Hereinafter, the effect | action of this invention is demonstrated in detail.

Figure 5 is a perspective view showing a state immediately after the hook is entered into the trunnion of the chute equipped with the chute trunnion hook release device according to the present invention, Figure 6 is a churning device of the churn trunnion according to the present invention. Is a perspective view showing a state in which the hook is pulled after entering the trunnion of the chute equipped.

As shown in FIG. 5, first, the sovereignty hook 3 is lowered (up to the descending neckline) and then moved transversely to constitute the apparatus of the present invention installed in the chute 1 on the ground 2. The sovereign hook 3 enters the hook guide guide 20.

After the guide hook (3) having the claw (3-1) attached to the claw entry oil tool (20-1) is guided, and then hoisted, the brace (3-1) is attached to the claw up and down oil tool (20-2). It is positioned so that the latch 3-1 and the hook 3 are lifted so that the chute 1 is lifted up, and the shock absorber is adapted to absorb the shock since the apparatus of the present invention flows back and forth during the pulling of the main hook 3.

When the chute 1 is continuously lifted up, the tension spring is separated by the weight of the weight piece 38 at the lower end of the shandong copper spindle 32 installed inside the housing 30 of the second main flange 10-2 while being separated from the ground. While the 35 is compressed, the rack gear 31 of the shandong copper spindle 32 is lowered,

Rotation of the rotary gear 40 geared with the rack gear 31 of the shankdong spindle 32 and the lock gear 42 of the locking spindle 39 geared to the other side of the lock the lock The spindle 39 rises vertically.

As the locking spindle 39 is raised due to the vertical upward movement, the locking spindle 39 is coupled to and fixed to the spindle locking bracket 11 as shown in FIG. 6.

Therefore, the device of the present invention is integral with the main flanges 10-1 and 10-2 when the chute 1 is impacted, so that the impact is not directly applied, so that problems in equipment operation do not occur.

At this time, the sovereign hook 3 towing the chute 1 is not detached forward due to the locking spindle 39 locking the latch 3-1 even when the chute hook 3 is detached and detached from the trunnion 2 of the chute 1,

In addition, even if the upper and lower guide hole (20-2) of the latch (3-1) does not occur severely severe separation and impact due to the space narrowly deformed even if the hook latch (3-1) in contact with the locking spindle (739) At this time, the flow phenomenon of the main flange (10-1, 10-2) is to be able to absorb the shock.

In addition, due to overloading of only the hook 3 during the removal operation, when the hook 1 is detached, the chute 1 is inclined toward one side that loses its center and the hook 3 hangs due to the suspicion of hook hanging on the trunnion 2. The main flanges (10-1, 10-2) is a double structure to perform the function of preventing deformation and damage of the double structure to provide a reinforcement function to surround both sides of the hook (3), the second main flange The hook 3 is not detached to the side (side) by (10-2).

Further, even when the chute 1 is tilted, the main flanges 10-1 and 10-2 are flowable so that the same angle as the sovereign hook 3 position is always maintained so that the chute 1 can be pulled to the sovereign hook 3. From the moment it is separated from the ground, the hook 3 has a structure that is never separated from the chute trunnion 2.

Accordingly, when the chute 1 is seated on the ground, the tension force of the weight piece 38 is lost, and the shank-dong spindle 32 is lifted by a relative synergistic action to the original position of the tension spring 35. 31) the locking spindle 39 is lowered due to the reverse rotation of the rotary gear 40, and the locking state is released. Thus, the sovereign hook 3 can be easily removed from the trunnion 2 of the chute 1. It is designed to be separated.

As described above, according to the present invention, it is possible to prevent the detachment of the hook from the chute during operation, and also to prevent the breakage and deformation of the hook, and to prevent the large-scale equipment accident and the work process problem that the chute falls to the ground. In addition, the driver's mental anxiety is solved, and the waste of manpower and time is prevented, which greatly improves work efficiency and productivity.
