Description

Technical Field

[0001] This invention relates to a monitoring device, and more particularly to a building safety settlement monitoring device and its usage method, belonging to the field of building construction safety monitoring technology. Background Technology

[0002] Settlement monitoring of buildings is one of the core dynamic risk prevention and control methods in construction safety management. It has irreplaceable special significance for construction safety and is widely used in the field of contemporary construction and building operation safety monitoring.

[0003] The construction phase is a critical period in which the structural stress system of a building gradually forms and is in a highly unstable state. Core procedures such as foundation pit excavation, pile foundation construction, layer-by-layer superposition of main loads, and the erection of temporary support systems all cause a redistribution of foundation stress, which can easily lead to building settlement problems. Settlement monitoring can obtain key indicators such as settlement amount, settlement rate, and uneven settlement difference in real time. When monitoring data shows that the settlement rate accelerates in a short period of time, it often indicates safety hazards such as collapse of the foundation pit sidewall, insufficient bearing capacity of the pile foundation, and shear failure of the foundation soil. If the uneven settlement difference exceeds the standard threshold, it may lead to cracks in the building structure, stress concentration at beam-column joints, and in severe cases, even major accidents such as overall structural tilting and collapse.

[0004] Current building settlement monitoring still relies primarily on manual methods, requiring staff to measure settlement data at each monitoring point on the building individually and manually collect and summarize the data. During construction, to prevent settlement values ​​from exceeding safety thresholds, continuous and high-frequency settlement monitoring is necessary for key components of the building under construction. This process requires staff to frequently move between measurement points, often facing harsh working environments such as muddy sites, high-altitude operations, and dense surrounding obstacles, posing significant safety risks. Furthermore, repeated manual measurements at the same monitoring point are prone to location errors, leading to systematic errors in the obtained settlement data. This compromises the accuracy and reliability of the monitoring results, failing to provide precise data support for construction safety risk prevention and control. Summary of the Invention

[0010] Furthermore, the clamping and moving mechanism includes two symmetrically arranged clamping members, a synchronizing member for driving the two clamping members to move synchronously, a track plate connected inside the device box, a linear track connected to the track plate, and a sliding block slidably connected to the linear track; wherein, when the monitoring rod is inserted into the insertion hole of the device box, the two clamping members are respectively located on both sides of the monitoring rod, and the two clamping members are driven by the synchronizing member to move synchronously relative to each other, thereby completing the clamping and limiting of the monitoring rod; there are two linear tracks, and two sliding blocks are slidably connected to each linear track, and the extension direction of the linear track is perpendicular to the axis of the insertion hole.

[0011] Furthermore, the clamping member includes a roller bracket and two clamping wheels rotatably connected to the roller bracket. The two clamping wheels are arranged axially along the insertion hole. The wheel surfaces of the clamping wheels are in movable contact with the monitoring rod. The roller bracket is connected to a corresponding sliding block. The synchronizing element includes a bidirectional threaded rod, two drive bases, two threaded plates, an extension rod, a driven bevel gear, a driving bevel gear, a turning shaft, and a rotating handle. The two drive bases are respectively connected to the roller supports of the two clamping components. The extension rod is connected to the inner wall of the device housing via a connecting bracket. The two ends of the bidirectional threaded rod pass through the two drive bases and are threadedly connected to the two threaded plates. The threaded plates are slidably connected to the extension rod and are in movable contact with the drive bases. The driven bevel gear is coaxially connected to the bidirectional threaded rod. The turning shaft passes through and is rotatably connected to the device housing. The driving bevel gear is connected to one end of the turning shaft, and the driving bevel gear meshes with the driven bevel gear. The rotating handle is connected to the other end of the turning shaft and is located outside the device housing.

[0012] Furthermore, each of the roller brackets is connected to a telescopic rod, and a telescopic spring is sleeved on the outside of the telescopic rod. The telescopic rod includes a sleeve connected to the inner wall of the device box and a movable rod connected to the sleeve. The movable rod slides along the axial direction of the sleeve. The end of the movable rod is connected to the corresponding roller bracket through a fixed plate. A spring plate is connected to the end of the movable rod away from the sleeve. A threaded part is provided on the outer wall of the sleeve, and an adjusting ring is threadedly connected to it. A push plate is rotatably connected to the side of the adjusting ring near the spring plate. The two ends of the telescopic spring are respectively connected to the spring plate and the push plate.

