The lower surface of the falling object guide member 30 is supported by this. In addition, the buffer seating portion 65 is not coupled to the lower surface of the drop guide member 30, but is supported elastically, but not limited to this, it will be appreciated in advance that can be combined.

Here, the connecting members (67a) (67b) (67c) in the case of the cylinder structure of the shock absorber (Shock absorber) type there is a convenience in use that does not need to adjust the height of the third vertical strut bar 61. In addition, the connecting members 67a, 67b and 67c are cylinders which are operated by hydraulic circuits, respectively, and the falling object guide member 30 is developed in the state of FIG. 1 or separately separated to the fixed H beam 20 direction. Although it is configured to be divided and folded, detailed hydraulic circuits thereof will be omitted since it is a well-known technique.

The operation of the anti-falling device 100 for a perforator according to the present invention will now be described.

First, the drilling equipment 200 is placed at a place where drilling is to be performed. After that, the stationary column 300 and the auger screw 400 stand up to complete drilling preparation.

Then, by installing the falling object prevention safety device 100 for drilling machine according to the present invention, as shown in FIG.

Thereafter, when the Auger screw 400 penetrates the ground and starts to perforate by operating the Civil Punch device 200, dirt or gravel rises along the Auger screw 400, And falls vertically at the adjacent portion.

Here, the falling object falling vertically is concentrated on the falling object conveying plate 31 along the falling object guide 33 inclined in the respective inward direction of the falling object guide member 30 of the present invention, the pulley of the final falling object conveying plate 31 It is conveyed in the direction of 31d and then dropped vertically to be dumped. At this time, the fall where the falling object is a point away from the drilling area, even if the worker is located at the drilling point to understand and conduct the drilling process, the safety accident is never caused by the falling object.

When the drilling operation is completed, the operation of the civil drilling equipment 200 is stopped and thereafter by operating the connecting members 67a, 67b, 67c of the drop guide support member 60 to separate the drop guide member 30 Respectively folded in the direction of the fixed H beam (30).

Finally, when the falling safety device 100 for a perforator of the present invention is detached from the civil engineering drilling equipment 200, all operations are completed.

Here, the operational relationship of the present invention is limited to the case where the safety device 100 for preventing falling objects for perforators is installed or removed from the civil engineering drilling equipment 200, but the present invention is not limited to this, and the built- It is possible to know in advance.
