Abstract

PURPOSE:To reduce a cost for manufacture and maintenance of a door device, and improve reliability of the opening/closing operation by providing an engaging body, which is held in a back position in ordinary, in a door of a cage, and providing a control device for displacing the engaging body to a progress position when the cage is stopped at a landing stage. CONSTITUTION:When a rising cage 2 is stopped at an objective landing stage 3 by an operation command device 8, a parallel link 5b is turned clockwise by a driving mechanism 5c, which consists of a rotary actuator, to make an engaging plate 5a progress, and the engaging plate 5a is engaged with an engaging piece 6 provided in a door 3b of the landing stage. Next, a door 2f of the cage is opened by an opening/closing mechanism 4 having an electric motor 4b for driving the door 2f of the cage, and is closed after a predetermined time is passed, but, since the door 3b of the landing stage is engaged, the door 3b of the landing stage is opened/closed with the door 2f of the cage. Opening/ closing of the door 2f of the cage and the door 3b of the landing stage is performed by one engaging body 6, of which longitudinal direction is located along the vertical line, even in a block of an elevating passage 1 having a different angle of inclination.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an oblique elevator system in which a section is formed in a hoistway at an angle of inclination with respect to a horizontal plane.

[Conventional technology]

For example, Japanese Patent Laid-Open No. 58-63678 discloses the following skew elevator system. That is, a hoistway is provided in which landings are arranged in sections having different inclination angles with respect to a horizontal plane, and a car ascends and descends in this hoistway while maintaining a horizontal attitude. The car door is provided with engaging members corresponding to the respective inclination angles, and the matching member of these engaging members engages with the engaging member of the landing.

When the conventional skew elevator apparatus as described above arrives at the car or the landing, matching engaging members engage with each other and the car door and the landing are opened and closed together.

[Problem to be solved by the invention] In the conventional diagonal electric heater device as described above.

Since the car door requires a plurality of engaging members for opening and closing operations, there are problems in that the manufacturing cost increases and the number of maintenance adjustments increases. In addition, the engaging members of the car and the landing operate along the angle of inclination to engage.

When the inclination angle approaches horizontal, a large vertical component of force is generated when the door opens and closes. As a result, the related parts have become larger, the manufacturing cost has increased by one weight, and the number of locks has increased by one.

There was a problem in that it could become a hindrance to the unlocking operation.

The present invention has been made to solve such problems, and an object of the present invention is to obtain a diagonal elevator system that can open and close each of the landings in sections with different inclination angles by a single engaging body provided on the car. shall be.

[Means to solve the problem]

In the skew elevator device according to the present invention.

An engaging body is provided on the car door and is normally held in a backward position, and a control device is provided that displaces the engaging body to a forward position when the car stops at a landing.

[Effect]

When a car of a diagonal elevator system constructed as described above stops at a landing, the engaging body moves forward and engages with the engaging member of the landing. The car door and the landing door are then opened and closed together.

〔Example〕

FIGS. 1 to 5 are diagrams showing an embodiment of the present invention. In FIG.
, a) an inclined hoistway with a second section (1b), (
2) is a trolley (2a) that is raised and lowered on the rails (2) laid in the hoistway (1), and a trolley (2a) that is pivotally supported on the - side by the trolley (2a) and supported by jacks (2b) on the other side. 2c
), a car room (2e) that stands up on the car floor (2C) and is provided with an entrance/exit (2d), and a car door (2f) consisting of a central sliding door that opens and closes the entrance/exit (2d).

(3) is a landing provided in the first section (la) and the second section (1b), and is equipped with an entrance/exit (3a) and a landing door (3b) consisting of a central sliding door. (4) The rail that supported the car door (2f) with the car door device (
4a) is equipped with an opening/closing mechanism (4C) having an electric motor (4b) that drives the car door (2f). (5) is an engaging body provided on the car door (2f), the - side is pivotally attached to the car door (2 doors), and the other side is a parallel link (5b) that pivots the engagement plate (5a) , one parallel link (5b)
It is equipped with a drive mechanism (5C) consisting of a rotary actuator provided at the base. (6) is the landing door (
3b) and an engaging member having an engaging groove corresponding to the engaging member (5), (7) a car operation panel 4 landing button (both not shown), etc. It is a control device that operates.

The diagonal elevator system configured as described above is a car (2) connected to a rope (both not shown) by two machines.
The vehicle is then towed up and down the hoistway (1).

Then, the jack (2b) is energized in each of the first section (la) and the second section (1b), and the bracket (2C) is energized.
) remains horizontal. Further, when the car (2) being raised and lowered stops at the destination landing (3) by the operation command device (8).

The control device (7) performs the following operations.

That is, the drive mechanism (5C) is energized and the parallel link (
5b) rotates clockwise in FIG.
) moves forward and engages with the engaging element (6), resulting in the state shown in FIGS. 4 and 5. Next, the opening/closing mechanism [4] is energized to release the car door (2f) and close it after a predetermined time.
Since the landing door (3b) is engaged, the car door (2F
) opens and closes with the A basket door like this (2F)
The opening and closing of the landing door (3b) is achieved by one engaging body (5) whose longitudinal axis is arranged along a vertical line even in sections of the hoistway (1) with different inclination angles. Therefore, one unit of related equipment can be manufactured at low cost, and maintenance and adjustment work can also be simplified. In addition, since only a vertical component force is generated as a reaction force when the landing door (3b) opens and closes, the parts of a normal elevator that goes up and down vertically can be used as the landing door (3b) related parts, and the manufacturing cost is reduced. It is possible to easily obtain normal operation when locking and unlocking the nine doors.

In addition, in the embodiment of FIGS. 1 to 5, the movable engaging body (5) is provided on the landing door (3b), and the engaging element (6) is provided on the car door (2f). It is clear that the same effect as the embodiment shown in FIGS. 1 to 5 can be obtained.

〔Effect of the invention〕

As explained below, when going up or down a hoistway in which landings are provided in sections with different inclination angles, or stopping at a landing, the locking mechanism provided on one of the car door and the landing door is activated. When they are combined or moved forward, they engage with an engaging element provided on the other of the two parts, thereby opening and closing the two parts together. As a result, the above-mentioned engagement between the two is achieved by one engagement body whose longitudinal axis is arranged along the vertical line. This has the effect of reducing the manufacturing cost and maintenance cost of the door device of the cutter diagonal elevator device, and improving the reliability of opening and closing operations.
