AI Technical Summary

Technical Problem

Existing technologies suffer from space constraints, construction difficulties, and low efficiency during the installation of hot-rolled transport chain track beams, especially in the time-consuming and labor-intensive process of removing and reinstalling bearings, and the tight construction schedule.

Method used

By using a chain hoist and overhead crane, the conveyor chain is fixed at both ends and the intermediate bearing is removed. The conveyor chain is then stacked using the overhead crane, and seamless steel pipes are welded to both sides of the track beam for fixation. This enables rapid replacement of the track beam and efficient reinstallation of the conveyor chain.

Benefits of technology

This reduced the amount of bearing disassembly and assembly work, avoided manual motor operation, shortened the construction cycle, improved construction efficiency, and saved resources and time.

Abstract

The application discloses a method for installing a hot-rolled conveying chain track beam, removing cover plates on both sides of the conveying chain and on the conveying chain at a bearing to be removed, cutting off fixing bolts of the track beam; applying a chain hoist to fix both ends of the conveying chain on a frame, locking the conveying chain, and removing middle bearings; applying a crown block to stack the conveying chain to both sides, and fixing the conveying chain; moving the track beam to be removed out, and cleaning around the track beam; moving a new track beam into a corresponding position, checking a track bottom plate, fixing the new track beam after the track bottom plate meets the requirements; reinstalling the conveying chain from both ends to the middle, and reinstalling the bearings; removing the chain hoist, and reinstalling ground cover plates on both sides of the conveying chain and the conveying chain cover plates. The method greatly reduces the engineering quantity of bearing dismounting and mounting, reduces the demand for the crown block, saves resources for normal production of other production lines, and greatly shortens the project construction period.
