For example, some measuring devices can only rotate at a limited angle in the horizontal direction and are difficult to accurately measure targets in the vertical direction or at an inclined angle; although some measuring devices have a certain angle adjustment function, the adjustment process is cumbersome and requires manual repeated operation and calibration, which not only consumes a lot of time and energy but also easily leads to inaccurate measurement results due to operation errors.

[0026] The following further describes in detail the embodiments of the present invention with reference to the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0027] Example 1: As shown in the attached Figure 1 to the attached Figure 6 shown: The present invention provides a multi-directional measuring device for engineering surveying, including a bracket assembly, a support assembly, and a total station 26;

[0028] The bracket assembly includes a fixed disk 1, a hinge seat 2 fixed to the periphery of the fixed disk 1, a support rod 3 rotatably connected to the hinge seat 2, a telescopic sleeve 6 telescopically installed in the fixed disk 1, and a telescopic rod 7 sliding in the telescopic sleeve 6. A first fastening knob 10 is installed on the top side of the telescopic sleeve 6. One end of the first fastening knob 10 abuts against the outer wall of the telescopic rod 7. By rotating the first fastening knob 10, the fastening knob is separated from the telescopic rod 7 to achieve the height adjustment of the telescopic rod 7;

[0029] The support assembly includes a support frame 11 fixed to one end of the telescopic rod 7, a connecting seat 12 installed on the upper part of the support frame 11, and a horizontal component installed between the support frame 11 and the connecting seat 12. The horizontal component controls the connecting seat 12 to maintain a horizontal state;

[0030] A rotating seat 19 is rotatably installed on the upper surface of the connecting seat 12. A top frame 24 is installed on the upper surface of the rotating seat 19. A rotating table 25 is rotatably installed on the inner wall of the top frame 24. A total station 26 is installed on the upper surface of the rotating table 25. A driving component is installed on the inner wall of the top frame 24. The driving component drives the rotating table 25 to rotate, and the rotation angle is from -90° to 90°.

[0031] The driving component includes a driving box 27 fixed to the upper surface of the rotating seat 19, a gear disk 28 fixed to the bottom surface of the rotating table 25, a screw rod 29 rotatably installed in the driving box 27, a sliding seat 30 threadedly engaged with the circumferential side of the screw rod 29, and a rack 31 fixed to the upper surface of the sliding seat 30. The rack 31 meshes with the gear disk 28; the screw rod 29 extends to the outer wall of the driving box 27, and one end of the screw rod 29 is fixedly connected with a second knob 32; by turning the second knob 32, the screw rod 29 is driven to rotate. During the displacement of the screw rod 29 driving the sliding seat 30, the rack 31 is driven to follow the displacement. The rack 31 cooperates with the gear disk 28 to enable the rotating table 25 to rotate along the top frame 24, realizing the angle adjustment of the rotating table 25.

[0032] A rotating shaft 20 is installed on the bottom surface of the rotating seat 19. The rotating shaft 20 is rotatably connected with the connecting seat 12. A worm gear 21 is installed on the circumferential side of the rotating shaft 20. A worm 22 is installed on the inner wall of the connecting seat 12. The worm 22 cooperates with the worm gear 21. One end of the worm 22 is installed with a first knob 23; by turning the first knob 23, the worm 22 is driven to rotate. The worm 22 cooperates with the worm gear 21 to enable the rotating shaft 20 to rotate, thereby realizing the angle adjustment of the rotating seat 19.

[0033] A connecting ball 4 is fixedly connected to the bottom of the support rod 3. A base 5 is sleeved and installed at the connecting ball 4. Through the connecting ball 4 and the base 5, the support angle of the base 5 can be flexibly changed, facilitating the support on the pitted ground.

[0034] As can be seen from the above, the height adjustment is carried out first. Rotate the first fastening knob 10 to separate it from the outer wall of the telescopic rod 7. At this time, the fixing constraint on the telescopic rod 7 is released. After loosening the first fastening knob 10, the telescopic rod 7 can freely slide axially in the telescopic sleeve 6 under its own gravity and external operating force, thereby realizing the height adjustment; after adjusting to the required height, rotate the first fastening knob 10 in the reverse direction to make it abut against the outer wall of the telescopic rod 7, and fix the telescopic rod 7 by using the frictional force to complete the height adjustment.

