Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, in particular to a freely adjustable device for assembling and welding marine stainless steel pipes. Background Art

[0002] During shipbuilding, the assembly and welding of stainless steel pipes is a critical and laborious task. Traditional methods of stainless steel pipe assembly often have numerous drawbacks. For example, workers typically use simple supports to place the stainless steel pipes at a certain height for assembly and welding. However, due to the fixed height, traditional assembly methods cannot be flexibly adjusted to meet different construction requirements. This can cause workers to maintain uncomfortable postures for extended periods of time, significantly affecting work efficiency and welding quality, while also increasing labor intensity.

[0003] During handling and assembly, conventional supports can easily scratch the smooth surface of stainless steel pipes, affecting their appearance and corrosion resistance. Furthermore, existing assembly equipment is complex, costly, and difficult to adjust, making it difficult to meet the demand for efficient and cost-effective assembly equipment during shipbuilding. Summary of the Invention

[0004] The purpose of the present invention is to provide a freely adjustable device for assembling and welding marine stainless steel pipes, which can freely adjust the height to adapt to different assembly and welding requirements, thereby improving work efficiency and welding quality; at the same time, by installing wear-resistant rubber at the contact parts, the stainless steel pipes are effectively prevented from being damaged during the assembly process; in addition, the device has a simple structure, is easy to manufacture and adjust, is low-cost, and can be used in combination with multiple devices, further improving its applicability.

[0005] This application proposes a freely adjustable device for assembling and welding marine stainless steel pipes, including an anti-tilt device, a support column, a stopper, a lifting structure, and a bracket structure;

[0006] There are at least three sets of anti-tilt devices, which are symmetrically distributed and installed on the support columns. The anti-tilt devices can ensure the stability of the freely adjustable device during operation;

[0007] The lifting structure is installed on the support column, and the bracket structure is fixedly installed on the top of the lifting structure. The lifting structure can drive the bracket structure to move up and down, and the lifting structure can be limited by the stop device to move up and down;

[0008] The lifting structure includes a rotating screw and a threaded seat. The threaded seat is installed on the support column, and the threaded seat can rotate freely compared to the support column. The rotating screw is threadedly connected to the threaded seat, so that when the threaded seat rotates, it can drive the rotating screw to move up and down.

[0009] Furthermore, the bracket structure includes a bracket base plate and a V-shaped bracket. The bracket base plate is fixedly mounted on the top of the rotating screw. The V-shaped bracket is fixedly mounted on the bracket base plate. Wear-resistant rubber is installed on the surface of the V-shaped bracket.

[0010] Furthermore, a bracket elbow plate is fixedly installed between the bracket base plate and the V-shaped bracket.

[0011] Furthermore, it also includes a rotating handle, which is fixedly mounted on the threaded seat.

[0012] Furthermore, the anti-roll device includes an anti-roll plate and a fixed plate. One end of the anti-roll plate is fixedly installed on the support column, and the other end is fixedly installed with a pad. One end of the fixed plate is fixedly connected to the anti-roll plate, and the other end is fixedly connected to the support column.

[0013] Furthermore, the stopping device is a threaded hole provided on the threaded seat and a bolt matched therewith.

[0014] Furthermore, the inclined surfaces on both sides of the V-shaped bracket have a certain curvature to adapt to the circular arc surface of the stainless steel pipe.

[0015] The advantages and positive effects of the present invention are:

[0016] 1. Height Adjustability: The present invention achieves free height adjustment of the assembly device through the screw structure, which can meet the requirements of the stainless steel pipe assembly height in different construction scenarios. Whether performing high-altitude assembly on a higher working platform or welding operations on the lower bottom of a cabin, the operator can easily adjust the height of the device by rotating the rotary handle to place the stainless steel pipe in the most suitable operating position, greatly improving work efficiency and welding quality, while also reducing the labor intensity of workers.

[0017] 2. Anti-damage function: The wear-resistant rubber attached to the surface of the V-shaped bracket effectively solves the problem of stainless steel pipes being easily scratched during the assembly process; the wear-resistant rubber can closely fit the surface of the stainless steel pipe, providing good support while avoiding direct contact between metal and metal, thereby protecting the surface quality of the stainless steel pipe, reducing quality problems caused by surface damage, and improving the overall construction quality of the ship;

[0018] 3. Structural simplicity: The main structure of the present invention is simple and clear, the processing and manufacturing process of the components are relatively simple, and the required raw materials are easy to obtain. Moreover, the assembly and disassembly process of the device is also very convenient, and does not require professional tools and complex operating skills, which reduces production costs and maintenance difficulties. In addition, due to its simple structure, operators can more easily understand and master the use of the device, and can quickly get started, further improving work efficiency.

[0019] 4. Advantages of combined use: This device can be used in combination of 2 to 3 devices, which greatly expands its application range. By flexibly combining multiple devices, it can adapt to the assembly needs of stainless steel pipes of different lengths, diameters and shapes. In the actual shipbuilding process, it can cope with various complex assembly scenarios, improve the versatility and practicality of the device, and provide a more convenient and efficient assembly solution for shipbuilding work.

