Description

  The present invention relates to an elevator rope oil supply device, and more particularly to an elevator rope oil supply device for supplying oil to a rope for suspending a car.

  In general, an elevator car is suspended by a rope and lifted and lowered along a guide rail in a hoistway by a hoisting machine. In order to supply oil to this rope, a rope oil supply device is used.

  FIG. 7 shows a conventional elevator rope oiling apparatus. As shown in FIG. 7, a conventional elevator rope oil supply device 100 includes an oil case 101 and a felt 102, and oil 103 is accommodated in the oil case 101. An intermediate portion 104 of the felt 102 is curved, one end 105 side of the felt 102 is inserted and immersed in the oil 103, and the other end 106 side of the felt 102 is initially roped by a pressing amount of about several mm. 110 is pressed against.

  However, in the conventional elevator rope oiling device described above, the other end 106 side of the felt 102 is initially pressed against the rope 110 by a pressing amount of about several millimeters. As the rope contact surface of the other end portion 106 of the felt 102 wears as it travels in the road, a gap is generated between the rope contact surface of the other end portion 106 and the outer peripheral surface of the rope 110. For this reason, oil supply from the felt 102 to the rope 110 cannot be reliably performed, and the oil supply efficiency to the rope 110 is deteriorated.

  Thus, when the oil supply efficiency to the rope 110 is deteriorated, the amount of oil contained in the rope 110 is reduced, and as a result, the aggression to members such as a sheave (not shown) with which the rope 110 contacts is increased, There is a risk of causing excessive wear on a member such as a sheave.

  Further, in order to maintain the lubrication efficiency of the rope 110, even if the elevator car travels in the hoistway, the contact state between the contact surface 107 of the other end 106 of the felt 102 and the outer peripheral surface of the rope 110 is maintained. There is always a need to maintain. In order to always maintain the contact state between the felt 102 and the rope 110, it is necessary to perform position adjustment work such as periodically moving the position of the other end portion 106 of the felt 102 to the rope 110 side, and the work becomes complicated. .

  Moreover, in the conventional elevator rope oiling device disclosed in Patent Document 1, the rope is supported by a pair of oiling rollers while the rope is sandwiched between the pair of oiling rollers, and the oiling pipe and the oiling hose are supported. Since it is necessary to supply oil to the pair of oil supply rollers using the oil supply pump, the structure of the elevator rope oil supply device is complicated and the size thereof is increased.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to prevent an increase in size, to reliably and stably supply oil to the rope, and to increase the efficiency of supplying oil to the rope. An elevator rope oil supply apparatus can be provided.

  The elevator rope oil supply apparatus of the present invention is an elevator rope oil supply apparatus that supplies oil to a rope that suspends a passenger car, and includes an oil storage part that stores the oil, and a material that absorbs the oil in the oil storage part.
