[0002] The main function of pipelines is to achieve efficient transportation of gas, liquid or solid particles through a closed conveying system. They are widely used in energy, water conservancy, municipal and industrial fields. Due to the different needs of different industries, branch pipes need to be welded on the main pipeline, so the pipeline needs to be clamped.

[0003] Currently, existing welding equipment does not have corresponding clamping fixtures, making it impossible to simultaneously support and position the main pipe and straight pipe, resulting in extremely difficult pipe welding. The pipe is prone to movement during the welding process, affecting the stability of the pipe welding. Therefore, in order to better improve the stability of the clamping fixture during pipe welding, and to promote technological progress in the industry and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from the structure and application method of clamping fixtures for pipes in the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing welding equipment does not have corresponding clamping fixtures, making it impossible to simultaneously support and position the main pipe and straight pipe, resulting in extremely difficult pipe welding and easy pipe movement during the welding process, which affects the stability of pipe welding. Therefore, a pipe clamping fixture is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A pipe clamping fixture includes a base, a hinge fixedly connected to one side of the base, and a top plate fixedly connected to the other side of the hinge. The top plate is located on top of the base, and two fastening bolts are fixedly connected to the top of the base. The top ends of the fastening bolts are inserted into the top plate, and fastening nuts are threadedly connected to the top ends of the fastening bolts. An operating port is provided on the top of the base, and a connecting seat is fixedly connected to the top outer wall of the top plate. An adjusting screw is threadedly connected to one side of the connecting seat. A left clamping plate and a right clamping plate are rotatably mounted on one end of the two adjusting screws through embedded bearings, respectively. Both ends of the right clamping plate are provided with grooves, and a rotating screw is rotatably connected to the grooves through a rotating shaft. One end of the rotating screw is inserted into the left clamping plate, and a fixing nut is threadedly connected to the other end of the rotating screw.

[0006] Furthermore, the outer wall of the adjusting screw is threaded with a reverse fastening nut.

[0007] Furthermore, a knob is fixedly connected to one end of the adjusting screw, and the outer wall of the knob is provided with an anti-slip groove.

[0008] Furthermore, guide rods are fixedly connected to one outer wall of the left clamping plate and one outer wall of the right clamping plate.

[0009] Furthermore, a guide hole is provided on one side of the connector, and the guide rod is slidably inserted into the guide hole.

[0010] Furthermore, a first anti-slip pad is fixedly connected to the inner side of both the left and right clamping plates.

[0011] Furthermore, a second anti-slip pad is fixedly connected to the inner side of the base and the inner side of the top plate.

[0012] Furthermore, the base, top plate, left clamping plate, and right clamping plate are all arc-shaped structures.

[0013] The beneficial effects of this utility model are as follows: 1. The main pipe is fixed by the base and top plate, and the straight pipe is clamped by the left and right clamps converging towards the middle, thus supporting both the main pipe and the straight pipe simultaneously to facilitate subsequent welding and improve the stability of the pipe welding.

[0014] 2. By rotating the screw and inserting it into the left clamping plate, and then tightening the fixing nut, the clamping state of the left and right clamping plates is further secured, thereby better fixing the straight pipe and improving the stability of the straight pipe clamping.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-4 A pipe clamping fixture includes a base 1, a hinge 2 fixed to one side of the base 1 by bolts, and a top plate 3 fixed to the other side of the hinge 2 by bolts. The top plate 3 is set on the top of the base 1. Two fastening bolts 4 are welded to the top of the base 1. The top ends of the fastening bolts 4 are inserted into the top plate 3. The top ends of the fastening bolts 4 are threaded with fastening nuts. The top plate 3 is moved to press against the top of the main pipe, and the top ends of the fastening bolts 4 pass through the top plate 3. The top plate 3 is then fixed by the fastening bolts 4 and the fastening nuts, thereby fixing the main pipe. The top of the base 1 is provided with an operating port 5 for welding between the main pipe and the straight pipe; A connecting seat 6 is welded to the top outer wall of the top plate 3. An adjusting screw 7 is threaded to one side of the connecting seat 6. A knob 8 is welded to one end of the adjusting screw 7. A left clamping plate 9 and a right clamping plate 10 are respectively mounted on one end of the two adjusting screws 7 through embedded bearings. Turning the two knobs 8 respectively drives the two adjusting screws 7 to rotate, thereby driving the left clamping plate 9 and the right clamping plate 10 to converge towards the middle, thus clamping the straight pipe. Both ends of the right clamping plate 10 are provided with grooves 11. A rotating screw 12 is rotatably connected to the grooves 11 via a rotating shaft. One end of the rotating screw 12 is inserted into the left clamping plate 9, and a fixing nut 13 is threadedly connected to the other end of the rotating screw 12. By inserting the rotating screw 12 into the left clamping plate 9 and then tightening the fixing nut 13, the clamping state of the left clamping plate 9 and the right clamping plate 10 is further tightened, thereby better fixing the straight pipe.

[0019] The outer wall of the adjusting screw 7 is threaded with a reverse fastening nut 14. Tightening the reverse fastening nut 14 fixes the adjusting screw 7, thereby fixing the clamping state of the left clamping plate 9 and the right clamping plate 10.

[0020] The outer wall of knob 8 is provided with anti-slip grooves, which facilitates the operation of knob 8.

[0021] Guide rods 16 are welded to one outer wall of the left clamping plate 9 and one outer wall of the right clamping plate 10. A guide hole 15 is provided on one side of the connecting seat 6. The guide rods 16 are slidably inserted into the guide hole 15, thereby guiding the movement of the left clamping plate 9 and the right clamping plate 10 and improving the stability of the straight pipe clamping.

[0022] The inner sides of the left clamping plate 9 and the right clamping plate 10 are both bonded with a first anti-slip pad 17, and the inner sides of the base 1 and the top plate 3 are both bonded with a second anti-slip pad 18, thereby increasing the friction between the base 1 and the top plate 3 and the main pipe, as well as the friction between the left clamping plate 9 and the right clamping plate 10 and the straight pipe, thus preventing the main pipe and the straight pipe from sliding.

[0023] The base 1, top plate 3, left clamping plate 9, and right clamping plate 10 are all arc-shaped structures.

[0024] The working principle of this embodiment is as follows: When in use, first, place the main pipe on the base 1, then move the top plate 3 to press it on the top of the main pipe, and let the top of the fastening bolt 4 pass through the top plate 3. Then, use the fastening bolt 4 and the fastening nut to fix the top plate 3, thereby fixing the main pipe. Then, insert the straight pipe into the connection port of the main pipe. Next, turn the two knobs 8 to rotate the two adjusting screws 7, thereby causing the left clamping plate 9 and the right clamping plate 10 to converge towards the center, thus clamping the straight pipe. Then, tighten the reverse fastening nut 14 to fix the adjusting screw 7, thereby fixing the clamping state of the left clamping plate 9 and the right clamping plate 10. At the same time, the rotating screw 12 is inserted into the left clamping plate 9. Then, tighten the fixing nut 13 to further tighten the clamping state of the left clamping plate 9 and the right clamping plate 10, thereby better fixing the straight pipe. After that, the straight pipe and the main pipe can be welded. When the straight pipe and the main pipe are in use, the clamping fixture can also be used to support the main pipe and the straight pipe.

[0025] 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.
