Abstract

PROBLEM TO BE SOLVED: To provide a small-sized elevator control device securing both the easiness in its assembling and maintenance works and a high density mounting of a unit consisting of control components, compared with a conventional arrangement in which the assembling and maintenance works must be executed through door provided in the front and rear surfaces or solely in the front surface to result in a restricted manner of mounting component parts, etc., and a less small-sized construction. SOLUTION: A working table to be mounted removably on the elevator control device is provided separately from the device casing, and a unit consisting of control components is structured as movable easily to the working table using slide components, and thereby it is made practicable that the assembling and maintenance works are executed on the working table over a wide area from the front face and from the left and right sides.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an elevator control device.

[0002]

2. Description of the Related Art In general, in an elevator control device, since the door is located only at the front and back of the elevator control device or at the front of the elevator control device, assembly work and maintenance work are performed from these doors. For components that are relatively light in weight, a hinge panel is used to mount a swing panel with multiple control components mounted on the housing of the elevator control device, or a component that slides on the housing of the elevator control device. A method is employed in which a rail or the like is attached and a unit composed of control parts is drawn out to perform work. In addition, a control component having a large weight or a unit including the control component that cannot be used in the above method is directly mounted on a housing of the control device.

[0003]

In the above-mentioned prior art, the structure must be such that assembly and maintenance work can be performed from doors provided on the front and back of the elevator control device or only on the front. Because of the limitations, there is a limit to performing high-density mounting of components and the like while ensuring assembly workability and maintenance workability, which hinders miniaturization of the entire elevator control device.

SUMMARY OF THE INVENTION An object of the present invention is to downsize an elevator control device which ensures both assembly and maintenance workability of the elevator control device and high-density mounting of a unit including control components.

[0005]

The above object is achieved by providing a detachable work table for the elevator control device separately from the housing of the elevator control device. At the time of assembly, this work table is installed, and on this work table, a unit consisting of control components is assembled. When the relevant part is completed, the work table is moved to the elevator control device by rollers and guide rails to control the elevator. Store in device. In addition, this work table is installed during maintenance work, and the unit including the relevant control components in the elevator control device is completely pulled out onto the work table by rollers and guide rails. Store in the elevator control device from the workbench.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of a schematic configuration of an elevator control apparatus according to an embodiment of the present invention when a work table 7 is used. FIG. 2 is a front view of the unit 2 pulled out and fixed on the work table 7. FIG. 3 is a plan view corresponding to FIG.

In the figure, reference numeral 1 denotes an elevator control unit housing, 2 denotes a unit on which a plurality of control parts are mounted, 5 denotes a roller attached to the unit 2, and the unit 2 uses the rollers 5 to mount a base 9 in the elevator control unit. And workbench 7
You can move between. In order to prevent the unit 2 from falling when it moves, the unit guide 6, the elevator control device housing side guide 11, and the elevator control device housing side unit stopper 15 are provided at the upper part, and the work table guide rail 8 and the base guide rail at the lower part. 10 are provided. Further, when the unit 2 is moved, the unit 2 is stopped near the tip of the work table, and a work table side unit stopper 14 for preventing the unit 2 from falling down is provided. The unit 3 and the unit 4 are in a state fixed to the housing 1 of the elevator control device.

When assembling the unit 2, the work table 7 is attached to the base 9 in the housing 1 of the elevator control device,
The unit 2 is assembled on the worktable 7. The unit 2 that has been assembled is moved into the elevator control device housing 1 by the action of the rollers 5, the respective guides, and the guide rails, and is fixed. The unit 3 and the unit 4 are similarly assembled and fixed to the elevator control device housing 1.

When performing maintenance on the unit 2, the door 12 is opened and fixed, the work table 7 is mounted on the base 9 in the elevator control device housing 1, the unit 2 is released, and the roller 5 and the respective guides are removed. The unit 2 is moved onto the work table 7 by the action of the guide rail, and the unit guide 6 and the elevator control device housing side guide 11 are tightened with fixing bolts 13 to fix the upper part of the unit 2.
The maintenance work is performed by fixing the work table 7 with the work table side unit stopper 14. The units 3 and 4 also perform maintenance work in the same manner.

During normal operation, units 2, 3,
The unit 4 is moved and fixed in the elevator control device housing 1, the work table 7 is removed from the base 9, and the door 12 is closed.

[0012]

According to the present invention, the assembling work and the maintenance work of the unit including the control parts can be performed on the work table, so that the assembling work and the maintenance work can be performed in a wide range from the front, left and right directions. Therefore, it is possible to reduce restrictions on a mounting method of a unit including the control component for securing assembling work and maintenance workability,
By being able to mount control components at high density,
The entire elevator control device can be downsized.