[0013] Furthermore, after the monitoring rod is inserted into the insertion hole, the rod body inside the device box is connected to a grating ruler by a fixing hoop. The grating ruler extends along the axial direction of the monitoring rod. A reading head device is installed on the track plate, and the grating ruler passes through the sensing end of the reading head device. A level sensor is provided on the device box, and a controller is provided on the device box.

[0014] Furthermore, the pressing mechanism includes a gantry plate connected to the outside of the device box, a pressing rod that passes through and is slidably connected to the top of the gantry plate, a pressing plate connected to the end of the pressing rod, and a push spring sleeved on the outside of the pressing rod; wherein, the two ends of the push spring are respectively connected to the gantry plate and the pressing plate.

[0015] Another object of the present invention is to provide a method for using a building safety settlement monitoring device, the method comprising the following steps: Step 1: Install the mounting rail on the selected building wall using the mounting plate, and set the mounting rail horizontally. Then slide the sliding piece to move the fixed base, device box, rotating mechanism, clamping and moving mechanism and pressing mechanism to the appropriate position. Multiple of the above structures can be arranged as needed, so that settlement monitoring can be carried out at multiple locations. Step 2: Insert the monitoring rod into the device box through the insertion hole, then rotate the double-threaded rod to drive the two threaded plates to move in opposite directions along the extension rod axis. Under the axial force of the telescopic spring, the base is pushed to abut against the threaded plate. As the threaded plate moves, the clamping wheel contacts the monitoring rod. Under the axial force of the telescopic springs on both sides, the two clamping parts form a clamping and limiting state for the monitoring rod. Step 3: After the monitoring rod is installed, when the building settles, the ground pushes the monitoring rod to move longitudinally, which in turn drives the grating ruler to move. The reading head device will sense the moving distance of the monitoring rod and generate a corresponding electrical signal. After the controller detects the electrical signal, it will transmit the data to the background. When the monitoring rod moves, the axial elastic force of the push spring pushes the monitoring rod through the pressing plate, so that the end of the monitoring rod is always in contact with the ground. Step 4: When it is necessary to tilt the monitoring rod to monitor settlement at multiple angles, simply start the drive motor to rotate the rotating base, which in turn causes the monitoring rod to deflect at an angle. When the monitoring rod deflects at an angle, the rotary encoder will detect the deflection angle. Step 5: When it is necessary to remove the monitoring rod, simply rotate the double-threaded rod to drive the two threaded plates to move in opposite directions along the extension rod axis. Under the axial elastic force of the telescopic spring, the base is pushed to abut against the threaded plate. As the threaded plate moves, it pushes the base to move in opposite directions, thereby moving the clamping part away from the monitoring rod and releasing the clamping limit state of the monitoring rod.

