Referring to fig. 1 to 5, fig. 1 is a schematic structural diagram of a traveling mechanism according to an embodiment of the present invention; FIG. 2 is a front view of FIG. 1; FIG. 3 is a cross-sectional view of FIG. 1; FIG. 4 is a top view of FIG. 1; fig. 5 is a top view of the swivel base of fig. 1 when it is rotated.
The utility model provides a traveling mechanism, which comprises a connecting seat 1, a rotating seat 2, a limiting part 3 and a wheel box body 4, wherein the connecting seat 1 is used for being connected with a trailer matched with the rear part of a heading machine, and the rotating seat 2 is rotatably connected with the connecting seat 1, so that the rotating seat 2 can horizontally rotate relative to the connecting seat 1, namely, the direction of a rotating shaft 9 line of the rotating seat 2 is a vertical direction; the rotating base 2 is provided with a limiting hole 21, the limiting piece 3 is connected with the connecting base 1, the limiting piece 3 penetrates through the limiting hole 21, and a preset moving amount is arranged between the limiting piece 3 and the limiting hole 21 so that the limiting hole 21 can slide relative to the limiting piece 3 when the rotating base 2 rotates relative to the connecting base 1; the wheel box body 4 is connected with the rotating seat 2, and the wheel box body 4 is provided with a traveling wheel 5.
It can be understood that the size of the preset movement between the limiting member 3 and the limiting hole 21 determines the range of relative movement between the limiting member 3 and the limiting hole 21, that is, when the inner sidewall of one end of the limiting hole 21 contacts the limiting member 3, the rotating base 2 is prevented from continuing to rotate under the stopping action of the limiting member 3, so that the two ends of the limiting hole 21 define the rotating range of the rotating base 2.
When the travelling mechanism is applied to a rear matched trailer of a heading machine, the connecting seat 1 of the travelling mechanism is connected with the rear matched trailer of the heading machine, so that the travelling mechanism drives the rear matched trailer of the heading machine to advance, in the advancing process, when the travelling mechanism needs to turn, the travelling wheels 5 drive the wheel box body 4 to turn, and then the wheel box body 4 drives the rotating seat 2 to rotate horizontally relative to the connecting seat 1, so that the travelling wheels 5 can form a certain included angle relative to the rear matched trailer of the heading machine, and the turning is realized. Moreover, under the matching limit of the limiting piece 3 and the limiting hole 21, the maximum steering angle of the walking wheel 5 can be limited, namely, the walking wheel 5 can not exceed the maximum steering angle when steering along the surrounding terrain or external force, thereby preventing the accident of large steering and side turning caused by the uneven walking track of the walking wheel 5.
Therefore, the travelling mechanism can meet the tunnel construction requirement of a small turning radius of a trailer matched behind a heading machine, has safety, and is not easy to cause side turning accidents caused by an overlarge steering angle.

As shown in fig. 5, when the traveling mechanism needs to turn, the position of the limiting adjusting piece 7 on the steering adjusting piece 6 is adjusted, so that the steering adjusting piece 6 has a certain sliding movement amount relative to the connecting wall 22, that is, the steering limitation can be removed, so that the traveling mechanism can realize turning, and specifically, the position of the limiting adjusting piece 7 on the steering adjusting piece 6 can be determined according to the actually required maximum turning angle α of the traveling mechanism; when the running gear needs to adapt to terrain and stably run, the position of the limit adjusting piece 7 on the steering adjusting piece 6 is adjusted, so that the steering adjusting piece 6 has smaller sliding movement relative to the connecting wall 22, and the rotating seat 2 has a small steering angle.
