Description

Technical Field

[0001] The invention belongs to the technical field of fixed-point marking devices, and in particular relates to a fixed-point marking device and method for geological exploration. Background Art

[0002] Geological exploration is a survey and research activity that uses various means and methods to survey and detect geology, determine the appropriate bearing layer, determine the foundation type based on the bearing capacity of the bearing layer, and calculate the foundation parameters. It is to find industrially significant deposits in the mineral survey, to find out the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and to provide the mineral reserves and geological data required for mine construction design, and to investigate and study the geological conditions such as rocks, strata, structures, minerals, hydrology, and landforms in a certain area. In the process of exploration, individual geographical locations generally need to be marked at fixed points, and most of them are marked with positioning flags.

[0003] However, most existing methods of using positioning flags are to insert them directly into the ground. When the wind is strong outdoors, the positioning flag may be blown down by the strong wind, making the fixed point marking inaccurate. In addition, the soil in some places is hard and difficult to insert into the soil, or in some areas with low terrain, it will be difficult to observe the positioning flag after it is inserted.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0029] like Figures 1 to 4 As shown, a fixed-point marking device for geological exploration described in this embodiment includes a first base 1, a hole groove is opened at the center position of the top of the first base 1, and a positioning flag 2 is inserted in the hole groove, and two corresponding cavities are opened inside the first base 1. The left and right side walls of the first base 1 are movably penetrated with corresponding threaded rods 9, and one end of the threaded rod 9 extending into the cavity is fixedly installed with the inner wall of the first base 1 through a bearing, and the end of the threaded rod 9 away from the first base 1 passes through the first base 1 and is fixedly installed with a handle, and a bearing can be installed at the position in contact with the first base 1 to facilitate the rotation of the threaded rod 9. A moving block 10 is threadedly connected to the threaded rod 9, and a connecting member 11 is fixedly connected to the top of the moving block 10. A moving groove 12 is opened at the top of the first base 1 relative to the position of the threaded rod 9, and the moving groove 12 is consistent with the threaded rod 9. The moving groove 12 is in the shape of a long strip, and the connecting member 11 is located in the moving groove 12, and the connecting member 11 is limited and slidable in the moving groove 12. The top of the connecting member 11 is fixedly connected with an extrusion plate 13, and the two extrusion plates 13 are located on both sides of the positioning flag 2. Figure 1-2As shown. When inserting the positioning flag 2, the positioning flag 2 is inserted into the hole groove of the first base 1, and the handle is rotated to rotate the threaded rod 9, and the thread drives the moving block 10. Due to the limitation of the moving groove 12, the moving block 10 slides in the moving groove 12, and then drives the extrusion plate 13 to move. The extrusion plates 13 on both sides of the positioning flag 2 are close to the middle to clamp and fix the positioning flag 2. The positioning flags 2 on both sides can be provided with arc grooves, which are more secure for clamping the round rod of the positioning flag 2. Preferably, a rubber layer is provided on the outer periphery of the extrusion plate 13 to increase the friction on the positioning flag 2 and facilitate fixation. In order to ensure the locking of the rotational position of the threaded rod 9, a self-locking screw can be used, or a locking mechanism can be provided. The locking of the screw is a prior art and will not be described here.

[0030] The bottom of the first base 1 is fixedly connected to a corresponding electric telescopic rod 3, and the bottom of the electric telescopic rod 3 is fixedly connected to a second base 4. The electric telescopic rod 3 is provided with a plurality of electric telescopic rods 3 to play a role of uniform support. In this example, there are four electric telescopic rods 3, see the attached Figure 4 The electric telescopic rod 3 between the first base 1 and the second base 4 can be conveniently adjusted in height, thereby realizing convenient up and down adjustment of the height of the positioning flag 2, which can ensure that the staff of the fixed-point survey can see the positioning flag 2 located in the low-lying area, and effectively improve the applicability of the positioning flag 2 in various complex terrains.

