Description

Lifting device

Technical Field

The invention relates to the technical field of grinding machine accessories, in particular to a lifter.

Background

In various crushing and grinding process flows of a dressing plant, ore is discharged after the ore is ground by the ore semi-autogenous grinding machine, and the ore pulp reaching the qualified granularity is discharged from the grinding machine, so that the processing capacity of the whole crushing and grinding process flow is improved, and the production capacity of the dressing plant is improved.

However, most of the lifters used in the existing equipment adopt a common steel skeleton structure, and are easy to wear. Therefore, on one hand, the service life of the lifter is relatively short, and the productivity is limited; on the other hand, the service life of the lifter is inconsistent with that of the lifters at other parts in the mill, and the lifter cannot be synchronously overhauled and replaced.

Disclosure of Invention

The invention aims to provide a lifter which has the characteristics of long service life and easiness in maintenance.

The technical scheme adopted by the invention is as follows: the lifter comprises a fan-shaped body, wherein a rubber material layer is arranged on the surface of the body, a framework with a square cross section is fixed on the upper surface of the body, and the framework is made of cast wear-resistant metal.

The framework is fixed on the body through bolts.

And a supporting block is arranged between the lower side surface of the framework and the upper surface of the body.

The front side and the rear side of the framework are in the shape of casting polyhedral bodies which are symmetrical with each other.

Compared with the prior art, the invention has the advantages that: long service life and easy maintenance. The body of the lifter is provided with the framework formed by casting the wear-resistant metal blocks, so that the rigidity of the lifter is increased; and all set up the rubber layer on the surface of body and skeleton, after rubber wearing and tearing, skeleton and body square parameter are worn and torn, have greatly improved the whole life of lifting mechanism.

Drawings

The invention is further illustrated with reference to the following figures and examples:

fig. 1 is a schematic perspective view of an embodiment of the present invention.

In the figure:

10. a body; 20. a framework; 30. a bolt; 40. and (7) a supporting block.

Detailed Description

Examples, see FIG. 1: a lifter including a fan-shaped body 10; a plurality of bodies 10 of the same type may constitute a disc type.

Further speaking:

a plurality of frames 20 having a square cross section are fixed on the upper surface of the body 10. The ribs 20 are generally uniformly distributed on the body 10, and the longitudinal direction of the ribs 20 is generally passing through the center of the body 10. The square cross section means that the cross section of the frame 20 cut by any one of the planes perpendicular to the longitudinal direction of the frame 20 is entirely square, and is allowed to have a rounded corner and to have a local minute projection or recess. The skeleton 20 is made of cast wear-resistant metal, such as Cr26. And a rubber material layer (not shown) is provided on the surface of each of the body 10 and the bobbin 20.

And (3) optimizing:

the frame 20 is fixed to the body 10 by bolts 30 for easy assembly, disassembly and maintenance.

Support blocks 40 are provided between the lower side of the frame 20 and the upper surface of the body 10, and the support blocks 40 are preferably integrally formed with the frame 20 by integral casting or the like.

The front and rear sides of the frame 20 are cast polyhedral shapes which are symmetrical to each other so that the lifting frame can rotate bidirectionally, and when one side of the frame 20 is seriously worn, the frame 20 can be continuously used after the direction is changed.

Like this, the skeleton of setting has increased the rigidity of lifting mechanism, and the rubber layer that all sets up on the surface of body and skeleton is preferred to participate in wearing and tearing, and later skeleton and body side participate in wearing and tearing, have greatly improved the whole life of lifting mechanism.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
