Position positioning helps determine the location of the structure and ensure construction accuracy.

[0003] However, existing devices usually use laser rangefinders to accurately measure long-distance distances, which are suitable for large-scale construction sites. When the laser rangefinder is raised or lowered, due to the high dust content in the construction area, the dust will adhere to the mirror surface of the laser rangefinder during the lifting process, affecting the measurement accuracy of the laser rangefinder.

[0015] The present invention has the following beneficial effects:

[0016] (1) According to the present invention, the device is placed at a construction site, and the telescopic rod is started. The telescopic rod drives the hexagonal plate to move upward, and the hexagonal plate drives the laser rangefinder to move upward. During the upward movement of the laser rangefinder, buildings of different heights can be measured, and the hexagonal plate drives the cylinder to rise, and the cylinder drives the sliding plate to rise. The sliding plate rises inside the load-bearing shell. When the sliding plate moves to the top of the inner wall of the load-bearing shell, it is blocked by the load-bearing shell, and the telescopic rod generates a reaction force. The telescopic rod squeezes the sliding ring to make the sliding ring descend, and the sliding ring drives the rotating plate to descend. The rotating plate drives the fixed ring to descend. Due to the limitation of the support plate, the three fixed rings drive the three support rods to move away from each other, thereby improving the stability of the device during the lifting process.

[0017] (2) According to the present invention, when the sliding plate moves upward inside the load-bearing shell, the sliding plate squeezes the airflow inside the load-bearing shell. Through the setting of the circular hole, the airflow inside the load-bearing shell enters into the cylinder, the airflow enters into the circular tube through the cylinder, and the airflow enters into the square shell through the circular tube. The airflow causes the square plate inside the square shell to slide. When the square plate moves to one end of the curved tube, the airflow entering the square shell will enter into the curved tube, and the airflow enters into the first annular jet through the curved tube. The airflow is discharged to the outside through the first annular jet and sprays the outer wall of the laser rangefinder to prevent dust from adhering to the outer wall of the laser rangefinder, thereby improving the measurement accuracy of the laser rangefinder. Meanwhile, during the movement of the square plate, the square plate drives the round rod to move, the round rod drives the bent plate to move, and the bent plate drives the arc plate to move. The multiple bent plates no longer cover and clamp the laser rangefinder, thereby improving the comprehensiveness of the airflow cleaning the outer wall of the laser rangefinder.

[0018] (3) According to the present invention, when the arc plate moves, the arc plate drives the rotating bar to move, which is limited by the limiting rod. The rotating bar drives the special-shaped lifting plate to descend along the outer wall of the limiting rod. The special-shaped lifting plate drives the round shell to descend. The round shell drives the round plate to descend. The round plate drives the reinforcement frame to descend. During the descent of the reinforcement frame, the top of the laser rangefinder is pressed down, thereby squeezing the laser rangefinder, thereby improving the stability of the laser rangefinder during the lifting process.

[0019] (4) In the present invention, when the reinforcement frame squeezes the laser rangefinder, it is subjected to the reaction force of the laser rangefinder, so that the reinforcement frame drives the circular plate to slide toward the inside of the circular shell. During the sliding process of the circular plate inside the circular shell, the airflow inside the circular shell enters into the inside of the exhaust pipe, and the airflow enters into the inside of the second annular jet through the exhaust pipe. The airflow is discharged to the outside through the second annular jet, thereby spraying the outer wall of the top of the laser rangefinder, further improving the comprehensiveness of the airflow cleaning the outer wall of the laser rangefinder. When the airflow is completely discharged, it is elastically deformed by the reset spring, and the reset spring squeezes the square plate, so that the square plate drives the round rod to move to one end of the inner wall of the square shell, the round rod drives the bent plate to move, the bent plate drives the arc plate to move, and the three arc plates approach each other, thereby clamping the laser rangefinder, thereby improving the accuracy of the laser rangefinder during measurement.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Three limit rods 475 are respectively passed through and slidably connected to the top of the special-shaped lifting plate 474. The purpose of this arrangement is to enable the special-shaped lifting plate 474 to perform lifting movements. The bottom of the limit rod 475 is fixedly connected to the top of the hexagonal plate 451. The bottom of the special-shaped lifting plate 474 is fixedly connected to a round shell 476. The inner wall of the round shell 476 is slidably connected to a round plate 477. The bottom of the round plate 477 is fixedly connected to a reinforcement frame 478.

