Abstract

Provided is a rope swing preventing device for an elevator governor capable of saving space and energy. The speed governor rope swing prevention device for an elevator is continuously or intermittently extended and arranged between the speed governor (4) and the tensioning pulley (7), shields the governor rope (5) in three directions, and The main body (8a, 8b) of the preventer with an opening on the side of the lifting lever and the belt (12) moving synchronously with the elevator car (3) for closing the opening of the main body (8a, 8b) of the preventer, wherein , one end of the belt (12) is connected to the elevator car (3) above the lifting rod, and the other end of the belt (12) is connected to the elevator car (3) below the lifting rod, The belt return wheel (10) is arranged on the top of the lifting passage (1), and the belt tensioning wheel (11) is set at the bottom of the lifting passage (1), and the belt (12) is arranged in a ring shape.

Description

technical field [0001] The invention relates to a speed governor rope swing prevention device for an elevator used for preventing the speed governor rope from swinging. Background technique [0002] In general, in an elevator, a speed governor is provided to make an emergency stop of the lifting body, that is, the elevator car, when an abnormality occurs, and the speed governor has a speed governor that circulates in synchronization with the elevator car. rope. Moreover, the very long speed governor rope will shake during an earthquake and may interfere with the equipment in the lifting passage, causing damage to such equipment. Therefore, in order to prevent the above situation from happening, a speed governor rope is provided. preventive device (for example, refer to Patent Document 1). [0003] Refer to the following image 3 and Figure 4 A conventional rope swing preventing device for a governor for an elevator will be described. [0004] image 3 It is a schematic ...
