Bearing hinge point for counterweight crane and maintenance method thereof

Abstract

A bearing hinge point for a counterweight crane and a maintenance method thereof, the bearing hinge point includes two bearings, and the two bearings are axially fixed in the mounting hole of the bearing seat through the bearing end cover; the bearing The hinge point also includes a fixed support fixed on the base, the left side bearing support and the right side bearing support are fixed on the fixed support in a detachable manner, and the bearing hinge point is also provided with a bearing connecting the left side bearing support. Connection piece for the seat and the right side bearing support. When it is necessary to replace or repair the bearing, first fix the base and the balance beam; then remove the bearing support and bearing end cover on the side with the damaged bearing, and replace the bearing on this side; finally, replace the disassembled bearing support, Replaced bearings and bearing end covers are reinstalled in place, and the support rods are removed. The hinge point of the above-mentioned bearing has a relatively simple maintenance process and little potential safety hazard.

Description

technical field [0001] The invention relates to a bearing hinge point used in heavy machinery, in particular to a bearing hinge point which is convenient for maintenance. Background technique [0002] In a counterweight crane, a bearing is provided inside the bearing housing of the hinge point of the bearing to bear the torsion force generated during the swing of the balance beam. For cranes with dynamic balance counterweight, the weight of the balance counterweight is often relatively large, which will cause a great impact on the hinge point of the bearing during frequent back and forth operation; and most counterweight cranes have the function of rotation, The bearing hinge point also bears huge torsion force during the rotation process, so the bearing failure rate of the bearing hinge point is relatively high. [0003] At present, the bearing seat of the bearing hinge point is generally fixed on the balance beam by welding or bolting. When the bearing of the bearing hing...
