Description

Technical Field

[0002] Ductile iron pipes are pipes made by centrifugally casting molten iron of grade 18 or higher with the addition of spheroidizing agents using a centrifugal ductile iron casting machine at high speed. They are also known as ductile iron pipes or ductile cast pipes, and are mainly used for the transportation of tap water, making them an ideal material for tap water pipelines.

[0003] Existing roller support mechanisms, such as the roller support device disclosed in application number CN202222334597.6 for spraying anti-corrosion paint on the outer wall of ductile iron pipes, include inclined stepped rollers respectively set below the ductile iron pipe spigot and socket. Multiple inclined stepped rollers are horizontally arranged on a U-shaped support. A roller shaft is fixedly set at the center of each inclined stepped roller, passing through both ends of the U-shaped support and connected to the U-shaped support via bearings. One roller shaft is connected to a motor via a coupling. A roller flange is fixedly set at the end of each inclined stepped roller. However, in the above technology, the cams are parallelly distributed, which can easily cause the pipe to get stuck at the roller spacing during operation, hindering rapid transportation.

[0019] 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.

[0020] according to Figure 1-4 As shown, this embodiment proposes a roller support mechanism for the production of ductile iron pipes, including a movable pressure reducing component 1 and a transfer output component 4.

[0022] The pneumatic telescopic rod 404 and the wheel sleeve shell 405 are distributed at equal angles around the central axis of the ring shell 403.

[0023] In this embodiment, the pneumatic telescopic rod 404 on the ring shell 403 then outputs power to drive the output end to run, so that the wheel sleeve shell 405 and the electric guide wheel 406 fit against the ductile iron pipe body 5 and drive the ductile iron pipe body 5 to the target location.

[0024] The mobile pressure relief assembly 1 includes a mobile wheel 101, a wheel plate 102, a frame 103, a hydraulic hinge arm 104, and a pressure relief pad 105. The top side of the mobile wheel 101 is provided with a wheel plate 102, and the top side of the wheel plate 102 is provided with a frame 103 connected by bolts. The two ends of the frame 103 are provided with hydraulic hinge arms 104, and the output end of the hydraulic hinge arm 104 is provided with a pressure relief pad 105.

[0025] In this embodiment, when in use, the device is moved to a suitable target location by the movable wheel 101 below the wheel plate 102. After moving to the target location, the hydraulic hinge arm 104 on the frame 103 outputs power to drive the output end to run, so that the pressure relief pad 105 is supported on the ground.

[0026] The steering mechanism 2 includes a vehicle plate 201, an electric rotating column 202, a rotating plate 203, and an arc-shaped support shell 204.

The arc-shaped support shell 204 is provided below the middle part of the rotating plate 203.

[0027] In this embodiment, when steering adjustment is required, the electric rotating column 202 on the vehicle plate 201 outputs power to drive the output end to run, so that after the electric rotating column 202 outputs power, the rotating plate 203 above the arc-shaped support shell 204 is adjusted to a suitable target orientation location.

[0028] The expansion and contraction displacement mechanism 3 includes a bolt base 301, a housing 302, a drive motor 303, a first gear set 304, a second gear set 305, a lead screw set 306, and a sliding base 307. The bolt base 301 is bolted to the top side of the rotating plate 203. The housing 302 is provided above the bolt base 301, and the drive motor 303 is provided at the outer end of the housing 302.

[0029] In this embodiment, when operation is required, the drive motor 303 on the outer side of one end of the housing 302 outputs power to drive the output end to run, so that the drive motor 303 outputs power to drive the input end of the housing 302 to run.

[0030] The output end of the drive motor 303 is provided with a first gear set 304, and the output end of the first gear set 304 is provided with a second gear set 305.

[0031] In this embodiment, after the input end of the housing 302 is operated, it can drive the first gear set 304 to output transmission operation. After the first gear set 304 outputs transmission operation, the first gear set 304 and the second gear set 305 output transmission operation, which causes the lead screw set 306 to output operation, and then the sliding base 307 moves to a suitable spacing position.

[0032] The working principle of the roller support mechanism used in ductile iron pipe production is as follows: During use, the equipment moves to a suitable target location via the movable wheels 101 below the wheel plate 102. Once at the target location, the hydraulic hinge arm 104 on the frame 103 outputs power to drive the output end, causing the pressure relief pad 105 to support the ground. When steering adjustment is required, the electric rotating column 202 on the wheel plate 201 outputs power to drive the output end, causing the rotating plate 203 above the arc-shaped support shell 204 to adjust to a suitable target orientation. During operation, the drive motor on one side of the housing 302... The motor 303 outputs power to drive the output end, which in turn drives the input end of the housing 302. The input end of the housing 302 then drives the first gear set 304 to output and drive. After the first gear set 304 outputs and drives, it and the second gear set 305 output and drive, which in turn drives the lead screw set 306 to output and drive the sliding base 307 to a suitable distance. Then, the pneumatic telescopic rod 404 on the ring shell 403 outputs power to drive the output end, which causes the wheel housing 405 and the electric guide wheel 406 to fit against the ductile iron pipe body 5 and drive the ductile iron pipe body 5 to the target location.
