[0030] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0031] In conjunction with the accompanying drawings, a ductile iron pipe handling device includes a bottom core support plate 1, with upper support plate bodies 2 symmetrically arranged on both sides of the bottom core support plate 1. A core long rubber pad 3 is fixed to the upper side of the upper support plate body 2, and the extension direction of the core long rubber pad 3 is parallel to the extension direction of the upper support plate body 2. A reinforcement plate 4 is fixed to the inner side of the upper support plate body 2 and the upper side of the bottom core support plate 1.

[0032] A U-shaped rotating seat 5 is fixedly provided at the fixed connection between the upper support plate body 2 and the bottom core support plate 1, and the bottom of the U-shaped rotating seat 5 is fixed at the fixed connection between the upper support plate body 2 and the bottom core support plate 1; the two side wings of the U-shaped rotating seat 5 are rotated by a hinge axis to provide an arc-shaped pressing limit frame 6, and the opening direction of the arc-shaped pressing limit frame 6 is inward, and an auxiliary long rubber pad 7 is fixed at the other end edge of the arc-shaped pressing limit frame 6, and the extension direction of the auxiliary long rubber pad 7 and the extension direction of the core long rubber pad 3 are parallel to each other.

[0033] A bearing seat 8 is fixedly provided on the upper outer side of the upper support plate 2, and a handle screw 9 is provided on the bearing seat 8; a nut 11 is provided inside the arc-shaped pressing limit frame 6 through a rotating shaft 10, and the stud part of the handle screw 9 and the nut 11 are threadedly matched.

[0034] A moving handle 12 is fixedly provided on the front side of the bottom core support plate 1 .

[0035] The bottom core support plate 1 is projected in a rectangular shape when viewed from above. Lower support plate bodies 13 are symmetrically provided on both sides of the bottom core support plate 1. Universal running wheels 14 are symmetrically provided at both ends of the lower support plate body 13. The extension direction of the lower support plate body 13 is parallel to the extension direction of the upper support plate body 2.

[0036] Placement of ductile iron fittings:

[0037] Use relevant lifting equipment to lift the ductile iron pipe fittings and slowly place them on the core long rubber pads 3 fixed on the upper sides of the two upper support plates 2, so that the two ends of the ductile iron pipe fittings are respectively placed on the two ductile iron pipe fitting handling devices 1. During the placement process, ensure that the ductile iron pipe fittings are in full contact with the core long rubber pads 3, and use the cushioning and anti-slip effects of the core long rubber pads 3 to initially stabilize the position of the pipe fittings.

[0038] Fixed ductile iron pipe fittings:

[0039] To ensure the stability of the placement of the ductile iron pipe fitting, the user holds the handle screw 9 to operate. Since the arc-shaped pressing limit frame 6 is provided with a nut 11 through the rotating shaft 10, and the stud portion of the handle screw 9 and the nut 11 are threadedly engaged, when the user rotates the handle screw 9, the handle screw 9 pushes or pulls the nut 11 through the action of the thread.

[0040] The movement of nut 11 drives the arc-shaped pressing and limiting frame 6 to rotate about the hinge axis of the U-shaped rotating seat 5, causing the auxiliary long rubber pad 7 fixed to the other end edge of the arc-shaped pressing and limiting frame 6 to gradually move toward the outside of the ductile iron pipe fitting, ultimately resting against the outside of the ductile iron pipe fitting. The close contact between the auxiliary long rubber pad 7 and the ductile iron pipe fitting further secures the ductile iron pipe fitting from the side, and works together with the core long rubber pad 3 at the bottom to keep the ductile iron pipe fitting stable on the handling device, preventing it from shaking or slipping during handling.

[0041] Transporting: The user grasps the handle 12 fixed to the front of the bottom core support plate 1 and uses the lower support plate 13 on both sides of the bottom core support plate 1 and the universal wheels 14 at both ends to move the transport device, with the ductile iron pipes placed and secured, to the desired location. The universal wheels 14 allow for flexible steering during transport, making it convenient to transport the ductile iron pipes in various locations.

[0042] Enhanced stability:

[0043] The design of this handling device fully considers the need for stability. The combination of the upper support plate 2 and the core long rubber pad 3 provides a strong and soft support surface, which can not only bear the weight of the ductile iron pipe fittings, but also reduce the instability caused by uneven ground. The softness of the core long rubber pad 3 helps to disperse the weight of the pipe fittings and reduce pressure points, thereby protecting the pipe fittings from damage caused by local excessive pressure. The use of the arc-shaped pressing limit frame 6 and the auxiliary long rubber pad 7 can provide additional support and restriction on both sides of the pipe fittings to prevent the pipe fittings from rolling or shifting during transportation. This design ensures that the pipe fittings can remain stable even on uneven ground or encounter bumps during transportation, greatly reducing safety hazards during transportation.

[0044] Reduce the risk of injury:

[0045] In traditional handling methods, pipes come into direct contact with the ground or other hard surfaces, which can not only cause scratches and wear on the pipe surface but also make handling difficult due to excessive friction. This handling device effectively reduces this direct contact by using rubber pads between the pipe and the support plate, significantly reducing the risk of damage. The rubber pads' elasticity and wear resistance cushion the impact and vibration during handling, protecting the pipes from damage. Furthermore, the rubber pads' moderate coefficient of friction ensures smooth handling of the pipes, minimizing accidental damage from sliding or rolling.

[0046] Easy to operate:

[0047] The design of this handling device focuses on user experience, making operation simple and quick. The design of the handle screw 9 and the rotating shaft 10 allows the operator to easily adjust the position of the arc-shaped pressing limit frame 6, achieving rapid fixation and release of the pipe. This design allows even non-professionals to quickly get started without the need for complex training or instructions. In addition, the threaded design ensures the stability and reliability of the fixing and release process. The operator can easily control the movement of the arc-shaped pressing limit frame 6 by simply turning the handle screw 9 to achieve precise fixation of the pipe.

[0048] Flexible mobility:

[0049] To adapt to varying handling environments and conditions, the transport device is equipped with universal wheels 14 beneath the bottom core support plate 1. These wheels allow the transport device to be easily moved in various directions, enabling flexible handling operations in both confined spaces and open areas. The rotational flexibility of the universal wheels 14 ensures stability and smooth steering, reducing resistance and friction during handling. Furthermore, the material and design of the wheels take into account wear resistance and durability, ensuring long-term, stable use.

[0050] 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.
