Description

Technical Field

[0001] This utility model belongs to the field of head processing and welding technology, and in particular relates to a welding equipment for spherical heads and pipe seats. Background Technology

[0002] When welding the spherical head nozzle seat 3, due to the special structure of the hemispherical head 1 (it is hemispherical), and the two nozzle seats 3 on one hemispherical head 1 are not coaxial, the included angle between the center lines of the two nozzle seats 3 on one hemispherical head 1 is 90 degrees, and they are symmetrically arranged on both sides of the hemispherical head 1. Therefore, it is impossible to use an automatic welding machine to completely weld the nozzle seat 3 onto the hemispherical head 1 on rotating rollers.

[0003] In production practice, for situations where a hemispherical head 1 has two connecting pipe seats 3 with different axes, existing technologies cannot achieve automatic welding of the hemispherical head 1 and the two connecting pipe seats 3 with different axes. Patent CN119973533A, a welding structure and method for a boiler separator head connecting pipe, is only applicable to solutions with one connecting pipe (i.e., one connecting pipe seat) and the connecting pipe is located at the center of the hemispherical head. It is not applicable to two connecting pipe seats 3 with a large skew angle. Utility Model Content

[0004] This utility model addresses the aforementioned problems by providing a welding device for a spherical head and a connecting pipe seat suitable for a hemispherical head 1 with two different shafts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: the present invention includes two bases 7, characterized in that each base 7 is symmetrically provided with roller brackets 6 on both sides, and rollers 61 are provided on the roller brackets 6; It also includes two connecting rods 3 that pass through the diagonal positions of the two interlocking hemispherical heads 1 and can be connected to the connecting rods 3; One end of the transverse support rod 4 is supported by two rollers 61 on one side of the base 7, and the other end of the transverse support rod 4 is supported by two rollers 61 on the other side of the base 7. The roller 61 rotates in conjunction with the end of the transverse support rod 4; One side roller 61 on one side base 7 is driven by the driving force output end of the roller drive device.

[0006] As a preferred embodiment, the transverse support rod 4 of this invention is provided with an end fitting 5 at its end. The end fitting 5 is concentric with the transverse support rod 4, and the outer diameter of the end fitting 5 is larger than the outer diameter of the transverse support rod 4.

[0007] As another preferred embodiment, the support rod 4 of this invention is welded to the end connector 5.

[0008] As another preferred embodiment, the two interlocking hemispherical end caps 1 of this invention are connected by spot welding.

[0009] As another preferred embodiment, the connecting pipe seat 3 of this utility model is spot welded to the transverse support rod 4.

[0010] As another preferred embodiment, after the transverse support rod 4 of this utility model passes through the two connecting pipe seats 3 at the diagonal positions on the two interlocking hemispherical end caps 1 and is connected to the connecting pipe seats 3, the lengths of the transverse support rod 4 on both sides of the two interlocking hemispherical end caps 1 that expose the connecting pipe seats 3 are equal.

[0011] As another preferred embodiment, the lower ends of both sides of the outer end of the base 7 of this utility model have outwardly extending first base plates 9. The upper ends of both sides of the first base plates 9 are connected to the outer end of the base 7 through right angle plates 10. The vertical edge of the right angle plate 10 is connected to the outer end face of the base 7, and the horizontal edge of the right angle plate 10 is connected to the upper end face of the first base plate 9. A horizontal strip hole 11 is provided on the first base plate 9.

[0012] As another preferred embodiment, the roller drive device of this invention is a speed reducer.

[0013] As another preferred embodiment, the support rod 4 between the connector seat 3 and the end connector 5 of this utility model is provided with a reinforcing rib 15, and the reinforcing rib 15 is welded to the support rod 4 and the connector seat 3 respectively.

[0014] Secondly, the roller bracket 6 of this utility model includes two side upright plates 12, and a roller 61 is disposed between the two side upright plates 12. The two ends of the shaft of the roller 61 are connected to the upper part of the two side upright plates 12 through bearings.

[0015] In addition, the upper part of the upright plate 12 of this utility model is trapezoidal and the lower part is rectangular; the lower end of the upright plate 12 has a second base plate 13 extending outward near the middle of the base 7, and the upper ends of both sides of the second base plate 13 are connected to the outer end of the upright plate 12 through the connecting upright plate 14; the upper part of the connecting upright plate 14 is a right trapezoid and the lower part is rectangular; the inner side of the connecting upright plate 14 is connected to the outer end face of the upright plate 12, and the lower end face of the connecting upright plate 14 is connected to the upper end face of the second base plate 13.

