Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage pipeline installation technology, and in particular to a precision positioning device for water supply and drainage pipeline installation. Background Technology

[0002] Water supply and drainage is a general term for "water supply" and "drainage". It is responsible for the entire process of water supply, distribution, use and waste disposal. Water supply and drainage pipelines are physical channels connecting water sources, users and treatment facilities. When installing water supply and drainage pipelines, it is usually necessary to locate the pipelines.

[0003] A search revealed that Chinese patent CN223147808U discloses a positioning device for water supply and drainage pipe installation. In actual operation, the pipes being connected are often long and heavy. If manual connection is used, it is extremely easy for the connection to shift, making it impossible to accurately insert the other pipe into the joint, and the heat fusion end is easily damaged. This can result in minor damage to the appearance or, in severe cases, an unsealed connection leading to subsequent leakage. Therefore, this device is easy to operate, can effectively position and guide the pipe, and improve the efficiency and accuracy of pipe connection.

[0004] The aforementioned positioning device is only convenient for positioning and installing two straight pipes, but not for connecting bends and straight pipes. When connecting water supply and drainage pipes, right-angle bends are usually connected to straight pipes. However, in the existing technology, when connecting right-angle bends to straight pipes, operators need to hold the bend and straight pipes separately and carefully align the pipe openings. After positioning and aligning, the pipes are sealed and fixed. The positioning and alignment process requires considerable care. If there is hand tremor or accidental contact, the positioned and aligned pipes are prone to displacement, which makes it difficult to seal the pipes and reduces the efficiency of pipe connection. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a precise positioning device for water supply and drainage pipe installation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a precision positioning device for water supply and drainage pipeline installation, including an L-shaped connecting frame, wherein a positioning component is provided on one side of the L-shaped connecting frame;

[0007] The positioning component includes a first connecting frame, which is fixedly connected to one side of the straight edge of the L-shaped connecting frame. A second connecting frame is fixedly connected to the lower surface of the first connecting frame. A handle is fixedly connected to one side of the second connecting frame. A stepper motor is provided on one side of the other straight edge of the L-shaped connecting frame. A screw is fixedly connected to the output end of the stepper motor. A movable frame is threadedly connected to the external thread of the screw.

[0008] As a further description of the above technical solution:

[0009] One end of the movable frame is fixedly connected to a corner clamp, and one side of the L-shaped connecting frame is fixedly connected to a corner clamp. The movable frame is slidably connected to the outside of the L-shaped connecting frame, and the stepper motor is fixedly installed on one side of the movable frame.

[0010] As a further description of the above technical solution:

[0011] Both the first and second corner clamps have weight-reducing grooves inside, and stepper motors are fixedly installed inside the first and second connecting frames.

[0012] As a further description of the above technical solution:

[0013] The output end of the stepper motor is fixedly connected to a lead screw. Heat dissipation grooves are provided on both sides of the first connecting frame and the second connecting frame. Push-pull columns are slidably connected inside the first connecting frame and the second connecting frame.

[0014] As a further description of the above technical solution:

[0015] The push-pull column has a threaded groove inside, and the lead screw is threaded into the inside of the threaded groove.

[0016] As a further description of the above technical solution:

[0017] One end of the push-pull column is fixedly connected to a straight tube frame, the middle of the straight tube frame is fixedly connected to a mounting bracket, a stepper motor is fixedly installed on one side of the mounting bracket, and a screw is fixedly connected to the output end of the stepper motor.

[0018] As a further description of the above technical solution:

[0019] The screw two is externally threaded to a movable frame two, which is slidably connected to the outside of the mounting frame. One end of the movable frame two is fixedly connected to a straight pipe frame two.

[0020] This utility model has the following beneficial effects:

[0021] This utility model, through the setting of positioning components, utilizes corner clamp shell one and corner clamp shell two to facilitate the pre-fixation of right-angle bends. Under the action of straight pipe bracket one and straight pipe bracket two on both sides, it is easy to clamp and pre-fix the straight pipes connected to the right-angle bends on both sides. At this time, the right-angle bends and straight pipes will be on the same center line, which facilitates the pre-positioning of the pipes. Under the sliding action of the push-pull columns on both sides inside the first connecting frame, it is easy to pull the straight pipes connected to the right-angle bends on both sides closer to the right-angle bends and press them together. When pressed together, it helps to seal and accurately position the connection between the right-angle bends and straight pipes, thereby facilitating the sealed connection and fixation of the pipes.

[0030] 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.

