Detailed Description

The following detailed description of the embodiments of the present invention will be provided with reference to the accompanying drawings, but the present invention is not limited to these embodiments, and any modifications or substitutions in the basic spirit of the embodiments will still fall within the scope of the present invention as claimed in the appended claims.

Example 1: as shown in fig. 1, 2, 3 or 4, a TBM trailer comprises a trailer frame 2 with a trailer frame base 1, wherein a traveling mechanism 3 is arranged on the lower end face of the trailer frame base 1; a direction adjusting mechanism 4 is arranged on the lower end face of the trailer frame base 1 and on one side of the traveling mechanism 3, and the direction adjusting mechanism 4 is connected with the traveling mechanism 3; an arc-surface travelling wheel 5 is arranged on the lower end face of the trailer frame base 1 and in front of the direction adjusting mechanism 4.

Further, the direction adjusting mechanism 4 comprises a horizontally arranged direction adjusting oil cylinder 6, the telescopic end of the direction adjusting oil cylinder 6 is hinged with an oil cylinder bracket 7 arranged on the lower end face of the trailer frame base 1, and the other end of the direction adjusting oil cylinder 6 is connected with the traveling mechanism 3.

Further, the traveling mechanism 3 comprises a wheel box 8, a direction-adjusting wheel axle 9 is arranged in the wheel box 8, and a direction-adjusting wheel 10 is arranged on the direction-adjusting wheel axle 9; a horizontal traveling wheel 11 is arranged in the wheel box 8 and behind the direction-adjusting wheel 10, a pair of turning supporting shafts 12 are arranged above the wheel box 8, and the upper parts of the turning supporting shafts 12 are connected with the lower end surface of the trailer frame base 1 through shaft connecting plates 13; the turning supporting shaft 12 is matched with the wheel box 8 through a shaft hole.

Further, a direction adjusting oil cylinder wheel box connecting seat 14 is arranged on the outer wall of the tail portion of the wheel box 8, and the direction adjusting oil cylinder 6 is connected with the direction adjusting oil cylinder wheel box connecting seat 14 in a hinged mode.
