Technical Field

[0001] This utility model relates to the technical field of spray painting and corrosion protection equipment, and in particular to a spray painting and corrosion protection equipment for ductile iron pipes. Background Technology

[0002] Cast iron pipe is essentially ductile iron pipe. It is called ductile iron pipe because it has the essence of iron and the performance of steel. In ductile iron pipe, the graphite exists in a spherical form. Generally, the size of the graphite is grade 6-7. In terms of quality, the spheroidization grade of cast iron pipe is required to be controlled at grade 1-3, and the spheroidization rate is ≥80%. Therefore, the mechanical properties of the material itself are well improved, and it has the essence of iron and the performance of steel.

[0003] In the production process of ductile iron pipes, a corresponding anti-corrosion coating needs to be sprayed on the outer surface of the pipes to protect them. In existing technologies, a rotating roller process is generally used to drive the pipes during the spraying process. However, the stability and firmness of the ductile iron pipes during rotation using this driving device are poor, leading to problems such as the anti-corrosion coating peeling off or uneven thickness, seriously affecting the product quality of the ductile iron pipes. Therefore, this utility model proposes a surface painting and anti-corrosion device for ductile iron pipes to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a surface painting and anti-corrosion device for ductile iron pipes. This device solves the problem in the prior art where the stability and firmness of ductile iron pipes during rotation are poor, leading to the peeling or uneven thickness of the anti-corrosion coating during the painting process, which seriously affects the product quality of ductile iron pipes.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a surface painting and anti-corrosion device for ductile iron pipes, including an electric roller table, a slide rail, a sliding rod and a sliding frame. The electric roller table is symmetrically provided with slide rails on both sides. The slide rails are slidably connected inside the slide rails. The sliding rods are provided with sliding frames. A painting mechanism is provided on one side of the sliding frame and a guide mechanism is provided on the other side of the sliding frame.

[0006] A further improvement is made in that: the guiding mechanism includes a rotating rod, a roller frame and a threaded rod, the other side of the sliding frame is hinged to the rotating rod, one end of the rotating rod is hinged to the roller frame, the top of the other end of the sliding frame is threaded to the threaded rod, and the bottom end of the threaded rod is fitted and connected to the outer wall of the rotating rod.

[0007] A further improvement is made in that: a fixed plate is fixedly connected to the bottom end of the sliding rod, a guide plate is fixed to one side of the fixed plate, a movable support foot is slidably connected to the inner side of the guide plate, the top end of the movable support foot is fixedly connected to the bottom of the sliding frame, a hydraulic cylinder is fixedly installed on the outer side of the sliding rod, and the output end of the hydraulic cylinder is fixedly connected to one side of the bottom of the sliding frame.

[0008] A further improvement is that: a paint storage tank is provided on the top of the fixed plate, and a feed pipe is connected to the top of the paint storage tank, with an end cap threadedly installed at the top of the feed pipe.

[0009] A further improvement is made in that: the painting mechanism includes a spray head, a paint pump and a hose; the spray head is installed on the top of one side of the sliding frame; the paint pump is installed on the top of the fixed plate; the output end of the paint pump is connected to one end of the spray head through a hose; and the input end of the paint pump is connected to the bottom of the paint storage tank.

[0010] A further improvement is that a lead screw is rotatably connected to the top of the slide rail, a motor is installed on one side of the slide rail, one end of the lead screw is fixedly connected to the output end of the motor, and one end of the lead screw passes through the bottom end of the slide rod and is threadedly connected to it.

[0011] A further improvement is that the roller frame includes a connecting frame and rollers. The connecting frame is V-shaped. One end of the rotating rod is hinged to one side of the connecting frame via a pivot. Rollers are symmetrically hinged to both ends of the connecting frame.

[0012] The beneficial effects of this utility model are as follows: The output end of the hydraulic cylinder is connected to the rotating rod through a sliding frame. The output end of the hydraulic cylinder drives the roller frame on the rotating rod to move closer to the outer wall of the ductile iron pipe, so that the outer wall of the roller frame fits against the ductile iron pipe. Then, the threaded rod is turned downwards, so that the bottom end of the threaded rod presses against the rotating rod. The threaded rod restricts the rotating rod from driving the roller frame to rotate upwards, thereby locking its position.

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a surface painting and anti-corrosion device for ductile iron pipes, including an electric roller table 1, a slide rail 2, a sliding rod 3, and a sliding frame 4. The device is characterized in that: the electric roller table 1 has symmetrically arranged slide rails 2 on both sides; the slide rails 2 are slidably connected to the interior of the slide rails 2; the sliding rods 3 are equipped with sliding frames 4; one side of the sliding frame 4 is equipped with a painting mechanism; and the other side of the sliding frame 4 is equipped with a guiding mechanism. When the ductile iron pipe is placed on the electric roller table 1, the guiding mechanism on the sliding frame 4 can restrict the position of the ductile iron pipe when the electric roller table 1 drives the ductile iron pipe to rotate, making its rotation more stable. Then, the painting mechanism sprays paint onto the outer wall of the ductile iron pipe. Due to the reduced vibration of the ductile iron pipe, the paint coating on the outer wall of the ductile iron pipe is more uniform, resulting in a better anti-corrosion effect.

