Description

Technical Field

[0001] The present invention relates to the field of surveying and mapping technology, and particularly relates to a multi-form composite support device for surveying and mapping engineering. Background Technique

[0002] Surveying and mapping engineering mainly studies the basic knowledge and skills in aspects such as surveying and mapping science, precise spatial positioning and navigation, urban and engineering construction and their surveying projects, etc., and measures various information such as space, large-scale landforms, and geological structures and draws them into topographic maps.

[0003] Currently, a surveying instrument is needed for surveying during surveying and mapping. However, the current ground-touching structure of the surveying instrument is single, using a fixed anchor rod, such as the patent with the application number CN221858113U, which cannot be compatible with soft soil / hard rock composite terrain. In addition, the adjustment efficiency of the support legs is low, using traditional screw adjustment, such as the patent with the application number CN202223428942U, which requires manual adjustment step by step, taking 3 - 5 minutes. At the same time, it has the problem of insufficient slope adaptation. The maximum adaptable slope of the conventional support legs is only 25°. The rock slope is prone to slipping, and the surveying and mapping will be affected during vibration. Therefore, we propose a multi-form composite support device for surveying and mapping engineering to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a multi-form composite support device for surveying and mapping engineering.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] A multi-form composite support device for surveying and mapping engineering, including a bearing plate, a surveying and mapping device is provided at the upper end of the bearing plate. Four sliders are slidably connected to the lower end of the bearing plate. The sliders are connected by a locking mechanism. An automatic adjustment bracket is fixedly connected to the lower end of the slider. A buffer mechanism is connected to the lower end of the automatic adjustment bracket. A movable sleeve is connected to the lower end of the buffer mechanism. An electromagnetic adsorption mechanism is detachably connected to the lower end of the movable sleeve. A telescopic mechanism is provided in the middle of the lower end of the bearing plate. A strengthening mechanism is installed on the telescopic mechanism.

[0007] Optionally, the surveying and mapping device includes a rotating mechanism fixed to the upper end of the bearing plate. A surveying and mapping device body is installed at the upper end of the rotating mechanism. An operating mechanism and a receiving device are installed on the surveying and mapping device body.

[0008] Optionally, guide rails are fixedly provided on both sides of the lower end of the bearing plate. Two sliders on the same side are installed on one guide rail on the same side. The locking mechanism includes a screw rod penetrating through the slider. One end of the screw rod is connected with a rotating block. A plurality of threaded through holes are equidistantly provided on the guide rail. One end of the screw rod penetrates through one of the threaded through holes.

[0009] Optionally, the automatic adjustment bracket includes a first support column fixed to the lower end of the slider. A groove is provided at the lower end of the first support column. A connecting arm is rotatably connected in the groove. A fixing member is fixed to the lower end of the connecting arm. A second support column is rotatably connected to the fixing member.

A second hydraulic cylinder is rotatably connected to the lower end of the connecting arm. The end of the piston rod of the second hydraulic cylinder is rotatably connected to one side of the second support column.

[0010] Optionally, the buffer mechanism includes a mounting plate fixed to the lower end of the second support column. A magnetorheological damper is connected to the lower end of the mounting plate. A spring is sleeved on the magnetorheological damper. A movable sleeve is sleeved on the lower end of the second support column. The lower end of the magnetorheological damper is connected in the movable sleeve. A ground nail is screwed to the lower end of the movable sleeve.

[0011] Optionally, a threaded blind hole is provided at the lower end of the movable sleeve. A movable rod penetrates through the threaded blind hole. External threads are provided on the peripheral side wall of the upper end of the movable rod, and the external threads are screwed with the threaded blind hole. The electromagnetic adsorption mechanism includes a connecting plate fixed to the lower end of the movable rod. An electromagnetic chuck is fixed to the lower end of the connecting plate. A plurality of bionic claw nails are fixedly arranged at equal intervals at the lower end of the connecting plate.

[0012] Optionally, the telescopic mechanism includes a mounting tube fixed to the middle of the lower end of the bearing plate. A clamping groove is provided in the mounting tube. A servo motor is installed at the top in the mounting tube. The end of the output shaft of the servo motor is connected with a stud. A moving block is screwed to the lower end of the stud, and the moving block is clamped in the clamping groove. The strengthening mechanism includes an anchor rod fixed to the lower end of the moving block. A conical thorn is provided at the lower end of the anchor rod.

[0016] 2. By combining a magnetorheological damper with a spring for shock absorption, the suppression and adsorption of vibration are greatly enhanced, and the stability of support is improved.

