[0016] A two-stage driven ductile iron pipe socket zinc spraying device and a zinc spraying method thereof, comprising the following steps:

[0017] S1: After the ductile iron pipe is transferred to a point corresponding to the top of the second stabilizing frame by the transfer device, the ductile iron pipe is longitudinally transferred toward the zinc spraying assembly by the longitudinal transfer device on the transfer device, so that the socket of the ductile iron pipe is transferred to the top of the second stabilizing frame;

[0018] S2: The hydraulic cylinder drives the sliding frame to slide upward on the side of the second stabilizing frame away from the second tooth plate, so that the arc-shaped swing frame abuts against the ductile iron pipe body, so that the arc-shaped swing frame is behind the socket of the ductile iron pipe;

[0019] S3: The motor drives the gear column to rotate at the bottom of the relative slide groove, and the gear plate 2 is meshed with the gear column to drive the gear plate 2 to slide inside the relative slide groove at the bottom of the main body, thereby driving the sliding frame to slide on the lifting slide rod through the limit lifting frame, so that the abutting mechanism moves synchronously with the gear plate 2;

[0020] S4: Since the diameter of the socket of the ductile iron pipe is larger than the diameter of the pipe body, the arc-shaped swing frame will abut against the rear wall of the socket of the ductile iron pipe during the movement of the abutting mechanism, thereby pushing the ductile iron pipe to move to one side of the zinc spraying assembly.

[0021] The present invention has the following beneficial effects:

[0022] The cam is moved along the axis of the two guide rails, and the two guide rails are moved along the axis of the two guide rails, so that the guide rails move along the axis of the two guide rails, and the guide rails move along the axis of the two guide rails, so that the guide rails move along the axis of the two guide rails, and the guide rails move along the axis of the two guide rails, so that the guide rails move along the axis of the two guide rails, and the guide rails move along the axis of the two guide rails, so that the guide rails move along the axis of the two guide rails, and the guide rails move along the axis of the two guide rails, so that the guide rails move along the axis of the two guide rails, and the guide rails move along the axis of the two guide rails, so that the guide rails move along the axis of the two guide rails,

[0023] (2) The present invention transmits the ductile iron pipe to a point corresponding to the top of the second stabilizing frame through the transmission device, and then transmits the ductile iron pipe longitudinally toward the zinc spraying assembly through the longitudinal transmission device on the transmission device. When the socket of the ductile iron pipe is transmitted to the top of the second stabilizing frame, the sliding frame is driven by the hydraulic cylinder to slide upward on the side of the second stabilizing frame away from the second tooth plate, so that the arc-shaped swing frame is against the body of the ductile iron pipe, so that the arc-shaped swing frame is behind the socket of the ductile iron pipe, and then the gear column is driven by the motor to rotate at the bottom of the relative slide groove, and the gear plate is driven to rotate at the bottom of the main body through the meshing of the second tooth plate and the gear column. The relative slide groove slides inside, thereby driving the sliding frame to slide on the lifting slide rod through the limit lifting frame, so that the abutting mechanism moves synchronously with the tooth plate 2. Since the diameter of the socket of the ductile iron pipe is larger than the diameter of the pipe body, the arc-shaped swing frame and the rear wall of the socket of the ductile iron pipe will be abutted during the movement of the abutting mechanism, thereby pushing the ductile iron pipe to one side of the zinc spraying component, avoiding the slipping phenomenon when the pipe body is longitudinally transmitted through the transmission device, which affects the transmission of the ductile iron pipe to the zinc spraying component, thereby improving the efficiency of zinc spraying at the socket of the ductile iron pipe and improving the practicability of the device.

[0024] (3) After the arc surface at the top of the arc-shaped swing frame of the present invention contacts the pipe body, the sliding frame will continue to slide upward so that the arc-shaped swing frame and the pipe body are pressed against each other, pushing the slide rod to slide downward through the slide hole bar, and stretching the tension spring. The arc-shaped swing frames in the four abutting mechanisms are respectively abutted against different positions of the pipe body, so that the four arc-shaped swing frames are pressed down to different depths, so that thrust can be applied to multiple areas behind the socket of the ductile iron pipe, thereby improving the stability of the arc-shaped swing frame pushing the rear of the socket of the ductile iron pipe and reducing the phenomenon of the arc-shaped swing frame and the socket of the ductile iron pipe slipping off. When one end of the arc surface at the top of the arc-shaped swing frame abuts against the pipe body behind the socket of the ductile iron pipe, the pressure applied at one end of the arc-shaped swing frame will cause the arc-shaped swing frame to rotate at the end of the slide rod away from the slide hole strip, so that the arc-shaped swing frame will tilt toward one side of the pipe body, and the connecting head at the inclined end will apply a thrust to the double-headed sliding block through the strip hole strip, so that the double-headed sliding block slides downward inside the downward pressure slide groove and squeezes the downward pressure spring, so that the center of the top of the arc-shaped swing frame can abut against the pipe body, thereby improving the stability of the arc-shaped swing frame when pushing the rear of the socket of the ductile iron pipe.

The arc-shaped swing frames 405 in the four opposing mechanisms 4 are respectively pressed against different positions of the pipe body, so that the four arc-shaped swing frames 405 are pressed down to different depths, so that thrust can be applied to multiple areas behind the socket of the ductile iron pipe. When one end of the arc surface at the top of the arc-shaped swing frame 405 is pressed against the pipe body behind the socket of the ductile iron pipe, the arc-shaped swing frame 405 at one end will be pressed against the pipe body behind the socket of the ductile iron pipe.

