Description

Technical Field

[0001] This utility model relates to the field of pouring device technology, and in particular to a UHPC automatic mixing and pouring vehicle. Background Technology

[0002] In small-scale UHPC reinforcement construction, due to the dispersed work sites (such as bridge bearings and cracks in hydraulic dams) and limited construction space, it is necessary to integrate the mixing and pouring equipment onto transport vehicles to achieve "immediate transportation, mixing, and pouring" to meet the stringent timeliness requirements of UHPC construction (avoiding loss of fluidity and steel fiber settling). However, existing vehicle-mounted equipment installation methods generally suffer from insufficient stability, becoming a key bottleneck restricting project quality and construction safety. On the one hand, the UHPC mixing and casting process is accompanied by multiple dynamic loads, and the existing simple installation structure is difficult to withstand the load impact. If the stability of the installation structure is insufficient, it is easy to cause the axis of the mixing tank to deviate, resulting in irregular convection of materials in the tank, causing material waste and construction delays.

[0003] On the other hand, the road conditions at the construction site are complex. If the stability of the vehicle-mounted equipment is insufficient, the shaking of the equipment during the pouring stage will cause pouring deviations, affecting the construction quality and efficiency.

[0024] Please see the appendix Figure 1-11 An embodiment of the UHPC automatic mixing and pouring vehicle provided by this utility model includes a transport vehicle 10, a connecting assembly 20, and a mixing and pouring mechanism. The transport vehicle 10 has a carrying platform 11. It should be noted that the lateral direction in this application refers to the width direction along the transport vehicle 10. The specific design is as follows: The connecting assembly 20 includes a limiting part 21, a reinforcing part 22, and a supporting part 23. The limiting part 21 is used to restrict the horizontal displacement of the mixing and pouring mechanism and is connected to the bearing platform 11. One end of the limiting part 21 is fixedly connected to the inner wall of the transport vehicle 10. The reinforcing part 22 is obliquely placed between the inner wall of the transport vehicle 10 and the top of the limiting part 21. The supporting part 23 is connected to the end of the bearing platform 11 near the rear of the vehicle. The mixing and pouring mechanism includes a mixing assembly 30, an installation assembly, and a screw conveyor assembly 40. The installation assembly includes a mixing mounting frame. The mixing assembly 30 includes a mixing bracket 32 ​​and multiple columns 39 protruding from the bottom of the mixing bracket 32. The mixing bracket 32 ​​is fixed to the bottom of the mixing assembly 30. The columns 39 are connected to the support platform 11 and abut against the limiting part 21. The mixing bracket 32 ​​is connected to the top of the limiting part 21. The mixing assembly 30 has a discharge chute 31. The screw conveyor assembly 40 is inclined. The lower end of the screw conveyor assembly 40 is connected to the support platform 11 and located directly below the discharge chute 31. The higher end of the screw conveyor assembly 40 is connected to the support part 23.

[0025] Specifically, the UHPC automatic mixing and pouring vehicle in this application includes a transport vehicle 10, a connecting assembly 20, and a mixing and pouring mechanism. The transport vehicle 10 serves for transportation and loading, and has a support platform 11 for installing other components. The connecting assembly 20 ensures the stability of the mixing and pouring mechanism when it is installed on the support platform 11 of the transport vehicle 10, thereby ensuring stability during subsequent mixing and pouring processes. The connecting assembly 20 includes a limiting part 21, a reinforcing part 22, and a supporting part 23. The limiting part 21 is used to restrict... The horizontal displacement of the mixing and pouring mechanism prevents horizontal deviation during operation. Therefore, it is fixed on the bearing platform 11 for installation and connection of the mixing and pouring mechanism. One end of the limiting part 21 is fixedly connected to the inner wall of the transport vehicle 10 to improve the overall connection and stability between the limiting part 21 and the transport vehicle 10. The reinforcing part 22 is used to further strengthen the structural rigidity between the limiting part 21 and the transport vehicle 10. It adopts an oblique placement to spread the distribution range of the connection points, making the stress more uniform.

