FIG. 5 is a top view showing a partially excerpted 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 partially excerpted 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 and 4b are pressed inward toward the guide rail 100 by a constant force by the opposing compression springs 20a and 20b. The lengths of the compression springs 20a and 20b can be adjusted with the adjusting bolts 21a and 21b. Thereby, the pressing force of the side scrapers 18a and 18b can be adjusted. The side scrapers 18a and 18b are preferably metal thin plates having a hardness lower than that of the guide rail 100. The side wipers 19a and 19b may be made of a flexible material such as rubber, other than being made of resin.

Such side scrapers 18a and 18b and 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 device 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 roller 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 dust and solid matter which becomes a stain 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 mounted on the side scraper mounting bases 4a and 4b. For example, when the forces of the compression springs 20a and 20b of the side scraper mounting bases 4a and 4b are 1 kgf, respectively, the spring force of the tension spring 16 may be set to about 3 kgf. With such a setting, the side guide rollers 6a and 6b can be kept in contact with the side surface of the guide rail 100 even when the device is manually operated.

The thickness of the side scrapers 18a and 18b is preferably about 0.2 mm so that the corners always abut on 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 be surely in contact with the side surface of the guide rail 100. It is desirable that the thickness of the side wipers 19a and 19b is also 2 mm or more so that the corners surely abut on the side surface of the guide rail 100. The tips of the side wipers 19a and 19b facing in the direction opposite to the moving direction are also maintained at an acute angle so as to be surely in contact with the side surface of the guide rail 100. Further, in order to suppress a decrease in the amount of rust-preventive oil removed due to wear of the corners of the side wipers 19a and 19b, it is preferable that the pressing force is about 1 kgf. The material of the side wipers 19a and 19b is preferably silicon rubber, urethane rubber or the like having wear resistance.

In any case, the corners of the side wipers 19a and 19b tend to wear by coming into contact with the side surface of the guide rail 100 and sliding, and the amount of rust preventive oil removed tends to decrease. On the other hand, it is considered that the decrease in the amount of rust-preventive oil removed is suppressed because the contact surface that comes into contact with the guide rail 100 is formed by the progress of wear to some extent.

By the way, as shown in FIG. 5, the side scrapers 18a and 18b and the side wipers 19a and 19b first hit the side surface of the convex portion of the guide rail 100. Therefore, it is preferable to attach the side scrapers 18a and 18b to the rear side in the moving direction of the device and the side wipers 19a and 19b to the front side in the moving direction of the device so as to be inclined. .. That is, the side scrapers 18a and 18b can efficiently scrape off the object to be cleaned including the foreign matter 102 adhering to the side surface of the guide rail 100 to the lower side of the guide rail 100. Further, the side wipers 19a and 19b can remove the cleaning object and the solvent remaining on the side surface of the guide rail 100 after the removal treatment by the side scrapers 18a and 18b.

Referring to FIG. 6, a metal top surface scraper 22 and a resin top surface wiper 23 are attached to the top surface scraper mounting base 11. Therefore, the device 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. The object to be cleaned including the rust preventive oil dissolved by the solvent 101 and the foreign matter 102 such as dust and solid matter which becomes a stain is removed by the scraper 22 for the top surface and the wiper 23 for the top surface. The scraper 22 for the top surface is preferably a thin metal plate made of metal having a hardness lower than that of the guide rail 100. The wiper 23 for the top surface may be made of a flexible material such as rubber, other than being made of resin.

As for the top surface scraper 22, the pressing force may be controlled by a spring as in the case of the side surface scrapers 18a and 18b, but in general, the top surface of the guide rail 100 has a lower surface roughness than the side surface. .. Therefore, the protrusion of the side scrapers 18a and 18b and the side wipers 19a and 19b may be adjusted to be about 1 mm with respect to the lower surface of the top surface scraper mounting base 11. The tip of the top scraper 22 pointing in the moving direction indicated by the arrow is maintained at an acute angle so as to be surely in contact with the side surface of the guide rail 100. The tip of the top wiper 23 facing in the direction opposite to the moving direction is also maintained at an acute angle so as to be surely in contact with the side surface of the guide rail 100.

The scraper 22 for the top surface has a contact portion at the tip arranged on the front side in the moving direction of the device, and if the extending portion is attached to the rear side in the moving direction of the device so as to be slanted, the scraped foreign matter 102 or the like can be removed. The object to be cleaned can be flushed to the side surface of the guide rail 100. After that, the object to be cleaned can be dropped to the lower side of the guide rail 100 by the side scrapers 18a and 18b on the side surface of the guide rail 100. As for the top surface wiper 23, the tip end portion may first hit the top surface of the guide rail 100, and the extending portion may be attached so as to be slanted on the front side in the moving direction of the device. In the cleaning device 103 according to the first embodiment, the scraper mounting base 11 for the top surface can be brought into contact with the top surface of the guide rail 100 for cleaning in a fixed position.

