Description

Technical Field

[0001] The invention relates to the technical field of surveying and mapping instruments, and in particular to a total station measuring scale. Background Art

[0002] When using a total station, ensuring that it is in an accurate horizontal position is crucial to the accuracy of the measurement results. However, existing total station calibration devices have some obvious shortcomings.

[0003] Traditional calibration methods often rely on a single calibration point or a limited number of calibration directions, which makes it difficult to fully and accurately determine whether the total station is in the correct position, resulting in slow calibration speed and poor accuracy.

[0004] In addition, the existing calibration and adjustment mechanism is insufficient in terms of stability and accuracy, and is unable to achieve multi-directional flexible and precise position adjustment. Especially when calibration requirements involve large position differences, it is difficult to provide an effective solution.

[0005] In addition, the bracket design of many total stations lacks flexibility and cannot adapt well to various complex position fine-tuning requirements during the calibration process, affecting the accuracy of the calibration.

[0006] At the same time, the connection method between the existing calibration device and the total station bracket is not reasonable. During use, the rotation operation of the total station may cause errors in the calibrated position, affecting the progress of the measurement work.

[0007] In addition, there are defects in the fixing method of the total station and the calibration device, which cannot effectively guarantee the stability of the total station during use, and is prone to problems such as deflection, affecting the reliability of the measurement results. Summary of the invention

[0008] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a total station measuring scale to solve the above-mentioned technical problems.

[0009] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: A total station measuring scale comprises a total station bracket, a total station body and a calibration body, wherein the total station bracket is installed below the calibration body, the total station body is installed above the calibration body, the calibration body comprises a first bracket, a second bracket and a third bracket, three calibration brackets are equidistantly arranged on the outer side wall of the first bracket, a first threaded rod is fixedly installed on the side wall of each calibration bracket, a first threaded rod is rotatably installed on the top of each calibration bracket, each of the first threaded rods is installed in the first bracket through a thread penetration, a spherical bracket is arranged below the first bracket, a protective bracket is fixedly installed above the second bracket, a spherical tank is fixedly inlaid in the middle of the protective bracket, the spherical bracket below the first bracket is movably installed in the spherical tank, a T-shaped ring bracket is fixedly installed below the second bracket, an upper T-shaped ring groove is provided above the third bracket, and the T-shaped ring bracket below the second bracket is rotatably installed in the upper T-shaped ring groove.

[0010] Preferably: a threaded rod rack is fixedly installed on the top of the first bracket, and the threaded rod rack is installed on the bottom of the total station body through threads, a lower fixing rack is opened at the bottom of the third bracket, and the third bracket is installed on the top of the total station bracket through the lower fixing rack, three threaded holes are opened inside the first bracket close to the calibration frame, each of the first threaded rods is installed in the threaded hole, a lifting frame is fixedly installed on the side wall of each calibration frame, a first spring is fixedly installed between the bottom of each calibration frame and the second bracket, and three fixing frames are fixedly installed at equal intervals on the outer side wall of the first bracket located between the two calibration frames.

[0011] Preferably: a second spring is fixedly installed between the bottom of each of the fixed frames and the second bracket, a telescopic rod is fixedly installed below the middle of the first bracket, the lower end of the telescopic rod is fixedly connected to the spherical bracket, the spherical bracket can be universally rotated when located in the spherical tank, a second threaded rod is fixedly installed on the outer side wall of the first bracket located above one of the fixed frames, a C-shaped frame is provided above the first bracket, a second threaded rod is rotatably installed on the back side of the C-shaped frame, the second threaded rod is threadedly installed in the side fixed frame, and a rectangular plate is rotatably installed on the front side of the C-shaped frame.

[0012] Preferably: three slide rails are provided above the second bracket located below the first threaded rod, a motor is fixedly mounted on the inner wall of each slide rail, a third threaded rod is fixedly mounted on the end of each motor output shaft, the end of each third threaded rod is rotatably connected to the inner wall of the slide rail, a sliding frame is threadedly mounted on the outside of each third threaded rod, a semicircular frame is fixedly mounted above each sliding frame, and the top of each semicircular frame fits with the bottom of the lifting frame.

