Description

Technical Field

[0001] This utility model relates to the field of welding and processing technology for irregularly shaped pipes, and in particular to a welding and processing device for irregularly shaped pipes used in the construction of concealed works on highways. Background Technology

[0002] In the construction of highways, concealed works are a crucial link in ensuring the overall structural stability, and their construction quality directly affects the long-term safety and service life of the highway. As an important component of concealed works, the welding quality of irregularly shaped pipes is particularly critical.

[0003] However, when welding traditional irregular-shaped pipes, multiple special structures are often required to limit the pipes, especially when welding two C-shaped pipes. Multiple limiting structures are often needed to limit the C-shaped pipes, resulting in low welding efficiency for C-shaped pipes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies in the inconvenience of clamping and limiting C-shaped pipes during welding and processing, and to propose a welding and processing device for C-shaped pipes used in the construction of concealed works on highways.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding and processing device for irregularly shaped pipes used in the construction of concealed works for highways, comprising:

[0007] Workbench;

[0008] A base is disposed on the workbench and has a plurality of threaded holes.

[0009] A double-sided clamping mechanism is provided on the base and is used to simultaneously limit and clamp the interior of two C-shaped tubes;

[0010] A push-pull component is provided at the bottom of the workbench. The push-pull end of the push-pull component passes through the workbench and the base in sequence. The push-pull end of the push-pull component is connected to the double-sided pressing mechanism. The push-pull component is used to drive the double-sided pressing mechanism to simultaneously limit and press the interior of the two C-shaped tubes.

[0011] In one feasible solution, the bilateral clamping mechanism includes:

[0012] A first mounting base is disposed on the base, and the first mounting base is provided with two connecting ears;

[0013] A second mounting base is disposed on the base and has a connecting lug. The second mounting base is disposed opposite to the first mounting base.

[0014] Three clamping blocks, the three clamping blocks are hook-shaped, and the three clamping blocks are rotatably connected to the connecting ears on the first mounting base and the second mounting base respectively. The clamping blocks are used to limit and clamp the C-shaped pipe inside the C-shaped pipe.

[0015] A push-pull block is disposed between the first mounting base and the second mounting base. The push-pull block is hinged to the three clamping blocks respectively, and the push-pull block is connected to the push-pull end of the push-pull component.

[0016] In one feasible solution, the clamping block includes:

[0017] A connecting strip, wherein the connecting strip is vertically arranged, one end of the connecting strip is rotatably connected to the connecting lug, and the other end of the connecting strip is hingedly connected to the push-pull block;

[0018] The clamping claw is hook-shaped and is located on one side of the connecting strip. The clamping claw is located away from the connecting lug and is used to limit and clamp the inside of the C-shaped tube using the hook-shaped structure.

[0019] In one feasible solution, the connecting strip and the clamping claw are integrally formed.

[0020] In one feasible solution, the push-pull component is any one of an electric push rod, a pneumatic push rod, and a hydraulic push rod.

[0021] In one feasible solution, the base is provided with a plurality of threaded holes, and the first mounting base and the second mounting base are respectively detachably connected to the base through connectors and threaded holes.

[0022] The beneficial effects of this utility model are as follows:

[0023] This invention utilizes a push-pull component to drive a double-sided clamping mechanism, achieving synchronous limiting and clamping of the interior of two C-shaped pipes. This means the processing device eliminates the need for multiple limiting structures to clamp multiple C-shaped pipes. Consequently, it effectively overcomes the inconvenience of clamping and limiting C-shaped pipes during welding processing in existing technologies. Attached Figure Description

[0041] Example: Refer to Figures 1 to 5In this embodiment, to address the inconvenience of clamping and limiting C-shaped pipes during welding, particularly for widening two C-shaped pipes 6 by adding a welding plate 61 between them, this invention provides a welding device for concealed works on highways. The device includes a worktable 1, a base 11, a push-pull component 2, and a double-sided clamping mechanism 4. The worktable 1 has a column (not shown in the figure) at its bottom and serves as the welding surface. The base 11 is mounted on the worktable 1 and has several threaded holes. The double-sided clamping mechanism 4 is mounted on the base 11 and simultaneously clamps and limits the internal structure of the two C-shaped pipes 6, facilitating welding. The push-pull component 2 is disposed at the bottom of the workbench 1. The push-pull end of the push-pull component 2 passes through the workbench 1 and the base 11 in sequence. The push-pull end of the push-pull component 2 is connected to the double-sided clamping mechanism 4. The push-pull component 2 is used to drive the double-sided clamping mechanism 4 to simultaneously limit and clamp the interior of the two C-shaped tubes 6. That is, in this embodiment, the processing device uses the push-pull component 2 to drive the double-sided clamping mechanism 4 in linkage, thereby realizing the synchronous limiting and clamping of the interior of the two C-shaped tubes 6. That is, this processing device does not require multiple limiting structures to limit and clamp multiple C-shaped tubes 6. This effectively solves the disadvantage of the inconvenience of clamping and limiting C-shaped tubes in the welding processing of existing technologies. In addition, it should be noted that in order for the processing device to adapt to the synchronous limiting and clamping of two C-shaped tubes 6 of different thicknesses, pads 7 can be provided on both sides of the base 11. The pads 7 are used to raise the two C-shaped tubes 6 so that the double-sided clamping mechanism 4 can synchronously limit and clamp the two C-shaped tubes 6.

