Description

Technical Field

[0001] The present invention relates to the technical field of structural engineering, and in particular to an internal support structure with stress monitoring and compensation and a working method thereof. Background Art

[0002] Stress monitoring and compensation, namely stress servo adaptive support system, is a support system that combines modern mechatronics and hydraulic integration automatic control technology, computer information processing technology and visual monitoring system and other high-tech means to monitor the support axial force all day and night, and automatically or manually compensate the support axial force in a timely manner according to the parameter values ​​measured by high-precision sensors to achieve the purpose of controlling the deformation of the foundation pit. The use of the adaptive support system realizes the real-time monitoring and control of the steel support axial force, solves the harsh deformation requirements and technical problems that cannot be controlled by conventional construction methods, keeps the project in a controllable and knowable state, and has good social benefits, economic benefits and environmental protection benefits. Therefore, there is a special need for an internal support structure with stress monitoring and compensation and its working method.

[0003] The existing internal support structure with stress monitoring and compensation function has many defects. In terms of axial force compensation, it uses a hydraulic cylinder as an actuator. However, it is difficult to accurately control the slight changes in the expansion and contraction of the hydraulic cylinder with hydraulic pressure, which makes it difficult to ensure the accuracy of the compensation displacement. Moreover, this structure usually only uses a single compensation hydraulic cylinder, and its connection point is located in the middle of the end face of the steel pipe. It cannot adapt to the stress differences in all directions of the steel pipe in actual working conditions, and cannot compensate for the axial force in a targeted manner. In addition, when the geology on both sides of the foundation pit shows unilateral settlement or inconsistent settlement heights, the height of the two ends of the steel pipe inner support is unbalanced, the main body is tilted, and the connection joints produce unilateral stress or even cracks, which seriously affects the support stability. At the same time, the traditional internal support structure relies on fixed joints for connection and fixation, which is difficult to adapt to steel pipes of different sizes, has poor versatility, and lacks a quick installation mechanism when installed with other components, resulting in low efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide an internal support structure with stress monitoring and compensation and a working method thereof, so as to solve the many defects of the existing internal support structure with stress monitoring and compensation functions proposed in the above-mentioned background technology. In terms of axial force compensation, it uses a hydraulic cylinder as an actuator. However, it is difficult for the hydraulic pressure to accurately control the slight changes in the extension and contraction of the hydraulic cylinder, which makes it difficult to ensure the accuracy of the compensation displacement. Moreover, this structure usually only uses a single compensation hydraulic cylinder, and its connection point is located in the middle position of the end face of the steel pipe. It cannot adapt to the stress differences in various directions of the steel pipe in actual working conditions, and cannot compensate for the axial force in a targeted manner. In addition, when the geology on both sides of the foundation pit has unilateral settlement or inconsistent settlement heights, the height of the two ends of the steel pipe inner support is unbalanced, the main body is tilted, and the connection joints produce unilateral stress or even cracks, which seriously affect the support stability. At the same time, the traditional internal support structure relies on fixed joints for connection and fixation, which is difficult to adapt to steel pipes of different sizes, has poor versatility, and lacks a quick installation mechanism when installed with other components, resulting in low efficiency.

[0014] A working method of an internal support structure with stress monitoring and compensation, further comprising the following steps: Step 1: Fix the inner support device at the specified position, place the steel pipe in the area where the chuck can act, ensure that the position is appropriate, start the micro motor, output the rotational force to drive the bevel gear, the bevel gear engages the rotating shaft to make it rotate, the rotating shaft drives the slider to move in a straight line along the slide rail, the slider drives the connecting plate, the connecting plate drives the connecting frame, the connecting frame drives the column and the support plate, so that the chuck is close to the steel pipe to complete the fixation.

