Description

Technical Field

[0001] The invention relates to the technical field of surveying and mapping supports, and in particular to a high-precision adaptive surveying and mapping instrument positioning support platform. Background Art

[0002] In construction projects, surveying and mapping is an important part of ensuring construction accuracy and project quality. With the increasing complexity and scale of construction projects, higher requirements are placed on the accuracy, stability and adaptability of surveying and mapping instruments. Although traditional triangulated surveying and mapping support brackets can meet basic measurement needs to a certain extent, there are still many problems in practical applications.

[0003] First, the adaptive capabilities of traditional triangulation support brackets are limited. When measuring on uneven or inclined ground, these brackets are difficult to quickly and accurately adjust to a horizontal state, which not only increases the difficulty of the operator's work, but may also cause deviations in the measurement data. Especially in situations where high-precision measurements are required, even a small angle error may lead to a large cumulative error, thus affecting the quality control of the entire project.

[0004] Secondly, the existing triangular surveying support brackets do not perform well in dealing with environmental vibrations. Construction sites are usually accompanied by various mechanical operations and human activities, which will produce varying degrees of vibration. The ordinary triangular support brackets lack effective shock absorption measures, making the precision surveying equipment installed on them susceptible to external interference, thus affecting the final data collection quality. This problem is particularly prominent when conducting long-term continuous measurements or measurement tasks that require high stability.

[0005] Furthermore, for occasions where frequent movement is required to complete comprehensive coverage measurement, the existing triangulation support brackets are bulky and inconvenient to disassemble and assemble, which greatly limits their flexibility and convenience. This is obviously a problem that needs to be solved urgently for modern construction projects that pursue efficient operation.

[0006] Finally, some existing triangulation support brackets are often relatively simple in design and cannot adapt well to the needs of different types of surveying instruments and their accessories. This not only limits their scope of application, but may also affect the overall efficiency of surveying work.

The bottom end of the stable telescopic rod 102 is provided with a stable gasket 103 to ensure the stability of the platform on various terrains. When the position needs to be fixed, the telescopic rod extends to contact the ground, and the friction is increased by the gasket to ensure that the device will not move due to external forces. The fixed bracket 200 provides a basic support frame and provides installation points for other components. The leveling mechanism 400 is composed of a leveling frame 410, a leveling base frame 420, an angle limit assembly 300 and an angle fixing assembly 430. Among them, the leveling frame 410 can rotate around an axis for the first level of rough horizontal adjustment. The angle limit assembly 300 allows the user or system to set and lock the angle of the leveling frame 410 to ensure that it is stable in a specific position. The leveling base frame 420 is installed in the leveling frame 410 and can rotate along another axis perpendicular to the former to provide a second level of finer angle adjustment. The angle fixing assembly 430 also uses a method similar to the angle limiting assembly 300 to fix the angle of the leveling base 420. The cooperation between the two is used to solve the measurement error problem caused by the uneven platform when the surveying and mapping instrument is operating on different inclined ground. The positioning frame 500 cooperates with the leveling base 420 to further fix the position of the surveying and mapping instrument through the angle locking assembly 580 to ensure its precise positioning on the platform, thereby providing a precise installation position for the surveying and mapping instrument and reducing the measurement error caused by the position offset of the instrument. The positioning support mechanism 600 is used to place and stabilize the surveying and mapping instrument to ensure that it will not be displaced after leveling, thereby achieving precise lifting and smooth rotation of the surveying and mapping instrument.

[0057] Further, the fixed bracket 200 includes a fixed frame 201 symmetrically arranged on the surveying and mapping base 100, the fixed frame 201 is provided with a rotating frame 202 that cooperates with the angle limiting assembly 300, and the rotating frame 202 is provided with a rotating bearing 203 that cooperates with the leveling frame 410; the leveling frame 410 is symmetrically provided with two rotating shafts 411 that cooperate with the rotating bearing 203, the angle limiting assembly 300 includes an angle sleeve 310 sleeved on the rotating shaft 411, the angle sleeve 310 is provided with a connecting ring plate 320 fixedly connected to the fixed frame 201, the connecting ring plate 320 is provided with a connecting screw 330 connected to the connecting ring plate 320, the angle sleeve 310 is provided with a fixing sleeve 340, and the fixing sleeve 340 is provided with a fixing screw 350 that cooperates with the rotating shaft 411;

