The utility model discloses a rail transit point switch angle steel lifting device which comprises a sliding outer frame structure, and a bearing part for bearing point switch angle steel is formed at the bottom of the sliding outer frame structure. The jack is connected with the sliding outer frame structure and located in the sliding outer frame structure; the jack is supported at the upper end of the steel rail, the steel rail is located at the end of the angle iron in the length direction, and the ejection end of the jack extends out towards one side of the top of the sliding outer frame to drive the point switch angle iron to move upwards through the sliding outer frame structure and be tightly attached to the lower surface of the angle iron. According to the point switch angle steel lifting device, the jack drives the sliding rod of the sliding outer frame structure to move in the vertical direction, so that the point switch angle steel borne at the lower end of the sliding rod is driven to move in the
