Mine roadway blocker is a kind of safety equipment widely used in mines, and its main function is to quickly stop and fix the transport vehicle when encountering abnormal conditions in the mine roadway, so as to protect the life safety of workers and the integrity of mine equipment.
1.Main Functions and Principles As a safety device, the main function of the mine roadway blocker is to quickly stop and fix the vehicle when danger occurs in the mine roadway to prevent accidents.
It usually consists of two main parts:
Fixtures and controls.
The fixtures are mainly made of steel and can be fixed to the roadway floor or side walls, connected to the vehicle by adjustable long poles and contact devices.
When the vehicle is in operation, the contact device pulls the long rod by friction, which keeps the fixture in close contact with the vehicle.
The control device is a key part of the mine roadway blocker, which is usually composed of springs, screws and limit switches.
When the mine roadway blocker detects that the vehicle speed is abnormal or dangerous, the control device will quickly release the spring energy to move the long rod in the direction of the vehicle, so that it can contact the vehicle and cause braking.
At the same time, the limit switch triggers an alarm system to notify the mine staff to deal with it.
2.Structure and Characteristics The structure of the mine roadway arrester is usually relatively simple, but its design takes into account the particularity and safety needs of the mine environment.
First of all, high-strength, wear-resistant steel is usually used in the selection of materials to ensure the durability and reliability of the mine roadway blocker in harsh environments.
Secondly, the size and weight of the mine roadway blocker are also precisely calculated and designed to be able to adapt to the size of the mine roadway and the load requirements of the vehicle.
In addition, the mine roadway blocking device also has a sensitive control system, which can detect the vehicle running speed, braking force and other relevant parameters in time to determine whether the vehicle blocking mechanism needs to be triggered.
3.Application Scenarios and Future Development DirectionsAs an important mine safety equipment, mine roadway car arrester is widely used in the mining industry.
It can effectively prevent accidents and protect the life safety of miners and the integrity of mine equipment.
With the advancement of science and technology and the development of the mining industry, the mine roadway blocker is also constantly improving and innovating.
For example, some new mine roadway blockers use intelligent technology, which can achieve more accurate vehicle speed detection and fault diagnosis through sensor and data analysis, and improve the safety and stability of the entire system.
In addition, the design and manufacture of mine roadway arresters also need to take into account environmental protection and energy saving requirements to reduce resource consumption and environmental pollution.
Therefore, in the future development, it is expected that the mine roadway blocker will continue to develop in the direction of being more intelligent, more efficient and more environmentally friendly.
To sum up, the mine roadway car arrester is an important equipment related to the life safety of miners and the stability of mine equipment.
Through the cooperation of fixtures and controls, it is able to quickly stop and immobilize the vehicle in dangerous situations and prevent accidents.
With the advancement of science and technology and the improvement of industrial demand, the mine roadway car arrester is also constantly innovating and developing to meet the needs of the mining industry in the future.
