Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of pipe pile production, and particularly relates to a new type of pipe pile casting mold and its support frame. Background Art
[0002] PHC pipe piles are prestressed high-strength concrete pipe piles. They are formed by a pre-tensioned centrifugal forming process in a forming mold and cured by steam at about 10 atmospheres (about 1.0 Mpa) and about 180 °C to produce a hollow cylindrical concrete precast member. Currently, the molds used in the production of concrete pipe piles are usually composed of an upper mold and a lower mold that are semi-circular and hollow. The lower mold is placed on a special support by a crane, concrete is loaded into the lower mold, and then the upper mold is covered on the lower mold. The upper mold and the lower mold are connected by several bolts to complete the mold closing. Since the loading capacity of the lower mold is limited, to completely fill the mold, an excessive amount of concrete needs to be loaded into the lower mold. The concrete relies on its relatively large slump to maintain a certain height in the lower mold, and then the upper mold is accurately covered on the lower mold. Due to the high noise and vibration in the production workshop, the concrete fully loaded in the lower mold often falls, and the hoisting worker is also prone to touching the concrete in the lower mold when hoisting the upper mold. Therefore, during the entire operation process, workers need to continuously supplement concrete around the lower mold and cooperate with the upper mold hoisting workers. This poses relatively high requirements for the technical proficiency and cooperation of the operating workers, and also poses severe challenges to the safety and quality issues of production. Summary of the Invention
[0003] To solve the above technical problems, the technical solution adopted by the present invention is: a new type of pipe pile casting mold, including a lower mold and an upper mold. The upper mold is composed of a left half mold and a right half mold. The left half mold is hinged to one side of the lower mold, and the right half mold is hinged to the other side of the lower mold. The left half mold and the right half mold are detachably connected by several bolts. Several lifting lugs are respectively arranged on both sides of the lower mold.
[0004] As a preference of the above technical solution, the left side of the lower mold is connected to the left half mold through a left hinge mechanism, and the right side of the lower mold is connected to the right half mold through a right hinge mechanism. The left hinge mechanism and the right hinge mechanism have the same structure. The left hinge mechanism includes a rotating shaft, several upper mounting blocks, and several lower mounting blocks. The upper mounting blocks and the lower mounting blocks are arranged alternately in sequence. The upper mounting blocks are fixed on the left half mold, and the lower mounting blocks are fixed on the lower mold. The rotating shaft sequentially passes through all the upper mounting blocks and the lower mounting blocks rotatably. Mounting holes for the rotating shaft to pass through are respectively arranged on the upper mounting blocks and the lower mounting blocks. The length direction of the rotating shaft is parallel to the length direction of the casting mold, and limit nuts are respectively arranged at both ends of the rotating shaft.

[0006] Preferably, as the above technical solution, the lifting lugs on both sides of the lower mold are respectively located below the left hinge mechanism and the right hinge mechanism.
[0007] A support frame of a pipe pile casting mold includes a frame body and an arc-shaped support groove provided on the frame body, and the arc-shaped support groove is matched with the lower mold.
[0008] Preferably, as the above technical solution, a plurality of support rods are respectively provided on both sides of the arc-shaped support groove at uniformly spaced intervals, arc-shaped supporting parts matched with the circumferential surfaces of the left half mold or the right half mold are respectively provided at the upper ends of the support rods, and the support rods are fixed on the frame body.
[0009] The beneficial effects of the present invention are as follows: For the pipe pile casting mold and its support frame of the present invention, the mold closing is fast and simple.

[0013] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0014] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes, and cannot be construed as indicating or implying relative importance.
[0015] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0016] As Figures 1-3 shown, a new type of pipe pile casting mold includes a lower mold 1 and an upper mold. The upper mold is composed of a left half mold 2 and a right half mold 3. The left half mold 2 is hinged to one side of the lower mold 1, and the right half mold 3 is hinged to the other side of the lower mold 1. The left half mold 2 and the right half mold 3 are detachably connected by a plurality of bolts 4. A plurality of lifting lugs 5 are respectively arranged on both sides of the lower mold 1. Unscrew the bolts 4, open the left half mold 2 and the right half mold 3 downward relative to the lower mold 1 at a certain angle, pour the concrete into the lower mold, then close the left half mold 2 and the right half mold 3, and screw on the bolts 4 to complete the mold closing. There is no need to hoist the upper mold. The left half mold 2 and the right half mold 3 that are opened at a certain angle can prevent a large amount of concrete from scattering when the lower mold is filled with concrete, saving raw materials and labor.
