Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 and 2, a sliding groove mechanism of a following frame of a rotary drilling rig comprises a following frame 1, a connecting arm 2, a guide rail 3 and a sliding groove 4, wherein a plurality of shock absorbers 5 are mounted on the side surface of the joint of the guide rail 3 and the sliding groove 4 through countersunk screws, each shock absorber 5 comprises a rubber block 5.1, a spring 5.2 and a stress column 5.3, a cylindrical through hole is formed in the middle of the rubber block 5.1, the stress column 5.3 is sleeved on the through hole, two inclined holes which are communicated with the through hole are formed in the front, the rear, the left and the right four surfaces of the rubber block 5.1, the springs 5.2 are mounted on the inclined holes, one end of each spring 5.2 is abutted against the stress column 5.3, the other end of each spring is 3mm-5mm higher than each surface, and the included angle between the inclined holes is 70 °. The shock absorber 5 is arranged on the sliding groove 4 and attached to the guide rail 3. The stress column 5.3 is of an I-shaped structure, the diameters of the top covers at the two ends of the stress column 5.3 are consistent with the diameter of the through hole, and the diameter of the lower end of the stress column 5.3 is smaller than the diameter of the through hole by 0.1 mm.
