Problems solved by technology
[0003] In the dynamic test of the military trade project, due to the insufficient strength of the fulcrum of the system and the effect of inertia, there was a case of damage to the deformation of the expansion joint. The expansion joint with deformation and damage had a greater adverse effect on the results of the dynamic test, and the deformation was damaged. If the expansion joint is not corrected in time, further deformation will occur, and in severe cases, it will be completely scrapped

Abstract
The invention discloses a device and a method for correcting a deformed expansion joint, and belongs to the technical field of ship construction. The device comprises a first adjustment plate, a second adjustment plate and more than two adjustment screw rods, wherein the first adjustment plate is used for being fixed to an upper flange disc of the expansion joint to be corrected; the second adjustment plate is used for being fixed to a lower flange disc of the expansion joint to be corrected; the two ends of each adjustment screw rod are connected with the first adjustment plate and the secondadjustment plate separately; the distance between the first adjustment plate and the second adjustment plate can be adjusted by rotating nuts on the adjustment screw rods, and the expansion joint tobe corrected is compressed or stretched, so that the expansion joint to be corrected is corrected. During the correction, a protective cable is embedded into a deformed thread, so that the uniformityof the gap of the thread after the correction can be effectively ensured; and during the correction, the deformed thread is heated, so that the deformation of the expansion joint to be corrected is promoted, and the correction difficulty of the expansion joint to be corrected is lowered. The correction method is high in operability, and is an indispensable emergency handling means.
Description
[0001] This invention is a divisional application of invention patent application 201810295871.9 on April 4, 2018 technical field [0002] The invention belongs to the technical field of ship construction, and in particular relates to a device and method for correcting a deformed expansion joint. Background technique [0003] In the dynamic test of the military trade project, due to the insufficient strength of the system fulcrum and the effect of inertia, there have been cases where the expansion joint is deformed and damaged. The damaged expansion joint has a great adverse effect on the results of the dynamic test, and the deformation is damaged. If the expansion joint is not corrected in time, further deformation will occur, and in severe cases, it will be completely scrapped. SUMMARY OF THE INVENTION [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a device and method for correcting a deformed expansion joint, wh...
