[0039] Embodiment one
[0040] The present embodiment relates to a drilling machine posture adjusting device to improve the flexibility of airborne drilling machine drilling construction.
[0041] Overall structure, as shown in Figure 1 and Figure 2 The drilling machine posture adjusting device is used to adjust the drilling position of the drilling machine body 1, and the drilling machine posture adjusting device comprises a base 2, a carrier 3 carrying the drilling machine body 1, and an adjusting part 4 arranged between the base 2 and the carrier 3. The adjusting part 4 adjusts the orientation of the drilling machine body 1. The adjusting part 4 comprises a rotating adjusting part 401 and an inclination adjusting part 402; the rotating adjusting part 401 is connected to the base 2 to constitute the relative rotation of the carrier 3 and the base 2. The inclination adjusting part 402 is connected between the rotating adjusting part 401 and the carrier 3, and the inclination adjusting part 402 adjusts the inclination θ between the carrier 3 and the rotation axis L.
[0042] By connecting the drilling machine body 1 to the carrier 3, the orientation of the drilling machine body 1 can be adjusted by rotating the rotation adjusting part 401 during drilling, the height of the drill bit end of the drilling machine body 1 can be adjusted by the inclination adjusting part 402, and the multi-degree-of-freedom composite angle adjustment of the drill bit end of the drilling machine body 1 can be realized by the cooperation of the inclination adjusting part 402 and the rotation adjusting part 401, thereby helping to improve the flexibility of the airborne drilling machine in drilling construction.
[0043] Based on the above overall introduction, as shown in Figure 1 The base 2 is used to carry the adjusting part 4 and fix the drilling machine posture adjusting device on the tunneling equipment or the continuous mining equipment. Specifically, as an optional embodiment of the base 2, one side of the base 2 connected to the adjusting part 4 is flat, and the other side of the base 2 can be shaped to the continuous mining equipment, so as to fix the base 2 on the continuous mining equipment. Meanwhile, the rotation axis L of the carrier 3 is perpendicular to the base 2, that is, the rotation axis L is perpendicular to the plane of the base.
[0044] It can be understood that, as an optional embodiment of the rotation adjusting part 401, in the embodiment, as shown in Figures 1 to 3 The rotation adjusting part 401 includes a slewing bearing 4011 fixed to the base 2, a driving gear 4012 driving the slewing bearing 4011, and a driving motor 4013 driving the driving gear 4012 to rotate; the fixed end of the slewing bearing 4011 is connected to the base 2, and the rotating end of the slewing bearing 4011 is connected to the inclination adjusting part 402.
[0045] When the orientation of the drilling machine body 1 is adjusted by using the rotation adjusting part 401, the driving motor 4013 is started, the driving motor 4013 drives the driving gear 4012 to rotate, and then the rotating end of the slewing bearing 4011 rotates, thereby driving the inclination adjusting part 402 and the driving motor 4013 to move.
[0046] It is worth noting that, specifically, as an optional embodiment of the slewing bearing 4011, in the present application, the slewing bearing 4011 is of an external tooth type, and thus it can be understood that the inner ring 4011a of the slewing bearing 4011 is the fixed end, and the outer ring 4011b of the slewing bearing 4011 is the rotating end. The teeth of the slewing bearing 4011 are fixed to the outer wall of the outer ring 4011b and mesh with the driving gear 4012, and the inner ring 4011a of the slewing bearing 4011 is connected to the base 2.
[0047] By setting the rotary adjusting part 401 to include the slewing bearing 4011, the drilling rig posture adjusting device has good load capacity while being able to adjust the orientation of the drilling rig body 1, thereby helping to improve the use stability of the drilling rig posture adjusting device. By setting the driving gear 4012 and the driving motor 4013, the slewing bearing 4011 can be controlled and adjusted to rotate, thereby eliminating the need for manual driving of the slewing bearing 4011 to rotate, and helping to improve the use convenience of the drilling rig posture adjusting device.
[0048] As an optional embodiment of the inclination adjusting part 402, as shown in Figure 1 and Figure 4 , the inclination adjusting part 402 includes a follower plate 4021, a support plate 4022 and a first telescopic part 4023. The follower plate 4021 is connected with the rotary adjusting part 401, the support plate 4022 is fixedly connected with the follower plate 4021 and hinged with the carrier 3, and the support plate 4022 separates the carrier 3 from the follower plate 4021. The first telescopic part 4023 is hinged with the follower plate 4021 and the carrier 3 at two ends respectively, and the first telescopic part 4023 is extended or contracted to adjust the inclination angle θ.
[0049] It can be understood that, on the basis that the rotary adjusting part 401 is provided with a fixed end and a rotating end, the follower plate 4021 is connected with the rotating end of the slewing bearing 4011, that is, the follower plate 4021 is connected with the outer ring 4011b of the slewing bearing 4011, and when the outer ring 4011b of the slewing bearing 4011 rotates, the entire inclination adjusting part 402 will rotate.
