At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.
[0021] See also Figure 1-2 The utility model provides a retractable material guide for PCCP pipe core casting, including a metal steel pipe 4 and an umbrella-shaped material guide surface 2 hinged to the top of the metal steel pipe 4 and capable of opening and closing. The umbrella-shaped material guide surface 2 is driven to open and close by a driving component. The upper end of the umbrella-shaped material guide surface 2 is hinged to the top of the metal steel pipe 4, and a material ejection needle 1 is connected to the outer wall of the upper end of the umbrella-shaped material guide surface 2.
[0022] When this embodiment is used, when preparing to cast the concrete of the PCCP pipe core, the driving assembly drives the umbrella-shaped guide surface 2 to rotate around the top of the metal steel pipe 4 to open and close, and adjusts the size of the umbrella-shaped guide surface 2 to the size required for casting. Then, the conical guide is hoisted above the assembled mold by the gantry crane, and the guide is vertically covered on the mold. The ejector needle 1 lifts the hopper door, and the poured concrete enters the concrete casting surface through the umbrella-shaped guide surface 2 to complete the core casting work. After the casting is completed, clean it from the top with clean water to prevent the concrete from solidifying and affecting the next use. When not in use, the umbrella-shaped guide surface 2 can be folded up.
[0023] Therefore, this embodiment can realize that one material guide can guide the pouring of concrete for PCCP pipes of different diameters, effectively avoiding idle material guides occupying a large amount of production space.
[0024] As a further description of the above embodiment, the umbrella-shaped material guide surface 2 includes a plurality of conical material guide blocks 21 connected in sequence, any two adjacent conical material guide blocks 21 are connected by four metal hinges 5, and the conical end of the conical material guide block 21 is hinged to the top end of the metal steel pipe 4.
[0025] When this embodiment is used, when the size of the umbrella-shaped material guide surface 2 needs to be adjusted, the driving component drives several conical material guide blocks 21 to move outward or inward at the same time. During the movement, the top of the conical material guide block 21 rotates around the hinge point with the metal steel pipe 4. At the same time, the two adjacent conical material guide blocks 21 are connected by the metal hinge 5 to achieve rotation, thereby realizing the separation or merging of the two adjacent conical material guide blocks 21, thereby realizing the opening and closing of the umbrella-shaped material guide surface 2, meeting the guidance of concrete pouring of PCCP pipes with different diameters.
[0026] In this embodiment, the connection method between two adjacent conical guide blocks 21 is not limited to the metal hinge 5 connection, and other connection methods that can achieve rotatable connection between two adjacent conical guide blocks 21 are also possible, such as hinge connection.
[0027] In this embodiment, two adjacent conical guide blocks 21 are not limited to being connected by four metal hinges 5 , and the number of corresponding metal hinges 5 , such as 3, 5, etc., can be selected according to actual working conditions.
[0028] As a further description of the above embodiment, the bottom of each of the conical guide blocks 21 is configured as a triangular tip 22 .
[0029] When this embodiment is used, the triangular tip 22 is provided at the bottom of the conical guide block 21 to prevent concrete from flowing to the bottom of the conical guide block 21 during the pouring process, thereby avoiding the concrete from being retained and agglomerated, which increases the difficulty of cleaning.
[0030] As a further description of the above embodiment, the driving assembly includes a plurality of cylinders 3 and a telescopic shaft 6 connected to the output end of the cylinder 3, the cylinder 3 is fixed on a metal steel pipe 4, and the end of the telescopic shaft 6 is hinged to the inner wall of the conical guide block 21.
[0031] When this embodiment is used, when the umbrella-shaped material guiding surface 2 needs to be opened and closed, several oil cylinders 3 are started at the same time. The oil cylinders 3 drive the telescopic shaft 6 to extend or shorten. During the extension or shortening of the telescopic shaft 6, the conical material guiding block 21 hinged thereto is driven to rotate outward or inward around the top of the metal steel pipe 4, thereby realizing the opening and closing of the umbrella-shaped material guiding surface 2 to meet different usage requirements.
[0032] As a further description of the above embodiment, the ejection needle 1 includes a cylindrical connecting end 11 and a conical ejection end 12, the connecting end 11 and the ejection end 12 are integrally formed, and the bottom of the connecting end 11 is hinged to the outer surface of the conical guide block 21.
[0033] When the present embodiment is used, the ejector pin 1 is hinged to the outer surface of the conical guide block 21 through the connection end 11 to ensure that the conical guide block 21 can be opened and closed normally, thereby avoiding a fixed connection that restricts the movement of the conical guide block 21 .
[0034] As a further description of the above embodiment, a hanging hole 7 is opened in the middle of the top material end 12. The center of the hanging hole 7 is in the same straight line with the vertical center of the metal steel pipe 4.
[0035] When the present embodiment is used, the provision of the lifting hole 7 facilitates the gantry crane to lift the material guide to the top of the assembled mold through the lifting hole 7 .
[0036] In this embodiment, the center of the lifting hole 7 and the vertical center of the metal steel pipe 4 are in the same straight line to ensure the stability of the material guide during lifting and prevent the material guide from deflecting during lifting, thereby increasing the difficulty of manual adjustment by the staff.
[0037] In summary, the working principle of the retractable material guide for PCCP core casting is as follows:
[0038] When preparing to cast the concrete of the PCCP pipe core, the telescopic shaft 6 is extended or shortened by the oil cylinder 3, thereby driving the conical guide block 21 to rotate, and then adjusting the diameter of the umbrella-shaped guide surface 2 to the size corresponding to the diameter of the pipe to be produced; then, the guide is lifted to the top of the assembled mold through the lifting hole 7 in the lifting needle 1 by the gantry crane, and the guide is vertically covered on the mold. The lifting needle 1 lifts the hopper door, and the poured concrete enters the concrete casting surface through the conical guide surface to complete the pipe core casting task. After the casting is completed, the guide is cleaned with clean water and put away for the next use.
[0039] In summary, the utility model has a simple structure, is easy to install, can change the size to meet the concrete guiding work when pouring pipes of different diameters, occupies a small area when idle, and has low production and use costs. Therefore, the utility model effectively overcomes various shortcomings of the prior art and has a high industrial utilization value.
