[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1
[0017] Reference Figure 1-2 As shown, an unmanned multi-functional road cleaning and recovery vehicle includes a vehicle body, a cleaning component at the front of the vehicle body cavity, and a push-pull component at the rear of the vehicle body cavity.
[0018] The cleaning assembly includes a receiving roller lifting mechanism 1, a receiving roller 2, a pushing receiving lift 3, a pushing frame 4, a receiving shovel 11, a bucket elevator 8, and a receiving box 6 fixed in the inner cavity of the vehicle body. The front end of the pushing frame 4 is provided with a push plate 5, and the rear end is hinged to the bottom of the vehicle body. The pushing receiving lift 3 is located in front of the receiving box 6, and its main body is hinged to the vehicle body. Its output end is hinged to the middle of the pushing frame 4. A horizontal fixed bracket 7 is fixed to the front of the receiving box 6. The bucket elevator 8 is set at an angle, with its upper end above the receiving box 6. A ring-shaped protective bracket 9 is provided at its rear end and fitted on the fixed bracket 7. Both sides of its lower end are provided with bearing wheels 10. The rear end of the receiving shovel 11 is hinged to the lower end of the bucket elevator 8. Both sides and the middle part of the shovel are provided with ground-contact wheels 12. Its side is connected to the bucket elevator 8 and the pushing frame 4 respectively through a first buffer 13 and a second buffer 14.
[0019] The receiving roller 2 is installed in the vehicle body through the receiving roller lifting mechanism 1. When both the receiving roller 2 and the receiving shovel 11 are lowered, the receiving roller 2 is located in front of the receiving shovel 11.
[0020] More specifically, the bucket elevator 8 is suspended from the vehicle body by two third buffers 15 on both sides of the upper end. The first buffer 13, the second buffer 14 and the third buffer 15 are all elastic buffers; an emergency brake protector 16 is installed on the second buffer 14.
[0021] In addition, the vehicle is equipped with two hydraulically adjustable support legs 22 on each side, and four forward and backward running wheels 23 and four left and right auxiliary wheels 24 at its bottom; the auxiliary wheels 24 are adjustable. The vehicle is equipped with a liftable electronic screen 26, a camera 25, and rotating lights 27, and detectors 28 on both its front and rear sides. When the road traffic control center issues a remote control command, the tow truck quickly reaches the designated road section and location under the remote control of the staff, and measures the size of the obstacles using the camera 25 and detectors 28.
[0022] When dealing with spilled items such as gravel, garbage, wood blocks, wire mesh, tarpaulin, and damaged tires on the road surface, the cleaning component at the main working end of this device can be used for rapid obstacle removal. Specifically: the material collection roller lifting mechanism 1 drives the material collection roller 2 to descend and contact the road surface; the push-to-lift mechanism 3 is activated, driving the push-to-lift frame 4 to rotate downwards, so that the ground-contact wheel 12 and the load-bearing wheel 10 are in contact with the ground; then, the obstacle removal vehicle is manually remotely controlled to move forward, the material collection roller 2 and the bucket elevator 8 are activated, the material collection roller 2 rotates and sweeps the spilled items onto the bucket elevator 8 through the material collection shovel 11, and the bucket elevator 8 then transports them into the collection box 6; specifically, the cleaning component is also equipped with a spray system for spraying and dust suppression on the material collection roller 2 and the bucket elevator 8. During the forward movement, the first buffer 13 and the second buffer 14 can provide cushioning for the material collection shovel 11.
[0023] A rubber pad is installed at the front end of the receiving shovel 11 to ensure its close contact with the ground during operation. The rubber pad's elasticity also allows the receiving shovel 11 to overcome smaller, low-lying fixed obstacles, thus promoting the continuity and stability of the clearing operation. When the receiving shovel 11 hits a fixed obstacle, it rotates counterclockwise, causing the bucket elevator 8 to shift obliquely upwards with the cooperation of the annular protective bracket 9 and the fixed bracket 7, pressing against the third buffer 15. When the second buffer 14 is stretched beyond a certain limit or pressure, the emergency brake protector 16 can send an emergency stop signal, causing the clearing vehicle to stop urgently, thereby protecting the first buffer 13, the second buffer 14, and the third buffer 15 and other auxiliary components from damage.
[0024] The push plate 5 at the front end of the pusher 4 can push larger spilled items and flatten spilled bulk items. This design, which works in conjunction with the collection shovel 11, can quickly clear and remove spilled items from the road, ensuring smooth and safe traffic. Example 2
[0025] As a preferred embodiment of the present invention, this embodiment designs the push-pull component based on Embodiment 1, specifically as follows: The push-towing assembly includes a push-towing frame 21, a lifting mechanism 17 and a vertical moving bracket 18 installed in the vehicle body. A lifting frame 19 is vertically slidably mounted on the vertical moving bracket 18. The top of the lifting frame 19 is connected to the output end of the lifting mechanism 17. A front-to-back telescopic device 20 is fixed on both its left and right sides. The output ends of the telescopic devices 20 are all set to the rear and are fixedly connected to the push-towing frame 21.
[0026] The push-and-collect lift 3, the lifting frame lifting mechanism 17, and the telescopic device 20 are all hydraulic cylinders.
[0027] The push-and-tow frame 21 can be used for both pushing and dragging operations. For excessively large or heavy items such as wooden crates, stones, and equipment on the road, the push-and-tow assembly at the auxiliary working end of the device can be used for clearing. Specifically: for items that can be moved by the power of the clearing vehicle itself, the lifting mechanism 17 and the telescopic device 20 drive the push-and-tow frame 21 to rise and extend to a suitable height and position, and then push and drag the items to the roadside. For items that are too heavy to be moved by the clearing vehicle itself, the hydraulic lifting support leg 22 is activated. After the hydraulic lifting support leg 22 is lowered to slightly lift the entire device, the telescopic device 20 is controlled to drive the push-and-tow frame 21 to push or drag the items a distance to the roadside. Then, the clearing vehicle position is changed, the hydraulic lifting support leg 22 is lowered again, and the push-and-tow frame 21 is used to push and drag the items a further distance to the roadside. This process is repeated until the items are moved to the roadside or other areas that do not obstruct traffic safety.
[0028] This clearing and recovery vehicle can be deployed in highway service areas, parking areas, and other locations. When debris is spilled on the highway, staff can remotely control the nearest clearing and recovery vehicle to arrive at the scene promptly for clearing operations. The device is also equipped with various rescue tools, enabling it to provide timely emergency services to rescue personnel in the event of a traffic accident.
[0029] In summary, this device can be remotely controlled by personnel, allowing it to move forward and backward, as well as to move left and right using the lifting auxiliary wheels 24. The cleaning component can not only quickly clear debris such as sand, garbage, wood blocks, wire mesh, canvas, and damaged tires from the road surface, but also push larger debris using the push plate 5. The push-and-tow component can perform both pushing and dragging operations, enabling it to clear excessively large or heavy items such as wooden boxes, stones, and equipment from the road surface.
[0030] This invention is not limited to the embodiments described above. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this invention, and the changed content still falls within the protection scope of this invention.
