Description

Technical Field

[0001] This utility model relates to the technical field of road cutting machine accessories, specifically an automatic road cutting machine two-wheel synchronous guide adaptive device for potholes. Background Technology

[0002] Automatic road cutting machines are core equipment in municipal road maintenance and new road surface joint cutting construction. Their cutting accuracy directly determines the sealing performance of road expansion joints and the service life of the road. Currently, the guiding systems of mainstream automatic road cutting machines mostly adopt fixed wheel sets or simple mechanical linkage structures, but there are still technical pain points in actual operation scenarios, which seriously restrict the construction quality and efficiency.

[0003] When encountering minor bumps, gravel obstacles, or uneven wear of the wheel set during the cutting process, it is easy for the wheel speed to deviate on one side, causing the guide wheel trajectory to deviate from the preset cutting line. This will eventually result in problems such as "deviation" or "wavy" road cuts, requiring additional manpower for recutting or repair, which increases construction costs.

[0004] Poor adaptability to uneven road surfaces leads to equipment damage and safety hazards: Municipal construction roads (such as old road renovation sites, uneven roads after rain) commonly have potholes, depressions, or settlement areas. Traditional guide devices often have a fixed wheel height design, which cannot adjust the wheel posture and ground pressure in real time according to road undulations. On the one hand, when the wheel rolls over the edge of a pothole, it is prone to violent bumps, causing a sudden increase in pressure between the cutting blade and the road surface, which may cause the blade to break or the main shaft to deform. On the other hand, when the wheel gets stuck in a depression, it may "get stuck," causing the equipment to stop suddenly or tilt up on one side, which not only interrupts construction but may also pose a safety risk to the operator. Utility Model Content

[0005] The purpose of this invention is to provide an automatic road cutter with a two-wheel synchronous steering adaptive device for potholes, in order to solve the problems of difficulty in synchronizing the two steering wheels and poor adaptability to potholes in the existing technology mentioned in the background, which leads to equipment damage and safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic road cutter with two-wheel synchronous guidance and adaptive device for potholes, comprising a mounting plate, a sleeve provided at the middle of one top end of the mounting plate, a motor mounted at the middle of the top of the mounting plate, the output end of the motor penetrating the interior of the mounting plate and fitted with a drive sprocket, mounting posts provided on both sides of the bottom of the mounting plate, steering sprockets fitted on the outer sides of each mounting post, guide wheels provided at the bottom of each mounting post, and a chain fitted on the outer sides of both sets of steering sprockets;

[0007] One end of the bottom of the mounting plate is rotatably connected to a rotating plate via a rotating shaft. A tension sprocket is rotatably connected to the rotating plate via a fixed shaft. A tension spring is sleeved on the shaft of the tension sprocket. A threaded rod is installed at the bottom of the mounting plate away from the tension sprocket, and the other end of the tension spring is disposed on the threaded rod.

[0008] Preferably, a bearing is provided inside the sleeve.

[0009] Preferably, a locking nut is provided on the outer side of the threaded rod mounted on the mounting plate.

[0010] Preferably, the drive sprocket and the tension sprocket are located at both ends of the chain.

[0011] Preferably, a bearing is provided at the connection between the mounting column and the mounting plate.

[0012] Preferably, the outer side of the guide wheel is provided with anti-slip texture.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The automatic road cutter's two-wheel synchronous guiding pothole road adaptive device is connected to the external shaft end through a sleeve. During the movement, if it encounters a pothole road, it can swing left and right like a seesaw to adapt to complex environments and achieve the effect of adapting to pothole roads; the chain transmission drives the two sets of guide wheels to turn synchronously; and through the cooperation of the rotating plate, tension sprocket and tension spring, the elastic potential energy of the tension spring drives the tension sprocket to adjust the tension of the chain, so as to ensure the stability of the chain drive structure and thus maintain the stability of the synchronous turning of the two wheels.

[0023] It should be noted that...

[0024] To address the aforementioned issues, this solution provides an adaptive device for two-wheel synchronous guidance of pothole-prone surfaces in an automatic road cutting machine. In municipal road maintenance and new road surface cutting, the automatic road cutting machine is a core piece of equipment, its cutting accuracy directly determining the sealing performance of road expansion joints and the service life of the road. Currently, most mainstream automatic road cutting machines use fixed wheel sets or simple mechanical linkage structures for their guidance systems, but these still present technical challenges in actual operation, severely restricting construction quality and efficiency. When encountering minor road surface bumps, gravel obstacles, or uneven wheel wear during cutting, unilateral wheel speed lag or deviation is easily observed, causing the guide wheel trajectory to deviate from the preset cutting line, ultimately resulting in problems such as "deviation" or "wavy" road surface cuts. This necessitates additional manpower for recutting or repair, increasing construction costs. Poor adaptability to pothole-prone surfaces leads to equipment damage and safety hazards: Municipal construction roads (such as old road renovation sites or uneven surfaces after rain) commonly have potholes, depressions, or settlement areas. Traditional guide devices often have a fixed wheel height, which cannot adjust the wheel posture and ground pressure in real time according to road undulations. On the one hand, when the wheel rolls over the edge of a pothole, it is prone to violent bumps, which causes a sudden increase in pressure between the cutting blade and the road surface, leading to blade breakage or spindle deformation. On the other hand, when the wheel gets stuck in a recessed area, it may "get stuck", causing the equipment to stop suddenly or tilt up on one side, which not only interrupts the construction but may also cause safety risks to the operators.

