Description

Technical Field

[0001] The utility model belongs to the field of pipeline installation equipment, and in particular relates to a pipeline joint device. Background Art

[0002] In engineering construction, pipeline installation is an important task. In the process of pipe docking, docking devices are generally used to fix the two pipe openings. The existing docking devices are generally composed of two arc-shaped plates, which clamp and fix the pipe openings of the two pipes, and weld the pipe openings using the welding openings opened in the middle of the arc-shaped plates. Due to the limited opening of the welding openings on the arc-shaped plates, only a certain length of the pipe opening can be welded at a time. It is necessary to release the fixation and rotate the docking device to compare with the welding points at other positions and then re-fix it, which is very inconvenient to use; and the existing docking devices can only adapt to pipes of one size. Pipes of different diameters can only be welded by replacing the docking devices of the corresponding models, which is very inconvenient to use. Utility Model Content

[0017] 5. The welder can weld the two pipe welds through the welding port opened in the middle of the matching frame. Due to the limited size of the welding port, when welding welds at different positions is required, it is only necessary to rotate the matching device so that the pressure roller abuts against the outer wall of the pipe and rotates to realize the comparison between the welding port and different weld positions, making the welding operation more convenient.

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0023] like Figure 1-2 As shown, the utility model proposes a pipe joint device, including two semi-cylindrical matching frames 2, which cooperate with each other to hold and fix the pipe openings of two pipes 1. One side of the two matching frames 2 is hinged to each other, and the other side is fixed together by a fixing member. Specifically, the opening edges of the two matching frames 2 extend outward and are provided with through holes, and the fixing frame includes a fixing bolt 3, which passes through the through hole and is locked by a nut. After the two matching frames 2 are closed, a cylindrical structure is formed, and the matching frames 2 can be effectively locked and fixed by the cooperation of the fixing bolt 3 and the fixing nut 31.

[0024] The two ends of the mating frame 2 are respectively provided with locking components for fixing the two pipes 1. The locking components include an arc plate 4, a driving member and a plurality of groups of clamping members. The clamping members are arranged at equal angles to make the force on the pipe 1 more uniform, so that the pipe 1 can be effectively clamped and fixed. The clamping member includes a swing rod 51, a sliding sleeve 52 and a pressure roller 53. The swing rod 51 on each clamping member has the same tilt direction. The arc plate 4 is concentrically arranged with the mating frame 2, and an arc guide rail 21 is also concentrically arranged on the end surface of the mating frame 2. The arc plate 4 is slidably mounted on the arc slide rail. The sliding cooperation between the arc guide rail 21 and the arc plate 4 can effectively limit the movement of the arc plate 4 and improve the structural stability of the device. One end of the swing rod 51 is rotatably mounted on the end surface of the mating frame 2 through a rotating shaft 511, a sliding sleeve 52 is rotatably connected to the arc plate 4, a middle portion of the swing rod 51 is slidingly sleeved in the sliding sleeve 52, the other end of the swing rod 51 is movably mounted in the middle portion of the port of the mating frame 2, a pressure roller 53 is mounted on the other end of the swing rod 51, and the pressure roller 53 is tangent to the surface of the circular pipe 1. The action end of the driving member mounted on the end surface of the mating frame 2 is connected to the arc plate 4.

[0025] When the arc plate 4 is driven to rotate on the arc guide rail 21 by the driving member, the corresponding swing rod 51 is driven to rotate and swing around the rotating shaft 511 through the sliding sleeve 52, so that the pressure rollers 53 at the ends of the swing rods 51 are all crimped and fixed to the outer wall of the pipe 1, and the pipe 1 can be coaxially fixed in the middle of the matching device, so that the device can adapt to the installation and fixation of pipes 1 of different diameters, and it is more convenient to use. The welder can weld the welds 10 of two pipes 1 through the welding port 20 opened in the middle of the matching frame 2. Since the size of the welding port 20 is limited, when welding welds 10 at different positions needs to be welded, it is only necessary to rotate the matching device to make the pressure roller 53 abut against the outer wall of the pipe 1 and rotate to achieve the comparison of the welding port 20 with the positions of different welds 10, making the welding operation more convenient.

[0026] In addition, a rubber resistance-enhancing layer 531 is provided on the surface of the pressing roller 53, which can not only increase the friction between the pressing roller 53 and the pipe 1 and improve the crimping stability, but also avoid damaging the outer wall of the pipe 1 when fixing the pipe 1.

[0027] Specifically, the driving member includes a threaded sleeve 621, a screw rod 62 and a mounting block 22, the mounting block 22 is rotatably mounted on the end surface of the mating frame 2, one end of the screw rod 62 is rotatably mounted on the mounting block 22 and extends out of the mounting block 22 to coaxially mount a hand wheel 61, the other end of the screw rod 62 is sleeved in the threaded sleeve 621, and the connecting plate 41 fixedly connected to the arc plate 4 is rotatably connected to the threaded sleeve 621. When the hand wheel 61 rotates to drive the screw rod 62 to rotate, the threaded sleeve 621 can be moved on the screw rod 62, thereby driving the arc plate 4 to rotate through the connecting plate 41, and then driving a plurality of clamping members to move to clamp and fix the pipeline 1, making the device simpler and more convenient to fix and adjust the pipeline 1.

[0028] When using the new type of device, the two matching frames 2 are matched, and the welding port 20 is matched with the pipe port welds 10 of the two pipes 1, and locked with the fixing bolts 3 and the fixing nuts 31; then the hand wheel 61 of the driving member is rotated, and the swing rod 51 is driven to rotate by the arc plate 4, so that the pressure rollers 53 are pressed and fixed with the outer wall of the pipe 1, so that the device can adapt to the installation and use of pipes 1 with different diameters.

[0029] The welder can weld the weld seams 10 of two pipes 1 through the welding port 20; when welding the weld seams 10 at different positions, it is only necessary to rotate the jointer to make the pressure roller 53 rotate against the outer wall of the pipe 1 and switch the different welding positions of the pipe port, which is more convenient to operate.
