By installing the sliding positioning members 10, the crawler can be positioned so that the crawler can be in the central position of the machine body 1, and the crawler can be positioned and clamped, which is convenient for repairing the crawler.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 3, two threaded columns 11 are rotatably connected to the upper surface of the body 1. The outer surfaces of the two threaded columns 11 are both threadedly connected with sleeves 12. The two connecting plates 2 are both threadedly connected to the sleeves 12 close to them. When the threaded columns 11 rotate, the sleeves 12 can be lifted and lowered, so that the track can be clamped through the sliding rods 6 and the rubber pads 7. The bottom ends of the two threaded columns 11 are both fixedly connected with first belt pulleys 13. The two first belt pulleys 13 are connected by a belt drive. A servo motor 14 is installed on the inner bottom wall of the body 1. The output end of the servo motor 14 is fixedly connected to the right threaded column 11. The servo motor 14 can drive the right threaded column 11 to rotate, so that the two threaded columns 11 can rotate synchronously through the belt drive during rotation. The bottom end of the threaded column 11 on the left is fixedly connected with two second belt pulleys 20. The bottom ends of the two rotating rods 18 are both fixedly connected with third belt pulleys 21.

The installation of the resistance plates 22 can increase the friction with the track and prevent the track from shifting during track processing.

[0036] A rapid fixing device for the crawler of a roadheader in this embodiment can clamp the crawler through the cooperation of the slide bar 6, the rubber pad 7 and the spring 8, so that the crawler can be kept stable, and can clamp crawlers of different sizes through the cooperation of the threaded barrel 3 and the threaded rod 4. By installing the sliding positioning member 10, the crawler can be positioned so that the crawler can be at the central position of the machine body 1, and the crawler can be positioned and clamped, which is convenient for repairing the crawler.

[0037] The working principle of the above embodiment is as follows: When positioning and clamping the crawler, the servo motor 14 is started and drives the threaded column 11 on the right side to rotate. When the threaded column 11 on the right side rotates, it can drive the threaded column 11 on the left side to rotate through the transmission of the belt. During the rotation of the threaded column 11 on the left side, it can drive the two rotating rods 18 to rotate through the belt. During the rotation of the two rotating rods 18, the sliding positioning member 10 can be mobilized to slide in the sliding groove 9 through the meshing of the gear 19 and the toothed plate 17. At this time, the sliding positioning member 10 can contact the crawler on the machine body 1 and position it, so that the crawler can be located at the central position of the machine body 1. When the two threaded columns 11 rotate, they can drive the sleeve 12 to descend, so that the sleeve 12 can drive the rubber pad 7 to contact the crawler. By installing the spring 8, the clamping force can be buffered, so that it can clamp the crawler flexibly. And through the cooperation of installing the threaded barrel 3, the threaded rod 4 and the sliding positioning member 10, crawlers of different sizes can be positioned and clamped, which is convenient for repairing the crawler, thereby improving the overall practicability.
