Intelligent lock of crane hoisting arm

Abstract

The invention discloses a intelligent lock of a crane hoisting arm. The intelligent lock of the crane hoisting arm comprises a crane body, the hoisting arm is arranged at the upper end of the crane body, a lock catch mechanism is arranged on the outer part of the hoisting arm and fixedly connected with the top end of a head of the crane body through bolts, an intelligent lock body is arranged at the upper end of the lock catch mechanism, a limiting frame is arranged on the outer part of the intelligent lock body, the limiting frame and locking buckle plates on the lock catch mechanism are arranged in an integrally-formed mode, and two connecting plates are arranged at the upper ends of the locking buckle plates. According to the intelligent lock of the crane hoisting arm, the intelligent lock body is unlocked and the hoisting arm can work after a safety worker sends a hoisting instruction allowing a crane to execute, after the crane finishes a hoisting task, the hoisting arm retracts and falls down, and the intelligent lock body locks the hoisting arm and feeds back the state information of the intelligent lock body to a system, so that the safety coefficient of the crane hoistingarm is effectively improved, and the purpose of safe locking and use is achieved.

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, ...

Problems solved by technology

[0003] The existing crane arm lacks an effective safety locking mechanism during use, which causes the arm to loosen easily when the crane is moving, which affects the safety factor of the crane arm. For this reason, we provide a crane arm smart Lock
