Abstract

The invention discloses a counter weight mechanism and a crane, and relates to the technical field of engineering machinery. The counter weight mechanism provided by the invention comprises a telescopic rack body, a first telescopic mechanism, a second telescopic mechanism, a hanging piece and a counter weight, wherein the telescopic rack body comprises a fixed piece and a movable piece; the movable piece and the fixed piece are inserted into each other and can move relatively to each other; a first member of the first telescopic mechanism is fixedly connected with the fixed piece; a second member of the first telescopic mechanism and the movable piece are fixedly connected with a first member of the second telescopic mechanism, and the second member of the first telescopic mechanism can drive the movable piece and the first member of the second telescopic mechanism to at least move in a reciprocating mode horizontally; a second member of the second telescopic mechanism and the hanging piece are fixedly connected with each other or are in an integral structure; the second member of the second telescopic mechanism can drive the hanging piece to at least move in a reciprocating mode vertically; the hanging piece is connected with the counter weight in a hanged mode. According to the counter weight mechanism provided by the invention, the counter weight is conveniently mounted and detached.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a counterweight mechanism and a crane provided with the counterweight mechanism. Background technique [0002] At present, cranes have been widely used. The counterweight mechanism is one of the important components of the crane. [0003] During the operation of large-tonnage mobile cranes, especially truck-mounted cranes and truck cranes, the stability of the crane is an important factor to be considered in the design. Adding a balance weight (or called: counterweight) at the tail of the crane is a common method to increase stability. [0004] There are mainly two types of counterweight setting methods in the prior art: fixed counterweight and movable counterweight. Fixed counterweights are mostly used on conventional truck cranes. Due to structural and space constraints, they often play a limited role in increasing stability, and they are heavy, which increases ...
