[0030] Please refer to Figures 1 to 3 As shown, this embodiment provides an observation lifting device for a total station, comprising: an observation pier 10, a drive assembly 20, a first shielding member 31, and a second shielding member 32. The observation pier 10 has a mounting platform 11, and the total station is mounted on the mounting platform 11; the drive assembly 20 is mounted on the peripheral side of the observation pier 10; the first shielding member 31 is connected to the drive assembly 20 by transmission, and slides relative to the observation pier 10; the second shielding member 32 is connected to the drive assembly 20 by transmission, and slides relative to the observation pier 10, and is surrounded by the first shielding member 31 and the mounting platform 11 to form a receiving space 33, and the total station is located in the receiving space 33 to protect the total station.

[0031] In this embodiment, if Figure 2As shown, the total station is installed on the mounting platform 11, and the first shielding member 31 and the second shielding member 32 are both arc-shaped plates, which together form a complete circular ring, and together with the mounting platform 11 form a receiving space 33. The driving component 20 is mainly a telescopic cylinder, which is installed in the observation pier 10. By controlling the telescopic cylinder, the first shielding member 31 and the second shielding member 32 are driven to move along the axial direction of the observation pier 10, and are buckled on the peripheral side of the mounting platform 11 to form a closed receiving space 33.

[0032] Further, in some implementations of this embodiment, Figures 1 to 3 As shown, a first receiving groove 12 and a second receiving groove 13 are provided on the observation pier 10 , a driving assembly 20 is installed in the first receiving groove 12 and the second receiving groove 13 , a first shielding member 31 is slidably installed in the first receiving groove 12 , and a second shielding member 32 is installed in the second receiving groove 13 .

[0033] In this embodiment, if Figure 2 As shown, there are two first receiving grooves 12 and two second receiving grooves 13, and the two first receiving grooves 12 and the two second receiving grooves 13 are symmetrically distributed on the observation pier 10, and a guide surface is formed between the two first receiving grooves 12 or the two second receiving grooves 13. The first shielding member 31 and the second shielding member 32 have a U-shaped block for auxiliary guidance, which is clamped on the guide surface and slides relative to the extension direction of the guide surface to limit its rotation to improve the stability of the installation. The driving assembly 20 is located in the observation pier 10 and partially extends into the first receiving groove 12 and the second receiving groove 13 to drive the first shielding member 31 and the second shielding member 32.

[0034] Further, in some implementations of this embodiment, Figures 1 to 3 As shown, the cover plate 34 and the connecting member 35 are also included. The cover plate 34 is rotatably mounted on the first shielding member 31 ; the connecting member 35 is installed between the cover plate 34 and the first shielding member 31 , and is used to push the cover plate 34 to rotate toward the second shielding member 32 .

[0035] In this embodiment, if Figure 1 As shown, the cover plate 34 is a circular cover plate 34, and the connecting member 35 can be a servo drive motor cooperating with a hinge structure to control the rotation of the cover plate 34 relative to the first shielding member 31, as shown in FIG. Figure 3 As shown, when the cover 34 is in the open state, the convenience of storing the mask part in the device is further improved, the obstruction to the observation field of view is reduced, and the observation accuracy and convenience are improved.

[0036] Further, in some implementations of this embodiment, Figure 1 to Figure 2As shown, the first shielding member 31 slides along the first receiving groove 12 to the mounting platform 11, and the second shielding member 32 slides along the second receiving groove 13 to the mounting platform 11, and abuts against the first shielding member 31. The connecting member 35 drives the cover plate 34 to rotate and snaps on one end of the first shielding member 31 and the second shielding member 32 to form a accommodating space 33.

[0037] In this embodiment, if Figure 2 As shown, after the first shielding member 31 and the second shielding member 32 are installed on the mounting platform 11 , the cover plate 34 is rotated to shield and close the opening at one end of the accommodating space 33 opposite to the mounting platform 11 .

[0038] Further, in some implementations of this embodiment, Figure 1 As shown, the driving assembly 20 includes: a telescopic rod 21 and a pusher 22. The telescopic rod 21 is installed on the observation pier 10 and moves relative to the observation pier 10; the pusher 22 is slidably installed in the first receiving groove 12 and the second receiving groove 13, the first shielding member 31 and the second shielding member 32 are partially slidably installed in the pusher 22, and the pusher 22 is installed on the telescopic rod 21.

[0039] In this embodiment, if Figure 2 As shown, the telescopic rod 21 can be a telescopic cylinder and a sliding guide rail. The control and driving parts are installed in the observation pier 10. The telescopic part extends into the first receiving groove 12 and the second receiving groove 13 to reduce the influence of the sliding lifting track on the observation angle and range. The first shielding member 31 and the second shielding member 32 are limited and transmitted from both sides by the two first receiving grooves 12 and the two second receiving grooves 13 respectively, so as to improve the stability and reliability of the sliding of the device.

[0040] Further, in some implementations of this embodiment, Figure 3 As shown, a first slot 14 is provided on the mounting platform 11, and the first shielding member 31 and the second shielding member 32 slide onto the mounting platform 11 and are respectively engaged with the inner wall of the first slot 14 to fix the relative position between the first shielding member 31 and the second shielding member 32 and the mounting platform 11.

