Elevator hoist and elevator device

Abstract

An elevator hoist, wherein mechanisms for adjusting a gap between linings formed so as to come into contact with and separate from a brake drum and the brake drum when the linings are separated from the brake drum are installed in an arms for supporting the linings, whereby the adjustment of the gap between the linings and the brake drum can be performed easily in a short time.

Description

technical field [0001] The invention relates to an elevator hoist and elevator device that drives a traction rope to lift a car and a counterweight, in particular to an elevator hoist and an elevator device with a braking part near a brake drum. Background technique [0002] In the conventional elevator hoist, the brake part for braking the brake drum is placed in the brake drum. [0003] Below, use Image 6 A conventional elevator hoist will be described. Image 6 It is a schematic cross-sectional view of a conventional elevator hoist. [0004] In the figure, a braking part is placed inside the brake drum 1 which receives thrust and rotates around a main shaft not shown in the figure. The braking part mainly consists of a lining 2, a braking coil 3, an armature 4, and a coil fixing part. 5, arm 6, compression spring 7, spacer 12 constitute. [0005] In detail, the coil fixing part 5 is fixed at the central part of the brake drum 1 . The coil fixing part 5 is sandwiched, ...

Problems solved by technology

[0019] In addition, these adjustment operations are usually repeated alternately by the inspection of parallelism or clearance and the reassembly of the relatively heavy brake coil 3 to meet the requirements, which is a time-consuming and labor-intensive operation.

In addition, the spacer 12 is usually formed with a thickness of about 0.1mm. Not only does it need to improve the precision of the part to reduce the deviation between parts, but also it can only be adjusted by an amount proportional to its thickness.
