Description

Technical Field

[0001] This invention relates to the field of foundation pit inclination measurement technology, specifically providing a deep foundation pit inclination measurement and positioning device in soft soil areas. Background Technology

[0002] In deep foundation pit engineering in soft soil areas, inclinometer monitoring is one of the core means to ensure the safety of foundation pit construction. Inclinometer monitoring involves measuring the change in inclination angle of the inner wall of the inclinometer tube embedded in the retaining structure or soil using an inclinometer, thereby indirectly calculating the horizontal displacement.

[0003] Existing inclinometer positioning devices include: an inclinometer probe, an inclinometer cable, and a reading instrument, among which:

[0004] The inclinometer probe is equipped with sensors such as an accelerometer and has two sets of guide wheels at the top and bottom. The guide wheels can move up and down and be positioned along the guide groove of the inclinometer tube, allowing the probe to move stably inside the inclinometer tube and accurately measure the inclination angle of the inclinometer tube axis relative to the plumb line at different depths.

[0005] Inclinometer cables are used not only to connect the probe and the reading instrument and transmit sensor signals, but also as a scale for the probe's test points and a rope for raising and lowering the probe. The cables are usually marked at regular intervals, such as every 0.5m, to facilitate determining the probe's depth.

[0006] The reader is used to receive signals from the probe and convert them into readable values ​​or data, displaying information such as the tilt angle or horizontal displacement of the inclinometer tube at various depths.

[0007] However, existing inclinometer positioning devices do not have the function of replacing damaged pipelines. That is, after the pipeline is damaged, the entire pipeline section must be replaced manually. This operation is inefficient and easily leads to pipeline waste. Summary of the Invention

[0076] The following is combined Figures 1 to 14 The illustrated embodiments describe the technical solution of the present invention:

[0077] This invention provides a device for inclination measurement and positioning of deep foundation pits in soft soil areas, such as... Figures 1 to 3 As shown, it includes: a base plate 1, a tilting probe 2, a first walking mechanism 3, a rotating disk assembly 4, a first cantilever 5, a first telescopic mechanism 6, a second cantilever 7, a third cantilever 8, a bolt fastening mechanism 9, a control module 10, and an adsorption assembly 11.

[0078] The inclinometer probe 2 is coaxially mounted on the base plate 1; the first traveling mechanism 3 is located on the base plate 1 and is used to drive the base plate 1 to move within the pipe being measured; the rotating disk assembly 4 is coaxially mounted with the base plate 1 and rotatably mounted on the base plate 1; there are at least two first cantilever arms 5, each with its rotation center as the center of the rotating disk assembly 4, arranged in a ring around the rotating disk assembly 4; one end of each first cantilever arm 5 is located on the rotating disk assembly 4, and the other end extends along the axial direction of the base plate 1, allowing the first cantilever arm 5 to rotate with the rotating disk assembly 4; one end of the first telescopic mechanism 6 is located on the base plate 1. A cantilever 5; a second cantilever 7 is connected to the other end of the first telescopic mechanism 6 and can move telescopically with the first telescopic mechanism 6; multiple adsorption components 11 are provided on the second cantilever 7; at least two third cantilever 8 are provided at both ends of the second cantilever 7; a bolt fastening mechanism 9 is provided on the second cantilever 7 and the third cantilever 8 and is used to tighten or loosen the bolts in the pipe being tested; the control module 10 is electrically connected to the inclination probe 2, the first walking mechanism 3, the rotating disk assembly 4, the first telescopic mechanism 6, the adsorption components 11 and the bolt fastening mechanism 9 respectively.

[0079] In some embodiments, the first cantilever 5 may have four sets, which can achieve the disassembly of the old pipe arc plate by controlling other second cantilever 7 and third cantilever 8 through other first cantilever 5 while carrying the new pipe arc plate.

