The hook 42 is preferably formed in a semi-circular shape for ease of operation.

The rotating shaft 44 is divided into two and configured to rotatably support the operating rod 40, respectively, and a part of the rotating shaft 44 is flanged so as not to be easily separated from the operating rod 40. 46 is formed.

Each opposite end of the rotating shaft 44 is fixed to a part of the outer circumferential surface of the operating plate 56, and the operating plate 56 is inserted into the buffer housing 50 and slidably installed therein.

The shock absorbing housing 50 is a cylindrical member, one end of which is closed and the other end of which is open to allow the operation plate 56 to be inserted.

The buffer housing 50 is provided with a pair at a predetermined distance from each other on the fixed frame (60).

The fixed frame 60 is firmly bolted to the bottom surface of the traveling body 10, and the center portion of the width of the fixed frame 60, that is, the distance between the pair of shock absorbing housings 50, is positioned at about half the position. An elastically movable limit switch 62 is provided.

The limit switch 62 is electrically connected to drive the drive motor 36 in reverse rotation, and is disposed to be in contact with the rear end of the operation rod 40.

A part of the outer circumferential surface of the buffer housing 50 is formed with a guide groove 52 cut in a predetermined length in the longitudinal direction, and the guide grooves 52 are disposed to face each other when mutually arranged.

An elastic spring 54 is inserted into the shock absorbing housing 50, and then an operating plate 56 capable of suppressing the elastic spring 54 is inserted therein, and the operating plate 56 has a 'ㅓ' shape. It is inserted so that the elastic spring 54 can be suppressed while being well supported so as not to be separated.

The operation relationship of the apparatus of the present invention having such a configuration will be described with reference to FIGS. 3 and 4.

As shown in Figures 3 and 4, when the gust wind blows the wind speed is 20m or more per second, the drive motor 36 is rotated forward while rotating the wire drum 38 to release the wire (w).

At the same time, the actuating rod 40 causes the hook 42 portion to sag downward due to its own weight, and the hook 42 which is located between the stopper 26 and the adjacent stopper with the rolling phenomenon of the unloading machine It is caught by one stopper 26.

Subsequently, as the hook 42 is caught by the stopper 26, a strong load acts on the working rod 40, and the working rod 40 tries to move to the hook 42 side.

At this time, since the rear end of the actuating rod 40 is elastically constrained on the actuating plate 56 by the rotating shaft 44, the actuating plate 56 strongly compresses the elastic spring 54 while the unloading machine continues to be pushed. The rear end of the actuating rod 40 is moved together with the actuating plate 56 in a direction opposite to the moving direction of the unloading machine (in fact, the unloading machine is moved) to elastically restrain the movement of the unloading machine.

In this way, the emergency braking operation, that is, the braking system, is activated so that it is doubled with the basic braking operation of the unloading machine.

Here, the drive motor 36 is controlled by means such as a timer to be driven only for a predetermined time during the forward rotation drive signal to loosen the wire (w).

When the gust stops, the unloader (unloader) is slightly moved to the opposite side, and at the same time, the locking state of the hook 42 becomes idle, and the return force of the elastic spring 54 is applied to the operating plate 56 at the original position. Will come back.

When the operating plate 56 is retracted and comes into contact with the limit switch 62, the driving motor 36 is reversely rotated from the starting plate 56, thereby winding the operating rod 40 by winding the wire w on the wire drum 38. It will return to the previous initial state.

In this way, the unloader can be effectively emergency braked.

As described in detail above, the present invention prevents the unloader's jungle phenomena by emergency braking by combining with the basic braking means when the unloader outdoor equipment is pushed by the gusts strong winds through which the unloader equipment damage or the ship and It provides the effect of eliminating the risk of safety accident by excluding the risk of collision.
