Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel structure construction, in particular to a long-span steel structure high-altitude sliding real-time monitoring mechanism based on multi-sensor fusion. BACKGROUND

[0002] High-altitude sliding method refers to a construction method that divides the structure into several strip or block units, assembles on the ground or high-altitude platform, and then slides to the final design position along the track through the hydraulic jacking system or traction device, and then performs overall assembly to form. In the related art, in order to achieve the effect of simplifying the sliding construction of long-span steel structure, for example, the patent document with the publication number CN104863374B discloses a long-span steel structure sliding mechanism and a sliding method thereof, which pre-buries track embedment on the reinforced concrete beam, and lays two first I-beams on the track embedment as two tracks, places the prepared sliding shoe bracket on the track, and when the sliding shoe bracket is prepared, a lateral baffle is welded at the bottom of the second lower flange of the second I-beam, and two rib plates are welded on the second upper flange as clamping pieces for clamping the steel structure, and the front end of the second lower flange of the second I-beam is bent upward to form a bent portion; then the steel structure is placed on the clamping pieces on the sliding shoe bracket, and the clamping pieces are clamped on the steel structure; finally, the steel structure is translated and lifted by the winch and the lifting gantry, thereby completing the sliding installation of the long-span steel structure.

[0003] The above-mentioned prior art scheme can realize convenient construction site preparation and simple operation of the sliding mechanism for sliding the long-span steel structure, thereby improving work efficiency and economic benefits; however, the cross-mid bending of the long-span steel structure cannot be monitored during the sliding and lifting process, and if the cross-mid bending of the long-span steel structure cannot meet the safety requirements, plastic deformation or even fracture of the structure may occur during the subsequent sliding and lifting process, which poses a great safety hazard; moreover, although multi-sensor fusion-based long-span steel structure high-altitude sliding real-time monitoring technology has appeared in the market, for long-span steel structures that do not meet safety requirements, timely safety protection cannot be provided when they are damaged, especially during the lifting process, which poses a greater safety hazard at high altitudes.

[0004] In view of this, we propose a long-span steel structure high-altitude sliding real-time monitoring mechanism based on multi-sensor fusion. SUMMARY

[0075] The principle and advantages of the multi-sensor fusion-based real-time monitoring mechanism for high-altitude sliding of large-span steel structures are as follows:

[0076] Firstly, the sliding support 1 is connected with the sliding component in advance through the mounting seat 12, the sliding support 1 is slidingly assembled on the sliding rail through the sliding component, then the support plate 3 is connected between the two sliding supports 1 through the connecting block 31, at this time, the support plate 3 is in a horizontal state, the large-span steel structure can be supported, so that the large-span steel structure is hoisted or assembled on site, after the steel structure is placed on the top of the sliding support 1, the corresponding detector is installed through the mounting plate 13 outside the box body 11, so that the detector detects the end of the steel structure; in the actual construction process, the steel structure placed on the top of the sliding support 1 is easy to deviate, at this time, the bearing seat 161 is driven by the linear part one 162 to slide upwards on both sides of the box body 11, the bearing seat 161 drives the supporting roller 16 to move to the inside of the through hole 15, and the both ends of the steel structure are lifted, the supporting roller 16 is driven to rotate by the motor 163, the steel structure is driven to move along the length direction, so that the both ends of the steel structure are symmetrically arranged on the top of the two sliding supports 1, at the same time, the sliding seat 171 is driven to slide along the sliding table 18 by the linear part two 173, the adjusting roller 17 is driven to clamp to both sides of the steel structure by the sliding seat 171, so as to straighten the steel structure, after the steel structure is adjusted, the supporting roller 16 and the adjusting roller 17 are reset, the top plate 14 and the support plate 3 support the steel structure;

[0077] When starting to slide, the support plate 3 is driven by the driving assembly 4 to move downwards away from the bottom of the steel structure, leaving space for subsequent rotating movement, then the support plate 3 continues to rotate under the driving of the driving assembly 4, the support plate 3 releases the extrusion on the sensing assembly 23, the sensing assembly 23 automatically rotates to the bottom of the steel structure and contacts the bottom of the steel structure to detect bending; during the sliding process, if the large-span steel structure is bent and deformed, the sensing assembly 23 at the bottom will be subjected to pressure and detect the pressure condition, then according to the detection positions of the sensing assemblies 23, the bending condition of the large-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, the support plate 3 can be automatically reset to the bottom of the steel structure by the driving assembly 4 at this time, the steel structure is supported in time in the air, so as to prevent the steel structure from being damaged or even falling off when plastic deformation occurs, and the safety of the large-span steel structure during the high-altitude sliding process is ensured.

[0078] The advantages are that the steel structure is supported by the sliding support 1 to ensure that the steel structure can slide, and the two ends of the steel structure are detected by the detector outside the sliding support 1 before sliding, and the steel structure is adjusted in time according to the detection result to ensure the accuracy of the monitoring during the sliding of the steel structure; and the support plate 3 is arranged to support the steel structure during loading, which facilitates hoisting or on-site assembly of the steel structure, and the support plate 3 can be stored under the driving of the driving assembly 4 during sliding, so that the support plate 3 automatically gives way, and at this time the detection assembly 2 automatically moves to the bottom of the steel structure for bending detection, which facilitates the assembly of the detection assembly 2 and the steel structure; the driving assembly 4 is arranged to drive the support plate 3 to automatically operate, so that when the steel structure is excessively bent during the upward sliding process, the support plate 3 can be driven to move to the bottom of the steel structure in time for support, preventing the steel structure from being bent and damaged or disconnected; the detection assembly 2 is arranged to detect the bending of the steel structure during the sliding process, which can early warn potential accidents before the steel structure is installed, start the emergency plan in time, and avoid plastic deformation before the structure is installed.

