Description

Technical Field

[0001] This invention relates to the field of supporting equipment technology for highway construction, and in particular to a highway marking machine. Background Technology

[0002] A road marking machine is a device that uses paint to apply markings to roads. In use, workers manually or by driving a marking vehicle move along the marked path, and paint is sprayed from the bottom of the nozzle, thus achieving the effect of marking the road. Depending on the material used, some marking machines require a heating mechanism to heat the paint for marking, while others use cold paint directly. Based on the pressure applied, they are divided into atmospheric pressure marking and pressurized marking. Atmospheric pressure marking uses gravity flow to apply paint to the road, while pressurized marking uses pressurized paint tanks or an electric pump to extract paint for marking.

[0003] Although existing road marking machines have the advantage of improving work efficiency compared to manual labor, they still have some specific technical problems due to their structural limitations. For example, Chinese patent number "201921234899.8", patent name "Road Marking Machine", describes that "this utility model solves the problem that existing road marking machines do not have the ability to mix marking materials by setting up a base plate, bracket, pulley, positioning frame, compression pump, first pipe, nozzle, second connecting pipe, discharge pipe, box, motor, first stirring paddle, first gear, second gear, second stirring paddle, feed pipe, heating device, solenoid valve and push handle. 2. This utility model effectively prevents dust and impurities in the air from entering the inner cavity of the box by setting up a pipe cover, protects and limits the motor by setting up a protective box, fixes the box by setting up a reinforcing block, and supports the first pipe by setting up a limit ring and a limit rod." As can be seen from the above, the comparative patent has solved the problem to some extent that existing line marking machines lack the ability to mix line marking materials. However, like all existing line marking machines, when marking long straight lines on highways, there is no constraint device—that is, no device that can guarantee that the drawn lines are as straight as possible. Therefore, relying entirely on manual judgment of line quality is susceptible to variations in the experience of the line marking personnel, resulting in a possibility of lines not being straight. Furthermore, the need for workers to constantly observe the drawn lines is extremely inconvenient. Although laying guide rails can ensure the quality of the lines drawn by the line marking machine, the guide rails are bulky, inconvenient to store and transport, and their length cannot be very long. When marking long lines, workers need to move the rails backward, which not only inconveniences workers but also hinders work efficiency, presenting significant problems in their application. In conclusion, it is particularly necessary to provide a line marking machine that can guarantee the quality of the drawn straight lines, provide convenience for workers, and improve line marking efficiency. Summary of the Invention

[0004] To overcome the shortcomings of existing line marking machines due to structural limitations, as described in the background, this invention provides a line marking machine body that, under the combined action of related mechanisms and circuits, eliminates the need for guide rails or other means to limit the straight lines drawn by the machine body. A simple, compact, easy-to-store, and portable photoelectric switch with a long operating distance determines whether the drawn line is straight. If the drawn line deviates to the left or right, it promptly alerts the worker to correct the orientation, thus providing convenience for the worker, improving line marking efficiency, and ensuring the quality of the drawn straight lines.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A road marking machine includes a marking machine body, characterized by further comprising a detection mechanism and a receiving mechanism; a handle is installed on the side of the vehicle body of the marking machine body; the detection mechanism includes a battery, a charging socket, a power switch, a photoelectric transmitter, and a fixing plate; the photoelectric transmitter has a magnet installed on its housing, and a steel adsorption plate is installed on the side of the fixing plate, with the photoelectric transmitter adsorbed onto the adsorption plate by the magnet; the battery, charging socket, and power switch are installed in the component compartment of the fixing plate; the two terminals of the battery are electrically connected to the power input terminals of the two sets of photoelectric transmitters respectively; the receiving mechanism includes a battery A, a charging socket A, a power switch A, a photoelectric receiver, and a prompting circuit; the housing of the photoelectric receiver is equipped with magnet A, and the photoelectric receiver is adsorbed onto the front of the vehicle body by magnet A, and is in a face-to-face state with the photoelectric transmitter; the battery A, charging socket A, power switch A, and prompting circuit are installed in the component box of the vehicle body; the two terminals of the battery A are electrically connected to the power input terminals of the photoelectric transmitter respectively.

[0007] Furthermore, the paint tank discharge pipe of the marking machine body is connected to the liquid inlet pipe of the electric pump of the marking machine body, the liquid outlet pipe of the electric pump is connected to one end of a solenoid valve, and the other end of the solenoid valve is connected to the liquid inlet end of the marking nozzle of the marking machine body.

[0008] Furthermore, the height of the photoelectric transmitter and the height of the photoelectric receiver are the same.

[0009] Furthermore, the prompting circuit includes two buzzers and two flashlights electrically connected to each other. The negative power input terminals of the two flashlights and the two buzzers are connected. The positive power input terminal of the first flashlight and the first buzzer are connected. The positive power input terminal of the second flashlight and the second buzzer are connected.

[0010] Furthermore, there are two sets of photoelectric receivers, and the power output terminals of the two sets of photoelectric receivers are electrically connected to the power input terminals of the first flash lamp, the second flash lamp, etc.

