Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a passenger conveyor such as an escalator or an electric road, and particularly relates to a body frame structure with high production efficiency.

Passenger conveyors have long been used as ancillary equipment for various commercial products, but recently they have been used for a variety of purposes such as office buildings, urban transportation systems, and pedestrian bridges. f. Also, it is important to pay close attention to the design depending on the application, and to place emphasis on dispersibility, economy, safety, and magnetic force-saving functions.
The needs of stations are also becoming more diverse.

Conventional passenger conveyors that have met the above needs are classified based on design and structure, and are broadly divided into opaque balustrades as shown in Figure 1 and transparent balustrades as shown in Figure 5.

The main structure of the main body frame that supports each overall GI degree is the truss structure shown in FIG. 1 and the beam structure made of 7-bar H steel shown in FIG. 5.

According to the invention, steps 1 and handrails 2 for transporting passengers are arranged in a 91-square shape, and each is driven at a predetermined speed by driving cars 3 and 4. . In addition, a drive machine 6 consisting of a motor 6a and a speed reducer 6b is arranged in the machine room 5 at the upper end. Such a time! It has a mechanism that drives the ribs. Further, the strength of the above-mentioned components is maintained by a main body frame 9 having a truss structure as shown in detail in FIG.
1, it has a structure with golden waves on the inside and outside. In addition, if the relationship between the balustrade 10 appearing in this FIG. 1 and step 1 is explained with reference to FIG. 2, this opaque type balustrade 10
Directly below the guide 2a that guides the travel of the handrail 2, there is a deck 10a, a support column 10b that supports it, and a handrail panel 1.
2 moldings 12a1 and skirt guards 12b are arranged to form the side walls of the step 1, making it a designed structure that has the function of securing the passengers riding on the step 1 and guiding the handrail 2. On the other hand, the main body frame 9 has rails 13 and 14 on which the parapet IO and the step 1 run.
The bottom surface is covered with a bottom plate 9i that receives oil and dust flowing out from each of the passenger conveyors (tables), and one side is covered with an exterior plate 11 and the bottom surface is covered with an exterior plate 16. Although not shown in this drawing, the surface of the exterior plate 16 is usually beautifully illuminated with decorative lights, and the piping for this is provided between the bottom plate 91 and the exterior plate 16.

Next, details of the main body frame 9 composing the fs1 diagram will be explained with reference to FIGS. 3 and 4. In the figure) the main frame 9 of the lath structure is the main strength member that becomes the foundation of the man conveyor, and includes members 9a mounted on the building, a drive vehicle 3f: a support base 9b to be attached, a support base 9c on which the drive machine 6 is mounted, left and right Cross beams 9d and 9e that hold money, parapet supports 9f, 9g, 9h,
A bottom plate 91, a mounting base 9 for supporting the piping of the bottom lighting equipment, a hunt rail drive vehicle 9j, a guide roller 9, etc., which are required when a transparent type handrail is mounted on the truss-structured main body frame 9, and 9m. The rail mount 9n, the board mount 9p, etc. are usually arranged symmetrically. These miscellaneous members are integrally welded to the upper chord member 9A, lower chord member 9B, and vertical member 9D of the main body frame 9, and are generally connected to the parapet support (9g, etc.).
is attached to the upper chord member 9A, and the support stand 9b, rail attachment stand 9n, etc. are attached to the vertical member 9D.

Here, the dimensions of the main body frame 9 are W1 = 15QQ to 1600, -17 meters within the range of the interval W1 of the upper chord member 9A to accommodate the step 1 and the rail 137z, and the depth Hl of the machine room 5 is Ht= to store machine 6
The length of the body frame 9 is set to 1000 to 1200 mm, and the total length of the main body frame 9 is determined according to the floor space in which the passenger conveyor is installed. The longer this total length is, the stronger the main body frame 9 needs to be, and the deflection δ'k caused by the full load of the passenger conveyor.
In order to keep the dimensions constant, measures such as increasing the cross-sectional area of the upper chord member 9A and lower chord member 9B, adding reinforcements 9E and 9F at the bottom, and adding reinforcement 9Gtl to prevent deformation during transportation are taken. is normal. Note that the maximum value of the deflection δ needs to be approximately 10 mm or less in order to maintain smooth running in step 1, and for this purpose, the second chord member 9A withstands compression and the lower chord member 9B withstands tensile force. The size is selected and the vertical member 9D is also reinforced each time.

