Leveling method for generating wave shapes on ship T-slipway panel and segmented free edge

Abstract

The invention discloses a leveling method for generating wave shapes on a ship T-slipway panel and a segmented free edge. The leveling method is based on a following device, and the device comprises two C-shaped portal main plates arranged in parallel, a cross beam, positioning screws and a jack; one end of each portal main plate is provided with a main plate inserting groove, and the other end of each portal main plate is provided with a cross beam hole; the two ends of the cross beam are arranged in the cross beam holes; and the positioning screw is in threaded connection with the portal main plates. The leveling method comprises the following steps that 1, the two portal main plates are inserted into the two sides of the position, needing to be leveled, of a product from the main plate inserting grooves, and the distance between the two portal main plates is determined according to the size of the wave shapes of the position, needing to be leveled, of the product; 2, positioning screws are tightened to fix the portal main plates; 3, the cross beam is inserted into the cross beam holes in the two portal main plates; and 4, the jack is placed between the cross beam and the leveling position.

Description

technical field [0001] The invention belongs to the field of shipbuilding, and in particular relates to a leveling method for generating waves in the T-row panels and segmented free edges of the ship. Background technique [0002] In the process of building ships and ocean engineering, T-rows are often used as reinforcements to strengthen them. Especially with the start of construction of high value-added ships, a large number of reinforcements and reinforcements have been applied to these new ship types with T-row structures. In specific applications, the T-row panels and segmented free edges will have deformation defects such as waves (ruffles) due to welding stress during the welding process, which do not meet the precision process requirements and need to be heated and leveled. [0003] In the prior art, the following operation process is often adopted for the wavy leveling of T-row panels and segmented free edges: [0004] The first step is to determine the deformatio...

AI Technical Summary

Problems solved by technology

[0010] 1. It is difficult to ensure the precision process requirements by using pyrotechnic heating guns to heat and level in the natural state; making the construction complicated and slow and difficult to guarantee the precision

[0011] 2. The use of L-shaped riding boards and jacks requires professional welding personnel. Since the deformation defects such as T-row panels or segmented free-edge waves (ruffles) are not one, there may be multiple places, making the L-shaped riding boards The welding process is complicated and cumbersome. Once it is welded, it is difficult to effectively adjust it. The L-shaped saddle board must be removed and re-welded, which leads to slow progress in the entire construction process and even affects the overall leveling effect.

[0012] 3. The use of L-shaped riding board consumes a lot and is difficult to recycle. Since the L-shaped riding board needs to be welded on the product when it is used, the removal needs to destroy the welding point to complete, and it will inevitably leave scars that need to be polished. The whole process is labor-intensive Large, high risk factor, the surface quality of the finished product is out of control
