Description

  The present invention relates to an oil supply device that supplies oil to an elevator rope.

  Conventionally, the rope that suspends the car and the counterweight is a hemp core wire rope, and the oil contained in the hemp core portion oozes out, so that only the lubricating action between the sheave of the hoist and the rope There was no rust prevention effect. However, in recent elevators, the application of a steel core rope has been expanded, and in the case of this steel core rope, oil from the steel core portion hardly oozes out. For this reason, it is essential to supply oil from the outside of the rope.

  Thus, as one method, there is a method of applying oil by hand during regular maintenance. However, it takes time and money, and there is a possibility that the amount of oil supply varies. In addition, as another method, there is a method of applying oil to a rope using an oil supply device without involving human hands. For example, Patent Document 1 below describes a method in which a felt is immersed in oil in a tank and the tip of the felt is contacted with a rope to supply oil.

JP 2006-21873 A (summary etc.)

  However, in the fueling device described in Patent Document 1, since only one piece of felt having a flat contact surface with the rope is provided, the felt contacts only at a limited position on the outer periphery of the rope. There is a possibility that only a limited part on the outer circumference of the rope can be refueled.

  The objective of this invention is providing the rope oil supply apparatus which can be supplied so that oil may spread widely on the outer periphery of a rope, and an elevator provided with the same.

In order to achieve the above object, the present invention includes a tank for storing oil and an oil retaining piece having a contact surface with an elevator rope at the tip, and the oil in the tank is inserted into the rope via the oil retaining piece. In the elevator rope oil supply apparatus, a plurality of the oil retaining pieces are provided at different height positions, and at least some of the plurality of oil retaining pieces have a horizontal cross section of a contact surface inclined with respect to each other. it shall be the feature of the you are.

As shown in FIG. 1, a rope 2 is wound around a sheave 4 of a hoisting machine, and an elevator rope oiling device is installed on a support base 30 of the hoisting machine via a bracket 8 or the like. The rope 2 is a steel core rope, and one end side and the other end side of the rope 2 are configured to reach a car and a counterweight (not shown). It is driven through the sheave 4 of the hoisting machine.

Next, the configuration of the elevator rope oil supply device will be described. First, an elevator rope oil supply apparatus according to the present embodiment mainly includes a tank 5 that accumulates oil, an oil retaining portion 1 that adsorbs oil and supplies the oil to the rope 2, and an oil retaining portion that supplies oil from the tank 5. 1 is composed of a pipe 24 that transmits to 1. Here, as the oil supplied to the rope 2, for example, viscous grease having a kinematic viscosity at 40 ° C. of about 440 to 480 mm ² / s is used. This grease has a higher kinematic viscosity than general oil supplied to an elevator rope, and can reduce the risk of oil scattering and adhering to a brake or the like even in a high-speed elevator.

  In addition, an oil supply amount adjusting means for dropping a predetermined amount of oil by gravity within a predetermined time is provided at the lower part of the tank 5 to automatically adjust the amount of oil discharged to the pipe 24. In addition, an oil pan 10 is installed below the oil retaining unit 1 as a tray when oil leaks. Furthermore, one end of the bracket 8 is fixed with a bolt 7 to a support 3 that is integrally formed with the support base 30 of the hoisting machine, and the oil retaining portion 1 is attached to the bottom of the bracket 8. .

  The configuration of the oil retaining unit 1 will be described more specifically with reference to FIGS. First, as shown in FIG. 2, the oil retaining portion 1 of the present embodiment includes a case 12 in which a bottom surface and both side surfaces are formed by bending a metal plate, and a first oil retaining piece 20 accommodated in the case 12. , 21, 22 and the second oil retaining piece 19, and the upper lid 15 covering the upper part of the case 12. Further, ribs 13 as shown in FIGS. 3 (a) and 3 (b) are welded in the vicinity of both ends of the side of the case 12 where the both side surfaces are not formed, and oil leaks. It prevents it from coming out. A bracket 14 is provided on the upper portion of the pair of ribs 13, and the bracket 14 has a hole 31.

  Further, as shown in FIG. 3 (b), a plurality of openings (specifically, the same number as the number of ropes 2) are provided on one of both side surfaces of the case 12, and a later-described holding member is provided. It is comprised so that a part of oil piece can protrude. Further, the bottom surface of the case 12 has a long hole 27 and is supported so as to be slidable with respect to the bottom of the bracket 8, and the distance between the entire case 12 and the rope 2 can be adjusted by the adjuster bolt 25. ing.

  Next, the configuration of the upper lid 15 will be described in detail with reference to FIGS. 4 (a) and 4 (b). First, the main body of the upper lid 15 is bent to increase the strength, and holes 32 are provided near both ends of the upper lid 15 in the longitudinal direction and above the ribs 13 of the case 12. By fixing the hole 32 and the hole 31 of the bracket 14 with bolts, the upper lid 15 is prevented from being detached from the case 12 due to elevator vibration or the like. In addition, another hole 33 is provided in the upper lid 15, and the pipe 24 from the tank 5 is inserted into this hole 33. In this embodiment, two holes 33 are provided at positions where the longitudinal dimension from one rib 13 to the other rib 13 is divided into a ratio of 1: 4: 1. By providing the hole 33 at such a position, the uniformity of the oil flowing in from the pipe 24 in the case 12 can be improved. Furthermore, nine rods 16, which are the same as the number of ropes 2, are attached to the upper lid 15 via bolts 17, and the tips of these rods 16 are chamfered to support an oil retaining piece to be described later.

