Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, and in particular to a pipeline alignment device for pipeline engineering. Background Technology

[0002] Pipeline installation includes common pipe materials, fittings, flanges, basic pipeline installation techniques, pipeline connections, support and compensator installation, valves, building water supply and drainage pipeline installation, heating system installation, pipeline pressure testing and cleaning, common industrial pipeline installation, non-ferrous metal pipeline and stainless steel pipeline installation, common non-metallic pipeline and anti-corrosion lined pipeline installation, instrument pipeline installation, and pipeline corrosion protection and insulation. Currently, pipeline installation often requires the butt joint connection of two different pipelines. However, existing pipeline connections are basically done manually by aligning the joints, resulting in large deviations at the joints, which in turn affects the sealing performance between pipelines.

[0003] For example, the adjustable pipe-connecting device for pipeline installation disclosed in Chinese patent literature (publication number: CN209466200U) involves placing two pipes in corresponding annular clamps, rotating the wing bolt b to bring the two annular clamps closer together to clamp the pipes, and then rotating the wing bolt a to bring the interfaces of the two pipes closer together, thereby completing the alignment of the pipe interfaces. This makes it convenient for workers to connect and fix the two pipe interfaces. This utility model has the advantages of good fixing effect, accurate interface, and convenient and quick use.

[0004] However, the clamping action of the corresponding ring clamp is controlled by two wing bolts b, which requires the operator to rotate the bolts with both hands in sync to ensure that the force on both sides of the pipe is balanced. If there is a difference in the rotation speed or number of turns of the bolts on both sides, the ring clamp will tilt due to uneven force, causing the pipe to be skewed when clamped, or even causing the clamp and the pipe to jam. At this time, repeated loosening and adjustment are required, which seriously reduces the fixing efficiency of the pipe. Moreover, the docking process depends entirely on manual operation, which is very easy to cause arm fatigue, resulting in high labor costs and low efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the cumbersome process of fixing pipes during pipe connection, the large amount of labor involved, and the reduced efficiency of pipe connection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pipe alignment device for pipeline engineering includes a mounting base, wherein a docking and moving mechanism is provided inside the mounting base.

[0008] The docking and moving mechanism includes a bidirectional lead screw, the two ends of which are rotatably connected to the inner walls of the two sides of the mounting base via bearings. A worm gear is fixedly sleeved on the outside of the bidirectional lead screw, and symmetrically distributed threaded blocks are threadedly connected to the outside of the bidirectional lead screw. A symmetrically distributed guide groove is opened at the upper end of the mounting base, and a guide block is slidably connected to the inner wall of the guide groove. The lower end of the guide block is fixedly connected to the upper end of the threaded block.

[0009] A convenient fixing mechanism is provided on the top of the mounting base.

[0010] Preferably, a movable plate is fixedly connected to the upper end of the guide block, and a symmetrically distributed movable sleeve is fixedly connected to the lower end of the movable plate. A guide rail is slidably connected to the inner wall of the movable sleeve, and the lower ends of the plurality of guide rails are fixedly connected to the upper end of the mounting base.

[0011] Preferably, a servo motor is fixedly installed on the inner bottom wall of the mounting base, and a worm gear is fixedly installed on the output shaft of the servo motor through a coupling, with the outer surface of the worm gear meshing with the tooth surface of the worm wheel.

[0012] Preferably, the convenient fixing mechanism includes a mounting frame, the lower ends of the two mounting frames are symmetrically distributed and fixedly connected to the upper ends of the two movable plates respectively, and the inner bottom wall of the mounting frame is fixedly connected with symmetrically distributed V-shaped clamping bases.

[0013] Preferably, the upper end of the V-shaped clamping base is provided with an avoidance groove, and a servo electric cylinder is fixedly installed on the upper end of the mounting frame. One end of the piston rod of the servo electric cylinder passes through the inner wall of the mounting frame and is fixedly connected to a lifting plate.

[0014] Preferably, V-shaped clamping blocks that are symmetrically distributed are fixedly connected to both ends of the lifting plate, and linkage rods that are symmetrically distributed are fixedly connected to one side of each V-shaped clamping block. Lifting seats are fixedly connected to the opposite ends of each of the two linkage rods.

