Description

Technical Field

[0001] The utility model relates to the technical field of road marking, and particularly relates to a road marking paint spraying and marking machine. Background Technique

[0002] Road markings refer to the signs that convey traffic information such as guidance, restriction, and warning to traffic participants on the road with lines, arrows, words, elevation markings, raised road markings, and contour markings. At present, road markings are mostly marked by a paint spraying and marking machine.

[0003] The Chinese patent discloses a multi-component road marking paint spraying and marking machine (the authorization announcement number is CN210684423U). During the process of the marking machine making a straight line on the road, the position of the straight line visual inspection board is parallel to the position of the spray pipe. During continuous marking, continuous comparison and correction are carried out by observing the straight line visual inspection board and the already sprayed route.

[0004] According to the above reference case, the above device uses a straight line visual inspection board to assist the staff in correcting the sprayed marking. Since the above straight line visual inspection board is arranged above the marking in a suspended manner, the staff needs to concentrate the visual field range directly above the two straight line visual inspection boards to be able to carry out visual inspection normally. This requires the center point of the staff's head to coincide with the center point between the two straight line visual inspection boards on the same vertical plane. The staff also needs to pay attention to their feet during walking to prevent stepping on the just-sprayed and not-yet-dry marking, increasing the difficulty of the staff in marking.

[0005] Therefore, a road marking paint spraying and marking machine is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a road marking paint spraying and marking machine to solve the above problems, and it improves the problem that the visual inspection and correction of the existing road marking paint spraying and marking machine with a visual inspection and correction function is relatively difficult.

[0007] The utility model realizes the above purpose through the following technical solutions. A road marking paint spraying and marking machine includes: a trolley, two spraying and marking devices are installed inside the trolley, the bottom of the spraying and marking device penetrates to the outside of the trolley, and a side visual inspection device is slidably connected to the side end of the trolley; a straight line visual inspection device, which is fixedly connected to the pushing end of the trolley.

[0008] Preferably, the straight line visual inspection device includes a slide rail fixedly connected to the pushing end of the trolley. A bidirectional lead screw is rotatably connected inside the slide rail. Threaded sleeves that are slidably connected to the slide rail are threadedly connected to the surfaces of the two opposite threads of the bidirectional lead screw. A vertical visual inspection tube is fixedly connected to the bottom of the threaded sleeve. The center point between the two vertical visual inspection tubes and the axis of one of the spray marking devices are arranged on the same vertical plane. The straight line visual inspection device can adhere to the paint at the inclined part when the marking is inclined, which enables the staff to more accurately detect whether the marking is inclined, so as to reduce the error during visual inspection and facilitate the staff to perform corresponding maintenance operations in a timely manner. At the same time, the staff can adjust the measurement spacing in real time according to the width of the spray marking to meet the measurement requirements of different specifications of markings.

[0009] Preferably, an extended visual inspection strip is slidably connected inside the vertical visual inspection tube. The bottom of the extended visual inspection strip penetrates to the outside of the vertical visual inspection tube. By using a telescopic extended visual inspection strip, it can not only shorten the distance of visual inspection of the marking, but also when the trolley travels on a bumpy road surface, the extended visual inspection strip can fit the road surface and lift and lower accordingly to ensure that the extended visual inspection strip is closely attached to the side of the marking, thereby improving the detection accuracy of the inclination of the marking.

[0010] Preferably, a anti - detachment block fixedly connected to the extended visual inspection strip is slidably connected inside the vertical visual inspection tube. The horizontal cross - sectional length of the contact part between the anti - detachment block and the vertical visual inspection tube is greater than the horizontal cross - sectional length of the contact part between the extended visual inspection strip and the vertical visual inspection tube. This can prevent the extended visual inspection strip from slipping out of the vertical visual inspection tube and reduce the probability of loss of the extended visual inspection strip.

[0011] Preferably, a ball is embedded at the bottom of the extended visual inspection strip, and the center point of the ball is arranged inside the extended visual inspection strip. This can reduce the resistance during the sliding of the extended visual inspection strip on the ground to ensure that the extended visual inspection strip can move normally.

[0012] Preferably, one end of the bidirectional lead screw penetrates to the outside of the slide rail, and a regulating handle is fixedly connected to one end of the bidirectional lead screw. Uniformly distributed anti - slip grooves are formed on the surface of the regulating handle. This enables the staff to more easily and stably adjust the spacing between the two extended visual inspection strips.

[0013] Preferably, uniformly distributed spacing scales are formed on the surface of the slide rail, and an indicating arrow aligned with one of the spacing scales is fixedly connected to the surface of one of the vertical visual inspection tubes. This can assist the staff to more accurately adjust the spacing between the two extended visual inspection strips.

