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

  FIG. 1 is a schematic configuration diagram of the first embodiment, and FIGS. 2A and 2B are perspective views of the first embodiment.

 In the machine room 2 above the hoistway 1, a hoisting machine 4 is fixed to a machine beam 3 installed on the floor. A rope 6 (object) is suspended from the sheave 5 of the hoisting machine 4. A cage 7 is connected to one end of the rope 6, and a weight 8 is connected to the other end. The machine beam 3 is provided with a rope oil feeder 9. The rope oil feeder 9 is disposed in the vicinity of the rope 6 that is substantially suspended from the sheave 5.

  With reference to FIG. 2 (a), (b), the structure of the rope oil feeder 9 is demonstrated.

  The rope oil feeder 9 includes a base 11 having a notch, an oil tank 12 having an opening on one surface, a cover 13 provided so as to cover a part of the opening of the oil tank 12, and an oil 14 on the rope 6. Felt 15 to be supplied (oil supply portion), felt support portion 16 for supporting the felt 15 to the oil tank 12, and an adjuster bolt that is fixed to the end of the base 11 and is in contact with the outer wall of the oil tank 12 17 (adjustment unit). The cover 13 has a substantially U-shaped longitudinal section.

  The base 11 is fixed to the machine beam 3 with a bolt or the like using the notch of the base 11. An oil tank 12 is fixed to the base 11 with bolts or the like. An adjuster bolt 17 is disposed on the base 11 at a position where it can contact the side surface of the oil tank 12. The adjuster bolt 17 can move the oil tank 12 in one direction by contacting the oil tank 12. For example, two adjuster bolts 17 are arranged at a predetermined distance from one side surface of the oil tank 12.

  Oil 14 is filled in the oil tank 12. The felt 15 is fixed by a bolt so as to be sandwiched between the sleeve portion 18 and the fixing plate 19 of the oil tank 12. One end of the felt 15 is immersed in the oil 14 and the other end is disposed so as to contact the rope 6.

  A cover 13 is provided so as to be openable and closable so as to cover the opening of the oil tank 12. The cover 13 is movable along a cover opening / closing support portion 20 such as a bolt disposed on a pair of side surfaces of the oil tank 12. The cover opening / closing support part 20 is provided so as to pass through a long hole 21 provided in the vicinity of both ends of the cover 13. The shape of the long hole 21 is substantially L-shaped.

  Such attachment and adjustment of the rope lubricator 9 will be described with reference to FIG.

  Before the rope oil feeder 9 is attached to the machine beam 3, at least the base 11, the oil tank 12, the cover 13, and the felt 15 are assembled together. The felt 15 is adjusted so as to protrude from the fixed plate 19 by several to several tens of mm.

  The rope oil feeder 9 assembled in such a state is first fixed to the machine beam 3 with bolts.

  At this time, the tip of the felt 15 may or may not be in contact with the rope 6.

  Next, by turning the adjuster bolt 17, the tip thereof contacts the outer wall of the oil tank 12. The oil tank 12 can be moved closer to the rope by a predetermined amount by continuing to turn the adjuster bolt 17 even after contact. Then, by moving the oil tank 12, the tip of the felt 15 contacts or bites into the rope 6. In the case of excessive biting, the adjuster bolt 17 is rotated in the reverse direction to create a gap between the adjuster bolt 17 and the old tank 17, and the oil tank 12 is moved away from the rope 6. The movement in this case is manual.

  The contact amount between the rope 6 and the felt 15 can be appropriately set by operating the adjuster bolt 17.

  The oil 14 can be supplied by the tip of the felt 15 coming into contact with the rope 6.

  The timing of pouring the oil 14 into the oil tank 12 varies depending on the type of the oil 14 and the felt 15 and the installation environment. For example, before and after installing the machine beam 3 depending on the penetration rate into the felt 15. It can be set appropriately.

  If the oil 14 is put into the oil tank 12 before being installed on the machine beam 3, the oil 14 is added to the oil tank 12 if the cover 13 is used to cover the opening of the oil tank 12. There is no leakage outside.

  Further, when the oil 14 is put into the oil tank 12 after being installed on the machine beam 3, the oil tank 12 can be covered with the cover 13.

  The opening / closing operation | movement of the cover 13 is demonstrated with reference to the side view of Fig.4 (a) (b).

  FIG. 4A shows a state where the cover 13 is open, and FIG. 4B shows a state where the cover 13 is closed.

  As shown in FIG. 4A, the initial position when fully opened is such that the back surface 31 of the top surface of the cover 13 faces the one side surface 32 of the oil tank 12. The cover 13 is supported by a cover opening / closing support portion 20, moves upward in the figure along the long hole 21 with the support portion 20 as a support shaft, and can rotate approximately 90 degrees to the right in the figure. Alternatively, it can be rotated approximately 90 degrees clockwise from the initial position, and can be moved approximately horizontally in the right direction in the figure (cover 13 of the dotted line in FIG. 4 (b)).

  And as shown in FIG.4 (b), the cover 13 will be in a horizontal state, will cover the opening part of the oil tank 12, and will be in a fully closed state. In the fully closed state, the cover opening / closing support portion 20 is fitted into one end 33 of the elongated hole 21 so as to fall. In this state, the cover 13 does not easily move (cannot be removed) due to its own weight.

