Description

Technical Field

[0001] This utility model relates to the field of line marking machine technology, specifically a line marking machine for municipal roads. Background Technology

[0002] Road marking devices refer to markings on the road surface that use lines, arrows, text, vertical markings, raised pavement markers, and delineators to convey traffic information such as guidance, restrictions, and warnings to road users. Their function is to regulate and guide traffic. They can be used in conjunction with signs or used alone. A Chinese utility model patent (publication number: CN220202423U) discloses a road marking spraying device that can slide and adjust the vertical plate according to the height of the curbstone. Then, the distance between the material bucket and the curbstone can be adjusted by sliding the telescopic locking ring on the side ruler. This facilitates alignment with the side of the road, improves the convenience of operation and the accuracy of marking.

[0003] However, the aforementioned device still has some shortcomings in use: In actual use, the roller angle in the existing technology is not easily adjustable; the device can only be used with rectangular curb stones to improve the accuracy of line marking, but in real-world situations, such as... Figure 1 As shown, some road curbs have a trapezoidal structure, which makes it difficult for the rollers at different positions on the wheel plate in the existing technology to effectively cooperate with the trapezoidal curbs when they are synchronously raised and lowered and moved horizontally, thus reducing the practicality of the device. Therefore, a road marking machine for municipal roads is proposed to address the above situation. Utility Model Content

[0008] Furthermore, a row of through holes is vertically opened on the fixing block, the mounting frame is a rectangular frame structure, the mounting frame has bolt holes, when the mounting frame slides on the fixing block, the bolt holes are threaded with fastening bolts, and the fastening bolts pass through the threaded holes and engage with the through holes.

[0009] Furthermore, a perforated plate is fixed on the mounting frame. There are two perforated plates, and a rotating shaft is rotatably connected to the two perforated plates. A positioning hole is opened on the outer wall of one end of the rotating shaft that passes through the perforated plate. There are two positioning holes, and the included angle between the two positioning holes is 90°.

[0010] Furthermore, a positioning block is fixed to the outer wall of the perforated plate. A circular hole is provided on the positioning block, and the circular hole is clearance-fitted with the rotating shaft. A first screw hole is provided on the top of the positioning block, which is connected to the circular hole.

The bottom of the mounting plate 10 is provided with a first roller 12, and the bottom of the extension plate 8 is hinged with an electric push rod 13. The moving end of the electric push rod 13 is hinged to one end of the top of the mounting plate 10.

[0029] In this embodiment, when in use, the staff first moves the device to the side of the road. According to the shape of the curbstone, the angle of the first roller 12 can be adjusted. That is, the power supply and switch of the electric push rod 13 are turned on. Through the operation of the moving end of the electric push rod 13, the mounting plate 10 can be pushed to rotate on the fixed rod 9, so that the first roller 12 tilts and rolls with the inclined surface of the curbstone. This improves the convenience and accuracy of the line marking operation, while also improving the applicability of the device.

[0030] Specifically, a row of through holes is vertically opened on the fixing block 2, the mounting frame 3 is a rectangular frame structure, the mounting frame 3 has bolt holes, when the mounting frame 3 slides on the fixing block 2, the bolt holes are threaded with fastening bolts, and the fastening bolts pass through the threaded holes and engage with the through holes.

[0031] The height of the mounting frame 3 can be adjusted by using the fastening bolts and the through holes at different positions on the fixing block 2. In other words, the height of the extension plate 8 can be adjusted according to actual usage requirements.

[0032] Specifically, a perforated plate 4 is fixed on the mounting frame 3. There are two perforated plates 4. A rotating shaft 5 is rotatably connected to the two perforated plates 4.
