Description

Technical Field

[0001] The invention relates to the technical field of sliding supports, and in particular to a steel structure sliding support for civil engineering. Background Art

[0002] Steel structure sliding bearing is a connection element widely used in civil engineering. It is mainly used to allow a certain degree of horizontal sliding when the structure is stressed to achieve elastic deformation and energy dissipation of the structure. This kind of bearing is usually composed of friction material and sliding surface. Through its unique structural design and material selection, it can meet the needs of various complex engineering environments.

[0003] After searching, the Chinese patent number CN218176212U discloses a steel structure sliding support for civil engineering, which relates to the technical field of sliding supports. This patent includes: a base, on which a ground nail is provided, connected to the ground; a mobile box, which is fixedly installed on the top of the base, and a support column is movably installed at the bottom of the inner wall of the mobile box, and the support column passes through the mobile box and extends to the outside; a shock-absorbing assembly, the number of which is two. This patent is that when the support column vibrates, it is displaced, pushing the shock-absorbing plate, and the shock-absorbing plate pushes the two connecting plates to gradually fold, thereby driving the two sliding plates to squeeze the shock-absorbing spring. The rebound force generated by the squeezed shock-absorbing spring has a certain shock-absorbing and buffering effect on the vibration of the support column, avoiding large displacement of the support column, resulting in damage to the connection point of the steel structure, affecting its service life, and at the same time, the two shock-absorbing assemblies can have a better shock-absorbing effect on the support column. The Chinese patent number CN218176212U solves the problem that the existing sliding bearing has a certain buffer structure inside, which can have a certain shock-absorbing effect when the steel structure support column vibrates, but the existing buffer structure has a poor shock-absorbing effect and can only provide a small degree of shock-absorbing for the subsequent support column. When the support column shakes greatly, the buffering effect is poor and it is inconvenient to use.

[0004] However, in actual use, it is difficult to effectively limit the support column, that is, it is difficult to make the support and the support column fit tightly, and it is difficult to protect the safety of the main structure. At the same time, the degree of intelligence is low, and it is difficult to grasp the working status and performance changes of the support in real time, and it is difficult to discover and solve problems in time. Therefore, it is necessary to propose a steel structure sliding support for civil engineering. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figure 1 - Figure 6 As shown, a steel structure sliding support for civil engineering includes:

[0042] Data acquisition and processing module: responsible for receiving data collected by sensors fixedly installed inside the main body 1, and processing and analyzing the data;

[0043] Early warning and alarm module: responsible for automatically issuing early warning or alarm signals based on the set thresholds and data analysis results;

[0044] Data storage and management module: responsible for storing and managing the collected data to form a historical database;

[0045] User interface and interaction module: responsible for providing an intuitive user interface;

[0046] Intelligent analysis and decision-making module: responsible for in-depth analysis and mining of the working status and performance data of the support body 1;

[0047] The data acquisition and processing module, the early warning and alarm module, the data storage and management module, the user interface and interaction module and the intelligent analysis and decision-making module are all fixedly connected to the main body 1. A support column 6 is movably installed inside the support main body 1. The support column 6 penetrates the support main body 1 and extends to the upper part of the support main body 1. The upper part of the support main body 1 is provided with a limiting mechanism for preventing the support column 6 from tilting. The limiting mechanism includes a first mounting frame 5 fixedly installed on the upper part of the support main body 1, and a limiting cylinder 3 is fixedly installed on one side of the first mounting frame 5. The output end of the limiting cylinder 3 is provided with a double-sided rack 4. The double-sided rack 4 It is slidably connected to the support body 1, and both sides of the bilateral racks 4 are meshed with incomplete gears 7. The incomplete gear 7 is rotatably connected to the first mounting frame 5. One side of the incomplete gear 7 is fixedly connected to the first connecting plate 8, and the side of the first connecting plate 8 away from the incomplete gear 7 is rotatably connected to the sixth connecting plate 23, and the side of the sixth connecting plate 23 close to the first connecting plate 8 is rotatably connected to the second connecting plate 9, and the side of the second connecting plate 9 away from the sixth connecting plate 23 is rotatably connected to the first mounting frame 5, and the side of the sixth connecting plate 23 close to the supporting column 6 is fixedly connected to the limiting plate 24.

[0048] The working principle of a steel structure sliding bearing for civil engineering proposed by the present invention is that the data acquisition and processing module can monitor the displacement, force, vibration and other parameters of the bearing body 1 in real time by installing displacement sensors, pressure sensors, acceleration sensors, etc. inside the bearing body 1, and provide a basis for the working state and performance evaluation of the bearing body 1. The historical database formed by the data storage and management module can provide data support for subsequent data analysis, performance evaluation and maintenance. The user interface and interaction module facilitate users to view the working state and performance data of the bearing.

[0049] When it is necessary to keep the support column 6 and the support body 1 in close contact, the limit cylinder 3 is started. The limit cylinder 3 will cause the double-sided racks 4 set at the output end to slide on the upper part of the support body 1 toward the limit cylinder 3. When the double-sided racks 4 slide, the incomplete gears 7 meshing on both sides will rotate at the same time. The rotation of the incomplete gear 7 will cause the first connecting plate 8 to move toward the side close to the support column 6. The rotation of the first connecting plate 8 will drive the rotatably connected sixth connecting plate 23 to move toward the support column 6, and the second connecting plate 9 rotatably connected to the sixth connecting plate 23 and the first mounting bracket 5 are rotatably connected, so that the sixth connecting plate 23 can remain stable when rotating, that is, the sixth connecting plate 23 can drive the limit plate 24 to approach the support column 6, that is, the symmetrically arranged limit plates 24 can be used to limit the support column 6, so that the support body 1 and the support column 6 are kept in close contact, thereby protecting the safety of the main structure.

