Description

Technical Field

[0001] The invention belongs to the field of building technology, and in particular relates to an adjustable portal frame support system and a use method thereof. Background Art

[0002] The traditional gantry support system relies on the combination of standard components to form a support system with a certain combination width. When using conventional methods to install gantry, most of the existing gantry brackets are single-leg designs, which cannot be adjusted according to actual working conditions and usage requirements, resulting in failure to meet usage requirements in some special environments. The installation process of some gantry brackets is relatively cumbersome, requiring more installation equipment, which increases installation costs and time.

[0003] After searching, for example, Chinese patent announcement number CN101886480A discloses an adjustable portal frame template support system (comparative document 1) that adjusts the width of the portal frame through a latch structure, CN215330475U discloses a portal support frame (comparative document 2) that supports the portal frame through fixed diagonal pillars, pads, weights and concrete beam top embedded reinforcement, and CN221372460U a portal frame type column support system (comparative document 3) that supports the portal frame through a triangular support structure formed between the main diagonal support beam, the lower cross beam and the column. Although the adjustment structure is adopted in comparative document 1, the width of the portal frame is set to be adjustable, which has the problem of limited bearing capacity. Comparative document 2 uses a fixed structure to support the portal frame, resulting in the problem that the portal frame structure is limited and cannot be adjusted. Comparative document 3 uses a triangular structure for support, and the support structure is stable but fixed. When the use situation requires adjustment, it is not convenient to adjust. For this reason, an adjustable portal frame support system and a method of use are designed that can be adjusted according to the situation of the portal frame. Summary of the invention

[0055] Embodiment 1

[0056] See attached Figure 1-4 As shown, the present invention provides a technical solution: an adjustable gantry support system, comprising a support structure 100, the support structure comprising a central sleeve 101, a plurality of oblique support rods 102 and horizontal support rods 103 are arranged in a circular array outside the central sleeve 101, and an outer end of the horizontal support rod 103 is welded with an outer support sleeve 104;

[0057] The automatic leveling structure 200 is installed at the bottom end of the outer support sleeve 104. The automatic leveling structure 200 includes a hydraulic push rod 201, a top plate 202 and a leveling member 203. The top plate 202 is welded to the top of the hydraulic push rod 201, and the leveling member 203 is fixed to the surface of the top plate 202.

[0058] Sensor feedback system 205, the sensor feedback system 205 is used to monitor the use status and horizontal status of the support system;

[0059] A control system 206, the control system 206 is used to automatically adjust the automatic leveling structure 200;

[0060] The topology map generation module 207 uses the data monitored by the sensor feedback system 205 to create a topological relationship diagram of the support points, which represents the mutual influence and connection relationship between the points, and accurately controls the various components and their mutual relationships in the leveling process of the support system to automatically adjust the structure to a preset horizontal state.

[0061] The embodiment of the present invention is also implemented through the following technical solutions.

[0062] In an embodiment of the present invention, the oblique support rods 102 are located above the horizontal support rods 103, the number of the oblique support rods 102 is the same as that of the horizontal support rods 103, and are welded to the central sleeve 101 and the outer support sleeve 104. The internal thread of the outer support sleeve 104 is equipped with an adjusting vertical rod 105, and the bottom end of the adjusting vertical rod 105 is clamped with the adjusting member. The central sleeve 101 is supported by the oblique support rods 102 and the horizontal support rods 103, and is connected to the gantry frame by using the central sleeve 101 and the outer support sleeve 104. The number of the outer support sleeves 104 is adjusted according to the structure of the gantry frame.

[0063] In the embodiment of the present invention, the leveling member 203 includes a fixed block 2031, a screw rod 2032 and a spring 2033. The fixed block 2031 is welded to the upper surface of the top plate 202. A center block adapted to the screw rod 2032 is arranged at the center of the fixed rod 2035. The fixed rod 2035 is fixed between the center block and the fixed block 2031. The spring 2033 surrounds the outer side of the screw rod 2032. The bottom end of the spring 2033 is fixedly connected to the center block. The upper end of the screw rod 2032 is connected to the adjustment vertical rod 105. The rotation of the screw rod 2032 is controlled by adjusting the vertical rod 105. The distance between the support system and the gantry frame is adjusted by rotating the adjustment vertical rod 105 and the screw 2032. The screw rod 2032 compresses the spring 2033 when it rotates downward, and the spring 2033 provides resistance during the rotation of the screw 2032. The force helps the staff feel the force of leveling, so as to control the leveling process more finely. When the desired horizontal position is reached, stop rotating the screw 2032, and the restoring force of the spring 2033 will maintain the current position to prevent position changes caused by external force or vibration, so that the support system can be manually adjusted. The screw 2032 and the fixed block 2031 cooperate to allow a small rotation to produce precise vertical displacement, which is suitable for occasions requiring high-precision leveling. The spring 2033 provides a damping effect, so that the leveling process will not become overly sensitive due to the rapid rotation of the nut, which helps to achieve smooth leveling. A supporting bottom block 204 is fixed to the bottom of the hydraulic push rod 201, and the position is installed through the supporting bottom block 204. It can be fixed to the ground with bolts, or the supporting bottom block 204 can be cast into a concrete brick for position fixation.

