Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3The utility model provides a technical solution: a locking device for a sleeper bolt drilling vehicle, comprising two symmetrically arranged cylinders 1 and a sleeve 3 located at the telescopic end of the cylinder 1, the telescopic end of the cylinder 1 is rotatably provided with a connecting ring 5 movably inserted into the sleeve 3, the side of the connecting ring 5 is provided with two symmetrically arranged connecting rods 51, the peripheral side of the sleeve 3 is provided with a guide hole 31 for guiding the connecting rod 51, and the outer peripheral side of the sleeve 3 is movably sleeved with an outer ring 52 connected to the connecting rod 51, the side of the outer ring 52 is provided with a mounting plate 6, and a positioning plate 7 is installed on the mounting plate 6. The cylinder 1 pushes the connecting ring 5 to move, and the connecting ring 5 pushes the outer ring 52, the mounting plate 6 and the positioning plate 7 to move through the connecting rod 51. During the movement of the connecting rod 51 along the guide hole 31, the outer ring 52, the mounting plate 6 and the positioning plate 7 are driven to realize horizontal movement, rotation and secondary horizontal movement, so that the positioning plate 7 contacts and squeezes onto the train track, thereby completing the locking of the drilling vehicle.

[0019] Furthermore, the fixed ends of the two cylinders 1 are fixedly connected by bolts, and a mounting seat 2 is installed at the fixed end of the cylinder 1, so that the two cylinders 1 play a reverse thrust role on each other.

[0021] Furthermore, when the connecting rod 51 moves along the guide hole 31 , the connecting rod 51 can rotate at least ninety degrees around the axis of the sleeve 3 , the two ends of the guide hole 31 are strip structures, and the middle of the guide hole 31 is a spiral structure distributed around the side of the sleeve 3 .

[0022] Furthermore, the positioning plate 7 is mounted on the mounting plate 6 by means of bolts, and the bolt heads are sunken in the grooves on the positioning plate 7 to prevent the bolts from contacting the sleepers, thereby increasing the friction between the positioning plate 7 and the sleepers.

[0023] Furthermore, the positioning plate 7 is an insulating plate, and a PVC plate may be used.

[0024] When using:

[0025] The mounting base 2 and the fixing base 4 are mounted on the drilling vehicle. When the drilling vehicle is moved to an appropriate position, the cylinder 1 is controlled to extend. The cylinder 1 pushes the connecting ring 5 to move. The connecting ring 5 pushes the outer ring 52, the mounting plate 6 and the positioning plate 7 to move through the connecting rod 51. The connecting rod 51 moves along the guide hole 31, driving the outer ring 52, the mounting plate 6 and the positioning plate 7 to achieve horizontal movement, rotation and secondary horizontal movement, so that the positioning plate 7 contacts and squeezes onto the train track, thereby completing the locking of the drilling vehicle.
