FIG. 4A is a diagram relating to the closed state, and FIG. It is a figure regarding a state.

  The cleaning device 103 according to the first embodiment corresponds to a configuration in which the guide surface of the guide rail 100 placed on the floor before being installed on the elevator hoistway is cleaned by manual operation (manual operation). However, the guide rail 100 includes a car and a counterweight.

  Referring to each drawing, the cleaning device 103 includes, as a base member, a fixed base plate 1 and a movable base plate 2 that straddle the convex portion of the elevator guide rail 100, and is provided at two locations in the longitudinal direction of the device. The upper base plate 8 is provided. The fixed side base plate 1 and the movable side base plate 2 are respectively provided with side rollers 3a and 3b for applying a solvent to the side surface of the convex portion of the guide rail 100, side scraper mounting bases 4a and 4b, and a tension spring 16. Posts 5a and 5b for attachment are attached. The fixed base plate 1 and the movable base plate 2 have side guide rollers 6 a and 6 b that are in contact with the side surfaces of the guide rail 100, and a guide plate that serves as a guide when the apparatus main body is attached to the guide rail 100. 7 and 2 are attached in the longitudinal direction.

  In other words, the side roller 3a, the side scraper mounting base 4a, the post 5a, the side guide roller 6a, and the guide plate 7 are attached to the fixed side base plate 1. A side roller 3b, a side scraper mounting base 4b, a post 5b, a side guide roller 6b, and a guide plate 7 are attached to the movable base plate 2.

  The fixed base plate 1 is fixed to the upper base plate 8. In addition, an opening / closing operation clamp 9 is attached to the fixed-side base plate 1. A handle 14 is attached to the surface of the two upper base plates 8, and a top surface roller 10 that contacts the top surface of the convex portion of the guide rail 100 and applies a solvent to the back surface on the opposite side. It is attached. The upper base plate 8 includes a top surface scraper mounting base 11 disposed on the top surface of the guide rail 100, a top surface guide roller 12 that abuts on the top surface of the guide rail 100, and a side surface roller. A tank 13 for supplying a solvent to the rollers 3a and 3b and the top roller 10 is attached. Further, two short rails 15 are attached to the upper base plate 8 so as to extend in the longitudinal direction of the guide rail 100 in a direction perpendicular to the longitudinal direction of the guide rail 100, and are movable below the upper base plate 8. A side base plate 2 is attached.

  A tension spring 16 is attached to the posts 5a and 5b, and the fixed base plate 1 and the movable base plate 2 are attracted to each other with a constant force, as shown in FIG. 4A. The fixed-side base plate 1 and the movable-side base plate 2 have an opening / closing mechanism that opens and closes by operating the opening / closing operation clamp 9.

  As shown in FIG. 4B, the opening / closing mechanism can perform a raising operation against the spring force of the tension spring 16 of the clamp 9 for opening / closing operation. In this state, the movable side base plate 2 is in an open state with respect to the fixed side base plate 1, and the convex portion of the guide rail 100 can be fitted. On the other hand, as shown in FIG. 4A, the opening / closing mechanism can perform a tilting operation that applies the spring force of the tension spring 16 of the clamp 9 for opening / closing operation. In this state, the movable-side base plate 2 is closed with respect to the fixed-side base plate 1, sandwiching both side surfaces of the convex portion of the guide rail 100, and side guide rollers 6a provided at the sandwiched portions, 6b is brought into contact with both side surfaces of the convex portion of the guide rail 100.

  FIG. 5 is a top view showing a part of a schematic configuration for cleaning both side surfaces of the guide rail 100 which is a main part of the cleaning device 103 and is broken. FIG. 6 is a side view showing a part of the schematic configuration for cleaning the top surface of the guide rail 100 which is a main part of the cleaning device 103, and is broken.

  Referring to FIG. 5, metal side scrapers 18a and 18b and resin side wipers 19a and 19b are attached to the side scraper mounting bases 4a and 4b. The side scraper mounting bases 4a, 4b are pressed inwardly toward the guide rail 100 by a constant force by the opposing compression springs 20a, 20b. The lengths of the compression springs 20a and 20b can be adjusted by adjusting bolts 21a and 21b. Thereby, the pressing force of the side scrapers 18a and 18b can be adjusted. The side scrapers 18 a and 18 b are preferably metal thin metal plates having a hardness lower than that of the guide rail 100. The side wipers 19a, 19b may be made of a material such as rubber having flexibility other than resin.

