Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an escalator installation method,
In particular, the present invention relates to a construction method suitable for installing escalator handrail members.

[Conventional technology]

Traditionally, the installation work for escalator handrails was
After completing the installation of the frame and internal components such as guide rails and step chains,
Boards were placed on the multiple front roller shafts provided on the step chain, and the boards were used as scaffolding for carrying and installing the parapet members.

[Problem that the invention seeks to solve]

However, high-floor escalators, the number of which has been rapidly increasing in recent years, have a floor height of 20 m and a slope distance of 20 m.
Some of them can reach up to 40 meters, so if you try to install the handrails of such high-floor escalators using the above-mentioned conventional method, workers will have to climb a long distance on scaffolding boards. As a result, a great deal of labor is required to transport the parts, resulting in poor efficiency and problems with work safety.

Therefore, an object of the present invention is to provide an escalator installation method that allows work to be carried out efficiently and safely.

[Means for solving problems]

The above object is to provide a frame having an intermediate inclined part between an upper horizontal part and a lower horizontal part, a drive sprocket and an idler sprocket disposed in the upper and lower horizontal parts of this frame, and a drive and idler sprocket. A step chain with a large number of front wheel roller shafts wrapped between the steps and a guide rail extending along the longitudinal direction of the frame to guide the step chain are assembled, and then the balustrade member is assembled. In the escalator during the installation process, a predetermined number of front wheel roller shafts are placed and fixed on the escalator, and the work cart is equipped with an operation switch, and the operation switch is activated to move the steps through the drive sprocket. A motor for driving the chain is assembled, and a worker mounted on the work trolley operates the operation switch so that the work trolley together with the step chain can be moved along the guide rail. This is achieved by carrying out the transportation and installation work of the parapet member using a handrail.

[Effect]

That is, according to the above means, a worker can ride a work cart driven along a guide rail to a working position, and the work cart can be equipped with parapet members such as an inner deck, an outer deck, and a skirt guard. Since the escalator can be transported in an efficient and safe manner, the escalator railing can be installed efficiently and safely.

5 is the drive and idler sprocket 2,
This step chain 15 is provided with front wheel roller shafts 14a corresponding to the number of steps.

Reference numeral 16 denotes a work cart placed and fixed on a predetermined number (nine in the figure) of the front wheel roller shafts 14a, and an operation switch 17 is attached to this work cart 16, and this operation switch 17 is connected to a cable 21.
It is connected to the control panel 11 via. That is, by operating the operation switch 17 by a worker on the work trolley 16, the low-speed motor 9 is started to drive the drive sprocket 2, and the step chain 15 and the front wheel roller shaft 1 are activated.
4a and the work trolley 16 to the guide rail 13.
It is now possible to move along the 18,1
Reference numeral 9 denotes columns erected at the upper and lower ends of the intermediate inclined portion 1c of the frame 1, and a wire 2 for supporting and guiding the cable 21 is installed between these columns 18 and 19.
0 is stretched, so that the cable 21 can follow the movement of the work cart 16.

In this way, the construction method according to the present invention uses the work cart 1.
6 is used, and the main installation work is performed in the order shown in FIG. 2, for example.

As shown in the figure, first, a machine base 4, a main motor 5, a reducer 6, a brake 7, and a drive sprocket 2 are installed in the upper horizontal part 1a of the frame 1.
In addition, the idler sprocket 3 is assembled in the lower horizontal part 1b in the factory, and these upper and lower horizontal parts 1a and 1b are transported and assembled together with the intermediate inclined part 1c to the installation site, and the frame 1 is centered and fixed ( Task 1). Next, the guide rail 12 is centered and fixed (work 2), and the front wheel roller 1 is
4 and a step chain 15 having a front wheel roller shaft 14a (operation 3). After these operations, the work cart 16 is assembled on the front wheel roller shaft 14a, and in parallel with this assembly operation, the low-speed motor 9, struts 18, 19, wires 20, emergency switches 12a, 12b, control panel 11, etc. The device is installed, and the control panel 11 and the operating switch 17 provided on the work trolley 16 are connected with a cable 21 (work 4). Then, a worker rides on the work trolley 16 and moves to the working position, or the assembled parts are mounted on the work trolley 16 and transported, thereby installing the parapet base (work 5) and installing the outer deck cover (work 5). A series of tasks including work 6), installation of the skirt guard base (work 7), wiring (work 8), installation of the handrail (work 9), installation of the skirt guard (work 10), and installation of the panel (work 11). do the work. After these operations are completed, the work trolley 16 and its related equipment are dismantled (operation 12).
Next, install the steps (work 13), install the inner deck cover (work 14), and install the main motor 5.
Perform trial run adjustment (work 15) and complete the installation work.

In addition, although the case where the low speed motor 9 was used in the above-mentioned embodiment was described, if the main motor 5 is capable of low speed driving operation, the low speed motor 9 may be used.
