Description

Technical Field

[0001] This utility model relates to the field of heating process equipment, and more specifically, to a process equipment for preheating and post-heating of the weld seam of the thick plate of the container ship hatch coaming. Background Technology

[0002] In the construction of thick plate butt welds around the container ship hold, preheating before welding and post-weld heat treatment are crucial steps to ensure weld quality. Currently, existing technologies mainly employ two heating methods: one is to use ceramic electric heating elements, which requires manual handling and laying of a large number of heating elements on the weldment surface, wasting manpower and material resources, and this contact heating method often interferes with the welding process; the other is to use a manual flame gun for heating, which easily leads to uneven heating of the weld and poor preheating effect.

[0003] Furthermore, in existing processes, preheating and post-heating are typically achieved through two separate steps or equipment: preheating and welding are performed first, followed by post-heating via a heat treatment furnace or by re-laying electric heating elements. This method requires cumbersome process transfers, significantly increasing auxiliary welding time and reducing welding production efficiency.

[0004] Therefore, there is an urgent need for a process device that can solve the problems of high labor costs, uneven heating, avoid interference with welding construction, and efficiently balance preheating and post-heating. Utility Model Content

[0005] To address the aforementioned technical problems, a process device for preheating and post-heating of weld seams in thick plates at the hatches of container ships is provided. This invention utilizes a mobile platform equipped with an adjustable induction heater and positioning columns to achieve non-contact preheating, post-heating, and deformation-preventing fixation of the weld seams.

[0006] To achieve the above objectives, this utility model provides a process device for preheating and post-heating of the weld seam of the thick plate of the container ship hatch coaming, including: a support plate, a brushless motor drive wheel, a positioning column and a support column;

[0007] The brushless motor drive wheel is fixedly installed below the support plate, and the positioning column and support column are vertically fixedly installed above the support plate;

[0008] A worm gear lift is fixedly installed on the support column. A lead screw is vertically inserted inside the worm gear lift. A fixing shim is fixedly connected above the lead screw. A heating working platform is horizontally fixedly connected above the fixing shim.

[0009] The heating work platform has a square through hole in the middle. A slide rail is fixedly installed inside the square through hole along its length. The slide rail is slidably connected to the induction heater through a bracket. The induction heater is located below the heating work platform.

[0010] The positioning column is equipped with tightening bolts for clamping the steel plate.

[0011] Furthermore, it also includes a stepper motor, the output shaft of which is connected to the lead screw on the worm gear jack to drive the lead screw to rotate.

[0012] Furthermore, the support plate is machined with a positioning groove, the positioning column is located in the positioning groove, and can move along the positioning groove.

[0013] Furthermore, it also includes a servo driver, which is electrically connected to the stepper motor and is used to control the operation of the stepper motor.

[0014] Furthermore, the number of brushless motor drive wheels is four, which are fixedly installed at the four corners below the support plate.

[0015] Furthermore, one end of the bracket is slidably mounted on the slide rail, and the other end of the bracket is fixedly connected to the induction heater. By moving the bracket, the horizontal position of the induction heater within the square through hole range can be adjusted.

[0016] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] 1. The present invention provides a process device for preheating and postheating of the weld seam of the thick plate of the container ship hatch coaming.

[0018] 2. The present invention provides a process device for preheating and postheating of the weld seam of the thick plate of the container ship hatch coaming. By processing the positioning groove on the support plate, the lateral movement adjustment of the positioning column is realized, so that the device can adapt to the positioning of steel plates of different widths; at the same time, with the tightening bolts to clamp the steel plate, the welding deformation generated in the subsequent welding process can be effectively prevented, and the welding quality can be guaranteed.

[0019] 3. The present invention provides a process device for preheating and postheating of the weld seam of the thick plate of container ship hatch opening.

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0030] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description.

Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0033] like Figures 1 to 4 As shown, this utility model provides a process device for preheating and postheating of the weld seam of the thick plate of the container ship hatch coaming, including: a support plate 1, a brushless motor drive wheel 2, a positioning column 3 and a support column 4;

[0034] Four brushless motor drive wheels 2 are fixedly installed at the four corners below the support plate 1 to drive the entire device. Positioning columns 3 and support columns 4 are vertically fixedly installed above the support plate 1. Positioning grooves 9 are machined on the support plate 1, and the positioning columns 3 are located within these grooves and can move laterally along them to accommodate steel plates 17 of different widths. Tightening bolts 16 are threaded through the positioning columns 3 to clamp the steel plates 17.

[0035] This embodiment constructs the overall basic framework of the device. The brushless motor drives the wheel 2 to achieve automatic movement of the device without manual handling. The lifting of the heating components is achieved through the cooperation of the support column 4 and the worm gear lift 12. Non-contact heating is achieved through the induction heater 8, which integrates preheating and post-heating functions and solves the problem of interference welding construction caused by traditional contact heating.

[0036] For lifting and adjustment, a worm gear lift 12 is fixedly installed on the support column 4, and a lead screw 13 passes through the inside of the worm gear lift 12. A fixing pad 14 is fixedly connected above the lead screw 13, and a heating work platform 5 is horizontally fixedly connected above the fixing pad 14. The device is also equipped with a servo driver 10 and a stepper motor 11. The servo driver 10 is electrically connected to the stepper motor 11 to control the operation of the stepper motor 11; the output shaft of the stepper motor 11 is drively connected to the lead screw 13 on the worm gear lift 12 to drive the lead screw 13 to rotate, thereby driving the heating work platform 5 to lift and lower.

[0037] The stepper motor 11, in conjunction with the worm gear jack 12 and lead screw 13, enables automated and precise adjustment of the heating platform height. This ensures that the induction heater 8 can accurately approach the weld surface of the steel plate 17 for efficient heating, while quickly rising to avoid obstruction when heating is not required, facilitating subsequent welding operations.

[0038] Regarding the heating components, a square through-hole 6 is machined in the center of the heating work platform 5, and a slide rail 7 is fixedly installed inside the square through-hole 6 along its length. A bracket 15 is mounted on the slide rail 7, with one end of the bracket 15 slidably mounted on the slide rail 7 and the other end fixedly connected to the induction heater 8. The induction heater 8 is located below the heating work platform 5. By moving the bracket 15, the horizontal position of the induction heater 8 within the square through-hole 6 can be adjusted to align it with the weld seam.

[0039] The specific steps for preheating and post-heating of the thick weld seams of container ship hatch coaming plates using the above-mentioned device are as follows:

[0040] S1. Start the four brushless motor drive wheels 2 fixedly installed below the support plate 1, driving the support plate 1 and the entire device to move. After moving into position, the support plate 1 is positioned on both sides of the steel plate 17 to be welded, and the heating working platform 5 is directly above the steel plate 17.

[0041] S2. According to the specific location of the weld, move the fine-tuning bracket 15 along the slide rail 7 in the square through hole 6, thereby driving the induction heater 8 to move horizontally until the induction heater 8 is accurately aligned with the weld that needs to be preheated.

[0042] S3. The stepper motor 11 is controlled to rotate by the servo driver 10. The stepper motor 11 drives the lead screw 13 inside the worm gear jack 12 to rotate, causing the upper heating platform 5 to descend until the induction heater 8 is close to the weld surface of the steel plate 17. The induction heater 8 is then turned on to preheat the weld in a non-contact manner.

[0043] S4. After preheating, the stepper motor 11 is reversed again by the servo driver 10, which drives the lead screw 13 to raise the heating platform 5 and the induction heater 8. Then, the positioning column 3 is moved to the appropriate position along the positioning groove 9, and the tightening bolt 16 is rotated to clamp the steel plate 17 to prevent deformation during welding. Then, the welding operation of the steel plate 17 is carried out.

[0044] S5. After welding is completed, repeat the operation in step three. Control the heating platform 5 to descend, so that the induction heater 8 is brought close to the completed weld again for post-weld heat treatment.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