  The side scrapers 18a and 18b and the side wipers 19a and 19b are attached to both sides of the side surface of the convex portion of the guide rail 100. Therefore, the apparatus is moved in the moving direction indicated by the arrow, and the solvent 101 is applied to the side surface of the guide rail 100 by the side rollers 3a and 3b. The object to be cleaned including the rust preventive oil dissolved by the solvent 101 and the foreign matter 102 such as dirt and solid matter is removed by the side scrapers 18a and 18b and the side wipers 19a and 19b.

  However, the spring force of the tension spring 16 described above needs to be larger than the spring force of the compression springs 20a and 20b attached to the side scraper mounting bases 4a and 4b. For example, when the force of the compression springs 20a and 20b of the side scraper mounting bases 4a and 4b is 1 kgf, the spring force of the tension spring 16 may be set to about 3 kgf. With these settings, the side guide rollers 6a and 6b can be kept in contact with the side surface of the guide rail 100 even when the apparatus is operated manually.

  The thickness of the side scrapers 18a, 18b is preferably about 0.2 mm so that the corners always abut against the side surface of the guide rail 100. The tips of the side scrapers 18a and 18b facing the moving direction indicated by the arrows are maintained at an acute angle so as to surely contact the side surface of the guide rail 100. The thicknesses of the side surface wipers 19a and 19b are also preferably set to 2 mm or more so that the corners are surely in contact with the side surfaces of the guide rail 100. The distal ends of the side wipers 19a and 19b facing away from the moving direction are also maintained at an acute angle so as to surely contact the side surfaces of the guide rail 100. Moreover, in order to suppress that the removal amount with respect to the antirust oil by wear of the corner | angular part of the side surface wipers 19a and 19b is suppressed, it is preferable that pressing force shall be about 1 kgf. Desirably, the side wipers 19a and 19b are made of wear-resistant silicon rubber, urethane rubber, or the like.

  In any case, the corners of the side surface wipers 19a and 19b are worn by sliding in contact with the side surface of the guide rail 100, and the removal amount of rust preventive oil tends to be reduced. On the other hand, since the contact surface that contacts the guide rail 100 is formed by a certain amount of wear, it is considered that the reduction in the removal amount of the rust preventive oil is suppressed.

  By the way, as shown in FIG. 5, the side scrapers 18 a and 18 b and the side surface wipers 19 a and 19 b have the tips that first contact the side surfaces of the convex portions of the guide rail 100. Therefore, it is preferable that the side scrapers 18a and 18b are attached to the rear side in the moving direction of the apparatus, and the side wipers 19a and 19b are attached to the front side in the moving direction of the apparatus so as to be inclined. . That is, the side scrapers 18 a and 18 b can efficiently scrape off the cleaning object including the foreign matter 102 attached to the side surface of the guide rail 100 to the lower side of the guide rail 100. Further, the cleaning object and the solvent remaining on the side surfaces of the guide rail 100 after the removal processing by the side scrapers 18a and 18b can be removed by the side wipers 19a and 19b.

  Referring to FIG. 6, a top scraper mounting base 11 is provided with a metal top scraper 22 and a resin top wiper 23. Therefore, the apparatus is moved in the moving direction indicated by the arrow, and the solvent 101 is applied to the top surface of the guide rail 100 by the top surface roller 10. A cleaning object including rust preventive oil dissolved by the solvent 101 and foreign matter 102 such as dirt, solid matter and the like is removed by the top surface scraper 22 and the top surface wiper 23. The top surface scraper 22 is preferably a metal thin metal plate having a lower hardness than the guide rail 100. The top surface wiper 23 may be made of a material such as rubber having flexibility other than resin.

  Similarly to the side scrapers 18a and 18b, the pressing force of the top surface scraper 22 may be controlled by a spring. In general, the guide rail 100 has a lower surface roughness on the top surface than on the side surface. . For this reason, what is necessary is just to adjust with respect to the lower surface of the scraper mounting base 11 for top surfaces so that the allowance of the side surface scrapers 18a and 18b and the side surface wipers 19a and 19b may be set to about 1 mm. The tip of the top scraper 22 that faces in the moving direction indicated by the arrow is maintained at an acute angle so as to surely contact the side surface of the guide rail 100. The tip of the top surface wiper 23 that faces in the direction opposite to the moving direction is also maintained at an acute angle so as to surely contact the side surface of the guide rail 100.

