Abstract

The invention discloses a crane hoisting device. The device comprises an air cylinder, a sliding block, a triangular support, a first hoisting arm, a mast fixing frame, a pair of masts and a controller; a three-position five-way air cylinder is adopted as the air cylinder, the sliding block is connected to the top of a piston rod of the air cylinder, the sliding block is mounted in a guide groove in the bottom side of the first hoisting arm, and one end of each of the pair of masts is fixedly connected with the mast fixing frame; the mast fixing frame is mounted on the first hoisting arm; the first output end of the controller is connected with the first input end of an electromagnetic valve of the three-position five-way air cylinder, and the second output end of the controller is connected with the second input end of the electromagnetic valve of the three-position five-way air cylinder; and the invention further discloses a control method of the crane hoisting device.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a crane hoisting device and a control method thereof. Background technique [0002] As the crane gradually develops towards the direction of large tonnage, the main arm of the crane usually needs various auxiliary arms as auxiliary supports. The commonly used crane arm support device is based on the mast and is completed by pulling the additional wire rope. This kind of crane super-lift The installation of the device is inconvenient and the scope of application is small. The mast is installed on the boom through the door frame and is fixedly connected with the first boom. The stability of the hoisting of the whole vehicle increases the safety hazards in the use process and reduces the efficiency of the crane in the working process. [0003] In addition, when the crane is working, the angle between the boom and the ground will affect the specific force of the boom. At...