[0015] Preferably, through the quick installation mechanism, the components to be connected with the corresponding structure are brought close to the inner support section of the steel pipe so that the installation positions are roughly aligned, and the clamp of the connecting component on one side of the connecting flange is pushed to make it contact with the wedge block. The components are close, the wedge block is squeezed, and the clamp is driven to move. The clamp compresses the first spring through the connecting piece and closes to clamp the wedge block. When the clamp moves, it pushes the pin to shrink into the pin base and compresses the second spring. When the plug block of the inner support section of the steel pipe is inserted into the slot of the pin base, the pin pops out under the elastic force of the second spring, and its plug block locking groove engages with the slot to fix the plug block, thereby achieving rapid positioning and preliminary locking.

When the settlement is within a certain range, the laser light can pass through the hole in the ear plate b. When it exceeds a certain distance, the laser light is blocked by the ear plate b, the monitoring signal changes, and the DCS control system controls the alarm system to sound an alarm.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the setting of the fixed joint mechanism, when in use, the parts that need to be fixedly connected, such as steel pipes, are placed in a suitable position so that they are within the working range of the chuck, and the power of the micro motor is turned on to provide power for subsequent work. The micro motor starts and outputs rotational power to drive the bevel gear fixedly connected to it to rotate. The rotation of the bevel gear transmits power to the rotating shaft through the meshing relationship, so that the rotating shaft starts to rotate. When the rotating shaft rotates, since its outer surface is fixedly connected to the slider, the slider moves linearly along the slide rail under the drive of the rotating shaft. The movement of the slider will drive the connected connecting plate to move synchronously, and the movement of the connecting plate will drive the connecting frame to move, and the connecting frame will then drive the column and the support plate Move so that the chuck is close to the component that needs to be fixed. When the chuck contacts the component, as it continues to move, the chuck will apply clamping force to the component to fix the component. In this process, the rotating shaft allows the chuck to flexibly adjust its position and angle within a certain range, which can better adapt to components of different shapes and positions, and enhance the adaptability of the mechanism to complex working conditions. When the chuck clamps the component firmly, the micromotor can stop working. At this time, the component is stably fixed in the corresponding position, thereby improving the adaptability to components of different shapes and positions, ensuring the firmness of component fixation, and effectively preventing components from loosening and displacement when subjected to external forces, thereby ensuring the stability and safety of the working process.

[0019] 2. Through the setting of the quick installation mechanism, when in use, the parts to be connected with the corresponding structure are placed close to the inner support section of the steel pipe so that the installation positions of the two are roughly aligned. At this time, each part is in the initial state, and the first spring and the second spring are not compressed or stretched to the limit. The connecting part clamp on one side of the connecting flange is pushed to make it contact with the wedge block. As the parts get closer, the wedge block is squeezed, driving the clamp to move. The clamp compresses the first spring through the connecting piece, and at the same time the clamp begins to close, applying a clamping force to the wedge block to enhance the stability of the connection. While the clamp is moving, the bayonet is pushed to shrink into the bayonet base to compress the second spring. When the plug block set on one side surface of the inner support section of the steel pipe is inserted into the slot set on one side of the bayonet base, the bayonet pops out under the elastic force of the second spring, so that the plug block locking groove set on one side surface of the bayonet and the slot are simultaneously engaged with the fixed plug block, thereby achieving rapid positioning and preliminary locking. At this time, the wedge block is clamped by the clamp, the locking groove of the plug block on the pin engages with the plug block in the slot, and the first spring and the second spring respectively provide a certain pre-tightening force, so that the inner support section of the steel pipe is firmly connected to the component to be connected, completing the quick installation, thereby effectively shortening the time for component installation and disassembly and greatly improving work efficiency.

