Description

Technical Field

[0001] This utility model relates to the field of coal mining machinery, specifically to a multi-functional coal mining vehicle with a power supply trailer. Background Technology

[0002] Existing mining vehicles primarily use diesel engines as their power source. The diesel engine drives the hydraulic pump in the hydraulic station, which in turn drives the hydraulic motor to rotate, enabling operation on underground mine roads. While offering advantages such as high operating power, these vehicles pose pollution problems in coal mines. Furthermore, multi-functional vehicles require long driving ranges, and existing battery-powered new energy vehicles are not suitable for the underground working environment due to limitations in battery installation location and battery replacement efficiency. Therefore, there is an urgent need to design a power source-driven main unit that can be adapted to various operating machinery in mines while also facilitating the replacement, disassembly, and relocation of lithium battery power supplies.

[0003] Utility model patent CN 223131796 U discloses a mining lithium battery transport vehicle, including a vehicle body, lithium battery packs, and a crane arm. The upper surface of the vehicle body has a battery compartment for storing the lithium battery packs, with the compartment opening upwards. The crane arm is mounted on the vehicle body, and the battery compartment is within the crane arm's lifting range. The crane arm in this mining lithium battery transport vehicle not only enables automatic loading and unloading of materials but also, in conjunction with the upward-facing opening of the battery compartment, allows for the removal and installation of new lithium battery packs, significantly improving battery swapping efficiency and saving replacement time, thus enhancing the vehicle's operational efficiency. However, the disclosed structure of this mining lithium battery transport vehicle requires individual disassembly, assembly, and transportation using a truck-mounted crane, which reduces work efficiency. Furthermore, this transport vehicle only serves a transportation function and does not have the capability to adapt to various underground mining machinery. Utility Model Content