[0064] In an embodiment of the present invention, the sensor feedback system 205 includes a displacement sensor 2051, a level sensor 2052, an inclination sensor 2053 and a pressure sensor 2054. The displacement sensor 2051 is used to monitor the height change of the automatic leveling structure 200 and the support structure 100, and usually adopts a linear potentiometer, a magnetostrictive sensor or a laser ranging sensor, etc. The level sensor 2052 is used to monitor the horizontal position of the automatic leveling structure 200 and the support structure 100. The inclination sensor 2053 is used to monitor the inclination angle of the automatic leveling structure 200 to determine whether it reaches a horizontal state. The pressure sensor 2054 is used to monitor the pressure on the automatic leveling structure 200 to ensure that the supporting force is within a safe range and help determine whether it is evenly distributed. The displacement sensor 2051 is embedded in the top plate 202 and the gantry to monitor the height of the top plate 202 and the gantry. The level sensor 2052 is embedded in the support block and the inside of the top plate 202 and the bottom end surface of the gantry. The inclination sensor 2053 is arranged inside the top plate 202.

[0065] In an embodiment of the present invention, a control system 206, the control system 206 includes a central processor 2061, a control interface 2062 and a data processing module 2063, the central processor 2061 is used to control the adjustment of the automatic leveling structure 200;

[0066] The control interface 2062 is used for the staff to perform operations, including modifying the leveling parameters, monitoring the leveling process and manual intervention operations;

[0067] The data processing module 2063 is used to process the data from the sensor feedback system 205, including filtering, denoising and calibration, to improve the accuracy and reliability of the data.

[0068] In the embodiment of the present invention, the topology map generation module 207 includes a topology map mapping unit 2071, a state evaluation unit 2072 and a relative position determination unit 2073. The topology map mapping unit 2071 maps the data preprocessed by the data processing module 2063 to the topology map, the state (such as height, pressure) of each node is updated, the mutual relationship between the nodes is analyzed, and the influence relationship between the support points is determined;

[0069] The state evaluation unit 2072 is used to evaluate the difference between the current state of the support point and the preset state based on the topological map of the topological map mapping unit 2071, and determine the deviation data;

[0070] The relative position determination unit 2073 is used to calculate the relative position relationship between the support points to determine the equilibrium state of the overall structure.

[0071] In the embodiment of the present invention, the detailed processing steps of the status data difference of the status evaluation unit 2072 are as follows:

[0072] Step 1: Based on the topological diagram and the physical characteristics of the support points, use finite element software to establish a finite element model, calculate the stress, strain and displacement of each element, or establish a PID control model. The PID control model adjusts the support points through proportional, integral and differential control, which is suitable for simple leveling tasks. Perform support point layout analysis, interaction force analysis, structural stiffness evaluation and stability analysis. The geometric layout analysis is to analyze the layout of the support points in space to ensure that they are evenly distributed and there are no overly concentrated support points. Check the distance and angle between the support points to ensure that they meet the requirements of the structural design. Use structural analysis software for analysis;

[0073] Structural stiffness assessment is to evaluate the contribution of support points to structural stiffness, to ensure that the structure does not deform excessively when subjected to stress, and to check the connection method of the support points to ensure that the connection is firm and can transmit force and torque.

[0074] Analyze using finite element software;

[0075] Stability analysis uses the principle of static balance to ensure that the support points can stably support the structure 100 without overturning or instability. The location and distribution of the support points are checked to ensure the stability of the structure under various working conditions.

[0076] Step 2: Set the optimization goal of leveling, such as minimizing the height difference and pressure difference of all support points, determine the constraints of the optimization goal, such as the maximum adjustment amount and maximum bearing pressure of the support points, and design the leveling algorithm, such as using the gradient descent method, genetic algorithm, simulated annealing algorithm, etc. The algorithm needs to be able to handle multivariable optimization problems and take into account real-time requirements;

[0077] Step 3: Use an algorithm to calculate the specific adjustment amount of each support point that needs to be adjusted. The adjustment amount includes the height that the support point needs to rise or fall, the pressure change, etc., and preset a difference threshold to determine whether there is a difference in the status of the support point;

[0078] Step 4: convert the calculated adjustment amount into a specific control instruction to ensure that the instruction can be correctly understood and executed by the automatic leveling structure 200;

[0079] After executing the adjustment command, continue to monitor the sensor data, perform closed-loop feedback, and fine-tune the control command according to the actual leveling effect until the preset leveling accuracy is achieved;

[0080] The detailed steps of the relative position determination unit 2073 calculation are as follows:

[0081] Step A, using the support point relationship diagram of the topological graph, using analytic geometry to calculate the relative positions between the support points, such as distance, angle, etc.;

[0082] Step B, based on the calculated relative positions, analyzing the spatial layout, interaction force and stability of the support points;

[0083] Step C: matching the analysis result with the control scheme preset in the control system 206.

[0084] In the embodiment of the present invention, when the topological map is established by the map mapping unit, it is necessary to topologically number the supporting points. The detailed steps are as follows:

[0085] Step a, numbering from 1 to n according to the number of support points of the automatic adjustment structure;

[0086] Step b, selecting a numbering sequence according to the structure of the gantry, such as from left to right, from inside to outside, etc., to ensure that the numbering sequence can clearly reflect the physical position of the support point;

[0087] Step c, determining the numbering interval according to the number and area of ​​the gantries, and setting independent numbering intervals for gantries in different positions or areas;

[0088] Step d, synchronizing the number information to the control system 206, so that the control system 206 can control the corresponding hydraulic push rod 201 according to the number.

[0092] S2, pre-install inclination sensors 2053, level sensors 2052, displacement sensors 2051 and pressure sensors 2054 at various key points of the support system. The sensors monitor the horizontal state of the structure in real time and transmit the data to the control system 206;

[0093] S3, the control system 206 receives the sensor data, performs conventional preprocessing on the sensor data, generates a topology map using the topology map generation module 207, and adjusts the topology map according to the real-time transmitted data;

[0094] S4, the control system 206 formulates a leveling plan based on the results of the topology analysis and the sensor data change trend. The detailed steps of the sensor data change trend are as follows:

[0096] Step S42, performing data trend analysis of the sensor according to the chart, and using the data to establish a suitable model;