[0016] The beneficial effects of this invention are as follows: 1. The mounting rail is fixed to the building wall by the mounting plate. The sliding parts can move flexibly along the mounting rail, driving the fixed base, device box and other overall structures to adjust to the target monitoring position. Multiple sets of the same monitoring structure can be deployed along the mounting rail to realize synchronous settlement monitoring of multiple key areas of the building. There is no need for staff to frequently move back and forth between monitoring points, reducing the intensity of work. 2. This device adopts a collaborative design of grating ruler, reading head device and controller. When the building settles, the monitoring rod drives the grating ruler to move synchronously. The reading head device senses the displacement in real time and converts it into an electrical signal. After being processed by the controller, it is automatically transmitted to the background data system. The staff can remotely obtain core indicators such as settlement amount and settlement rate without the need for on-site manual measurement and data summary. It avoids the operation risks of staff in harsh construction environments such as muddy sites, high-altitude operations and dense surrounding obstacles, and greatly improves the safety of the monitoring process. 3. In this device, the clamping and moving mechanism drives the clamping parts on both sides to move synchronously relative to each other through a bidirectional threaded rod, bevel gear transmission and other synchronous components. With the elastic force of the telescopic spring, the monitoring rod is stably limited. The clamping wheel makes rolling contact with the monitoring rod, which not only ensures that the monitoring rod does not deviate during the monitoring process, but also does not hinder its axial movement, thus solving the problem of point positioning deviation during manual measurement. 4. In this device, the pressing mechanism applies downward pressure to the monitoring rod through the axial force of the spring and the pressing plate, ensuring that the end of the monitoring rod is always in close contact with the ground. This prevents the monitoring rod from being suspended due to uneven ground or instantaneous displacement during settlement, ensuring the continuity of settlement monitoring and reducing measurement errors caused by poor contact. 5. In this device, the rotating mechanism drives the rotating base to rotate through a drive motor, worm gear, and gear transmission, thereby realizing the multi-angle deflection of the monitoring rod. Combined with the angle detection of the rotary encoder, it can comprehensively monitor the settlement of the building in different directions, which solves the limitation of traditional manual monitoring that it is difficult to achieve multi-angle and multi-dimensional settlement analysis. 6. Installation of this device only requires fixing the mounting rail with the mounting plate, and then clamping and limiting the monitoring rod by rotating the handle; disassembly is achieved by rotating the handle in the opposite direction to release the clamp, without the need for a complicated disassembly process. The overall operation is convenient and efficient, allowing for the rapid deployment and adjustment of monitoring points, thus improving the efficiency of settlement monitoring.

Detailed Implementation

[0019] The technical solution of the present invention will be further described in a non-limiting manner below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-8 As shown, this embodiment provides a building safety settlement monitoring device, including: a monitoring rod 1, a mounting rail 2, a sliding component, a fixed base 4, a device box 8, a clamping and moving mechanism 9, and a pressing mechanism 10; The mounting track 2 is connected to the building wall via the mounting plate 3. A sliding member is disposed within the mounting track 2 and slides along its extension direction. A fixed base 4 is mounted on the sliding member, and a rotating shaft 13 is coaxially rotatably connected to the fixed base 4. A rotating base 5 is connected to the rotating shaft 13. The fixed base 4 is equipped with a rotating mechanism 7 for driving the rotating base 5 to rotate. One end of the rotating shaft 13 is equipped with a rotary encoder 6 whose detection end is connected to its end. A device box 8 is connected to the rotating base 5. An insertion hole, suitable for the monitoring rod 1 to pass through, is radially opened on the device box 8 along the rotating base 5. When the monitoring rod 1 is inserted into the insertion hole of the device box 8, the clamping and moving mechanism 9 confines the monitoring rod 1 to the device box 8, allowing the monitoring rod 1 to reciprocate axially along the insertion hole. A pressing mechanism 10 is located above the device box 8 and applies elastic pressing force to the end of the monitoring rod 1. When the monitoring rod 1 is inserted into the insertion hole, the rod body of the monitoring rod 1 located inside the device box 8 is connected to the grating ruler 48 by the fixing hoop 52. The grating ruler 48 extends along the axial direction of the monitoring rod 1. A reading head device 46 is provided at the corresponding position inside the device box 8, and the grating ruler 48 passes through the sensing end of the reading head device 46. A level sensor 45 is provided on the device box 8, and a controller is provided on the device box 8. The level sensor 45, the reading head device 46, and the rotary encoder 6 are electrically connected to the controller. Specifically, the sliding component includes a sliding frame 12 and a plurality of auxiliary wheels 11 rotatably connected to the sliding frame 12; wherein, the sliding frame 12 is disposed in the mounting track 2, the auxiliary wheels 11 are in close contact with the inner wall of the mounting track 2, a connecting frame is connected to the sliding frame 12, one side of the connecting frame extends to the outside of the mounting track 2 and is connected to the fixed base 4, and the rotating shaft 13 is rotatably connected to the fixed base 4 through a bearing component 14.

