DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-10An embodiment of the present invention is as follows: a photogrammetric measuring device for geotechnical survey, comprising a tripod fixed pan-tilt 1, three groups of telescopic support legs 2 are rotatably installed on the lower side of the tripod fixed pan-tilt 1, a fixed foot 3 is fixedly installed on the lower end of the telescopic support leg 2, a cable counter 4 is installed on the tripod fixed pan-tilt 1, a first cable 5 is arranged on the cable counter 4, the first cable 5 is wound on the cable winding wheel, a mounting straight cylinder 6 is fixedly installed on one end of the first cable 5, four groups of stabilizing rollers 7 are movably installed on the mounting straight cylinder 6, a rotating hole probe 8 is fixedly installed on the lower end of the mounting straight cylinder 6, a first mounting block 9 is arranged on the lower side of the tripod fixed pan-tilt 1, three groups of expansion support boxes 10 are movably installed on the first mounting block 9, the position of the expansion support box 10 is adapted to the position of the telescopic support leg 2, a rubber cushion layer 11 is fixedly installed in the expansion support box 10, and the fixed foot 3 is inserted in the rubber cushion layer 11. First of all, the working principle of the main body of the equipment is briefly explained here. The working condition of the equipment is to survey the upper drill hole on the ground. The specific process is to place the tripod near the rotating hole. The tripod is the general term for the overall structure of the tripod fixed pan-tilt head 1, the telescopic support leg 2 and the fixed foot 3. Then the cable counter 4 is fixed to the tripod fixed pan-tilt head 1 by bolts, and then the cable on the cable reel is wound around the cable counter 4, the rotating hole probe 8 is suspended on the upper side of the rotating hole, and then the first cable 5 is lowered until the rotating hole probe 8 gradually enters the rotating hole. The main body of this equipment is the existing mature technology, so the detailed working principle of the equipment will not be elaborated here. The equipment has the following problems during use. First of all, due to structural reasons, the center position of the tripod fixed pan-tilt head 1 is actually not exactly on the upper side of the rotating hole center, so the center of gravity of the tripod is not centered during use, and the conventional tripod only relies on the fixed foot 3 has a stable contact with the ground, and the contact area is small. In addition, the actual use environment is relatively complex, and the possibility of using it in a construction environment is high. Therefore, there is a certain risk of tipping over during the use of the tripod. In addition, since the position of the rotating hole is offset from the center of gravity of the tripod, some calibration structures of the tripod are not easy to use, which will also make the process of aligning the rotating hole probe 8 with the rotating hole difficult to a certain extent in the actual execution process. Therefore, the equipment is provided with a first mounting block 9 and an expansion support box 10 to solve the problem of the instability of the tripod, and a calibration ring 22 is also provided to assist in solving the problem of the rotating hole probe 8 being difficult to align with the rotating hole. In addition, the equipment is equipped with an installation straight cylinder 6 on the upper side of the rotating hole probe 8, and you can choose to assemble a stabilizing roller 7 or a scratching block 44. The stabilizing roller 7 has the function of assisting the rotating hole probe 8 to rise quickly, and the scratching block 44 has the function of collecting soil. The specific working principle will be described in detail below.

[0028] Furthermore, the rubber cushion layer 11 is provided with an array of engaging grooves 12, the inclination angle of the engaging grooves 12 gradually increases from the inside to the outside, the inclination angle of the engaging grooves 12 is adapted to the opening angle of the telescopic support leg 2, the shape of the engaging grooves 12 is adapted to the shape of the fixed foot 3, the fixed foot 3 is inserted into the engaging grooves 12 and the engaging grooves 12 and the fixed foot 3 are tightly fitted. The first mounting block 9 and the expansion support box 10 exist to provide the tripod with a flat support surface, and this structure is to increase the stability of the tripod body when the fixed foot 3 is placed in the expansion support box 10. Figure 3 It can be seen that the upper side of the rubber cushion layer 11 is provided with a wavy-shaped snap-fit ​​groove 12, and the angle and size of the snap-fit ​​groove 12 are adapted to the fixed foot 3. Therefore, when the fixed foot 3 is inserted into the snap-fit ​​groove 12, the protrusions on both sides of the snap-fit ​​groove 12 will elastically squeeze the fixed foot 3, so that the fixed foot 3 can be stably inserted into the snap-fit ​​groove 12. Combined with the functions of the first mounting block 9 and the extended support box 10, a good supporting environment can be provided for the tripod. In addition, since the first mounting block 9 and the extended support box 10 are separated from the tripod, this structure is also universal for conventional tripods, which increases the adaptability of the equipment when used.

