Freely adjusted electromagnetic adsorption-type flexible bed-jig structure

Abstract

The invention relates to a freely adjusted electromagnetic adsorption-type flexible bed-jig structure, comprising a bed-jig base (1), a lower spiral tube (2), a first connection ear (3), an upper spiral tube (4), a protective flange (5), a current controller (6), a wire (7), a full-angle rotation head (8), an electromagnetic-type backing plate with radian (9), a second connection ear (3), a lateral support rod (11) and a base reinforcing rib (12). According to the requirements of body section, the electromagnetic-type backing plates with radian (9) with different curvatures are designed and generated; the connection of the electromagnetic-type backing plates with radian (9) and the segment is adsorbed on the segmented body through the electromagnetic effect; the direction of the electromagnetic-type backing plate with radian (9) is controlled by a full-angle rotary head (8); the micro-macro adjustment of the bed-jig height is finished through the threaded connection of the lower spiral tube (2) and the upper spiral tube (4); and the arrangement number of the bed jigs is set according to the segmented weight and the bed-jig strength.

Description

technical field [0001] The invention relates to the field of large-scale close-up construction of ships and marine engineering equipment, in particular to a freely adjustable electromagnetic adsorption type flexible tire frame structure, which is especially suitable for large-scale segmental and complex shape segmental segmental close-up construction. It has strong operability, good applicability, high work efficiency, reusability and high processing quality. Background technique [0002] In the process of building large ships and marine products, etc., the method of segmented construction is often used to divide the ship into several parts, build them separately, and then close up the segments. Due to the irregular shape of each segment, during the construction and closing process of the segment, the tire frame is required to provide support for the segment to ensure its accuracy and stability and prevent the hull from deforming. The tire frame is a special process equipme...

AI Technical Summary

Problems solved by technology

[0004] 1. The length of the support rod is selected according to the height from the bottom of the tire frame to the bottom of the corresponding section, and is cut off when the tire frame is separated from the section, and cannot be reused, which leads to waste of materials and increase in processing costs , the processing quality is poor, the equipment occupancy rate is high, and the construction period is extended

[0005] 2. The connection between the support rod and the segment is completed by welding. After the transportation and closing are completed, the support rod is disconnected from the segment and the fracture is smoothed. This method will cause damage to the material at the welded part of the segment damage, increase the risk of corrosion and damage, increase the safety hazards of ships and marine equipment, and increase the follow-up workload

[0006] 3. The support rod and the segment are connected by electric welding. The small connection area requires multiple support rods to complete the support of the segment. The number of tire frames is large, the construction period is long, and the equipment occupancy rate is high

[0007] 4. For complex curved surface segments, the design and adjustment of the existing tire frame is time-consuming and laborious