[0013] (III) Beneficial effects 1: Level meters are provided on multiple surfaces of the first bracket, and each calibration frame is also provided with a level meter. The user can judge whether the total station body is in the correct position according to the multiple level meters, start the multiple motors inside the second bracket, and the operation of the motor drives the sliding frame to move. The movement of the sliding frame will drive the height change of the three sides of the first bracket. The level meter is used to judge whether the calibration of the total station body is completed. By using multiple sliding frames to perform multi-position automatic calibration of the total station body, the calibration speed and accuracy can be improved.

[0014] 2. Start the motor. The motor drives the third threaded rod to rotate. The rotation of the third threaded rod drives the sliding frame to move. The movement of the sliding frame drives the semicircular frame to move. The semicircular frame moves and gradually contacts with the lifting frame. Since the contact surfaces of the semicircular frame and the lifting frame are both arc-shaped, the greater the distance the semicircular frame moves, the greater the upward force on the lifting frame, so that the height of one side of the first bracket is adjusted upward more, and conversely, the height of the first bracket is adjusted downward more. By adopting three-way adjustment, the stability of the total station body during calibration can be improved. At the same time, the calibration of the semicircular frame and the lifting frame can improve the accuracy of position adjustment.

[0015] 3: When the position difference that needs to be calibrated is large, the user can adjust the initial position of the lifting frame. The user rotates the first threaded rod, and the rotation of the first threaded rod drives the calibration frame to move upward or downward as a whole. The movement of the calibration frame will drive the first spring under the calibration frame to expand and contract. By designing the first bracket to be fine-tunable in the initial state, more calibration scenarios can be provided.

[0016] Four: When the first bracket is calibrated, the first bracket will drive the spherical bracket below to rotate, and the spherical bracket will rotate inside the spherical tank. At the same time, the first bracket will fine-tune its position upward or downward. At this time, the first bracket will drive the telescopic rod to extend and retract. By providing a telescopic rod and a spherical bracket between the first bracket and the second bracket, the flexibility of the first bracket during calibration can be improved, and the accuracy of the calibration of the total station body can be further improved.

[0017] 5. When connecting the calibration body to the total station bracket, the user inserts the third bracket into the total station bracket, and rotates the third bracket. The rotation of the third bracket drives the lower fixed bracket to be inserted into the top of the total station bracket, and the third bracket rotates under the second bracket through the upper T-shaped ring groove. When the user uses the total station body, the user can rotate the second bracket as a whole. The rotation of the second bracket drives the T-shaped ring frame to rotate, and the T-shaped ring frame rotates in the upper T-shaped ring groove opened in the second bracket. By designing the second bracket and the third bracket to rotate independently, it is convenient for the user to rotate the total station body for use. At the same time, it can avoid the rotation of the total station body, which leads to a secondary error in the calibrated position, greatly improving the convenience of use after calibration.

[0018] Six: After the total station body and the calibration body are fixed, the user rotates the second threaded rod, and the second threaded rod rotates in the side fixed frame and drives the C-shaped frame to move toward the side wall of the total station body. A torsion spring is arranged between the rectangular plate and the C-shaped frame. When the side wall of the C-shaped frame fits with the side wall of the total station body, the rectangular plate fits with the side wall of the total station body. The C-shaped frame and the rectangular plate can improve the stability of the total station body and prevent the total station body and the second bracket from being skewed when the user rotates the total station body.

[0022] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in view of the problems existing in the prior art, the present invention provides a total station measuring scale, comprising a total station bracket 1, a total station body 11 and a calibration body 2, wherein the total station bracket 1 is installed below the calibration body 2, the total station body 11 is installed above the calibration body 2, the calibration body 2 comprises a first bracket 21, a second bracket 36 and a third bracket 46, three calibration brackets 23 are equidistantly arranged on the outer wall of the first bracket 21, a first threaded rod 25 is fixedly installed on the side wall of each calibration bracket 23, a first threaded rod 25 is rotatably installed above each calibration bracket 23, each first threaded rod 25 is installed in the first bracket 21 through a thread, a spherical bracket 34 is arranged below the first bracket 21, and a second bracket 36 is fixedly installed above the third bracket 46. A protective frame 42 is installed, and levels are provided on multiple surfaces of the first bracket 21. A level is also provided on each calibration frame 23. The user can judge whether the total station body 11 is in the correct position based on the multiple levels. The multiple motors 38 inside the second bracket 36 are started. The operation of the motor 38 drives the sliding frame 4 to move. The movement of the sliding frame 4 will drive the height of the three sides of the first bracket 21 to change. A spherical tank 43 is fixedly inlaid in the middle of the protective frame 42. The spherical frame 34 under the first bracket 21 is movably installed in the spherical tank 43. A T-shaped ring frame 45 is fixedly installed under the second bracket 36. An upper T-shaped ring groove 48 is opened above the third bracket 46. The T-shaped ring frame 45 under the second bracket 36 is rotatably installed in the upper T-shaped ring groove 48.

