Description

Technical Field

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

[0002] During the design and construction of process pipelines such as offshore engineering upper modules and LNG onshore modules, process pipeline welding is common. If the welding at these locations is not properly controlled, it will often cause pipeline deformation, requiring a lot of manpower and material resources to correct the deformation after welding. Severe deformation may even cause the entire pipe section to be scrapped.

[0003] Specifically, during the pipeline welding process, it is often necessary to weld various auxiliary accessories on the pipeline, such as mounting seats, pipe seats and other additional structures. Therefore, during the welding process, the pipeline needs to be kept suspended, so as to expose the welding part and facilitate welding.

[0004] However, in the actual welding process, especially when welding a relatively long pipe, the pipe needs to be effectively supported after being suspended in the air. Only in this state can the pipe not be easily deformed after being suspended in the air. Otherwise, during welding, especially in common welding operations, the heavy pipe cannot be effectively supported, resulting in the pipe being easily bent and deformed, or even torn and damaged, which greatly reduces the service life of the pipe.

[0005] In addition, during the welding process, the pipeline needs to be positioned to prevent the pipeline from loosening during welding and causing safety accidents.

[0006] The support tooling currently used is mostly in the form of pads, but the disadvantages are also very obvious. After the pads are supported, it is difficult to move. During the welding process, once the support position needs to be adjusted, it is difficult to adjust. Moreover, when the pads are used, after the pipe is supported on the pads, the pads cannot be moved. Therefore, once the pipe support points are uneven (uneven pipe support points, such as a long pipe part that cannot be supported, resulting in excessive hanging and easy deformation), it is very difficult to adjust under the pressure of the heavy pipe.

[0007] At the same time, during the working process, especially when welding pipes with a slightly larger radius, it is difficult to keep the pipe from flipping after being supported on the pad. Once the pipe flips, the stability of the pipe is bound to be reduced. In severe cases, it will roll down from the pad position, and the safety of the welding operation cannot be guaranteed. Utility Model Content

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

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

[0010] A pipeline welding tool comprises rails arranged at intervals on both sides;

[0011] The track is equipped with a plurality of adjustment support units for supporting the pipeline during the welding process;

[0012] The adjustable support unit comprises locking assemblies spaced apart on both sides, and a plurality of hydraulic push components for adjusting the spacing are assembled and connected between the locking assemblies;

[0013] The locking assembly includes an upper locking hoop plate and a lower locking hoop plate assembled and connected to the upper locking hoop plate. During welding, the pipeline is positioned between the upper locking hoop plate and the lower locking hoop plate.

[0014] The lower locking hoop plate is connected with a slide, and the bottom of the slide is connected with a track wheel rolling on the track;

[0015] The upper locking hoop plate and the lower locking hoop plate are respectively equipped with a plurality of contact and pressure rolling members, and the contact and pressure rolling members roll against and on the pipe, so that the locking assembly can roll relative to the pipe.

[0016] Preferably, both left and right ends of the upper locking hoop plate and the lower locking hoop plate are integrally formed with horizontally protruding assembly parts, and a plurality of connecting screws are assembled and connected between the assembly parts.

[0017] Preferably, the upper ends of the slides are detachably connected to the side walls of the assembly portion of the lower locking hoop plate via connecting screws.

[0018] Preferably, the contact pressure rolling element comprises a threaded connecting rod portion, the inner end of the threaded connecting rod portion is fixedly connected to a cylindrical boss, and the end of the cylindrical boss is hinged with a steel rolling ball;

[0019] The threaded connecting rod is threadedly connected to the corresponding upper locking hoop plate and lower locking hoop plate.

[0020] Preferably, hydraulic pushing components are respectively assembled and connected between the left and right sides of the slide.

[0021] Preferably, the hydraulic pushing component includes a hydraulic cylinder, and a pushing rod is fixedly connected to the cylinder barrel and the plunger rod of the hydraulic cylinder respectively; a pair of connecting ear plates are welded and connected on both sides of the side wall of the slide, and a connecting screw is threadedly connected between the connecting ear plates; the pushing rod is fixedly connected to a mounting sleeve, and the mounting sleeve is threadedly connected to the connecting screw.

