Description

Technical Field

[0001] The utility model relates to the field of mine mechanical equipment maintenance, in particular to a mine trackless equipment tire disassembly and assembly auxiliary device. Background Art

[0002] At present, trackless equipment is widely used in mining tunnel excavation in major mines around the world, and the existing trackless equipment walking systems all use tire operations. However, the underground working environment is harsh and the road conditions are poor. The tires of trackless equipment are often damaged during use and need to be replaced in time. However, the tires of trackless equipment in mines are relatively large and heavy, which makes disassembly and assembly difficult. At present, major mining companies basically rely on manual disassembly to dismantle the tires of trackless equipment, or equip some trackless equipment with special tire changers. However, manual tire removal is time-consuming and laborious. Even if many people work at the same time and replace the tires, it takes a long time to change a tire; tire changers directly remove tires on the car without removing the rims, and are generally only suitable for special trackless equipment. Moreover, it takes a long time to change tires on site, and if the rims are damaged, they still need to be removed manually. Both solutions take a long time during use, which seriously affects production efficiency. Moreover, the tires of trackless equipment are of different sizes, and are generally large and bulky. If the clamping effect of the tire removal auxiliary device is not good, it is difficult to remove the tire from the rim. The existing patent number CN95240932.1 discloses a special device for disassembling automobile tire rims, which is composed of a frame, a pressure plate, a pressure cylinder, a support cylinder, a walking trolley and a hydraulic system. An auxiliary oil cylinder is arranged in parallel on both sides of the central oil cylinder. The pressure plate is vertically connected to the central oil cylinder, and the two auxiliary cylinders are vertically connected to the ring hook slide. The ring hook slide is provided with a ring hook slide. The tire disassembly operation is completed by the interaction between the pressure plate and the ring hook slide device under the control of the hydraulic system. The use of this equipment has the following advantages: high working efficiency, strong adaptability, no damage to the tire during the disassembly process, and can be widely used for the disassembly of large automobile tire rims in metallurgy, chemical industry, coal, water conservancy and other operations. However, the device adopts a cylinder hydraulic system for control, and the cylinder needs to be replaced frequently, resulting in an increase in cost. Utility Model Content