As described above, in the main body frame 9 of the conventional truss structure, the opaque type balustrade 10 shown in detail in FIG.
Now, inside the parapet panel 12. Since the exterior board 11 and two layers of design body are required on the outside, there is a slight economic disadvantage.

This disadvantage can be ignored as it corresponds to the need for the configuration of the parapet 10, but as mentioned above, the configuration ru of the main body frame 9, which changes the size of the upper chord 9A etc. depending on the length of the passenger conveyor, We cannot deny the economic disadvantage of mass production (economics) and increased weight due to changes in manufacturing.

On the other hand, unlike the one shown in FIG. 1, a passenger conveyor that uses H steel for the main body frame 15 and further has a transparent handrail 16 mounted thereon has a construction roughly as shown in FIGS. 5 and 6.

The configuration of FIG. 5 will be explained with the parts that are duplicated with those of FIG. 1 as much as possible omitted. In the figure, the rotating bodies such as the step 1 and the handrail 2, and their drive systems (driver 6, etc.) are the same as in FIG.
It uses a main body frame 15i with a beam structure arranged opposite to each other with H articulation on both sides, and furthermore consists of a guide 6a via a pillar 15ai above this, a transparent glass parapet panel 16b, an inner deck 16c, an outer deck 16d, a skirt guard 16e, etc. A parapet 16 is mounted on it, the entire side surface is covered with an exterior board 17, and the bottom surface is covered with an exterior board 18. In addition, this main frame i-, 15Fi & 15 is very similar to the above-mentioned main frame 9 in that it supports the entire strength of the conveyor, supports rails 13 and 14, and is equipped with a crossbeam 15b and a bottom plate 15cTh. , The major difference between these metals is that the height H2 of the H steel part is extremely small compared to the height Ht of the machine room 5 (Ht vs. H2 = ioo vs. about 50 to 60), which makes it possible to handle the cargo with a smaller size. No, it has a configuration that is advantageous for transportation. However, contrary to this advantage, the support 1, which is a large structure between the main body frame 15 and the outer deck 16d,
5a (i7) to ensure a predetermined height Hst, which is one of the problems with this structure.

Above, representative examples of the form of the handrails have been explained in detail with emphasis on the structure of the main body frame of a conventional passenger conveyor, but it can be seen that each main body frame has the following problems.

■ Truss structure body frame 9° (1) It is necessary to change the design and manufacturing according to the length of the passenger conveyor, and productivity is lacking.

(2) The framework is large, which is disadvantageous in terms of packaging, handling, and transportation, and there is also the problem of increased weight.

2. Beam structure main body frame 15° (1) Although it is small and convenient for handling and transportation, it requires columns 15a to support the 16K gold railing, which increases the cost.

(2) The size of H steel is limited in the market, and it is unreasonable to use H steel, which has excessive strength, even for short passenger conveyors, for example.

Furthermore, there are serious economic disadvantages of the conventional main body frame due to problems in the connection between the parapet structure and the exterior panels 11 and 17.

This problem will be explained using the configuration shown in FIG. 6 as a representative example. First, to explain the parapet 16, the parapet panel 16
Since considerable strength is required to support the rail 2 and guide 16a at the lower end of b, the column 15a whose lower end is directly connected to the main body frame 15 and the parapet support 19 are strengthened with bolts 20. The balustrade panel 16b (z) is firmly attached to the balustrade support 19 using the pressure bonding plate 21, and the outer deck 16di is firmly attached to the balustrade support 19 using the support 22.The detailed structure of this is shown in Fig. 7. and
The outer deck 16d is actually fixed to the support body 22 by screwing a screw 16g-1 into a fixing seat 16f provided on the back surface thereof. Furthermore, the exterior board 17 is usually supported and fixed by fixed JA, 23, and 24 attached to the parapet support 19 and the pillar 15a. Such a fixing structure is substantially the same in the case of the exterior plate 18 on the bottom surface.

