[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figs. 1 to 4 The illustrated positioning device for a pipeline in a water conservancy project includes a mounting top plate 1 and an adjusting device. The mounting top plate 1 has two parallel mounting slots 12. Each of the two mounting slots 12 contains an identical adjusting device. The adjusting device includes a positioning assembly, a threaded rod 2, and a connecting block 3. The positioning assembly includes a rotating gear 6 and two serrated plates 7 that mesh with the rotating gear 6. The two serrated plates 7 are centrally symmetrical about the rotating gear 6. The rotating gear 6 is positioned in the middle of the mounting slots 12. The bottom of the mounting slots 12 on both sides of the rotating gear 6... The unit is provided with a sliding channel 121; two adjusting blocks 71 are respectively provided at the outer ends of the two serrated plates 7; the adjusting blocks 71 and the serrated plates 7 are slidably disposed in the mounting groove 12; threaded rods 2 are rotatably connected in both adjusting blocks 71; the threaded rods 2 are vertically disposed downward from the sliding channel 121; the two threaded rods 2 in the same mounting groove 12 are symmetrical to each other; the width of the sliding channel 121 is the same as the diameter of the threaded rods 2, ensuring that the threaded rods 2 can slide in the sliding channel 121, while the adjusting blocks 7 and the serrated plates 71 slide in the mounting groove 12.
[0020] The threaded rod 2 is rotatably fitted with a connecting block 3; the threaded rod 2 is provided with a graduated cylinder 4 on its outside; the graduated cylinder 4 is provided with a notch 43 in the vertical direction; the connecting block 3 extends out from the notch 43, and the graduated cylinder notches 43 on both sides are arranged opposite to each other. The connecting block 4 is located between the graduated cylinder 4 and the threaded rod 2, and moves up and down as the threaded rod 2 rotates. The outer surface of the graduated cylinder 4 is engraved with scale lines 42, which are used to determine the position of each connecting block 3, ensuring that the connecting blocks 3 are at the same height, and ensuring the concentricity of two pipes with different diameters.
[0021] The adjusting block 71 is provided with a through hole 711; the position of the through hole 711 corresponds to the position of the sawtooth plate 7 on the opposite surface, and the sawtooth plate 7 can pass through the through hole 711 on the opposite side, increasing the travel trajectory of the sawtooth plate 7.
[0022] The extended end of the connecting block 3 is provided with an arc-shaped clamp 5, and the connecting block 3 is located on the center line of the arc-shaped clamp 5; the pipe can be fixed from both sides.
[0023] The bottom of the graduated cylinder 4 is fixed on the base plate 41; the threaded rod 2 is rotatably connected to the base plate 41, and a common rotatable connection method such as a tray can be used; the base plate 41 is a thin metal plate, which can be a steel plate or an iron plate. When clamping movement occurs, the base plate 41 may sometimes insert into the bottom of the pipe. If the base plate is too thick, it may affect the installation of the pipe. Therefore, a thin metal plate with a certain rigidity that will not deform is selected.
[0024] The rotating gear 6 has a rotating shaft in the middle; the rotating shaft is fixedly installed at the motor output end 61. The rotation of the rotating shaft is controlled by the motor 61, which adjusts the relative movement of the sawtooth plate 7, causing the two side adjusting blocks 71 to slide, and linking the threaded rods 2 and the arc-shaped clamping plates 5 on both sides to move towards the middle, clamping the middle pipe section. The two motors 61 can operate independently and can separately control the clamping distance between the two positioning components, which is suitable for fixing pipes of different diameters.
[0025] The top of the threaded rod 2 extends to the outside of the mounting groove 12; the top of the threaded rod 2 is provided with a rotating handle 21. By manually controlling the rotating handle 21, the threaded rod 2 will rotate. At this time, the connecting block 3 will slide up and down along the threaded rod 2. By observing the scale of the external scale cylinder 4, the four connecting blocks 3 can be adjusted to the same height position, thereby controlling the center of the two pipe sections to be on the same straight line, avoiding repeated position adjustments, and facilitating subsequent installation.
[0026] Normally, the mounting slot 12 is located inside the mounting top plate 1, and the top of the mounting slot 12 is sealed. At this time, the motor 61 and the rotating handle 21 are both installed on the top surface of the mounting top plate 1 for easy adjustment.
[0027] When the device is in operation, first adjust the positioning component to move the threaded rod 2 as far to the sides as possible. Place the device into the pipe section interface from above the pipe. The two mounting slots 12 are respectively located above the two pipe sections to be connected. Then adjust the rotating handle 21 to adjust the four connecting blocks 4 to the same position on the graduated cylinder according to the pipe diameter. At this time, the arc-shaped clamps 5 are located on both sides of the pipe. Start the motor 61. The arc-shaped clamps 5 on both sides will converge towards the middle. If the pipe section diameter is small, the position of the pipe section can be slightly adjusted by external force during the clamping process so that the center of the pipe section is located on the center line of the arc-shaped clamp 5 to clamp the pipe. Control the clamping force not to be too tight. Finally, manually adjust and push the pipe section to connect the two pipes.
[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
