Description

Technical Field

[0001] The invention relates to the technical field of pipeline installation, in particular to a method for installing a water conservancy project pipeline. Background Art

[0002] A water conservancy project is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. It is also called a water project.

[0003] In water conservancy projects, for the convenience of use, it is often necessary to install and connect two water conservancy pipes. During installation, the two pipes are connected by flanges. After the flanges on the two pipes are tightened by bolts, the two pipes are fixedly installed.

[0004] For example, an auxiliary pipe joint positioning mechanism for water conservancy projects with publication number CN214618153U can increase the stability of the fixation of the pipe joint, making it convenient for people to control the position of the pipe joint for docking, and can also facilitate people to disassemble and store the entire device, making it convenient for people to carry it, bringing better usage prospects.

[0005] However, during the installation of water conservancy pipelines, the flanges at both ends of the pipelines are first welded in advance, and then the pipelines are hoisted on the support frame through the auxiliary pipeline joint positioning mechanism similar to the above-mentioned, and then the two adjacent flanges are connected. This results in the pipelines having to be manually rotated to align the bolt holes between the two adjacent flanges during flange connection, and it is not convenient to flip the pipelines at high places, which not only poses a safety hazard, but also affects the efficiency of pipeline installation.

[0006] In order to improve the sealing performance of the two pipes after connection, the dust and impurities attached to the connection surfaces of the two pipes need to be manually cleaned before the water pipes are installed to ensure that the pipe connection surfaces can fit tightly. However, the manual cleaning process of the water pipe connection ends is inconvenient, which increases the labor intensity of the workers and reduces the efficiency of the pipe installation. Summary of the invention

[0007] The purpose of the present invention is to provide a method for installing a water conservancy project pipeline, which solves the problems raised in the above-mentioned background technology.

Under the action of the friction force of the rubber cushion layer, the pipeline can be fixed before installation;

Therefore, after the installation surface of the pipe is cleaned, the two pipes can continue to move to a position where they fit together for subsequent installation, thereby improving the efficiency of pipe installation in water conservancy projects.

[0033] 3. After the driving motor is turned on, as the threaded rod 1 continues to rotate, when the installation surfaces of the two pipes are fitted together, the meshing action of gear 1, gear 2 and the teeth will cause the connecting ring on the right to drive the pipe on the right to rotate, thereby mechanically aligning the bolt holes on the two flanges. Compared with the traditional manual alignment method of turning over the pipe, this avoids the safety hazards caused by manual turning over, and also further improves the efficiency of pipe installation in water conservancy projects.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] For examples, see Figures 1 to 7 The present invention provides a method for installing a water conservancy project pipeline as follows:

[0044] Put the two pipes 5 to be installed and connected into the openings on both sides of the two fixing platforms 2 respectively, turn the handle to drive the second threaded rod 42 to rotate, so that the first rotating plate 39 deflects in the direction close to the center of the fixing ring 41 until the three abutting blocks abut against the outer wall of the pipe 5. Under the action of the friction force of the rubber cushion layer, the pipe 5 can be fixed before installation;

[0045] When the two pipes 5 are fixed, the driving motor 14 is turned on to drive the two threaded rods 12 and the rotating shaft 20 to rotate synchronously, so that the two pipes 5 can move toward each other.

[0046] At the same time, the piston cylinder 16 will perform piston movement, and the cleaning ring 7 will start to spray air toward the connection surface of the two pipes 5, so as to clean the dust and impurities on the connection surface of the two pipes 5;

[0047] As the two pipes 5 continue to move toward each other, when the abutment block 30 abuts against the slider 32, the piston cylinder 16 and the cleaning ring 7 move away from the two pipes 5 under the hinged action of the hinged plate 37, so as to no longer block the moving path of the pipes 5;

[0048] As the threaded rod 12 continues to rotate, the two fixing platforms 2 will drive the two pipes 5 to move to a position where they fit together, and under the meshing action of gear 1 33, gear 2 36 and teeth 29, the connecting ring 28 on the right will drive the fixed pipe 5 to rotate synchronously until the bolt holes on the two flanges 6 are aligned, and the installation of the two pipes 5 can be completed by fixing the bolts.

[0049] Furthermore, a flange 6 is provided on the surface of the pipe 5, a fixing plate is fixedly connected between the two installation frames 1, a driving motor 14 is provided on the upper surface of the fixing plate, an output shaft of the driving motor 14 is fixedly connected to a rotating shaft 13, a threaded rod 12 is rotatably connected to the surfaces of the two installation frames 1, and a pulley transmission mechanism is provided between the two threaded rods 12 and the rotating shaft 13;

[0050] The surface of the threaded rod 12 is provided with two oppositely arranged thread grooves, the surface of the threaded rod 12 is threadedly connected with two symmetrically arranged moving blocks 27, and the upper surface of the moving block 27 is fixedly connected with the fixing platform 2;

