Description

Technical Field

[0001] This utility model belongs to the field of laser paving machine technology, specifically relating to a three-dimensional RTK laser paving machine. Background Technology

[0002] The 3D RTK laser paver is an intelligent paving machine integrating RTK (Real-Time Kinematic) technology and a laser elevation control system. It is primarily used for automated construction of high-precision concrete or asphalt pavements. This equipment achieves centimeter-level planar position control through RTK satellite positioning, combined with a laser elevation sensing system to ensure the smoothness of the paved surface matches the design elevation, significantly improving construction accuracy. Simultaneously, its 3D control system can adjust the paving thickness and slope in real time to adapt to complex road shapes. Compared to traditional pavers, this equipment offers advantages such as high automation, high construction efficiency, and low labor costs, and is widely used in high-standard road surface projects such as highways, airport runways, and municipal roads.

[0003] When a 3D RTK laser paver operates on hard surfaces, the small contact area between the hard surface and the tires, along with the low coefficient of friction, can easily lead to insufficient tire adhesion. This reduced adhesion can cause tire slippage, affecting not only the stability of the equipment's movement but also the efficiency and quality of the paving operation. Utility Model Content

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example

[0027] Reference Figure 1-4 This is an embodiment of the present invention, which provides a three-dimensional RTK laser paving machine, comprising:

[0028] The paving mechanism 100 includes a paver body 110, two side frames 120 fixedly installed on the surface of the paver body 110, and a movable tire 130 disposed on one side of the side frame 120 for moving the paver body 110.

[0029] The anti-slip mechanism 200 includes a gripping component 210 for preventing the mobile tire 130 from slipping on hard ground, and an adjusting component 220 for adjusting the gripping performance of the gripping component 210.

[0030] The gripping component 210 and the adjusting component 220 work together to increase the friction between the mobile tire 130 and the ground, preventing the mobile tire 130 from slipping. This solves the problem that the traditional mobile tire 130 is prone to slipping when moving on hard ground, which affects the paving efficiency. It achieves the effect of preventing the mobile tire 130 from slipping on hard ground and improving paving efficiency.

[0031] Specifically, the gripping component 210 includes several cylinders 211 disposed on the moving tire 130, connecting rods 212 elastically mounted on the cylinders 211, gripping floor 213 fixedly mounted on one side of the connecting rods 212, and several protrusions 214 fixedly mounted on the surface of the gripping floor 213 for gripping.

[0032] When the mobile tire 130 rotates, the spring 215 maintains the pushing force on the connecting rod 212, which in turn pushes the gripping floor 213 and the protrusion 214, ensuring that the protrusion 214 is always in full contact with the ground, thereby increasing the friction between the mobile tire 130 and the ground and preventing the mobile tire 130 from slipping on hard ground, which would affect the paving efficiency of the paver body 110.

[0033] Furthermore, a spring 215 is fixedly installed inside the cylinder 211, and the other end face of the spring 215 is fixedly connected to one side of the connecting rod 212.

[0034] The spring 215 is used to maintain the elasticity of the connecting rod 212, thereby enabling the connecting rod 212 to maintain the thrust on the gripping floor 213 and the protrusion 214, thus improving the gripping effect of the protrusion 214.

[0035] Preferably, a plurality of positioning sleeves 216 for limiting the connecting rod 212 are fixedly installed on the surface of the movable tire 130, and the positioning sleeves 216 are sleeved on the surface of the connecting rod 212.

[0036] The positioning sleeve 216 is used to limit the connecting rod 212, improve the stability of the connecting rod 212 during displacement, and prevent the gripping floor 213 from shifting, which would cause the protrusion 214 to not grip the ground sufficiently.

[0037] Furthermore, the adjustment component 220 includes a circular box 221 fixedly mounted on the surface of the movable tire 130, a rotating screw 222 threadedly mounted inside the circular box 221, a plurality of pressing blocks 223 fixedly mounted on the surface of the rotating screw 222, and a plurality of transmission rods 224 inserted into the surface of the circular box 221 and used in conjunction with the pressing blocks 223.

[0038] The other end of the transmission rod 224 is fixedly connected to the cylinder 211.

[0039] When the protrusion 214 is used on the ground for a long time, it will be worn and the distance between the protrusion 214 and the ground needs to be adjusted. Rotating the rotating screw 222 will drive the pressing block 223 to rotate. At the same time, the pressing block 223 will move laterally, but it will not affect the pressing of the pressing block 223 on the transmission rod 224. The transmission rod 224 will be extended when it is pressed, thereby driving the cylinder 211 to adjust the position of use and ensure the gripping performance of the protrusion 214.

[0040] Specifically, the surface of the cylinder 211 is provided with a threaded groove for use with the rotating screw 222, and the arc surface of the circular box 221 is provided with several connecting grooves for use with the transmission rod 224.

[0041] The threaded groove is used to cooperate with the rotating screw 222, which facilitates the rotation and positioning of several extrusion blocks 223 by the rotating screw 222, thereby facilitating the extension and retraction of the drive rod 224.

[0042] Furthermore, the side where the extrusion block 223 and the transmission rod 224 contact each other is curved.

[0043] When in use, as the movable tire 130 rotates, the spring 215 maintains the pushing force on the connecting rod 212, which in turn keeps pushing the gripping floor 213 and the protrusion 214, so that the protrusion 214 is always in full contact with the ground, increasing the friction between the movable tire 130 and the ground, thereby preventing the movable tire 130 from slipping on hard ground;

[0044] After prolonged use, the protrusion 214 will wear down and the distance between it and the ground needs to be adjusted. Rotating the rotating screw 222 will cause the pressing block 223 to rotate, and the pressing block 223 will move laterally. However, this does not affect the pressing of the pressing block 223 on the transmission rod 224. The transmission rod 224 will be extended when pressed, thereby driving the cylinder 211 to adjust its position and ensure the gripping performance of the protrusion 214.

[0045] In summary, the cooperation between the gripping component 210 and the adjusting component 220 is used to increase the friction between the mobile tire 130 and the ground, preventing the mobile tire 130 from slipping. This solves the problem that the traditional mobile tire 130 is prone to slipping when moving on hard ground, which affects the paving efficiency. It achieves the effect of preventing the mobile tire 130 from slipping on hard ground and improving paving efficiency.
