[0033] Reference Figures 1 to 3 As shown, a drill rod conveying device for a roof drilling rig according to an embodiment of the utility model comprises: a conveying frame 100 and a walking system 400.

[0034] The conveying frame 100 is provided with a plurality of fixing components 200 at intervals along its length direction. The fixing components 200 include a plurality of supporting parts 210 arranged at intervals along the width direction of the conveying frame 100. The upper end surface of the supporting part 210 is provided with an arc-shaped supporting groove 211 which passes through the width direction of the conveying frame 100. The arc-shaped supporting groove 211 is adapted to the drill rod 300. The arc-shaped supporting groove 211 is used for the drill rod 300 to be embedded. An adjustable limiting part 220 is provided on the supporting part 210. The limiting part 220 is used to abut against the drill rod 300 to limit the displacement of the drill rod 300 along its own axial direction and upward, thereby limiting the drill rod 300 in the arc-shaped supporting groove 211 to prevent the drill rod 300 from being separated from the arc-shaped supporting groove 211 due to vibration during conveyance of the drill rod 300. In some specific embodiments, the fixing assembly 200 includes two support parts 210 , which are respectively located at the two ends of the conveying frame 100 in the width direction. The arc-shaped support groove 211 is a semicircular arc groove. The two support parts 210 are respectively used to support the two ends of the drill rod 300 .

[0035] The walking system 400 includes a track 410, a walking wheel 420 and a driving member 430. The walking wheel 420 is rotatably arranged at the bottom end of the conveying frame 100 and matches the track 410. The driving member 430 is used to drive the walking wheel 420 to rotate so that the walking wheel 420 can travel along the distribution direction of the track 410. In some specific embodiments, there are two tracks 410, which are distributed along the length direction of the conveying frame 100. The two tracks 410 are arranged oppositely along the width direction of the conveying frame 100. There are two groups of walking wheels 420, which are respectively located on opposite sides of the width direction of the conveying frame 100. One group of walking wheels 420 includes a plurality of walking wheels 420 arranged at intervals along the length direction of the conveying frame 100, wherein the peripheral side of the walking wheel 420 is provided with an embedding groove for partially embedding the track 410. It can be understood that the track 410 can be laid between the drill rod storage and the drilling rig equipment.

[0036] When in use, the drill rod 300 is placed from top to bottom in the arc-shaped support groove 211 of the support part 210, and then the limiting part 220 is adjusted so that the limiting part 220 abuts against the drill rod 300 to limit the displacement of the drill rod 300 along its own axial direction and upward, thereby limiting the drill rod 300 in the arc-shaped support groove 211 to achieve the fixation of the drill rod 300. The multiple fixing assemblies 200 are respectively used to fix multiple drill rods 300, and then the driving member 430 is started to drive the walking wheel 420 to rotate through the driving member 430 so that the walking wheel 420 moves along the distribution direction of the track 410, thereby driving the conveying frame 100 to move and convey the drill rod 300. Through the above-mentioned structural setting, the drill rod conveying device for the skydrilling machine of the embodiment of the utility model can convey multiple drill rods 300 at one time, with high automation and high conveying efficiency.

[0037] In some specific embodiments, the driving member 430 is configured as a motor, and one motor may be configured to be connected to one of the running wheels 420, or multiple motors may be configured to be connected to multiple running wheels 420, for example, in this embodiment, four motors are configured to be connected to the four running wheels 420 at the four corners of the conveying frame 100, respectively, so that the driving is stable and reliable. Obviously, the specific number of motors can be selected according to the actual application scenario.

[0038] Reference Figures 1 to 3 As shown, it can be understood that the limiting portion 220 is movably and adjustably arranged on the supporting portion 210 along the length direction of the conveying frame 100, and the limiting portion 220 is provided with an arc-shaped abutting surface 221 adapted to the drill rod 300 on the upper side of the arc-shaped supporting groove 211, and the arc-shaped abutting surface 221 abuts against the outer peripheral wall of the drill rod 300 to limit the displacement of the drill rod 300 along its own axial direction and upward. Specifically, when the arc-shaped abutting surface 221 abuts against the drill rod 300, at least part of it abuts against the upper half of the peripheral wall of the drill rod 300. In this way, a radially inclined downward force of the drill rod 300 can be applied to the drill rod 300 through the arc-shaped abutting surface 221 to limit the upward displacement of the drill rod 300. Obviously, when the arc-shaped abutting surface 221 abuts against the outer peripheral wall of the drill rod 300, friction is generated in the axial direction of the drill rod 300, thereby limiting the axial displacement of the drill rod 300.

[0039] It is conceivable that, in order to improve the limiting effect on the drill rod 300 , an anti-slip pattern may be provided on the arc-shaped abutting surface 221 to increase the friction force.

