Description

Technical Field

[0001] This utility model relates to the field of steering wheel technology, and in particular to a steering wheel mechanism for automatic laser-guided movement. Background Technology

[0002] During the operation of a milling and grinding machine, it is generally moved by remote control or manual pushing. The force applied by remote control and manual pushing cannot be completely uniform. With slight deviation, the machine may lean to one side. In addition, the concrete ground during construction is often uneven. When the wheels encounter ups and downs, the path will naturally be affected. Furthermore, if there are debris or slippery surfaces, changes in friction will also cause the machine to deviate.

[0003] Offset causes the grinder to move back and forth in a curved path, resulting in an irregular coverage area, with many overlapping or missed areas, low efficiency, and irregular movement path is one of the main causes of "wavy" patterns on the ground, which seriously affects aesthetics and functionality; uneven grinding and substandard ground flatness require rework, which is not only time-consuming but also increases costs. Utility Model Content

[0004] The purpose of this invention is to provide a laser-guided steering wheel mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A laser-guided steering wheel mechanism includes a laser receiver, a grinding machine connecting frame, a mounting plate, a steering device, and a drive device. The mounting plate has a first fixed frame and a second fixed frame connected to its bottom. The laser receiver includes a protective cover, a laser receiver, and a fixed cover. The fixed cover is mounted on the first fixed frame, and the laser receiver is installed inside the fixed cover. The protective cover is connected to the top of the fixed cover. The drive device is installed between the first and second fixed frames. The steering device is fixed to the mounting plate. The grinding machine connecting frame is connected to the steering device on the top of the mounting plate. The laser receiver contains a controller, which is electrically connected to the steering device.

[0007] Preferably, the steering device includes a slewing bearing, a steering motor, a reducer, and a steering gear. The slewing bearing includes an inner ring and an outer ring, which are rotatable relative to each other. The inner ring is fixed to the top of the mounting plate. A through hole is provided on the outer circumference of the mounting plate. The steering motor is connected to the reducer. The steering gear is mounted on the output shaft of the reducer. The steering motor and the reducer are fixed to the bottom of the mounting plate. The steering gear passes through the through hole and is located at the top of the mounting plate. The outer ring has gear teeth, and the steering gear meshes with the outer ring at the top of the mounting plate.

[0008] Preferably, a connecting plate is fixed at the bottom of the grinding machine connecting frame, and the connecting plate is connected to the outer ring of the slewing bearing.

[0009] Preferably, both the first fixing bracket and the second fixing bracket are provided with round holes. The second fixing bracket is installed on both sides of the bottom of the mounting plate, and the first fixing bracket is installed between the two second fixing brackets on the same side.

[0010] Preferably, the drive device includes a drive motor, a second reducer, a differential, and a drive wheel. The drive motor is mounted on the outside of the first fixed frame and located inside the fixed cover. The second reducer is mounted on the first fixed frame. The differential is mounted between the two second fixed frames. The drive motor is connected to the second reducer through a round hole on the first fixed frame. The second reducer is connected to the differential drive shaft. The drive wheel is connected to the differential output shaft through round holes on the two second fixed frames.

[0011] Preferably, the controller is a PCB circuit board electrically connected to the steering motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses an external laser emitter and a laser receiver mounted on the steering wheel to ensure that the steering wheel always follows the laser movement. When the laser received by the laser receiver deviates from its position on either side of the laser receiver, the controller adjusts the direction of the steering wheel's movement by controlling the steering motor, thereby keeping the grinding machine mounted on the steering wheel in a straight line. The straight path planning saves more time and effort and ensures grinding quality and flatness.

[0014] Straight-line walking ensures consistent overlapping of grinding paths, avoiding areas of insufficient or excessive grinding; it improves the overall flatness of the ground, avoids "wavy" patterns, and offers high coverage efficiency with clear path planning, avoiding the need for back-and-forth corrections or re-grinding due to deviations, greatly saving time and effort; it also makes it easy to plan systematic grinding paths that cover the entire area, reducing unnecessary movement.

