. If the swing is excessive and severe, the wire rope will also deviate, ...

Problems solved by technology

[0005] In the process of material handling, traditional cranes usually use the reel on the electric hoist to lower the wire rope to hoist the hoisting materials. Since the wire rope is relatively soft, during the lifting process, factors from the outside or the operator's Improper operation methods will cause the lifting materials to shake in the front, back, left, and right directions, and collide with the surrounding machines or objects, causing some inevitable losses. If the swing is excessive and severe, the wire rope will also deviate, and the materials will fall directly due to gravity. It affects normal use, and when hoisting and positioning, if the hoisting material shakes, it cannot be positioned quickly and accurately, which reduces work efficiency; Pendulum is very necessary
