Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped pipe welding equipment, in particular to a special-shaped pipe girth welding frame. Background Art

[0002] With the development of the times, a number of metal pipe structures different from the columnar structure of conventional models have emerged according to different usage scenarios and installation requirements. For example, spiral special-shaped pipes can be used to increase the length and save space in the field of heat exchange, thereby increasing the contact area between fluids and improving heat exchange efficiency. The spiral structure will cause turbulence in the fluid, which helps to break the boundary layer and promote heat transfer. Therefore, this type of spiral special-shaped pipe structure has broad market prospects in the field of heat exchange or liquid transmission.

[0003] This type of special-shaped pipe needs to be provided with an interface structure at least on one end. If this type of interface structure is integrally formed with the special-shaped pipe, not only will the processing cost be high, but the integral forming will also be difficult, which will affect the production efficiency. Therefore, the special-shaped pipe and the interface are generally circumferentially welded to facilitate the combination of the structures. Traditional circumferentially welded structures generally require the pipe body to be rotated to weld the interface. However, due to the uniqueness of this type of spiral special-shaped pipe structure, the common circumferentially welded frame on the market is used. On the one hand, it is difficult to ensure the normal rotation of the special-shaped pipe, and thus difficult to weld. On the other hand, due to the large size of this type of special-shaped pipe, positioning and rotation are more difficult. Therefore, it is necessary to design a device to support this type of special-shaped pipe structure to ensure the normal progress of circumferential welding. Utility Model Content

[0028] In the description of the present invention, unless otherwise specified, “a plurality of” means two or more.

[0029] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0030] The following combination Figures 1 to 5 , describing a special-shaped pipe ring welding frame provided by an embodiment of the utility model, including a base 10 and a product support frame 20. A clamping seat 11 and a driving assembly 12 are respectively provided on both sides of the base 10. The driving assembly 12 is rotatably connected to the product support frame 20. The product support frame 20 includes a connecting portion 21 and a supporting portion 22. The connecting portion 21 is connected to the driving assembly 12, and the supporting portion 22 is perpendicular to the connecting portion 21. One end thereof is a special-shaped pipe supporting position 23, and the other end is provided with a weight supporting position 24, and the weight has the same weight as the special-shaped pipe.

[0031] Among them, for the structure of special-shaped tube, such as Figure 1 As shown, the special-shaped tube is a spiral disc tube, wherein the higher end is connected with a T-shaped interface, and the other end is arranged at the bottom and can also be connected with a T-shaped interface to weld the T-shaped interface and the special-shaped tube body.

[0032] from Figure 1 As can be seen, the base 10 has a conventional frame structure, with an L-shaped connection portion 21. The connection portion 21 connects to the drive assembly 12 at a position higher than the portion of the connection portion 21 that supports the support portion 22. The support portion 22 has a Z-shaped structure, with the weight support portion 24 being higher than the height of the special-shaped tube support portion 23. The weight support portion 24 is provided with multiple mounting holes along its length.

[0033] It should be noted that, as needed, the weight support position 24 can be provided with multiple weights to ensure that the weight of the weight is the same as the special-shaped tube. In addition, in order to further ensure the accuracy of the weight adjustment between the two, multiple mounting holes can make the weight close to or away from the special-shaped tube, further ensuring the balance on both sides.

[0034] Furthermore, since the position where the connecting portion 21 is connected to the driving component 12 is higher than the part of the connecting portion 21 that carries the support portion 22, the height of one side of the connecting driving component 12 is higher and the other side can be lower. A supporting plate 13 is provided on one side of the clamping seat 11, and the clamping seat 11 is provided on the surface of the supporting plate 13. A vertical plate is vertically provided at one end of the supporting plate 13, and a cylinder is provided on one side of the vertical plate and the clamping seat 11.

[0035] Furthermore, if Figure 2 and Figure 3 As shown, the clamping seat 11 includes a symmetrically arranged clamping body 111, which has a bottom plate and two vertical plates, and the three are connected to form a U-shaped structure. The clamping body 111 on one side is connected to the cylinder 113 to clamp the welding position of the special-shaped pipe.

