Description

Technical Field

[0001] This utility model belongs to the field of support tooling technology, specifically relating to a boiler header adjustment support device. Background Technology

[0002] During the welding of boiler headers and the storage and transportation of boiler headers, the structural characteristics of the bottom support base cannot restrict the degree of freedom of rotation along the axis, which leads to safety and quality problems such as header tipping over during welding, storage and transportation.

[0003] The current solution involves welding multiple steel frames to restrict the axial roll of the container. However, this method requires welding different steel frames for each container product, which is time-consuming, labor-intensive, material-intensive, and lacks versatility. Utility Model Content

[0004] To address the current problem of boiler headers being unable to be flexibly adjusted and supported during welding and transportation, this utility model provides a boiler header adjustment and support device.

[0005] The embodiments of this utility model are achieved through the following technical solutions:

[0006] A boiler header adjustment support device includes a base and a support member. The support member is connected to the base via an adjustment mechanism. The support member includes a column panel for limiting the header. The adjustment mechanism is used to drive the support member to rise and / or swing.

[0007] This support device allows for free adjustment of the support height and is suitable for boiler headers of various sizes. It can be used during the transportation and welding of boiler headers, eliminating the need for steel frame welding. This saves welding materials, as well as the time and manpower required for welding steel frames, making the process more convenient.

[0008] In some technical solutions of this utility model, the aforementioned support member further includes a horizontal plate connected to the side of the column panel away from the header, and a stiffening plate is provided between the horizontal plate and the column panel. The stiffening plate strengthens the support strength and improves the reliability of the support device. At the same time, the use of three thin plates to support the header reduces the steel cost and overall weight of the support device, further improving the lightweight mobility of the support fixture.

[0009] In some technical solutions of this utility model, the adjusting end of the adjusting mechanism is provided with a lifting plate, the lifting plate is provided with a first positioning hole and a second positioning hole, and the support member is provided with a first positioning post and a second positioning post respectively on the side away from the header corresponding to the first positioning hole and the second positioning hole. The first positioning post and the second positioning post are equipped with limiting members to prevent the positioning post from disengaging from the corresponding positioning hole.

[0010] This design makes the connection between the support and the adjustment mechanism detachable, allowing personnel to replace the support with one that is more suitable for the size range of the actual container, thereby further expanding the applicability of the support device.

[0011] In some technical solutions of this utility model, the aforementioned limiting member includes a pin, one end of which can pass through the first positioning post and the second positioning post in sequence, and the other end of the pin is provided with a positioning rod, and the first positioning post is provided with a locking groove for restricting the movement of the positioning rod.

[0012] This design method allows for the rapid replacement of different models of support devices, further improving the replaceability of support fixtures and achieving the effect of easy installation, disassembly, replacement, and relocation.

[0013] In some technical solutions of this utility model, the above-mentioned adjustment mechanism includes a first lifting component and a second lifting component spaced apart on the base, and the two lifting components can independently adjust their lifting height.

[0014] This design is flexible and allows for easy adjustment of the boiler header position, which in turn assists in the welding of the header; and as the number of lifting components increases, the accuracy of the swing becomes higher.

[0015] In some technical solutions of this utility model, the first lifting component and the second lifting mechanism have the same structure, both including a pair of support cylinders on the base, a lifting screw passing through the support cylinder, a rotating nut that is driven and cooperates with the lifting screw on the support cylinder, and the lifting end of the lifting screw is connected to the support member.

[0016] This design achieves lifting and lowering through rotation, making it suitable for containers that need to be raised and lowered to different heights, thus satisfying the versatility of the support device.

[0017] In some technical solutions of this utility model, the above-mentioned rotating nut is provided with a pair of operating handles on the ring side.

[0018] The operating handle adopts the lever principle mentioned above, which allows personnel to turn the rotating nut with less effort and also meets the need for manual lifting and lowering control, making the use of the support device more convenient.

[0019] In some technical solutions of this utility model, the first lifting component and the second lifting mechanism have the same structure, both being hydraulic cylinders.

[0020] The support device in this design can support larger weight containers, and the adjustment of the container position will be more precise.

[0021] In some technical solutions of this utility model, the base includes two double I-beam steel structure seats, and the first lifting component and the second lifting component are respectively disposed on the two double I-beam steel structure seats.

[0022] The double H-beam steel structure base is made of multiple steel plates welded together, which enhances the load-bearing strength of the base at the lowest possible cost, while also having the advantages of good stability and easy processing.

