Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator oil pot mounting structure provided for lubricating an elevator guide rail.

[0002]

2. Description of the Related Art In elevators, as a guide when ascending and descending,
An elevator guide rail 1 is provided in a hoistway. In this method, an elevator guide rail 1 is provided in the vicinity of an elevator car 14, and a guide shoe 10 as a means for engaging with the elevator guide rail 1 is provided on the elevator car 14 side, and is used as a guide when ascending and descending. In general, the elevator guide rail 1 has a substantially T-shaped cross section and its shaft portion is directed toward the elevator car 14, and is engaged with the guide shoe 10 so that the shaft portion is generally sandwiched. Therefore, the lubricating oil 13 is caused to flow through the elevator guide rail 1 so that the guide shoe 10 can slide without resistance when ascending and descending.

As described above, a guide rail oil pot is used to supply the lubricating oil 13 to the elevator guide rail 1. As shown in FIG. 3 and FIG. 4, a container for storing the lubricating oil 13, a supply unit 11 for supplying an appropriate amount of the lubricating oil 13 to the elevator guide rail 1, and sending the lubricating oil 13 to the supplying unit 11 And a sending unit 12. Although these are shown as one unit, the elevator oil pot 7 and the supply unit 11 may be separate bodies. As a material of the supply unit 11 and the sending unit 12, a felt or the like that sucks up the lubricating oil 13 in the elevator oil pot 7 by a capillary effect is used.
In the figure, both are provided integrally.

[0004] The mounting structure of the elevator oil pot 7 is provided above the elevator guide rail 1.
There is a method of transmitting the lubricating oil 3 as the elevator 3 moves up and down while the elevator guide rail 1 is provided on the elevator car side. However, in the former case, since the lubricating oil 13 is naturally transmitted from the upper part of the elevator guide rail 1 and it is difficult to uniformly apply the lubricating oil 13 to the sliding portion of the guide shoe 10, the latter method is generally used. Many are used.

FIG. 8 shows the latter type, and shows a mounting structure of an oil pot 7 for an elevator. The dotted line in the figure is the elevator guide rail 1. FIG. 7 is an enlarged perspective view of only the essential parts. According to this, the elevator guide rail 1 installed in the elevator hoistway and used at the time of elevator elevating, and the vertical member 3 facing the elevator guide rail 1 are connected to the elevator car 1
4 is provided upwardly from a platform table 5 on which the platform 4 is placed, and a guide shoe 10 is provided between the elevator guide rail 1 and the vertical member 3 on the side surface of the vertical member 3 (not shown in FIG. 7). The elevator oil pot 7 for mounting the elevator oil pot 7 for supplying the lubricating oil 13 to the rail 1 is mounted on the vertical member 3.

Accordingly, it is possible to supply the lubricating oil 13 to the vicinity of the guide shoe 10 as the elevator moves up and down.

Further, in the figure, two vertical members 3 are provided on both sides of the rear portion of the platform base 5, and a horizontal member 4 is provided therebetween to form the vertical frame 2. Thereby, two elevator guide rails 1 can be arranged, and the elevator can be raised and lowered reliably.

Here, the length of the vertical member 3 is determined by the stroke length of the hydraulic jack 18 used for lifting and lowering, and the length of the vertical member 3 is determined according to this length. This stroke length cannot be shortened because it is determined by the length that the elevator car 14 can land on the lowest floor. Normally, when the elevator car 14 is placed on the platform 5, the upper end of the vertical member 3 rises above the elevator car. .

[0009]

However, in the conventional mounting structure of the oil pot 7 for an elevator, since the oil pot 7 for the elevator is mounted on the upper end of the vertical member 3, the oil pot 7 for the elevator usually pops out on the elevator car 14. Will be.

On the other hand, according to the Building Standards Law, elevator cars 14
It is required that the gap L between the shaft and the upper surface of the hoistway be 5 cm or more. However, since the vertical members 3 and the elevator oil pot 7 are provided, a gap of 5 cm or more is actually required. There is a problem that extra space is generated by taking a gap more than necessary, which leads to an increase in construction costs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to mount an elevator oil pot capable of minimizing a gap between an elevator car and a hoistway upper surface. Is to provide the structure.
