Technical Field
[0001] This utility model relates to the field of hazardous chemical transportation technology, specifically to a rear protection device for a hazardous liquid transport vehicle. Background Technology
[0002] The transportation of hazardous liquid chemicals is a highly specialized logistics service that involves the use of specialized vehicles and strict operating procedures to ensure the safety and stability of various flammable, explosive, toxic, or corrosive liquids during transportation, and to avoid potential harm to personnel, the environment, and property.
[0003] In the existing technology, simple guardrails are usually installed at the rear of transport vehicles. However, in the event of an accident, especially when the transport vehicle is stopped and rear-ended by a car, the car may crash into the bottom of the transport vehicle, posing a danger to people and the surrounding environment. Utility Model Content
[0004] The purpose of this utility model is to provide a rear protection device for hazardous chemical liquid transport vehicles, so as to solve the problem in the prior art that when a hazardous chemical liquid transport vehicle is in a stopped state and is rear-ended by a car, the car may crash into the bottom of the transport vehicle, posing a danger to people and the surrounding environment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rear protective device for a hazardous chemical liquid transport vehicle, comprising two connecting rods for installation on the vehicle body, an equipment frame rotatably mounted between the two connecting rods, a protective plate fixedly mounted on the equipment frame, two grooves formed on the surface of the protective plate, the two grooves being symmetrically arranged along the central axis of the protective plate, a baffle slidably connected within the groove, a buffer and shock absorption mechanism installed between the baffle and the groove wall, a sliding groove formed on the connecting rod, a slider provided within the sliding groove, a connecting chain installed between the slider and the protective plate, and a positioning pin for fixing the position of the slider within the sliding groove.
[0006] As a preferred technical solution of this utility model: the buffer and shock absorption mechanism includes a tube body, which is fixedly installed on the groove wall. The number of tube bodies installed on each groove wall is four, and the four tube bodies are evenly spaced. A limit rod is slidably connected inside the tube body. A spring is fixedly installed between the end of the limit rod inside the tube body and the inner wall of the tube body. The other end of the limit rod is fixedly connected to a baffle.
[0007] As a preferred technical solution of this utility model: a circular groove is provided at the top of the protective plate, an electric telescopic rod is fixedly installed in the circular groove, and a baffle plate is fixedly connected to the end of the electric telescopic rod.
[0008] As a preferred technical solution of this utility model: a fixing rod is installed between the two connecting rods.
[0009] The beneficial effects of this utility model by adopting the above technical solution are as follows: This utility model has a simple structure and ingenious design. During the operation of the transport vehicle, by raising the protective plate, the protective plate forms an isolation and protection for the tank on the transport vehicle. When a rear-end collision occurs or the transport vehicle reverses and collides, the baffle on the protective plate can play a buffering and anti-collision role. When the transport vehicle stops, by lowering the protective plate and causing the electric telescopic rod to extend the baffle, the baffle and the protective plate can simultaneously play a blocking role for the following vehicle, preventing the following vehicle from rushing under the vehicle and causing personal injury, and further reducing the risk of accidents.
