Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an installation work device for an escalator,
In particular, the present invention relates to a working device suitable for installation work on the handrail portion of an escalator.

[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, large-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 the above-mentioned method were to be used to install the handrails of such high-floor escalators, workers would have to climb a long distance on scaffolding boards. the result,
Transporting the parts required a great deal of effort, resulting in poor efficiency and problems with work safety.

Accordingly, an object of the present invention is to provide an escalator installation work device that allows work to be performed efficiently and safely.

[Means for solving problems]

The above object is to provide a frame having an upper horizontal part and an intermediate inclined part between the lower horizontal part, a drive sprocket disposed in the upper horizontal part of the frame, and an idler sprocket disposed in the lower horizontal part of the frame. a step chain having a plurality of front wheel roller shafts wound between the drive sprocket and idler sprocket, a motor for driving the drive sprocket, and a step chain for guiding the step chain in the longitudinal direction of the frame. Assemble the guide rail that extends along the
In the escalator installation work device used for subsequent assembly of the balustrade member, the intermediate inclined portion is provided with an engagement member that straddles a plurality of the front wheel roller shafts and that engages with at least one of the front wheel roller shafts. A work cart is provided with a bottom frame having a section, a work floor supported by the bottom frame, and side plates erected around the work floor, and supports are provided at the upper and lower ends of the intermediate slope. A cable support is provided between these supports, while
A cable supported by the cable support body is provided between the driving panel of the motor and the work truck so as to follow the movement of the working truck, and the driving panel is connected to the work truck via the cable. This is achieved by providing an operating switch for controlling the work cart and moving the work cart together with the step chain.

[Effect]

That is, according to the above means, a worker can ride on a work cart driven along the inclined portion of the guide rail to a working position, and there is also an inner deck, an outer deck, a skirt guard, etc. inside the work cart. Since the parapet member can be loaded and transported, the installation work of the escalator's parapet can be carried out efficiently and safely.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, one embodiment of the escalator installation work apparatus according to the present invention will be described based on the drawings.

Figures 1 and 2 show how an escalator is being installed using the installation device according to this embodiment; Figure 1 is an overall side view; Figure 2 is an overall side view;
The figure is a detailed view of the main part of FIG. 1.

In these figures, 1 is a work cart, 2 is a frame, and this frame 2 is composed of an upper horizontal part 2a, a lower horizontal part 2b, and an intermediate inclined part 2c, and a drive sprocket 7 is installed in the upper horizontal part 2a.
However, idler sprockets 8 are disposed within the lower horizontal portion 2b. Between these drive and idler sprockets 7 and 8,
A step chain 9 equipped with front wheel roller shafts 15 corresponding to the number of steps is rolled up, and the drive sprocket 7 is connected to the motor 6 via the drive chain 10 and reduction gear 11. After the escalator is installed, This motor 6 drives a drive sprocket 7, which in turn drives a step chain 9. In other words, these constitute the drive mechanism section of the escalator. A guide rail 12 extends along the longitudinal direction of the frame 2 and guides the step chain 9. On this guide rail 12, a front wheel roller 21 supported by the front wheel roller shaft 15 can run. .

The work cart 1 has a predetermined number of front wheel roller shafts 15.
An operating switch 3 is mounted and fixed on the top, and this operating switch 3 is connected to the
It is connected to a driving panel 5 of a motor 6 provided within the upper horizontal portion 2a of the frame 2. Therefore,
By operating the operation switch 3, the motor 6
is activated to drive the drive sprocket 7, and the work cart 1 can be moved along the guide rail 12 together with the step chain 9 and the front wheel roller shaft 15. Incidentally, the cable 4 is connected to struts 13a and 13 erected at the upper and lower ends of the intermediate inclined portion 2c.
It is supported along a cable support 14 that connects the work cart 1 so that it can follow the movement of the work cart 1.

Next, the configuration of the work trolley 1 will be explained in more detail using FIG. 2. In the figure, an engaging portion, for example, a pawl 17 is fixed to the lower frame 16 of the work truck 1, and by engaging this pawl 17 with an arbitrary front wheel roller shaft 15, the work truck 1 can be moved. It is placed on a predetermined number of front wheel roller shafts 15. Further, a plurality of balustrades 19 are erected at the ends of the lower frame 16, and side plates 20 are attached between these balustrades 19.

Further, the working floor 1 supported by the bottom frame 16
8, as shown by breaking a part of the side plate 20, has a step-like structure and a horizontal part, which prevents the worker from slipping and the loaded parts from shifting. Can be done.

The work cart 1 is assembled after completing the assembly of the frame 2, the guide rail 12, the step chain 9, and other internal components of the frame.
Front wheel roller shaft 1 provided on step chain 9
It is done on 5. As described above, by operating the operation switch 3 attached to the work cart 1 to start the motor 6, the work cart 1 can be moved to a desired position along the inclined portion of the guide rail 12. Therefore, the worker can load the assembly parts onto the work cart 1, move to the work position, perform the assembly work there, and supply the necessary parts from the work cart 1.

By using the above-mentioned work cart 1 and moving it appropriately along the inclined part of the guide rail 12 or stopping it at the work position, the installation work of the escalator handrail part can be carried out efficiently. It can be done safely. Specifically, after assembling the frame 2 and frame internal equipment, assembling the work trolley 1 and its related equipment,
While using this work trolley 1, a series of tasks including attaching the balance column's external deck, attaching the hand frame, attaching the hand rail, wiring, attaching the skirt guard bracket, attaching the panel, and attaching the skirt guard. After completing these operations, the work cart 1 and its related equipment are removed, a step is attached to the front roller shaft 15, and an inner deck is attached.

It goes without saying that the configuration of the work cart 1 and the engagement structure between the work cart 1 and the front wheel roller shaft 15 are not limited to the one embodiment described above.

〔Effect of the invention〕

As explained above, according to the present invention, a work trolley is placed and fixed on the front wheel roller shaft, a worker can ride on this work trolley and move to a working position, and assembly parts can be mounted on this work trolley. Since the escalator can be transported by hand, worker fatigue can be significantly reduced and installation work can be carried out efficiently and safely, and this effect is particularly noticeable in the installation work of high-floor escalators.
