Description

Technical Field

[0001] The present invention belongs to the technical field of ship design and manufacturing, and particularly relates to a method for generating a drawing of a ship section hoisting process diagram. Background Art

[0002] The design of traditional ship section hoisting process diagrams has the following technical pain points: 1) The information on the arrangement of lifting lugs and the calculation data of lifting weights are stored dispersedly, and multiple drawings need to be cross-compared during checking; 2) Manual marking is prone to data misalignment, especially the application of dynamic load coefficients is not standardized; 3) Design checking relies on empirical judgment and lacks a visual comparison mechanism; 4) The hoisting safety check stays at the stage of paper reports, and it is difficult to achieve the traceability of design data.

[0003] Designers only mark the weight of each lifting hook on the drawing in the general section mating lifting lug arrangement drawing, and it is not required during the design of section lifting lugs. This leads to the possible omission of the inspection of the lifting weights of each lifting hook during section hoisting during design and checking, resulting in the situation of incorrect design of the lifting lug tonnage.

[0004] Therefore, how to provide a method for generating a drawing of a ship section hoisting process diagram, which can reduce the safety hazard of tearing caused by the lifting lug tonnage being less than the actual bearing weight through constructing an associated marking system and an automatic checking mechanism for hoisting process parameters, and improve the efficiency of section stripping in the production department, has become an urgent technical problem to be solved. Summary of the Invention

[0005] An embodiment of the present invention provides a method for generating a drawing of a ship section hoisting process diagram, which can reduce the safety hazard of tearing caused by the lifting lug tonnage being less than the actual bearing weight through constructing an associated marking system and an automatic checking mechanism for hoisting process parameters, and improve the efficiency of section stripping in the production department.

[0006] In an embodiment of the present invention, a method for generating a drawing of a ship section hoisting process diagram is provided, including:

[0007] S101. Respectively generate the front view and top view of the ship section, and mark the arrangement position, quantity and tonnage information of the ship lifting lugs in the front view and top view;

[0008] S102. Synchronously mark the lifting weight information corresponding to each lifting hook in the front view and top view;

[0009] S103. Form a visual comparison relationship between the lifting weight information and the tonnage information of the corresponding lifting lugs for the design checkers to synchronously check the accuracy of the lifting lug tonnage design.

[0010] Further, the marking of the lifting weight information adopts the method of leading and marking with arrow lines, and the marking position of the lifting weight information is at the blank of the plane area where the corresponding lifting hook is located.

[0011] Furthermore, the lifted weight information is marked with a font color or font format different from that of the sling code tonnage information.

[0012] Furthermore, the method further includes:

[0013] Automatically extracting the load data of each lifting point based on the three-dimensional ship design model;

[0014] Automatically mapping the extracted load data to the corresponding marked positions on the two-dimensional process drawing.

[0015] Furthermore, the method includes a double-check mechanism, that is:

[0016] The designer must complete the lifted weight marking during the drawing output stage;

[0017] The checker needs to perform a matching check on the marked lifted weight and the sling code tonnage during the review stage.

[0018] Furthermore, the marking formats of the front and top views are unified with the sling arrangement drawing of the sub-assembly, forming a standardized expression system for the full-process lifting design.

[0019] Furthermore, the method further includes setting an automatic checking module;

[0020] When it is detected that the marked lifted weight exceeds the corresponding sling code tonnage, the automatic checking module automatically triggers a warning sign and generates a modification suggestion report.

[0021] Furthermore, the automatic checking module sets a safety threshold, and when the lifted weight reaches 85%-95% of the rated tonnage of the sling, the automatic checking module triggers a warning prompt.

[0022] Furthermore, the marked information includes a dynamic load coefficient, and the marked value of the lifted weight information is the product value of the actual lifted weight and the dynamic coefficient.

[0023] Furthermore, the method further includes: generating a lifting safety checking report, which includes the load-tonnage comparison data of each lifting point, the electronic signature of the checker, and the checking timestamp information.

[0024] The beneficial effects brought by the present invention are as follows:

[0025] As can be seen from the above solution, the embodiment of the present invention provides a method for generating a drawing of a ship section hoisting process diagram. By separately generating the front view and top view of the ship section, and marking the arrangement position, quantity and tonnage information of the ship lifting lugs in the front view and top view; synchronously marking the lifting weight information corresponding to each lifting hook in the front view and top view; forming a visual comparison relationship between the lifting weight information and the tonnage information of the corresponding lifting lugs, so as to enable the design verification personnel to synchronously check the accuracy of the lifting lug tonnage design.

Brief Description of the Drawings

[0026] Figure 1 It is a flowchart of a method for generating a drawing of a ship section hoisting process diagram according to an embodiment of the present invention. Detailed Description of the Embodiments

[0027] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] As Figure 1 shown, Figure 1 It is a flowchart of a method for generating a drawing of a ship section hoisting process diagram according to an embodiment of the present invention.

[0029] In the figure, a method for generating a drawing of a ship section hoisting process diagram includes:

[0030] S101. Separately generate the front view and top view of the ship section, and mark the arrangement position, quantity and tonnage information of the ship lifting lugs in the front view and top view;

[0031] S102. Synchronously mark the lifting weight information corresponding to each lifting hook in the front view and top view;

[0032] S103. Form a visual comparison relationship between the lifting weight information and the tonnage information of the corresponding lifting lugs, so as to enable the design verification personnel to synchronously check the accuracy of the lifting lug tonnage design.

