Embodiment 1

[0042] Figure 1 to Figure 4It is the related drawings of this embodiment. As shown in the figure, this embodiment discloses a follower frame of a rotary drilling rig. The follower frame includes a frame body 1 and slewing bearings arranged at both ends of the frame body 1 2 and sliding lug 3, the outer ring 22 of the slewing bearing 2 is fixedly connected with the drill pipe 5 of the rotary drilling rig through bolts 221, the inner ring 21 of the slewing bearing 2 is fixed on the frame body 1, and the frame body 1 is also equipped with a The rotation restricting device restricts the relative rotation of the outer ring 22 and the frame body 1 . In this embodiment, the rotation restraining device is a latch device 4 that can selectively catch the bolt 221. The latch device 4 includes a guide rail 42, a latch 41 and a locking screw. The guide rail 42 includes two parallel shafts fixed on the main body. Plate-shaped structure, strip-shaped holes 421 are provided along its length...

Embodiment 2

[0045] Figure 5 and Image 6 That is the relevant drawings of this embodiment. Compared with Embodiment 1, the rotation restraint device of the follower frame described in this embodiment is different. As shown in the figure, the rotation restraint device in this embodiment is set on the frame The body 1 and the outer circle of the outer ring 22 constitute the set screw device 6 of the friction pair. The set screw device 6 includes a mounting seat 61 and a set screw 62, the mounting seat 61 is an arc-shaped block structure fixedly arranged on the frame body 1, and the mounting seat 61 is provided with a screw corresponding to the set screw 62. The set screw 62 is screwed into the screw hole and passes through the screw hole against the outer circle of the outer ring 22 . The operator can lock the outer ring 22 by turning the set screw 62 to limit the relative rotation between the outer ring 22 and the follower frame, or disengage from the outer circle of the outer ring 22 t...

Embodiment 3

[0049] Figure 7 to Figure 12 That is the relevant drawings of this embodiment. Compared with Embodiment 1, this embodiment differs in that the rotation restraint device is different. As shown in the figure, the rotation restraint device in this embodiment is arranged on the frame body 1 and the outer The upper end surface of the ring 22 constitutes the pressure plate device 7 of the friction pair. The pressing plate device 7 includes a pressing plate 71 hinged on the frame body 1 and a driving bolt 72 for driving the pressing plate 71 to be tightly pressed against the end surface of the outer ring 22 .

[0050] In this embodiment, there are three ways to connect the pressing plate 71 and the driving bolt 72:

[0051] First, the middle part of the pressure plate 71 is hinged on the frame body 1 through the hinge point 75, one end of the pressure plate 71 rests on the end face of the outer ring 22, the other end of the pressure plate 71 is connected with the driving bolt 72, t...

Abstract

The invention provides a rotary drilling rig and a follow-up rack thereof. The follow-up rack of the rotary drilling rig comprises a rack body, as well as a revolving bearing and a sliding lug which are respectively arranged at two ends of the rack body; the outer ring of the revolving bearing is fixedly connected with a drill rod of the rotary drilling rig; the inner ring of the revolving bearing is fixedly arranged on the rack body; and the follow-up rack further comprises a revolving restriction device used for restricting the relative rotation between the outer ring and the rack body. The follow-up rack is provided with the revolving restriction device which can be used for effectively controlling the revolution DOF (Degree Of Freedom) of the follow-up rack relative to the drill rod, so that operating personnel can accurately control the in-place angle of the sliding lug of the follow-up rack by virtue of controlling a square head at the lower end of the drill rod in the process of inserting the drill rod into the power head, so that the difficulty in adjusting the in-place angle of the sliding lug of the follow-up rack is greatly reduced, the misoperation in the drill rod disassembly and assembly process is reduced, and the drill rod disassembly and assembly efficiency is improved.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a rotary drilling rig and a traveling frame thereof. Background technique [0002] The follower frame of the rotary drilling rig is an auxiliary device for the work of the drill pipe. One end of it is equipped with a rotary support and is set on the drill pipe, which acts as a rotary support for the drill pipe. The sliding lug forms a sliding connection with the guide rails on both sides of the mast, and slides up and down within the effective length of the mast to ensure the verticality of the drill pipe when it is working. When installing the drill pipe on the rotary drilling rig, firstly assemble the drill pipe on the ground, connect the slewing support of the follower frame with the flange at the upper end of the drill pipe, and open the sliding lugs of the follower frame to both sides, and then Connect the flat head at the upper end of the drill pipe to the lifter, ere...
