[0002] With the increase in urban traffic volume, the traffic management department has achieved good results by optimizing the channelization configuration of intersections, increasing vehicle lanes while keeping the road surface width unchanged, and effectively diverting vehicles. However, the coexistence of original markings and newly marked markings on the road often confuses drivers. It is necessary to remove the original markings, re-plan and re-mark the markings, and improve the traffic rate at the intersection.

[0003] For example, patent No. CN218322265U discloses a road marking removal device, including a traveling vehicle, a chassis is installed on the top of the traveling vehicle, two groups of adjustment mechanisms are installed on the top of the interior of the chassis, a cleaning mechanism and a grinding mechanism are respectively arranged at the bottom ends of the two groups of adjustment mechanisms, and channels corresponding to the cleaning mechanism and the grinding mechanism are opened on the traveling vehicle; the grinding mechanism includes a second housing, a second motor is arranged inside the second housing, the output end of the second motor is connected to multiple groups of rotating shafts through a planetary gear mechanism, the rotating shafts are rotatably connected to the bottom end of the second housing, the bottom end of the rotating shafts extends to the outside of the bottom end of the second housing and is installed with a grinding disc; a bucket plate is installed on the side wall of the second housing, and a second dust suction nozzle is installed on the bucket plate; a dust suction device is arranged on one side of the top of the housing, the dust suction device is connected to a three-way pipe through a dust suction main pipe, the three-way pipe is located inside the housing, dust suction auxiliary pipes are installed at both ends of the three-way pipe, and the other ends of the dust suction auxiliary pipes on the left and right sides are respectively connected to the cleaning mechanism and the grinding mechanism.

[0004] Although the above scheme can grind and remove the road markings, the grinding disc is driven by the electric telescopic rod to move toward the road markings, which may easily cause excessive grinding depth and cause groove damage to the road surface. Summary of the invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a road marking removal device, which can remove road markings on a road surface without causing groove damage to the road surface.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A road marking removal device, comprising:

[0008] A cleaning roller, wherein teeth are evenly distributed on the circumference of the cleaning roller;

[0009] Two symmetrically arranged pillars, a first window is opened in the middle of the pillars, a limit block is fixedly connected in the first window, a first slider is slidably connected in the first window at the lower end of the pillar, a first slide bar is fixedly connected at the upper end of the first slide bar, a first spring is sleeved on the first slide bar, and the upper end of the first slide bar passes through the limit block and is slidably connected thereto;

[0011] A guide wheel is rotatably connected to the bottom end of the support column.

[0012] The above technical solution, its principle and technical effect:

[0013] When in use, adjust the two pillars to move downward so that the guide wheel contacts the road surface, and the two guide wheels are located on both sides of the road marking, the peripheral teeth of the cleaning roller contact the upper surface of the road marking, the first spring is always in a compressed state, and the transmission mechanism is driven by the driving source to drive the first sprocket to rotate, thereby driving the cleaning roller to rotate, and the road marking is polished and removed. Since the road marking is attached to the road surface and its thickness is higher than the road surface, as the cleaning roller polishes, the first slider moves downward continuously under the elastic force of the first spring, so that the cleaning roller polishes the road marking while moving downward until the first slider stops moving. At this time, the teeth at the lowest point of the cleaning roller remain in a horizontal plane with the road surface and no longer move downward, so that the road surface will not be polished into grooves. At the same time, moving back and forth along the road marking can thoroughly clear the marking without causing groove damage to the road surface.

[0014] Furthermore, a first slide groove is provided on the inner side surface of the first window at the lower end of the pillar in the vertical direction, and first protrusions extending outwardly on both sides of the first sliding block are slidably connected in the first slide groove.

[0015] Furthermore, the upper ends of the two pillars pass through the horizontal plate and are slidably connected to the horizontal plate. A connecting plate is fixedly connected between the two pillars located at the upper ends of the horizontal plate. A motor is fixedly connected to the upper end of the connecting plate. A second sprocket is fixedly connected to the output end of the motor. A chain is meshed and connected between the second sprocket and the first sprocket.

[0016] Furthermore, a third window is provided on the transverse plate at the location of the chain, and the chain passes through the third window.

[0018] Furthermore, a second slide groove is transversely formed on the inner side surface of the second window on the slide rail member, and a second protrusion extending outward from the side surface of the second sliding block is slidably connected in the second slide groove.

