[0022] The walking mechanism 2 and the execution mechanism are arranged below the platform 1, and the central control system 3 and the power system 4 are installed above the platform 1. The walking mechanism 2 of the embodiment is a track walking device, and in addition, other suitable walking mechanisms can also be selected. The central control system 3 is used to control the walking mechanism 2 and the execution mechanism, and the central control system 3 can satisfy the driving and operation functions, so that the operator can drive and monitor the operation of the vehicle. As Figure 3 shown, it is a single-person working mode, and as Figure 4The double-person working mode is shown. The power system 4 is used to provide driving force for the walking mechanism 2 and the execution mechanism, and the walking mechanism 2 drives the equipment to travel after obtaining the driving force. Along the traveling direction of the walking mechanism 2, the walking mechanism 2, the material distribution mechanism 5, the flattening mechanism 6 and the spreading mechanism 7 are arranged in sequence from front to back, and the material distribution mechanism 5, the flattening mechanism 6 and the spreading mechanism 7 are connected to the rear part of the platform 1 through fasteners.

[0023] The leveling mechanism 8 is installed on the front side of the walking mechanism 2, and can use the laser leveling method to detect the height fluctuation of the road in front of the equipment in real time, and feed back the detected signal to the central control system 3. The central control system 3 automatically controls the lifting mechanism 9 to rise and fall through intelligent algorithm, so as to compensate for the road height fluctuation and realize automatic leveling in the traveling.

[0024] The lifting mechanism 9 is installed on the left and right sides of the platform 1, and preferably four independent lifting mechanisms 9 can be provided on the left and right sides of the platform 1, and each lifting mechanism 9 is independently controlled by the central control system 3. Specifically, the bottom of the lifting mechanism 9 is installed on the walking mechanism 2, and the driving output end of the lifting mechanism 9 is installed on the platform 1, and the execution mechanism such as the material distribution mechanism 5, the flattening mechanism 6 and the spreading mechanism 7 is fixedly installed on the platform 1. Therefore, under the driving of the lifting mechanism 9, the execution mechanism can be lifted synchronously with the platform 1, and then the working height of the execution mechanism is adjusted.

[0025] The material distribution mechanism 5, the flattening mechanism 6 and the spreading mechanism 7 of the embodiment are all modularly designed, which can be assembled on site and is convenient for road transportation of the equipment. In addition, the left and right ends of the material distribution mechanism 5, the flattening mechanism 6 and the spreading mechanism 7 are provided with installation interfaces for splicing and widening, so that the paving working width can be easily adjusted through the external connection of the two ends to adapt to the construction requirements of pavements with different widths.

[0026] A conveying belt 10 is arranged between the platform 1 and the traveling mechanism 2, and is used to convey the mixture from outside the device to the distributing mechanism 5. The mixture can be other high polymer concrete besides the polyurethane concrete. The conveying belt 10 of the embodiment is supported on the traveling mechanism 2, and the distributing mechanism 5 has a distributing bin 51, and a left-right rotationally symmetrical distributing auger 52 is arranged in the distributing bin 51. The distributing bin 51 is preferably a closed distributing bin, and the distributing auger 52 stirs the mixture in the distributing bin 51 and can control the rotation direction as needed. In this way, the structure of placing the distributing auger 52 completely in the peripherally closed distributing bin 51 can ensure that the mixture is directly stirred and spread when fed into the distributing bin 51, and ensures that the mixture does not coagulate during the spreading process. In addition, a material level sensing device is arranged in the distributing bin 51 to continuously monitor the position of the mixture, and after real-time data acquisition to the control system, the speed of the conveying belt 10 and the distributing auger 52 is automatically steplessly adjusted, so as to achieve the effect of uniform, stable and continuous feeding, and avoid the segregation of the mixture caused by sudden change of the rotation speed of the auger, and the system has high working stability.

[0027] The smoothing mechanism 6 is arranged after the distributing mechanism 5, the smoothing plate of the smoothing mechanism 6 forms an elevation angle with the horizontal plane and the elevation angle is adjustable, a plurality of vibrators are arranged on the smoothing plate, and the working parameters such as exciting force, vibration frequency and elevation angle can be changed, so as to vibrate and compact the mixture and ensure the paving flatness.

[0028] The spreading mechanism 7 is arranged after the smoothing mechanism 6, and the left and right sides of the platform 1 are each provided with a surface sand bin 11 and a surface sand conveying mechanism 12. The surface sand bin 11 and the surface sand conveying mechanism are both supported on the traveling mechanism 2, the surface sand in the surface sand bin 11 is conveyed to the spreading mechanism 7 through the surface sand conveying mechanism 12. As a preferred embodiment, the surface sand conveying mechanism 12 can adopt a spiral conveying mode to spiral convey the surface sand to the entire spreading mechanism 7, and finally uniformly distribute the surface sand on the pavement, so as to realize the paving of the pavement.

[0029] The spreading mechanism 7 is internally provided with an auger 72, and a material door 71 capable of being independently opened and closed is spaced apart along the width direction of the device.

By controlling the opening and closing of different opening and closing mechanisms 73, the width of the surface sand distribution can be controlled, and by adjusting the opening amplitude of the material door opening and closing mechanism 73, the flow of the spreading can be controlled.

[0030] In addition, a monitoring camera is arranged in each actuator, which is convenient for the operator to monitor and make correct operation in real time; a proportional control technology is adopted to control the working speed of the paver at a constant speed, so as to ensure the stability of the running speed; an automatic deviation correction control technology is adopted to improve the straight line performance of the paver; a CAN bus and a special controller are adopted to realize real-time monitoring of the running state of the device and intelligent diagnosis of faults.

[0031] Taking the polyurethane concrete as the mixed material for paving, the paving and ironing integrated construction equipment drives along the working pavement at a uniform speed through the walking mechanism 2 when working. The conveyor belt 10 delivers the polyurethane concrete to the middle position of the distribution bin 51 of the distribution mechanism 5, and the paving operation is carried out by the left and right rotationally symmetrical distribution auger 52. Then, the polyurethane concrete passes through the ironing mechanism 6, which can improve the compactness of the polyurethane concrete to form a compact and flat pavement structure. At the same time, the surface sand is put into the surface sand bin 11, and then reaches the distribution mechanism 7 through the surface sand conveying mechanism 12 to distribute the surface sand on the compacted polyurethane concrete pavement to enhance the friction and aesthetic of the pavement.
