Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline welding processing, and in particular relates to a pipeline support welding processing device. Background Art

[0002] An offshore platform is an operating platform built at sea. Offshore operations are achieved by constructing a construction platform at sea. The most common offshore platform is a working platform for offshore oil extraction.

[0003] During the construction of offshore platforms, a large number of pipelines are needed. As important infrastructure on offshore platforms, the installation volume of pipelines is very large.

[0004] Therefore, during the construction of offshore platforms, it is necessary to weld and process a variety of matching construction pipelines according to actual needs, such as welding pipe seats and other connection structures on pipelines, welding transfer connection structures, etc.

[0005] During the welding process, the pipe is often welded in a suspended position, but during the welding process, welding operations are often required at different positions and angles on the pipe. Therefore, during the welding process, in order to facilitate welding, the pipe needs to be turned over and the welding position needs to be adjusted to facilitate welding.

[0006] However, in the actual welding process, especially when welding large-diameter and heavy pipes, it is not only difficult to flip the pipe, but also because the pipe has a large diameter and is heavy, the pipe needs to be positioned again after flipping, and after flipping again, the pipe needs to be loosened again. Such repeated operations are not only difficult to operate, but also cumbersome to operate.

[0007] However, the operation is difficult and the work is cumbersome, resulting in the inability to guarantee the safety of the operation during the flipping and adjusting posture during large-diameter pipeline welding operations. For example, after flipping to the specified angle, the brakes cannot be maintained, which can easily cause safety accidents. Utility Model Content

[0008] Based on the above background, the purpose of the utility model is to provide a pipeline support welding processing device.

[0009] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0010] A pipeline support welding processing device comprises a welding fixture mechanism, wherein the welding fixture mechanism comprises slide rails arranged at intervals on both sides, and support components for supporting and locking the pipeline are respectively arranged on the slide rails in a rolling manner;

[0011] The support assembly includes an outward turning tool rolling on a slide rail, and a clamp component for locking the pipe is fixedly connected to the outward turning tool;

[0012] Both ends of the pipeline are supported and positioned on support assemblies on the slide rails on both sides;

[0013] Both sides of the slide rail are respectively connected with a pushing assembly for pushing the outer flip tool to roll, the pushing assembly includes a pushing wheel abutting against the lower end of the side wall of the outer flip tool, the pushing wheel is connected with a pushing wheel frame, and the pushing wheel frame is connected with a hydraulic cylinder;

[0014] During the process of flipping the pipeline, open the hydraulic cylinder on one side, and the hydraulic cylinder pushes the push wheel to push the external flipping tooling to flip to the exposed welding position. Then the hydraulic cylinder on the other side pushes the push wheel to contact the other side of the external flipping tooling. The push wheels on both sides are in contact to keep the external flipping tooling pressed and locked.

[0015] Preferably, a rail groove is provided on the slide rail, the outward turning tool rolls in the rail groove, and the push wheel rolls in the rail groove.

[0016] Preferably, the clamp component includes an upper clamp and a lower clamp assembled and connected to the upper clamp.

[0017] Preferably, the top of the upper clamp is fixedly connected to the external turning tool through an adjustable connecting piece;

[0018] The bottom of the lower clamp is fixedly connected to the outer turning tool through an adjusting connector.

[0019] Preferably, the adjusting connecting member comprises a fixing seat fixedly connected to the clamp component, an adjusting rod is slidably connected to the fixing seat, and the adjusting rod is welded to the external turning tool;

[0020] The fixing seat is threadedly connected with a plurality of locking screws of the positioning and adjusting rods.

[0021] Preferably, the longitudinal cross-section of the outside-turning tool is annular.

[0022] Preferably, the spacing between the external turning toolings is adjusted by a spacing adjustment structure;

[0023] The spacing adjustment structure includes a long adjustment rod slidably mounted between the left side and the right side of the external flip tooling;

[0024] The spacing adjustment structure also includes an ear fixing plate welded on the side wall of the outward turning tooling, and the long adjustment rod is slidably assembled on the ear fixing plate.

[0025] Preferably, the front and rear ends of the long adjustment rod are respectively threadedly connected with a pair of nuts positioned on both sides of the ear fixing plate.

[0026] Preferably, the hydraulic cylinders are supported on the slide rails respectively through fulcrum structures;

[0027] The fulcrum structure includes a plurality of toothed convex plates welded to both sides of the top of the slide rail;

[0028] The fulcrum structure also includes a fixed plate fixedly connected to the hydraulic cylinder, and a support rod is slidably connected to the fixed plate. During the operation of the hydraulic rod, the support rod is limited between the toothed convex plates and uses the toothed convex plates as a fulcrum.