[0029] Furthermore, fixed side panels 13 are fixedly installed on both sides of the expansion support box 10, and fixed sockets 14 are opened at the ends of the fixed side panels 13. The front end array of the expansion support box 10 is provided with four groups of storage slots 15, and fixing nails 16 are inserted in the storage slots 15. The size of the fixing nails 16 is adapted to the size of the fixing sockets 14. A first holding groove 17 is opened at the front end of the expansion support box 10, and the fixing nails 16 are inserted in the first holding groove 17. Second holding grooves 18 are opened on both sides of the fixing sockets 14. This structure further fixes the expansion support box 10 by inserting the fixing nail 16 into the fixing socket 14. At the same time, the device is provided with a storage slot 15 to store the fixing nail 16. Since the size of the storage slot 15 is adapted to the size of the fixing nail 16, the fixing nail 16 can be stably inserted in the storage slot 15 by being squeezed against the inner wall of the storage slot 15. A first taking groove 17 and a second taking groove 18 are provided to facilitate the taking of the fixing nail 16 by tools such as a claw hammer. This stabilization method is simple and stable, and does not require the additional carrying of the fixing nail 16. The fixing nail 16 can also be used to fix the expansion support box 10 without carrying additional tools, thereby increasing the stability and convenience of the device when in use.

[0030] Furthermore, a connecting block 21 is fixedly installed on one side of the first mounting block 9, and a calibration ring 22 is fixedly installed on the connecting block 21. The center of the calibration ring 22 is opposite to the center of the rotary hole probe 8 in a drooping state. Three groups of hinge grooves 20 are opened on the first mounting block 9, and a hinge block 19 is fixedly installed on the rear end of the expansion support box 10. The hinge block 19 is rotatably installed in the hinge groove 20. This structure solves two problems, one is the alignment problem of the rotary hole probe 8, and the other is the storage problem of the expansion support box 10 and the first mounting block 9 itself. Due to the presence of the calibration ring 22, it is only necessary to align the calibration ring 22 with the rotary hole. Whether the calibration ring 22 is larger than the rotary hole or smaller than the drilled hole, it does not affect the actual use. After the calibration ring 22 is aligned, the rotary hole probe 8 only needs to be installed to be in the aligned state, without the need for an additional calibration process, which increases the convenience of using the equipment. The expansion support box 10 is rotatably installed on the first mounting block 9, so that the expansion support box 10 can be folded up like a tripod, and because the expansion support box 10 is wider than the telescopic support leg 2, the folded tripod can be inserted into the first mounting block 9 and the expansion support box 10 after folding. After insertion, the expansion support box 10 is fixed by a rope or a cable tie, so that the storage space utilization rate is higher, and the calibration ring 22 can also serve as a handle to make the stored equipment easy to move, which increases the convenience of using the equipment.

