Description

[Detailed Description of the Invention] The present invention relates to a passenger conveyor such as an escalator or an electric road, and in particular to an aging passenger conveyor, it efficiently applies new technology such as increasing safety, saving energy, and modernizing the design. Regarding the installation method. .

Conveyors have been used as an accessory for commercial buildings, but recently they have become popular in a wide variety of fields such as office buildings, urban transportation, and pedestrian bridges.

The characteristics of recent passenger conveyors include the enhancement of safety measures accompanying the expansion of the user base, the application of new materials brought about by advances in manufacturing technology, and an orientation toward energy conservation. This has been achieved by taking advantage of the needs of the times.

On the other hand, conventional passenger conveyors (particularly the type G4, which was popularized in the early stages of use) have a configuration in which the original power rudder of the passenger conveyor is made into one point, as shown in FIG.

The main feature is that the step 1 and handrail 2 for carrying passengers are arranged in an endless manner, as shown in figure g1.
Each of L1 has drive wheels 3 and 4 and is driven at a predetermined speed. Further, in the upper machine room 5, a drive machine 6 consisting of a motor 6a and a speed reducer 6b is arranged, and the steps 1 and the handrail 2 are connected by checks 77 and 8 that transmit the rotation of the gear 6C of the drive machine 6. It has a mechanism to drive a driving body. Further, the above-mentioned components are supported by a main body frame 9 having a strong truss structure, and the inner and outer surfaces thereof are covered with a parapet 10 and an exterior plate 11.

The passenger conveyor shown in FIG. 1 has a balustrade type generally called an opaque type, and the material of the balustrade panel 12 is stainless steel, a painted plate, or acrylic resin. This balustrade shape is opaque because the drive wheel 4 was used as the only method to drive the handrail 2 in the early days of passenger conveyors becoming popular, and it was not possible to use see-through material for the balustrade panel 12. . However, in recent years, due to advances in single-slide drive technology, transparent balustrades that have moved away from the structural design shown in Figure 1 have become mainstream, and the harmonization with architectural design and the advancement of the balustrade design have contributed to the commercial value of the entire passenger conveyor. It is considered important to the extent that it makes a decision. For this reason, balustrade designs have changed in line with the trends of the times, and the material used to create them has also evolved from the traditional aluminum alloy to stainless steel, which has a high-class image.

As mentioned above, when the importance of railing design begins to be recognized, the age of passenger conveyors that were installed 1000 to 2000 years ago becomes noticeable, and there is a demand for a new design and the use of bulky materials.

On the other hand, the characteristic difference in terms of safety between the old and new passenger conveyors is that steps 1 and 1 shown in Figures 2 and 3.
It is in 3. The conventional Step 1 consists of a 1m aluminum alloy crease with many irregularities on its surface and a riser 1b made of a thin plate simply bent into a drum shape, but the recent Step 13 has a Ri! j) Both the riser 13g and the riser 13b have unevenness, and are configured to precisely engage with the step 13 member or the comb (not shown) of the entrance/exit to prevent the human body or clothes from being drawn in, which could lead to personal injury. In addition, the most recent and rated safest step is Ri! j) A caution band 13c made of reinforced resin around 13a,
Place 13d, 13e, and 13f, and adjust the color tone of this caution zone (
It is a mechanism that psychologically prevents people from approaching dangerous areas due to the attention-inducing effect of increasing the risk (yellow). In addition, in a safer step, the side caution bands 13e and 13f
The top surface is made one step taller to prevent the step from approaching the side wall through the anastomosis, and the glue IJ-) 13a and 13b are replaced with stainless steel to realize a durable step that does not break.
There are also some products that have been effective in terms of both durability and safety.

The various measures to increase safety represented by steps are as follows:
Over the past few years, it has become extremely complete, and although not shown in the drawings, it is equipped with a safety device for handrail entry and exit, a step abnormality detection device, and various track maintenance devices, which contribute to the protection of the human factory.

Furthermore, recent passenger conveyors are oriented toward energy-saving operation as a social need, and comprehensive economical designs have been implemented such as improving the transmission efficiency of reducers, reducing friction loss, and reducing the weight of rotating bodies. There is. As a result, it has become possible to save 30 to 5,091 times more electricity than the man conveyor used a few years ago.

As explained above, recent passenger conveyors have made significant progress in terms of design, safety, and economy, as well as quality. Attempts are being made to rejuvenate the skin by applying the above new technology.

However, since the passenger conveyor is generally installed in the center of the store and serves as an important service facility for customers entering the store, it is not appropriate for the store to suspend the passenger conveyor for the final period for the above-mentioned rejuvenation. The current situation is extremely difficult for the company's business. In particular, it is not allowed to close the store to repair the passenger conveyor, and the amount of inconvenience this renovation will cause to general customers is unimaginable.

For this reason, it is not possible to renew the design of the railings, save energy, or even make improvements to improve safety, which should be taken at the earliest opportunity, due to the length of time required for modification.

In view of this point, the present invention has been made in order to provide a configuration that can implement the above-mentioned rejuvenation measures in a short period of time, and as a result, it will widely spread the safety enhancement of existing passenger conveyors.

Here, the detailed structure of a conventional passenger conveyor will be explained with reference to FIG.

Mounting base 9 and 9m to support rail mounting base 9n, etc.
, the board mounting base 9p, etc. are usually arranged symmetrically. In addition, these miscellaneous members are attached to the main body frame 9.
It is integrally joined to the upper chord member 9A, lower chord member 9B, and vertical member 9D by welding, and generally the parapet support stand (9g, etc.) is connected to the upper chord member 9, the middle support stand 9b, and the rail mounting stand 9n.
etc. are attached to the vertical member 9D.

Further, the dimensions of a conventional passenger conveyor are generally 1500 to 1600 milJ meters in order to store the step 1, rail 14, etc. within the interval Wl of the upper chord member 9A, and the depth Hl of the machine room 5 is the length of the worm of the main length. The height is set at 1000 to 1200 mm, which corresponds to the height of the reduction gear (driver 6).

The above dimensions have been set with plenty of room in each part based on the previous design philosophy that prioritized the sturdiness of the equipment, resulting in a structure that is slightly larger than modern passenger conveyors. There is.

In contrast to such conventional passenger conveyors, the present invention utilizes a main body frame 9 (hereinafter abbreviated as the first frame 9) with a truss structure and mounts a recent passenger conveyor thereon. This rounded design eliminates any change in the attractiveness associated with rejuvenation, significantly shortens the repair period, and provides an economical installation method.
