In a passenger conveyor having a landing floor covering a machine room provided at both front and rear end portions in a longitudinal direction of a frame and a conveying body that is annularly connected between the landing floor and circulates, the landing floor has a box-shaped structure formed by a flat rectangular parallelepiped of which a part or the whole is constituted by a first plane provided horizontally, a second plane opposed to the first plane, and the remaining vertical plane, and the landing floor has a reversible structure in which any one of the first plane and the second plane can be used as a front surface of the landing floor.

Description

Passenger conveying equipment and maintenance method thereof

Technical Field

The present invention relates to passenger conveying equipment such as escalators and moving walks and a maintenance method thereof, and more particularly, to a structure of a landing floor installed at a landing entrance and a maintenance method thereof.

Background

A landing floor installed at a landing part of an escalator as a passenger conveyor generally includes a decorative plate having a tread surface and a frame of a metal plate structure provided on a back surface of the decorative plate and formed by stacking a plurality of components obtained by forming a thin steel plate.

When a user of the escalator walks on the landing floor, the decorative plate forming the tread surface is worn due to friction caused by walking or the like, and the frictional resistance is reduced. At this time, the boarding/alighting floor is repaired and replaced in order to prevent the user from falling down and ensure safety. In addition, when dirt, damage, or deformation occurs, the access floor is repaired and replaced as a general maintenance. Such repair and replacement requires reduction in frequency, the number of parts, and labor required for replacement.

The boarding/alighting floor is a part of the floor, and also has a function of a door for entering and exiting a machine room of the escalator during maintenance work. When the weight of the door is heavy, the worker who opens and closes the door to enter and exit the machine room is burdened with the labor for opening and closing the door, and therefore, reduction of the burden is required. In contrast, a passenger conveyor has been proposed which has a structure capable of facilitating the change of the width of the access floor according to the width of various passenger conveyors and the replacement of the decorative plate due to wear, and which is capable of reducing the weight of the access floor.

For example, the boarding/alighting floor disclosed in patent document 1 is configured by a decorative plate made of a thin steel plate having a surface with irregularities, and a frame body to which the decorative plate is attached. The frame of the landing floor is formed of a continuous body having the same cross-sectional shape, and the continuous body can be cut into a size corresponding to the width of the passenger conveyor.

Disclosure of Invention

Technical problem to be solved by the invention

However, according to the technique disclosed in patent document 1, as a method for attaching and stably fixing the decorative plate to the frame body, in addition to a method for inserting a countersunk screw from a through hole provided in the surface of the decorative plate and fastening the countersunk screw to a screw hole provided in the frame body, a method for bonding the decorative plate to the frame body using a double-sided tape, an adhesive, or the like is also employed in order to eliminate partial floating of the decorative plate. Since the decorative plate is bonded in this way, if the decorative plate is peeled off without particular attention, the frame is often damaged to such an extent that the frame is bent. Therefore, each time the decorative plate is worn out significantly, it is necessary to replace the entire floor panel together with the frame body to which the decorative plate is attached.

The present invention has been made to solve the above problems, and an object thereof is to provide a passenger conveyor in which the frequency of replacement of an access floor is reduced.

Means for solving the problems

The present invention for solving the above problems is a passenger conveyor including: a boarding and alighting floor covering the machine room provided at the front and rear end portions in the longitudinal direction of the frame; and a conveying body which is annularly connected between the landing floors and circulates, wherein the landing floors are in a box-shaped structure formed by a flat cuboid, a part or the whole of which is composed of a first plane which is horizontally arranged, a second plane which is opposite to the first plane and the other vertical planes, and any plane of the first plane and the second plane can be used as a reversible structure of the front surface of the landing floors.

Effects of the invention

According to the present invention, it is possible to provide a passenger conveyor in which the frequency of replacement of the boarding floor is reduced.

Detailed Description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following description and drawings are examples for explaining the present invention, and may be omitted or simplified as appropriate for clarity of explanation. In addition, not all combinations of the features described in the embodiments are essential to the solution means of the invention.