[0019] Furthermore, a blocking piece is fixedly connected to the end of the second slide rod, and the second spring is arranged on the outside of the slide rail member, with one end of the second spring being closely adjacent to the slide rail member and the other end being closely adjacent to the blocking piece.

[0020] Furthermore, the top ends of the two pillars are fixedly connected with a cross fixing plate, one side of the cross fixing plate is threadedly connected with a threaded rod, the lower end of the threaded rod is rotatably connected with a connecting block, and the connecting block is fixedly connected to the upper surface of the cross plate.

[0021] A guide column is slidably connected to the other side of the cross fixing plate, and the lower end of the guide column is fixedly connected to the cross plate.

[0022] Furthermore, a hand piece is fixedly connected to the top end of the threaded rod.

[0023] Furthermore, a hand push piece is fixedly connected to the end of the transverse plate, and a wheel is fixedly connected to the circumferential side of the lower surface of the transverse plate.

[0024] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0025] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0026] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0027] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0028] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0029] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0030] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0031] Beneficial effects of the present invention:

[0032] It can remove road markings on the road surface without causing groove damage to the road surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0041] According to the concept of this application, Figures 1 to 5 An embodiment of a road marking line removing device is described below. Specifically, the road marking line removing device is constructed as a split structure, which has three components, namely, a removing roller 1 , a support column 2 , and a guide wheel 7 . Through the cooperation of the first slider 3, the first slide bar 4, the first spring 5, the first sprocket 6 and other structures, the two pillars 2 are adjusted to move downward so that the guide wheel 7 contacts the road surface, and the two guide wheels 7 are located on both sides of the road marking, and the peripheral teeth of the cleaning roller 1 contact the upper surface of the road marking. The first spring 5 is always in a compressed state, and the transmission mechanism is driven by the driving source to drive the first sprocket 6 to rotate, and then drive the cleaning roller 1 to rotate, so as to grind and remove the road marking. Since the road marking is attached to the road surface and its thickness is higher than the road surface, as the cleaning roller 1 grinds, the first slider 3 continuously moves downward under the elastic force of the first spring 5, so that the cleaning roller 1 grinds the road marking while moving downward until the first slider 3 stops moving. At this time, the teeth at the lowest point of the cleaning roller 1 remain in a horizontal plane with the road surface and no longer move downward, so that the road surface will not be ground into grooves. At the same time, it moves back and forth along the road marking, so that the marking can be thoroughly removed without causing groove damage to the road surface.

[0042] like Figure 1-5 As shown, a road marking removal device comprises:

[0043] A cleaning roller 1, wherein teeth are evenly distributed on the circumference of the cleaning roller 1;

[0044] Two symmetrically arranged pillars 2, a first window 21 is opened in the middle of the pillars 2, a limit block 22 is fixedly connected in the first window 21, a first slider 3 is slidably connected in the first window 21 at the lower end of the pillar 2, a first slide bar 4 is fixedly connected at the upper end of the first slide bar 3, a first spring 5 is sleeved on the first slide bar 4, and the upper end of the first slide bar 4 passes through the limit block 22 and is slidably connected thereto;

[0045] The cleaning roller 1 is arranged between the two pillars 2, and both ends of the cleaning roller 1 are rotatably connected to the first slider 3, and one end of the cleaning roller 1 passes through the first slider 3 and is fixedly connected to the outwardly extending portion thereof with the first sprocket 6;

[0046] Guide wheel 7, guide wheel 7 is rotatably connected to the bottom end of support column 2.

[0047] When in use, adjust the two pillars 2 to move downward so that the guide wheel 7 contacts the road surface, and the two guide wheels 7 are located on both sides of the road marking, the peripheral teeth of the cleaning roller 1 contact the upper surface of the road marking, the first spring 5 is always in a compressed state, and the transmission mechanism is driven by the driving source to drive the first sprocket 6 to rotate, thereby driving the cleaning roller 1 to rotate, and the road marking is polished and removed. Since the road marking is attached to the road surface, its thickness is higher than the road surface. As the cleaning roller 1 is polished, the first slider 3 continues to move downward under the elastic force of the first spring 5, so that the cleaning roller 1 polishes the road marking while moving downward until the first slider 3 stops moving. At this time, the teeth at the lowest point of the cleaning roller 1 remain in a horizontal plane with the road surface and no longer move downward, so that the road surface will not be polished into grooves. At the same time, it moves back and forth along the road markings, which can thoroughly remove the markings without causing groove damage to the road surface.

