[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0041] like Figure 1 As shown, it is a schematic diagram of the structure of a hole-opening orienting instrument for a mining intrinsically safe drilling rig according to a preferred embodiment of the present invention. The hole-opening orienting instrument for a mining intrinsically safe drilling rig in this embodiment comprises a supporting base plate 200, a hole-opening orienting instrument 100 is placed on the upper end of the supporting base plate 200, a supporting vertical rod 209 is detachably connected to the bottom of the supporting base plate 200, and three supporting legs 300 are installed on the outer wall of the supporting vertical rod 209. In this embodiment, the level of the supporting base plate 200 is adjusted by the supporting legs 300, and the hole-opening of the drilling rig can be positioned by the hole-opening orienting instrument 100.

[0042] like Figure 2 As shown, it is a schematic diagram of the structure of the hole orientation instrument in this embodiment. The hole orientation instrument 100 has a built-in three-axis gyroscope. A lifting handle 102 is installed on the upper end of the hole orientation instrument 100. A liquid crystal display screen 101 is provided on the outer wall of the hole orientation instrument 100. A CAN bus interface 103, a 485 wiring port 104 and a USB wiring port 105 are provided on one side of the hole orientation instrument 100. The hole orientation instrument 100 has a built-in Bluetooth module. In this embodiment, the orientation data can be displayed through the liquid crystal display screen 101, and the lifting handle 102 can be conveniently carried and taken. The lifting handle 102 is connected to an external device through the CAN bus interface 103, the 485 wiring port 104 and the USB wiring port 105. The three-axis fiber optic gyroscope requires horizontality and stillness when seeking north. When detecting excessive inclination or vibration during seeking north, the device will automatically stop seeking north and prompt the user to seek north again. After waiting for 10 seconds without manual operation, the device will autonomously seek north again. If the autonomous north seeking fails for multiple consecutive times, the device stops autonomous north seeking and waits for manual intervention.

[0043] like Figure 3 As shown, it is a schematic diagram of the support base plate structure in this embodiment, a plurality of threaded connecting rods 203 are fixedly connected to the bottom of the support base plate 200, and a threaded sleeve 202 is threadedly connected to the outer wall of each threaded connecting rod 203, and the bottoms of the plurality of threaded sleeves 202 are rotatably connected to the connecting base plate 201. In this embodiment, the threaded connecting rod 203 can be moved upward by rotating each threaded sleeve 202, so that the support base plate 200 can be moved upward, so that the horizontal height of the hole orientation instrument 100 can be adjusted, and can be adjusted according to actual usage conditions.

[0044] like Figure 3 as well as Figure 4As shown, it is a schematic diagram of the support base plate structure and a schematic diagram of the bottom structure of the support base plate in this embodiment, each threaded sleeve 202 passes through the connecting base plate 201, and the protruding end of each threaded sleeve 202 is detachably connected with a linkage sprocket 204, and the outer walls of multiple linkage sprockets 204 are sleeved with a driving chain 205. In this embodiment, by connecting multiple linkage sprockets 204 with the driving chain 205, when one side of the threaded sleeve 202 is rotated, the linkage sprocket 204 at the bottom rotates, and the driving chain 205 drives other linkage sprockets 204 to rotate, so that each threaded sleeve 202 can rotate at the same time, which makes the adjustment more convenient.

[0045] It is worth noting that the above-mentioned linkage sprocket 204 and drive chain 205 are linkage components in this embodiment, and the linkage components include but are not limited to the linkage sprocket 204 and drive chain 205. As long as it is a component that can make each threaded sleeve 202 rotate simultaneously, it can be applied to this embodiment.

A tension spring 206 is provided inside the first sliding groove 208, and the tension spring 206 pushes the first sliding block so that the tension sprocket 207 pushes the driving chain 205. The elastic force of the tension spring 206 can keep the driving chain 205 in a tense state at all times, thereby preventing the driving chain 205 from loosening and causing a failure to transmit.

[0047] It is worth noting that the above-mentioned tension spring 206, tension sprocket 207, first sliding block and first sliding groove 208 are the tensioning components in this embodiment. The tensioning components include but are not limited to the tension spring 206, tension sprocket 207, first sliding block and first sliding groove 208. As long as the components can keep the drive chain 205 in a tense state, they can be applied to this embodiment.

