Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a vertical bucket type lifting mechanism. Background Art

[0002] Bucket elevator is a continuous conveying machine that uses a series of buckets evenly fixed on an endless traction member to lift materials vertically. Bucket elevator uses a series of buckets fixed on a traction chain or belt to transport bulk materials upward in a vertical or nearly vertical direction. It is divided into three types: chain, plate chain and belt.

[0003] Traditional belt hoists use overlapping screws to connect the belts. Since the thickness of the overlapping belt is twice the thickness of the belt, the overlapping belt will be stretched every time it passes through the active roller and the driven roller during operation, accompanied by obvious noise. Continuous stretching will cause the belt to stretch and deform too quickly, so it is necessary to manually adjust the tensioning mechanism frequently. Once the belt reaches the tension limit, it needs to be replaced in time. Noise is also a problem, especially when the running speed is fast, the noise is more obvious. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The belt connection method has been improved, and the flanged and pressed connection method has been adopted. The secondary connection method has ensured the continuity of the inner ring of the belt, making the operation smoother and solving the problem of frequent belt tensioning and noise problems.

[0013] 2. The connection method between the bucket and the belt has been improved. The bucket and the belt are separated by a non-metallic spacer. In this way, each time the bucket passes through the active roller and the driven roller, the lip of the bucket will not contact the belt surface due to the gap between the partitions, which effectively protects the belt and greatly extends the service life of the belt. Due to the effect of the spacer, the diameter of the active and driven rollers can be reduced during manufacturing, making the elevator more compact and small.

[0014] 3. The welding method of the hoist box has been improved, and sealing gaskets have been designed at all the mounting parts on the box to ensure the sealing of the box. The belt vertical hoist manufactured in a sealed manner can meet most material transportation requirements. BRIEF DESCRIPTION OF THE DRAWINGS
