Description

Technical Field

[0001] The present invention relates to the field of total stations, and specifically to a centering device calibration device and a self-calibration method for a new total station. Background Art

[0002] A total station horizontal axis measuring device refers to a measuring device installed on the horizontal axis of a total station. As a high-precision measuring device, a total station is commonly used in fields such as engineering surveying, civil construction, and road surveying, and can realize functions such as angle measurement and distance measurement in horizontal and vertical directions.

[0003] The existing total station can specifically refer to the total station with the application number: CN202321455840.8, including the total station. By setting bolts that protrude from the top surface of the base, and the bolts can also be slidably connected to the adjustment openings, before the base is inserted into the installation groove, the top ends of the bolts can protrude from the base, facilitating viewing the connection state with the threaded grooves. When the bolts are subjected to downward pressure, they can directly move down along the inner wall of the adjustment openings. The settings of the trays and bearings enable the bolts to be operated from the side trays during the up and down movement, while maintaining the rotatable effect of the bolts. When the position of the base completely fits the inner wall of the installation groove, the rotating knobs can be rotated to thread-fix the bolts on the inner wall of the threaded grooves. During the process, there is only an up and down thrust between the limit blocks and the outer wall of the annular frame. Even if there is a slight micro-vibration, it can be ignored. Finally, as the bolts are thread-fixed with the threaded grooves, the trays can abut against the bottom surfaces of the limit blocks, binding the sliders on the surface of the annular frame to avoid shaking;

[0004] The above-mentioned device does not have components that can be used to facilitate the calibration of the total station centering device. When calibrating the total station centering device, after the total station is installed on the installation table, the support legs at the bottom of the device need to be repeatedly adjusted in position for calibration until the calibration is completed. The operation is cumbersome and the calibration efficiency is low. Therefore, a new total station centering device calibration device and a self-calibration method are proposed for the above problems. Summary of the Invention

Similarly, rotating the first rotating handle 20 at the rear end of the second adjustment table 11 can drive the moving table 12 to move forward and backward for adjustment. A laser alignment line can be formed between the laser emitter 4 above the fixed bracket 3 and the fixed table 2. This baseline can calibrate the device main body 1.

The inner wall of the third fixing seat 19 is designed to be circular;

[0051] During operation, rotate the first rotating handle 20 on the side end of the first adjusting table 10. When the first rotating handle 20 rotates, it drives the first threaded rod 18 to rotate along the inside of the third fixing seat 19, and the first fixing plate 21 at the bottom end of the third fixing seat 19 is used to fixedly support the position of the third fixing seat 19.

[0052] Further, a first rotating handle 20 is welded to one end of the first threaded rod 18, and a rotating block 22 is welded to the other end of the first threaded rod 18.

When the first threaded rod 18 rotates, it drives the rotating block 22 to rotate along the inside of the sleeve block 23.

[0054] Further, second moving blocks 26 are also welded to the front and rear ends inside the first adjusting table 10 and the left and right sides inside the second adjusting table 11. The second guide rod 25 is sleeved outside the second moving block 26, and the second guide rod 25 is slidably connected to the second moving block 26.

[0055] During operation, when the second adjusting table 11 and the moving table 12 move, they also drive the second moving blocks 26 at the bottom ends of the second adjusting table 11 and the moving table 12 to move along the outside of the second guide rod 25.

[0056] Further, three groups of fourth fixing seats 33 are also welded to the bottom end of the fixed table 2. The top end of the fourth fixing seat 33 is sleeved outside the flipping block 34, and the fourth fixing seat 33 is rotatably connected to the flipping block 34. The bottom end of the flipping block 34 is welded to the upper support leg 35, and the inner wall of the flipping block 34 is designed to be circular;

[0057] During operation, the lower support leg 37 is spread outwards, driving the flipping block 34 at the top of the upper support leg 35 to rotate along the outside of the fourth fixed seat 33.

