DETAILED DESCRIPTION

[0034] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0035] See also Figure 1-7 The present embodiment provides an intelligent control system for the plane position of the overall lowering of a steel casing, including an intelligent control system and a limit device, and the intelligent control system includes a control terminal, a monitoring module and an intelligent adjustment module, the monitoring module and the intelligent adjustment module are respectively connected to the control terminal in communication, the monitoring system is used to monitor the plane position and the overall verticality of the steel casing, the intelligent adjustment module is used to fine-tune the limit device and the electric hydraulic jack 4, the control terminal is preset with deviation accuracy requirement parameters, the monitoring system feeds back the monitoring results to the control terminal, the control terminal compares the monitoring results with the deviation accuracy requirement parameters preset in the control terminal, and the control terminal issues instructions to the intelligent adjustment module according to the comparison results, so that the intelligent adjustment module intelligently adjusts the telescopic stroke of the electric hydraulic jack 4 to achieve precise adjustment of the limit device, and the limit device pushes the steel casing to accurately adjust the position of the steel casing.

[0036] It should be noted that the monitoring module is a key part of the intelligent control system for the overall lowering plane position of the steel casing. In addition, the monitoring module includes sensors, data acquisition cards, communication interfaces and data processing units, and the functions of the sensors, data acquisition cards, communication interfaces and data processing units are respectively: the sensors here include position sensors, inclination sensors, acceleration sensors, etc., which are used to monitor the position and verticality of the steel casing in real time; the data acquisition card is used to collect the signals sent back by the sensors and convert them into digital signals for processing; the communication interface is used to send the monitoring data to the control terminal; the data processing unit includes some microprocessors or dedicated data processing circuits for preliminary processing and filtering of data;

[0037] In order to enable the monitoring module to better monitor the plane position and overall verticality of the steel casing, the position sensors are arranged at the four corners or edges of the steel casing so as to monitor the position of the steel casing on the plane from multiple angles. The inclination sensor is installed at the center of the steel casing, or evenly distributed at the four corners of the steel casing to monitor the overall inclination angle of the steel casing. The acceleration sensor is installed at the key supporting point of the steel casing to monitor the dynamic response of the steel casing during the placement process. By reasonably arranging the above sensors, the monitoring module can comprehensively monitor the plane position and overall verticality of the steel casing. In addition, the monitoring module is not limited to the electronic components mentioned above. In addition to the above electronic components, it also includes other electronic components added according to the actual construction conditions and environment.

[0038] During the construction of offshore foundation steel casing, it is necessary to lower the steel casing. Due to the complexity and uncertainty of the offshore construction environment, it is difficult to ensure the plane position accuracy and vertical inclination of the steel casing during the lowering process, which puts high demands on the construction quality. At present, the traditional steel casing lowering construction method mainly relies on manual mechanical adjustment. This method is not only inefficient but also has great safety risks when the overall size and weight of the steel casing are large. In addition, the uncertainty of external factors in offshore construction, such as wind, waves, and water currents, makes it difficult for construction machinery to ensure the overall lowering stability of the steel casing. In the process of fine-tuning, problems such as the difficulty, high risk, and long time of manual adjustment are becoming increasingly prominent. In addition, engineering examples show that during the lowering construction of the steel casing, the impact of positioning fine-tuning on the overall lowering time is most significant.

[0039] In order to solve the above problems, in this embodiment, an intelligent control system is composed of a control terminal, a monitoring module and an intelligent adjustment module. The monitoring module and the intelligent adjustment module are respectively connected to the control terminal for communication. The monitoring system is used to monitor the plane position and the overall verticality of the steel casing. The intelligent adjustment module is used for the limit device and the electric hydraulic jack 4. The control terminal is preset with deviation accuracy requirement parameters. The monitoring system feeds back the monitoring results to the control terminal. The control terminal compares the monitoring results with the deviation accuracy requirement parameters preset in the control terminal. The control terminal sends instructions to the intelligent adjustment module according to the comparison results, so that the intelligent adjustment module intelligently adjusts and controls the electric hydraulic jack 4 to telescope and control the limit device, thereby achieving fine adjustment of the steel casing. This solves the problems of difficulty, high risk and long time consumption of manual adjustment during the fine adjustment process, and also reduces the overall lowering time for positioning and fine adjustment.

