Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically a drilling device for mining geological surveying. Background Technology

[0002] Mine geological surveying refers to the mapping work carried out during the construction and mining process for mine planning and design, exploration and construction, production and operation management, and mine decommissioning. Any negligence or carelessness in mine surveying can affect production or may lead to serious accidents. Therefore, mine surveying plays a significant role in mine mining. Thus, the detection of soil moisture content is extremely important, as soil moisture content is related to the stability of mine geology. Therefore, drilling equipment is needed to sample the mine geology.

[0003] Currently, existing drilling equipment typically only drills holes in the geology and then extracts the soil from the drill pipe for moisture measurement. However, due to the complex geology in mines, the soil naturally contains some hard rocks. Therefore, during the drilling process, the drill pipe may come into contact with the hard rocks, generating a reverse force. This causes the drilling equipment to vibrate as a whole during drilling, making it difficult to complete the drilling and sampling work in a short time. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling device for geological surveying in mines, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A drilling device for geological surveying in a mine includes a fixed plate. A propulsion mechanism is provided on the top surface of the fixed plate. A drilling mechanism for sampling geological boreholes in the mine is provided at the bottom end of the propulsion mechanism and on the bottom surface of the fixed plate. Anchor rods are fixedly connected to the four corners of the bottom surface of the fixed plate. The length of the anchor rods is greater than the overall length of the drilling mechanism. A locking mechanism is slidably connected through the outer wall of the anchor rods. A moving wheel is fixedly connected to one end of the locking mechanism.

[0007] Furthermore, two symmetrical steel ropes are fixedly connected to each of the four edges of the bottom surface of the fixing plate, and an anchor is fixedly connected to one end of each steel rope.

[0008] Furthermore, the outer wall of the anchor rod has two symmetrical grooves, and the locking mechanism includes an installation plate that slides through the anchor rod at the corresponding position and is fixedly connected to the moving wheel at the corresponding position. One end of the top surface of the installation plate is fixedly connected to a fixing ring that slides through the anchor rod at the corresponding position. The inner wall of the fixing ring has an annular groove, and two symmetrical locking blocks that engage with the grooves at the corresponding positions are provided in the annular groove.

[0009] Furthermore, the outer wall of the card block is fixedly connected to two symmetrical springs that are also fixedly connected to the inner wall of the annular groove, and the outer wall of the card block is fixedly connected to a pull rod that slides through the fixed ring at the corresponding position.

[0010] Furthermore, the thickness of the card block is greater than the depth of the annular groove.

[0011] Furthermore, the propulsion mechanism includes four rectangularly distributed threaded sleeves that rotate through the fixed plate, with a screw screw screwed through the inside of each threaded sleeve, and a connecting rod fixedly connected to the bottom end of the screw screw and fixedly connected to the drilling mechanism.

[0012] Furthermore, the top surface of the fixed plate is fixedly connected to a U-shaped frame, the outer wall of the threaded sleeve is fixedly connected to a double-groove synchronous pulley, two adjacent double-groove synchronous pulleys are connected by a synchronous belt, the top surface of the U-shaped frame is fixedly connected to a motor, the output end of the motor passes through the inner top surface of the U-shaped frame and is fixedly connected to a single-groove synchronous pulley, and the single-groove synchronous pulley is connected to one of the double-groove synchronous pulleys by a synchronous belt.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By inserting a sufficiently long anchor rod into the soil and then fixing the anchor rod with the pressure applied by the soil, the soil's tightening force on the anchor rod gradually weakens under the reverse force, thus greatly preventing the overall jumping of the device during drilling, and thus enabling drilling to be completed in a short time.

[0015] 2. By inserting eight anchors into the soil and fixing them with the pressure within the soil, the overall stability of the device can be further increased, preventing the device from jumping around in a short period of time during the drilling process.

[0016] 3. By disengaging the two locking blocks at the same moving wheel from the corresponding grooves, the moving wheel can move on the anchor rod. When the locking block engages with the lower groove, the entire device can be moved by the moving wheel. When the locking block engages with the upper groove, the anchor rod can be inserted into the soil with sufficient length, thus making the device more stable. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this embodiment of the utility model, a drilling device for geological surveying in a mine includes a fixed plate 1. A propulsion mechanism 2 is provided on the top surface of the fixed plate 1. A drilling mechanism 3 for sampling geological boreholes in a mine is provided at the bottom end of the propulsion mechanism 2 and located on the bottom surface of the fixed plate 1. Anchor rods 11 are fixedly connected at the four corners of the bottom surface of the fixed plate 1. The length of the anchor rods 11 is greater than the overall length of the drilling mechanism 3. A locking mechanism 4 is slidably connected through the outer wall of the anchor rods 11. A movable wheel 5 is fixedly connected to one end of the locking mechanism 4.

