Therefore, even when the fixed duct 97 is deformed, each lower guide member 321 can be prevented from damaging the fixed duct 97 and the seal belt 98.

  Moreover, when the moving body 2 is stopped, the displacement means 4 displaces the apparatus main body 31 downward with respect to the moving body 2 so that each lower guide member 321 is separated from the fixed duct 97 by a predetermined amount or more. Can be prevented. Therefore, even when the fixed duct 97 is deformed, the sealing belt 98 can maintain the performance of sealing the opening 971 of the fixed duct 97, so that the dust-containing gas collected by the moving body 2 is sent through the fixed duct 97. At this time, it is possible to prevent the dust-containing gas from leaking out between the fixed duct 97 and the seal belt 98 in the vicinity of each lower guide member 321.

  Further, according to the coke guide wheel (moving device) 1 and the belt lifting device 3 according to the present embodiment, the connection port 342 connected to the opening 971 of the fixed duct 97 has a plurality of abutments along the periphery. The members 342a,... Are arranged in parallel. Even when the fixed duct 97 is partially deformed, each contact member 342a can be individually deformed by coming into contact with the fixed duct 97, so that each contact member 342a according to the deformation of the fixed duct 97. Is deformed.

  Therefore, since the apparatus main body 31 is positioned at the lower limit position, each contact member 342a can reliably contact the fixed duct 97, and the connection duct 34 can seal the opening 971 of the fixed duct 97. Thereby, when the dust-containing gas collected by the mobile body 2 is sent through the connection duct 34 and the fixed duct 97, the dust-containing gas can be prevented from leaking between the connection duct 34 and the fixed duct 97. .

  Further, according to the cork guide wheel (moving device) 1 according to the present embodiment, the contact / separation member 42 of the displacing means 4 comes into contact with the device main body 31 from the lower side and pushes up, so that the device main body 31 rises and the upper limit At each position, the lowering restricting portions 314 and the fixed duct 97 are separated from each other. On the other hand, since the apparatus main body 31 is connected to the moving body 2 through the connecting means 33 so that the apparatus main body 31 can be lowered by its own weight, the apparatus main body 31 is moved as the contact / separation member 42 moves downward. Descend.

  When the lowering restricting portions 314 provided in the lower part of the apparatus main body 31 come into contact with the fixed duct 97, the lowering of the apparatus main body 31 is restricted, and thereafter, the contact / separation member 42 moves further downward. Accordingly, the apparatus main body 31 and the contacting / separating member 42 are separated from each other. Accordingly, since the lower limit position of the apparatus main body 31 is set at a position where each lowering restricting portion 314 comes into contact with the fixed duct 97, each lower guide member 321 is set at a suitable position corresponding to various deformations of the fixed duct 97. Can be located.

For example, the displacement means may be configured to include a drive source composed of a motor and a gear mechanism that converts the drive of the drive source into an acting force in the vertical direction and transmits it to the apparatus main body 31. In short, the displacing means may be configured to move up and down the apparatus main body 31 by being connected to the apparatus main body 31 and moving up and down, or by moving to and away from the apparatus main body 31 from below.

  Further, in the moving device 1 and the belt lifting device 3 according to the above-described embodiment, the configuration has been described in which each contact member 342a of the connection port portion 342 is deformed by contacting the fixed duct 97, but the configuration is not limited thereto. Instead, the structure may be such that each contact member is displaced by contacting the fixed duct 97. Specific examples of such a configuration are shown in FIGS. 9 and 10, respectively.

  As for each contact member 343a of the connection port part 343 shown in FIG. 9, the base end part is attached to the duct main body 341 so that rotation is possible. Specifically, each contact member 343a is attached to the duct main body 341 via a hinge member 343b. Then, as shown in FIG. 9A, the apparatus main body 31 is in the upper limit position, and as shown in FIG. 9B, the apparatus main body 31 is in the lower limit position. As a result, the tip of each contact member 343a contacts the fixed duct 97, and thus each contact member 343a is rotationally displaced individually with respect to the duct body 341.

  Each contact member 344a of the connection port portion 344 shown in FIG. 10 is attached to the duct body 341 so as to be slidable in the vertical direction. Then, as shown in FIG. 10A, the apparatus main body 31 is in the upper limit position, and as shown in FIG. 10B, the apparatus main body 31 is in the lower limit position. As a result, the tip end portion of the contact member 344 a contacts the fixed duct 97, so that each contact member 344 a is displaced upward with respect to the duct body 341.
