Abstract

The invention provides a locking mechanism for a cargo boom. The locking mechanism comprises a support, a work assembly and a drive assembly, wherein the support is used for being fixed on a basic armof the cargo boom, the work assembly is rotationally connected with the support, and the drive assembly is connected with the work assembly to drive the work assembly to rotate relative to the support so that the work assembly can be connected with or separated from a section arm of the cargo boom. According to the locking mechanism for the crane boom, the section arm can be locked in the advancing process of the automobile crane to prevent the section arm from moving, so that the safety of the automobile crane is guaranteed; and when the crane boom works, the section arm can be unlocked, andusing is convenient to achieve.

Description

technical field [0001] The invention relates to the technical field of truck cranes, in particular to a locking mechanism for a boom, a boom and a crane. Background technique [0002] At present, when the boom stops suddenly during the travel of the truck crane, the second-section boom often moves forward relative to the basic boom due to inertia, commonly known as "jump boom". The reason is that the second, third, fourth and fifth joint arms are connected to the basic arm through the oil cylinder. When the truck crane stops suddenly, the pressure provided by the hydraulic system cannot guarantee the locking of the oil cylinder, so the inertial force pulls the movement of the oil cylinder to cause the second, third, fourth, The five-section boom is stretched out, resulting in low safety of the truck crane. Contents of the invention [0003] The object of the present invention is to provide a locking mechanism for a boom, a boom and a crane, so as to solve the technical pr...