The present invention is not limited to the embodiments, and all application examples conforming to the idea of the present invention are included in the technical scope of the present invention. The present invention can be modified by those skilled in the art without departing from the scope of the present invention. The present invention can be implemented in various other embodiments. Each constituent element may be plural or single, unless otherwise specified.

Fig. 1 is a side sectional view showing an entire structure of an escalator as a passenger conveyor according to an embodiment of the present invention. As shown in fig. 1, in an escalator 1 of the present embodiment, a plurality of steps (conveying bodies) 2 are connected in a loop-like manner and are circulated, and passengers are conveyed between an upper floor 3 and a lower floor 4. In addition, the same reference numerals are given to the escalator 1 as the passenger conveyor 1.

The escalator 1 includes: a frame 5 provided in a building; a handrail 6 provided for passenger safety and moving in synchronization with the steps 2; and balustrades 7 provided on both sides in the width direction of the steps 2 to support the handrails 6 and standing along the longitudinal direction (the traveling direction of the user) Y of the frame 5.

The upper and

lower floors

8 and 9, the handrails 6, the balustrades 7, and the like are supported by the frame 5, and entrance ports on the building side are fixed to both ends in the longitudinal direction of the frame 5. At these landing places, there are an upper landing floor 8 and a lower landing floor 9, which are collectively referred to as

landing floors

8, 9. The

landing floors

8 and 9 are not limited to the application to the escalator 1, but may be applied to a moving walkway. Here, the

landing floors

8 and 9 used in the escalator 1 will be described in more detail.

The width direction of the

landing floors

8 and 9 is an X direction (fig. 3) perpendicular to the longitudinal direction Y of the frame 5. In other words, it refers to a direction perpendicular with respect to the plane of fig. 1. The frame 5 of the escalator 1 includes an upper landing floor 8 and a lower landing floor 9 on which a user lands and descends, and an inclined portion 10 connecting the upper and lower landing floors. A drive machine 12 is provided in an upper machine room 11 in the upper floor 8 to drive a drive sprocket 13.

On the other hand, a driven sprocket 15 is provided in a lower machine room 14 in the lower floor 9, and an endless chain 16 is wound around and continuously driven between the upper and lower drive sprockets 13 and the driven sprocket 14. A pulley 17 is connected to the chain 16 at equal intervals, and each step 2 is attached to the pulley 17. The upper-stage machine room 11 and the lower-stage machine room 14 are collectively referred to as upper-stage and lower-stage machine rooms 11 and 14 or escalator machine rooms 11 and 14, or simply referred to as machine rooms 11 and 14.

The conventional access floor disclosed in patent document 1 is composed of 2 main components, namely, a frame for supporting a load of a passenger, and a decorative plate provided on a surface of the frame and having a tread surface. The decorative plate is formed by using a general technique such as stamping a thin steel plate such as stainless steel into an uneven shape or etching the surface of the thin steel plate to form an uneven shape, and is configured to secure a predetermined frictional force against the sole of a passenger in addition to an appropriate appearance effect indicated by the name of the decorative plate.

In contrast, the

landing floors

8 and 9 in the escalator 1 according to the embodiment of the present invention are not laminated with decorative plates, but basically are constituted by only the frame 18 as a single component. Fig. 2 is a partially enlarged side sectional view for explaining an installation manner and an outer shape of the landing floor in the escalator of fig. 1.

The frame 18 (indicated by reference numeral 19 in fig. 3) is formed of a continuous body of members having substantially the same cross-sectional shape in the width direction of the

landing floors

8 and 9, and extending in a depth direction with respect to the paper surface of fig. 1 and 2, that is, in a width direction X described later in fig. 3, and having an arbitrary length L. Further, the frame 18(19) constitutes the

landing floors

8 and 9 as a single product as described above. In this way, the single-product structure of the

landing floors

8 and 9 constituted by the

housings

18 and 19 are the same object, but for the convenience of explanation of the functions, different reference numerals are given. That is, the

landing floors

8 and 9 function as floor covers for the machine rooms 11 and 14. The frame 18(19) is a structure having a rigid floor cover.

