Description

  The present invention relates to a design improvement method for a passenger conveyor including a handrail drive device assembly for driving a handrail and a balustrade design for covering the handrail drive device assembly.

  In the conventional method for repairing passenger conveyors, when the design is repaired, the existing handrail drive device assembly is replaced with the latest type, so the passenger conveyor operation is suspended for a long period of time and the repair work is carried out. From measures such as how to shorten the construction period under long-term operation stoppage, new passenger conveyor components are prefabricated to a considerable extent in factories in advance to reduce work time at the site. I am trying. However, the replacement of the existing handrail drive assembly with a major truss modification is difficult because it is difficult to adjust the customer schedule and it must be carried out under the circumstances where there are many local restrictions. Is the current situation. Furthermore, there is a problem that customer complaints occur because a space that cannot be used over a wide area in a building is generated over a long period of time. This is a major adverse effect on the expansion of the passenger conveyor repair business, and there is a need for improvement. Production constraints and customer schedule issues necessitate strict management and operation of repair parts supply and construction schedules. This is a factor that increases the cost of design / production and refurbishment.

In the prior art, a design method that enables a wide range of designs beyond the traditional balustrade design frame by enabling the attachment of heavy plate weight panels etc. to the support pillar of the passenger conveyor, which is a member constituting the balustrade design (For example, see Patent Document 1).
In order to realize such a construction method, it is necessary to measure the strength and rigidity of the support column by replacing the support column with a strong one in order to compensate for the added load. Furthermore, it is considered that the manufacturing accuracy of the balustrade design and the manufacturing accuracy of the supporting column on the side where it is attached are required to be high, and it takes a great deal of time and money to assemble and adjust the balustrade design. In addition, the simple balustrade design mounting structure remains a problem in response to earthquakes.

Embodiment 1 FIG.
An embodiment according to the present invention will be described with reference to FIGS. FIG. 1 is a side view showing a configuration of a passenger conveyor according to an embodiment of the present invention. 2 is a perspective view of part A in FIG. FIG. 3 is a side view showing the upper manual balustrade design portion in the first embodiment. 4 is a cross-sectional view taken along line IV-IV in FIG. FIG. 5 is an enlarged view showing a portion J in FIG. FIG. 6 is a perspective view showing the overall configuration of the passenger conveyor according to the embodiment of the present invention.

In the manual balustrade design portion at the top of the passenger conveyor in the passenger conveyor having the step 4 shown in FIG. 1, the rubber handrail 2 applies the driving force from the handrail driving sprocket 6a driven by the driving machine 1 provided below the existing floor board 10 The chain 14 is transmitted to and driven by the handrail sheave 6c integrated with the handrail sprocket 6b. The intermediate sprocket 8 applies tension to the chain at an intermediate portion of the handrail chain 14.
As shown in FIGS. 3 and 4, the handrail sprocket 6 b and the handrail sheave 6 c that are integrally structured are supported by a sheave support 12, and are collectively referred to as a handrail drive device assembly 9. The handrail drive device assembly 9 is disposed on the left and right sides of the manual balustrade design portion on the upper part of the passenger conveyor, and is firmly and accurately fixed to the upper surface 20a of the upper truss body frame 20 together with the handrail drive device mounting frame 13. The lower manual balustrade design portion has a structure in which only the handrail sheave 6c is arranged to follow the upper handrail driving force. The handrail drive sprocket 6a, the handrail sprocket 6b, and the handrail sheave 6c use the existing products as they are, so that no new production is necessary. By using them, the synchronization speed of the rubber handrail 2 and the step 4 changes at all. This eliminates the need for extensive adjustments.

