Description

Technical Field

[0001] The present invention relates to the field of bridge construction, and in particular to a millimeter-level high-precision steel cage intelligent control device. Background Art

[0002] The connection between the pier and the pile foundation is destroyed by the debris flow, resulting in the pier root breaking, which will cause the bridge collapse accident. There are many reasons for the damage of the pier, one of which is the serious deformation of the steel bars in the connection section. When facing the impact perpendicular to the pier, the deformed steel bars cannot exert the tensile characteristics in the concrete. The structure is equivalent to only the concrete exerting the bending resistance. However, the characteristic of concrete is compression resistance, and the bending resistance is very poor, which causes the concrete to be broken when facing the horizontal debris flow. Among the causes of deformation, the installation deformation is more significant. Due to the rough construction of the pile foundation, the steel bars at the top of the pile will be damaged and deformed after the pile head is broken. It is always difficult to correct and reset it manually. Since the lower part of the pier steel cage is connected to the steel cage at the top of the pile foundation, this causes the steel cage at the bottom of the pier to deform, and its influence will extend to the entire lower part of the pier. The vicinity of this connection is very important in the stress of the entire bridge structure, but this part is always ignored because it is buried. There are about three factors that cause deformation: 1. Deformation of the steel cage before pouring, including deformation during production, transportation and hoisting. 2. Deformation and displacement caused by concrete extrusion and vibration during pouring. 3. Errors caused by post-construction testing equipment.

[0003] The existing method of regulating and controlling the steel cage is that after the steel cage is directly hoisted and closed, workers use tools such as calipers and crowbars to enter the mold for adjustment. This method has great disadvantages. First, the space inside the mold is extremely limited, which will seriously affect the workers' operation, especially the large deformation at the connection with the pile foundation. It is difficult for workers to reset such thick steel bars to the required position. Second, due to the limited space on the outer edge of the steel cage, manual calipers may have great errors. Third, traditional tools such as crowbars cannot accurately adjust the steel bars. Under the current high-standard construction requirements, it is impossible to control to the millimeter level. Moreover, due to the complexity of the operation, workers will inevitably lose efficiency and patience, and the final result is not ideal, which ultimately leads to unqualified piers.

[0004] Therefore, it is necessary to provide a millimeter-level high-precision steel cage intelligent control equipment to improve the construction accuracy and efficiency of the steel cage and reduce the quality problems and safety hazards caused by the deformation of the steel cage.

The equipment can achieve millimeter-level control of the steel cage through a high-precision distance measuring device and an electric telescopic rod to ensure that the size and shape of the steel cage meet the design requirements. It can monitor the distance between the steel cage and the mold and the distance between the steel bars in real time, and make real-time adjustments based on these data to ensure that the deformation adjustment process of the steel cage is accurate. Through the controller to achieve automatic control, the steel cage can be automatically deformed and adjusted according to the preset parameters and real-time measured data without manual intervention, which improves work efficiency.

At the same time, the equipment is easy and intelligent to operate and can be easily promoted and used in various construction projects.

[0019] 2. By considering the clearance distance from the steel bar to the mold, the steel bar diameter, and the initial deformation adjustment displacement of the electric telescopic rod, the equipment can more accurately calculate the required deformation adjustment displacement.

The equipment can determine the retraction deformation of the steel bar based on the steel bar diameter and the initial deformation adjustment displacement, so as to compensate in the actual adjustment process, further improving the control accuracy. By establishing a multivariate regression model, the equipment can predict the retraction deformation according to steel bars of different diameters, thereby realizing precise control of steel cages of different specifications.

[0030] Embodiment 1

[0031] Preferably, the fixing support rod 2 includes a fixed rod and a movable rod, one end of the fixed rod is fixedly arranged on the shell 1, the other end of the fixed rod is provided with a connecting groove, the inner wall of the connecting groove is provided with an internal thread, one end of the movable rod is provided with an external thread, and the movable rod is threadedly connected to the fixed rod.

[0032] Specifically, during construction, after the steel cage is hoisted and installed and the mold is closed, the operator carries a millimeter-level high-precision steel cage intelligent control device into the steel cage. For easy operation, a millimeter-level high-precision steel cage intelligent control device can be hoisted into the steel cage by a crane, and then the millimeter-level high-precision steel cage intelligent control device can be suspended in the center of the steel cage by a crane for subsequent deformation adjustment of the steel cage.

[0033] The operator can observe with the naked eye the violent deformation of the steel cage, especially the pier-pile connection and the stress-bearing part for hoisting. After the deformation position is determined, a millimeter-level high-precision steel cage intelligent control device can be moved to the deformation position by crane or manually. The movable rods of the fixing support rods 2 on both sides of the rotating shell 1 are adjusted to the length of the fixing support rods 2 until the movable rods are supported and fixed on the mold of the steel cage, thereby fixing the shell 1.

