Embodiment Construction

[0082] In order to make the objects and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with examples. It should be understood that the following words are only used to describe one or several specific implementation modes of the present invention, and do not strictly limit the protection scope of the specific claims of the present invention.

[0083] Such as Figure 1-45 As shown, the speed-limiting fall arrester with high protection level applied to the elevator includes an installation shell 100 installed on the moving object and connected with the guide rail. 200. The braking device 300 connected to the triggering device 200 for braking the moving object. The triggering device 200 is set to switch between the triggered state and the non-triggered state. The triggering device 200 is used to sense the direction of the moving object along the guide rail. and make the trigger device 200 rotate. When the mo...

Abstract

The invention discloses a high-protection-level speed-limiting falling protector applied to an elevator. The falling protector comprises an installation shell installed on a movement object and connected with a guide rail. A triggering device located on one side of the guide rail and abutting against the guide rail and a braking device connected with the triggering device and used for braking themovement object are installed on the installation shell. The triggering device is switched between a triggered state and a non-triggered state and is used for sensing the movement of the movement object along the guide rail in the guiding direction and making the triggering device do rotation movements. A driving device is arranged on the installation shell. A guide groove matched with the guide rail is formed in the installation shell. The triggering device comprises a triggering rotation shaft and a speed sensing mechanism. The triggering rotation shaft is movably connected to the driving device and can rotate around the axis. The central axis of the triggering rotation shaft is perpendicular to the installation shell.

Description

technical field [0001] The invention relates to a fall arrester, in particular to a speed-limiting fall arrester applied to elevators with a high protection level. Background technique [0002] The anti-fall device is also called the speed difference device, which can quickly brake and lock the falling object within a limited distance. The anti-fall device is mainly used in the safety protection of elevators and elevators to avoid damage to personnel and equipment caused by the rapid decline of elevators and elevators. [0003] At the moment of elevator braking, due to the huge inertia of the entire elevator equipment, a huge impact force can be generated during braking. The existing anti-dropping device adopts friction braking, but the braking effect of the existing anti-falling device using friction braking Poor, needs further improvement. Contents of the invention [0004] In order to solve the deficiencies of the prior art, the object of the present invention is to pr...