[0048] The cleaning roller 1 is mainly used for grinding and removing road markings. In some embodiments, the cleaning roller 1 can also be made into a grinding wheel roller, which is similar to a grinding wheel sheet. A binder is added to the abrasive, and a porous body is made by pressing, drying and baking. However, due to its wear characteristics, it is necessary to replace the severely worn grinding wheel roller.

[0049] The guide wheel 7 is mainly used to provide a limit for the two pillars 2 and reduce the friction with the ground. In some embodiments, the guide wheel 7 can be replaced with a ball, and the ball is embedded in the bottom of the two pillars 2, which can also achieve the effect of rolling with the ground.

[0050] A first slide groove 23 is provided on the inner side of the first window 21 at the lower end of the support 2 in the vertical direction, and first protrusions 31 extending outward on both sides of the first slider 3 are slidably connected in the first slide groove 23. Such a configuration allows the first slider 3 to move up and down without being separated from the first window 21, thereby realizing the downward movement of the cleaning roller 1.

[0051] The upper ends of the two pillars 2 penetrate the transverse plate 8 and are slidably connected to the transverse plate 8. A connecting plate 24 is fixedly connected between the two pillars 2 located at the upper end of the transverse plate 8. A motor 9 is fixedly connected to the upper end of the connecting plate 24. A second sprocket 91 is fixedly connected to the output end of the motor 9. A chain 10 is meshedly connected between the second sprocket 91 and the first sprocket 6. The motor 9, as a driving source, drives the second sprocket 91 to rotate, drives the chain 10 to transmit, and then drives the first sprocket 6 and the cleaning roller 1 to rotate, so as to remove the road markings.

[0052] A third window 81 is provided on the cross plate 8 at the chain 10, and the chain 10 passes through the third window 81. The third window 81 is used for the chain 10 to pass through, and the transmission of the chain 10 is not hindered.

[0053] A slide rail 11 is fixedly connected to the side of the pillar 2 on the same side as the first sprocket 6. A second window 111 is provided in the middle of the slide rail 11. A second slider 12 is slidably connected in the second window 111. A second slide bar 13 is fixedly connected to the second slider 12. The second slide bar 13 penetrates the slide rail 11 and is slidably connected thereto. A second spring 14 is sleeved on the second slide bar 13. A third sprocket 15 is rotatably connected to the side of the second slider 12. The third sprocket 15 is meshed and connected with the chain 10. The third sprocket 15 is a tensioning wheel. The second spring 14 always keeps a compressed state, pulling the second slider 12 outward, thereby causing the third sprocket 15 to have a pulling force outward, pulling the chain 10, and ensuring that the chain 10 always keeps a tensioned state during the up and down movement of the cleaning roller 1, and ensuring that the chain 10 will not be decoupled.

[0054] A second slide groove 112 is formed in the inner side of the second window 111 on the slide rail member 11 in the transverse direction, and a second protrusion 121 extending outward from the side of the second slider 12 is slidably connected in the second slide groove 112. Such an arrangement ensures that the second slider 12 does not separate from the slide rail member 11, and ensures that the third sprocket 15 functions as a tensioning wheel.

[0055] The end of the second slide bar 13 is fixedly connected with a stopper 131, and the second spring 14 is arranged outside the slide rail 11, with one end of the second spring 14 close to the slide rail 11 and the other end close to the stopper 131. Such an arrangement ensures that the second spring 14 does not separate from the second slide bar 13.

[0056] The top ends of the two pillars 2 are fixedly connected with a cross fixing plate 25, one side of the cross fixing plate 25 is threadedly connected with a threaded rod 16, the lower end of the threaded rod 16 is rotatably connected with a connecting block 17, the connecting block 17 is fixedly connected to the upper surface of the cross plate 8, the other side of the cross fixing plate 25 is slidably connected with a guide column 18, the lower end of the guide column 18 is fixedly connected to the cross plate 8. The top end of the threaded rod 16 is fixedly connected with a hand piece 161. By rotating the hand piece 161, the threaded rod 16 is driven to rotate, so that the cross fixing plate 25 moves up and down, driving the two pillars 2 to move up and down.

[0057] A hand push piece 90 is fixedly connected to the end of the horizontal plate 8, and a wheel 91 is fixedly connected to the circumference of the lower surface of the horizontal plate 8. The staff pushes the hand push piece 90 to move the entire device.