  The top surface scraper 22 has a contact portion at the front end disposed in the front side in the movement direction of the apparatus, and an extension portion is attached obliquely on the rear side in the movement direction of the apparatus. The object to be cleaned can be made to flow on the side surface of the guide rail 100. Thereafter, the object to be cleaned can be dropped to the lower side of the guide rail 100 by the side scrapers 18 a and 18 b on the side surfaces of the guide rail 100. The top surface wiper 23 may be attached so that the front end of the top surface of the guide rail 100 hits first and the extending portion is inclined forward in the moving direction of the apparatus. In the cleaning device 103 according to the first embodiment, the top surface scraper mounting base 11 can be brought into contact with the top surface of the guide rail 100 and cleaned in a state where the position is determined.

  FIG. 7 is a side view showing the solvent 101 supply mechanism in the cleaning device 103 with a part thereof broken.

  Referring to FIG. 7, the tank 13 that stores the solvent 101 supplies the solvent 101 to the side rollers 3 a and 3 b and the top roller 10 through the on-off valve 25. For this reason, the on-off valve 25 is provided in the vicinity of the top surface of the convex portion of the guide rail 100. The hose 24 serving as a supply pipe coupled to the on-off valve is disposed at a position where the tip portion can supply the solvent 101 with respect to the surfaces of the side rollers 3a and 3b and the top roller 10. . Examples of the solvent 101 include a case where an organic solvent is used. The material of the side rollers 3 a and 3 b and the top roller 10 may be any material that has corrosion resistance to the solvent 101.

  The on-off valve 25 is controlled to open and close by the expansion and contraction of the compression spring 26. The on-off valve 25 presses the apparatus main body against the guide rail 100 to release the compression spring 26. During that time, a certain amount of the solvent 101 is applied to the side rollers 3a and 3b and the top roller 10 from the hose 24. Supplied. Further, when the apparatus main body is removed from the guide rail 100, the on-off valve 25 is closed by extending the compression spring 26 and the supply of the solvent 101 is shut off.

  The cleaning device 103 having such a configuration is such that a plurality of guide rails 100 are placed on the floor so that the top surface is on the top before the elevator is installed, and the open / close operation clamp 9 is raised to raise the stationary base plate 1 and The interval between the movable base plates 2 is widened. After the apparatus main body is placed on the guide rail 100, the opening / closing operation clamp 9 is tilted, and the guide rail 100 is sandwiched between the side guide rollers 6 a and 6 b by the spring force of the tension spring 16, and the apparatus main body is inserted into the guide rail 100. Determine the relative position of. In this way, the cleaning preparation is completed.

  When the cleaning preparation is completed, the side scrapers 18a and 18b and the side wipers 19a and 19b attached to the side scraper mounting bases 4a and 4b are moved to the side of the guide rail 100 by the spring force of the compression springs 20a and 20b. It is pressed with a certain force. In this state, when the apparatus main body is pressed from above the top surface of the guide rail 100 by manual operation, the top surface scraper 22 and the top surface wiper 23 come into contact with the top surface of the guide rail 100, and the tank 13 is opened and closed. The valve 25 is pushed. As a result, the on-off valve 25 is opened, and the solvent 101 is supplied to the side rollers 3 a and 3 b and the top roller 10 through the hose 24.

  Therefore, the apparatus main body is moved in the longitudinal direction of the guide rail 100 with the side rollers 3a and 3b and the top roller 10 at the leading side. At this time, the solvent 101 is applied to the guide surface of the guide rail 100, and the cleaning object including the rust preventive oil adhering to the guide rail 100 and foreign matter 102 such as dirt, solid matter and the like is dissolved by the solvent 101. Thereafter, the cleaning object including the melted foreign matter 102 is scraped off by the side scrapers 18a and 18b and the top surface scraper 22. Further, the solvent 101 remaining on the guide surface of the guide rail 100 and the object to be cleaned are wiped off by the side surface wipers 19 a and 19 b and the top surface wiper 23. As a result, the cleaning object is removed from the guide surface of the guide rail 100.

