Description

Technical Field

[0001] This utility model relates to the field of mining technology, and in particular to a drilling trajectory measurement device for mining. Background Technology

[0002] Drilling is a crucial step in the entire mining process, and its accuracy and efficiency have a profound impact on subsequent ore mining operations. The drilling trajectory measurement device is a core piece of equipment for directional drilling in coal mines. By monitoring the drilling trajectory in real time, it ensures construction safety and efficiency. The drilling trajectory measurement device mainly consists of a non-magnetic drill rod, an inner core tube, and a mining-specific smartphone.

[0003] When using a mining drilling trajectory measurement device, the inner core tube needs to be placed inside a non-magnetic drill rod. However, in the current technology, when the inner core tube is placed inside the non-magnetic drill rod, it cannot be effectively fixed. During use, the inner core tube will constantly shake and be bumped inside the non-magnetic drill rod, which will cause damage to the inner core tube and affect the service life of the device. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: In the existing technology, when the inner core tube is placed in the non-magnetic drill rod, it cannot effectively fix the inner core tube. During use, the inner core tube will shake and be bumped continuously in the non-magnetic drill rod, which will cause damage to the inner core tube and affect the service life of the device. Therefore, a mining drilling trajectory measurement device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mining drilling trajectory measurement device includes a non-magnetic drill rod and an inner core tube. A positioning block is fixedly installed inside the non-magnetic drill rod. A connecting sleeve is threaded to the lower end of the non-magnetic drill rod. A mounting base is fixedly installed inside the connecting sleeve. The mounting base has a cavity inside. Multiple vertical tubes, each communicating with the cavity, are vertically and fixedly installed on the upper surface of the mounting base. A moving rod is vertically and slidably installed inside each of the multiple vertical tubes. An annular top block is fixedly installed at the upper end of each of the multiple moving rods. The inner core tube is clamped between the top block and the positioning block.

[0007] The connecting sleeve has an air injection hole on its side that communicates with the cavity, and a sealing component for sealing the air injection hole is installed inside the cavity.

[0008] Preferably, the sealing assembly includes a straight rod that is horizontally slidably installed in the air injection port via an elastic component and a sealing block that is fixedly sleeved on the straight rod, wherein the sealing block is in sealing contact with one end of the air injection port.

[0009] Preferably, the elastic component includes a support block fixedly installed in the cavity and a telescopic spring sleeved on a straight rod. The support block has a horizontally opening for a movable hole, and the straight rod is horizontally slidably inserted into the movable hole. The two ends of the telescopic spring are fixedly connected to the support block and the sealing block, respectively.

[0010] Preferably, a sealing plug is inserted into the air injection hole, and a groove is provided at one end of the sealing plug.

[0011] Preferably, a sealing gasket is fixedly installed at the lower end of the movable rod, and the side of the sealing gasket is in sealing contact with the side wall of the vertical pipe.

[0012] Preferably, protective pads are fixedly installed on both the top block and the positioning block, and the protective pads are made of rubber.

[0013] The beneficial effects of this utility model are as follows:

[0014] When the inner core tube is placed inside the non-magnetic drill rod, air is injected into the cavity through the air injection hole. Under the action of gas pressure, the moving rod can be pushed to move inside the vertical tube, thereby driving the top block to move towards the positioning block. Under the action of the sealing component, the inner core tube can be stably clamped and fixed between the positioning block and the top block, which can prevent the inner core tube from shaking inside the non-magnetic drill rod during the use of the device, avoid damage to the inner core tube, and avoid affecting the service life of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-6 A mining drilling trajectory measurement device includes a non-magnetic drill rod 1 and an inner core tube 2. A positioning block 3 is fixedly installed inside the non-magnetic drill rod 1. A connecting sleeve 4 is threaded to the lower end of the non-magnetic drill rod 1. A mounting base 5 is fixedly installed inside the connecting sleeve 4. A cavity 6 is opened inside the mounting base 5. Multiple vertical tubes 7, each connected to the cavity 6, are vertically fixedly installed on the upper surface of the mounting base 5. A moving rod 8 is vertically sealed and slidably installed inside each of the multiple vertical tubes 7. An annular top block 9 is fixedly installed at the upper end of the multiple moving rods 8. The inner core tube 2 is clamped between the top block 9 and the positioning block 3. The inner core tube 2 is connected to a mining smartphone via Bluetooth. During the drilling process, the drilling trajectory can be monitored in real time through the inner core tube 2. One end of the connecting sleeve 4 is threadedly connected to one end of the non-magnetic drill rod 1, and the other end is used to connect to other drill rods.

