DETAILED DESCRIPTION

[0027] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0028] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] like Figure 1 and Figure 2 As shown, this embodiment discloses a pipe assembly welding tool, which includes multiple supporting mechanisms. When welding, the pipes are placed on the multiple supporting mechanisms, and the pipes can rotate on the supporting mechanisms for welding.

[0032] The support mechanism includes a base 1 , which is a rectangular plate-shaped structure with a certain support area. When the base 1 is in contact with the ground, it provides stable support for the support mechanism.

[0033] A base 2 is provided at the top center of the base 1, and a fixed wheel group and a moving wheel group are provided on the base 2. A slide groove 11 is provided on the base 2, and the moving wheel group slides in the slide groove 11, so that the moving wheel group is slidably connected to the base 2. The sliding of the moving wheel group can adjust the distance between it and the fixed wheel group, so that the distance between the fixed wheel group and the moving wheel group is adapted to the outer diameter of the pipeline.

[0034] The fixed wheel assembly includes a fixed wheel support 3 provided on the base 2. The fixed wheel support 3 is in the shape of a vertical column. A fixed guide wheel 5 is rotatably provided on the top side wall of the fixed wheel support 3.

[0035] The moving wheel assembly includes a moving wheel support 4 slidably arranged in a sliding groove 11. The moving wheel support 4 is in the shape of a vertical column. A moving guide wheel 6 is rotatably provided on the top side wall of the moving wheel support 4.

[0036] The rotation axes of the fixed guide wheel 5 and the movable guide wheel 6 are horizontal and parallel to each other. The fixed guide wheel 5 and the movable guide wheel 6 are at the same horizontal height. The fixed guide wheel 5 and the movable guide wheel 6 are on the same straight line perpendicular to their rotation axes.

[0037] The fixed guide wheel 5 and the movable guide wheel 6 have the same structure, and their wheel width and outer diameter are the same. A cushion layer is also provided on the wheel wall of the fixed guide wheel 5 and the movable guide wheel 6. The cushion layer is made of rubber and has a certain elasticity. The setting of the cushion layer prevents the pipe from being in rigid contact or friction with the fixed guide wheel 5 and the movable guide wheel 6, which causes wear of the pipe. The cushion layer also increases the friction between the pipe and the fixed guide wheel 5 and the movable guide wheel 6, thereby preventing the pipe from rotating relative to the fixed guide wheel 5 and the movable guide wheel 6, and also preventing the pipe from axial displacement.

[0038] The chute 11 is horizontally formed and perpendicular to the axial direction of the fixed guide wheel 5 and the movable guide wheel 6, allowing the movable wheel support 4 to slide horizontally in a direction perpendicular to the axial direction of the fixed guide wheel 5 and the movable guide wheel 6. A horizontal guide groove 7 is provided on the side wall of the chute 11, and a guide rod 17 is slidably provided in the guide groove 7. The guide rod 17 is connected to the movable wheel support 4 in the chute 11.

[0039] The guide rod 17 outside the guide groove 7 is a screw rod. A locking nut 9 is threadedly connected to the guide rod 17. An anti-skid ring 8 is sleeved on the guide rod 17 between the locking nut 9 and the base 2. The outer wall of the base 2 outside the guide groove 7 is provided with anti-skid grooves 10 that cooperate with the anti-skid ring 8. When the locking nut 9 is loosened, the moving wheel support 4 can slide within the chute 11 to adjust the spacing between the moving guide wheel 6 and the fixed guide wheel 5. Tightening the locking nut 9 tightens the anti-skid ring 8 against the anti-skid grooves 10 on the base 2 outside the guide groove 7, securing the guide rod 17 and the moving wheel support 4 within the chute 11, and the spacing between the moving guide wheel 6 and the fixed guide wheel 5 is fixed.

[0040] According to the outer diameter of the pipeline, adjust the position of the moving wheel support 4 and fix it so that the distance between the moving guide wheel 6 and the fixed guide wheel 5 is adapted to the outer diameter of the pipeline. Place multiple support mechanisms in a straight line, and then place the pipeline on the support mechanism. The fixed guide wheel 5 and the moving guide wheel 6 support the lower outer wall of the pipeline. During the welding operation, the pipeline can roll and rotate at will, and can be operated by one person. The pipeline can maintain its own rotation by rolling on the fixed guide wheel 5 and the moving guide wheel 6, thereby maintaining the concentricity of the pipeline.

[0041] Example 2

[0042] like Figure 3 As shown, the difference between this embodiment and embodiment 1 is that auxiliary wheel sets are provided on both the moving wheel support 4 and the fixed wheel support 3.

[0043] The auxiliary wheel group includes a rotating seat 12, a support rod 13 is provided on the rotating seat 12, and an auxiliary guide wheel 14 is rotatably provided at the end of the support rod 13. The structure of the auxiliary guide wheel 14 is the same as that of the fixed guide wheel 5 and the movable guide wheel 6, and a cushion layer is also provided on its wheel wall.

[0044] A swivel seat 12 is rotatably mounted on the top sidewall of the driving wheel support 4 or the fixed wheel support 3, where the auxiliary wheel assembly is located. A torsion spring is installed between the swivel seat 12 and the driving wheel support 4 or the fixed wheel support 3. The elastic force of the torsion spring drives the swivel seat 12 to drive the support rod 13 to swing between the driving wheel support 4 and the fixed wheel support 3. A limit block 15 is provided on the outer wall of the swivel seat 12. A limit rod 16 is provided on the driving wheel support 4 or the fixed wheel support 3, where the swivel seat 12 is located, and cooperates with the limit block 15. The limit rod 16 is located on the trajectory of the limit block 15 swinging as the swivel seat 12 rotates.

[0045] The rotation axis of the swivel seat 12 is parallel to the rotation axis of the movable guide wheel 6 or the fixed guide wheel 5 , the support rod 13 is arranged perpendicular to the rotation axis of the swivel seat 12 , and the axial direction of the auxiliary guide wheel 14 is parallel to the axial direction of the fixed guide wheel 5 or the movable guide wheel 6 .

[0046] When no pipe is supported, the rotating seat 12 rotates under the elastic force of the torsion spring, driving its support rod 13 to swing. The limit block 15 contacts the limit rod 16 to limit the rotation of the rotating seat 12. After adjusting the distance between the moving wheel support 4 and the fixed wheel support 3, the pipe is placed on the fixed guide wheel 5 and the moving guide wheel 6 to support the pipe. During the process of lowering the pipe onto the moving guide wheel 6 and the fixed guide wheel 5, the auxiliary guide wheel 14 contacts the outer wall of the pipe and first swings outward. The rotating seat 12 rotates adaptively. After the pipe contacts the moving guide wheel 6 and the fixed guide wheel 5, the rotating seat 12 rotates under the elastic force of the torsion spring, through the support rod 13, so that the auxiliary guide wheel 14 maintains contact with the outer wall of the pipe. The auxiliary guide wheel 14 can further improve the stability of the pipe placed on the support mechanism.

[0047] The above embodiments are only preferred embodiments of the present invention and are not limitations on the technical solutions of the present invention. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present invention.