[0059] Further explanation, the fixed bracket 200 is composed of a fixed frame 201 symmetrically arranged on the surveying and mapping base 100, which is the basic structure of the entire support platform. A rotating frame 202 is designed on the fixed frame 201, and the rotating bearing 203 cooperates with the rotating shaft 411 of the leveling frame 410 to realize the free rotation of the leveling frame 410 in a two-dimensional plane. This design facilitates the adjustment of the angle of the leveling frame 410 to adapt to different terrain conditions. Two rotating shafts 411 are symmetrically arranged on the leveling frame 410, which cooperate with the rotating bearing 203 to ensure the stability of rotation. The angle limit assembly 300 is composed of an angle sleeve 310 sleeved on the rotating shaft 411, a connecting ring plate 320, a connecting screw 330, a fixed sleeve 340 and a fixing screw 350. By adjusting the tightness of the connecting screw 330, the position of the angle sleeve 310 on the rotating shaft 411 can be controlled, thereby limiting the rotation range of the leveling frame 410 and achieving preliminary angle positioning. The structure of the angle fixing assembly 430 is consistent with that of the angle limiting assembly 300, and is used to fix the rotation angle of the leveling frame 410 after leveling is completed to ensure the stability of the platform.

[0062] The stabilizing component 450 includes two groups of stabilizing seats 451 symmetrically arranged on the surveying and mapping base 100, and one group of the stabilizing seats 451 includes a plurality of stabilizing seats 451 horizontally arranged on the surveying and mapping base 100; two groups of connecting seats 452 are symmetrically arranged on the leveling frame 410, and one group of the connecting seats 452 includes a connecting seat 452 horizontally arranged at the bottom end of the frame of the leveling frame 410; the stabilizing seats 451 correspond to the connecting seats 452 one by one, and a plurality of connecting members 453 are arranged between the stabilizing seats 451 and the connecting seats 452; the structure of the stabilizing component 460 is consistent with the structure of the stabilizing component 450.

[0063] Specifically, the connecting member 453 can be configured to connect a telescopic rod, and both ends of the connecting telescopic rod are provided with a rotating socket hingedly connected to the stabilizing seat 451 or the connecting seat 452, and the stabilizing seat 451 and the hinged seat are provided with a plug rod that cooperates with the rotating socket. At the same time, both ends of the connecting telescopic rod can also be provided with connecting hooks that are hung and connected to the stabilizing seat 451 or the connecting seat 452.

[0065] Specifically, the synchronous drive unit 444 includes a drive slot provided on the surveying and mapping base 100, a moving screw is provided in the drive slot, and two moving worms with opposite threads are provided on the moving screw, a drive seat that is slidably matched with the drive slot is provided in the drive slot, and the drive seat is fixedly connected to the clamping frame 441. At the same time, the synchronous drive unit 444 can also be configured as a drive gear and a drive rack that meshes with the drive gear and is fixedly connected to the clamping frame 441. In addition, the synchronous drive unit 444 can also be configured as two sets of drive hydraulic rods that are symmetrically arranged in the surveying and mapping base 100.

[0066] Further explanation, the preliminary clamping and fixing assembly 440 is composed of a clamping frame 441, a clamping plate 442, a storage slot 443 and a synchronous drive unit 444. The clamping frame 441 cooperates with the fixing frame 201, the clamping plate 442 contacts the leveling frame 410, and the clamping frame 441 is driven by the synchronous drive unit 444 to move in the same direction or in opposite directions to achieve preliminary clamping and fixing of the leveling frame 410. This design can respond quickly and preliminarily fix the rotation angle of the leveling frame 410, laying the foundation for subsequent precise adjustment. The stabilizing assembly 450 is composed of a stabilizing seat 451, a connecting seat 452 and a connecting member 453. The stabilizing seat 451 is symmetrically arranged on the surveying and mapping base 100, and corresponds to the connecting seat 452 on the leveling frame 410 one by one. The connecting member 453 can be connected to a telescopic rod or a telescopic rope. By adjusting the length of the connecting member 453, the rotation angle of the leveling frame 410 can be further fixed to improve the stability of the platform. Rotating sockets and plugs are arranged at both ends of the telescopic rod, as well as connecting hooks to ensure the firmness of the connection. The length of the connecting telescopic rope is adjusted through hooks and rope tighteners to achieve a flexible and stable connection.

[0067] The structure of the stabilizing component 460 is consistent with that of the stabilizing component 450, and is used to further fix the rotation angle of the leveling base 420. The leveling base 420 is firmly connected to the surveying and mapping base 100 through the connecting piece 453 to ensure the stability of the surveying and mapping instrument during operation.
