Description

Technical Field

[0001] The utility model relates to the field of car top wheel components, in particular to a car top wheel component for a shallow pit machine roomless passenger elevator. Background Art

[0002] Elevator is a general term for vertical transportation tools and fixed lifting equipment in buildings. Different types of elevators are set up according to the height and purpose of the building. At present, with the development of the times, elevators have become an indispensable part of many floor buildings. Most of the existing rope pulley arrangements are directly rigidly connected to the upper main beam on the top of the car, or use rubber bodies for simple shock absorption. In this way, the entire elevator equipment will vibrate and make noise, and other parts may collide with each other and fall, thereby affecting the safety of the entire elevator. At the same time, most of the existing rope pulley assemblies are not stable enough when fixing the rope pulley, and most of them are prone to wear during use because there are no shock-absorbing measures. At the same time, the wire wheel is also easily damaged due to frequent use and needs to be replaced in time. Therefore, it is urgent to set up a wear-resistant rope pulley assembly that can be used for a long time and is very stable, and has good shock absorption and noise reduction effects.