[0015] Preferably, the inner walls on both sides of the lifting seat are rotatably connected to auxiliary rollers via bearings, and the front of the mounting frame is provided with an observation window.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

A servo electric cylinder drives a V-shaped clamping block to cooperate with a V-shaped clamping base, which can stably clamp pipes of different diameters with precise positioning. The docking and moving mechanism is driven by a servo motor, which drives the two installation frames to move precisely relative to each other through a worm gear, worm wheel, and bidirectional lead screw, aligning the pipe interfaces.

At the same time, the device is adaptable to pipes of different diameters, has strong versatility, and ensures the quality and efficiency of pipe installation. Attached Figure Description

[0028] Example

[0029] like Figures 1-5 As shown, this utility model provides a technical solution: a pipe alignment device for pipeline engineering, including an installation base 1, which serves as the basic support component of the entire device, providing a stable installation platform for the docking and moving mechanism and the convenient fixing mechanism, and ensuring the overall stability of the device during the pipe docking process.

[0030] The mounting base 1 is internally equipped with a docking and moving mechanism, which drives two pipes to precisely approach and dock, ensuring interface alignment accuracy. The docking and moving mechanism includes a bidirectional lead screw 2, the two ends of which are rotatably connected to the inner walls of the mounting base 1 on both sides via bearings. The bearings make the bidirectional lead screw 2 rotate more smoothly and can withstand axial force, ensuring stable transmission.

[0031] The external fixed sleeve of the bidirectional lead screw 2 is fitted with a worm gear 21, which is used to cooperate with the worm 29 to transmit power, realize speed reduction and torque increase, and improve transmission accuracy. The external thread of the bidirectional lead screw 2 is connected with symmetrically distributed threaded blocks 22. When the bidirectional lead screw 2 rotates, the two threaded blocks 22 can move synchronously in opposite directions to ensure the symmetry of the movement of the pipes on both sides.

[0032] The upper end of the mounting base 1 is provided with symmetrically distributed guide grooves 23, which provide a moving track for the guide block 24. The guide block 24 is slidably connected to the inner wall of the guide groove 23. The lower end of the guide block 24 is fixedly connected to the upper end of the threaded block 22. The guide block 24 cooperates with the guide groove 23 to restrict the rotation of the threaded block 22, so that it can only move along the axial direction and ensure accurate movement direction.

[0033] A movable plate 25 is fixedly connected to the upper end of the guide block 24 to support the convenient fixing mechanism and drive it to move. A movable sleeve 26 is fixedly connected to the lower end of the movable plate 25. A guide rail 27 is slidably connected to the inner wall of the movable sleeve 26. The lower ends of the multiple guide rails 27 are fixedly connected to the upper end of the mounting base 1. The movable sleeve 26 cooperates with the guide rail 27 to further enhance the stability of the movable plate 25 when it moves, prevent it from tilting or shaking, and ensure the levelness of the pipe connection.

[0034] A servo motor 28 is fixedly installed on the inner bottom wall of the mounting base 1 to provide power for the docking and moving mechanism. Its output speed is stable, which facilitates precise control of the moving distance. A worm gear 29 is fixedly installed on the output shaft of the servo motor 28 through a coupling. The outer surface of the worm gear 29 meshes with the tooth surface of the worm wheel 21. The worm gear 29 and the worm wheel 21 form a reduction transmission mechanism, which can convert the high-speed rotation of the servo motor 28 into the low-speed rotation of the bidirectional lead screw 2, while increasing the torque to ensure that it can drive the movement of heavier pipes.

[0035] A convenient fixing mechanism is provided above the mounting base 1 for quickly and firmly clamping pipes of different diameters, providing a stable foundation for docking. The convenient fixing mechanism includes mounting frames 3, with the lower ends of the two mounting frames 3 symmetrically distributed and fixedly connected to the upper ends of the two movable plates 25, providing installation space and protection for the internal clamping components.

[0036] The inner bottom wall of the mounting frame 3 is fixedly connected with symmetrically distributed V-shaped clamping bases 31. The V-shaped structure can automatically adapt to pipes of different diameters, play a preliminary positioning role for the pipes, and has a large contact area with the pipes, making the clamping more stable.

