[0035] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0036] Reference Figure 1-Figure 3 The present invention provides an embodiment of a road surface grinding device for highway engineering, comprising:

[0037] Cart 1, a grinding assembly is provided inside the cart 1, and the grinding assembly is used to grind the road surface;

[0038] The support frame 2 is fixedly connected to the bottom of the cart 1. The support frame 2 is fixedly connected to the support base 3 inside. The outer wall of the support base 3 is rotatably connected to the driven wheel 4. The top of the support frame 2 is fixedly connected to the motor 5. The output end of the motor 5 is fixedly connected to the driving wheel 6. A synchronous belt 7 is provided between the driving wheel 6 and the driven wheel 4. The synchronous belt 7 is used to transmit power;

[0039] The connecting column 8 is fixedly connected to the bottom end of the driven wheel 4, and the connecting column 8 is rotatably connected to the inside of the support frame 2. The connecting column 8 is slidably connected to the sliding column 9, and the outer wall of the sliding column 9 is fixedly connected to the connecting rod 12, which is used for connection;

[0040] Cylinder 10, cylinder 10 is fixedly connected to the top of the support seat 3, the output end of cylinder 10 is fixedly connected to the push rod 11, the push rod 11 is slidably connected to the inside of the support seat 3, the connecting rod 12 is fixedly connected to the outer wall of the push rod 11, and a sweeper 13 is provided at the bottom end of the push rod 11 and the sliding column 9. The grinding assembly includes a rotating column 14 and a rotating column 2 15. The rotating column 14 is rotatably connected to the inside of the cart 1, and the rotating column 2 15 is rotatably connected to the inside of the cart 1. A grinding belt 16 is provided between the rotating column 14 and the rotating column 2 15.

[0041] Specifically, when using the grinding equipment to clean road debris, first, the output end of the cylinder 10 pushes the push rod 11 to slide inside the support base 3. After the push rod 11 is subjected to force, it drives the connecting rod 12 connected to its outer wall to move. The connecting rod 12 is subjected to force and pushes the sliding post 9 at one end to slide inside the connecting post 8. In turn, the push rod 11 and the sliding post 9 drive the bottom end of the sweeper 13 to move up and down, pressing the sweeper 13 to the ground for effective dust collection. At the same time, the output end of the motor 5 drives the driving wheel 6 to rotate. The driving wheel 6 drives the driven wheel 4 to rotate synchronously through the synchronous belt 7 on the outer wall. After the driven wheel 4 is subjected to force, it drives the connecting post 8 connected to its bottom end to rotate. The rotation of the connecting post 8 further drives the internal sliding post 9 to rotate. This mechanical transmission system enables the sliding post 9 and the push rod 11 to jointly drive the sweeper 13 to rotate. The brush on the outside of the sweeper 13 effectively removes dust and debris from the road surface through rotation, thereby achieving efficient cleaning of road debris and ensuring the cleanliness and construction quality of the road surface after the grinding operation.

[0042] Reference Figure 1 、 Figure 2 and Figure 4 The outer wall of the cart 1 is fixedly connected to a support rod 17, one end of the support rod 17 is fixedly connected to a hollow column 18, a rack 19 is fixedly connected inside the hollow column 18, a telescopic column 20 is slidably connected inside the hollow column 18, one end of the telescopic column 20 is fixedly connected to a connecting frame 21, a gear 22 is rotatably connected inside the connecting frame 21, the gear 22 is meshed with the rack 19, a handlebar 23 is slidably connected inside the telescopic column 20, one end of the handlebar 23 is fixedly connected to a rack 24, and the rack 24 is meshed with the gear 22.

[0043] Specifically, when the length and position of the handlebar 23 need to be adjusted, the handlebar 23 is first pulled, which causes the second rack 24 to move. Under the force, the second rack 24 pushes the gear 22 meshing with it to rotate inside the connecting frame 21. The rotation of the gear 22 causes it to move along the rack 19 inside the hollow column 18, thereby achieving telescopic adjustment of the handlebar 23 and the telescopic column 20.

[0044] Reference Figure 1 、 Figure 2 and Figure 4 The outer wall of the telescopic column 20 is rotatably connected to a positioning pin 25, and the positioning pin 25 is slidably connected to the inside of the handlebar 23.

[0045] Specifically, when the handlebar 23 and the telescopic column 20 are adjusted to the required length, the positioning pin 25 on the outer wall of the telescopic column 20 is rotated to the outer wall of the handlebar 23, so that one end of the positioning pin 25 is inserted into the inside of the handlebar 23 for locking. This process ensures that the handlebar 23 can be accurately adjusted according to actual needs through the engagement of the rack and the gear 22 and the fixation of the positioning pin 25, thereby meeting the usage requirements.

[0046] Working principle: When the road debris needs to be cleaned during the use of the grinding equipment, the output end of the cylinder 10 is first used to drive the push rod 11 to slide inside the support seat 3. The push rod 11 is forced to drive the connecting rod 12 connected to the outer wall to move. The connecting rod 12 is forced to drive the sliding column 9 connected at one end to slide inside the connecting column 8, so that the push rod 11 and the sliding column 9 drive the bottom end of the sweeper 13 to move up and down, and then the sweeper 13 falls to the ground, and the dust is sucked by the sweeper 13. At the same time, the output end of the motor 5 can also drive the driving wheel 6 to rotate, and the driving wheel 6 drives the driven wheel 4 to rotate synchronously through the synchronous belt 7 on the outer wall. The driven wheel 4 is forced to drive the connecting column 8 connected to the bottom end to rotate, and the connecting column 8 is forced to drive the internal sliding column 9 to rotate, so that the sliding column 9 and The push rod 11 drives the sweeper 13 to rotate, and the dust is swept by the brush outside the sweeper 13, thereby achieving the effect of effectively cleaning the debris on the road surface. When the length position of the handlebar 23 needs to be adjusted, the handlebar 23 is first pulled to drive the rack 24 to move. The rack 24 is driven by the force to drive the gear 22 meshing with it to rotate inside the connecting frame 21. During the rotation, the gear 22 will move along the rack 19 inside the hollow column 18, thereby causing the handlebar 23 and the telescopic column 20 to extend and retract. When adjusted to the appropriate position, the locating pin 25 on the outer wall of the telescopic column 20 is rotated to the outer wall of the handlebar 23, so that one end of the locating pin 25 is inserted into the handlebar 23 and locked, thereby achieving the effect of adjusting the length position of the handlebar 23 according to needs.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
