detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 , the rotary drilling rig includes a hoisting head 1, a mast 2, a drill pipe 3, a power head 4 and a main body 14 and a walking base. The mast 2 is connected with the main body 14 and is mounted with a hoist 1 and drilled. The rod 3 is driven by a hoist mounted on the main body 14 to lift the wire rope and is rotated by the power head 4. Adding a dozer blade 23 to the front and rear of the chassis facilitates the rotary drilling rig to walk on the pit road.

As shown in FIG. 2, FIG. 3 and FIG. 4, the rotary drilling rig includes a main body 14 and a slewing bearing 8 Connected, the bearing base 19 is connected to the fixed walking leg 6, the bearing base 19 is connected to the longitudinal connecting beam 9 through the connecting pin 16, and the longitudinal connecting beam 9 and the outer leg sliding sleeve 21 at both ends are fixed as a moving walking stand, and the foot cylinder 12 One end is connected to the outer cylinder sliding sleeve 21, and the other end is connected to the inner cylinder of the supporting cylinder. The sliding sleeve 13 is connected to the wheel carrier 10 through the connecting shaft 18. The supporting roller 20 is mounted in the wheel carrier 10, and the supporting roller 20 is moving the walking foot. The glide path 17 in the 5 travels forward and backward, and the moving walking leg 5 is connected to the moving walking leg through the longitudinal traveling cylinder 7. Adding a dozer blade 23 to the front and rear of the chassis facilitates the rotary drilling rig to walk on the pit road.

A slide (pulley) 11 is mounted on the wheel carrier 10 to slide down the upper slide 22 for moving the front, rear, left and right movements of the walking foot 5.

The walking type walking chassis is controlled by a cab mounted on the main body 14. By controlling the expansion and contraction of the foot cylinder 12, the alternate operation of the moving walking foot 5 and the fixed traveling leg 6 and the ground force is adjusted. The front and rear walking and the left and right steering of the rotary drilling rig are achieved by controlling the expansion and contraction of the longitudinal traveling cylinder 7. During the operation of the rotary drilling rig, the moving walking foot 5 and the fixed walking foot 6 can be brought into contact with the ground at the same time to achieve the best stability of the rotary drilling rig.
