DETAILED DESCRIPTION

[0028] like Figures 1 to 8 As shown, the present invention provides a multifunctional integrated road maintenance vehicle, comprising: a maintenance vehicle body, the maintenance vehicle body comprising a vehicle-mounted platform 1 and an equipment platform 16 for carrying maintenance equipment, a plurality of the equipment platforms 16 are slidably mounted on the vehicle-mounted platform 1, a hydraulic pump 2, a dust removal device 3, a sandblasting machine 4, a hydraulic air compressor 5, and a storage bin 7 are sequentially mounted on one half side of the vehicle-mounted platform 1 along the walking direction, and a generator set 14, a road roller 13, a shot blasting machine 12, a crack filling machine 11, a grouting machine 10, an electric control box 15, and a storage bin 7 are sequentially mounted on the other half side of the vehicle-mounted platform 1 along the walking direction. The storage bin 7 is installed at the rear of the vehicle-mounted platform 1, and a mixer 6 is installed between the storage bins 7 on both sides. A loading device 8 for loading and a ladder 9 for climbing to the vehicle-mounted platform 1 are installed at the rear of the vehicle-mounted platform 1. The storage bin 7 on one half of the vehicle-mounted platform 1 is used to store new materials, and the storage bin 7 on the other half of the vehicle-mounted platform 1 is used to store old materials. The hydraulic air compressor 5 provides working air to the sandblasting machine 4 through the air supply pipeline. The mixer 6 adopts a horizontal double-shaft forced stirring structure. The driving actuator of the mixer 6 is preferably an electric motor or a hydraulic motor, and the number of driving elements is preferably 1.