[0017] Furthermore, the left side of the lower mold 1 is connected to the left half mold 2 through a left hinge mechanism, and the right side of the lower mold 1 is connected to the right half mold 3 through a right hinge mechanism. The left hinge mechanism and the right hinge mechanism have the same structure. The left hinge mechanism includes a rotating shaft 6, a plurality of upper mounting blocks 7, and a plurality of lower mounting blocks 8. The upper mounting blocks 7 and the lower mounting blocks 8 are arranged alternately in sequence. The upper mounting blocks 7 are fixed on the left half mold 2, and the lower mounting blocks 8 are fixed on the lower mold 1. The rotating shaft 6 sequentially passes through all the upper mounting blocks 7 and the lower mounting blocks 8 in a rotatable manner. The upper mounting blocks 7 and the lower mounting blocks 8 are respectively provided with mounting holes for the rotating shaft 6 to pass through. The length direction of the rotating shaft 6 is parallel to the length direction of the casting mold, and limiting nuts are respectively arranged at both ends of the rotating shaft 6. When closing the mold, it is necessary to manually clean the concrete at the left hinge mechanism and the right hinge mechanism.
[0018] Furthermore, a plurality of through holes are respectively arranged on the left half mold 2 and the right half mold 3. The through holes on the left half mold 2 and the through holes on the right half mold 3 correspond one by one. The bolts 4 respectively pass through the through holes on the left half mold 2 and the corresponding through holes on the right half mold 3 and are connected with nuts.
[0019] Furthermore, the lifting lugs 5 on both sides of the lower mold 1 are respectively located below the left hinge mechanism and the right hinge mechanism.
[0020] A support frame for a pipe pile casting mold, comprising a frame body 9 and an arc-shaped supporting groove 10 provided on the frame body 9, and the arc-shaped supporting groove 10 is matched with the lower mold 1. Place the pipe pile casting mold in the arc-shaped supporting groove 10 on the frame body 9 to maintain the stability of the pipe pile casting mold. When the pipe pile casting mold is placed in the arc-shaped supporting groove 10, the lifting lugs 5 on both sides protrude from the arc-shaped supporting groove 10 for hoisting by a traveling crane or the like. Since the distance between the lifting lugs 5 and both sides of the arc-shaped supporting groove 10 is short, support points 11 can be provided on both sides of the arc-shaped supporting groove 10, and tools such as crowbars are applied to the support points 11 and the lifting lugs 5 to adjust the posture of the pipe pile casting mold.
[0021] Furthermore, a number of uniformly spaced support rods 12 are respectively provided on both sides of the arc-shaped supporting groove 10, and arc-shaped supporting parts matched with the circumferential surfaces of the left half mold 2 or the right half mold 3 are respectively provided at the upper ends of the support rods 12, and the support rods 12 are fixed on the frame body 9. Open the left half mold 2 and the right half mold 3, and the support rods 12 keep the left half mold 2 and the right half mold 3 at a certain opening angle. When closing the mold, a relatively small force tool can be used to push the left half mold 2 and the right half mold 3 to complete the mold closing. The support rods 12 bear part of the weight of the left half mold 2 or the right half mold 3, reduce the stress on the rotating shaft 6, and avoid deformation and other influences caused by the long-term gravity of the left half mold 2 or the right half mold 3 and the huge impact force generated when the left half mold 2 or the right half mold 3 is flipped. The left half mold 2 and the right half mold 3 are in a flared state, expanding the material receiving area, reducing the dropping of concrete materials, and improving the material utilization rate.
[0022] It is worth mentioning that the technical features such as the traveling crane involved in this invention patent application should be regarded as the prior art. The traveling crane hoists the pipe pile casting mold. The specific structure, working principle, possible control methods, and spatial layout methods of these technical features can be selected conventionally in this field, and should not be regarded as the invention points of this invention patent. This invention patent will not be further specifically elaborated.
[0023] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
