Description

The present invention relates to a method for repairing a passenger conveyor and a repair device for a moving handrail.

Passenger conveyors such as escalators and moving walkways are equipped with steps and moving handrails. The steps and handrail move at the same speed and in the same direction. The movable handrail includes a handrail main body having a horseshoe shape (substantially C-shape) in cross section, and a canvas covering the inner surface of the handrail main body. The moving handrail is wound around the drive pulley and moves as the drive pulley rotates. Further, the movable handrail is attached to a handrail guide and moves along the handrail guide.

When the passenger conveyor is in operation, the moving handrail moves in circulation due to the frictional force generated at the contact portion between the drive pulley and the moving handrail. Therefore, as the period of use of the passenger conveyor increases, the canvas that contacts the drive pulley and handrail guide gradually wears out. When the canvas wear progresses and a part of the canvas wears off, the inner surface of the handrail body becomes exposed. The inner surface of the handrail body is made of a high friction material such as urethane rubber. Therefore, if the inner surface of the handrail body comes into direct contact with the drive pulley or handrail guide due to wear of the canvas, abnormal noise is likely to be generated due to friction between the handrail body and the handrail guide.

Patent Document 1 describes a technique for repairing a canvas peeling portion by filling an adhesive in a portion where the canvas peels off due to wear (hereinafter referred to as a “canvas peeling portion”).

Japanese Patent Application Publication No. 10-250969

However, since the technique described in Patent Document 1 is a repair method that simply fills the canvas peeling part with adhesive, when the passenger conveyor is restarted after repair, the adhesive filled in the canvas peeling part will be removed. It will come into direct contact with handrail guides, etc. Therefore, when the frictional force of the adhesive is high, the adhesive rubs against the handrail guide, which tends to cause abnormal noise.

An object of the present invention is to provide a technique that can suppress the generation of abnormal noise after repair when repairing a damaged portion of canvas in a moving handrail.

In order to solve the above problems, for example, the configurations described in the claims are adopted.
The present application includes a plurality of means for solving the above-mentioned problems, and one of them is a method for repairing a passenger conveyor equipped with a moving handrail having canvas, in which the damaged part of the canvas in the moving handrail is repaired in a concave shape. It has a cutting process.

According to the present invention, when repairing a damaged part of the canvas in a moving handrail, it is possible to suppress the occurrence of abnormal noise after the repair.
Problems, configurations, and effects other than those described above will be made clear by the description of the embodiments below.

Embodiments of the present invention will be described in detail below with reference to the drawings. In this specification and the drawings, elements having substantially the same functions or configurations are denoted by the same reference numerals, and redundant explanations are omitted.

FIG. 1 is a schematic side view showing the configuration of an escalator according to this embodiment.
As shown in FIG. 1, the escalator 1 includes a plurality of steps 2 connected in an endless manner, balustrades 3 arranged on the left and right sides of the steps 2, and a movable handrail 4 that moves on the balustrades 3. The steps 2 and the handrail 4 move in the same direction and at the same speed. In addition, in this embodiment, although an escalator is mentioned as an example of a passenger conveyor, a passenger conveyor is not limited to an escalator, and may be a moving walkway, etc., for example.

As shown in FIG. 2, the movable handrail 4 is detachably attached to a handrail guide 5. The handrail guide 5 is provided at the upper end of the balustrade 3. The handrail guide 5 guides the movement of the movable handrail 4. The movable handrail 4 is configured so as not to come off the handrail guide 5 while moving along the handrail guide 5. A parapet lighting 6 is arranged below the handrail guide 5.

As shown in FIG. 3, the movable handrail 4 includes a handrail main body 40 having a horseshoe-shaped (substantially C-shaped) cross section, and a canvas 10 that covers the inner surface of the handrail main body 40. The handrail body 40 includes an outer decorative resin part 7, a core material 8 formed inside the decorative resin part 7, and a plurality of steel cords 9 embedded inside the core material 8. The decorative resin portion 7 is formed to cover the outer surface of the core material 8. The core material 8 is formed of, for example, a rubber material. The inner surface of the core material 8 is covered with a canvas 10. The steel cord 9 is a tensile member for ensuring the tensile strength of the moving handrail 4. The tensile body is not limited to the steel cord 9, but may be composed of, for example, a steel tape.

