Description

Technical Field

[0001] The utility model relates to the technical field of control boxes, and particularly relates to a rear control box for an underground loader. Background Art

[0002] Underground loaders are widely used in coal mines, metal mines, non-metal mines and tunnel projects, and are mainly used for the loading, unloading and transportation of ores, coal and soil. Among them, for underground loaders with a model size of 2.5m 3 and below, due to the volume of the cab being compressed by other functional components, the space in the cab will be too small. A relatively common improvement method is to place the auxiliary driving function control components on the rear frame through a rear control box.

[0003] In the prior art, the driver is in the driving position and needs to be able to operate the rear control box conveniently. Therefore, the installation height of the rear control box needs to be within the operation range of the driver. The height of the rear control box is limited, which in turn leads to a relatively small volume of the rear control box, making it difficult to accommodate various electrical components required, such as relays, circuit breakers, 24V power supplies, etc. Obviously, the disadvantage is that due to the relatively small volume of the rear control box, the arrangement interval of various electrical components is also relatively small, making the later maintenance work relatively difficult.