The

frames

18 and 19 are made of aluminum or the like and are manufactured by extrusion or the like, that is, the

frames

18 and 19 as the

access floors

8 and 9 are formed as a continuous formed body having substantially the same cross-sectional shape and being continuous in the width direction X, which is cut at any position in the width direction X by a vertical plane with respect to the width direction X. The

frames

18 and 19 are flat rectangular parallelepipeds, and are partially or entirely formed into box-shaped structures. In addition, the 6 surfaces constituting the box-shaped structure do not need to have all the sealing functions, and may have a shape in which 2 opposing surfaces are opened in a state close to the opening, for example.

In addition, in the

landing floors

8 and 9 of the passenger conveyor 1, in the

frames

18 and 19 formed of the continuous body, a plurality of grooves 20 or ridges 21 (not shown in fig. 3) are densely formed in parallel on 2 surfaces of the upper first plane a and the lower second plane B, which are horizontally provided. One of the first flat surfaces a is exposed in a state where it is initially fixed upward as the

access floors

8 and 9. When the plurality of grooves 20 or ridges 21 are densely formed in parallel, they are continuous grooves or continuous ridges, and they are substantially the same in any name.

In this case, the first plane a needs to secure a predetermined frictional force against the sole of the passenger in order to secure safety, as in the case of the tread surface of the circulating step 2. The other second plane B is directed downward and covers the top plates of the machine rooms 11 and 14, and the edge of the second plane B is supported by the floor frame 22 (a part of the frame 5) through the cushion member 23. In this case, the second plane B does not need to secure friction against the sole of the passenger, and is not exposed, so that the second plane B does not need to be aesthetically pleasing.

In the above description, from the viewpoint of ensuring safety, the plurality of grooves 20 or ridges 21 densely formed in parallel have an effect of preventing slipping, and therefore are advantageous. Further, the ridges 21 provided on the flat plate surface are also advantageous in terms of structural strength because they have an effect of reinforcing the frame 18 as ribs or corrugated plates. Further, from the viewpoint of appearance, an effect of imparting a certain degree of aesthetic appearance can be expected. The

frames

18 and 19 as the boarding/alighting floor require all functions of friction, strength, and beauty for the exposed surface facing upward, but do not require friction and beauty for the surface facing downward and shielded.

The grooves 20 and the ridges 21 can be accurately and easily mass-produced in a continuous body manufactured by extrusion molding using aluminum as a material and having the same cross-sectional shape. In the passenger conveyor 1, the

landing floors

8 and 9 are substantially rectangular parallelepipeds having a flat outer shape, and are formed by 2 surfaces of a first plane a and a second plane B horizontally disposed and 6 surfaces of the remaining 4 vertical surfaces C to F. The

landing floors

8 and 9 have the same shape as the first plane a and the second plane B, respectively, with respect to the frictional force of the soles of the passengers. The area average is used to include also the case of designs where the surface friction is not uniform over the entire surface.

The

access floors

8 and 9 are flat rectangular parallelepipeds having the same front and back surfaces. That is, the first plane a and the second plane B provided horizontally have the same shape, and the grooves 20 and the ridges 21 are formed on the surfaces of the first plane a and the second plane B by extrusion molding as a continuous body having the same cross-sectional shape. In such a manufacturing method, the burden of making the flat rectangular parallelepiped have the same front and back surfaces is not changed, and therefore, the manufacturing efficiency is improved as a whole.

Therefore, in the passenger conveyor 1, when one of the 2 surfaces of the first plane a and the second plane B of the

landing floors

8 and 9 is deteriorated to such an extent that replacement is necessary, if the other is of a usable quality level, the

landing floors

8 and 9 can be set again by turning over. Thus, the passenger conveyor 1 has a reduced number of components for the

landing floors

8 and 9, and is improved in manufacturability and has a longer life.

Thus, the

access floors

8 and 9 can be easily maintained in accordance with wear, and the service life can be extended by increasing the number of times of use, thereby saving materials and reducing the labor for storing and transporting the materials and managing the materials. That is, it is possible to contribute to reduction in the number of types and number of spare parts, the shelf life, and maintenance personnel.

