[0002] In the processing of ductile iron pipe production line, the cast pipe needs to go through a series of processing steps at multiple stations, such as cleaning, inspection, grinding, coating, etc. In order to ensure production efficiency and processing quality of cast pipe, cast pipe needs to be shifted between these stations. However, in the existing ductile iron pipe production line, the displacement of cast pipe usually needs to rely on manual operation or lifting equipment, but manual operation is not only inefficient, but also prone to collision, wear or deformation of cast pipe during displacement due to unstable human factors, thus affecting the quality and production efficiency of cast pipe. In addition, manual displacement also has safety risks and may cause harm to operators. Although the existing lifting equipment can realize the automatic displacement of cast pipe, most of the equipment has a complex structure and high production cost. At the same time, the maintenance of these equipment is also difficult, and professional personnel are required to perform regular inspection and maintenance, which undoubtedly increases the operating cost of the production line.

[0021] The present invention is further described in detail below in conjunction with the embodiments:

[0022] like Figure 1 and Figure 2 As shown, the utility model provides a ductile iron pipe station stepping device, comprising a control box 1 and a guide mechanism, a driving mechanism, a displacement device 2 and a lifting device 3 arranged on the control box 1, the driving mechanism is arranged on one side of the control box 1, the displacement device 2 is connected to the driving mechanism and moves horizontally along the guide mechanism under the drive of the driving mechanism, the lifting device 3 is arranged on the displacement device 2 and moves vertically under the drive of the driving mechanism, and the operation of the driving mechanism is controlled by the control box.

[0023] Specifically, the driving mechanism includes a gear 4 and a driving plate 5. The driving plate 5 is a rectangular structure, and a ring-shaped tooth groove with the tooth tip facing inward is opened in the center. The driving plate 5 is meshed with the gear 4 through the ring-shaped tooth groove. The gear 4 is connected to the motor 1-1 in the control box 1 through a transmission shaft. The driving plate 5 is vertically slidably connected to the displacement device 2, and the lifting device 3 is fixedly connected to the top of the driving plate 5. Preferably, the ring-shaped tooth groove is an oblong bar or an ellipse. When the annular tooth groove is an ellipse, the motion trajectory of the lifting device 3 is an ellipse. When the annular tooth groove is an oblong bar, the motion trajectory of the lifting device 3 is an oblong bar. The oblong bar-shaped annular tooth groove has two upper and lower parallel straight lines and semicircular arcs at both ends of the two straight lines, so the motion trajectory of the lifting device 3 is the best. The longitudinal and transverse dimensions of the annular tooth groove need to meet the requirements of the lifting device 3 to complete the displacement of the pipe between the two stations. When the motor 1-1 drives the gear 4 to rotate, the driving plate 5 meshing with the gear 4 through the annular tooth groove can slide vertically relative to the displacement device 2 under the drive of the gear 4. At the same time, the driving plate 5 can also drive the displacement device 2 to move horizontally along the guide mechanism. Therefore, the lifting device 3 arranged on the driving plate 5 can realize the function of lifting and shifting the pipe fitting under the cooperation of the driving plate 5 and the displacement device 2.

[0024] Vertical slide grooves 2-1 are provided on both sides of the displacement device 2, and the driving plate 5 is slidably connected to the displacement device 2 through the two vertical slide grooves 2-1, so that the driving plate 5 can move up and down along the two vertical slide grooves 2-1 of the displacement device 2 under the drive of the gear 4. Preferably, the displacement device 2 is a rectangular frame structure, and the two vertical slide grooves 2-1 are both arranged on the inner walls on both sides thereof, and the driving plate 5 is slidably arranged inside the displacement device 2 through the two vertical slide grooves 2-1.

[0025] The guide mechanism includes a guide rod 6 horizontally arranged on the control box 1 and stop blocks 7 respectively arranged at both ends of the guide rod 6. The guide rod 6 penetrates the two side walls of the displacement device 2, so that the driving plate 5 drives the displacement device 2 to move horizontally on the guide rod 6 under the drive of the gear 4.

[0026] The lifting device 3 includes a support rod 3-1 that passes through the displacement device 2 and is connected to the top of the driving plate 5, and a lifting plate 3-2 arranged on the top of the support rod 3-1. The top surface of the lifting plate 3-2 is provided with a groove adapted to the curvature of the pipe. A guide beam 8 located above the guide rod 6 is horizontally arranged on the control box 1, and a roller 9 adapted to the guide beam 8 is arranged on the support rod 3-1. When the lifting device 3 moves along the rectangular motion trajectory, the roller 9 moves along the outer periphery of the guide beam 8 to play a guiding role.

[0027] like Figure 3 As shown, when performing the pipe lifting and shifting operation, the following steps are included:

[0028] Step S1: the motor 1-1 controls the gear 4 to rotate clockwise, causing the driving plate 5 to move upward along the vertical slide groove 2-1 relative to the displacement device 2. At this time, the gear 4 is located at the lower right side of the driving plate 5, and the lifting device 3 that moves upward with the driving plate 5 lifts the pipe at the workstation 1;

[0029] Step S2: The gear 4 rotates clockwise to cause the driving plate 5 to drive the displacement device 2 to move horizontally to the right along the guide rod 6. At this time, the gear 4 is located at the lower left of the driving plate 5, and the lifting device 3 that moves horizontally to the right with the driving plate 5 lifts the pipe to the second station;

[0030] Step S3: The clockwise rotating gear 4 causes the driving plate 5 to move downward along the vertical slide groove 2-1 relative to the displacement device 2. At this time, the gear 4 is located at the upper left of the driving plate 5. The lifting device 3 that moves downward following the driving plate 5 places the pipe fitting at the second station, completing the displacement of the pipe fitting.

[0031] Step S4: The clockwise rotating gear 4 prompts the driving plate 5 to drive the displacement device 2 to move horizontally to the left along the guide rod 6. At this time, the gear 4 is located at the upper right side of the driving plate 5. The lifting device 3 that moves horizontally to the left with the driving plate 5 returns to station 1 to prepare for the next pipe lifting and displacement.

[0032] The utility model can realize automatic lifting and displacement of pipe fittings, has a simple structure and saves time and effort, can effectively save economic and labor costs, and improve the production efficiency of the pipe fitting production line, and at the same time can effectively avoid the occurrence of safety accidents.