FIG. 7 is a side view showing the supply mechanism of the solvent 101 in the cleaning device 103 with a partial break.

Referring to FIG. 7, the tank 13 for storing the solvent 101 supplies the solvent 101 to the side roller 3a and 3b and the top roller 10 through the on-off valve 25. Therefore, the on-off valve 25 is provided near the top surface of the convex portion of the guide rail 100. Further, the hose 24 as a supply pipe coupled to the on-off valve is arranged at a position where the solvent 101 can be supplied to the surface of the side roller 3a and 3b and the top roller 10 at the tip portion thereof. .. As the solvent 101, a case where an organic solvent is used can be exemplified. The materials of the side roller 3a and 3b and the top roller 10 may be any material having 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 is released by the compression spring 26 contracting by pressing the main body of the apparatus against the guide rail 100, and 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. Will be supplied. Further, when the main body of the on-off valve 25 is removed from the guide rail 100, the compression spring 26 is extended and closed, and the supply of the solvent 101 is cut off.

Before installing the elevator, the cleaning device 103 having such a configuration has a plurality of guide rails 100 laid on the floor so that the top surface faces up, and the opening / closing operation clamp 9 is raised to raise the fixed side base plate 1 and the fixed side base plate 1. The distance between the movable base plates 2 is widened. Then, after mounting the device main body on the guide rail 100, the opening / closing operation clamp 9 is tilted down, the guide rail 100 is sandwiched by the side guide rollers 6a and 6b by the spring force of the tension spring 16, and the device main body is held against 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 attached to the side surface 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 roller 3a and 3b 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 roller 3a and 3b and the top roller 10 on the leading side. At this time, the solvent 101 is applied to the guide surface of the guide rail 100, and the object to be cleaned containing the rust preventive oil adhering to the guide rail 100 and the foreign matter 102 such as dust and solid matter which becomes dirt is dissolved by the solvent 101. After that, the side scrapers 18a and 18b and the top scraper 22 scrape off the object to be cleaned including the melted foreign matter 102. Further, the side wipers 19a and 19b and the top wiper 23 wipe off the solvent 101 remaining on the guide surface of the guide rail 100 and the object to be cleaned. As a result, the object to be cleaned is removed from the guide surface of the guide rail 100.

That is, according to the cleaning device according to the first embodiment, the rollers, scrapers, and wipers for which the solvent is applied are arranged in order and attached to the base member. By moving the main body of the device toward the leading side of the roller in the longitudinal direction of the guide rail, the object to be cleaned adhering to the guide surface is cleaned. At this time, the roller applies the supplied solvent to the guide surface, the scraper scrapes off the object to be cleaned including the rust preventive oil and the foreign matter 102, and the wiper is the residual solvent 101 and the object to be cleaned. To get rid of. Therefore, it has a remarkable effect that the guide surface of the guide rail can be cleaned more stably and efficiently than before.

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

Embodiment 2.
The cleaning device 103 according to the first embodiment has described a case where the guide rail 100 in a floor-standing state before being installed in the hoistway of an elevator 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 attachment to the car 27 after the guide rail 100 is installed on 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 and dirt 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 cleaning devices 103a and 103b are attached to the lower side of the car 27 and the cleaning object including dust and dirt is removed each time the car 27 rises, the riding comfort is always stable. do. The cleaning devices 103a and 103b are basically required for maintenance work, but when the usage environment of the elevator is easily contaminated with dust or the like, the application of such a configuration is effective.

During maintenance, there is a concern that the braking distance of the car 27 may increase due to foreign matter being caught between the braking device for stopping the car 27 and the guide rail 100 in an emergency such as when the rope is cut. 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 raised, the guide surface of the guide rail 100 can be sufficiently cleaned. When the car 27 is in the descending operation, the cleaning effect is slightly reduced, but if the foreign matter 102 or the like is not firmly fixed, the car can be sufficiently cleaned. In the past, the work of manually cleaning a plurality of guide rails 100 from the bottom floor to the top floor can be cleaned only by raising and lowering the car 27, so that the time required for maintenance work can be significantly reduced. can.