One side surface of the purlin 3 is fixedly connected to the base 201, one side surface of the base 201 is fixedly connected to the micro motor 202, one side surface of the micro motor 202 is fixedly connected to the bevel gear 203, one side surface of the bevel gear 203 is fixedly connected to the rotating shaft 204, the outer side surface of the rotating shaft 204 is fixedly connected to the slider 205, one side surface of the slider 205 is fixedly connected to the slide rail 206, and one side surface of the slider 205 is fixedly connected to the connecting The connecting plate 207 is fixedly connected to a connecting frame 208 on one side surface of the connecting plate 207, and a column 209 is fixedly connected to a supporting plate 210 on one side surface of the connecting frame 208, and a clamp 211 is fixedly connected to a side surface of the supporting plate 210, and a rotating shaft 212 is fixedly connected to a side surface of the clamp 211. Through the arrangement of the base 201, the micro motor 202, the bevel gear 203, the rotating shaft 204, the slider 205, the slide rail 206, the connecting plate 207, the connecting frame 208, the column 209, the supporting plate 210, the clamp 211 and the rotating shaft 212, when in use, the parts that need to be fixedly connected, such as steel pipes, are placed in a suitable position so that they are in the working position of the clamp 211. In the working range, the power supply of the micro motor 202 is turned on to provide power for subsequent work. The micro motor 202 starts and outputs rotational power to drive the bevel gear 203 fixedly connected thereto to rotate. The rotation of the bevel gear 203 transmits power to the rotating shaft 204 through the meshing relationship, so that the rotating shaft 204 starts to rotate. When the rotating shaft 204 rotates, since its outer surface is fixedly connected to the slider 205, the slider 205 moves linearly along the slide rail 206 under the drive of the rotating shaft 204. The movement of the slider 205 will drive the connecting plate 207 connected thereto to move synchronously. The movement of the connecting plate 207 drives the connecting frame 208 to move. The connecting frame 208 then drives the column 209 and the support plate 210 to move, so that the chuck 211 is close to the component that needs to be fixed. When the clamp 211 contacts the component, as it continues to move, the clamp 211 will apply a clamping force to the component to fix the component. In this process, the rotating shaft 212 can enable the clamp 211 to flexibly adjust the position and angle within a certain range, which can better adapt to components of different shapes and positions, and enhance the adaptability of the mechanism to complex working conditions. When the clamp 211 firmly clamps the component, the micro motor 202 can stop working. At this time, the component is stably fixed in the corresponding position, thereby improving the adaptability to components of different shapes and positions, ensuring the firmness of the component fixation, and effectively preventing the component from loosening and displacement when subjected to external forces, thereby ensuring the stability and safety of the working process.

[0024] Furthermore, four groups of axial force sensors 6 are symmetrically arranged around the central axis of the steel tube support section 1. The rotating shaft 204 forms a rotating structure with the micro motor 202 through the bevel gear 203. Through the setting of the bevel gear 203, when in use, the power of the micro motor 202 can be efficiently transmitted to the rotating shaft 204. The transmission of the bevel gear 203 can change the direction of power transmission, making the installation position of the motor more flexible. At the same time, it has higher transmission efficiency and carrying capacity, ensuring stable power output of the fixed section mechanism 2 during operation, and ensuring that the chuck 211 can reliably perform clamping and loosening actions.

[0025] Furthermore, the inner wall size of the bevel gear 203 is consistent with the outer wall size of the rotating shaft 204, and the slider 205 is movably connected to the slide rail 206 through the rotating shaft 204. Through the setting of the rotating shaft 204, when in use, the inner wall size of the bevel gear 203 and the outer wall size of the rotating shaft 204 are consistent, which can ensure that the two are closely matched and reduce the gap in the transmission process. During power transmission, the power loss caused by the gap can be effectively avoided, so that the bevel gear 203 can stably transmit the power of the micro motor 202 to the rotating shaft 204, thereby ensuring the smooth operation of the fixed-section mechanism 2.

[0026] Furthermore, the inner wall size of the slider 205 is consistent with the outer wall size of the slide rail 206, and the support plate 210 is symmetrically arranged in two groups with the central axis of the column 209. Through the arrangement of the slider 205 and the slide rail 206, when in use, the slider 205 has higher stability when moving on the slide rail 206. In the process of the micro motor 202 driving the slider 205 to move, due to the close fit between the two, the shaking and deviation of the slider 205 during the movement can be effectively reduced, ensuring the accuracy of the movement path of the chuck 211 when clamping the component, thereby ensuring the accuracy of the movement of the chuck 211.