  That is, the cleaning device according to Embodiment 1 has a configuration in which a roller for applying a solvent, a scraper, and a wiper are arranged in order and attached to the base member. The object to be cleaned attached to the guide surface is cleaned by moving the apparatus main body in the longitudinal direction of the guide rail with the roller at the head side. At this time, the roller applies the supplied solvent to the guide surface, the scraper scrapes off the cleaning object including the rust preventive oil and the foreign matter 102, and the wiper removes the remaining solvent 101 and the cleaning object. To pay off. For this reason, there is a remarkable effect that the guide surface of the guide rail can be cleaned stably and efficiently compared to the conventional case.

  In the case of the cleaning device according to the first embodiment, the rust preventive oil is particularly effectively removed because the guide surface of the guide rail before being installed on the hoistway is cleaned.

Embodiment 2. FIG.
The cleaning device 103 according to the first embodiment has been described with reference to the case where the guide rail 100 in a state of being placed on the floor before being installed on the elevator hoistway is manually cleaned. The cleaning devices 103a and 103b according to the second embodiment target the guide surface of the guide rail 100 after being installed in the hoistway, and are attached to the lower side of the car 27 to increase the normal operation of the car 27. Cleaning is performed every time it is repeated.

  FIG. 8 is a diagram showing the attachment to the car 27 after the guide rail 100 is installed in the hoistway as an application example of the cleaning devices 103a and 103b according to the second embodiment of the present invention. When the normal operation of the elevator is repeated, dust, dirt, and the like adhere to the guide rail 100 due to the raising and lowering of the car 27, so that the riding comfort is lowered. Therefore, as shown in FIG. 8, if the cleaning devices 103a and 103b are attached to the lower side of the car 27 and the object to be cleaned including dust and dirt is removed each time the car 27 is lifted, the riding comfort is always stable. To do. The cleaning devices 103a and 103b are basically required for maintenance work, but application of such a configuration is effective when the use environment of the elevator is easily contaminated with dust or the like.

  During maintenance, there is a concern that the braking distance of the car 27 may increase due to foreign matter being caught between the guide rail 100 and the braking device for stopping the car 27 in an emergency such as rope cutting. Therefore, if the cleaning devices 103a and 103b are attached to the lower side of the car 27 during maintenance work, and the car 27 is operated to rise, the guide surface of the guide rail 100 can be sufficiently cleaned. When the car 27 is lowered, the cleaning effect is slightly reduced. However, if the foreign matter 102 or the like is not firmly fixed, the car 27 can be sufficiently cleaned. Conventionally, the work of manually cleaning a plurality of guide rails 100 from the lowest floor to the highest floor can be cleaned only by the raising and lowering operation of the car 27, so that the time required for maintenance work can be greatly reduced. it can.

  In short, depending on the construction site, when it is not possible to secure a space for placing and cleaning a plurality of guide rails 100 on the floor, the guide rails 100 may need to be installed with a short delivery time due to a destination requirement. In such a case, after the guide rail 100, the car 27, the counterweight, etc. are installed in the hoistway, and the cleaning devices 103a, 103b are attached to the lower side of the car 27, the counterweight, even after the guide rail 100 is installed. Easy to clean.

  In the second embodiment, the cleaning devices 103a and 103b are fixed to the lower side of the car 27 as shown in FIG. At this time, the cleaning devices 103 a and 103 b may be fixed so as to be in close contact with the top surface of the guide rail 100, and a clearance may be provided in the width direction of the guide rail 100. The cleaning devices 103 a and 103 b are fixed to the lower side of the car 27, the opening / closing operation clamp 9 is brought down, and the cleaning devices 103 a and 103 b are fixed to the guide rail 100.

  FIG. 9 is a diagram illustrating an assembly arrangement configuration of the cleaning devices 103a and 103b. 9A is a side view of the whole, FIG. 9B is a diagram in which gears 28a and 28b at the lower part of the tank 13 coupled to the rotation shafts of the side rollers 3a and 3b are exposed, and FIG. 9C. FIG. 3 is a perspective view showing an appearance of a liquid reservoir 29.