[0080] In this embodiment, the base plate 1 provides the mounting foundation for other components, and when combined with the first walking mechanism 3, it enables the overall movement of the device. The inclinometer probe 2 is coaxially mounted on the base plate 1, and can accurately measure the inclination angle of the inclinometer tube axis relative to the vertical line at different depths. The rotating disk assembly 4 can drive the first cantilever 5 to rotate around the axis of the base plate 1. The fixed end of the first telescopic mechanism 6 is set on the first cantilever 5, and the telescopic end is connected to the second cantilever 7, which can drive the second cantilever 7 to telescopically move, thereby meeting the replacement needs of pipes of different sizes. At the same time, multiple adsorption components 11 are set on the second cantilever 7, which can allow the pipe arc plate to be attached to the second cantilever 7 through the adsorption components 11. Third cantilever 8 is set at both ends of the second cantilever 7, and bolt fastening mechanisms are set on the second cantilever 7 and the third cantilever 8. 9. By controlling the extension of the first telescopic mechanism 6, the bolt fastening mechanism 9 on the second cantilever 7 and the third cantilever 8 is driven to contact the bolts on the arc plate of the pipe to be replaced. Thus, by reversing the fastening head on the bolt fastening mechanism 9, the mounting nut on the old arc plate of the pipe is removed, thus completing the preliminary action for replacing the new arc plate of the pipe. At this time, the control module 10 causes the rotating disk assembly 4 to rotate, thereby rotating the new arc plate of the pipe carried on the first cantilever 5 to the installation position of the old arc plate of the pipe. The adsorption assembly 11 is controlled to extend, so that the new arc plate is completely aligned with the installation position of the old arc plate. The first telescopic mechanism 6 is controlled to extend, and the pre-installed nut on the bolt fastening mechanism 9 is inserted into the mounting screw on the new arc plate. At the same time, the bolt fastening mechanism 9 is started to pre-tighten the nut, thus realizing the replacement of the arc plate of the pipe.

[0081] This invention provides a tilt-measuring and positioning device for deep foundation pits in soft soil areas. By improving the traditional tilt-measuring and positioning device into a novel device with a damaged pipeline replacement function, it effectively solves the problem that existing tilt-measuring and positioning devices do not have this function. Specifically:

[0082] By setting up the first cantilever 5, the second cantilever 7, the third cantilever 8 and the adsorption component 11, it is possible to carry the new pipe arc plate and to adsorb and fix the old pipe arc plate that has been damaged.

[0083] By setting the first telescopic mechanism 6, the overall extension and shortening of the first cantilever 5, the second cantilever 7, the third cantilever 8 and the adsorption component 11 can be realized to adapt to the installation of the new pipe arc plate and the disassembly and retraction of the old pipe arc plate.

[0084] The bolt fastening mechanism 9 allows for the tightening and loosening of bolts on the inner wall of the tested pipe, enabling the disassembly of the old pipe arc plate and the installation and fastening of the new pipe arc plate.

[0085] When the inclinometer positioning device enters the pipe being measured, the new pipe arc plate is adsorbed onto the adsorption component 11. At the same time, multiple fastening nuts are magnetically attracted to the bolt fastening mechanism 9. When the inclinometer positioning device reaches the target position, i.e. the position to be replaced, first control the rotating disk component 4 to rotate, and rotate the cantilever that does not carry the new pipe arc plate to one end of the old pipe arc plate, and face the old pipe arc plate. At the same time, the fastening heads on the bolt fastening mechanism 9 are required to be aligned with the mounting nuts of the old pipe arc plate. Then control the first telescopic mechanism 6 to extend. When the mounting nuts of the old pipe arc plate are engaged with the fastening heads, the adsorption component 11 also abuts against the inner wall of the old pipe arc plate. Then control the adsorption component 11 to adsorb, and at the same time control the fastening heads on the bolt fastening mechanism 9 to rotate in the opposite direction to remove the mounting nuts. Then control the first telescopic mechanism 6 to retract.

[0086] Then, control the rotating disk assembly 4 to rotate until the new pipe arc plate is aligned with the installation position of the old pipe arc plate that was just removed. Then, control the adsorption assembly 11 to extend until the new pipe arc plate is in the installation position. Then, control the adsorption assembly 11 to shorten, and at the same time control the first telescopic mechanism 6 to extend until the pre-installed nut on the fastening head of the bolt fastening mechanism 9 is engaged with the installation screw of the new pipe arc plate. Then, start the bolt fastening mechanism 9 to tighten the nut. Then, release and retract the adsorption assembly 11 to complete the replacement.

