Description

Technical Field

[0001] The utility model relates to the field of elevator components, and particularly to a column profile in a hoistway. Background Art

[0002] At present, the hoistway structure of a sightseeing gantry elevator has four columns at the four corners. There are crossbars arranged on the columns, and the guide rails are installed on the hoistway crossbars through guide rail brackets. Among them, the guide rail brackets are generally made of aluminum profiles, and the guide rails and the aluminum profiles are fixed by screws.

[0003] However, the longer the aluminum profile crossbar is, the larger its span is, and the ability to bear bending stress is relatively weakened. In addition, screws are installed on the aluminum profile, and there is a stress concentration phenomenon at the connection, which weakens the bearing capacity of the aluminum profile and affects the stability of the guide rail installation structure.

[0004] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.
