[0039] Embodiment 1

[0040] This embodiment is the first embodiment of the present utility model. Please refer to Figures 1 to 3 , this embodiment provides a pipeline splicing tooling. The pipeline here can be the pipeline used in an asphalt distributor, or the pipeline used in other equipment or industrial sites.

[0041] If the pipeline is the pipeline used in an asphalt distributor, please refer to Figure 9 , the pipelines to be spliced include a heat-conducting oil pipe 60, an asphalt return tank branch pipe 70 and an asphalt return tank pipe 80. Among them, the heat-conducting oil pipe 60 is provided with an oil inlet flange 601 and an oil outlet flange 602, the asphalt return tank branch pipe 70 is provided with an asphalt inlet flange A 701, an asphalt outlet flange A 702, an asphalt return tank flange A 703 and an asphalt branch flange 704, and the asphalt return tank pipe 80 is provided with an asphalt inlet flange B 801, an asphalt outlet flange B 802 and an asphalt return tank flange B 803.

[0042] The pipeline splicing tooling specifically includes a tooling table 10, a positioning component 20 and a supporting component 30. The positioning component 20 and the supporting component 30 are both arranged on the upper side of the tooling table 10. Among them, both the positioning component 20 and the supporting component 30 are arranged in plurality.

[0043] Specifically, the positioning component 20 is pre-fixed on the tooling table 10 according to the shape or layout of the pipeline to be butt-welded. Each positioning component 20 at least includes a positioning plate 201, and positioning holes 2011 are formed on the positioning plate 201. The flange structure on the pipeline to be butt-welded is connected to the positioning plate 201 through the positioning holes 2011, or directly connected to the tooling table 10 through the mounting holes 101 on the tooling table 10. Different from the positioning component 20, the supporting components 30 are all slidably connected to the tooling table 10, and their function is to support the middle section of the pipeline to be butt-welded.

[0044] Therefore, please refer to Figure 8 , taking the pipeline to be butt-welded used in an asphalt distributor as an example. By setting the positioning component 20, the operator first pre-fixes each positioning component 20 on the upper side of the tooling table 10 according to the shape of the pipeline to be butt-welded in the asphalt distributor, and then positions and supports the pipeline to be butt-welded on the tooling table 10, which facilitates the operator to perform butt-welding operations, avoids redundant problems such as damage to other components caused by butt-welding at the assembly site of the asphalt distributor, improves the manufacturing and assembly efficiency of the pipeline, is conducive to the mass production of the asphalt distributor, and the butt-welding quality is greatly improved when operating on the butt-welding tooling, which can effectively ensure the dimensional accuracy and shape accuracy of the pipeline. In addition, by setting the support component 30 with adjustable position, the support center of gravity of the support component 30 for the pipeline to be butt-welded can be adjusted at any time according to the different butt-welding positions of the pipeline to be butt-welded, avoiding the falling off of the pipeline during the butt-welding process and improving the butt-welding quality.

[0045] Furthermore, please refer to Figure 4 , the positioning component 20 provided in this embodiment includes a plurality of first positioning members. In this example, the number of the first positioning members can be set to two, that is, the first positioning members are one or more of the plurality of positioning components 20. The positioning plate 201 of the first positioning member is fixedly connected to the tooling table 10, and the height of the positioning plate 201 is adapted to the flange structure to be connected thereto. The first positioning member may further include a first positioning seat 202. The first positioning seat 202 is fixedly connected to the upper side of the tooling table 10 through fasteners, and the fasteners may be bolts. The positioning plate 201 is fixedly connected to one side of the upper end surface of the first positioning seat 202. To strengthen the structural stability of the positioning plate 201, the positioning plate 201 is also fixedly connected to the first positioning seat 202 through a first rib plate 203. In addition, the positioning plate 201 may be a vertically placed rectangular plate, the first positioning seat 202 may be a horizontally placed rectangular plate, and the first rib plate 203 may be a vertically placed triangular plate.

[0046] Furthermore, please refer to Figure 5, the positioning component 20 provided in this embodiment further includes a plurality of second positioning members. In this embodiment, the number of the second positioning members can be set to three, that is, the second positioning members are also one or more of the plurality of positioning components 20. The structures of the second positioning members and the first positioning members are similar. The only difference is that there is a pair of first rib plates 203 in the second positioning members, and they are respectively fixedly connected between both sides of the positioning plate 201 and the first positioning seat 202. The reason is that the shape of the second positioning member is larger than that of the first positioning member, and greater support strength is required. In addition, other structures of the second positioning members will not be elaborated here.

[0047] Further, please refer to Figure 6 , the positioning component 20 provided in this embodiment further includes a third positioning member, that is, the third positioning member is also one of the plurality of positioning components 20. In addition to the positioning plate 201, the third positioning member further includes a support column 204, and the support column 204 is rotatably connected to the upper side of the tooling table 10. The positioning plate 201 is fixedly connected to the top end of the support column 204 and is horizontally placed to be adapted to the height of the flange structure to be connected. The third positioning member may further include a first positioning seat 202, and the first positioning seat 202 is fixedly connected to the upper side of the tooling table 10 through a fastener, and the fastener can be a bolt. The support column 204 is rotatably connected to the upper side of the first positioning seat 202, which can be achieved by fixing a convex shaft at the bottom end of the support column 204 and inserting it into the upper side of the first positioning seat 202.

