Belt conveyor is ground and underground coal mine coal transport system’s
main transportation equipment, for a long-distance transport capacity, transport
capacity and operating reliability and high efficiency. Drum is the main belt
conveyor components, the service life of roller conveyor seriously affected the
normal operation and production.
The use of a coal mine in Gansu Province
DSJ120-belt conveyors, work, a bend of the web seam roller several times and
multiple cracks, the worse a web cracking phenomenon, which has seriously
affected the production. In the detection and repair, from the force structure
and drum-pronged approach, the analysis of the reasons for cracking, and the
structure and process in an improved, improving methods of other belt drum
machine maintenance and repairs also have reference.
Drum can be divided
into force by driving drum and bend drum, drum drive transmission is based on
the principle of friction, will drive organic link with the conveyor belt to
complete the energy transfer between the two tasks, and ensure the reliable
operation of the conveyor . Bend roller conveyor system is used to change the
direction of the farewell, due to a change in direction from the conveyer belt
carrying the take-up pressure
An increase of holes to eliminate thermal
expansion cracking.
b. In a roller inside the vertical layout of the axial
direction of strengthening the roundabout, to enhance the strength of
drum.
c. welded steel castings and steel structure to combine structural
welding, welding to reduce stress, improve their overall strength.
d. bearing
modified in the cylinder, the overhaul will no longer shell and the
disintegration of axis, a decrease of the cylinder and shaft damage, while
providing a convenient for maintenance.
e. drum increase the thickness of the
plate and improve manufacturing quality and ensure drum intensity.
⑵ improve
welding process, welding quality assurance
⑶ strengthen safeguard and enhance
drum life, such as the workplace kept clean and ensure that cooling conditions;
does not allow roller conveyor belt along the slippery, found an immediate
relaxation of tension.
⑷ regular maintenance to ensure reliable
operation.
With its high quality products such as , , , Vibrating screen, , Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
