Description

Technical Field

[0001] This utility model belongs to the field of intelligent construction technology of concrete components, specifically relating to a walking compression casting and molding machine for concrete curb stones. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] With the stable development of society and economy, highway construction has also developed rapidly. Among them, precast concrete components are an indispensable part of highway engineering, and related construction technology is also moving towards intelligentization. However, the processes of handling, installing, and aligning concrete components still require manual adjustment, which wastes a lot of manpower and even threatens personal safety.

[0004] Curbstones are marker stones placed between the road surface and other structures. As the most common structure on urban roads, they are often used between the median strip and the road surface, between the sidewalk and the road surface, and on the right edge of the driving lane or the outer edge of the shoulder. They are an important component of road ancillary facilities. Inspections of existing road curbstones have revealed that cement concrete curbstones are prone to surface defects such as looseness, peeling, chipped edges, and broken corners. These defects severely affect the overall appearance of the road surface and the quality of the ancillary works. Replacement and repair are extremely troublesome and difficult, and also waste a significant amount of manpower, material resources, and financial resources.

[0005] Compression casting technology applies pressure during concrete pouring to rapidly shape components, significantly improving the mechanical and durability properties of concrete components while increasing production efficiency. Using this technology to produce curb stones will effectively address issues such as surface loosening, peeling, chipped edges, and corner breakage common in cement concrete curb stones. However, a mature on-site construction system for concrete curb stones has not yet been developed. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a concrete curbstone walking compression casting molding machine, which can compress cast-in-place concrete using a hydraulic actuator to produce curbstones with better mechanical properties and durability. The produced curbstones are installed in place using a component conveyor belt and a telescopic boom, which can save a lot of labor.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0028] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0029] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a walking compression casting and molding machine for concrete curb stones, such as... Figure 1As shown, the system includes a base with guide posts at its four corners. Along the long side of the base, a sliding arm 5 is positioned between every two guide posts. The long side of the base is parallel to the curbstone installation position after the molding machine is positioned on the road. The guide posts are threaded posts with external threads. Guide holes, slightly larger than the guide posts, are located at both ends of the sliding arm 5, allowing the sliding arm 5 to slide relative to the guide posts. The sliding arm 5 is secured to the guide posts by two fixing nuts, one above and one below. The height of the sliding arm 5 from the ground can be adjusted by adjusting the position of the fixing nuts as needed.

[0030] The sliding boom 5 has an inverted T-shaped groove, with the grooves of the two sliding booms 5 facing opposite directions. A telescopic boom 13 is installed within the groove. It is understood that the non-extending end of the telescopic boom 13 is fixedly equipped with a T-shaped sliding seat for mounting the telescopic boom 13 onto the sliding boom 5. The T-shaped sliding seat cooperates with the inverted T-shaped groove, allowing the telescopic boom 13 to slide relative to the sliding boom 5, but it will not move vertically. It is understood that the telescopic boom 13 uses existing technology, such as a hydraulic telescopic rod.

[0031] like Figure 1 As shown, the tops of the four guide columns are fixedly connected to the top steel beam 3. The top steel beam 3 is frame-shaped, and multiple crossbeams are fixedly connected to its top. Several oil supply tanks 1 and several water supply tanks 2 are fixedly mounted on the crossbeams. Several hydraulic actuators 4 are fixedly connected to the long bottom side of the top steel beam 3. In this embodiment, four hydraulic actuators 4 are used, and they are fixedly connected to the top steel beam 3 via screws and nuts. The hydraulic actuators 4 utilize existing technology to convert hydraulic energy into mechanical energy, such as telescopic hydraulic cylinders.

[0032] like Figure 1 As shown, the top of the output end of the telescopic boom 13 is connected to the concrete clamp 6 via a cable. By controlling the length of the cable between the concrete clamp 6 and the telescopic boom 13, the height of the concrete clamp 6 relative to the ground is controlled. This can be achieved by fixing a pulley at the output end of the telescopic boom 13, with the cable mounted on the pulley. One end of the cable is connected to the concrete clamp 6, and the other end can be connected to a winch (not shown in the figure). The winch is fixedly mounted on the base, ensuring it does not obstruct construction operations.

[0033] A water spraying device 9 is also installed at the bottom of the output end of the telescopic boom 13. Both the concrete clamp 6 and the water spraying device 9 adopt existing technology. The concrete clamp 6 can clamp and fix the component. The water spraying device 9 includes a nozzle and a water pump. One end of the water pump is connected to the nozzle and the other end is connected to the water supply tank. Power is output to the water pump, which can extract water from the water supply tank and deliver it to the nozzle for spraying.

