AI Technical Summary
In the existing cast iron pipe production process, the deflecting device is prone to deflecting multiple cast iron pipes at once, which increases labor intensity and safety hazards, and the deflecting effect is not good, reducing production efficiency.
The system employs a dual-stage shifting mechanism, comprising a first shifting mechanism and a second shifting mechanism. The first and second shifting plates are driven by hydraulic cylinders, respectively, and are automated through a PLC controller. This ensures that only one cast iron pipe is shifted at a time and then transferred to the next process station.
It effectively avoids the situation of moving multiple cast iron pipes at the same time, reduces labor intensity and safety hazards, improves production efficiency, and can adapt to cast iron pipes of various diameters, realizing flexible switching between automated and manual operation.

Description
Technical Field
[0001] This utility model relates to the technical field of cast iron pipe production equipment, and in particular to a cast iron pipe blocking and pushing device. Background Technology
[0002] The production process of cast iron pipes involves multiple steps, including pipe cutting, chamfering, internal grinding, lining, hydrostatic testing, rounding, and spraying. The cast iron pipes need to be sequentially transported to different workstations for processing. Due to the varying processing times at each workstation, the finished pipes from one workstation tend to stack at the front of the next workstation, forming a pipe pile. Once the pipes are stacked, a deflector device is needed to separate them.
[0003] Currently, the deflector device uses a single deflector mechanism, which may result in multiple cast iron pipes being deflected at once, requiring manual operation, increasing labor intensity and safety hazards, and reducing production efficiency. Furthermore, the current deflector device only uses a small protrusion at one end to deflect the pipes, resulting in poor deflection effectiveness. Utility Model Content

[0042] like Figure 1 As shown in the figure, the present invention provides a cast iron pipe blocking and deflecting device, which includes: a frame 2 and a first blocking and deflecting mechanism and a second blocking and deflecting mechanism installed on the frame 2.

The telescopic end of the first hydraulic cylinder 3 extends and retracts, which can drive the first deflector plate 4 to rotate around the first hinge shaft 9.
[0044] like Figure 2 As shown, the first stop plate 4 has a first mounting hole 403 for connecting with the first hinge shaft 9; the first stop plate 4 has a first stop end 401, a first push end 402 and a first connecting end; the first stop end 401 and the first push end 402 form an obtuse angle and are spread out at a large angle to accommodate cast iron pipes 1 of various diameters; the first connecting end has a second connecting hole 404 for connecting with the telescopic end of the first hydraulic cylinder 3.
[0045] The second deflector mechanism includes: a second hydraulic cylinder 5 and a second deflector plate 6; the second hydraulic cylinder 5 is installed on the foundation ground and faces upward; the telescopic end of the second hydraulic cylinder 5 is hinged to the second deflector plate 6; the second deflector plate 6 is movably mounted on a second hinge shaft 10, and the second hinge shaft 10 is mounted on the frame 2. The telescopic end of the second hydraulic cylinder 5 extends and retracts, which can drive the second deflector plate 6 to rotate around the second hinge shaft 10.
[0046] like Figure 3 As shown, the second stop plate 6 has a third mounting hole 603; the second stop plate 6 has a second stop end 601, a second push end 602, and a second connecting end; the second stop end 601 and the second push end 602 form an obtuse angle, and the second stop end 601 and the second push end 602 are spread out at a large angle to accommodate cast iron pipes 1 of various diameters; a fourth connecting hole 604 is provided on the second connecting end, and the fourth connecting hole 604 is used to connect with the telescopic end of the second hydraulic cylinder 5.
[0047] In this embodiment, the blocking and pushing parts of the first stop plate 4 and the second stop plate 6 are integrally formed and are driven by hydraulic cylinders to rotate around the hinge axis, which can realize the blocking and pushing of the cast iron pipe 1.
[0048] The frame 2 is provided with a first V-groove 11. A stop block 13 is provided at the end of the frame 2, and a second V-groove 12 is provided at the front end of the stop block 13. The cast iron pipe 1 can be stably placed in the second V-groove 12, and the stop block 13 can prevent the cast iron pipe 1 from falling.
[0049] The frame 2 is arranged in a direction perpendicular to the line connecting the two idlers 7, and one or more sets can be arranged; the first V-groove 11 is on the same straight line as the idler 7, and the first V-groove 11 can adapt to the shape of the idler 7 so that the idler 7 can support the cast iron pipe 1. Figure 4 As shown, roller seats 8 are provided at both ends of the roller 7, and the roller seats 8 are mounted on the roller support mechanism.
[0050] like Figure 5 As shown, the oil sources of the first hydraulic cylinder 3 and the second hydraulic cylinder 5 are electrically connected to a PLC controller, which can be installed in an electrical control cabinet. The PLC controller is electrically connected to a visual touchscreen and operation buttons; the visual touchscreen and operation buttons are integrated on the control panel. The equipment of this invention can be automatically controlled by the PLC controller and simultaneously manually controlled via buttons on the control panel.
[0051] A first laser rangefinder is installed above the first stop plate 4. This rangefinder detects whether a cast iron pipe 1 is on the first stop plate 4 and sends a signal to the PLC controller upon detection. Similarly, a second laser rangefinder is installed above the second stop plate 6. This rangefinder detects whether a cast iron pipe 1 is on the second stop plate 6 and sends a signal to the PLC controller upon detection.

Simultaneously, timed operation can be performed on the touchscreen display to set the stop-shifting interval. These multiple control options better adapt to complex production processes.
[0053] The working principle of this utility model of a cast iron pipe blocking and pulling device is as follows: The cast iron pipe 1 is conveyed by a conveyor belt. Before the cast iron pipe 1 is conveyed, such as... Figure 6 As shown, the first hydraulic cylinder 3 is in the extended state, causing the first stop plate 4 to be in the pipe-blocking state; the second hydraulic cylinder 4 is in the retracted state, causing the second stop plate 6 to be in the pipe-blocking state. The cast iron pipe 1 is fed onto the first stop plate 4, and the first pipe-blocking end 401 blocks the cast iron pipe 1, stopping its feeding. At this time, the first laser rangefinder detects the signal from the cast iron pipe 1 and sends it to the PLC controller. The PLC controller controls the first hydraulic cylinder 3 to retract, and the first stop plate 4 rotates, passing through the first pipe-blocking end 402 to push the cast iron pipe 1 backward for continued feeding. Figure 7 As shown. The cast iron pipe 1 is conveyed to the second stopper 6. The second stopper end 601 of the second stopper 6 blocks the cast iron pipe 1, stopping its conveying. At this time, the cast iron pipe 1 stops on the idler roller 7. The second laser rangefinder detects the signal from the cast iron pipe 1 and sends it to the PLC controller. The PLC controller controls the second cylinder 5 to extend, and the second stopper 6 rotates, passing through the second stopper end 602 to propel the cast iron pipe 1 forward for continued conveying. If the first laser rangefinder does not detect a signal, the first cylinder 3 resets; if the second laser rangefinder does not detect a signal, the second cylinder 5 resets, preparing for another stopper and propulsion. When the cast iron pipe 1 rolls to the device of this invention, it can stop and be removed from the pipe stack for transmission to the subsequent production station.
[0054] This utility model provides a second deflector mechanism based on the first deflector mechanism. The first deflector mechanism can deflect the cast iron pipe 1 from the pipe stack, and the second deflector mechanism can transfer the cast iron pipe 1 deflected by the first deflector mechanism to the next process station, thus avoiding the situation of deflecting multiple cast iron pipes at once.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
