Specific embodiments

[0025] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. 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.

[0026] Specific embodiment 1: Please refer to Figures 1-5 , the present invention provides a technical solution: a steel plate leveling device for ship assembly, including a bottom plate 1, a support roller assembly 4 installed on the bottom plate 1, and a pressure roller assembly 3 installed above the support roller assembly 4. The side of the support roller assembly 4 is connected to the drive gear 61 of the reduction box 6 through a gear, and a drive motor 2 is connected to the side of the reduction box 6. A limit frame 5 is fixed on the bottom plate 1 on the side of the drive motor 2;

[0027] The support roller assembly 4 includes two groups of support rollers 41 and two groups of support seats 45 installed on both sides of the support rollers 41. Driven gears 42 and support roller gears 44 are respectively installed at the left ends of the two groups of support rollers 41. The driven gear 42 and the support roller gear 44 are meshed and driven through an intermediate gear 43, and hinge frames 46 are provided on the sides of the support seats 45;

[0028] The pressure roller assembly 3 includes a pressure roller 31, a right pressure roller adjusting mechanism 32, and a left pressure roller adjusting mechanism 33. The left side of the pressure roller 31 is installed on the inner slider of the left pressure roller adjusting mechanism 33. The end shaft of the pressure roller 31 extending out of the left pressure roller adjusting mechanism 33 extends deep into the limiting frame 5. The right end shaft of the pressure roller 31 is installed on the inner slider of the right pressure roller adjusting mechanism 32. The lower end of the right pressure roller adjusting mechanism 32 is connected to the hinge frame 46 through a pin rod 7.

[0029] During use, when the ship repairs a single plate and levels the plate, the drive motor 2 is powered on. The operation of the drive motor 2 drives the reduction gearbox 6 to rotate, and then drives the support roller assembly 4 to rotate. The plate is placed into the gap between the pressure roller assembly 3 and the support roller assembly 4. The support roller assembly 4 operates to convey the plate forward for pressing. When the thickness of the plate changes, the drive cylinders on the left pressure roller adjusting mechanism 33 and the right pressure roller adjusting mechanism 32 can be operated to adjust the gap width between the pressure roller assembly 3 and the support roller assembly 4.

[0030] When fixing the plate for leveling, the pin rod 7 is disassembled, the pressure roller assembly 3 is removed, and the plate is directly inserted between the pressure roller assembly 3 and the support roller assembly 4. The power is turned on, and the drive motor 2 drives the support roller assembly 4 to rotate, so that the device moves on the plate to level the plate.

[0031] When the back of the plate on the ship is not the same, the pin rod 7 on one side is disassembled, and by adjusting the length of the pull rod 8, the gap between the pressure roller assembly 3 and the support roller assembly 4 is adjusted to form a wedge-shaped structure. The plate is placed in, and the device is powered on and operated for leveling work.

[0032] Specific Embodiment 2: The difference technical feature between this embodiment and Embodiment 1 is that the right pressure roller adjusting mechanism 32 includes a mounting frame 321 in a portal structure, a support 323 welded and fixed in the middle of the mounting frame 321, a lifting drive cylinder 324 bolted to the upper end of the support 323, and the output rod of the lifting drive cylinder 324 is connected to the slider 322. The structure of the right pressure roller adjusting mechanism 32 is the same as that of the left pressure roller adjusting mechanism 33. Convex blocks are arranged on the side surfaces of the sliders 322, and slide rails are arranged on the inner side of the mounting frame 321 for the convex blocks on the side surfaces of the sliders 322 to slide up and down inside the slide rails, achieving a guiding effect. The connection between the slider 322 and the lifting drive cylinder 324 can be fixed by bolts. A bearing is installed at the connection between the slider 322 and the pressure roller 31. The slider 322 is a T-shaped bearing seat, and the slider 322 moves left, right, up, and down under the action of the lifting drive cylinder 324.

[0033] Specific Embodiment 3: The difference technical feature between this embodiment and Embodiment 1 is that: an articulated seat 11 is provided below the right bottom of the bottom plate 1, and a pull rod 8 is articulated outside the articulated seat 11, and the upper end of the pull rod 8 is articulated with the support outside the support seat 323; the pull rod 8 is one of an electric push rod, a cylinder hydraulic cylinder, and a threaded telescopic rod, and the adjustment method can be selected according to requirements.

[0034] Specific Embodiment 4: The difference technical feature between this embodiment and Embodiment 1 is that: at least two groups of support roller assemblies 4 are installed on the bottom plate 1, and a linkage gear 47 is installed on the end of one of the support rollers 41 on the support roller assembly 4. The linkage gears 47 between the multiple groups of support roller assemblies 4 are connected, and a pressure roller assembly 3 is installed on each of the multiple groups of support roller assemblies 4. The multiple groups of support roller assemblies 4 can be driven by an automatic drive motor. By increasing the support roller assemblies 4, the leveling effect is better; at least one pressure roller 31 is installed on the pressure roller assembly 3, and the pressure roller 31 is installed at the gap position between two support rollers 41;

[0035] The support seat 45 and the articulated frames 46 on both sides are integrally welded, and the articulated frames 46 form a U-shaped structure. At the same time, a pin rod 7 is inserted into the through hole in the middle of the articulated frame 46, and the two pin rods 7 installed on both sides of the support seat 45 are coaxial. The right pressure roller adjusting mechanism 32 and the left pressure roller adjusting mechanism 31 can rotate independently around the pin rod 7.

[0036] Specific Embodiment 5: The difference technical feature between this embodiment and Embodiment 1 is that: the support seat 45 installed below the right pressure roller adjusting mechanism 32 is a detachable structure on the bottom plate 1. The bearing in the device is prone to damage under force, and the detachable support seat 45 is more convenient for replacement, and the right pressure roller adjusting mechanism 32 can rotate around the pin rod 7 installed below.

[0037] Specific Embodiment 6: The difference technical feature between this embodiment and Embodiment 1 is that: the limit frame 5 includes a bracket 51 with a portal structure and an adjusting bolt 52 screwed on the top of the bracket 51, and the lower end of the adjusting bolt 52 corresponds to the shaft rod of the roller end of the pressure roller 31. During the process of the pull rod 8 adjusting the inclination angle of the pressure roller assembly 3, the force on the pressure roller 31 can be supported by rotating the adjusting bolt 52.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
