Description

Technical Field

[0001] This utility model relates to the field of instrument support technology, specifically a support for surveying instruments. Background Technology

[0002] When using surveying instruments, it is essential to level the instruments using a support frame. This is a crucial prerequisite for ensuring the accuracy of measurement data. Whether it is a traditional optical instrument (level, theodolite) or a modern electronic device (total station, GNSS receiver), their measurement principles all rely on a "horizontal reference" or "vertical reference." If the instrument is not level, it will directly introduce systematic errors, leading to invalid measurement results.

[0003] Traditional surveying instruments use a support structure, which relies on manual leveling of the instrument during use. In addition, during outdoor surveying, the support is easily affected by the outdoor environment (such as wind and soil collapse), causing the instrument to tilt again after manual leveling, resulting in errors in data measurement. Traditional surveying instrument supports lack automatic leveling compensation adjustment function. Utility Model Content

[0004] The purpose of this utility model is to provide a support for surveying instruments, which automatically adjusts the mounting base to a horizontal position through a horizontal gimbal assembly, unaffected by the tilt of the support leg structure, ensuring that the surveying instrument is always in a horizontal state during use, thereby solving the problems mentioned in the background art.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figures 1-6 The bracket for a surveying instrument shown includes:

[0028] The support structure for surveying instruments;

[0029] The support body structure includes a support base structure 1 and three sets of support leg structures 2 hinged to the bottom of the support base structure 1;

[0030] The support structure 1 includes a fixed base 3, a horizontal gimbal assembly 4 is provided in the inner cavity of the fixed base 3, and a mounting base 5 connected to the surveying instrument is fixed on the top of the horizontal gimbal assembly 4. The support foot structure 2 includes a fixed outer shell 6, an extension rod 7 is slidably provided in the inner cavity of the fixed outer shell 6, the bottom of the extension rod 7 extends through to the outside of the fixed outer shell 6, and a limiting assembly 8 is provided on the outside of the fixed outer shell 6 to limit the extension rod 7.

[0031] A fixing cylinder 10 is fixed at the center of the bottom of the fixing base 3, and a support component 9 for supporting the support foot structure 2 is provided on the outside of the fixing cylinder 10.

[0032] By setting up the horizontal gimbal component 4, the mounting base 5 can be easily adjusted horizontally within a certain tilt angle range, keeping the surveying instrument mounted on the top of the mounting base 5 horizontal and preventing the support leg structure 2 from shaking due to external interference during use, which would cause the surveying instrument to tilt. With the joint cooperation of the limiting component 8 and the support component, the support leg structure 2 can be supported, unaffected by the terrain, and the stability of the bracket body structure can be maintained.

[0033] Among them, such as Figure 2-4 As shown:

[0034] The horizontal gimbal assembly 4 includes a fixed shaft 41 fixed at the center of the bottom of the inner cavity of the fixed base 3. Connecting cylinders 42 are rotatably arranged from the inside to the outside of the fixed shaft 41. A fixed frame 43 is fixed to the top of each connecting cylinder 42. A movable frame 44 is hinged to the outside of the fixed frame 43. The end of the movable frame 44 away from the fixed frame 43 is movably connected to the outside of the mounting base 5. A driven gear 45 is fixed to the lower end of the outer wall of each connecting cylinder 42. A drive motor 46 is fixed around the bottom of the inner cavity of the fixed base 3. The output shaft of the drive motor 46 is fixed with a drive... The driving gear 47 meshes with the driven gear 45. The fixed base 3 is equipped with a gyroscope and a control chip. The horizontal state of the fixed base 3 can be monitored in real time through the control chip and the gyroscope. Then, the drive motor 46 is controlled. The drive motor 46 drives the fixed frame 43 to rotate through the driving gear 47 and the driven gear 45. Then, the fixed frame 43 drives the movable frame 44 to rotate, and the angle of the mounting frame is adjusted. By using the cooperation of multiple sets of movable frames 44, the dynamic horizontal adjustment of the mounting base 5 can be achieved.

