Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, specifically a pipeline welding tool. Background Technology

[0002] Pipelines are constructed from pipes, pipe fittings, valves, and other connecting components, and are used to transport gases, liquids, or fluids containing solid particles. During operation, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines are primarily used for water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] Pipelines can be classified into metal pipes and non-metal pipes based on their raw materials. During the manufacturing process of metal pipes, in order to increase the length of the pipes and meet a wider range of application environments, metal pipes can be connected by welding to achieve the effect of extending the pipe length.

[0004] Patent document CN219484753U describes a pipe welding tool that features a fixed base with symmetrically mounted bracket plates on top. A first rubber pad increases friction with the pipe, and a U-shaped frame is hinged to the bracket plates. With the help of fastening bolts, the stability of the connection between the U-shaped frame and the fixed base is improved. A clamping plate is provided, and with the help of a threaded rod, the position of the clamping plate can be adjusted by rotating a handwheel. With the help of a second rubber pad, friction with the pipe is increased, which helps to clamp the pipe.

[0005] However, in the process of implementing the above technical solution, the following technical problems were found:

[0006] This pipe welding tool clamps the pipe by bringing the clamping plate closer to the bracket plate. With the assistance of rubber pads, it can clamp pipes of different diameters. However, in actual application, the rubber pads may deform under pressure. After clamping the pipes, the two pipes to be welded may not be coaxial, and a certain step may appear at the pipe connection point. Utility Model Content

[0007] To overcome the shortcomings of existing pipe welding tools in practical applications, such as the deformation of rubber pads under pressure, which can easily lead to misalignment of the two pipes to be welded and a step-like appearance at the pipe connection point, this application provides a pipe welding tool. By placing the bottoms of two first pipe supports and two second pipe supports inside multiple positioning slots, and after assembling and fixing the first pipe supports, second pipe supports, and base, the two first pipe supports face each other and form a Y-shape. When the pipe to be welded is placed between the first and second pipe supports, the bottom of the pipe to be welded is supported by the first and second pipe supports, keeping the two pipes to be welded in an axially aligned state and avoiding the step-like problem caused by the two pipes not being able to maintain axial symmetry at the welding point.

[0008] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0009] A pipe welding tool includes a positioning structure and a clamping structure, wherein two positioning structures are provided;

[0010] There are two clamping structures, each located on top of the positioning structure;

[0011] Both positioning structures include two first pipe supports and two second pipe supports, with the two first pipe supports facing each other and forming a Y-shape. Both clamping structures include V-shaped buckles.

[0012] When both V-shaped fasteners are fastened to the top of the pipe to be welded from top to bottom, the bottom of the pipe to be welded is supported by the first pipe support and the second pipe support, so that the two pipes to be welded are kept in an axially aligned state.

[0013] In one possible implementation, the bottoms of the two positioning structures are provided with the same base, and the top of the two long sides of the base are provided with positioning slots; the bottoms of the two first pipe supports and the two second pipe supports on the two positioning structures are respectively located inside the multiple positioning slots and are assembled and fixed with the base.

[0014] In one possible implementation, the V-shaped buckle plate has an adapter and a fixing member at both ends. The adapter includes two seat strips, and the interior of the two seat strips is provided with a first support shaft pinned to the interior of one end of the V-shaped buckle plate. The bottom of each seat strip is welded to a round rod, and the bottom of the round rod is welded to a threaded rod. A nut is threaded to the outside of one end of the threaded rod, and a spring is sleeved to the outside of the round rod and the threaded rod. The round rod is slidably connected to the interior of the top of the first pipe support away from the base, and the spring is located between the nut and the bottom surface of the first pipe support.

[0015] In one possible implementation, the threaded rod is externally sleeved with a washer located between the bottom of the spring and the top of the threaded rod.

[0016] In one possible implementation, the fastener includes a crossbar with two parallel connecting arms integrally formed in the middle of the crossbar, perpendicular to the crossbar axis. The V-shaped buckle plate is internally pin-connected to a second support shaft at the end away from the seat bar. The two connecting arms are located on both sides of the V-shaped buckle plate at the end away from the seat bar, and the tops of the two connecting arms are respectively sleeved on the outside of the two ends of the second support shaft.