[0011] Furthermore, the two sets of photoelectric receivers and the two sets of photoelectric transmitters are infrared long-distance transceiver modules. When the receiving surfaces of the two sets of photoelectric receivers receive the infrared beams emitted in a straight line from the two sets of photoelectric transmitters, the signal output terminals output a low level, and when no infrared beams are received, the signal output terminals output a high level.

[0012] Furthermore, the battery and battery A can also be replaced by an AC-to-DC switching power supply module.

[0013] Furthermore, the two flashlights and buzzers emit different colors and have different alarm sounds.

[0014] The beneficial effects of this invention are as follows: This invention is particularly advantageous when used for marking straight lines on highways. When marking lines, the detection mechanism is placed at the beginning of the marking point, and then the vehicle body is gradually moved and the line is drawn. During the marking process, when the vehicle body does not deviate to the left or right, that is, when the drawn line is straight, neither of the two flashlights nor the buzzer will be powered on. When the vehicle body deviates to the left or right due to uneven road surface or operator error, that is, when the drawn line is no longer straight, the infrared beam emitted by one or two sets of photoelectric transmitters will no longer be received by one or two sets of photoelectric receivers. Consequently, one or two flashlights and the buzzer will be powered on. In this way, the operator can adjust the vehicle's position to align with the detection mechanism in a timely manner, and one or two flashlights and the buzzer will stop working due to power loss. As described above, this invention eliminates the need for guide rails or other means to limit the straight lines drawn by the marking machine. It utilizes a simple, compact, and easily stored and carried photoelectric switch with a long operating distance to determine if the drawn line is straight. If the drawn line deviates to the left or right, it promptly alerts the operator to correct the orientation, thus providing convenience, improving marking efficiency, and ensuring the straight lines are of acceptable quality. In conclusion, this invention has promising application prospects. Attached Figure Description

[0020] Figure 1 , 2As shown in Figures 3 and 4, a road marking machine includes a main body comprising a vehicle body 1, wheels 2, paint cans 3, an electric pump 4, marking nozzles 5, and other necessary components; it also includes a detection mechanism and a receiving mechanism; four wheels 2 are respectively installed around the lower end of the vehicle body 2 via screws and nuts; the lower ends of the paint cans 3 and the electric pump 4 are respectively installed at the upper front end and middle of the vehicle body 1 via screws and nuts; the marking nozzles 5 are located at the lower front end and middle of the vehicle body 1; a handle 6 is welded to the rear end of the vehicle body 1; the detection mechanism includes a battery G2, a charging socket CZ2, a power switch S2, photoelectric transmitters A2 and A3, and a fixing plate 7; there are two sets of photoelectric transmitters, and a rectangular magnet 8 is glued to the front end of the housing of each of the two sets of photoelectric transmitters A2 and A3; a rectangular magnet 8 is glued to the rear end of the fixing plate 8. A steel adsorption plate is used, and two sets of photoelectric transmitters A2 and A3 are adsorbed onto the adsorption plate by magnets 8. The battery G2, charging socket CZ2, and power switch S2 are installed in the component compartment at the lower end of the fixed plate 7. The receiving mechanism includes a battery AG1, a charging socket ACZ1, a power switch AS1, photoelectric receivers A and A1, and a prompting circuit 9. There are two sets of photoelectric receivers. A rectangular magnet A10 is glued to the rear end of the housing of each of the two sets of photoelectric receivers A and A1. A steel adsorption plate A is glued to the front end of the vehicle body 1. The two sets of photoelectric receivers A and A1 are adsorbed onto the adsorption plate A by magnets A10. The battery AG1, charging socket ACZ1, power switch AS1, and prompting circuit 9 are installed on the circuit board in the component box 11 at the rear end of the vehicle body.

[0021] Figure 1 , 2As shown in Figures 3 and 4, the discharge pipe at the lower end of the paint tank 3 and the inlet pipe of the electric pump 4 are connected by a pipe. The discharge pipe of the electric pump 4 and one end of a solenoid valve (not shown in the figure) are connected by a pipe. The other end of the solenoid valve and the inlet of the marking nozzle 5 are connected by a pipe. The solenoid valve is connected to the two poles of the battery AG1 via a power switch KD installed on the upper side of the handle. The left and right distances and ground heights of the two sets of photoelectric transmitters A2 and A3 are the same as those of the two sets of photoelectric receivers A and A1. The prompting circuit includes buzzers B and B1 and flashlights H and H1 connected by circuit board wiring. The negative power input terminals of the two flashlights H and H1 and the two buzzers B and B1 are connected. The positive power input terminals of the first flashlight H and the first buzzer B are connected. The positive power input terminals of the second flashlight H1 and the second buzzer B1 are connected. The power output pins 3 of the two photoelectric receivers A and A1 are connected to the power input pins of the first flash lamp H and the second flash lamp H1, respectively. The two photoelectric receivers A and A1, and the two photoelectric transmitters A2 and A3, are finished infrared long-range transceiver modules. When the receiving surfaces of the two photoelectric receivers A and A1 receive the infrared beams emitted directly from the two photoelectric transmitters A2 and A3, respectively, pin 3 of the signal output terminal outputs a low level; when no infrared beam is received, pin 3 of the signal output terminal outputs a high level. Batteries G2 and AG1 can also be replaced by AC-to-DC switching power supply modules. The two flash lamps H and H1, and the buzzers B and B1 have different light colors and alarm sounds.