Here, regarding the type of the escalator, a structure having a step width of about 1000mm is the mainstream, but 600mm or 800mm is also available in a case where there is little demand for a building or users. Of course, the width dimensions of the

landing floors

8, 9 can be changed in accordance with the type of the escalator. Fig. 3 is a perspective view of a diagonal member of the ascending/descending floor for explaining a modification.

The landing floor 9(8) shown in fig. 2 is formed by extrusion molding of aluminum to form the frame 18 as a continuous body having a substantially uniform cross-sectional shape. The landing floor 9(8) having such a structure is effective in attaching and detaching the landing floor 9(8) in order to enter the escalator machine room 11, 14 for maintenance work or the like, because weight increase of the whole structure can be suppressed by making the thickness uniform and thin. The upper and lower horizontally disposed flat surfaces A, B of the frame 18 are a continuous body having substantially the same surface shape, and the front and back surfaces A, B have load resistance as treads. That is, in the floor 9(8) composed of the frame 18, the upper plane a is not deformed even when a person steps on the floor, and the lower plane B attached to face the floor frame 22 is not deformed.

Since the frame 19 of the modification of fig. 3 is formed of a continuous body having substantially the same cross-sectional shape in the width direction, the width dimension L of the frame 19 can be easily changed by cutting the continuous body from a long shape to a desired length and using the cut continuous body. Thus, it becomes easy to provide the

landing floors

8 and 9 for the escalator with a wide variety of widths. When the cut surface cut in the traveling direction Y of the user (the longitudinal direction of the frame 5) is observed, the frame 19 is formed of a cavity 28, an oblique side 27, a vertical side 24, an upper side 25, and a lower side 26.

In other words, the substantially same cross-sectional shape with the inclined side 27, the plurality of triangular cavities 28 in the cross section in the width direction X of the

landing floors

8 and 9, and the frame 19 formed of aluminum or the like are used as a material, so that even if a continuous body having substantially the same cross-sectional shape is used, the weight increase of the whole can be suppressed, and the structure is effective in attaching and detaching the

landing floors

8 and 9 for the purpose of entering the escalator machine room for maintenance work or the like.

Further, since the substantially same cross-sectional shape of the frame 19 is a triangular cross-sectional shape having the oblique side 27 in addition to the vertical side 24 (so-called truss (truss) structure is employed), it is effective to effectively distribute the load of the user passing through the

landing floor

8, 9 to the entire frame 19 and to secure the rigidity necessary for the structure of the main body of the

landing floor

8, 9. The vertical edge 24 and the oblique edge 27 are arranged in the vertical direction and the oblique direction with respect to the user traveling direction Y of the

access floors

8 and 9, respectively.

As described above, in the above embodiment, the escalator 1 is described as an example, but in other passenger conveyor such as a moving sidewalk, the

same landing floors

8 and 9 are generally used, and further, since the frame body is formed of a continuous body having substantially the same cross-sectional shape, the frame body can be cut and used in a desired length, and therefore, the width dimension L of the frame body 19 can be easily changed, and the present invention can be easily applied to a moving sidewalk having a wide width. As described above, the passenger conveyor according to the embodiment of the present invention can be applied to a moving walkway or the like in addition to the escalator 1.

[ comparative example ]

Next, the access floor 30 of the comparative example will be briefly described with reference to fig. 4. Fig. 4 is a partially enlarged cross-sectional view of a cut surface of the landing floor 30 in the traveling direction Y of the user. The steel plate landing floor 30 is attached to the floor frame 22 via a reinforcing member 31 attached with a double-sided tape 32 in order to obtain rigidity against the weight of the passenger and the bending stress of the passenger. The landing floor 30 may have the decorative plate (not shown) attached to the uppermost layer thereof in order to secure the frictional force of the upper plane against the soles of the passengers, but the grooves 20, the ridges 21, and the like shown in fig. 2 may be formed on the surface of the landing floor 30.