[0087] According to the embodiments of the present invention, the inclinometer positioning device, such as Figure 4 and Figure 6 As shown, the rotary disk assembly 4 includes: a positioning ring 401, a support ring 402, a first ball ring groove 403, a gear disk 404, a support groove 405, a second ball ring groove 406, and a second drive mechanism 407.

[0088] The positioning ring 401 is coaxially connected to the bottom of the base plate 1, and the lower end face of the positioning ring 401 is fixed with a support ring 402 along the circumferential direction. The upper and lower surfaces of the support ring 402 are coaxially provided with a first ball ring groove 403.

[0089] The gear disk 404 has an annular support groove 405 coaxially formed on its end face. The support groove 405 and the support ring 402 are installed together. The upper and lower end faces of the inner cavity of the support groove 405 are both coaxially formed with a second ball ring groove 406, which corresponds to the first ball ring groove 403. Multiple balls are arranged between the first ball ring groove 403 and the second ball ring groove 406.

[0090] The second drive mechanism 407 is connected to the gear disk 404 and is also electrically connected to the control module 10, and is used to drive the gear disk 404 to rotate.

[0091] In some embodiments, the second drive mechanism 407 may be a motor drive combined with gears or planetary gears, or a combination of chain and belt, to transmit power from a gear to the gear disk 404;

[0092] In this embodiment, the second drive mechanism 407 is preferably a combination of motor-driven gears, which transmits the rotation of the motor to the gear disk 404. At the same time, a support ring 402 is fixed to the lower end face of the positioning ring 401. The support ring 402 cooperates with the support groove 405 on the gear disk 404, providing a rotation support point for the rotation of the gear disk 404. Meanwhile, the first ball ring groove 403 on the support ring 402 and the second ball ring groove 406 on the support groove 405 cooperate, and multiple balls are arranged between the ring grooves, so that the rotation of the gear disk 404 will not be reduced due to the friction between the support ring 402 and the support groove 405, ensuring its normal operation.

[0093] According to the embodiments of the present invention, the inclinometer positioning device, such as Figure 7 As shown, the first walking mechanism 3 includes: a walking gear set 301, a walking wheel 3011, a rack 302, and a first drive mechanism 303;

[0094] The traveling gear set 301 has multiple traveling wheels 3011, all of which are set with their axes perpendicular to the axis of the base plate 1 and are rotatably mounted on the edge of the base plate 1. Part of the traveling gear set 301 protrudes from the base plate 1. The traveling gear set 301 is used to mesh with the rack 302 set axially along the inner wall of the pipe being measured.

[0095] The first drive mechanism 303 is connected to the walking gear set 301 and is used to drive the walking gear set 301 to rotate in both directions.

[0096] In some embodiments, the first drive mechanism 303 may be a motor drive combined with gears or planetary gears, or a combination of chain and belt, which can directly transmit power to the walking wheel 3011;

[0097] In this embodiment, the first driving mechanism 303 is preferably a single stepper motor directly connected to the walking wheel 3011, and the other walking wheels 3011 are driven wheels. The movement of the entire first walking mechanism 3 can be controlled by a single motor. At the same time, the part of the walking wheel 3011 protruding from the base plate 1 meshes with the rack 302 axially arranged on the inner wall of the pipe being tested. By controlling the forward and reverse rotation of the first driving mechanism 303, the up and down movement of the first walking mechanism 3 on the rack 302 can be realized, thereby realizing the detection of various positions of the pipe wall and the replacement of the pipe wall arc plate.

[0098] According to the embodiments of the present invention, the inclinometer positioning device, such as Figure 2 and Figure 8As shown, it also includes a wheeled distance measuring mechanism 12, which is connected to the walking gear set 301 and electrically connected to the control module 10.

[0099] In this embodiment, the wheel-type distance measuring mechanism 12 is connected to the walking gear set 301. By recording the number of rotations N of the walking gear set 301 during the use of the device, and the wheel circumference R of the walking gear set 301, the position L of the device in the pipe to be tested can be obtained. Since L = NR, the wheel-type distance measuring mechanism 12 can be used to determine where the problem is in the pipe, providing data basis for subsequent replacement.

[0100] According to the embodiments of the present invention, the inclinometer positioning device, such as Figure 2 and Figure 9 As shown, it also includes:

[0101] The wireless transmission module 13 is located in the inclinometer positioning device and is electrically connected to the control module 10.

