[0002] In order to exploit mineral resources, it is necessary to conduct geological exploration of the target area before mining. Geological exploration refers to the investigation and research of geological conditions such as rocks, stratigraphic structures, minerals, groundwater, and landforms in a certain area through various means and methods. Based on the investigation, analysis and comprehensive evaluation of various geological data on geological resources, corresponding plans and long-term forecasts are made to provide exploration basis for the exploitation of mineral resources and engineering construction.

[0003] Geological exploration methods mainly include ground observation, geological mapping, drilling, ultrasonic testing, geological radar detection and other auxiliary means. Drilling is a common exploration sampling method, which is mainly suitable for identifying the properties of weathering crust and bedrock, and can be used to explore and identify the characteristics of bedrock, faults, weak interlayers and intrusive rocks. It is also the main method of geological exploration for ground iron ore, non-ferrous metals and radioactive elements. However, the hardness and inclination of the stratum, changes in the physical and mechanical properties of the rock, and rock structures such as cleavage, foliation, and bedding can easily lead to borehole deviation, which will not only reduce the drilling efficiency, but also easily affect the accuracy of geological exploration.

[0004] To this end, those skilled in the art have proposed a broken stratum drilling equipment for anti-drift geological drilling and a drift warning system to solve the problems raised by the background technology. Summary of the invention

DETAILED DESCRIPTION

[0035] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] Embodiment 1

[0037] As attached Figure 1 To Attachment Figure 3As shown, the present invention provides a broken formation drilling device for anti-drift geological drilling, including an adjustment component 100, including a base plate 101, wherein the base plate 101 can provide support and space for the installation of other parts, a moving component 102 connected to the lower surface of the base plate 101, wherein the moving component 102 allows the device to move, a positioning component 103 connected to the upper surface of the base plate 101, wherein the positioning component 103 allows the device to stably stop at a specified position, a lifting component 104 arranged on the upper surface of the base plate 101, wherein the lifting component 104 is used to control the drilling depth of the drilling component 105, and a drilling component 105 connected to the lifting component 104, wherein the drilling component 105 is used for drilling exploration;

[0038] The anti-deviation component 200 includes a motion component 201 fixedly connected to the upper surface of the base plate 101, wherein the motion component 201 will rotate around the drilling component 105 with the monitoring component 202 and the correction component 203, a monitoring component 202 arranged on the motion component 201, wherein the detection component is used to monitor whether the drilling component 105 is deviated, a correction component 203 arranged on the motion component 201, wherein the correction component 203 is used to correct a slight deviation of the drilling component 105, and a warning component 204 arranged on the upper surface of the base plate 101, wherein the warning component 204 will issue a warning when the drilling component 105 is deviated, thereby serving as a reminder;

[0039] The motion assembly 201 includes a gear ring 201a fixedly connected to the upper surface of the base plate 101, an annular track 201b fixedly connected to the upper surface of the gear ring 201a, a sliding frame 201c slidably connected to the annular track 201b, wherein the sliding frame 201c slides along the annular track 201b and then drives the mounting plate 201d to rotate around the drilling assembly 105, a mounting plate 201d fixedly connected to the upper surface of the sliding frame 201c, a motion motor 201e fixedly installed on the upper surface of the mounting plate 201d, wherein the motion motor 201e drives the motion gear 201g to rotate through the motion rod 201f, a motion rod 201f fixedly connected to the output end of the motion motor 201e, and a motion gear 201g fixedly connected to the motion rod 201f, and since the motion gear 201g is meshed with the gear ring 201a, when the motion gear 201g rotates, it pushes the sliding frame 201c to slide along the annular track 201b.

[0040] Specifically, the motion component 201 is provided with two groups, the monitoring component 202 and the correction component 203 are respectively installed on one motion component 201, the lower end of the motion rod 201f passes through the mounting plate 201d, and the motion gear 201g is meshed with the gear ring 201a.

[0041] As can be seen from the above, the device is moved to the drilling site by the moving component 102, and the positioning component 103 is used to limit the device to a specified position to prevent the drilling component 105 from shaking or the working surface from being uneven when working. When the drilling component 105 is drilling, the drilling depth is controlled by the lifting component 104. During the drilling process, the motion motor 201e rotates with the motion gear 201g through the motion rod 201f. Since the motion gear 201g is meshed with the gear ring 201a, when the motion gear 201g rotates, it will push the sliding frame 201c along the The monitoring component 202 and the correction component 203 slide along the annular track 201b and rotate around the drilling component 105. The monitoring component 202 moves in a circle along the sliding frame 201c to monitor the drilling component 105 in real time. When a deviation occurs, the warning component 204 issues an alarm to serve as a warning. At this time, the drilling work is stopped, and the correction component 203 is used to correct the slight deviation of the drilling component 105. If the deviation is large, the drilling component 105 is moved up by the lifting component 104 and the drilling is re-drilled.

[0042] Embodiment 2

[0043] As attached Figure 1 To Attachment Figure 3 As shown, this embodiment is basically the same as the previous embodiment, except that the correction component 203 includes a guide rail 203a fixedly mounted on the upper surface of the mounting plate 201d, a correction plate 203b slidably connected to the guide rail 203a, the movement of the synchronization plate 203e will bring the correction plate 203b to move along the guide rail 203a, and the correction hole 203c that penetrates the correction plate 203b, wherein the correction hole 203c can limit the maximum deviation angle of the drilling component 105, and the correction plate 203b will push or pull the drilling component 105 when moving with the correction hole 203c, thereby correcting the slight deviation of the drilling component 105, the correction electric cylinder 203d fixedly mounted on the upper surface of the mounting plate 201d, and the synchronization plate 203e fixedly connected to the correction plate 203b and the correction electric cylinder 203d respectively, wherein the correction electric cylinder 203d will drive the synchronization plate 203e to move.

