Jointed coldproof rack railway system with braking feature

Abstract

The present invention relates to a jointed coldproof building rack railway system with braking feature, comprising a number of jointed rack rails fixed to a building, connection components for connecting the rack rails together, a lift device and a number of electrically heated infrared ice melting device. An installation plate is disposed at an inner side of the rack rail, a rail plate is disposed at an outer side of the rack rail, connection poles are disposed at four peripheral locations of the rack rail. Two rows of rack teeth are uniformly and vertically disposed on the rail plate. A connection hole is disposed at the connection pole for mounting the connection components. A limiter stand is disposed at a central portion of the connection component, bolt holes are disposed at a top portion and a bottom portion of a side wall of the connection component. Through holes are disposed at a side wall of the connection hole for allowing bolts to penetrate through and correspond to the bolt holes. The rack railway system of the present invention has the advantages of being reasonable, vertical movement is safely controlled, preventing rail from being unable to use due to freezing rails, increasing maintenance efficiency.
