Abstract

The invention discloses a follow-up frame of a rotary drilling rig. The follow-up frame comprises a follow-up frame body, a rotary supporter, two connecting arms and a wear-resistant contact plate, wherein a U-shaped chute in longitudinal distribution is formed in each connecting arm; a clamp groove in longitudinal distribution is formed in each of three inner wall surfaces of the chute; the transverse cross section of each clamp groove is in a T shape; at least one end of the upper end and the lower end of each clamp groove penetrates through the end part of the chute to form an opening; a cover plate used for covering the opening of each clamp groove is arranged on the chute; a T-shaped seat corresponding to the clamp groove is arranged at the back part of the wear-resistant contact plate; and each inner wall surface and the wear-resistant contact plate are in matched connection through the clamp groove and the T-shaped seat. The inner wall surface of the chute is connected with theT-shaped seat of the wear-resistant contact plate through the T-shaped clamp groove, so that the damage cannot easily occur; the service life of the follow-up frame is prolonged; and the work stability of the rotary drilling rig is ensured.

Description

technical field [0001] The invention relates to the field of rotary drilling rigs, in particular to a traveling frame of the rotary drilling rig. Background technique [0002] Rotary drilling rigs have high power, strong power and fast hole formation, and are widely used in engineering and building foundation construction. The rotary drilling rig is composed of a crawler chassis, a boarding part, a mast assembly, a drilling system and a hydraulic system. The crawler chassis is used for moving, and the boarding part and others are used for drilling operations. Drill rods in the drilling system of common rotary drilling rigs generally adopt a structure with a traveling frame to ensure the verticality of the borehole during the drilling, lifting and lowering of the rotary drilling rig. One end of the follower frame is connected to the drill pipe through the slewing support, and the other end is sleeved on both sides of the guide rail set on the mast through the chute of the tw...