[0031] A plurality of lifting legs 5 are installed on the side of the second base 4. The plurality of lifting legs 5 are evenly distributed around the circumference. In this example, there are four lifting legs 5. Figure 4 The lifting leg 5 includes a support leg 14, a sliding groove 15, an extrusion groove 16, a connecting rod 17, and a spring 18. Four connecting rods 17 connected to the lifting leg 5 are provided on the side of the second base 4. The bottom of the support leg 14 is conical, and a sliding groove 15 and an extrusion groove 16 are provided on the side of the support leg 14 close to the second base 4. Figure 3 As shown, the sliding groove 15 is a T-shaped groove. The left end of the connecting rod 17 passes through the extrusion groove 16, and the leftmost end of the connecting rod 17 is inserted into the sliding groove 15. The end of the connecting rod 17 inserted into the sliding groove 15 is provided with a raised plate, and the raised plate can slide up and down in the sliding groove 15. The spring 18 is installed in the extrusion groove 16. There are two springs 18. One end of the two springs 18 is fixedly connected to the connecting rod 17, and the other end is fixedly connected to the upper top wall and the lower bottom wall of the extrusion groove 16 respectively. When not subject to external force, the connecting rod 17 supporting the second base 4 is located in the middle position of the support leg 14, see the attached Figure 3 Hint.

[0032] A forward and reverse motor 6 is fixedly installed at the top center of the second base 4. The center of the second base 4 is vertically aligned with the center of the first base 1. A rotating shaft 7 is fixedly connected to the bottom of the forward and reverse motor 6, and the rotating shaft 7 movably penetrates the second base 4. A drilling rod 8 is fixedly connected to the bottom of the rotating shaft 7. The bottom of the drilling rod 8 is conical, and a spiral downward rotating blade 19 is arranged around the drilling rod 8. When there is no external force, the bottom end of the drilling rod 8 and the bottom end of the support leg 14 are in the same horizontal plane. The rotating blade 19 on the drilling rod 8 is spiral downward. Starting the forward and reverse motor 6 can facilitate drilling into the soil. After the drilling rod 8 is fully extended into the soil, the second base 4 is attached to the ground, and the four lifting legs 5 will be moved downward, so that the conical head of the lifting leg 5 is deeply buried in the soil, forming a deep burial of the middle drilling rod 8 and shallow penetration of the four conical heads around the soil, forming a five-point support for the second base 4, enhancing the grip and improving the stability of the device in fixed point fixation. When taking out the device, the forward and reverse motor 6 rotates in the reverse direction, the drilling rod 8 is gradually pushed out of the soil, the connecting rod 17 moves upward, and after the drilling rod 8 exits the soil, the conical head of the lifting leg 5 is manually pulled out, and the removal is completed. The spring 18 provided here is to make the bottom end of the supporting leg 14 of the device and the bottom end of the drilling rod 8 be in the same horizontal plane when there is no external force and the motor is not working. When placed normally, it is conducive to the stable placement of the device. In addition, when the elastic force is controlled within a certain range, the upward and downward pulling and pressing of the spring can guide the sliding of the connecting rod 17 in the sliding groove 15, which is conducive to smooth and stable sliding.

[0033] Marking method:

[0034] Step 1, select a marking location, place the device at the selected point, and align the cone tip of the drilling rod 8 with the marking point;

[0035] Step 2, start the forward and reverse motor 6, extend the drilling rod 8 into the soil, wait for the second base 4 to fit on the ground, and stop the forward and reverse motor 6;

[0036] Step 3, insert the positioning flag 2 into the hole groove of the first base 1, rotate the handles on both sides, and the threaded rod 9 rotates to move the moving block 10, so that the extrusion plates 13 on both sides clamp the positioning flag 2 firmly;

[0037] Step 4: According to the height difference of the marking point, the electric telescopic rod 3 is activated to adjust the distance between the first base 1 and the second base 4 to adjust the height of the positioning flag 2, and the positioning flag 2 is placed at a fixed point. According to the height difference of the marking point, the electric telescopic rod 3 between the first base 1 and the second base 4 can be easily adjusted in height to adjust the height of the first base 1, thereby realizing the height adjustment of the positioning flag 2.

[0038] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