[0029] The utility model has the following beneficial effects:

[0030] 1. During the process of turning over the pipeline, if it turns to the right, at this time, pre-adjust the distance of the hydraulic cylinder on the right side (at this time, the push wheel on the right hydraulic cylinder is out of contact with the external turning tooling).

[0031] At this time, the support rod on the left hydraulic cylinder is passed through along the spacing between the toothed convex plates, and then passed through the through hole on the fixed plate until the two ends of the support rod are limited between the toothed convex plates. With the toothed convex plates as the fulcrum, the left hydraulic cylinder is opened at this time, and the hydraulic cylinder pushes the push wheel to roll on the slide rail. Under the push, the external flip tooling rolls on the slide rail, and the heavy pipe is flipped to adjust the angle. After flipping to the exposed welding position, it is convenient for welding. After flipping and rolling, the hydraulic cylinder on the right is supported between the toothed convex plates by the support rod in the same way, and the hydraulic cylinder is opened to push the push wheel to contact the other side of the external flip tooling. Under the resistance of the push wheels on both sides, the external flip tooling is kept in position, thereby preventing the external flip tooling from flipping during the welding process.

[0032] The above method not only realizes the process of welding, pushing the bulky pipe to flip and adjust the angle, so as to expose the hidden welding position, but also greatly increases the stability and safety of welding when the push wheels on both sides are in a deadlocked state during welding.

[0033] 2. The spacing of the external turning tooling is adjustable. During the working process, after measuring the length of the pipeline in advance and moving the distance between the slide rails in advance, the long adjustment rod is used to connect the external turning tooling on the slide rails on both sides, and then fastened with nuts. The external turning tooling on both sides forms an integrated turning structure to achieve synchronous turning.

[0034] Therefore, the advantages of this structure are: the spacing adjustment satisfies the adjustment of the support position according to the length of the pipeline, ensuring that the pipeline can maintain the best balance after being supported, thereby greatly improving the safety and stability during the operation.

[0045] Example 1

[0046] like Figure 1-5 As shown, a pipeline support welding processing device includes a welding fixture mechanism, which includes slide rails 4 spaced apart at the front and rear sides (the bottom of the slide rails 4 is fixedly connected to a track base 41), and support components for supporting and locking the positioning pipeline are respectively rollingly arranged on the slide rails 4.

[0047] Specifically, the support assembly includes an external turning tool 2 rolling on the slide rail 4 (the longitudinal cross-section of the external turning tool 2 is annular, made of thickened steel plate, and has a certain width, and the support surface between the track is large, so when turning over, the stability is relatively high and it is not easy to turn over). The external turning tool 2 is fixedly connected with a clamp component for locking the pipe. The two ends of the pipe are locked by the clamp component.

[0048] At the same time, both sides of the slide rail 4 are respectively equipped with a pushing component for pushing the external flipping tooling 2 to roll, and the pushing component includes a pushing wheel 51 that abuts against the lower end position of the side wall of the external flipping tooling 2, and the pushing wheel 51 is equipped with a pushing wheel frame 52, and the pushing wheel frame 52 is equipped with a hydraulic cylinder 53 (the hydraulic cylinder 53 is a multi-stage telescopic hydraulic cylinder disclosed in the prior art).

[0049] Specifically, a rail groove is formed on the slide rail 4, the outward turning tool 2 rolls in the rail groove, and the push wheel 51 rolls in the rail groove.

[0050] At the same time, the hydraulic cylinder 53 is supported on the slide rail 4 through a fulcrum structure; the fulcrum structure includes a plurality of toothed convex plates 42 welded to both sides of the top of the slide rail 4; the fulcrum structure also includes a fixed plate 531 fixedly connected to the hydraulic cylinder 53, and a support rod 54 is slidably connected to the fixed plate 531. During the operation of the hydraulic rod, the support rod 54 is limited between the toothed convex plates 42, and the toothed convex plates 42 are used as fulcrums.

[0051] During the process of turning over the pipeline, if it is turned over to the right side, at this time, the distance between the hydraulic cylinder 53 on the right side is pre-adjusted (at this time, the push wheel 51 on the hydraulic cylinder 53 on the right side is out of contact with the outer turning tool 2).

