Abstract
The invention discloses a marking off method for self-propelled drag suction dredger ship building. The marking off method includes that: inspecting whether levels and specifications of steels are matched with drawing part requirements or not; if severe defects like pocks and ferric oxide indentations are discovered, reporting the defects to related inspectors and correcting according to related rules of precision standards; copying furnaces batch numbers for important parts like shell plates of the whole dredger ship, a main machine base, a crane base and head and tail columns and parts utilizing high-strength steel, and distinguishing high-strength plates by different priming paint colors as far as possible during preprocessing; marking off and grinding manholes, vent holes, water flow holes, lightening holes and technical holes; clearly marking corresponding processing information for plates and profiles requiring cold bending processing or water and fire bending processing by marking off workers. The marking off method for the self-propelled drag suction dredger ship building is simple, easy to operate and good in working efficiency.
Description
Technical field
The present invention relates to a kind of shipbuilding method.
Background technology
Existing trailing suction hopper dredger machine ship building setting out method complexity, working effect is undesirable.
Summary of the invention
The object of the present invention is to provide a kind of easy, effective trailing suction hopper dredger machine yard number material method.
Technical solution of the present invention is:
A kind of trailing suction hopper dredger machine yard number material method, is characterized in that: when the number of comprising the following steps: material, should check steel rank, whether steel specs mates with the requirement of drawing part; If number material when finds that there is compared with critical defect, as pit, ferric oxide impression etc. should, in time to relevant inspector's reflection, then be repaired by the relevant regulations of accuracy standard; In number when material, must and be used the position of high strength steel to significant points such as full planking and main engine bed, crane pedestal, head and the tail posts, should make a copy of stove lot number, and high-strength plate should be as far as possible with different priming paint color differentiatings in the time of pretreatment; Number when material, various manholes, breather hole, discharge orifice, lightening hole, auxiliary hole equal sign should be gone out and grinding process; Need clod wash processing or extreme misery bending machining sheet material, section bar liner-off should indicate corresponding machining information on part.
Different priming paint colors comprise red, yellow, blue, white.
Different priming paint colors comprise green grass or young crops, Huang, purple, white.
The inventive method is easy, easy to operate, good working effect.
Below in conjunction with embodiment, the invention will be further described.
Detailed description of the invention
A kind of trailing suction hopper dredger machine yard number material method, should check steel rank when the number of comprising the following steps: material, whether steel specs mates with the requirement of drawing part; If number material when finds that there is compared with critical defect, as pit, ferric oxide impression etc. should, in time to relevant inspector's reflection, then be repaired by the relevant regulations of accuracy standard; In number when material, must and be used the position of high strength steel to significant points such as full planking and main engine bed, crane pedestal, head and the tail posts, should make a copy of stove lot number, and high-strength plate should be as far as possible with different priming paint color differentiatings in the time of pretreatment; Number when material, various manholes, breather hole, discharge orifice, lightening hole, auxiliary hole equal sign should be gone out and grinding process; Need clod wash processing or extreme misery bending machining sheet material, section bar liner-off should indicate corresponding machining information on part.