The canvas 10 is a sliding material that serves to reduce the frictional force between the movable handrail 4 and the handrail guide 5 when the movable handrail 4 moves along the handrail guide 5. The canvas 10 is integrally formed with the decorative resin part 7 and the core material 8.

The movable handrail 4 configured as described above is wound around a drive pulley (not shown) included in the escalator 1. The movable handrail 4 circulates according to the rotation of the drive pulley due to the frictional force with the drive pulley. At this time, the canvas 10 of the movable handrail 4 moves while contacting the drive pulley and the handrail guide 5. Therefore, when the escalator 1 is used for a long period of time, the surface of the canvas 10 that comes into contact with the drive pulley and the handrail guide 5 wears out. As wear of the canvas 10 progresses and the canvas 10 peels off or wears out, the underlying core material 8 is exposed. The core material 8 has higher frictional resistance than the canvas 10. Therefore, during the circulation movement of the handrail 4, the core material 8 exposed due to wear of the canvas 10 rubs against the drive pulley and the handrail guide 5, which tends to generate abnormal noise. Therefore, in this embodiment, the escalator 1 is repaired by the following method.

FIG. 4 is a flowchart showing the escalator repair method according to this embodiment.
In the following description, a portion of the canvas 10 that has peeled off or frayed due to wear or the like will be collectively referred to as a damaged portion of the canvas 10. However, in this embodiment, it does not matter what causes the damage to the canvas 10. Further, as shown in FIG. 3, the damaged portion 12 of the canvas 10 of the movable handrail 4 is likely to occur on the inside of the ear portion 11 of the movable handrail 4 (particularly the lower rounded portion). The ears 11 are a part of the movable handrail 4 and are formed on both sides of the movable handrail 4 in the width direction X. Further, the ear portion 11 is formed to have a horizontal U-shape in cross section. The escalator repair method according to the present embodiment is a method suitable for repairing the damaged portion 12 of the canvas 10 that has occurred on the ear portion 11 of the moving handrail 4.

First, the worker in charge of the repair work on the escalator 1 visually confirms the position of the damaged part 12 of the canvas 10, and then turns on and off the power of the escalator 1 to find the position of the canvas 10 suitable for the repair work. The damaged part 12 is moved to (step S1). A suitable position for repair work is a position where it is easy to turn over the handrail 4, and specifically, as shown in Figure 1, the position is in the middle of the straight part of the escalator 1 (position P in the figure or a position close to this). be.

Next, the operator determines whether the repair can be performed without removing the movable handrail 4 from the handrail guide 5 (step S2). At this time, the worker loosens the tension on the movable handrail 4 so that the inside of the movable handrail 4 can be easily checked visually. If the operator determines that the repair cannot be performed without removing the movable handrail 4 from the handrail guide 5, the worker removes the movable handrail 4 from the handrail guide 5 (step S3). Whether or not it is necessary to remove the movable handrail 4 from the handrail guide 5 may be determined using the size of the damaged portion 12 of the canvas 10 as a guide.

Subsequently, the operator measures the size and depth of the damaged portion 12 of the canvas 10 shown in FIG. 5 (step S4). This measurement may be performed using, for example, a ruler or a depth measuring gauge. The size of the damaged part 12 is defined by the length of the damaged part 12 in the longitudinal direction of the moving handrail 4.

Next, the operator checks whether the depth of the damaged part 12 is smaller than the thickness of the repaired canvas 13 (FIG. 6) (step S5). Here, if the depth of the damaged part 12 is smaller than the thickness of the repaired canvas 13 and the repaired canvas 13 is simply glued to the damaged part 12, as shown in FIG. protrudes from the surface 10a of the existing canvas 10. Therefore, when the movable handrail 4 is circulated after repair, the peripheral edge 14 of the repaired canvas 13 comes into contact with the handrail guide 5 and the drive pulley, making the repaired canvas 13 easy to peel off.

