[0046] In actual use, since there is a certain distance between the piston rod of the left and right swing cylinder 16 and the hinge shaft of the track seat in the left and right direction, the left and right swing cylinder 16 can drive the rear track seat 8 to swing left and right around the hinge shaft of the track seat when it extends and retracts.

[0047] In actual use, the copper plate can effectively reduce the friction between the rear track seat 8 and the intermediate frame 5 during the left and right swinging process.

[0048] In actual use, the left and right pushing cylinder 3 can drive the left and right sliding blocks 2 to slide left and right along the track base 1, thereby adjusting the left and right position of the drilling rig 12. The front and rear swing cylinder 7 drives the intermediate frame 5 to swing back and forth, thereby making the drilling rig lifting assembly and the drilling rig 12 swing back and forth synchronously. The lifting cylinder 11 drives the lifting frame 10 to lift, thereby realizing the lifting of the drilling rig 12. The spiral swing cylinder 13 drives the drilling rig 12 to flip, which can realize the drilling assistance operation. Since the front and rear swing cylinder 7 positions the intermediate frame 5 in the left and right direction, it can keep the intermediate frame 5 stable. Therefore, under the action of the left and right swing cylinder 16, the drilling rig lifting assembly swings left and right around the bottom hinge shaft and slides with the upper sliding groove 15 of the intermediate frame 5.
