Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of mechanical structures, and more specifically, particularly relates to a self-adjustable large-curved segmented turning device. Background Art
[0002] In the implementation of shipbuilding, large linear surface segmentation is an important link. These segments usually have large sizes and complex curved shapes, and need to be accurately measured and positioned to ensure the accuracy and quality of the overall hull. During the construction process, large linear surface segments usually adopt a modular construction method, that is, the hull is divided into multiple independent segments, which are then prefabricated and assembled separately. This construction method can greatly improve construction efficiency, reduce construction difficulty, and also reduce errors and waste. In order to ensure the accuracy and quality of large linear surface segments, advanced measurement and positioning technologies are required. Commonly used measurement methods include total stations, laser scanning, three-dimensional optical measurement, etc., which can obtain segment surface point cloud data and perform accurate measurement and positioning. At the same time, digital modeling and simulation technology is also needed to perform virtual assembly and collision detection on the segments to timely discover and solve potential problems.
[0003] The flipping of large linear surface segments is a challenging process. Due to the large segment size and complex surface shape, traditional flipping methods often fail to meet the requirements. Therefore, some special flipping methods are needed.
[0004] A common way to flip is to use hydraulic devices. By installing multiple hydraulic cylinders under the segment, the segment can be precisely controlled so that it can flip according to the preset trajectory. This method has high stability and reliability and is suitable for large, heavy and complex-shaped segments.
[0005] Another commonly used flipping method is to use a roller device to flip. By installing multiple rollers under the segment, it can be flipped under the action of rolling force. This method is suitable for segments with relatively regular shapes and light weight.
[0006] Regardless of the flipping method used, accurate measurement and positioning are required to ensure the accuracy and quality of the segmentation. At the same time, attention should be paid to safety issues and corresponding safety measures should be taken to ensure the safety of construction workers.
[0007] The lifting and flipping of large linear surface segments is a key process that involves multiple considerations and operations.
[0008] First, in order to ensure the stability of the segment during the lifting and turning process, temporary reinforcement measures are required. These reinforcement measures can be arranged and installed according to the structure, shape and turning direction of the segment to provide the necessary support and fixation.
[0009] Secondly, it is essential to know the weight of the section, its centre of gravity and the permissible load of the lifting equipment. This information will help determine the appropriate lifting and turning method, as well as selecting the appropriate lifting rings and auxiliary devices.
[0010] Next, it is necessary to formulate detailed lifting and flipping operation procedures. These procedures should include specific steps, safety precautions, personnel responsibilities, and emergency plans to ensure the smooth progress of the entire process.
[0011] Before hoisting and turning over, a series of inspection items are required, including whether the connections between the segmented outer plate and the frame and platform are completely removed, whether the welding of the lifting ring and reinforcement is firm, and whether the welding of the one square meter area of the segmented structure where the lifting ring is located is firm.
[0012] Finally, in the actual operation process, the operating procedures must be strictly followed, and close attention must be paid to the stability, safety and accuracy of the segmentation. If there are any abnormal situations, timely measures should be taken to adjust and deal with them.
[0013] Large linear curved surface segments usually have the technical problem of difficulty in turning over, which is mainly reflected in the following three aspects: (1) Due to the existence of many environmental and artificial random factors, it is impossible to use existing technical means to accurately simulate the turning over process of large linear curved surface segments, so it is impossible to determine the most suitable position to arrange the turning over lugs; (2) During the turning over process of large linear curved surface segments, the lugs are easily damaged by large lateral shear forces and cause serious safety accidents; (3) During the turning over process, the height difference of different hooks is not easy to adjust, resulting in inaccurate estimation of the center of gravity position, which is easy to cause dangerous situations of instantaneous acceleration and reversal. Therefore, there are serious safety hazards in the implementation of the turning over process of large linear curved surface segments. Summary of the invention
[0014] In view of the deficiencies in the prior art, the present invention provides a large curved surface segment turning device that can be adaptively adjusted. The large curved surface segment is horizontally placed and fixed on a platform, and the platform is rotated around a rotating roller to drive the large curved surface segment on the platform to turn over. This can solve the problem that the existing technical means cannot be used to accurately simulate the turning process of the large linear curved surface segment, and therefore it is impossible to determine the most suitable position to arrange the turning ears; during the turning process of the large linear curved surface segment, the ears are easily damaged by the large lateral shear force and cause serious safety accidents; during the turning process, the height difference between different hooks is not easy to adjust, resulting in inaccurate estimation of the center of gravity position, and easily causing dangerous situations of instantaneous acceleration and reversal.

Specifically, the bracket 1 fixedly installed on the ground can support the entire device and maintain stability. Of course, the bracket 1 can also use multiple pillars or tripods to increase stability. The rotating roller 2 installed at the top of the bracket 1 is used to support and rotate the large curved segment. The rotating roller 2 should have sufficient bearing capacity and rotational freedom to adapt to segments of different sizes and shapes. The further device also includes a platform 3 for placing and fixing the large curved surface segment. The platform 3 can be supported by a crude steel sleeve 4, and can adapt to segments of different sizes by the height of the crude steel sleeve 4.

The climbing ladder 6 installed inside the crude steel sleeve 4 is used to facilitate the staff to climb when the platform 3 is in a vertical state. The design of the climbing ladder 6 should consider personnel safety and convenience.
