Description

Technical Field

[0001] The utility model relates to the field of design and manufacture of parts of auxiliary transportation equipment in underground coal mines, in particular to an integrated rotary articulated steering mechanism for a support transport vehicle and the support transport vehicle. Background Art

[0002] A large number of support brackets are used underground in coal mines. As the mining progress continues, the support brackets are often moved, transported and installed by support transporters. The existing universal articulated devices of existing support transporters use welding at key connection parts, which are subject to large forces and may crack after long-term use. There are no constraints on the upper and lower joints of the front and rear frames. The uneven ground causes up and down movement during walking. Long-term use will cause the connecting plate of the articulated part to wear and deform, resulting in large steering resistance, which will seriously affect the use of the vehicle. The articulated shaft relies on spline connection to ensure accuracy. Long-term use will cause severe wear and tear, and the matching clearance will increase, which will seriously affect the use of the vehicle.

[0003] Therefore, it is necessary to improve one or more problems existing in the above-mentioned related technical solutions.
