Overturn type cage door for construction elevator

Abstract

The invention relates to the field of transportation operation, and aims at solving the technical problems of the traditional construction lifter used for buildings that space is reserved on the downgoing door of a cage body in the downward direction, a cage door must is matched with a special transportation bearer platform, potential safety hazards exist in the operation, damages are easy to happen, and the like. The turn type cage door of the construction lifter comprises an upgoing door 1 and a cage door heel post 17, wherein, a down turnover door 2 is arranged under the upgoing door 1, thelower edge thereof is articulated with the lower edge of the cage door, while the upper edge side face thereof is fixedly connected with a locking board 21 which is provided with a lock catch 6, a gate lock 3 of the down turnover door is arranged at the lower part of the cage door heel post 17, the height thereof far away from the lower edge of the cage door is slightly higher than that of the lock catch 6 far away from the lower edge of the cage door, and one end of a guy rope 4 is fixedly connected with the locking board 21, while the other end thereof is fixedly connected with an upgoing door tie rod 5 which is fixedly arranged at the lower edge of the upgoing door 1 by a pulley A15 arranged in the middle of the side face of the cage door and a pulley B16 arranged on the top of the cage door. The turn type cage door of the construction lifter is applicable to construction lifters.

Description

technical field [0001] The invention relates to the field of operation transportation, in particular to a construction elevator. Background technique [0002] The cage door of the construction elevator used in traditional buildings usually adopts an up and down door structure, that is, when the upper and lower cage doors are opened, they run to the top and bottom of the cargo cage respectively until they are fully opened. This type of construction elevator cage door has the following disadvantages: [0003] 1. In order to ensure the opening of the descending door, a certain space must be reserved in the downward direction of the descending door of the cage body to facilitate the opening of the descending door, which will bring great inconvenience to some constructions that cannot reserve space in advance. [0004] 2. Due to the height difference between the cage door and the operating platform after the down door is opened, a special transport platform must be built to conne...
