Description

Rope head beam device of elevator without machine room

Technical Field

The utility model belongs to the technical field of elevators, and particularly relates to a rope hitch beam device of an elevator without a machine room.

Background

In an elevator without a machine room hoistway structure, two main fixing modes are adopted for the rope head beam of an elevator car, one is to fix the rope head beam on a guide rail in a cantilever mode, and the other is to fix one end of the rope head beam on the guide rail, and the other end of the rope head beam is connected with a hoistway wall through a bottom plate to achieve fixation. Both fixing modes have the advantages that the guide rail needs to bear the bending force of the rope head beam, so that the strength of the guide rail needs to be improved, the outsourced guide rail standard part needs to be subjected to secondary reinforcement design or a guide rail with higher specification is selected, the input cost is obviously increased, and the enterprise competitiveness is reduced.
