Description

Technical Field

[0001] The utility model relates to the technical field of road construction equipment, in particular to a mobile road surface repairing device. Background Art

[0002] Mobile concrete mixing plants play a vital role in road construction. However, during their development, some background technologies have encountered shortcomings that have limited their flexibility and adaptability in practical applications. For example, concrete mixing plants commonly used in road construction require separate installations for the mixing, storage, and metering devices. These installations are transported and installed on-site separately. Consequently, the entire system requires a large floor space, is cumbersome to transport, and requires complex installation and commissioning. This leads to low site space utilization, hindering construction progress. This problem is particularly acute in confined work areas and in road construction applications where movement is frequent.

[0003] Local repair requirements for highway expansion joints and bridge deck pavement require lane closures to be extended overnight, resulting in a short construction window of approximately 10 hours. Repairs to concrete cracks, chipped corners, and thin layers in toll plazas require traffic to resume within four hours of construction.

[0004] In the current implementation scheme, concrete is mixed manually and only 10m3 can be constructed per day. 3 Rapid hardening concrete, so its efficiency is low and consumes a lot of manpower.

[0005] Truck mixers can only be used for low- to medium-strength cement. In high-strength cement applications, they cannot fully mix the materials, resulting in inadequate performance of high-strength concrete. Automatic batching, ready for use and mixing at any time, is not possible. Cement mix ratios are arbitrary, and precise metering is impossible. Multiple factors contribute to substandard strength in the finished product.

[0006] In addition, existing mixing station equipment uses multiple machines, occupies a large area, and cannot be moved. Its solution is too large for use scenarios that require quick response and flexible proportioning, and cannot meet the changing needs of on-site operations. Utility Model Content

[0007] This utility model provides a mobile pavement repair device with an integrated vehicle-mounted platform. It offers comprehensive solutions for rapid concrete delivery, material mixing, mixing, discharging, and thermal insulation maintenance. It avoids unstable factors in various links of the pavement repair process, thereby ensuring the stability of the concrete's strength after curing.

[0008] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a mobile road repair equipment, comprising: a carrier, the carrier is provided with a vehicle body beam; a frame, the frame is a rectangular frame structure arranged on the vehicle body beam; a vertical mixer, the vertical mixer is arranged at one end of the interior of the frame close to the tail of the vehicle body beam, and the discharge hopper of the vertical mixer extends to the outside of the frame; a raw material box, the raw material box is provided in plurality and distributed above the vertical mixer, and each of the raw material boxes is connected to the feed port of the vertical mixer through a feeding mechanism; a generator, the generator is arranged at one end of the interior of the frame away from the vertical mixer; a control cabinet, the control cabinet is arranged on one side of the vertical mixer, and is electrically connected to the generator, the vertical mixer and each of the feeding mechanisms.

[0009] Preferably, it further includes a tool cabinet, which is provided in multiple locations and is distributed in the middle of the frame and on both sides of the vehicle body beam.

[0010] Preferably, each of the tool cabinets is provided with a tool interface, and each of the tool interfaces is movably connected to a pneumatic pick, an electric pick, a hair dryer, a welding machine, a heating pad and a high-pressure water gun.

[0011] Preferably, a pedestal is provided on one side of the frame corresponding to the vertical mixer, a crane is provided on the top of the pedestal, and a hydraulic control valve of the crane is electrically connected to the control cabinet.

[0012] Preferably, the raw material box includes a gravel box, a sand box, an additive box and a water tank; weight sensors are respectively provided at the bottom of the gravel box, the sand box and the additive box, and extend into the feed port of the vertical mixer through a screw conveyor; a metering pump is provided between the water tank and the feed port of the vertical mixer; each of the weight sensors, each of the screw conveyors and the metering pump is respectively electrically connected to the control cabinet.

[0013] Preferably, slide rails and traction mechanisms are provided on both sides of the top of the frame along the length direction, and the frame also includes a telescopic canopy that slides on the slide rails. The two ends of the telescopic canopy are respectively connected to the end of the frame and the traction mechanism, and the traction mechanism is electrically connected to the control cabinet.

[0014] The beneficial effects of this utility model are that the mobile pavement repair equipment implements an integrated vehicle-mounted platform and provides a comprehensive solution for rapid concrete delivery, material addition and proportioning, mixing, discharging, and thermal insulation and maintenance. This eliminates unstable factors in various stages of the pavement repair process, thereby ensuring the stability of the concrete's strength after curing. During the rapid bridge deck pavement repair process, the operator uses a control cabinet to achieve intelligent batching. After setting the discharge weight, the screw conveyors batch the materials according to the proportion, and the vertical mixer discharges the materials according to the control cabinet's instructions. This eliminates the need for manual intervention during the batching and mixing process, saving time for emergency repair work. The tool cabinet is used to store common tools used in the pavement repair process and receives power, electricity, compressed air, or high-pressure water through a tool interface, facilitating construction operations and improving work efficiency. In particular, the heating pad ensures that the pavement maintains a strict temperature profile in extreme weather conditions, ensuring effective cement curing. A crane is used to hoist materials into corresponding raw material bins, thus mechanizing the filling process and reducing worker labor intensity. The retractable canopy can prevent the material in the raw material box from being blown out by the wind and causing spillage during the movement of the vehicle. It can also provide dust protection for the equipment in the rack and prevent foreign matter from falling into the raw material box.

[0015] In summary, this mobile pavement repair equipment achieves precise batching of repair materials through scientific measurement, automates loading, mixing, and discharging with a single click, and enhances the adaptability and flexibility of highway repair operations across multiple application scenarios. Combined with specialized rapid repair materials, this equipment can rapidly repair localized cement concrete defects on highways within two hours, improving construction efficiency and repair quality, saving manpower, and effectively reducing overall maintenance costs.
