Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, and in particular to a precast concrete equipment for building construction. Background Technology

[0002] In the existing technology, precast concrete components are widely used in the construction of houses, municipal engineering, bridges and tunnels. Precast concrete equipment is mainly used to mix cement, aggregates, admixtures and water, and output the mixture to the precast mold for casting. Currently, existing precast concrete equipment usually includes a fixed frame, mixing container, mixing components and discharge port. However, in actual construction and use, this type of equipment has the following shortcomings: First, the frame structure is mostly integrally welded or fixedly supported, and the installation height is not adjustable, making it difficult to adapt to precast molds of different heights, pouring positions, and uneven construction sites, resulting in poor equipment versatility and inconvenient installation and adjustment; Second, the discharge port mostly adopts a continuously open or manually controlled baffle method, lacking a reliable intermittent opening and closing structure, making it difficult to control the discharge process according to the construction rhythm, which easily leads to unstable discharge volume, material waste, and uneven concrete distribution in the mold; Third, the mixing component usually adopts a single-shaft, single-mixing form, and the material movement trajectory in the mixing container is relatively simple, making it difficult to form multi-directional composite flow of up-and-down tumbling and radial mixing. It is not sufficiently mixed for viscous concrete materials, and it is easy to have mixing dead zones and material segregation, affecting the molding quality of precast components.

[0003] Chinese invention patent application number 202510294086.1 discloses a precast concrete equipment for green building construction, including a workbench with a plate fixedly installed on top. Forming molds are symmetrically arranged inside the plate. An adjustment component is installed on the workbench, and a support frame is also installed. A mixing component is installed inside the support frame, and two support grooves are symmetrically installed inside the support frame. Side plates are symmetrically installed on the support grooves, and a pressure application component is installed inside the support grooves. However, this precast concrete equipment for green building construction has significant shortcomings in terms of frame height adjustment, intermittent discharge control, and mixing effect, making it difficult to meet the requirements of building construction for equipment adaptability, discharge accuracy, and concrete mixing quality.

A precast concrete equipment for building construction includes a mixing hopper 1, with an inlet at the upper end and an outlet at the lower end. It also includes: a frame mechanism located on the upper outer side of the mixing hopper 1, forming an adjustable-height combined frame support; the frame mechanism includes a support frame 2; an opening and closing mechanism assembled at the outlet of the mixing hopper 1, forming an intermittent opening and closing structure; and a mixing mechanism located on the lower inner side of the mixing hopper 1, forming a composite mixing structure. A schematic diagram of the overall structure of this invention is shown below. Figure 1 As shown.

[0019] The mixing hopper 1 is used to contain and mix concrete materials. The inlet is used to feed cement, aggregates, water, or other materials into the mixing hopper 1. The outlet is used to discharge the mixed concrete mixture. The frame mechanism is used to provide height-adjustable modular frame support for the mixing hopper 1 to adapt to different construction positions and mold heights. The opening and closing mechanism is used to control the intermittent opening and closing of the outlet to achieve quantitative and rhythmic discharge. The mixing mechanism is used to perform compound mixing of the materials in the mixing hopper 1 to improve the mixing uniformity. The frame mechanism also includes a frame motor 3, frame eccentric wheels 4, and frame connecting rods 5. There are two sets of frame motors 3, symmetrically arranged on the external mounting frame. There are four sets of frame eccentric wheels 4, with two sets fixedly connected to the output ends of the two sets of frame motors 3, and the other two sets rotatably mounted on the external mounting frame. There are four sets of frame connecting rods 5, with the lower ends of each set hinged to one of the four sets of frame eccentric wheels 4 via bearings. The upper ends of each set of frame connecting rods 5 are connected to the support frame. The frame 2 is hinged, wherein the frame motor 3 drives the frame eccentric wheel 4 to rotate. The frame eccentric wheel 4 converts the rotational motion output by the motor into the lifting motion of the frame connecting rod 5. The frame connecting rod 5 connects the eccentric wheel to the support frame 2 and drives the support frame 2 to swing up and down. The support frame 2 supports the mixing hopper 1 and drives the mixing hopper 1 to swing, thereby shaking the material inside the mixing hopper 1. The symmetrical arrangement of the motor and connecting rod helps to maintain force balance and improve the stability of the frame swing. The schematic diagram of the frame mechanism and the mixing hopper 1 of this invention is shown below. Figure 2 As shown.

