Device for disassembling and assembling rear axle of mining automobile
Technical Field
The utility model relates to the field of disassembly and assembly of rear axles of automobiles, in particular to a device for disassembling and assembling a rear axle of a mining automobile.
Background
When the rear axle of the D32 mining dump truck/automobile is disassembled, a carriage is required to be lifted by a crown block, and a forklift extension arm is used for supporting a rear axle bumper after a connecting bolt is disassembled and is connected by a steel wire rope. The workman uses the crow bar to pry the tire in both sides, and fork truck cooperation pulls the rear axle and removes. The forklift must move synchronously with the rear axle and maintain a consistent speed of left and right movement throughout the process. When the rear axle is installed, a forklift is required to support the rear axle, meanwhile, a worker moves wheels forwards, and the forklift adjusts the position of the rear axle left and right up and down so as to align the rear axle seat holes.
The existing mining truck rear axle dismounting mode has certain defects. Firstly, the forklift is matched with a worker to move the rear axle back and forth in the whole maintenance process, if the front and back movement speed of the forklift is inconsistent with the speed of prying tires, the forklift and the rear axle can be connected and fall off, and the rear axle is turned over to be dangerous. Secondly, when aligning the seat hole, if the fork truck moves about and adjusts inaccurately, the seat hole can't align, then need multiple trial and error, has prolonged the maintenance time. Finally, more than 6 operators are needed in the overhaul process, so that the risk factors are increased.
