It is hanging .

[0019] The lower end of Tsu支belt (14), bed (16) is connected.

Next, the fall prevention device (52) will be described with reference to FIGS. The fall prevention device (52) is provided between the drive unit (8) and the current collection unit (10) on the upper surface of the top plate (56) of the transfer device main body (12). straight
It has a guide rail (54) mounted crosswise.

As shown in FIG. 2, the cross section of the guide rail (54) is such that the upper part (58) has an I-shape wider than the lower part (60).
I have.

The fall prevention device (52) comprises a hook (61), this
Of the first holding portion (62) having a U-shape in side view.
And project horizontally from the upper end of the upward facing piece
With a locking piece (63) that extends out, on the rear side of the first holding portion (62).
The facing piece is a support piece (64).

The locking piece (63), the lower the water transport rail (2)
It is located slightly above the upper surface (3) of the flat piece.

The front surface of the support piece (64) and (65), a locking piece (63)
The distance between the rear end (66) is shorter than the longitudinal width <br/> of the vertical portion of the conveying rail (2).

[0025] Under surface of the locking piece (63) (67), the transport rail (2)
Per the upper surface of the horizontal portion (3), and even when the locking piece (63) is closest to the transfer rail (2), the support piece (64)
Front side (65) abuts against the side surface (5) extending <br/> beauty Ru suspended piece from downward (68) of the transport rail (2), the hook (61) transfer rail
So as not to come out of (2), it is set a positional relationship of the locking piece (63) and the support piece (64).

[0026] The hook (61), both sides of the transport rail (2)
(5) A pair of horizontal guide rollers at the position facing (5)
(72) (72) is provided.

[0027] In addition to the hook (61), guide rail (54)
Second embracing portion to wrap so as not come off the has (74). The cross-sectional shape of the second embracing portion (74), as shown in FIG. 2, so that the wrap wide upper portion of the guide rail (54) and (58)
And it has a shape.

The second embracing portion (74) includes a plurality of balls is disposed, in particular the ball hits the guide rail (54)
Ri, hook (61) will then lightly move the guide rail (54) on
It is so.

Next, the operation will be described. This hanging transfer device (1) is used, for example, as shown in FIG.
You.

As shown in FIG. 5 , the hanging transfer device (1)
After moving along the transfer rail (2), Tsu支belt (1

In this case, the hanging conveyor device (1), the unit and not out of the other, while being supported by only the like of the end portion of the conveyor device main body (12), that is, 1 point support.

However, in such a case, the hook (61)
Second embracing portion (74), and engaging the conveyor device main body (12) and integral with the guide rail (54), also the first embracing portion of the hook (61) of
(62), by the locking to Rukoto the transport rail (2), the fall prevention device (52), conveying device main body (12) transfer rail
(2) It will be supported above .

[0034] Thus, 2 of only the end portion or the like of the unit and the conveying apparatus body not out of the other (12), first the embracing portion (62)
At several places, the suspended transport device (1) is in a supported state.

[0035] Therefore, goods and parts and the like on the loading platform unit (16), or fall from bed (16), through the Tsu支belt (14)
Te bed (16) is prevented from swinging or rather large safety hanging conveyor device (1) increases.

In the above-described embodiment, the suspension transport device (1) used in a warehouse or a factory has been described. However, the suspension device according to the present invention is a suspension transport device as a means of transporting people. For example, the present invention can be used for various hanging conveyance devices.

[0037]

The upper surface of the Effects of the Invention] suspension conveying device, the guide rails provided toward a right angle <br/> the conveying direction, the first embracing portion which surrounds so as not exit the transport rail, on both sides of the transport rail Department
And a pair of guide rollers opposite, since is provided a fall-prevention device with the hook <br/> Ru provided with a second embracing portion to wrap so as not come off the guide rail, the conveyor apparatus hanging Falling is prevented, and the safety of the suspended transfer device is improved.

The fall prevention device travels on a transport rail.
Drive unit and, a current collector uni <br/> Tsu you want to travel on the transfer rail, a transport device body hung is rotatably supported by the both units, Ri winding from conveyor device main body to the lower及<br/> beauty and feeding capable Tsu支provided belt, is applied to hanging conveying device that includes a loading platform which is attached to the lower end of Tsu支belt, the guide rails, put between the both units
Since the transport device is provided integrally with the top plate of the body that, even when the two-point support of the conveyor device main body has become one point supported by accident, immediately is supported on conveying apparatus main body conveyance rails by anti-fall device Re I Do to Rukoto, two-point support is maintained, resulting in one-point support, and have largely inclined is bed that is suspended by Tsu支belt, dropping of parts or the like on the loading platform, is bed Tsu支it as rocking larger by the belt is prevented.