[0024] The connecting sleeve 4 has an air injection hole 10 on its side that communicates with the cavity 6, and a sealing component for sealing the air injection hole 10 is installed inside the cavity 6.

[0025] When installing the inner core tube 2, insert the inner core tube 2 into the non-magnetic drill rod 1, so that one end of the inner core tube 2 contacts the positioning block 3. Then, inject air into the air injection hole 10 through the air inflation device. The pressure inside the cavity 6 increases. When the pressure inside the cavity 6 increases, the moving rod 8 can be driven to move vertically upward in the vertical tube 7 under the pressure. Multiple moving rods 8 drive the top block 9 to contact the other end of the inner core tube 2, thereby stably clamping and fixing the inner core tube 2 between the positioning block 3 and the top block 9. This can prevent the inner core tube 2 from shaking inside the non-magnetic drill rod 1 during the use of the device, avoid damage to the inner core tube 2, and affect the service life of the device.

[0026] The sealing assembly includes a straight rod 11 horizontally slidably installed in the air injection port 10 via an elastic component and a sealing block 12 fixedly sleeved on the straight rod 11. The sealing block 12 is in sealing contact with one end of the air injection port 10. The elastic component includes a support block 13 fixedly installed in the cavity 6 and a telescopic spring 14 sleeved on the straight rod 11. A moving hole is horizontally opened on the support block 13, and the straight rod 11 is horizontally slidably inserted into the moving hole. The two ends of the telescopic spring 14 are fixedly connected to the support block 13 and the sealing block 12, respectively.

[0027] The sealing block 12 slides horizontally in the cavity 6 via the straight rod 11 and the support block 13. Under the action of the elastic force of the telescopic spring 14, the sealing block 12 tends to move towards the air injection hole 10. During the inflation process, the gas will push the sealing block 12 towards the support block 13, and the telescopic spring 14 will be compressed, thereby opening the air injection hole 10. After the inflation is completed, under the action of the elastic force of the telescopic spring 14, the sealing block 12 will move towards the air injection hole 10, blocking the air injection hole 10 again, preventing the air in the cavity 6 from overflowing from the air injection hole 10.

[0028] When it is necessary to lock the inner core tube 2, use a tool to push the straight rod 11 toward the sealing block 12, thereby opening the air injection hole 10 and allowing the air in the cavity 6 to be discharged.

[0029] A sealing plug 15 is inserted into the air injection hole 10. One end of the sealing plug 15 has a groove. During the drilling process, the sealing plug 15 blocks the air injection hole 10 to prevent soil from entering the air injection hole 10 and blocking it.

[0030] A sealing gasket 16 is fixedly installed at the lower end of the moving rod 8. The side of the sealing gasket 16 is in sealing contact with the side wall of the vertical pipe 7, and the sealing gasket 16 ensures the sealing between the moving rod 8 and the vertical pipe 7.

[0031] Protective pads are fixedly installed on both the top block 9 and the positioning block 3. The protective pads are made of rubber. When the top block 9 and the positioning block 3 come into contact with the inner core tube 2, the protective pads can protect the inner core tube 2 and prevent damage to the surface of the inner core tube 2.

[0032] In this invention, when installing the inner core tube 2, the inner core tube 2 is inserted into the non-magnetic drill rod 1, so that one end of the inner core tube 2 contacts the positioning block 3. Then, air is injected into the air injection hole 10 through the air inflation device, and the pressure inside the cavity 6 increases. When the pressure inside the cavity 6 increases, the moving rod 8 can be driven to move vertically upward in the vertical tube 7 under the pressure. Multiple moving rods 8 drive the top block 9 to contact the other end of the inner core tube 2, thereby stably clamping and fixing the inner core tube 2 between the positioning block 3 and the top block 9. This can prevent the inner core tube 2 from shaking inside the non-magnetic drill rod 1 during the use of the device, avoid damage to the inner core tube 2, and avoid affecting the service life of the device.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
