Abstract

(57) [Abstract] [Purpose] To provide a shutter structure of a rail traveling carriage device capable of improving the airtightness of a dustproof and fireproof compartment. [Structure] A structure of a shutter crossing portion of a rail traveling vehicle device, wherein traveling rails crossing the shutter 4 are divided and arranged with the shutter 4 interposed therebetween.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a shutter structure of a rail traveling carriage device installed in a factory or a warehouse. In particular, the present invention relates to a shutter structure of a rail traveling carriage device capable of improving the hermeticity of a shutter at a transverse portion such as a dustproof fireproof shutter.

[0002]

[Prior Art]

 2 (a) and 2 (b) are a front view and a left side sectional view showing a shutter structure of a conventional rail traveling carriage device.

In FIG. 1, R is a traveling rail laid on the floor FL of the building, and 1 is a rail traveling carriage that travels on the traveling rail R with four wheels 2. Each wheel 2 of the rail traveling vehicle 1 is provided with a guide wheel 2a for guiding the wheel. Reference numeral 3 denotes a dustproof and fireproof section installed in a building or the like, and a shutter 4 is provided at an entrance / exit G of the rail traveling vehicle 1. The shutter 4 is moved up and down by a winding mechanism 4a provided at the upper part of the entrance / exit G, and when it is lowered, the lower end 4b comes down on the traveling rail R.

Reference numeral 5 denotes a rising portion which is erected on the floor surface FL of the entrance / exit G and is formed of a member such as an iron plate or concrete. As shown in FIG. 2 (a), the rising portion 5 is raised to the level of the traveling rail R, and when the shutter 4 is closed, it closes between the shutter 4 and the floor surface FL. ing. Reference numeral 6 denotes a guide wheel passage groove formed in the rising portion 5 so that the guide wheel 2a does not interfere with the rising portion 5 when the rail traveling carriage 1 passes.

[0005]

[Problems to be solved by the device]

 The shutter structure in the conventional rail traveling carriage device described above has the following problems.

A groove 6 for passing the guide wheel 2a had to be formed in the rising portion 5. For this reason, even if the fireproof shutter 3 is lowered onto the traveling rail R to close the entrance / exit G, the respective grooves 6 are still open, and the airtightness in the dustproof / fireproof compartment cannot be improved. was there.

An object of the present invention is to provide a shutter structure for a rail traveling carriage device that solves the above-mentioned conventional problems and can enhance the airtightness of a dustproof fireproof compartment or the like.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is a structure of a shutter crossing portion of a rail traveling carriage apparatus, in which a traveling rail crossing the shutter is arranged with the shutter separated.

[0009]

[Operation effect]

 Since the present invention has the above-mentioned configuration, it has the following operational effects.

That is, since the traveling rails that traverse the shutters are arranged with the shutters separated from each other, when the shutters are lowered, the shutters can be lowered to the floor surface.

As described above, according to the shutter structure of the rail traveling bogie device of the present invention, there is an effect that it is possible to enhance the airtightness of the dustproof fireproof zone and the like.

【Example】

 Hereinafter, the illustrated embodiment will be described.

1 (a) and 1 (b) are a front view and a left sectional view showing a shutter structure of a rail traveling vehicle apparatus according to the present invention. The same parts as those shown in FIGS. 2A and 2B are designated by the same reference numerals.

As shown in FIG. 1B, in the rail traveling vehicle apparatus of this embodiment, a traveling rail that crosses the shutter 4 is divided into a traveling rail R1 and a traveling rail R2 with the shutter 4 interposed therebetween. It is arranged. The distance L between the traveling rail R1 and the traveling rail R2 is set in consideration of the thickness of the shutter 4 as shown in the figure, and when the shutter 4 descends, the traveling rails R1 and R2. The shutter 4 is so narrow that it does not interfere with it. By thus disposing the traveling rail R1 and the traveling rail R2 separately, when the winding mechanism 4a of the shutter 4 is operated and the shutter 4 is lowered, the lower end 4b of the shutter 4 travels with the traveling rail R1. It will come down on the floor surface FL through the rail R2.

As a rail traveling vehicle for traveling on the traveling rails R1 and R2, a rail traveling vehicle 11 having a pair of wheels 10, 10 as shown in FIG. 1 is preferable. Is. When such a rail traveling carriage 11 passes through a part where the traveling rail R1 and the traveling rail R2 are divided, the pair of wheels 10 and 10 can suppress the vibration lower than that of one wheel, so that the traveling traveling vehicle 11 can be Improves stability.

According to the above-described shutter structure of the rail traveling vehicle device, the traveling rail that crosses the shutter 4 is divided into the traveling rail R1 and the traveling rail R2 with the shutter 4 interposed therebetween. It is possible to lower the lower end 4b of the above to the floor surface FL, and it is possible to enhance the airtightness of the dustproof fireproof compartment and the like.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, but can be appropriately modified and implemented within the scope of the gist of the present invention.

For example, each wheel of the rail traveling carriage does not necessarily have to be provided in pairs, and may be one wheel.
