Description

  The present invention relates to an elevator control device, and more particularly to an elevator control device that facilitates installation work and maintenance work of a control panel main body.

  Generally, in an elevator, equipment such as a control panel and a hoisting machine is provided in a machine room, and this machine room is installed on the roof of a building. When a machine room is formed on the roof of a building, the machine room part protrudes on the roof of the building, and there is a problem that the appearance of the entire building is impaired. With these backgrounds, in recent years, in order to improve the appearance of the building, save space, or reduce construction costs, a hoisting machine, a control panel, etc. are installed in the hoistway to create a machine room. The number of elevators that do not require is increasing.

In an elevator that does not require this type of machine room, various improvements have been made in connection with the installation of a control device.
For example, when the control device is installed in a hoistway, the workability of maintenance and inspection of the control device is worse than when the control device is installed in a machine room.
Therefore, in order to enhance the workability of maintenance and inspection of the control device installed in the hoistway, Patent Document 1 discloses that the power receiving panel, the resistor box, and the main control panel, which are conventionally configured integrally as a control device, are separately provided. The power receiving panel, the resistor box, and the main control panel are distributed in a horizontal direction at a maintainable height from the pit floor surface of the hoistway and are attached to the hoistway wall surface.

Further, in Patent Document 2, a power receiving panel, a control panel, and a resistor panel are arranged in an area that can be reached by a worker who performs maintenance and inspection work, and a duct panel that does not require maintenance work cannot be reached by the worker. It is described that it is arranged in a distributed manner according to the necessity of maintenance work, such as arranging in an area.

  However, as in the prior art described in Patent Documents 1 and 2, when the control device is divided from the bit floor to a position with good workability, it is waterproof to cope with the situation of flooding of the hoistway pit due to rain or the like. Countermeasures are required. In addition, it can be said that it is dangerous to perform a maintenance inspection in the hoistway pit because there is a car overhead. In addition, if the control device is divided and configured, the number of wiring connection points between devices increases, and not only does the wiring work take time, but there is also anxiety about the contact reliability of the outside line.

  Therefore, the object of the present invention is to solve the problems of the prior art, and without disposing the control device in the pit, it is possible to arrange the control device at a position where maintenance workability is good. It is an object of the present invention to provide an elevator control device that reduces the number of wiring connections between devices and reduces the burden of wiring connection laying work.

  In order to achieve the above-mentioned object, the invention of claim 1 is a control that is installed in a hoistway of an elevator without a machine room and that implements operation control, equipment that receives electric power, a capacitor, etc. mounted on a control panel. In the apparatus, the control panel is installed on the wall of the hoistway so that the lowermost surface of the casing of the control panel is positioned above the upper surface of the lowest floor car. .

  In the first aspect of the present invention, it is preferable that the control panel is composed of a control panel in which the respective devices are mounted in an integral housing.

  Further, the invention of claim 3 is a control device that is installed in an elevator hoistway without a machine room and that implements operation control, a device that receives electric power, a capacitor, and the like mounted on the control panel. The casing is divided into a plurality of independent casings having the same outer dimensions, and the control panel is arranged so that the lowermost surface of the casing is located above the upper surface of the trunk room of the car stopped on the uppermost floor. It is installed in the wall part of a hoistway.

  According to the invention of claim 3, the present invention is configured such that the control panel is a control panel in which the respective devices are mounted in an integrally structured housing.

  Further, in the first and third aspects of the invention, the casing of the control panel is configured so that external wiring can be intensively drawn from only the lowermost surface of the casing, and the external external line is included in the casing. It is preferable to provide a plurality of metal partition plates that divide the laying area for each type in the width direction or depth direction of the housing. The wiring laying area in each housing may be divided into both regions depending on one side inside the housing.

  According to the present invention, it is possible to arrange the control device at a position with good workability for maintenance and inspection without arranging the control device in the pit at the lowest part of the hoistway. This reduces the burden of wiring connection laying work.

Embodiments of an elevator control apparatus according to the present invention will be described below with reference to the accompanying drawings.
First embodiment
FIG. 1 shows a first embodiment of an elevator control apparatus according to the present invention. In FIG. 1, reference numeral 1 indicates an elevator hoistway. The hoistway 1 is partitioned by wall surfaces 2 on all sides. Reference numeral 3 indicates a car. Reference numeral 4 is a car door. This elevator is an elevator without a machine room, and reference numeral 5 is an elevator control device.

  The elevator control device 5 has a casing 6 of a control panel. The housing 6 according to this embodiment is an integrated housing. And inside the housing | casing 6, when the raising / lowering of the car 3 is controlled, the resistor 7 which consumes the regenerative electric power which generate | occur | produces with the motor of a hoisting machine, and the external power supply to the elevator control apparatus 5 are supplied. A power receiver 8 that receives power, a device that converts the received power into elevator-controlled power, a power-related device 8 that includes a capacitor that provides a backup power supply in the event of a power failure in the external power supply, and the power received from the external power supply A power device 10 that converts to motive power for raising and lowering the car 3, a control device 12 that controls the raising and lowering of the car 4, and the like are mounted. An external line 15 is connected to each of these devices.