[0031] Further, three groups of connecting columns 24 are fixedly installed on the installation straight cylinder 6, a rotating motor 25 is fixedly installed on one side of the installation straight cylinder 6, a second gear 26 is fixedly installed on the lower end of the rotating motor 25, one end of the second gear 26 is meshed with the first gear 23, the first gear 23 is located at the center position of the upper end of the installation straight cylinder 6, the second gear 26 and the first gear 23 are both rotatably installed in the installation straight cylinder 6, a first screw 27 is fixedly installed at the center position of the lower end of the first gear 23, a second mounting block 28 is rotatably installed on the upper end of the first screw 27, the second mounting block 28 is fixedly installed on the installation straight cylinder 6, and the second mounting block 2 8 is hinged with four groups of first hinged rods 29, a first screw sleeve 30 is arranged on the lower side of the mounting straight cylinder 6, the first screw sleeve 30 is connected to the first screw rod 27 by threading, the lower end of the first screw rod 27 is rotatably mounted on the mounting straight cylinder 6, four groups of second hinged rods 31 are hinged on the first screw sleeve 30, the second hinged rod 31 is hinged on the inner side of the first hinged rod 29, a stabilizing roller 7 is installed at the lower end of the first hinged rod 29, the lower end of the first hinged rod 29 is externally connected to the second cable 36, the second cable 36 is inserted through the mounting straight cylinder 6 and the lower end is fixedly mounted at the fixed center position of the lower end of the mounting straight cylinder 6, and the second cable 36 is connected to the rotary hole probe 8. This structure allows the stabilizing roller 7 to expand outward, and after expanding, the stabilizing roller 7 can fit the inner wall of the rotating hole, so that the stabilizing roller 7 can stabilize the mounting straight cylinder 6. Since the rotating hole probe 8 is suspended on the lower side of the mounting straight cylinder 6, the rotating hole probe 8 is also relatively stable after the mounting straight cylinder 6 is stabilized. Therefore, in the process of winding up the first cable 5, the rotating hole probe 8 will not swing to a large extent, so that the first cable 5 can be quickly wound up, which increases the convenience and stability of the equipment when used.

[0032] Furthermore, a counterweight 35 is fixedly mounted on one side of the upper end of the installation straight cylinder 6, the weight of the left side of the installation straight cylinder 6 is consistent with the weight of the right side of the installation straight cylinder 6, and the diameter of the installation straight cylinder 6 is larger than the diameter of the hole-turning probe 8. In addition to stabilizing the hole-turning probe 8, the installation straight cylinder 6 can also prevent the hole-turning probe 8 from hitting the wall during the descent process by its own size, thereby increasing the stability of the equipment when in use. In addition, the counterweight 35 can balance the weight of the installation straight cylinder 6 itself, so that the installation straight cylinder 6 is balanced during the suspension process.

[0033] Furthermore, a limiting groove 38 is provided on the lower side of the first hinged rod 29, a first limiting block 37 is inserted in the limiting groove 38, two groups of second screw sleeves 39 are fixedly installed in the limiting groove 38, two groups of first limiting holes 40 are provided on the first limiting block 37, the second screw sleeve 39 is inserted in the first limiting hole 40, a screw 41 is threadedly installed in the second screw sleeve 39, an oblique fixing block 32 is fixedly installed on the lower end of the first limiting block 37, a first mounting ring 33 is fixedly installed on the lower end of the oblique fixing block 32, the stabilizing roller 7 is rotatably installed on the first mounting ring 33, and a damping rubber ring 34 is fixedly installed on the stabilizing roller 7. This structure allows the stabilizing roller 7 to be disassembled, so that the stabilizing roller 7 can be replaced if it is severely worn during long-term use. In addition, the angle of the inclined fixing block 32 itself allows the stabilizing roller 7 to better exert force when it fits against the inner wall of the rotating hole, thereby increasing the stability of the equipment during use and reducing the cost of using the equipment, and providing conditions for subsequently replacing the stabilizing roller 7 with a scratch block 44.