[0041] In this embodiment, if Figure 3As shown, the first slot 14 is an annular slot, which is distributed along the circumference of the mounting platform 11, and the first slot 14 has an inclined surface, which is convenient for the first shielding member 31 and the second shielding member 32 to slide into the first slot 14, thereby abutting against the inner wall of the slot, thereby improving the installation accuracy and the reliability of fixation. A strip limit block is also provided on the circumferential side of the observation pier 10, which extends along the axial direction of the observation pier 10. One end of the limit block is flush with the inclined surface of the first slot 14. After the first shielding member 31 and the second shielding member 32 slide out of the first slot 14, they abut against the limit block, and then slide out of the first slot 14 along the radial direction of the observation pier 10, thereby releasing the contact between the first shielding member 31 and the second shielding member 32.

[0042] Further, in some implementations of this embodiment, Figure 4 As shown, the driving assembly 20 further includes: a plurality of guide rods 24, a plurality of elastic elements 25, and a rib plate 26. A plurality of mounting holes 23 are provided on the plurality of pushers 22, and the plurality of guide rods 24 are respectively inserted into the plurality of mounting holes 23; the plurality of elastic elements 25 are respectively sleeved on the guide rods 24; and the rib plate 26 is installed on the pusher 22.

[0043] In this embodiment, if Figure 4 As shown, each pusher 22 is provided with four mounting holes 23, and the mounting holes 23 are linear holes. The first shielding member 31 or the second shielding member 32 is partially slidably mounted in the mounting holes 23. There are two layers of mounting holes 23, and each layer has two mounting holes 23, which improves the stability of installation and sliding. The elastic element 25 is specifically a spring, and the guide rod 24 is inserted into each mounting hole 23. Multiple springs improve the stability of the first shielding member 31 and the second shielding member 32 sliding out of the first slot 14 along the radial direction of the observation pier 10. The rib plate 26 improves the structural strength of the pusher 22.

[0044] Further, in some implementations of this embodiment, Figure 4 As shown, it also includes: a plurality of guide blocks 36. The plurality of guide blocks 36 are mounted on the first shielding member 31 and the second shielding member 32, and are slidably mounted in the plurality of mounting holes 23 in a one-to-one correspondence. The plurality of guide blocks 36 are slidably penetrated on the plurality of guide rods 24, and the plurality of elastic elements 25 exert a force away from the central axis of the observation pier 10 on the plurality of guide blocks 36 slidably mounted on the plurality of guide rods 24.

[0045] In this embodiment, if Figure 4 As shown, the guide block 36 corresponds to the four mounting holes 23, and is slidably mounted in the mounting holes 23. The multiple elastic elements 25 drive the first shielding member 31 and the second shielding member 32 from both sides to slide into the first slot 14, thereby increasing the abutment force and thus improving the airtightness. The guide block 36 abuts against the side wall of the mounting hole 23 to improve the stability of the sliding, and the guide rod 24 further improves the accuracy and stability of the sliding.

[0046] Furthermore, in some implementations of this embodiment, the first sealing ring, the second sealing ring, and the sealing strip are also included. The first sealing ring is installed in the first card slot 14; the cover plate 34 is provided with a second card slot 37, and the second sealing ring is installed in the second card slot 37; the sealing strip is installed between the first shielding member 31 and the second shielding member 32.

[0047] In this embodiment, the first sealing ring is installed in the first card slot 14 and is located at the bottom of the inclined surface, abutting against the inner wall of the first shielding member 31 and the second shielding member 32, further improving the sealing performance. The second card slot 37 is an annular groove, and an inclined surface is provided on the inner wall side of the second card slot 37 away from the central axis. The second sealing ring is installed at the bottom of the groove. The cover plate 34 is rotated, and the first shielding member 31 and the second shielding member 32 slide into the second card slot 37 along the inclined surface on the second card slot 37, further improving the sealing performance of the card slot 34 and the first shielding member 31 and the second shielding member 32. There are two sealing strips, which are installed on the side of the arc plate of the first shielding member 31 and the second shielding member 32 to improve the tightness of the side installation and further improve the reliability of the device.

[0048] To summarize, when a total station monitoring and protection device is used to protect the total station, the cover plate 34 is driven to rotate by controlling the connecting member 35 to release the clamping connection between the first shielding member 31 and the second shielding member 32, and the telescopic rod 21 drives the first shielding member 31 and the second shielding member 32 to slide out of the first clamping slot 14, and slide along the extension direction of the first receiving slot 12 and the second receiving slot 13 respectively to lower the first shielding member 31 and the second shielding member 32 and the cover plate 34, thereby reducing the obstruction of the observation angle when using the total station, improving the observation accuracy and the convenience of use, and improving the tightness of the clamping connection between the first shielding member 31 and the second shielding member 32 through the elastic element 25 and the first sealing ring, the second sealing ring and the sealing strip, thereby improving the reliability and stability of the device.

[0049] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
