Pipe alignment is the most basic step in pipeline installation, and it has high requirements for welding quality, worker skills, and working environment. However, existing alignment tools are not suitable for aligning small and medium diameter pipes and cannot adapt to the needs of different pipe diameters. Conventional alignment tools have poor compatibility with pipes. Utility Model Content
[0003] In order to solve the problems existing in the prior art, the present invention provides a portable compression pipe fitting device.
[0004] The portable compression-type pipe fitting device provided by this utility model adopts the following technical solution:
[0005] A portable compression pipe fitting device includes a frame, a positioning mechanism at the bottom of the frame, and a tightening mechanism at the top of the frame. The positioning mechanism includes a positioning rod for supporting and positioning the pipe. The positioning rod is arranged in a V-shape with the V-shaped opening facing upward. The tightening mechanism includes a pressure block for applying downward pressure to the pipe and a driving component for driving the pressure block to move up and down. The pressure block cooperates with the positioning rod to fix the pipe.
[0006] By adopting the above technical solution, both pipe sections are placed on the positioning mechanism. Under the oblique support of the two positioning rods, the pipes are stably positioned on the vertical centerline of the frame. Because the two positioning rods are arranged in a V-shape, the positioning mechanism can adapt to pipes of different diameters. The liftable pressure block works with the positioning rods to fix the pipes. This matching device is suitable for the butt welding needs of various pipe diameters, such as medium and small diameter pipes. It not only improves the adaptability of the matching device to various types of pipes, but also makes it convenient to carry and transport, and is simple and efficient to operate.
[0007] Optionally, the frame includes a mounting rod located above the pipe, a drive assembly mounted on the mounting rod, the drive assembly including an adjusting rod that rotates through the mounting rod, a lifting pipe threaded to the bottom of the adjusting rod, the lifting pipe having a polygonal cross-section, a guide pipe fixed to the mounting rod on the outside of the lifting pipe, and a pressure block located at the bottom of the lifting pipe.
[0008] By adopting the above technical solution, rotating the adjusting rod can drive the lifting tube to move up and down, thereby driving the pressure block to move up and down, making the drive component easy to operate.
[0009] Optionally, a top plate is connected to the bottom of the lifting pipe, and pressure blocks are installed at both ends of the top plate, with the pressure blocks symmetrically arranged on the left and right sides of the lifting pipe.
[0010] By adopting the above technical solution, multiple pressure blocks are applied to both sides of the top of the pipe, making the pipe more stable after being compressed.
[0011] Optionally, a connecting screw is fixed to the top plate, and the connecting screw is threadedly connected to the lifting pipe.
[0012] By adopting the above technical solution, it is convenient to replace and maintain the pressure block and the top plate.
[0013] Optionally, a mounting bracket is fixed to the side of the mounting rod away from the pipe, an adjusting rod passes through the mounting bracket and the mounting rod, and two clamps are fitted and fixed to the mounting rod, with the clamps located on the upper and lower sides of the mounting bracket.
[0014] By adopting the above technical solution, the mounting bracket and clamping plate work together to ensure that the adjusting rod can only rotate circumferentially and cannot move axially, thus guaranteeing its range of motion.
[0015] Optionally, the compressed block can be spherical or cylindrical.
[0016] Optionally, one end of the mounting rod is rotatably connected to other structures of the frame, and the other end of the mounting rod is detachably connected to other structures of the frame.
[0017] By adopting the above technical solution, the installation rod can be rotated and opened, and various pipe-laying methods can be used, such as horizontal insertion into the pipe or vertical placement into the pipe, to adapt to different construction scenarios.
[0018] Optionally, the positioning mechanism may also include a support rod, the top of which is fixed to the middle of the positioning rod, and the bottom of which is fixed to the frame.
[0019] By adopting the above technical solution, the support rod provides support for the positioning rod, which can effectively avoid the problem of the positioning rod being deformed under pressure. Attached Figure Description

[0025] The following combination Figures 1-4 The present invention will be described in further detail below.
[0026] This utility model discloses a portable compression-type pipe fitting device. (Refer to...) Figure 1 and Figure 2 A portable compression pipe fitting device is used to fix pipe 1 during the docking process of two pipe sections 1. After the docking end faces of the two pipe sections 1 are welded, a weld seam 10 is formed. The fitting device includes a frame 2, a positioning mechanism 3 and a tightening mechanism 4.
[0027] Reference Figure 1 and Figure 3 The frame 2 is a rectangular frame structure. The frame 2 includes multiple base rods 20 that are fixed in both longitudinal and transverse directions. The top surface of the longitudinally arranged base rods 20 is vertically fixed with vertical rods 21, and the top surface of the vertical rods 21 is fixed with top rods 22. An installation rod 23 is provided between two adjacent top rods 22. In this embodiment, one end of the installation rod 23 is hinged to one top rod 22, and the other end is detachably connected to another top rod 22 by a pin or bolt. The top rod 22 is provided with an operating space for the pin or bolt according to the usage requirements.
