At present, there are many kinds of hoist on the market, including spiral hoist, which is a large-scale lifting equipment that is transported by changing potential energy. The spiral hoist has a relatively strong lifting capacity and high power. It can transport crushed limestone and other massive materials, pulverized coal, cement raw materials and other powdery materials through vertical lifting, and can transport different types of materials according to different operating speeds.

Currently on the marketHoistThere are many kinds, including the spiral hoist, which is a large lifting equipment that is transported by changing the potential energy. The spiral hoist has a relatively strong lifting capacity and high power. It can transport crushed limestone and other massive materials, pulverized coal, cement raw materials and other powdery materials through vertical lifting, and can transport different types of materials according to different operating speeds.

At present, the spiral hoist and traction components include adhesive tape, plate chain and ring chain. The structure and manufacturing method of the ring chain are relatively simple, and the connection point between the ring island is quite firm. Therefore, in the process of conveying some relatively large materials, the chain is less worn, but its own weight is relatively large.

In the spiralHoistThe structure of the plate chain is also relatively firm, and its own weight is relatively light, which can be applied to a hoist with a relatively large amount of lifting, while the plate chain joint is easier to wear. The structure of the adhesive tape is relatively simple, but it cannot transport some relatively large materials, and the materials of the ordinary adhesive tape cannot exceed 60 ℃. The steel rope adhesive tape can transport materials with a temperature of up to 80 ℃, while the heat-resistant adhesive tape is allowed to carry materials above 120 ℃, while the materials that can be transported by the other two connection methods can have a temperature of up to 250 ℃.

The spiral hoist is composed of traction belt, hopper, roller, intermediate casing, braking device, driving device and other parts. It can transport some loose granular powder with relatively small density and small block materials, such as cement, crushed stone, sand, coal and so on.

InHoistThe reducer is directly installed on the spindle head, eliminating the need for transmission platforms, couplings, etc., making the structure compact and light in weight. And its internal with special-shaped roller backstop, backstop reliable. The reducer has low noise, stable operation, and floating with the spindle, which can eliminate the installation stress.

Spiral hoist is mainly used for conveying powder, granular and small block materials, chemicals, etc. Spiral hoist is not suitable for conveying perishable, viscous and caking materials. The rotating spiral blade transports the material, so that the material does not rotate with the spiral hoist blade. The force is the weight of the material itself and the frictional resistance of the spiral hoist casing to the material. The rotating shaft of the spiral hoist is welded with spiral blades, and the surface type of the blades includes solid surface type, belt surface type, blade surface type and other types according to the different conveying materials. The spiral shaft of the spiral hoist has a thrust bearing at the end of the material movement direction. When the spiral pipe is long, an intermediate hanging bearing should be added.
