[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a sediment bucket into which earth and sand are put, lifted by a crane, moved and discharged.

[0002]

2. Description of the Related Art For example, when excavating a shaft, excavated earth and sand is put into a vessel-type earth and sand bucket in the shaft, and the earth and sand bucket is lifted and moved by a crane. The moved sediment bucket is rolled over at the stockyard, and the sediment inside is discharged. This rollover was performed by a worker hooking a wire on a sediment bucket. That is, when the wire is hung on one end of the earth and sand bucket, for example, and the crane is moved to move the earth and sand bucket further, the earth and sand bucket is pulled in the direction where the wire is hung and can be rolled over.

[0003]

However, according to the conventional vessel-type earth and sand bucket, the earth and sand bucket is suspended via one pin so that the earth and sand bucket can be easily rotated in order to overturn the earth and sand bucket. For this reason, the earth and sand bucket is unstable, and the earth and sand may be spilled while moving.

[0004] Further, an operator who hangs a wire to overturn the earth and sand bucket is required, and there is a possibility that the worker may come into contact with the earth and sand bucket or the like.

[0005] Furthermore, the loading capacity of earth and sand was small due to the vessel bottom shape of the vessel. SUMMARY OF THE INVENTION An object of the present invention is to provide an open / close sediment bucket capable of preventing spilling of earth and sand, unmanned workers, and increasing a loading capacity.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and comprises a substantially box-shaped bucket body 3 lifted and moved by a crane, and a substantially fixed bucket body 3 fixed to a side surface of the bucket body 3. The bucket body 3 engages with the downwardly facing hook 9 and the hook 9 of the bucket body 3 that descends.
A bar 11 provided on the ground in order to roll over, a door 13 provided on a side surface of the bucket body 3 opposite to the hook 9 and opened and closed about an upper side, and a lock 15 for keeping the door 13 closed. And a link mechanism 29 for releasing the lock 15 by contacting the bar 11 locked to the hook 9 and a spring 27 for returning the lock 15 to the open / close type sediment bucket.

[0007]

The openable sediment bucket 1 filled with earth and sand is lifted and moved by a crane. Then, when the crane is lowered by a crane to take out earth and sand, the bar 11 provided on the ground is locked to the hook 9. At this time, the bar contacts the link mechanism and the door is unlocked. When the bucket body 3 further descends, the bucket body 3 tilts and rolls over. As a result, the earth 13 that is being opened is discharged. Thereafter, when the openable sediment bucket 1 is raised and leveled again by the crane, the door 13 closes around the upper side as an axis. When the bar further rises, the hook 9 is separated from the bar 11 and the link mechanism 29 does not work, and the lock 15 is returned by the spring 27.
Thus, earth and sand can be put into the bucket body 3 again.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a view showing an operation of rolling over the openable and closable earth and sand bucket according to the present embodiment to discharge earth and sand, and FIG. 2 is a view showing a state before or after the bucket body rolls over. 3 is an enlarged view of the bucket body of FIG. 2, FIG. 4 is a partially cutaway side view of FIG. 3, and FIG. 5 is a plan view of FIG.

For example, when digging a tunnel or the like, a shaft is dug in a plurality of places. Excavation equipment such as a shovel car is arranged in the shaft. The excavator puts the excavated earth and sand into the openable earth and sand bucket of the present embodiment.
The earth and sand bucket is lifted and lowered by a crane. The crane is provided on a trolley, for example, and can move in a horizontal direction. The soil bucket moved in this way carries the earth and sand to the stock yard.

The bucket body 3 of the openable / closable earth and sand bucket 1 has a substantially box shape, and is instructed to be able to ascend and descend and move horizontally in a stable state by suspending four places by a dedicated hanging tool 5. The exclusive hanging tool 5 is further suspended by a crane hook 7. Two hooks 9 (see FIG. 5) are fixed to the side surface of the bucket body 3. The tip of the hook 9 is open downward.

