Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a hydraulic elevator, and more particularly to a control panel for a hydraulic elevator when the control device for a hydraulic elevator and a rope type elevator are shared.

[0002]

2. Description of the Related Art Conventionally, as described in Japanese Patent Application No. 6-221809, a control panel is installed above a hydraulic unit and an oil tank is arranged on the back side of the control panel.

[0003]

Generally, it is stipulated by law that the height of the machine room of a hydraulic elevator is 2 m or more. Therefore, by increasing the floor area as in the prior art, the hydraulic equipment was placed.The control panel is installed above the hydraulic unit, so the width is long and the height is kept low to accommodate the control equipment. Was there. Conventionally, the rope type elevator has been controlled by an inverter, but in recent years, the inverter control has also been adopted for a hydraulic elevator.
Compared with hydraulic elevators, the height of the machine room of rope-type elevators is 2.0-2.2m (when the rated speed is 150m / min or less), so the control panel of rope-type elevators has a vertically long structure It was fixed on the machine room floor as.
Even though it is an inverter-controlled elevator, there is a problem in that two types of control panels must be prepared as described above.

An object of the present invention is to provide a control panel for a hydraulic elevator that can share the control device for the hydraulic elevator and the rope type elevator.

[0005]

The above object is achieved by stacking a hydraulic unit, which is a hydraulic elevator machine room device, and an oil tank in two stages, and changing a control panel from a horizontal type to a vertical type.

[0006]

According to the present invention, the hydraulic unit, which is the equipment of the machine room of the hydraulic elevator, is fixed to the floor of the machine room, and the oil tank is installed on the upper part. Since the self-supporting control panel is arranged on the back side of the hydraulic unit and fixed to the machine room floor, the height of the machine room can be eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a hydraulic elevator control panel according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows the equipment layout of a hydraulic elevator machine room according to an embodiment of the present invention. FIG. 2 shows the configuration of a control panel for a hydraulic elevator according to an embodiment of the present invention. FIG. 3 shows an equipment arrangement of a rope type elevator machine room according to an embodiment of the present invention. FIG. 4 is a block diagram of a control device for a hydraulic elevator according to an embodiment of the present invention.

First, the structure of one embodiment of the present invention will be described with reference to FIG. 1A is a plan view, FIG. 1B is a front view, and FIG. 1C is a right side view.

In FIG. 1 (c), the hydraulic unit U is placed on the gantry G of the hydraulic unit and fixed to the floor UK of the machine room by the anchor bolts AB. Next, the oil tank T is placed on the hydraulic unit U and fixed by the connecting bracket BR. When the inspection surface of the hydraulic unit U is on the side opposite to the control panel, the pool box P is arranged on the rear side of the hydraulic unit U and is fixed to the floor UK of the machine room by the anchor bolts AB. The control panel CP is placed and fixed on the pool box P. Further, the upper part is fixed to the oil tank T by the connecting bracket BR. As can be clearly seen from FIG. 1 (a), the inspection surface of the control panel is only on the left door LD and right door RD sides. In the center, a partition plate S that divides the left and right
Is provided. Noise countermeasures are taken into consideration by mounting an inverter controller X on the right side of the control panel and a signal controller Y on the left side of FIG. 1B. A knock hole NA is provided in the lower portion of the right rear surface to secure a wire passage with the motor M shown in FIG. Further, in FIG. 1A, the space on the left side of the control panel CP is the control panel C as described later.
Since the back side of P is completely closed, it is used when adding a control device according to additional specifications. In the case of the rope type, as shown in FIG. 3, a machine MC composed of a control panel CP, a motor on the machine beam MCB, a speed reducer, etc.
The above-mentioned knock holes are not necessary since they are separated from each other (generally, the floor of the machine room is piped or ducted). Since the height of the rope type machine room is at least 2.0 m, the height of the control panel is generally 1.5 m or less.

Next, the configuration of an embodiment of the present invention will be described with reference to FIG. The control panel is an integrated structure of a ceiling, a rear panel TH, a bottom panel SD, a left side panel LS, a right side panel RS, and a partition panel S.
Assemble and fix to form a box structure. Left door L on the front side
D and the right door RD are attached so that the double door can be opened. As described above, the left and right side surfaces and the back surface side are completely closed.

Next, the operation of the embodiment of the present invention will be described with reference to FIG. In FIG. 4, a three-phase AC 200V that is a power source for driving an elevator feeds a converter COV that converts AC into DC via a fuse-free breaker F. The power source converted into DC by the converter COV is AC by an inverter INV. And is supplied to the motor M.
The motor M drives the pump P to supply the hydraulic oil in the oil tank T to the hydraulic jack J via the valve V to raise the car CAGE.

The power source three-phase AC200V is also supplied to the step-down transformer TR to control the signal control device Y such as the valve control circuit. The inverter control device X and the signal control device Y are respectively mounted in FIG. The noise resistance is improved by mounting the inverter device Y for controlling the motor and the signal control device X for controlling the solenoid valve of the valve on the left and right sides of the partition plate S as a boundary. or,
Since the output line of the inverter device Y is a wire to the motor M in the hydraulic unit, a knock hole is formed in the lower right rear part of FIG. 1B for convenience of wiring.

[0014]

According to the present invention, since the control panel of the hydraulic elevator can be shared with the rope type elevator control panel, it is modularized and standardized in all steps of design, manufacturing, inspection, installation work and maintenance inspection. You can

Further, since the control panel is subjected to maintenance and inspection only from the front side, it is advantageous in maintenance and inspection.

Further, since a knock hole is provided in the lower rear portion on the right side of the control panel, in the case of a hydraulic elevator, it is easy to connect wires to the motor.
