[0025] Please refer to the attached Figure 6The outer wall of the slide bar 31 is slidably connected to the inside of the outer frame 19. This structural design enables the slide bar 31 to move smoothly along a specific path in the outer frame 19, provides necessary elasticity and support, avoids excessive friction or damage, and thus ensures the smooth operation of the device. The electric heating plate 18 is arranged between the limit plate 29 and the clamping block 30. The function of the limit plate 29 is to provide a fixed position for the electric heating plate 18 to ensure that it does not shift its position during operation.

When the rotating brush head 9 cleans the debris on the ground, the dust collection head and the dust collection plate 11 immediately suck the cleaned dust into the filter system to avoid the flying and pollution of dust in the air.

[0026] Please refer to the attached Figure 8The microprocessor 25 is connected to the displacement sensor 36, the temperature sensor 35, the pressure sensor 22 and the camera 34 through the communication module. The displacement sensor 36 detects the forward position and driving path of the device in real time to ensure that the device is repaired according to the predetermined route. The temperature sensor 35 monitors the temperature of the pit surface in real time and provides temperature feedback for the heating component to ensure the stability of the heating temperature during the repair process.

The camera 34 is responsible for collecting the actual position, size and shape data of the pit, providing accurate image information for the microprocessor to analyze, receiving and processing the signals of the above sensors, and controlling the working status of the cleaning component, spraying component, heating component and compaction component; the microprocessor 25 automatically plans the repair path according to the pit position and size data collected by the camera 34. This path planning can be adjusted in real time to cope with different road conditions and complex shapes of potholes, automatically plan the repair path, and adjust the heating power of the heating component through real-time feedback from the temperature sensor 35; the microprocessor 25 is connected to the remote monitoring terminal to achieve real-time data interaction through the wireless communication module; the remote monitoring terminal is used to display the operating status of the repair device, monitor the working conditions of each component, and provide alarm prompts when an abnormality is detected; the microprocessor 25 has a built-in fault detection module, which can diagnose anomalies in the operation of the device in real time, and optimize the repair operation by adjusting the control algorithm.

[0027] Working principle: When the municipal asphalt road repair device is needed, the user first sets the target position through the control system. After the device is started, the chain drive mechanism drives the crawler walking mechanism to move the device to the specified position. During this process, the displacement sensor is used to detect the moving position in real time. The model of the displacement sensor is: ZLDS100RD. In addition, the camera and image processing module on the upper surface of the vehicle body use machine vision technology to detect the position and size of the potholes in real time to improve the positioning accuracy. Then the motor is started to cooperate with the rotating shaft and bearing to drive the positioning seat and the rotating brush head to rotate to clean the ground. At the same time, the blower inside the self-cleaning air filter will transport the dust raised during cleaning through the dust collection head, dust collection plate and conveying pipe to the inside of the self-cleaning air filter for filtration and discharge, so as to achieve ground cleaning. The cleaning liquid in the cleaning liquid tank is then transported to the inside of the diverter plate through the solenoid valve at the bottom of the cleaning liquid tank, and then discharged to the ground through the nozzles distributed at the bottom of the diverter plate to further clean the pits. Then, the electric heating plate is supplied with electricity through the power supply, so that the electric heating plate generates heat to heat the ground. During this process, the temperature sensor is used to detect the heating condition of the ground in real time. The specific model of the temperature sensor is: TD-3C. The pit surface reaches a suitable construction temperature, and then the asphalt repair can be discharged. Finally, the hydraulic cylinder is started to drive the pressure sensor and the tamping head to move up and down. During this process, the movement of the tamping head is guided by the guide seat, so that the tamping head tamps the ground. At the same time, the compaction effect is monitored in real time through the pressure sensor to ensure that the asphalt mixture is fully compacted. The model of the pressure sensor is: PTG703. In addition, driving the fixing bolt 1 can realize the disassembly and assembly of the positioning seat, so that brushes of different hardness and materials can be selected according to different road conditions. Then, the nozzle can be replaced through the external thread set on the outer wall of the nozzle, so that nozzles with different apertures can be selected according to the viscosity of different detergents, and sealed at the same time with the sealing ring, and then the clamping block is pushed to slide inside the outer frame to shrink the spring. When the clamping block is completely moved to the inside of the outer frame, the electric heating plate can be driven for replacement. During installation, only the electric heating plate needs to be placed in its original position and pushed upward. When the electric heating plate is fitted with the limit plate, the spring is no longer subjected to force to rebound and push the clamping block to move to the lower surface of the electric heating plate, and then the electric heating plate is limited between the limit plate and the clamping block, and then electric heating plates of different powers are selected according to different ambient temperatures. Finally, driving the fixing bolt 2 can realize the fixation and release of the tamping head, and then tamping heads of different shapes and weights are selected according to the characteristics of different asphalt mixtures.
