  FIG. 1 is a perspective view showing the structure of an elevator provided with a guide rail maintenance device according to the present invention. As shown in this figure, an elevator car 20 moves up and down on a track of a substantially T-shaped guide rails 1 and 1 erected in opposition to a building, and includes a drive motor 2, It is driven up and down by an elevating drive device 7 comprising a hoisting roller 3, a hoisting rope 4, a counterweight 5, and a counterweight guide rail 6 for guiding the counterweight 5. Here, guide bodies 8 are installed at four positions, top, bottom, left, and right of the position where the car 20 contacts the guide rails 1 and 1. And the guide rail maintenance apparatus 9 and 9 which concern on this invention are installed in the position which can contact with the guide rails 1 and 1 of the upper surface of the passenger car 20.

  Next, the raising / lowering operation | movement of the passenger car 20 is demonstrated using FIG. The upper surface of the car 20 is connected to one end of the hoisting rope 4, and the car 20 is moved up and down by hoisting or lowering the hoisting rope 4 with the hoisting roller 3. The forward rotation or the reverse rotation of the winding roller 3 is performed by the rotation of the drive motor 2 in which the winding roller 3 and the rotation shaft are connected. The drive motor 2 is controlled by a control body (not shown) for moving the car 20 to a desired floor according to a command from an operating body installed on each floor.

  FIG. 2 is a perspective view showing the positional relationship between the guide rail maintenance device 9 and the guide body 8 according to the present invention. The guide bodies 8 installed at four places in the upper, lower, left, and right sides of the car 20 have substantially U-shaped fitting portions 8a that are in sliding contact with the sliding surface 1a of the guide rail 1. The guide rail maintenance device 9 fixed to two places on the upper surface of the car 20 is installed above the guide body 8 and at a position where it can come into contact with the guide rail 1. The guide rail maintenance device 9 can also be installed at a position below the guide body 8 and capable of contacting the guide rail 1.

  FIG. 3 is a cross-sectional view of the guide rail maintenance device 9 according to the present invention. As shown in this figure, the guide rail maintenance device 9 includes maintenance units 10a, 10b, and 10c that are independent of the guide surfaces (the right side surface 1a, the left side surface 1b, and the top surface 1c) that constitute the guide portion of the guide rail 1. It has been done. The oil-coated body 11 constituting the maintenance units 10a, 10b, and 10c is urged by the springs 12a, 12b, and 12c to be in dynamic contact with the guide surfaces 1a, 1b, and 1c.

  In addition, the porosity of the double structure used for the oil-coated body 11 described later is 70 to 20%, and the apparent density is in the range of 0.3 to 1.0 gram per cubic centimeter. When a double structure having a porosity of 55% and an apparent density of 0.45 grams per cubic centimeter is used, it can be used more suitably. Here, the void ratio is also referred to as a void ratio or a bubble ratio, and is a ratio of voids existing inside the material, and is expressed as a volume percentage. The apparent density is the mass per unit volume of the substance, and is expressed in grams per cubic centimeter. The standard temperature at the time of measuring the apparent density is usually 23 ° C.

  FIG. 4 is a perspective view of the maintenance unit 10 a constituting the guide rail maintenance device 9. As shown in this figure, the oil-coated body 11 has an oil-coated sheet 14 and an intermediate sheet 15 alternately stacked in the opening of the cover 13 in which the spring receiver 13a and the supply port 13b are formed. An oil supply sheet 16 is inserted from the supply port 13 b and comes into contact with the oil application sheet 14. Further, one end of each of the springs 12a, 12b, and 12c is inserted into the spring receiver 13a. Here, the end of the oil-coated sheet 14 has a structure that protrudes beyond the end of the intermediate sheet 15. This configuration solves the conventional problem that it becomes difficult to supply the lubricating oil to the guide rail if the lubricating oil is hardened to form a wall.

  FIG. 5 is a longitudinal sectional view of the guide rail maintenance device 9 according to the present invention. As shown in this figure, in the oil coating body case 9a, an oil supply tank 21 and an oil supply body storage chamber 17 are partitioned by a wall 18, and lubricating oil filled in the oil supply tank 21 by an oil supply sheet 16 is provided. Is supplied to the oil-coated sheet 14. As described above, the intermediate sheet 15 is not in contact with the fueling sheet 16. Further, an oil reservoir chamber 19 is provided at one end of the oil supply sheet 16 and below the oil coating sheet 14. Further, a lid 9b is installed above so that the lubricating oil does not spill due to vibration.

  FIG. 6 is a cross-sectional view of the oil body case 9a. As shown in this figure, the oil body case 9a is U-shaped when viewed in plan, and includes an oil supply tank 21, a right oil body storage chamber 17a, and a left oil body storage chamber 17b. The wall 18 is divided into a top surface oil body storage chamber 17c.

