Problems solved by technology

[0002] 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 method for correcting a deformation expansion joint, and belongs to the technical filed of ship construction. The device comprises a first adjusting plate, a second adjusting plate and more than two adjusting screws. The first adjusting plate is used for being fixed to an upper flange of an expansion joint to be corrected, and the second adjusting plate is usedfor being fixed to a lower flange of the expansion joint to be corrected. The two ends of the adjusting screws are separately connected with the first adjusting plate and the second adjusting plate.By rotating nuts on the adjusting screws, the distance between the first adjusting plate and the second adjusting plate can be adjusted to compress or stretch the expansion joint to be corrected so asto correct the expansion joint to be corrected. During correcting, a protection cable is embedded in a deformation thread, the uniformity of thread clearance after correction can be effectively guaranteed, during correction, the deformation thread is heated to promote the deformation of the expansion joint to be corrected, and the correction difficulty of the expansion joint to be corrected is reduced. The correction method is high in operability and is an indispensable emergency treatment method.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, in particular to a device and method for correcting a deformed expansion joint. Background technique [0002] 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. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a device and method for correcting deformed expansion joints, which are used for correcting deformed and damaged expansion joints. [0004] The purpose of the present in...
