生することがあつた。 In a drilling pole construction vehicle in which the drilling machine is suspended from a bracket that is selectively locked to the outer boom or inner boom of the telescopic boom, when the telescopic boom is completely retracted, the boom or the stay fixed to the boom is Hook the cable with one end fixed to the drill of the drilling machine, rotate the drill to wind the cable around the drill, and hook the drill to the stay fixed to the side or bottom of the outer boom to dig the hole. If you store the drilling machine without completely retracting the boom, the drill will not enter the stay properly and the drill will hit the outer periphery of the stay, causing excessive tension on the cable. In some cases, accidents occurred where the cables were damaged.

て警報装置１３を作動する。 Embodiments of the present invention will be described below with reference to the drawings. Fig. 1 shows the state in which the excavator of the excavator and pole erector is being stored, and the turntable 2 is placed on the car body 1.
Telescopic booms 3 and 4 are pivotally supported, and a hole digging machine A is suspended from a bracket 5 fitted to the inner boom 4 via a link 6. A stay 9 for storing a hole digging machine is fixed to the side of the outer boom 3,
One end of the cable 10 is fixed to the stay 9, and the other end of the cable 10 is hooked to a hook fixed to the outer periphery of a drill 8 of the drilling machine A, and the cable 10 is wound around the drill 8 as the drill 8 rotates. As shown in FIG. 2, a tension sensing switch 11 is provided at the attachment point of the cable 10 of the stay 9, and if the position of the drill 8 is not correct and the collar 8' of the drill 8 hits the stay 9, the tension sensing switch 11 is installed. When a tension exceeding a certain value is applied to the cable, the tension sensing switch 11 is turned on and the alarm device 13 is activated by the electric circuit shown in FIG.

オフ弁１４を切換え、穴掘機の駆動を停止する。 FIG. 5 shows another embodiment, in which a shut-off valve 14 is attached to the stay 9, and as shown in FIG. It is inserted into the circuit that connects the In addition, this shut-off valve 14
is provided with actuators 14' and 14'' in the vertical direction, respectively, and when the drill 8 properly enters the stay 9 and reaches the upper limit position, the drill 8 moves to the lower actuator 1.
4' to switch the shut-off valve 14 and stop driving the drill 8. Upper actuator 14″
is pivotally attached to the other end of the link 15, one end of which is pivoted to a bracket 21 attached to the stay, and a spring 2 is pivoted to the bracket 21 coaxially with the link 15.
The link 16 is connected so as to be pulled up by the swinging of the link 16 energized at 2. A cable 10 is fixed to the end of the link 16, and when excessive tension is applied to the cable 10, the link 16 scrapes against the force of the spring 22, pulling up the actuator 14''. The shut-off valve 14 is switched to stop driving the drilling machine.
