Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator control device, and particularly to the structure of a control panel installed in a machine room.

[Conventional Technique 6#r] The control panel that inputs signals from the elevator landing and car call buttons to control the elevator drive electric motor, car position indicator, etc. Although it is installed in the machine room that houses the hoisting machine, recent advances in conductor technology have led to miniaturization, and as a result, a method has been proposed in which the control panel is installed above the hoisting machine.

The control panel installed above the hoisting machine like this.

A manual operation device used when operating an elevator at low speed, a call registration device for registering calls in the machine room and operating normally, and various indicators to check and adjust the operation of the elevator,
Equipped with regulators, etc. Therefore, the elevator has a hem,
During maintenance inspections, elevator operations are checked and adjusted efficiently by checking the operating status of the car using the display on the M control panel and operating the manual operation device and call registration device (Mitsubishi Technical Report). ,Vol,EtO,NO,I,P,f
15).

[Problem that the invention seeks to solve]

As mentioned above, since the control panel is installed above the electric motor, it is adjacent to the A car, and when operating it, there is a risk that the operator will get caught between the sheave and the rope. Attaching a protective cover to the sheave to prevent this danger not only increases costs, but also requires the removal of the protective cover during maintenance and inspection of the sheave, complicating the work. .

This invention was made to solve the above-mentioned problems, and proposes an elevator control device that can efficiently and safely check and adjust elevator operation.

[Means for solving problems]

The elevator control 'A' according to the present invention is arranged so that the display for confirming the operation of the elevator and the operating section required during the operation can be confirmed and operated from the opposite sheave side. It is arranged on the side of the car.

[Effect]

According to this invention, while the elevator is in operation, the sheave can be operated at a remote position while checking the movement of the elevator.

〔Example〕

The present invention will be explained below with reference to the embodiments shown in FIGS. 1(a), (b) and 2. FIG. 1(a) is a side view showing the mounting state of the hoisting machine and the control panel. As is clear from Figure 0, which is a plan view, the hoisting machine (1)
is installed in the machine room (3) via the stand (2). ), this mesh wheel (6)
The hook raises and lowers a car (not shown) via a turned main rope (7). An electromagnetic brake (8) is interposed between the electric motor (4) and the speed reducer (5) to brake the electric motor (4).

Further, above the electric motor (4) there is a control panel (9) with supporting legs (
! 0) so that the operation of the elevator can be confirmed and operated. This control panel (9) has an operation surface (11) shown in FIG. 2 on the side surface (8a) opposite to the mesh wheel (6). Furthermore, this operation surface (11)
is usually protected by a cover.

However, this operation surface (11) includes a circuit breaker (lla) that makes an emergency stop of the elevator and turns off the lights, and a push button (llb) that allows you to register a call, take charge of the elevator, and operate it to floor a. , a first light emitting diode (llc) for displaying the call registration floor, and a second light emitting diode (lid) for displaying the elevator car position. The car is equipped with a switch (lie) that can be switched between the operation mode and the manual operation mode, and by switching to the manual operation mode, the car is moved at low speed by the elevator command. Furthermore, by adjusting the variable resistor and rotary switch (LLF), the ride comfort of the elevator, the landing state, etc. can be adjusted. The third light emitting diode (Ilg) placed above this rotary switch (ttr) confirms the operation status of various signals for elevator control to confirm elevator operation, and if there is any abnormality, this light emitting diode (11g) The cause can be investigated by

Furthermore, there is a terminal block (IIF) below the rotary switch (LLF).
lh) are attached, and by connecting a measuring device to these, voltage, resistance, various signals, etc. at each location can be measured and confirmed. In addition, by connecting the desired device to the connector (lli) installed next to the terminal block (llh), you can read various signals or rewrite control programs and data to check the elevator operation or change the operation. It is designed so that you can do things like this.

As explained above, the connectors and terminals for connecting the parts that perform various operations and checks during elevator operation, or the devices for performing various operations and checks, are located on the control panel (9) as shown in Figure 2. Since it is placed on the side (8a) of the hoisting machine (1) that does not face the sheave (8), the sheave (6)
) The various operations and checks described above can be performed safely and efficiently while observing the operation of the sheave (8) of the hoisting machine (1) and the electromagnetic brake (8) without installing a protective cover on the hoisting machine (1). can.

In addition, although we have explained the case where parts that need to be operated and checked during elevator operation are placed on the negative side (9a) of the control panel (9), it is possible to
Similar effects can be expected even if W'l is placed on the sides (9a) and (9b).

Further, although FIG. 2 shows an example of the parts that need to be operated and checked during operation of the elevator, if there are other necessary operating parts, they may be arranged in addition to these.

It goes without saying that if there is sufficient space on the side where the parts that need to be operated and checked while the elevator is in operation are arranged, other equipment may also be arranged.

In the above FIGS. 1(a) and 1(b), the case where the control panel (9) is installed above the electric motor (4) has been described.

It may be installed on other parts of the hoisting machine (1) or above the entire hoisting machine (1), or even if it is installed next to the hoisting machine (1) in the lateral direction, it can be operated and checked while the elevator is operating. It goes without saying that the same effect can be obtained by installing the part on the side that does not face the mesh wheel (6).

〔Effect of the invention〕

As described above, according to the present invention, the part of the control panel placed above the hoisting machine that needs to be operated during elevator operation is placed in the opposite position from the sheave, making it possible to efficiently check and adjust the operation during elevator operation. It can be done well and safely.
