Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of steel structure construction, and particularly to a real-time monitoring mechanism for high-altitude sliding of long-span steel structures based on multi-sensor fusion. Background Art
[0002] The high-altitude sliding method refers to a construction method in which a structure is divided into several strip-shaped or block-shaped units. After assembly is completed on the ground or a high-altitude platform, it is slid along a track to the final designed position through a hydraulic jacking system or a traction device, and then the overall assembly is formed. In related technologies, in order to achieve the effect of simplifying the sliding construction of long-span steel structures, for example, the patent document with the publication number CN104863374B in the prior art discloses a long-span steel structure sliding mechanism and its sliding method. This sliding mechanism embeds track embedments in a reinforced concrete beam, and lays two first I-beams on the track embedments as two tracks. When fabricating the sliding shoe support, a lateral baffle is welded to the bottom of the second lower flange of the second I-beam, and two gusset plates are welded to the second upper flange as clamping members for the steel structure. The front end of the second lower flange of the second I-beam is bent upward to form a bending part; then the steel structure is placed at the clamping members on the sliding shoe support, and the clamping members clamp the steel structure; finally, a winch is used in cooperation with a lifting gantry to translate and lift the steel structure, thereby completing the sliding installation of the long-span steel structure.
[0003] Although the above-mentioned prior art solutions can achieve the effect of facilitating on-site fabrication by setting tracks and sliding shoe supports made of optional H-shaped steel, and the operation of sliding long-span steel structures using the sliding mechanism is simple, so as to improve work efficiency and economic benefits; however, during the sliding and lifting processes, it is impossible to monitor the mid-span bending condition of the long-span steel structure. If the mid-span bending degree of the long-span steel structure fails to meet the safety requirements, structural plastic deformation or even fracture may occur during subsequent sliding and lifting processes, posing a relatively large safety hazard; moreover, although real-time monitoring technologies for high-altitude sliding of long-span steel structures based on multi-sensor fusion have emerged in the market, for long-span steel structures that do not meet the safety requirements, they cannot be protected in time when damaged, especially during the lifting process, there will be a greater safety hazard at high altitude.
[0004] In view of this, we propose a real-time monitoring mechanism for high-altitude sliding of long-span steel structures based on multi-sensor fusion. Summary of the Invention

When the support plate member 3 is driven by the driving component 4 to slide downward away from the bottom of the steel structure, and after the driving component 4 drives the support plate member 3 to slide down, it continues to drive it to rotate to one side of the detection component 2, so that the detection component 2 is automatically rotated to the bottom of the steel structure by an external force for bending degree detection, the state of the support plate member 3 is defined as the second state.

An auxiliary plate 24 is arranged outside the support rod 21. The auxiliary plate 24 is axially assembled outside the support rod 21. An elastic member 25 is arranged between the auxiliary plate 24 and the connecting plate 22. Both ends of the elastic member 25 are snap-connected to the auxiliary plate 24 and the connecting plate 22 respectively, so that the elastic member 25 generates a torsional force to rotate the support rod 21 upward, thereby driving the sensing assembly 23 outside the support rod 21 to rotate to the bottom of the steel structure.

[0029] Connecting blocks 31 are arranged at both ends of the support plate member 3. Sliding members 32 are fixedly arranged on the sides of the connecting blocks 31 at both ends away from each other; the driving assembly 4 includes a housing 41, a first sliding hole 42 and a second sliding hole 43. The housing 41 is fixedly arranged outside the sliding support 1; the first sliding hole 42 is opened on the inner side of the housing 41.

After the sliding member 32 loses support, it automatically slides down by relying on the gravity of the support plate member 3 and rotates along the second sliding hole 43. Wherein, an anti-disengagement block 34 is fixedly arranged on the side of the sliding member 32 away from the connecting block 31 to prevent the sliding member 32 from disengaging from the housing 41.
[0030] Among them, the first sliding hole 42 is a vertical sliding hole formed in the housing 41, and the sliding member 32 slides vertically in the first sliding hole 42; the second sliding hole 43 is an arc-shaped hole provided at the bottom end of the first sliding hole 42, and when the sliding member 32 slides to the second sliding hole 43, it can rotate along the second sliding hole 43.
