Description

Technical Field

[0001] The present application relates to the field of urban road surveying and mapping, and in particular to an urban road surveying and marking vehicle for heating solvent-based road marking paint. Background Art

[0002] At present, the surveying work carried out in the planning, design, construction and operation management of urban construction includes urban control surveying, urban topographic mapping, compilation of various thematic maps, construction layout during the construction of municipal engineering projects, and deformation observation of important buildings. In many countries, cadastral surveying is also listed as an important part of urban surveying.

[0003] In addition, in the planning and design of urban construction, urban road surveying and mapping has also become a top priority. In the process of surveying and mapping urban roads, when it is necessary to plan the city's roads, urban road surveying and marking vehicles are often used to complete the depiction of urban road pavement restriction signs. Urban road surveying and marking vehicles have played a huge role in urban planning and highway construction with their advantages of speed, efficiency and accuracy, saving the construction period and economic investment of pavement construction to the greatest extent.

[0004] When marking yellow lines or zebra crossings on urban roads, heated solvent-based road marking paint has become a major material variety, with high solid content, low solvent content, fast drying and good reflective effect. At that time, when using heated solvent-based road marking paint to draw dotted lines, since the spraying needs to be paused to complete the drawing of the intervals between the segments of the dotted lines, the heated solvent-based road marking paint is prone to condensation at the spraying port of the urban road surveying and marking vehicle, thereby affecting the quality of the sprayed dotted lines, which may cause the driver to be unable to quickly and accurately identify the urban road pavement restriction signs, so it needs to be improved. Summary of the invention

[0005] In order to improve the problem in the related art that heated solvent-based road marking paint is easily condensed at the spray nozzle when the urban road surveying and marking vehicle uses heated solvent-based road marking paint to survey and mark dotted lines on urban roads, the present application provides an urban road surveying and marking vehicle using heated solvent-based road marking paint.

[0006] The present application provides a heating solvent-based road marking paint for urban road surveying and marking vehicle using the following technical solutions:

[0007] A city road surveying and marking vehicle for heating solvent-based road marking paint comprises a surveying and mapping bracket, on which a raw material barrel for heating and stirring the heated solvent-based road marking paint is arranged, a spraying port is provided at the bottom of the raw material barrel, an adjusting device is arranged below the spraying port, a driving motor is arranged on the surveying and mapping bracket, an output end of the driving motor is connected to the adjusting device, and the driving motor drives the adjusting device to move below the spraying port.

[0008] By adopting the above technical scheme, when the heated solvent-based road marking paint in the present application is used in the urban road surveying and marking vehicle, the inkjet printing port can continuously discharge material. When it is necessary to draw dotted lines, the inkjet printing port still keeps discharging material. At this time, the driving motor drives the adjusting device to move under the inkjet printing port, so that the adjusting device limits the amount of raw materials in the inkjet printing port. When it is necessary to draw lines, the adjusting device allows the discharge of the inkjet printing port to flow to the road surface. If it is not necessary to draw lines, the discharge of the inkjet printing port is collected for subsequent use. Since the inkjet printing port continuously discharges material, the heated solvent-based road marking paint is not easy to condense at the discharge port, thereby reducing the possibility of affecting the quality of the dotted lines sprayed.

[0009] Optionally, the adjusting device is a rectangular trough structure with a hollow interior, the adjusting device has an opening on one side close to the inkjet port, a limiting plate is provided on the inner side wall of the adjusting device, the limiting plate is arranged parallel to the end wall of the adjusting device, a inkjet hose is provided on one side of the limiting plate, the inkjet hose is connected to the adjusting device, and a return hose is provided on the side of the limiting plate away from the inkjet hose, the return hose is connected to the adjusting device.

[0010] By adopting the above technical scheme, when the regulating device controls the discharge of the inkjet printing port, the position of the regulating device can be changed by driving the motor, that is, when the inkjet printing hose is placed under the inkjet printing port, the heated solvent-based road marking paint can fall onto the road to complete the drawing of the line segment in the dotted line of the urban road; when the reflux hose is placed under the inkjet printing port, the heated solvent-based road marking paint is difficult to fall onto the road to complete the drawing of the blank part in the dotted line of the urban road, thereby reducing the possibility that the solidification of the heated solvent-based road marking paint will affect the quality of the dotted line drawing.

[0011] Optionally, sliding grooves are provided on opposite side walls of the adjusting device, sliding rods are inserted into the sliding grooves, the sliding rods are slidably connected to the sliding grooves, and the sliding rods are connected to the limiting plates.

[0012] By adopting the above technical solution, the structure of the sliding groove and the sliding rod can make the limit plate slide in the horizontal direction in the adjusting device, so that the size of the interface between the return hose and the spray hose can be adjusted to realize the control of the amount of spraying material, thereby completing the adjustment of the line segment length when drawing the dotted line, thereby improving the convenience of the urban road surveying and marking vehicle for heated solvent-based road marking paint in this application when drawing dotted lines of various lengths.

[0013] Optionally, a pushing cylinder is provided in the adjusting device, and an output end of the pushing cylinder is connected to the sliding rod.

[0014] By adopting the above technical solution, the operator can adjust the position of the limit plate by driving the push cylinder. Compared with the operator directly manually adjusting the position of the limit plate, the structure of the push cylinder reduces the possibility of heated solvent-based road marking paint falling on the operator's hands and causing damage to the operator's skin, thereby improving the safety of the system.

[0015] Optionally, a collecting box is provided at one end of the return hose away from the regulating device, and the collecting box is connected to the return hose.

[0016] By adopting the above technical solution, the collection box can collect the excess heated solvent-based road marking paint passing through the return hose, which on the one hand reduces the possibility of the heated solvent-based road marking paint spilling and affecting the environment, and on the other hand allows the heated solvent-based road marking paint to be recycled, reducing the cost of use.

