Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an engager position detection device for detecting the proper position of an engagement piece of a hatch door with respect to an engagement device of an elevator car door.

[Background of the idea]

Generally, in an elevator having a structure in which a cage door and a hatch door engage with each other, an engagement piece attached to the hatch door and an engagement device attached to the cage door must be properly attached at relative engagement positions.

Since a general elevator has one cage door for each hatch door attached to each floor, the engagement piece of the hatch door is attached based on the engagement device of the cage door. However, if the arrangement of these engaging elements is misaligned, the engaging piece of the hatch door and the engaging device of the cage door will not properly engage with each other while the elevator is running, and there is a risk that the engaging element will be damaged. In order to prevent such problems, it is necessary to accurately attach the engagement piece of the hatch door and the engagement device of the cage door at predetermined mutual positions. Furthermore, as the position of the engaging portion changes due to wear of the car guide and door mechanism over time, it is necessary to periodically inspect the positions of both.

In conventional inspections, workers visually inspect the car from above the car, which not only makes it impossible to accurately determine the placement of the engaging pieces, but also allows workers to ride on the car at low speeds and inspect the engaging pieces on each floor. The work was dangerous, as it required inspecting the layout of the equipment, and inspections took a great deal of time.

To solve these problems, a device described in Japanese Utility Model Application Publication No. 58-134362 has been proposed, but the inspection method using this device requires workers to stop the elevator at each floor and to open the doors. Since the elevators operated on each floor without stopping, the elevators had the disadvantage that general users were unable to use the elevators during inspections.

[Purpose of invention]

An object of the present invention is to provide an engaging element position detection device that can detect whether an engaging piece is in a proper position during normal operation of an elevator.

[Summary of the idea]

The features of the present invention include a non-contact detection device that is attached to a position facing the above-mentioned engagement piece of the cage door and outputs a signal by detecting whether or not the above-mentioned engagement piece is facing each other; a determining means for determining whether the relative positional relationship is good or bad based on the output state of a signal from the inspection detection device when the condition that the car is closed and the condition that the car is in a predetermined position are satisfied; The present invention is provided with means for reading and storing the floor when determined, and means for displaying the floor stored in the storage means.

With the above configuration, the relative engagement positional relationship between the engagement piece and the engagement device can be automatically measured during normal automatic operation of the elevator, and the defective floor can then be known by the display means. Therefore, it is possible to improve the efficiency of maintenance work, and to suppress the downtime rate of conventional elevators due to this work.

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a plan view showing a part of the engager position detection device according to an embodiment of the present invention, in which one
A pair of hatch doors 1 that can be opened and closed are constructed.
Furthermore, a pair of openable and closable cage doors 2 formed on the car 5 are opposed to the hatch door 1. An engaging element is formed in the facing portions of both doors 1 and 2. The engaging piece consists of an engaging piece 3 attached to the hatch door 1 and an engaging device 4 attached to the cage door 2. When the car 5 stops at a predetermined floor, the engaging device 4 is moved by a drive device (not shown). The lever is operated to clamp the engaging piece 3, and in this state both doors 1 and 2 are opened simultaneously.

Figure 3 shows an enlarged view of the main parts of Figure 2.
Detection is made at a position facing the engagement piece 3 when the car 5 has landed on an arbitrary floor and both doors 1 and 2 are still closed, that is, at an intermediate position between the pair of rollers constituting the engagement device 4. A device 7, for example a proximity sensor, is arranged and this detection device 7 is attached to the cage door 2. This non-contact type proximity sensor generates an output signal when the engaging pieces 3 reach the opposing positions, as shown in, for example, Japanese Utility Model Application No. 58-134362.

Next, the specific configuration of the engaging element position detection device will be explained using FIG. 1.

When the car 2 stops at a predetermined floor, the detection device 7 provided on the car door 2 at a position facing the engagement piece 3 generates an output signal only when the engagement piece 3 is at the opposing position. The output signal of the detection device 7 is input to the determiner 8, and the determiner 8 inputs the signal from the detection device 7 in synchronization with the signal from the detection zone signal generator 9. The detection zone signal generator 9 is
When the condition that the cage door 2 is closed and the condition of the arrangement zone in which the engagement piece 3 and the engagement device 4 are in the positional relationship where they should be engaged by the elevator car position detection device etc. are satisfied at the same time, the determination device 8 give a signal. The determiner 8 that receives this signal inputs the signal from the detection device 7, and if this input signal is present, it determines that the position of the engaging piece 3 is normal, whereas if this input signal is not present, the position of the engaging piece 3 is determined to be normal. Since the position No. 3 is inappropriate, an output signal is given to the storage device 10. The storage device 10 that receives this signal inputs and stores the current floor from the floor signal generator 11 and outputs it to the display and recording device 12. Display and recording device 1
2 displays the inappropriate position of the engagement piece 3 and the corresponding floor on the display panel and records it with a printer.

In this example, the display and recording device 12 was activated when the position of the engagement piece 3 was inappropriate.
It is also possible to display and record the engagement piece 3 in the normal position.

According to the engager position detection device having such a configuration, the signal from the detection device 7 is received when both the condition that the door is closed and the condition that the car has reached a predetermined position are satisfied, and the signal is detected when the car is engaged. Since the position of the piece 3 is detected, it can be detected without having to stop the car at each floor, and work efficiency can be improved.

[Effect of idea]

As explained above, in the present invention, when both the condition that the door is closed and the condition that the car reaches a predetermined position, that is, a position where the engagement piece and the engagement device can be engaged, the detection device Since it is detected whether or not the engaging piece on the hatch door side is in the normal position, the detection can be performed even when the elevator is in normal automatic operation.