  FIG. 7 is a perspective view showing another example of the above-described maintenance unit. As shown in this figure, the maintenance unit 30 a has an oil coating body 31 and a cleaning body 36. The oil-coated body 31 is formed by alternately laminating oil-coated sheets 34 and intermediate sheets 35 in the opening of the cover 33 in which the spring receivers 33a and the supply ports 33b are formed. An oil supply sheet (not shown) is inserted from the supply port 33 b and comes into contact with the oil application sheet 34. One end of a spring (not shown) is inserted into the spring receiver 33a. Here, the end portion of the oil-coated sheet 34 has a structure protruding beyond the end portion of the intermediate sheet 35. Moreover, the cleaning body 36 can wipe off the dirt adhering to the guide rail. As the cleaning body 36, a brushed brush or a channel brush in which a brush piece is implanted on a base fabric is used.

  In the above-described embodiment, an example in which the maintenance unit includes only the oiled body or the oiled body and the cleaning body has been described. However, only the cleaning body can be applied. When the cleaning body is applied, the cleaning body can wipe off the dirt adhered to the guide rail by the end face portion or corner portion of the cleaning body. Further, similarly to the oil-coated body described above, the cleaning sheet and the intermediate sheet are alternately laminated, and the end of the cleaning sheet protrudes from the end of the intermediate sheet. Since it can be formed and is urged by a spring, the edge of the cleaning sheet can have an edge, and the dirt can be scraped off.

  FIG. 8 is a view showing a cross section of the double structure 61 used in the oiled body. In the double structure 61, a plurality of fiber bundles 40 in which a plurality of ultrafine fibers 39 are converged are formed to form a nonwoven fabric 43, and the fiber bundle 40 is foamed with extremely fine bubbles 42 around it. A polyurethane base 41 is formed. A gap 38 is formed between the adjacent ultrafine fibers 39. The ultrafine fibers 39 are made of synthetic fibers such as nylon and polyester and have a fineness of less than 1 dTx. In general, the ultrafine fibers 39 are called microfibers, and the fiber bundle 40 is called a sea-island structure.

  By comprising in this way, since lubricating oil can be retained in a space | gap part, an appropriate quantity of lubricating oil can be supplied to a guide rail. Further, when the bubbles 42 are continuous bubbles, the lubricating oil can also be retained in the bubbles 42.

  The main component of the non-woven fabric constituting the double structure used in the oil-coated body is one or more of polyamide fiber, polyester, polyethylene fiber, polypropylene fiber and urethane rubber fiber, and is used in the oil-coated body. The base part constituting the double structure is preferably a porous polyurethane having fine bubbles.

  The double structure 61 is manufactured by three-dimensionally knitting a fiber obtained by mixing and spinning a main component and subcomponents to form urethane, and then dissolving and removing the subcomponents. The double structure 61 includes a non-woven fabric and a base portion, and a void portion is formed between the non-woven fabric and the base portion, and a polyurethane base portion where no unreacted monomer is formed can be formed. The manufacturing method is not particularly limited.

  When the double structure 61 is used for the oil-coated bodies 11 and 31, the oil-coated bodies 11 and 31 have extremely high durability, and hardly undergo elastic deterioration, discoloration, yellowing, or the like. Moreover, since the base of polyurethane has high wear resistance, an oil-coated body excellent in durability can be produced. Moreover, since the base has extremely fine bubbles, the weight of the oil-coated body can be reduced, and the impact applied to the oil-coated body can be absorbed. Accordingly, the guide rail surface can be flexibly contacted, and the guide rail surface is not damaged.

  In addition, when a polyamide fiber typified by nylon is used as the nonwoven fabric constituting the double structure 61, the polyamide fiber has high wear resistance, heat resistance, and high chemical resistance from weak acid to strong alkali. The oil-coated bodies 11 and 31 can have characteristics such as oil resistance. In addition, when polyester is used, the oil-coated body can be provided with properties such as heat resistance of polyester and high chemical resistance from strong acid to weak alkali, oil resistance, and low price. Moreover, when polyethylene fiber is used, the oil coating bodies 11 and 31 can have characteristics such as high chemical resistance and low price in acid and alkali of the polyethylene fiber. Further, when polypropylene fibers are used, the oil-coated bodies 11 and 31 can have characteristics such as low price and light weight of the polypropylene fibers. In addition, when urethane rubber fibers, also called urethane elastic yarns, are used, it is possible to give the oil-coated bodies 11 and 31 properties such as the lipophilicity and elasticity that the urethane rubber fibers have.

  The guide rail maintenance device of the present invention is suitably used as a device for guiding the lifting and lowering of a passenger car such as an elevator and for cleaning and oiling the guide rail.