[0102] Multiple cameras 14 are installed on the first cantilever 5 and electrically connected to the control module 10.

[0103] The receiving and control terminal 15 is wirelessly connected to the wireless transmission module 13.

[0104] In this embodiment, the wireless transmission module 13, the camera 14, and the receiving and control terminal 15 form a real-time image interaction module. The wireless transmission module 13 transmits the data obtained by the inclinometer probe 2 and the wheel-type distance measuring mechanism 12 in the positioning device to the receiving and control terminal 15. The receiving and control terminal 15 then controls the operation of the device to ensure its normal operation. At the same time, multiple cameras 14 are installed on the first cantilever 5. Through the real-time scene transmitted by the cameras 14, the inspection personnel can control the normal operation of the device in the pipeline, complete the inclinometer positioning, and replace the pipeline arc plate.

[0105] According to the embodiments of the present invention, the inclinometer positioning device, such as Figure 10 As shown, the adsorption assembly 11 includes: a suction cup 1101, a vacuuming mechanism 1102, and a second telescopic mechanism 1103;

[0106] The vacuum mechanism 1102 is connected to the suction cup 1101 and communicates with the inner cavity of the suction cup 1101; one end of the second telescopic mechanism 1103 is connected to the second cantilever 7, and the other end is connected to the vacuum mechanism 1102.

[0107] In some embodiments, the second telescopic mechanism 1103 can be a combination of a pneumatic cylinder, an electric cylinder, or a servo motor and a telescopic rod. The second telescopic mechanism 1103 can provide pressure to the pipe arc plate by the suction cup 1101, ensuring that the suction cup 1101 can adsorb the arc plate under the vacuum mechanism 1102. At the same time, the second telescopic mechanism 1103 can drive the suction cup 1101 to move.

[0108] In this embodiment, the second telescopic mechanism 1103 is preferably a combination of a servo motor and a movable rod. The movement of the second telescopic mechanism 1103 on the second cantilever 7 drives the suction cup 1101 to contact the arc plate to be replaced. After contact is completed, it extends and retracts slightly in the contact direction to apply appropriate pressure to the arc plate to be replaced. The vacuum mechanism 1102 is activated so that the suction cup 1101 adsorbs the arc plate to be replaced. The arc plate to be replaced is disassembled by the bolt fastening mechanism 9. The second telescopic mechanism 1103 is retracted to complete the disassembly of the arc plate, which is a preliminary action for subsequent replacement.

[0109] According to the embodiments of the present invention, the inclinometer positioning device, such as Figure 11 As shown, the traveling gear set 301 includes:

[0110] A bracket 3012 is connected to a base plate 1; multiple traveling wheels 3011 are arranged sequentially along the axial direction of the base plate 1 and are rotatably mounted on the bracket 3012; a first drive mechanism 303 includes: a first motor 3031 mounted on the base plate 1; multiple first transmission rods 3032, with the same number as the traveling gear set 301, with first conical teeth 30321 coaxially mounted at both ends of the first transmission rods 3032, and first transmission spur teeth 30322 coaxially mounted on the first transmission rods 3032; multiple first transmission rods 3032 mesh head-to-tail to form a closed-loop structure, and are all rotatably mounted on the base plate 1; multiple second force transmission spur teeth 3033, with the same number as the first transmission spur teeth 30322, are rotatably mounted on the base plate 1 and mesh with the first transmission spur teeth 30322; the second force transmission spur teeth 3033 also mesh with the traveling wheels 3011.

[0111] In this embodiment, the first motor 3031 is mounted on the base plate 1 and coaxially mounted with the second power transmission spur gear 3033, driving the second power transmission spur gear 3033 to rotate. Simultaneously, the second power transmission spur gear 3033 meshes with the first transmission spur gear 30322, thereby driving the first transmission spur gear 30322 to rotate. The first transmission spur gear 30322 is coaxially mounted on the first transmission rod 3032, thus driving the first transmission rod 3032 to rotate. First conical teeth 30321 are coaxially mounted at both ends of the first transmission rod 3032, and adjacent first conical teeth 30321 are meshed together. Therefore, through a single first motor 3031... 31 can drive multiple first conical teeth 30321 and first transmission rod 3032 to rotate, and drive the first transmission spur teeth 30322 on the first transmission rod 3032 to rotate, thereby driving the second force transmission spur teeth 3033 meshing with the first transmission spur teeth 30322 to rotate. The second force transmission spur teeth 3033 also mesh with the traveling wheel 3011, so that the entire traveling wheel 3011 can be driven to rotate by a first motor 3031. Thus, under the rotation of the traveling gear set 301, the entire device is driven to move along the preset rack 302 in the pipeline, realizing the inclination measurement of various points in the pipeline and the replacement of the pipeline arc plate.

