The invention relates to a contact catenary guide type suspension pulley device. Common suspension pulleys used at present are connected in a hinged mode, parts are severely abraded due to long-term wind induced oscillation, the abrasion rate of bolt limiting pins is 60% after observation is performed in a site for two years, and through holes of part bodies severely deform. The contact catenary guide type suspension pulley device comprises a U-shaped pulley frame with a downward opening, wherein a pair of parallel connecting lugs is upwards arranged on the top face, corresponding through holes are formed in the two connecting lugs, and self-lubricating bearings fitted in an interference mode are embedded into the through holes. An upper axially-horizontal guide wheel and a lower axially-horizontal guide wheel are arranged in the pulley frame and are installed on the pulley frame through hinge pins. The middles of the guide wheels are concave, and an empty groove for a lead to penetrate through is formed between the upper guide wheel and the lower guide wheel. The contact catenary guide type suspension pulley device can be automatically adjusted according to the stress direction of the lead and has the effects of free movement with temperature change and accurate guidance, frictional abrasion among the parts can be effectively reduced through the self-lubricating bearings fitted in the interference mode of the two connecting lugs, and the service life of the contact catenary guide type suspension pulley device is prolonged.
