[0028] As Figure 1 - Figure 2 shown, a small subgrade and pavement rolling device includes a frame 1, an image acquisition mechanism integrated on the frame 1, a traveling mechanism 8 arranged on the frame 1, a rolling mechanism arranged on the frame 1, and a manual operation platform; the image acquisition mechanism includes a front camera system and a multi-directional camera system, and both the front camera system and the multi-directional camera system include industrial cameras 7; the rolling mechanism includes a rolling roller 2, a connecting shaft 3 connected between the rolling roller 2 and the frame 1, and a hydraulic lifting mechanism connected to the frame 1, and the hydraulic lifting mechanism is connected to the middle of the rolling roller 2.

[0029] Compared with the prior art, in the prior art, miniaturized road rollers mainly use an internal combustion engine driven manually to drive the entire rolling wheel or rolling roller 2 to move. Its disadvantages are also very obvious. On the one hand, when steering, a steering gear is used to push a pull rod to drive the rear wheel or front wheel fixed on the frame 1 to achieve mechanical or hydraulic steering. The problems are that the traveling speed change is not flexible, the steering is too heavy, it is difficult to achieve coordinated control of steering and traveling, and it affects the operation and compaction effect in a narrow space. On the other hand, manual operation is still required, and the operation intensity is high. In the present utility model, a hydraulic lifting mechanism is used to control the lifting of the front rolling roller 2, thereby improving the steering performance of the vehicle and the passing performance on the road surface, and being able to reach the operation area better; at the same time, the present utility model uses different camera systems arranged in multiple directions for identification, and later through image processing technology, remote operation processing can be carried out to reduce the manual operation intensity and improve the construction efficiency.

[0030] The manual operation platform includes a platform 9 connected to the bottom of the frame 1 and a handrail 10 connected to the frame 1. The present utility model can also adopt a manual operation mode, and the operator operates on the platform 9. The two operation modes make the structure more flexible.

[0031] The front camera system includes a rotating robotic arm 6, and an industrial camera 7 is connected to the end of the rotating robotic arm 6. The multi-directional camera system includes a lifting bracket 11 and a plurality of industrial cameras 7 connected to the lifting bracket 11, and the plurality of industrial cameras 7 face different positions. The specific construction conditions around the rolling device are obtained by the industrial cameras 7 in different directions and provided to the backstage personnel for operation, enabling remote operation.

[0032] The vehicle frame 1 also integrates a processor 12, a remote communication module 13, and a storage battery 14 that supplies power to the image acquisition mechanism, the remote communication module 13, and the processor 12 respectively. The processor 12 is electrically connected to the traveling mechanism 8, the image acquisition mechanism, and the remote communication module 13 respectively. The processor 12 can be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The communication module is specifically a GSM communication module or a WCDMA communication module.

[0033] The hydraulic lifting mechanism includes a lifting main shaft 4 and support sub-shafts 5 arranged on both sides of the lifting main shaft 4. In specific use, the present utility model lifts the rolling roller 2 through the combined action of the lifting main shaft 4 and the support sub-shafts, thereby improving the passability and flexibility of the vehicle.

[0034] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
