Description

Technical Field

[0001] The utility model relates to the technical field of pipeline clamps, in particular to a pipeline clamp used for installing a pipeline welding robot. Background Art

[0002] Oil and natural gas are vital energy sources for modern society and are primarily transported through pipelines. With the accelerating pace of production in the energy industry, oil and gas pipeline network construction faces the urgent need to improve pipeline quality and, more importantly, efficiency. To ensure precision and efficiency in pipeline welding, pipeline welding robots are widely used in industrial production. However, due to the ever-changing shapes and sizes of pipelines, pipeline welding robots often require precise positioning and fixation of each pipeline during operation, placing high demands on the pipe clamps used to mount them.

[0003] Traditional pipe clamps still rely heavily on manual labor. During installation, workers must manually adjust the clamp's position and tightening force to prevent the pipe from shifting during welding. However, due to the complex and varied shapes and sizes of pipes, manual operation often struggles to achieve high-precision positioning, making it difficult to guarantee weld assembly accuracy. This labor-intensive operation method also has a low degree of automation, impacting weld quality and efficiency. Utility Model Content

[0004] In response to the above-mentioned problems in the prior art, the utility model provides a pipe clamp for installing a pipe welding robot, which solves the problem of low installation efficiency of the existing pipe clamps due to the need for manual adjustment and clamping during installation.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A pipe clamp for installing a pipe welding robot is provided, comprising a positioning frame for positioning the pipe, two arc-shaped clamps being hinged on the positioning frame, at least one hydraulic cylinder for adjusting the angle between the two arc-shaped clamps being provided between the two arc-shaped clamps, and a track mounting seat being provided on one end face of each of the two arc-shaped clamps, each track mounting seat being in the shape of a semi-disc structure and a track for moving the pipe welding robot being provided on the outer end face of each track mounting seat.

[0007] The working principle of this solution is to lift the positioning frame onto the pipeline through an external lifting device, and use the positioning frame to play a role in rough positioning. Start the hydraulic cylinder to drive the two arc-shaped clamps to close on the pipeline to clamp the pipeline, ensuring that the pipeline will not deviate during welding. After the two arc-shaped clamps clamp the pipeline, the track on the track mounting seat is coaxial with the pipeline, so that the pipeline welding robot can move directly on the track for welding. This solution automatically clamps the pipeline through the hydraulic cylinder, thereby improving the clamping and installation efficiency, and facilitates the pipeline welding robot to move for welding through the track on the track mounting seat, thereby improving welding efficiency and welding quality.

[0008] Furthermore, a lifting beam is provided on the top of the positioning frame, and lifting ears for connecting to an external lifting device are provided on both sides of the top of the lifting beam. The provision of the lifting ears facilitates the connection of the lifting beam to the external lifting device.

[0009] Furthermore, fixing rods are fixed on both sides of the bottom of the lifting beam, positioning rods are fixed on the bottom of the two fixing rods, and oblique rods tangent to the annular surface of the pipeline are arranged on both sides of each positioning rod. The tangency of the oblique rods facilitates rough positioning.

[0010] Furthermore, a hinge shaft is provided between the two fixing rods, and the two arc-shaped clamping plates are hinged to the hinge shaft.

[0011] Furthermore, hinge plates are provided on both sides of the top of each curved splint. The two hinge plates on each curved splint are hinged to the two ends of the hinge shaft, and the two adjacent hinge plates on each curved splint are fixedly connected by a hydraulic cylinder. The angles of the hinge plates at both ends are adjusted by the hydraulic cylinder to facilitate the opening and closing of the two curved splints.

[0012] Furthermore, at least one hinge plate is provided with a limit plate, which is provided with a limit slot for limiting the angle range of the hinge plate. The setting of the limit plate facilitates limiting the opening angle and closing angle of the two arc-shaped clamping plates.

[0013] Furthermore, each hydraulic cylinder is provided with a pressure sensor, and each pressure sensor and each hydraulic cylinder are electrically connected to the host computer. The provision of the pressure sensor facilitates monitoring the thrust of the hydraulic cylinder, avoids overload, and ensures clamping safety.

[0014] Furthermore, each arc-shaped splint is provided with a plurality of openings, which are helpful in reducing the weight of the arc-shaped splint and achieving a lightweight structure.

[0015] Furthermore, a rubber gasket is provided on the inner annular surface of each rail mounting seat. The rubber gasket has a certain elastic deformation when clamped, which can increase the friction between the rail mounting seat and the pipeline, prevent the pipeline from sliding, and protect the pipeline at the same time.

[0016] Furthermore, there is a 40-60 mm gap between two adjacent sides of the bottom of the two track mounting bases in the closed state. The setting of the gap can prevent the track mounting bases from being over-positioned when closing and clamping the pipe.

[0017] The utility model provides a pipeline clamp for installing a pipeline welding robot, which has the following beneficial effects:

[0018] 1. The utility model not only automatically clamps the pipe through the hydraulic cylinder, thereby improving the clamping efficiency, but also facilitates the movement of the pipe welding robot for welding through the rail on the rail mounting seat, thereby improving the welding efficiency and welding quality.

[0019] 2. The utility model can ensure the safety of clamping by setting the limit plate and the pressure sensor, and at the same time avoid damage to the pipeline through the distance between the rubber gasket and the bottom of the track mounting seat.

