The guide rail lubricating apparatus according to the present invention is provided with a jump-up preventing means for preventing the lubricating oil from jumping upward from the guide rail play insertion recess formed in the main body case, so that the upper surface of the main body case is lubricated. Since the outflow of oil can be prevented to prevent contamination, if the main body case is made of a translucent material, the amount of oil can be easily visually checked from the outside.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 is a partial cross-sectional side view showing a guide rail refueling apparatus according to an embodiment of the present invention, and shows a state where the apparatus is mounted on an elevator.

A mounting member 24 is fixed to the upper part of the car 20. A guide shoe slidably fitted on a guide surface 23a of a guide rail 23 is held in a holding frame 21 fixed to the mounting member 24. ing. One end of an L-shaped bracket 22 is connected to the holding frame 21 by a bolt 33a, and the other end of the bracket 22 is connected by a bolt 33b to a guide rail oil supply device A including the main body case 10 and the cover plate 14. A plurality of oil retaining sheet members 1 (to be described in detail later) are stacked and arranged in the main body case 10 of the guide rail oil supply device A, and lubricating oil is applied to the guide surface 23a of the guide rail 23 via the oil retaining sheet members 1. Supplying.

FIG. 5 is a perspective view showing a state in which the guide rail oil supply device A is detached.

The main body case 10 is constructed by attaching a lid 14 to a bottomed box-like body 11 having a notch 11a at a portion corresponding to the guide surface 23a of the guide rail 23 via a hinge so as to be openable and closable. ing. A plurality of oil retaining sheet members 1 housed and arranged in the box-shaped body 11 of the main body case 10
Is made of a Kapok fiber into a sheet having a thickness of about 6 mm, the outer shape is formed into a shape just to fit in the box-shaped body 11, and the movement in the main body case 10 is restricted. As shown in FIG. After stacking a total of eight sheets of three types, one oil retaining sheet member 1a, the second oil retaining sheet member 1b, and the third oil retaining sheet member 1c, they are bound by a binding body 32 made of vinyl or the like and handled as a unit. I have to. As will be described later, the first oil retaining sheet member 1a and the third oil retaining sheet member 1c have a lubricating portion 5c that comes into contact with the guide surface 23a of the guide rail 23 to supply oil. 1b holds the interval between the refueling units 5c,
Used as an oil retaining member.

Each oil retaining sheet member 1 is formed with four position regulating through holes 7a to 7d formed at positions surrounding the notch 11a of the box-shaped body 11, and the lowermost first through holes 7a to 7d. The first oil retaining sheet member 1a and the second oil retaining sheet member 1b other than the three oil retaining sheet members 1c have a series of oil supply holes 2 formed therein.

Are formed, and each of the rods 12a to 12d is inserted into each of the position regulating through holes 7a to 7d of the oil retaining sheet member 1 described above. The rods 12a to 12c are arranged symmetrically with respect to the axis of the guide rail at each vertex of the triangle. However, since the rod 12d is added and the whole is asymmetric, the third oil retention is erroneously performed. The oil retaining sheet member 1 is not arranged upside down so that the sheet member 1c is located at the uppermost position. This can be achieved by arranging the rods 12a to 12d asymmetrically with respect to the axis of the guide rail regardless of the number of rods 12a to 12d.

After the oil retaining sheet member 1 shown in FIG. 5 is stored in the box-like body 11 of the main body case 10 as described above, the lid 1

FIG. 1 is a perspective view showing the main body case 10 with the cover 14 closed.

When the lid 14 is closed, the notch 11a of the box-like body 11 and the notch 14a of the lid 14 coincide with each other, so that the guide rail loose insertion recess 10a of the main body case 10 is formed.
Is formed. The mounting positional relationship between the guide rail play insertion recess 10a and the guide rail 23 is defined, and the guide surface 23a of the guide rail 23 will be described in detail later.
In order to perform good refueling, the sign bodies 8a to 8c are provided on the upper surface of the lid 14.

On the other hand, on the peripheral edge of the notch 14a of the cover 14, a jump-up preventing means 9 protruding above the upper surface of the cover 14 is provided. This jump-up prevention means 9
The cover 14 may be formed integrally with plastic resin, or may be formed separately from the cover 14, and then fixed with an adhesive or attached by fitting. The flip-up preventing means 9 in this embodiment corresponds to the oil supply section 5c of the oil retaining sheet member 1 which is in contact with the guide surface 23a of the guide rail 23 and refuels, and is located on the side of the notch 14a. It comprises a side member 9d provided in the portion, a back member 9a located on the back side of the notch 14a, and a front member 9b located on both sides on the front side of the notch 14a.