[0016] The beneficial effects of this utility model.

[0017] Before using the equipment described in this application, the connector 3 has been spot-welded to the inlet of the hemispherical head 1. The spot welding only serves to keep the connector 3 and the hemispherical head 1 in a state of being connected, not to achieve a final, reliable weld. The support rod 4 is passed through the two connectors 3 located diagonally on the two interlocking hemispherical heads 1, and then the two hemispherical heads 1 are joined together. Spot welding is then performed manually at the joint to form the head weld 2, thus temporarily fixing the two hemispherical heads 1 together. The transverse support rod 4 is then temporarily spot-welded to the connector 3 for further temporary fixation.

[0018] The purpose of this invention is to provide auxiliary equipment for the process of reliably welding the connecting pipe seat 3 and the hemispherical head 1 together using an automatic welding machine.

[0019] The purpose of this invention is to design a device that allows the connector seat 3 and the hemispherical head 1 to rotate together. That is, the connector seat weld 8 of the connector seat 3 and the hemispherical head 1 can rotate relative to the welding head of the automatic welding machine (the welding head remains stationary). This allows the automatic welding machine to reliably weld the connector seat weld 8 and ensure the connection strength between the connector seat 3 and the hemispherical head 1.

[0020] When this utility model is in use, the two ends of the transverse support rod 4 are placed on the upper ends of the gaps between the two rollers 61 on the two side bases 7. The two interlocking hemispherical heads 1 are lifted and can rotate. The pipe seat 3 rotates coaxially with the transverse support rod 4. The welding part of the pipe seat 3 and the hemispherical head 1 (i.e., the pipe seat weld 8) is exposed at a position perpendicular to the ground and has a certain spatial distance from the ground, which facilitates the welding head of the automatic welding machine to perform welding work on the pipe seat weld 8.

[0021] This utility model device can make the centers of the connecting pipe seats 3 on the diagonal lines of the two hemispherical heads 1 coaxial, and can perform automatic welding work. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The scope of protection of the present invention is not limited to the following description.

[0023] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0024] As shown in the figure, this utility model includes two bases 7, each base 7 is symmetrically provided with a roller bracket 6 on both sides, and a roller 61 is provided on the roller bracket 6; It also includes two connecting rods 3 that pass through the diagonal positions on the two interlocking hemispherical heads 1 and can be connected to the connecting rods 3; One end of the transverse support rod 4 is supported by two rollers 61 on one side of the base 7, and the other end of the transverse support rod 4 is supported by two rollers 61 on the other side of the base 7. The roller 61 rotates in conjunction with the end of the transverse support rod 4; One side roller 61 on one side base 7 is driven by the driving force output end of the roller drive device.

[0025] Only one roller 61 is the driving roller, while the other rollers 61 are driven rollers.

[0026] The roller drive device is a speed reducer. A speed reducer is easy to control. The speed reducer... Figure 1 The connection structure between the reducer and the driven roller is not shown in the figure; it is a conventional connection structure.

[0027] The roller bracket 6 can be welded to the base 7 for a secure connection.

[0028] The transverse support rod 4 is provided with an end fitting 5 at its end. The end fitting 5 is concentric with the transverse support rod 4, and the outer diameter of the end fitting 5 is larger than the outer diameter of the transverse support rod 4. Welding large-diameter end fittings 5 ​​to both ends of the transverse support rod 4 increases the height and torque, thus overcoming resistance and maintaining rotation.

[0029] The support rod 4 is welded to the end connector 5.

[0030] The two interlocking hemispherical heads 1 are connected by spot welding. The hemispherical heads 1 are very heavy; spot welding ensures a strong metal-to-metal connection, guaranteeing stability and safety during operation.

[0031] The connecting pipe seat 3 is spot welded to the transverse support rod 4.

[0032] After the transverse support rod 4 passes through the two connecting pipe seats 3 at the diagonal positions on the two interlocking hemispherical heads 1 and connects with the connecting pipe seats 3, the lengths of the transverse support rod 4 protruding from the connecting pipe seats 3 on both sides of the two interlocking hemispherical heads 1 are equal. That is, it ensures that the two interlocking hemispherical heads 1 are located in the middle position between the two bases 7 on both sides.