[0017] In one possible implementation, the second pipe support has a cylindrical head integrally formed on the side away from the base, the top plane of the second pipe support on the side away from the base is tangent to the curved surface of the cylindrical head, and the crossbar is hooked between the cylindrical head and the bottom surface of the second pipe support on the side away from the base.

[0018] In one possible implementation, the length of the round rod is the same as the length of the nut, and the round rod and the nut are far from the long edge of the base.

[0019] The beneficial effects of this application are as follows:

[0020] Firstly, in this solution, by placing the bottoms of the two first pipe supports and the two second pipe supports inside multiple positioning slots, after assembling and fixing the first pipe supports and the second pipe supports to the base, since the two first pipe supports and the two second pipe supports face each other and form a Y-shape, when the pipe to be welded is placed between the first pipe supports and the second pipe supports, the bottom of the pipe to be welded is supported by the first pipe supports and the second pipe supports, so that the two pipes to be welded are kept in an axially aligned state, avoiding the step problem caused by the two pipes to be welded not being able to maintain an axially symmetrical state at the welding point;

[0021] Secondly, in this solution, by controlling the V-shaped buckle plate to fasten onto the top of the pipe to be welded, the threaded rod is pulled upwards using the seat bar and round rod. The nut outside the threaded rod causes the washer to apply pressure to the spring, compressing it to the bottom of the first pipe support on the side away from the base. When one end of the control connecting arm rotates outside the second support shaft, causing the crossbar to hook between the cylindrical head and the bottom surface of the second pipe support on the side away from the base, it is beneficial to fasten the V-shaped buckle plate onto the top of the pipe to be welded, and cooperate with the first pipe support and the second pipe support to clamp and fix the pipe to be welded.

Detailed Implementation

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] Example 1:

[0028] This embodiment describes the specific structure of a pipe welding tool, as detailed in the following reference. Figures 1-3 As shown, it includes two positioning structures and two clamping structures located on top of the positioning structures respectively. Both positioning structures include two first pipe supports 2 and two second pipe supports 7. Both clamping structures include V-shaped buckles 5.

[0029] Among them, the two first pipe supports 2 are respectively set facing the two second pipe supports 7 and are in a Y shape. When the two V-shaped buckle plates 5 are fastened to the top of the pipe 1 to be welded from top to bottom, the two pipes 1 to be welded can be kept in an axially aligned state. When welding the connection point of the two pipes 1 to be welded, the step problem caused by the two pipes 1 to be welded being unable to maintain an axially symmetrical state can be avoided.

[0030] Secondly, in order to ensure the alignment of the two first pipe supports 2, such as Figure 1 and Figure 2 As shown, the bottom of the two positioning structures is provided with the same base 8. The top of the two long sides of the base 8 is provided with positioning slots 6. The bottoms of the two first pipe supports 2 and the two second pipe supports 7 on the two positioning structures are respectively located inside the multiple positioning slots 6. After being assembled and fixed with the base 8, it can be ensured that the multiple second pipe supports 7 are arranged in the same straight line and the multiple positioning slots 6 are arranged in the same straight line, avoiding the situation of tilting.

[0031] The above design places the bottoms of the two first pipe supports 2 and the two second pipe supports 7 inside the multiple positioning slots 6 respectively. After the first pipe supports 2, the second pipe supports 7 and the base 8 are assembled and fixed, it can be ensured that the multiple second pipe supports 7 and the multiple positioning slots 6 are arranged on the two long sides of the base 8 in a straight line.

[0032] In this state, since the two first pipe supports 2 are respectively facing the two second pipe supports 7 and are arranged in a Y shape, when the pipe to be welded 1 is placed between the first pipe supports 2 and the second pipe supports 7, it can be supported by the Y shape. The bottom of the pipe to be welded 1 is supported by the first pipe supports 2 and the second pipe supports 7, so that the two pipes to be welded 1 are kept in an axially aligned state, avoiding the step problem caused by the two pipes to be welded 1 not being able to maintain an axially symmetrical state at the welding point.

