Abstract

The invention discloses an intelligent lock for a hoisting arm of a crane. The top end of the vehicle head is fixedly connected with bolts, the upper end of the locking mechanism is provided with a smart lock, the outside of the smart lock is provided with a limit frame, and the limit frame and the two locking plates on the locking mechanism are integrally formed, so The upper end of the locking plate is provided with a connecting plate, and there are two connecting plates. It realizes that when the safety officer issues a command to allow the crane to perform the lifting, the smart lock is turned on, and the boom can work. When the crane completes the lifting task, the boom is retracted and lowered, the smart lock locks the boom, and the status information of the smart lock is fed back. The system can effectively improve the safety factor of the hoisting arm of the crane and achieve the purpose of safe locking and use.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an intelligent lock for a crane arm. Background technique [0002] Crane is a kind of lifting and handling machinery widely used in ports, workshops, electric power, construction sites and other places. The name of the crane is the unified title of lifting machinery. Usually called cranes are mainly car cranes, crawler cranes and tire cranes. The usefulness of the crane lies in hoisting equipment, emergency rescue, lifting, machinery, and rescue. The crane mainly includes a lifting mechanism, an operating mechanism, a luffing mechanism, a slewing mechanism and a metal structure. The hoisting mechanism is the basic working mechanism of the crane, mostly composed of a suspension system and a winch, and also lifts heavy objects through a hydraulic system. The operating mechanism is used to move heavy objects vertically and horizontally or adjust the working position of the crane, ...