[0023] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0024] The support device incorporates an adjustment mechanism in the base and support components. Combined with the column panel of the support components, this allows the support device to be used with boiler headers at different pipe positions. It also enables the adjustment of the boiler header position, facilitating the welding of the boiler header. Attached Figure Description

[0034] Example

[0035] Please refer to Figures 1-3 A boiler header adjustment support device includes a base 1 and a support member 2. The support member 2 is connected to the base 1 through an adjustment mechanism 4. The support member 2 includes a column panel 3 for limiting the header. The adjustment mechanism 4 is used to drive the support member 2 to rise and / or swing.

[0036] The principle of this adjustable support device is as follows: A column panel 3 of one size is suitable for multiple headers of similar sizes, wherein half of the perimeter of the cross-section of the header is less than the guideline of the column surface on the upper side of the column panel 3. In use, for header products with different pipe heights, the adjusting mechanism 4 is activated. The adjusting mechanism 4 lowers the support member 2 and places it at the lower end of the boiler header. Then, the adjusting mechanism 4 raises the support member 2, and the column panel 3 of the support member 2 gradually contacts the header. The adjusting mechanism 4 then causes the support member 2 to swing, making the column panel 3 fit against the header. The adjusting mechanism 4 continues to raise the support member 2, and the height of the upward movement varies depending on the header specifications. Personnel can make corresponding adjustments according to the actual situation to complete the support of the header. When the header needs to be welded, but the header's position is inconvenient for welding, the adjusting mechanism 4 can, as needed, cause the support member 2 to swing. The header, which is in contact with the column panel 3 of the support member 2, swings along with the support member 2, thereby changing its position to facilitate welding. This support device allows for free adjustment of the support height and is suitable for boiler headers of various sizes. It can be used during the transportation and welding of boiler headers, eliminating the need for steel frame welding. This saves welding materials, as well as the time and manpower required for welding steel frames, making the process more convenient.

[0037] In a preferred embodiment, the support member 2 further includes a horizontal plate 6 connected to the side of the column panel 3 away from the header, and a stiffening plate 7 is provided between the horizontal plate 6 and the column panel 3.

[0038] In the above embodiment, the column panel 3, stiffening plate 7 and cross plate 6 are connected by welding; the stiffening plate 7 strengthens the support strength and improves the reliability of the support device. At the same time, the use of three thin plates to support the header reduces the steel cost and overall weight of the support device, and further improves the lightweight mobility of the support fixture.

[0039] In a preferred embodiment, the adjusting end of the adjusting mechanism 4 is provided with a lifting plate 13, the lifting plate 13 is provided with a first positioning hole 14 and a second positioning hole 15, the support member 2 is provided with a first positioning post 16 and a second positioning post 17 respectively on the side away from the header corresponding to the first positioning hole 14 and the second positioning hole 15, and a limiting member 18 is provided between the first positioning post 16 and the second positioning post 17 to limit the two from disengaging from the first positioning hole 14 and the second positioning hole 15.

[0040] In the above embodiments, one type of support device can be applied to multiple headers of similar models. When half of the perimeter of the header's cross-section is greater than the guideline of the column surface on the upper side of the column panel 3, it is necessary to replace it with a different type of support member 2. When replacing the support member 2, the limiting member 18 is removed from between the first positioning hole 14 and the second positioning hole 15 (for example, the limiting member 18 is a limiting post, and the two ends of the limiting post are respectively welded to the first positioning post 16 and the second positioning post 17. When it needs to be removed, the two ends of the limiting member 18 can be cut off). Then, the support member 2 is moved so that the first positioning post 16 and the second positioning post 17 are aligned. 7. The support member 2 is disengaged from the first positioning hole 14 and the second positioning hole 15 respectively. The first positioning post 16 and the second positioning post 17 corresponding to the new size support member 2 are passed through the first positioning hole 14 and the second positioning hole 15 respectively. Then, the corresponding first positioning post 16 and the second positioning post 17 are connected by limiting posts. In addition, the number of lifting plates 13, the number of first positioning holes 14, the number of second positioning holes 15, the number of first positioning posts 16, the number of second positioning posts 17 and the number of limiting posts 18 can be multiple and correspond one-to-one. This design can further expand the application range of the support device.

[0041] In a preferred embodiment, the limiting member 18 includes a pin 19, one end of which passes sequentially through the first positioning post 16 and the second positioning post 17, and the other end of the pin 19 is provided with a positioning rod 20. The first positioning post 16 has a locking groove 8 for restricting the movement of the positioning rod 20.

