[0045] Example 1

[0046] Reference Figure 1 - Fig.11:This embodiment provides a technical solution: a pipeline installation welding processing device, which is used to weld two sections of pipelines 1 to be welded at a construction site, and includes a pipeline fixing component 3 and a welding component 4, wherein the pipeline fixing component 3 includes a fixed base 300 and two second hoops 301, and the sides of both ends of the fixed base 300 are provided with second extension parts 3000, and the two ends of the fixed base 300 form a semicircular structure at the upper opening of the second extension part 3000, and the second hoops 301 adopt a circular ring structure. The two second hoops 301 are movably assembled at the two end positions of the fixed base 300, so that the second hoops 301 can be combined with the upper opening of the fixed base 300 to form a complete circular ring structure, and the welding Component 4 is installed in the middle of the pipeline fixing component 3, and the welding component 4 includes a lower support ring frame 400 and an upper support ring frame 401. The lower support ring frame 400 and the upper support ring frame 401 both adopt a semicircular ring structure, one end of the lower support ring frame 400 and the upper support ring frame 401 are movably connected, and the other end is detachably connected. The lower support ring frame 400 and the upper support ring frame 401 both adopt a semicircular ring structure, and the lower support ring frame 400 and the upper support ring frame 401 can be spliced ​​to form a complete circular ring. The inner side of the lower support ring frame 400 and the upper support ring frame 401 is equipped with a welding seat 406 that can rotate around the central inner wall of the lower support ring frame 400 and the upper support ring frame 401, and a welding head 404 is installed on the welding seat 406.

[0047] Working principle: The device is used at the construction site to weld two sections of pipes to be welded 1. When in use, first open the pipe fixing assembly 3 and the welding assembly 4, that is, flip the two second hoops 301 in the pipe fixing assembly 3 and the upper support ring frame 401 in the welding assembly 4 upward and open them, and then snap them under the connection position of the two sections of pipes to be welded 1, insert the ends of the two sections of pipes to be welded 1 above the fixed base 300, so that the connection position of the two sections of pipes to be welded 1 is located inside the lower support ring frame 400 and the upper support ring frame 401 (weld seam and welding head 401). 04 are on the same vertical plane, the weld is the joint seam of the two sections of the pipe 1 to be welded), then turn over the second hoop 301, and cover and fix the end of the pipe 1 to be welded by the second hoop 301 and the fixed base 300, turn over the upper support ring frame 401, so that the lower support ring frame 400 and the upper support ring frame 401 surround the end of the pipe 1 to be welded, open the welding head 404, and then the two sections of the pipe 1 to be welded can be welded. During the welding process, the welding seat 406 rotates around the central inner wall of the lower support ring frame 400 and the upper support ring frame 401 for one circle, and the welding process is completed.

[0048] It should be noted that: the device is equipped with a pipe fixing component 3, which can clamp and fix the ends of the two sections of the pipe 1 to be welded before and during the welding of the pipe, thereby ensuring the stability of the two sections of the pipe 1 to be welded during welding, thereby ensuring the welding effect, and the welding seat 406 in the device is installed on the inner side of the lower support ring frame 400 and the upper support ring frame 401, and the welding head 404 can be driven by the welding seat 406 to rotate around the central inner wall of the lower support ring frame 400 and the upper support ring frame 401 for welding. Therefore, during welding, the distance between the welding head 404 and the pipe 1 to be welded is always fixed, so that the welding effect at each position of the pipe is consistent and stable, and the connection strength of the pipe is improved.