[0042] Reference Figure 2 and Figure 3In this embodiment, to facilitate understanding of how the push-pull component 2 drives the double-sided clamping mechanism 4 to achieve synchronous limiting and clamping of the two C-shaped pipes 6, the following description is provided. Specifically, the double-sided clamping mechanism 4 includes: a first mounting base 3, a second mounting base 5, a push-pull block 41, and a clamping block 43. The first mounting base 3 is disposed on the base 11 and has two connecting ears (not shown in the figure). The first mounting base 3 is located inside one side of one C-shaped pipe 6. The second mounting base 5 is disposed on the base 11 and has one connecting ear (not shown in the figure). The second mounting base 5 is located inside the other C-shaped pipe 6 and is positioned opposite to the first mounting base 3. The clamping block 43 is hook-shaped, and the three clamping blocks 43 are rotatably connected to the connecting ears on the first mounting base 3 and the second mounting base 5, respectively. The clamping blocks 43 are used to limit and clamp the C-shaped pipes 6 inside the C-shaped pipes 6. The push-pull block 41 is disposed between the first mounting base 3 and the second mounting base 5. The push-pull block 41 is hingedly connected to the three clamping blocks 43 respectively. The push-pull block 41 is connected to the push-pull end of the push-pull member 2. The push-pull end of the push-pull member 2 drives the push-pull block 41 to adjust its height, so that the push-pull block 41 simultaneously drives the three clamping blocks 43 to rotate hingedly, thereby allowing the hook-shaped structure on the clamping block 43 to simultaneously limit and clamp the two C-shaped pipes 6. Specifically, the clamping block 43 includes: a connecting strip 431 and a clamping claw 432. The connecting strip 431 is vertically arranged, one end of the connecting strip 431 is rotatably connected to the connecting ear, and the other end of the connecting strip 431 is hingedly connected to the push-pull block 41 through a hinge member 42. The clamping claw 432 is hook-shaped and is located on one side of the connecting strip 431, away from the connecting lug. The clamping claw 432 is used to limit and clamp the interior of the C-shaped pipe 6 using its hook-shaped structure. In this embodiment, one end of the connecting strip 431 in the three clamping blocks 43 can be hinged to the connecting lug on the first mounting base 3 and the second mounting base 5, respectively. The other end of the connecting strip 431 in the three clamping blocks 43 is hinged to the push-pull block 41 via three hinge members 42, so that the push-pull member 2 drives the push-pull block 41 to simultaneously allow the clamping claw 432 to limit and clamp the interior of the two C-shaped pipes 6. In this embodiment, to ensure the clamping strength of the clamping blocks 43, the connecting strip 431 and the clamping claw 432 are integrally formed. It should be noted that the number of clamping blocks 43 can be set according to actual needs, that is, two clamping blocks 43, three clamping blocks 43 and four clamping blocks 43 can be set. Correspondingly, the number of connecting ears on the first mounting base 3 and the second mounting base 5 also needs to be modified.

[0043] In this embodiment, the push-pull component 2 can be any one of an electric push rod, a pneumatic push rod, and a hydraulic push rod, and can be selected according to the actual situation.

[0044] In this embodiment, to accommodate different welding size requirements, the base 11 is provided with several threaded holes. The first mounting base 3 and the second mounting base 5 are detachably connected to the base 11 via connectors 51 and threaded holes, respectively. That is, the first mounting base 3 and the second mounting base 5 are detachably connected to the base 11 via the threaded holes and connectors 51. This detachable connection design between the first mounting base 3 and the second mounting base 5 and the base 11 via threaded holes allows for quick adaptation to different welding requirements, significantly improving the welding efficiency and construction quality of irregularly shaped pipes in highway concealed works.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