  When the cleaning devices 103a and 103b are attached to the lower side of the car 27 and the counterweight, the tank 13 containing the solvent 101 is attached vertically as shown in FIG. Further, gears 28a and 28b disposed in the lower portion of the tank 13 may be attached to the rotation shafts of the side rollers 3a and 3b. FIG. 9B shows a state in which gears 28 a and 28 b are attached to the lower part of the tank 13 as viewed from the top surface side of the guide rail 100.

  In the case of this configuration, when the cleaning devices 103a and 103b move together with the car 27, the side wheels 3a and 3b contacting the side surfaces of the guide rail 100 rotate, and the gears 28a and 28b also rotate. As a result, the solvent 101 in the lower part of the tank 13 can be stably supplied to the side rollers 3a and 3b and the top roller 10 through the hose 24 while stirring.

  Further, when the guide rail 100 is cleaned, the solvent 101 continues to drop onto the side rollers 3a and 3b and the top roller 10, and becomes a mixed liquid of solvent and rust preventive oil. There is a risk of adhesion. Therefore, as a solution, as shown in FIGS. 9A and 9C, a liquid reservoir 29 is provided below the cleaning devices 103a and 103b. Thereby, the solvent 101, the rust preventive oil, and a mixed solution thereof can be collected and prevented from being reattached to the guide rail 100. However, the liquid reservoir 29 needs to be provided so as not to contact the floor (pit) of the hoistway when the car 27 and the counterweight are on the lowest floor.

  In any case, the cleaning device according to the second embodiment is attached to the lower side of the car and the counterweight, so that the cleaning object attached to the guide rail can be efficiently removed simply by raising the car and the counterweight. it can. For this reason, for example, the cleaning time during maintenance work can be significantly shortened. In other words, conventionally, the guide rail after installation has been cleaned manually by an operator on the car, soaking the solvent into the waste cloth manually and lifting the car up and down. Although it took time, this problem can be remarkably improved.

In addition, the rolling member that rolls on both bottom surfaces (non-machined portions) connected to both side surfaces of the guide rail 100 is provided on the distal end side of another support plate attached so as to extend below the support plate 50. A pressing roller 33 provided with a rotating shaft passing therethrough is used. As shown in FIG. 10A, the ball plunger 36 is disposed between the pressing roller 33, the driving rollers 35a and 35b, and the belts 34a and 34b.

  With the drive mechanism having such a configuration, the guide rail 100 is sandwiched, and the rotational force of the rotating shaft of the motor 30 is converted into a force for moving the apparatus main body. When the apparatus is attached to the guide rail 100, the pressing roller 33 on one side and the fixing nut 37 of the driving roller 35a are loosened, and each support plate is spread in the left-right direction of the guide rail 100 and attached to the guide rail 100. Thereafter, the fixing nut 37 may be fastened.

  In FIG. 10A and FIG. 10B, an example in which a cleaning device having a self-propelling function is attached to the guide rail 100 placed on the floor has been described. In this case, by turning on the start switch 32, the rotating shaft of the motor 30 supplied with power from the battery 31 is rotationally driven, and this rotational driving force is transmitted to rotate the driving rollers 35a and 35b.

  Therefore, the apparatus main body and the drive mechanism move along the longitudinal direction of the guide rail 100 from the one end side of the guide rail 100 to the other end side with the side rollers 3a and 3b and the top roller 10 at the head side. However, here, the one end side means one end side of the guide rail 100 close to the operator. The other end side indicates the other end side of the guide rail 100 far from the operator. Along with this, first, the solvent 101 is applied to the guide surface of the guide rail 100 by the side rollers 3 a and 3 b and the top roller 10. Next, the cleaning object is removed by the side scrapers 18a and 18b and the top surface scraper 22, the side surface wipers 19a and 19b, and the top surface wiper 23. While continuing this cleaning operation, the apparatus main body and the drive mechanism eventually move to the other end side.

  Since the reversing switch 38 is provided on the head side of the apparatus main body, if a contact member is installed in the vicinity of the other end side, the mechanism can be switched on when the contact member is contacted. In this case, the rotation direction of the rotation shaft of the motor 30 is reversed, and the motor 30 automatically moves back from the other end side to the one end side. At that time, the cleaning device having a self-propelled function can be collected.

