Description
Technical Field
The utility model belongs to the technical equipment field of colliery machinery, concretely relates to automatic turning device in middle part groove.
Background
The middle groove is a large-batch part in the scraper conveyor, and accounts for about 70-80% of the whole scraper conveyor in terms of total weight or total length, and the length of the middle groove of the single part is generally 1500mm and 1750 mm. The scraper conveyor mainly comprises a baffle ledge, a shovel board ledge, a middle plate, a sealing bottom plate, a rack rail seat and the like, is a body and a material bearing mechanism of the scraper conveyor, is positioned in the middle of the scraper conveyor and is a main part, and the reliability and the service life of the scraper conveyor are directly influenced by excessive abrasion and breakage of a middle groove. The quality of the centerwell therefore determines the life and production capacity of the coal mining system.
In recent years, old coal mining equipment is used after being maintained in each coal mine in order to save cost. For the middle groove, a mode of replacing a middle plate and a bottom plate which are seriously worn and welding a ledge chain channel and an upper edge is adopted. The key welding process of the middle groove mainly comprises the following steps: the ledge is welded with the middle plate and the ledge is welded with the bottom plate, and accounts for more than 80% of the welding amount. The middle tank needs to be turned over for many times in the welding process. The overhaul of the middle groove needs to be turned over and repair-welded for many times due to different degrees of damage at different positions, and even needs to be turned over laterally and vertically to perform repair-welding, wear-resistant deposition and other work on the side surface of the chain channel due to the abrasion of the side surface of the chain channel.
The turning method of the middle trough in the prior art is manual turning and traveling turning. The middle groove is hung to a workpiece overturning area from a welding station, the driving hook is used for hooking the pushing lug at the ledge of the middle groove, the middle groove is overturned after standing, an external force (thrust) is required to be given to the middle groove in the overturning process, and the tripping is frequently caused due to reasons such as the fact that the driving hook descends too fast in the overturning process, so that serious smashing injury is caused to constructors, and meanwhile the workpiece and the overturning area ground are collided. After overturning, the middle groove needs to be hoisted to the welding station again by using a travelling crane, and the process needs to be repeated during each overturning. The turnover engineering wastes time and energy, and the accident rate is increased. And the number of vehicles per span of the plant is only 1-2, so that the waiting time is increased, and the welding work efficiency is reduced. When the overhaul middle groove is subjected to side-stand repair welding, the middle groove needs to be hung to the anti-falling frame after side-stand, and the middle groove is difficult to adjust to the most appropriate welding angle due to irregular middle groove walls, so that the welding is inconvenient, and the welding quality is also influenced.
