Hoister of shot blasting cleaning equipment

Abstract

The invention relates to a hoister of shot blasting cleaning equipment. The hoister comprises a case, a hoisting mechanism and recycling hoppers. The recycling hoppers are arranged on the case, the hoisting mechanism comprises a driving shaft, the driving shaft is penetratingly arranged on the case along the left-right directions, two ends of the driving shaft extend out of the case, the recyclinghoppers are arranged on the outer wall of the case and are positioned below the driving shaft, openings are formed in the upper portions of the recycling hoppers, the sides and the lower portions ofthe recycling hoppers are closed, straight slots which are perforated from the insides to the outsides are formed in the outer wall of the case and are particularly formed in the recycling hoppers, the recycling hoppers are communicated with the inside of the case via the straight slots, and the straight slots are used for leading steel shot in the recycling hoppers into the case. The hoister hasthe advantages that the recycling hoppers are arranged on the case and are positioned below the driving shaft, steel shot which leaks out from the case can be caught by the recycling hoppers and thencan be led back into the case by the straight slots, accordingly, steel shot leakage can be reduced to a great extent, the time for collecting steel shot falling onto the ground can be shortened for workers, and the labor intensity can be relieved; the steel shot collected by the recycling hoppers can return the case to be used, accordingly, wastage of the steel shot can be reduced, and the utilization rate of the steel shot can be increased.

Description

technical field [0001] The invention relates to a shot blasting cleaning device, in particular to a hoist for the shot blasting cleaning device. Background technique [0002] Shot blasting machine (shot blasting machine) is a shot blasting cleaning equipment that uses high-speed projectiles thrown by a shot blaster to clean or strengthen the surface of castings. The shot blasting machine can shake out sand, remove core and clean the casting at the same time. [0003] Shot blasting equipment is firstly used to remove sand and scale on the surface of cast steel and iron castings in the foundry industry. Almost all steel castings, gray castings, malleable steel parts, ductile iron parts, etc. must be shot blasted. This is not only to remove scale and sticky sand on the surface of castings, but also an indispensable preparation process before the quality inspection of castings. For example, the casing of a large gas turbine must undergo strict shot blasting before non-destruct...

AI Technical Summary

Problems solved by technology

After the current hoist is used for a period of time, due to the wear and tear of the parts, especially at the joint between the casing and the drive shaft, some steel grit will leak from the gap between the casing and the drive shaft, and thus be scattered on the hoist. On the outside ground, this not only increases the workload of workers to clean the ground, but also wastes steel grit
