An unloading height adjustment device for a trackless transport vehicle used in coal mines

Abstract

The invention discloses a device for adjusting the unloading height of cargo compartments of trackless transport vehicles used in coal mines, which is suitable for limiting and adjusting the unloading height of cargo compartments of trackless transport vehicles in coal mines. The device completes the data collection by the distance sensor, determines whether to limit and the height of the limit, completes the action of the limit pin through the memory alloy, and completes the limit of the cargo compartment through the mechanical limit device. The mechanical limit device is driven by magnetically controlled memory alloy, and at the same time, the reliability of the limit pin is increased by using the dead point principle of the four-bar linkage mechanism. The cargo box can better adapt to different working conditions. After adding the height adjustment device, the cargo box of the transport vehicle can better adapt to different unloading heights, which improves the adaptability of the trackless rubber-tyred transport vehicle in coal mines.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a device for adjusting the unloading height of a cargo compartment of a trackless transport vehicle used in coal mines. Background technique [0002] Explosion-proof trackless rubber tire dump truck plays a very important role in coal mine auxiliary transportation. In recent years, with the mining of thin coal seam and ultra-thin coal seam coal mines, higher requirements have been put forward for the adaptability of explosion-proof dump trucks. If the dump truck with a single unloading height only adapts to the height of the coal mine roadway, manual assistance is often required to complete the complete unloading due to the limited lifting angle of the cargo box during the unloading process, which seriously affects the unloading efficiency of the dump truck on the coal mine ground. If the self-unloading height is high, it is easy to have a top-touching accident when perfo...

Problems solved by technology

If the single unloading height dump truck only adapts to the height of the coal mine roadway, manual assistance is often required to complete the complete unloading due to the limited lifting angle of the cargo box during the unloading process, which seriously affects the unloading efficiency of the dump truck on the coal mine ground

If the self-unloading height is high, it is easy to have a top-touching accident during underground self-unloading operations, which seriously affects production safety
