The invention provides a sliding door of a discharging platform for a building hoisting frame. The sliding door comprises a door frame, wherein a fixed plate is arranged on the upper part of the door frame, a door body capable of moving up and down relative to the door frame is arranged on the lower part of the door frame; at least one group of triangular grooves is symmetrically formed in the two sides of the door body; a group of triangular positioning blocks which can be inserted into the triangular grooves are symmetrically arranged on the door frame, and the triangular positioning blocks are driven by an air cylinder. According to the sliding door disclosed by the invention, the triangular grooves are formed in the door body, and one group of triangular positioning blocks which can be inserted into the triangular grooves are formed on the door frame, so that after the door body is moved to the corresponding position, the triangular positioning blocks are inserted into the triangular grooves to realize positioning and self-locking, the levelness of the door body can be automatically corrected through the triangular positioning blocks to ensure that the lower side edge of the door body is horizontal, and the door hoisting height is regulated by three groups of photoelectric induction switches and three groups of triangular grooves.