[0049] This embodiment provides a pipeline installation welding processing device, such as Figure 8 - Fig.11 As shown, since the lower support ring frame 400 and the upper support ring frame 401 need to be able to be opened and closed for the installation of the entire device, how to achieve unimpeded rotation of the welding seat 406 on the inner side of the lower support ring frame 400 and the upper support ring frame 401 of the disconnected structure? In this embodiment, the inner sides of the lower support ring frame 400 and the upper support ring frame 401 are both circumferentially provided with a ring cavity 408, and a semicircular gear ring 409 is sleeved and installed in the ring cavity 408 on the lower support ring frame 400 and the upper support ring frame 401, and the welding seat 406 is fixedly connected to the middle part of one of the gear rings 409, and the two gear rings 409 can be on the upper support ring frame 401 and When the lower support ring frame 400 is flipped and snapped together, it is combined into a complete circular ring structure. A receiving portion 411 is installed on the top of the upper support ring frame 401. A gear 410 is installed in the receiving portion 411 through a rotating shaft. The gear 410 is meshed and connected with the gear ring 409. A servo motor 402 for driving the gear 410 to rotate is installed on the outer side of the receiving portion 411. When the servo motor 402 is running, the gear ring 409 makes a circular motion through the meshing action of the gear 410 and the gear ring 409, and the welding seat 406 is fixedly connected to the gear ring 409. Therefore, when the gear ring 409 rotates, the welding seat 406 rotates synchronously, thereby realizing rotary welding.

[0050] This embodiment provides a pipeline installation welding processing device, such as Fig.10 As shown, in order to ensure the overall consistency of the two semicircular toothed rings 409 after combination, in this embodiment, the two toothed rings 409 are located at one end where the lower support ring frame 400 and the upper support ring frame 401 are rotatably connected, and a magnetic plate 4091 and a magnetic groove 4090 are respectively provided, wherein the magnetic groove 4090 is opened on the inner side of the end surface of the toothed ring 409, when the lower support ring frame 400 and the upper support ring frame 401 are flipped and closed, the magnetic plate 4091 is stopped and engaged in the magnetic groove 4090, which can significantly improve the consistency of the two toothed rings 409 after combination, thereby driving the welding seat 406 to rotate smoothly and stably.

[0051] This embodiment provides a pipeline installation welding processing device. In order to prevent the gear ring 409 from "derailing", as shown in FIG. Figure 8 - Fig.11 As shown, in this embodiment, anti-slip rings 4092 are provided on both side edges of the gear ring 409, and anti-slip grooves 412 are circumferentially opened on the inner wall of the ring cavity 408. The anti-slip rings 4092 are engaged in the anti-slip grooves 412, so that the gear ring 409 can be restricted by the anti-slip rings 4092 and the anti-slip grooves 412 when rotating, thereby preventing the gear ring 409 from "derailing" and making the welding process smooth and stable.

[0052] It should be noted that: during the welding process, the gear ring 409 needs to be rotated, and after the welding is completed, the two sections of the gear ring 409 need to follow the flipping and separation of the upper support ring frame 401. In order to prevent the gear ring 409 from being blocked by the anti-slip ring 4092 and unable to open, the anti-slip ring 4092 at the end of the gear ring 409 inside the upper support ring frame 401 cannot completely separate from the anti-slip groove 412 on the inner wall of the lower support ring frame 400 when the gear ring 409 is separated. Fig.10 As shown, the anti-slip ring 4092 is retracted at the two end positions of the gear ring 409, and the retracted length is less than 1 / 4 of the length of the lower support ring frame 400, that is, the anti-slip ring 4092 is not provided at the two end positions of the gear ring 409, which will neither affect the anti-derailment effect of the gear ring 409 nor hinder the opening of the upper support ring frame 401 after welding is completed.

[0053] This embodiment provides a pipeline installation welding processing device, in order to reduce the pressure of the anti-slip ring 4092 when the gear ring 409 rotates, and improve the moving stability of the welding seat 406, such as Figure 8 - Fig.11 As shown, in this embodiment, a rail 405 is further provided on the inner wall of the annular cavity 408 along the circumferential direction, and an arc-shaped groove 4060 adapted to the rail 405 is provided on the side of the welding seat 406. The arc-shaped groove 4060 is engaged on the rail 405, and the welding seat 406 can slide along the rail 405.