[0037] The upper end of the V-shaped clamping base 31 is provided with a relief groove 32 to provide a space for the lower end of the V-shaped clamping block 35, so as to avoid interference between the V-shaped clamping block 35 and the V-shaped clamping base 31 when the V-shaped clamping block 35 descends, and to ensure that small-diameter pipes can be effectively clamped.

[0038] A servo electric cylinder 33 is fixedly installed at the upper end of the mounting frame 3 to provide power for the clamping action. Its extension stroke is precise and controllable, making it easy to adjust the clamping force. One end of the piston rod of the servo electric cylinder 33 passes through the inner wall of the mounting frame 3 and is fixedly connected to a lifting plate 34, which is used to drive the V-shaped clamping block 35 to rise and fall synchronously to ensure that the clamping force on both sides is uniform.

[0039] The lifting plate 34 has V-shaped clamping blocks 35 that are symmetrically distributed at both ends. These blocks, together with the V-shaped clamping base 31, form an upper and lower clamping mechanism for the pipe. The V-shaped structure can fit tightly against the outer circle of the pipe to prevent the pipe from rolling or shifting during clamping. A linkage rod 36 that is symmetrically distributed is fixedly connected to one side of the V-shaped clamping block 35. A lifting seat 37 is fixedly connected to the opposite end of each of the two linkage rods 36. This seat is used to drive the auxiliary roller 38 to rise and fall synchronously, thereby switching between the pipe pushing and clamping states.

[0040] The inner walls on both sides of the lifting seat 37 are rotatably connected to auxiliary rollers 38 via bearings. During the pipe pushing stage, the auxiliary rollers 38 are higher than the V-shaped clamping base 31. The pipe contacts the auxiliary rollers 38, converting the sliding friction between the pipe and the mounting frame 3 into rolling friction, which greatly reduces the pushing resistance and makes it easier for operators to push the pipe.

[0041] During clamping, the auxiliary roller 38 descends with the lifting seat 37, without affecting the contact and positioning of the pipe with the V-shaped clamping base 31. The front of the mounting frame 3 is provided with an observation window 39, which makes it easy for operators to observe the position and connection of the pipe, make timely adjustments, and improve the ease of operation.

[0042] The working process of this utility model:

[0043] Step 1: Place the pipe to be connected inside the mounting frame 3. Since the height of the auxiliary roller 38 is higher than the height of the inner wall groove of the V-shaped clamping base 31, the pipe will contact the auxiliary roller 38. The operator pushes the pipe, and with the help of the rotation of the auxiliary roller 38, the pipe can be easily pushed to one side of the mounting frame 3 to wait for connection. Start the servo electric cylinder 33, and its piston rod extends. Through the lifting plate 34, it drives the two V-shaped clamping blocks 35 to descend synchronously. During the descent of the V-shaped clamping blocks 35, the auxiliary roller 38 in the lifting seat 37 is driven to descend through the linkage rod 36, so that the pipe contacts and positions itself with the V-shaped inner wall of the V-shaped clamping base 31. The V-shaped clamping blocks 35 continue to descend, and their lower ends are inserted into the clearance groove 32, cooperating with the V-shaped clamping base 31 to achieve stable clamping and fixing of pipes of different diameters. Follow the same steps to clamp and fix the pipe in the other mounting frame 3.

[0044] Step two: Start the servo motor 28. The servo motor 28 drives the worm gear 29 to rotate. The worm gear 29 drives the bidirectional lead screw 2 to rotate through the meshing worm wheel 21. When the bidirectional lead screw 2 rotates, the two threaded blocks 22 on its outside move in opposite directions. The threaded blocks 22 drive the guide block 24 to move along the guide groove 23. At the same time, the moving sleeve 26 cooperates with the guide rail 27 to drive the two moving plates 25 to move relative to each other. This causes the pipes fixed in the two mounting frames 3 to move relative to each other, achieving precise docking of the pipe interfaces. The whole process does not require manual alignment of the pipe interfaces, which not only reduces the labor intensity of the operators, but also greatly improves the accuracy and sealing of the pipe docking. In addition, the device can be adapted to pipes of different diameters and has good versatility.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