[0034] Preferably, the controller controls the deformation adjustment component to adjust the deformation of the steel cage according to the distance between the inner surface of the mold of the steel cage measured by the first distance measuring device and the distance between the steel bars of the steel cage measured by the second distance measuring device, including:

[0035] The deformation adjustment component is controlled to adjust the deformation of the steel cage according to the thickness of the protective layer, the diameter of the steel bar, the distance between the inner surface of the mold of the steel cage measured by the first distance measuring device, and the distance between the steel bars of the steel cage measured by the second distance measuring device.

[0036] Specifically, the controller controls the deformation adjustment component to adjust the deformation of the steel cage according to the thickness of the protective layer, the diameter of the steel bar, the distance between the inner surface of the mold of the steel cage measured by the first distance measuring device, and the distance between the steel bars of the steel cage measured by the second distance measuring device, including:

[0037] S11, calculating the clearance distance between the steel bar and the mold according to the distance between the inner surface of the mold of the steel cage measured by the first distance measuring device, the distance between the steel bars of the steel cage measured by the second distance measuring device, and the diameter of the steel bars, for example, the distance difference between the distance between the inner surface of the mold of the steel cage measured by the first distance measuring device and the distance between the steel bars of the steel cage measured by the second distance measuring device can be calculated, and the distance difference minus the diameter of the steel bar can be obtained to obtain the clearance distance between the steel bar and the mold;

[0038] S12, judging whether the clearance distance from the steel bar to the mold meets the preset adjustment requirement according to the thickness of the protective layer, if so, completing the deformation adjustment, if not, executing S13, wherein the preset adjustment requirement may be that the absolute value of the difference between the clearance distance from the steel bar to the mold and the thickness of the protective layer is less than the absolute value threshold;

[0040] For example, if the controller determines that the clearance distance from the steel bar to the mold does not meet the preset adjustment requirements, the controller will analyze the clearance distance from the steel bar to the mold according to the thickness of the protective layer and the clearance distance from the steel bar to the mold and there will be 6 results: left +, left -, left 0, right +, right -, right 0, etc. Among them, "+" represents thicker and needs to be pushed outward by the electric telescopic rod 3 for deformation adjustment, "-" represents thinner and needs to be pulled inward by the electric telescopic rod 3 for deformation adjustment, and "0" represents qualified and the telescopic rod on this side should remain stationary. "Left +" means that the electric telescopic rod 3 for deformation adjustment on the left side needs to push the steel bar outward, and "right -" means that the electric telescopic rod 3 for deformation adjustment on the right side needs to pull the steel bar inward. As an example only, if the clearance distance from the steel bar on the left side to the mold is less than the thickness of the protective layer, the analysis result is "left -", and if the clearance distance from the steel bar on the right side to the mold is greater than the thickness of the protective layer, the analysis result is "right +".

[0041] Preferably, the controller determines the deformation adjustment displacement of the electric telescopic rod 3 for deformation adjustment according to the clearance distance from the steel bar to the mold, including:

[0044] The deformation adjustment displacement of the electric telescopic rod 3 for deformation adjustment is determined according to its initial deformation adjustment displacement and the retraction deformation of the steel bar. For example, the initial deformation adjustment displacement plus the retraction deformation of the steel bar can be used as the deformation adjustment displacement.

[0045] Specifically, since the steel bars have a certain toughness when they are repaired, the shrinkage deformation needs to be calculated when adjusting the steel bar deformation to avoid deformation after unloading.

[0046] Preferably, the controller determines the retraction deformation of the steel bar according to the steel bar diameter and the initial deformation adjustment displacement of the electric telescopic rod 3 for deformation adjustment, including:

[0047] Acquire test data of a plurality of experimental steel bars, wherein the steel bar diameters of any two experimental steel bars are different, and the test data include shrinkage deformation amounts of the experimental steel bars corresponding to a plurality of test deformation adjustment displacements;

[0049] According to the test data of multiple experimental steel bars, the fitting parameters of the multivariate regression model are solved;

[0050] The shrinkage deformation of the steel bar is determined by a multiple regression model according to the diameter of the steel bar and the initial deformation adjustment displacement of the electric telescopic rod 3 for deformation adjustment.

[0051] Specifically, after the deformation adjustment displacement adjustment is completed, the electric telescopic rod 3 for deformation adjustment is unloaded first, but the position of the caliper 31 of the electric telescopic rod 3 for deformation adjustment does not move first, and the distance between the inner surface of the mold of the steel cage and the steel cage measured by the first distance measuring device and the distance between the steel bars of the steel cage and the steel cage measured by the second distance measuring device are read to calculate the clearance distance from the steel bars to the mold, and according to the thickness of the protective layer, determine whether the clearance distance from the steel bars to the mold meets the preset adjustment requirements. If it is determined that it does not meet the requirements, the electric telescopic rod 3 for deformation adjustment needs to be re-forced to adjust the steel bars again.
