[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 5 As shown, the technical solution adopted by the utility model is as follows: a road and bridge marking device, comprising a main bracket 1, a spraying component 3 installed at the lower end of the main bracket 1 through an adjusting component 2, and a left baffle 4 and a right baffle 5 installed on both sides of the main bracket 1 and capable of covering the paint sprayed by the spraying component 3 in the width direction; the adjusting component 2 drives the spraying component 3 and the left baffle 4 and the right baffle 5 to move synchronously, change the position of the spraying component 3, and synchronously adjust the distance between the left baffle 4 and the right baffle 5, thereby adjusting the marking width.

[0025] The main bracket 1 also has integrally formed attachment lugs, which allow the device to be mounted on a locomotive and driven by the locomotive to perform marking operations. The distance between the left and right shields 4, 5 defines the width of the marking. The desired marking width is determined by adjusting the distance between the left and right shields 4, 5, while simultaneously adjusting the position of the spray assembly 3 between the left and right shields 4, 5 to allow spray marking to proceed.

[0026] In this embodiment, the adjustment assembly 2 includes a first mounting member 21 , a second mounting member 22 , a first fixing member 23 , a second fixing member 24 , an adjustment drive motor 25 , and a threaded rod 26 and a guide rod 27 arranged side by side.

[0027] Among them, the first mounting member 21 and the first fixing member 23 are located on the left side of the threaded rod 26 and the guide rod 27, and the first mounting rod and the first fixing member 23 are both installed with a threaded sleeve and a linear bearing seat that are compatible with the threaded rod 26; the second mounting member 22 and the second fixing member 24 are located on the right side of the threaded rod 26 and the guide rod 27, and the second mounting rod and the second fixing member 24 are both installed with a threaded sleeve and a linear bearing seat that are compatible with the threaded rod 26, wherein the threaded sleeve and the linear bearing seat are both existing technologies, and the threaded matching of the threaded sleeve and the threaded rod 26, and the guide matching of the linear bearing seat and the guide rod 27 are both existing technologies, and the matching process will not be described in detail in this embodiment.

[0028] It should be noted that the adjustment drive motor 25 is bolted to the main bracket 1, and one end of the threaded rod 26 is coaxially mounted on the output shaft of the adjustment drive motor 25 via a coupling. The threads on the two ends of the threaded rod 26 are arranged in opposite directions. When the adjustment drive motor 25 drives the threaded rod 26 to rotate, the first mounting member 21, the first fixing member 23, the second mounting member 22, and the second fixing member 24 move synchronously, with the first mounting member 21 and the first fixing member 23 moving in the same direction, and the second mounting member 22 and the second fixing member 24 moving in the same direction. The first mounting member 21 and the first fixing member 23 move synchronously with the second mounting member 22 and the second fixing member 24, either toward or away from each other.

[0029] In this embodiment, the spray assembly 3 includes a first spray element 31 and a second spray element 32. The first spray element 31 is mounted on the first fixing member 23, and the second spray element 32 is mounted on the second fixing member 24. The left shield 4 is mounted on the first mounting member 21, and the right shield 5 is mounted on the second mounting member 22. When the drive motor 25 is adjusted to rotate the threaded rod 26, the first spray element 31 and the second spray element 32 move toward or away from each other, and the left shield 4 and the right shield 5 move toward or away from each other synchronously. Adjusting the distance between the left shield 4 and the right shield 5 changes the position of the first spray element 31 and the second spray element 32, thereby spraying the marking line.

[0030] In this embodiment, the first spraying element 31 includes a left fixed spraying element 311, a left swinging spraying element 312, and a left swinging motor 313. The left fixed spraying element 311 is fixed to the front end of the first fixing element 23 via bolts, the left swinging motor 313 is mounted on the rear end of the first fixing element 23 via a motor mounting bracket, and the left swinging spraying element 312 is mounted on the output shaft of the left swinging motor 313.

[0031] In this embodiment, the second spraying member 32 includes a right-side fixed spraying member 321, a right-side swinging spraying member 322, and a right-side swinging motor 323. The right-side fixed spraying member 321 is fixed to the front end face of the second fixing member 24 by bolts, the right-side swinging motor 323 is mounted on the rear end face of the second fixing member 24 via a motor mounting bracket, and the right-side swinging spraying member 322 is mounted on the output shaft of the right-side swinging motor 323.