[0035] Furthermore, such as Figure 6 As shown:

[0036] The limiting component 8 includes a fixed support base 81 fixed to the outside of the fixed housing 6. A movable wrench 82 is hinged to the outside of the fixed support base 81. One end of the movable wrench 82 passes through the fixed housing 6 and contacts the outer wall of the extension rod 7. By deflecting the movable wrench 82 on the fixed support base 81, the one end of the movable wrench 82 abuts against the extension rod 7, and the extension rod 7 is limited by friction, thus maintaining the stability of the extension rod 7 and the fixed housing 6.

[0037] Preferred, such as Figure 5-6 As shown:

[0038] The support assembly 9 includes a double-ended threaded seat 91 sleeved on the outside of the fixed cylinder 10. A movable ring 92 is movably disposed at the center of the outer side of the double-ended threaded seat 91. Support rods 93 are hinged around the outer periphery of the movable ring 92. The end of the support rod 93 away from the movable ring 92 is hinged to the inner side of the fixed support base 81. Two sets of limiting threaded cylinders 94 are fixed on the fixed cylinder 10 and threadedly connected to the double-ended threaded seat 91. By moving the double-ended threaded seat 91 up and down on the outside of the fixed cylinder 10, it can support the fixed outer shell 6 in conjunction with the support rods 93, and adjust the included angle between the fixed outer shell 6 and the fixed cylinder 10. The setting of the limiting threaded cylinders 94 facilitates the limiting of the double-ended threaded seat 91, maintains the angle of the fixed outer shell 6, and prevents the tilt angle of the fixed outer shell 6 from changing.

[0039] It is worth noting that, such as Figure 1-2 and Figure 5 As shown:

[0040] The inner cavity of the fixed cylinder 10 is filled with a battery 11, and a control switch 12 is provided on the outside of the fixed base 3. The battery 11, control switch 12, control chip and drive motor 46 are electrically connected to each other. The horizontal gimbal assembly 4 is started by the control switch 12, and the battery 11 provides the power required for the operation of the horizontal gimbal assembly 4.

[0041] In a further preferred embodiment, such as Figure 5 As shown:

[0042] The bottom of the fixed cylinder 10 is provided with a charging port 13, which is electrically connected to the control chip. The bottom of the fixed cylinder 10 is covered with a protective cover 14. The battery 11 can be charged through the charging port 13, which is convenient for outdoor use of the device. At the same time, the protective cover 14 can protect the charging port 13.

[0043] In addition, such as Figure 6 As shown:

[0044] A plug 15 is fitted at the bottom of the extension rod 7. A mounting bolt 16 is provided on the outside of the plug 15. The mounting bolt 16 passes through the plug 15 and the extension rod 7 and is threadedly connected to the mounting nut 17. The plug 15 is installed at the bottom of the extension rod 7 by the mounting bolt 16 and the mounting nut 17, so that the plug 15 can be inserted into the soil, maintain the stability of the support foot structure 2, and improve the anti-interference ability.

[0045] In practical use, the adjustable wrench 82 is turned to extend and retract the extension rod 7, and then the adjustable wrench 82 is used to lock the extension rod 7. Then, the support body structure is inserted into the soil through the plug 15. First, the level of the fixed seat 3 is initially adjusted, and then the surveying instrument is installed on the top of the mounting seat 5. Then, the control switch 12 is turned on, and the gyroscope and accelerometer are used to monitor the status of the mounting seat 5. Then, the drive motor 46 is controlled by the control chip. The drive motor 46 drives the drive gear 47 to rotate, and then the drive gear 47 drives the driven gear 45 to rotate the connecting cylinder 42. Then, the connecting cylinder 42 drives the fixed frame 43 to rotate around the fixed shaft 41. The fixed frame 43 then adjusts the angle of the mounting seat 5 in one direction through the movable frame 44. The three sets of movable frames 44 work together to maintain the level of the mounting seat 5. When the support foot structure 2 tilts, the level of the surveying instrument is automatically compensated.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
