Description

Technical Field

[0001] The utility model relates to a chassis tool box, a chassis assembly and a mining excavator, belonging to the technical field of excavators. Background Art

[0002] Mining excavators are generally crawler-type walking systems, and the crawler connection form is mainly a kingpin transition fit or an interference fit. When disassembling and repairing, it is necessary to use tools such as a press or a sledgehammer. When repairing and maintaining other parts, various disassembly and repair tools and accessories such as bolts and washers are also required, which requires the excavator to be equipped with a corresponding tool box. The tool box of a mining excavator is generally designed on the vehicle. Because the chassis of a mining excavator is high off the ground, maintenance personnel need to climb up the turntable through an escalator and then take out the tools from the tool box, which is extremely inconvenient. In addition, the tool box has limited space and can only store smaller tools, which is less practical.

[0003] The existing technical solutions currently available:

[0004] An excavator chassis toolbox and excavator (CN209293092U), this patent discloses an excavator chassis toolbox, which is located between the top plate and the bottom plate of the chassis X-frame, and is a semi-enclosed structure. After the toolbox is fixed, it forms a toolbox cavity structure together with the X-frame upright plate, top plate and bottom plate. Because there are multiple gaps between the toolbox and the X-frame, small accessories are easy to fall out of the gaps in the toolbox; because there is no baffle inside, if heavier tools are placed, the X-frame is easy to be damaged when the equipment shakes during operation; this patented toolbox places tools by opening the cover at the top, and the top opening method is only suitable for small-tonnage excavators, and is not suitable for mining excavators that are higher off the ground.