Figure 6In the structural schematic diagram of middle A and the structural schematic diagram of the reinforcing rib, the bottom of the supporting vertical rod 209 is detachably connected with a bottom connecting block 301, one end of each supporting leg 300 is fixedly connected with a rotating shaft 302, each rotating shaft 302 is rotatably connected to the bottom connecting block 301, and a parallel portion 303 is provided at the end of each supporting leg 300 away from the rotating shaft 302, and a bottom supporting ring 304 is provided at the bottom of the plurality of parallel portions 303, and a plurality of second sliding grooves 309 are provided at the upper end of the bottom supporting ring 304, and a second sliding block 310 is slidably connected inside each second sliding groove 309, and a rotating ball 311 is rotatably connected to the upper end of each second sliding block 310, and a second electric telescopic rod 308 is detachably connected to the upper end of each parallel portion 303, and the telescopic end of each second electric telescopic rod 308 passes through the parallel portion 303 and is fixedly connected to the outer wall of the rotating ball 311. In this embodiment, each rotating ball 311 is adaptively rotated when the second electric telescopic rod 308 is extended, so that the level can be automatically adjusted without manual adjustment in sequence.

[0049] It is worth noting that the above-mentioned second electric telescopic rod 308, rotating ball 311 and second sliding block 310 are the horizontal adjustment components in this embodiment. The horizontal adjustment components include but are not limited to the second electric telescopic rod 308, rotating ball 311 and second sliding block 310. As long as the components can adjust the level of the support base plate 200, they can be applied to this embodiment.

[0050] like Figure 5 as well as Figure 7 As shown, in order to be able to more conveniently adjust the height of the hole orienting instrument 100, in this embodiment, the bottom of the bottom connecting block 301 is detachably connected to the first electric telescopic rod 305, and the telescopic end of the first electric telescopic rod 305 is detachably connected to the support block 306, and the outer wall of the support block 306 is fixedly connected to a plurality of reinforcing ribs 307, each reinforcing rib 307 is fixedly connected to the upper end of the support leg 300. In this embodiment, by extending the first electric telescopic rod 305, each support leg 300 is rotated, and cooperates with the sliding of the second sliding block 310 in the second sliding groove 309, so that the height of the support base plate 200 can be adjusted, and the height of the support base plate 200 can be adjusted more conveniently. The bottom support ring 304 can increase the contact area with the ground, so that the equipment can be made more stable, and the reinforcing ribs 307 can further increase the stability of the equipment.

[0051] In summary, the specific use of this embodiment is as follows:

[0052] First, place the device in a suitable position. When the second electric telescopic rod 308 in the horizontal adjustment component is extended, each rotating ball 311 rotates adaptively, and each support leg 300 rotates adaptively through the rotating shaft 302, so that the level of the device can be automatically adjusted, making the horizontal adjustment more convenient. When adjusting the height of the support base plate 200, the first electric telescopic rod 305 is extended to make each support leg 300 rotate, and cooperate with the second sliding block 310 to slide in the second sliding groove 309, so that the height of the support base plate 200 can be adjusted, and the height of the support base plate 200 can be adjusted more conveniently. The bottom support ring 304 can increase the contact area with the ground, so that the device can be more stable. The reinforcement rib 307 can further increase the stability of the device. By rotating each threaded sleeve 202, the threaded connecting rod 203 can be moved upward, so that the support base plate 200 can be moved upward, so that the horizontal height of the hole orientation instrument 100 can be adjusted, and it can be adjusted according to actual usage conditions. Through the multiple linkage sprockets 204 in the linkage assembly and the drive chain 20 5 can rotate the threaded sleeve 202 on one side, and the linkage sprocket 204 at the bottom rotates, and the driving chain 205 drives the other linkage sprockets 204 to rotate, so that each threaded sleeve 202 can rotate at the same time, so that the adjustment can be more convenient, and the tension spring 206 in the tensioning assembly pushes the first slider so that the tension sprocket 207 pushes the driving chain 205, and the elastic force of the tension spring 206 can keep the driving chain 205 in a tense state at all times, so as to avoid the driving chain 205 from loosening and causing the transmission to fail. The orientation data can be displayed on the LCD screen 101, and the carrying handle 102 can be used for easy carrying. The carrying handle 102 is connected to external devices through the CAN bus interface 103, the 485 connection port 104 and the USB connection port 105. The three-axis fiber optic gyroscope requires horizontality and stillness when seeking north. When detecting excessive inclination or vibration during north seeking, the device will automatically stop seeking north and prompt the user to seek north again. After waiting for 10 seconds without manual operation, the device will autonomously seek north again. If the autonomous north seeking fails for multiple consecutive times, the device will stop autonomous north seeking and wait for manual intervention.