[0017] Optionally, a liquid level detection device is provided on the side wall of the collection box, a pressure detection device is provided on the surveying and mapping bracket, and the pressure detection device is provided at the bottom of the collection box.

[0018] By adopting the above technical scheme, both the liquid level detection device and the pressure detection device can provide feedback on the usage of the internal space of the collection box. By measuring the liquid level in the collection box, the possibility of heated solvent-based road marking paint overflowing from the collection box is reduced. The pressure detection device can provide feedback on the load of the collection box, reducing the possibility of the power of the urban road surveying and marking vehicle being affected due to the excessive weight of the collection box.

[0019] Optionally, one end of the spray hose away from the adjusting device is connected to a spray connector for drawing road markings, and a spray bracket for placing the spray connector is provided on the surveying and mapping bracket. The spray bracket is detachably connected to the spray connector, and the spray connector is detachably connected to the spray hose.

[0020] By adopting the above technical solution, by adopting a structure in which the spraying bracket and the spraying joint are detachably connected, and the spraying joint and the spraying hose are detachably connected, the spraying joint can be replaced according to actual conditions, thereby reducing the possibility that the heated solvent-based road marking paint solidifies on the inner wall of the spraying joint and affects the spraying quality.

[0021] Optionally, a pair of positioning plates are provided on the top of the surveying and mapping bracket, a shift rail is provided on the side wall of the positioning plate, a shift groove is opened on the shift rail, a shift block is inserted in the shift groove, and the shift block is connected to the inkjet printing joint.

[0022] By adopting the above-mentioned technical scheme, the structure of the shift rail and the shift block can enable the spray painting joint to slide under the action of the shift block, so that the spray painting joint can be adjusted during spraying, so as to facilitate the drawing of non-straight lines in the process of urban road surveying and mapping, thereby improving the scope of application of the urban road surveying and marking vehicle in this application.

[0023] Optionally, a shift motor is provided on the shift slide rail, a telescopic structure is provided at the output end of the shift motor, a shift screw is provided at the end of the telescopic structure away from the shift motor, the shift motor drives the shift screw to rotate, a shift sleeve is provided on the shift slide rail, the shift screw is inserted in the shift sleeve, the shift screw is meshed with the shift sleeve, and the end of the shift screw away from the shift motor is rotatably connected to the shift block.

[0024] By adopting the above technical solution, the shift motor can drive the telescopic structure to rotate, so that the telescopic structure drives the shift screw to rotate, so as to adjust the position of the shift block, thereby changing the position of the spray painting joint; and by adjusting the shift screw rotation, the movement range of the spray painting joint can be made finer, thereby improving the accuracy of the urban road surveying and marking vehicle in this application when performing road spray painting.

[0025] Optionally, the telescopic structure includes a telescopic sleeve and a telescopic rod, the telescopic sleeve is connected to the shift motor, the telescopic rod is inserted in the telescopic sleeve, the end of the telescopic rod away from the telescopic sleeve is connected to the shift screw, a locking groove is provided on the inner side wall of the telescopic sleeve, a locking block is provided on the side wall of the telescopic rod, and the locking block is inserted in the locking groove.

[0026] By adopting the above technical solution, the structure of the telescopic sleeve and the telescopic rod can realize the extension and retraction of the overall length. At the same time, the structure of the locking groove and the locking block reduces the possibility of relative rotation of the telescopic rod inserted in the telescopic sleeve, thereby improving the overall stability of the system.

[0027] In summary, the present application includes at least one of the following beneficial effects:

[0028] 1. The structure of the driving motor and the adjusting device is adopted. When the urban road surveying and marking vehicle for heated solvent-based road marking paint in the present application is in use, the spray nozzle can continuously discharge materials. When it is necessary to draw dotted lines, the spray nozzle still keeps discharging materials. At this time, the driving motor drives the adjusting device to move under the spray nozzle, so that the adjusting device limits the amount of raw materials of the spray nozzle. When it is necessary to draw lines, the adjusting device allows the discharge of the spray nozzle to flow to the road surface. If it is not necessary to draw lines, the discharge of the spray nozzle is collected for subsequent use. Since the spray nozzle continuously discharges materials, the heated solvent-based road marking paint is not easy to condense at the discharge port, which reduces the possibility of affecting the quality of the dotted lines drawn.

[0029] 2. The limit plate structure is adopted. When the regulating device controls the discharge of the printing port, the position of the regulating device can be changed by driving the motor. That is, when the printing hose is placed under the printing port, the heated solvent-based road marking paint can fall on the road to complete the drawing of the line segment in the dotted line of the urban road. When the return hose is placed under the printing port, the heated solvent-based road marking paint is difficult to fall on the road to complete the drawing of the blank part in the dotted line of the urban road, which reduces the possibility that the solidification of the heated solvent-based road marking paint affects the quality of the dotted line drawing;

[0030] 3. A structure of a shift motor and a shift screw is adopted. The shift motor can drive the telescopic structure to rotate, so that the telescopic structure drives the shift screw to rotate, so as to adjust the position of the shift block, thereby changing the position of the spray-painting joint; and by adjusting the shift screw rotation, the movement range of the spray-painting joint can be made finer, thereby improving the accuracy of the urban road surveying and marking vehicle in this application when performing road spray painting.

[0044] The implementation principle of the urban road surveying and marking vehicle for heated solvent-based road marking paint in the embodiment of the present application is as follows: when the urban road surveying and marking vehicle for heated solvent-based road marking paint in the present application is drawing dotted line marks on urban roads, the operator turns on the drive motor 14 so that the drive motor 14 drives the adjustment device 13 to move below the spray port 12.
