DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sediment bucket automatic overturning device which is used to suspend earth and sand buckets on a crane to carry out earth and sand, ready-mixed concrete, garbage and the like, and to discharge them to a predetermined place.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional earth and sand bucket automatic overturning device (type 1) is configured such that a overturning table 40 is installed at a specific place and a bucket body 41 is hung thereon. Was something. A pair of left and right support pins 45 protrude from the bucket body suspended from the center of gravity by a bucket body suspended from the hook 42 of the crane by the suspension rope 43, and the support pins are supported by the receiving portion 44 of the fall table 40. Then, when the crane is lowered and the suspension ropes are loosened, the bucket body 41 is pivoted around the pin as a fulcrum.
Falls under its own weight and discharges the sediment in the bucket.

[0003] Another conventional device (type 2)
Is shown in FIG. As shown in the figure, when the bucket main body 51 is hung by the hanging rope 52, another falling rope 53 is connected to the bottom of the bucket main body, and the bucket 53 is pulled up when the bucket is suspended in the air. Since the bottom of the bucket body is lifted, the bucket is inverted while being hung by the crane.

[0004]

However, in the conventional type 1, since the place where the earth and sand are discharged is provided with a fall table, the place is limited to a specific place and equipment such as a fall table is required. There was a problem that it could not be discharged at the location.

In the case of Type 2, a falling rope is required in addition to the hanging rope 52. Since this rope extends upward from the bottom of the bucket to a hanging bracket or a crane hook, it is attached. There is a problem in that it hinders the transfer of earth and sand into and out of the bucket, hinders work performance, and hasten pulling of the rope 53 with rapid force, which hastens the damage to the rope.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to eliminate the necessity of an overturning table or ground equipment, and to provide an equipment such as an overturning table. It is an object of the present invention to provide an automatic earth and sand bucket overturning device which can be automatically overturned in a place where there is no space or in the air without a special overturning rope other than a suspension rope.

[0007]

In order to achieve the above object, an automatic earth and sand bucket falling device according to the present invention hangs a bucket main body 1 on a hanger 2 with two left and right hanging ropes 3.4. In a device in which the metal fitting 2 is hung on a hook 5 such as a crane, fixed guide wheels 6.7 for hanging ropes 3.4 are integrally provided on both left and right sides of the bucket body, and the fixed guide wheels 6.7 are provided. And the loop portion 3 of the suspension rope
a. 4a is hung and a part is fixed, and the power cylinder 8 and the moving body 9 which expands and contracts by driving the power cylinder, and the suspending rope is forwardly and backwardly moved by the expansion and contraction movement of the moving body 9 on the hanging fitting 2. Guide wheels 10.1
1.12.13.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 2, a bucket body 1 is formed in a box shape with an open top and a cylindrical shape or a hopper shape. Attach fixed guide wheel 6.7 to.

The fixed guide wheel 6.7 is fixed to the bucket body 1 so as to be non-rotatably integral with the bucket body 1. The fixed guide wheel 6.7 is formed by hanging a suspension rope 3.4 in a loop shape (folded in two). Hung and partially stop 3b. 4b.

As shown in FIGS. 2 and 3, two suspension ropes 3.4 are used as a pair, and each rope 3 '.
4 'is fixed to the moving body 9 of the power cylinder 8, and one of the ropes 3 is pulled out to the left and wound around the guide wheel 12 on the fixed guide wheel 6 on the left side of the bucket body 1, and further from the guide wheels 12'. 11 to the moving body 9
Endless by sticking to. The other rope 4
Is fixed to the moving body 9 with the extreme end 4 'and pulled out to the right, wound around the guide wheel 13 on the fixed guide wheel 7 on the right side of the bucket body 1, and thereby the guide wheels 13'. Similarly, the end portion 4 ″ is fixed to the moving body 9 through the end of the moving body 9 so as to be endless.

The suspension fitting 2 is formed in a beam shape, and a power cylinder 8, a driving device 15, a moving body 9, and a guide wheel 10.11.12.1 of the suspension rope 3.4 are formed in the beam.
2 '. 13. Deploy 13 '.

The power cylinder 8 is operated by a drive unit 15 including a motor and a hydraulic pump, but may be a power source other than a hydraulic type.

As the suspension rope 3.4, a wire rope or a wire cable is used. Further, a chain may be used instead of the rope.

[0014]

The bucket body 1 is set so as to maintain an upward horizontal posture with the moving body 9 shortened by the power cylinder 8. In this state, the bucket body 1 is lifted by the crane.

In a state in which the bucket body 1 is housed in earth and sand or the like and lifted, hydraulic pressure is applied to the power cylinder 8 to move the moving body 9.
Is extended. Then, as shown in FIGS. 2 and 3, the moving body 9 moves to the left (arrow B) in FIG. Hoop 3a. 4a is simultaneously clockwise (arrow B.
C). Therefore, the bucket main body 1 is inverted together with the fixed guide wheel 6.7 in the same direction, the upper opening is turned downward, and the sediment inside is discharged.

To return the bucket body 1 in the downward posture to the original upward horizontal posture, the extended moving body 9 may be shortened by the operation of the power cylinder 8.

As described above, according to the present invention, the fixed guide wheels 6.7 of the suspension ropes 3.4 are integrally provided on the left and right sides of the bucket body, and the fixed guide wheels 6.7 are attached to the fixed guide wheels 6.7. Hoop 3a. 4a is hung and a part is fixed, and the power cylinder 8 and the moving body 9 which expands and contracts by driving the power cylinder, and the suspending rope is forwardly and backwardly moved by the expansion and contraction movement of the moving body 9 on the hanging fitting 2. The guide wheels 10.11.11.13 are provided so that the bucket body is freely suspended from the upward horizontal position while the bucket body is suspended from the crane. It is possible to perform the operation of returning to the bucket easily and reliably, and it is not necessary to provide a fall table or attach a fall rope separate from the suspending rope as in the past. The reversing and returning operations can be performed, and the operation of discharging soil and the like can be performed safely and efficiently with less noise, and the configuration is simple and advantageous in cost.
