[0028]
The detecting device 1a such as a laser pointer installed on the carriage 1 detects the marking position drawn on the floor surface, and the carriage 1 moves below the anchor mounting position of the ceiling slab, and the monitoring means (not shown) Then, confirm the anchor attachment position 8 of the ceiling slab and stop the carriage 1.
[0029]
When this device is used, the support base 3 is moved upward on the pillar 2 by the adjusting device 2a, and when the stopper 24 comes into contact with the ceiling slab, the upward motion is stopped.
[0030]
Next, the drill device 7 is moved up by the upward movement of the lifting device 10 on the support base 3, and the drill 9 is inserted into the drill hole 6 a of the disk 6 to drill the anchor attachment hole 8 in the ceiling slab. . Then, the elevating device 10 is moved down to move the drill device 7 down, and the disk 3 previously loaded with the anchor is also rotated intermittently by intermittent rotation of the motor 26, so that the anchor loading hole 6b is formed. The anchor mounting hole 8 is moved to a position immediately below the anchor mounting hole 8, and the turn mounting base 11 is intermittently rotated by intermittent rotation of the motor 11b to move the anchor driving device 12 to a position immediately below the anchor mounting hole 8 drilled in the ceiling slab. Move. Next, the lifting / lowering device 15 is moved up to move the anchor driving device 12 up, and the anchor driving member 14 is inserted into the anchor loading hole 6b to hold the anchor 13 while holding the anchor mounting hole 8. The anchor 13 is driven into.
[0031]
When all the anchors 13 loaded in the anchor loading hole 6b have been hit, the adjusting device 2a is moved down to load the anchor into the anchor loading hole 6b again.
[0032]
Another embodiment different from the above is shown in FIG. Although this embodiment is basically different from the above-described embodiment, a support ring 37 is used as a means for supporting the flexible tube 17, and the support ring 37 is connected to the frame member via an arm 38. 5 is fixed to the inner surface of the flange portion 5b, and the support ring 37 supports the enlarged tip portion 17b of the flexible tube 17 so that the enlarged tip portion 17b is disposed below the opening 16.
[0033]
In this embodiment, the enlarged tip portion 17b is brought into contact with the peripheral portion of the opening 16 on the lower surface of the disc 6 so that no gap is generated between the enlarged tip portion 17b and the disc 6. The forced dust recovery operation by suction from the provided forced dust recovery device 18 is not hindered.
[0034]
In this embodiment, the drill 9 of the drill device 7 provided on the turntable 11 and the anchor driving member 14 of the anchor driving device 12 are not contacted with the arm 38 when the turntable 11 rotates. As shown in FIG. 6, the struts 4 and 4 are configured to be sufficiently long so that the moving distance of the rods 29 and 30 is sufficiently large.
[0035]
【The invention's effect】
The anchor mounting apparatus according to claim 1, wherein the drilling operation and the anchor driving operation are alternately performed, and the anchor mounting by drilling the ceiling slab while intermittently rotating a disk loaded with a large number of anchors in advance. Since the anchor is driven into the hole, as long as the anchor is loaded in the anchor loading hole, the drilling operation and the anchor driving operation can be performed continuously, improving the work efficiency and reducing the cost. Have.
[0036]
In addition, since the two tools of the drill and the anchor driving member are driven by separate driving devices, it is not necessary to change the tool, and an optimal driving device can be used for both operations.
[0037]
Further, by using this anchor mounting device, the operator is not forced to perform a difficult work at a high place.
[0038]
In the anchor mounting device according to claim 2, since the opening for collecting dust is provided in the vicinity of the hole for drilling the disc, the forced dust collecting device is not only during the operation of the drilling device but also immediately after that. Since driving prevents dust from falling from the overhead of the worker, the working environment can be greatly improved as compared with the prior art.
