Abstract

The invention discloses a suction cup device and a crane. The suction cup device comprises a contactor, an electric motor, a winder, a suction cup hanger, a vacuum pump, a pressure detector, a first relay and a pressure alarm, when a material needs to be hoisted, the contactor and the corresponding power supply are communicated by an operator, so that the contactor is communicated with the electric motor to start the electric motor; the electric motor is started to control the vacuum pump to suck air from inside of the suction cup hanger to enable a suction cup to be vacuumized and form pressure; and the pressure detector detects pressure in an air flowing loop of the suction cup hanger, when the pressure value reaches the setting value, the pressure detector is communicated with the first relay and the pressure alarm, and the pressure alarm performs alarming operation to indicate the suction cup hanger to be in a working state, and then the operator can control a crane carriage to hoist the material, the operation is labor-saving and the efficiency is improved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a suction cup device and a crane. Background technique [0002] Cranes, also known as overhead cranes, are widely used in indoor and outdoor warehouses, workshops, docks, and open-air storage yards. They are usually equipped with lifting trolleys, and the lifting trolleys are composed of a lifting mechanism, a trolley operating mechanism and a trolley. The frame consists of three parts. Wherein, the lifting mechanism includes a motor, a brake, a reducer, a reel and a pulley block, and the operator operates the motor to drive the reel to rotate through the reducer to realize the lifting of the material. [0003] However, the inventor found in the research process of the present application that when using the crane of the prior art to lift items, when the material to be lifted is heavy, the operator needs to spend a lot of power and the efficiency is low. Contents of the invention [00...