Therefore, if the depth of the damaged part 12 is smaller than the thickness of the repaired canvas 13, as shown in FIG. 7, the damaged part 12 of the canvas 10 is shaved into a concave shape by a predetermined cutting margin 15 (step S6). In this specification, "shaving the damaged part 12 into a concave shape" means cutting the damaged part 12 into a concave shape so that the surface 12b of the damaged part 12 after being scraped is in a concave state compared to the surface 12a of the damaged part 12 before being scraped. It means to remove. Therefore, the thickness of the movable handrail 4 becomes smaller by the amount of the cutting margin 15 at the location where the damaged portion 12 is cut. In step S6, the operator cuts the damaged part 12 so that the depth of the damaged part 12 is equal to or slightly deeper than the thickness of the repaired canvas 13. That is, the operator cuts the damaged part 12 so that the depth of the damaged part 12 is equal to or less than the thickness of the repaired canvas 13. Possible methods for scraping the damaged portion 12 include, for example, a method using sandpaper or a method using a hand grinder.

When the damaged portion 12 is shaved in this manner, the thickness of the movable handrail 4 (core material 8) at the damaged portion 12 of the canvas 10 is reduced by the amount of the scraping margin 15. The predetermined cutting margin 15 is such that when the repaired canvas 13 is adhered to the damaged part 12 of the canvas 10 in step S9 described later, as shown in FIG. 8, the repaired canvas 13 does not protrude from the surface 10a of the existing canvas 10. The dimensions are approximately.

After that, the operator cleans the damaged portion 12 cut in step S6 (step S7). The work of cleaning the damaged part 12 includes the work of cutting off the canvas 10 that has peeled off or frayed due to wear, the work of removing the shavings of the core material 8, and the work of cleaning the damaged part 12 after being scraped with a degreasing spray or the like. At least one of these tasks is included.

Next, the operator cuts out the repaired canvas 13 one size smaller than the size of the damaged part 12 (step S8). At this time, the operator cuts out the repair canvas 13 according to the planar shape of the damaged part 12. The operator also cuts out the repaired canvas 13 to a size smaller than the damaged part 12 by, for example, several millimeters so that the peripheral edge 14 (FIG. 8) of the repaired canvas 13 does not protrude from the surface of the existing canvas 10.

Next, as shown in FIG. 8, the worker applies adhesive to one side of the repaired canvas 13 cut out in step S8, and presses this coated surface against the damaged area 12 to attach the repaired canvas 13 to the damaged area. 12 (step S9). As the adhesive, for example, liquid, gel, gel, cream, or spray adhesives can be used. By bonding the repaired canvas 13 with adhesive in this manner, when the repaired canvas 13 is pressed against the damaged area 12 as described above, the adhesive spreads and blends over the entire applied surface of the repaired canvas 13. Therefore, a good adhesive state can be obtained between the repaired canvas 13 and the damaged part 12.

Next, the operator presses the repaired canvas 13 adhered as described above until a predetermined hardening time (step S10). For example, if the predetermined curing time is 5 minutes, the operator maintains the state in which the repaired canvas 13 is pressed against the damaged area 12 for 5 minutes. Thereby, the repaired canvas 13 can be adhered to the damaged part 12 in close contact with it. The curing time may be appropriately set depending on the adhesive used to bond the repaired canvas 13.

Finally, the operator returns the movable handrail 4 to its original state (step S11). For example, when the operator removes the movable handrail 4 from the handrail guide 5 in step S3, the operator applies a predetermined tension to the movable handrail 4 after attaching the movable handrail 4 to the handrail guide 5. Further, when the worker performs repair work without removing the movable handrail 4 from the handrail guide 5, the worker applies a predetermined tension to the movable handrail 4.
The above is a repair method when the canvas 10 of the moving handrail 4 in the escalator 1 is damaged.