The bottom of the mounting plate 5 is connected to a first fixing frame 52 and a second fixing frame 53. The laser receiver 2 includes a protective cover 21, a laser receiver 22, and a fixing cover 23. The fixing cover 23 is mounted on the first fixing frame 52, and the laser receiver 22 is installed inside the fixing cover 23. The protective cover 21 is connected to the top of the fixing cover 23. The drive device is installed between the first fixing frame 52 and the second fixing frame 53. The steering device is fixed to the mounting plate 5. The grinding machine connecting frame 3 is connected to the steering device at the top of the mounting plate 5. The laser receiver 22 contains a controller, which is electrically connected to a steering motor 6. The controller is a PCB circuit board.

[0022] The steering device includes a slewing bearing 4, a steering motor 6, a reducer 61, and a steering gear 62. The slewing bearing 4 includes an inner ring 41 and an outer ring 42, which can rotate relative to each other. The inner ring 41 is fixed to the top of the mounting plate 5. A through hole 51 is provided on the outer circle of the mounting plate 5. The steering motor 6 is connected to the reducer 61. The steering gear 62 is mounted on the output shaft of the reducer 61. The steering motor 6 and the reducer 61 are fixed to the bottom of the mounting plate 5. The steering gear 62 passes through the through hole 51 and is located at the top of the mounting plate 5. The outer ring 42 has gear teeth, and the steering gear 62 meshes with the outer ring 42 at the top of the mounting plate 5.

[0023] A connecting plate 31 is fixed at the bottom of the grinding machine connecting frame 3, and the connecting plate 31 is connected to the outer ring 42 of the slewing bearing 4.

[0024] Both the first fixing bracket 52 and the second fixing bracket 53 have round holes. The second fixing bracket 53 is installed on both sides of the bottom of the mounting plate 5, and the first fixing bracket 52 is installed between the two second fixing brackets 53 on the same side.

[0025] The drive unit includes a drive motor 7, a second reducer 71, a differential 72, and a drive wheel 8. The drive motor 7 is mounted on the outside of the first fixed frame 52 and inside the fixed cover 23. The second reducer 71 is mounted on the first fixed frame 52. The differential 72 is mounted between the two second fixed frames 53. The drive motor 7 is connected to the second reducer 71 through the round hole on the first fixed frame 52. The second reducer 71 is connected to the drive shaft of the differential 72. The drive wheel 8 is connected to the output shaft of the differential 72 through the round hole on the two second fixed frames 53.

[0026] The working principle of this utility model:

[0027] First, the grinder is installed on the grinder connecting frame 3 and connected to the steering wheel mechanism. Then, the laser emitter 1 is placed on one side of the ground to be ground. Then, the laser receiver 22 located on the other side of the steering wheel mechanism is aligned with the laser emitter 1 so that it receives the laser signal. The drive motor 7 is started, and the drive wheel 8 is driven to move through the reducer 71 and the differential 72. When the grinder deviates and the laser hits both sides of the laser receiver 22, the controller controls the steering motor 6 to operate, and drives the steering gear 62 to rotate through the reducer 61.

[0028] The inner ring 41 of the slewing bearing 4 is fixedly connected to the mounting plate 5. The inner ring 41 and the mounting plate 5 can rotate relative to the outer ring 42. The outer ring 42 is fixed on the grinding machine connecting frame 3. The steering motor 6 drives the steering gear 62 to rotate. Since the steering gear 62 meshes with the gear teeth of the outer ring 42, and the steering motor 6 and the reducer 61 are fixed on the mounting plate 5, the steering gear 62 will revolve around the outer ring 42 and drive the mounting plate 5 and the inner ring 41 to rotate, thereby realizing the steering of the drive wheel 8. The differential 72 enables the left and right drive wheels 8 to rotate at different speeds. When the drive wheels 8 are turning or driving on uneven roads, the left and right drive wheels 8 roll at different speeds to ensure that the drive wheels 8 on both sides make pure rolling motion. When the laser receiver 22 senses that the laser is in the middle position, the controller controls the drive wheel 8 to return to the center and keep the grinding machine traveling in a straight line.
