Product Description

Main uses
1. Connect and fix
The pins pass through the connecting rings or traction devices of the mine cars, connecting multiple mine cars in series to form a train set and creating a stable transportation unit.
Prevent the mine car from disconnecting due to jolting, tilting or collision during operation.
2. Safety locking
Some of the pins are designed with lock holes or spring clips, allowing for the insertion of split pins or the addition of safety devices to prevent the pins from falling off by themselves.
It is particularly important when transporting in inclined shafts or slopes to prevent the mine car from slipping due to the effect of gravity.
3. Quick disassembly and assembly
It is convenient for manual or mechanical operation, allowing for quick separation of mine cars during loading and unloading, grouping or maintenance, thereby enhancing work efficiency.

 

Usage scenarios
Underground rail transportation
It is used to connect underground track mine cars (such as fixed mine cars, dump trucks, flatbed trucks, etc.) in coal mines, metal mines, etc., and transport ores, waste rocks or equipment.
2. Ground storage yards and mineral processing plants
In ore storage yards and mineral processing assembly lines, pins are used for short-distance transportation of mine cars or fixed parking of vehicle groups.
3. Inclined shaft and slope transportation
When transporting in inclined tunnels or on slopes, pins with safety devices should be used to ensure safety when heavy loads go downhill.
4. Mine locomotive traction
When the electric locomotive and winch pull the mine car group, the pins need to withstand the traction force and impact force, and high-strength materials (such as alloy steel) should be selected.

 

Common types
1. Ordinary straight pin
Cylindrical steel pins, with a simple structure, need to be fixed in combination with split pins and are suitable for low-load scenarios.
2. Spring pin
It is equipped with a built-in spring retaining ring. Once inserted, it automatically locks without the need for additional fixation, making the operation convenient.
3. Anti-disengagement pin
Equipped with a locking ring or secondary safety structure, it is used in high-risk areas.
4. Heavy-duty latch
Thickened design, made of high-strength alloy steel, suitable for large-tonnage mine trucks or working conditions with frequent impacts.

 

The mine car pin is an important component in the mine transportation system used to connect mine cars. It is mainly used to fix and lock the connection devices (such as chain links, traction rods, etc.) between mine cars, ensuring the stability and reliability of the mine cars during transportation and preventing decoupling or accidental separation.