[0033] The lower ends of both sides of the outer end of the base 7 have outwardly extending first base plates 9. The upper ends of both sides of the first base plates 9 are connected to the outer end of the base 7 through right-angle plates 10. The vertical edge of the right-angle plate 10 is connected to the outer end face of the base 7, and the horizontal edge of the right-angle plate 10 is connected to the upper end face of the first base plate 9. The first base plate 9 is provided with horizontal strip holes 11. This structure increases the contact area between the base and the ground, enhancing stability.

[0034] The roller bracket 6 includes two side plates 12, and a roller 61 is disposed between the two side plates 12. The two ends of the roller 61 shaft are connected to the upper part of the two side plates 12 through bearings.

[0035] The upper part of the upright plate 12 is trapezoidal, and the lower part is rectangular. Near the middle of the base 7, the lower end of the upright plate 12 has an outwardly extending second base plate 13. The upper ends of both sides of the second base plate 13 are connected to the outer ends of the upright plate 12 via connecting upright plates 14. The upper part of the connecting upright plate 14 is a right-angled trapezoid, and the lower part is rectangular. The inner side of the connecting upright plate 14 is connected to the outer end face of the upright plate 12, and the lower end face of the connecting upright plate 14 is connected to the upper end face of the second base plate 13. This structure enhances the stability of the roller bracket 6, provides greater load-bearing capacity, and prevents tilting.

[0036] The second base plate 13 can be welded to the upright plate 12 and the base 7 respectively.

[0037] A reinforcing rib 15 is provided on the support rod 4 between the connector seat 3 and the end connector 5. The reinforcing rib 15 is welded to both the support rod 4 and the connector seat 3. The reinforcing rib 15 is used as reinforcement and welded to the connector seat 3 to improve stability.

[0038] The use and working process of this utility model are described below with reference to the accompanying drawings.

[0039] Upon arrival at the factory, the connector 3 had already been spot-welded to the connector opening of the hemispherical head 1. The two hemispherical heads 1 were then lifted using a crane (each hemispherical head 1 is equipped with lifting lugs). Figure 1 (Not shown in the drawing) The support rod 4 is passed through the two connecting pipe seats 3 at the diagonal positions on the two hemispherical heads 1 by a crane. The accurate position of each component is found by the through support rod 4. Then the two hemispherical heads 1 are joined together and manually spot welded at the joint to form the head weld 2, so that the two hemispherical heads 1 are combined together.

[0040] Position the two hemispherical heads 1 at the middle of the support rod 4, then weld the top of the connector seat 3 to the inner end of the transverse support rod 4. Weld the end connectors 5 to both ends of the support rod 4.

[0041] The entire equipment is lifted using a crane. The end connectors 5 on both sides are placed between the rollers 61 on both sides, and the welding head of the automatic welding machine is aligned with the weld seam 8 of the connector seat and inserted vertically into the seam, keeping the welding head stationary. The rollers 61 are driven to rotate, which in turn causes the two mating hemispherical heads 1 to start rotating. The weld seam 8 of the connector seat rotates relative to the welding head of the automatic welding machine (while the welding head remains stationary), and the weld seam 8 of the connector seat is welded using the automatic welding machine.

[0042] After the first pair of connector seats 3 are welded to the spherical head 1 (i.e., after the weld seam 8 of the connector seats is completed), the automatic welding machine is removed, allowing the support rod 4 to separate from the end connector 5, and the pipe seat hole 3 to separate from the transverse support rod 4 (this separation can be achieved using a cutting machine. The connector seat 3 and the transverse support rod 4 are spot-welded together with a pre-existing gap, so the cutting machine will not damage the base material). After the transverse support rod 4 is pulled out, it is then inserted into the second pair of connector seats 3, and the aforementioned process is repeated.

[0043] After both pairs of connectors 3 are welded to the spherical head 1, the two hemispherical heads 1 can be separated (this separation can be achieved using a cutting machine. The two hemispherical heads 1 are spot-welded together with a pre-existing gap, so the cutting machine will not damage the main body).

[0044] Due to the unique structure of the end cap, the weld seams of the two connecting pipe seats 3 are not parallel to the horizontal plane of the ground, exhibiting a certain angular deviation, and cannot be secured to welding equipment. Currently, there is no automatic welding equipment on the market that solves this problem. However, using this invention, two connecting pipe seats 3 can be welded at once, resulting in higher efficiency.

[0045] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
