DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figures 1 to 10 A paint spraying device for highway maintenance includes a vehicle body 1 and a road monument 12, the road monument 12 is located in front of the vehicle body 1, a handlebar 11 is fixedly installed on the rear side of the upper end of the vehicle body 1, a fixing frame 2 is fixedly installed at the middle position of the upper end of the vehicle body 1, a first hydraulic cylinder 21 is fixedly installed on the upper end of the fixing frame 2 by bolts or welding, the output end of the first hydraulic cylinder 21 faces downward and is fixedly connected with a push rod 22, and the push rod 22 is fixedly installed with a connecting block 31 by bolts or welding after sliding through the upper wall of the fixing frame 2, the left and right sides of the connecting block 31 are slidably connected to the inner wall of the fixing frame 2, and a movable block 3 is fixedly installed on the front surface of the connecting block 31, and the movable block 3 is arranged to penetrate front and back, and the connecting block 31 can be driven to move up and down by starting the first hydraulic cylinder 21, and the connecting block 31 can drive the movable block 3 to move up and down synchronously while moving up and down.

[0039] Storage tanks 38 are fixedly installed on the left and right sides of the upper end of the connecting block 31, and colored paint is stored in the storage tanks 38. The color of the colored paint can be changed according to actual needs (for example, milestones on national highways require red paint, while provincial roads require blue), but it is necessary to ensure that the paint in one of the storage tanks 38 is always white. Delivery pumps 36 are fixedly installed on the left and right sides of the upper end of the movable block 3, and the output end of the storage tank 38 is connected to the input end of the delivery pump 36 through a connecting pipe 37. A first slide rail 32 is fixedly installed on the front side of the upper end surface of the movable block 3, and two groups of electric sliders 33 are slidably installed on the upper end of the first slide rail 32. Electric-controlled nozzles 34 are fixedly installed on the upper ends of the two groups of electric sliders 33. The working end of the electric-controlled nozzle 34 faces the side of the road monument 12, and the input end of the electric-controlled nozzle 34 is connected to the output end of the delivery pump 36 located on the same side thereof through a bellows 35. When the electric slider 33 is running, it can drive the electric-controlled nozzle 34 to move back and forth. Since the bellows 35 has the ability to freely expand and contract, it will not affect the movement of the electric-controlled nozzle 34, so that the electric-controlled nozzle 34 can be used to spray different points.

[0040] The second hydraulic cylinder 4 is fixedly installed on the rear surface of the connecting block 31 by bolts or welding. The output end of the second hydraulic cylinder 4 extends to the inside of the movable block 3 after sliding through the connecting block 31. The output end of the second hydraulic cylinder 4 is located on one side inside the movable block 3 and is rotatably installed with a push plate 41 through a connecting piece. The front end of the push plate 41 is glued with an extrusion block 42, which is made of industrial plasticine and is slidably connected to the inner wall of the movable block 3. By starting the second hydraulic cylinder 4, the extrusion block 42 can be pushed to move inside the movable block 3 through the push plate 41, so that the side surface of the extrusion block 42 close to the road monument 12 is tightly fitted with the road monument 12, so that the extrusion block 42 can fill the font groove on the surface of the road monument 12.

[0041] Two groups of symmetrically arranged second slide rails 43 are fixedly installed on the front side of the lower surface of the movable block 3. The second slide rails 43 are vertically arranged, and an electric control slider 44 is slidably installed on the second slide rails 43. The front ends of the two electric control sliders 44 are commonly fixedly connected with a connecting plate 45. A cutting blade 46 is fixedly installed on the upper end surface of the connecting plate 45. The rear side surface of the cutting blade 46 is fitted with the lower front side of the movable block 3, and the lower front side of the movable block 3 is concave, so that the front side surface of the cutting blade 46 and other surfaces of the front side of the movable block 3 can be located on the same horizontal plane.

[0042] A fan 5 is fixedly installed at the middle position of the upper end of the movable block 3 by bolts or welding, and the working end of the fan 5 faces the side of the road monument 12, and a controller 51 is fixedly installed on the upper end of the fan 5. The controller 51 is used to control the overall operation of the device. A temperature sensor 52 fixedly installed on the upper end surface of the movable block 3 is provided in front of the first slide rail 32. When drying, the fan 5 will sense the temperature of the surface of the road monument 12 in real time through the temperature sensor 52, and then the controller 51 controls the temperature of the hot air blown out by the fan 5 through the temperature sensor 52, so as to avoid the situation where the temperature is too low and the paint solidifies too slowly, and the temperature is too high and the paint peels off.

