Abstract
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.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
Electrified railway wind district contact system terminal adopts to prolong and casts anchor across branch, and catenary transition on adjacent bracket is hung, and transition is hung and adopted suspension pulley device, can vary with temperature free play, does not affect the deflection of another work supporting power rope bracket.When the present invention can solve that in wind district, AT power supply mode additive wire AF identical tension charging system is arranged, hitch point place hangs AF line.Headspan suspension place can replace former common suspension pulley to hang catenary.
The common suspension pulley of current use adopts the mode that is articulated and connected, and long-term wind pendulum serious wear between parts, through field observation bolt position-limitting pin wearing and tearing 60% after 2 years, the distortion of parts body through-holes seriously.Common pulley is used for suspension when prolonging across catenary, there occurs pulley body and rotates to bracket upper end, wire eccentric wear wheel body, and position-limitting pin to come off etc. and happens occasionally.
The contact system guide type suspension pulley device that the present invention relates to, adopts two restriction assembly pulley, has suspension, accessible play and the function such as anti-wear.Structure includes and takes the shape of the letter U and the guide roller frame 2 that Open Side Down, and guide roller frame 2 is made up of the connecting panel that the frame plate that two panels is parallel to each other is vertical with the two with two panels frame plate top.
The connecting panel end face of guide roller frame 2 is upwards provided with pair of parallel connection ears 1, connect on ears 1 and offer corresponding through hole, ears are embedded in interference fit self-lubricating bearing, be articulated and connected swingable in horizontal path with attaching parts, can effectively alleviate the friction relatively rotating generation between parts, avoid earhole, yoke plate earhole, bolt pin etc. to be rubbed to come off, eliminate operation security hidden danger.
Be provided with the track adjusting wheel 3 of upper and lower two axial levels in guide roller frame 2, be installed on guide roller frame 2 by bearing pin 4, the end that bearing pin 4 is positioned at outside guide roller frame 2 is tightened up by spring cotter 5, nut 6 and bullet pad 7.The outer interference fit that embeds of the bearing pin 4 of track adjusting wheel 3 has self-lubricating bearing 9.In the middle part of track adjusting wheel 3 recessed time, form the dead slot through wire between upper and lower two track adjusting wheels 3, wire is between upper and lower track adjusting wheel 3, and upper and lower track adjusting wheel 3 is driving wheel, wire retractable and play.
