FIG. 4 shows the installation structure of the columns 3 and 4 described above.
~ Explaining with reference to FIG. 6, a column support plate 31 is fixed to the lower ends of the columns 3 and 4.
As shown in FIG. 6B, centering pin holes 32 of the same diameter are formed at two locations that coincide with the two centering pin holes 24 that are opened on the lower end surfaces of the columns 3 and 4, and this support is provided. Board 3
The centering pin 3 extends over the two centering pin holes 32 on the first side and the two centering pin holes 24 of the columns 3 and 4, respectively.
3 are closely fitted, and the relative positions of the support plates 31 and the columns 3 and 4 are regulated. In such a state, the lower end peripheral portions of the columns 3 and 4 and the support plate 31 are fixed by the angle member 34 arranged one for each side of the column. The horizontal plate portion 34 a of each angle member 34 has a bolt nut 35.
Is fixed to the support plate 31 by the vertical plate portion 3
4b is a groove 21a for member attachment of each of the columns 3 and 4
It is fastened with a bolt 37 to the tap plate 36 fitted to 21f.

A flange portion 33a is integrally provided at a central position in the lengthwise direction of the centering pin 33. Therefore, the peripheral edges of the opening ends of the centering pin holes 24 and 32 are connected to the collar portion 33.
By counterbore at a depth of about half of a, the centering pin 33 can be reliably fitted into both the centering pin holes 24 and 32 in equal amounts. Of course, it is also possible to counterbore only the opening edge periphery of either one of the centering pin holes 24, 32 with a depth corresponding to the thickness of the collar portion 33a. Further, the centering pin 33 can be fixed and protruded on the side of the support column 31 by an appropriate method.

In the pillar support plate 31, one through hole 3 is formed so as to open in the large-width groove rail portion 19 of the pillars 3 and 4.
8 are provided. As shown in FIG. 6A, as shown in FIG. 6A, elevating guide shafts 39 and 40 that fit into the through holes 38 are vertically fixed and projected at the standing positions of the columns 3 and 4, respectively. Through-holes 38 of the column support plate 31 fixed to the lower ends of the columns 3 and 4 on the lifting guide shafts 39 and 40.
Are fitted so that they can move up and down. Thus, the four corners of each support plate 31 are supported on the substrate 2 by the height adjusting bolts and nuts 41, as shown in FIGS. 5 and 6B.

The height adjusting bolts and nuts 41 are mounted on the substrate 2
A bolt 43 that is vertically screwed into a fixed nut 42 fixed to the column and penetrates through a through hole provided in the column support plate 31, and is screwed into the bolt 43 to vertically move the column support plate 31. It is composed of a plurality of nuts 44 that are clamped and fixed by the above. By adjusting the support plate clamping height by the nuts 44, the vertical height of the columns 3 and 4 can be finely adjusted.

The cross-sectional structure of the columns 3 and 4, the method of raising and lowering the raising and lowering carriage 5, the purpose of use of the raising and lowering carriage 5, and the method of tensioning the chain 11 for driving the raising and lowering carriage 5 and the counterweight 6 in an interlocking manner. The driving method and the like are not limited to the above embodiment. In addition, two lifting support devices of the two parallel column type shown in the above embodiment are installed side by side, and one guide rail and the object support means are supported by the two lifting carriages 5 to support a larger heavy load. It is also possible to configure an elevating / conveying device suitable for the object to be conveyed.

[0015]

As described above, according to the present invention,
The elevating carriage guide column and the column support plate attached to the lower end of the column are accurately positioned with each other by fitting at least two centering pins and centering pin holes. Positioning of the column support plate with respect to the substrate fixed by a hole-in anchor or the like on the floor surface is accurately performed by an elevating guide shaft protruding from the substrate penetrating the column support plate. Therefore, if the accuracy of the protruding position of the centering pin with respect to the support column, the processing position of the hole through which the lifting guide shaft penetrates, and the accuracy of the protruding position of the lifting guide shaft with respect to the substrate are increased, It is possible to sufficiently enhance the positional accuracy of the lifting and lowering carriage guide columns with respect to the.

Therefore, particularly when two columns for guiding one lifting carriage are erected on one substrate with the above structure, the accuracy of the relative positional relationship between the two columns can be increased, and The elevating operation of one elevating carriage guided by the two columns can be smoothly and favorably performed.

Moreover, fine adjustment of the height and verticality of the support column
Of course, it can be easily done as usual with a plurality of height adjusting bolts and nuts that support the periphery of the support column,
At the time of attaching the support column to the lower end of the column, the column support plate is positioned at the lower end of the column by the centering pin, so that the connection work between the two can be performed easily, and the column support plate moves up and down with respect to the board side. Since it is positioned by the shaft, the work of supporting the column support plate on the substrate by the plurality of height adjusting bolts and nuts can be easily performed.
