Sliding door of discharging platform for building hoisting frame

Abstract

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.

Description

technical field [0001] The invention relates to a sliding door of a discharge platform for a building lifting frame, which belongs to the field of building technology. Background technique [0002] The lifting frame is an indispensable scaffolding in building construction, especially in decoration projects. The vertical transportation of materials is completed by the cage installed on the lifting frame, and the unloading platform is the link between the lifting frame and the building under construction. In order to eliminate potential safety hazards, the usual practice is to weld a simple flat door with steel bars as the safety protection door of the unloading platform at the construction site. The driving device of the safety protection door is a human driving device. The driving device requires workers to open (close) the protective door before (after) carrying materials, which delays time, wastes manpower, increases the construction process, and reduces work efficiency. ...