[0029] The working principle of the above technical solution is as follows: Figure 1 and Figure 8, using the vehicle-mounted platform that meets the latest VI emission standards as the carrying platform, the above maintenance equipment is transported to the vehicle-mounted platform 1 by a transport trolley. When the maintenance vehicle body is working, the driving force is obtained through the power take-off port to provide the working power source for the hydraulic pump 2. The hydraulic pump 2 provides hydraulic driving oil to the hydraulic air compressor 5 to drive the hydraulic air compressor 5 to work. The hydraulic air compressor 5 outputs compressed air to provide an air source for the sandblasting machine 4 to perform sandblasting work. At the same time, the compressed air output by the hydraulic air compressor 5 also provides an air source for grouting for the grouting machine 10. The hydraulic pump 2 provides hydraulic oil to the feeding device 8 to drive its work so as to realize the automatic loading of new and old materials into the storage bin 7. The hydraulic system provides hydraulic oil to the hydraulic motors of the left and right feeding devices 8 at the rear of the vehicle to drive their reverse work. The retrieval of new and old materials stored in the storage bin 7 can be realized; the two lifting cylinders of the shot blasting machine 12 are simultaneously provided with oil through the hydraulic system to enable it to complete the extension work; the generator set 14 generates output three-phase AC power, which is supplied to the drive motor on the vehicle platform shot blasting machine 12 to power it, so as to complete the preliminary shot blasting cleaning work of the shot blasting machine on the construction surface before construction; the generator set 14 generates output three-phase AC power and supplies it to the drive motor of the dust removal device 3 on the vehicle platform to perform dust removal operation when the shot blasting machine 12 is operating, thereby realizing environmentally friendly operation of the shot blasting operation; the generator set 14 outputs three-phase AC power, which is supplied to the drive motor on the sand blasting machine 4 placed on the vehicle platform 1, and the motor drives the sand blasting machine to work, and the vehicle The platform 1 moves forward to complete the sandblasting operation on the work surface; the generator set 14 outputs power to supply power to the mixer 6 at the rear of the vehicle platform to drive the mixing material, which can realize the old road mixture collected after on-site maintenance and excavation, and is lifted by the feeding device 8 and added to the mixer 6 at the rear of the vehicle platform, and then by adding new emulsified asphalt material to the mixer 6, the driving motor on the mixer 6 is powered to work, and the original old road mixture after excavation in the mixer 6 and the newly added asphalt are mixed evenly and then discharged for use, which can realize the re-mixing and secondary utilization of the original road mixture after excavation at the maintenance point in the mixer 6, thereby realizing the on-site recycling of old materials, turning waste into treasure and saving energy. The advantages of environmental protection and maintenance; after the equipment arrives at the maintenance point, the new aggregate and newly added asphalt stored in the storage bin 7 on the vehicle in advance can be quickly taken out and added to the mixer 6, and the mixture can be output after the driving motor on the mixer 6 is driven to mix evenly. The output supply of new mixed materials to local road maintenance points can also be realized, and aggregates and liquid asphalt can be continuously loaded from the outside into the mixer 6 for mixing and continuously output for use. The block asphalt can also be fed into the mixer 6 to heat and melt the block asphalt to the use temperature using the heating function of the mixer 6, and then the stone is added to the mixer for mixing and mixing, and then the mixture is discontinuously output for use. The equipment can realize various production methods of asphalt mixtures through different feeding working modes of the rear mixer 6.The grouting machine 10, mounted on the platform, utilizes two materials: a two-component epoxy resin adhesive and a curing agent. Each material is stored in a separate tank. The grouting machine 10 electrically heats the materials in each tank, reducing their viscosity and facilitating pumping. A stirring motor on the tank top powers a stirrer within the tank, heating and stirring the materials evenly. The two heated materials are then transported out of the tank via separate delivery pumps driven by variable-frequency motors. The speeds of the variable-frequency motors in the two pumps are electronically controlled to achieve dynamic mixing of the two materials in varying ratios, creating a two-component mixture for delivery to the cracks. The grouting material is then fed through a grouting gun nozzle at the end of the delivery pipeline. High-pressure air is supplied to the nozzle via a hydraulic air compressor 5. Finally, the grouting material is pressurized by the high-pressure air introduced into the nozzle and delivered, completing the pressurized grouting operation. This ensures the density of the grouting material within the cracks during continuous grouting. By flexibly adjusting the ratio of the curing agent in the two-component mixture, the curing time of the materials can be adjusted to meet the needs of various construction conditions. The heating temperature of the two materials can be precisely adjusted and controlled to adapt to the impact of seasonal ambient temperature changes on the curing time of the materials. The ladder 9, located symmetrically on the left and right sides of the discharge port of the rear mixer 10, is vertically mounted on the rear of the vehicle, allowing operators on both sides to easily access the vehicle for inspection and maintenance. The caulking machine 11 device is arranged in front of the grouting machine 10 device on the vehicle platform. The caulking machine 11 device adopts a square melting box inside. The outer layer of the inner square melting box is a square heat transfer oil heating interlayer. The outermost layer of the heat transfer oil heating interlayer is also provided with a square heat insulation layer. The block asphalt caulking glue is added from the outside and enters the inner square melting box. A heating device is provided at the lower end of the caulking machine 11 device, and a pumping pipeline with heat insulation discharge is also provided, as well as a caulking glue gun for caulking at the end of the delivery pipeline. The caulking glue gun can realize electric control heating and has its own heat insulation hose. First, the block asphalt glue used for caulking is delivered into the innermost square melting box, and passes through the square heat transfer oil heating interlayer on the outer layer of the square melting box. The heat transfer oil in the layer is automatically controlled by the controller in the electric control box 15 to heat the heat transfer oil and indirectly add the block hot asphalt glue until it melts into liquid and can be used at the temperature. The heating is stopped to achieve automatic heat preservation. The caulking asphalt glue dissolved and heated to the use temperature in the square melting box is transported by opening the discharge valve at the lower end of the square melting box and the conveying pump. The conveying pump is driven by a variable frequency motor. The speed control mode of the variable frequency motor can be controlled in the electric control box 15 to adjust the speed of the conveying pump, so as to match and adjust the amount of caulking asphalt glue for different sizes. The forward and reverse operation of the variable frequency motor can be controlled in the electric control box 15, so as to realize the forward transmission of the conveying pump to feed the caulking and the reverse recovery of the residual material at the caulking nozzle end. The conveying material adopts an insulated and electrically heated insulation hose.It can realize the advance electric preheating of the conveying hose, realize the constant temperature conveying of the grouting asphalt rubber material without temperature loss during the conveying process, ensure the constant output temperature of the grouting rubber material, and thus realize the stability of the grouting operation quality. The shot blasting machine 12 is placed on the vehicle platform, horizontally in front of the grouting machine 11, and the shot blasting machine 11 is suspended on the square swing hanger on the vehicle platform. The square swing hanger is connected and fixed to the vehicle platform through the lower end rotating shaft and the rotating shaft sleeve. The square swing hanger is extended by two synchronous oil cylinders, and the swing hanger can be realized with the lower end longitudinal rotating shaft as the axis center. It rotates downward in the circumferential direction to realize the shot blasting machine 12 to be lowered from the vehicle position to the ground on the right side of the vehicle when in use. After use, the frame swing hanger is driven by the retraction of the two synchronous oil cylinders, and drives it to rotate upward in the circumferential direction to realize the shot blasting machine 12 to be lifted from the ground on the right side of the vehicle and placed back on the vehicle platform after use. The shot blasting machine 12 is powered by the power output of the generator set 14, which supplies power to the drive motor on the shot blasting machine 12 to perform the shot blasting and grinding operation on the working surface of the shot blasting machine. The roller 13 is placed on the vehicle platform, horizontally located in front of the shot blasting machine 12. The roller 13 is started by its own engine unit and operates in a hand-held manner. It can achieve the surface shaping work of the road surface after small repairs by vibrating and compacting. The entire vehicle operation is controlled by operating the electronic control box 15, which can realize the overall control of all hydraulic loads and motor-driven loads on the vehicle, so that the control execution can complete all functions.

[0030] The beneficial effects of the above technical solution are: through the flexible configuration of the various working devices and the optimized and ingenious arrangement of the vehicle structure, multiple functions required for daily highway maintenance are integrated into a single vehicle platform. This allows for intermittent or continuous pouring of asphalt mixture production, shot blasting before pavement maintenance, rolling and shaping after new pavement repair and maintenance, sandblasting after pavement completion, pavement crack filling, epoxy resin grouting, excavation, AC power generation, compressed air, and dust removal during pavement operations. This allows for rapid construction, rapid site transfer, and emergency maintenance in all operating procedures. Compared with the existing conventional maintenance construction which requires a combination of multiple scattered construction equipment, this multifunctional integrated road maintenance vehicle equipment is used as a whole in various daily maintenance of steel bridge decks. First of all, it has richer functions, the layout of various construction devices is more concentrated, compact and beautiful, the conversion is more flexible and convenient, the mobile vehicle platform can be transferred more quickly, and the construction equipment is combined and dispatched on the same platform, making it more convenient and time-saving, which can save a lot of construction time, manpower and financial resources, and solve the problems of inefficient, troublesome and time-consuming operation processes of multiple equipment required for existing road and steel bridge deck maintenance and high cost of dispatching multiple equipment; by installing multiple maintenance equipment on the equipment platform 16 respectively, and installing the equipment platform 16 on the vehicle platform 1 in a sliding manner, it is convenient to adjust the installation position of the maintenance equipment.