[0043] The specific working principle of the present invention is as follows: when the road monument 12 needs to be maintained, the staff pushes the handlebar 11 to drive the vehicle body 1 to move to the specified position, and then through the controller 51, the controller 51 turns on one of the two delivery pumps 36, and the delivery pump 36 extracts the red (here taking the national highway milestone as an example, the provincial highway is blue) paint used for marking the road monument 12 in the storage tank 38 through the connecting pipe 37, and then the delivery pump 36 delivers the red paint to the bellows 35, so that the red paint enters the electric control nozzle 34 through the bellows 35, and at this time the electric control nozzle 34 is started by the controller 51, so that the electric control nozzle 34 sprays the red paint into the text groove starting on the road monument 12. During the spraying process The controller 51 can be used to start the electric slider 33 fixedly connected to the electric-controlled nozzle 34 that is in the spraying operation, so that the electric slider 33 slides along the first slide rail 32 and drives the electric-controlled nozzle 34 to move synchronously. At the same time, the first hydraulic cylinder 21 drives the push rod 22 to move upward, and the push rod 22 drives the connecting block 31 to slide along the inner wall of the fixed frame 2. The sliding of the connecting block 31 will drive the movable block 3 to move synchronously, and then the electric-controlled nozzle 34 will move synchronously when the push rod 22 moves upward, so that the electric-controlled nozzle 34 can pre-adjust the spraying position when spraying the text groove on the road sign 12, so as to achieve precise spraying of the text groove on the road sign 12, thereby reducing the red paint sprayed to the part outside the text groove.

[0044] When the red paint in the text groove on the road monument 12 is solidified, the construction personnel push the vehicle body 1 to drive the movable block 3 to fit with the road monument 12, and align the port of the movable block 3 with the text groove on the road monument 12. At this time, the second hydraulic cylinder 4 is started, so that the second hydraulic cylinder 4 drives the push plate 41 to move, so that the push plate 41 slides from the inside to the outside along the inner wall of the movable block 3. The sliding of the movable block 3 will generate a thrust on the extrusion block 42, so that the extrusion block 42 will slide along the inner wall of the movable block 3 until the extrusion block 42 fits with the outer wall of the road monument 12. At this time, the second hydraulic cylinder 4 is continued to be started, so that the extrusion block 42 is squeezed into the text groove on the road monument 12 under the action of the push plate 41. When the extrusion block 42 completely fills the text groove on the road monument 12, the electric control slider 44 is started, so that the electric control slider 44 slides upward along the second slide rail 43. The sliding of the electric control slider 44 will drive the connecting plate 45 to move synchronously, so that the connecting plate 45 drives the cutting blade 46 Movement, so that the cutting blade 46 moves upward along the inner wall of the movable block 3, at this time the cutting blade 46 will contact the extrusion block 42, so that the cutting blade 46 cuts the extrusion block 42, at this time the cutting blade 46 will separate the extrusion block 42 in the text groove from the extrusion block 42 in the movable block 3, when the separation is completed, the construction personnel will pull the vehicle body 1 backward, at this time start another set of delivery pumps 36, so that the delivery pumps 36 deliver the white paint to the electric control nozzle 34, at this time start the electric control nozzle 34 to spray the white paint onto the surface of the road monument 12, and because the extrusion block 42 previously filled the text groove on the road monument 12, the electric control nozzle 34 will not spray the white paint into the text groove when spraying the white paint onto the surface of the road monument 12, after the white paint is sprayed and solidified, only the extrusion block 42 in the text groove needs to be taken out to complete the maintenance of the road monument 12, so that the device can spray and maintain text grooves of different shapes on the road monument 12.

[0045] After the electric nozzle 34 has sprayed the paint, the fan 5 is started through the controller 51, so that the fan 5 sprays hot air to the surface of the road monument 12 that has been sprayed with paint, and then the hot air takes away the moisture in the paint, thereby improving the drying efficiency of the paint. At the same time, the fan 5 will sense the temperature of the surface of the road monument 12 in real time through the temperature sensor 52 during drying, and then the controller 51 controls the temperature of the hot air blown out by the fan 5 through the temperature sensor 52 to avoid the situation where the temperature is too low and the paint solidifies too slowly, and the temperature is too high and the paint peels off, thereby ensuring the maintenance efficiency of the road monument 12 while improving the service life of the road monument 12.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
