Description

Technical Field

[0001] This invention relates to the field of rapid leveling technology, and more particularly to a rapid leveling device for use in outdoor fields. Background Technology

[0002] As a key component of range control and measurement equipment, the photoelectric theodolite possesses the important function of measuring the trajectory parameters of aerial targets, and is renowned for its ease of operation, operational stability, and excellent measurement accuracy. Measurement accuracy is one of the core indicators for evaluating the performance of a photoelectric theodolite. To ensure the acquisition of high-precision measurement data, it is crucial to precisely level the photoelectric theodolite to the horizontal plane before conducting the mission.

[0003] Currently, the leveling operation of photoelectric theodolites mainly relies on multiple leveling devices configured at their bottom. The leveling mechanism inside these devices uses a pair of wedge-shaped mechanical parts; however, the leveling process still requires manual observation and operation, which is not only inefficient but also prone to introducing large adjustment errors, making it difficult to meet the stringent high-precision requirements of photoelectric theodolites. Summary of the Invention

[0004] In view of this, the present invention aims to provide a rapid leveling device for field applications, which realizes automatic adjustment of the adjustment platform through a height adjustment mechanism and a height detection sensor.

[0005] To achieve the above objectives, the technical solution of this invention is implemented as follows: A rapid leveling device for field applications includes: an adjustment platform, a mounting base, and at least three springs, at least three height adjustment mechanisms, and at least three height detection sensors evenly arranged between the adjustment platform and the mounting base; the three springs and the three height adjustment mechanisms are spaced apart, and the height detection sensors are located between the springs and the height adjustment mechanisms; each height adjustment mechanism includes a drive component, a leveling roller assembly, and a wedge-shaped raceway; the wedge-shaped raceway is connected to the drive component, and the leveling roller assembly cooperates with the wedge-shaped raceway; when any height detection sensor detects that the height value at its location is less than or higher than a preset threshold, the drive component corresponding to the height detection sensor drives the wedge-shaped raceway to move, thereby driving the leveling roller assembly to move up and down, thereby adjusting the height of the adjustment platform in the area near the height detection sensor.

[0006] Furthermore, the drive assembly includes a power source and a screw, with the screw connected to the output end of the power source.

[0007] Furthermore, the power source is an electric motor or motor.

[0008] Furthermore, the height adjustment mechanism also includes a fixed frame, the upper surface of which is connected to the lower surface of the adjustment platform, and the other end of which is connected to the mounting base; the drive assembly is connected to the fixed frame along the circumferential direction of the mounting base, and the leveling roller assembly is connected to the lower surface of the fixed frame.

[0009] Furthermore, the leveling roller assembly includes a connecting lug, a connecting shaft, and rollers; the connecting lug is connected to the lower surface of the fixing frame, the connecting shaft passes through the connecting lug, and the rollers are rotatably disposed at both ends of the connecting shaft.

[0010] Furthermore, the outer contour of the connecting ear is U-shaped, and a through hole is provided on the U-shaped arc surface of the connecting ear, which is adapted to the connecting shaft.

[0011] Furthermore, the platform is adjusted to a first circular platform, and a first through hole is provided at the center of the platform.

[0012] Furthermore, the mounting base includes a second circular platform, an adapter, at least three adjustable legs, and at least three casters. The three adjustable legs and three casters are evenly arranged on the lower surface of the second circular platform through the adapter, and the three adjustable legs and three casters are spaced apart. The positions of the three adjustable legs correspond one-to-one with the positions of the three height adjustment mechanisms.

[0013] Furthermore, the adapter includes at least three connecting posts and at least three mounting blocks, which are evenly arranged on the lower surface of the second circular platform; the positions of the three connecting posts correspond one-to-one with the positions of the three height adjustment mechanisms.

[0014] Furthermore, one end of each of the three connecting columns is connected to the second circular platform, and the other end of each of the three connecting columns is connected to the three adjusting legs; one end of each of the three mounting blocks is connected to the second circular platform, and the other end of each of the three mounting blocks is connected to the three casters.

[0015] Compared with the prior art, the present invention can achieve the following beneficial effects: 1. By incorporating springs, when the quick leveling device moves or encounters vibration, the springs not only act as shock absorbers, effectively absorbing and dispersing impact forces, but also compensate for the height of the adjustment platform, ensuring that the adjustment platform remains at a stable and suitable working height.

[0016] 2. The height adjustment mechanism and height detection sensor are used to automatically adjust the platform, ensuring the accuracy of the adjustment. The structure is simple and easy to adjust.

[0017] 3. By installing casters, the position of the quick leveling device can be moved quickly. Attached Figure Description

[0024] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown in the figure, an embodiment of the present invention provides a rapid leveling device for use in an outdoor field, comprising: an adjustment platform 1, a mounting base 2, and at least three springs 3, at least three height adjustment mechanisms 4, and at least three height detection sensors 5, evenly disposed between the adjustment platform 1 and the mounting base 2. The three springs 3 and the three height adjustment mechanisms 4 are spaced apart, and the height detection sensors 5 are located between the springs 3 and the height adjustment mechanisms 4.

[0026] Adjustment platform 1 is a first circular platform, and adjustment platform 1 has a first through hole at its center.