[0019] The guiding mechanism includes a rotating rod 5, a roller frame 6, and a threaded rod 7. The rotating rod 5 is hinged to the other side of the sliding frame 4. The roller frame 6 is hinged to one end of the rotating rod 5. The threaded rod 7 is threaded to the top of the other end of the sliding frame 4. The bottom end of the threaded rod 7 is in contact with the outer wall of the rotating rod 5.

[0020] A fixed plate 8 is fixedly connected to the bottom end of the sliding rod 3. A guide plate 9 is fixed to one side of the fixed plate 8. A movable support leg 10 is slidably connected to the inner side of the guide plate 9. The top end of the movable support leg 10 is fixedly connected to the bottom of the sliding frame 4. A hydraulic cylinder 11 is fixedly installed on the outer side of the sliding rod 3. The output end of the hydraulic cylinder 11 is fixedly connected to one side of the bottom of the sliding frame 4. The output end of the hydraulic cylinder 11 is connected to the rotating rod 5 through the sliding frame 4. The output end of the hydraulic cylinder 11 drives the roller frame 6 on the rotating rod 5 to move closer to the outer wall of the ductile iron pipe, so that the outer wall of the roller frame 6 fits against the ductile iron pipe. Then, the threaded rod 7 is turned downwards, so that the bottom end of the threaded rod 7 presses against the rotating rod 5. The threaded rod 7 restricts the rotating rod 5 from driving the roller frame 6 to rotate upwards, thereby locking its position. The two sides of the ductile iron pipe are restricted in position by two roller frames 6, which makes the ductile iron pipe more stable when it rotates on the electric roller table 1.

[0021] The top of the fixed plate 8 is provided with a paint storage tank 12, and the top of the paint storage tank 12 is connected to a feed pipe 13. The top end of the feed pipe 13 is threadedly connected to an end cap. The painting mechanism includes a spray head 14, a paint pump 15, and a hose 16. The spray head 14 is installed on the top of one side of the sliding frame 4, and the paint pump 15 is installed on the top of the fixed plate 8. The output end of the paint pump 15 is connected to one end of the spray head 14 through the hose 16, and the input end of the paint pump 15 is connected to the bottom of the paint storage tank 12. The end cap is unscrewed from the top of the feed pipe 13 to fill the paint storage tank 12 with paint, and then the end cap is screwed back onto the top of the feed pipe 13. The paint pump 15 and the hose 16 work together to transport the paint in the feed pipe 13 to the inside of the spray head 14. The spray head 14 then automatically sprays the paint onto the ductile iron pipe. The hose 16 is flexible and will not be affected by the movement of the spray head 14 driven by the sliding frame 4.

[0022] A lead screw 18 is rotatably connected to the top of the slide rail 2. A motor 17 is installed on one side of the slide rail 2. One end of the lead screw 18 is fixedly connected to the output end of the motor 17. One end of the lead screw 18 passes through the bottom end of the sliding rod 3 and is threadedly connected to it. The output end of the motor 17 drives the lead screw 18 to rotate on the top of the slide rail 2. The lead screw 18 is threadedly engaged with the bottom end of the sliding rod 3, and the slide rail 2 restricts the movement trajectory of the sliding rod 3. Thus, while the lead screw 18 rotates in both directions, it drives the sliding rod 3 to move linearly back and forth on the slide rail 2. The spray head 14 is connected to the fixed plate 8 through the sliding frame 4, the guide plate 9, and the movable support 10. The fixed plate 8 is also connected to the bottom end of the sliding rod 3, so it can drive the spray head 14 to move linearly back and forth. This works in conjunction with the electric roller table 1 driving the ductile iron pipe to rotate, spraying paint onto the entire surface of the ductile iron pipe.

[0023] The roller frame 6 includes a connecting frame and rollers. The connecting frame is V-shaped. One end of the rotating rod 5 is hinged to one side of the connecting frame via a pivot. Rollers are symmetrically hinged to both ends of the connecting frame.

[0024] The surface painting and anti-corrosion equipment for ductile iron pipes uses a hydraulic cylinder 11 whose output end is connected to a rotating rod 5 via a sliding frame 4. The output end of the hydraulic cylinder 11 drives the roller frame 6 on the rotating rod 5 to move closer to the outer wall of the ductile iron pipe, so that the outer wall of the roller frame 6 fits against the ductile iron pipe. Then, the threaded rod 7 is turned downwards, so that the bottom end of the threaded rod 7 presses against the rotating rod 5. The threaded rod 7 restricts the rotating rod 5 from driving the roller frame 6 to rotate upwards, thereby locking its position. The two sides of the ductile iron pipe are restricted in position by two roller frames 6, which makes the ductile iron pipe more stable when rotating on the electric roller table 1, and the paint spraying on the outer wall of the ductile iron pipe is more uniform, resulting in better anti-corrosion effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