The peripheral portion of the notch 11a of the box-shaped body 11 where the guide portion 23a of the guide rail 23 is located, that is, the guide portion 2 of the guide rail 23 described later.
3a, the main body case 10
The reinforcing members 19a are arranged in the height direction of each to increase the rigidity of the portions.

FIG. 2 is a plan view showing the guide rail lubricating device A shown in FIG. 4, and shows the relationship between the guide rail loose insertion recess 10a of the main body case 10 and the guide rail 23. In the figure, the guide rail play insertion concave portion 10a
The width is represented by the notch 14a of the lid 14 as a representative, and has a width W2 that maintains a predetermined gap with respect to the thickness T2 of the guide portion 23a of the guide rail 23. Here, the width W2 of the guide rail play insertion concave portion 10a is set between the oil supply portion 5c of the oil retaining sheet member 1 and the guide portion 2 of the guide rail 23.
It is set so that lubricating oil can be satisfactorily supplied to 3a.

That is, as shown in FIG. 6 which is a front view of the same portion, the first oil retaining sheet member 1a having an oil supplying portion 5c of the oil retaining sheet member 1 which comes into direct contact with the guide portion 23a to supply oil. The third oil retaining sheet member 1c is disposed discretely in the stacking direction by interposing the second oil retaining sheet member 1b therebetween, and the oil supply portion 5c is connected to the guide portion 23.
a so as to have a sufficient contact area. Accordingly, when the car 20 descends and the guide rail refueling device A descends, the leading ends of the refueling portions 5c of the first lubricating sheet member 1a and the third lubricating sheet member 1c move upward as shown in FIG. However, the oil is effectively brought into contact with the guide portion 23a.

In order to effectively supply oil in connection with the movement of the car 20 in this manner, the width W2 of the guide rail play insertion concave portion 10a is adjusted so as to allow the oil supply portion 5c to move up and down to some extent.
And the thickness T2 of the guide portion 23a must be determined. If the gap between the two is insufficient, the refueling portion 5c formed by winding and fixing the reinforcing fiber member around the kapok fiber comes into contact with the peripheral edge of the guide rail play insertion concave portion 10a of the main body case 10, Since this contact is repeated by the vertical movement of the car 20, the car 20 is damaged early. Therefore, as shown in FIG. 2, the guide rail play insertion concave portion 10a has a width W2 that maintains a predetermined gap with respect to the thickness T2 of the guide portion 23a of the guide rail 23.

Next, refueling by the above-described guide rail refueling device A will be described.

As shown in FIG. 5, a unitized oil retaining sheet member 1 is housed in a main body case 10. At this time,
The oil retaining sheet member 1 is stored in the main body case 10 while the rod-shaped members 12a to 12d are inserted into the position regulating through holes 7a to 7c of the oil retaining sheet member 1. Thereafter or at a predetermined time, a predetermined amount of lubricating oil is injected from the oil supply units 28a to 28c, and the lid 14 is closed as shown in FIG. The guide rail refueling device A is shown in FIG.
Is attached to the car 20 as shown in FIG. At this time, as shown in FIG.
The center line of a corresponds to the display unit 8a, and the tip of the guide unit 23a corresponds to the display units 8b and 8c.

Thereafter, when the car 20 shown in FIG. 4 is moved up and down, the oil supply portions 5c of the first oil retaining sheet member 1a and the third oil retaining sheet member 1c are deformed following the vertical movement. For example, when the car 20 descends, FIG.
As described above, the lubricating portion 5c is deformed upward and the lubrication is performed on the guide surface 23a of the guide rail 23 while maintaining a good contact-like body.

The oil retaining sheet member 1 has excellent oil retaining properties,
When the moving speed of the car 20 is increased, the car 2
At the time of the drop of 0, the surplus lubricating oil is jumped upward from the contact portion between the oil supply portion 5c and the guide portion 23a. However, since the notch portion 14a of the lid 14 forming the guide rail play insertion concave portion 10a is provided with the jump-up preventing means 9, the lubricating oil jumped over the jump-up preventing means 9 passes over the lid. It does not adhere to the surface of the body 14 and becomes dirty. The height of the flip-up preventing means 9 is determined as appropriate. Therefore, even if the main body case 10 is made of a translucent material that can be seen through, there is no contamination by the lubricating oil, so that the amount of the lubricating oil and the like can be easily visually checked from the outside, and The lubricating oil supply work becomes easy.