The escalator repair method according to the present embodiment includes a step of cutting the damaged part 12 of the canvas 10 into a concave shape when repairing the damaged part 12 that has occurred in the canvas 10 of the moving handrail 4. Thereby, when the escalator 1 is restarted after repairing the damaged portion 12, it is possible to suppress the repaired portion of the damaged portion 12 from coming into contact with the handrail guide 5 or the like. Therefore, it is possible to suppress the occurrence of abnormal noise after repair.

Furthermore, the escalator repair method according to the present embodiment includes a step of adhering a repair canvas 13 to the damaged part 12 of the canvas 10 that has been shaved into a concave shape. As a result, the damaged part 12 of the canvas 10 is covered by the repaired canvas 13, so that the damaged part 12 can be protected by the repaired canvas 13 and the frictional force of the repaired part can be kept low.

Furthermore, in the escalator repair method according to the present embodiment, when the repair canvas 13 is bonded to the damaged part 12 of the canvas 10 in step S9, the repair canvas 13 is prevented from protruding from the surface 10a of the existing canvas 10 in step S6. The damaged part 12 is scraped. Thereby, it is possible to suppress the repaired canvas 13 adhered to the damaged portion 12 of the canvas 10 from coming into contact with the handrail guide 5 or the like.

Furthermore, in the escalator repair method according to the present embodiment, a repair canvas 13 that is one size smaller than the damaged portion 12 of the canvas 10 is used. Thereby, when the repair canvas 13 is adhered to the damaged part 12, it is possible to suppress the repair canvas 13 from protruding from the damaged part 12.

Further, in the escalator repair method according to the present embodiment, the damaged portion 12 is shaved so that the depth of the damaged portion 12 is equal to or less than the thickness of the repair canvas 13. As a result, as shown in FIG. 8, when the repaired canvas 13 is bonded to the damaged area 12, the surface 13a of the repaired canvas 13 is flush with the surface 10a of the existing canvas 10 or is concave than the surface 10a of the existing canvas 10. It can be placed separately. Therefore, it is possible to prevent the repaired canvas 13 adhered to the damaged portion 12 of the canvas 10 from coming into contact with the handrail guide 5 or the like.

Note that in the above embodiment, a method of bonding the repair canvas 13 to the damaged portion 12 using an adhesive is adopted, but the method of bonding the repair canvas 13 is not limited to this.
For example, the repaired canvas 13 may be adhered using an adhesive tape that matches the size of the repaired canvas 13. The adhesive tape used is adhesive tape on both sides. In this method, a predetermined adhesive force can be obtained simply by pressing the repaired canvas 13 onto the damaged area 12 with an adhesive tape, so that curing time and the like are not required. Therefore, repair work on the moving handrail 4 can be performed efficiently. Another advantage is that workers' hands are less likely to get dirty.

Furthermore, the repair canvas 13 may be bonded to the damaged portion 12 by thermal welding. Specifically, heat is applied to the repair canvas 13 placed over the damaged area 12 to thermally weld the repair canvas 13 to the core material 8 that is the base of the damaged area 12 . According to this method, high adhesive strength can be obtained between the damaged part 12 and the repaired canvas 13.

Further, in the above embodiment, the damaged part 12 is scraped in step S6, and then the repair canvas 13 is glued to the damaged part 12 in step S9, but the invention is not limited to this. You don't have to. That is, after the damaged part 12 is scraped off, the damaged part 12 may be left exposed. In that case, the damaged part 12 may be cut deeply so that the core material 8 forming the surface of the damaged part 12 does not come into contact with the handrail guide 5 or the drive pulley. In this way, when the damaged part 12 is not covered with anything after the damaged part 12 is scraped, the steps (S8 to S10) for adhering the repair canvas 13 to the damaged part 12 can be omitted. Therefore, the time required for repairing the moving handrail 4 can be significantly reduced.

