Description

Technical Field

[0001] This utility model relates to the field of monitoring technology, and more specifically, to a foundation pit support monitoring device. Background Technology

[0002] Traditional foundation pit support monitoring devices have simple main unit position adjustment mechanisms that lack a precise spatial positioning system. The main unit can only move and adjust in one direction, failing to achieve accurate three-dimensional positioning. Existing devices typically use fixed supports or simple sliding mechanisms, resulting in low adjustment accuracy and large positioning errors, making it difficult to meet the precise monitoring needs in complex foundation pit environments. Especially when monitoring support structures at different depths and angles is required, traditional devices cannot provide sufficient spatial adjustment flexibility.

[0003] The existing angle adjustment mechanism of the monitoring device has significant defects. The rotation adjustment operation of the main unit is complex and cumbersome, requiring multiple tools to complete the angle adjustment. Traditional angle locking mechanisms usually use bolt fastening or clip fixing methods, which are time-consuming to adjust, have poor locking reliability, and are prone to angle deviation or loosening. In actual construction sites, operators need to frequently adjust the monitoring angle to adapt to different monitoring needs, but the angle adjustment efficiency of the existing device is low, which seriously affects the continuity of monitoring work.

[0021] Please see Figures 1-5 A foundation pit support monitoring device includes a mounting plate 1, a monitoring host assembly 2, a space adjustment mechanism, a rotation locking mechanism, and a locking auxiliary mechanism. The space adjustment mechanism includes a rotating plate 3 and a threaded block 4. One end of the rotating plate 3 is rotatably connected to the mounting plate 1. The mounting plate 1 is set inside the foundation pit. A threaded rod 5 is rotatably mounted on the mounting plate 1, and the threaded block 4 is threadedly connected to the threaded rod 5. The monitoring host assembly 2 is mounted on the threaded block 4. An adjustment plate 6 is mounted on the side of the rotating plate 3, and the adjustment plate 6 has an adjustment hole 7. Multiple sets of joint holes 7 are provided. The rotating snap-fit ​​mechanism includes a support tube 8 and a snap-fit ​​rod 9. A snap-fit ​​tube 10 is installed on the top end of the support tube 8 for limiting rotation. A fixing block 11 is installed on the outer wall of the snap-fit ​​rod 9. A rotating sleeve block 12 is installed on the inner wall of the snap-fit ​​tube 10. A bidirectional spring rod 13 is installed on the fixing block 11. Multiple sets of rotating sleeve blocks 12 and fixing blocks 11 are provided. The rotation of rotating sleeve blocks 12 causes rotating sleeve blocks 12 to fit the fixing block 11. A snap-fit ​​groove 14 is opened on rotating sleeve blocks 12. The bidirectional spring rod 13 can extend into the snap-fit ​​groove 14.

[0022] In this embodiment, after the mounting plate 1 is fixed in the pit, the rotating plate 3 is reliably rotated through the support seat 22 and the support bearing 23. The operator starts the drive assembly 26, which drives the threaded rod 5 to rotate, so that the threaded block 4 slides smoothly along the guide rail 24 on the threaded rod 5. The threaded block 4 drives the monitoring host assembly 2 to make linear displacement adjustment on the rotating plate 3, so as to achieve precise adjustment of the monitoring position. At the same time, by adjusting the angle relationship between the rotating plate 3 and the mounting plate 1, and with the selection of multiple sets of adjustment holes 7 on the adjustment plate 6, the monitoring host assembly 2 can be adjusted in all directions in space. The locking rod 9 passes through the selected adjustment hole 7 on the adjustment plate 6 and extends into the support tube 8. The fixing block 11 and the rotating sleeve block 12 begin to make contact. The operator rotates the locking tube 10, so that the rotating sleeve block 12 gradually fits the fixing block 11. As the rotation is in place, the bidirectional spring rod 13 automatically extends into the slot 14 on the rotating sleeve block 12, forming a bidirectional locking mechanism to ensure a firm connection between the locking rod 9 and the locking tube 10, thereby locking the rotating plate 3 at a specific angle position.

