Problems solved by technology

[0004] This solution solves the problem that the traditional crane counterweight is inconvenient to be fixed on the bottom of the crane during the installation process due to the heavy weight of the crane. At the same time, when the crane starts to work and lift, the crane counterweight is affected by gravity and centrifugal force It is easy to fall off and cause damage to surrounding people and buildings

Abstract

The invention relates to a crane counterweight structure and a stabilizing method. The crane counterweight structure comprises a counterweight block, fixing mechanisms are arranged at the two ends of the top face of the counterweight block, clamping blocks are arranged between the two fixing mechanisms and an external crane, and four connecting mechanisms corresponding to one another in position are arranged in the middle of the top face of the counterweight block and at the bottom of an external crane. Through mutual clamping of openings of two corresponding shells and cooperation with contraction of a tension spring, two rotating blocks are connected with corresponding rotating grooves in a clamped mode, the two connecting mechanisms corresponding in position are relatively fixed, the follow-up positioning effect needed by an installation plate and a block body is facilitated, the time needed by clamping of the installation plate and the block body is shortened; and a first limiting rod and a second limiting rod movably penetrate through the ends of a first connecting rod and a second connecting rod, an inclined block is pushed to a first baffle, the first limiting rod is supported by the inclined block, the first limiting rod and the second limiting rod are prevented from falling off, and therefore the stability of the counterweight block is improved.

Description

technical field [0001] The invention relates to the field of crane counterweights, in particular to a crane counterweight structure, and more specifically to a crane counterweight structure and a stabilizing method. Background technique [0002] The stability of the whole crane is one of the key indicators affecting the hoisting performance of the crane. Therefore, when designing the crane, the weight of the counterweight is often increased to the limit that the axle can carry to maximize the stability of the whole machine. . [0003] Due to the heavy crane counterweight, it is inconvenient to fix the traditional crane counterweight on the bottom of the crane during installation. At the same time, when the crane starts to work and lift, the crane counterweight is affected by gravity and centrifugal force, which is prone to Falling off causes damage to surrounding people and buildings. Contents of the invention [0004] This solution solves the problem that the traditiona...