[0035] If it is necessary to adjust the angle of the rotating table 25, turn the second knob 32; the second knob 32 is fixedly connected to the screw rod 29. When the screw rod 29 rotates, according to the principle of screw pair transmission, the rotational motion of the screw rod 29 is converted into the linear motion of the slide block 30, and the slide block 30 displaces along the axis direction of the screw rod 29 in the drive box 27. The rack 31 fixed on the slide block 30 moves accordingly. The rack 31 and the gear disk 28 form a rack and pinion transmission mechanism, and the linear motion of the rack 31 drives the gear disk 28 to rotate, thereby causing the rotating table 25 mounted on the gear disk 28 to rotate along the inner wall of the top frame 24, realizing the angle adjustment from -90° to 90°.

[0036] If it is necessary to adjust the angle of the rotating seat 19, turn the first knob 23. The first knob 23 drives the worm 22 to rotate. The worm 22 and the worm gear 21 form a worm and worm gear transmission mechanism. The rotational motion of the worm 22 is transmitted to the worm gear 21 through meshing, causing the rotating shaft 20 coaxially installed with the worm gear 21 to rotate, and then driving the rotating seat 19 to rotate around the rotating shaft 20.

[0037] In addition, when the device is placed on an uneven ground, the support rod 3, through the cooperation of the connecting ball 4 and the base 5, utilizes the freedom degree of the ball joint structure, enabling the base 5 to rotate around the connecting ball 4 in multiple directions, flexibly changing the support angle to adapt to the pitted ground and ensuring the stability of the device.

[0038] Through the worm and worm gear transmission and the screw-rack compound drive structure in the drive assembly, high-precision adjustment of the horizontal rotation and pitching angle of the total station 26 is achieved. The self-locking characteristics of the worm 21 and the worm 22 effectively prevent the angle deviation caused by vibration or external force during the measurement process, ensuring the measurement stability; realizing multi-dimensional and large-range angle adjustment, breaking through the limitation of traditional measuring devices that can only perform limited angle measurements. Whether it is the target measurement in the horizontal direction or the vertical direction, accurate positioning can be achieved, effectively avoiding the measurement blind area caused by inconvenient angle adjustment, greatly improving the comprehensiveness and accuracy of the measurement, especially suitable for multi-directional measurement operations of complex building structures or terrains, and significantly enhancing the overall efficiency and quality of engineering measurement.

[0039] Embodiment 2: As shown in the appendix Figure 6As shown: This embodiment is basically the same as the previous embodiment, except that the horizontal assembly includes a connecting rod 13 fixed to the bottom surface of the connecting seat 12, a through groove 14 opened on the top surface of the support frame 11, a spherical groove 15 opened on the inner wall of the through groove 14, a limiting ball 16 fixed to the bottom surface of the connecting rod 13, and a counterweight ball 17 fixed to the bottom of the limiting ball 16. The connecting seat 12 and the counterweight ball 17 are vertically arranged; the limiting ball 16 is rotatably installed in the spherical groove 15, and the counterweight ball 17 is located in the support frame 11; the circumferential side of the spherical groove 15 is threaded with a second tightening knob 18; by loosening the second By tightening the knob 18, the restriction on the limit ball 16 can be released; when the measuring position at the top of the device is not in a horizontal state, the connecting seat 12 is tilted with the horizontal plane. At this time, the counterweight ball 17 is affected by gravity and falls to the lowest point. At this time, the counterweight ball 17 is perpendicular to the horizontal plane, and drives the limit ball 16 and the connecting rod 13, so that the connecting seat 12 is parallel to the horizontal plane, ensuring that the measuring device is in a horizontal state; at this time, by tightening the second tightening knob 18, the position of the limit ball 16 is locked, thereby locking the position of the connecting seat 12 to prevent the device from tilting due to shaking.

[0040] As can be seen from the above, before use, first loosen the second tightening knob 18. The second tightening knob 18 cooperates with the circumference of the spherical groove 15 through a thread. After loosening, the radial constraint on the limit ball 16 is released. When the measuring position at the top of the device is not in a horizontal state, the connecting seat 12 is inclined with the horizontal plane. At this time, the connecting rod 13 on the bottom of the connecting seat 12 drives the limit ball 16 and the counterweight ball 17 to deviate from the vertical direction. According to the principle of gravity, the counterweight ball 17 is affected by gravity and will fall to the position where the gravitational potential energy is the smallest, that is, the direction perpendicular to the horizontal plane. During the falling process of the counterweight ball 17, it drives the limit ball 16 to rotate in the spherical groove 15. The limit ball 16 pulls the connecting seat 12 through the connecting rod 13, so that the connecting seat 12 is gradually adjusted to a state parallel to the horizontal plane, thereby ensuring that the rotating seat 19 and the total station 26 installed on the connecting seat 12 are in a horizontal measurement state. When the connecting seat 12 is adjusted to be horizontal, tighten the second tightening knob 18. The second tightening knob 18 squeezes the inner wall of the spherical groove 15 and forms radial pressure on the limiting ball 16 through friction, thereby locking the position of the limiting ball 16 and fixing the position of the connecting seat 12 to prevent the device from tilting due to shaking during the measurement process, thereby ensuring the measurement accuracy.

