Description

Technical Field

[0001] This utility model relates to the field of prestressed square pile production technology, specifically a quick-change structure for prestressed square pile molds. Background Technology

[0002] Prestressed square piles are precast concrete square piles that embody the advancements in modern concrete technology and the high level of advanced concrete product manufacturing processes. Prestressed square piles can be classified into various types according to different production processes and applications, such as solid prestressed concrete square piles and hollow prestressed concrete square piles. The main functions of prestressed square piles include:

[0003] Load and Reinforcement: Prestressed square piles are suitable for industrial and civil buildings. As high-strength concrete square piles, they can provide support and reinforcement, effectively transferring the load of the superstructure to the foundation, ensuring the stability and safety of the building. Improved Construction Efficiency: The prefabrication characteristics of prestressed square piles make it easy to ensure manufacturing quality and facilitate mechanized construction. Adaptability to Various Geological Conditions: Prestressed square piles have strong geological adaptability, suitable for various engineering needs from multi-story to high-rise buildings, especially in areas with complex geological conditions and large variations in the bearing stratum. Seismic and Crack Resistance: Some prestressed square piles, such as threaded prestressed square piles, have excellent seismic, bending, shear, and tensile properties, making them suitable for areas with high seismic fortification intensity and environmental categories I and II. Material and Cost Savings: Prestressed square piles reduce the self-weight of components and improve tensile performance through prestressing technology, while reducing material usage and lowering costs. Compared to pipe piles, square piles have a relatively smaller volume for the same lateral area, thus saving more material while maintaining the same performance.

[0004] However, in practical applications of existing technologies, mold replacement is a common operation in the production process of prestressed square piles. Traditional methods for replacing prestressed square pile molds typically require disassembling the entire mold from the production line and then installing a new mold. This process involves a large amount of bolt removal and installation, mold positioning and adjustment, etc., which is not only cumbersome but also time-consuming. Utility Model Content

[0005] The purpose of this invention is to provide a quick-change structure for prestressed square pile molds, addressing the issue raised in the background section that mold replacement is a common operation in the production process of prestressed square piles. Traditional methods for changing prestressed square pile molds typically require disassembling the entire mold from the production line and then installing a new mold. This process involves numerous bolt removals and installations, mold positioning and adjustments, etc., which is not only cumbersome but also time-consuming.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a mold body and a mounting base, wherein a mounting base plate is fixedly installed at the bottom of the mold body, and lifting rings for hoisting the mounting base plate are fixedly installed at the four corners of the mounting base plate;

[0007] Positioning pins are fixedly installed on both sides of the upper end of the mounting base, and extension platforms are fixedly installed on both sides of the lower end of the mounting base. A swing frame is rotatably connected to the outer side of the extension platform via a pin shaft. A support column is fixedly installed on the inner side of the lower end of the swing frame. A first electric telescopic rod is rotatably connected to the outer wall of the mounting base via a pin shaft. A second electric telescopic rod is fixedly installed through the inner side of the upper end of the swing frame. An L-shaped extrusion plate is fixedly installed on the telescopic part of the lower end of the second electric telescopic rod. Limiting slide rods are fixedly installed on both sides of the upper end of the L-shaped extrusion plate. An anti-slip pad is adhered to the inner side of the L-shaped extrusion plate.

[0008] Preferably, the mounting base plate has a number of positioning holes through both sides, which are symmetrically distributed on both sides of the mounting base plate.

[0009] Preferably, a power control cabinet is fixedly installed on the side of the mounting base, and the positioning pin is movably connected to the inner wall of the positioning hole.

[0010] Preferably, there are two extension platforms, which are symmetrically distributed on both sides of the lower end of the mounting base.

[0011] Preferably, the outer side of the first electric telescopic rod is inclined downward, and the telescopic part of the outer side of the first electric telescopic rod is rotatably connected to the outer curved surface of the middle part of the support column via a rotating shaft.

[0012] Preferably, a U-shaped limiting frame is fixedly installed on the outer wall of the mounting base, and the inner sides of both ends of the swing frame are movably connected to the inner wall of the outer side of the U-shaped limiting frame.

[0013] Preferably, the upper end of the limiting slide bar is movably connected to the inner side of the upper end of the swing frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the clamping and fixing of the mounting base plate is released, the first electric telescopic rod is extended by control. When the first electric telescopic rod extends, it drives the swing frame to swing outward through the support column. When the swing frame swings outward, the mounting base plate is lifted upward by the lifting ring and hoisting equipment. When the mounting base plate is lifted upward, the mold body can be lifted and disassembled. When the mold body needs to be replaced, the mounting base plate is lifted to the upper end of the mounting base by the lifting ring, so that the positioning pin is aligned with the positioning hole. When the positioning pin is aligned with the positioning hole, the mounting base plate is lowered, so that the mounting base plate is installed and positioned at the upper end of the mounting base. When the mounting base plate is positioned at the upper end of the mounting base, the first electric telescopic rod is retracted by control. When the first electric telescopic rod retracts, it drives the swing frame to swing inward. When the swing frame swings inward, the second electric telescopic rod is extended downward by control. When the second electric telescopic rod extends downward, it drives the L-shaped pressing plate and the anti-slip pad to press and fix the mounting base plate downward, thereby facilitating the replacement of the mold body.

Extension platforms 8 are fixedly installed on both sides of the lower end of the mounting base 2, and there are two extension platforms 8, symmetrically distributed on both sides of the lower end of the mounting base 2. A swing frame 9 is rotatably connected to the outer side of the extension platform 8 via a pin. A support column 10 is fixedly installed on the inner side of the lower end of the swing frame 9. A first electric telescopic rod 11 is rotatably connected to the outer wall of the mounting base 2 via a pin. The outer side of the first electric telescopic rod 11 is inclined downwards, and the telescopic part of the outer side of the first electric telescopic rod 11 is connected by a pivot. A U-shaped limiting frame 12 is fixedly installed on the outer curved surface of the middle part of the support column 10 and the outer wall of the mounting base 2. The inner sides of both ends of the swing frame 9 are movably connected to the outer inner wall of the U-shaped limiting frame 12, so that the swing frame 9 is supported and limited by the U-shaped limiting frame 12.