[0025] For details, please refer to Figures 1-3 , Figure 1 This is the front view of the present invention; Figure 2 For the present utility model Figure 1 A bottom view of point AA; Figure 3 This is a top view of the present invention.

[0026] This application provides an automatic road cutting machine with a two-wheel synchronous guide for potholes and road surfaces, including a mounting plate 1. A sleeve 2 is provided in the middle of the top end of the mounting plate 1. A motor 3 is installed in the middle of the top end of the mounting plate 1. The output end of the motor 3 passes through the interior of the mounting plate 1 and is fitted with a drive sprocket 4. Mounting posts 5 are provided on both sides of the bottom of the mounting plate 1. Steering sprockets 6 are fitted on the outer side of each mounting post 5. A guide wheel 7 is provided at the bottom of the mounting post 5. A chain 8 is fitted on the outer side of both sets of steering sprockets 6.

[0027] One end of the bottom of the mounting plate 1 is rotatably connected to a rotating plate 9 via a rotating shaft. A tension sprocket 10 is rotatably connected to a fixed shaft on the rotating plate 9. A tension spring 11 is sleeved on the shaft of the tension sprocket 10. A threaded rod is installed at the bottom of the mounting plate 1 away from the tension sprocket 10, and the other end of the tension spring 11 is set on the threaded rod.

[0028] In this embodiment, a bearing is provided inside the sleeve 2.

[0029] It should be noted that the main bearing, which is connected to the shaft of the external walking mechanism, is the key part of the swing of the mounting plate 1. When encountering potholes, it can swing left and right, improving the self-adaptive effect of the device.

[0030] In this embodiment, a locking nut is provided on the outer side of the threaded rod installed on the mounting plate 1.

[0031] It should be noted that the position of the tension spring 11 is locked by tightening the lock nut.

[0032] In this embodiment, the drive sprocket 4 and the tension sprocket 10 are located at both ends of the chain 8.

[0033] It should be noted that, as Figure 2 As shown, the drive sprocket 4 and the tension sprocket 10 are located in the middle section of the chain 8. The drive sprocket 4 is driven by the motor 3, which drives the two sets of steering sprockets 6 to turn through the chain 8. The tension sprocket 10 is adapted to the chain 8 to adjust the tension of the chain 8.

[0034] In this embodiment, a bearing is provided at the connection between the mounting column 5 and the mounting plate 1.

[0035] It should be noted that the mounting column 5 rotates with the steering sprocket 6.

[0036] In this embodiment, the outer side of the guide wheel 7 is provided with anti-slip texture.

[0037] It should be noted that the purpose of adding anti-slip treads to the outer side of the guide wheel is to increase the friction between the wheel and the ground, so as to prevent the wheel from slipping due to lateral forces when turning, thereby accurately controlling the steering trajectory.

[0038] It can play a role in two key scenarios: first, when the cutting equipment turns, it prevents the wheels from "side slipping" due to inertia and deviating from the preset route; second, on wet, gravelly, and potholed roads, it can embed itself into the ground through the texture or remove accumulated water to maintain grip when turning and avoid the equipment from going out of control.

[0039] Firstly, the sleeve 2 is connected to the external shaft end. During the journey, if it encounters a bumpy road surface, it can swing left and right like a seesaw, so that this utility model can adapt to complex environments and achieve an adaptive effect.

[0040] The motor 3 drives the drive sprocket 4 to rotate, the drive sprocket 4 drives the chain 8 to rotate, the chain 8 synchronously drives the two sets of steering sprockets 6 to rotate, and the steering sprockets 6 drive the mounting column 5 and the guide wheel 7 mounted on it to perform two-wheel steering operation.

[0041] The device is equipped with a rotating plate 9, a tension sprocket 10, and a tension spring 11. The elastic potential energy of the tension spring 11 drives the tension sprocket 10 to deflect around one end of the rotating plate 9, thereby adjusting the tension of the chain 8 to ensure the stability of the transmission structure.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
