Conventional all-in-one machines cannot perform UHPC concrete construction well. Therefore, it is necessary to develop a UHPC concrete intelligent placing and leveling all-in-one machine. Utility Model Content

[0004] The purpose of the utility model is to provide a UHPC concrete intelligent placing and leveling integrated machine to solve the above technical problems.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0034] This utility model is a UHPC concrete intelligent all-in-one placing and leveling machine, designed for integrated placing, paving, and leveling of concrete pavements. This machine is primarily suitable for large-width pavement construction. While well-suited for integrated placing and leveling of UHPC high-performance concrete, it can also be applied to other types of concrete pavements.

[0035] like Figure 1 、 Figure 2 As shown, the machine comprises a main truss 1, a material discharging mechanism, a material distribution mechanism, and a leveling mechanism. Traveling mechanisms are installed at both ends of the main truss 1. The traveling mechanisms have running wheels 8, which drive the machine longitudinally along the construction surface during construction. The forward direction of the machine is considered the front.

[0036] The machine's travel mechanism typically includes a travel base 13 and travel wheels 8. The travel wheels 8 are driven by a motor to move the travel base 13 and the entire machine. Specifically, the travel wheels 8 can be rubber or steel. The motor driving the travel wheels is equipped with a frequency converter or a speed reducer.

[0037] The unloading mechanism is used to unload concrete materials. Concrete materials are injected into the unloading mechanism through cement tankers or pump trucks. The concrete is transported horizontally in the unloading mechanism and then unloaded through the unloading port. The falling speed of the concrete material is adjusted through the unloading port, thereby achieving preliminary control of the pavement thickness.

[0038] The spreading mechanism is located behind the unloading mechanism and is used to further spread the concrete laterally. This mechanism is typically a motor-driven spreading auger 2, which rotates to initially level any uneven areas of the material. The spreading auger 2 is positioned laterally along the main truss 1. One end of the spreading auger 2 is connected to the motor drive mechanism, which drives its rotation. This rotation allows the auger 2 to move any excess concrete protruding from one location to another.

[0039] The leveling mechanism is located behind the material spreading mechanism and is used to vibrate and level the concrete surface after the initial leveling of the material spreading to achieve fine leveling. The leveling mechanism mainly includes a vibrating screed plate 3. The vibrating screed plate 3 is arranged along the transverse direction of the main truss 1.

[0040] Through the coordinated construction of the unloading mechanism, the spreading mechanism, and the leveling mechanism, the integrated unloading, spreading, and leveling construction of the concrete pavement is realized. Figure 4 、 Figure 5 shown.

[0041] like Figure 4 As shown, in a specific implementation, the unloading mechanism includes a unloading bin 4 and a feeding spiral auger 5 arranged in the unloading bin 4. The upper end of the unloading bin 4 is open, and a unloading port is arranged at the lower end. A feeding spiral auger 5 is arranged inside the unloading bin 4, and one end of the feeding spiral auger 5 is connected to the power of the motor drive mechanism, and is driven to rotate by the motor drive mechanism, thereby realizing horizontal lateral transportation of the concrete material. The unloading bin 4 is arranged on the main truss 1 and arranged along the lateral direction of the main truss 1. An opening and closing plate 6 is provided at the unloading port at the lower end of the unloading bin 4, and the opening and closing plate 6 can be moved to control the size of the opening and closing degree of the unloading port to control the unloading speed of the concrete material. Specifically, the opening and closing plate 6 is arranged close to the unloading port, and an opening and closing plate pushing cylinder 7 is also provided. Generally, multiple opening and closing plate pushing cylinders 7 need to be provided, and the multiple opening and closing plate pushing cylinders 7 are synchronously moved. The opening and closing plate pushing cylinder 7 pushes the opening and closing plate 6, thereby realizing the control of the opening and closing degree of the unloading port. Specifically as Figure 7 shown.

[0042] Alternatively, multiple sections of opening and closing plates 6 can be set, and each section of opening and closing plates 6 is pushed and controlled by an opening and closing plate pushing cylinder 7, and each opening and closing plate pushing cylinder 7 is controlled separately. A monitoring sensor is set at the discharge port corresponding to each opening and closing plate 6, and the amount of material falling is monitored by the monitoring sensor so that the control system can better control the opening and closing degree of the discharge port through the opening and closing plate 6, thereby controlling the paving height and flatness of the road surface. Generally, multiple monitoring sensors can be set, and multiple monitoring sensors are set at horizontal intervals along the discharge port of the discharge bin 4. After each construction is completed, the machine is flushed in time to clean the residual material splashed on the surface of the detection sensor to ensure normal use next time.