[0026] The mixing and pouring mechanism includes a mixing assembly 30, an installation assembly, and a screw conveyor assembly 40. The mixing assembly 30 is used to mix and stir materials and additives. The installation assembly is used for mounting and connecting the mixing assembly 30, and includes a mixing mounting frame 32 and multiple columns 39 protruding from the bottom of the mixing mounting frame 32. The mixing mounting frame 32 is fixed to the bottom of the mixing assembly 30 to facilitate the connection of the entire mixing assembly 30 to the top of the limiting part 21. The columns 39 are used to support the mixing assembly 30 and the carrying platform 11. In this way, the mixing assembly 30 is directly connected not only to the limiting part 21 but also to the entire transport vehicle 10, greatly increasing the connection points and enhancing connection stability. During connection, the columns 39 need to abut against the limiting part 21. 21 is fixed, so when the mixing assembly 30 deviates slightly, it will act as a limiter under the resistance of the limiting part 21 against the column 39; the screw conveyor assembly 40 is used to convey materials into the pump for on-demand pumping and casting, and to reinforce small-volume UHPCs such as bridges, docks, and buildings. To ensure the fluidity of the UHPC and avoid blockage, it is usually inclined, with the lower end located directly below the discharge trough 31. To ensure the stability of its upper end, the support part 23 is used to support the upper end of the screw conveyor assembly 40, so that the upper end of the screw conveyor assembly 40 is installed on the support part 23; preferably, the top of the support part 23 is inclined and matched with the inclination of the screw conveyor assembly 40, so that the installation is more stable and the adaptability is improved.

[0027] In a preferred embodiment of this utility model, the limiting part 21 includes a plurality of support plates 211 arranged laterally at intervals and two limiting plates 212 arranged laterally opposite to each other. The support plates 211 are vertically connected to the bearing platform 11, and the first end of each support plate 211 is fixedly connected to the inner side wall of the transport vehicle 10. The column 39 abuts against the inner wall of the two outermost support plates 211 located laterally. The second end of the two outermost support plates 211 located laterally is respectively connected to a limiting plate 212. The limiting plates 212 are inclined inward in the direction from the front to the rear of the vehicle. The spiral conveying assembly 40 is built between the two limiting plates 212.

[0028] It should be noted that the support plate 211 can support the entire mixing assembly 30 to a certain height, thereby optimizing the fluidity of the UHPC under gravity during mixing and casting, and preventing blockage. Setting multiple support plates 211 increases the number of installation connection points for the mixing assembly 30, thus improving connection stability. In a preferred embodiment of this application, three support plates 211 are used, evenly distributed laterally, resulting in a more uniform distribution of connection points (lines). During installation, the column 39 abuts against the inner walls of the two outermost support plates 211 to achieve a limiting effect. The limiting plate 212 is used to cover the spiral conveying assembly 40. Considering that the width of the spiral conveying assembly 40 is smaller than that of the mixing assembly 30, the limiting plate 212 is inclined, specifically tapering towards the rear of the vehicle, to match the structural dimensions of the spiral conveying assembly 40 and facilitate connection. Preferably, the limiting plate 212 can be in the form of an arc-shaped plate, which has better resistance to deformation.

[0029] It is worth mentioning that corner braces (not shown in the figure) can be added to the outer sides of the two outermost support plates 211 to improve the lateral structural strength, thereby opposing the force of the column 39, reducing the fatigue of the support plates 211, and extending the service life of the equipment.

[0030] In a preferred embodiment of the present invention, the reinforcing part 22 includes a plurality of diagonal bracing rods 221 arranged at intervals along the lateral direction. Each of the support plates 211 is connected to a corresponding diagonal bracing rod 221. The two ends of the diagonal bracing rods 221 are fixedly connected to the inner side wall of the transport vehicle 10 and the top of the support plate 211, respectively.

[0031] It should be noted that multiple diagonal braces 221 are used to correspond to multiple support plates 211, so that each support plate 211 can be connected to one diagonal brace 221 to enhance the structural rigidity. In this application, three diagonal braces are set accordingly, and each diagonal brace 221 is directly placed diagonally between the inner side wall of the transport vehicle 10 (the back side of the cab) and the top of the support plate 211.

[0032] In a preferred embodiment of the present invention, the reinforcing part 22 further includes a cross bracing unit, wherein a cross bracing unit is connected between each two adjacent diagonal bracing rods 221; wherein each cross bracing unit includes a plurality of cross bracing rods 222 spaced apart along the extension direction of the diagonal bracing rods 221, and the cross bracing rods 222 are horizontally placed between two adjacent diagonal bracing rods 221.

