Provided is a rigid overhead contact catenary temperature compensation device. The outer end of a left sliding guide rail and the outer end of a right sliding guide rail are respectively connected and fixed to bus bars at two ends. Sliding ways and sliding rails are arranged on the inner side faces of the two sliding guide rails in the whole length direction, and the two sliding guide rails are connected together by inserting sliding rails into the sliding ways formed in opposite side and can freely slide relatively. Contact wire clamping grooves are formed in the lower ends of the outer side faces of the two sliding guide rail in the whole length direction and correspond to contact wire clamping grooves formed in the lower ends of the bus bars connected with the sliding guide rails. Guiding supports are arranged on the top faces of the two sliding guide rails, guiding rods are fixed to parallel guiding seats, and the middle sections of the guiding rods penetrate into the parallel guiding seats on the opposite sides and can freely slide with the two sliding guide rails. The rigid overhead contact catenary temperature compensation device is installed in a rigid overhead contact catenary system, conducts compensation on thermal expansion and cold contraction produced by the system due to temperature change, achieves good electrical connection and smooth transition of anchoring sections, ensures that a locomotive operates stably and improves the operation safety and reliability of the locomotive.