[0054] This embodiment provides a pipeline installation welding processing device, in order to achieve the connection between the lower support ring frame 400 and the upper support ring frame 401, and ensure that the lower support ring frame 400 and the upper support ring frame 401 are tightly matched after connection, such as Figure 8 , Fig. 9As shown, in this embodiment, a connecting portion 4010 is provided at one end of the lower support ring frame 400, and an end groove 4000 is provided at one end of the upper support ring frame 401. The connecting portion 4010 is inserted into the end groove 4000 and is rotatably connected through the shaft 4001 to realize the movable connection between the lower support ring frame 400 and one end of the upper support ring frame 401. The outer sides of the other ends of the lower support ring frame 400 and the upper support ring frame 401 are both provided with convex portions 407, which are made of ferromagnetic material, and the surface of each convex portion 407 is provided with a socket. The ring frame 400 and the upper support ring frame 401 are provided with a lock 403 at one end of the protrusion 407, and a plurality of magnetic posts 4030 adapted to the sockets are provided on one side of the lock 403. The magnetic posts 4030 are inserted into the sockets on each protrusion 407 one by one, so that the lower support ring frame 400 and one end of the upper support ring frame 401 are locked. When the lock 403 is removed, the lower support ring frame 400 and the upper support ring frame 401 can be separated by flipping, thereby realizing a detachable connection between the lower support ring frame 400 and one end of the upper support ring frame 401.

[0055] It should be noted that: in order to ensure that the lock buckle 403 is easy to insert, the front end of the magnetic column 4030 adopts a conical structure. In order to ensure that the lower support ring frame 400 and the upper support ring frame 401 can be completely locked after the lock buckle 403 is inserted, the spacing of the vertical magnetic column 4030 is set to be consistent with the spacing of the two vertical sockets after the lower support ring frame 400 and the upper support ring frame 401 are combined.

[0056] Example 2

[0057] Reference Figure 1-4 In order to ensure that the ends of the two pipes 1 to be welded can be completely butted together before welding, thereby ensuring the strength of welding and ensuring the stability of the device in clamping the two pipes 1 to be welded, this embodiment provides a technical solution: both ends of the pipe fixing component 3 are provided with auxiliary butt-jointing components 2, the auxiliary butt-jointing components 2 include a movable base 200, a first hoop 201 and a driving mechanism, wherein the movable base 200 is arranged at one end of the pipe fixing component 3, and both end sides of the movable base 200 are provided with a first extension part 2000, and the movable base The two ends of 200 form a semicircular structure at the upper opening of the first extension part 2000. The first hoop 201 adopts a circular ring structure. The first hoop 201 is movably assembled at the two end positions of the movable base 200, so that the first hoop 201 can be combined with the upper opening of the movable base 200 to form a complete circular ring structure. The circular ring structure is concentric with the circular ring structure formed by the second hoop 301 and the upper opening of the fixed base 300, and has the same diameter. The driving mechanism is installed on the movable base 200, and is used to control the movable base 200 to move in the horizontal direction.

[0058] It should be noted that: when in use, the first hoop 201 is opened synchronously with the pipe fixing component 3 and the welding component 4. When the weld and the welding head 404 do not correspond when the two sections of the pipe 1 to be welded are assembled, the pipe fixing component 3 is not locked, and the first hoop 201 is locked with the movable base 200. At this time, the movable base 200 is controlled to move by the driving mechanism until the two sections of the pipe 1 to be welded are completely connected and the weld and the welding head 404 are kept corresponding, and then the pipe fixing component 3 is locked and the welding operation is performed.

[0059] Further, the driving mechanism includes an adjusting motor 205, an adjusting rod 203, a matching nut 202 and a limiting slide rail 204, wherein the adjusting motor 205 is fixedly mounted on the outer side of the movable base 200, one end of the adjusting rod 203 is rotatably inserted into the movable base 200 and is drivingly connected to the output shaft of the adjusting motor 205, and the other end has a threaded structure, the matching nut 202 and the adjusting rod 203 are on the same straight line and are embedded in the fixed base 300, the end of the adjusting rod 203 is screwed and sleeved in the matching nut 202, the limiting slide rail 204 is fixed on the outer side of the fixed base 300, and the movable base 200 is slidably sleeved on the limiting slide rail 204;