[0031] The driving assembly 4 further includes a bushing 44. The bushing 44 is fixedly arranged inside the housing 41. The bushing 44 is located at the bottom of the sliding member 32 and is used to support the sliding member 32 after it slides down. The sliding member 32 is provided with a mating groove 321 corresponding to the bushing 44. A third rolling body 442 is rotatably arranged on the circumferential side of the bushing 44 corresponding to the mating groove 321. The bushing 44 is fixedly arranged inside the housing 41 through an outer fixing plate 441; at both corners of the top of the sliding member 32, second rolling bodies 35 are rotatably arranged, and the second rolling bodies 35 are in contact with the inner side of the second sliding hole 43 to ensure the smoothness of the sliding member 32 during rotation.
[0032] The driving assembly 4 further includes a rotating shaft 45 and an eccentric wheel 46. The rotating shaft 45 is rotatably arranged inside the bushing 44; the eccentric wheel 46 is fixedly arranged on the outer side of the rotating shaft 45 and is used to support the vertical sliding of the sliding member 32 and to drive the sliding member 32 to slide along the second sliding hole 43 and the bushing 44; among them, the rotating shaft 45 is driven by an external force to drive the eccentric wheel 46 to rotate, and a first rolling body 33 is arranged on the outer side of the sliding member 32, and the first rolling body 33 is in contact with the outer side of the eccentric wheel 46.
[0033] Specifically, a bearing plate 47 is rotatably arranged on the outer side of the rotating shaft 45. The bearing plate 47 is fixedly arranged inside the housing 41. A gear 48 is coaxially and fixedly arranged on the outer side of the rotating shaft 45 on the side of the bearing plate 47 away from the eccentric wheel 46. A toothed plate 49 is engaged with the bottom of the gear 48. The toothed plate 49 is slidably arranged on the top of the slide rail 411. The slide rail 411 is fixedly arranged inside the housing 41. A third linear member 410 for driving the toothed plate 49 to slide is fixedly arranged on the outer side of the housing 41.
[0034] The sliding support 1 includes a box body 11, a mounting plate 13, a top plate 14 and a support roller 16. The box body 11 is fixedly arranged on the outer side of the housing 41, and the box body 11 is slidably installed with the sliding track; the mounting plate 13 is fixedly arranged on the outer side of the box body 11 and is used to install a detector for detecting the position and angle of the end of the steel structure; the top plate 14 is fixedly arranged on the tops of the box body 11 and the housing 41, and a through hole 15 is formed inside the top plate 14; the support roller 16 is rotatably arranged corresponding to the through hole 15 inside the box body 11 and is driven by an external force to rotate and lift.
[0035] The sliding support 1 further includes an adjusting roller 17. The adjusting roller 17 is arranged corresponding to the through hole 15 and is arranged at an interval from the support roller 16. The adjusting rollers 17 are symmetrically arranged on both sides of the steel structure, and the adjusting rollers 17 on both sides are driven by an external force to slide; the sliding support 1 is driven by an external force to drive the long-span steel structure to move upward.
[0036] Specifically, a mounting seat 12 is fixedly arranged at the bottom of the box body 11 for installing a sliding component and assembling it with a sliding track. Bearing seats 161 are rotatably arranged at both ends of the support roller 16. The bearing seats 161 are slidably arranged on both sides of the box body 11, and linear components one 162 are arranged at the bottoms of the bearing seats 161. The linear components one 162 are fixedly arranged on the outer side of the box body 11 for driving the support roller 16 to move up and down. After the steel structure on the top of the top plate 14 is lifted, the support roller 16 is driven to rotate by the motor 163, so that both ends of the steel structure are symmetrically placed on the top of the top plate 14 for support, ensuring uniform force on the steel structure during the sliding process. The motor 163 is fixedly arranged on the outer side of one of the bearing seats 161; a side plate 172 is rotatably arranged at the top end of the adjusting roller 17, and a sliding seat 171 is rotatably arranged at the bottom end. The sliding seat 171 is fixedly connected with the side plate 172. The sliding seat 171 slides along the sliding table 18 and is arranged inside the box body 11. A linear component two 173 for driving the sliding seat 171 to slide is fixedly arranged on the outer side of the box body 11. A detection instrument capable of detecting the position and angle of the end of the steel structure can be installed on the outer side of the box body 11 through the mounting plate 13, so as to control the support roller 16 and the adjusting roller 17 to rotate and clamp respectively before sliding to perform translation and deviation correction adjustment on the steel structure through the detection structure.
[0037] In the above technical solution, the linear component one 162, the linear component two 173, and the linear component three 410 are power components with a linear output function. In the technical solution of this application, considering that the working object is a large-span steel structure with a large mass, the linear component one 162, the linear component two 173, and the linear component three 410 are all selected as hydraulic push rods with a large and stable thrust.
