Problems solved by technology
[0003] When using the wire rope in windy weather, the wire rope must be lubricated frequently. It is best to use high-viscosity grease to reduce or reduce the wear of the wire rope and the pulley groove and the drum groove; Grease is often stained with soil, stone sand, etc. These objects on the surface of the wire rope will intensify the wear of the wire rope and the wheel groove, and the surface of the wire rope will be rubbed by mud, stone sand, etc., causing damage to the surface of the wire rope.

The invention relates to the field of electric hoists, in particular to an electric hoist for a single girder crane, including a driving mechanism, a fixing cylinder, a lifting mechanism, a fixing mechanism, a closing mechanism, a lubricating mechanism and a dust removal mechanism; the lifting mechanism is inside the closing mechanism When rotating, the lifting mechanism drives the lubricating mechanism to rotate, so that the lubricating oil inside the lubricating mechanism is evenly applied to the side wall of the lifting mechanism. rust; when the lifting mechanism slides out from the inside of the fixed cylinder, the lifting mechanism slides downward inside the lubricating mechanism and the closing mechanism, and the lubricating oil is coated on the side wall of the lifting mechanism to reduce the friction force when the lifting mechanism moves, and the lifting The mechanism slides down inside the dust removal mechanism, and the dust removal mechanism wipes off the excess lubricating oil on the surface of the lifting mechanism to avoid excessive dust on the surface of the lifting mechanism, thereby preventing a large amount of dust and sand from being adsorbed on the side wall of the lifting mechanism.
Description
technical field [0001] The invention relates to the field of electric hoists, in particular to an electric hoist for single beam cranes. Background technique [0002] Electric hoist is a kind of special lifting equipment, which is installed on the crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage, docks and other places. [0003] When using the wire rope in windy weather, the wire rope must be lubricated frequently. It is best to use high-viscosity grease to reduce or reduce the wear of the wire rope and the pulley groove and the drum groove; Grease is often stained with soil, stone sand, etc. These objects on the surface of the wire rope will intensify the wear of the wire rope and the wheel groove, and the surface of the wire rope will be rubbed by mud, stone sand, etc., causing damage to the surface of the wire rope.