[0112] According to the embodiments of the present invention, the inclinometer positioning device, such as Figure 2 and Figure 12 As shown, the bolt fastening mechanism 9 includes:

[0113] The second motor 901 is mounted on the second cantilever 7 and has a third bevel gear 902 coaxially outputting.

[0114] The second transmission rod 903 has multiple parts, some of which are rotatably installed in the second cantilever 7 along the axial direction of the second cantilever 7, and some of which are rotatably installed in the third cantilever 8 along the axial direction of the third cantilever 8; the two ends of the second transmission rod 903 are coaxially mounted with second conical teeth 904.

[0115] The fastening head 905 has a fastening groove 9051, is rotatably mounted at the end of the third cantilever 8, and has a fourth conical tooth 906 coaxially mounted at one end near the third cantilever 8;

[0116] The second transmission rod 903 is connected end to end to form an H-shaped structure, and the third conical tooth 902 is connected to the adjacent second conical tooth 904.

[0117] The upper fourth conical tooth 906 meshes with the second conical tooth 904, and the lower fourth conical tooth 906 meshes with the second conical tooth 904, while the upper fourth conical tooth 906 meshes with the second conical tooth 904, while the upper fifth conical tooth 907 meshes with the second conical tooth 904.

[0118] In this embodiment, a second motor 901 is mounted on the second cantilever 7, and a third conical tooth 902 is mounted on the second motor 901. Therefore, the second motor 901 drives the third conical tooth 902 to rotate. Simultaneously, a second transmission rod 903 is axially rotatably mounted within the second cantilever 7 and the third cantilever 8, and two ends of the second transmission rod 903 are coaxially mounted with second conical teeth 904. A fastening head 905 is mounted at the end of the third cantilever 8, and the other end of the fastening head 905 is mounted with a fourth conical tooth 906. The second conical tooth 904 meshes with the third conical tooth 902 at the second motor 901. When the second motor 901 drives the third conical tooth 902 to rotate, it drives the second transmission rod 903 to rotate, thus... The second conical teeth 904 at both ends of the second transmission rod 903 rotate, thereby causing the fourth conical teeth 906 at the fastening head 905 to rotate, so that the fastening head 905 rotates. During the disassembly process, the second cantilever 7 and the adsorption assembly 11 are controlled by the first telescopic mechanism 6 and the second telescopic mechanism 1103 to approach the arc plate to be replaced, and the fastening groove 9051 on the fastening head 905 is aligned with the bolts on the old arc plate. Under the drive of the second motor 901 and the transmission of each conical tooth, the bolts on the old arc plate are disassembled. At the same time, the fifth conical tooth 907 can reverse the fastening head 905 at the other end, so that the nut preset on the fastening head 905 at the other end locks with the bolts on the new arc plate, thus completing the installation of the new arc plate.

[0119] This invention also provides a clinometer tube, such as... Figure 13 and Figure 14 As shown, the inclinometer tube 16 provides a walking channel for the inclinometer positioning device. The inclinometer tube 16 is composed of multiple arc-shaped plates, each of which has multiple fixed cones 1601 on its outer surface. In use, the fixed cones 1601 on the outer surface of the inclinometer tube 16 are inserted into the inclined surface of the foundation pit. The inclined surface shares the weight of the pipe, ensuring its normal operation. The inclinometer tube 16 and the inclinometer positioning device are used to measure various data of the inclined surface of the foundation pit. At the same time, permanent magnets 1602 are provided at the upper and lower ends of the arc-shaped plates, and the permanent magnets 1602 are embedded in the upper and lower end faces of the arc-shaped plates. Through the magnetic attraction between the permanent magnets 1602, the arc-shaped plates are ensured to fit precisely and to be installed accurately, providing a positioning basis for subsequent replacement of the arc-shaped plates.