[0038] Principle and advantages of the real-time monitoring mechanism for high-altitude sliding of large-span steel structures based on multi-sensor fusion: First, connect the sliding support 1 to the sliding component in advance through the mounting base 12, and slide the sliding support 1 on the sliding track through the sliding component. Then, connect the support plate member 3 between the two sliding supports 1 through the connecting block 31. At this time, the support plate member 3 is in a horizontal state and can support the long-span steel structure, so as to facilitate the hoisting or on-site assembly of the long-span steel structure. After the steel structure is placed on the top of the sliding support 1, install the corresponding detector through the mounting plate 13 on the outside of the box body 11 to make the detector detect the end of the steel structure; during the actual construction process, it is easy for the steel structure to deviate when placed on the top of the sliding support 1. At this time, the linear member 162 can be used to drive the bearing seat 161 to slide upward on both sides of the box body 11, so that the bearing seat 161 drives the support roller 16 to move inward toward the through hole 15, and lift both ends of the steel structure. The motor 163 is used to drive the support roller 16 to rotate to drive the steel structure to move along the length direction, so as to symmetrically arrange both ends of the steel structure on the top of the two sliding supports 1. At the same time, the linear member 173 is used to drive the sliding seat 171 to slide along the sliding table 18, so that the sliding seat 171 drives the adjusting roller 17 to clamp both sides of the steel structure, so as to straighten the steel structure. After the steel structure is adjusted, the support roller 16 and the adjusting roller 17 are reset, and the top plate 14 and the support plate member 3 support the steel structure. When starting to slide, drive the support plate member 3 to move downward away from the bottom of the steel structure through the driving assembly 4 to make room for the subsequent rotational movement. Then, under the drive of the driving assembly 4, the support plate member 3 continues to rotate, so that the support plate member 3 releases the extrusion of the sensing assembly 23, and the sensing assembly 23 automatically rotates to the bottom of the steel structure and contacts the bottom of the steel structure for bending detection; during the sliding process, if the long-span steel structure undergoes bending deformation, the sensing assembly 23 at the bottom will be subjected to pressure and detect the pressure condition. According to the detection positions of several sensing assemblies 23, the bending condition of the long-span steel structure during the sliding process can be monitored in real time. If the bending condition of the steel structure exceeds the limit, the sliding can be stopped in time. If the bending is excessive during the lifting and sliding process, at this time, the driving assembly 4 can be used to drive the support plate member 3 to automatically reset to the bottom of the steel structure and support the steel structure at a high altitude in time, preventing the steel structure from being damaged or even broken and falling when undergoing plastic deformation, ensuring the safety of the long-span steel structure during the high-altitude sliding process.
[0039] Its advantages are as follows. By setting the sliding support 1 to support the steel structure, it is ensured that the steel structure can slide. Before sliding, the two ends of the steel structure are detected by the detector outside the sliding support 1, and the steel structure is adjusted in time according to the detection results to ensure the accuracy of monitoring during the sliding process of the steel structure. And by setting the support plate member 3 to support the steel structure during loading, it is convenient for the hoisting or on-site assembly of the steel structure. During sliding, the support plate member 3 can be retracted under the drive of the drive assembly 4, so that the support plate member 3 automatically gives way. At this time, the detection assembly 2 automatically moves to the bottom of the steel structure for bending detection, which is convenient for the assembly of the detection assembly 2 and the steel structure. By setting the drive assembly 4 to drive the support plate member 3 to operate automatically, during the upward sliding process, when the steel structure is bent excessively, the support plate member 3 can be driven to move to the bottom of the steel structure in time to support it, preventing the steel structure from being bent and damaged or disconnected. By setting the detection assembly 2 to detect the bending of the steel structure during sliding, potential accidents can be pre-warned in advance before the installation of the steel structure, and the emergency plan can be started in time to avoid plastic deformation before the structure is installed.
