CN103552811A - Upper guide rail structure of conveyor - Google Patents

Abstract

The invention provides an upper guide rail structure of a conveyor. By the aid of the upper guide rail structure, petroleum coke is avoided from being attached to an upper guide rail after being crashed and screened, the service life of the upper guide rail is prolonged, and normal operation of equipment is guaranteed. The upper guide rail structure comprises a support and is characterized in that mounting and fixing plates are welded on two inner sides of the upper portion of the support, and upward U-shaped notches are uniformly distributed at corresponding positions of the mounting and fixing plates on two sides. Each carrier roller comprises a central shaft, bearings at two ends, and a shell, wherein the shell is sleeved outside the central shaft through the bearings at two ends, two ends of the central shaft are exposed outside the shell, two ends of the central shaft respectively support in the corresponding U-shaped notches on two sides, and the carrier rollers are uniformly arranged on the upper plane of the support.

Description

A kind of upper rail structure of conveyer

Technical field

The present invention relates to the technical field of environment engineering physical construction, be specially a kind of upper rail structure of conveyer.

Background technology

In the petroleum coke transport process of carbon element industry material before calcined storehouse, need to carry the petroleum coke after crushing and screening by conveyer, the upper rail of existing conveyer is the straight line steel plate of an evagination, straight line steel plate is paved on uniform support tube, and the petroleum coke material after crushing and screening enters after conveyer, and material easily sticks between die forging chain and upper rail, because of chiseling property of material mill extremely strong, cause upper rail serious wear, service life is extremely short and maintenance is frequent, and the equipment that has a strong impact on normally moves.

Summary of the invention

For the problems referred to above, the invention provides a kind of upper rail structure of conveyer, it can not stick on upper rail the petroleum coke after crushing and screening, makes the life-span of upper rail long, guarantees the normal operation of equipment.

A kind of upper rail structure of conveyer, its technical scheme is such: it comprises support, it is characterized in that: two inner sides, top of described support are welded with mounting plate, the correspondence position of the described mounting plate of both sides is evenly equipped with towards upper U-shaped notch, carrying roller comprises center shaft, the bearing at two ends, shell, described outer cover suit is in the outside of described center shaft, the two ends of described center shaft expose to described shell, described shell is loaded on the outside of described center shaft by the described bearing carrier ring at two ends, the two ends of described center shaft are supported on respectively in the U-shaped notch of correspondence of both sides, described carrying roller is distributed in the upper plane of described support.

Adopt after the present invention, carrying roller is distributed in the upper plane of described support, the two ends of the center shaft of carrying roller are supported on respectively in the U-shaped notch of correspondence of both sides, it makes chain operation scheme become rolling bearing formula from sliding bearing formula, stop guide rail sizing, it can not stick on upper rail the petroleum coke after crushing and screening, makes the life-span of upper rail long, guarantees the normal operation of equipment.
