Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the prior art, the corresponding slings are generally selected and applied directly according to the experience of the operating worker. However, due to the instability of the offshore environment, the physical data such as the motion state and the center of gravity of the structure to be transported also change, so that for operators with less experience, the slings cannot be accurately selected according to the physical data of the structure to be transported, and the transportation safety cannot be guaranteed.
In order to solve the above problems, according to the sling selection method, the sling selection device, the electronic device and the storage medium provided by the embodiment of the application, sling information corresponding to a current sling arranged on a guide frame of a transport ship, physical information of a cargo to be transported and environmental information of a target transport position are acquired; the physical information comprises the weight, the gravity center position and the shape of the goods to be transported, and the environmental information comprises wind speed, wind direction, flow speed, wind wave data and surge data; the sling information includes: sling type, sling number and installation position; determining the rolling angle of the goods to be transported and the rolling angle of the guide frame according to the physical information, the environmental information and the sling information of the goods to be transported; generating a safety evaluation result according to the relation between the rolling angle of the goods to be transported and the rolling angle of the guide frame and the preset rolling angle threshold of the goods to be transported and the preset rolling angle threshold of the guide frame; and selecting the sling to install according to the safety evaluation results corresponding to all the slings.

The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, a description will be given of a configuration of a sling selection system according to the present application:
the sling selecting method, the sling selecting device, the electronic equipment and the storage medium are suitable for helping operators with poor experience to accurately select the sling so as to improve the transportation safety. Fig. 1 is a schematic structural diagram of a sling selection system according to an embodiment of the present invention, which mainly includes a database and a sling selection device for selecting a sling. The database stores a large amount of environment information and various sling information, the environment information covers hydrological and meteorological data and the like, and an operator can adaptively increase, delete, modify and check the data in the database according to actual conditions. Specifically, the corresponding environment information can be acquired in the database according to actual requirements, safety evaluation is performed according to the physical information of the current goods to be transported, the environment information of the target transportation position and sling information of the current sling to be selected, and a corresponding safety evaluation result is generated so that an operator can screen the slings, and therefore safety of sling selection is improved.
The embodiment of the application provides a sling selecting method, which is used for helping operators with less experience to accurately select slings so as to improve the transportation safety. The execution subject of the embodiment of the present application is an electronic device, such as a server, a desktop computer, a notebook computer, a tablet computer, and other electronic devices that can be used for sling selection.
As shown in fig. 2, a schematic flow chart of a sling selection method provided in an embodiment of the present application is shown, where the method includes:
The physical information comprises the weight, the gravity center position and the shape of the goods to be transported, and the environmental information comprises wind speed, wind direction, flow speed, wind wave data and surge data; the sling information includes: sling type, sling number and mounting location.
It should be explained that the goods to be transported can be large-scale structures such as a jacket, a pile sinking positioning frame and a pile holding frame. The wave data includes wave height of the wave and period of the wave, and the surge data includes wave height of the wave and period of the wave.
And step 202, determining the rolling angle of the goods to be transported and the rolling angle of the guide frame according to the physical information, the environmental information and the sling information of the goods to be transported.
It should be explained that the rolling angle of the goods to be transported refers to the left-right swing amplitude of the goods to be transported during the transportation process of the goods to be transported, and correspondingly, the rolling angle of the guide frame refers to the left-right swing amplitude of the guide frame during the transportation process of the goods to be transported, which particularly reflects the balance between the goods to be transported and the guide frame.
Specifically, in an embodiment, in order to improve the reliability of the safety evaluation result, the rolling angle of the cargo to be transported and the rolling angle of the guiding frame may be determined according to the physical information of the cargo to be transported, the environmental information, the sling information, and the physical information of the transport ship.
The physical information of the transport ship comprises shape data and weight distribution data of the ship to be transported. The shape data mainly come from a shape line graph and a shape value table of the transport ship, the weight distribution data is mainly determined according to the loading condition of the transport ship, and all equipment and materials of the whole ship need to be classified and counted to determine the gravity center position of the ship.
Specifically, in an embodiment, the simulation model may be generated according to physical information of the cargo to be transported, preset motion parameter information, and sling information.
Furthermore, the environment information can be input into the simulation model to obtain the simulation motion information of the simulation model; and determining the rolling angle of the goods to be transported and the rolling angle of the guide frame according to the simulation motion information.
Fig. 3 is a schematic structural diagram of an exemplary simulation model provided in an embodiment of the present application. The simulation model can be specifically established by adopting MOSES software, the specific model establishment mode can refer to the prior art, and the embodiment of the application is not limited.
It should be explained that the MOSES software is a software tool integrating modeling, simulation and analysis of ocean engineering, and has a simple operation process and high accuracy.
Specifically, the transportation ship can be subjected to slice modeling according to the line drawing data, a slice model is established according to the ship outline dimensions at different rib positions, slices from the bow to the stern form an integral model of the ship, and the modeling method is called a slice method.
Specifically, the obtained simulation model is subjected to transportation simulation to obtain simulation motion information of the simulation model under the current working condition, and then the rolling angle of the goods to be transported and the rolling angle of the guide frame are determined. The simulation model can be controlled to carry out transportation simulation by setting motion parameter information and environment information of the simulation module, wherein the motion parameter information mainly comprises the radius of gyration and the like of transportation.