[0040] In order to ensure better stability when the steel casing is lowered as a whole, in one embodiment, the limiting device includes a box body 1, a base pad 101 and a base stiffening plate 102 arranged on the base pad 101 are provided at the bottom of the box body 1, the base pad 101 and the base stiffening plate 102, the base pad 101 and the steel casing wall 6 are all connected by welding, a supporting connecting plate 103 is provided on the side of the box body 1, a side plate 104 is provided on the top of the box body 1, a supporting I-beam 106 and a supporting I-beam bottom plate 109 arranged at the bottom of the supporting I-beam 106 are also provided at the bottom of the box body 1, the supporting I-beam 106 is arranged on the base pad 101, and the supporting connecting plate 103, the side plate 104, the supporting I-beam 106 and the supporting I-beam bottom plate 109 together constitute a working space for the electric hydraulic jack 4 to push up, such as Figure 3 , Figure 4 and Figure 5 As shown, the box body 1 here is the main supporting component of the intelligent adjustment system, which ensures the stability of the electric hydraulic jack 4 when pushing. The welding connection between the base pad 101 and the base stiffening plate 102, as well as the welding connection with the steel casing wall 6, can effectively enhance the stability and rigidity of the entire device and reduce deformation and vibration during operation. The setting of the top side panel of the box body 1 and the supporting I-beam 106 and the bottom plate thereof together constitute an operating space for the electric hydraulic jack 4 to push, which not only optimizes the working space, but also improves the working efficiency.

[0041] When the electric hydraulic jack 4 is pushing, due to the heavy weight of the steel casing as a whole, the electric hydraulic jack 4 may lose energy due to deviation or swing, thereby affecting the effect of fine adjustment. In order to solve this problem and ensure the stable progress of the fine adjustment pushing link, in one embodiment, a slide is provided inside the box body 1, and a limit plate 105 is provided on the support connecting plate 103 on the side of the slide, and a slide top plate 108 is provided at the bottom of the limit plate 105. A slide stiffening plate 107 is vertically provided at one end of the slide top plate 108 away from the support connecting plate 103, and the limit plate 105, the slide stiffening plate 107 and the slide top plate 108 form a whole. Figure 4As shown, the slideway here can ensure that the jack maintains linear motion during the pushing process, reduce energy loss caused by offset or swing, and thus improve the pushing efficiency. At the same time, the design of the slideway here helps to reduce the risk of jack failure due to operational errors or other factors, improve the reliability of the entire system, and ensure the stability of the fine-tuning pushing link. In addition, in order to ensure that the intelligent adjustment module intelligently adjusts and controls the electric hydraulic jack 4 to telescopically control the fine-tuning limit device, so as to achieve fine-tuning of the steel casing, in addition to using the box body 1 of the limit device as the main supporting component of the intelligent adjustment system, it is also necessary to have a pushing adjustment component that cooperates with the support component. The two cooperate with each other to achieve fine-tuning of the steel casing. In this regard, in one embodiment, the limit device also includes a support arm 2. The support arm 2 here is the main pushing adjustment component of the intelligent adjustment system. One end of the support arm 2 is in contact with the base steel casing 7 on the steel casing. The other end of the support arm 2 is provided with an I-beam slide rail 201 that cooperates with the slideway. The support arm 2 includes two support arm side plates 209, an arc-shaped support plate 202, and a support arm bottom plate. 203, jack push plate 204, support arm cover plate 205, first stiffening plate 207 and second stiffening plate 208. The arc support plate 202 is designed to be arc-shaped to ensure that the arc support plate 202 and the cap steel casing 7 are fully fitted and subjected to force. The two support arm 2 side plates are symmetrically arranged at the same end of the I-beam slide rail 201. One end of the two support arm side plates 209 is connected through the arc support plate 202, and the other end of the two support arm side plates 209 is connected through the jack push plate 204. The two support arm side plates 209, the arc support plate 202 and the jack push plate 204 together constitute a first closed area. The first stiffening plate 207 and the second stiffening plate 208 are arranged in a criss-cross manner in the first closed area. Figure 7 As shown, in the first closed area, the number of the second stiffening plates 208 is three, and the number of the first stiffening plates 207 is one, and the first stiffening plate 207 is an arc structure, which matches the structure of the arc support plate 202. The three second stiffening plates 208 are staggered with the first stiffening plates 207 to further improve the stability of the first closed area. The arc support plate 202 is connected to one end of the jack push plate 204 through the support arm cover plate 205, and the other end of the arc support plate 202 is connected to the jack push plate 204 through the support arm bottom plate 203. A second closed area is formed between the arc support plate 202, the jack push plate 204, the support arm cover plate 205 and the support arm bottom plate 203. The first stiffening plate 207 and the horizontal stiffening plate 206 are crisscrossed in the second closed area, as shown in FIG. Figure 6As shown, there are three horizontal stiffening plates 206 and one first stiffening plate 207 in the second closed area. The first stiffening plate 207 and the horizontal stiffening plate 206 further improve the stability of the second closed area. The arc support plate 202 can be reprocessed according to the remaining steel casing wall panels cut on site. Lubricating oil can be applied to its contact surface and polytetrafluoroethylene sliding plates can be attached. The purpose of applying lubricating oil is to reduce the friction between the arc support plate 202 and the steel casing wall panels, making the movement smoother and reducing the movement resistance. Polytetrafluoroethylene has excellent anti-friction performance and its friction coefficient is extremely low, which can effectively reduce the friction between the arc support plate 202 and the steel casing wall panels.

