Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator control panel device, and more particularly to an elevator control panel device configured so that wiring can be directly routed from the control panel to the hoistway.

[Prior art] As a conventional elevator control panel device of this type,
For example, the technology disclosed in Japanese Patent No. 4-47764 can be mentioned.

FIG. 5 is a plan sectional view of a machine room showing the conventional elevator control panel device disclosed in the above-mentioned publication.

In the figure, (1) is the hoistway, (2) is the machine room provided at the top of the hoistway (1), (3) is the support beam fixed to the floor of the machine room (2), and (4) is the machine room provided at the top of the hoistway (1). is a hoist installed on a support beam (3) directly above the hoistway (1). (
5) is a machine room (
2) is a wiring insertion hole formed in the floor surface, and (6) is a control panel installed on the support beam (3) so as to be located above the wiring insertion hole (5).

In the conventional elevator control panel device configured as described above, the wiring from the control panel (6) to the hoistway (1) passes from the lower part of the control panel (6) through the wiring insertion opening (5) to the hoistway ( 1).

Therefore, it is possible to eliminate the wiring duct in the machine room (2) and the cinder concrete that eliminates the protrusion of the wiring duct, thereby reducing wiring costs.

[Problems to be Solved by the Invention] However, according to the conventional elevator control panel device, as described above, since the control panel (6) is installed at a high position on the support beam (3), the control panel ( During maintenance and inspection in step 6), there were cases where the support beam (3) had to be used as a foothold, which resulted in poor workability. Moreover, since the center of gravity of the control panel (6) becomes higher, earthquake-proofing measures such as improving the strength are required, leading to an increase in the cost of the control panel (6). Furthermore, there was also a concern that the vibrations of the hoist (4) during operation would be transmitted to the control panel (6) via the support beam (3) and adversely affect the internal equipment of the control panel (6).

In addition, the working space around the control panel (6) in the machine room (2) is normally specified to be 50 cm or more ("Explanation of technical standards for elevators and escalators" published by the Japan Elevator Association in 1984). (Page 78, No. 1). However, according to the conventional elevator control panel device, since the control panel (6) is installed on the support beam (3),
The position and orientation of the control panel (6) is naturally limited in relation to the hoisting machine (4), and may vary depending on the deviation of the machine room (2) with respect to the hoistway (1) or the size of the machine room (2). In some cases, it was not possible to secure the above-mentioned specified working space around the control panel (6). Moreover, since the support beam (3) becomes longer by the length of the control panel (6), the degree of freedom in layout of various equipment in the machine room (2) is also reduced.

Therefore, an object of the present invention is to provide an elevator control panel device that can install the control panel in a location with good workability, secure a specified work space around it, and improve the freedom of layout of the entire machine room. It is about providing.

[Means for Solving the Problems] In order to solve the above problems, in the elevator system of the present invention, a hoisting machine is installed in a machine room located at the top of the hoistway, and the hoisting machine is installed in a machine room located at the top of the hoistway. A wiring insertion hole is formed on the floor of the machine room at the location where the wires pass from the machine room to the hoistway, and a control panel is installed on the floor of the machine room including the wiring insertion hole, and An inspection cover is provided on the side of the control panel.

[Function] In the elevator control panel device of the present invention, a wiring insertion hole is formed on the floor of the machine room at a position corresponding to a corner of the hoistway, and the wiring is routed from the lower part of the control panel to the hoistway through the wire insertion hole. wired directly to the

Therefore, the control panel can be installed low on a flat surface and its maintenance and inspection work can be performed safely and easily. Moreover, since the center of gravity of the control panel is lowered, special earthquake-resistant structures are no longer required, and manufacturing costs can be reduced. Furthermore, since the vibration of the hoist during operation is less likely to be transmitted to the control panel, there is no need to worry about adverse effects on the internal equipment of the control panel. In addition, since the control panel is installed on the floor of the machine room that includes the wiring insertion opening, if the position and orientation of the control panel is changed within the area corresponding to the wiring insertion opening, it will be possible to place the control panel in front of the inspection cover. This not only makes it easier to secure work space for the machine room, but also improves the flexibility of the layout of the entire machine room.

The leg piece (15) is reinforced, and the surrounding plate (1
The wiring insertion port (11) is closed by the closing plate (18) of 7), thereby preventing foreign matter from falling into the hoistway (1). In addition, if cinder concrete (indicated path) is to be poured on the floor of the machine room (2) due to noise reduction measures or special circumstances, the cinder concrete box (13
) is prevented from flowing to the bottom of the box (1
3) Electrical equipment inside is protected from moisture during concrete drying.

The installation position of the control panel (12) is not limited to the example illustrated in FIG. 1, but may be on the floor of the machine room (2) that includes the wiring insertion hole (11). Therefore, for example, the location shown in FIG. As shown in (a) and (b), the control panel (12) can be moved within the area including the wiring insertion port (11) to change its installation position and orientation as desired. In this way, depending on the size of the machine room (2) and its wall position, the installation position and orientation of the hoisting machine (4), or the overall layout of the machine room (2), a specified (50 cm) working space can be created.

The machine room (2) is wired directly to the hoistway (1) through the
) and the use of cinder concrete to eliminate the protrusion of the wiring duct, it is possible to significantly reduce wiring costs. Furthermore, since the control panel (12) is installed at a low level on the smooth floor of the machine room (2) rather than on the support beam (3), maintenance and inspection work can be performed safely and easily.

Furthermore, since the center of gravity of the control panel (12) is lowered, there is no need for an earthquake-resistant structure with special strength, and the manufacturing cost can be reduced. Furthermore, the vibration of the hoisting machine (4) during operation causes the control panel (1