Moreover, after the damaged part 12 is scraped in step S6, it is preferable to clean the damaged part 12 in step S7. Thereby, the repaired canvas 13 can be bonded to the damaged section 12 without interposing shavings or the like between the damaged section 12 and the repaired canvas 13. Therefore, a good adhesion state can be obtained.

Next, a movable handrail repair instrument (hereinafter also simply referred to as a "repair instrument") according to the present embodiment will be described.
The repair instrument according to this embodiment is suitable for use in carrying out the escalator repair method described above. However, the movable handrail repair device according to this embodiment can also be used when performing methods other than the escalator repair method described above. Moreover, the maintenance tool according to this embodiment is used when a damaged part 12 occurs inside the ear part 11 of the moving handrail 4, as shown in FIG. The inside of the ear portion 11 is narrow. For this reason, it is difficult to bring the repaired canvas 13 into close contact with the damaged area 12. In such cases, it is preferable to use the repair tools described below.

FIG. 9 is a perspective view showing a configuration example of a moving handrail repair instrument according to the present embodiment.
As shown in FIG. 9, the movable handrail repair tool 100 includes a pair of holding parts 101 and a movement adjustment part 102 that connects the pair of holding parts 101.

The pair of pressing parts 101 are each formed into a rod shape. The pair of pressing parts 101 are arranged parallel to and facing each other. Each holding portion 101 is formed to have a D-shaped cross section so as to be the same as the shape of the ear portion 11 or one size larger than the ear portion 11 . Further, each pressing portion 101 has a pressing surface 101a for pressing the inner surface of the ear portion 11. The pressing surface 101a is formed to have a horizontal U-shape in cross section so as to follow the shape of the lug 11 of the moving handrail 4.

The movement adjustment section 102 is a member that can move the pair of pressing sections 101 toward or away from each other. The movement adjustment section 102 is configured by, for example, a turnbuckle. As shown in FIG. 10, the movement adjustment section 102 includes a rotatable operation section 102a and a pair of extension/contraction sections 102b. The pair of extensible parts 102b expands and contracts in the direction of the arrow in FIG. 10 by rotating the operating part 102a. Specifically, when the operating section 102a is rotated in one direction, the pair of extensible sections 102b extend, and when the operating section 102a is rotated in the opposite direction, the pair of extensible sections 102b are contracted.

Next, a procedure for repairing the movable handrail 4 using the repair tool 100 according to the present embodiment will be described. Here, as an example, as shown in FIG. 3, a repair method when a damaged portion 12 exists in the ear portion 11 of the handrail body 40 will be described.

First, steps S1 to S9 are performed according to the flowchart shown in FIG.
Next, the repair tool 100 is used to perform the work in step S10. The work in step S10 is performed in the following steps.

First, the operator inserts the repair tool 100 into the movable handrail 4, as shown in FIG.
Next, as shown in FIG. 11, the operator rotates the movement adjusting section 102 of the repair tool 100 to move the pair of pressers 101 along with the corresponding telescopic sections 102b in the width direction X of the movable handrail 4. Stretch it to. At this time, the operator presses the pressing surfaces 101a of the pair of pressing parts 101 against the inside (inner surface) of the corresponding ear part 11 by rotating the movement adjustment part 102 with an appropriate force. As a result, the repair canvas 13 adhered to the damaged part 12 of the ear part 11 is pressed by the pressing part 101.

Thereafter, after pressing the repaired canvas 13 until a predetermined hardening time, the operator rotates the movement adjusting section 102 in the opposite direction to the previous direction, so that the pressing surface 101a of the pair of pressing sections 101 is pressed against the corresponding ear. spaced from the inside of the section 11. Further, the operator rotates the movement adjustment section 102 by a predetermined amount to retract the repair instrument 100, and then removes the repair instrument 100 from the movable handrail 4.