[0050] By controlling the first telescopic part 4023 to be extended or contracted, the inclination angle θ is adjusted, and the height of the drilling end of the drilling rig body 1 is adjusted. In combination with the rotary adjusting part 401, the inclination adjusting part 402 is used to realize multi-degree-of-freedom composite angle adjustment of the drilling rig body 1, thereby helping to improve the drilling flexibility of the airborne drilling rig. As an optional embodiment of the first telescopic part 4023, the first telescopic part 4023 is selected to be a pneumatic cylinder or a hydraulic cylinder, and in the embodiment, the hydraulic cylinder is selected as the first telescopic part 4023.
[0051] In order to improve the stability of the inclination adjusting part 402, as shown in Figure 4 , two groups of the support plate 4022 and the first telescopic part 4023 are arranged along the width direction of the carrier 3. That is, two groups of the support plate 4022 and the first telescopic part 4023 are arranged along the direction perpendicular to the rotation axis L and perpendicular to the drilling direction of the drilling rig body 1. By arranging two groups of the first telescopic part 4023, the inclination of the carrier 3 caused by active adjustment can be effectively prevented.
[0052] As an optional embodiment of the carrier 3, as shown in Figure 1 and Figure 5As shown, the setting carrier 3 includes a connecting plate 301, a bearing plate 302 and a second telescopic piece 303; the connecting plate 301 is connected with the inclination adjusting piece 402; the bearing plate 302 is arranged on the connecting plate 301 and slides along the drilling direction of the drilling rig body 1; the second telescopic piece 303 connects the connecting plate 301 and the bearing plate 302 and adjusts and locks the relative position of the connecting plate 301 and the bearing plate 302.
[0053] Based on the above overall introduction, when the connecting plate 301 is connected with the inclination adjusting piece 402, specifically, on the basis that the inclination adjusting piece 402 includes a support plate 4022 and a first telescopic piece 4023, the connecting plate 301 is hinged with the support plate 4022, and the two ends of the first telescopic piece 4023 are respectively hinged with the follow-up plate 4021 and the connecting plate 301. At the same time, the drilling rig body 1 is fixed on the bearing plate 302. In this way, by adjusting the orientation and inclination angle of the connecting plate 301, the orientation and inclination angle of the drilling rig body 1 are realized.
[0054] Meanwhile, as an optional embodiment of the second telescopic piece 303, the second telescopic piece 303 can be selected from a gas cylinder, a hydraulic cylinder or an electric push rod, etc. In the present embodiment, the preferred second telescopic piece 303 is selected from a hydraulic cylinder, which is helpful to accurately adjust the relative position of the connecting plate 301 and the bearing plate 302 and lock the relative position between them after adjustment.
[0055] In order to further increase the stability of the relative sliding of the connecting plate 301 and the bearing plate 302, the connecting plate 301 is upwardly folded to form a convex edge 3011, and the bearing plate 302 is provided with a groove 3021 on both sides, and the convex edge 3011 is slidingly inserted into the groove 3021. In this way, the sliding direction of the bearing plate 302 is limited, so that the bearing plate 302 cannot slide in the direction other than the direction in which the groove 3021 is opened, thereby improving the adjustment stability of the carrier 3.
[0056] By arranging the carrier 3 to include the relatively slidable connecting plate 301 and bearing plate 302, the distance between the drilling rig body 1 and the drilling target is facilitated to be adjusted, which is helpful to improve the drilling depth under the condition that the length of the drill rod is constant, and for some shallow holes, it is not necessary to connect a new drill rod.
[0057] The drilling rig posture adjusting device described in the present application embodiment connects the drilling rig body 1 with the carrier 3, and adjusts the orientation of the drilling rig body 1 by rotating the adjusting piece 401 during drilling, or adjusts the height of the drill head end of the drilling rig body 1 by the inclination adjusting piece 402, or realizes multi-degree-of-freedom compound angle adjustment by the cooperation of the inclination adjusting piece 402 and the rotating adjusting piece 401, which is helpful to adjust the drilling position of the drilling rig body 1, and further realizes the flexibility of the airborne drilling rig drilling construction.
[0058] Embodiment two
[0059] The embodiment relates to an airborne drilling machine, which comprises a drilling machine posture adjusting device and a drilling machine body 1 connected to the drilling machine posture adjusting device.
[0060] Specifically, the drilling machine body 1 is connected to the bearing plate 302. As the setting position of the airborne drilling machine, the airborne drilling machine can be optionally arranged on a large arm of the continuous miner.
[0061] By arranging the airborne drilling machine to comprise the drilling machine posture adjusting device and the drilling machine body 1, the multi-degree-of-freedom compound angle adjustment of a drill bit of the drilling machine body 1 can be facilitated, and the flexibility of drilling construction of the airborne drilling machine is improved.