[0027] Furthermore, anti-skid pads are provided on the chuck 211, and five groups of chuck 211 are symmetrically arranged with respect to the central axis of the column 209. Through the arrangement of the chuck 211, when in use, the anti-skid pads are provided on the chuck 211, which greatly increases the friction between the chuck 211 and the fixed component. When the chuck 211 clamps the component, the anti-skid pads can effectively prevent the component from sliding in the chuck 211, thereby ensuring that the component maintains a stable position during the fixing process.

[0028] Further, the quick installation mechanism 5 includes a wedge 501, a clamp 502, a connector 503, a first spring 504, a connecting flange 505, a bayonet base 506, a slot 507, a second spring 508 and a bayonet 509. The wedge 501 is fixedly connected to one side surface of the steel pipe inner support section 1, the clamp 502 is fixedly connected to one side surface of the wedge 501, the connector 503 is fixedly connected to one side surface of the clamp 502, the first spring 504 is fixedly connected to one side surface of the first spring 504, the connecting flange 505 is fixedly connected to one side surface of the connecting flange 505, and the second spring 504 is fixedly connected to one side surface of the connecting flange 505. The first spring 504 is fixedly connected to the first support section 1 of the steel pipe, and a slot 507 is arranged on one side surface of the slot base 506. A second spring 508 is fixedly connected to the inner side surface of the slot base 506. A slot 509 is fixedly connected to the inner side surface of the slot base 506. By means of the wedge block 501, the clamp 502, the connecting piece 503, the first spring 504, the connecting flange 505, the slot 507, the second spring 508 and the slot 509, when in use, the component to be connected with the corresponding structure is brought close to the inner support section 1 of the steel pipe so that the installation positions of the two are roughly aligned. At this time, each component is in the initial state, and the first spring 508 is fixedly connected to the inner support section 1 of the steel pipe. The spring 504 and the second spring 508 are not compressed or stretched to the limit, pushing the connection component clamp 502 on one side of the connection flange 505 to make it contact with the wedge 501. As the components get closer, the wedge 501 is squeezed, driving the clamp 502 to move, and the clamp 502 compresses the first spring 504 through the connecting piece 503. At the same time, the clamp 502 begins to close, applying a clamping force to the wedge 501 to enhance the stability of the connection. While the clamp 502 is moving, it pushes the bayonet 509 to shrink into the bayonet base 506, compressing the second spring 508. When the plug block set on the surface of one side of the inner support section 1 of the steel pipe is inserted The slot 507 provided on one side of the pin base 506 causes the pin 509 to pop out under the elastic force of the second spring 508, so that the plug locking groove provided on one side surface of the pin 509 and the slot 507 are simultaneously engaged with the fixed plug, thereby achieving rapid positioning and preliminary locking. At this time, the wedge block 501 is clamped by the clamp 502, and the plug locking groove on the pin 509 is engaged with the plug in the slot 507, and the first spring 504 and the second spring 508 respectively provide a certain pre-tightening force, so that the inner support section 1 of the steel pipe is firmly connected to the component to be connected, and the rapid installation is completed, thereby effectively shortening the time for component installation and disassembly, and greatly improving work efficiency.

[0029] Furthermore, a plug block that engages with the slot 507 is provided on the surface of one side of the steel tube inner support section 1, and four groups of wedge blocks 501 are symmetrically arranged around the central axis of the steel tube inner support section 1. Through the arrangement of the steel tube inner support section 1, when in use, a plug block that engages with the slot 507 is provided on one side of the steel tube inner support section 1, which can achieve precise positioning during installation, ensuring that the components to be connected are accurately docked with the steel tube inner support section 1, avoiding unstable connection or uneven structural force problems caused by installation position deviation, and improving the installation accuracy and reliability of the entire structure.

[0030] Furthermore, the steel tube inner support section 1 is connected to the clamp 502 by means of a wedge block 501, and two groups of first springs 504 are symmetrically arranged with respect to the central axis of the clamp 502. Through the arrangement of the wedge block 501 and the clamp 502, when in use, the steel tube inner support section 1 is connected to the clamp 502 by means of the wedge block 501. This connection method makes the installation process simpler and faster. During installation, it is only necessary to align the wedge block 501 with the clamp 502 and apply a certain external force to achieve a quick engagement of the two. No complicated operating steps or additional connectors 503 are required, which greatly shortens the installation time and improves work efficiency.

