Abstract
Description
Technical Field
[0001] The utility model relates to the field of road rollers, in particular to a safety distance alarm device for a paving and rolling machine. Background Art
[0002] A road roller is a structure for leveling asphalt or water-stabilized road surfaces. In the prior art, the main components of a road roller are a power part and a road roller part. The road roller part is a huge barrel-shaped structure, which is pushed and controlled by the power part, i.e., the cockpit. However, the drum of the road roller is large in size and it is easy to form a visual blind spot in the direction of travel of the road roller. If the construction workers do not evacuate in time during construction or there are other construction equipment in front of the road roller, they are easily crushed by the road roller, posing a safety hazard.
[0003] According to the published patent 202223299477.3, a safety distance alarm device for paving and rolling machinery includes a power connecting frame, which is rotatably connected to a roller through a connecting shaft, and a number of evenly distributed sensing structures are arranged in sequence on the side of the power connecting frame away from the roller. When the sensing structure collides with people or equipment that have not been evacuated, the flashing lights are controlled by the pressure sensor, so that the corresponding flashing lights flash as a warning, reminding the driver of the press to brake in time, so as to achieve a warning to maintain a safe distance. The sensing device includes a number of pressure sensors and a sensing alarm. According to the utility model, when a person or equipment enters an unsafe distance of the roller while the press is being driven, the flexible rod touches the staff or equipment, causing the connecting column to squeeze the pressure plate, causing the pressure plate to squeeze the pressure sensor, causing the flashing light to flash, reminding the driver to stop the car in time, avoiding safety hazards, and making paving and rolling safer. 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 by setting the sensing structure, when a person or equipment enters an unsafe distance of the roller while the press is being driven, the flexible rod touches the staff or equipment, causing the connecting column to squeeze the pressure plate, causing the pressure plate to squeeze the pressure sensor, causing the flashing light to flash, and reminding the driver to stop the car in time, avoiding safety hazards, and making paving and rolling safer. The sensor makes the flashing light flash, reminding the driver to stop the car in time to avoid safety hazards, making paving and rolling safer. It solves the problem that the roller of the roller is large and easily forms a visual blind spot in the direction of the roller. If the construction workers do not evacuate in time or there are other construction equipment in front of the roller, they are easily crushed by the roller, which poses a safety hazard. However, during use, the safety distance alarm device of the traditional paving and rolling machinery uses a pressure sensor for pressure sensing alarm. This sensing alarm method requires touching the workers, which is dangerous and poses a safety hazard. Moreover, during the paving and rolling process, there is a situation where the paving and rolling is uneven. For this reason, it is necessary to design a new technical solution to solve it.

This type of sensing alarm method requires touching the staff, which is dangerous and poses a safety hazard. Moreover, during the paving and rolling process, there is a technical problem of uneven paving and rolling.
