Speed governor of elevator

Abstract

The present invention relates to a speed governor of an elevator. In particular, in the speed governor of the elevator, a rope pulley (2) is supported by a frame (10) in a rotating manner in a certain height position in an elevating path, a brake mechanism is configured to brake a speed governor rope coiled on the rope pulley (2), the rope pulley (2) is provided with a pendulum mechanism bearing centrifugal force to rotate, a fastening mechanism is arranged between the pendulum mechanism and the brake mechanism, when a rotating quantity of the pendulum mechanism is over than a prescribed quantity, the fastening mechanism make the brake mechanism to transfer from a non-working state to a working state, and a remote operation device (11) is connected to the fastening mechanism.

Description

technical field [0001] The present invention relates to a speed governor for emergency stopping of a car in an elevator when the speed of the car exceeds a specified threshold, and more particularly to a speed governor installed in a hoistway in an elevator without a machine room. Background technique [0002] For a long time, in the elevator without machine room, such as Figure 16 As shown, the driving device (100) is arranged on the upper part of the lifting road (107), the main rope (102) is wound on the sheave (101) constituting the driving device (100), and the car (103) It is connected with one end of the main rope (102), and the balance weight (104) is connected with the other end of the main rope (102). [0003] In the hoisting path (107), guide rails (105) for guiding the car (103) to go up and down are arranged. At the bottom of the car (103), an emergency stop device (90) is installed to make the car (103) stop urgently by braking the guide rail (105). [0004]...

AI Technical Summary

Problems solved by technology

[0013] However, in the existing elevator in which the inspection opening (111) is provided on the wall (110), not only the wall (110) needs to be constructed, but also the inspection opening (111) is located at a lower position than the boarding door. (108) In the high place above, the governor (9) is located deeper than the inspection opening (111), so there is a problem that the operability of the inspection operation is poor

[0014] There is no opening (111) for inspection, although the operator can also climb to the ceiling of the car (103) and approach the governor (9), but there are problems of safety and working space.

[0015] In addition, in the existing elevator in which the return lever is installed on the governor, although the governor can be restored by remote operation of the return lever, the speed of the car exceeds the specified threshold value (1.4 times the rated speed). ) and the rotation angle posture of the sheave when the sheave is stopped, that is, the position of the tenon mechanism, after the return lever is operated, it is necessary to rotate the sheave by a maximum of about 360 degrees in order to press the tenon mechanism by the return lever , when the car stops near the boarding point on the uppermost floor, sometimes there is no margin for rotating the sheave at the necessary angle, so in such a case, the speed governor cannot be restored by the restoration lever. question