[0042] In embodiment 2, an auxiliary component 48 is provided on the top of the circular plate 477, and the auxiliary component 48 includes a compression spring 481 fixedly connected to the top of the circular plate 477 away from the reinforcement frame 478, one end of the compression spring 481 is fixedly connected to the top of the inner wall of the circular shell 476, and three exhaust pipes 482 are respectively connected to the top of the circular shell 476.

[0043] One end of the exhaust pipe 482 passes through the special-shaped lifting plate 474 and extends to the outside of the special-shaped lifting plate 474. The end of the exhaust pipe 482 away from the circular shell 476 is connected to the second annular jet 483.

The airflow is discharged to the outside through the second annular jet 483, thereby spraying the outer wall of the top of the laser rangefinder 456, further improving the comprehensiveness of the airflow cleaning the outer wall of the laser rangefinder 456.

[0044] When in use, the device is placed at the construction site, and the telescopic rod 44 is started. The telescopic rod 44 drives the hexagonal plate 451 to move upward, and the hexagonal plate 451 drives the laser rangefinder 456 to move upward. During the upward movement of the laser rangefinder 456, buildings of different heights can be measured, and the hexagonal plate 451 drives the cylinder 452 to rise, and the cylinder 452 drives the sliding plate 453 to rise, and the sliding plate 453 rises inside the load-bearing shell 1. When the sliding plate 453 moves to the top of the inner wall of the load-bearing shell 1, the telescopic rod 44 is blocked by the load-bearing shell 1, and a reaction force is generated by the telescopic rod 44. The telescopic rod 44 squeezes the sliding ring 43 to make the sliding ring 43 descend, and the sliding ring 43 drives the rotating plate 42 to descend, and the rotating plate 42 drives the fixed ring 41 to descend.

The airflow is discharged to the outside through the first annular jet 467, and sprays the outer wall of the laser rangefinder 456 to prevent dust from adhering to the outer wall of the laser rangefinder 456, thereby improving the measurement accuracy of the laser rangefinder 456. Meanwhile, during the movement of the square plate 463, the square plate 463 drives the round rod 465 to move, the round rod 465 drives the bent plate 471 to move, and the bent plate 471 drives the arc plate 472 to move. The multiple bent plates 471 no longer cover and clamp the laser rangefinder 456, thereby improving the comprehensiveness of the airflow in cleaning the outer wall of the laser rangefinder 456.

[0046] When the arc plate 472 moves, the arc plate 472 drives the rotating bar 473 to move, and is limited by the limiting rod 475. The rotating bar 473 drives the special-shaped lifting plate 474 to descend along the outer wall of the limiting rod 475, and the special-shaped lifting plate 474 drives the round shell 476 to descend, and the round shell 476 drives the circular plate 477 to descend, and the circular plate 477 drives the reinforcement frame 478 to descend. During the descent of the reinforcement frame 478, the top of the laser rangefinder 456 is pressed down, thereby squeezing the laser rangefinder 456, thereby improving the stability of the laser rangefinder 456 during the lifting process.

[0047] When the reinforcement frame 478 presses the laser rangefinder 456, the reaction force of the laser rangefinder 456 causes the reinforcement frame 478 to drive the circular plate 477 to slide into the circular shell 476. During the sliding of the circular plate 477 in the circular shell 476, the airflow inside the circular shell 476 enters the exhaust pipe 482, and the airflow enters the second annular jet 483 through the exhaust pipe 482. The airflow is discharged to the outside through the second annular jet 483, thereby spraying the outer wall of the top of the laser rangefinder 456, and entering The comprehensiveness of the airflow cleaning the outer wall of the laser rangefinder 456 is further improved. When the airflow is completely discharged, it is elastically deformed by the return spring 464, and the return spring 464 squeezes the square plate 463, so that the square plate 463 drives the round rod 465 to move to one end of the inner wall of the square shell 462, and the round rod 465 drives the bent plate 471 to move, and the bent plate 471 drives the arc plate 472 to move, and the three arc plates 472 approach each other, thereby clamping the laser rangefinder 456, which indirectly improves the accuracy of the laser rangefinder 456 during measurement.