Moreover, since the flip-up preventing means 9 is provided on the lid 14, it can be formed integrally with the lid 14, so that the relative positional relationship with respect to the lid 14 does not shift and is always maintained. Good effect can be expected. The splash-up preventing means 9 does not necessarily need to be formed integrally with the lid 14, but is provided, for example, by providing a sheet-like member in the main body case 10 so as to be located at the top of the oil retaining sheet member 1. You may. Such sheet-like flip-up prevention means 9
Is in contact with the lubrication section 5c, but since it has flexibility, it does not damage the lubrication section 5c. Therefore, by arranging the lubrication section 5c close to the guide section 23a, the lubricating oil jumps up from the notch section 14a. Can be effectively prevented.

The splashing of the lubricating oil is caused by the lubrication unit 5
Since it is generated from the contact portion between the guide portion 23a and the guide portion 23a, the side member 9c may be provided at least on both sides corresponding to the oil supply portion 5c in the cutout portion 14a of the lid 14 shown in FIG. As shown in FIG. 1, since the back member 9a and the front member 9b are formed integrally with the jump-up preventing means 9, they are also configured as a strength member. This advantage will be described below.

In order to prevent the lubricating oil from jumping upward from the guide rail play insertion concave portion 10a of the main body case 10,
As shown in FIG. 2, the width W2 of the notch 14a of the lid 14 is
However, if the width W2 of the cutout portion 14a of the cover 14 is reduced as shown in FIG. 7, the cutout portion 14a of the cover 14 comes into contact with the displacement of the oil supply portion 5c. Warpage occurs at the peripheral edge of the. Also, as shown in FIG. 8, warpage also occurs at the peripheral edge of the notch 11 a of the box-shaped body 11. Therefore, when the lubricating oil is subsequently supplied, the lid 14 is not completely closed, and the oil retaining sheet member 1 is not closed.
Cannot be completely held, and the guide rail 2
The contact between the third guide surface 23a and the oil supply portion 5c of the oil retaining sheet member 1 is deteriorated, and the oil supply to the contact portion is adversely affected.

However, as described above, the reinforcing member 19a is provided at the periphery of the guide rail play insertion recess 10a, that is, the periphery of the notch 11a of the box-shaped body 11, and the notch 14a of the lid 14 is provided. A jump-up prevention means 9 is provided on the peripheral edge, and the jump-up prevention means 9 is provided with a back member 9a, a front member 9
Since the b and the side member 9c are integrated strength members, the above-described warpage can be prevented. Therefore, the guide rail refueling device A can be manufactured as follows.

The guide rail for the elevator is an 8 km rail having a thickness of the guide portion 23a of 10 mm.
13kg rail with thickness of 16mm, guide part 23a

A guide rail lubricating apparatus A having a main body case 10 designed for each guide rail can be manufactured, but among these guide rails, attention is paid to a guide rail of an arbitrary size, and the guide rail of any size is adapted. The main body case 10 is manufactured so as to be also used as the main body case 10 having at least one size higher than an arbitrary size.

For example, as shown in FIG.
Paying attention to the guide rail 23 called the kilorail,
The thickness T2 is 10 mm, and the main body case 10 having the width W2 is manufactured as the guide rail play insertion concave portion 10a. In such a main body case 10, as described in the above-described embodiment, since the notch portion 14 a of the lid 14 forming the guide rail play insertion concave portion 10 a is provided with the flip-up preventing means 9, The splashed lubricating oil does not climb over the splash prevention means 9 and adhere to the surface of the lid 14 to be soiled. The main body case 10 is also used as a guide rail having a size at least one level higher than the 8 kilo rail, here a guide rail 23 called a normal maximum size of 30 kilo rail. The thickness T2 of the guide portion 23a is 19 mm, and the thickness T2 of the previous one is 10 mm.
mm, a deformation force is applied to the peripheral edge of the guide rail play insertion recess 10a via the oil supply portion 5c, but the peripheral edge of the guide rail play insertion recess 10a, that is, the box-shaped body 11 A reinforcing member 1 is provided at the peripheral edge of the notch 11a.
9a, and at the peripheral edge of the notch 14a of the lid 14, a flip-up preventing means 9 is provided.
Since the back member 9a, the front member 9b, and the side member 9c are formed as an integral strength member, an inexpensive guide rail refueling device can be provided by sharing parts while preventing the above-described warpage.

As described above, the main body case 10 manufactured for the 8-kilogram rail is at least one size higher than that, so the same main-body case 10 is used for two types of the 8-kilogram rail and the 13-kilogram rail. May also be used. In any case, it is desirable that the oil retaining sheet member 1 housed in the main body case 10 be prepared for each guide rail and manufactured so as to contact the guide surface 23a with Yoshihiro.
