no. 1 approach example

[0032] 1-1. Structural example of elevator, governor device and governor tensioning mechanism

[0033] First, refer to figure 1 The structure of the elevator of 1st Embodiment (henceforth "this example") is demonstrated.

[0034] figure 1 It is a schematic configuration diagram showing a configuration example of the elevator of this example.

[0035] Such as figure 1 As shown, the elevator 1 of this example performs an ascending and descending operation in a hoistway 110 formed in a building. The elevator 1 includes an elevator car 120 on which people or goods are placed, a main rope 130 , a counterweight 140 , a hoist 100 , and a governor device 10 . In addition, the elevator 1 includes an emergency brake device 190 and a guide rail 200 . It should be noted that the elevator passage 110 is formed in a building, and a machine room 160 is provided at the top thereof. In addition, a pit 161 is provided at the bottom of the lifting passage 110 .

[0036] The elevator car 1...

Abstract

The invention provides a governor tensioning mechanism, a governor device and an elevator, which can smoothly guide a tension pulley with a simple structure and prevent a governor guide rail from being deformed. The governor tensioning mechanism (15) includes a casing (21), a governor guide rail (22), a tension weight (25), main engaging bodies (23, 24), and a sub engaging body (26). The tension weight (25) is disposed below the tension pulley (12) in the up and down direction. The main engaging bodies (23, 24) are disposed on the side where the tension pulley is disposed in the vertical direction of the casing (21). The sub engaging body (26) is disposed on the side where the tension weight is disposed in the vertical direction of the casing (21). Further, a gap between the sub engaging body (26) and the governor guide rail (22) is set to be larger than a gap between the main engaging bodies (23, 24) and the governor guide rail (22).

Description

technical field [0001] The present invention relates to a governor tensioning mechanism for applying tension to a governor rope of a governor device for monitoring the ascending and descending speed of an elevator car, a governor device and an elevator equipped with the governor tensioning mechanism. . Background technique [0002] Conventionally, an elevator includes an elevator car, a counterweight, a sling connecting the elevator car and the counterweight, and a hoist around which the sling is wound. In addition, the elevator is equipped with a governor device for constantly monitoring the ascending and descending speed of the elevator car and making an emergency stop of the elevator car reaching a speed equal to or higher than a predetermined speed. [0003] Specifically, when the speed governor device exceeds the rated speed of the elevator car and reaches the first overspeed (usually 1.3 times the rated speed), the governor device will drive the power supply of the ho...