[0020] It also includes height adjustment components, of which four sets are arranged in an array between the support frame 2 and the mixing hopper 1. Each height adjustment component includes a height adjustment base 6, height adjustment pads 7, and height adjustment brackets 8. The height adjustment base 6 is fixedly mounted on the upper end of the support frame 2. The height adjustment pads 7 are mounted on the upper end of the height adjustment base 6 and are fixedly connected to the height adjustment base 6 via screws. The height adjustment brackets 8 are fixedly mounted on the upper outer side of the mixing hopper 1. The height adjustment pads 7 are fixedly connected to the height adjustment brackets 8 via screws and nuts. Adjustment is achieved by adjusting the nuts on the screws... The height of the mixing hopper 1 is adjusted by changing the mating position of the height adjustment bracket 8 and the height adjustment pad 7. The height adjustment base 6 is used to fix the height adjustment component to the support frame 2, the height adjustment pad 7 provides height adjustment support, the height adjustment bracket 8 connects the mixing hopper 1 to the height adjustment component, and the screw and nut are used to adjust the relative position of the height adjustment bracket 8 and the height adjustment pad 7, thereby fine-tuning the height of the mixing hopper 1 to adapt to different heights of casting molds and construction sites. A schematic diagram of the engagement between the height adjustment component and the frame mechanism is shown below. Figure 3 As shown.

[0021] The opening and closing mechanism includes opening and closing baffles 9, opening and closing gears 10, and opening and closing hydraulic cylinders 11.

The opening and closing hydraulic cylinder 11 is a double-rod hydraulic cylinder, which is arranged on the outer side of the two sets of opening and closing baffles 9 and its two ends are respectively hinged to the two sets of opening and closing baffles 9. The opening and closing baffles 9 are used to close or open the discharge port. The opening and closing gears 10 are used to make the two sets of opening and closing baffles 9 rotate synchronously in opposite directions to ensure that the discharge port is opened or closed. The opening and closing hydraulic cylinder 11 is used to drive the opening and closing baffles 9 to rotate, thereby providing power for intermittent opening and closing.

[0022] It also includes an opening and closing oil tank 12, an opening and closing hydraulic pump 13, and an opening and closing valve assembly 14. The opening and closing oil tank 12 is fixedly installed on one side of the support frame 2. The opening and closing hydraulic pump 13 is installed at the upper end of the opening and closing oil tank 12 and is connected to the opening and closing oil tank 12. The opening and closing valve assembly 14 is installed on one side of the opening and closing oil tank 12 and is connected to the opening and closing hydraulic pump 13. The opening and closing valve assembly 14 is connected to the opening and closing hydraulic cylinder 11 through a pipeline. The opening and closing oil tank 12 is used to store hydraulic oil, the opening and closing hydraulic pump 13 is used to supply pressurized oil to the opening and closing hydraulic cylinder 11, and the opening and closing valve assembly 14 is used to control the opening and closing of the oil circuit and the reversal, so that the opening and closing hydraulic cylinder 11 operates according to a set rhythm to realize the intermittent opening and closing of the discharge port.

[0023] The mixing mechanism includes a mixing motor 15, a mixing mounting shaft 16, mixing support rods 17, and a mixing I-beam frame 18. The mixing motor 15 is fixedly installed on one side of the lower part of the mixing hopper 1. The mixing mounting shaft 16 is installed on the lower inner side of the mixing hopper 1, corresponding to the mixing motor 15, and is rotatably connected to the mixing hopper 1. The output end of the mixing motor 15 passes through the mixing hopper 1 and is drively connected to one end of the mixing mounting shaft 16. Several sets of mixing support rods 17 are provided, and the several sets of mixing support rods 17 are arranged circumferentially around the middle outer side of the mixing mounting shaft 16 and are fixedly connected to the mixing mounting shaft 16. Two sets of mixing I-beam frames 18 are provided, staggered at both ends of the mixing mounting shaft 16 and fixedly connected to it. The mixing motor 15 provides mixing power, the mixing mounting shaft 16 transmits power and supports the mixing components, the mixing support rod 17 radially agitates the material in the middle of the mixing hopper 1, and the mixing I-beam frames 18 perform axial and radial combined mixing of the material at both ends of the mixing hopper 1, causing the material to tumble and mix radially to improve the mixing effect and reduce dead zones. A cross-sectional view of the mixing mechanism and the mixing hopper 1 is shown below. Figure 4 As shown.

