Description

Technical Field

[0001] The utility model relates to the technical field of iron pipe spraying, in particular to a spraying device for producing ductile iron pipes. Background Art

[0002] Ductile iron pipes are pipes made by adding spheroidizing agent to molten iron and then centrifugally casting it in a centrifugal ductile iron casting machine at high speed. They are mainly used for the transportation of tap water. In the water supply industry, ductile iron is mainly used as the main pipe fittings. In the production process of ductile iron pipes, protective coatings need to be sprayed on the outer wall of the pipes.

[0003] In the process of realizing the present utility model, the inventors found that the following problems in the prior art have not been solved: the existing spraying device for the production of ductile iron pipes does not have a good quick-disassembly and quick-assembly function. The existing device requires manpower to adjust the clamping mechanism first. After clamping and painting, it still requires manpower to loosen and adjust. There are many painting steps, which indirectly affects the painting efficiency and is in urgent need of improvement. Therefore, we propose a spraying device for the production of ductile iron pipes.

[0008] A slider is fixedly installed on one side of the limit strip a, and the slider is movably positioned in the slide rail, and the slide rail is fixed on the rotating plate. An inner rod is fixedly installed at the bottom of the limit strip a, and there are eight sets of inner rods. A spring is sleeved on the outer side of the inner rod, and the inner rod movably passes through the limit strip b;

During the use of the spraying device for ductile iron pipe production, the limit strip can be driven inward by the transmission shaft of the push rod motor b. Since the limit strip has an inclined portion, the limit strip a is pressed inward. When the limit strip enters the pipe body, several groups of springs and anti-slip pads provide internal clamping, and then the push rod motor a drives the pipe body to move upward, and then the drive motor drives the pipe body to rotate. After a single group of pipe bodies is painted, the reverse operation can be performed to adjust.

A rotating plate 3 is placed on the top of the support platform 2, and a supporting plate 4 is fixedly installed on the inner side of the upper surface of the two groups of carrier plates 1; a push rod motor a21 is fixedly installed on the upper surface of the support platform 2, a push rod motor b22 is fixedly installed on the top of the transmission shaft of the push rod motor a21, a drive motor 23 is fixedly installed on the inner side of the transmission shaft of the push rod motor b22, and a rotating plate 3 is fixedly installed on the transmission shaft of the drive motor 23; a limit strip b3 is fixedly installed on the bottom of one side of the rotating plate 3 7, and a limit strip a33 is placed on the other side of the rotating plate 3, and the outer sides of the limit strip a33 and the limit strip b37 are fixedly installed with anti-slip pads 34; a slider 32 is fixedly installed on one side of the limit strip a33, and the slider 32 is movably positioned in the slide rail 31, and the slide rail 31 is fixed on the rotating plate 3, and an inner rod 35 is fixedly installed at the bottom of the limit strip a33, and there are eight groups of inner rods 35, and a spring 36 is sleeved on the outer side of the inner rod 35, and the inner rod 35 movably passes through the limit strip b37; pipe grooves are opened on the upper surfaces of the two groups of supporting plates 4, and a pipe body 42 is placed in the pipe grooves, an L-shaped block 41 is fixedly installed on the outer side of the supporting plate 4, and the end of the L-shaped block 41 is positioned at the outer side of the bottom of the pipe body 42. In the process of removing the clamping mechanism, the pipe body 42 can be limited by the L-shaped block 41 to facilitate the complete removal of the two groups of clamping mechanisms.

[0024] In this technical solution, the limit bar, the turn plate 3 and the drive motor 23 and other components can be used in conjunction. During the use of the spraying device for ductile iron pipe production, the limit bar can be driven inward by the transmission shaft of the push rod motor b22. Since the limit bar has an inclined portion, the limit bar a33 is pressed inward. When the limit bar enters the tube body 42, several groups of springs 36 and anti-slip pads 34 provide internal clamping. Then the push rod motor a21 drives the tube body 42 to move upward, and then the drive motor 23 drives the tube body 42 to rotate. After the single group of tube bodies 42 is painted, the reverse operation can be performed. Compared with the existing method, the paint pretreatment and post-painting operation procedures can be simplified, and the painting effect can be indirectly improved.

[0025] In some technical solutions, an electric push rod 5 is placed at the bottom between the two groups of carrier plates 1, and the electric push rod 5 and the drive shaft of the electric push rod 5 are respectively fixedly connected to the carrier plate 1 on the same side. The four corners of the bottom of the carrier plate 1 are rotatably connected to the universal wheel 11 through the wheel frame.

There are two groups of guide rods 51, and the guide rods 51 are movably inserted into the preset guide groove 52 in the carrier plate 1 on the same side. The guide rods 51 can provide support and guidance effects for the carrier plate 1 in the guide groove 52, thereby indirectly improving the stability of the device operation.

[0026] In this technical solution, the electric push rod 5 and the universal wheel 11 and other components can be used in conjunction, and the transmission shaft of the electric push rod 5 can be extended and retracted. Since the carrier plate 1 is supported by the universal wheel 11, the two groups of carrier plates 1 can move toward or oppositely, thereby adjusting the spacing between the clamping mechanisms on both sides. The adjustment is made according to the length of a single batch of tubes, and the versatility is strong.

[0027] Working principle: It should be noted that the utility model is a spraying device for the production of ductile iron pipes. The components are all universal standard parts or components known to those skilled in the art. The structure and principle can be known to those skilled in the art through technical manuals or conventional test methods.

[0028] When a spraying device for producing ductile iron pipes is used, the spraying device is placed in the ductile iron pipe processing area and the device is connected to an external power supply. During this period, the device can provide a clamping and rotating effect on the pipe body 42, providing a handheld spray gun for the person to perform the painting operation;

[0029] By setting a limit strip, a rotating plate 3 and a driving motor 23, during the use of the spraying device for ductile iron pipe production, the limit strip can be driven inward by the transmission shaft of the push rod motor b22. Since the limit strip has an inclined portion, the limit strip a33 is pressed inward. When the limit strip enters the tube body 42, several groups of springs 36 and anti-slip pads 34 provide internal clamping. Then the push rod motor a21 drives the tube body 42 to move upward, and then the driving motor 23 drives the tube body 42 to rotate. After a single group of tube bodies 42 are painted, the reverse operation can be adjusted. Compared with the existing method, the paint pretreatment and post-painting operation procedures can be simplified, and the paint effect can be indirectly improved. By providing an electric push rod 5 and a universal wheel 11, the drive shaft of the electric push rod 5 can be extended and retracted. Since the carrier plate 1 is supported by the universal wheel 11, the two groups of carrier plates 1 can move toward or oppositely, thereby adjusting the spacing between the clamping mechanisms on both sides, which is adjusted according to the length of a single batch of tube bodies and has strong versatility.
