Problems solved by technology

Therefore, it is more difficult to adjust the action position of the detection switch 4 for the ascending displacement and descending displacement of the speed regulating tensioner 1 respectively.
[0009] On the other hand, the existing speed governor cable abnormality detection device described in Patent Document 2 detects the abnormality of the governor cable through a distance sensor and a microcomputer. , there is a problem that the overall cost of the detection device is relatively high

Embodiment Construction

[0037] Below, refer to Figure 1 to Figure 6 An example of the present invention will be described.

[0038] here, figure 1 To illustrate a perspective view of an embodiment of the present invention, figure 2 It is a front view of the speed governor cable state detection device when the speed governor tensioner is raised from the normal position. also, image 3 To show the front view of the governor cable state detection device when the governor tensioner is lowered from the normal position, Figure 4 It is a front view showing the governor wire rope state detection device in the case of abnormal vibration on the governor tensioner. also Figure 5 is a schematic explanatory diagram showing the detection position of the detection switch, Image 6 It is a perspective view showing the whole elevator device.

[0039] First, through Image 6 The overall structure of the elevator will be described.

[0040] like Image 6As shown, the elevator device 10 has an elevator ro...

Abstract

Disclosed is a speed regulator wire rope state detection device of a lift and a lift control system which detect the wire rope state of a lift speed regulator through detecting the up-down movement of a speed regulating tensioner. The speed regulator wire rope state detection device (50) of a lift comprises a bracket (62) for mounting a detection switch, one end of which is fixed on one side of alift guide rail (14R), the detection switch (54) mounted on the other end of the bracket (62) and the speed regulating tensioner (51) which is provided with a tensioner pulley (53) coiling with a speed regulator wire rope (29) and a tensioner counterweight (55), moreover, a on-off action plate (58) is moved up and down integratively with the speed regulating tensioner (51) and arranged near the detection switch (54), under the condition that the speed regulating tensioner (51) is moved up or down more than a special distance, the on-off action plates (58), (59) drive the detection switch (54)to detect the state of the speed regulator wire rope (29).

Description

technical field [0001] The invention relates to an elevator governor steel cable state detection device which detects abnormal states of the governor steel cable such as hooking, cutting off, falling off of the pulley, etc. The control system of the elevator with the speed switch steel cable state detection device. Background technique [0002] Conventionally, as a device for detecting an abnormality in a governor cable of an elevator, a governor cable abnormality detection device for an elevator described in Patent Document 1 and a governor cable for an elevator described in Patent Document 2 are known. Anomaly detection device. [0003] Figure 7 It is a diagram showing a conventional elevator governor cable abnormality detection device described in Patent Document 1. exist Figure 7 Among them, the elevator speed governor steel cable abnormal detection device has: a detection arm 3, the detection arm 3 is installed on the anti-vibration support 2 of the speed control...
