Description

Technical Field

[0001] The utility model relates to the field of road rollers, in particular to a safety protection frame for road rollers which is convenient to disassemble. Background Art

[0002] At present, whether it is a single steel wheel, double steel wheel or rubber wheel roller, the sight range is small and it is easy to have visual blind spots. In the construction of infrastructure such as roads, railways, aviation, and water conservancy, rollers are widely used and appear in clusters. During the construction of rollers, there must be manual assistance in shoveling materials and cleaning rollers. There are many types of related machinery in the construction process, and there are intensive cross-operations. There is no effective protection warning system for the blind spots of the roller driver's vision. The roller itself either has no protective frame or has very simple safety protection, which does not provide effective safety protection at all. On-site construction workers are often hit and crushed by rollers, and the probability and risk of serious injuries and deaths are very high.

[0003] According to the public patent 201921910264.5, a foldable road roller safety protection frame that is easy to disassemble, the movable frame is connected to the lower end of the fixed frame; the fixed frame includes an outer support rod, an upper cross rod, a vertical rod I and a vertical rod II. The fixed frame is a square frame, and the movable frame includes a lower gear rod, a vertical rod III, a guide rod, a vertical rod VI and a connecting rod. The guide rod is connected to the vertical rod I, the connecting rod is connected to the vertical rod II, the vertical rod III and the vertical rod VI are connected to the upper end of the lower gear rod, the vertical rod III is rotatably connected to the lower end of the guide rod, and the vertical rod VI is rotatably connected to the lower end of the connecting rod; the structure of the utility model It is scientific and reasonable, simple to operate, easy to disassemble and assemble, effectively prevents the occurrence of safety accidents, improves the safety and reliability of roller construction, is applicable to various types of rollers, can be reused, reduces capital investment, and has promotion value. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved, although it is simple to operate, easy to disassemble and assemble, effectively prevents the occurrence of safety accidents, improves the safety and reliability of roller construction, is applicable to various types of rollers, can be reused, reduces capital investment, and has promotion value. With the help of radar probes and cameras, drivers can find obstacles ahead as early as possible, eliminate the driver's visual blind spots, further avoid accidents, and improve safety and stability. It solves the problem that there are many related machines in the construction process, there are intensive cross-operations, and there is no effective protection warning system for the blind spots of the roller driver's vision. The roller itself either has no protective frame or is a very simple safety protection, which does not provide effective safety protection at all. On-site construction workers are often hit and crushed by rollers, which results in high probability and risk of serious injuries and death. However, during use, the traditional roller safety protection frame is easy to disassemble and has multiple rods, which need to be disassembled and assembled. It is not very convenient and the disassembly efficiency is relatively low. Moreover, although radar and cameras are installed, the camera position is limited, resulting in blind spots. When workers or equipment are in the blind spots, collision accidents will still occur. Therefore, a new technical solution needs to be designed to solve the problem. Utility Model Content
