Equipped with a fitting piece 35, 45 connected to the auxiliary phase, the lower lever 34, 44, respectively, in the center of the front end, the operation bar according to the opening operation of the hopper gate 140 When the lower movement of the (20) by the upper, lower levers (30), (40) mounted oppositely so as to hinge the connecting points of the upper, lower fixing parts (33), (43) in the opposite direction to the pivot axis, During the lowering movement of the operation bar 20, the upper gate 39 is reversed, and the lower gate 49 is moved forward and discharged of the return call loaded therebetween, while the operation of the operation bar 20 In the ascending movement, the upper gate 39 is advanced and the lower gate 49 is reversed to reverse the discharge of the return call. To. Referring to the operation of the hopper fall prevention device of the skip hoist having the structure as described above are as follows.

That is, the bucket 120 is lowered along the bucket rail 110 in order to discharge the return call stored in the hopper 130 to the empty upper part and open the hopper gate 140 that interferes with the hopper gate ( At the same time as the 140 is rotated in the counterclockwise direction about the rotation shaft 141, the operating bar 20 is rotated as shown in FIG. 4 while the horizontal connecting shaft 11 of the main lever 10 fixed to both sides is rotated. It descends in the direction of arrow A and performs discharge work of return call.

In this case, the upper bar 30 and the upper lever 30 of the V-shape connected to each of the upper fixing hole (33) of the operation bar 20, the operation bar 20 in the operation structure according to the connection structure When the lower side of the upper auxiliary lever 34, the upper gate 39, the tip of which is fitted to the fitting piece 35 of the back along the upper rail 38 in the direction of the arrow A1 to the upper gate 39 inside the hopper 130 Since it is possible to intervene, the upper gate 39 can temporarily block the return call from falling directly below.

On the other hand, the V-shaped lower portion which is hinged to the lower through-hole 22 and the lower fixture 43 of the operation bar 20, respectively, and connected simultaneously to the assembly state of the upper lever 30 is operated simultaneously The lever 40 advances the lower gate 49, whose tip is fitted to the fitting piece 45 of the lower auxiliary lever 44, along the lower rail 48 in the direction of arrow A2, and moves the lower gate 49 to the hopper 130. Since only the return call stored between the upper and lower gates 39 and 49 can be withdrawn outside, the bucket located below the hopper gate 140 without falling down as in the prior art. You can put it in (120).

On the other hand, when the hopper gate 140 is rotated in the clockwise direction by the bucket 120 is moved upward along the bucket rail 110, the closing operation to stop the discharge operation of the return call, the horizontal connecting shaft ( The operating bar 20 connected to 11) is lifted up in the direction of arrow B shown in FIG.

In this case, when the V-shaped upper lever 30 connected to the upper auxiliary lever 34 is advanced by the operation of the operation bar 20, the upper gate 39 connected to the fitting piece 35 is opened. Since the upper gate 39 located in the hopper 130 can be taken out of the hopper 130 by advancing along the upper rail 38 in the direction of arrow B1, the return call in the hopper 130 is directly below. It can be dropped. On the other hand, the lower lever 40 retracts the lower gate 49 connected to the fitting piece 45 of the lower auxiliary lever 44 along the lower rail 48 in the direction of arrow B2 to move the lower gate 49. Since the hopper 130 may intervene, only a certain amount of return calls are stored between the upper and lower gates 39 and 49 so that the lower gate 49 of the lower gate 49 is lowered according to the lowering of the operation bar 20. When opened, the bucket 120 can be discharged without falling.

Therefore, according to the present invention, the operation bar 20 is connected to the main lever 10 of the hopper gate 140, which is opened and closed by the bucket 120 moving along the bucket rail 110, and is operated up and down. And the upper and lower levers 30 and 40 which are connected to the upper and lower gates 39 and 49 to move forward and backward in opposite directions, respectively, thereby returning calls stored in the hopper 130. Through the hopper gate 140 can always be discharged to a certain amount of bucket 120, because when the opening, closing operation of the hopper gate 140 can completely prevent a large amount of return calls scattered to the outside as a gap as in the prior art. Therefore, it is possible to prevent unnecessary manpower input and environmental pollution from falling light treatment.