[0034] like Figure 1 , Figure 2 As shown, a component conveyor belt 10 is also provided on the base, and the number of component conveyor belts 10 corresponds to the number of hydraulic actuators 4. One end of the component conveyor belt 10 is located below the hydraulic actuators 4, and the other end is located below the telescopic boom. Support devices 11 are provided on both sides of the component conveyor belt 10. It can be understood that the component conveyor belt 10 adopts existing technology and achieves cyclic rotation under the drive of a power source. In this embodiment, a support plate (not shown in the figure) is connected between the support devices 11 on both sides of the component conveyor belt 10. The support plate is attached to the lower side of the component conveyor belt 10 to support the component conveyor belt 10 and prevent the pressure or weight above from damaging the component conveyor belt 10.

[0035] like Figure 1 As shown, multiple mold base plates are fixedly installed on the centerline of the component conveyor belt 10 for connection with the concrete steel mold 7. A pressure plate is fixedly connected to the output end of the hydraulic actuator 4, and the center of the pressure plate corresponds to the center of the mold base plate. During pouring, the component conveyor belt 10 moves one mold base plate directly below the pressure plate. Then, the operator assembles and fixes the concrete steel mold 7 to the mold base plate and pours concrete aggregate into it. Then, the output end of the hydraulic actuator 4 is lowered, thereby compressing the concrete aggregate in the concrete steel mold 7 and the mold base plate by the pressure plate. The concrete compression pouring process can greatly shorten the component forming time. After compression, the concrete steel mold 7 is removed to obtain the curbstone 8. At this time, the component conveyor belt 10 can withstand the pressure from above under the support of the support device 11.

[0036] It is understandable that a concrete curbstone walking compression casting molding machine also includes a hydraulic power control section. The hydraulic power control uses existing technologies, such as conventional engines, hydraulic pumps, hydraulic motors, gearboxes, transmission devices, and hydraulic control systems. The oil supply tank supplies oil to the hydraulic power control section. The hydraulic actuators, telescopic boom, component conveyor belt, water spraying device, and winch are all powered by the hydraulic power control section. Workers control the start or stop of the hydraulic actuators, telescopic boom, component conveyor belt, water spraying device, and winch through the hydraulic control system. For example, the engine can drive the gearbox, and a power take-off unit installed on the gearbox can drive the water pump. The water pump generates the main power to spray the liquid inside the water supply tank through the nozzles. It should be noted that this embodiment does not involve improvements to the hydraulic power control section; the connections between each component and the hydraulic power section can use existing technologies. The number of oil and water supply tanks is set according to actual needs; for example, multiple water spraying devices can each be connected to one water supply tank.

[0037] like Figure 2As shown, the bottom of the base is also equipped with multiple sets of forward rollers 12. It is understood that the hydraulic power control unit can drive the forward rollers. The hydraulic power control unit is located inside or on one side of the base and must not obstruct construction operations; the arrangement of each hydraulic circuit must also not obstruct construction operations.

[0038] Working principle:

[0039] like Figure 2 As shown, curbstone installation slots are set on both sides of the road. The molding machine is driven to the middle of the road where the curbstone needs to be installed. The concrete steel mold 7 is placed on the component conveyor belt 10 at the position aligned with the center of the hydraulic actuator 4. Then, concrete aggregate is poured. After the pouring is completed, the hydraulic actuator 4 is controlled to apply pressure to the concrete aggregate and maintain it for 2-3 minutes. After the pressing is completed, the hydraulic actuator 4 is raised and the concrete steel mold 7 is disassembled to produce the curbstone 8.

[0040] Next, control the component conveyor belt 10 to transport the curb stone 8 to both sides of the road. When the curb stone 8 is transported to the non-telescopic end of the telescopic boom 13, close the component conveyor belt 10. The workers use concrete clamps 6 to clamp the curb stone 8 and fix it. Then, control the telescopic boom 13 to extend and move the curb stone to the installation position.

[0041] Once the curbstone 8 is moved above the curbstone installation slot, the concrete clamp 6 is lowered via cable to complete the installation of the curbstone. Finally, the water spraying device 9 sprays water to cure the installed curbstone 8. After completing the above steps, the molding machine moves to the next installation position via the forward roller 12 to repeat the steps.

[0042] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