  Furthermore, the present invention can be effectively applied to cleaning when the guide rail 100 is installed before the car 27, the counterweight and the like are installed on the hoistway. For example, the arrangement shown in FIG. 9A may be adopted, and a cleaning device having a self-propelling function on the lowest floor may be attached to the guide rail 100. In this case, by turning on the start switch 32, the rotating shaft of the motor 30 supplied with power from the battery 31 is rotationally driven, and this rotational driving force is transmitted to rotate the driving rollers 35a and 35b.

  Therefore, the apparatus main body rises along the guide rail 100. Along with this, first, the solvent 101 is applied to the guide surface of the guide rail 100 by the side rollers 3 a and 3 b and the top roller 10. Next, the cleaning object is removed by the side scrapers 18a and 18b and the top surface scraper 22, the side surface wipers 19a and 19b, and the top surface wiper 23. While continuing this cleaning operation, the apparatus main body and the drive mechanism eventually move to the top floor.

  After the cleaning device having a self-propelling function has moved to the top floor, the cleaning work may be terminated on the top floor and the cleaning device having the self-propelling function may be collected. However, here too, if the reversing switch 38 is provided on the top side of the apparatus main body, it can be automatically lowered to the lowest floor. In this case, for example, the reversing switch 38 may be switched on when it comes into contact with the top floor wall or a dedicated contact member provided separately. When the reversing switch 38 is switched on, the rotation direction of the rotating shaft of the motor 30 is reversed and automatically descends to the lowest floor. As a result, the cleaning device having a self-propelled function on the lowest floor can be collected.

  Since the cleaning device having a self-propelled function according to the third embodiment can remove the objects to be cleaned from the lowest floor to the highest floor at once, targeting the guide rail after being installed on the hoistway, the cleaning work time Can be greatly reduced. Alternatively, the objects to be cleaned from the top floor to the bottom floor can also be removed. In addition, since the guide rail can be cleaned before attaching the car or counterweight, there is no fear of foreign matter adhering to the shoe of the braking device that operates in the emergency of the elevator, and the emergency braking distance of the elevator can be stabilized. it can. That is, there is a concern that when an operator cleans the guide rail on the car as in the conventional case, the foreign matter that flows out after cleaning adheres to the shoe and the guide rail of the braking device, thereby increasing the braking distance. This problem is solved.

Embodiment 4 FIG.
In the cleaning device according to the fourth embodiment, after the solvent 101 is applied to the guide surface of the guide rail 100, the cleaning brush is applied to the guide rail before removing the object to be cleaned by the scraper and the wiper. The object is scraped out. FIG. 11 is a schematic diagram illustrating a configuration of a main part of the cleaning device according to the fourth embodiment with a part thereof broken.

  Referring to FIG. 11, in the cleaning device according to the fourth embodiment, belts 40a and 40b are bridged between the rotation shafts of the side rollers 3a and 3b and the rotation shafts of the rotary brushes 39a and 39b. . Here, the rotational force of the rotating shafts of the side rollers 3a and 3b is transmitted to the rotary brushes 39a and 39b via the belts 40a and 40b. Accordingly, the rotation direction of the rotary brushes 39a and 39b is reversed so as to be opposite to the rotation direction of the side rollers 3a and 3b along the moving direction of the apparatus indicated by the arrows.

  According to the cleaning device according to the fourth embodiment, the rotary brush can lift a cleaning object such as a foreign object immediately after applying the solvent. As a result, the cleaning effect by the subsequent scraper and wiper is further enhanced, and the guide rail can be cleaned very efficiently.

Embodiment 5 FIG.
In the cleaning apparatus 103 according to the first embodiment, the apparatus structure is simplified by attaching the scraper and the wiper to the same side surface or top surface scraper mounting base. In the cleaning device according to the fifth embodiment, the scraper and the wiper are attached to different mounting bases so that the pressing force of the scraper and the wiper can be adjusted separately.

  According to the cleaning device according to the fifth embodiment, the scraper and the wiper are fixed to separate mounting bases, and the pressing force can be adjusted. Thereby, the pressing force of the scraper can be made stronger than that of the wiper, and the object to be cleaned such as foreign matter adhering to the guide rail can be strongly scraped off. Further, with respect to the wiper, by pressing with a minimum weak force for scraping off the solvent, the rust preventive oil, and a mixture thereof, the wear of the wiper can be reduced and the frequency of replacing the wiper can be reduced.
