Description

Technical Field

[0001] This utility model belongs to the field of pipe pile production technology, specifically relating to a new type of pipe pile casting mold and its support frame. Background Technology

[0002] PHC pipe piles, or prestressed high-strength concrete pipe piles, are hollow cylindrical precast concrete components produced using a pre-tensioned prestressed centrifugal molding process. They are formed in a mold and cured with steam at approximately 10 atmospheres (1.0 MPa) and 180°C. Currently, the molds used for producing concrete pipe piles typically consist of a hollow semi-circular upper and lower mold. A crane places the lower mold on a special support, concrete is poured into it, and then the upper mold is placed on top. The upper and lower molds are connected by bolts to complete the mold assembly. Because the lower mold has a limited capacity, an excess of concrete is needed to completely fill it. The concrete, with its high slump, maintains a certain height within the lower mold before the upper mold is accurately placed on top. Due to the high noise and vibration in the production workshop, the concrete in the lower mold often falls out, and hoisting workers are also prone to touching the concrete in the lower mold when hoisting the upper mold. Therefore, throughout the entire operation, workers need to continuously replenish concrete around the lower formwork and coordinate with the workers hoisting the upper formwork. This places high demands on the technical proficiency and teamwork of the operators, and also poses a severe challenge to production safety and quality. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1-3 As shown, a novel pipe pile casting mold includes a lower mold 1 and an upper mold. The upper mold consists 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 several bolts 4. Several lifting lugs 5 are provided on both sides of the lower mold 1. By unscrewing the bolts 4, the left half mold 2 and the right half mold 3 are opened to the lower mold 1 at a certain angle, and concrete is poured into the lower mold. Then, the left half mold 2 and the right half mold 3 are closed, and the bolts 4 are tightened to complete the mold closing. The upper mold is not required to be hoisted. The left half mold 2 and the right half mold 3, which open at a certain angle, can prevent a large amount of concrete from scattering when pouring concrete into the lower mold, saving materials and labor.

[0017] Furthermore, the left side of the lower mold 1 is connected to the left half mold 2 via a left hinge mechanism, and the right side of the lower mold 1 is connected to the right half mold 3 via a right hinge mechanism. The left and right hinge mechanisms have the same structure. The left hinge mechanism includes a rotating shaft 6, several upper mounting blocks 7, and several lower mounting blocks 8. The upper mounting blocks 7 and lower mounting blocks 8 are arranged alternately. The upper mounting blocks 7 are fixed to the left half mold 2, and the lower mounting blocks 8 are fixed to the lower mold 1. The rotating shaft 6 rotatably passes through all the upper mounting blocks 7 and lower mounting blocks 8. The upper mounting blocks 7 and 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 the two ends of the rotating shaft 6 are respectively provided with limiting nuts. When closing the mold, the concrete at the left and right hinge mechanisms needs to be cleaned manually.

[0018] Furthermore, the left half mold 2 and the right half mold 3 are respectively provided with several through holes, and the through holes on the left half mold 2 and the through holes on the right half mold 3 correspond one-to-one. The bolt 4 passes through the through holes on the left half mold 2 and the corresponding through holes on the right half mold 3 respectively and is connected to a nut.

[0019] Furthermore, the lifting lugs 5 on both sides of the lower mold 1 are located below the left hinge mechanism and the right hinge mechanism, respectively.

[0020] A support frame for a pipe pile casting mold includes a frame body 9 and an arc-shaped support groove 10 on the frame body 9, the arc-shaped support groove 10 matching the lower mold 1. The pipe pile casting mold is placed within the arc-shaped support groove 10 on the frame body 9 to maintain its stability. When the pipe pile casting mold is placed within the arc-shaped support groove 10, lifting lugs 5 on both sides protrude from the arc-shaped support groove 10 for lifting by cranes or other means. Because the distance between the lifting lugs 5 and the sides of the arc-shaped support groove 10 is relatively short, support points 11 can be set on both sides of the arc-shaped support groove 10. By applying tools such as crowbars to the support points 11 and the lifting lugs 5, the posture of the pipe pile casting mold can be adjusted.

[0021] Furthermore, the arc-shaped support groove 10 has several evenly spaced support rods 12 on both sides. The upper end of each support rod 12 has an arc-shaped support portion that matches the circumferential surface of the left half mold 2 or the right half mold 3. The support rods 12 are fixed to the frame 9. When the left half mold 2 and the right half mold 3 are opened, the support rods 12 maintain a certain opening angle between them. When closing the mold, a 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, reducing the force on the rotating shaft 6 and avoiding the deformation caused by the weight 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 over for a long time. The left half mold 2 and the right half mold 3 are in a flared state, which increases the receiving area, reduces concrete material falling, and improves material utilization.

[0022] It is worth mentioning that the technical features such as the crane involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of the crane hoisting pipe pile casting mold can adopt conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not be further elaborated in detail.

[0023] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
