Deviation-preventing suspension device

An anti-deviation suspension device relates to the technical field of petroleum mechanical equipment and comprises an outer sleeve, a center rod, a drill bit and a drill rod, the center rod is arranged in the outer sleeve, the bottom of the center rod is connected with the drill rod through a screw, the bottom end of the drill rod is connected with the drill bit, and a righting mechanism is arranged outside the drill rod and comprises a door-shaped supporting frame and righting rollers. The door-shaped support is fixedly connected with the inner wall of the outer sleeve, the door-shaped support is sleeved with the righting idler wheel, the righting idler wheel is connected with the door-shaped support in a sliding mode, and the righting idler wheel makes contact with the drill rod. The anti-deviation suspension device can prevent eccentric wear, shock absorption and tripping of the sucker rod, and integrated application of the digital load sensor is achieved. 一种防偏悬挂装置，涉及石油机械设备技术领域，它包括外套管、中心杆、钻头和钻杆，外套管内设有中心杆，中
