Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of recycling waste cast iron pipes, in particular to a recycling, utilization, transportation and fixing device for waste cast iron pipes. Background Art
[0002] Ductile iron has developed rapidly since its introduction. Even in the economic downturn, it has continued to develop. In the late 1970s, China, the United States, the Soviet Union, and Finland independently and simultaneously announced their successful research on bainitic ductile iron. In 1977, M. Johanson announced that a Finnish foundry had developed a new type of ductile iron (ductile iron) with excellent performance, also known as Austenitic-Bayer ductile iron. This material subsequently attracted worldwide attention for its excellent properties and was hailed as one of the major achievements in cast iron metallurgy in recent decades. Currently, ductile iron pipes and fittings on the market are mostly cast using lost foam casting, a process with high costs and low pass rates. This process is prone to producing defects such as porosity, casting marks, and heavy skin during production due to process and operational reasons, leading to rejection. Consequently, scrap cast iron pipes have been repurposed into short-length water pipes through research and development, enabling their reuse. However, moving scrap cast iron pipes to other equipment is a relatively difficult task. Currently, transport vehicles are used for transportation, and the forces exerted by these vehicles during movement can easily cause the scrap cast iron pipes to swing from side to side. This swaying behavior can easily break free from the binding ropes and cause them to fall, which can easily lead to unforeseen safety issues. Utility Model Content

When the overall horizontal length of the waste cast iron pipe is long, the connecting pin in the connecting hole group can be manually separated from the connecting hole group, and then the relative distance between the first connecting sleeve and the second connection can be adjusted until it is suitable for the overall length of the waste cast iron pipe. Then, the connecting pin is inserted into the connecting hole group, and the first connecting sleeve and the second connecting sleeve are fixedly connected. After that, the transport vehicle is driven by the traction equipment to transport the waste cast iron pipe.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-3 The utility model provides a technical solution: a waste cast iron pipe recycling and transportation fixing device, such as Figure 1 As shown, the two sides of the transport vehicle 2 are respectively fixedly connected with the through hole groove block group 1, and the left end of the first connecting sleeve 3 is fixedly connected with the first through hole block group 5. The first through hole block group 5 can be connected to the through hole groove block group 1 at the end of the transport vehicle 2 through a connecting pin, and the first connecting sleeve 3 and the second connecting sleeve 6 can also be connected through the connecting hole group 4 with the connecting pin, and the second connecting sleeve 6 can be connected to the through hole groove block group 1 at the end of the other transport vehicle 2 through the second through hole block group 51 with the connecting pin.
[0019] Then, the first connecting sleeve 3 and the second connecting sleeve 6 can form a relative movement mechanism through the connecting hole group 4 and the connecting pin. When the horizontal length of the waste cast iron pipe is long, the connecting pin can be manually separated from the connecting hole group 4, and then the transport vehicle on the left is towed to move. During the movement of the transport vehicle 2 on the left, the first connecting sleeve 3 and the second connecting sleeve 6 will be driven to move relative to each other, and at the same time, the relative distance between the recessed block groups 701 on the two transport vehicles 2 will be changed, so that the relative distance between the recessed block groups 701 on the two transport vehicles 2 is suitable for the horizontal length of the waste cast iron pipe. After adjusting the relative distance between the recessed block groups 701 on the two transport vehicles, the distance between the first connecting sleeve 3 and the second connecting sleeve 6 is fine-tuned so that the connecting hole groups 4 of the two correspond and the connecting pin is inserted for fixed limit.
[0020] like Figure 3As shown, the adjusting and fixing device 7 is installed above the transport vehicle 2, and the adjusting and fixing device 7 includes a concave block group 701, a threaded rod 702, a through-hole threaded disk 703 and a handle 704. The upper part of the concave block group 701 is fixedly connected to one end of the threaded rod 702, and the concave block group 701 is fixedly connected to the upper part of the transport vehicle 2. At the same time, a through slot is opened through the upper concave block group 701, and the upper concave block group 701 passes through the threaded rod 702 through the through slot and is movably connected to it. , threaded rod 702, through-hole threaded disk 703 and handle bar 704 constitute a rotating lifting mechanism. After the waste cast iron pipe is placed, the upper concave block group 701 is manually passed through the threaded rod 702 so that it is in close contact with the top of the waste cast iron pipe. Then, the through-hole threaded disk 703 is manually rotated and threadedly connected to the threaded rod 702 through the handle bar 704. When the through-hole threaded disk 703 is in close contact with the upper concave block group 701, the rotation of the through-hole threaded disk 703 is stopped.
[0021] There are handle bars 704 fixed on both sides of the through hole threaded disk 703. There are two handle bars 704, and the overall shape of the handle bars 704 is "L" shaped. There are two handle bars 704 through the above-mentioned structural parts, which not only reflects the connection symmetry of the above-mentioned structure, but also reflects the connection practicality and rotational force staggered driving property of the above-mentioned structural parts. Once again, the overall shape of the above-mentioned structural parts is "L" shaped, which facilitates the through hole threaded disk 703 to better apply the rotational torque effect when rotating above another concave block group 701, and the through hole threaded disk 703 is threadedly connected to the threaded rod 702.
[0022] Working principle: When using the waste cast iron pipe recycling and transportation fixing device, first manually separate the connecting pin from the connecting hole group 4, then adjust the relative movement distance between the first connecting sleeve 3 and the second connecting sleeve 6 by the transport vehicle 2, so that the relative distance between the recessed block groups 701 on the two transport vehicles 2 is suitable for the length of the waste cast iron pipe. After the adjustment is completed, connect the connecting pin to the connecting hole group 4 again, and then place the waste cast iron pipe on top of the recessed block group 701 through the lifting equipment. After placement, manually pass the upper recessed block group 701 through the threaded rod 702 to contact the top of the waste cast iron pipe, and then rotate the through-hole threaded disk 703 with the upper recessed block group 701 through the handle 704. When the waste cast iron pipe is fixed, it can be connected to the through-hole groove block group 1 through the traction equipment to drive the overall structural parts to move and transport. This completes the entire operation, and the content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.
