Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator installation work device, and more particularly to an escalator installation work device for installing a balustrade while moving an intermediate inclined portion by a work carriage.

[0002]

2. Description of the Related Art Conventionally, in the work of installing a balustrade of an escalator, after the installation of a frame, a guide rail, and a device inside the frame such as a step chain is completed, a plate is mounted on the other front wheel roller shafts provided on the step chain. Was used to transport and install balustrade members while using this board as a work scaffold. However,
In recent years, the number of escalators on high floors, which has been rapidly increasing in number, may reach a floor height of 20 m and a slope distance of 40 m. Members must climb and descend the scaffold a long distance. As a result, it takes a lot of labor to transport the members, which is inefficient and has a problem in work safety. Therefore, as one means for solving these problems, for example, an installation work device for an escalator described in Japanese Patent Laid-Open No. 62-212187 has a work carriage mounted on the front wheel roller shaft of a step chain, and this work carriage is operated at a low speed. The balustrade member is transported and attached while being moved by the device, thereby reducing the number of scaffolding plates and labor.

[0003]

By the way, in the above-mentioned conventional installation work device for an escalator, no consideration is given to the method of installing the work carriage, and since all the work carriages are assembled by the temporary members, the temporary work equipment is temporarily installed. There is a problem that the number of members increases. As a result, it takes time to remove the work truck after the installation work is completed,
Further, the cost of the temporary member for the work carriage is increased.

The present invention has been made in view of the actual situation in the prior art as described above, and an object thereof is to provide an escalator installation work device capable of reducing the number of temporary members required for a work carriage. is there.

[0005]

In order to achieve this object, the present invention has a work carriage provided on a front wheel roller shaft of an escalator and driven by the front wheel roller shaft. In an installation work device for an escalator, which carries out installation work of a balustrade while moving an intermediate inclined part, the work carriage is provided with a predetermined number of steps for main installation to be mounted on the front wheel roller shaft, and to cover these main installation steps. The work floor is mounted and fixed on the work floor, and the frame body is detachably held on the work floor.

[0006]

Since the present invention is configured as described above, the work carriage used when performing the balustrade installation work is to install a predetermined number of steps for main installation on the front wheel roller shaft, and then to install these main installation steps. It is formed by placing and fixing the work floor on the step and fixing the frame body to the work floor. by this,
Since the main installation step is used as the base member of the work carriage, the temporary base member is unnecessary, that is, the number of temporary members required for the work carriage can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an escalator installation work device according to the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view showing an embodiment of an installation work device for an escalator of the present invention,
2 is a side view showing a portion of a work cart provided in the installation work apparatus of FIG. 1, and FIG. 3 is a side view showing a state in which a work floor provided in the installation work apparatus of FIG. 1 is fixed.

The escalator of this embodiment shown in FIG. 1 has an upper horizontal portion 1a, a lower horizontal portion 1b, and an intermediate inclined portion 1c.
A frame 1, a drive sprocket 2 disposed in the upper horizontal portion 1a, an idler sprocket 3 disposed in the lower horizontal portion 1b, and a drive sprocket 2 and an idler sprocket 3, respectively. A step chain 5 having a front wheel roller shaft 4, a motor 8 connected to the drive sprocket 2 via a drive chain 6 and a speed reducer 7, and a control device 9 for controlling the drive of the motor 8.
And a brake 10 installed between the motor 8 and the speed reducer 7.
And a guide rail 11 extending along the longitudinal direction of the frame 1 for guiding the step chain 5, and a front wheel roller 12 supported by the front wheel roller shaft 4 and capable of traveling on the guide rail 11. ..

The escalator installation work device according to the present embodiment is provided on a work carriage 13 which will be described later, and includes a control device 9
An operation panel 14 including a transmitter (not shown) that outputs an operation signal for operating the receiver, a receiver 9a that is included in the controller 9 and receives the operation signal, the controller 9 and the power cable 1.
And a low speed operation device 16 that outputs a variable frequency and a variable voltage.

As shown in FIG. 2, the work carriage 13 described above is mounted and fixed so as to cover a predetermined number of steps 17 for main installation, which are attached to the front wheel roller shaft 4, and these steps 17 for main installation. Working floor 18 and this working floor 18
And a frame body 19 which is detachably held. Further, as shown in FIG. 3, the work floor 18 is fastened and fixed to the step fixing portion 4a of the front wheel roller shaft 4 together with the uppermost step 17a for main installation by the mounting bolt 20, and as shown in FIG. 18a and frame fixing part 1
8b.

In this embodiment, when the balustrade is installed, a predetermined number of steps 17 for main installation on the front wheel roller shaft 4 and a work floor 18 placed on these steps 17 for main installation. Are fixed together by mounting bolts 20, and then the frame body 19 is fixed to the frame body fixing portion 18b of the work floor 18. After forming the work carriage 13 in this manner, the worker operates the operation panel 14 provided on the work carriage 13 to output an operation signal through the transmitter. This operation signal is input to the control device 9 via the receiver 9a, and then the control device 9 controls the drive of the motor 8 via the low speed operation device 16 according to the operation signal to drive the work carriage 13. .. The worker carries the balustrade member by the work carriage 13 and carries out the installation work.

In the embodiment constructed as described above, since the main installation step 17 is used as the base member of the work carriage 13, the base member for temporary construction is unnecessary, that is, the number of temporary construction members required for the work carriage 13 is increased. Can be reduced. Further, since the work floor 18 is placed and fixed so as to cover the main installation step 17, the work can be performed without damaging the main installation step 17.

In this embodiment, the upper part of the work floor 18 is fastened and fixed together with the main installation step 17a. However, the present invention is not limited to this, and the lower part of the work floor 18 may be fastened and fixed by the same method. Good. Also, if there is a caution advisory member to prevent the skirt guard from being caught between the steps on both sides of the upper surface of the main installation step, remove this caution advisory member and fix the work floor to the caution advisory member attachment part. You may do so. Further, in this embodiment, the work floor 18
Although it is integrally formed, it may be divided and, for example, one working floor may be provided for each main installation step.

[0014]

Since the present invention is configured as described above, it is possible to reduce the number of temporary members required for the work carriage as compared with the prior art, and thereby to efficiently perform the work for removing the work carriage. It is also possible to reduce the cost of the temporary member.
