Recently, Shandong University of Science and Technology and Zhangzhou Mining (Group) Company Workers University have carried out technological transformation on the loading mechanism and walking mechanism of the S100 type roadheader on the basis of absorbing and digesting foreign advanced technology, and changed the original crab claw loading and centralized driving mode. Loaded for the star wheel and driven separately.
In the star wheel loading mode, the constant force of the dial makes the force of the system parts constant, greatly extending the service life of the parts; and because the left and right dials are driven separately, the driving force is greatly increased, so the star The technical production capacity of the wheel mechanism is larger than that of the finger grip mechanism. The new mechanism uses two radial low-speed motors to directly drive two star wheels, eliminating the need for a pawl reduction gearbox, simplifying the transmission mechanism and reducing the possibility of transmission failure. At the same time, the system can be adjusted by changing the number of teeth of the star wheel. The load is easy to match the production capacity of the equipment.
The track of the S100 type roadheader is seriously damaged in use due to the inherent defects of its complex combined structure, the processing and manufacturing of the domestically produced process and the material of the domestic track.
Advanced boring machines at home and abroad generally use the direct meshing of the drive sprocket and the track shoes to simplify the track sub-structure and adopt the overall track structure. The effect is better and the damage rate is lower. Therefore, when the design is improved, the drive is redesigned. The pitch diameter of the wheel is basically the same, to meet the interchangeability requirements. At the same time, the pitch is appropriately reduced, and the bending stress of the track is reduced. The driving teeth directly mesh with the track chain, and the track plate directly receives the force. The pin shaft only serves as a coupling, and the crawler plate is cast by using high-strength and high-abrasion material, which makes the meshing more stable and reliable.
The improved roadheader has high technical performance and reliable work, and achieves large benefits under small input to meet the needs of modern mine production.
