During drilling operations, ordinary small wheels are easily damaged by the impact force of the drilling rig, which also affects the stability of the drilling rig. Therefore, a mobile device for the anchor drilling rig is proposed. Utility Model Content

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, a mobile device for an anchor drilling rig includes a base plate 1, on which a mobile component 2 is provided, and the mobile component 2 provides the base plate 1 with a mobile capability;

[0026] like Figure 2 As shown, the mobile assembly 2 includes a lifting frame 21 located above the base plate 1 and capable of being raised and lowered. Four fixing rods 23 are provided at the lower end of the lifting frame 21. The four fixing rods 23 vertically penetrate the base plate 1. In addition, a universal wheel 24 is provided at the lower end of each of the four fixing rods 23. By controlling the lifting frame 21 to descend, the four universal wheels 24 can simultaneously contact the ground, thereby realizing the movement and steering of the mobile device on the roadway ground.

[0027] In this embodiment, a hydraulic cylinder 22 is fixed on the base plate 1, and the end of the driving shaft of the hydraulic cylinder 22 is fixed to the lifting frame 21. Under the drive of the hydraulic cylinder 22, the lifting frame 21 performs a lifting action; of course, the method of driving the lifting frame 21 to move up and down includes but is not limited to the hydraulic cylinder 22 in this embodiment. In some embodiments, the lifting frame 21 can also be directly driven to move up and down by arranging linear driving components such as cylinders and telescopic rods on the base plate 1.

[0028] Furthermore, in some embodiments, the number of the fixing rods 23 at the lower end of the lifting frame 21 may be more than four, and the number of the universal wheels 24 is the same as that of the fixing rods 23 and may also be more than four.

[0029] Two support assemblies 3 are provided on the base plate 1. The support assemblies 3 include a lifting rod 35 that can be raised and lowered. A support plate 36 is fixed to the lower end of the lifting rod 35. By controlling the lifting rod 35 to descend, the two support plates 36 are brought into contact with the tunnel ground, thereby supporting the mobile device. By controlling the universal wheel 24 to rise and suspend it above the tunnel ground, the universal wheel is prevented from being damaged by impact during drilling operations.

[0030] In this embodiment, the support assembly 3 further includes a first rack 31 fixed to the lifting frame 21, a first fixing plate 32 fixed to the upper end of the base plate 1, a rotating shaft 33 rotatably connected to the first fixing plate 32, a gear 34 fixed to the rotating shaft 33, a lifting rod 35 vertically passes through the base plate 1 and is slidably connected thereto, a second rack 351 is provided at the upper end of the lifting rod 35, the gear 34 is located between the first rack 31 and the second rack 351 and simultaneously meshes with the first rack 31 and the second rack 351, thereby achieving synchronous reverse movement of the lifting rod 35 and the lifting frame 21; so that when the universal wheel 24 rises, the support plate 36 descends and contacts the ground, thereby achieving suspension protection for the universal wheel;

[0031] Of course, the method of controlling the lifting of the lifting rod 35 includes but is not limited to the gear rack structure in this embodiment. In some embodiments, the lifting rod 35 can also be directly driven to move up and down by setting linear drive components such as cylinders and telescopic rods.

[0032] A push rod assembly 4 is provided on opposite sides of the bottom plate 1. The two push rod assemblies 4 can be fixed tightly to the two sides of the tunnel respectively to fix the bottom plate 1. During the drilling operation, the support function of the support plate 36 is combined to improve the stability of the drilling process and prevent the universal wheel 24 from being damaged by impact force.

[0033] like Figure 4 As shown, the top rod assembly 4 includes a connecting rod 41, on which is provided a sliding rod 42 that can be slidably adjusted along its length. A top plate 43 is fixed to the end of the sliding rod 42 that faces away from the connecting rod 41. The sliding adjustment of the sliding rod 42 can be controlled to make the top plate 43 press tightly against the side of the tunnel.

[0034] In this embodiment, the sliding rod 42 is slidably connected to the connecting rod 41, and the sliding direction is parallel to the length direction of the connecting rod 41; two second fixing plates 411 are provided on the connecting rod 41, and a screw rod 44 is rotatably connected between the two second fixing plates 411. A third fixing plate 421 is provided on the sliding rod 42, and the screw rod 44 passes through the third fixing plate 421 and is threadedly connected thereto. By providing a motor on one of the second fixing plates 411 to drive the screw rod 44 to rotate, the sliding position of the sliding rod 42 can be adjusted;

[0035] Furthermore, in order to ensure the stability of the pressing force between the top plate 43 and the side of the tunnel, the screw rod 44 needs to have self-locking properties, that is, the thread lead angle of the screw rod 44 is smaller than the equivalent friction angle.

[0036] Of course, the method of driving the sliding rod 42 to slide and adjust includes but is not limited to the structure such as the screw rod 44 in this embodiment. In some embodiments, the sliding rod 42 can also be directly driven to slide and adjust by setting linear driving components such as cylinders and telescopic rods.

[0037] In this embodiment, a mounting plate 11 is provided on both sides of the base plate 1, and a driving motor 5 is fixed on each of the two mounting plates 11. The driving shafts of the two driving motors 5 are respectively fixed to the connecting rods 41 on the two top rod assemblies 4, and can drive the connecting rods 41 to rotate; thereby facilitating the control of the connecting rods 41 to rotate toward the side of the base plate 1 during the movement of the anchor drilling rig, thereby reducing the space occupied by the top rod assembly 4 and facilitating movement in the tunnel.

[0038] Before drilling, the base plate 1 is first moved (the universal wheel 24 is in contact with the ground) to the specified position; then the two push rod assemblies 4 are controlled to rotate to be perpendicular to the side of the base plate 1, and the top plates 43 of the two push rod assemblies 4 are controlled to be tightly pressed against the two side walls of the respective tunnels to fix the position of the base plate 1; thereafter, under the drive of the hydraulic cylinder 22, the lifting frame 21 rises and the lifting rod 35 descends, so that the support plate 36 is in contact with the tunnel ground, and the universal wheel 24 is suspended in the air; thereby, during the subsequent drilling operation, the universal wheel 24 will not be damaged by the impact force, and the stability of the drilling action is guaranteed.

[0039] Working principle:

[0040] By providing a moving assembly 2 and a support assembly 3 on the base plate 1, the universal wheel 24 and the support plate 36 can be raised and lowered. During drilling, the universal wheel 24 rises off the tunnel surface, while the support plate 36 descends to contact the ground for support, preventing damage to the universal wheel 24 from impact during drilling. By providing a push rod assembly 4 on either side of the base plate 1 and providing a telescopically slidable sliding rod 42 within the push rod assembly 4, the top plate 43 is pressed against the side of the tunnel, limiting the displacement of the base plate 1. This, combined with the support provided by the support plate 26, improves the stability of the drilling process.
