Description

Technical Field

[0001] This utility model relates to the field of road marking removal technology, and in particular to a road marking removal vehicle for road maintenance. Background Technology

[0002] In road maintenance operations, road marking removal vehicles are key equipment for ensuring the efficient replacement of old markings and the dynamic adjustment of road functions. Their performance is directly related to the recognizability of new markings, the road traffic safety factor, and the integrity of the road surface structure. With the continuous expansion of the current traffic network and the continuous increase in traffic volume on urban roads and highways, road markings need to be frequently updated according to the needs of traffic organization optimization and road upgrading and reconstruction. Especially at intersections, tunnel entrances and exits, toll stations, and other complex road sections, not only is it required that the removal operation be completed quickly to reduce traffic congestion, but also that strict standards be imposed on the removal accuracy and road surface protection.

[0003] The current mainstream mechanical grinding type road marking removal vehicles generally suffer from the core deficiency of lacking grinding disc adjustment function. The grinding angle, pressure and working trajectory of their grinding discs are mostly fixed settings, which cannot be dynamically adapted to the actual shape of the road markings. At present, the industry mainly relies on manual operation of the cleaning vehicle to move the grinding disc to adjust its working position so that the grinding disc gradually fits the edge of the road marking. However, this manual movement solution has its shortcomings. The accuracy of manual adjustment depends on the operator's experience. It is easy for visual errors or operation delays to cause the grinding disc to deviate from the road marking, resulting in mis-grinding of the road surface or road marking residue, which requires subsequent manual secondary cleaning. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a road marking removal vehicle for road maintenance, which aims to improve the problem that the grinding angle, pressure and working trajectory of the grinding disc in the prior art are mostly fixed and cannot be dynamically adapted to the actual shape of the marking.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a road marking removal vehicle for road maintenance, comprising a motor slot and a vehicle body. A motor is fixedly connected to the inner wall of the motor slot. A rotating shaft is fixedly connected to the output end of the motor.

A bearing is rotatably connected to the rear side of the sleeve rod. A fixing block is fixedly connected to the rear side of the bearing. A lifting mechanism is provided on the right side of the motor slot, which is used to lift the vehicle when not in use.

[0006] As a further description of the above technical solution:

[0009] The left side of the connecting block three is fixedly connected to the rear side of the motor slot, and the top of the connecting block two is fixedly connected to the bottom of the motor slot.

[0010] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the screw rod is driven to rotate by a motor-driven transmission assembly, so that the sleeve rod carries the grinding plate and moves with the long plate. The position of the grinding plate can be flexibly adjusted according to the road markings of different widths. The removal of markings of various specifications can be completed without changing the equipment, which greatly improves the versatility and work efficiency of the equipment and reduces the equipment investment cost when operating in multiple scenarios.

[0022] 2. In this utility model, when the equipment is not in use, the cylinder drives the connecting rod and the connecting plate assembly to lift the motor slot, thereby lifting the grinding plate off the ground. This avoids unnecessary wear caused by long-term friction between the grinding plate and the ground, reduces the frequency of grinding plate replacement, lowers equipment maintenance costs, and also prevents the grinding plate from being damaged by debris on the ground when idle, ensuring the accuracy of subsequent operations.

[0039] Working principle: When it is necessary to clear road markings of different widths, the motor 3 is started, which drives the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 causes the bevel gear 5 to rotate, and the rotation of the bevel gear 6 to follow the rotation of the bevel gear 5. At this time, the rotating shaft 7 and the threaded rod 8 will rotate with the bevel gear 6, which in turn allows the sleeve rod 9 to rotate on the outer wall of the threaded rod 8. This allows the sleeve rod 9 to move the bearing 12, the fixing block 13, and the long plate 14, which in turn allows the outer shell 17 and the grinding plate 18 to move, thereby adjusting the road markings according to different widths.

[0040] When not in use, by activating cylinder 202, the output end of cylinder 202 drives the connecting rod 203 to move, causing the connecting block 204 to move with the connecting rod 203, which in turn drives the connecting plate 205 to rotate. The rotation of the connecting plate 205 causes the rotating shaft 206 to rotate, which in turn causes the connecting plate 207 to rotate, thereby driving the rotating shaft 208 to rotate. This lifts the motor slot 1 upwards, ultimately achieving the goal of lifting the grinding plate 18 when not in use, thus preventing the grinding plate 18 from constantly rubbing against the ground.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