The following problems occur when the groove 20, the ridge 21, and the like are formed on the surface of the access floor 30 and the floor is attached to other members with the double-sided tape 32. That is, it is known that the upper plane of the access floor 30 is damaged, and when the lower plane, which is the bonding surface, is peeled off from the reinforcing member 31 for maintenance, that is, when the frame body is disassembled, the frame body desired to be left as the reinforcing member 31 is damaged.

The structure of the access floor 30 is a complicated metal plate structure in which a plurality of members formed of thin steel plates are stacked as a frame. In this way, in order to repair and replace a complicated structure having a large number of parts, a corresponding material and labor are required. Therefore, even if the upper plane is damaged after a certain period of use, it is difficult to adopt a method of extending the life in which the entire landing floor 30 is turned upside down to change the lower plane to the upper plane and to expose the usable plane again. In this way, the landing floor 30 cannot be formed in a structure in which the upper plane and the lower plane have the same shape with respect to the frictional force of the passenger's sole.

In contrast, in the lifting/lowering

floor panels

8 and 9 according to the embodiment of the present invention, if one of the 2 upper and lower first and second flat surfaces a and B, which are in a front-back relationship, that is, the upper flat surface a, which is first exposed upward, is degraded to such an extent that replacement is necessary, and the other flat surface, that is, the lower flat surface B, is available in quality, the lifting/lowering

floor panels

8 and 9 can be reversed and set again. The effects thereof have been described above.

The passenger conveyor 1 according to the embodiment of the present invention can be summarized as follows.

[1] The passenger conveyor 1 has: machine chambers 11, 14 provided at both front and rear end portions in the longitudinal direction of the frame 5; boarding and alighting

floors

8 and 9 covering the machine rooms 11 and 14; and a conveying body 2 circularly connected between the landing

floors

8 and 9. The

landing floor

8, 9 is a box-shaped structure composed of a first plane a, a second plane B opposed to the first plane a, and the remaining vertical planes C to F, and formed partially or entirely of a flat rectangular parallelepiped. In this way, since the

landing floors

8 and 9 have a box-shaped structure having load resistance as treads on the front and back surfaces A, B, the strength against deformation can be obtained even on the lower flat surface B attached to face the floor frame 22. The passenger conveyor 1 also includes a moving walkway in which the conveyor 2 is formed of a rubber belt or the like.

The

landing floor

8 or 9 has a reversible (both front and rear) structure in which either one of the first plane a and the second plane B can be used as the front surface of the landing floor. That is, the first plane a and the second plane B are reversible structures in which the frictional force of the surfaces is the same when expressed by the respective area average values, and thus have functions of backup to each other. Therefore, in the passenger conveyor 1, the

landing floors

8 and 9 can be installed even if the upper and lower planes thereof are reversed. In other words, the basic outer shape of the

access floors

8 and 9 is formed of a flat rectangular parallelepiped. The upper and lower planes of the flat rectangular parallelepiped have the same shape in terms of the average value of the area and the same frictional force with respect to the sole of the passenger. The

access floors

8 and 9 may have a tapered structure in which the vicinity of the end edge of the box-shaped structure is inclined, or may have a shape in which the upper side is converged into a parabola and the corner portion has a curvature in the cross section in the Y direction. Further, the first plane a and the second plane B are also included in the present invention as long as they have a shape that is slightly deformed from the viewpoint of ensuring safety by frictional force and from the viewpoint of beauty.

Therefore, in the passenger conveyor 1, when one of the 2 surfaces of the first plane a and the second plane B, that is, the upper plane a is deteriorated to such an extent that replacement is necessary, if the other surface, that is, the lower plane B is of a usable quality, the

landing floors

8 and 9 can be set again by turning over. Thus, the passenger conveyor 1 has a reduced number of the

landing floors

8 and 9 and improved manufacturability. The landing floor can be easily maintained according to wear, can be prolonged by increasing the number of times of use, can save materials, and can reduce labor for storing and transporting the materials and appropriately providing management.

