A method for installing a chain track

Abstract

The invention discloses a novel chain track installation method, which comprises the following steps: (1) marking the position of the track to be installed on a horizontal cross beam under an arch rib; B, arranging a track clasp and a track bracket at that marked position; C, lifting a track segment at the arch foot, connecting the track segment to the track support, adjusting a stretching mechanism, and connecting two adjacent chains into one body; D, hoisting a traveling mechanism and connecting the traveling mechanism to the track segment ; E, lifting a track laying base to be connected with the traveling mechanism; F, filling a track segment to be installed in a feeding mechanism when the traveling mechanism is operated to an arch foot; G, when the traveling mechanism runs to the trackarea to be installed and the feeding mechanism transports the track segment to be installed, receiving the track segment to be installed by a jacking mechanism, lifting the track segment to the trackarea to be installed to be connected to the corresponding track bracket, and adjusting the stretching mechanism to be connected to the two adjacent chains into one; H repeating steps F and G to forma complete chain track.

Description

technical field [0001] The invention relates to the technical field of bridge maintenance equipment, in particular to a method for installing a chain track. Background technique [0002] The inspection and maintenance of the arch ribs of the existing upper-supported steel truss arch bridges generally adopt the method of setting tracks on the lower parallel beams, and the tracks carry maintenance trolleys; the installation method of the tracks and the lower parallel beams is to set two A winch, the steel wire rope is arranged along the track installation axis to the mid-span and loops back to the arch foot to pull the hoisting area, and a pulley is installed at each lower parallel beam to fix the steel wire rope to protect the paint surface of the bridge. At the arch foot, use a car crane to install the arch first. At the foot of the track, the hoist is used to pull the track to the installation position, and the chain hoist suspended on the upper parallel is used to assist i...

[0002] The inspection and maintenance of the arch ribs of the existing upper-supported steel truss arch bridges generally adopt the method of setting tracks on the lower parallel beams, and the tracks carry maintenance trolleys; the installation method of the tracks and the lower parallel beams is to set two A winch, the steel wire rope is arranged along the track installation axis to the mid-span and loops back to the arch foot to pull the hoisting area, and a pulley is installed at each lower parallel beam to fix the steel wire rope to protect the paint surface of the bridge. At the arch foot, use a car crane to install the arch first. At the foot of the track, use the hoist to pull the track to the installation position, and use the chain hoist suspended on the upper parallel to assist in the installation of the track; this traction installation method requires a large investment in personnel and equipment, and the installation in the air takes a long time, which poses a greater threat to safety
