Problems solved by technology
[0002] At present, there are two ways to start the skylight of most construction hoists on the market. One is purely manual opening. Due to the material of the skylight, the skylight is relatively heavy. It is particularly difficult to open and close manually
The other is a semi-automatic opening method, which is combined with a hydraulic lever. It is more convenient to open and close, but it is a vulnerable part, and the later maintenance cost is high.

The invention relates to a crawling ladder linkage skylight opening and closing structure. The crawling ladder linkage skylight opening and closing structure is installed on an elevator cage and comprises a crawling ladder installed on the inner side of the cage and a cover plate installed on a cage top plate, a window is formed in the cage top plate, the window is covered with the cover plate, the crawling ladder is movably installed on the cage in the vertical direction, two guide plates are fixedly connected to the inner wall of the window, each guide plate is provided with a sectional guide groove, each sectional guide groove comprises a vertical guide groove and a rotary guide groove, the vertical guide grooves communicate with the rotary guide grooves, sliding strips are arranged in the sectional guide grooves in a sliding fit mode, the upper ends of the sliding strips are fixedly connected to the cover plate, one of the guide plates is rotatably provided with a gear through a short shaft, the upper end of the crawling ladder drives the gear to rotate through a transmission assembly, the lower end of the matching sliding strip on the guide plate is in transmission connection with the gear through a multi-section connecting rod assembly, and the two sliding strips are in transmission connection through a rotating shaft. According to the crawling ladder linkage skylight opening and closing structure and the construction hoist cage, the crawling ladder linkage skylight opening and closing structure is convenient to operate and low in maintenance cost.
Description
technical field [0001] The invention relates to the technical field of construction elevators, in particular to a ladder-linked skylight opening and closing structure and a construction elevator cage. Background technique [0002] At present, the skylights of the vast majority of construction elevators on the market are divided into two types. One is purely manual opening. Due to the material of the skylight, the skylight is relatively heavy, and it is particularly difficult to open and close only by hand. The other is a semi-automatic opening method, which is combined with a hydraulic lever, which is more convenient to open and close, but it is a vulnerable part, and the later maintenance cost is high. Contents of the invention [0003] In order to overcome the technical defects of the prior art, the present invention provides a ladder-linked skylight opening and closing structure, which is convenient in operation and low in maintenance cost. [0004] The technical solut...