[0017] 3. By switching between a double-mode of an anchor rod and an electromagnetic chuck, firm support can be provided for soft soil foundations and hard ground surfaces.

[0018] 4. Stable support for loose soft soil layers can be achieved through bionic claw nails.

[0019] 5. Stable support for terrains such as swamps can be achieved through the arrangement of insertion rods and ground nails.

[0020] In summary, the present invention can not only automatically adjust according to the terrain and angle, fully adapt to different terrains, but also provide stable support under different types of geological conditions, greatly enhancing the suppression and adsorption of vibration, improving the stability of support, and enhancing the stability and firmness of surveying and mapping.

Detailed implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Embodiment 1

[0034] Refer to Figure 1-8 , a multi - form composite support device for surveying and mapping engineering, including a bearing plate 1. A surveying and mapping device is provided at the upper end of the bearing plate 1. The surveying and mapping device includes a rotating mechanism 31 fixed to the upper end of the bearing plate 1. The upper end of the rotating mechanism 31 is installed with a mapping equipment body 29. An operating mechanism 32 and a receiving device 34 are installed on the mapping equipment body 29. The rotating mechanism 31 is fixed to the upper end of the bearing plate 1 and can drive the mapping equipment body 29 to rotate, thereby adjusting the direction and angle of surveying to meet the measurement requirements of different orientations. The operating mechanism 32 facilitates the operator to operate and set the mapping equipment body 29, and the receiving device 34 is used to receive various signals required during the surveying process, such as satellite signals, etc.;

[0035] Four sliders 20 are slidably connected to the lower end of the bearing plate 1. The sliders 20 are connected by a locking mechanism. Guide rails 22 are fixed to both sides of the lower end of the bearing plate 1. The guide rails 22 are fixed to both sides of the lower end of the bearing plate 1. Two sliders 20 on the same side are installed on one guide rail 22 on the same side, which can make the sliding of the sliders 20 more stable and smooth, and at the same time adjust the position of the automatic adjustment bracket at the lower end;

[0036] The locking mechanism includes a screw rod 24 penetrating through the slider 20. One end of the screw rod 24 is connected with a rotating block 21. A plurality of threaded through holes 23 are equidistantly arranged on the guide rail 22. One end of the screw rod 24 penetrates through one of the threaded through holes 23. When it is necessary to fix the slider 20, the operator rotates the rotating block 21 to make one end of the screw rod 24 penetrate through one of the threaded through holes 23 on the guide rail 22, thereby locking the slider 20 on the guide rail 22. It can also be existing stable connection methods such as clamping or buckling. A plurality of threaded through holes 23 are equidistantly arranged on the guide rail 22, and the slider 20 can be locked at different positions on the guide rail 22 to meet different surveying and mapping layout requirements;

[0037] A self - adjusting bracket is fixedly connected to the lower end of the slider 20. The self - adjusting bracket includes a first support column 2 fixed to the lower end of the slider 20. A groove 12 is provided at the lower end of the first support column 2. A connecting arm 3 is rotatably connected in the groove 12. A fixing member 13 is fixed to the lower end of the connecting arm 3. A second support column 4 is rotatably connected to the fixing member 13. A first hydraulic cylinder 5 is movably connected to one side of the first support column 2. The piston rod of the first hydraulic cylinder 5 is rotatably connected to one side of the connecting arm 3. A second hydraulic cylinder 6 is rotatably connected to the lower end of the connecting arm 3. The end of the piston rod of the second hydraulic cylinder 6 is rotatably connected to one side of the second support column 4. By controlling the telescoping of the first hydraulic cylinder 5 and the second hydraulic cylinder 6, the movement of the connecting arm 3 and the second support column 4 can be driven, thereby automatically adjusting the height and angle of the bracket to meet different terrain and measurement height requirements;

[0038] A buffer mechanism is connected to the lower end of the self - adjusting bracket. The buffer mechanism includes a mounting plate 26 fixed to the lower end of the second support column 4. A magnetorheological damper 27 is connected to the lower end of the mounting plate 26. A spring 28 is sleeved on the magnetorheological damper 27. A movable sleeve 7 is sleeved on the lower end of the second support column 4. The lower end of the magnetorheological damper 27 is connected in the movable sleeve 7. When the device is subjected to external vibration or impact, the spring 28 first plays a buffering role and absorbs part of the energy. At the same time, the magnetorheological damper 27 can adjust the damping force by changing the viscosity of the internal magnetorheological fluid according to the intensity and frequency of the vibration, further enhancing the buffering effect and protecting the surveying and mapping equipment from damage;

