The invention discloses a comb type bridge expansion device with adaption to multi-directional displacement and relates to the technical field of bridge expansion joints. The comb type bridge expansion device comprises a fixed comb plate and a movable comb plate which are connected with a first bridge body and a second bridge body respectively, and is characterized in that the movable comb plate and the second bridge body are in limit connection by the aid of an upper bracket plate, a lower bracket plate and a universal joint structure arranged between the two bracket plates. The comb type bridge expansion device has the benefits as follows: multi-directional displacement of the expansion device is realized through a vertical shaft and a horizontal shaft, the requirements for a vertical rotation angle in the longitudinal bridge direction and a plane rotating angle in the horizontal bridge direction of the movable comb plate are met, and received vertical load is transferred to the upper bracket plate through the movable comb plate and then transferred to the lower bracket plate and a abutment bearing surface through a cylindrical stress bearing surface of the upper bracket plate; the requirement for the vertical rotating angle in a vehicle traveling direction is met by the horizontal shaft which connects the upper and lower brackets; the vertical shaft between the lower bracket plate and one bridge body adapts to the horizontal rotating angle in the bridge width direction and plane displacement caused by mounting deviation.