The mounting structure of the balustrade 16 and the exterior plate 17 described above has the following economic problems.

(1) Since the height of the main body frame 15, which is a strength member, is low, the balustrade support body 16 is required to support the balustrade panel 16b. This is unnecessary if the upper surface of the main body frame 15 is at a height that reaches close to the parapet 16. In this case, of course the support 15a is also unnecessary.

(2) To fix the outer deck 16d'i, the fixed seat 16f
It is necessary to arrange the supports 22 at fine pitches. If you include 16g of screws, the number reaches six.

(3) A large amount of fixing devices 23 and 24 are also required, and since the fixing device 24 can only be attached to a position where the support column 15a is present, it is unnecessary to join the exterior plates 17 (joint g) in a place where there is no support column 15a, for example. However, it also imposes restrictions on the side of the exterior plate 17.

This increase in the number of parts not only increases manufacturing costs, but also
This is the biggest economic bottleneck because it increases assembly costs.

The form shown in Figure 8 is also conceptually known as an idea that improves the structure of the main body frame, handrail, and exterior plate described above and dramatically increases its mass production (economic) efficiency. There is. The structure of FIG. 8 is shown for a transparent type similar to the conventional parapet form explained in FIG. ), and a substantially U-shaped main body frame 25 formed by an upper surface portion 25c that protrudes inwardly.
This is a metal object made by bending a steel plate. And a connecting board 2 to support the parapet panel 26.
7 is installed, and as an aid for strength, ■Vigenzai 25d (
i7 or a crossbeam 25e that supports the rail (not shown)
(The main body frame 25 is constructed by providing the main body frame 25.The final purpose of this structure is to have the bottom surface portion 25a and the side surface portions 25b serve as the metal exterior plate 17.

However, the main body frame 25 having this structure has the following drawbacks, so it has not been put into practical use yet. That is, in the configuration shown in FIG. 8, since the outer surface of the main body frame 25 is exposed, there is a thermal strain Z8 of the welded part Z of the crossbeam 25e, and a strain Zb caused by the deflection δ explained in FIG.
etc. clearly appear on the surface, making it impossible to put it to practical use as an exterior wall of a passenger conveyor, which is a designed part. moreover,
The connecting board 27 is a design component below the parapet, but since thick and sturdy steel is used to support the parapet panel 26, the design expression is similar to that of aluminum or stainless steel, as is the case with recent passenger conveyors. This results in a significant decrease in product value.

As an alternative idea to the configuration shown in FIG. 8 above, the one shown in FIG. 9 can also be considered. This is based on the idea of the main body frame 25, and has a bottom part 28a1, a side part 28b1, and an upper surface part 28.
c. The support portion 28d is integrally bent and formed to form the main body frame 28, and a thin cosmetic material 29 (thickness t) is attached to the surface of the main body frame 28 to eliminate the distortions Za and Zb.
'ii: It is something that is hidden. This structure is such that the height h from the bottom surface to the top surface of the passenger conveyor is equal to the depth of 5 body frames 28 at once, and the pillars 15a, parapet supports 19. Outside deck 16d gold etc.
It has been cut and removed, and the additional parts are about 30-4 meters long for reinforcement. - Although the structure shown in Fig. 9 has a minimum number of parts and is economically effective, it has the following design problems that cannot be overlooked.

(1) Although it is necessary to make the upper surface part 28c strong in order to fully support the balustrade panel 26, which is the main strength member of the balustrade, in order to cope with this, it is necessary to increase the entire thickness of the upper surface part 28c. Therefore, of course, the surface part 2 is integral with this.
8a111Ill and the thickness of the portion 28b also increases. This completely negates the aim of weight reduction and is not practical.

