[0031] An electric hydraulic pump 17 is fixedly provided in the middle of the upper side of the core back 5, and batteries 18 are symmetrically provided on both sides of the upper side of the core back 5. The batteries 18 are lead-acid batteries. A controller 19 is fixedly provided on the electric hydraulic pump 17. The controller 19 and the electric hydraulic pump 17 are electrically connected, and the controller 19 and the battery 18 are electrically connected.

[0032] A reinforcing plate 20 is fixedly provided between the core back 5 and the side wing 9 on the core inverted U-shaped bracket 4 .

[0033] Preparation:

[0034] Check whether all components are intact, ensure that the core rope 1 is not broken or worn, and that the auxiliary lifting ring 2 is firmly fixed to the middle of the core rope 1.

[0035] Check the various components of the grabbing part 3 at the edge of the ductile iron pipe, including whether the core inverted U-shaped bracket 4 is stable, whether the connection between the arc plate 6 and the core back 5 is tight, whether the core lifting ring 7 is well fixed, whether the connection between the L-shaped side limit plate 8 and the core back 5 is firm, whether the secondary support plate 11 at the core notch 10 rotates flexibly, whether the connection of the secondary hydraulic rod 16 is reliable, whether the electrical connection between the electric hydraulic pump 17, the battery 18 and the controller 19 is normal, and whether the reinforcing plate 20 is firmly connected between the core back 5 and the side wing 9.

[0036] Grabbing ductile iron pipes:

[0037] Near the edge of the ductile iron pipe:

[0038] The user uses other auxiliary equipment to move the gripping portion 3 at the edge of the ductile iron pipe to the edge of the ductile iron pipe.

[0039] In the initial state, the user operates the controller 19 to shorten the electric hydraulic pump 17. This causes the secondary hydraulic rod 16 to retract, causing the outer plate 14 of the secondary support plate 11 to rotate upward while the inner plate 13 of the secondary support plate 11 rotates downward. This causes the two inner plates 13 to unfold, extending parallel to the direction of the wing portions 9. At this point, the secondary support plate 11 resembles an open pair of pliers.

[0040] Positioning and fixing the edge of ductile iron pipe:

[0041] With the two inner plates 13 deployed, other auxiliary equipment continues to control the movement of the ductile iron pipe edge gripping portion 3, causing the vertical portion of the L-shaped side retaining plate 8 to slowly approach and abut the ductile iron pipe edge. When the ductile iron pipe edge gripping portion 3 is located within the core inverted U-shaped bracket 4, the ductile iron pipe edge is initially positioned by the L-shaped side retaining plate 8. The lateral portion of the L-shaped side retaining plate 8 is fixedly connected to the outer side of the core back 5, while the vertical portion extends downward, preventing the ductile iron pipe edge from moving horizontally.

[0042] Clamp the edge of the ductile iron pipe:

[0043] The user operates the controller 19 again to control the extension of the electric hydraulic pump 17. At this time, the secondary hydraulic rod 16 extends, pushing the outer plate 14 of the secondary support plate 11 to rotate downward, while driving the inner plate 13 of the secondary support plate 11 to rotate upward. The two inner plates 13 shrink and approach the lower side of the edge of the ductile iron pipe. The support pad 15 on the upper side of the inner plate 13 contacts the lower side of the edge of the ductile iron pipe, playing a role in supporting and protecting the paint on the lower side of the edge of the ductile iron pipe. At the same time, the vertical part of the L-shaped side limit plate 8 continues to press against the edge of the ductile iron pipe, limiting the sliding of the edge of the ductile iron pipe on the gripping part 3 at the edge of the ductile iron pipe, thereby achieving a firm grip on the ductile iron pipe.

[0044] Lifting ductile iron pipes:

[0045] The crane hooks onto the auxiliary lifting ring 2 in the middle of the core rope 1 and lifts the ductile iron pipe to the designated location. During the lifting process, the edge of the ductile iron pipe is firmly grasped in the ductile iron pipe edge gripping portion 3, and the core rope 1 has sufficient strength and stability to ensure that the ductile iron pipe is safely lifted to the destination.

[0046] Release ductile iron pipe:

[0047] After the ductile iron pipe has been hoisted to the designated location, it needs to be released. At this point, the pipe is slowly lowered, allowing its bottom to contact the ground or other support. The user then operates the controller 19 to shorten the electric hydraulic pump 17, causing the outer plate 14 of the secondary support plate 11 to rotate upward and the inner plate 13 of the secondary support plate 11 to rotate downward, unfolding the two inner plates 13. This removes support from the edges of the pipe, allowing the pipe to be released. After release, the next grabbing operation can be performed.

[0048] Improved security:

[0049] By automating the grabbing and handling process, the need for manual operation is reduced, lowering the risk of worker injury during handling.

[0050] The L-shaped side limit plates 8 and support pads 15 in the design ensure the stability of the ductile iron pipe during the process of grabbing and carrying, and prevent damage caused by falling off and collision.

[0051] Improve work efficiency:

[0052] The combined use of the electric hydraulic pump 17 and the secondary hydraulic rod 16 enables a fast grabbing and releasing function, speeds up the handling speed, and improves the overall efficiency of the production line.

[0053] Through the remote operation of the controller 19, the operator's physical labor is reduced, making the operation more convenient and efficient.

[0054] Strong adaptability:

[0055] The adjustable design of the secondary support plate 11 enables it to adapt to ductile iron pipes of different sizes, thereby enhancing the flexibility and adaptability of the equipment.

[0056] By adjusting the angle of the secondary support plate 11, ductile iron pipes of different diameters and lengths can be easily handled.

[0057] Stable structure:

[0058] The combination of the core inverted U-shaped bracket 4 and the reinforcing plate 20 provides a stable support structure, ensuring the stability of the equipment during operation.

[0059] The arrangement of the arc-shaped plate 6 and the core suspension ring 7 further enhances the rigidity and reliability of the overall structure.

[0060] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
