Repair process for labyrinth dustproof structure of conical main engine

Abstract

The invention relates to the technical field of conical crushing equipment, in particular to a repair process for a labyrinth dustproof structure of a conical main engine. The repair process is characterized by comprising the following steps: disassembling corresponding parts, cleaning accumulated dust and oil stains, checking the abrasion condition of the labyrinth dustproof structure, polishing abrasion parts, preparing plates, conducting spot welding fixing on the plates, forming a plate ring, detecting the height of the upper end of the plate ring, evenly welding the whole plate ring, and cleaning and polishing weld joints and welding slag; pre-assembling, checking the matching condition, and assembling corresponding parts. The repair process provided by the invention is simple and convenient to operate, can complete repairing without a large amount of work on a construction site; and the effect after repairing is basically the same as that of an original labyrinth dustproof structure, so that the later maintenance cost is effectively reduced, the labor intensity of operators is reduced, the downtime of equipment is greatly shortened, the work efficiency is improved, and the influence of equipment shutdown on customers is reduced.

Description

technical field [0001] The invention relates to the technical field of cone crushing equipment, in particular to a repair process for a labyrinth dustproof structure of a cone main engine. Background technique [0002] During the working process of the cone crusher, the crushed material falls from the bottom of the cone crusher in the state of free fall, and then is transported to other places through the conveying device. In the inner cavity of the cone crusher, there are four internal cantilever beams It always supports the inner cavity of the cone crusher, so that the cone crusher is stable, reliable and can run continuously. [0003] However, it is precisely because of the existence of the cantilever beam that it will block the falling of the crushed material to a certain extent. With the prolongation of the use time, the material will gradually accumulate on the cantilever. The speed of the accumulated material depends on the water content, mud content, The content of ...

[0003] However, it is precisely because of the existence of the cantilever beam that it will block the falling of the crushed material to a certain extent. With the prolongation of the use time, the material will gradually accumulate on the cantilever. The speed of the accumulated material depends on the water content, mud content, The content of non-broken materials, etc., non-broken materials such as wood chips, rubber, plastics, etc., when the materials accumulate to a certain height, it will slowly wear the labyrinth dustproof structure inside the cone crusher. In addition, when the downstream equipment of the crushing production line, due to some When some faults lead to shutdown, while the cone crusher is still working, the crushed material has no time to be conveyed from the bottom of the cone crusher, and the crushed material will continue to accumulate in the cone crusher, which will also wear the maze of the cone crusher Dust-proof structure, once the above situation occurs, it will cause the labyrinth seal failure of the cone crusher, or cause a large amount of sand to enter the inside of the cone crusher, causing serious damage to the equipment and greatly increasing the maintenance cost in the later period