[0028] Reference Figure 2 The positioning mechanism 3 is located between the horizontally arranged bottom rod 20 and the vertical rods 21 located on both sides of it. The positioning mechanism 3 includes a positioning rod 30 and a support rod 31. There are two positioning rods 30 arranged in a V-shape with the V-shaped opening facing upward. The top of the positioning rod 30 is fixed to the vertical rod 21, and the bottom of the positioning rod 30 is fixed to the middle of the bottom rod 20. The top of the support rod 31 is fixed to the middle of the positioning rod 30, and the bottom of the support rod 31 is fixed to the connection between the vertical rod 21 and the bottom rod 20.
[0029] Reference Figure 2 and Figure 4The clamping mechanism 4 is mounted on the mounting rod 23. The clamping mechanism 4 includes a mounting frame 40 fixed to the middle of the top surface of the mounting rod 23. The mounting frame 40 is U-shaped with the U-shaped opening facing downward. An adjusting rod 41 is vertically inserted through the middle of the mounting frame 40. A handle 42 for rotating the adjusting rod 41 is installed at the top of the adjusting rod 41. The adjusting rod 41 has external threads on its peripheral wall. Two clamping plates 43 are also fitted and fixed on the adjusting rod 41. The two clamping plates 43 are located on the upper and lower sides of the middle of the mounting frame 40 to limit the axial movement of the adjusting rod 41.
[0030] Reference Figure 4 A lifting tube 44 is provided on the side of the mounting rod 23 away from the mounting frame 40. The lifting tube 44 has an internal thread and is threaded to the adjusting rod 41. The lifting tube 44 has a rectangular cross-section. A guide tube 45 is sleeved on the outside of the lifting tube 44. The internal shape of the guide tube 45 is adapted to the lifting tube 44. The guide tube 45 is fixed to the mounting rod 23. A top plate 46 is provided on the side of the lifting tube 44 away from the mounting rod 23. The top plate 46 is arc-shaped and the arc opening faces the side away from the mounting rod 23.
[0031] Reference Figure 4 A connecting screw 47 is vertically fixed to the center of the top surface of the top plate 46. The connecting screw 47 is threadedly connected to the lifting pipe 44. A spherical or cylindrical pressure block 48 is fixedly installed at each end of the top plate 46. The pressure block 48 is used to contact the pipe 1 and apply pressure. In order to reduce the deformation of the pipe 1 under pressure, the material of the pressure block 48 can be selected according to the actual situation. For example, rubber or other suitable materials can be selected. The other components besides the pressure block 48 form a drive assembly for driving the pressure block 48 to move up and down.
[0032] The implementation principle of the portable compression pipe fitting device of this utility model embodiment is as follows: the operator can choose the specific way to place the pipe 1 on the device according to the actual working conditions. For example, the pipe 1 can be inserted horizontally into the frame 2 or vertically placed into the frame 2 after rotating and opening the mounting rod 23. After both pipe sections 1 are placed on the positioning mechanism 3, the pipe 1 is stably positioned on the vertical center line of the frame 2 by the oblique support of the two positioning rods 30. Since the two positioning rods 30 are arranged in a V-shape, the positioning mechanism 3 can adapt to pipes 1 of different diameters. The support rod 31 has an oblique support effect on the positioning rod 30, which effectively avoids the positioning rod 30 from bending under force.
[0033] Then, the handle 42 is rotated. The adjusting rod 41 is restricted by the two clamps 43 and cannot move up and down, but can only rotate. Since the adjusting rod 41 is threadedly connected to the lifting pipe 44 and is restricted by the guide pipe 45, the lifting pipe 44 can only move downward and cannot rotate. When the lifting pipe 44 moves downward, it drives the top plate 46 and the pressure block 48 to move downward until the pressure block 48 is in stable contact with the outer wall of the pipe 1. The pressure block 48, together with the positioning rod 30, stably fixes the pipe 1 in the device.
[0034] Finally, welding of the two pipe sections 1 can be performed. After welding, turn the handle 42 in the opposite direction to detach the pressure block 48 from the pipe 1. Then, move the device horizontally off the pipe 1 or remove it vertically after opening the mounting rod 23. The top plate 46 and the pressure block 48 are detachably mounted on the lifting pipe 44 via the connecting screw 47 for easy replacement and maintenance. This butt welding device is suitable for butt welding of various pipe diameters, including medium and small diameter pipes 1. It not only improves the adaptability of the butt welding device to various types of pipes 1, but also makes it convenient to carry and transport, and is simple and efficient to operate.
[0035] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