[0024] The system also includes a toggle assembly, which comprises a toggle motor 19, a toggle base plate 20, and a toggle arc frame 21. The toggle motor 19 is fixedly disposed on the lower outer side of the mixing hopper 1, and the toggle base plate 20 is disposed on the lower inner side of the mixing hopper 1 corresponding to the toggle motor 19. The output end of the toggle motor 19 passes through the mixing hopper 1 and is connected to the toggle base plate 20 for transmission. The toggle arc frame 21 is fixedly disposed on the lower part of the toggle base plate 20 and arranged at the discharge port of the mixing hopper 1. The toggle motor 19 is used to provide toggle power, and the toggle base plate 20 is used to connect the motor output end and drive the toggle arc frame 21 to move. The toggle arc frame 21 is used to reciprocate toggle the material at the discharge port to prevent blockage of the discharge port and promote uniform discharge of the material. A schematic diagram of the toggle assembly and the mixing hopper 1 is shown below. Figure 5 As shown.

[0025] It also includes a baffle plate 22, which is fixedly installed on the lower inner side of the mixing hopper 1 and fixedly connected to the mixing hopper 1, corresponding to the actuating component. The baffle plate 22 has a pointed plate structure. The baffle plate 22 is used to divert and disturb the stirring and falling materials to enhance the local turbulence near the discharge port, prevent material segregation and arching, and help improve the uniformity of discharge.

[0026] The system also includes a timer 23 and an electrical control unit 24. The timer 23 is fixedly mounted on one side of the support frame 2. The electrical control unit 24 is adjacent to the timer 23 and fixed to the support frame 2. The electrical control unit 24 is electrically connected to the frame motor 3, the hydraulic pump 13, the stirring motor 15, the agitator motor 19, and the timer 23. The timer 23 provides a timing signal to set the stirring time and the discharge interval. The electrical control unit 24 receives the timing signal and controls the working status of the frame motor 3, the hydraulic pump 13, the stirring motor 15, and the agitator motor 19, thereby achieving automatic control of equipment operation and intermittent discharge. A schematic diagram of the electrical control unit 24 and the timer 23 in conjunction with the mixing hopper 1 is shown below. Figure 6 As shown.

[0027] The mixing hopper 1 is configured with a frustum-shaped structure, which is wider at the top and narrower at the bottom. This facilitates the material's convergence towards the discharge port under gravity, reducing dead zones and promoting efficient discharge and cleaning. A schematic diagram of the mixing hopper 1 and the actuating motor 19 is shown below. Figure 7 As shown.

[0028] Working principle: When using this equipment, the height of the mixing hopper 1 is first finely adjusted using the screw and nut in the height adjustment component to adapt the equipment to the construction position and mold height. After the material is fed into the mixing hopper 1 through the inlet, the frame motor 3 drives the frame eccentric wheel 4 and frame connecting rod 5 to move, which in turn drives the mixing hopper 1 to swing through the support frame 2. At the same time, the stirring motor 15 is started, and the stirring mounting shaft 16 drives the stirring support rod 17 and the stirring I-beam frame 18 to rotate, performing radial and axial compound stirring of the material. Simultaneously, the motor is turned... 19 drives the agitator frame 21 to reciprocate near the discharge port. The baffle plate 22 diverts and disturbs the material to prevent blockage and segregation near the discharge port. During discharge, the electrical control unit 24 controls the opening and closing of the hydraulic pump 13 and the valve group 14 according to the rhythm set by the timer 23. This causes the hydraulic cylinder 11 to drive the two sets of opening and closing baffles 9 to open or close synchronously under the action of meshing gears, realizing intermittent discharge of concrete mixture. The mixing and discharge process can be carried out in a cycle according to the rhythm until the precast pouring operation is completed.

[0029] The beneficial effects of this invention are: it features a modular frame structure that provides height-adjustable installation support for the prefabrication mechanism, adapting to different construction positions and mold heights; it includes a prefabrication mechanism with an intermittent opening and closing structure at the discharge port, allowing for intermittent discharge, ensuring controllable discharge volume, uniform material distribution, and reduced material waste; it also includes a mixing mechanism that performs compound mixing of materials in the prefabrication mechanism, resulting in good mixing effect, reduced mixing dead zones, and improved quality of precast concrete components; the overall structure is compact and highly automated, effectively improving construction efficiency and quality.