[0021] First, the mounting track 2 is horizontally fixed to the preset monitoring height on the building wall using the mounting plate 3. The mounting plate 3 is fastened to the wall with expansion bolts to ensure the overall stability of the track. The operator pushes the fixed base 4, causing the sliding component to move along the extension direction of the mounting track 2. The sliding frame 12 in the sliding component is embedded inside the mounting track 2. The auxiliary wheels 11 connected to both sides of the sliding component are in close contact with the inner wall of the track and roll friction, which greatly reduces the movement resistance and allows the entire load-bearing structure to be flexibly adjusted to the target monitoring point. If multiple areas of the building need to be monitored simultaneously, multiple sets of the same structure can be arranged along the mounting track 2 to achieve a full-area coverage monitoring layout. After the position adjustment is completed, the horizontal sensor 45 detects the horizontal state of the device box 8. If there is a tilt, the position of the mounting plate 3 or the sliding component can be finely adjusted until the horizontal sensor 45 feeds back a horizontal signal to the controller to ensure the benchmark accuracy of subsequent monitoring data.

[0022] The rotating mechanism 7 includes a gear ring 15 coaxially connected to the rotating base 5, a bearing base 16 connected to the fixed base 4, a drive bracket 17 connected to the fixed base 4, a drive shaft 18 rotatably connected to the bearing base 16, a drive gear 19 connected to one end of the drive shaft 18, a transmission gear component located at the other end of the drive shaft 18, and a drive motor 20 mounted on the drive bracket 17. Both ends of the drive shaft 18 are rotatably connected to the drive bracket 17. The drive gear 19 meshes with the gear ring 15. The drive motor 20 outputs torque and drives the drive shaft 18 to rotate through the transmission gear component.

[0023] The transmission gear component includes a worm 21 and a worm wheel 22; the worm wheel 22 is fixedly connected to the end of the drive shaft 18 away from the drive gear 19, the worm 21 is rotatably connected to the drive bracket 17, and the worm 21 and the worm wheel 22 are engaged; the output end of the drive motor 20 is connected to the end of the worm 21.

[0024] To monitor building tilt settlement or settlement differences in different directions, the drive motor 20 on the fixed base 4 is activated to rotate the worm gear 21. The worm gear 21 and the worm wheel 22 at the end of the drive shaft 18 drive each other, converting the high-speed rotation into a low-speed stable rotation of the drive shaft 18. The drive gear 19 at one end of the drive shaft 18 meshes with the gear ring 15 on the rotating base 5, causing the rotating base 5 to rotate coaxially around the rotating shaft 13. The rotating shaft 13 is rotatably connected to the fixed base 4 through the bearing 14. The rotary encoder 6 connected to one end of the shaft detects the rotation angle in real time and transmits the angle signal to the controller to achieve accurate measurement of the deflection angle. The rotating base 5 drives the device box 8 and the monitoring rod 1 to deflect synchronously until the preset monitoring angle is reached. The drive motor 20 stops working, and the self-locking characteristic of the worm gear 21 and the worm wheel 22 keeps the monitoring rod 1 at the current stable angle. At this time, by combining the displacement monitoring of the grating ruler 48 and the angle monitoring of the rotary encoder 6, multi-dimensional settlement data can be collected to accurately determine whether there is uneven settlement or tilting risk in the building.

[0025] The clamping and moving mechanism 9 includes two symmetrically arranged clamping members 24, a synchronizing member 23 that drives the two clamping members 24 to move synchronously, a track plate 25 connected inside the device box 8, a linear track 26 connected to the track plate 25, and a sliding block 27 slidably connected to the linear track 26. When the monitoring rod 1 is inserted into the insertion hole of the device box 8, the two clamping members 24 are located on both sides of the monitoring rod 1, and the two clamping members 24 are driven by the synchronizing member 23 to move synchronously relative to each other, thereby completing the clamping and limiting of the monitoring rod 1. There are two linear tracks 26, and two sliding blocks 27 are slidably connected to each linear track 26. The extension direction of the linear track 26 is perpendicular to the axis of the insertion hole. The reading head device 46 is installed on the track plate 25.

