Embodiment 1

[0050] Such as Figure 5As shown, the present embodiment provides a rubbing rod head, comprising a motor 11, a first gear mounted on the shaft of the motor 11, two rubbing wheels 12, and a second gear mounted on the shafts of the two rubbing wheels 12 respectively and the third gear; the motor 11 and the two rubbing wheels 12 are parallel to each other, and the first gear meshes with the second gear and the third gear respectively; the first gear, the second gear and the third gear are all installed on the gear In the box 13, and the motor 11 and the rubbing wheel 12 are respectively installed in the gear box 13 both sides.

[0051] In this embodiment, two rubbing wheels 12 are provided with a rubbing frame 14; the rubbing frame 14 includes two parallel fixed plates 141 and a connecting rod 142, and the connecting rod 142 and the two rubbing wheels 12 are installed vertically. Between the two fixing plates 141 ; one of the fixing plates 141 fits a side wall of the gear box 13...

Embodiment 2

[0054] Such as Figure 1 to Figure 7 As shown, the present embodiment provides a rod rubbing device for a power head drilling machine in a coal mine. The power head drilling machine in this embodiment is a main shaft through-hole type power head drilling machine, and the device includes two rubbing rods described in Embodiment 1. The head is used for clamping and driving the drill pipe to rotate, and also includes a clamping unit 2 installed under the two rubbing rod heads 1, a carriage 3 and an integrated valve group 5 for installing and supporting the clamping unit 2; The rubbing wheels 12 of each rubbing rod head 1 are relatively arranged and are all parallel to each other, and the plane where the two rubbing wheels 12 of the same rubbing rod head 1 is parallel to the plane where the two rubbing wheels 12 of another rubbing rod head 1 is located; the clamping unit 2 Including the center plate, the center plate is respectively connected with the left side plate and the right...

Embodiment 3

[0066] This embodiment also provides a tripping method matched with the rod rubbing device, wherein, as Figure 7 As shown, the tripping equipment matched with the rod rubbing device is conventional equipment, and the tripping equipment matched with the rod rubbing device includes: a lifting arm 6 for hoisting the drill rod 71, for storing The drill rod frame 7 of the drill rod 71, the drill power head 8 and the clamper 10, and the power head 8 and the clamper 10 are coaxially installed on the feed body 9; the installation base 31 of the rod rubbing device is installed on Feed the end of the fuselage 9, so that the rod rubbing device, the power head and the holder are installed coaxially in sequence, more specifically, the drill rod 71 clamped between the two rubbing rod heads 1 of the rod rubbing device and the power The drill rod 71 clamped by the head 8 is arranged coaxially.

[0067] The drilling method supporting the rod rubbing device includes the following three steps:...

Abstract

The invention discloses rod rubbing heads, a rod rubbing device for a coal mine underground power head drilling machine and a tripping method. The rod rubbing device comprises the two rod rubbing heads, a clamping unit mounted on the lower parts of the two rod rubbing heads, a sliding frame and an integrated valve set; rubbing wheels of the two rod rubbing heads are oppositely arranged and are parallel mutually; the clamping unit comprises a central plate, and the central plate is connected with a left side plate and a right side plate which are located on the two sides of the central plate; the two rod rubbing heads are mounted at the upper ends of the left side plate and the right side plate correspondingly; the sliding frame comprises a mounting base, a positioning plate and sliding rails vertically mounted between the mounting base and the positioning plate, wherein the mounting base and the positioning plate are parallel mutually; the sliding rails penetrate through the central plate and are parallel to the rubbing wheels of the rod rubbing heads; and the integrated valve set is connected with the rod rubbing heads and the clamping units through wires correspondingly. The rotating speed of a drill rod driven by the rod rubbing device is 2-4 times the rotating speed of the drill rod driven by a power head; and by arranging the integrated valve set, the rotating speed and the axial moving speed of the drill rod are matched, and thus the rod rubbing device is adaptable to different specifications of drill rods.

Description

technical field [0001] The invention belongs to the technical field of underground drilling in coal mines, and in particular relates to a rubbing rod head, a rod rubbing device for an underground coal mine power head drilling rig and a tripping method. Background technique [0002] A large number of main shaft through-hole type power head drilling rigs are used in the construction of gas drainage drilling or water exploration and drainage in underground coal mines. The length of the drill pipe used for this type of drilling rig is not limited by the stroke of the drilling rig feeding body, and the construction process starts. The drilling process is usually carried out at the rear end of the power head and is done manually. The specific process is as follows: (1) Drilling in process: Manually transport the drill pipe to the rear end of the power head, align the male threaded thread of the drill pipe to be added with the female threaded thread of the drill pipe in the power h...
