Multifunctional electric hoist

Abstract

A multifunctional electric hoist disclosed in the invention comprises a multifunctional electric hoist body composed of a hoisting mechanism, a reduction gearbox, a lifting hook assembly and a switch controller, the left side of the hoisting mechanism is fixedly connected with the right side of the reduction gearbox, and the top of the lifting hook assembly is fixedly connected with the outer side of the reduction gearbox through a rotating seat; and the switch controller is located on the front side of the reduction gearbox, and the hoisting mechanism comprises a heat dissipation shell. The invention relates to the technical field of electric hoists. The multifunctional electric hoist can effectively solve the technical problems that in some flour processing factories, due to the fact that flour flies along with air and easily enters a hoisting motor, a hoisting motor body can generate a large amount of heat in the working process, the flour enters heat dissipation holes, the heat dissipation effect of the hoisting motor is affected, the service life of the hoisting engine is shortened, the hoisting engine automatically flames out under serious conditions, and potential safety hazards exist in the prior art.

Description

technical field [0001] The invention relates to the technical field of electric hoists, in particular to a multifunctional electric hoist. Background technique [0002] Miniature electric hoist is also called civilian electric hoist. Generally divided into fixed type and operating type, it is suitable for various occasions, and can lift goods below 1000 kg, especially suitable for lifting heavy items from downstairs in high-rise buildings. The structure is simple, the installation is convenient, small and exquisite, and single-phase electricity is used as the power source. The miniature electric hoist has reached the international standard in terms of production design, which ensures the safety of use. The motor cooling fin adopts cast iron structure, which improves the service life. The lifting speed of the miniature electric hoist can reach 10 meters per minute, and the length of the wire rope is initially designed to be 12 meters (extension can be customized). In terms ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides a multifunctional electric hoist, which can effectively solve the prior art. In some flour processing factories, since the flour flies with the air, it is easy to enter the hoisting motor, causing The heavy motor body will generate a lot of heat during the working process, and the flour will enter the cooling holes, which will affect the cooling effect of the lifting motor and reduce the service life of the lifting engine. In severe cases, the lifting engine will automatically turn off, posing a safety hazard question