[0031] As attached Figure 1-6 As shown, one embodiment of the present invention provides a precision positioning device for water supply and drainage pipe installation, including an L-shaped connecting frame 1, with a positioning component provided on one side of the L-shaped connecting frame 1;

[0032] The positioning assembly includes a first connecting frame 2, which is fixedly connected to one side of the straight edge of the L-shaped connecting frame 1. A second connecting frame 3 is fixedly connected to the lower surface of the first connecting frame 2, and a handle 4 is fixedly connected to one side of the second connecting frame 3 for easy gripping. A stepper motor 5 is provided on the other straight edge of the L-shaped connecting frame 1. A screw 6 is fixedly connected to the output end of the stepper motor 5. A movable frame 7 is threadedly connected to the outside of the screw 6 and slidably connected to the outside of the L-shaped connecting frame 1. The stepper motor 5 is fixedly installed on one side of the movable frame 7. A support base is fixedly provided on the L-shaped connecting frame 1 on the same side as the screw 6. The other end of the screw 6 is rotatably connected to the support base. The rotation of the stepper motor 5 drives the rotation of the screw 6, allowing the movable frame 7 to move on the L-shaped connecting frame 1.

[0033] As attached Figure 1 As shown, one end of the movable frame 7 is fixedly connected to a corner clamp 8, and one side of the L-shaped connecting frame 1 is fixedly connected to a corner clamp 9, which facilitates clamping the bent pipe. Both the corner clamp 8 and the corner clamp 9 have weight-reducing grooves 10 inside to reduce their weight.

[0034] As attached Figure 3 As shown, stepper motors 11 are fixedly installed inside the first connecting frame 2 and the second connecting frame 3. The output end of the stepper motor 11 is fixedly connected to a lead screw 12, which drives the lead screw 12 to rotate. Heat dissipation slots 13 are provided on both sides of the first connecting frame 2 and the second connecting frame 3 to facilitate heat dissipation of the internal stepper motors 11.

[0035] As attached Figure 5 As shown, push-pull columns 14 are slidably connected inside the first connecting frame 2 and the second connecting frame 3, indirectly pulling the fixed straight pipe closer to the curved pipe. The push-pull column 14 has a threaded groove 15 inside, which matches the thread of the lead screw 12. The lead screw 12 is threaded inside the threaded groove 15, which facilitates the lead screw 12 to drive the push-pull column 14 to move through the threaded groove 15. One end of the push-pull column 14 is fixedly connected to a straight pipe bracket 16, which facilitates limiting one side of the straight pipe. A mounting bracket 17 is fixedly connected to the middle of the straight pipe bracket 16. A stepper motor 18 is fixedly mounted on one side of the mounting bracket 17. A screw 19 is fixedly connected to the output end of the stepper motor 18. A support seat is fixedly set on the mounting bracket 17 on the same side as the screw 19. The other end of the screw 19 is rotatably connected to the support seat.

[0036] As attached Figure 6 As shown, the external thread of the screw 19 is connected to the movable frame 20. The movable frame 20 is slidably connected to the outside of the mounting frame 17. The mounting frame 17 limits the movable frame 20. One end of the movable frame 20 is fixedly connected to the straight pipe frame 21, which facilitates limiting the other side of the straight pipe.

[0037] Working principle: During use, the operator first holds handle 4 to keep the entire unit upright. Then, the middle of the right-angle bend is positioned at corner clamp 29. An external controller is used to start stepper motor 5. The output of stepper motor 5 drives screw 6 to rotate, which in turn causes the moving frame 7 to slide outside the L-shaped connecting frame 1. This causes corner clamp 8 to move closer to corner clamp 29. Corner clamps 8 and 29 then clamp the right-angle bend, fixing it in place. Next, the straight pipes on both sides are positioned at straight pipe supports 16 on both sides. Stepper motor 218 is then started, causing its output to drive screw 219 to rotate, which in turn drives the moving frame 22... The tube 0 slides outside the mounting bracket 17, which in turn drives the straight tube bracket 21 to approach the straight tube bracket 16. The straight tube is clamped and fixed by the straight tube bracket 16 and the straight tube bracket 21. At this time, the straight tube and the bend are on the same horizontal line. Then, the stepper motor 11 is started, and its output end drives the lead screw 12 to rotate, which in turn drives the two push-pull columns 14 to move towards one side of the stepper motor 11 inside the first connecting frame 2 and the second connecting frame 3, respectively. At this time, the push-pull columns 14 will drive the two clamped and fixed straight tubes to approach and press against the two ends of the bend, which facilitates the positioning of the straight tube and the bend. At this time, the sealing connection components of the straight tube and the bend can be installed conveniently.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
