Description

Technical Field

[0001] This utility model relates to a head cylinder, specifically a welding and adjustment device for a large nozzle on a head cylinder. Background Technology

[0002] When assembling and welding pipe ends of multiple pieces of equipment, smaller pipe ends (≤DN300) are lighter in weight (≤50kg) and can be adjusted manually. However, larger / heavier pipe end assemblies rely on workshop lifting equipment for adjustment and assembly. A workshop typically has only one large lifting device, but when multiple sets of equipment are operating simultaneously, the number of lifting devices is insufficient for simultaneous assembly. Each lifting device can only adjust one pipe end, and a single piece of equipment usually has multiple sets of pipe ends, significantly impacting installation and welding efficiency and affecting the overall equipment delivery time. The conventional method for placing pipe end assemblies is to directly weld support ribs between the flange and the main body. Adjustments during welding are inconvenient, and the welding support components must be disassembled after assembly, requiring grinding and resulting in multiple grinding points. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a welding adjustment device for a large nozzle on a head cylinder. This utility model allows for manual adjustment without the need for a crane, thus freeing up production capacity. It also eliminates the need for welding and the associated workload of dismantling welding supports and subsequent cutting and grinding.

[0004] To achieve the above technical objectives, this utility model adopts the following technical solution: a welding adjustment device for a large nozzle on a head cylinder, comprising a support base, a connector, an adjusting stud assembly, and a support column. The support base is fixedly connected to the nozzle assembly via the connector. The upper end of the adjusting stud assembly is threaded to the support base, and the lower end is threaded to the support column. An adjusting nut is provided on the adjusting stud assembly. Adjusting the height of the adjusting nut adjusts the height of the support base, thereby adjusting the height of the nozzle assembly.

[0005] The support base has a through hole for connecting to the pipe assembly with the connector, and also has a threaded hole for threaded connection with the upper end of the adjusting stud assembly.

[0006] The connector includes a gasket and a connecting bolt. The connecting bolt passes through the flange hole of the pipe assembly and the gasket and is fastened with a nut.

[0007] The connector also includes a limiting block, the outer diameter of which is adapted to the flange hole of the pipe assembly. The limiting block is built into the flange hole of the pipe assembly and has an inner hole through which the connecting bolt passes.

[0008] The adjusting stud assembly includes an adjusting stud and an adjusting nut. The upper end of the adjusting stud is threaded to the threaded hole, and the lower end is threaded to the support threaded hole of the support column. The adjusting nut is threaded to the adjusting stud and is close to the support column. The adjusting nut can be adjusted downward so that the adjusting stud can rise to a suitable position.

[0009] The adjusting stud is also provided with an upper nut and a limiting nut. The upper nut is close to the threaded hole of the support base, and the limiting nut is close to the adjusting nut.

[0010] The support column has a support threaded hole.

[0011] It also includes a horizontal and vertical level, which is placed on the nozzle assembly to indicate the levelness.

[0012] In summary, this utility model achieves the following technical effects:

[0013] Without this device, adjusting dimensions requires the use of lifting equipment, which is time-consuming and often disrupts other projects that would otherwise need to use the lifting equipment. Fixing can only be done by welding, and the supporting structure must be removed later by cutting and grinding. Dimensional adjustments cannot be made again during the welding process.

[0014] This invention allows for the adjustment of height and flatness dimensions without the need for a lifting device, thus freeing up production capacity.

[0015] This utility model uses bolts to fix both the support and the position adjustment, eliminating the need for welding and saving the work of dismantling the welded support and subsequent cutting and grinding.

[0016] This invention allows for direct observation of changes in flatness during the welding process, enabling adjustments via nuts to ensure the final dimensions meet requirements. Attached Figure Description

[0029] Example:

[0030] Figure 1 This is a cross-sectional diagram illustrating the usage of a welding adjustment device for a large nozzle on a head cylinder. For pipe assemblies that have been hoisted and spot-welded, further adjustments are difficult, and there is no effective and intuitive method for adjustment and observation during the welding process. If adjustments are desired, the time required for using the hoisting equipment must be utilized. After this device is assembled, the height and planar dimensions can be adjusted by adjusting the nuts. Furthermore, dimensions can be adjusted and controlled during the welding process to ensure the overall dimensions after welding without the need for a hoisting device.

[0031] The assembly includes a support base 1, a connector, an adjusting stud assembly (7,8), and a support column (9,10). The support base 1 is fixedly connected to the pipe assembly via the connector. The upper end of the adjusting stud assembly (7,8) is threaded to the support base 1, and the lower end is threaded to the support column (9,10). An adjusting nut is provided on the adjusting stud assembly (7,8). Adjusting the height of the adjusting nut adjusts the height of the support base 1, thereby adjusting the height of the pipe assembly.