[0046] Example 2, please refer to Figure 1-Figure 9 As shown, when in use, the ductile iron pipe is transmitted to a place corresponding to the top of the second stabilizing frame 303 by the transmission device, and then the ductile iron pipe is longitudinally transmitted to the direction of the zinc spraying component 207 by the longitudinal transmission device on the transmission device. When the ductile iron pipe socket is transmitted to the top of the second stabilizing frame 303, the sliding frame 304 is driven by the hydraulic cylinder 107 to slide upward on the side of the second stabilizing frame 303 away from the second tooth plate 302, so that the arc swing frame 405 is against the ductile iron pipe body, so that the arc swing frame 405 is behind the socket of the ductile iron pipe, and then the gear column 103 is driven by the motor 109 to rotate at the bottom of the relative slide groove 101, and the gear plate 302 is driven to rotate. The meshing with the gear column 103 drives the tooth plate 2 302 to slide inside the relative slide groove 101 at the bottom of the main body 1, thereby driving the sliding frame 304 to slide on the lifting slide rod 501 through the limit lifting frame 305, so that the abutting mechanism 4 moves synchronously with the tooth plate 2 302. Since the diameter of the socket of the ductile iron pipe is larger than the diameter of the pipe body, the arc-shaped swing frame 405 and the rear wall of the socket of the ductile iron pipe will be abutted during the movement of the abutting mechanism 4, thereby pushing the ductile iron pipe to move to one side of the zinc spraying component 207, avoiding the slippage when the pipe body is longitudinally transmitted through the transmission device, which affects the transmission of the ductile iron pipe to the zinc spraying component 207;

[0047] When the motor 109 drives one gear column 103 to rotate, the belts set on the two gear columns 103 drive the two gear columns 103 to rotate simultaneously, so that the tooth plate 1 202 is meshed with the gear column 103 at the top of the main body 1, and the tooth plate 1 202 is driven to move toward one end of the second stabilizing frame 303 inside the relative slide groove 101 at the top of the main body 1, so that the zinc spraying component 207 can be driven to enter the socket of the ink cast iron pipe, and the inner wall of the socket of the ink cast iron pipe is sprayed with zinc during the rotation of the ink cast iron pipe;

[0048] After the arc surface at the top of the arc-shaped swing frame 405 contacts the pipe body, the sliding frame 304 will continue to slide upward so that the arc-shaped swing frame 405 and the pipe body are pressed against each other, pushing the slide bar 401 to pass through the slide hole strip 306 and slide downward, and stretching the tension spring 402. The arc-shaped swing frames 405 in the four abutting mechanisms 4 are respectively abutted against different positions of the pipe body, so that the four arc-shaped swing frames 405 are pressed down to different depths, so that thrust can be applied to multiple areas behind the socket of the ductile iron pipe, thereby improving the stability of the arc-shaped swing frame 405 pushing the rear of the socket of the ductile iron pipe, reducing the phenomenon of the arc-shaped swing frame 405 and the socket of the ductile iron pipe slipping, and when the arc-shaped swing frame 4 When one end of the arc surface at the top of 05 abuts against the pipe body behind the socket of the ductile iron pipe, the pressure applied at one end of the arc swing frame 405 will cause the arc swing frame 405 to rotate at the end of the slide rod 401 away from the slide hole strip 306, so that the arc swing frame 405 is tilted to one side of the pipe body, and the connecting head 406 at one inclined end applies a thrust to the double-headed sliding block 408 through the strip hole strip 407, so that the double-headed sliding block 408 slides downward inside the downward pressure slide groove 403, squeezing the downward pressure spring 404, so that the center of the top of the arc swing frame 405 can be abutted against the pipe body, thereby improving the stability of the arc swing frame 405 when pushing the rear of the socket of the ductile iron pipe.

[0049] A two-stage driven ductile iron pipe socket zinc spraying device and a zinc spraying method thereof, comprising the following steps:

[0050] S1: After the ductile iron pipe is transferred to a position corresponding to the top of the second stabilizing frame 303 by the transfer device, the ductile iron pipe is transferred longitudinally toward the zinc spraying assembly 207 by the longitudinal transfer device on the transfer device, so that the socket of the ductile iron pipe is transferred to the top of the second stabilizing frame 303;

[0051] S2: The hydraulic cylinder 107 drives the sliding frame 304 to slide upward on the side of the second stabilizing frame 303 away from the second tooth plate 302, so that the arc swing frame 405 abuts against the ductile iron pipe body, so that the arc swing frame 405 is behind the socket of the ductile iron pipe;

[0052] S3: The motor 109 drives the gear column 103 to rotate at the bottom of the relative slide groove 101, and the gear plate 2 302 is meshed with the gear column 103, driving the gear plate 2 302 to slide inside the relative slide groove 101 at the bottom of the main body 1, thereby driving the sliding frame 304 to slide on the lifting slide rod 501 through the limit lifting frame 305, so that the abutting mechanism 4 moves synchronously with the gear plate 2 302;

[0053] S4: Since the diameter of the socket of the ductile iron pipe is larger than the diameter of the pipe body, the arc-shaped swing frame 405 will abut against the rear wall of the socket of the ductile iron pipe during the movement of the abutting mechanism 4, thereby pushing the ductile iron pipe to move to one side of the zinc spraying assembly 207.
