Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a positioning device for pipe fitting installation. Background Art

[0002] Pipe fittings are a general term for components that play the role of connection, control, direction change, diversion, sealing, support, etc. in pipeline systems. There are many types of pipe fittings, which can be divided into four categories according to the manufacturing method, namely seamless pipe fittings, seamed pipe fittings, forged pipe fittings, and cast pipe fittings.

[0003] During the installation process of pipe fittings, a positioning device for pipe fitting installation is often used. Pipe fitting installation requires positioning to ensure construction accuracy and installation quality. For example, the construction accuracy requirements for embedded parts are high. To ensure construction accuracy, the steel pipe insertion installation and positioning processes are basically carried out simultaneously. During installation, the two are connected as a whole, and the steel bracket parameters are determined according to the size of the embedded section, and the installation and positioning work is completed on the bracket.

After adjustment, the butt ends of the two pipes can be placed on the two support seats respectively to achieve the positioning effect, thereby improving the scope of use of the positioning device.

The pipes may fall or move during the movement, and the pipes cannot be effectively fixed, thereby reducing the use efficiency of the positioning device. Therefore, we need a positioning device for pipe installation. Utility Model Content

[0029] Through the above technical solution, by placing the pipe fittings in the fixed frame 3 and starting the first motor 401, the two movable plates 403 can be moved in opposite directions, and then the two movable plates 405 can be rotated to drive the lower pressure plate 407 to move up and down, and the lower pressure plate 407 can press the pipe fittings downward to fix them, and then the pipe fittings in the fixed frame 3 can be effectively limited to prevent the position of the pipe fittings from shifting during the docking process, thereby improving the installation and positioning effect of the pipe fittings.

[0030] Specifically, a moving mechanism 5 is disposed inside the workbench 1 , and an anti-sliding block 7 is fixedly connected to the bottom of the base 6 .

[0031] Through the above technical solution, it is convenient to start the moving mechanism 5 to drive the bottom of the telescopic rod 2 to move. The moving mechanism 5 moves the two telescopic rods 2 relative to each other through the screws with opposite threads on both sides, thereby achieving the effect of adjusting the distance between the fixed frame 3, and the anti-sliding block 7 can improve the stability of the positioning device during use to avoid sliding.

[0032] Specifically, the first motor 401 forms a moving structure through the screw rod 402 and the moving plate 403 , and the threads on both sides of the screw rod 402 have opposite rotation directions, and the number of the moving plates 403 is two.

[0033] Through the above technical solution, it is convenient to start the first motor 401 to drive the screw rod 402 to rotate and then drive the movable plate 403 to move. Because the threads on both sides of the screw rod 402 rotate in opposite directions, and the two movable plates 403 are symmetrically arranged on both sides of the screw rod 402, the two movable plates 403 move in opposite directions on both sides of the screw rod 402, thereby achieving the effect of reverse movement of the two movable plates 403.

[0034] Specifically, the moving plate 403 and the movable plate 405 form a rotating structure through the connecting shaft 404 , and the connecting shaft 404 is arranged between the moving plate 403 and the movable plate 405 .

[0035] The above technical solution facilitates the two movable plates 403 to drive the movable plate 405 to rotate through the connecting shaft 404 during the reverse rotation, thereby making the two movable plates 405 rotate in the reverse direction.

[0037] Through the above technical solution, it is convenient to lift the lower pressure plate 407 at the bottom of the connecting block 406 up and down under the mutual restraint of the two movable plates 405, thereby achieving the lifting effect of the lower pressure plate 407. The downward movement of the lower pressure plate 407 can clamp and fix the pipe fittings, thereby achieving the effect of limiting the pipe fittings.

[0038] Specifically, the second motor 801 forms a rotating structure through the first bevel gear 802 and the second bevel gear 803 , and the top of the rotating rod 804 is connected to the bottom of the workbench 1 .

[0039] Through the above technical solution, it is convenient to start the second motor 801 to drive the first bevel gear 802 to rotate while driving the second bevel gear 803 to rotate. The second bevel gear 803 drives the internal rotating rod 804 to rotate synchronously, and then the workbench 1 on the top of the rotating rod 804 rotates, achieving the effect of rotating the workbench 1.

[0040] Specifically, the base 6 forms a sliding structure through the slide groove 805 and the slide rod 806 , and the shape and size of the slide rod 806 match the shape and size of the slide groove 805 , and the top of the slide rod 806 is connected to the bottom of the workbench 1 .

[0041] Through the above technical solution, the workbench 1 can be kept stable by sliding the slide rod 806 in the slide groove 805 during the rotation process, so as to prevent the workbench 1 from tipping over.

[0042] Working principle: when using the positioning device for pipe installation, first, when installing and positioning the pipe, first place the pipe in the fixed frame 3, and then start the first motor 401, the first motor 401 drives the screw rod 402 to rotate, and the screw rod 402 drives the movable plate 403 to move, because the threads on both sides of the screw rod 402 rotate in opposite directions, and the two movable plates 403 are symmetrically arranged on both sides of the screw rod 402, and then the two movable plates 403 move in opposite directions on both sides of the screw rod 402, and then the two movable plates 403 drive the movable plate 405 to rotate in the opposite direction during the reverse rotation through the connecting shaft 404, and then the lower pressure plate 407 at the bottom of the connecting block 406 is lifted up and down under the mutual restraint of the two movable plates 405, so as to achieve the lower pressure. The lifting effect of plate 407 and the downward movement of the lower pressure plate 407 can clamp and fix the pipe fittings. When rotating the positioning device, it is only necessary to start the second motor 801. The second motor 801 drives the first bevel gear 802 to rotate. The first bevel gear 802 drives the second bevel gear 803 to rotate due to the meshing action. The second bevel gear 803 drives the rotating rod 804 to rotate, and then the workbench 1 on the top of the rotating rod 804 is rotated. During the rotation, the workbench 1 is kept stable by sliding in the slide groove 805 through the slide bar 806 to prevent the workbench 1 from tipping over, and then the pipe fittings on the positioning device are rotated. This completes all the work. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