And 203, generating a safety evaluation result according to the relations between the rolling angle of the goods to be transported and the rolling angle of the guide frame and the preset rolling angle threshold of the goods to be transported and the preset rolling angle threshold of the guide frame.
Wherein, the preset goods to be transported roll angle threshold value and the preset guide frame roll angle threshold value can be set according to actual conditions, and the embodiment of the application is not limited.
Specifically, in one embodiment, it may be determined whether the rolling angle of the cargo to be transported/the rolling angle of the guide frame is greater than the threshold value of the rolling angle of the cargo to be transported/the threshold value of the rolling angle of the guide frame; and when the rolling angle of the goods to be transported/the rolling angle of the guide frame is larger than the threshold value of the rolling angle of the goods to be transported/the threshold value of the rolling angle of the guide frame, generating alarm information.
Correspondingly, when the rolling angle of the goods to be transported and the rolling angle of the guide frame are not larger than the threshold value of the rolling angle of the goods to be transported and the threshold value of the rolling angle of the guide frame, the current sling is determined to be a candidate sling.
It should be explained that the reason why the cargo roll angle/guide frame roll angle to be transported is larger than the cargo roll angle threshold/guide frame roll angle threshold to be transported may be improper selection of the model of the slings, improper selection of the number of the slings or improper installation position.
Specifically, after the alarm information is generated, the alarm information is reported to remind an operator that the current sling needs to be adjusted, wherein the reporting mode of the alarm information can be a prompt tone or a prompt lamp, and the embodiment of the application is not limited.
The candidate sling specifically refers to a sling which can meet the safety requirement. But considering the actual transportation costs, whether to choose the candidate sling for installation requires further consideration by the operator.
Specifically, in an embodiment, in order to further improve the transportation safety, the maximum tension of the candidate sling may be determined according to the physical information, the environmental information and the sling information of the goods to be transported;
judging whether the maximum tension of the candidate sling is greater than a tension threshold corresponding to the sling model;
and when the maximum tension of the candidate sling is not greater than the tension threshold corresponding to the sling model, determining the candidate sling as the sling to be installed.
Correspondingly, when the maximum tension of the candidate sling is determined to be larger than the tension threshold corresponding to the sling model, alarm information is generated.
Specifically, the maximum tension refers to the maximum tension borne by the candidate sling in the transportation process, but because the sling of different sling models has different relevant parameters such as flexibility, diameter, rigidity and weight, the tension thresholds of the slings of different sling models are different, and in order to further ensure the transportation safety, the sling with the tension threshold capable of meeting the transportation requirement should be adopted for installation.
It should be explained that the maximum tension of the candidate slings can also be relieved by adjusting the number of slings and the mounting location.
Similarly, since slings with higher pull thresholds are also typically relatively expensive, a sling that meets current transportation requirements can be identified as a candidate sling, and further consideration needs to be given to the operator if the candidate sling is selected for installation.
And 204, selecting the slings to be installed according to the safety evaluation results corresponding to all the slings.
Specifically, in order to save the transportation cost while ensuring the transportation safety, a new current sling (sling to be installed) may be selected to be installed in the determined sling to be installed in the above embodiment, and the sling model, the sling number, and the sling position in the sling information of the sling to be installed are appropriately adjusted, and the above steps are repeated until the obtained sling to be installed has higher safety and lower cost, the sling to be installed is taken as a target sling, and construction is performed according to the sling information of the target sling.
Specifically, in an embodiment, the safety assessment result can be obtained by continuously adjusting the environmental information of the target transportation position under the condition that sling information of the current sling and physical information of the goods to be transported are fixed, and the window period suitable for transportation work can be determined according to the obtained safety assessment result.
Specifically, the goods can be transported by selecting a safe window period according to the safety assessment results corresponding to different environmental information, so that the transportation risk caused by environmental factors is avoided, and the transportation safety is further improved.
It should be explained that the environmental information of the sea area has a certain correlation with the time, and the time corresponding to each environmental information can be determined according to the relevant hydrological and meteorological data, so as to determine the safe window period.
According to the sling selecting method provided by the embodiment of the application, sling information corresponding to a current sling arranged on a guide frame of a transport ship, physical information of goods to be transported and environmental information of a target transport position are obtained; the physical information comprises the weight, the gravity center position and the shape of the goods to be transported, and the environmental information comprises wind speed, wind direction, flow speed, wind wave data and surge data; the sling information includes: sling type, sling number and installation position; determining the rolling angle of the goods to be transported and the rolling angle of the guide frame according to the physical information, the environmental information and the sling information of the goods to be transported; generating a safety evaluation result according to the relation between the rolling angle of the goods to be transported and the rolling angle of the guide frame and the preset rolling angle threshold of the goods to be transported and the preset rolling angle threshold of the guide frame; and selecting the sling to install according to the safety evaluation results corresponding to all the slings. According to the sling selection method provided by the scheme, before the sling is selected and installed, the safety of the current sling is evaluated according to the physical information and the environmental information of the goods to be transported and the sling information of the current sling to be selected, and the finally selected sling is determined according to the generated evaluation result, so that the accuracy of sling selection is improved, and the safety of transportation is further guaranteed.