  The rope oil feeder having such a configuration can always supply the oil 14 impregnated in the felt 15 to the rope 6 in contact with the felt 15 by raising and lowering the cage. The oil tank 12 is replenished with oil 14 as needed during maintenance.

  In addition, when making the contact state of the felt 15 and the rope 6 into a more favorable state by aging etc., it can change suitably by adjusting the adjuster bolt 17. FIG.

  Further, not only the adjuster bolt 17 is operated, but if possible, the contact state can be changed by adjusting the felt support portion 16 or moving the base 11.

  With such a configuration, the first embodiment of the present invention can be easily adjusted in the field even when the rope 6 and the felt 15 are not in contact with each other due to various errors. Further, there is no place depending on the experience of the worker, and the workability and safety can be improved.

(Second embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. In the following embodiments, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  A feature of the second embodiment is that a mesh 35 (net-like member) is provided at the bottom of the oil tank 12.

  FIG. 5 is a cross-sectional view of the oil tank according to the second embodiment.

  A mesh 35 is provided in the vicinity of the bottom of the oil tank 12 in a substantially horizontal direction. The size of the opening 36 of the mesh 35 can be variously selected by the user.

  The dust that has entered the oil tank 12 falls from the opening 36 of the mesh 35 to the bottom and settles. Therefore, it is possible to suppress dust from adhering to the felt 15 and to prevent the felt 15 from absorbing the oil 14.

  Next, a third embodiment of the present invention will be described with reference to FIG.

  A feature of the third embodiment is that a felt tip support portion 37 (posture support portion) for directing the posture of the tip portion is provided below the tip portion of the felt 15 that contacts the rope 6.

  FIG. 6 is a cross-sectional view of the oil tank according to the third embodiment.

  A felt tip support portion 37 is attached to the upper portion of the side surface 38 of the oil tank 12 with a screw 39 or the like. In the drawing, the felt tip support portion 37 is set in a substantially upper left direction, but can be set to an appropriate angle in the vertical direction in the drawing by changing the angle of the felt tip support portion 37. The felt tip support portion 37 is made of, for example, aluminum or steel, but may be any material as long as it supports the direction in which the felt 15 is directed and is resistant to the oil 14.

  Further, the tip of the felt tip support portion 37 on the rope 6 side is set so as not to protrude from the felt 15 without fail. This is because only the felt 15 is brought into contact with the rope 6.

  Next, a fourth embodiment of the present invention will be described with reference to FIG.

  A feature of the fourth embodiment is that a gauge 40 is provided on the upper surface of the base 11.

  FIG. 7A is a top view of the oil tank according to the fourth embodiment, and FIG. 7B is a top view of the gauge.

  As shown in FIG. 7A, a gauge 40 is provided on the upper surface of the base 11 and in the vicinity of the side surface of the oil tank 12. The gauge 40 is fixed to the base 11 by welding or screws.

  As shown in FIG. 7B, the gauge 40 displays in advance the amount of movement due to the diameter of the rope, for example. An oil tank position display 41 such as an “arrow” indicating the initial position of the oil tank 12 is provided on the side surface of the oil tank 12.

  The operator can move the oil tank 12 to a desired position by rotating the adjuster bolt 17 while looking at the gauge 40 and the oil tank position display unit 41.

  Although the diameter of the rope is displayed on the gauge 40, it may be 0, 10, 20, 30,... [Mm] or the like so that the amount of movement from the initial position can be seen purely.

  With such a configuration, the workability of the worker is improved.

  In addition, this invention is not limited to each above-mentioned embodiment, A various deformation | transformation is possible in the range which does not deviate from the main point.

  For example, it is possible to provide the oil tank 12 with a window so that the amount of the oil 14 can be seen from the outside without opening the cover 13. Alternatively, an approximately L-shaped transparent thin tube may be provided on the side surface of the oil tank 12 to visually grasp the amount of the oil 14. At this time, one end of the thin tube connected to the oil tank 12 is always arranged so as to be immersed in the oil 14. The oil 14 passes through the narrow pipe and reaches the same height as the liquid level in the oil tank 12.

  Further, a plurality of felts 15 can be arranged in the oil tank 12 as necessary. For example, two felts 15 can be arranged so as to face each other, or four felts can be arranged on four side surfaces.

  Further, instead of the felt support portion 16 and the felt tip support portion 37, as a centering mechanism of the felt 15, a set of rollers may be arranged so as to sandwich the felt 15. By rotating the roller, the felt 15 can be moved in a desired direction by a predetermined amount by the frictional force. The rotating shaft of the roller is supported by an oil tank, and the roller is formed of resin or the like.

  Moreover, although the fueling device was installed in the machine room, it can also be installed in an elevator without a machine room. In that case, any position in the hoistway can be used as long as oil can be supplied to the rope. For example, it can be installed on guide rails, hoisting machine support members, various brackets, pits, counterweights, etc. Is possible.

  Moreover, you may make a notch | incision in the rope contact position of felt as needed.

  Further, the number of ropes contacting the felt may be any number. Further, the number of adjuster bolts may be any number.

  Also, if the rope diameter is 20 mm or less, particularly 10 mm or less, the amount of oil impregnation of the rope itself is reduced, so it is better to always supply oil. Depending on the rope diameter and material, the supply of oil by the rope oil feeder of the present invention may be essential.