[0043] Furthermore, in order to facilitate feeding, a feeding bin 12 is provided at one end of the lower feeding bin 4. Figure 4 、 Figure 6As shown, the loading bin 12 and the lower hopper 4 are actually an integrated, interconnected structure. The lower hopper 4 is located between the two running mechanisms of the main truss 1, while the loading bin 12 is located outside of the running mechanisms. A feed auger 5 also extends into the loading bin 12. During operation, concrete is added to the loading bin 12 by a concrete tanker or overhead pump. The feed auger 5 then delivers the concrete to various locations within the lower hopper 4. This arrangement facilitates feeding and loading materials into the machine.

[0044] In order to prevent the concrete material from adhering to the inner wall of the lower hopper 4, a number of vibrators 10 can be set on the outer wall of the lower hopper 4, and a number of vibrators 10 can be set at intervals along the outer wall of the lower hopper 4 to continuously vibrate during operation to prevent the material from adhering to the inner wall of the lower hopper 4. Figure 3 shown.

[0045] The material distribution mechanism of the machine is a material distribution spiral auger 2. If the material distribution spiral auger 2 required is longer, the material distribution spiral auger 2 can be divided into sections.

[0046] The main truss 1 of the machine preferably adopts a modular assembly structure, so that the main truss 1 of appropriate length can be set according to actual needs. In addition, the modular main truss is easy to transport.

[0047] The vibrating screed plate 3 of the machine has the function of vibrating the concrete to raise the slurry and level the concrete. A vibrator is set on the upper end of the vibrating screed plate 3 to promote the vibrating screed plate 3 to vibrate at high frequency to achieve the purpose of raising the slurry and leveling the concrete. Figure 8 As shown, the vibrating screed plate 3 is mounted on the rear side of the main truss 1 using a number of cantilever frames 9. The cantilever frames 9 are roughly L-shaped and are used inverted during assembly. The upper portion of one end of the cantilever frame 9 is fixedly connected to the side of the main truss, and the lower end of the other end of the cantilever frame 9 is fixedly mounted on the vibrating screed plate 3. Multiple cantilever frames 9 are provided, and the multiple cantilever frames 9 jointly suspend the vibrating screed plate 3. Furthermore, shock-absorbing rubber pads are usually provided between the vibrating screed plate 3 and the cantilever frames 9. This can reduce the impact of the vibration of the vibrating screed plate 3 on the cantilever frames 9 and the main truss 1.

[0048] The machine is provided with a plurality of vibrating rods 11 at the lower end of the discharge port of the discharge hopper 4, and the vibrating rods 11 are in a horizontally arranged state. A plurality of vibrating rods 11 are arranged at intervals along the discharge port of the discharge hopper 4. The vibrating rods 11 vibrate and compact the concrete, and can vibrate and compact the concrete in time after laying. In addition, it also has the function of preventing the concrete material from clogging the discharge port. This setting can vibrate and compact the concrete material in time after the concrete material falls and is spread, thereby improving the vibration effect and ensuring the density of the paved road surface. In order to be able to realize the direct arrangement of the vibrating rod at the discharge port of the discharge hopper, the vibrating rod is arranged horizontally, and the horizontal arrangement can improve the vibration effect. The arrangement of the vibrating rod in this machine has significant advantages over the vertical arrangement of the traditional vibrating rod.

[0049] The machine's main truss (1) is mounted on the traveling mechanism at both ends and can be attached to the traveling mechanism via a lifting cylinder. The lifting cylinders can be used to raise and lower the main truss (1) to adjust the working height. After work is completed, the main truss (1) can be raised using the lifting cylinders, allowing the working area below the machine to be flushed using a flushing device.

[0050] Standing platforms can be installed on the front and rear sides of the main truss 1 for workers to stand on. The standing platform on the rear side of the main truss 1 can be fixed to the outer side of the cantilever frame 9. The standing platform is also equipped with an electrical cabinet. The machine is equipped with a hydraulic system to provide power to the hydraulic components of the machine.

[0051] When in use, this integrated concrete distribution and leveling machine first fills the loading hopper 12 with concrete, and the feed auger 5 evenly delivers the concrete to the discharge hopper 4. Then, driven by the opening cylinder 7, the opening and closing plate 6 opens relative to the discharge port, while the vibrating rod 11 simultaneously vibrates at a high frequency. Driven by the traveling mechanism, the entire machine slowly moves forward. The distribution auger 2 smoothes and transports uneven concrete protrusions horizontally. Finally, the vibrating screed plate 3 performs vibration to extract the concrete and achieve precision leveling.

[0052] The utility model is an intelligent all-in-one UHPC concrete placing and leveling machine, which is suitable for the integrated construction of placing and leveling UHPC concrete. By rationally arranging the feeding mechanism, vibration component, placing mechanism and leveling mechanism, the construction quality can be guaranteed and the construction efficiency can be improved.
