Background technique

At present, ships and ocean engineering structures are mainly connected by fusion welding. The uneven local heating of steel by welding arc will inevitably lead to stress and deformation of ships and ocean engineering structures. There are many problems in the traditional pyrotechnic leveling and deformation process, such as high requirements for the experience of the operator, high uncertainty of the leveling effect, and toxic gas will be generated during the heating process, which has a great impact on the environment. There will also be safety hazards when the fuel is stored. In addition, water and fire correction has high labor intensity and poor environment, and fewer and fewer people are willing to engage in this industry.

Although the high-frequency induction heating technology has the advantages of cleanliness, high efficiency, and easy operation, it has a wide range of application prospects in the industrial field. However, the current induction heating levelers still have the following problems:

(1) The induction heater and the power supply are separated, and the induction heating coil is fixed on the mobile trolley, so that the induction coil and the power supply are generally connected through a long cable, and the loss of high-frequency current in the cable is relatively large. At the same time, it is difficult to match the capacitance and inductance of the power supply.

(2) Generally, when the distance between the induction heating coil and the steel plate is 3-4mm, the effect of electromagnetic induction is the best, but the distance between the traditional induction coil and the heating component and the steel plate will not be adjusted with the deformation of the steel plate. The efficiency of electromagnetic induction cannot be guaranteed, thus affecting the heating effect.

Beneficial effect: compared with prior art, the advantage of the present invention is:

(1) Through the integrated structural design of the intelligent heating mechanism, chiller mechanism and high-frequency power supply mechanism, the high-frequency current generated by the resonant circuit can be directly transmitted to the lifting device without long-distance cable transmission to the high-frequency transformer. The high-frequency transformer on the platform shortens the transmission distance of high-frequency high-voltage current from tens of meters to less than 1 meter, which not only reduces the manufacturing cost, but also greatly reduces the energy loss in the transmission process.

(2) The induction coil is changed from the traditional fixed type to the automatic adjustment method that can adjust the heating distance according to the different deformation degrees of the steel plate. Four ultrasonic distance sensors at different positions are used to accurately measure the distance between the induction coil and the steel plate, which is reasonable. Adjust the rotation of the lead screw servo motor to keep the induction coil parallel to the heated steel plate and control the distance between them to the distance with the highest heating efficiency. The whole process is calculated and adjusted by the controller, which improves the intelligence of the overall equipment It also improves the heating efficiency and saves electric energy; in addition, it can also heat the steel plate more uniformly, which greatly improves the heating effect.

(3) It is widely applicable. The intelligent heating mechanism of this leveler is also suitable for the induction coil in the mobile heater of the traditional split induction heating leveler. For the different size of the steel plate leveling area, the fixed lifting platform that can be used There are also two ways. If the heating area is small, the method of installing the lead screw servo motor on the axle can be adopted. At this time, the ultrasonic distance sensor is located on both sides of the axle; when the heating area is large, the distance between the two axles is relaxed, and the four lead screw servo motors And the lifting platform is located between the two axles; rational use of the two structures can improve the adjustment effect of the lifting platform.

(4) The internal high-frequency heat dissipation of the new high-frequency intelligent leveling machine of the present invention adopts the form of air cooling, and the power supply part is placed on the upper layer of the whole machine. Even if the chiller leaks water, it will not cause safety hazards to the power supply, which improves the overall safety. For the high-frequency transformer at the bottom, water cooling can be used to cool down. Since the distance between the water tank and the coaxial transformer is relatively close, the power required by the compressor pump of the chiller and the size of the water tank are much smaller than those of the split type, and it will also save money on purchases and costs compared to the split type. The cost. Compared with the traditional split-type mobile heater, the volume and quality have increased, but the human operation has been reduced. The various systems in the high-frequency induction power supply have been integrated together to form a movable whole, and the manual operation has also been cancelled. Mobile operation; the front end of the intelligent high-frequency intelligent leveling machine is equipped with a high-definition camera, which can independently heat the long-distance weld seam on the heated thin steel plate, independently identify the long-distance weld seam and make a trajectory identification, and control it after heating The working time of the servo motor to control the travel distance of the intelligent high-frequency intelligent leveler is a new type of intelligent manufacturing equipment, which will surely improve the level of intelligent manufacturing in shipyards.

A method for using the integrated high-frequency intelligent leveler according to any one of claims 1 to 8, characterized in that it comprises the following steps:

Step 1: Connect the three-phase AC socket, the integrated high-frequency intelligent leveler starts to supply power, and the main controller is turned on;

Step 2: Start the chiller mechanism to start the water cooling cycle;

Step 3: Push the integrated high-frequency intelligent leveler to the area that needs to work, start the intelligent heating mechanism, the main controller recognizes the signal through the picture sent back, and moves the induction coil to the weld position on the heated steel plate through the moving frame alignment;

Step 4: After aligning the weld seam, the main controller controls the distance sensor to continuously measure the distance between the induction coil and the steel plate, and controls the lifting component to complete the height adjustment through the feedback signal of the distance sensor, so that the induction coil reaches the heating station;

Step 5: Start the heating function after the adjustment is completed. The high-frequency alternating current is transmitted to the high-frequency transformer through the transmission pipe, and then generates a magnetic field through the induction line. The magnetic field acts on the steel plate to generate eddy currents to achieve the heating effect;

Step 6: After the heating is over, the controller moves the rack to the downward heating position and aligns it with the next weld, and repeats steps 4 and 5 to enter the next heating process until the operator presses the stop button or the image The power supply stops working when the weld seam is not recognized.