[0051] The fixing component is arranged on the fixing platform 2, and the fixing component includes a connecting ring 28 which is rotatably connected to the surface of the fixing platform 2 via a fixed axis, a fixing ring 41 is rotatably connected to the surface of the connecting ring 28 via a fixed axis, a rotating plate 39 is hingedly connected to the surface of the connecting ring 28, and a limiting block 40 is slidably connected to the outer surface of the rotating plate 39, a hinged rod is hingedly connected to the surface of the fixing ring 41, and the fixing ring 41 is hingedly connected to the limiting block 40 via the hinged rod, an arc-shaped opening 38 for sliding of the limiting block 40 is provided on the surface of the fixing ring 41, and an abutting block is fixedly connected to the side of the rotating plate 39, and a rubber cushion layer is provided on the surface of the abutting block;

[0052] The surface of the connecting ring 28 is fixedly connected to a connecting block 1 45, the upper surface of the connecting block 1 45 is fixedly connected to a connecting block 2, the surface of the connecting ring 28 is rotatably connected to a fixing block 43, the surface of the fixing block 43 is rotatably connected to a threaded rod 2 42, one end of the threaded rod 2 42 is fixedly connected to a turning handle, and the other end of the threaded rod 2 42 passes through the connecting block 2 and is threadedly connected thereto.

[0053] A support frame 15 is fixedly connected to the upper surface of the installation frame 1 , a support block 11 is disposed at the end of the support frame 15 , and a positioning block 44 is fixedly connected to the surface of the installation frame 1 .

[0054] When this embodiment is used, Figure 2 As shown, the two pipes 5 to be installed and connected are respectively placed from the openings on both sides of the two fixing platforms 2 until the flange 6 at the end of the pipe 5 is flush with the positioning block 44 on one side thereof, and then the turning handle at the end of the threaded rod 42 is turned to drive the threaded rod 42 to start rotating.

[0055] like Figure 6 As shown, as the threaded rod 2 42 is driven to rotate, the connecting block 2 will move away from the fixing block 43 , so that the fixing ring 41 can rotate relative to the connecting ring 28 .

[0056] As the connecting ring 28 rotates, under the hinged action of the hinged rod, the limiting block 40 will be relatively deflected with the fixing ring 41 in the arc-shaped opening 38 .

[0057] During the above process, with the rotation of the fixing ring 41 and the deflection of the limit block 40, the rotating plate 39 will deflect along the axis of the hinge rod toward the center of the fixing ring 41 until the abutment blocks on the sides of the three rotating plates 39 abut against the outer wall of the pipe 5. Since a rubber pad is provided on the outer surface of the abutment block, the pipe 5 can be fixed under the action of the friction force of the rubber pad, thereby avoiding shaking of the pipe 5 during the subsequent splicing and installation process, and providing convenience for the subsequent installation of the pipe 5.

[0058] Embodiment 2, based on the above embodiment,

[0059] Further, the cleaning component is arranged in the middle position of the two fixed tables 2, the avoidance component is arranged in the installation frame 1, the calibration component is also arranged in the installation frame 1, the cleaning component includes a limit frame 25 fixedly installed between the two installation frames 1, the surfaces of the two limit frames 25 are slidably connected with the moving blocks 24, the ends of the two moving blocks 24 are commonly fixedly installed with the piston cylinder 16, the inner wall of the piston cylinder 16 is slidably connected with the piston plate, the surface of the piston plate is fixedly connected with the piston rod 17, and the end of the piston rod 17 is fixedly connected with the moving frame 23;

[0060] The lower surface of the piston cylinder 16 is fixedly connected to a support plate 1 22, the surface of the support plate 1 22 is fixedly connected to a rotating shaft 20, the surface of the rotating shaft 20 is fixedly connected to a bevel gear 1 21, and the surface of the threaded rod 12 is fixedly connected to a bevel gear 26 meshing with the bevel gear 1 21;

[0061] The upper surface of the second rotating shaft 20 is fixedly connected with the second rotating plate 19 , and the surface of the second rotating plate 19 is fixedly connected with the moving column 18 . The moving column 18 extends into the moving frame 23 and is slidably connected thereto.

[0062] The surface of the piston cylinder 16 is fixedly connected with an air inlet pipe and an air outlet pipe 9, and two one-way valves are respectively arranged on the surface of the air inlet pipe and the air outlet pipe 9. The end of the air outlet pipe 9 is fixedly connected with a cleaning ring 7, and a plurality of air outlets 8 are evenly arranged on the surface of the cleaning ring 7.

[0063] The avoidance component includes a slide groove 31 provided on the surface of the installation frame 1, a slider 32 is slidably connected to the inner wall of the slide groove 31, a stop block 30 is fixedly connected to the surface of the moving block 27, and a return spring 34 is provided between the slider 32 and the inner wall of the slide groove 31;

[0064] The end of the slide block 32 extending out of the slide slot 31 is hinged with a hinge plate 37 , and the end of the hinge plate 37 is hinged to the second moving block 24 .

[0065] The calibration component includes a gear 1 33 fixedly connected to the surface of the threaded rod 12, a support plate 2 35 fixedly connected to the upper surface of the mounting frame 1, a mounting ring is provided on the surface of the support plate 2 35, and the support plate 2 35 is connected to a gear 2 36 meshing with the gear 1 33 by rotating on a fixed axis through the mounting ring;

[0066] The outer surface of the connecting ring 28 is fixedly connected with teeth 29 that mesh with the second gear 36 .

