It does not hinder the forced dust collection operation.

In this embodiment, the drill 9 of the drill device 7 provided on the turntable and the anchor driving member 14 of the anchor driving device 12 do not hit the arm 38 when the turntable 11 rotates. In addition, as shown in FIG. 6, the columns 4 and 4 are configured to be sufficiently long so that the rods 29 and 30 have a sufficient downward movement distance.

[0035]

According to the anchor mounting device of the first aspect, the drilling operation and the anchor driving operation are performed alternately.
An intermittent rotation of a disk loaded with a number of anchors beforehand drives the anchors into the anchor mounting holes drilled in the ceiling slab, so drilling work is performed as long as the anchors are loaded in the anchor loading holes. And anchor driving work can be performed continuously, work efficiency is improved,
This has the effect of reducing costs.

Also, since the two tools, the drill and the anchor driving member, are driven by separate driving devices,
There is no need to change tools, and an optimal drive device can be used for both operations.

Further, by using the anchor mounting device, the operator is not forced to perform difficult work at high places.

[0038] In the anchor mounting device according to the second aspect of the present invention, since the opening for dust collection is provided near the drill hole of the disk, the forced dust is not only provided during the operation of the drill device but also immediately thereafter. Since the collection device is operated to prevent dust from falling from above the worker's head, there is an effect that the working environment can be greatly improved as compared with the related art.