[0034] Furthermore, a second limit block 42 can be inserted into the limit groove 38, and a second limit hole 43 is provided on the second limit block 42. The shape and size of the second limit block 42 are compatible with the first limit block 37, and the size of the second limit hole 43 is compatible with the first limit hole 40. A scratch block 44 is fixedly installed on the lower side of the second limit block 42, and a collection box 45 is rotatably installed on the lower side of the scratch block 44. A rotating groove 47 is provided at one end of the scratch block 44, and a second mounting ring 48 is fixedly installed in the rotating groove 47. A rotating rod 46 is fixedly installed on one end of the collection box 45, and the rotating rod 46 is rotatably installed in the second mounting ring 48. A torsion spring 49 is provided in the second mounting ring 48, and one end of the torsion spring 49 is fixedly installed in the second mounting ring 48 and the other end is fixedly installed on the rotating rod 46. The end of the collection box 45 exceeds the end of the scratch block 44. This structure is a replacement structure for the stabilizing roller 7. The function of the stabilizing roller 7 is to allow the first cable 5 to be quickly reeled up, while the function of the scratch block 44 is to collect the soil in the rotary hole, so that soil at a certain depth can be collected for analysis, which increases the functionality of the equipment when in use and provides favorable conditions for subsequent soil layer analysis.

[0035] Furthermore, the end of the scraping block 44 is sharp, and the scraping block 44 can completely seal the collection box 45. This structure allows the scraping block 44 to shrink after the soil layer is collected, and the collection box 45 can fit with the scraping block 44 under the action of the torsion spring 49, so that the collection box 45 is sealed, so that the soil layer in the collection box 45 can be completely taken out, and it is difficult to leak and be contaminated.

[0036] Working principle: When in use, the expansion support box 10 is unfolded, and the hinge block 19 rotates in the hinge slot 20, so that the expansion support box 10 and the first mounting block 9 are placed flat on the ground. Figure 2 As shown, the first mounting block 9 is moved so that the calibration ring 22 is aligned with the rotating hole, and then the fixing nail 16 in the storage slot 15 is pulled out, and the fixing nail 16 is inserted into the fixing socket 14 so that the expansion support box 10 can be fixed on the ground, and then the telescopic support leg 2 is unfolded, and the fixing foot 3 is inserted into the engaging groove 12 for fixing, and then the cable counter 4 is fixed on the tripod fixed pan head 1, and the first cable 5 is wound around the cable counter 4. At this time, the position of the rotating hole probe 8 is opposite to the calibration ring 22, and then the rotating hole probe 8 is gradually lowered to shoot the rotating hole. When the rotating hole probe 8 needs to be put away, the rotating motor 25 is started, and the rotating motor 25 rotates to drive the second gear 26 to rotate. The rotation of the second gear 26 drives the first gear 23 to rotate through meshing, thereby causing the first screw 27 to rotate, and the rotation of the first screw 27 drives the first screw sleeve 30 to rise through the threaded action between the first screw sleeve 30. At this time, the second hinged rod 31 is gradually flattened, thereby driving the first hinged rod 29 to extend outward, so that the stabilizing roller 7 and the rotating hole are connected. The inner part of the rotating hole 8 is fitted, and the relative position between the installation straight tube 6 and the inner wall of the rotating hole is fixed. Then, the first cable 5 is quickly rolled up to drive the rotating hole probe 8 to rise quickly. When it is necessary to collect the soil layer, the screw 41 is unscrewed from the second screw sleeve 39, the first limit block 37 is removed, and the second limit block 42 is inserted into the second installation block 28 and fixed by the screw 41. In the process of making the rotating hole probe 8 rise, the rotating motor 25 is started to make the first hinged rod 29 extend outward. At this time, the collection box 45 is first connected with the inner wall of the rotating hole. The collecting box 45 is in contact with the inner wall of the rotating hole. Since the collecting box 45 can rotate, the collecting box 45 rotates until the scratch block 44 contacts the inner wall of the rotating hole. At this time, the equipment mounting straight cylinder 6 continues to rise, and the ends of the scratch block 44 and the collecting box 45 will scratch the inner wall of the rotating hole, thereby causing the soil layer to fall off, and part of the soil layer will enter the collecting box 45. Then the first hinged rod 29 is retracted, and the collecting box 45 is merged with the scratch block 44 under the action of the torsion spring 49, so that the soil layer in the collecting box 45 is preserved. The above is the entire working principle of the present invention.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
