Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a solid lubricant application device, and more particularly to a novel improvement for simplifying the configuration by holding a solid lubricant between a holding member provided directly on each rotary arm and a tip surface of the rotary arm.
[0002]
[Prior art]
Conventionally, as this type of solid lubricant application device used, a notch-shaped step portion is formed in a holding portion formed at the tip of a pair of rotating arms, and a leaf spring provided on the holding portion is provided. The base portion of the solid lubricant is sandwiched between the tongue piece at the tip and the stepped portion.
[0003]
[Problems to be solved by the invention]
Since the conventional solid lubricant application device is configured as described above, the following problems exist.
That is, since the solid lubricant is sandwiched between the step portion of the holding portion formed at the tip portion of the rotating arm and the tip portion of the leaf spring provided in the holding portion, the formation cost of the holding portion and the step portion is reduced. As a result, the structure was complicated.
[0004]
The present invention has been made to solve the above-described problems, and in particular, the solid lubricant is sandwiched between the holding member directly provided on each rotating arm and the tip surface of the rotating arm, thereby simplifying the configuration. An object of the present invention is to provide a solid lubricant coating apparatus.
[0005]
[Means for Solving the Problems]
A solid lubricant application device according to the present invention is provided in the traveling body in a solid lubricant coating apparatus that is attached to a traveling body that travels on a rail and that applies a solid lubricant to a flange portion of a wheel of the traveling body. A pair of rotating arms urged to rotate in different directions via spring members on both sides of the holding plate, and a U-shaped cross section that is operatively fitted in the respective rotating arms. A holding member in the form of a longitudinal groove, a tongue piece formed by bending at the tip of each holding member, a U-shaped locking portion formed on the back of each holding member, and each holding member. A notch located at the back of each pivot arm, a lever positioned at a part of each notch and fixed to the back of the arm by a plurality of bolts, and a shaft support for each lever (53) Lever provided in a freely rotatable manner And a rectangular frame-shaped connecting body provided between the engaging portion and the locking portion of each lever, and each connecting body operates with respect to the engaging portion and the locking portion. The holding members are reciprocally moved along the longitudinal direction of the rotary arms via the coupling body by the rotation of the levers, and between the distal end surfaces of the rotary arms and the tongue pieces. The interval for clamping or releasing the base of the solid lubricant is changed, and the surface direction of the tip surface is the front of the arm facing the back of the arm from the back of the arm where the lever body of each of the rotating arms is located. It is the structure formed so that it may become a downward inclination toward a part and may become non-orthogonal with respect to the said longitudinal direction.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of a solid lubricant coating device according to the present invention will be described with reference to the drawings.
1 is a known traveling body, and a wheel 2 provided at a lower portion of the traveling body 1 is configured to travel on a known rail (not shown). The solid lubricant 5 is applied to the flange portion 4.
[0007]
A pair of rotating arms 8 and 9 are urged in one direction by spring members 10 such as torsion springs on opposite sides of the holding plate 6 provided at the lower part of the traveling body 1 via shaft support portions 7 in different directions. It is configured to be.
[0008]
Wherein the respective rotary arm 8,9, as shown in FIG 2 and 3 and 5, the pivot arm in a state of fitting the longitudinal groove-shaped holding members 11 and 12 by the cross-sectional face shape The holding members 11 and 12 are provided with U-shaped locking portions 40 on the back portions 11a and 12a side. Moreover, the notch part 41 and the bending part 42 are formed in this back part 11a, 12a.
[0009]
A tip end surface 21 is formed at the tip end of each of the pivot arms 8 and 9, which is formed only of a plane and whose surface direction is not orthogonal to the longitudinal direction 20 of each of the pivot arms 8 and 9.
A tongue piece 22 formed by bending is provided at the tip of each holding member 11, 12, and the base portion of each solid lubricant 5 is sandwiched between the tip surface 21 and the tongue piece 22. Being held.
[0010]
The notches 41 of the holding members 11 and 12 are positioned on the arm back portions 8a and 9a of the rotary arms 8 and 9, and a part of the notches 41 is positioned in the notches 41 and the lever 50 is provided. The lever body 51 is fixed by a bolt 52.
The lever 50 can be rotated in the direction of the arrow A on the shaft support 53 of the lever body 51, and a rectangular frame-like connecting body is provided between the engaging portion 54 of the lever 50 and the locking portion 40. 60 is provided.
[0011]
The connecting body 60 is operably coupled to the engaging portion 54 and the locking portion 40, and the holding members 11, 12 are moved through the connecting body 60 by the rotation of the lever 50. The distance between the distal end surface 21 and the tongue piece 22 can be changed.
That is, the lever 50 is rotated upward in the state of FIG. 2, the holding members 11, 12 of the rotating arms 8, 9 are lifted, and the tongue piece 22 serves as the base of the solid lubricant 5. When the lever 50 is rotated downward from the state shown in FIG. 2, the tongue piece 22 is lowered together with the turning arms 11 and 12 via the connecting body 60, and the distal end surface 21 and the tongue piece are brought together. The holding of the solid lubricant 5 is released with an interval between the two.
As shown in FIG. 2 and the like, the surface direction of the distal end surface 21 is an arm facing the arm back 8a, 9a from the arm back 8a, 9a where the lever body 51 of each rotary arm 8, 9 is located. It forms so that it may become a downward slope toward the front parts 8b and 9b.
[0012]
【The invention's effect】
Since the solid lubricant applicator according to the present invention is configured as described above, the following effects can be obtained.
That is, the holding member provided in each rotating arm can be reciprocated by the rotation of the lever, and the solid lubricant can be sandwiched and released. Cost reduction can be achieved.
