Background

The backstop is also called car arrester, triangular wood, antiskid triangular wood, etc. The anti-sliding device is generally arranged below wheels, limits vehicles to stop at a specified position on one hand, is used for preventing sliding accidents on the other hand, and is often matched with equipment such as a car pusher, a car dumper, a climbing car, a tank car and the like.

In the field of petrochemical industry, a tank truck is often used for transporting petrochemical products, and a backstop is used for preventing vehicles from moving when dangerous goods (oil products and chemical products) are loaded and unloaded by the tank truck. According to the safety requirements, before a tank car is loaded and unloaded, a driver needs to place a backstop device below the front and the back of a tire, so that the vehicle cannot move back and forth, but sometimes the backstop device is not placed in place due to negligence of the driver, so that the tank car has a car sliding accident, and the safety accident is caused. In the process of loading and unloading the tank truck, if the backstop device is not placed in place, the loading and unloading pipeline can be torn off if the truck moves, and the loading and unloading medium overflows to cause safety accidents. After the loading and unloading of the vehicle are finished, if the backstop device is not timely moved away from the front and the rear of the wheel, the vehicle is difficult to drive out, if the vehicle is driven out by force and is light, the backstop device is crushed, and the vehicle is seriously even overturned.

Patent document (patent number: CN202020838996.4) discloses a detection device of intelligence suggestion backstop ware position, including casing, cable that have the through-hole and pivot, carousel, detection device of setting in the casing, the cable passes the through-hole and links to each other with the carousel, the carousel sets up in the pivot, be provided with two check points on the carousel, before the tank car loading and unloading car, can detect whether the backstop ware is placed relevant position and whether playback through sensor induction magnetic field reciprocating variation, carousel pivoted number of turns and direction, can indicate and output chain signal, prevent unexpected emergence, the favorable safety of protecting personnel and on-the-spot property.