[0022] Preferably, the rail wheel comprises a wheel frame welded to the bottom of the carriage, and the wheel frame is rotatably connected to the rail wheel;

[0023] A rail groove is provided on the track, and the rail wheel rolls in the rail groove.

[0024] Preferably, long track slides are slidably connected to both sides of the slide respectively, and the long track slides are welded to the side walls of the track.

[0025] Preferably, the long track slide comprises a horizontal sliding portion slidably connected to the slide, and connecting portions are integrally formed at both ends of the horizontal sliding portion, and the connecting portions are welded to the side walls of the track.

[0026] The utility model has the following beneficial effects:

[0027] 1. During the working process, the adjusting support unit with rolling setting is used to facilitate the adjustment of the supporting position of the adjusting support unit to ensure that the pipeline can be fully and effectively supported and locked.

[0028] 2. During the working process, before clamping the pipe, the depth of the threaded connecting rod extending into the arc-shaped opening of the upper locking hoop and the lower locking hoop is pre-adjusted according to the thickness of the pipe. After the upper locking hoop and the lower locking hoop clamp the pipe, the steel rolling ball contacts the pipe. Since the contact and pressure rolling parts are distributed in an annular manner, they contact the pipe from multiple positions at the same time.

[0029] This method can effectively resist the pipeline, and secondly, the steel rolling ball can facilitate sliding and adjusting the locking position, facilitate welding operation and position adjustment, and facilitate exposing the welding position.

[0030] 3. During the working process, open the hydraulic cylinder. Since the two ends of the hydraulic cylinder use the slides on both sides as fulcrums, the locking components on the front and rear sides are pushed open during the extension of the hydraulic cylinder. Since the steel rolling balls on the locking components are in contact with the pipe, the steel rolling balls roll relative to the pipe during the pushing process, thereby reducing the resistance during the pushing process, protecting the pipe and facilitating the pushing. After pushing open, it is convenient for operators to perform operations such as welding and adjusting the support points. This method can achieve adjustment in a labor-saving manner.

[0041] Example 1

[0042] like Figure 1-5 As shown, a pipeline welding tool comprises a track 1 arranged at intervals on both sides (the bottom of the track 1 is supported by a plurality of pads); a plurality of adjustable support units for supporting the pipeline during welding are assembled and connected on the track 1. A section of the pipeline is supported by each adjustable support unit. Since the adjustable support units roll on the track 1, the spacing can be adjusted to ensure that the positions of the supported pipelines are uniform, thereby effectively protecting the pipelines.

[0043] The above-mentioned adjustable support unit includes locking components spaced apart at the front and rear sides, and two hydraulic pushing components for adjusting the spacing are assembled and connected between the locking components.

[0044] Specifically, the locking assemblies include an upper locking hoop plate and a lower locking hoop plate 32 assembled and connected to the upper locking hoop plate 31. During the welding process, the pipeline is positioned between the upper locking hoop plate 31 and the lower locking hoop plate 32 (specifically, it is clamped on the arc-shaped opening of the locking hoop plate).

[0045] The left and right ends of the upper locking hoop plate 31 and the lower locking hoop plate 32 are integrally formed with horizontally protruding assembly parts, and a number of connecting screws are assembled and connected between the assembly parts. After clamping the pipe in this way, it is convenient to connect and lock the upper locking hoop plate 31 and the lower locking hoop plate 32.

[0046] The lower locking hoop plate 32 is assembled and connected with a slide 34 (specifically, the upper end of the slide 34 is detachably assembled and connected to the side wall of the assembly portion of the lower locking hoop plate 32 through a connecting screw 342, which is convenient for disassembly), and the bottom of the slide 34 is assembled and connected with two track wheels 35 rolling on the track 1. Specifically, the track wheel 35 includes a wheel frame welded to the bottom of the slide 34, and the wheel frame is rotatably connected with a rail wheel; a rail groove is opened on the track 1, and the rail wheel rolls in the rail groove.

[0047] During operation, the above structure is used to facilitate adjustment of the support position of the adjustable support unit, ensuring that the pipeline can be fully and effectively supported and locked.

