Mine Dispatch Winch uses oil as the working medium to transmit motion through changes in the seal volume. The Dispatch Winch drum will have abnormal noise during use. What should be done? Under the analysis of the manufacturer: the drum shell bolts are loose. The gap between the barrel and the support is too large. The drum casing is cracked. The fixing screws of the shell-welding swimming roller and the bushing are loosened, causing relative sliding between the swimming roller and the bushing. The gap between the bushing and the main shaft is excessively worn.
Treatment method: Determine the treatment method according to the hydraulic Dispatch Winch inspection. For loose nuts, etc., it can be tightened when the exchange class is stopped. If the sound is not serious, the Dispatch Winch load can be appropriately reduced. Observe and observe and maintain it until the scheduled shutdown. If the sound is severe, stop repairing or replacing it immediately to prevent the accident from expanding.
Installation of mine Dispatch Winch spindle unit and bearing beam installation bearing beam should be evenly installed around the bearing beam, the spacing should not be more than 600 mm, and the horn should be installed on both sides of the anchor bolt and below the bearing center; Liang Xian is on the basis of the requirement that the horizontality error along the axial direction of the main shaft does not exceed 0.15/1000, and the error perpendicular to the main axis direction does not exceed 0.3/1000. After the bearing beam is leveled, the diagonal horns of each group are intermittently welded. Hold the concrete after the spindle unit is installed.
The diagonal horns must be used in pairs. The slope of the horn should not be greater than 1/25, the thickness of the thin end should not be less than 5 mm, the thickness of the horn group should be 60-100 mm, and the width should be 60-120 mm. The roughness is not higher than; the spindle device assembly is placed on the bearing housing, and the following standard is achieved after alignment; the position deviation of the spindle shaft line relative to the installation reference line in the horizontal plane does not exceed L/2000, L system spindle axis The horizontal distance from the centerline of the wellbore lift.