[0031] Furthermore, four groups of clamps 502 are symmetrically arranged around the central axis of the connecting flange 505, and a plug locking groove is arranged on one side surface of the latch 509. Through the arrangement of the clamps 502, when in use, four groups of clamps 502 are symmetrically arranged around the central axis of the connecting flange 505. Such a layout can provide a more uniform distribution of clamping force. During use, four groups of clamps 502 simultaneously apply clamping force to the wedge 501 or other clamped objects, which can better resist external loads and vibrations compared to a smaller number of clamps 502, and avoid loose connections caused by insufficient local clamping force.

[0032] Furthermore, a rubber pad is provided at the end of the pin 509, and the pin 509 forms a telescopic structure with the pin base 506 through the second spring 508. Through the setting of the pin 509, when in use, the pin 509 forms a telescopic structure with the pin base 506 through the second spring 508, so that the pin 509 has an automatic telescopic function. During the installation process, when the pin 509 contacts other components and is subjected to external force, the pin 509 can compress the second spring 508 and automatically retract into the pin base 506. When the external force disappears, the pin 509 will automatically pop out under the elastic force of the second spring 508, thereby realizing automatic positioning and locking of the pin 509, thereby improving the convenience and efficiency of installation. Example

[0033] A working method of an internal support structure with stress monitoring and compensation, using an internal support structure with stress monitoring and compensation in Example 1, further comprising the following steps: Step 1: Fix the inner support device at the specified position, place the steel pipe in the area where the chuck 211 can act, ensure that the position is appropriate, start the micro motor 202, output the rotation force to drive the bevel gear 203, the bevel gear 203 engages the rotating shaft 204 to make it rotate, the rotating shaft 204 drives the slider 205 to move linearly along the slide rail 206, the slider 205 drives the connecting plate 207, the connecting plate 207 drives the connecting frame 208, the connecting frame 208 drives the column 209 and the support plate 210, so that the chuck 211 is close to the steel pipe to complete the fixation.

[0034] Step 2: Through the quick installation mechanism 5, the components to be connected with the corresponding structure are brought close to the steel pipe inner support section 1 so that the installation positions are roughly aligned, and the clamp 502 of the connecting component on one side of the connecting flange 505 is pushed to make it contact with the wedge block 501. The components are close, and the wedge block 501 is squeezed, driving the clamp 502 to move. The clamp 502 compresses the first spring 504 through the connecting piece 503 and closes, clamping the wedge block 501. When the clamp 502 moves, it pushes the pin 509 to shrink into the pin base 506 and compresses the second spring 508. When the plug of the steel pipe inner support section 1 is inserted into the slot 507 of the pin base 506, the pin 509 pops out under the elastic force of the second spring 508, and its plug locking groove is engaged with the slot 507 to fix the plug, thereby realizing rapid positioning and preliminary locking.

[0035] Step 3: Start equipment preparation work, monitor the axial force of the steel pipe support through the axial stress monitoring system, and four axial force sensors 6 are installed on the upper, lower, left and right outer walls of the steel pipe to monitor the axial stress and transmit the signal to the DCS control system. The DCS control system controls the extension and retraction of the corresponding telescopic compensation device in the axial force compensation section according to the received axial force signal and the stress size. The end of the device is connected by a ball joint and works independently. The upper and lower devices are controlled by the upper and lower axial force sensors 6 respectively to achieve precise compensation.

[0036] Step 4: When settlement occurs on one side of the foundation pit, the guide wheel 21 between the ear plate a 22 and the ear plate b 23 slides on the guide rail 20, and the mounting plates a 18 and b 19 can move up and down to achieve settlement compensation adaptation, prevent the two ends of the support inside the steel pipe from tilting, and ensure the stability of the support. When the settlement is within a certain range, the laser light can pass through the hole of the ear plate b 23. When it exceeds a certain distance, the laser light is blocked by the ear plate b 23, the monitoring signal changes, and the DCS control system controls the alarm system to sound an alarm.