[0022] Figure 1 , 2 As shown in Figures 3 and 4, the two terminals of battery G2 (24V / 10Ah) and the two ends of charging socket CZ2 (the power charger plug is inserted into charging socket CZ2 to charge battery G2) are connected by wires. The positive terminal of battery G2 is connected to one end of power switch S1 by wire. The other end of power switch S1, the negative terminal of battery G2, and the power input terminals 1 and 2 of the two sets of photoelectric transmitters A2 and A3 are connected by wires. The two terminals of battery AG1 (24V / 100Ah) and the two ends of charging socket ACZ1 are connected by wires (the power charger plug is inserted into charging socket CZ1 to charge battery AG1). The positive terminal of battery AG1 is connected to one end of power switch AS1 by wire. The other end of power switch AS1, the negative terminal of battery AG1, and the power input terminals 1 and 2 of the two sets of photoelectric receivers A and A1 are connected by wire.

[0023] Figure 1 , 2As shown in Figures 3 and 4, this invention is particularly advantageous for use in marking straight lines on highways. When marking lines, the detection mechanism is placed at the beginning of the marking point. Then, the appropriate spacing and height of the two sets of photoelectric transmitters A2 and A3 in front of the adsorption plate are adjusted left and right, and up and down. Due to the adsorption by magnet 8, the adjustment is more convenient. After adjustment, the distance between the inner ends of the two sets of photoelectric transmitters A2 and A3 is slightly less than the width of the line to be marked. Next, the operator moves the vehicle body about 50 cm away from the detection mechanism and manually adjusts the appropriate spacing and height of the two sets of photoelectric receivers A and A1 in front of the vehicle body, left and right, and up and down. Due to the adsorption by magnet A10, the adjustment is more convenient. After adjustment, the distance between the inner ends of the two sets of photoelectric receivers A and A1 is slightly less than the width of the line to be marked, and the two sets of photoelectric receivers A and A1 and the two sets of photoelectric transmitters A2 and A3 are respectively in a straight line. Then, the power switches S1 and S2 are turned on to begin the marking operation. After the staff turns on the power switch KD of the solenoid valve and the power switch of the electric pump 4, the electric pump 4 draws out the paint from the paint tank 3, pressurizes it, and sprays it out from the marking nozzle 5 onto the road. Since the staff pulls the vehicle forward by the handle 6, a straight line will be drawn at the corresponding position on the road.

[0024] Figure 1 , 2As shown in Figures 3 and 4, when the vehicle is moving forward and does not deviate left or right (i.e., the drawn line is straight), the receiving surfaces of the two photoelectric receivers A and A1 respectively receive the infrared beams emitted by the two photoelectric transmitters A2 and A3 in a straight line, and pin 3 of the signal output terminal outputs a low level. During the line marking process, when the vehicle deviates left or right due to uneven road surface or operator error (i.e., the drawn line is no longer straight), the infrared beams emitted by one or both photoelectric transmitters A2 and A3 are no longer received by one or both photoelectric receivers A and A1. Consequently, pin 3 of the signal output terminal of one or both photoelectric receivers A or A1 will output a high level, which enters the power input terminal of buzzer B and flash lamp H, or buzzer B1 and flash lamp H1. Thus, buzzer B and flash lamp H, or buzzer B1 and flash lamp H1, are energized respectively or together. When powered on, the machine operates automatically. This allows workers to adjust the vehicle's position to align with the detection mechanism based on prompts. When one or two flashlights and buzzers lose power, the machine stops working, and workers can resume normal line marking by pulling the vehicle forward. (When buzzer B and flashlight H are powered on, it indicates the vehicle is deviating to the left; workers adjust the vehicle to the right. When buzzer B1 and flashlight H1 are powered on, it indicates the vehicle is deviating to the right; workers adjust the vehicle to the left. In practice, because the receiving surfaces of the two photoelectric receivers A or A1 have convex lenses, they can effectively receive infrared beams.) Through this invention, there is no need to lay guide rails or other means to limit the straight lines drawn by the marking machine. The simple, compact, and easily stored and carried photoelectric switch with a long operating distance determines whether the drawn line is straight. When the drawn line deviates to the left or right, it promptly prompts workers to correct the orientation, thus providing convenience, improving marking efficiency, and ensuring the drawn lines are of acceptable quality. Figure 4 In the middle, the flashlights H and H1 operate at 24V and have a power of 5W, and are red and green flashlights respectively; the buzzers B and B1 are SSF-24V active continuous sound buzzer alarm products; the photoelectric receivers A and A1 and the photoelectric transmitters A2 and A3 are infrared transmitting and receiving through-beam photoelectric switches products, with an operating voltage of DC 24V.