In short, depending on the construction site, if it is not possible to secure a space for cleaning by placing a plurality of guide rails 100 on the floor, it may be necessary to install the guide rails 100 in a short delivery time due to a request for going out. In such a case, if the guide rail 100, the car 27, the counterweight, etc. are installed on the hoistway, and then the cleaning devices 103a, 103b are attached to the underside of the car 27, the counterweight, the guide rail 100 can be installed even after the guide rail 100 is installed. , Can be easily cleaned.

In the second embodiment, the cleaning devices 103a and 103b are fixed to the lower side of the car 27 as shown in FIG. 8 with the opening / closing operation clamp 9 raised. At this time, the cleaning devices 103a and 103b 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 103a and 103b are fixed to the lower side of the car 27, the opening / closing operation clamp 9 is tilted down, and the cleaning devices 103a and 103b are fixed to the guide rail 100.

FIG. 9 is a diagram illustrating an assembly arrangement configuration of the cleaning devices 103a and 103b. 9 (a) is an overall side view, FIG. 9 (b) is a view showing the gears 28a and 28b at the lower part of the tank 13 coupled to the rotating shafts of the side rollers 3a and 3b, and FIG. 9 (c). Is a perspective view showing the appearance of the 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. 9A. Further, gears 28a and 28b arranged in the lower part of the tank 13 may be attached to the rotating shafts of the side rollers 3a and 3b. FIG. 9B shows how the gears 28a and 28b are attached to the lower part of the tank 13 as seen from the top surface side of the guide rail 100.

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

Further, when cleaning the guide rail 100, the solvent 101 continues to drip onto the side rollers 3a and 3b and the top roller 10, becomes a mixed liquid of the solvent and the rust preventive oil, and continues to fall to the guide rail 100 again. There is a risk of adhesion. Therefore, as a solution to this problem, as shown in FIGS. 9 (a) and 9 (c), a liquid reservoir 29 is provided under the cleaning devices 103a and 103b. As a result, the solvent 101, the rust preventive oil, and the mixture thereof can be recovered and prevented from being reattached to the guide rail 100. However, the liquid reservoir 29 needs to be provided so as not to come into contact with the floor surface (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 balance weight, so that the cleaning target attached to the guide rail can be efficiently removed only by raising the car and the balance weight. can. Therefore, for example, the cleaning time during maintenance work can be significantly shortened. That is, in the past, cleaning of the guide rail after installation was considerable because a worker rides on the car, manually soaks the solvent into the waste cloth, etc., and manually raises and lowers the car. It took a long time, but the problem can be remarkably improved.

Embodiment 3.
The cleaning device according to the third embodiment is provided with a drive mechanism that allows the main body of the device to self-propell along the longitudinal direction of the guide rail 100. 10A and 10B are views showing a schematic configuration of a cleaning device having a self-propelled function according to the third embodiment of the present invention, where FIG. 10A is a side view and FIG. 10B is an end view.

Of these, the motor 30 attached to the upper surface of the support plate 50 rotationally drives the rotating shaft. The battery 31 provided adjacent to the motor 30 on the upper surface of the support plate 50 is a storage battery that supplies power to the motor 30. The start switch 32 provided on the battery 31 activates the battery 31. The reversing switch 38 arranged on the tank 13 side away from the support plate 50 reverses the rotation axis of the motor 30.

The driving mechanism unit transfers the rotational force of the rotating shaft of the motor 30 to the drive shaft of the driven roller R and the drive shafts of the drive rollers 35a and 35b below the support plate 50 via the belts 34a and 34b. , Is transmitted to the drive rollers 35a and 35b. As a result, the main body of the device can be self-propelled. As shown in FIG. 10B, the drive rollers 35a and 35b are provided with the drive shaft penetrating the tip end side of the support plate attached so as to extend below the support plate 50, and the guide rail 100 is provided. It is abutted so as to sandwich the concave portion formed below both side surfaces of the convex portion of the above. A fixing nut 37 for preventing the belt from coming off is provided on the outer side of the belt 34a spanning the drive shaft of the drive roller 35a.

The driven mechanism unit includes a rolling member that rolls with respect to both bottom surfaces connected to the top surface and both side surfaces of the convex portion of the guide rail 100 in response to the movement of the device main body by the driving mechanism unit. A pair of ball plungers 36 arranged at intervals from each other are used for the rolling member that rolls on the top surface of the convex portion of the guide rail 100. Further, the rolling member that rolls on both bottom surfaces (non-machined portions) connected to both side surfaces of the guide rail 100 is on the tip end side of another support plate attached so as to extend below the support plate 50. A pressing roller 33 provided so as to penetrate the rotating shaft is used. As shown in FIG. 10A, the ball plunger 36 is arranged 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 main body of the apparatus. When attaching the device to the guide rail 100, the pressing roller 33 on one side and the fixing nut 37 of the drive roller 35a were loosened, and each support plate was spread in the left-right direction of the guide rail 100 and attached to the guide rail 100. After that, the fixing nut 37 may be fastened.