[0024] Specifically, first, the device is moved to the area to be drilled. Then, the locking mechanism 4 is disengaged from the corresponding anchor rod 11. At this time, the locking mechanism 4 can drive the corresponding moving wheel 5 to slide on the outside of the corresponding anchor rod 11. The locking mechanism 4 and the corresponding moving wheel 5 are moved upward to a sufficient distance. Then, the locking mechanism 4 is locked to the corresponding anchor rod 11. At this time, the moving wheel 5 is disengaged from the ground and at a sufficient distance, while the anchor rod 11 is in contact with the ground. The other three anchor rods 11 are brought into contact with the ground in the same way. Then, the four anchor rods 11 are inserted into the soil. The pressure inside the soil can fix the anchor rods 11. Then, by utilizing... The drilling mechanism 3 is moved towards the ground by the propulsion mechanism 2, so that the drilling mechanism 3 can drill holes and sample the soil. If the drill pipe of the drilling mechanism 3 comes into contact with hard rocks in the soil during the drilling process, it will generate a reverse force and act on the fixing plate 1. The fixing plate 1 is tightly fixed in the soil by four anchor rods 11. Although the reverse force will also loosen the anchor rods 11 in the soil, the anchor rods 11 will not be completely loosened immediately after being subjected to the reverse force. Instead, the soil's fastening force on the anchor rods 11 will gradually weaken. Therefore, the overall jumping of the device can still be greatly avoided during the drilling process, so the drilling work can be completed in a short time.

[0025] Example 1

[0026] like Figure 2 As shown, in this embodiment, two symmetrical steel ropes 13 are fixedly connected to each of the four edges of the bottom surface of the fixing plate 1, and an anchor nail 14 is fixedly connected to one end of each steel rope 13.

[0027] In this embodiment, by inserting eight anchors 14 into the soil and fixing the anchors 14 with the pressure in the soil, the overall stability of the device can be increased again, preventing the device from jumping in a short period of time during the drilling process.

[0028] Example 2

[0029] like Figure 4 As shown, in this embodiment, the outer wall of the anchor rod 11 has two symmetrical grooves 12. The locking mechanism 4 includes a mounting plate 41 that slides through the anchor rod 11 at the corresponding position and is fixedly connected to the moving wheel 5 at the corresponding position. One end of the top surface of the mounting plate 41 is fixedly connected to a fixing ring 42 that slides through the anchor rod 11 at the corresponding position. The inner wall of the fixing ring 42 has an annular groove. Two symmetrical locking blocks 43 that lock into the grooves 12 at the corresponding positions are provided in the annular groove. Two symmetrical springs 44 that are fixedly connected to the outer wall of the locking blocks 43 are fixedly connected to the inner wall of the annular groove. A pull rod 45 that slides through the fixing ring 42 at the corresponding position is fixedly connected to the outer wall of the locking blocks 43. The thickness of the locking blocks 43 is greater than the depth of the annular groove.

[0030] In this embodiment, by pulling the two levers 45 at the same fixed ring 42, the four springs 44 at the corresponding positions can be compressed, causing the two locking blocks 43 to retract into the annular grooves at the corresponding positions. At this time, the restriction of the moving wheel 5 can be released, allowing the moving wheel 5 to slide on the outer wall of the anchor rod 11 at the corresponding position until the fixed ring 42 moves to the groove 12 at the top of the anchor rod 11 at the corresponding position. At this time, the two levers 45 can be released, and the two locking blocks 43 will be locked into the groove 12 at the corresponding position under the elastic action of the two springs 44 at the corresponding positions. At this time, the moving wheel 5 is fixed to the top of the anchor rod 11 at the corresponding position, so that the anchor rod 11 has sufficient length to be inserted into the soil, thus making the device more stable.

[0031] Example 3

[0032] like Figure 3 As shown, in this embodiment, the propulsion mechanism 2 includes four rectangularly distributed threaded sleeves 21 that rotate through the fixed plate 1. A screw 22 is screwed through the inside of each threaded sleeve 21. The bottom end of the screw 22 is fixedly connected to a connecting rod 23 that is fixedly connected to the drilling mechanism 3. A U-shaped frame 15 is fixedly connected to the top surface of the fixed plate 1. A double-groove synchronous pulley 24 is fixedly connected to the outer wall of the threaded sleeve 21. Two adjacent double-groove synchronous pulleys 24 are connected by a synchronous belt. A motor 25 is fixedly connected to the top surface of the U-shaped frame 15. The output end of the motor 25 passes through the inner top surface of the U-shaped frame 15 and is fixedly connected to a single-groove synchronous pulley. The single-groove synchronous pulley is connected to one of the double-groove synchronous pulleys 24 by a synchronous belt.

[0033] In this embodiment, the four threaded sleeves 21 can be rotated simultaneously by the drive of the motor 25. The four rotating threaded sleeves 21 can move the four screws 22 simultaneously, thereby moving the drilling mechanism 3. Therefore, pressure can be applied to the drilling mechanism 3, enabling the drilling mechanism 3 to drill and sample.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
