Description

Technical Field

[0001] The invention relates to the technical field of mining dump trucks, and in particular to a platform, a device and a method for conveniently disassembling and assembling a fender of a mining dump truck. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] A mining dump truck is a heavy-duty dump truck used in open-pit mines to complete rock and earth stripping and ore transportation tasks. Its working characteristics are short transportation distance and heavy load. Mining dump trucks have a large load mass and a particularly tall appearance. The height of some mining dump trucks is usually more than 7.5 meters, and the height of the corresponding mining dump truck tires is also relatively high, and the diameter of some tires is more than 4 meters.

[0004] Mining dump trucks operate in harsh environments in mining areas. Their fenders are frequently impacted by mud, sand and stones and are easily damaged. They need to be disassembled and repaired regularly. Figure 1 As shown, the fender 15 includes two parts. The upper side of the fender is a rigid section 15-1, which is connected to the vehicle body and connected to the rubber section 15-2. The inventor found that the disassembly and assembly of the fender has the following problems:

[0005] The rigid section of the fender is tilted to the vertical surface, and the space around the fender is narrow, especially the gap between the tire and the fender is small, so it is difficult to place and use an ordinary ladder, which makes the disassembly and assembly work difficult, and there are problems such as low efficiency of fender replacement and long maintenance time;

[0006] Due to the tall body and large tires, the height of the fender on the body is also high, and the mass of the fender is also large. The bottom of the rubber section is in the middle of the wheel. During the disassembly and assembly process, the fender falls directly to the ground. If the ladder is located under the fender, the safety risk is high. That is, the existing disassembly and assembly method increases the operating risk of maintenance personnel and is prone to cause safety accidents. Summary of the invention