[0040] When the support plate member 3 of the real-time monitoring mechanism for high-altitude sliding of long-span steel structures based on multi-sensor fusion in this application supports the steel structure, the support plate member 3 is in a horizontal state under the drive of the drive assembly 4, so as to facilitate the hoisting or assembly of the long-span steel structure before sliding. During sliding, the linear part three 410 drives the toothed plate 49 to slide along the slide rail 411, so that the toothed plate 49 drives the gear 48 to rotate. The gear 48 drives the eccentric wheel 46 to rotate through the rotating shaft 45. At this time, the top of the eccentric wheel 46 gradually deviates and reduces the support height for the first rolling body 33, so that the sliding part 32 begins to slide downward under the influence of the gravity of the support plate member 3. When the mating groove 321 at the bottom of the sliding part 32 is mated with the outside of the bushing 44, the support plate member 3 moves away from the bottom of the steel structure. Subsequently, the sliding part 32 continues to slide along the inner side of the second sliding hole 43, so that the sliding part 32 drives the support plate member 3 to rotate by a certain angle around the rotating shaft 45, so that the support plate member 3 automatically vacates the detection space at the bottom of the steel structure, so as to facilitate the detection assembly 2 to move to the bottom of the steel structure for bending detection; Further, in order to enable the support plate member 3 to quickly respond to rotation, when the slider 32 moves to the top of the bushing 44 and continues to drive the rotation of the eccentric wheel 46, the eccentric wheel 46 pushes the first rolling body 33 to move towards the side where the second sliding hole 43 is located, thereby driving the slider 32 to slide between the second sliding hole 43 and the bushing 44. To ensure the stability of the sliding, the second rolling body 35 and the third rolling body 442 are respectively arranged at the two top corners of the slider 32 and the outer side of the bushing 44; when ascending and sliding, the steel structure may be deformed due to vibration. If deformation occurs, it indicates that the stability of the steel structure is unqualified. Once deformation occurs, according to the detection information of the detection component 2, the linear member three 410 can be controlled to operate in a timely manner, so that the linear member three 410 drives the eccentric wheel 46 to rotate reversely around the rotating shaft 45. As the support radius of the eccentric wheel 46 gradually increases, the first rolling body 33 is gradually lifted upward. Since the slider 32 is limited by the second sliding hole 43, the slider 32 drives the support plate member 3 to rotate under the guidance of the second sliding hole 43. At this time, the support plate member 3 begins to squeeze the sensing component 23 to rotate to one side, so that the detection end of the sensing component 23 is far away from the bottom of the steel structure. When the support plate member 3 rotates to the horizontal state, as the eccentric wheel 46 continues to rotate and push the first rolling body 33 upward, the support plate member 3 is driven by the slider 32 to approach and fit against the bottom of the steel structure.
[0041] It should be noted that the above support method has the following advantages: Advantage 1: By arranging the first sliding hole 42 inside the housing 41 to vertically limit the slider 32, the slider 32 can drive the support plate member 3 to move up and down at the bottom of the steel structure, so as to automatically make way before rotating and storing the support plate member 3. And after the slider 32 moves down a certain distance, the slider 32 automatically slides towards the inside of the second sliding hole 43 under the influence of the gravity of the support plate member 3, so as to facilitate the storage of the support plate member 3; specifically, the vertical center line of the slider 32 and the second sliding hole 43 are on the same side of the longitudinal diameter of the bushing 44.
[0042] Advantage 2: By arranging the slider 32 to drive the support plate member 3 to move, and by arranging the first sliding hole 42 to limit the slider 32, the stability of the support plate member 3 in the horizontal state is ensured. When the slider 32 descends to the outside of the bushing 44, the slider 32 automatically rotates by relying on the gravity of the support plate member 3, ensuring the stability of the support plate member 3 during the storage and support processes.
[0043] Advantage three: By setting the eccentric wheel 46 to cooperate with the first rolling element 33 to drive the sliding member 32 to move in the first sliding hole 42 and the second sliding hole 43. When the support plate member 3 supports the steel structure, the eccentric wheel 46 pushes the first rolling element 33 to drive the sliding member 32 to slide along the second sliding hole 43. And when the sliding member 32 slides to the top of the bushing 44, the eccentric wheel 46 continues to push the sliding member 32 to the highest position, realizing the vertical sliding of the sliding member 32, so as to drive the support plate member 3 to be adjusted from the storage state to the support working state.
[0044] Advantage four: By setting the eccentric wheel 46 to support the sliding member 32, when storing the support plate member 3, the support height can be gradually reduced by rotating the eccentric wheel 46. And when the lowest support point of the eccentric wheel 46 passes over the first rolling element 33, the eccentric wheel 46 continues to rotate to make way for the rotation of the first rolling element 33, and the sliding of the sliding member 32 is buffered by the support of the first rolling element 33, preventing the sliding member 32 from colliding with the second sliding hole 43 after the sliding stops under the influence of the gravity of the support plate member 3 (due to the large mass of the support plate member 3, it will cause the sliding member 32 to slide quickly and collide with the second sliding hole 43).