A bar 11 for engaging the hook 9
Is provided at the upper end of the rollover device 31 provided on the ground. The height of the rollover device 31 is sufficiently larger than the lateral dimension of the bucket body 3, so that the bucket body 3 can take a sufficiently rolled state.
A door 13 is provided on a side surface of the bucket body 3 opposite to the hook 9 and can be opened and closed about an upper side as an axis. A lock 1 of the bucket body 3 is
An engagement portion 17 is provided for the engagement of the first and second engagement members 5. The lock 15 is rotatable about a pivot point 19 with respect to the bucket body 3, and is pulled by a pulling link 21 to release the engagement. The pulling link 21 is further pulled through a turning link 23, and the turning link 23 is turned by a contact bar 25. The contact bar 25 is provided substantially parallel to the hook 9 (see FIG. 5), and is located at a position where the contact bar 25 can contact the bar 11 locked to the hook 9. Further, the lock 15 is urged in a direction in which the lock 15 is engaged with the engagement portion 17 by a spring 27 provided between the tension link 21 and the bucket body 3.

The operation of the embodiment will be described below. With the door 13 closed and locked, earth and sand is put in from above the bucket body 3 in the shaft by, for example, a shovel car or the like. Then, the bucket body 3 is lifted and lifted by the crane, and moves in the horizontal direction by, for example, a trolley. When moving to the stockyard, the bucket body 3 is lowered by the crane. The lowering is performed so that the hook 9 fixed to the side surface of the bucket body 3 is locked to the bar 11 of the rollover device 31 provided on the ground portion of the stockyard. When locking is performed, bar 1
1 comes into contact with the contact bar 25, and the pivot link 23 pivots,
Since the pulling link 21 is pulled, the lock 15 turns around the turning fulcrum 19 and comes off the engaging portion 17. When the link mechanism 29 operates in this way and the lock is released,
The door 13 is in an open state, and is rotatable around the upper side. When the descent is further continued, the bucket main body 3 is tilted and eventually rolls over. As a result, the sediment inside automatically exits and is transported to the stockyard. Thereafter, when the bucket body 3 is lifted and lifted again by the crane, the door 1 is placed in a state where the bucket body is horizontal.
When the hook 3 is closed and then the hook 9 is separated from the bar 11, the link mechanism 29 does not work, and the lock 15 is locked by the spring 27.
Rotates, and engages with the engaging portion 17 of the door 13. When the lock is restored in this manner, the bucket body 3 can be filled with earth and sand again. In this state, the bucket body moves horizontally and returns to the shaft again.

As described above, according to the present embodiment, the rollover is automatically performed, and the lock 15 of the door 13 is released and opened, regardless of the number of workers who lay a wire to roll the earth and sand bucket. The earth and sand are carried out, and thereafter, the door 13 is automatically closed and the lock 15 is returned. Therefore, it is possible to prevent an accident such as a worker coming into contact with a sediment bucket or the like, to save labor costs, and to eliminate the time required to wire the wire, thereby making it possible to shorten the cycle of discharging the soil. Further, since the bucket body 3 is rolled over with a strong force by hooking the hook 9 to the bar 11, the exclusive hanging tool 5 can hang the bucket body at four places and can take a stable state, so The spilling of earth and sand from the bucket body 3 can be prevented. Furthermore, there is no need to take the shape of a ship bottom that is easy to roll over with wires,
Since it can be made almost box-shaped, the loading capacity of earth and sand can be increased.

In the above embodiment, the contact bar 25 constituting a part of the link mechanism is provided in parallel with the hook 9, but in other embodiments, the hook 9 is connected to the contact bar 25. Can also serve as a function. That is, the lock itself can be released by rotating the hook itself by a fixed amount and operating the link mechanism.

[0015]

As described above, according to the openable sediment bucket of the present invention, the bucket body can be rolled over by locking the bar provided on the ground to the hook of the bucket body. As described above, there is no need to make the bucket body unstable by supporting it with one pin so that the bucket body can be easily rotated, and it is possible to prevent spilling of earth and sand. Further, an operator for hanging a wire to overturn the earth and sand bucket is not required, so that it is possible to prevent an accident in which the worker comes into contact with the earth and sand bucket and to save labor costs.

[0016] Further, the time required for hanging the wire can be omitted, and the cycle for carrying out the earth and sand by the earth and sand bucket can be reduced, so that the operation time can be shortened. Further, since a substantially box-shaped bucket body can be adopted instead of a vessel type having a ship bottom shape, the loading capacity of earth and sand can be increased.