  FIG. 5 shows one configuration of the oil retaining piece assembly 18 placed in the case 12. The oil retaining piece assembly 18 of the present embodiment is formed of four types of oil retaining pieces 19 to 22, the first oil retaining piece 20 in the second layer from the top, and the fourth in the fourth layer from the top. The first oil retaining piece 21, the first oil retaining piece 22 in the sixth layer from the top, and the second oil retaining piece 19 in the third and fifth layers from the top are located. Each oil retaining piece has a through hole so that the oil penetrates from the upper oil retaining piece to the lower oil retaining piece. In this embodiment, considering the workability when attaching the oil retaining piece assembly 18, the oil retaining portion 1 is configured by arranging three oil retaining piece assemblies 18 in the case 12. The oil retaining part 1 may be constituted by two oil retaining piece assemblies 18.

  Here, the first oil retaining piece 20 is formed of felt or the like using an oil-absorbing material, and includes a laminated portion constituting the main body and projecting portions 20a, 20b, and 20c extending to the rope 2 side. In addition, a contact surface with the rope 2 is provided at the tip of the projecting portions 20a, 20b, and 20c. Similarly, the first oil retaining pieces 21 and 22 are both formed of felt or the like, and their tips protrude for each rope 2 and have contact surfaces independent of each other. Note that the contact surfaces of the first oil retaining pieces 20, 21, 22 are shaped such that their horizontal cross sections are inclined with respect to each other as shown in FIGS. 6 (a), 6 (b), and 6 (c). Yes. That is, since the plurality of first oil retaining pieces 20, 21, and 22 provided at different height positions are in contact with different positions on the outer periphery of the rope 2, Can spread the oil widely. Here, the object to which the first oil retaining pieces 20, 21, 22 of the present embodiment directly supply oil is only the semicircular portion of the outer periphery of the rope 2, but this portion is as shown in FIG. Since the portion faces the groove of the sheave 4 of the hoisting machine, the lubricating action between the rope 2 and the sheave 4 can be ensured. In addition, when a roping is adopted in which the winding direction of the rope 2 is changed by a predetermined pulley other than the sheave 4 and it is necessary to supply oil directly to the entire circumference of the rope 2, It is also conceivable to provide a plurality of oil retaining sections 1.

  Further, since at least a part of the contact surface of the first oil retaining piece 20, 21, 22 is covered with the wear-resistant member 23, wear due to contact with the rope 2 can be reduced, and the rope 2 It is possible to suppress the change in the contact state with. The wear-resistant member 23 is made of a plastic such as polyester or nylon, and is formed in a mesh shape so as to ensure oil permeability.

  In addition, the length of the protrusion part of the 1st oil retaining piece 20,21,22, ie, the length from the lamination | stacking part side end of a protrusion part to the center of a contact surface, is the rope 2 from the lamination | stacking part side end of a protrusion part. Longer than the distance to the center. For this reason, the tip of the protrusion is elastically deformed upward or downward following the movement of the rope 2 while constantly contacting the rope 2. For this reason, compared with the case where the oil retaining member is not elastically deformed and the rope 2 is pressed with a strong force, the wear resistance is improved, and the work of adjusting the positional relationship with the rope 2 according to the wear of the oil retaining member. Can be suppressed.

  Next, the second oil retaining piece 19 is also formed of felt or the like using an oil-absorbing material, but unlike the first oil retaining pieces 20, 21, and 22, it does not have a protruding portion. It is composed only of the laminated part. Here, since the second oil retaining piece 19 does not need to form a contact surface with the rope 2, the material is made of a material having higher oil absorption than the first oil retaining pieces 20, 21, 22; For example, a kapok material can be used. Then, even if the tank 5 is not provided, it is possible to supply an elevator rope oil supply apparatus that can supply oil for a long period of time and that prevents excessive oil supply.

  In the present embodiment, the first oil retaining pieces 20, 21, 22 are not stacked and stacked, and the first oil retaining pieces 20, 21, 22 and the second oil retaining pieces 19 are alternately arranged. Therefore, even if the first oil retaining pieces 20 to 22 are elastically deformed following the movement of the rope 2, they do not interfere with each other, and stable oil supply performance can be maintained. . In the present embodiment, the oil retaining member is not directly immersed in the oil in the tank 5, and the case 12 for storing the oil retaining member and the tank 5 for storing the oil are installed in separate locations. Since the oil retaining member is indirectly refueled via the above-described refueling amount adjusting means, excessive refueling of the rope 2 can be prevented.

  In the present embodiment, the same number of openings as the number of the ropes 2 are provided on the side surface of the case 12, but the protrusions of the first oil retaining pieces 20, 21, and 22 are provided for each rope 2. As long as it can displace independently, the structure which made the several protrusion part for every rope 2 protrude from the common opening part may be sufficient. Further, in this embodiment, the oil retaining piece assembly 18 is configured by using three types of first oil retaining pieces, each of which has a horizontal cross-sectional shape of the contact surface that is inclined with respect to each other. The oil retaining piece assembly 18 may be configured by using the first oil retaining pieces one by one. Furthermore, it is sufficient that at least some of the plurality of first oil retaining pieces provided at different height positions have their horizontal cross-sections of the contact surfaces inclined with respect to each other. The oil retaining piece assembly 18 may be configured by using a plurality of pieces. Further, as the horizontal cross-sectional shape of the contact surface of the first oil retaining piece 20, 21, 22 as shown in FIG. 6 (d) instead of (a), (b), (c) in FIG. A circular groove shape can also be used.