[0079] In the application, the support plate 3 in the multi-sensor fusion real-time monitoring mechanism for high-altitude sliding of a large-span steel structure is supported by the driving assembly 4 in a horizontal state, so as to facilitate hoisting or assembly of the large-span steel structure before sliding, and during sliding, the linear member three 410 drives the gear plate 49 to slide along the slide rail 411, the gear plate 49 drives the gear 48 to rotate, the gear 48 drives the eccentric wheel 46 to rotate through the rotating shaft 45, the top of the eccentric wheel 46 gradually deviates to reduce the support height of the rolling body one 33, the sliding member 32 starts to slide downward under the influence of the gravity of the support plate 3, when the matching groove 321 at the bottom of the sliding member 32 matches the outside of the shaft sleeve 44, the support plate 3 is away from the bottom of the steel structure, and then the sliding member 32 continues to slide along the inside of the second sliding hole 43, so that the sliding member 32 drives the support plate 3 to rotate around the rotating shaft 45 by a certain angle, the support plate 3 automatically releases the detection space at the bottom of the steel structure, so as to facilitate the movement of the detection assembly 2 to the bottom of the steel structure for bending detection;

[0080] Further, in order to enable the support plate 3 to respond quickly to rotation, when the sliding member 32 moves to the top of the shaft sleeve 44, continue to drive the eccentric wheel 46 to rotate, make the eccentric wheel 46 push the rolling body one 33 to move to the side where the second sliding hole 43 is located, and then drive the sliding member 32 to slide between the second sliding hole 43 and the shaft sleeve 44, in order to ensure the stability of sliding, the rolling body two 35 and the rolling body three 442 are arranged at the top of the two corners of the sliding member 32 and the outer side of the shaft sleeve 44 respectively; when ascending sliding is performed, the steel structure may be affected by vibration and deformed, if deformation occurs, it indicates that the stability of the steel structure is unqualified, and once deformation occurs, the linear member three 410 can be controlled to operate in time according to the detection information of the detection assembly 2, so that the linear member three 410 drives the eccentric wheel 46 to rotate reversely around the rotating shaft 45, with the support radius of the eccentric wheel 46 gradually increasing, the rolling body one 33 is gradually lifted upward, and since the sliding member 32 is limited by the second sliding hole 43, the sliding member 32 drives the support plate 3 to rotate under the guidance of the second sliding hole 43, at this time, the support plate 3 starts to press the sensing assembly 23 to one side, so that the detection end of the sensing assembly 23 moves away from the bottom of the steel structure, when the support plate 3 rotates to the horizontal state, the rolling body one 33 is continuously lifted by the rotation of the eccentric wheel 46, and then the support plate 3 is driven by the sliding member 32 to approach and fit to the bottom of the steel structure.

[0081] It is worth noting that the above support mode has the following advantages:

[0082] Advantage one, by arranging the first sliding hole 42 on the inner side of the shell 41 to vertically limit the sliding member 32, the sliding member 32 can drive the support plate 3 to move up and down at the bottom of the steel structure, so as to automatically make room before rotating to store the support plate 3, and after the sliding member 32 moves downward by a certain distance, the sliding member 32 automatically slides to the inner side of the second sliding hole 43 under the influence of the gravity of the support plate 3, so as to store the support plate 3; specifically, the vertical center line of the sliding member 32 and the second sliding hole 43 are located on the same side of the longitudinal diameter of the shaft sleeve 44.

[0083] Advantage two, by arranging the sliding member 32 to drive the support plate 3 to move, and by arranging the first sliding hole 42 to limit the sliding member 32, the stability of the support plate 3 in the horizontal state is ensured, when the sliding member 32 descends to the outer side of the shaft sleeve 44, the sliding member 32 automatically rotates under the gravity of the support plate 3, ensuring the stability during storage and support of the support plate 3.

[0084] The third advantage is that the eccentric wheel 46 is arranged to drive the rolling body I 33 to drive the sliding piece 32 to move in the first sliding hole 42 and the second sliding hole 43. When the support plate 3 supports the steel structure, the eccentric wheel 46 drives the rolling body I 33 to drive the sliding piece 32 to slide along the second sliding hole 43. When the sliding piece 32 slides to the top of the shaft sleeve 44, the eccentric wheel 46 continues to drive the sliding piece 32 to the highest position, thereby driving the sliding piece 32 to slide vertically, so as to drive the support plate 3 to adjust from the storage state to the support working state.

[0085] The fourth advantage is that the eccentric wheel 46 is arranged to support the sliding piece 32. When the support plate 3 is stored, the support height is gradually reduced by rotating the eccentric wheel 46. When the lowest support point of the eccentric wheel 46 is higher than the rolling body I 33, the rotation of the eccentric wheel 46 is continued to make room for the rotation of the rolling body I 33. The rolling body I 33 supports the sliding piece 32 to buffer the sliding of the sliding piece 32, so as to prevent the sliding piece 32 from being stopped by the gravity of the support plate 3 and colliding with the second sliding hole 43 (because the mass of the support plate 3 is large, the sliding piece 32 will slide quickly and collide with the second sliding hole 43).