[0024] A threaded rod frame 35 is fixedly installed on the top of the first bracket 21, and the threaded rod frame 35 is installed on the bottom of the total station body 11 through threads. A lower fixing frame 47 is opened at the bottom of the third bracket 46, and the third bracket 46 is installed on the top of the total station bracket 1 through the lower fixing frame 47. Three threaded holes 22 are opened inside the first bracket 21 close to the calibration frame 23. Each first threaded rod 25 is installed in the threaded hole 22. A lifting frame 24 is fixedly installed on the side wall of each calibration frame 23. The user can adjust the initial position of the lifting frame 24. The user rotates the first threaded rod 25, and the rotation of the first threaded rod 25 drives the calibration frame 23 to move upward or downward as a whole. The movement of the calibration frame 23 will drive the first spring 26 under the calibration frame 23 to expand and contract. By designing the first bracket 21 to be fine-tunable in the initial state, more calibration scenarios can be provided. A first spring 26 is fixedly installed between the bottom of each calibration frame 23 and the second bracket 36, and three fixing frames 27 are fixedly installed equidistantly on the outer wall of the first bracket 21 located between the two calibration frames 23.

[0025] A second spring 28 is fixedly installed between the lower part of each fixing bracket 27 and the second bracket 36, a telescopic rod 33 is fixedly installed at the lower part of the middle part of the first bracket 21, and the lower end of the telescopic rod 33 is fixedly connected to the spherical bracket 34. When the third bracket 46 is rotated, the third bracket 46 drives the lower fixing bracket 47 to be inserted into the upper part of the total station bracket 1, and the third bracket 46 rotates under the second bracket 36 through the upper T-shaped ring groove 48. When the user uses the total station body 11, the user can rotate the second bracket 36 as a whole, and the rotation of the second bracket 36 drives the T-shaped ring bracket 45 to rotate, and the T-shaped ring bracket 45 rotates. The second bracket 36 rotates in the upper T-shaped ring groove 48 provided in the second bracket 36. By designing the second bracket 36 and the third bracket 46 to rotate independently, it is convenient for the user to rotate and use the total station body 11. The spherical bracket 34 can rotate in all directions when located in the spherical tank 43. The outer side wall of the first bracket 21 located above one of the fixed brackets 27 is fixedly installed with the second threaded rod 3. A C-shaped bracket 31 is provided above the first bracket 21. The back side of the C-shaped bracket 31 is rotatably installed with the second threaded rod 3. The second threaded rod 3 is threadedly installed in the side fixed bracket 29. The front side of the C-shaped bracket 31 is rotatably installed with a rectangular plate 32.

[0026] Three slide rails 37 are provided above the second bracket 36 located below the first threaded rod 25. A motor 38 is fixedly installed on the inner wall of each slide rail 37. A third threaded rod 39 is fixedly installed on the end of the output shaft of each motor 38. The operation of the motor 38 drives the third threaded rod 39 to rotate. The rotation of the third threaded rod 39 drives the sliding frame 4 to move. The movement of the sliding frame 4 drives the semicircular frame 41 to move. The semicircular frame 41 moves and gradually contacts the lifting frame 24. Since the contact surfaces of the semicircular frame 41 and the lifting frame 24 are both arc-shaped, the more the semicircular frame 41 moves, the greater the upward force exerted on the lifting frame 24, so that the height of one side of the first bracket 21 is adjusted more upward, and conversely, the height of the first bracket 21 is adjusted more downward. The end of each third threaded rod 39 is rotatably connected to the inner wall of the slide rail 37. The sliding frame 4 is threadedly installed on the outside of each third threaded rod 39. A semicircular frame 41 is fixedly installed above each sliding frame 4, and the top of each semicircular frame 41 is in contact with the bottom of the lifting frame 24.

