According to the rear support assembly of the heading machine provided by the embodiment of the invention, the rear support arm mechanism 2 and the auxiliary travelling mechanism 3 are arranged on the rear body frame 1 of the heading machine. The rear support arm mechanism 2 can be extended or retracted to the rear body frame 1, and can provide a supporting force for the rear body frame 1 when the rear support assembly of the heading machine is extended. The auxiliary walking mechanism 3 comprises a driving assembly 32, a second telescoping mechanism 34 and a walking wheel 36, wherein the driving assembly 32 is connected with the walking wheel 36 and can drive the walking wheel 36 to rotate so as to provide forward power for the equipment. Meanwhile, the driving assembly 32 is provided with a guide wheel 324, and the rear support arm mechanism 2 is provided with a guide rail 222, when being installed, the guide wheel 324 is slidably installed on the guide rail 222, so that the guide rail 222 can control the traveling direction of the guide wheel 324, and further control the direction of the driving assembly 32. The second telescopic mechanism 34 is connected between the drive assembly 32 and the rear body frame 1 and is hinged to the drive assembly 32 and the rear body frame 1, and in use, the second telescopic mechanism 34 can control the drive assembly 32 to enter the working position so that the drive assembly 32 can provide power for the heading machine, and when no work is required, the second telescopic mechanism 34 is contracted to pull the drive assembly 32 back to the starting position (as shown in fig. 12), and the guide wheels 324 can control the movement direction of the drive assembly 32 when the second telescopic mechanism 34 is extended or contracted so that the drive assembly 32 can move along the guide rails 222.
In the actual use process, as shown in fig. 1 and 2, the rear support assembly of the heading machine includes two working modes, namely a support mode and an auxiliary walking mode, in the support mode, the rear support arm mechanism 2 extends out to provide a support force for the heading machine, the second telescopic mechanism 34 extends out correspondingly according to the working state of the support mode, so that the driving assembly 32 is kept at a corresponding initial position, at this time, the second abutting structure on the upper portion of the driving assembly 32 is in a non-abutting state with the first abutting structure of the rear support arm mechanism 2, and at this time, only the guide wheel 324 on the driving assembly 32 is connected with the guide rail 222 on the rear support arm mechanism 2. In the auxiliary walking mode, after the rear supporting arm mechanism 2 extends out, the second telescoping mechanism 34 extends out further on the original basis, so that the driving assembly 32 can reach the working position along the guide rail 222, at this time, the driving assembly 32 provides power for the walking wheels 36, and further provides forward power for the heading machine, at this time, the second abutting structure on the upper portion of the driving assembly 32 is in an abutting state with the first abutting structure of the rear supporting arm mechanism 2, at this time, except that the guide wheel 324 on the driving assembly 32 is connected with the guide rail 222 on the rear supporting arm mechanism 2, the second abutting structure on the upper portion of the driving assembly 32 is also abutted against the first abutting structure arranged on the rear supporting arm mechanism 2, namely, the rear supporting arm 22 can receive acting force acting on the driving assembly 32. When the driving assembly 32 is not needed to work, the driving assembly 32 is firstly retracted to the initial position, and then the rear support arm mechanism 2 is retracted. Meanwhile, the drive assembly 32 and the rear support arm mechanism 2 are separated from each other. In the walking assist mode, the drive assembly 32 abuts against the rear support arm mechanism 2. The acting force borne by the auxiliary travelling mechanism 3 can reach the rear supporting arm mechanism 2, so that the auxiliary travelling mechanism 3 does not need to bear the pressure generated by the whole heading machine due to gravity and the like, but transmits the pressure to the rear supporting arm 22, and the pressure borne by the auxiliary travelling mechanism 3 is transmitted to the rear supporting arm 22. When the auxiliary traveling mechanism 3 is arranged, the strength requirement of the auxiliary traveling mechanism 3 is reduced, so that the structure of the auxiliary traveling mechanism 3 can be simplified, and the overall cost of the product is reduced. Compared with the prior art, the self weight of the equipment is reduced, and meanwhile the auxiliary walking mechanism 3 can bear larger circumferential force. Meanwhile, the device is more flexible, and can continuously provide auxiliary power for the heading machine aiming at various terrains. Thereby solving the problem that the development machine is trapped due to insufficient power storage.
Further, as shown in fig. 2 and 3, the rear support arm mechanism 2 includes: a rear support arm 22, a first end of the rear support arm 22 being rotatably connected to the rear body frame 1, the rear support arm 22 being provided with a guide rail 222; first telescopic machanism 24, the one end and the back body frame 1 of first telescopic machanism 24 can be connected with rotating, and the other end of first telescopic machanism 24 can be connected with rotating with the second end of back supporting arm 22, and wherein, when first telescopic machanism 24 is flexible, can drive back supporting arm 22 and rotate to realize stretching out or retracting of back supporting arm 22.

When the first telescopic mechanism 24 extends out, the rear supporting arm 22 can be driven to rotate, so that the rear supporting arm 22 extends out and the rear supporting arm 22 can be attached to the ground. In this arrangement, the rear support arm mechanism 2 is in the form of a telescopic structure, which is common, and therefore can reduce costs. Of course, the rear support arm mechanism 2 may be other forms of support structures. When the first telescopic mechanism 24 extends and retracts to drive the rear supporting arm 22 to swing up and down by taking a direct hinge point with the rear body frame 1 as a center, the auxiliary walking mechanism 3 adjusts the initial position posture of the auxiliary walking mechanism in a small range through a lap joint mode that the guide wheel 324 is tangent to the guide plate 322, and the movement of the rear supporting arm 22 is not interfered.
Further, for better practicability of the auxiliary traveling mechanism 3, the implementation height of the auxiliary traveling mechanism 3 can be divided into 5 working gears and an initial position by a control technician.