[0067] When this embodiment is used, Figure 1 to Figure 5 As shown, after the two pipes 5 are fixed on the fixed platform 2, the driving motor 14 is turned on, and under the action of the pulley transmission mechanism, the two threaded rods 12 are driven to start rotating. Since the surface of the threaded rod 12 is provided with two oppositely arranged threaded grooves, the rotation of the threaded rod 12 will drive the two moving blocks 27 to move towards each other, thereby causing the two fixed platforms 2 to move towards each other, so that the two pipes 5 can move towards each other.

[0068] like Figure 5 As shown, as the moving block 27 moves, the stop block 30 will also slide in the slide groove 31 until the stop block 30 slides to a position where it abuts against the sliding block 32.

[0069] In the above process, as the threaded rod 12 rotates, the bevel gear 1 21 and the bevel gear 2 26 mesh with each other, and the rotating shaft 20 will rotate synchronously. Figure 3 As shown, with the rotation of the rotating shaft 20, the rotating plate 219 will rotate, so that the moving column 18 can perform a circular motion around the axis of the rotating shaft 21. Since the moving frame 23 slidably connected to the outer surface of the moving column 18 is limited by the piston rod, the circular motion of the moving column 18 will drive the moving frame 23 to move back and forth, so that the piston rod 17 can drive the piston plate to perform a piston motion in the piston cylinder 16, so that the outside air can be sucked in through the air inlet pipe and evenly sprayed out from the multiple air outlets 8 opened on both sides of the surface of the cleaning ring 7, so that the side of the two pipes 5 that are moving towards each other and are welded with the flange 6 can be cleaned, so that the dust and impurities on the connection surface of the two pipes 5 can be cleaned before the two pipes 5 are spliced ​​and installed, thereby ensuring that the connection surface of the pipe 5 can be tightly fitted during the subsequent splicing and installation, thereby improving the sealing performance of the pipe 5 after the splicing and installation is completed, extending its service life in water conservancy projects, and also reducing maintenance costs.

[0070] When the stopper 30 slides in the chute 31 to the position where it contacts the slider 32, the dust and impurities on the mounting surfaces of the two pipes 5 can be cleaned. Figure 5 and Figure 7As shown, the slider 32 will be pushed to move synchronously, and the reset spring 34 will also be compressed. As the slider 32 moves, under the hinged action of the hinged plate 37, the moving block 24 will move away from the bevel gear 26, so that the piston cylinder 16 and the cleaning ring 7 above will move away from the bevel gear 26, and the bevel gear 1 21 will be disengaged from the bevel gear 26.

[0071] That is, as the two pipes 5 continue to move toward each other, Figure 2 As shown, the cleaning ring 7 will move away from the bevel gear 26 and no longer block the moving path of the pipe 5. At this time, as the threaded rod 12 continues to rotate, the two fixed platforms 2 will drive the two pipes 5 to move to a position where they fit together, and as shown in FIG. Figure 4 and Figure 5 As shown, at this time, the two moving blocks 1 27 will also move to the position closest to each other and will be fully engaged with the thread groove on the surface of the threaded rod 12. At the same time, the teeth 29 on the connecting ring 28 will also move to the position engaged with the gear 2 36.

[0072] Then, as the threaded rod 12 continues to rotate, since the moving block 27 is meshed with the thread groove on the surface of the threaded rod 12, the rotation of the threaded rod 12 will not drive the moving block 27 to move, and under the meshing action of the gear 1 33, the gear 2 36 and the tooth 29, the connecting ring 28 on the right side will start to rotate, so that the pipe 5 fixed on the connecting ring 28 can be rotated until the bolt holes on the two flanges 6 are aligned, and then the driving motor 14 is turned off. At this time, the splicing and installation of the two pipes 5 can be completed by fixing the bolts, and the flanges 6 on the surfaces of the two pipes 5 can be aligned without manually turning over the pipes 5, thereby avoiding the safety hazards caused by manual turning over, and also improving the efficiency of the installation of water conservancy project pipes.

[0073] After the two pipes 5 are spliced ​​and installed, the handle is first rotated in the opposite direction to drive the threaded rod 2 42 to rotate in the opposite direction, so that the three rotating plates 1 39 can be deflected in the opposite direction to enable the abutment block to be separated from the pipe 5. At this time, the two spliced ​​pipes 5 can be moved out from either side of the two fixed platforms 2.

[0074] After the pipe 5 is moved out, the driving motor 14 is turned on to rotate in the opposite direction, so that the threaded groove on the surface of the threaded rod 12 can be meshed with the moving block 27 again. At this time, the moving block 27 and the fixed platform 2 can be reset. At the same time, the stop block 30 will also be reset synchronously with the moving block 27. Under the action of the elastic potential energy of the reset spring 34, the moving block 24 and the piston cylinder 16 can be reset to complete the reset of the device.

[0075] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