[0048] Example 2

[0049] like Figure 1-5 As shown, based on the structure of Example 1, the upper locking hoop plate 31 and the lower locking hoop plate 32 are respectively equipped with a plurality of contact pressure rolling members 33, and the contact pressure rolling members 33 roll against the pipe to achieve the rolling of the locking assembly relative to the pipe.

[0050] Specifically, the contact pressure roller 33 is used to facilitate the clamping and positioning of pipes of different thicknesses. After the pipe is clamped and positioned, the upper locking hoop plate 31 and the lower locking hoop plate 32 can adjust the clamping position relative to the clamped pipe on the horizontal line. The purpose is: during welding, the clamping position point can be adjusted according to the length and center of gravity of the pipe to ensure uniform support and protect the pipe. Secondly, during welding, the welding position can be avoided according to the welding position. If welding is required at the clamping position, the upper locking hoop plate 31 and the lower locking hoop plate 32 can be moved relative to the pipe to facilitate welding.

[0051] Specifically, the contact pressure rolling element 33 includes a threaded connecting rod 331, the inner end of which is fixedly connected to a cylindrical boss 332, and the end of the cylindrical boss 332 is hinged with a steel rolling ball 333 (the manner in which the steel rolling ball 333 is hinged to the cylindrical boss 332 is a conventional manner disclosed in the prior art, specifically, the steel rolling ball 333 is hinged in a hinge groove on the cylindrical boss 332); the threaded connecting rod 331 is threadedly connected to the corresponding upper locking hoop plate 31 and the lower locking hoop plate 32.

[0052] During operation, before clamping the pipe, the depth of the threaded connecting rod 331 inserted into the arc-shaped opening of the upper locking hoop 31 and the lower locking hoop 32 is pre-adjusted according to the thickness of the pipe. After the upper locking hoop 31 and the lower locking hoop 32 clamp the pipe, the steel rolling ball 333 contacts the pipe. Since the contact and pressure rolling element 33 is distributed in an annular manner, it contacts the pipe from multiple positions and angles at the same time.

[0053] This method can effectively resist the pipeline, and secondly, the steel rolling ball 333 can be easily slid to adjust the locking position due to the resistance, so as to facilitate the welding operation and the adjustment of the position, and to expose the welding position.

[0054] Example 3

[0055] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, hydraulic pushing components are respectively installed and connected between the left and right sides of the above-mentioned slide 34. The hydraulic pushing components facilitate pushing the locking components on both sides, thereby facilitating the adjustment of the locking support position (ensuring uniform support position) and exposing the welding position.

[0056] Specifically, the hydraulic pushing component includes a hydraulic cylinder 4, and a pushing rod 41 is fixedly connected to the cylinder barrel and the plunger rod of the hydraulic cylinder 4 respectively; a pair of connecting ear plates 341 are welded and connected on both sides of the side wall of the slide 34, and a connecting screw is threadedly connected between the connecting ear plates. The pushing rod 41 is fixedly connected to a mounting sleeve, and the mounting sleeve is threadedly connected to the connecting screw.

[0057] During operation, the hydraulic cylinder 4 is opened. Since the two ends of the hydraulic cylinder 4 use the slides 34 on both sides as fulcrums, the locking components on the front and rear sides are pushed open during the extension of the hydraulic cylinder 4. Since the steel rolling balls 333 on the locking components are in contact with the pipeline, the steel rolling balls 333 roll relative to the pipeline during the pushing process, thereby reducing the resistance during the pushing process, protecting the pipeline and facilitating the pushing. After pushing open, it is convenient for operators to perform operations such as welding and adjusting the support position.

[0058] Example 4

[0059] like Figure 1-5As shown, based on the structure of Example 1, the two sides of the slide 34 are respectively slidably connected with the long track slide 2, and the long track slide 2 is welded to the side wall of the track 1. The long track slide 2 includes a horizontal sliding part slidably connected to the slide 34, and the two ends of the horizontal sliding part are integrally formed with a connecting part, and the connecting part is welded to the side wall of the track 1. When the sliding adjustment is realized in this way, the horizontal linear adjustment is ensured to avoid the occurrence of the jamming phenomenon.

[0060] 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.
