[0001] This utility model relates to the field of auxiliary devices for pipe welding, and more specifically, to a special pipe connector for the reverse installation method of large-diameter pipes in wells. Background Technology

[0002] In the construction of building electromechanical systems, especially in the field of centralized air conditioning systems, there are many vertical and radial pipe welding operations in pipe shafts. This construction process not only has high welding requirements, but also makes pipe alignment extremely difficult and time-consuming, affecting the construction progress. Especially when the pipes are large in diameter and long in distance, misalignment affects the quality of the joint welding. Therefore, forced alignment and correction are sometimes performed during construction. This not only damages the pipes, but also causes quality problems at the welded ends, resulting in economic losses. Utility Model Content

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-4As shown in the embodiment, a special pipe connector for the inverted installation method of large-diameter pipes in wells is provided, including two clamping frames 1, which are hinged together by a rotating rod 2. A rubber pad 3 is provided on the inner side of the clamping frame 1, and a fixing member 4 is provided on the clamping frame 1. The fixing member 4 includes an adjusting bolt 41 and a fixing plate 42. The fixing plate 42 is located on the inner side of the clamping frame 1. The adjusting bolt 41 passes through the clamping frame 1 and is rotatably connected to the fixing plate 42, and the adjusting bolt 41 is threadedly engaged with the clamping frame 1.

[0016] In use, place the two pipes to be welded between the two clamping frames 1, and then rotate the two clamping frames 1 together. The rubber pads 3 on the inner side of the clamping frames 1 clamp the pipes, aligning and fixing the ends of the two pipes, facilitating welding. If the ends of the two pipes are not aligned after fixing, rotate the adjusting bolt 41 to push the fixing plate 42, which in turn pushes the pipes to align them. The entire process is quick and convenient, significantly improving the quality of the weld.

[0017] Furthermore, it also includes a quick clamp 5 for fixing. A connecting plate is provided on one side of the rotating rod 2 of the clamping frame 1. The connecting plates on the two clamping frames 1 are fitted together. The quick clamp 5 includes a fixing bolt 52 and a fixing nut 51. The fixing nut 51 is fixed to one of the connecting plates, and the fixing bolt 52 is threaded to the other connecting plate, with the fixing bolt 52 and the fixing nut 51 threadedly engaged. After the two clamping frames 1 are closed, fixing is achieved by screwing the fixing bolt 52 into the fixing nut 51.

[0018] Furthermore, the quick clamp 5 also includes a fixed cylinder 53 and an adjusting rod 54. The fixed cylinder 53 is sleeved outside the fixing bolt 52, and the adjusting rod 54 is fixed outside the fixed cylinder 53. The adjusting rod 54 facilitates the rotation of the fixing bolt 52.

[0019] Furthermore, the fixing component 4 consists of a fixing plate 42 and two adjusting bolts 41, which are rotatably connected to the fixing plate 42. By rotating the two adjusting bolts 41, the fixing plate 42 presses the pipe together to adjust the orientation of the pipe.

[0020] Furthermore, each clamp 1 is provided with two fasteners 4.

[0021] Furthermore, the rubber pad 3 is semi-circular, and rubber pads 3 are provided at both the front and rear ends of the inner side of the clamp 1. The rubber layer can buffer the contact between the clamp 1 and the pipe, preventing the pipe from being crushed.

[0022] Furthermore, the middle part of the clamping frame 1 adopts a hollow design.

[0023] Other techniques in this embodiment are based on existing technologies.

[0024] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