(2) The exterior part and the deck part are the only design expressions of the cosmetic agent 29, which has the drawback of not being able to meet a variety of needs. In other words, while city-grade materials such as stainless steel plates and large buried stones are increasingly being used as exterior materials, thin cosmetic materials 2
9 cannot bring out that sense of luxury and electricity. In addition, the material for the upper surface portion is mainly stainless steel, and cannot match the high quality of this material.

All the advantages and disadvantages of J have been explained above regarding the structure of the conventional passenger conveyor and the improved structure that has been considered recently, but in either case, it is not satisfactory in terms of economy and design.

[Purpose of the invention]

In view of this point, the present invention has been made to provide a passenger conveyor 'ftflL which is light in weight, effective in mass production, and excellent in design by completely improving the structure shown in FIG. 9.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention comprises at least a side surface and an upper surface of the main body frame as a flat plate continuously provided in the entire length direction of the passenger conveyor, and an outer deck and an exterior covering are provided on each surface of the main body frame. By attaching it to the base, there are no restrictions on the material and thickness of the outer deck and the outer sheathing board itself, and the structure is simplified for each attachment.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.

In Fig. 1θ, the side surface 31a stands upright on the exterior side on the vertical plane of the flat plate, and the parapet panel 26 on the horizontal plane of the flat plate from the exterior side.
The upper surface part 31b bent to the side constitutes the main body frame 31 as the minimum member, and the exterior plate 3 is attached to the side] IR part 31a.
2 and the entire outer deck 33 is attached to the E surface portion 31b. Here, the exterior plate 32 is fixed with a fixture 32a between it and the main body frame 31, and its upper end is covered with a molding 34, and when the thickness of this exterior plate 32 changes (for example, when the thickness of the exterior plate 32 changes) If thick marble is used), fixing device 32
Change in thickness of a and protrusion of molding 34 - tdX
The width W2 of the main body frame 31 is always kept constant.

In addition, the outer deck 33 and the molding 34 are fixed to the -F side part with screws 35, and the strength 1 necessary for the parapet panel 26 is also fixed.
Reinforcements 36 are appropriately placed to provide visibility. In addition, the height hh of the main body frame 31 is always a constant dimension and is set at C.
When the thickness of the outer deck 33 changes, the thickness is increased or decreased by 1 based on the upper surface portion 31b. On the other hand, the bottom part 31c of the main body frame 31 may be integrated with the side part 31a, or there is no problem as long as the two parts are integrated by welding or screwing.

In this way, by making the main body frame 31 a continuum of at least its top surface, side surface, and flat plate, there is an advantage not found in the conventional figures 6, 8, and 9. (1) The material of the outer deck 33 can be freely selected without detracting from the design. In addition, the parapet support 19 and the support 2
2 is no longer necessary, and the outer deck 33 can be installed using the upper surface part 31b.
Can be fixed anywhere in the longitudinal direction.

(2) There are no restrictions on the material or thickness of the exterior plate 32,
Furthermore, since the side surface 31a, which is the mounting surface, is continuous, the fixture 32a (i7) can be mounted at any desired position.This can be done no matter where the joint gg of the exterior plate 32 is located.

(3) The cross-sectional dimensions of the main body frame 31 are always constant during iC manufacturing, and any significant distortion of its long surfaces will never appear on the surface.

etc. can be mentioned.

〔Effect of the invention〕

According to the present invention as described above, there is an advantage that a passenger conveyor with a small number of parts, excellent design, and excellent economic efficiency can be provided.

It should be noted that the present invention is not limited to the illustrated embodiment, and modifications as shown in FIG. 11 may also be considered. In this example t, the main body frame 37 is bent at the side and top parts by providing reinforcement 37at as a structure, and supporting the balustrade (flannel 26) is done by a separately provided balustrade support 38, which is attached to the top part 3. An outer deck 39 consisting of a side wall 9a and a side surface 39b is mounted to cover the upper surface of the parapet and the 1: end of the outer panel 40.

It is clear that even in this case, the sound effect of the present invention can be achieved as is.