[0037] Working principle: This internal support structure with stress monitoring and compensation and its working method, through the setting of the fixed joint mechanism 2, when in use, the parts that need to be fixedly connected, such as steel pipes, are placed in a suitable position so that they are within the working range of the chuck 211, and the power of the micro motor 202 is turned on to provide power for subsequent work. The micro motor 202 starts and outputs rotational power to drive the bevel gear 203 fixedly connected to it to rotate. The rotation of the bevel gear 203 transmits power to the rotating shaft 204 through the meshing relationship, so that the rotating shaft 204 starts to rotate. When the rotating shaft 204 rotates, since its outer surface is fixedly connected to the slider 205, the slider 205 is driven by the rotating shaft 204 to make a linear motion along the slide rail 206, and the movement of the slider 205 will bring The connecting plate 207 connected thereto moves synchronously, and the movement of the connecting plate 207 drives the connecting frame 208 to move, and the connecting frame 208 further drives the column 209 and the support plate 210 to move, so that the clamp 211 is close to the component that needs to be fixed. When the clamp 211 contacts the component, as it continues to move, the clamp 211 will apply a clamping force to the component to fix the component. In this process, the rotating shaft 212 can enable the clamp 211 to flexibly adjust the position and angle within a certain range, which can better adapt to components of different shapes and positions, and enhance the adaptability of the mechanism to complex working conditions. When the clamp 211 firmly clamps the component, the micro motor 202 can stop working. At this time, the component is stably fixed in the corresponding position, thereby improving the The adaptability of the components ensures the firmness of the components. When subjected to external forces, it can effectively prevent the components from loosening and displacement, ensuring the stability and safety of the working process. Through the setting of the quick installation mechanism 5, when in use, the components to be connected with the corresponding structure are placed close to the inner support section 1 of the steel pipe, so that the installation positions of the two are roughly aligned. At this time, each component is in the initial state, and the first spring 504 and the second spring 508 are not compressed or stretched to the limit, pushing the connecting component clamp 502 on one side of the connecting flange 505 to make it contact with the wedge block 501. As the components get closer, the wedge block 501 is squeezed, driving the clamp 502 to move, and the clamp 502 compresses the first spring 504 through the connecting member 503. At the same time, the clamp 502 begins to close, pressing the wedge block 501. 01 applies clamping force to enhance the stability of the connection. While the clamp 502 is in motion, the bayonet 509 is pushed to retract into the bayonet base 506, compressing the second spring 508. When the plug block provided on one side surface of the steel pipe inner support section 1 is inserted into the slot 507 provided on one side of the bayonet base 506, the bayonet 509 pops out under the elastic force of the second spring 508, so that the plug block locking groove provided on one side surface of the bayonet 509 and the slot 507 are simultaneously engaged with the fixed plug block, thereby realizing rapid positioning and preliminary locking. At this time, the wedge block 501 is clamped by the clamp 502, and the plug block locking groove on the bayonet 509 is engaged with the slot 507. The first spring 504 and the second spring 508 respectively provide a certain pre-tightening force, so that the steel pipe inner support section 1 is firmly connected to the component to be connected.The device can complete quick installation, thereby effectively shortening the time of component installation and disassembly, and greatly improving work efficiency. The device uses the synergistic effect of the fixed joint mechanism 2 and the quick installation mechanism 5. During installation, the quick installation mechanism 5 realizes quick docking, and the fixed joint mechanism 2 quickly completes the fixation. The cooperation between the two greatly improves the installation efficiency and simplifies the installation process. In terms of stability, the fixed joint mechanism 2 is reliably fixed, and the quick installation mechanism 5 provides a tightening effect, which synergistically enhances the structural stability, improves safety performance, and reduces safety accidents. In terms of maintenance, it is convenient to disassemble and replace components, shorten maintenance time, reduce costs, reduce component wear, and extend service life. In addition, they can adapt to different working conditions, flexibly connect with a variety of components, have strong compatibility, and high versatility. The model of the micro motor 202 is WL-37RS528, and the model of the servo motor is YE2-132S-4.
