[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 4 and Figure 5The utility model provides an embodiment: a road pavement cutting device based on urban traffic engineering, comprising a vehicle body 1, a mounting frame 5 is fixedly connected to the left side of the vehicle body 1, a horizontal plate 6 is fixedly connected to the outside of the mounting frame 5, an electric push rod 7 is fixedly connected to the middle of the horizontal plate 6, an L-shaped plate 8 is fixedly connected to the output end of the electric push rod 7, a motor 9 is fixedly connected to the inside of the L-shaped plate 8, a protective shell 20 is fixedly connected to the outside of the L-shaped plate 8, a mounting ring 10 is fixedly connected to the output end of the motor 9, a connecting column 11 is inserted into the inside of the mounting ring 10, a cutting blade 19 is fixedly connected to the outside of the connecting column 11, a mounting block 13 is fixedly connected to the inside of the mounting ring 10, and the mounting block 13 A moving block 14 is slidably connected inside, a moving rod 16 is fixedly connected to the upper part of the moving block 14, a latch 15 is fixedly connected to the lower part of the moving block 14, a spring 17 is sleeved on the outside of the moving rod 16, a handle 18 is fixedly connected to the top of the moving rod 16, a cooling component 21 is arranged on the upper right side of the vehicle body 1, a protective shell 20 is fixedly connected to the outer right side of the L-shaped plate 8, and the protective shell 20 is arranged on the upper part of the cutting blade 19, a socket 12 is opened inside the connecting column 11, and the latch 15 is plugged into the socket 12, a cross bar 3 is fixedly connected to the outer right side of the vehicle body 1, and a handrail 4 is fixedly connected to the outside of the cross bar 3, and rollers 2 are installed all around the outside of the vehicle body 1.

[0026] When the cutting blade 19 needs to be replaced, the handle 18 is pulled to drive the movement of the lower fixed moving rod 16 connected thereto. As the moving rod 16 is displaced, the moving block 14 fixed at the lower part thereof also moves accordingly, and the movement of the moving block 14 moves the lower fixed latch 15 together. During the movement process, the latch 15 interacts with the spring 17 sleeved on the outside of the moving rod 16. When the spring 17 is squeezed, it will deform, thereby storing a certain amount of potential energy. When the latch 15 is completely separated from the inside of the socket 12, the connecting column 11 and the cutting blade 19 can be easily taken out from the inside of the mounting ring 10 for replacement. When installing a new cutting blade 19, the user only needs to insert the connecting column 11 fixed inside the cutting blade 19 into the inside of the mounting ring 10. At this point, no additional operations are required, and the installation process can be completed by simply loosening the handle 18. Under the reaction force of the spring 17, the pin 15 will automatically insert into the inside of the socket 12, thereby ensuring the stable installation of the cutting blade 19, making it easy to install and disassemble the cutting blade 19. Different from the traditional method of removing the bolts and nuts installed on the outside of the cutting blade by using tools (such as a screwdriver or a wrench), this method is simple and convenient to operate, saving time and effort.

[0027] Reference Figure 1 , Figure 2 and Figure 3The cooling component 21 includes a water pump 2101, which is fixedly connected to the upper right side of the vehicle body 1, and an input end of the water pump 2101 is fixedly connected to one end of a connecting pipe 2102, and a water tank 2103 is fixedly connected to the upper right side of the vehicle body 1, and the other end of the connecting pipe 2102 is fixedly connected to the inside of the water tank 2103, and an output end of the water pump 2101 is fixedly connected to one end of a delivery pipe 2104, and the other end of the delivery pipe 2104 is fixedly connected to a nozzle 2105, and both sides of the outside of the nozzle 2105 are fixedly connected to one end of a mounting rod 22, and the other ends of the two mounting rods 22 are fixedly connected to the outside of the protective shell 20, and a fixing ring 24 is fixedly connected to the middle of the mounting frame 5, and the delivery pipe 2104 runs through the inside of the fixing ring 24, and a filling port 23 is fixedly connected to the upper part of the water tank 2103.

[0028] In actual operation, when the cutting blade 19 generates heat after working for a period of time and needs to be cooled, first, the water pump 2101 is started. Next, the connecting pipe 2102 plays a key role. It connects the water storage tank 2103 and the water pump 2101, so that the cooling water can be smoothly drawn from the water storage tank 2103. The delivery pipe 2104 is responsible for guiding the cooling water from the connecting pipe 2102 to the nozzle 2105. The nozzle 2105 ensures that the cooling water can be evenly sprayed on the cutting blade 19. In this way, the heat on the cutting blade 19 can be quickly taken away, thereby achieving a cooling effect, making it easy to cool the cutting blade 19. Cooling can reduce the thermal damage and wear of the blade, thereby extending the service life of the blade.

[0029] Working principle: When the cutting blade 19 needs to be replaced, the handle 18 is pulled to move the moving rod 16 fixed at the bottom, and the moving rod 16 moves to move the moving block 14 fixed at the bottom, and the moving block 14 moves to move the pin 15 fixed at the bottom. When the moving block 14 moves with the pin 15, the spring 17 sleeved on the outside of the moving rod 16 is squeezed to deform the spring 17 under force. Then, when the pin 15 is separated from the inside of the socket 12, the connecting column 11 and the cutting blade 19 can be taken out from the inside of the mounting ring 10 for replacement. When installing, the connecting column 11 fixed inside the cutting blade 19 can be inserted into the inside of the mounting ring 10, and then the handle 18 is released. When the spring 17 is reversed, the connecting column 11 and the cutting blade 19 are removed from the mounting ring 10. Under the action of force, the pin 15 can be inserted into the inside of the socket 12, which makes it easy to install and disassemble the cutting blade 19. Different from the traditional method of removing the bolts and nuts installed on the outside of the cutting blade by using tools (such as a screwdriver or a wrench), this method is simple and convenient to operate, saving time and effort. Then, when the cutting blade 19 needs to be cooled, the water pump 2101 is started, and the cooling water is pumped out from the inside of the water tank 2103 through the connecting pipe 2102, and then transported through the delivery pipe 2104, and finally sprayed through the nozzle 2105 to cool the cutting blade 19, which makes it easy to cool the cutting blade 19. Cooling can reduce thermal damage and wear of the blade, thereby extending the service life of the blade.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
