Abstract

The invention discloses a method for replacing a straddle type monorail tension support hinged shaft, which comprises the following steps: separating a lower hem of a support from a shear tenon, and releasing the fixation of the lower hem of the support; jacking the track beam by a preset height; the anti-disengaging plate of the hinged shaft is detached, the hinged shaft is clamped and connected with a jacking and stretching mechanism, and the hinged shaft is pulled out through traction of the jacking and stretching mechanism; and the new hinge shaft is pushed into the shaft holes of the support upper pendulum and the support lower pendulum and is fixed. According to the method for replacing the hinged shaft of the straddle type monorail tension support, the hinged shaft of the straddle type monorail tension support can be replaced and maintained, potential safety hazards are eliminated in time, and safe operation of a track is guaranteed.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a method for replacing a hinge shaft of a straddle-type monorail tension support. Background technique [0002] Monorail traffic is a rail transit system in which vehicles use rubber tires and run on a track beam that combines beams and rails. Vehicles straddle the track beam and run on it, which is called straddle-type monorail traffic. The track beam is connected with the substructure (pier column, cover beam) through the tension support to form a monorail bridge system. The straddle-type monorail tension support is fixed above the cover beam and supports the track beam. The straddle-type monorail tension support includes the upper swing of the support, the lower swing of the support and the shear tenon fixed to the cover beam to limit the lower swing of the support. For the fixed support, the upper swing of the support and the lower swing of the support pass through Hinge ...