[0033] In the embodiment of the present invention, by synchronously marking the lifting lug tonnage and the lifting weight information in the front view and top view of the ship section and generating a visual comparison relationship, the problem of separation between the lifting point data and the load can be solved. Among them, the verification efficiency is increased by more than 40%, and the risk of data misalignment is further reduced.

[0034] Among them, implementing double insurance for the drawing designers and drawing proofreaders can fundamentally solve the problem of incorrect design of the sling weight, and also ensure the hoisting safety from the source. When proofreading the drawings, the proofreader only needs to check the main top view to judge the accuracy of the sling weight design, improving the drawing issuance efficiency. After the designer fills in the lifting weight, it is also a check on their own hoisting plan. The technical solution of the present invention can reduce the safety hazard of tearing caused by the sling weight being less than the actual load, and further improve the sectional stripping efficiency of the production department.

[0035] In another embodiment of the present invention, the sling weight information is marked by an arrow line leading-out marking method, and the marking position of the sling weight information is located at the blank area of the plane area corresponding to the hook. Using the arrow line leading-out marking method can avoid the problem of the sling code marking overlapping with the large cabin ribs, and the marking position optimization algorithm improves the readability of the drawing by 35%.

[0036] In one embodiment of the present invention, the sling weight information is marked in a font color or font format different from the sling weight tonnage information. Marking with different font colors / formats, for example, red warning and green safety, compared with the pure text marking scheme, the recognition rate is increased by 50%, further reducing the probability of misreading.

[0037] In another embodiment of the present invention, the method further includes:

[0038] Automatically extracting the load data of each lifting point based on the three-dimensional ship design model;

[0039] Automatically mapping the extracted load data to the corresponding marking positions on the two-dimensional process drawing.

[0040] Among them, automatically extracting the load data based on the three-dimensional model and mapping it to the two-dimensional drawing optimizes the process of manually inputting data, effectively improving the data transfer efficiency and avoiding manual transcription errors.

[0041] In another embodiment of the present invention, the method includes a double-check mechanism, that is:

[0042] The designer must complete the sling weight marking during the drawing stage;

[0043] The proofreader needs to perform a matching check on the marked sling weight and the sling weight tonnage during the review stage.

[0044] Among them, the double-check mechanism based on mandatory design marking + verification matching check can make up for the defect of only relying on the 3D model verification after hoisting, effectively reducing the design error rate.

[0045] In another embodiment of the present invention, the marking formats of the main and top views are unified with the marking specifications of the overall section hoisting sling layout drawing, forming a standardized expression system for the full-process hoisting design.

[0046] Among them, the unified marking specifications and the connection with the general section loading drawings can effectively solve the problem of re-marking after the lifting code is removed3, and shorten the connection time of the construction links.

[0047] In yet another embodiment of the present invention, the method further comprises providing an automatic verification module;

[0048] When it is detected that the marked lifting weight exceeds the corresponding lifting code tonnage, the automatic verification module automatically triggers a warning sign and generates a modification suggestion report.

[0049] In the embodiment of the present invention, the automatic verification module sets a safety threshold, and when the hoisting weight reaches 85%-95% of the rated tonnage of the hoisting hook, the automatic verification module triggers an early warning prompt.

[0050] Among them, the automatic verification module and safety threshold warning (85%-95% rated load trigger) can effectively reduce the overload accident rate compared to the method of judging safety only by the wire angle, and provide real-time mechanical calculation support.

[0051] In one embodiment of the present invention, the annotation information includes a dynamic load coefficient, and the annotation value of the lifting weight information is the product of the actual lifting weight and the dynamic coefficient.

[0052] In another embodiment of the present invention, the method further includes: generating a hoisting safety verification report, wherein the hoisting safety verification report includes load-tonnage comparison data of each hoisting point, an electronic signature of the verification personnel, and verification timestamp information.

[0053] Among them, the electronic verification report contains a timestamp and electronic signature. Compared with the process that requires paper reports, it achieves full process traceability and meets the requirements of maritime safety audits.

[0054] In one embodiment of the present invention, taking a 175,000-ton bulk carrier as an example, through the technical solution of the present invention, the arrangement of the hoisting tags and the load marking are automatically generated, reducing 12 manual intervention links; the early warning module identifies three over-limit lifting points in advance in the 580-ton lifting task (the actual load of the rated 700-ton hoisting tags reaches 665 tons), avoiding major accidents; the electronic verification report is automatically generated in less than 3 minutes, which is 20 times more efficient than traditional manual reporting.

[0055] An embodiment of the present invention provides a method for drawing a ship section lifting process drawing, by respectively generating a main view and a top view of the ship section, and marking the layout position, quantity and tonnage information of the ship's lifting hooks in the main view and the top view; synchronously marking the lifting weight information corresponding to each hook in the main view and the top view; forming a visual comparison relationship between the lifting weight information and the tonnage information of the corresponding lifting hooks, so that design and verification personnel can synchronously check the accuracy of the lifting hook tonnage design.

[0056] The technical solution of the present invention can reduce the safety hazard of tearing caused by the lifting lug tonnage being less than the actual load and improve the segment stripping efficiency of the production department by constructing an associated annotation system for lifting process parameters and an automatic checking mechanism.

[0057] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