[0044] Specifically, the monitoring component 202 is an infrared ranging sensor 202a, which monitors the distance with the drilling component 105 through the infrared ranging sensor 202a, and sends a signal to the PLC controller when the distance exceeds the set value; the warning component 204 includes a control box 204a, in which a PLC controller is installed, and the operation of the remaining electronic parts is controlled by programming of the PLC controller, as well as an audible and visual alarm 204b fixedly installed on the upper surface of the control box 204a. The PLC controller processes the data of the infrared ranging sensor 202a, and controls the audible and visual alarm 204b to issue a warning when the distance exceeds the set value.

[0045] As can be seen from the above, the infrared ranging sensor 202a is used to monitor the distance from the drilling component 105. When the distance exceeds the set value, a signal will be sent to the PLC controller. At this time, the PLC controller controls the sound and light alarm 204b to issue a warning based on the data of the infrared ranging sensor 202a, and then notifies the staff. The positive electric cylinder drives the synchronous plate 203e to move, and then moves the correction plate 203b along the guide rail 203a. The correction plate 203b moves synchronously with the correction hole 203c. The correction hole 203c will push or pull the drilling component 105, thereby correcting the slight offset of the drilling component 105.

[0046] Embodiment 3

[0047] As attached Figure 4 To Attachment Figure 6 As shown, this embodiment is basically the same as the previous embodiment, except that the moving component 102 includes a support column 102a fixedly connected to the lower surface of the base plate 101, and the base plate 101 is erected at a certain height through the support column 102a, thereby improving the passability of the device on uneven roads, and a roller 102b fixedly connected to the lower surface of the support column 102a, and the device can be moved through the roller 102b.

[0048] Specifically, the positioning assembly 103 includes a positioning plate 103a fixedly connected to the upper surface of the base plate 101, wherein the positioning plate 103a is an "L"-shaped plate, the positioning plate 103a provides storage space for the hydraulic cylinder 103b, the hydraulic cylinder 103b fixedly connected to the positioning plate 103a, and a contact plate 103c fixedly connected to the hydraulic cylinder 103b, the hydraulic cylinder 103b drives the contact plate 103c to move downward, so that the contact plate 103c contacts the ground, thereby fixing the position of the device, and at the same time, through the cooperation of multiple positioning assemblies 103, a certain degree of horizontal adjustment can be performed.

[0049] Furthermore, the lifting assembly 104 includes a mounting frame 104a fixedly mounted on the upper surface of the base plate 101, a lifting motor 104b fixedly mounted in the mounting frame 104a, wherein the lifting motor 104b drives the threaded rod 104c to rotate when working, the threaded rod 104c fixedly connected to the output end of the lifting motor 104b, and a guide rod 104d fixedly connected to the mounting frame 104a, wherein the guide rod 104d is used to assist the lifting plate 104e to move up and down stably, and the lifting plate 104e threadedly connected to the threaded rod 104c, The lifting plate 104e is affected by the thread and will move up and down along the guide rod 104d according to the rotation direction of the threaded rod 104c, and the support plate 104f is fixedly connected to the lifting plate 104e, wherein the support plate 104f and the lifting plate 104e are lifted and lowered synchronously, and the support frame 104g is fixedly connected to the upper and lower surfaces of the support plate 104f. Since the drilling assembly 105 is installed on the lower surface of the support plate 104f, the support capacity can be improved from the side through the support frame 104g to prevent the support plate 104f from bending and being damaged due to long-term use.

[0050] Furthermore, the threaded rod 104c is rotatably connected to the mounting frame 104a, the guide rod 104d is slidably connected to the lifting plate 104e, and the support frame 104g is in contact with the mounting frame 104a.

[0051] Furthermore, the drilling assembly 105 includes a drilling motor 105a fixedly mounted on the lower surface of the support plate 104f, wherein the operation of the drilling motor 105a drives the drill rod 105b to rotate for drilling, the drill rod 105b is fixedly connected to the output end of the drilling motor 105a, and a through groove 105c passing through the base plate 101. When the drill rod 105b is working, it passes through the base plate 101 through the through groove 105c and drills into the ground. The drill rod 105b, the through groove 105c and the correction hole 203c are located on the same axis.

[0052] As can be seen from the above, the device is moved to the drilling site by the roller 102b, and then the hydraulic cylinder 103b is started, and the hydraulic cylinder 103b drives the contact plate 103c to move downward, so that the contact plate 103c contacts the ground. Multiple groups of hydraulic cylinders 103b and contact plates 103c cooperate to fix the position of the device and complete the horizontal adjustment to avoid deviation of the drilling angle. The drilling motor 105a rotates with the drill rod 105b to perform drilling work. At the same time, the lifting motor 104b drives the threaded rod 104c to rotate, and the lifting plate 104e is affected by the thread and moves downward along the guide rod 104d, thereby causing the support plate 104f to move downward with the drilling assembly 105 to control the drilling depth. During the process, the motion component 201 rotates around the drill rod 105b with the infrared ranging sensor 202a and the correction plate 203b. The correction hole 203c on the correction plate 203b can limit the maximum deviation angle of the drill rod 105b. The infrared ranging sensor 202a monitors the distance between the drill rod 105b and sends a signal to the PLC controller when the distance exceeds the set value. At this time, the PLC controller controls the sound and light alarm 204b to issue a warning based on the data sent by the infrared ranging sensor 202a, and then notifies the staff. If the deviation is small, the correction component 203 is used to correct it. If the deviation is large, the drilling component 105 is moved up through the lifting component 104 and the drilling is re-drilled.
