Description

[Detailed Description of the Invention] This invention relates to an electric lifting device for lifting and lowering a high ceiling lighting fixture.

Conventionally, this type of electric lifting device has a motor 4 attached to a main body 1 fixed to a ceiling surface 6, as shown in the overall configuration in FIG.
The wire rope 5 is moved up and down by reverse rotation, and the lamp 1 attached to the lifting part 2 at the tip of the wire rope 5 can be raised and lowered from the floor surface 7 to the insertion part 12 of the main body 1. . Note that 9 is an operation box, 8 and 13 are operation wiring and lamp wiring (hereinafter both are collectively referred to as external wiring) wired between the operation box 9 and the main body 3, and 11 is a mounting bracket.

However, in the case of an electric lifting device having such a configuration, a terminal board 14 is provided on the surface of the main body 3 facing the ceiling surface 6 when the main body 3 is installed, and a cylindrical shape surrounding the main body 3 is provided. A cover A15 was fitted onto the ceiling surface 6 side of the cover B21 and secured with screws, and the external wirings 8 and 13 were inserted through the cover A15. To connect the external wiring 8, 13 and the terminal board 14, as shown in FIG. This was done after removing the cover A15 from the cover B21. Therefore, since the connection work has to be done at a high place, the mounting screw 19
The above configuration with a large number of parts has the drawback that installation is extremely difficult, and parts such as the mounting screw 19 and cover A15 fall during work, resulting in wasteful work such as collecting these parts and supplying new parts due to powder loss. It was hot. The cover B21 also includes an insertion portion 12 formed in the main body 3.
Since it covers from the outside, the elevating section 2 and the insertion section 1
If there is a problem with cover A1,
5 had to be removed, which had the disadvantage of requiring time and effort in maintenance and inspection.

This idea was made in view of the above-mentioned drawbacks, and the cover surrounding the main body is provided so that it can be opened and closed, and when the cover is open, the terminal board and the insertion section are arranged so that they can be exposed from the open side of the cover. ,
The purpose of the present invention is to provide an electric lifting device that is easy to install and easy to maintain and inspect.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4.

3 is a main body formed of a rectangular flat metal plate, each side of which is bent into an L-shape. 26 is a disc-shaped bottom plate fixed to the lower end of this main body 3;
Reference numeral 22 is a disk-shaped top plate fixed to the upper end of the main body 3 and having the same diameter as the bottom plate 26, forming two external wiring insertion holes 16. 4 is a motor attached to one plane part of the main body 3, 24 and 25 are thin metal plates bent and formed into a cylindrical shape with both ends open, and are divided into two, and semi-cylindrical covers C and 25 are respectively formed. A cover D25 is shown, and the cover D25 is fixed to the main body 3 so as to cover the surface of the main body 3 on the side where the motor 4 is attached. The cover C24 has one end attached to the cover D25 via a hinge 23 so as to be openable and closable, and when in the closed state, is integrated with the cover D25 and works together with the cover D25 to completely cover the main body 3. surround. Reference numeral 14 denotes a terminal board attached to the flat surface opposite to the motor mounting surface of the main body 3, and 12 denotes an insertion part attached to the bottom plate 26 into which the lifting part 2, which will be described later, is removably inserted. 12 and the terminal board 14 are covered by the cover C24.
When in the open state, it is exposed to the cover C24 side. 5 is a wire rope wound around a rotating shaft (not shown) that is directly connected to the motor 4; 2 is a lifting section suspended from the tip of the wire rope 5;
The contact point 30 provided on the upper surface fits into the insertion portion 12 when raised, and the lamp 1 is attached to the lower surface. This lifting section 2 is raised and lowered as the wire rope 5 moves up and down due to the forward and reverse rotation of the motor 4. Reference numeral 11 denotes a U-shaped mounting bracket that is attached to an insert bolt 17 protruding from the ceiling surface 6 through a mounting hole 20, and the main body 3 can be moved from a horizontal position using tightening screws 10 inserted in both legs. It is supported so that its position can be adjusted arbitrarily up to the vertical position. 27 is a fixing screw for the cover C24 screwed onto the periphery of the bottom plate 26, and 8 and 13 are external wirings inserted through the external wiring insertion hole 16 and electrically connected to the terminal board 14. In addition, 25 is a spirit level, 18 is a nut,
28 is the cover fixing screw.

In the electric lifting device of the above embodiment, the external electric wires 8, 13 can be connected to the terminal board 14 by loosening the fixing screws 27 and opening the cover C24. In reality, there are many mounting screws 19 (often 4 or more) on the main body 3.
The workability is much better than that of removing the cover A15 more completely, then separating the cover A15 from the cover B21, and supporting the cover A15 with the external electric wires 8 and 13 inserted therein. ing. Furthermore, there is no fear of the mounting screws 19 being lost or the cover A15 falling during work. Further, since the insertion section 12 is exposed by opening the cover C24, the insertion state of the insertion section 12 and the elevating section 2 can be easily determined, and maintenance and inspection work can be simplified.

In the above embodiment, the cover D25 is fixed to the main body 3, but the present invention is not limited to this, and it may be provided so that it can be opened and closed like the cover C24, and in this case, maintenance of the motor 4, etc. , it is clear that inspection becomes easier.

As explained above, this invention divides the cover that covers the main body, provides the cover so that it can be opened, and arranges the terminal board and insertion section attached to the main body so that they can be exposed from the opened side of the cover. This makes installation easier and maintenance and inspection easier, and its practical value is great.
