Coal mine underground track turnout is an important part of the underground transportation system of coal mine, and it plays a vital role in the coal mining process.
The quality and performance of the turnouts directly affect the efficiency and safety of coal mine transportation.
This article will provide an in-depth analysis of the characteristics, structure and application of underground track turnouts in coal mines, and enrich their related content to help readers better understand this field.
1. Characteristics of underground track turnouts in coal mines1Large load capacity:
The trains carried by underground track turnouts in coal mines are often heavier, so the turnouts need to have sufficient carrying capacity to ensure the stability and safety of transportation.
2.Strong abrasion resistance:
Due to the particularity of the underground coal mine environment, the turnout is susceptible to wear and tear under high-intensity transportation, so it is necessary to use wear-resistant materials for structural design.
3.High Reliability:
Underground coal mines are often a complex and dangerous working environment, and turnouts need to have high reliability to cope with various emergencies and abnormal situations.
4.Easy to install and maintain:
The underground space of coal mines is small, and the installation and maintenance of turnouts need to be convenient and efficient to reduce the work intensity and time cost of workers.
Second, the structure of the underground track turnout in the coal mine 1Sleepers:
The main support structure of the turnout, which is generally made of steel.
It is attached to the track and plays the role of supporting and fixing the turnout, carrying the weight of the train.
2.Wing rails: Rails connected to sleepers that have high compressive and abrasion resistance and are able to withstand the forces from the train.
3.Heart rail: The central rail connected to the wing rail and connected to the sleeper, which plays the role of diversion and guidance.
It is designed to allow the train to steer smoothly as it passes through the turnouts.
4.Sharp rail: At the tip of the turnout, the guide wheel used to guide the train into the correct track to ensure that the train passes through the switch safely.
Third, the application of underground track turnouts in coal mines 1Transport system:
Underground track turnouts are widely used in underground coal mine transportation systems, mainly used to connect different wellheads, roadways and roadway intersections.
The turnout transports coal from the coal mining area to the wellhead through a branch road, further realizing the transportation and stacking of coal.
2.Downhole Equipment Maintenance:
Coal mine underground turnouts can also be used to repair and maintain equipment, which is convenient for staff to replace, adjust and repair equipment.
Coal mine underground track turnouts are an indispensable and important part of the coal mine transportation system.
It has the characteristics of large bearing capacity, strong wear resistance, high reliability and easy installation and maintenance, and is widely used in the transportation system and equipment maintenance of coal mines.
Through an in-depth analysis of its characteristics, structure and application, we are able to better understand and grasp the importance and use of underground switches in coal mines.
Doing a good job in the design, installation and maintenance of underground turnouts in coal mines will help improve the safety and efficiency of coal mine transportation.