[0026] The clamping member 24 includes a roller bracket 28 and two clamping wheels 29 rotatably connected to the roller bracket 28. The two clamping wheels 29 are arranged along the axial direction of the insertion hole. The wheel surface of the clamping wheel 29 is in movable contact with the monitoring rod 1. The roller bracket 28 is connected to the corresponding sliding block 27. The synchronizing element 23 includes a bidirectional threaded rod 30, two drive bases 31, two threaded plates 32, an extension rod 33, a driven bevel gear 34, a driving bevel gear 35, a turning shaft 36, and a rotating handle 37. The two drive bases 31 are respectively connected to the roller brackets 28 of the two clamping elements 24. The extension rod 33 is connected to the inner wall of the device box 8 through a connecting bracket 38. The two ends of the bidirectional threaded rod 30 pass through the two drive bases 31 and are threadedly connected to the two threaded plates 32. The threaded plates 32 are slidably connected to the extension rod 33 and are in movable contact with the drive bases 31. The driven bevel gear 34 is coaxially connected to the bidirectional threaded rod 30. The turning shaft 36 passes through and is rotatably connected to the device box 8. The driving bevel gear 35 is connected to one end of the turning shaft 36 and meshes with the driven bevel gear 34. The rotating handle 37 is connected to the other end of the turning shaft 36 and is located outside the device box 8.

[0027] Each roller bracket 28 is connected to a telescopic rod, and a telescopic spring 39 is sleeved on the outside of the telescopic rod. The telescopic rod includes a sleeve 40 connected to the inner wall of the device box 8 and a movable rod 41 connected to the sleeve 40. The movable rod 41 slides along the axial direction of the sleeve 40. The end of the movable rod 41 is connected to the corresponding roller bracket 28 through a fixing plate. A spring plate 43 is connected to the end of the movable rod 41 away from the sleeve 40. A threaded part is provided on the outer wall of the sleeve 40, and an adjusting ring 42 is threadedly connected to it. A push plate 44 is rotatably connected to the side of the adjusting ring 42 near the spring plate 43. The two ends of the telescopic spring 39 are respectively connected to the spring plate 43 and the push plate.

[0028] The monitoring rod 1 is inserted axially through the insertion hole on the device box 8 until the bottom of the monitoring rod 1 contacts the ground. At this time, rotating the rotating handle 37 outside the device box 8 drives the turning shaft 36 to rotate synchronously. The driving bevel gear 35 at one end of the turning shaft 36 meshes with the driven bevel gear 34 on the bidirectional threaded rod 30, causing the bidirectional threaded rod 30 to rotate circumferentially. Since the threads at both ends of the bidirectional threaded rod 30 have opposite directions and are threadedly connected to two threaded plates 32 respectively, the threaded plates 32 move axially in opposite directions under the guidance of the extension rod 33. At the same time, the threaded plates 32 remain in contact with the driving base 31, and the driving base 31 is connected to the sliding block 27 through the roller bracket 28. The sliding block 27 slides along the linear track 26, thereby pushing the two clamping parts 24 to move synchronously toward the monitoring rod 1.

[0029] The two clamping wheels 29 in the clamping member 24 are arranged along the axial direction of the monitoring rod 1, and the wheel surfaces roll in contact with the surface of the monitoring rod 1, which not only achieves clamping and limiting but also avoids hindering the subsequent axial movement of the monitoring rod 1. During this process, the telescopic rod connected to the roller bracket 28 plays an elastic buffering role: the movable rod 41 of the telescopic rod slides along the axial direction of the sleeve 40, and the two ends of the externally sleeved telescopic spring 39 are respectively connected to the spring plate 43 and the push plate 44. By rotating the adjusting ring 42 on the outside of the sleeve 40, the push plate 44 can be pushed to squeeze the telescopic spring 39, adjusting the spring preload so that the clamping force of the clamping wheel 29 on the monitoring rod 1 is kept within a reasonable range, preventing the monitoring rod 1 from loosening and shifting, and avoiding excessive clamping that would affect its axial movement sensitivity. Finally, with the cooperation of the synchronous transmission mechanism and the elastic clamping structure, the monitoring rod 1 is stably confined within the device box 8, and only retains the reciprocating freedom of movement along the insertion hole axial direction.

[0030] The pressing mechanism 10 includes a gantry plate 47 connected to the outside of the device box 8, a pressing rod 51 that passes through and is slidably connected to the top of the gantry plate 47, a pressing plate 50 connected to the end of the pressing rod 51, and a push spring 49 sleeved on the outside of the pressing rod 51; the two ends of the push spring 49 are respectively connected to the gantry plate 47 and the pressing plate 50.