[0033] It is worth noting that the cross bracing unit is used to enhance the lateral structural stiffness between the diagonal bracing rods 221, thereby enhancing the overall connection between the various components, facilitating overall stress distribution, and improving structural stability.

[0042] In one embodiment: After the integral mixing and casting mechanism is installed and fixed between the connecting component 20 and the transport vehicle 10, the processing can begin. When mixing is required, the electrically adjustable discharge gate on the large dry material silo 57 will open to put the dry mixture into the primary mixing chamber 531. Then, the primary mixing drive motor 551 will start, driving the two primary mixing shafts 552 to rotate, driving the eight primary mixing dispersion teeth 553 and the two rotating spiral tubes 554 to rotate, performing preliminary mixing and conveying of the dry mixture, so that it is sent into the primary mixing discharge pipe 534 after preliminary mixing. The control cylinder 541 is activated, causing the opening and closing cone block 542 to open, feeding the dry mixture into the control chamber 521. Simultaneously, the quick-opening and closing solenoid valves on the two small liquid hoppers 56 will also open, feeding water and water-reducing agent, along with the dry mixture, through the discharge chute 524, inclined connecting pipe 520, and feed square pipe 335 into the elastic inner cylinder 332. Subsequently, the two synchronous drive motors 342 will start, driving the two drive gears 343 to rotate, which in turn drives the stirring gear ring 344 to rotate around the rotating mounting ring 346, causing the rotating stirring ring 351, stirring drive cylinder 353, and stirring... The mixing plate 354 rotates, which in turn drives the two mixing arm elements 36 and scraper element 37 installed therein to rotate as well. When the scraper element 37 rotates, its centrifugal force causes the sliding frame 373 and the conical scraper 374 to slide outward along the scraper sliding groove 375, so that the outer edge of the conical scraper 374 abuts against the inner wall of the elastic inner cylinder 332 to scrape and provide vertical shearing force, ensuring the mixing effect. When the mixing ring 351 and the mixing arm elements 36 rotate, the mixing gear 362 and the mixing gear ring 344 mesh with each other, causing the mixing mounting shaft 361 to also rotate. The rotating shaft 361 drives the three inclined stirring arms 364 and three wear-resistant stirring blades 365 to rotate as well. When the inclined stirring arms 364 rotate, the inclined mounting block 366 is tilted downwards, and the top of the inclined stirring arms 364 is slidably mounted in the inclined mounting groove 367. The centrifugal force of the stirring mounting shaft 361 causes the inclined stirring arms 364 to slide downwards along the inclined mounting groove 367, achieving a combined motion of revolution and rotation. This generates strong shearing, convection, and diffusion effects on the material during mixing, ensuring effective mixing and increasing the mixing rate. After mixing is complete, the discharge controller 38 is activated, opening the discharge chute 31 and allowing the mixed material to fall into the inclined conveyor frame 41 below. Subsequently, two screw conveyor motors 42 are activated, causing two screw conveyor pipes 43 to rotate and lift the mixed material into the pump for on-demand pumping and pouring, enabling reinforcement work on small-scale UHPC structures such as bridges, docks, and buildings.

[0043] During mixing, the external buffer supply device delivers temperature-controlled buffer solution to the buffer supply pipe 339, which then flows along the supply pipe 333, the annular outlet groove 338, and the annular connecting groove 337 into the hollow cavity 336, providing uniform temperature cooling and elastic buffering for material mixing. When encountering large-diameter, high-proportion coarse aggregates (e.g., crushed stone with a diameter exceeding 40mm) in the dry mix during mixing, the coarse aggregates will push against the conical scraper 374 when they come into contact with it, causing the conical scraper 374 and the sliding frame 373 to slide inward along the scraper sliding groove 375. Alternatively, when the coarse aggregates come into contact with the wear-resistant mixing blades 365, they will also push against the wear-resistant mixing blades 365 and the inclined mixing arm 364, causing them to move upward along the inclined mounting groove 367. This provides an adjustable mixing gap during mixing, thereby preventing jamming and hard impacts, extending the service life of the equipment, and preventing the coarse aggregates from being squeezed and sheared, which would affect the material quality.