[0032] This invention features an adjustment device that uses connectors to fix the support base to the edge of the pipe assembly. Then, adjustment stud assemblies (7,8) and support columns (9,10) are assembled. Changing the height of the adjustment stud assemblies (7,8) alters the height of the support base, thereby changing the height of the pipe assembly. The adjustment stud assemblies can be adjusted with a wrench. This invention allows for manual adjustment of the height of the pipe assembly, thus manually adjusting its levelness and fit with the end cap cylinder. It replaces the method of repeatedly lifting and lowering the pipe assembly using a crane. This invention eliminates the need for welding to the pipe assembly and allows for dimensional adjustment without a lifting device during the welding process; a conventional wrench suffices. This efficiently assists in welding the pipe assembly and allows for reuse, significantly reducing the efficiency of the lifting device and accelerating the overall equipment manufacturing process. After welding, there is no need to disassemble or grind the traditional support device.

[0033] Figure 2 This is a cross-sectional view of the support base. Figure 3 This is a top view of the support base. The support base 1 has a through hole 101 for connecting with the connector to the pipe assembly, and also has a threaded hole 102 for threaded connection with the upper end of the adjusting stud assembly.

[0034] Combination Figure 1 The connector includes a gasket 3 and a connecting bolt 4. The connecting bolt 4 passes through the flange hole of the pipe assembly and the gasket 3 and is fastened with a nut.

[0035] Figure 4 This is a cross-sectional schematic diagram of the limiting block. The connecting component also includes a limiting block 2. The outer diameter of the limiting block 2 is adapted to the flange hole of the pipe assembly. The limiting block 2 is built into the flange hole of the pipe assembly. The limiting block 2 has an inner hole, and the connecting bolt 4 passes through the inner hole.

[0036] Combination Figure 1 The adjusting stud assembly (7,8) includes an adjusting stud and an adjusting nut. The upper end of the adjusting stud is threaded to the threaded hole 102, and the lower end is threaded to the support threaded hole of the support column (9,10). The adjusting nut is threaded to the adjusting stud and is close to the support column (9,10). The adjusting nut can be adjusted downward so that the adjusting stud can be raised to a suitable position.

[0037] In the initial stage, the adjusting stud assembly (7,8) is threaded onto the support column (9,10). The height of the nozzle assembly is adjusted to be low beforehand. After all the parts are assembled, the adjusting nut is gradually lowered, allowing the adjusting stud to rise gradually, so that the entire nozzle assembly gradually rises until it reaches the appropriate position.

[0038] The adjusting stud is also provided with an upper nut and a limiting nut. The upper nut is close to the threaded hole 102 of the support base 1, and the limiting nut is close to the adjusting nut.

[0039] Figure 1 Two sets of adjustment devices are shown, with the nozzle assembly located in the middle. Since the nozzle assembly is to be installed on the inclined surface of the head cylinder, the left side is the longer adjustment device and the right side is the shorter adjustment device.

[0040] Figure 5 This is a schematic diagram of a support column, which has a support threaded hole.

[0041] Figure 1The left side shows the long adjusting stud assembly 7 and the long support column 9, which work together. The right side shows the short adjusting stud assembly 8 and the short support column 10, which also work together. The long adjusting stud assembly 7 and the short adjusting stud assembly 8 have the same structure, only their lengths differ. Similarly, the long support column 9 and the short support column 10 have the same structure, only their lengths differ.

[0042] It also includes horizontal and vertical levels (5,6), which are placed on the nozzle assembly to indicate the levelness.

[0043] Figure 6 yes Figure 1 The top view includes at least four sets of welding adjustment devices for larger nozzles on the end cap cylinder.

[0044] At least four sets of adjustment devices are evenly distributed around the circumference of the nozzle assembly.

[0045] The height of the four sets of adjusting studs is adapted to the distance between the pipe assembly and the end cap cylinder, and the height of the four sets of support columns is adapted to the distance between the pipe assembly and the end cap cylinder.

[0046] This invention employs a convenient adjustment method, utilizing widened support bases with multi-point circumferential support. Each support base is secured to the equipment body via two sets of long and short support devices, thus ensuring the overall dimensions of the supported pipe base. During the welding process, dimensions are adjusted in a timely manner by observing with a level, thereby controlling the final dimensions after welding.

[0047] The support base and the required adjusting pipe assembly are assembled via flange bolt holes and limit blocks. After assembly, it is then assembled with the adjusting studs and support devices. A support device of appropriate length is selected and assembled with the adjusting studs. Four pieces are evenly distributed around the pipe assembly. A simple level is placed horizontally and vertically on top of the pipe assembly. The installation dimensions and overall flatness of the pipe base are controlled by adjusting the nuts. During welding, carefully observe the level and adjust the nut position to control welding deformation.

[0048] Work process:

[0049] Collect the bolt hole dimensions and support span corresponding to the pipe assembly of the required support device.

[0050] Fabricate limiting blocks and long and short supports. The limiting blocks are fabricated according to the bolt hole sizes of different pipe openings, and the long and short supports are fabricated according to the required span of the pipe openings, selecting adjustable sizes.

[0051] Pre-assemble the support base and the pipe assembly, and assemble them evenly in 4 or 8 groups around the circumference.

[0052] Hoist the pipe assembly to the installation position.

[0053] Assemble the remaining components of the support device and adjust the circumferential support height to ensure that it meets the assembly dimension requirements.

[0054] Spot weld the pipe fittings to the equipment welds and release the lifting device.

[0055] When welding pipe fittings and equipment, pay attention to the level during the process and adjust the support height using nuts to ensure that the final welded dimensions meet the requirements.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
