Bottom Dumping Mine Car Principle
A transportation tool for moving coal, ore, waste rock and material in the process of mining, dragged by a locomotive or winch.
Bottom Dumping Mine Car Structure
Bottom Dumping Mine Car Structure
Mainly consits of carriage, frame, buffer device, open-wheel set, connection device, bottom dumping menchanism, etc.
Carriage:Mechanical and physical properties of the material is not less than Q235-A steel. Technical conditions are in accordance with the provisions of the JB/T6992-1993.
Steel Material before welding should be straight, surface flatness shall not exceed 3 ‰, but the maximum must not exceed 6mm.
Metal structure frame, which can withstand the traction. Welded by channel steel, shaft card. Technical conditions are in accordance with the provisions of the JB/T6992-1993.
Frame sides parallel degree of tolerance for the length of 2 ‰.The flatness tolerance of the flame is 2 ‰ to the frame length (buffer not included ), but the max flatness tolerance should less than 5 mm.
The center plane of the frame traction device should be symmetry to the longitudinal center plane of the frame, and its symmetry tolerance should not exceed 6mm.
Wheel Set
Open-wheel Set: wheel, axle , axile bearung. Technical conditions execute JB/T6992-1993.
Before wheel set assembly ,should clean the iron filings and blockage and cleaning all parts; during bearing assembly, should adopt no shock load method; After loading bearing, wheel rotation should be flexibility.
Buffer Device
Bumper technical conditions in accordance with JB/T6992-1993
Buffer has enough strength, cushioning material toughness value of not less than 30J/cm2,cast steel bumpers there shall be no crack, on the surface of cast steel bumper bolt hole.
Connection Device
Connection device is composed of connection three-ring chain, bolt.
Connection three-ring chain conforms with the standard requirements of" MT 244.1 - 2005 coal mine narrow gauge vehicle fittings connection chain ".
Assemble Requirements
Before assembling,all the parts should be inspection qualified.
All parts should be clean, and assembly in a clean environment.
Assembled dimension deviation: the total width of mine material car and the high traction deviation of ± 3 mm, total high deviation of ± 8 mm, length deviation of ± 10 mm.
Deviation of the length of the material mine car of - 10 ~ 0 mm, width deviation of plus or minus 3 mm.
Assembled mine material car should be placed in a special flat road inspection,and a larger than 2mm gap on the surface of the wheel and rail is not allowed.
Bottom Dumping Mine Car Installation and Commissioning
Preparation
Before assembling,all the parts should be inspection qualified.
All parts should be clean, and assembly in a clean environment.
Assembled dimension deviation: the total width of mine material car and the high traction deviation of ± 3 mm, total high deviation of ± 8 mm, length deviation of ± 10 mm. Deviation of the length of - 10 ~ 0 mm, width deviation of plus or minus 3 mm.
Installation
Make sure wheel set center line coincides with the centerline of the track.
Commissioning
Observe whether the wheels rub on the track,handle it in time to prevent damage once the phenomenon occurs.
Observe whether tilt,out of orbit or overturned after it sliding along the slope curve and colliding with another car.
Observe the runing codition on the minimum radius of curvature of the track.
