In some embodiments, as shown in fig. 1, the cutting machine 1 further includes a traction device 60, and the traction device 60 is fixedly connected to the frame 10 and is configured to drive the cutting machine 1 to move in the first direction, it can be understood that the traction device 60 enables the cutting machine 1 to automatically move along the length direction of the track plate, so that the cutting machine 1 can automatically move along the length direction of the track plate while cutting the mortar layer between the track plate and the base without manually pushing the cutting machine 1, and thus the cutting machine 1 can automatically complete cutting of the mortar layer under the track plate of the desired road section. It should be noted that the traction device 60 may be any structure capable of driving the cutting machine 1 to move along the first direction, for example, the cutting machine 1 further includes a wheel located below the frame 10, and the traction device 60 is a wheel-side motor connected to the wheel, and the wheel-side motor drives the wheel to rotate so as to enable the cutting machine 1 to move along the extending direction of the track plate; illustratively, as shown in fig. 6, the traction device 60 includes a second driving element 61 and a traction rope 62, the second driving element 61 is fixedly connected with the frame 10, one end of the traction rope 62 is connected with a fixed structure in the external environment, and the traction rope 62, under the driving applied by the second driving element 61, enables the traction rope 62 to apply a force to the fixed structure and transmit a reaction force applied by the fixed structure to the frame 10, so as to drive the cutting machine 1 to move along the length direction of the track slab, wherein the fixed structure in the external environment may be a fixed cross bar fixedly connected with the ground in the external environment.

It should be noted that, according to the structure of the second driving element 61, the connection manner of the pulling rope 62 and the second driving element 61 is different, for example, the second driving element 61 is a linear motor, one end of the pulling rope 62 is connected to the linear motor, and the other end of the pulling rope 62 is fixedly connected to the fixed cross bar, so that the cutting machine 1 is driven to move along the extending direction of the track slab by the linear pulling force output by the linear motor; illustratively, the second driving member 61 is a rotating motor, as shown in fig. 6, the cutting machine 1 further includes a transmission chain 63 and a sprocket 64, the sprocket 64 is fixed to an output shaft of the rotating motor, one end of the transmission chain 63 is connected to the frame 10, the transmission chain 63 is connected to one end of the pulling rope 62 after bypassing the sprocket 64, the other end of the pulling rope 62 is fixedly connected to the fixed cross bar, the sprocket 64 and the transmission chain 63 convert the rotating motion output by the rotating motor into a linear motion, the pulling rope 62 transmits the force applied by the fixed cross bar to the pulling rope 62 to the transmission chain 63 and to the sprocket 64 through the transmission chain 63, so that the cutting machine 1 is driven to move along the extending direction of the track slab by applying a driving force to the sprocket 64 to the frame 10. Compared with a driving scheme that the wheels are driven to rotate and the cutting machine 1 is driven by the friction force between the wheels and the road surface, the requirement for the adhesion force which can be provided by the traction rope 62 for driving the cutting machine 1 to move in a pulling force mode on the road surface is low, the cutting machine 1 can be applied to different road surface environments while larger driving force is applied to the cutting machine 1, and the universality of the cutting machine 1 is further improved.