[0014] The beneficial effects of the present utility model are:

[0015] 1. The straight-line visual inspection device can adhere to the paint on the inclined part when the marking line is inclined, which enables the staff to more accurately detect whether the marking line is inclined, so as to reduce the error in the visual inspection process and facilitate the staff to carry out corresponding maintenance operations in a timely manner. At the same time, the staff can adjust the measurement spacing in real time according to the width of the sprayed marking line to meet the measurement requirements of marking lines of different specifications;

[0016] 2. An extendable visual inspection bar is adopted, which can not only shorten the distance of visual inspection of the marking line and further improve the accuracy of detecting the inclination of the marking line, but also when the cart travels on a bumpy road surface, the extendable visual inspection bar can rise and fall in accordance with the road surface to ensure that the extendable visual inspection bar closely adheres to the side of the marking line, thereby improving the accuracy of detecting the inclination of the marking line.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Specifically: As Figures 1-4As shown in the figure, a road marking paint spraying and scribing machine includes: a trolley 1, inside which there are two spraying marking devices 2. The bottom of the spraying marking device 2 penetrates to the outside of the trolley 1, and a side visual inspection device 3 is slidably connected to the side end of the trolley 1; a straight visual inspection device 4, which is fixedly connected to the pushing end of the trolley 1.

[0024] The spraying marking device 2 includes a heating tank, an air compressor and a spray pipe. The heating tank is fixedly connected inside the trolley 1. The air compressor is fixedly connected and communicated with the bottom of the heating tank. The spray pipe is fixedly connected and communicated with the surface of the air compressor. The bottom of the spray pipe penetrates to the outside of the trolley 1. The central axis of one of the spray pipes and the center points between the two vertical visual inspection pipes 404 are all arranged on the same vertical plane.

[0025] The staff needs to pre-add the corresponding paint into the heating tank. The heating tank heats the paint to a liquid state, then the air compressor presses the liquid paint into the spray pipe and sprays it onto the corresponding road surface through the spray pipe. The staff only needs to push the trolley 1 to make the sprayed paint form the corresponding marking.

[0026] A chute is provided on the side of the trolley 1. The side visual inspection device 3 includes a margin visual inspection board slidably connected inside the chute. The top of the margin visual inspection board is provided with uniformly distributed length scales. The above structures are all structures publicly used for measuring the margin in the comparative patent. Since no improvement is made here in this solution, the specific structure, usage method and the effects that can be achieved are the same as those of the comparative patent, and will not be elaborated here.

[0027] Such as Figure 2 、 Figure 3 and Figure 4As shown in the figure, the linear visual inspection device 4 includes a slide rail 401 fixedly connected to the pushing end of the cart 1. Inside the slide rail 401, a bidirectional lead screw 402 is rotatably connected. On the surfaces of the two opposite threads of the bidirectional lead screw 402, there are thread sleeves 403 that are threadedly connected and slidably connected to the slide rail 401. At the bottom of the thread sleeve 403, there is a vertically arranged visual inspection tube 404 fixedly connected. The center point between the two vertically arranged visual inspection tubes 404 and the axis of one of the spray marking devices 2 are arranged on the same vertical plane. Inside the vertically arranged visual inspection tube 404, there is an extended visual inspection strip 405 slidably connected. The bottom of the extended visual inspection strip 405 penetrates to the outside of the vertically arranged visual inspection tube 404. Inside the vertically arranged visual inspection tube 404, there is an anti - detachment block 406 fixedly connected to the extended visual inspection strip 405. The horizontal cross - sectional length of the contact part between the anti - detachment block 406 and the vertically arranged visual inspection tube 404 is greater than the horizontal cross - sectional length of the contact part between the extended visual inspection strip 405 and the vertically arranged visual inspection tube 404. At the bottom of the extended visual inspection strip 405, there is a ball 407 embedded. The center point of the ball 407 is arranged inside the extended visual inspection strip 405. One end of the bidirectional lead screw 402 penetrates to the outside of the slide rail 401, and one end of the bidirectional lead screw 402 is fixedly connected with an adjustment handle 408. On the surface of the adjustment handle 408, there are uniformly distributed resistance - increasing grooves. On the surface of the slide rail 401, there are uniformly distributed spacing scales 409. On the surface of one of the vertically arranged visual inspection tubes 404, there is an indicating arrow 410 fixedly connected and aligned with one of the spacing scales 409.

[0028] When the staff needs to spray markings of different widths, the staff only needs to rotate the adjustment handle 408 in the corresponding direction. The adjustment handle 408 drives the bidirectional lead screw 402 to rotate. The bidirectional lead screw 402 drives the two thread sleeves 403 to move towards or away from each other simultaneously through the two opposite threads. The two thread sleeves 403 drive the two vertically arranged visual inspection tubes 404 to move towards or away from each other. The two vertically arranged visual inspection tubes 404 drive the two extended visual inspection strips 405 to move towards or away from each other until the distance between the two extended visual inspection strips 405 is adjusted to match the width of the marking.

[0029] When the present utility model is in use, when the user normally pushes the spray marking device 2 through the cart 1 to make markings, the cart 1 synchronously drives the linear visual inspection device 4 to move. At this time, the two extended visual inspection strips 405 are symmetrically distributed on both sides of the marking, and the two extended visual inspection strips 405 are in contact with the ground. When the marking is inclined, the surface of the extended visual inspection strip 405 will adhere to the paint. This can enable the staff to more accurately detect whether the marking is inclined, so as to reduce the error in the visual inspection process and facilitate the staff to perform corresponding maintenance operations in a timely manner.

[0030] It should be noted that in the above description, the air compressor and the bidirectional lead screw 402 are both devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the air compressor can be an internal power supply or a mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0031] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
