The invention provides a rescue device for electrically lifting an elevator car after an elevator host and an internal contracting brake are broken. The rescue device comprises a mounting base, firstcompaction wheels, a slide base, second compaction wheels, a first driving device and a first rotation driving device, wherein the mounting base is arranged on the inner wall of an elevator shaft or aframe; the first compaction wheels are arranged on the mounting base, and can rotate relative to the mounting base; the slide base is arranged on the mounting base in a slide way; the slide directionof the slide base relative to the mounting base is a horizontal direction; the second compaction wheels are arranged on the slide base; the first compaction wheels and the second compaction wheels are used for clamping a steel wire rope in a matching way; the first driving device is connected with the slide base, and is used for driving the second compaction wheels to move in the direction away from or close to the steel wire rope; and the first rotation driving device is arranged on the mounting base, is connected with the first compaction wheels, and is used for driving the first compactionwheels to rotate. Through adoption of the rescue device for electrically lifting the elevator car after the elevator host and the internal contracting brake are broken, the problem of safety risk caused by manually lifting the elevator car in rescuing after host components are damaged in the prior art is solved, and the rescue efficiency is improved.