[0033] Example 2:

[0034] Based on Example 1, this example describes the specific structure of the V-shaped buckle plate 5. The two ends of the V-shaped buckle plate 5 are respectively provided with an adapting part and a fixing part. The adapting part includes two seat strips 3. The inside of the two seat strips 3 is provided with a first support shaft 4 pinned to the inside of one end of the V-shaped buckle plate 5. The bottom of the two seat strips 3 is welded to a round rod 12. The bottom of the round rod 12 is welded to a threaded rod 16. The external thread of one end of the threaded rod 16 is connected to a nut 14 (the length of the round rod 12 and the length of the nut 14 are the same, and the round rod 12 and the nut 14 are far away from the long edge of the base 8, which can avoid interference between one end of the threaded rod 16 and the base 8 during the up and down movement of the round rod 12). The round rod 12 and the threaded rod 16 are externally sleeved to a spring 13.

[0035] The fastener includes a crossbar 10, with two parallel connecting arms 9 integrally formed in the middle of the crossbar 10 and perpendicular to the axis of the crossbar 10. The V-shaped buckle 5 is internally pin-connected to the end away from the seat bar 3, and the second pipe support 7 has an integrally formed cylindrical head 17 on the side away from the base 8. The top plane of the side of the second pipe support 7 away from the base 8 is tangent to the curved surface of the cylindrical head 17.

[0036] Among them, the round rod 12 is slidably connected to the inside of the top of the first pipe support 2 away from the base 8, while the spring 13 is located between the nut 14 and the bottom surface of the first pipe support 2. When the V-shaped buckle 5 is fastened to the top of the pipe 1 to be welded, the two seat bars 3 can be pulled by the V-shaped buckle 5 to compress the spring 13 at the bottom of the first pipe support 2 away from the base 8, thereby performing the positioning work of the pipes 1 to be welded with different diameters.

[0037] Secondly, to facilitate adjustment of the threaded connection between nut 14 and threaded rod 16, such as... Figure 3 As shown, the threaded rod 16 is externally connected to a washer 15. By placing the washer 15 between the bottom of the spring 13 and the top of the threaded rod 16, contact between the nut 14 and the spring 13 can be avoided during the loosening or tightening of the nut 14, and the spring 13 can be tightened by friction.

[0038] Furthermore, by positioning the two connecting arms 9 on either side of the V-shaped buckle plate 5 away from the seat bar 3, when the tops of the two connecting arms 9 are respectively fitted onto the outside of both ends of the second support shaft 11, the V-shaped buckle plate 5 can be controlled to fasten onto the top of the pipe 1 to be welded. The seat bar 3 and the round rod 12 are used to compress the spring 13 at the bottom of the first pipe support 2 away from the base 8, so that the crossbar 10 is hooked between the cylindrical head 17 and the bottom surface of the second pipe support 7 away from the base 8, thereby achieving the fixing effect of the V-shaped buckle plate 5 away from the seat bar 3 and the second pipe support 7 away from the base 8.

[0039] The above design controls the V-shaped buckle plate 5 to fasten onto the top of the pipe 1 to be welded. The seat bar 3 and the round rod 12 pull the threaded rod 16 upward. The nut 14 outside the threaded rod 16 causes the washer 15 to apply pressure to the spring 13, compressing it to the bottom of the first pipe support 2 on the side away from the base 8. When one end of the control connecting arm 9 rotates outside the second support shaft 11, the crossbar 10 hooks between the cylindrical head 17 and the bottom surface of the second pipe support 7 on the side away from the base 8. This allows the V-shaped buckle plate 5 to fasten onto the top of the pipe 1 to be welded and, together with the first pipe support 2 and the second pipe support 7, clamp and fix the pipe 1 to be welded. The operation is simple and quick.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
