Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handrail for a passenger conveyor such as an escalator or an electric road, and particularly relates to a method for installing a handrail railing suitable for saving labor and improving accuracy when assembling the handrail at an installation site.

Normally, the parts of a passenger conveyor are manufactured in a manufacturing factory, and then precisely assembled and completed in the building where the passenger conveyor is installed.In general, it takes about 30 days to manufacture the parts at the factory, and then to the installation site. Normally, two to three engineers spend 30 to 60 days on assembly work, or up to 100 days, and most of the days required to complete a man conveyor are spent on assembly work.

Products such as conveyors, which are made to order for each customer, have unique performance and cost advantages, as well as the ability to shorten the period from order receipt to completion as much as possible to meet demands for short delivery times. This is also a selling point and an important proposition for people involved in the manufacture of passenger conveyors.

However, conventional man conveyors have a wide variety of component parts, and require inefficient work at the installation site where most of the work must be done by hand. This has a major and fatal impediment that it is impossible to plan the work process for the construction work alone because it has to follow the progress rate of the construction work.

Of the conventional passenger conveyors, the structure of the type that emphasizes transparency without using supports on the railings is as shown in Figures 1 and 2. It is installed with an installation angle of 30 degrees from floor 1 to upper floor 2, and generally, section A of the curved section on the lower floor and section B of the curved section on the upper floor are fixed parts with respect to the floor height H. The variation in floor height H is always constant.
For example, when H=3 m or 4 m, section C of the inclined straight section is changed each time to match the predetermined floor height.

The strength is maintained by a step 3 arranged endlessly between the lower floor 1 and the upper floor 2 for carrying passengers, a rotating body such as a band rail 4, and a panel 5 made of thick glass. It is made up of main parts such as the parapet 6, and a strong frame 11 that maintains the strength of these main parts and also attaches a driving wheel 7, a driven wheel 8, a floor plate 9, a skirt guard 10, etc. .

Among these structures, a driving vehicle 7, a driven vehicle 8, a floor plate 9
etc., are assembled in advance in a manufacturing factory in a precise and efficient manner, and then transported to the installation site in a state where they are attached to a frame 11, which is a strength member.

The frame 11 makes it look as if it has been packaged firmly, maintaining the same precision as in the manufacturing factory, and waiting for the next process.

On the other hand, regarding the handrail section 6, which constitutes the majority of the parts constituting the passenger conveyor, the parts constituting this are the panel 5, the skirt card 10, the deck 13 in the band rail frame 12,
Reinforcing materials 14 and 15, rollers 16, mounting brackets 17 and 18, rail guide 19, core material 20, bolt 2
1, etc., and since most of them are designed products and do not want their surfaces to be scratched or deformed, they are carefully packaged and transported to the installation site, and then assembled.

While this ensures the protection of each part during transportation, it has the fatal disadvantage of increasing the number of days needed for installation, and requiring poor assembly precision that is unique to the installation site.

However, very recently an assembly method as shown in FIGS. 3 and 4 has been proposed.

In this method, as shown in Figure 1, the entire length of the passenger conveyor is assembled by assembling the railings of section A on the lower curved section and section B on the upper curved section at the manufacturing factory. After this is carried into a building and the assembly of sections A and B is fixed to the frame 11 at the installation site, section C of the inclined straight section is joined.

Now, to explain this using section A of the lower floor curved section as a representative, the panel 5 subdivided as shown in Figure 3 (showing the state with the rail 4 removed) and Figure 4.
a, Packing P1 around the panel 5b as a base,
P2 is arranged to provide a band rail frame 12, a band rail guide 19 for guiding the band rail 4, a core material 20, a cover 25, an outer deck 22, a support 23, a pressure bonding plate 24, and other elongated members.

All of these members have a structure in which the ends of panels 5a and 5b are tightly crimped with covers 25 and bolts 29, forming a sturdy assembly with panels 5a and 5b as strength members, and installed in this state. After being delivered to the site, it is fixed to the frame 11 using mounting brackets 17 and 18.

However, in the method of forming an assembly based on the glass panels 5a and 5b as described above, the weight of the band rail frame 12, band rail guide 19, outer deck 22, support body 23, crimp plate 24, etc. is quite heavy, approximately 100 kilograms, and is configured to be supported by panels 5a and 5b as is;
Furthermore, since the distance between the band rail frame 12 and the outer deck 22 is approximately 1 meter, excessive torsional force may be applied to the panels 5a and 5b during transportation. Accidents of breakage frequently occur, and there are defects that fundamentally overturn the form and delivery method of this type of assembly.

In view of this, the present invention has been made with the object of providing a balustrade configuration that is suitable for maintaining the overall strength of the balustrade assembly, improves the efficiency of balustrade assembly work at the installation site, and has high assembly accuracy. It is something that

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In FIG. 5, the basic structure of the passenger conveyor is completely the same as that of the conventional one, but in the present invention, the band rail frame 12 and the support body 23 are installed in the vertical direction with respect to the handrail section explained in FIGS. 3 and 4, etc. The present invention is characterized in that a support column 26 is provided to connect the panels 5a and 5b, and the panels 5a and 5b are removed from the assembly.

Here, in the side direction of the support column 26, as shown by the phase line in FIG. 27 and is firmly fixed.

As before, a band rail frame 12, a band rail guide 19, and a core material 20 are provided on the upper and lower sides.
, the support 23, the pressure bonding plate 24, and the outer deck 22 are fixedly arranged, and are connected by a new support 26 to prevent excessive twisting force from being generated on the panels 5a and 5b as in the conventional case. In addition, the weight of the trench member is supported by supports 26.

In this case, the support column 26 is installed after the assembly arrives at the installation site and the mounting brackets 17 and 18 are fixed to the frame 11 and the panel 5a
and 5b are removed after incorporation.

By doing this, the panels 5a and 5b can be efficiently and precisely assembled at the manufacturing factory without being damaged, and the numerous members on the upper and lower sides can be assembled efficiently and accurately at the installation site. It can be transported to

Therefore, it is clear that extremely efficient installation work can be carried out at the installation site.

Note that this is of course applicable not only to section A of the curved section on the lower floor side, but also to section B of the curved section on the upper floor side.

According to the present invention described above, there is an advantage that the efficiency of assembly work at the installation site is increased and that a railing for a passenger conveyor with high accuracy can be provided.
