The present invention solves the problems of the prior arts registered by the same applicant. The screw operation of the auger crane and the bike-riding hammering operation are mainly performed continuously, and are formed to be coupled with the male and female coupling units for fast and simple fastening.

A male body coupling connected to a auger crane boom is lowered so that a male fastener coupled to a screw or a bicycle hitch is inserted into an insertion hole of an arm fastener and then the rocker fastener is rotated a little to engage the engaging projections to engage with each other. In order to solve this problem, a vertical safety pin hole is formed in an arm fastening hole and a male fastening hole, and a driving pin hole is formed in a driver's seat The safety pin is moved up and down by radio control so as to form a rigid coupling.

When the safety pin is detached, the safety pin is positioned in the vertical safety pin hole of the arm fastening hole. When the safety pin is coupled, the safety pin is lowered so that part of the rod is inserted into the safety pin hole of the male fastening hole and the remaining part is located in the safety pin hole of the arm fastening hole. And the male and female coupling units are not separated by the vibration.

The control box is composed of a control circuit including a receiving part and a servo and a battery for raising / lowering a lever connected to the safety pin.

The control method may be formed such that when the power is turned off, it is in a disconnection state, and when the power is turned on, it is in a coupled state. Alternatively, the control method may be configured to operate in an opposite manner. .

The safety pin is inserted into a safety pin hole formed vertically in the body of a male and female coupling unit which combines a screw and a vibrating hammering of an auger crane so that the safety pin can be inserted and removed by radio control. The male and female coupling units are loosened or loosened, thereby solving the problem of the related art, and the male and female coupling units can be firmly engaged with each other. In addition, the present invention is advantageous in that a driver can selectively operate a screw or a hammer It is convenient to combine the safety pins by wireless connection, and it is also effective to improve work efficiency by quick replacement work.

1 shows the fastening state of a screw and a vibrating hammer according to the present invention.
2 shows the separation of the male and female coupling units and the control box of the present invention.
Figure 3 illustrates one embodiment of the control box of the present invention.
4 shows a state in which the safety pin is raised and lowered by a lever operation.

1 shows a state in which the female and male coupling units of the present invention are coupled to a screw and a hammer, and a male fastener is not shown in a state where male fasteners are inserted into the insertion holes of the female fasteners.

In FIG. 1, the upper part of the arm fastener is coupled to the auger crane boom, and the male screw fasteners of the same type are coupled to the respective screw and hammers, so that the driver can easily combine the screw and the hammer in the driver's seat.

As shown in FIG. 1, the control box 130 is formed on the upper surface of the male fastening body, and FIG. 2 shows a state in which the male fastening member, the female body fastening body and the control box are separated from each other.

It can be seen that a coupling member for coupling to the auger crane boom is formed on the upper surface of the arm body coupling body 120, and a coupling member for coupling to the screw or the hammock is formed in the lower portion of the male coupling bore body 110, The arm is coupled to the screw and the hammer, and the arm fastener is coupled to the boom frame. If necessary, the arm fastener is coupled to the screw or the hammer. When the driver lowers the arm body fastener from the driver's seat and the male fastener is inserted into the female fastener insertion hole And then the cancer body fixture is rotated a little.

The inner surface of the insertion hole of the female body fastening body 120, into which the male fastening tool is inserted, is provided with a protruding portion for engaging with the female fastening hole on the surface of the male fastening body 110, And details thereof are described in detail in the prior art application No. 20-2018-0003895, so that the description thereof is omitted.

In auger crane screwing work at civil engineering and construction site, there is a problem that a large force of rotation is accompanied and a hammering operation involves severe vibration, so that the male and female coupling unit is loosened or loosened due to continuous vibration or rotation.

In order to solve such a problem, in the present invention, a vertical safety pin hole 119 is formed at a predetermined depth in the male fastening body 110, a vertical safety pin hole 129 is formed in the rocker body 110, And the safety pin is lowered and raised by the safety pin hole, so that the male and female coupling units are fastened and separated.

The safety pin holes 119 and 129 formed in the male fastening body and the female body fastening body must be formed so that the holes are aligned with each other when the male fastening hole and the male fastening hole are rotated.

It is seen that the control box for moving the safety pin 131 up and down is coupled to the upper surface of the arm body body 120.

3 shows the inside of the control box of the present invention. A lever 132 is connected between the safety pin 131 and the servo 133 to receive a radio signal from the transmitter and operate the servo in the control unit to raise or lower the safety pin. .

The control box is formed with a control box safety pin hole 139 at a position and size coinciding with the safety pin hole of the arm fastening hole.

Also, a battery 136 is mounted in the control box and used as a power source. The circuit unit 135 includes a receiving unit, a power switch, and the like.

FIG. 4 shows a state in which the safety pin 131 is lifted and lowered. When the male and female coupling units are to be separated, the safety pins are raised. When the male and female coupling units are to be tightened, the safety pins are lowered.

Since the safety pin 131 in the raised state is located in the safety pin hole 129 of the female coupling, the male and female coupling unit is not in a state of being coupled with the safety pin, and the female coupling can be rotated in this state to be separated from the male coupling .

In the lowered state, the safety pin 131 is in a state in which a lower portion of the safety pin is inserted into the safety pin hole 139 of the male fastening body. In this state, a safety pin coupling is formed between the male and female coupling units, And maintains a firm bond in the screw or vibrating hammering operation.

As described above, in the male and female coupling units of the auger crane, the safety pin is essential for joining and separating, and it is difficult and inconvenient for the operator to directly replace the safety pin, The safety pin can be easily and easily separated from the driver's seat by using a transmitter or a remote control.

The embodiments of the present invention are not limited to the above embodiments and include various embodiments that can be practiced in the ordinary skill in the art.

The safety pin includes a safety pin hole and a safety pin hole. The safety pin hole is formed in the safety pin hole. Hole 140: cap 210: screw 220: bike-riding hammer