[0023] The locking auxiliary mechanism includes an outer retaining ring 15 and a clamping spring rod 16. A driving sleeve 17 is installed on the outer wall of the locking tube 10. A rotating ring 18 is installed at the bottom end of the driving sleeve 17. A friction groove 19 is opened on the rotating ring 18. The outer retaining ring 15 is fixedly installed on the outer wall of the support tube 8. A clamping spring rod 16 is installed on the outer retaining ring 15. An outer rotating sleeve 20 is installed on the upper limit of the outer retaining ring 15. A spinning plate 21 is installed at the top end of the outer rotating sleeve 20. The spinning plate 21 presses against the clamping spring rod 16, so that the clamping spring rod 16 extends into the friction groove 19, thereby fixing the rotating ring 18 and the locking tube 10 on the support tube 8.

[0024] In this embodiment, when the operator rotates the sleeve 17 to rotate the clamping tube 10, the rotating ring 18 at the bottom of the sleeve 17 rotates accordingly. At the same time, the operator rotates the outer rotating sleeve 20, causing the pressure plate 21 to press against the clamping spring rod 16. Under pressure, the clamping spring rod 16 extends into the friction groove 19 on the rotating ring 18, forming a stable friction lock. This ensures the rotational accuracy and locking reliability of the clamping tube 10 on the support tube 8, preventing accidental loosening or displacement during operation. Reverse rotation of the outer rotating sleeve 20 moves the clamping spring rod 16 away from the friction groove 19. Simultaneously, rotation of the clamping tube 10 releases the locking of the rotating sleeve block 12 and the fixing block 11, thus disengaging the clamping tube 10 from the clamping rod 9.

[0025] Please see Figures 1-5As a supplementary implementation method for a foundation pit support monitoring device, which includes a space adjustment mechanism, a rotation locking mechanism, and a locking auxiliary mechanism: Support seats 22 are symmetrically installed on the top end of the mounting plate 1. The two ends of the rotating plate 3 are rotatably configured to cooperate with the support seats 22. Support bearings 23 are installed on the support seats 22, and the two ends of the rotating plate 3 are connected to the support bearings 23. Guide rails 24 are symmetrically installed on the rotating plate 3. Guide sleeves 25 are installed on both sides of the threaded block 4, and the guide sleeves 25 and guide rails 24 are slidably guided. A drive assembly 26 is installed on the rotating plate 3. The output end of the drive assembly 26 is connected to one end of the threaded rod 5. A longitudinal plate 27 is installed on the top end of the support base 22. The support tube 8 is fixedly installed on the longitudinal plate 27. The snap-fit ​​rod 9 can pass through different adjustment holes 7 and extend through the longitudinal plate 27 to quickly snap-fit ​​with the support tube 8 and the snap-fit ​​tube 10. An inner retaining ring 28 is installed on the inner wall of the support tube 8. A thrust spring 29 is installed on the outer wall of the snap-fit ​​rod 9. One end of the thrust spring 29 can contact the bottom end of the inner retaining ring 28.

[0026] More specifically, the mounting plate 1 is fixed in the pit to ensure the overall stability of the device. By operating the drive assembly 26 to rotate the threaded rod 5, the monitoring host assembly 2 is smoothly slid to the appropriate position on the guide rail 24. At the same time, the angle of the rotating plate 3 is adjusted to align with the optimal monitoring direction. The appropriate adjustment hole 7 on the adjustment plate 6 is selected, and the locking rod 9 is passed through and inserted into the support tube 8. The locking tube 10 is rotated so that the rotating sleeve block 12 fits the fixing block 11. The bidirectional spring rod 13 is automatically locked into the slot 14 to achieve precise locking of the angle of the rotating plate 3. The outer rotating sleeve 20 is rotated so that the spinning plate 21 presses against the clamping spring. Rod 16, the compression spring rod 16 extends into the friction groove 19 of the rotating ring 18 to form a secondary locking protection, ensuring the long-term stability of the monitoring angle. The monitoring host component 2 continuously monitors the foundation pit support in a fixed spatial position, collects data and transmits it to the control center. When the monitoring position needs to be adjusted, the outer rotating sleeve 20 is rotated in the opposite direction, the compression spring rod 16 moves away from the friction groove 19, and the locking pipe 10 is rotated at the same time to release the locking of the rotating sleeve block 12 and the fixed patch block 11, so that the locking pipe 10 is released from the locking rod 9, and the spatial position and monitoring angle are readjusted to adapt to the dynamic changes in the foundation pit construction.