[0042] In the above embodiment, the first positioning post 16 passes through the first locking hole, the second positioning post 17 passes through the second locking hole, and the locking groove 8 includes an entry groove and a locking groove that are interconnected. The entry groove is connected to the first locking hole. When it is necessary to replace the support member 2 of different models, firstly, the positioning rod 20 is lifted, and the pin 19 rotates in the first and second locking holes. When the positioning rod 20 disengages from the locking groove, and the central axis of the positioning rod 20 is perpendicular to the central axis of the entry groove, the positioning rod 20 is pulled in a direction away from the second locking hole, so that the pin 19 disengages sequentially from the second positioning post 17 and the first positioning post 16, and then moves along the direction of the axis of the first positioning post 16. Move the support member 2 upwards, and the first positioning post 16 and the second positioning post 17 disengage from the first positioning hole 14 and the second positioning hole 15, completing the disassembly. When installation is required, insert the first positioning post 16 and the second positioning post 17 of the new-sized support member 2 into the first positioning hole 14 and the second positioning hole 15. Then, the pin 19 sequentially passes through the first locking hole and the second locking hole into the first positioning post 16 and the second positioning post 17. At this time, the central axis of the positioning rod 20 is perpendicular to the central axis of the groove. After the pin 19 is fully inserted into the second positioning post 17, rotate the positioning rod 20 so that the positioning rod 20 enters the locking groove, completing the installation. This design method can quickly complete the replacement of different models of support devices, thus further improving the replaceability of the support tooling and achieving the effect of easy installation, disassembly, replacement, and movement.

[0043] In a preferred embodiment, the adjustment mechanism 4 includes a first lifting assembly and a second lifting assembly spaced apart on the base 1, and the two lifting structures can independently adjust their lifting height. Furthermore, in this embodiment, the number of lifting plates 13, the number of first positioning holes 14, the number of second positioning holes 15, the number of first positioning posts 16, the number of second positioning posts 17, and the number of limiting members 18 are preferably two, i.e., as shown... Figure 2 As shown, the first lifting component corresponds to one group, and the second lifting component corresponds to one group.

[0044] In the above embodiments, the synchronous lifting of the first lifting component and the second lifting component simply changes the height of the support member 2; when the first lifting component and the second lifting component lift differently, one lifts and the other falls, or the final heights of the lifting and falling are different, the support member 2 swings; this design is flexible and easy to adjust the position of the boiler header, thereby assisting in the welding of the header.

[0045] In a preferred embodiment, the first lifting assembly and the second lifting mechanism have the same structure, both including a pair of support cylinders 9 disposed on the base 1, a lifting screw 10 passing through the support cylinder 9, and a rotating nut 11 that is in transmission cooperation with the lifting screw 10. The lifting end of the lifting screw is connected to the support member 2.

[0046] In the above embodiment, the rotating nut 11 rotates, causing the lifting screw to move up and down within the support cylinder 9, thus fulfilling the movement requirements of the lifting mechanism. The lifting screw 10 and the rotating nut 11 can be ball screws; it should be noted that when using ball screws, self-locking nuts are preferred. This design achieves lifting through rotation, making it suitable for containers that need to be lifted to different heights, thus satisfying the versatility of the support device.

[0047] In a preferred embodiment, the rotating nut 11 is provided with a pair of operating handles 12 on its ring side.

[0048] In the above embodiments, when the resistance arm (i.e., the radius of the rotating nut 11, from the center of the rotating nut 11 to its edge) and the resistance (i.e. the frictional force that needs to be overcome to rotate the rotating nut 11) are constant, the longer the power arm (i.e., the distance from the pushing point to the center of the rotating nut 11), the less power is required. The operating handle 12 adopts the above-mentioned lever principle, which allows the operator to rotate the rotating nut 11 with less effort and also meets the need for manual lifting and lowering operation, making the use of the support device more convenient.

[0049] In a preferred embodiment, the first lifting component and the second lifting mechanism described above have the same structure, both being hydraulic cylinders.

[0050] In the above embodiments, the hydraulic cylinder can withstand a large weight, provide a strong lifting force, and has good smoothness of operation, enabling precise lifting control. Therefore, the support device in this design can support a large weight of the header, and the adjustment of the header position will be more accurate.

[0051] In a preferred embodiment, the base 1 includes two double I-beam steel structure seats 5, and the first lifting component and the second lifting component are respectively disposed on the two double I-beam steel structure seats 5.

[0052] In the above embodiment, the double I-beam steel structure base 5 is made of multiple steel plates welded together, which enhances the load-bearing strength of the base 1 at the lowest possible cost, while also having the advantages of good stability and convenient processing.

[0053] In summary, the embodiments of this utility model provide a boiler header adjustment support device. This support device can be used to place the boiler header, preventing it from rolling during placement, facilitating transportation, and also has flexible adjustment capabilities, bringing convenience to subsequent welding.
