Dismounting tool and method for dismounting axle of sintering trolley

Abstract

The invention discloses a dismounting tool and method for dismounting an axle of a sintering trolley and belongs to the technical field of dismounting tools. The dismounting tool comprises a rack used for bearing the trolley. A positioning device used for limiting the forward movement and backward movement of the trolley, a pressing device used for limiting the left-right movement and up-down movement of the trolley, and a jacking device used for dismounting the axle of the trolley are arranged on the rack. By the adoption of the dismounting method and device, protective dismounting and repairing of the axle of the replaced trolley removed from a line are achieved; the dismounting tool has the advantages of being simple in structure, reasonable and clear in stress, convenient and fast to operate and the like; the spare part cost and the maintenance cost of equipment are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of dismantling tooling, and relates to a dismantling device, in particular to a dismantling tooling and method for dismantling a wheel axle of a sintering table. Background technique [0002] As the main equipment of the belt sintering machine, the trolley not only bears the action of its own weight and the weight of the sintered ore, but also suffers from repeated heat for a long time during the whole working process. Due to the harsh working environment, the part that causes damage to the trolley is generally the wheel part. Usually there are four wheel parts, and they are arranged symmetrically on both sides of the trolley. Each wheel part includes a wheel shaft, bearings and running wheels. No matter which The wear and tear of the components will affect the safe running of the trolley. Therefore, it needs to be replaced frequently to ensure the normal operation of the equipment and smooth production. ...

AI Technical Summary

Problems solved by technology

[0003] However, in the past, when repairing the wheel part of the trolley, the trolley was turned sideways or turned upside down on the platform of the press by a crane, and the trolley was compressed by the press, and the wheel part was destructively removed, or it was baked. Hot demolition; this method, first of all, in the lifting and turning process: first, it is very unsafe, there is great uncertainty in the operation of turning over the equipment of more than 10 tons, and improper operation may cause casualties; second The first is that the professional level of lifting is high, and the lifting personnel who are not skilled enough cannot meet the requirements; the third is that the efficiency is very low, and the damage to the wire rope is also very large; secondly, the waste of spare parts is very serious for destructive demolition, and the Hot dismantling needs to waste a lot of manpower and machinery costs
