Problems solved by technology

[0003] 1. There is a lot of waste. All kinds of horse boards should use high-quality steel plates, and they must be cut off after use. When cutting, because the hull is damaged, the damaged parts need to be polished, repaired and then polished, and repaired again. Many times, the waste of manpower, material resources and raw materials also affects the quality of shipbuilding
[0004] 2. The cost is high. Manpower, motor vehicles, and cranes are required to transport the boards in place when they are closed. When using them, they must be welded one by one. The amount is very large. Generally, one piece must be welded every 200 to 300 mm.
Due to many barriers, it is impossible to realize welding automation
[0005] There is also a hull closing assembly method, as described in Chinese patent documents CN 102430867A and CN 201792106U, which is to weld a tack weld of about 300mm at a certain interval in the groove of two butt steel plates. Such a method is not only used in practice It is not strong enough, and the gasket needs to be pasted twice, and two times of grinding and two transition welding are used between the two tack welds, which increases the process and misoperation, and increases the working hours and labor costs

Embodiment Construction

[0077] as attached Figure 1 to Figure 8 A new method of shipbuilding assembly shown, comprising the following steps:

[0078] Step 1, cutting the groove: firstly locate the steel plate 1 that needs to be welded together by the hull, and cut the groove 7 according to the size required by the groove on the two butt joint edges of the steel plate 1 assembled by the hull;

[0079] Step 2. Grinding the groove: use a grinder to smooth the both sides of the groove 7 and the upper and lower sides of the steel plate within 100mm from the groove;

[0080] Step 3. Assemble the flat steel plate: as figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 As shown, the leveling equipment P is installed from the middle or one end of the butt joint 6 of the groove 7. The leveling equipment is a leveling equipment that only contacts with the top of the steel plate. Align and level off to form a leveled area a and maintain this state; the leveling equipment can be an oil top 3 and an oi...

Abstract

The invention discloses a novel hull erection method and belongs to the technical field of shipbuilding. The method includes the steps such as cutting grooves, grinding the grooves, assembling, leveling steel plates, applying pads, welding priming weld seams required for the production of positioning weld seams, welding the positioning weld seams, welding transition weld seams, welding erection weld seams, and polishing the erected whole. The novel hull erection method has the advantages that clamp plates are replaced with the positioning weld seams, the steps of welding the clamp plates and cutting the clamp plates are omitted, manpower and material resources and raw materials are greatly saved, less damage is caused to a hull, cost of polishing before and after welding is saved, and the basis for automated welding is laid.

Description

[0001] The invention relates to a shipbuilding and assembling method, which belongs to the technical field of shipbuilding. Background technique [0002] At present, when the segmental production in shipbuilding, the heald group and the hull are combined, the horse-board assembly method is still being used so far. That is, before the formal welding, the butt steel plates are first leveled. In order to ensure the smoothness of the two butt steel plates, it is necessary to weld the horse plates one by one to the two butt steel plates to fix them. Its defects are: [0003] 1. There is a lot of waste. All kinds of horse boards should use high-quality steel plates, and they must be cut off after use. When cutting, because the hull is damaged, the damaged parts need to be polished, repaired and then polished, and repaired again. Many times, wasting manpower, material resources and raw materials also affects the quality of shipbuilding. [0004] 2. The cost is high. Manpower or a m...
