Problems solved by technology
[0004] Since asphalt is in a solid state at room temperature, it must be heated to a certain high temperature to thin the asphalt at high temperature and then spray it out from the spray port at the rear of the vehicle. During road maintenance work, it was found that the asphalt distributor has a low degree of intelligence when spraying. , the rear lacks the necessary safety sensing equipment. When the road maintenance workers are working on the rear of the vehicle, the asphalt liquid sprayed out at high temperature will pose a great safety hazard

Embodiment 1
[0015] Such as figure 1 as shown, figure 2 The shown asphalt gear pump 2 is installed behind the asphalt spreading vehicle 1, the safety sensor 2.1 is installed directly behind the asphalt gear pump 2, and the shutdown machine 2.2 is connected in series with the safety sensor 2.1. When the safety sensor 2.1 senses that the rear construction workers enter the warning distance, it will send an alarm message to the shutdown machine 2.2 in time to stop the sprinkler, so as to prevent the construction workers from being scalded by the sprayed high-temperature asphalt liquid, and improve the safety of road construction work.

An asphalt spraying car stopping device is composed of an asphalt gear pump 2, a safety sensor 2.1 and a stopping machine 2.2. The asphalt gear pump 2 is installed behind an asphalt spraying car 1; the safety sensor 2.1 is right installed on the rear portion of the asphalt gear pump 2; and the stopping machine 2.2 and the safety sensor 2.1 are connected in series. When the safety sensor 2.1 senses that a constructor behind enters the alert distance, alarm information is sent to the stopping machine 2.2 in time, a spraying device stops working, sprayed high-temperature asphalt liquid is prevented from scalding the constructor, and safety of the road construction work is improved.
Description
technical field [0001] The invention relates to a safety distance sensing device used when spreading asphalt vehicles. Background technique [0002] The asphalt distributor is a kind of road construction machine, which is the main equipment for the construction of highways, urban roads, airports and ports. When using the asphalt penetration method and asphalt layer surface treatment method to build asphalt pavement or maintain asphalt or residual oil pavement, the asphalt distributor can be used to transport and spread liquid asphalt (including hot asphalt, emulsified asphalt and residual oil): In addition, it can also supply asphalt binder to the locally loosened soil, and build asphalt stabilized soil pavement or pavement base. [0003] It can also be used to implement the anti-interference ability of layered paving equipment for the asphalt spreading of the permeable waterproof layer bonding layer of the bottom layer of the asphalt pavement of high-grade highways, asphal...
