As shown in FIG. 4, a slide plate 17a below the roller 9 and a slide plate 17b adjacent thereto are detachably fixed to the guide rail 4. The width of the divided slide plates 17a and 17b in the longitudinal direction is appropriately determined according to the diameter of the roller 9. When replacing the roller 9, the slide plate 17 is appropriately removed from the guide rail 4, and a gap is provided between the roller 9 and the guide rail 4 so that the roller 9 can be removed in the axial direction. The roller 9 may be replaced by removing the axle 9b, or replacing only the wheel 9a.

The slide plate 17 may have a divided structure only at the replacement location of the roller 9, and the other slide plates 17 may be integrally formed. Since the slide plate 17 which is not attached / detached by replacing the roller 9 does not need to be removed from the guide rail 4, it may be welded and attached. The procedure for removing the roller 9 will be described in detail below.

FIG. 5 is an explanatory diagram of a procedure for removing the roller 9 according to the present invention.
FIG. 5A: First, in order to eliminate the load applied to the slide plate 17a below the roller 9, the support beams 10 provided on both side surfaces of the movable head 6 are supported by an elevating device 12 such as a jack. The roller 9 does not need to be lifted beyond the height of the convex portion 16 of the slide plate 17, and the roller 9 can be replaced if the load of the movable head 6 is not applied to the slide plate 17a.

FIG. 5B: Next, the slide plate 17b adjacent to the slide plate 17a located below the roller 9 is removed from the guide rail 4.

FIG. 5 (c): Then, the slide plate 17a located below the roller 9 is moved to the position where the adjacent slide plate 17b was arranged. At this time, since the slide plate 17a does not exist below the roller 9, a gap is formed between the roller 9 and the guide rail 4, and the roller 9 can be removed in the axial direction.

When the replacement of the roller 9 is completed, the slide plate 17 is attached in the reverse procedure of the above procedure. In this embodiment, both sides of the movable head 6 are supported by the elevating device 12 to replace the roller 9, but only one side of the movable head 6 is supported by the elevating device 12 and the roller on the supported side is supported. 9 may be replaced. At this time, the ascending width of the elevating device 12 is set to a very small ascending width so that an unbalanced load is not applied to the roller 9 on the side not supported by the elevating device 12.

FIG. 6 is a front view of the elevating device according to the present invention.
In FIG. 6A, an elevating device 12 (jack) is installed on a pedestal 11 fixed to the side surface of the guide rail 4, and a support beam 10 fixed to the movable head 6 is supported by the jack 12.

Further, as shown in FIG. 6B, when supporting the movable head 6, a pedestal 11 having a flat upper portion and a valley-shaped recess formed in the lower portion is placed on the slide plate 17 on the guide rail 4. You may. The concave portion of the pedestal 11 is fitted with the convex portion 16 of the slide plate 17, and the jack 12 can be installed on the upper portion of the pedestal 11. By installing the jack 12 on the pedestal 11 and supporting the support beam 10 of the movable head 6 with the jack 12, the movable head 6 can be supported by the guide rail 4. The load of the movable head 6 is not applied to the slide plates 17 before and after the slide plate 17 on which the pedestal 11 is installed.

When the flat slide plate 17 is used, the jack 12 can be installed on the slide plate 17 without placing the pedestal 11.

In the above embodiment, the jack 12 is used to support the movable head 6, but by using the guide rail 4 of the present invention, the roller 9 can be used as the lifting device 12 even if the crane 12 whose lifting load is equal to or less than the load of the movable head 6 is used. Can be exchanged.

In a machine equipped with a filter press, especially in a small-scale machine, the lifting load of the crane 12 is equal to or less than the load of the movable head 6, so that the movable head 6 cannot be lifted by the crane 12 alone. However, by supporting only one support beam 10 on the side surface of the movable head 6 with the crane 12, the load can be dispersed and supported with the other roller 9. By setting the lifting width of the crane 12 to a very small lifting width so that an unbalanced load is not applied to the other roller 9, if the crane 12 corresponds to a load of 1/2 of the movable head 6, the movable head 6 can be used. I can support it. If the movable head 6 can be supported, the slide plate 17 can be removed and the roller 9 can be replaced in the same manner as in the above embodiment. When the replacement of one roller 9 is completed, the other support beam 10 is supported in the same manner as the one support beam 10, and the other roller 9 is replaced. As described above, even if the crane 12 has an upper limit of the lifting load equal to or less than the load of the movable head 6, the roller 9 can be easily replaced by providing the slide plate 17 of the present invention. Further, by combining the crane 12 and the jack 12, the movable head 6 can be supported from both side surfaces.