  In FIG. 1, reference numeral 14 indicates the construction surface of the lowest floor of the hall. FIG. 1 shows a state where the car 3 is stopped at the lowest floor of the hall. The elevator control device 5 is installed on the wall surface 2 of the hoistway 1 so that the lowermost surface of the housing 6 of the control panel is located above the upper surface 3a of the car 3 in relation to the car 3. It is attached. And as for the upper limit of the arrangement height of the elevator control device 5, as shown in FIG. 1, when the worker 13 gets on the upper surface 3 a of the car 3 stopped at the lowest floor of the landing, It is located within a height range that allows various maintenance and inspection operations to be performed without hindrance.

  According to the present embodiment, first, a power-related device 8 such as a resistor 7 and a power receiver, a power device 10, a control device 12, and the like are placed in an integrated housing 6 of a control panel constituting the elevator control device 5. Because it is built in, the number of wiring connection points between each device is reduced compared to an elevator control device in which a conventional divided control panel is distributed in the hoistway, which reduces wiring work man-hours and improves contact reliability. Can be planned.

  In addition, the elevator control device is installed near the pit at the bottom of the hoistway by installing it at a position higher than the upper surface 3a of the car 3 stopped on the lowest floor in relation to the landing. Compared to the conventional elevator control device, which has been indispensable to take measures against flooding due to rain, etc., it is completely unnecessary to take measures against flooding of each device in the control panel. In addition, since each device can be integrated in a single control panel, the worker 13 gets on the car 3 as shown in FIG. 1 without moving the place for wiring connection work and maintenance work. Maintenance and inspections can be performed with good workability while maintaining a good scaffold.

  Next, FIG. 2 shows the arrangement and wiring status of each device inside the integrated casing 6 of the control panel. Reference numeral 15 a is an external line connected to a power-related device 8 such as a power receiver among the external lines, and reference number 15 b is connected to a power device 10 that converts the received power to a power source for the car 3. It is an outside line. These outer lines 15a and 15b are classified as power lines. On the other hand, the outside line 15 c is an outside line that functions as a signal line for transmitting control signals from the landing, the hoistway, and the car 3 to the control device 12. These external lines 15a, 15b, and 15c are wired in the casing 6 of the control panel so as to be drawn only from the bottom surface thereof. Inside the housing 6 of the control panel, the devices such as the resistor 7, the power supply related device 8, the power device 10, and the control device 12 are arranged in a line up and down so as to approach one side of the housing 6. The wiring laying area is secured on the other side.

  Inside the integrated cabinet 6 of the control panel, metal partition plates 18 a and 18 b are arranged in the wiring laying area 16 at intervals in the width direction of the cabinet 6. In the case of this control panel, two partition plates 18a and 18b are used to partition the area for each of the external lines 15a, 15b and 15c.

  In this manner, the wiring laying area is divided in the integrated housing 6 according to the types of the external lines 15a, 15b, and 15c. For example, when the integrated housing 6 is a thin housing to save space, the outside line laying area inside the housing tends to be narrowed and the margin tends to be lost if the outside lines are intensively drawn from the bottom surface. However, as in this embodiment, by dividing the outer lines 15a, 15b, and 15c in a limited space by partitioning them with the partition plates 18a and 18b, the control signal lines are separated from the electromagnetic induction and static electricity from the power lines. Wiring laying that is not easily affected by electrical induction is possible.

  Next, FIG. 3 shows another embodiment of the partition plate that partitions the wiring laying area inside the integrated housing 6. In the embodiment shown in FIG. 3, two partition plates 19a and 19b bent in a Z-shape are arranged at intervals in the depth direction of the housing 6, and an area is defined for each of the outer lines 15a, 15b, and 15c. is doing.

  At the time of actual wiring laying work, first, with no partition plate, the external line 15c is drawn from the lower surface of the housing 6 and connected to the control device 12 arranged at the lowest level. When the wiring laying of the outer line 15c is completed, as shown in FIG. 4, a partition plate 19b is attached, and the outer line 15b is drawn inside the partition plate 19b and connected to the power equipment 9. When the connection is completed, the next partition plate 19a is attached, the external line 15a is pulled in, and the power supply related device 8 is connected.

  In this way, by dividing the interior of the integrated housing 6 by the partition plates 19a and 19b, the outer lines 15a, 15b and 15c are neatly divided in a limited space, and the control signal lines are electromagnetically separated from the power lines. Wiring can be laid with little influence from induction or electrostatic induction.
