[0002] Usually, in construction machinery products, there is a counterweight component used to balance the center of gravity of the whole machine, and the counterweight is connected to the platform by bolts. Under normal circumstances, the counterweight of the excavator is close to important parts such as the engine and hydraulic pump. Since the entire counterweight is fixed to the excavator platform and cannot be moved, when these important parts need to be replaced, repaired and maintained, the counterweight must be removed by lifting tools before replacement, repair and maintenance can be carried out.

[0003] However, mining excavators are large in size and use heavy counterweights that cannot be disassembled at all. When maintenance personnel perform maintenance on the mining excavator engine, they can only stand on the top of the engine compartment, squatting or leaning down, which is extremely inconvenient and the maintenance time is too long, seriously affecting the progress of the project.

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] A typical implementation of the present utility model is as follows Figure 1As shown, a maintenance passage for a mining excavator includes an engine compartment 1 and a counterweight 2. The counterweight 2 is located behind the engine compartment 1. An engine maintenance passage 3 is provided between the engine compartment 1 and the counterweight 2. The engine maintenance passage 3 is connected to the engine compartment 1. By providing the engine maintenance passage 3 between the engine compartment 1 and the counterweight 2, a worker can reach the rear of the engine compartment 1 to perform maintenance on the engine, thereby improving the convenience of engine maintenance.

[0024] A right side channel 4 is arranged on the right side of the excavator, one end of the engine maintenance channel 3 is connected to the right side channel 4, and a first boarding gate 5 is arranged at the end of the right side channel 4 away from the engine maintenance channel 3. A climbing device, such as a ladder, escalator, etc., is arranged at the first boarding gate 5. When the engine needs to be repaired and maintained, the right side channel 4 can be entered from the first boarding gate 5, and the engine maintenance channel 3 can be entered through the right side channel 4.

[0025] like Figure 2 As shown, a first channel door 6 is further provided between the engine maintenance channel 3 and the right channel 4. The height of the first channel door 6 is the same as that of the engine maintenance channel 3. Under normal circumstances, the first channel door 6 is in a closed state. The engine maintenance channel 3 is closed by the first channel door 6, and non-staff are prohibited from entering the engine maintenance channel 3, thereby avoiding safety accidents.

[0026] A left side passage 7 is provided on the left side of the excavator. The left side passage 7 is located on one side of the cab 8 and is connected to the cab 8. A second boarding gate 9 is provided in the middle of the left side passage 7. A climbing device, such as a ladder, escalator, etc., is provided at the second boarding gate 9. Workers can enter the left side passage 7 from the second boarding gate 9 and enter the excavator cab 8 from the left side passage 7.
