Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevator guide rails, in particular to a shock-absorbing elevator guide rail which is easy to install. Background Art
[0002] Elevator guide rails are elevator components made of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. They are divided into three types according to the cross-sectional shape: T-shaped, L-shaped and hollow. While playing a guiding role, the guide rails bear the impact force of the car and elevator during braking, the impact force of the safety clamp during emergency braking, etc. The magnitude of these forces is related to the load and speed of the elevator, so the guide rails should be selected according to the elevator speed and load. Usually, the car guide rail is called the main rail, and the counterweight guide rail is called the auxiliary rail.
[0003] The elevator guide rail provides guidance for the car and counterweight device when the elevator is running, and also plays a supporting role when the safety clamp is braked. It is an important component in the elevator system.
[0004] Usually, the guide rails are processed in sections, and the accessories of the guide rails are processed into specified lengths. The guide rail components are spliced into long straight rail structures at the installation site. The length of the straight rail structure is formed by connecting different numbers of segmented guide rails. The length of the connection is determined by the length of the elevator's running stroke. The elevator guide rails are fixed in the elevator shaft through a connecting structure. Since the elevator guide rails are connected structures, the gaps in the connections will change according to seasonal temperature changes, causing abnormal noises in the elevator guide rails, affecting the comfort of the elevator ride. In addition, when the guide rail device is generally installed, there is no shock absorbing mechanism at the bottom, which can easily cause wear of the guide rails during long-term use, shortening the service life of the guide rails. Therefore, improvements are needed. Utility Model Content