[0036] Specifically, a splint 114 is provided on both sides of the vertical plate, and an arc-shaped groove 115 is provided on the opposite side walls of the vertical plates of the two clamping bodies 111. The arc-shaped groove 115 surrounds the welding position of the special-shaped tube. The two splints 114 of a single vertical plate form a group, and a plurality of pulleys 112 are provided between each group of splints 114. In order to facilitate the setting of the pulley 112, the vertical plate can be set to slightly protrude from the vertical plate to provide sufficient placement space for the pulley 112, and pulleys 112 are provided on both sides of the arc-shaped groove 115 in the height direction, and the pulley 112 surrounds the tube body of the special-shaped tube.

[0037] It should be noted that the center of the clamping area between the clamping bodies 111 and the center of the rotational connection between the drive assembly 12 and the product support bracket 20 are collinear, that is, in the specific use process, the special-shaped tube structure is first positioned, and the weight of the special-shaped tube and the weight are matched, at this time the drive assembly 12 starts to move, driving the connecting part 21 to rotate, and the connecting part 21 drives the support part 22 to rotate, so that the special-shaped tube begins to flip over following the support part 22; since the center of the clamping area between the clamping bodies 111 and the center of the rotational connection between the drive assembly 12 and the product support bracket 20 are collinear, and due to the cooperation of the pulley 112, during the rotation process, the welding area of ​​the special-shaped tube clamped by the clamping seat 11 also rotates synchronously, thereby facilitating the girth welding machine to perform girth welding on the position to be welded; of course, for Figure 2 For special-shaped pipes that need girth welding at both ends, you can remove the other end of the girth welding after completing the girth welding of one end. The operation steps are the same as the previous girth welding method.

[0038] Among them, for the ring welding machine, it can adopt the common ring welding equipment on the market. It is necessary to ensure that the welding head is located in the welding area of ​​the clamping seat 11, and it is necessary to avoid the path of the support part 22 and the flipping of the special-shaped pipe to ensure the normal rotation and ring welding; since the welding head itself can be additionally set and the existing technology is relatively mature, the utility model does not make a specific description and limitation on the structure of the welding head here.

[0039] Furthermore, a cross positioning frame 25 is provided on the top of the special-shaped tube support position 23, and a block 26 is hingedly provided on the top of the cross positioning frame 25. A plurality of locking openings are provided on the surface of the special-shaped tube support position 23, and the cross positioning frame 25 is also provided with a plurality of locking openings, and the corresponding locking openings are detachably connected with a locking column 27.

[0040] Among them, such as Figure 5 As shown, the cross positioning frame 25 has a cross-shaped bottom and a vertical plate protruding upward. A stopper 26 can be provided on the top of the vertical plate. The special-shaped tube is arranged around the outside of the support plate to position the special-shaped tube; similarly, the setting of the locking port can be coordinated with the position adjustment of the weight support position 24 to ensure the weight balance on both sides; and the hinged stopper 26 structure can further play a role in positioning the special-shaped tube, thereby largely avoiding the problem of the special-shaped tube falling off during the rotation and flipping process.

[0041] It should be noted that in order to improve the positioning effect and positioning flexibility, the four cross sides of the cross positioning frame 25 can be set as a telescopic structure to adapt to special-shaped tubes of different sizes. Similarly, the telescopic structure and the hinged block 26 structure should also be provided with a locking column 27 to lock the position after positioning is completed to reduce the occurrence of falling off.

[0042] Preferably, if Figure 4 As shown, the base 10 has a support plate at the bottom, and the driving assembly 12 includes a motor 121, a driving wheel 122 and a driven wheel 123. The motor 121 is arranged on the surface of the support plate, and the output shaft of the motor 121 extends into one side of the base 10 and is connected to the driving wheel 122. The driving wheel 122 is connected to the driven wheel 123 to drive the product support bracket 20 to flip.

[0043] It can be understood that a belt drive can be used between the driving wheel 122 and the driven wheel 123 to ensure smooth transmission while providing overload protection for the equipment and ensuring safe and reliable use; furthermore, the height of the support plate and the position of the motor 121 should be such that the rotation and flipping of the connecting part 21 and the supporting part 22 should be ensured as much as possible to avoid obstruction of the rotation of the special-shaped tube.

[0044] In addition, if Figure 1 and Figure 4 As shown, the support plate of the base 10 on the side opposite to the driving assembly 12 can be provided with a control box, which can be connected to the motor 121 to control the direction, speed and start and stop of the motor 121, which is convenient to operate.

[0045] Other structures and operations of the special-shaped pipe ring welding frame according to the embodiment of the present invention are known to ordinary technicians in this field and will not be described in detail here.
