Embodiment 1

[0031] figure 1 It is a perspective view showing a schematic structure of a conventional elevator 1 provided with a stop detection device 20 under a car. Additionally, Figure 2 is figure 1 A front view ( FIG. 2( a )) and a side view ( FIG. 2( b )) of the docking detection device 20 are shown.

[0032] The car 10 of the elevator 1 is connected to one end of a main wire rope (not shown), and moves up and down in the hoistway along a pair of left and right car-side guide rails 11L, 11R, wherein the main wire rope is wound on the upper part of the hoistway. on the hoist (illustration omitted). In addition, a counterweight (not shown in the figure) is connected to the other end of the main wire rope, and in the gap formed between the inner wall surface of the hoistway and the left and right sides of the car 10, along a pair of guide rails for the hammer (not shown in the figure) ) is lifted up and down in the hoistway.

[0033] Additionally, if figure 1 As shown, a pair of lef...

Embodiment 2

[0041] FIG. 5 is a front view ( FIG. 5( a )) and a side view ( FIG. 5( b )) of a parking detection device 20 according to Embodiment 2 of the present invention. Additionally, with the figure 1 Since the same symbols attached to the above mean the same objects, descriptions thereof will be omitted, and differences will be described in detail below.

[0042] As shown in the figure, the docking detection device 20 of this embodiment further includes a second fireproof board 25 on the surface of the docking detection device body 21 on which the reflective photoelectric sensor 22 is arranged, and the second fireproof board 25 is bent. Instead, it has a shape that partially covers the reflective photoelectric sensor 22 except for the light-emitting member and the light-receiving member. The material of the second fireproof board 25 can be the same as that of the fireproof board 24 . Since the light-emitting member and the light-receiving member are covered, the docking detection o...

Embodiment 3

[0045] Figure 6 It is a perspective view showing a schematic structure of a conventional elevator equipped with a stop detection device on the upper part of a car. Additionally, Figure 7 is Figure 6 Top view (Fig. 7(a)) and side view (Fig. 7(b)) of the docking detection device shown. Additionally, with the figure 1 The same reference numerals in the reference numerals denote the same objects, and thus the description thereof will be omitted, and the differences from the first embodiment will be described in detail below.

[0046] Such as Figure 6 As shown in FIG. 7 , different from the first and second embodiments above, the stop detection device of this embodiment is fixed on the upper part of the car 10 , and an isolated photoelectric sensor 26 is used as the stop detection sensor.

[0047] The partition type photoelectric sensor 26 is connected to the main body 21 of the parking detection device, and has a light-emitting part for projecting light for parking detectio...

Abstract

The invention provides a stop detection device for an elevator, and stop of an elevator car can be accurately detected in fire hazard. The stop detection device is provided with a stop detection device body, a photoelectric sensor, and a fireproof plate fixed on the elevator car. The photoelectric sensor is fixed on the stop detection device body, and is provided with: a light-emitting part emitting light ray for stop detection; a light-receiving part receiving reflected light of the light ray, and detecting stop of the elevator car when the light-receiving state in the light-receiving part changes with the lifting of the elevator car. Except the region receiving stop detection by the photoelectric sensor, the fireproof plate covers the periphery of the stop detection device body and the photoelectric sensor.

Description

technical field [0001] The invention relates to a stop detection device for an elevator. Background technique [0002] Conventionally, when a fire broke out in a building, after the elevator was driven to the evacuation floor, call registration was prohibited, and residents were evacuated by other methods such as stairs. However, in recent years, with the increase in the height of buildings, for example, in the case of residents who are difficult to evacuate using stairs, such as the elderly, families with children, and the disabled, it may take time until the evacuation of the entire building is completed. question. In order to cope with such a problem, in the event of a disaster such as a fire, it is conceivable to actively use the hoistway divided by fire-resistant structures and the emergency elevator with fire-proof doors to quickly evacuate the residents to the evacuation floor. According to certain conditions such as the height of the building and the floor area, th...
