Description

Technical Field

[0001] This invention relates to a road construction equipment, specifically a transmission mechanism for a road marking machine. Background Technology

[0002] A road marking machine is a specialized device used to mark various traffic lines on roads, urban roads, parking lots, and squares. The transmission mechanism, as a core functional module, is responsible for transmitting power from the engine to the wheels for movement and also distributing some power to the marking actuators and other loads. Its transmission efficiency, speed control accuracy, and structural compactness directly determine the overall marking quality, operating efficiency, and maintenance costs. While existing technologies employ hydraulic steering systems or multi-motor independent drives to improve maneuverability, these solutions are complex, costly, and have a high failure rate, hindering large-scale adoption. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a road marking machine transmission mechanism that is simple in structure, cost-controllable, and has good transmission effect.

[0004] To solve the above-mentioned technical problems, the transmission mechanism of the road marking machine of the present invention includes a base plate, on which a drive transmission sprocket and a transmission shaft for establishing a transmission relationship with a drive mechanism are rotatably mounted. A transmission sprocket for establishing a transmission relationship with the drive transmission sprocket is fixed on the transmission shaft. A travel transmission sprocket and a transmission gear for establishing a transmission relationship with a travel mechanism are also fixed on the transmission shaft. A movable plate is also oscillatingly mounted on the base plate, on which a marking transmission gear for establishing a transmission relationship with a marking mechanism is rotatably mounted. The marking transmission gear can selectively establish a transmission relationship with the transmission gear by oscillating.

[0005] A support plate is fixed on the base plate, and a movable groove is opened on the support plate. A drive transmission sprocket shaft is adjustablely arranged in the movable groove, and the drive transmission sprocket is rotatably mounted on the drive transmission sprocket shaft.

[0006] A scribing transfer shaft is rotatably mounted on the base plate. A transfer rod is fixed to one end of the scribing transfer shaft, and the movable plate is installed at an adjustable angle at the other end of the scribing transfer shaft.

[0007] A support is fixed on the base plate, and a transition gear set is rotatably mounted on the support. The scribing transmission gear and the transmission gear are connected by the transition gear set.

[0008] The number of gears in the transition gear set is odd.

[0009] An encoder with an input shaft is mounted on the base plate, an encoder gear is fixed on the input shaft, and a speed measuring gear meshing with it is fixed on the transmission shaft.

[0010] The advantages of this invention are: (1) The driving force from the drive mechanism is first transmitted to the drive shaft through the chain drive mechanism, and then transmitted to the walking mechanism and the marking mechanism through the sprockets and gears on the drive shaft. The overall structure is simple and compact, and there is no need for a hydraulic system or multi-motor drive. The failure rate is low, so the maintenance cycle can be effectively extended, thereby improving the working efficiency and service life of the marking machine. (2) A speed measuring gear is also fixed at the end of the transmission shaft. The speed measuring gear meshes with the encoder gear on the encoder input shaft, so that the speed of the transmission shaft can be detected by the encoder, which facilitates speed control and has high speed control accuracy, thus improving the scribing quality. (3) A scribing transmission shaft is rotatably installed under the base plate. One end of the scribing transmission shaft is fixed with a transmission rod for the operator to operate, and the other end is equipped with a movable plate with adjustable angle. A scribing transmission gear that forms a transmission relationship with the scribing mechanism is rotatably installed through the movable plate. The scribing transmission gear can mesh or disengage with the transition gear set as the transmission rod swings, thereby selectively transmitting the driving force from the transmission shaft to the scribing mechanism, so that it can perform or stop scribing operations at any time. Under the premise of meeting the usage requirements well, the structure is simple and ingenious and has good operability. Attached Figure Description

[0012] The transmission mechanism of the road marking machine of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] As shown in the figure, the transmission mechanism of the road marking machine of the present invention includes a base plate 1 of the marking machine, a support plate 8 fixed below the base plate 1, a movable groove 9 on the support plate 8, and a drive transmission sprocket shaft 10 adjustablely positioned within the movable groove 9. The drive transmission sprocket shaft 10 can be fixed after being moved to the desired position, and a drive transmission sprocket 2 is rotatably mounted on it. The drive transmission sprocket 2 and the driving mechanism of the marking machine (not shown in the figure) are connected by a transmission relationship. A transmission shaft 4 is rotatably mounted above the base plate 1 via two bearing seats. A transmission sprocket 5 is fixed on the transmission shaft 4 at a position corresponding to the drive transmission sprocket 2. A through groove is provided on the base plate 1 for the lower part of the transmission sprocket 5 to pass through. The transmission sprocket 5 and the drive transmission sprocket 2 are connected by a chain (not shown in the figure) to form a chain transmission relationship, so that the driving force generated by the driving mechanism can be transmitted to the transmission sprocket 5 through the drive transmission sprocket 2, thereby driving the transmission shaft 4 to rotate.

[0014] One end of the drive shaft 4 is fixed with a travel transmission sprocket 6, which forms a transmission relationship with the line marking machine's traveling mechanism (not shown in the figure), enabling the rotation of the drive shaft 4 to drive the traveling mechanism and realize the traveling function of the line marking machine. The other end of the drive shaft 4 is fixed with a speed measuring gear 19. Above the base plate 1, next to the speed measuring gear 19, an encoder 17 with an input shaft 16 is fixedly installed. An encoder gear 18 that meshes with the speed measuring gear 19 is fixed on the input shaft 16, so that the rotational speed of the drive shaft 4 can be detected for speed control.

[0015] A transmission gear 7 is fixed on the transmission shaft 4 between the transmission sprocket 5 and the encoder gear 18. A support 14 is fixed on the top of the base plate 1 next to the transmission gear 7. A transition gear set 15 is rotatably mounted on the support 14. The number of gears in the transition gear set 15 needs to be odd to meet the transmission direction control requirements. In this embodiment, the transition gear set 15 consists of three meshing gears, one of which is an edge gear that meshes with the transmission gear 7. A scribing transmission shaft 11 is rotatably mounted on a bracket below the base plate 1. One end of the scribing transmission shaft 11 is fixed with a transmission rod 12, and the other end is equipped with a movable plate 13 at an adjustable angle. That is, the movable plate 13 can be fixedly connected to the scribing transmission shaft 11 after adjusting the relative angle between it and the transmission rod 12. A scribing transmission gear 3 is rotatably mounted on the movable plate 13. The scribing transmission gear 3 and the scribing mechanism of the scribing machine (not shown in the figure) form a transmission relationship, so that when the operator pulls the transmission rod 12, the scribing transmission shaft 11 can transmit torque to the movable plate 13, causing the scribing transmission gear 3 on it to swing accordingly, and then engage or disengage with another edge gear in the transition gear set 15, thereby selectively transmitting the driving force from the transmission shaft 4 to the scribing mechanism, so that it can start or stop the scribing operation at any time as needed.

[0016] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
