Description

Technical Field

[0001] This utility model belongs to the field of pipeline connection technology, specifically referring to an HDPE water supply pipe connection device. Background Technology

[0002] HDPE water supply pipes are a replacement for traditional steel pipes and polyvinyl chloride drinking water pipes. They have advantages such as stable and reliable joints, impact resistance, crack resistance, aging resistance, and corrosion resistance. During installation, multiple sets of HDPE water pipes usually need to be connected on site.

[0003] Existing connection devices, such as the HDPE water supply pipe connection device disclosed in application number CN202322077363.2, use an electric push rod to lift the lifting plate, thus eliminating the need for manual handling of the heat fusion device. This facilitates better connection of the two water pipes after heat fusion, prevents interference with the connection during handling, and makes the connection of the two water pipes more automated, thereby improving safety.

[0004] However, in practical use, existing connection devices, when fixing HDPE pipes of different diameters, have fixed clamping blocks of a fixed size that cannot accommodate water pipes of different sizes. This necessitates the replacement of different clamping blocks, making the replacement operation complex and inefficient. Furthermore, since HDPE pipes are relatively soft, their ends are easily damaged during storage and transportation, resulting in low precision and strength during connection. Existing methods use external angle grinders for correction, which is complex and makes it difficult to guarantee the flatness of the ends of the two sets of water pipes to be connected. Therefore, we propose an HDPE water supply pipe connection device to solve the above problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides an HDPE water supply pipe connection device, which effectively solves the problems of complicated operation and low efficiency when fixing HDPE pipes of different sizes in the existing HDPE water supply pipe connection device, and solves the problem that it is difficult to ensure the flatness of the end of the water pipe to be connected, thus affecting the connection stability.

[0006] The technical solution adopted by this utility model is as follows: This utility model proposes an HDPE water supply pipe connection device, including a base plate, a support frame and a guide rod. The support frame is fixedly installed at both ends of the top of the base plate. The guide rod is fixed on the support frame and is arranged parallel to the base plate. The guide rod is provided with a diameter changing and fixing mechanism. A locking block is inserted and pulled on the guide rod, and the locking block and the guide rod are slidably connected. A retaining ring is fixed on the locking block, and a grinding and heating mechanism is provided on the retaining ring.

[0007] As an improvement to this solution, a movable slider one is slidably connected to the guide rod, and a fixing screw is threadedly connected to one side wall of the movable slider, and the fixing screw passes through the movable slider one and is abutted against the guide rod. A movable slider two is slidably connected to one side of the guide rod symmetrical to the movable slider one.

[0008] As an improvement to this solution, the variable diameter fixing mechanism includes a lower fixing ring, an upper fixing ring, and a washer ring. The lower fixing ring is fixed to both sides of the upper end of the movable slider. The upper fixing ring is rotatably connected to the lower fixing ring. The washer ring is plugged into and detached from the lower fixing ring and the upper fixing ring, and is slidably connected to the lower fixing ring and the upper fixing ring.

[0009] As an improvement to this solution, a drive screw is rotatably connected to the support frame, and the drive screw is arranged parallel to the guide rod. The bottom of the lower fixing ring on the second movable slider is fixed with a drive slider, and the drive slider is threadedly connected to the drive screw.

[0010] As an improvement to this solution, the grinding heating mechanism includes a heating plate, a grinding shell, a grinding disc, and a grinding motor. The heating plate is rotatably connected to one side of the retaining ring, the grinding shell is rotatably connected to the retaining ring and is symmetrically distributed with the heating plate, the grinding disc is rotatably connected inside the grinding shell, and the grinding motor is located on the grinding shell.

[0011] As an improvement to this solution, a drive wheel is rotatably connected inside the grinding housing, and the drive wheel is connected to the output shaft of the grinding motor. A driven wheel is fixed on the grinding disc, and the driven wheel is connected to the belt via the belt.

[0012] As an improvement to this solution, the retaining ring is located between the drive screw and the guide rod, the retaining ring is coaxial with the lower fixed ring, and the heating plate is arranged on the same plane as the grinding disc.

[0013] As an improvement to this solution, the lower fixing ring, the upper fixing ring, and the retaining ring are all set as semi-circular rings with a U-shaped cross-section, and the pad ring is set as a semi-circular ring with a U-shaped cross-section and a T-shaped protrusion is fixed on its outer wall.

[0014] The beneficial effects of this utility model by adopting the above structure are as follows:

[0015] 1. The variable diameter fixing mechanism is adopted. Different sized washers can be quickly inserted into the lower and upper fixing rings, thereby satisfying the clamping and fixing of HDPE pipes of different sizes, improving the applicability range, and the structure is simple, reliable, easy to operate, and improving the efficiency of use.

[0016] 2. It is equipped with a detachable grinding and heating mechanism.

The guide rod 3 is provided with a diameter changing fixing mechanism 4. A locking block 5 is inserted and pulled onto the guide rod 3, and the locking block 5 is slidably connected to the guide rod 3. A retaining ring 6 is fixed on the locking block 5, and a grinding and heating mechanism 7 is provided on the retaining ring 6. A movable slider 1 8 is slidably connected to the guide rod 3. A fixing screw 9 is threadedly connected to the side wall of the movable slider 1 8, and the fixing screw 9 passes through the movable slider 1 8 and is abutted against the guide rod 3. A movable slider 2 10 is slidably connected to the guide rod 3 on the side symmetrical to the movable slider 1 8.

[0025] To clamp and fix HDPE water supply pipes of different diameters, the variable diameter fixing mechanism 4 includes a lower fixing ring 11, an upper fixing ring 12, and a washer 13. The lower fixing ring 11 is fixed to both sides of the upper end of the movable slider 8. The upper fixing ring 12 is rotatably connected to the lower fixing ring 11. The washer 13 is plugged into and slidably connected to the lower fixing ring 11 and the upper fixing ring 12. A drive screw 14 is rotatably connected to the support frame 2, and the drive screw 14 is parallel to the guide rod 3. The bottom of the lower fixing ring 11 on the movable slider 10 is fixed with a drive slider 15, and the drive slider 15 is threadedly connected to the drive screw 14.

[0026] To ensure the certification of HDPE water supply pipe connection ports and improve connection stability, the grinding and heating mechanism 7 includes a heating plate 16, a grinding shell 17, a grinding disc 18, and a grinding motor 19. The heating plate 16 is rotatably connected to one side of the retaining ring 6. The grinding shell 17 is rotatably connected to the retaining ring 6 and is symmetrically distributed with the heating plate 16. The grinding disc 18 is rotatably connected inside the grinding shell 17. The grinding motor 19 is located on the grinding shell 17. A drive wheel 20 is rotatably connected inside the grinding shell 17 and is connected to the output shaft of the grinding motor 19. A driven wheel 21 is fixed on the grinding disc 18 and is connected to the belt 22 via the belt 22.