[0039] The lower end of the buffer mechanism is sleeved with a movable sleeve 7. The lower end of the movable sleeve 7 is detachably connected with an electromagnetic adsorption mechanism. The bottom of the movable sleeve 7 is provided with a threaded blind hole 16. A movable rod 8 is arranged through the threaded blind hole. An external thread 30 is arranged on the side wall of the upper end of the movable rod 8 for one week, and the external thread 30 is screwed with the threaded blind hole 16. The electromagnetic adsorption mechanism includes a connecting plate 33 fixed to the lower end of the movable rod 8. An electromagnetic chuck 9 is fixed to the lower end of the connecting plate 33. The electromagnetic adsorption mechanism includes the connecting plate 33 fixed to the lower end of the movable rod 8 and the electromagnetic chuck 9 fixed to the lower end of the connecting plate 33. In some occasions where stable fixation is required, such as on a metal floor, turning on the electromagnetic chuck 9 can firmly adsorb the device on the ground, improving the stability of the device;

[0040] In the middle of the lower end of the bearing plate 1, a telescopic mechanism is provided. The telescopic mechanism includes an installation pipe 10 fixedly connected to the lower end of the bearing plate 1. A clamping groove 25 is arranged in the installation pipe 10. A servo motor 17 is installed at the top in the installation pipe 10. The output shaft end of the servo motor 17 is connected with a stud 18. The lower end of the stud 18 is screwed with a moving block 19, and the moving block 19 is clamped in the clamping groove 25. The servo motor 17 drives the stud 18 to rotate. Since the moving block 19 is clamped in the clamping groove 25 and cannot rotate with the stud 18, the rotation of the stud 18 will cause the moving block 19 to move up and down along the stud 18, thus realizing the telescopic function of the telescopic mechanism and further adjusting the height of the device;

[0041] A strengthening mechanism is installed on the telescopic mechanism. The strengthening mechanism includes an anchor rod 11 fixed to the lower end of the moving block 19. A tapered thorn 35 is arranged at the lower end of the anchor rod 11. On some soft ground, the anchor rod 11 is inserted into the ground through the telescopic mechanism, and the tapered thorn 35 can more easily penetrate the ground, increasing the friction and stability between the device and the ground and preventing the device from displacing during the surveying process.

[0042] Embodiment 2

[0043] Refer to Figure 9 This Embodiment 2 is different from Embodiment 1 in that Embodiment 2 further includes that a ground nail 14 is screwed at the lower end of the movable sleeve 7. The ground nail 14 adopts an extended rod body and can provide stable support during surveying in swamps and fluids.

[0044] Embodiment 3

[0045] Refer to Figure 10The difference between the third embodiment and the first embodiment is that the third embodiment further includes: a plurality of bionic claws 15 are provided at the lower end of the connecting plate 33; the bionic claws imitate the gripping structure of natural organisms (such as animal claws or plant roots); the surface of the bionic claws is often designed to have multiple teeth or forked shapes, which can effectively embed into soft soil, gravel or uneven ground, thereby improving the adaptability of the device in complex terrain, especially in slopes, muddy or gravel environments, which can reduce the risk of sliding and ensure the stability of the surveying and mapping equipment; and can also perform multi-angle anchoring; a plurality of bionic claws are evenly spaced to form a multi-point support structure, disperse the weight of the equipment, and avoid collapse caused by excessive pressure at a single point; the surface of the bionic claws has grooves or elastic coatings, which can reduce soil adhesion and maintain long-term grip performance.

[0046] In the present invention, an anchor rod 11 is used in combination with an electromagnetic suction cup 9. A 20mm anchor rod is used for soft soil foundations, and the puncture depth is ≥300mm. Electromagnetic adsorption is started on hard surfaces with a suction force ≥200N. When in a loose soft soil layer, the bionic claw nail 15 can be replaced. 12 groups of tungsten steel nails are arranged at the end of the bionic claw nail array, with an expansion angle of 0-90°. The loose soil layer is penetrated by the hydraulic drive of the automatic adjustment bracket to achieve firm fixation. The hydraulic telescopic stroke of the automatic adjustment bracket is 0-800mm. Combined with a MEMS inclination sensor (accuracy 0.01°), the leg length is automatically adjusted to adapt to terrain with a slope of ≤40°. During vibration, the magnetorheological damper suppresses low-frequency shaking, and the spring 28 absorbs medium and high-frequency vibrations. The present invention can also adapt to the installation and bearing of various instruments, and has a wide range of applications. It can also be used in gas sampling, environmental monitoring sound wave testing, noise detection and other fields.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