[0048] Therefore, please refer to again Figure 8, and continue to take the pipeline to be joined as an example for an asphalt distributor. The inlet flange 601 and outlet flange 602 of the heat-conducting oil pipe 60 are respectively connected to a first positioning member. The asphalt inlet flange A 701, asphalt outlet flange A 702, asphalt return tank flange A 703 and asphalt distribution flange 704 of the asphalt return tank branch pipe 70 are respectively connected to a third positioning member, a second positioning member, the tooling platform 10 and a second positioning member in one-to-one correspondence. The asphalt inlet flange B 801, asphalt outlet flange B 802 and asphalt return tank flange B 803 of the asphalt return tank pipe 80 are respectively connected to a second positioning member, a second positioning member and the tooling platform 10 in one-to-one correspondence. Among them, since the asphalt return tank flange B 803 is installed downward, when it cannot directly contact the tooling platform 10, it can also be directly connected to a positioning plate 201, and the positioning plate 201 is fixedly connected to the upper side of the tooling platform 10 through fasteners, and the fasteners can be bolts. It can be seen that the flange structure on the pipeline to be joined of the asphalt distributor is connected to the positioning plate 201 through the positioning holes 2011 on the positioning plate 201, or directly connected to the tooling platform 10 through the mounting holes 101 on the tooling platform 10. Among them, by setting a rotatable third positioning member, the positioning plate 201 installed horizontally downward can be rotated to the outside of the tooling platform 10, which is convenient for the operator to take the asphalt return tank branch pipe 70 before and after the joining operation.

[0049] Furthermore, please refer to Figure 1 and Figure 7 , in the tooling platform 10 provided in this embodiment, a chute or a sliding hole is opened along the extending direction of the pipeline to be joined, and the above-mentioned support assembly 30 can slide on the upper side of the tooling platform 10.

[0050] Among them, the support assembly 30 includes a support plate 301 to be adapted to the height of the pipeline to be joined that needs to be supported, and a slider is provided on the support assembly 30, and the slider is slidably connected to the chute or the sliding hole. The support assembly 30 further includes a second positioning seat 302, the support plate 301 is supported on the second positioning seat 302 and fixedly connected to the second positioning seat 302 through a second rib plate 303, and the slider is provided at the bottom of the second positioning seat 302. In addition, the support plate 301 can be a vertically placed rectangular plate, the second positioning seat 302 can be a horizontally placed rectangular plate, and the second rib plate 303 can be a vertically placed triangular plate.

[0051] Therefore, by setting the support assembly 30 with adjustable position, the support center of gravity of the support assembly 30 for the pipeline can be adjusted at any time according to the different joining positions of the pipeline, avoiding the falling off of the pipeline during the joining process and improving the quality of the joining.

[0052] It should be noted that, continuing with the example where the pipe to be spliced is used in an asphalt distributor, the support assembly 30 can be provided below the asphalt return pipe 80, the asphalt return branch pipe 70, and the heat-conducting oil pipe 60. However, in this embodiment, since the structure of the heat-conducting oil pipe 60 is relatively simple, no support assembly 30 is provided for it. Therefore, the number of support assemblies 30 in this embodiment can be set to two.

[0053] Embodiment 2

[0054] This embodiment is the second embodiment of the present utility model. This embodiment further improves the support assembly 30 based on Embodiment 1.

[0055] Please refer to Figure 7 , in order to make the support assembly 30 have a more stable supporting effect on the pipeline, a clamping groove 3011 adapted to the pipeline is provided on the upper side of the support plate 301. At the same time, it also has the effects of limiting and damping the pipeline, and can significantly reduce the vibration during the splicing welding.

[0056] Furthermore, the clamping groove 3011 can be square or arc-shaped.

[0057] Embodiment 3

[0058] This embodiment is the third embodiment of the present utility model, and further improves the technical solution based on Embodiment 1 and Embodiment 2.

[0059] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 8 , in order to facilitate the mobile hoisting, the pipeline splicing tooling provided in this embodiment further includes a plurality of lifting lugs 40, and the lifting lugs 40 are installed at the four corners on the upper side of the tooling table 10. Among them, the lifting lugs 40 can be threadedly connected to the upper side of the tooling table 10.

[0060] Furthermore, in order to improve the structural strength of the tooling table 10, the pipeline splicing tooling provided in this embodiment further includes a reinforcing member 50, and the reinforcing member 50 is arranged on the lower side of the tooling table 10, and the welding fixation method can be selected. Among them, the reinforcing member 50 can include a plurality of flat steels connected end to end in sequence.

[0061] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0062] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principles of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
