Disclosed is a walker-type rotary drilling rig; a slewing bearing (8) is mounted below a main machine body (14); a bearing mount (19) is connected to a fixed travel frame (6); the bearing mount (19) is connected to a longitudinal connecting beam (9) by means of a pin (16); the longitudinal connecting beam (9) and the frame cylinder outer sliding sleeves (21) at the two ends are fixed to form a mobile traveling support frame; one end of the frame cylinder (12) is connected to the frame cylinder outer sliding sleeve (21), and the other end is connected to the frame cylinder inner sliding sleeve (13) and the wheel frame (10) by means of a wheel frame shaft (18); a supporting wheel (20) is mounted on a wheel frame (10); the supporting wheel (20) travels forward and backward on a slideway (11) mounted in a mobile traveling frame (5); the mobile traveling frame (5) and the mobile traveling support frame are connected by means of a longitudinal traveling cylinder (7). Dozer blades (23) are added at the front and rear of the chassis to facilitate the travel of the rotary drilling rig over road sections having potholes. The walker-type chassis constituted by the described components greatly improves the stability of rotary drilling rigs. |