[0032] It should be noted that when in use, the left fixed spray part 311, the left swinging spray part 312, the right fixed spray part 321, and the right swinging spray part 322 are all connected to the paint feeder of the locomotive through hoses. When the left swinging motor 313 drives the left swinging spray part 312 to rotate, the range of paint sprayed on the ground by the left swinging paint part can be adjusted; when the right swinging motor 323 drives the right swinging spray part 322 to rotate, the range of paint sprayed on the ground by the right swinging paint part can be adjusted.

[0033] The left swing motor 313 and the right swing motor 323 are preferably stepping motors, so that they can accurately control the rotation angles of the corresponding left swing spray parts 312 and right swing spray parts 322, and then accurately adjust the range of paint sprayed on the ground by the left swing spray parts 312 and the right swing spray parts 322.

[0034] In this embodiment, a PLC controller is also installed on the main support 1, and the adjustment drive motor 25, the left swing motor 313, and the right swing motor 323 are all electrically connected to the PLC controller.

[0035] In this embodiment, a left baffle 7 is installed on the left baffle 4, and a right baffle 8 is installed on the right baffle 5. The left baffle 7 and the right baffle 8 are both located below the adjustment component 2.

[0036] The working principle of this device is as follows: When the left-side swinging spraying element 312 and the right-side swinging spraying element 322 are facing vertically downward, the left-side fixed spraying element 311, the left-side swinging spraying element 312, the right-side fixed spraying element 321, and the right-side swinging spraying element 322 maintain the same spraying width on the ground. When the left-side swinging motor 313 drives the left-side swinging spraying element 312 to swing left, or when the right-side swinging motor 323 drives the right-side swinging spraying element 322 to swing right, the spraying angle of the left-side swinging spraying element 312 shifts to the left, and the right-side swinging spraying element 322 shifts to the right. Under the constraints of the left baffle 4 and the right baffle 5, the spraying range of the left-side swinging spraying element 312 on the ground changes, and the spraying range of the right-side swinging spraying element 322 on the ground changes. The specific change process is as follows:

[0037] like Figure 4As shown in the figure, A represents the width range of the ground spraying when the left swing spraying part 312 is in a vertical downward state and the left fixed spraying part 311 is in a vertical downward state, and B represents the width range of the ground spraying when the right swing spraying part 322 is in a vertical downward state and the right fixed spraying part 321 is in a vertical downward state.

[0038] When the adjustment drive motor 25 drives the threaded rod 26 to rotate counterclockwise, the left shield 4, the left swing spraying part 312, and the left fixed spraying part 311 move synchronously to the right, and the right shield 5, the right swing spraying part 322, and the right fixed spraying part 321 move synchronously to the left. Figure 5 As shown, since the left swing spraying part 312 and the left fixed spraying part 311 move to the right, the spraying width range of the left swing spraying part 312 and the left fixed spraying part 311 moves to the right, while the spraying width range of the right swing spraying part 322 and the right fixed spraying part 321 moves to the left, forming an overlapping area as shown in section b in the figure. This can easily lead to the situation that the lines on both sides of the spraying area [i.e. the line width] are not clear, and the middle line wastes too much paint. It should be noted that Figure 4 Corresponding to the middle A section Figure 5 The sum of sections a and b; Figure 4 Middle B section corresponds Figure 5 The sum of sections b and c.

[0039] Therefore, when the left oscillating spraying member 312 moves to the right, the left oscillating motor 313 drives the left oscillating spraying member 312 to rotate clockwise by a specific angle, so that the maximum spraying angle on the right side of the left oscillating spraying member 312 rotates to point G. Due to the obstruction of the left baffle 4, when the left oscillating spraying member 312 rotates clockwise, the excess paint sprayed is limited by the left baffle 4. Similarly, when the right oscillating spraying member 322 moves to the right, the right oscillating motor 323 drives the right oscillating spraying member 322 to rotate clockwise by a specific angle, so that the maximum spraying angle on the left side of the right oscillating spraying member 322 rotates to point F. Due to the obstruction of the right baffle 5, when the right oscillating spraying member 322 rotates clockwise, the excess paint sprayed is limited by the right baffle 5. More preferably, a waste material recovery mechanism can be installed on the left baffle 4 and the right baffle 5 to recover the waste material. This embodiment will not be described in detail.

[0040] 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
