The invention relates to an elevator brake releasing device. The elevator brake releasing device comprises a first brake, a second brake, a first support and a second support, wherein the first brake and the second brake are symmetrically arranged on an elevator host. The elevator brake releasing device further comprises a control rope, an outside well releasing operating mechanism used for tensioning or releasing the control rope, a first pull rod and a second pull rod, wherein the first pull rod and the second pull rod are arranged in a crossed mode. One end of the first pull rod is rotationally connected with the first support, and a pulley is connected to the other end of the first pull rod. The first pull rod is provided with a movable groove. One end of the second pull rod is movably connected with the second support. The other end of the second pull rod penetrates through the movable groove and is connected with one end of the control rope. The other end of the control rope winds around the pulley to be connected with the outside well releasing operating mechanism. The first brake and the second brake are connected with the first pull rod and the second pull rod respectively. According to the elevator brake releasing device, releasing is carried out in a mechanical mode, the problem of failure of the releasing device due to electric failure can be solved, and safety and reliability are achieved. The first pull rod and the second pull rod are arranged in the crossed mode, the synchronism of releasing of the first brake and the second brake is high, and brake force is stable.