[0027] like Figures 2-4 As shown, the mounting base 2 includes a second circular platform 21, an adapter 22, at least three adjustable legs 23, and at least three casters 24. The three adjustable legs 23 and three casters 24 are evenly distributed on the lower surface of the second circular platform 21 via the adapter 22, and are spaced apart. The positions of the three adjustable legs 23 correspond one-to-one with the positions of the three height adjustment mechanisms 4.

[0028] The second circular platform 21 has a second through hole 213 at its center. The diameter of the second circular platform 21 is equal to the diameter of the first circular platform 1. The diameter of the second through hole 213 is equal to the diameter of the first through hole.

[0029] A first positioning groove 211 and a second positioning groove 212 are also provided on the upper surface of the second circular platform 21. The first positioning groove 211 is a circular groove used to position the spring 3. One end of the spring 3 is embedded in the first positioning groove 211, and the other end of the spring 3 abuts against the lower surface of the adjusting platform 1. When the quick leveling device moves or encounters vibration, the spring 3 not only plays a role in shock absorption, effectively absorbing and dispersing the impact force, but also compensates for the height of the adjusting platform 1, ensuring that the adjusting platform 1 maintains a stable working height. The second positioning groove 212 is a rectangular groove used to position the height adjustment mechanism 4. By setting the first positioning groove 211 and the second positioning groove 212, the accuracy of the position of the spring 3 and the height adjustment mechanism 4 is ensured.

[0030] The adapter 22 includes at least three connecting posts 221 and at least three mounting blocks 222. The three connecting posts 221 and the three mounting blocks 222 are evenly arranged on the lower surface of the second circular platform 21. The positions of the three connecting posts 221 correspond one-to-one with the positions of the three height adjustment mechanisms 4.

[0031] One end of each of the three connecting columns 221 is connected to the second circular platform 21, and the other end of each of the three connecting columns 221 is connected to the three adjusting legs 23. One end of each of the three mounting blocks 222 is connected to the second circular platform 21, and the other end of each of the three mounting blocks 222 is connected to the three casters 24.

[0032] In this embodiment, adjacent connecting columns 221 and mounting blocks 222 are connected by connecting plates 223. Two stiffening plates 224 are also evenly arranged on the outer circumference of the connecting columns 221.

[0033] like Figure 5 , Figure 6 As shown, each height adjustment mechanism 4 includes a drive assembly 41, a leveling roller assembly 42, and a wedge-shaped raceway 43. The wedge-shaped raceway 43 is connected to the drive assembly 41, and the leveling roller assembly 42 cooperates with the wedge-shaped raceway 43. The drive assembly 41 includes a power source 411 and a screw 412, with the screw 412 connected to the output end of the power source 411. The power source 411 is a motor.

[0034] The height adjustment mechanism 4 also includes a fixed frame 44, the upper surface of which is connected to the lower surface of the adjustment platform 1, and the lower surface of the fixed frame 44 is connected to the mounting base 2. A drive assembly 41 is arranged radially along the mounting base 2 and connected to the fixed frame 44, and a leveling roller assembly 42 is connected to the lower surface of the fixed frame 44. The fixed frame 44 includes a movable top plate, the upper surface of which is connected to the lower surface of the adjustment platform 1.

[0035] The leveling roller assembly 42 includes a connecting ear 421, a connecting shaft 422, and a roller 423. The connecting ear 421 is connected to the lower surface of the top plate of the fixed frame 44, the connecting shaft 422 passes through the connecting ear 421, and the roller 423 is rotatably disposed at both ends of the connecting shaft 422.

[0036] The outer contour of the connecting ear 421 is U-shaped, and a through hole is provided at the lower end of the connecting ear 421, which is adapted to the connecting shaft 422.

[0037] On the inclined surface of the wedge-shaped raceway 43, two slides 431 are spaced apart, and rollers 423 are embedded in the slides 431 to cooperate with them. On the wedge-shaped raceway 43, along the moving direction of the wedge-shaped raceway 43, there is a threaded hole 432 adapted to the screw 412. One end of the screw 412 is connected to the output end of the power source 411, and the other end of the screw 412 passes through the threaded hole 432 and is connected to the fixed frame 44. When the power source 411 drives the screw 412 to rotate, it drives the wedge-shaped raceway 43 to move. By changing the position of the leveling roller assembly 42 on the inclined surface of the wedge-shaped raceway 43, the height of the top plate of the fixed frame 44 is adjusted, thereby achieving the leveling of the adjustment platform 1.

[0038] The height detection sensor 5 is an ultrasonic sensor or a laser rangefinder.

[0039] In this embodiment, the adjustment platform 1 is first coarsely adjusted using the adjustment leg 23, and then finely adjusted using the height adjustment mechanism 4.

[0040] When any height detection sensor 5 detects that the height value of its location is less than or higher than a preset distance, the drive component 41 corresponding to the height detection sensor 5 drives the wedge-shaped roller 43 to move, thereby driving the leveling roller assembly 42 to move up and down, thereby adjusting the height of the platform 1 in the area near the height detection sensor 5.

[0041] The preset distance is the distance between the lower surface of the adjustment platform 1 and the upper surface of the second circular platform 21.

[0042] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