[0052] At this time, the support rod 54 on the left hydraulic cylinder 53 is passed through along the spacing between the tooth convex plates 42, and passed through the through hole on the fixed plate 531, until the two ends of the support rod 54 are limited between the tooth convex plates 42. With the tooth convex plate 42 as the fulcrum, the left hydraulic cylinder 53 is opened at this time, and the hydraulic cylinder 53 pushes the push wheel 51 to roll on the slide rail 4, and under the push, the external flip tool 2 rolls on the slide rail 4, and carries the bulky pipe to flip and adjust the angle, and flips to expose the welding position, which is convenient for welding. After flipping and rolling, the hydraulic cylinder 53 on the right side is supported between the tooth convex plates 42 by the support rod 54 in the same way, and the hydraulic cylinder 53 is opened to push the push wheel 51 to contact the other side of the external flip tool 2. Under the resistance of the push wheels 51 on both sides, the external flip tool 2 is kept in position, thereby preventing the external flip tool 2 from flipping during the welding process.

[0053] The above method not only realizes pushing the heavy pipe to flip and adjust the angle during welding to expose the hidden welding position, but also greatly increases the stability and safety of welding when the push wheels 51 on both sides are in a deadlocked state during welding.

[0054] At the same time, in the actual working process, the pushing components on both sides of the external flipping tool 2 cooperate with each other to realize the flipping of the external flipping tool to different directions, thereby realizing the flipping of the positioned pipe to different directions, and thus this method greatly improves the flexibility and efficiency of the welding process.

[0055] Example 2

[0056] like Figure 1-5 As shown, based on the structure of Example 1, the clamp component of this embodiment includes an upper clamp and a lower clamp 12 assembled and connected to the upper clamp 11. The top of the upper clamp 11 is fixedly connected to the external turning tool 2 through an adjustable connecting piece; the bottom of the lower clamp 12 is fixedly connected to the external turning tool 2 through an adjustable connecting piece.

[0057] Specifically, the adjusting connecting member includes a fixing seat 62 fixedly connected to the clamp component, and an adjusting rod 61 is slidably connected to the fixing seat 62 (a cylindrical groove is provided on the fixing seat 62 of the cylindrical structure, and the adjusting rod 61 slides in the cylindrical groove), and the adjusting rod 61 is welded to the external flipping tooling 2; a plurality of locking screws 621 for positioning the adjusting rod 61 are threadedly connected to the fixing seat 62.

[0058] During the process of locking the pipeline, the position of the lower clamp 12 at the lower end is pre-adjusted, and then the pipeline is supported on the lower clamp 12, and the locking screw 621 on the upper end position adjustment connector is loosened, and the upper clamp 11 is adjusted downward until the upper clamp 11 is clamped on the pipeline, and the upper clamp 11 and the connecting screws at both ends of the upper clamp 11 are tightened with nuts to lock and position the pipeline. After adjustment, the locking screw 621 is locked and squeezed onto the adjustment rod 61.

[0059] The advantages of the above method are that the upper clamp 11 and the lower clamp 12 can be adjusted in height, so in the actual working process, when encountering a large-caliber pipe, the distance between the upper clamp 11 and the lower clamp 12 can be increased, and the pipe can be positioned after being clamped. Although the pipe is not completely locked, the pipe can still be positioned. The connecting screw has a certain length, and after the upper clamp 11 and the lower clamp 12 hold the upper and lower sides of the pipe, the upper clamp 11 and the lower clamp 12 can still be partially locked by the connecting screw-nut structure, which is convenient for processing pipes of different diameters.

[0060] Example 3

[0061] like Figure 1-5 As shown, based on the structure of Example 1, in the actual working process, the spacing between the outward turning tooling 2 on both sides is adjusted according to the length of the pipeline, and the method is as follows: the spacing between the outward turning tooling 2 is adjusted by a spacing adjustment structure; the spacing adjustment structure includes a long adjustment rod 3 that is respectively slidably assembled between the left side and the right side of the outward turning tooling 2.

[0062] Specifically, the spacing adjustment structure also includes an ear fixing plate 13 welded on the side wall of the external turning tool 2, and the long adjustment rod 3 is slidably assembled on the ear fixing plate 13. The front and rear ends of the long adjustment rod 3 are also threadedly connected with a pair of nuts positioned on both sides of the ear fixing plate 13.

[0063] During the working process, after measuring the pipeline length in advance and moving the distance between the slide rails 4 in advance, the long adjustment rod 3 is used to connect the outward turning tooling 2 on the slide rails 4 on both sides, and then fastened with nuts. The outward turning tooling 2 on both sides forms an integrated turning structure to achieve synchronous turning.

[0064] Therefore, the advantages of this structure are: the spacing adjustment satisfies the adjustment of the support position according to the length of the pipeline, ensuring that the pipeline can maintain the best balance after being supported, thereby greatly improving the safety and stability during the operation.

[0065] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
