Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8 The present invention provides a technical solution: a novel drill pipe guiding device, comprising a base plate 1, on which baffles 2 are symmetrically fixed, and the baffles 2 contact with a first arc-shaped seat 3 and a second arc-shaped seat 4 to achieve positioning. The first arc-shaped seat 3 and the second arc-shaped seat 4 are fixed to the base plate 1 by bolts, and the first arc-shaped seat 3 and the second arc-shaped seat 4 are locked together by a transverse screw. The first arc-shaped seat 3 and the second arc-shaped seat 4 cooperate to achieve clamping and limiting of a steel spacer 5. The steel spacer 5 is symmetrically fixed with positioning rings 501, and the positioning rings 501 contact with the first arc-shaped seat 3 and the second arc-shaped seat 4 to achieve positioning. The steel spacer 5 is locked with the first arc-shaped seat 3 and the second arc-shaped seat 4 by a pin 502.

[0020] A protrusion 301 is fixed on the first arc-shaped seat 3, and a groove 401 is provided on the second arc-shaped seat 4. The groove 401 engages with the protrusion 301 to achieve a positioning function. A fixing box 6 is fixed to the positioning ring 501 on the rear side of the steel spacer 5 by bolts. A slag removal mechanism 7 for cleaning the surface of the drill rod is installed on the fixing box 6, and a lubrication mechanism 8 for lubricating the steel spacer 5 and the drill rod is installed inside the fixing box 6. When using this new drill pipe guiding device, such as Figures 1-8 As shown, the entire device is first installed and fixed to the tunneling drilling rig via the base plate 1, and the drill rod passes through the fixing box 6 and the steel spacer 5. At this time, the cleaning brush 704 contacts the drill rod. Through the sliding action between the drill rod and the steel spacer 5 (the drill rod moves from back to front to realize the drilling operation, that is, the fixing box 6 is located on the side away from the drill bit), the drill rod can be guided and positioned to meet the actual drilling requirements. The slag removal mechanism 7 includes two partitions 701 fixed inside the fixed box 6, and guide grooves 702 are provided on the opposite side of each partition 701. An installation sleeve 703 is nested on the rear partition 701. Several cleaning brushes 704 are fixed at equal angles inside the installation sleeve 703, and several slag discharge holes 705 are provided at equal angles on the installation sleeve 703, with the slag discharge holes 705 and cleaning brushes 704 staggered. A toothed ring 706 is also fixed on the installation sleeve 703, and the toothed ring 706 is positioned in the two guide grooves 702. Between 2, and the toothed ring 706 is symmetrically fixed with convex shafts 707 front and back, and several convex shafts 707 are distributed at equal angles about the center of the toothed ring 706. The convex shafts 707 and the guide groove 702 are slidably connected; the toothed ring 706 meshes with the rack 708 to realize transmission, and the rack 708 is fixed with a slide rod 709, and the slide rod 709 is slidably connected with the fixed box 6. The rack 708 and the fixed box 6 are also fixed with a first spring 710, and the first spring 710 is symmetrically distributed about the center line of the rack 708. During drilling, the drill bit causes significant vibration as it breaks up the rock. This vibration is transmitted through the drill rod to the steel spacer 5 and the fixed box 6, causing them to vibrate. Simultaneously, the rack 708 vibrates under the force of the vibration. Combined with the sliding guide action between the slide rod 709 and the fixed box 6, and the elastic action of the first spring 710, the rack 708 moves up and down under the vibration force. As the rack 708 moves, the meshing transmission between it and the gear ring 706 causes the gear ring 706 to deflect at a certain angle, which, in conjunction with the cam shaft 7... The guiding sliding action between 07 and the guide groove 702 can ensure the stability of the deflection movement of the toothed ring 706. When the toothed ring 706 is deflected under force, it simultaneously drives the mounting sleeve 703 and the cleaning brush 704 to deflect at a certain angle. Through the action of the cleaning brush 704, the debris adhering to the surface of the drill rod can be cleaned. Since the cleaning brush 704 is located behind the steel spacer 5, it can ensure that the debris on the surface of the drill rod is cleaned before entering the steel spacer 5 for guidance. In this way, by cleaning the debris on the surface of the drill rod, the adhesion of the debris on the surface of the drill rod can be avoided, which would increase the friction between the drill rod and the steel spacer 5, and effectively extend the service life of the steel spacer 5. The lubrication mechanism 8 includes a lubricating oil box 801 fixed inside the fixed box 6. The lubricating oil box 801 has an inlet 802 that penetrates the fixed box 6 connected to its upper side, and an outlet 803 fixed to its lower side. The outlet 803 is located directly above the central axis of the steel spacer 5. The outlet 803 cooperates with the sealing plate 804 to achieve a sealing effect. A guide rod 805 is fixed on the sealing plate 804, and the guide rod 805 is slidably connected to the bracket 806. The bracket 806 is fixed inside the fixed box 6. The sealing plate 804 is fixed to one end of the second spring 807, and the other end of the second spring 807 is fixed inside the fixed box 6. During the use of the device, when the fixed box 6 vibrates during drilling, it synchronously drives the sealing plate 804 inside the lubricating oil box 801 to vibrate. Combined with the sliding action between the guide rod 805 and the bracket 806 and the elastic action of the second spring 807, the sealing plate 804 moves up and down under the vibration force. When the sealing plate 804 moves up and separates from the outlet 803, the lubricating oil in the lubricating oil box 801 drips onto the drill rod through the outlet 803. Since the outlet 803 is located behind the steel spacer 5, the lubricating oil drips onto the drill rod first. The drill rod then cooperates with the steel spacer 5 for guidance. Through the rotation of the drill rod, the lubricating oil on the drill rod can fully contact the steel spacer 5, thereby achieving lubrication between the steel spacer 5 and the drill rod, further reducing the friction between the steel spacer 5 and the drill rod, and thus further extending the service life of the steel spacer 5 to better meet the actual use requirements.