[0020] 3. The utility model realizes lightweight structure by providing multiple openings and removing materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The specific implementation methods of the present invention are described below to facilitate understanding of the present invention by those skilled in the art. However, it should be clear that the present invention is not limited to the scope of the specific implementation methods. For those skilled in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the appended claims, these changes are obvious, and all utility model creations using the concept of the present invention are protected.

[0030] This embodiment provides a pipe clamp for mounting a pipe welding robot. A hydraulic cylinder 4 drives two curved clamping plates 2 to close around the pipe to clamp the pipe, ensuring that the pipe does not shift during welding. A track coaxial with the pipe is provided on a track mounting base 3, facilitating movement of the pipe welding robot. This improves welding quality and efficiency, and addresses the low installation efficiency of existing pipe clamps due to the need for manual adjustment and clamping during installation. This is described in detail below.

[0031] refer to Figures 1 to 4 The pipeline clamp for installing the pipeline welding robot in this solution includes a positioning frame 1 and two arc-shaped clamps 2.

[0032] The positioning frame 1 is used to achieve rough positioning of the pipe clamp, and two arc-shaped clamps 2 are hinged on the positioning frame 1. Two hydraulic cylinders 4 for adjusting the angle are arranged between the two arc-shaped clamps 2, and a track mounting seat 3 is arranged on one side end face of the two arc-shaped clamps 2. Each track mounting seat 3 has a semi-disc structure and a track 31 for moving the pipe welding robot is arranged on the outer end face of each track mounting seat 3.

[0033] In this embodiment, the pipeline welding robot is an existing technology, so this embodiment will not further describe its specific working principle and connection relationship.

[0034] Specifically, refer to Figure 1 and Figure 2 The specific structure of the positioning frame 1 is shown in FIG. A lifting beam 11 is provided on the top of the positioning frame 1. Lifting ears for connecting to external lifting devices are provided on both sides of the top of the lifting beam 11. The lifting beam 11 is a key mechanism for bearing the weight of the pipe clamp. The maximum static stress of the lifting beam 11 in this embodiment is 1.324×108N / m 2 , ensuring structural strength.

[0035] The bottom of the lifting beam 11 is fixed with fixed rods 13 on both sides, and the bottoms of the two fixed rods 13 are fixed with positioning rods 14. The two sides of each positioning rod 14 are provided with oblique rods tangent to the annular surface of the pipeline. The tangency of the oblique rods facilitates rough positioning.

[0036] A hinge shaft 12 is provided between the two fixing rods 13 , and the two arc-shaped clamping plates 2 are hinged to the hinge shaft 12 .

[0037] Specifically, the specific structure of the arc splint 2 can refer to Figure 2 Each curved splint 2 is provided with hinged plates 21 on both sides of its top. The two hinged plates 21 on each curved splint 2 are hingedly connected to the ends of the hinge shaft 12, and the two adjacent hinged plates 21 on each curved splint 2 are fixedly connected by a hydraulic cylinder 4. In this embodiment, the thrust of the hydraulic cylinder 4 is greater than 6 tons. The hydraulic cylinder 4 is used to adjust the angle of the hinged plates 21 at both ends, thereby facilitating the opening and closing of the two curved splints 2.

[0038] In order to limit the opening and closing angles of the two arc-shaped splints 2, refer to Figure 5 A limiting plate 22 is provided on one of the hinge plates 21 , and a limiting groove is provided on the limiting plate 22 , and both sides of the limiting groove can limit the hinge plate 21 located therein.

[0039] At the same time, in order to facilitate monitoring the thrust of the hydraulic cylinder 4, avoid overload, and ensure clamping safety, a pressure sensor is provided in each hydraulic cylinder 4. The pressure sensor and the hydraulic cylinder 4 can be electrically connected to a host computer, which can be a PLC electrically connected to a display screen.

[0040] In this embodiment, to achieve a lightweight structure, the curved plates 2 are made of profiles and plates, and each is provided with multiple openings. The multiple openings help reduce the weight of the curved plates 2. The wire feeder and wire box of the pipe welding robot can be directly fixed to the curved plates 2.

[0041] As a further solution of this embodiment, in order to protect the pipeline, a rubber gasket is provided on the inner annular surface of each track mounting seat 3. The rubber gasket has a certain elastic deformation when clamped, which can increase the friction between the track mounting seat 3 and the pipeline, prevent the pipeline from sliding, and protect the pipeline at the same time. Figure 6 , and there is a 40-60mm gap between the two adjacent sides of the bottom of the two rail mounting bases 3 when they are closed. In this embodiment, the gap is preferably 50mm. The setting of the gap can prevent the rail mounting bases 3 from being over-positioned when closing and clamping the pipe.

[0042] In summary, the working principle of this solution is: the positioning frame 1 is hoisted onto the pipeline through an external lifting device, referring to Figure 6 and Figure 7 , start the hydraulic cylinder 4 to drive the two arc-shaped clamps 2 to close on the pipe to clamp the pipe, ensuring that the pipe will not deviate during welding. After the two arc-shaped clamps 2 clamp the pipe, the track on the track mounting seat 3 is coaxial with the pipe, so that the pipe welding robot can move on the track to perform laser scanning and welding.

[0043] Although the specific embodiments of the utility model are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