[0042] After the fine adjustment of the limit of the steel casing is completed, in order to further increase the connection strength between the limit device and the steel casing, make the limit device more stable and not easily displaced by external force or vibration, in one embodiment, a limit welding plate 5 for increasing stability is provided between the base steel casing 7 on the steel casing and the limit device. The limit welding plate 5 can effectively increase the contact area between the base steel casing 7 and the limit device, thereby improving the overall stability and reducing the displacement caused by vibration or external force.

[0043] Since the steel casing is finely adjusted, in order to ensure fine adjustment of the steel casing when it is pushed up by the electric hydraulic jack 4, in one embodiment, a jack base pad 3 for reducing the stroke of the electric hydraulic jack 4 is provided between the box body 1 and the electric hydraulic jack 4. The jack base pad 3 is the base pad 3 of the electric hydraulic jack 4, which is used to support the jack from the rear side so as to appropriately reduce the stroke of the electric hydraulic jack 4. By placing pads under the jack base, the working stroke of the jack can be appropriately reduced to avoid unnecessary pressure or damage to the lifted object due to excessive stroke. In addition, reducing the jack stroke can provide more precise control to avoid inaccurate positioning due to excessive stroke.

[0044] A method for using an intelligent control system for the plane position of a steel casing overall lowering includes the following steps:

[0045] S1: According to the height and plane size of the steel casing wall 6 on site, determine the plane and elevation point locations of the intelligent adjustment system, and according to the diameter of the steel casing, the size of the jack used, and the distance between the steel casing and the inner wall of the steel casing, determine the size of the arc plate of the front support arm 2 of the limit device and the size of the overall support box 1;

[0046] S2: According to the size and material type of the intelligent adjustment system determined in step S1, the limit device is processed and manufactured, and at the same time, it is necessary to ensure that the processing error of each rod does not exceed 3mm and the height difference of the slideway steel does not exceed 10mm; the 3mm and 10mm here are determined according to the use environment, precision requirements and construction standards. The purpose of ensuring that the processing error does not exceed 3mm and the height difference of the slideway steel does not exceed 10mm is mainly to ensure the accuracy and reliability of the entire structure;

[0047] S3: Install the plane and elevation point positions according to the intelligent adjustment system determined on site, install the electric hydraulic jack 4 in advance, and retract the limit device to the minimum length while ensuring the top travel distance requirement of the limit device to avoid affecting the initial lowering alignment of the casing as a whole. At the same time, install the monitoring module and the control terminal, and realize the full intelligent interconnection of the three. The monitoring module uses GPS intelligent monitoring points, and the GPS intelligent monitoring points are determined according to the on-site construction steel casing structure. As many points as possible must be set to ensure the accuracy of the monitoring results, improve the accuracy of the plane position intelligent control system and construction efficiency;

[0048] S4: The steel casing is lowered and aligned as a whole, and the plane position intelligent control system runs synchronously. The monitoring module, control terminal, and intelligent adjustment module are fully intelligently interconnected to prevent the steel casing from tilting too much as a whole, thereby causing excessive sliding displacement of the slideway steel inside the limit device;

[0049] S5: The monitoring module monitors the plane position and overall verticality of the steel casing at all times, and can also simultaneously use tools such as a total station to assist in monitoring the plane position offset and overall verticality offset of the steel casing;

[0050] S6: The monitoring module transmits the monitoring result feedback to the control terminal, and the control terminal compares the monitoring result with the deviation accuracy requirement parameters preset in the control terminal, and controls the telescopic control limit device of the electric hydraulic jack 4 through intelligent adjustment, so as to achieve fine adjustment of the steel casing;

[0051] S7: The intelligent control is finished, the fine adjustment is in place, and the cap steel casing 7 on the steel casing is fixed to the limit device by the limit welding plate 5;

[0052] S8: The fine adjustment and limit adjustment of the steel casing is completed, and then other fine adjustment and limit auxiliary equipment such as the plane position intelligent control system, the electric hydraulic jack 4 and the jack base pad 3 are removed.

The fine adjustment device is combined with the limit device. After the fine adjustment is in place, the limit plate 105 with equal strength can be welded on the outside of the device to improve the material utilization rate and construction efficiency, and avoid the on-site limit device from setting up points again for production and installation. Compared with the traditional construction method, the construction method of the present invention can improve the problems of the steel casing lowering construction platform and the vertical position fine adjustment accuracy, effectively improve the steel casing lowering flatness and vertical accuracy, and after comprehensive application, it can improve the steel casing lowering construction efficiency, shorten the steel casing hoisting time, and avoid the safety impact of uncertain factors at sea on the steel casing hoisting construction as much as possible.
