Conventionally, since the solid lubricant coating device that has been used is configured as described above, the following problems exist.
In other words, since only a pair of solid lubricants can be attached to the apparatus, it is impossible to apply sufficient lubricant to the wheels, and it has been an industry request to realize sufficient application.

  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. First and second rotating arms biased to rotate in different directions via spring members on both side portions of the holding body, and a cross-section provided operatively in a state of being fitted to the respective rotating arms. A U-shaped holding member in the form of a longitudinal groove, a tongue 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 A notch portion formed in a member and positioned at the back of each of the rotating arms, a lever body partially positioned within each notch and fixed to the back of the arm by a plurality of bolts, and a shaft of each lever body Provided in the branch so that it can rotate freely 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 holding or releasing the base of the solid lubricant is changed, and both directions of the front end surface are the front part of the arm facing the back of the arm from the back of the arm where the lever body of each rotating arm is located. In the solid lubricant application device having a configuration that is inclined downward toward the longitudinal direction and is non-orthogonal to the longitudinal direction, the first rotating arm is a first holding portion of the holding body. A pair is provided on both sides of the second A pair of arms are provided on both surfaces of the second holding portion of the holding body and are used by holding the four solid lubricants, and the entire shape of the holding body is bent in a step shape when viewed in plan. The first rotating arms are arranged at one end of the holding body so as to be separated from each other via a support shaft, and the second rotating arms are arranged at the other end of the holding body via a support shaft. The first and second rotating arms are arranged so as to be spaced apart from each other, and the first and second rotating arms are arranged in a staggered pattern in the order of the second, first, second and first rotating arms. And the holding body includes a central support member provided on the traveling body, and the first and second holding parts connected to both sides of the central support member so as to sandwich the central support member. .

Since the solid lubricant applicator according to the present invention is configured as described above, the following effects can be obtained.
That is, since a total of four solid lubricants are provided for one flange portion of the wheel, sufficient lubricant is supplied to the flange portion to ensure smooth running of the traveling body. it can.

  An object of the present invention is to provide a solid lubricant coating device that applies a pair of solid lubricants on one side using a total of four solid lubricants.

Hereinafter, preferred embodiments of a solid lubricant coating device according to the present invention will be described with reference to the drawings.
The same parts as those in the conventional example are denoted by the same reference numerals, and the structure of the rotating arm and the like shown in FIGS. 7 to 14 is the same as the structure of the present invention, so that this is used.
In FIG. 1, a reference numeral 1 denotes a traveling body showing a part of a crane or the like, and a bolt 103 is provided in a recess 102 between a pair of holding tongue pieces 100, 101 formed on one surface of the traveling body 1. A bar-shaped central support member 104 is provided.

  First and second holding portions 6a and 6b are fixed to both sides of the lower portion of the central support member 104 by pins 105 so as to sandwich the central support member 104, and the central support member 104 and the respective holding portions 6a. , 6b constitutes a holding body 6 bent in a step shape as viewed in a plan view as shown in FIG. In addition, although this holding body 6 is formed in three bodies by the center support member 104, the whole body can also be bent and formed integrally.

A pair of first rotating arms 8 are indicated by an arrow A via a support shaft 7 having a spring member 10 such as a torsion spring on both sides of one end 6A of the holding body 6, that is, the end of the first holding portion 6a. They are spaced apart from each other in the axial direction so as to be urged to rotate along the direction.
On both sides of the other end 6B of the holding body 6, that is, the end of the second holding portion 6b, a pair of second rotating arms 9 are indicated by an arrow B via a support shaft 7 having a spring member 10 such as a torsion spring. They are spaced apart from each other in the axial direction so as to be urged to rotate along the direction shown.

  As seen from the right side of FIG. 1, the pair of first rotating arm 8 and second rotating arm 9 described above are the first, second, first, and second rotating arms 8 as shown in FIG. 2. , 9 are arranged alternately.

2 and FIG. 1 as viewed from above, as shown in FIG. 3, the pair of first rotating arms 8 and the pair of second rotating arms 9 are arranged in the longitudinal direction C of the holding body 6. The first and second rotating arms 8 and 9 are arranged in the orthogonal direction D perpendicular to the longitudinal direction C when viewed in a plane. The first rotating arms 9 and 8 are arranged in a staggered pattern in this order.
Therefore, even if a total of four said rotating arms 8 and 9 rotate in the direction shown by the arrow A and B, they are comprised so that it may not interfere with each other.

Further, FIGS. 4 and 5 show that the pair of first rotating arms 8 and the pair of second rotating arms 9 provided on the first and second holding bodies 6a and 6b of the holding body 6 are separated. The configuration is easy to understand.
In addition, since each solid lubricant 5 needs to be slidably contacted along the shape of the flange portion 4 of the wheel 2 for each of the support shafts 7 described above, it is necessary to use a shape bent slightly in the shape of a letter. .

  Moreover, the attaching / detaching structure for holding the solid lubricant 5 in each of the excessive arms 8 and 9 shown in FIGS. 1 to 5 is shown in FIGS. 6 to 14 of the conventional example as described above. Since this is the same as the configuration, this is used, and parts corresponding to those in FIGS. 1 to 5 are denoted by the same reference numerals, and description thereof is omitted to avoid duplication.

  The solid lubricant applicator according to the present invention is applicable not only to wheels such as cranes but also to transport vehicles in factories.
