Description

Technical Field

[0001] This utility model relates to the technical field of precast component demolding, and in particular to a precast foundation pier demolding device. Background Technology

[0002] The demolding process of precast concrete components is a crucial step in precast component production, directly affecting the product's appearance quality, structural integrity, and subsequent performance. Large components require the use of cranes, jacks, and other equipment to assist in demolding, preventing damage due to their own weight or stress concentration. Demolding should be slow and smooth, avoiding violent pulling or knocking to prevent damage to the component's edges and corners. Precast foundation piers are foundation components prefabricated in a factory or specific site, then transported to the construction site for installation, offering numerous advantages and application scenarios.

[0003] The existing Chinese utility model patent with application number CN201922134073.0 relates to a preform demolding device, which includes a frame, transmission box, protective shell, lifting screw, rotating motor and transmission belt, etc., which can achieve high efficiency in demolding and increase demolding efficiency.

[0004] However, the above-mentioned device is not suitable for the demolding process of medium and large concrete foundation piers in actual use. During the demolding process of concrete piers, the mold and the component may stick together. It is necessary to ensure that the mold and the component rise horizontally when they separate to reduce collision damage between the mold and the component. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a precast foundation pier demolding device that collects and discharges curing water and debris during the component prefabrication process through a sewage discharge device, lifts the mold horizontally and steadily through a demolding device to complete the initial separation between the mold and the component, reducing collision damage between the mold and the component, and completes the lifting of the mold and the separation of the component through a drive device, thereby improving the practicality of the device.

[0006] This utility model discloses a precast foundation pier demolding device, comprising a sewage discharge device, a demolding device, and a driving device. The demolding device is installed on the sewage discharge device, and the driving device is installed on the sewage discharge device. The sewage discharge device collects and discharges curing water and debris during the component prefabrication process. The demolding device lifts the mold horizontally and smoothly, completing the initial separation between the mold and the component, reducing collision damage between the mold and the component. The driving device completes the lifting of the mold and the complete separation from the component, improving the practicality of the device.

[0007] Preferably, the sewage discharge device includes a base, a support platform, a sloping bottom, a sewage discharge trough, and a guide pipe. A set of rectangular grooves is provided on the left and right sides of the upper end face of the base. A support platform is provided in the middle of the upper end face of the base. A sloping bottom is provided at the bottom of the rectangular grooves. The two sets of sloping bottoms slope downwards on the side closest to the support platform, and a sewage discharge trough is provided at the lowest part of the sloping bottom. Two sets of guide pipes are provided on the side of the base and connected to the two sets of sewage discharge troughs respectively. The maintenance water is discharged from the equipment through the sewage discharge trough and guide pipes. The sloping bottom causes dust and sewage in the rectangular grooves on the base to collect in the sewage discharge trough. The base provides support for the components, improving the practicality of the device.

[0008] Preferably, the device also includes helical blades and geared motors. Two sets of geared motors are installed on the side of the base, and a set of helical blades are horizontally installed in each of the two sets of sewage discharge tanks. The output ends of the two sets of geared motors are connected to the two sets of helical blades respectively. When the geared motors are turned on, the power is transmitted to the helical blades to drive them to rotate. The rotating helical blades discharge solid waste from the sewage discharge tanks into the device, which improves the practicality of the device.

[0009] Preferably, the demolding device includes hydraulic cylinders, demolding support platforms, connecting blocks, and limiting rods. Two sets of hydraulic cylinders are installed in the two sets of rectangular slots of the base, one in the front and one in the back. Two sets of demolding support platforms are located inside the two sets of rectangular slots, and the moving ends of the hydraulic cylinders are connected to the lower end faces of the demolding support platforms. Multiple sets of rectangular holes are provided at the lower part of the support platforms, connecting to the rectangular slots on both sides of the support platforms. Multiple sets of connecting blocks are located in the multiple sets of rectangular holes, and the left and right parts of the connecting blocks are connected to the lower end faces of the demolding support platforms in the rectangular slots on both sides, respectively. Vertical limiting rods are provided in the rectangular holes, and the limiting rods pass through the connecting blocks. The main body of the device has its upper surface of the demolding support platform tilted downwards on the side closest to the support platform. By controlling the extension and retraction of the hydraulic cylinder, the demolding support platform moves up and down, lifting the mold on the component and initially separating the mold from the component. The lifting process of the demolding support platform is limited by the connecting block and the limiting light rod, so that the two sets of demolding support platforms remain stable during the lifting and lowering process, preventing uneven force on the mold and tilting during demolding, which could cause the component to collide. The tilting of the upper surface of the demolding support platform can accommodate molds of different sizes and prevent the demolding support platform from directly contacting the component, thus improving the practicality of the device.

[0010] Preferably, the device also includes vibration motors and pressure sensors. Multiple sets of vibration motors are installed on the lower end face of the demolding support platform. The moving end of the hydraulic cylinder is connected to the lower end face of the demolding support platform through a pressure sensor. During the initial demolding, multiple sets of vibration motors are activated to drive the demolding support platform to vibrate slightly, thereby accelerating the separation rate between the mold and the component. The pressure sensor monitors the pressure on the moving end of the multiple sets of hydraulic cylinders to prevent excessive pressure in a single set from causing the demolding support platform to tilt, thus improving the practicality of the device.

[0011] Preferably, the drive device includes a gantry, a take-up roller, and a drive motor. The gantry is mounted on the upper surface of the base, and the take-up roller is mounted on the upper surface of the gantry via a bracket. The drive motor is mounted on the side of the bracket, and the output end of the drive motor is connected to the take-up roller. A steel wire rope is wound on the take-up roller. When the drive motor is turned on, power is transmitted to the take-up roller to drive it to rotate, thereby completing the winding and unwinding of the steel wire rope. This facilitates the hoisting and separation of the mold and improves the practicality of the device.

[0012] Preferably, the device also includes a connecting seat, lifting connection holes, and a level. The connecting seat is connected to the end of the wire rope of the winding roller. Four sets of lifting connection holes are evenly distributed on the lower part of the connecting seat. A level is installed on the connecting seat. The connecting seat and the four sets of lifting connection holes facilitate the connection between the wire rope and the four corners of the mold, thereby keeping the mold in a horizontal state during the complete separation of the mold from the component and reducing the shaking of the mold itself. The level of the connecting seat is monitored by the level, which improves the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the sewage discharge device collects and discharges the curing water and debris during the component prefabrication process; the demolding device lifts the mold horizontally and steadily to complete the initial separation between the mold and the component, reducing the collision damage between the mold and the component; and the driving device completes the lifting of the mold and the complete separation of the component, thus improving the practicality of the device.
