Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of mine trackless rubber -tyred vehicle driving protection, relates to a kind of mine driving safety protection device filled with nano energy absorption module. BACKGROUND

[0002] With the continuous progress of modern coal mining technology and the significant improvement of production capacity, as a key component in the auxiliary transportation system of coal mine, trackless rubber-tyred vehicle is increasingly widely used. These vehicles not only bear the heavy responsibility of safe and efficient transfer of personnel in coal mine, but also shoulder the important mission of material transportation, and have an irreplaceable role in ensuring the continuity and efficiency of coal production. Trackless rubber-tyred vehicle wins wide recognition and praise with its outstanding transportation efficiency, excellent safety, high practicability and fast response capability.

[0003] However, similar to conventional ground vehicles, most current trackless rubber-tyred vehicles still rely on manual braking systems to ensure driving safety. Although this braking method can effectively function in most cases, it faces many challenges in the special and complex environment of coal mine underground. The variable slope of the roadway, narrow width, unstable foundation conditions and limited light greatly increase the difficulty of trackless rubber-tyred vehicle operation and braking. In addition, subjective factors such as the technical level of the operator and the maintenance condition of the vehicle may also cause the braking system to malfunction or the operator to make mistakes.

[0004] Once these potential safety hazards occur, they often cause serious auxiliary transportation accidents, not only causing economic losses, but also posing a serious threat to the life safety of coal mine workers. Therefore, how to improve the braking performance and operation safety of trackless rubber-tyred vehicles in the complex environment of coal mine underground has become an important issue to be solved in the field of coal mine auxiliary transportation. In the future, with the continuous progress and innovation of technology, the safety and reliability of trackless rubber-tyred vehicles will be further improved, providing a more solid guarantee for the safety production of coal mine.

[0005] In order to ensure the safety of trackless rubber-tyred vehicle auxiliary transportation, some coal mines choose to place sand barrels beside the roadway and hang tires on the wall to buffer and absorb energy for out-of-control trackless rubber-tyred vehicles, which has poor energy absorption effect and poor protection effect. Even if a rotating barrel guardrail is installed, it can still cause serious injury to personnel in the case of poor buffering and energy absorption effect. Therefore, it is very necessary to develop a safety protection structure filled with a layer of flexible energy-absorbing material with high energy absorption, which can significantly weaken and buffer the transverse and longitudinal stress on the driver and passengers, greatly reducing the damage degree of trackless rubber-tyred vehicle accidents.
