Technical Field
[0001] The utility model relates to the technical field of oil cylinder cover plates, in particular to an oil cylinder cover plate for a dumper leaning plate which is convenient for maintenance. Background Art
[0002] A car tipper is a large piece of machinery used to dump open-top train cars. It typically consists of a drive, end rings, three main beams, a car hold-down mechanism, and a car support plate. The tipper unloads the material loaded inside the open-top train car by tipping it over. Before the tipper flips, the car support plate, pushed by a hydraulic cylinder, extends and presses against the side of the car. The hydraulic cylinder then pushes the car hold-down mechanism downward, pressing the side of the car. To prevent material from striking the car support plate cylinder during tipping, a cover is installed above the cylinder.
[0003] The traditional oil cylinder cover plate is composed of angle steel and steel plate. Although the structure is simple and strong, it is inconvenient to disassemble and assemble. When the oil cylinder needs to be inspected or repaired, the space between the cover plate and the oil cylinder is relatively narrow and there is not enough operating space. At this time, it is necessary to loosen the fastening bolts between the cover plate and the back of the vehicle support plate, and then use the maintenance crane to lift the cover plate to the ground. After the inspection or repair is completed, the maintenance crane is used to lift the cover plate to its original position, and finally tighten the fastening bolts between the cover plate and the back of the vehicle support plate. Not only is the process cumbersome and time-consuming, but it also carries a high risk during disassembly and assembly. Utility Model Content