In the present embodiment, the pair of holding parts 101 are made of a material (for example, ultra-high molecular weight polyethylene) that is non-adhesive to the adhesive used for adhering the repaired canvas 13. As a result, even when the adhesive is cured while the repair canvas 13 is pressed by the pair of pressers 101, the presser portions 101 are prevented from sticking to the ears 11, and the repair tool 100 can be easily removed from the movable handrail 4. Can be removed.

As described above, by repairing the moving handrail 4 using the repair tool 100, even if the damaged part 12 occurs inside the ear part 11, the repair canvas 13 can be reliably brought into close contact with the damaged part 12. can. Therefore, the damaged portion 12 caused in the ear portion 11 can be easily repaired. In addition, if the size (length) of the damaged part 12 in the longitudinal direction of the moving handrail 4 is larger than the longitudinal dimension of the holding part 201 of the repair instrument 100, a plurality of repair instruments 100 may be used.

By the way, when repairing the damaged part 12 (see FIG. 3) that has occurred in the ear part 11 of the moving handrail 4 using the above-mentioned repair tool 100, depending on the pasting state and position of the repair canvas 13, the movement adjusting part 102 may be damaged. When the pair of presser parts 101 are extended by rotating, there is a risk that the presser parts 101 will drag the repaired canvas 13 and the repaired canvas 13 will be displaced. In such cases, it is preferable to use the repair tools described below.

FIG. 12 is a perspective view showing another configuration example of the movable handrail repair instrument according to the present embodiment.
As shown in FIG. 12, the movable handrail repair tool 200 includes a pair of holding parts 201, a movement adjusting part 202 that connects the pair of holding parts 201, and a plurality of (four in this example) elastic bodies 203. We are prepared. The configuration of the pair of pressing parts 201 is similar to the configuration of the pair of pressing parts 101 described above, and the configuration of the movement adjustment part 202 is similar to the configuration of the movement adjustment part 102 described above.

Each elastic body 203 is constituted by a leaf spring. A leaf spring is preferable because it has a simple structure, is easy to elastically deform, and has low frictional resistance with the existing canvas 10. However, the elastic body 203 is not limited to a leaf spring. Each elastic body 203 is attached to one side 201b of the holding portion 201 by screwing. Each elastic body 203 has an elastic force Sp in the thickness direction Z of the holding portion 201, as shown in FIG.

When repairing the movable handrail 4 using the repair instrument 200 configured as described above, the operator inserts the repair instrument 200 into the movable handrail 4 with the pair of pressers 201 retracted. Next, the operator compresses each elastic body 203 by pressing one side 201b of the pair of pressers 201 against the inside of the moving handrail 4.

Next, the operator expands the pair of pressers 201 in the width direction X of the movable handrail 4 by rotating the movement adjusting section 202 with each elastic body 203 compressed. At this time, the pressing surfaces 201a of the pair of pressing parts 201 are maintained apart from the repaired canvas 13.

Thereafter, the operator extends the pair of pressers 201 to a position where the pressing surfaces 201a of the pair of pressers 201 come into contact with the insides of the ears 11. Next, the operator releases the compression of each elastic body 203 by releasing the pressing of the pair of pressers 201. As a result, each elastic body 203 presses the pair of pressing portions 201 toward one side (downward in FIG. 14) of the movable handrail 4 in the thickness direction Z, as shown in FIG. As a result, the repaired canvas 13 is pressed by the pressing portion 201.

By repairing the movable handrail 4 using the repair tool 200 in this way, when the damaged part 12 occurs inside the ear part 11, the repaired canvas 13 can be placed on the damaged part 12 without shifting the position of the repaired canvas 13. can be imposed.

Note that the present invention is not limited to the embodiments described above, and includes various modifications. For example, in the embodiments described above, the present invention is described in detail to make it easier to understand, but the present invention is not necessarily limited to having all the configurations described in the embodiments described above. Further, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment. Furthermore, it is also possible to add the configuration of another embodiment to the configuration of one embodiment. It is also possible to delete some of the configurations of each embodiment, add other configurations, or replace them with other configurations.
