Welding method for side guide plate of dredger steel pile trolley

Abstract

The invention belongs to the technical field of ships, and discloses a dredger steel pile trolley side guide plate welding method which mainly comprises the following steps that a side guide plate is installed on the longitudinal wall of a dredger body, a plurality of clamps are installed on the longitudinal wall in the length direction of the side guide plate, a cooling circulation pipe is installed between the clamps and the side guide plate, and cooling liquid is introduced into the cooling circulation pipe; the side guide plate and the longitudinal wall are fixedly welded, a plurality of first welding areas and second welding areas which are sequentially and alternately arranged are divided between the side guide plate and the longitudinal wall, one of the first welding areas is welded, then a knocking hammer is immediately used for evenly knocking the longitudinal wall at the position 27-33 mm away from a first welding line, and the second welding area is welded at the position 27-33 mm away from the second welding line. And the steps are repeated until all the first welding areas are welded, and then the method is repeated on the second welding areas until all the second welding areas are welded. According to the welding method for the side guide plate of the dredger steel pile trolley, welding stress and welding deformation generated in the welding process of the side guide plate are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a welding method for a side guide plate of a dredger steel pile trolley. Background technique [0002] The steel pile trolley is one of the core dredging equipment of the cutter suction dredger. During its travel, it needs to use the side guide plate on the longitudinal wall of the hull structure to accurately limit the position. The setting of the side guide plate must ensure that the steel pile platform In order to ensure the smooth running of the car, it is also necessary to ensure that the steel pile trolley maintains close contact with the hull to avoid excessive shaking of the steel pile trolley. In order to ensure the precise distance between the steel pile trolley and the side guide plate on the hull structure, the longitudinal wall of the hull structure at the corresponding position must be machined before the side guide plate is installed, and then the steel piles are wel...

Problems solved by technology

[0004] The object of the present invention is to provide a welding method for the side guide plate of the steel pile trolley of the dredger, so as to solve the lack of rigid fixation of the middle part of the side guide plate of the steel pile trolley of the dredger in the prior art and the welding of the side guide plate. The problem that the welding stress of the rear weld cannot be released in time