[0025] In order to make the purpose, technical solutions and advantages of the implementation of the present invention clearer, the technical solutions in the embodiments of the present invention will be described in more detail below with reference to the drawings in the embodiments of the present invention. In the drawings, the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The described embodiments are part of the embodiments of the present invention, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present invention, and should not be understood as limiting the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, this embodiment provides a freely adjustable device for assembling and welding marine stainless steel pipes, including an anti-tilt device, a support column 4, a stopper 5, a lifting structure, and a bracket structure;

[0028] There are at least three sets of anti-tilt devices, which are symmetrically distributed and installed on the support columns. The anti-tilt devices can ensure the stability of the freely adjustable device during operation;

[0029] The lifting structure is installed on the support column, and the bracket structure is fixedly installed on the top of the lifting structure. The lifting structure can drive the bracket structure to move up and down, and the lifting structure can be limited by the stop device to move up and down;

[0030] The lifting structure includes a rotating screw 6 and a threaded seat 8. The threaded seat is installed on the support column, and the threaded seat can rotate freely compared to the support column. The rotating screw is threadedly connected to the threaded seat, so that when the threaded seat rotates, it can drive the rotating screw to move up and down. It also includes a rotating handle 9, which is fixedly installed on the threaded seat. The lifting structure realizes the free adjustment of the height of the assembly device, which can meet the requirements of the assembly height of stainless steel pipes in different construction scenarios. It should be noted that the stopping device ⑸ is a threaded hole set on the threaded seat and a bolt matching it.

[0031] The bracket structure includes a bracket base plate 7 and a V-shaped bracket 11. The bracket base plate 7 is fixedly mounted on the top of the rotating screw, and the V-shaped bracket is fixedly mounted on the bracket base plate. Wear-resistant rubber 12 is installed on the surface of the V-shaped bracket 11. The inclined surfaces on both sides of the V-shaped bracket 11 have a certain curvature to adapt to the circular arc surface of the stainless steel pipe; a bracket elbow plate 10 is fixedly mounted between the bracket base plate 7 and the V-shaped bracket 11.

[0032] The anti-roll device includes an anti-roll plate 2 and a fixed plate 3. One end of the anti-roll plate 2 is fixedly installed on the support column, and the other end is fixedly installed on the pad 1. One end of the fixed plate is fixedly connected to the anti-roll plate, and the other end is fixedly connected to the support column; the anti-roll device is inclined, one end of which is connected to the support column, and the other end is in contact with the support surface.

[0033] As an example, in this embodiment, when making a support column: select a thick-walled steel pipe of appropriate specifications, cut and process it according to the designed length to ensure the verticality and dimensional accuracy of the support column; when making an anti-tilt device: weld and assemble the anti-tilt plate 2, the fixing plate 3 and the pad 1 to ensure a firm connection, and then weld the assembled anti-tilt device to the appropriate position at the bottom of the support column; when making a stopping device: prepare bolts and nuts of corresponding specifications for subsequent fixing of the rotating device; when making a lifting structure: process the rotating screw 6 and the threaded seat 8 to ensure the thread matching accuracy, and weld the rotating handle 9 to the threaded seat 8 so that it can rotate flexibly; when making a bracket structure: assemble the V-shaped bracket 11, the wear-resistant rubber 12, the bracket base plate 7 and the bracket elbow plate 10, first weld the V-shaped bracket 11 to the bracket base plate 7, and weld the bracket elbow plate 10 to a suitable position between the two to increase the structural strength, and then weld the bracket structure to the rotating screw 6 to make it a whole, and finally stick the wear-resistant rubber 12 to the inner side of the V-shaped bracket 11.

[0034] Finally, assemble all the components as a whole: screw the rotating screw 6 into the threaded seat 8, connect the threaded seat 8 to the support column 4 without welding to ensure flexible rotation, and at the same time connect the anti-tilt device to the support column 4 to complete the production of the entire device.

[0035] When using this device, select 2-3 devices according to the length and assembly requirements of the marine stainless steel pipe, and arrange them reasonably in the workplace; place the device on a stable ground, and ensure that the pad of the anti-tilt device is in full contact with the ground to ensure the stability of the device; for stainless steel pipes that need to be assembled and welded, place them on a V-shaped bracket and protect them with wear-resistant rubber; according to the assembly height requirements of the stainless steel pipe, turn the rotating handle to rotate the threaded seat on the screw, thereby driving the bracket structure to rise or fall, and adjust the height of the stainless steel pipe to the appropriate position; when the height adjustment is completed, use the bolts and nuts of the stop device to fix the upgrade structure to prevent it from displacement during the assembly and welding process; after welding is completed, loosen the stop device, lower the bracket structure by rotating the handle, remove the welded stainless steel pipe, and complete the entire assembly and welding process.

[0036] It should be noted that when it is necessary to assemble and weld marine stainless steel pipes, first place 2 to 3 of these devices in the appropriate position, use the lifting structure to adjust the bracket structure into place in advance, and then fine-tune the height after the steel pipe is placed. Then place the stainless steel pipe on the bracket structure. The V-shaped bracket and wear-resistant rubber work together to provide stable support for the stainless steel pipe and prevent its surface from being damaged. According to the height of the stainless steel pipe, turn the rotating handle to drive the threaded seat to rotate on the rotating screw. Since the rotating screw is integrated with the bracket structure, the bracket structure can be raised and lowered. Adjust the bracket structure to the appropriate height and then fix it with the stop device. During the entire assembly and welding process, the anti-tilt device always maintains the stability of the device to prevent it from tilting.

[0037] When using this device for construction, 2 to 3 devices can be combined and used, greatly expanding its application range. By flexibly combining multiple devices, it can meet the needs of assembling stainless steel pipes of different lengths, diameters and shapes.

[0038] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the above embodiments, or that some of the technical features may be replaced with equivalents; such modifications or replacements do not deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
