Description

Technical Field

[0001] This invention relates to the field of coal mine drilling rig technology, and in particular to a tracked transport device for mining. Background Technology

[0002] In modern large-scale coal mines, various support equipment is typically required at the work site, such as shield supports and back supports. Furthermore, a variety of working equipment is needed on the coal mine's integrated working face, including coal mining machines, continuous miners, excavators, drilling rigs, cables, pipelines, and so on. In a relatively large mining face, the number of supports can reach hundreds, and the number of other working equipment is also considerable. This equipment needs to be moved and transported using transport vehicles. These supports and working equipment are large in size and heavy in weight. Current methods for moving supports and equipment generally use "rail-mounted flatbed cars with winches" or monorail cranes to move supports. While these two methods achieve the desired movement, they also have disadvantages such as poor safety, high production costs, low work efficiency, and high labor intensity for workers. They are also not flexible enough and have low transport efficiency when working underground.

[0003] Due to the narrow space and harsh operating environment of underground roadways, transport vehicles must be small in size, stable in transport, and highly maneuverable to complete equipment moving tasks. Therefore, there is an urgent need for a flexible and efficient tracked transport device for mining to achieve mechanized operations for moving and relocating unit supports. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a tracked transport device for mining, which enables rapid transport and relocation of tunnel unit supports.