[0058] Furthermore, a second fixing block 36 is welded together at the bottom end of the upper support leg 35. The lower support leg 37 is also sleeved inside the upper support leg 35 and the second fixing block 36. The lower support leg 37 is slidably connected to the upper support leg 35 and the second fixing block 36. A second fixing plate 38 is welded together at the top end of the lower support leg 37;

[0059] During operation, the lower support leg 37 inside the upper support leg 35 is pulled downwards, driving the lower support leg 37 to move downwards along the inside of the upper support leg 35 and the second fixing block 36 at the same time. When the lower support leg 37 moves, it drives the second fixing plate 38 to move, and the second fixing plate 38 can play a limiting role.

[0060] Furthermore, a second threaded rod 39 is sleeved inside the second fixing block 36. The second fixing block 36 is threadedly connected to the second threaded rod 39. One end of the second threaded rod 39 is welded together with a second rotating handle 41. The other end of the second threaded rod 39 is fixedly connected to an extrusion block 40. The extrusion block 40 is designed with a rubber material;

[0061] During operation, the second rotating handle 41 is rotated, driving the second threaded rod 39 to rotate along the inside of the second fixing block 36, and at the same time driving the extrusion block 40 to squeeze the lower support leg 37, thereby fixing the position of the lower support leg 37.

[0062] Furthermore, an assembly component is provided between the moving platform 12 and the device main body 1. The assembly component includes an insertion block 27. The insertion block 27 is arranged at the bottom end of the device main body 1 near the corner. The top end of the insertion block 27 is welded together with the device main body 1. The bottom end of the insertion block 27 is inserted into the first fixing block 28. The insertion block 27 is slidably connected to the first fixing block 28. A stop block 30 is arranged at the top end of the insertion block 27. The insertion block 27 is designed in a conical shape. The top end of the stop block 30 is designed with an inclined surface. One end of a moving rod 29 is welded together with one side of the stop block 30. The first fixing block 28 is sleeved outside the moving rod 29. The first fixing block 28 is slidably connected to the moving rod 29;

[0063] During operation, the insertion block 27 at the bottom end of the device main body 1 is aligned with the first fixing block 28 and inserted. During the insertion process, the insertion block 27 will squeeze the stop block 30 and contract. Since the insertion block 27 is designed in a conical shape and the stop block 30 is designed with an inclined surface, when inserting and squeezing, the stop block 30 is driven to move until it is completely inserted into the first threaded rod 18 through the stop block 30. When the stop block 30 moves, it drives the moving rod 29 to move along the inside of the first fixing block 28.

[0064] Further, a pull plate 31 is welded to the other end of the moving rod 29. A return spring 32 is sleeved outside the moving rod 29. One end of the return spring 32 is welded to the pull plate 31, and the other end of the return spring 32 is welded to the first fixing block 28;

[0065] During operation, the stopper 30 moves, driving the moving rod 29 to move along the inside of the first fixing block 28, and at the same time driving the pull plate 31 to move. When the pull plate 31 moves, it drives the return spring 32 to be stretched. Until the insertion block 27 is completely inserted into the first fixing block 28, under the resilience of the return spring 32, the moving rod 29 and the stopper 30 are driven to return to their original positions, so that the bottom end of the stopper 30 will abut against the insertion block 27.

[0066] Further, a self-calibration method for a new total station centering device, the method comprising the following steps:

[0067] S1. Turn on the laser emitter 4, observe whether the laser point projection coincides with the mechanical centering device mark, and remember the initial direction of the device main body 1;

[0068] S2. Rotate the device main body 1 by 180°, and observe whether the laser point coincides with the mechanical centering device mark; if it coincides, it means that the position of the mechanical centering device is accurate; if it does not coincide, it means that the position of the mechanical centering device is deviated;

[0069] S3. After the position of the mechanical centering device is offset, repeat the operation in the third step, find the middle position of the connection line between the offset point and the original mechanical centering device mark, and define this position as the new mechanical centering device mark;

[0070] S4. Repeat the operation in S2 to check the accuracy of the new mechanical centering device mark;

[0071] S5. Refer to the calibration method of the centering device in JJG 100-2003 "Total Station Electronic Tachometer", move the ground marking platform to align the laser emitter 4 with the center of the ground marking plate, and remember the initial direction of the device main body 1;

[0072] S6. Repeat the operations in S2 and S3. If it is checked that the laser emitter 4 is inaccurate, repeatedly adjust the position of the device main body 1 through the calibration mechanism. The adjustment amount each time is 1 / 2 of the deviation amount until the deviation amount is less than 1 mm;

[0073] S7. After the calibration positioning is accurate, fix the device main body 1 to complete the calibration.

