Abstract
The present invention provides an elevator device which is installed with a speed detecting unit in a speed adjustor at a condition that a hoist trunk is not widened. The elevator device according to the invention comprises the following components: an elevator cage (8) which lifts in the host trunk (100); an annular speed adjustor rope (11) which is connected with emergency braking devices (13, 14) installed on the elevator cage (8) and moves along with the lifting of elevator cage (8); a tension pulley (12) which exerts tension to the speed adjustor rope (11); and a speed adjustor (9) which seizes the speed adjustor cable (11) for activating the emergency braking devices (13, 14) when the elevator cage (8) exceeds a preset speed. In the elevator device according to the invention, the tension pulley (12) is installed below the contact position in which the elevator cage (8) contacts a buffer (20) installed in the elevator pit (40). Furthermore the elevator according to the invention is provided with a detecting unit which is axially installed with the tension pulley (12) and is used for detecting the position or speed of elevator cage (8).
Description
Technical field
The present invention especially relates to a kind of lift facility with detecting unit of the position of detecting lift car or speed.
Background technology
In the lift facility of prior art, a kind of lift facility is for example disclosed in patent documentation 1, the roller that this lift facility has by contacting with the governor pulley detects the position of lift car or the detecting unit (for example with reference to patent documentation 1) of speed, a kind of lift facility is perhaps for example disclosed in patent documentation 2, this lift facility have with the setting of governor pulley coaxle be used to detect the position of lift car or the detecting unit of speed (for example with reference to patent documentation 2).
The flat 6-144734 communique of patent documentation 1 Japan's open patent
In recent years, there is not the volume of the so-called machine room-less elevator of Machine Room constantly to increase.The characteristics of the maximum of these machine room-less elevators are at the Outside Dimensions of lift car, to suppress the size of hoist trunk as much as possible, to realize the hoist trunk of miniaturization.And, in machine room-less elevator, generally governor is configured in the hoist trunk and the position of staggering through path lift car.
For this reason, when as above-mentioned prior art, in governor, speed detection unit being set, may cause hoist trunk to narrow down, make the gap between the equipment in gap between the lift car to guarantee hoist trunk and lifting therein fully or hoist trunk and other the hoist trunk, at this moment, have to widen hoist trunk.
Summary of the invention
The object of the present invention is to provide a kind of lift facility that speed detection unit can be set in governor under the situation of not widening hoist trunk.
To achieve these goals, the invention provides a kind of lift facility, this lift facility has: the lift car of lifting in hoist trunk; The governor rope of emergency braking apparatus connection on being installed in this lift car and the ring-type that moves along with the lifting of described lift car; Apply the tension roller of tension force to this governor rope; And when described lift car surpasses specified speed, catch the governor rope and make the governor of emergency braking apparatus action, it is characterized in that, described tension roller is arranged on described lift car and the below that is arranged on the contacted contact position of energy disperser in the elevator hole, and have with the coaxial setting of described tension roller be used to detect the position of described lift car or the detecting unit of speed.
As implied above, owing to tension roller is arranged on lift car and is arranged on the below of the contact position that the energy disperser of elevator in cheating contact, and have with the coaxial setting of tension roller be used to detect the position of lift car or the detecting unit of speed, so can not disturb, thereby can solve problems such as to widen hoist trunk with other equipment in the hoist trunk.
The invention effect
Because tension roller is arranged on lift car and the below that is arranged on the contacted contact position of energy disperser in the elevator hole, and have with the coaxial setting of this tension roller be used to detect the position of lift car or the detecting unit of speed, so can not disturb, thereby can solve problems such as to widen hoist trunk with other equipment in the hoist trunk.

The specific embodiment
With reference to the accompanying drawings embodiments of the present invention are described.
Fig. 1 is the integral structure figure of expression as the lift facility of object of the present invention, and Fig. 2 is the hoist trunk longitudinal sectional drawing that the position of governor and the lift car of presentation graphs 1 concerns.
As shown in the figure, in lift facility, main hoist cable 2 is wound on the driving rope sheave 1 of winch, by pulley 3～7, connects lift car 8 and counterbalanced weight 8 ' in two ends of main hoist cable 2, to form the bucket type elevator.And,, the main hoist cable 2 that is wound on the described driving rope sheave is moved, thereby makes lift car 8 carry out lifting along guide rail (not shown) by making described driving rope sheave 1 rotation.20 expression energy dispersers, 9 expression governors.Be wound with the governor rope 11 of ring-type on the pulley 10 of this governor 9, be provided with tension roller 12 in the lower end of this governor rope 11, this tension roller 12 is arranged in the below of the contact position that described lift car 8 contacts with the energy disperser 20 that is arranged on elevator hole 40.
The part of described lift car 8 and described governor rope 11 is connected by the rod member (not shown) that is used for pull-up emergency braking apparatus 13,14, when normal operation, with the speed of described lift car 8 pulley 10 of described governor 9 is rotated driving, and in that to detect lift car former in thereby when having surpassed the speed of regulation certain, make the rod member action by described governor rope 11, thereby make emergency braking apparatus 13,14 actions, lift car 8 is promptly stopped.
On described tension roller 12 coaxial, has rotary encoder 15 as the detecting unit of the position of detecting lift car or speed.
As shown in Figure 2, in hoist trunk 100, because lift car 8 can not drop to the position that disposes tension roller 12, therefore, even on tension roller 12 coaxial, be provided for detecting the position of lift car or the rotary encoder 15 of speed, also not can and other equipment between produce and disturb.
And,, therefore can also be useful on the forced reduction apparatus of terminal floor owing to can detect the position and the speed of lift car by rotary encoder 15 with tension roller 12 coaxial settings.
In addition, the situation that is arranged on hoist trunk top 30 with described governor 9 is that example is described in the present embodiment, but the position that is provided with of governor 9 is not limited in this, and for example, governor 9 also can be configured in the elevator hole 40.