[0041] By cleverly combining the effect of gravity with the ball joint structure, the problem of traditional measuring devices being prone to tilt on uneven ground and affecting measuring accuracy is fundamentally solved; the counterweight ball 17 automatically droops to a vertical direction under the action of gravity, driving the connecting seat 12 to adjust to a horizontal state. There is no need for repeated manual calibration and the assistance of a complicated level, which simplifies the level adjustment process and greatly reduces operation time and labor costs.

[0042] Meanwhile, the second fastening knob 18 locks the limit ball 16, effectively preventing the device from tilting due to external vibration or slight collision during the measurement process, ensuring that the measurement position is always in a horizontal and stable state, providing a high-precision measurement reference for surveying instruments such as total station 26, effectively reducing the measurement error caused by the tilting of the device. In complex terrains or construction sites with frequent vibrations, it can stably and accurately obtain measurement data, significantly improving the reliability and accuracy of engineering surveys.

[0043] Embodiment 3: As shown in the appendix Figure 1 : On the basis of Embodiment 1, a third fastening knob 33 is installed on the peripheral side of the fixed disk 1. The bottom of the telescopic sleeve 6 is fixedly connected to a connecting frame 8. A number of limiting rods 9 are fixedly connected to the peripheral side of the connecting frame 8. The limiting rods 9 are hingedly connected to the support rods 3; By providing the connecting frame 8 and the limiting rods 9, it is ensured that the three groups of support rods 3 are always at the same support angle, ensuring the support consistency of the support rods 3. The telescopic length of the telescopic sleeve 6 can be adjusted by the third fastening knob 33, driving the limiting rods 9 to move accordingly, thereby changing the support angle of the support rods 3 to ensure stable support; By adjusting the first fastening knob 10, the telescopic height of the telescopic rod 7 can be adjusted, thereby adjusting the position height of the total station 26.

[0044] As can be seen from the above, the principle of height adjustment is the same as that in Embodiment 1, that is, by rotating the first fastening knob 10 to control the sliding of the telescopic rod 7 in the telescopic sleeve 6, the adjustment of the position height of the total station 26 is realized. When adjusting the support angle of the support rod 3, rotate the third fastening knob 33. The third fastening knob 33 is in threaded cooperation with the fixed disk 1. When rotating, an axial force is generated to push or pull the telescopic sleeve 6 to expand or contract radially along the fixed disk 1. The connecting frame 8 at the bottom of the telescopic sleeve 6 is fixedly connected to the limiting rod 9. When the telescopic sleeve 6 expands or contracts, it drives the limiting rod 9 to move. The limiting rod 9 is hinged to the support rod 3. According to the lever principle and the motion characteristics of the linkage mechanism, the movement of the limiting rod 9 will change the included angle between the support rod 3 and the fixed disk 1, realizing the adjustment of the support angle of the support rod 3. Since the three groups of limiting rods 9 move synchronously, it is ensured that the three groups of support rods 3 are always at the same support angle, maintaining the support stability. When it is necessary to adjust the height of the total station 26, the first fastening knob 10 and the third fastening knob 33 can be adjusted simultaneously. The former controls the height of the telescopic rod 7, and the latter adjusts the overall support structure by changing the angle of the support rod 3 to accurately control the position height of the total station 26, enabling the measuring device to stably and flexibly complete the measurement task in complex terrain environments, meeting the requirements of engineering surveys for different heights and stable supports.

[0045] By adding a support angle adjustment structure, the organic unity of height adjustment and support stability is achieved, greatly enhancing the adaptability of the measuring device in complex environments. The linkage design of the third fastening knob 33 with the telescopic sleeve 6 and the limiting rod 9 can flexibly adjust the support angle of the support rod 3 according to different terrain conditions, enabling the three groups of support rods 3 to always maintain the same support angle and form a stable triangular support structure. Compared with traditional measuring devices with single height adjustment or fixed support angles, it can provide stronger support force and stability on complex terrains such as soft ground and slopes, effectively avoiding tilting or shaking of the device. When adjusting the height of the total station 26, the height adjustment and support angle adjustment work together, which can not only ensure that the measuring instrument is at an appropriate measuring height but also ensure the stability of the overall structure, enabling the measuring device to operate stably and reliably under various complex working conditions, effectively improving the efficiency and safety of engineering surveys, and meeting the stringent requirements of high precision and high stability for various engineering surveys.

[0046] The embodiments of the present invention are given for the purposes of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
