The invention discloses a walking device of a rotary drilling rig. A driving wheel is arranged at the front end of a main vehicle frame, a guide wheel is arranged at the rear end of the main vehicle frame, the driving wheel and the guide wheel are connected through a crawler belt, a supporting chain wheel and a supporting wheel are arranged between the upper side of the main vehicle frame and thecrawler belt, and a thrust wheel is arranged between the lower side of the main vehicle frame and the crawler belt. Power of the driving motor is transmitted to the crawler belt through the driving wheel, movement of the whole rotary drilling rig is guaranteed, the supporting chain wheel achieves gentle movement of the whole rotary drilling rig through relative movement of the upper crawler belt and the lower crawler belt, the crawler belt of the rotary drilling rig can conduct drilling operation within any angle range in the direction of the crawler belt, maneuverability and flexibility are achieved, and the site adaptability is high. The stability and comfort of the whole machine during construction can be improved, construction and transportation are convenient, and the device has the advantages of being simple in structure, convenient to produce and prepare, low in cost, long in service life and low in failure rate.

    本发明公开了一种旋挖钻机的行走装置,在主车架的前端设置有驱动轮、后端设置有引导轮,驱动轮和引导轮通过履带联接,主车架上侧与履带之间设置有托链轮和支撑轮,主车架下侧与履带之间设置有支重轮。本发明通过驱动轮将驱动马达的动力传递给履带,确保整个旋挖钻机运动,托链轮依靠上、下履带的相对运动来实现整个旋挖钻机的平缓移动,旋挖钻机的履带可以在顺着履带方向任意角度范围内进行钻孔作业,机动灵活、场地适应能力强。本发明能够提高施工时整机的稳定性和舒适性,且便于施工和运输,具有结构简单、便于生产制备、成本较低,使用寿命长、故障率低的优点。