[0040] Reference Figures 2 to 4 As shown, it can be understood that one support portion 210 is correspondingly provided with two limiting portions 220, the two limiting portions 220 are arranged oppositely along the length direction of the conveying frame 100, and the arc-shaped abutting surface 221 is located at the opposite sides of the two limiting portions 220. The fixing assembly 200 also includes a driving portion, which is in transmission connection with the two limiting portions 220 to drive the two limiting portions 220 to move closer to or away from each other along the length direction of the conveying frame 100 to clamp or release the drill rod 300. Through the above arrangement, the two limiting portions 220 can be used to clamp the drill rod 300 to limit the drill rod 300, and the limiting effect is better. At the same time, the structure is more stable and reliable, and one driving portion is used to drive the two limiting portions 220 to move at the same time, which is convenient and quick to operate. It can be understood that the driving portion can drive the two limiting portions 220 to move away from each other along the length direction of the conveying frame 100 to a position avoiding the vertical access path of the drill rod 300.

[0041] Reference Figure 3 and Figure 4As shown, it can be understood that the driving part includes a driving screw 230 distributed along the length direction of the conveying frame 100, and the driving screw 230 is rotatably arranged on the supporting part 210. The driving screw 230 includes a first thread segment 231 and a second thread segment 232 with opposite rotation directions. The first thread segment 231 and the second thread segment 232 are respectively threadedly connected with two limiting parts 220. A guiding structure is provided between the limiting part 220 and the supporting part 210, which is used to provide guidance for the movement of the limiting part 220 along the length direction of the conveying frame 100. In this way, the driving screw 230 can be rotated to drive the two limiting parts 220 to move closer to or farther from each other along the length direction of the conveying frame 100. The structure is simple and practical. Specifically, the supporting part 210 is provided with detachable supports 214 on opposite sides along the length direction of the conveying frame 100 to rotatably install the two ends of the driving screw 230, and the supporting part 210 is provided with a clearance hole 215 for the driving screw 230 to pass through.

[0042] Reference Figure 3 and Figure 4 As shown, it can be understood that the guiding structure includes a guide rod 212 which is arranged on the supporting part 210 and distributed along the length direction of the conveying frame 100, and a guide hole 222 which is slidably matched with the guide rod 212 is provided on the limiting part 220. Through the cooperation between the guide rod 212 and the guide hole 222, guidance is provided for the movement of the limiting part 220.

[0043] Reference Figure 3 and Figure 4 As shown, it can be understood that a turntable 233 is coaxially fixed at one end of the driving screw 230, and an operating rod 234 is eccentrically provided on the turntable 233. The operator can hold the operating rod 234 to rotate the driving screw 230, thereby manually driving the driving screw 230 to rotate, which has a simple structure and low cost.

[0044] Reference Figures 1 to 3 As shown, it can be understood that the support part 210 is detachably connected to the conveying frame 100, so as to facilitate the replacement of the support part 210. On the one hand, it can not only facilitate the replacement of the support part 210 when it is worn out, but also, for different types of drill rods 300, they can also be matched by replacing the support part 210, thereby improving the application range of the equipment.

[0045] Reference Figures 1 to 3As shown, it can be understood that the conveying rack 100 includes a first connecting rod 101 distributed along its own length direction, and a mounting groove 213 is provided at the bottom end of the support part 210. The mounting groove 213 is distributed along the length direction of the first connecting rod 101 and is open at the bottom end. The mounting groove 213 is used for the first connecting rod 101 to be embedded. A positioning structure is provided between the support part 210 and the first connecting rod 101 for fixing the support part 210. When installing the support part 210, the support part 210 is placed from top to bottom on the first connecting rod 101 so that the first connecting rod 101 is embedded in the mounting groove 213, and then the positioning structure is used to fix the support part 210. When disassembling, the operation can be reversed, and the operation is very convenient. In some specific embodiments, the positioning structure includes a positioning screw 240, which is threadedly installed on the support part 210, and the positioning screw 240 is distributed along the width direction of the first connecting rod 101. The positioning screw 240 is used to abut the side wall of the first connecting rod 101 in the width direction to fix the support part 210. When the support part 210 needs to be removed, the positioning screw 240 can be loosened, and the operation is very convenient. The advantage of such a setting is that the support part 210 can be moved and adjusted along the length direction of the first connecting rod 101. Obviously, when the support part 210 needs to be replaced to adapt to different models of drill rods 300, the size of the arc-shaped support groove 211 will change, resulting in the size of the support part 210 along the length direction of the first connecting rod 101 changing. At this time, it is necessary to adjust the position of the support part 210 in the length direction of the first connecting rod 101 to avoid interference between two adjacent support parts 210, so the above structure is provided to improve the flexibility of the equipment.

[0046] Reference Figures 1 to 3 As shown, it can be understood that a group of positioning screws 240 are respectively provided on the opposite sides of the width direction of the first connecting rod 101, and a group of positioning screws 240 includes a plurality of positioning screws 240 arranged at intervals along the length direction of the first connecting rod 101, so that the support part 210 can be fixed more stably.

[0047] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