[0027] Working principle: In the first step, when using the total station body 11, the user first assembles the total station bracket 1, places the total station bracket 1 on the ground, and then installs the calibration body 2 on the total station bracket 1 through the third bracket 46, and then installs the total station body 11 on the threaded rod bracket 35, and then starts to calibrate the total station body 11. Level meters are provided on multiple surfaces of the first bracket 21, and each calibration frame 23 is also provided with a level meter. The user can judge whether the total station body 11 is in the correct position according to multiple level meters, and start multiple motors 38 inside the second bracket 36. The operation of the motor 38 drives the sliding frame 4 to move. The movement of the sliding frame 4 will drive the height of the three sides of the first bracket 21 to change. The level meter is used to judge whether the calibration of the total station body 11 is completed. By using multiple sliding frames 4 to perform multi-position automatic calibration of the total station body 11, the calibration speed and accuracy can be improved.

[0028] In the second step, in the initial state, the multiple first springs 26 and the second springs 28 between the first bracket 21 and the second bracket 36 can keep the total station body 11 balanced. When calibration is required, the motor 38 is started, and the operation of the motor 38 drives the third threaded rod 39 to rotate. The rotation of the third threaded rod 39 drives the sliding frame 4 to move. The movement of the sliding frame 4 drives the semicircular frame 41 to move. The semicircular frame 41 moves and gradually contacts the lifting frame 24. Since the contact surfaces of the semicircular frame 41 and the lifting frame 24 are both arc-shaped, the more the semicircular frame 41 moves, the greater the upward force on the lifting frame 24, so that the height of one side of the first bracket 21 is adjusted upward more, and vice versa, the height of the first bracket 21 is adjusted downward more. By adopting three-way adjustment, the stability of the total station body 11 during calibration can be improved. At the same time, the calibration of the semicircular frame 41 and the lifting frame 24 can improve the accuracy of position adjustment. When the position difference to be calibrated is large, the user can adjust the initial position of the lifting frame 24. The user rotates the first threaded rod 25, and the rotation of the first threaded rod 25 drives the calibration frame 23 to move upward or downward as a whole. The movement of the calibration frame 23 drives the first spring 26 under the calibration frame 23 to expand and contract. By designing the first bracket 21 to be fine-tunable in the initial state, more calibration scenarios can be provided. When the first bracket 21 is calibrated, the first bracket 21 will drive the spherical bracket 34 below to rotate, and the spherical bracket 34 will rotate inside the spherical tank 43. At the same time, the first bracket 21 will fine-tune its position upward or downward. At this time, the first bracket 21 will drive the telescopic rod 33 to extend and retract. By providing a telescopic rod 33 and a spherical bracket 34 between the first bracket 21 and the second bracket 36, the flexibility of the first bracket 21 during calibration can be improved, and the accuracy of the calibration of the total station body 11 can be further improved.

[0029] The third step is that when the calibration body 2 is connected to the total station bracket 1, the user inserts the third bracket 46 on the total station bracket 1, and rotates the third bracket 46. The third bracket 46 rotates to drive the lower fixing bracket 47 to be inserted into the top of the total station bracket 1. At the same time, the third bracket 46 rotates under the second bracket 36 through the upper T-shaped ring groove 48. When the user uses the total station body 11, the user can rotate the second bracket 36 as a whole. The rotation of the second bracket 36 drives the T-shaped ring frame 45 to rotate. The T-shaped ring frame 45 rotates in the upper T-shaped ring groove 48 provided in the second bracket 36. By designing the second bracket 36 and the third bracket 46 to rotate independently, it is convenient for the user to rotate the total station body 11 for use, and at the same time, it can avoid the phenomenon that the total station body 11 rotates and causes a secondary error in the calibrated position, which greatly improves the convenience of use after calibration; After the total station body 11 and the calibration body 2 are fixed, the user rotates the second threaded rod 3, and the second threaded rod 3 rotates in the side fixed frame 29 and drives the C-shaped frame 31 to move toward the side wall of the total station body 11. A torsion spring is arranged between the rectangular plate 32 and the C-shaped frame 31. When the side wall of the C-shaped frame 31 is in contact with the side wall of the total station body 11, the rectangular plate 32 is in contact with the side wall of the total station body 11. The C-shaped frame 31 and the rectangular plate 32 can improve the stability of the total station body 11 and prevent the total station body 11 from being skewed from the second bracket 36 when the user rotates the total station body 11.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
