Description

Elevator upper beam

Technical Field

The application relates to the technical field of elevators, in particular to an upper beam of an elevator.

Background

The "wrap angle" is also explained in the tool book as "contact angle", also called "winding angle", and in an elevator hoisting system, it refers to the central angle corresponding to the contact arc length of a hoisting suspension rope (e.g. a steel wire rope) and a drive sheave (i.e. a traction sheave), and is an important parameter for determining the hoisting capacity of an elevator. According to GB7588-2003 annex M, an elevator should have sufficient traction capacity in normal operating operation, i.e. the rope does not slip, but when the counterweight (or car) is in the hold, it is also required that the traction machine slips and the car (or counterweight) cannot be lifted. Under the same condition, the larger the elevator traction wrap angle is, the larger the elevator traction capacity is, and vice versa.

In the prior art, when the situation that the traction capacity of the elevator is insufficient or the traction force is excessive occurs, the elevator can be adjusted only by replacing a traction wheel, adjusting the number of counter weights and the counterweight blocks, changing the structure of the elevator and the like.