[0027] In summary, when the overall equipment is in use or operation: when the space adjustment mechanism is required, after the mounting plate 1 is fixed in the pit, the rotating plate 3 is reliably rotated through the support seat 22 and the support bearing 23. The operator starts the drive assembly 26, which drives the threaded rod 5 to rotate, so that the threaded block 4 slides smoothly along the guide rail 24 on the threaded rod 5. The threaded block 4 drives the monitoring host assembly 2 to make linear displacement adjustment on the rotating plate 3, so as to achieve precise adjustment of the monitoring position. At the same time, by adjusting the angle relationship between the rotating plate 3 and the mounting plate 1, and with the selection of multiple sets of adjustment holes 7 on the adjustment plate 6, the monitoring host assembly 2 can be adjusted in all directions in space.

[0028] When the locking mechanism needs to be rotated, the locking rod 9 passes through the selected adjustment hole 7 on the adjustment plate 6 and extends into the support tube 8. The fixed patch 11 and the rotating sleeve block 12 begin to engage and contact. The operator rotates the locking tube 10 so that the rotating sleeve block 12 gradually fits the fixed patch 11. As the rotation is completed, the bidirectional spring rod 13 automatically extends into the slot 14 on the rotating sleeve block 12, forming a bidirectional locking mechanism to ensure a firm connection between the locking rod 9 and the locking tube 10, thereby locking the rotating plate 3 at a specific angle position.

[0029] When the auxiliary locking mechanism is in operation, the operator rotates the locking tube 10 by driving the sleeve 17, which in turn causes the rotating ring 18 at the bottom of the sleeve 17 to rotate. At the same time, the operator rotates the outer rotating sleeve 20, causing the pressure plate 21 to press against the clamping spring rod 16. Under pressure, the clamping spring rod 16 extends into the friction groove 19 on the rotating ring 18, forming a stable friction lock. This ensures the rotational accuracy and locking reliability of the locking tube 10 on the support tube 8, preventing accidental loosening or displacement during operation. Reverse rotation of the outer rotating sleeve 20 moves the clamping spring rod 16 away from the friction groove 19. Simultaneously, rotation of the locking tube 10 releases the locking of the rotating sleeve block 12 and the fixed patch block 11, thus disengaging the locking tube 10 from the locking rod 9.

[0030] Fix the mounting plate 1 in the pit to ensure the overall stability of the device. Rotate the threaded rod 5 by operating the drive component 26 to make the monitoring host component 2 slide smoothly on the guide rail 24 to the appropriate position. At the same time, adjust the angle of the rotating plate 3 to align with the optimal monitoring direction. Select the appropriate adjustment hole 7 on the adjustment plate 6, pass the locking rod 9 through and insert it into the support tube 8. Rotate the locking tube 10 to make the rotating sleeve block 12 fit the fixing block 11. The bidirectional spring rod 13 automatically locks into the slot 14 to achieve precise locking of the angle of the rotating plate 3. Rotate the outer rotating sleeve 20 to make the spinning plate 21 press against the clamping spring rod 16. The compression spring rod 16 extends into the friction groove 19 of the rotating ring 18 to form a secondary locking protection, ensuring the long-term stability of the monitoring angle. The monitoring host component 2 continuously monitors the foundation pit support in a fixed spatial position, collects data and transmits it to the control center. When the monitoring position needs to be adjusted, the outer rotating sleeve 20 is rotated in the opposite direction, the compression spring rod 16 moves away from the friction groove 19, and the locking pipe 10 is rotated at the same time to release the locking of the rotating sleeve block 12 and the fixed patch block 11, and to release the locking pipe 10 from the locking rod 9, so that the spatial position and monitoring angle can be readjusted to adapt to the dynamic changes in the foundation pit construction.