[0050] In one embodiment, for the above-mentioned support column 6, a third connecting plate 10 is provided at the lower portion of the support column 6, and a shock-absorbing mechanism for absorbing shock when the support column 6 slides downward is symmetrically provided on both sides of the third connecting plate 10, and the shock-absorbing mechanism includes a second fixing rod 14 fixedly connected to the lower portion of the third connecting plate 10, and the second fixing rod 14 is rotatably connected to a fourth connecting plate 15.

[0051] In one embodiment, for the above-mentioned fourth connecting plate 15, the fourth connecting plate 15 is rotatably connected to the slider 16, the slider 16 is slidably connected to the second mounting frame 21, one side of the slider 16 is fixedly connected to the second shock-absorbing spring 17, the side of the second shock-absorbing spring 17 away from the slider 16 is fixedly connected to the second mounting frame 21, and the side of the slider 16 away from the second shock-absorbing spring 17 is fixedly connected to the third shock-absorbing spring 20.

[0052] In one embodiment, for the above-mentioned third shock-absorbing spring 20, the side of the third shock-absorbing spring 20 away from the slider 16 is fixedly connected to a fixing plate 22, the fixing plate 22 and the second mounting frame 21 are fixedly connected, the side of the slider 16 close to the fourth connecting plate 15 is rotatably connected to the fifth connecting plate 18, the side of the fifth connecting plate 18 away from the slider 16 is rotatably connected to the third fixing rod 19, and the third fixing rod 19 and the support body 1 are fixedly connected.

[0053] The working principle of a steel structure sliding support for civil engineering proposed by the present invention is that when the supporting column 6 drives the third connecting plate 10 to move downward, the third connecting plate 10 will cause the fixedly connected second fixing rod 14 to move downward, and the second fixing rod 14 will cause the symmetrically rotatably connected fourth connecting plate 15 to rotate. The rotation of the fourth connecting plate 15 will cause the rotatably connected slider 16 to slide inside the second mounting frame 21. The sliding of the second mounting frame 21 will cause the rotatably connected fifth connecting plate 18 to rotate. The fifth connecting plate 18 is rotatably connected to the third fixing rod 19 fixedly connected inside the support body 1, and the second shock-absorbing spring 17 and the third shock-absorbing spring 20 are fixedly connected on both sides of the slider 16, respectively, so that the slider 16 can play a shock-absorbing role when sliding inside the second mounting frame 21, that is, the elastic deformation and energy dissipation of the structure can be achieved.

[0054] In one embodiment, for the above-mentioned third connecting plate 10, the lower part of the third connecting plate 10 is fixedly connected with a connecting block 11, and the lower part of the connecting block 11 is fixedly connected with a plurality of first shock-absorbing springs 13 for shock absorption, and the side of the first shock-absorbing spring 13 away from the connecting block 11 is fixedly connected to the support body 1.

The first fixing rod 12 and the connecting block 11 are slidably connected, and a plurality of fixing nails 2 for fixing the device are symmetrically arranged on both sides of the support body 1.

[0056] The working principle of a steel structure sliding support for civil engineering proposed by the present invention is that when the third connecting plate 10 moves downward, it will also drive the connecting block 11 to move downward, that is, the connecting block 11 will move downward on the first fixed rod 12 of the sliding connection. The downward movement of the connecting block 11 will compress the first shock-absorbing spring 13, that is, the shock-absorbing effect of the connecting block 11 can be activated, thereby ensuring the safety of the main structure.

[0057] In one embodiment, for the above-mentioned early warning and alarm module, the early warning and alarm module uses a threshold determination algorithm to determine whether the support body 1 is in an abnormal working state. The specific steps of the threshold determination algorithm are:

[0059] Setting the benchmark threshold: setting the benchmark threshold of each monitoring parameter according to the design specification of the support body 1, historical operation data and industry standards;

[0060] Threshold determination algorithm: The data collected in real time is compared with the set benchmark threshold. If the monitoring data exceeds the set threshold, the early warning or alarm mechanism is triggered. Different early warning levels and corresponding response measures can be set according to the degree of exceeding the threshold.

[0062] Data collection and processing: collecting data on working status and performance changes from sensors of the support body 1, and processing the collected data;

[0063] Feature extraction: extracting data that can reflect the working state and performance change characteristics of the support body 1 from the processed data;

[0064] Training SVM model: Use the extracted features and corresponding labels to train the SVM model, and select kernel function parameters to optimize model performance;

[0065] Model evaluation: Use cross-validation methods to evaluate the accuracy and generalization ability of the model, and adjust model parameters or select a more appropriate kernel function based on the evaluation results;

[0066] Intelligent analysis and decision-making: Integrate the trained SVM model into the intelligent analysis and decision-making module, receive the working status and performance change data of the support body 1 in real time, use the SVM model to analyze, and make decisions based on the analysis results.