[2] The passenger conveyor 1 preferably further has: balustrades 7 provided on both sides of the carrier 2 in the width direction X and standing along the longitudinal direction of the frame 5; a handrail 6 driven in synchronization with the conveying body 2; and a boarding and alighting floor support structure. In the

landing floors

8 and 9 of the passenger conveyor 1, the first plane a and the second plane B may have the same surface shape. This eliminates the need for designing and manufacturing a mold, and the like, and for performing inspection, and contributes to improvement in manufacturability as a whole. Even if a defective product such as a slight damage occurs on one of the first plane a and the second plane B, only the damaged other plane can be used as a non-defective product. The access floor support structure is a structure in which floor frames 22 formed on the upper plane of both end portions of the frame 5 are placed in contact with the surfaces of the

access floors

8 and 9.

[3] The vertical plane C-F is formed of a continuous body in which 2 opposite surfaces C, D have the same cross-sectional shape among 4 surfaces. The continuous body can be cut into a size corresponding to the width of the step 2. The molded article made of such a continuous body is easy to mass-produce and purchase with the same specifications.

[4] In the passenger conveyor 1, the continuous body is manufactured by extrusion molding using aluminum as a material. Since the continuous body is formed by extrusion, a rectangular parallelepiped having an arbitrary length and the same cross-sectional shape can be formed. The cross-sectional shape forms a hollow portion surrounded by 2 surfaces E, F of 2 surfaces of the first plane a and the second plane B and 4 surfaces of the vertical surfaces C to F. In this way, the

landing floors

8 and 9 can be mass-produced accurately and easily in a continuous body manufactured by extrusion molding using aluminum as a material.

[5] The cross-sectional shape of the continuum forming the

landing floor panels

8 and 9 is a square surrounded by 2 of the respective sides forming the upper and lower 2 surfaces A, B and 2 of the respective sides forming the vertical 4 surfaces C to F, and 4 sides in total. The square cross-sectional shape may be formed into a longitudinal, transverse, or diagonal bar (bar). The continuous body of the above [4] having a square cross-sectional shape made of aluminum and produced by extrusion molding is box-shaped, and by forming a frame inside the box-shaped continuous body, the structure can be further enhanced in firmness.

[6] In the passenger conveyor 1, the continuous body is formed with a plurality of grooves 20 or ribs 21 in 2 surfaces of the first plane a and the second plane B, respectively, in parallel. The grooves 20 or ridges can be mass-produced accurately and easily in a continuous body manufactured by extrusion molding of the aluminum material of the above [4] with the same cross-sectional shape.

[7] The passenger conveyor 1 is suitable as an escalator in which steps 2 are the conveyance bodies 2 of the above-described [1] to [6 ].

The maintenance method (method) of the passenger conveyor 1 according to the embodiment of the present invention can be summarized as follows.

[8] The method is a method of repairing the passenger conveyor 1 described in [1] above, which has the boarding/

alighting floors

8 and 9 covering the machine rooms 11 and 14, with respect to the boarding/

alighting floors

8 and 9 damaged with use. The

landing floor

8, 9 is of a box-type structure. In the above-described boarding/

alighting floors

8 and 9 having a box-shaped structure, the first plane a and the second plane B are in a relationship in which the other is used as a maintenance member for one damaged side. That is, if one is damaged, the other, which is not damaged, replaces its function.

In other words, the first plane a and the second plane B have the same average area value in the unused state with respect to the frictional force of the sole of the passenger, and mutually perform the backup function. Accordingly, if the upper plane a of the vertical planes of the

access floors

8 and 9, which have a flat basic outer shape and are worn to such an extent that they need to be replaced and damaged to be liable to slip, is of the same quality as a new product, the

access floors

8 and 9 are turned inside out and set again so that the surface B faces upward and the surface a faces downward.

Thus, according to the method, the lifting floor is simple and easy to maintain, and can be prolonged in service life by increasing the number of times of use, thereby saving materials and reducing labor required for use.

when one of the first plane and the second plane is degraded to the extent that the plane needs to be replaced, if the other plane is available, the landing floor is turned over and set again.