In FIGS. 10 (a) and 10 (b), an example in which a cleaning device having a self-propelled function is attached to the guide rail 100 in a floor-standing state has been described. In this case, by turning on the start switch 32, the rotation 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 drive rollers 35a and 35b.

Therefore, the apparatus main body and the drive mechanism move along the longitudinal direction of the guide rail 100 from one end side to the other end side of the guide rail 100 with the side roller 3a and 3b and the top roller 10 on the front side. However, here, the one end side means the one end side of the guide rail 100 close to the operator. The other end side shall indicate 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 roller 3a and 3b and the top roller 10. Next, the objects to be cleaned are removed by the side scrapers 18a and 18b and the top scraper 22 and the side wipers 19a and 19b and the top wiper 23. While continuing this cleaning operation, the main body of the device and the drive mechanism eventually move to the other end side.

Since the reversing switch 38 is provided on the front side of the main body of the apparatus, if a contact member is installed near the other end side, the switch can be turned on when the contact member comes into contact with the contact member. In this case, the rotation direction of the rotation shaft of the motor 30 is reversed, and the motor 30 automatically returns and moves from the other end side to the one end side. At that point, the self-propelled cleaning device can be recovered.

Further, it can be effectively applied to cleaning when the guide rail 100 is installed before the car 27, the counterweight, etc. are installed on the hoistway. For example, the arrangement configuration shown in FIG. 9A may be adopted, and a cleaning device having a self-propelled function on the lowest floor may be attached to the guide rail 100. In this case, by turning on the start switch 32, the rotation 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 drive rollers 35a and 35b.

Therefore, the device 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 roller 3a and 3b and the top roller 10. Next, the objects to be cleaned are removed by the side scrapers 18a and 18b and the top scraper 22 and the side wipers 19a and 19b and the top wiper 23. While continuing this cleaning operation, the main body of the device and the drive mechanism eventually move to the top floor.

After the self-propelled cleaning device has moved to the top floor, the cleaning work may be completed on the top floor and the self-propelled cleaning device may be collected. However, even here, if the reversing switch 38 is provided on the front side of the main body of the apparatus, 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 a wall on the top floor, a dedicated contact member provided separately, or the like. When the reversing switch 38 is switched on, the rotation direction of the rotation shaft of the motor 30 is reversed, and the motor 30 automatically descends to the lowest floor. As a result, the cleaning device having a self-propelled function can be collected on the lowest floor.

The cleaning device having a self-propelled function according to the third embodiment can remove the object to be cleaned from the bottom floor to the top floor at once for the guide rail after being installed on the hoistway, so that the cleaning work time Can be significantly reduced. Alternatively, the object to be cleaned from the top floor to the bottom floor can also be removed. In addition, since the guide rails can be cleaned before installing the car and balance weight, there is no concern that foreign matter will adhere to the shoes of the braking device that operates in an emergency of the elevator, and the braking distance of the elevator in an emergency can be stabilized. can. That is, there is a concern that when a worker cleans the guide rail on the car as in the conventional case, foreign matter flowing out after cleaning adheres to the shoe and the guide rail of the braking device, and the braking distance increases. , This problem is solved.

Embodiment 4.
The cleaning device according to the fourth embodiment applies a rotary brush to the guide rail for cleaning after applying the solvent 101 to the guide surface of the guide rail 100 and before removing the object to be cleaned by the scraper and the wiper.

Referring to FIG. 11, in the cleaning device according to the fourth embodiment, the belts 40a and 40b are bridged between the rotating shafts of the side rollers 3a and 3b and the rotating 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. As a result, the rotation directions of the rotary brushes 39a and 39b are reversed so as to be opposite to the rotation directions of the side roller 3a and 3b along the movement direction of the device indicated by the arrow.

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

Embodiment 5.
In the cleaning device 103 according to the first embodiment, the device structure is simplified by attaching the scraper and the wiper to the scraper mounting base for the same side surface or the top surface. In the cleaning device according to the fifth embodiment, the scraper and the wiper are attached to separate 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 different mounting bases, and the pressing force of each can be adjusted. As a result, 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 firmly scraped off. Further, the wiper can be pressed with the minimum weak force for scraping off the solvent, the rust preventive oil, and the mixture thereof, so that the wear of the wiper can be reduced and the frequency of replacing the wiper can be reduced.
