Description

Technical Field

[0001] The utility model mainly relates to the technical field of elevator accessories, and in particular to an elevator brake friction plate. Background Art

[0002] The friction pad of the elevator brake is a friction material used to generate resistance through friction contact with the brake disc when the elevator needs to stop or slow down, thereby achieving a smooth stop of the elevator. The design and material selection of the brake pad must ensure that stable friction performance and durability can be maintained during long-term use.

[0003] The friction plate of the elevator brake is a wearing part. Long-term friction will reduce the roughness of its surface, which will affect the braking effect of the elevator. Therefore, it needs to be replaced in time. However, only the friction part of the friction plate is worn, while the rest is intact. The overall replacement cost is high. Utility Model Content

[0006] 2. Technical solution:

[0007] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: an elevator brake friction plate, including a main body, the main body is annular, and movable grooves of predetermined depth are opened at both ends, a disc spring coaxially distributed therewith is arranged in the movable groove, a movable disk is fixedly installed at the end of the disc spring, and a friction component is detachably installed on the outer surface of the movable disk.

[0008] Furthermore, the inner surface of the movable disk is fixedly mounted with circumferentially arranged guide slide posts, and the guide slide posts are slidably connected to guide slide sleeves arranged in the movable groove.

[0009] Furthermore, the friction assembly includes a mounting ring, and the outer surface of the mounting ring is provided with a first friction protrusion and a second friction protrusion arranged circumferentially, wherein the thickness of the first friction protrusion is greater than that of the second friction protrusion.

[0010] Furthermore, the mounting ring and the movable disk are connected via circumferentially arranged positioning bolts.

[0011] Furthermore, an insert ring is fixedly mounted on the inner surface of the mounting ring, and the insert ring is inserted into a slot provided on the outer surface of the movable disk.

[0012] 3. Beneficial effects:

[0013] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: the disc spring can enable the friction component to provide a predetermined pressure when in contact with the brake wheel, thereby ensuring that the friction force meets the braking requirements, and the friction component is detachable and installable. When the friction component is severely worn, it only needs to be replaced, saving costs;

[0014] The first friction protrusion is thicker than the second friction protrusion. When rubbing against the brake wheel, after the first friction protrusion is worn, the second friction protrusion can continue to rub against the brake wheel, thereby achieving the purpose of increasing the service life.