FIG. 2 is a perspective view of part A of FIG. 1 in which new manual balustrade designs 5a and 5b having an integrally formed structure made of aluminum, for example, are attached to an existing handrail drive device assembly 9 of a passenger conveyor according to an embodiment of the present invention. It is shown as an example.
The illustrated balustrade design shown in the drawing shows a panel-type opaque balustrade design, but a glass-type transparent balustrade design has a similar integral structure. Moreover, although the figure shows the new balustrade design drawing of the lower manual part, the upper manual part is the same.
New design parapet design R hand 5a and L hand 5b provided on both sides of step 4 is a conventional manual balustrade design structure divided into an inner deck, an outer deck, a main deck, and a corner deck of a passenger conveyor. Whereas the handrail drive assembly 9 is sandwiched, the inner deck 11a and the main deck 11b are made of, for example, aluminum and are integrally formed as shown in FIG. 5, and an opening for the handrail sheave 6c. Assembling the newly designed manual balustrade design R-arbiter 5a and L-arbiter 5b with the structure provided with 17a, 17b, the existing mounting bolts 18a, 18b are assembled using the prepared holes 13a, 13b of the existing mounting bolts 12a, 12b. Thus, the shape and configuration do not require any additional modification to the base plate 19. The existing mounting bolt 7 is used as it is.
The corner deck 11c has an independent configuration as in the prior art so as to be movable for adjusting the gap between the passenger conveyor and the building side.
The inner panels 16a and 16b have many choices depending on the required design. Generally, a stainless steel panel is used for an opaque balustrade design, and a glass panel is used for a transparent balustrade design. After assembling the balustrade design with the same configuration as before, it is incorporated into the inner deck 11a. That is, the selectivity of an opaque balustrade design or a transparent balustrade design is made compatible.
The assembly of the inner panels 16a and 16b after the balustrade assembly is the same as the conventional configuration, and therefore the assembly workability is simplified as the deck portion is formed as an integral structure. The new annual balustrade designs 5a and 5b of the aluminum integrated prefabricated structure have a left-right symmetric structure and are installed on the upper and lower portions of the passenger conveyor and cover the left and right existing handrail drive assembly 9.
In addition, in all the ranges excluding the upper and lower parts of the vertical balustrade design part, it is continuously configured with the integrally formed aluminum cross section shown in FIG.

  And as a whole structure of a passenger conveyor, as shown in FIG. 6, the truss 20 which has the upper surface 20a, and the exterior 21 are provided. The handrail drive device assembly 9 including the handrail sheave 6c for driving the handrail 2 is used as an existing handrail drive assembly 9 and has been modified to new balustrade designs 5a and 5b.

  As described above, in the embodiment according to the present invention, the balustrade design of an integrally formed prefabricated structure made of aluminum is used. However, the same effect can be obtained as a balustrade design of an integrally formed prefabricated structure made of resin, for example, plastic. It is obvious to get.

  The present invention provides a method for refurbishing a balustrade design of an existing passenger conveyor into a newly designed balustrade design in a short period of time, including preparations and cleanup that occur before and after actual work, and restoration work of the passenger conveyor for about one week. It is possible to refurbish to the latest balustrade design.

  The present invention is a repair method in which an existing handrail drive device assembly of a passenger conveyor is covered with a newly designed balustrade design while leaving the handrail drive device assembly of an existing passenger conveyor. As shown in FIG. 6, many of the handrail drive device assemblies 9 of the existing passenger conveyor are arranged in the manual balustrade design at the upper part of the passenger conveyor, and the rubber handrail is obtained by obtaining driving force from the driving machine in the upper truss 20 directly below. It has a rotating structure. Therefore, the upper truss 20 is firmly and accurately assembled to the upper surface 20a. A method of repairing the existing handrail drive assembly 9 so as to cover the existing handrail drive assembly 9 with a newly designed balustrade design that is manufactured by integral molding while maintaining the existing state without replacing the existing handrail drive assembly 9 with the latest type. It is.

  According to the present invention, the handrail drive device assembly of the existing passenger conveyor is left, and the existing balustrade design is repaired, so that no major remodeling is required. This is a parapet design refurbishment method that can shorten the construction period, which is the most problematic of conventional renovation work. Replacing the existing handrail drive device assembly to the latest type requires a long construction period due to the replacement of rubber handrails and handrail guides, mounting modifications to existing trusses, and other related component changes and countermeasures. It can be refurbished to the latest balustrade design in about one week, including preparatory work and cleanup that occur before and after actual work, and restoration work for passenger conveyors.