[0074] Working principle: When calibration operation is required, first pull the lower support leg 37 inside the upper support leg 35 downward, driving the lower support leg 37 to move downward along the upper support leg 35 and the second fixed block 36 at the same time, and when the lower support leg 37 moves, it drives the second fixed plate 38 to move, and the second fixed plate 38 can play a limiting effect. After the lower support leg 37 is pulled down, until the fixed platform 2 reaches the chin position of the staff, the second rotating handle 41 is rotated to drive the second threaded rod 39 to rotate along the inside of the second fixed block 36, and at the same time drive the squeezing block 40 to squeeze the lower support leg 37, thereby fixing the position of the lower support leg 37, and then the lower support leg 37 is opened outward to drive the upper support leg 35 The flip block 34 at the top is rotated along the outer side of the fourth fixed seat 33 until the lower support leg 37 is placed on the ground after opening, and the fixed platform 2 is roughly aligned with the landmark point near the middle position, and then the plug block 27 at the bottom end of the device body 1 is aligned with the first fixed block 28 for insertion, and the plug block 27 will squeeze the stopper 30 during the insertion process and shrink. Since the plug block 27 is conical in design and the stopper 30 is inclined in design, the stopper 30 is driven to move during the insertion and extrusion until it is completely inserted into the first threaded rod 18 through the stopper 30, and when the stopper 30 moves, the moving rod 29 is driven to move along the inside of the first fixed block 28, and the pull plate 31 is driven to move at the same time. When the pull plate 31 moves, the retracting The positioning spring 32 is stretched and extended until the plug block 27 is fully inserted into the first fixed block 28, and the moving rod 29 and the stopper 30 are driven to return to their original positions under the rebound force of the return spring 32, so that the bottom end of the stopper 30 will resist the plug block 27. When it needs to be removed, it is only necessary to pull the pull plates 31 on both sides. During the subsequent calibration, the first rotating handle 20 at the side end of the first adjusting platform 10 is first rotated. When the first rotating handle 20 is rotated, the first threaded rod 18 is driven to rotate along the inside of the third fixed seat 19, and the first fixed plate 21 at the bottom of the third fixed seat 19 is used to fix and support the position of the third fixed seat 19. At the same time, when the first threaded rod 18 rotates, it drives the rotating block 22 to rotate along the inside of the sleeve block 23, and the first The threaded rod 18 simultaneously drives the first moving blocks 17 at the front and rear ends to move along the outside of the first threaded rod 18. When the first moving block 17 moves, it will move along the outside of the first guide rod 24. At the same time, when the first moving block 17 moves, it drives the second fixed seat 16 to move, and the movement of the second fixed seat 16 drives the adjusting push rod 15 to rotate along the outside of the second fixed seat 16, and the adjusting push rod 15 rotates along the outside of the first fixed seat 14 at the same time, so that the first fixed seat 14 will push the second adjusting platform 11 to move left and right. Similarly, rotating the first rotating handle 20 at the rear end of the second adjusting platform 11 can drive the moving platform 12 to move forward and backward. When the second adjusting platform 11 and the moving platform 12 move,Similarly, it drives the second adjusting table 11 and the second moving block 26 at the bottom of the moving table 12 to move along the outside of the second guiding rod 25. A laser alignment line can be formed from the laser emitter 4 above the fixed bracket 3 to the fixed table 2. This baseline can calibrate the device main body 1. When the device main body 1 is not installed, the laser emitted by the laser emitter 4 can reach the ground for calibration marking until the calibration is completed.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
