DETAILED DESCRIPTION OF THE INVENTION
(Overall configuration)
FIG. 1 shows a state where the lifting and polishing apparatus 1 is erected on an anchor base 2 that is installed at a predetermined position in the island and whose upper surface is horizontally installed. The lift polishing apparatus 1 is substantially the same as that described in the prior art example, and is configured by a peripheral member 4 and a drive motor 5 provided on a base member 3 fixed on the anchor base 2. It is. On the surrounding box 4, a lifting tower 6 containing a spiral body and the like is erected. The base member 3 (lifting and polishing apparatus 1) is fixed on the anchor base 2 by being engraved in the through holes 3c,... Provided in the flange portions 3b, 3b projecting on both sides of the base member, and the anchor base. Further, the fixing bolts 7 are respectively screwed and tightened to the female screw portions 2d,... (See FIGS. 2 and 3).
[001 0 ]
As shown in FIG. 2, the anchor base 2 has a main body 2a having a rectangular shape whose depth is slightly larger than the frontage and a flat upper surface, and a locking member 2b attached to the rear end of the main body so as to be swingable. It is comprised by. On the upper surface of the main body 2a, rail portions 2c, 2c made of two parallel groove portions are provided so as to be vertically cut. Further, female screw portions 2d,... That can be screwed with the fixing bolt 7 described above are engraved on the outer sides of the rail portions 2c, 2c. The anchor base body 2a is made of an aluminum cast or cast iron product in addition to a plastic molded product.
[001 1 ]
(Configuration of base member)
FIG. 3 shows a procedure for installing the lifting and polishing apparatus 1 on the anchor base 2. The configuration of the base member 3 will be described before the installation procedure is described. The main body 3a of the base member 3 is composed of a container body having an opening at the lower portion, and the flange portions 3b and 3b described above are formed on both side portions, and through holes 3c are formed at respective predetermined positions. Become. The upper surface 3d of the main body of the base member 3 is finished flat, and the above-described peripheral box 4 and drive motor 5 are mounted thereon.

Casters 8,... Are attached to the four corners of the base member main body 3a. Each of the casters 8 bears the weight of the lift polishing apparatus 1 via a compression spring 9. The support column 8a of the caster 8 can be moved up and down by passing through a support member 3e fixed to the wall portion of the main body. Each compression spring 9 is between the caster frame 8b and the support member 3e, and elastically supports the base member 3, respectively. For this reason, when the base member 3 is moved onto the anchor base 2, the compression spring 9 floats and a gap C is generated between the lower portion of the base member and the upper surface of the anchor base 2. Can be moved by making it rotatable.
[001 3 ]
(Installation method of lifting polishing equipment)
Prior to installing the lifting and polishing apparatus 1 in the island, first, the anchor base 2 is fixed at a predetermined position in the island so that the rail portions 2c and 2c are orthogonal to the passage. At this time, it is important to fix the upper surface of the anchor base body 2a so as to be in an accurate horizontal state (first step).
[001 4 ]
Next, the caster wheel 8c is moved to the vicinity of the anchor base 2 using the casters 8, in a state where the lift polishing apparatus 1 is mounted on the base member, and each caster wheel 8c is pushed to a predetermined position in accordance with the rail portion 2c of the anchor base ( Second step). At this time, since the caster wheel 8c is placed in the recess of the rail portion 2c, the gap C between the lower portion of the base member 3 and the upper surface of the anchor base is small, but the upper surface of the anchor base body 2a is Since it is flat, there is no hindrance to movement.
[001 5 ]
When the tip of the base member 3 reaches the tip of the anchor base 2, a force is applied so as to push the upper part of the lifting tower 6 (see FIG. 1) forward, as shown in FIG. 3 (b). Then, the lower end portion of the base member 3 is pressed against the upper surface of the anchor base 2 to sink the distal end portion. Thus, when the tip portion is in a sunk state, the hook portion formed at the upper end of the locking member 2b is locked to the tip portion of the upper surface of the base member, so that it cannot float.
[00 16 ]
Next, the lifting tower 6 that has been slightly inclined is returned to the passage side, the front side of the base member 3 is lowered, and the fixing bolt 7 is screwed into the female thread portion 2d from the through hole 3c and tightened (third step). By tightening the fixing bolt 7, the base member 3 (lifting polishing apparatus 1) descends against the spring force of the compression spring 9, and the lower part is in close contact with the upper surface of the anchor base 2. The entry of dust etc. is lost.
[00 17 ]
In the description of this embodiment, it is assumed that a spiral type lift polishing apparatus is installed. However, the present invention is not limited to this, and other types of lift polishing apparatus and other devices are used. It can also be applied to installation.
[00 18 ]
【The invention's effect】
According to the present invention, it is very easy to install the lifting and polishing apparatus, and a gap between the lower portion of the base member and the upper surface of the anchor base is not generated, so that entry of dust and the like can be eliminated.