[0031] When the building settles, the ground will cause the monitoring rod 1 to move longitudinally in sync. At this time, the pressing mechanism 10 above the device box 8 continues to function. The push spring 49 sleeved on the pressing rod 51 on the gantry plate 47 is in a compressed state. Its elastic restoring force is transmitted to the top of the monitoring rod 1 through the pressing plate 50, forming a continuous downward pressing force to ensure that the bottom of the monitoring rod 1 is always in close contact with the ground, avoiding the monitoring rod 1 from being suspended due to uneven ground or instantaneous displacement during settlement, and ensuring the continuity of monitoring. Meanwhile, the grating ruler 48, connected to the monitoring rod 1 via the fixing clamp 52, moves synchronously axially with the monitoring rod 1. The reading head device 46 on the track plate 25 senses the displacement change of the grating ruler 48 in real time, converts the mechanical displacement into a high-precision electrical signal, and transmits it to the controller inside the device box 8. After processing the signal, the controller uploads it to the background data system in real time, allowing staff to remotely obtain core indicators such as settlement amount and settlement rate without on-site manual measurement.

[0032] When the monitoring task is completed or the monitoring point needs to be changed, rotate the handle 37 in the opposite direction to drive the bidirectional threaded rod 30 to rotate in the opposite direction. The threaded plate 32 moves away from the extension rod 33. Under the elastic tension of the telescopic spring 39, the base 31 pulls the clamping part 24 away from the monitoring rod 1, releasing the clamping limit state. The monitoring rod 1 can be removed from the insertion hole by pulling it upward. The entire disassembly process is convenient and efficient, without the need to disassemble other components.

10. The method of using the building safety settlement monitoring device according to any one of claims 1-9, characterized in that: Includes the following steps: Step 1: Install the mounting rail (2) on the selected building wall using the mounting plate (3), and set the mounting rail (2) horizontally. Use the sliding component to move the fixed base (4), device box (8), rotating mechanism (7), clamping and moving mechanism (9) and pressing mechanism (10) to the appropriate position. Multiple of the above structures can be arranged as needed to monitor settlement at multiple locations. Step 2: Insert the monitoring rod (1) into the device box (8) through the insertion hole, rotate the double-threaded rod (30) to drive the two threaded plates (32) to move in opposite directions along the extension rod (33) axially. Under the axial elastic force of the telescopic spring (39), push the base (31) to abut against the threaded plate (32), and move with the threaded plate (32) until the clamping wheel (29) contacts the monitoring rod (1). Under the axial elastic force of the telescopic springs (39) on both sides, the two clamping parts (24) form a clamping limit state on the monitoring rod (1). Step 3: After the monitoring rod (1) is installed, when the building settles, the ground pushes the monitoring rod (1) to move longitudinally, which drives the grating ruler (48) to move. The reading head device (46) senses the moving distance of the monitoring rod (1) and generates a corresponding electrical signal. After the controller detects the electrical signal, it transmits it to the background data. When the monitoring rod (1) moves, the axial elastic force of the push spring (49) pushes the monitoring rod (1) through the pressing plate (50) so that the end of the monitoring rod (1) is always in contact with the ground. Step 4: When it is necessary to tilt the monitoring rod (1) to monitor settlement at multiple angles, simply start the drive motor (20) to rotate the rotating base (5), which in turn causes the monitoring rod (1) to deflect at an angle. When the monitoring rod (1) deflects at an angle, the rotary encoder (6) detects the deflection angle. Step 5: When it is necessary to remove the monitoring rod (1), simply rotate the bidirectional threaded rod (30) to drive the two threaded plates (32) to move in opposite directions along the extension rod (33). Under the axial elastic force of the telescopic spring (39), the base (31) is pushed to abut against the threaded plate (32). As the threaded plate (32) moves, the threaded plate (32) pushes the base (31) to move in opposite directions, so that the clamping part (24) moves away from the monitoring rod (1) and releases the clamping limit state of the monitoring rod (1).
