[0028] As shown in Figure 1 and Figure 2 , the cable assembly 2 includes a cable shaft 21 and a cable motor 22, the cable shaft 21 is rotatably arranged on the mounting frame 1, and the cable motor 22 is fixedly arranged on the mounting frame 1. One end of the cable shaft 21 is connected with the output shaft of the cable motor 22. The cable shaft 21 provides an orderly winding and releasing platform for the cable. During the operation of the tunneling machine, the cable needs to be stretched or retracted accordingly as the machine moves. The cooperation between the cable shaft 21 and the cable motor 22 can flexibly release or wind the cable according to the moving direction and distance of the tunneling machine, so that the arrangement of the cable is always neat and orderly, and the phenomenon of disorderly winding of the cable in the working area is avoided.
