Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid carrying bucket, and more particularly to a bucket for carrying a fluid such as concrete to another place.

[0002]

[Problems to be Solved by the Invention] When constructing a house today, a conventional construction method is generally used in which a foundation stone is placed on the compacted ground and a pillar or the like is erected on the foundation stone. Instead, the foundation is usually constructed along the outline of the house and the positions of the pillars and walls. Although the structure and shape of the foundation differ slightly depending on the building manufacturer, the method of placing concrete in constructing the foundation is generally the same. That is, as shown in FIG. 7, a predetermined portion of the ground 1 is dug up,
After laying a quarry 2 at that location, a foundation 3 serving as a base is constructed on it with concrete. After that, the concrete formwork 4 is arranged on the foundation 3, and the concrete is poured into the formwork 4 to construct the foundation 5 as the rising portion.

The work for placing the foundations 3 and 5 is carried out by suspending a bucket 6 as shown in FIG. 8 on a crane of a mobile crane, pouring concrete 7 from a mixer truck or the like into the bucket 6, and then using the crane. The bucket 6 is suspended above the concrete formwork 4 by the operation of. Then, the operator determines the position of the bucket 6 and opens the lid, while pouring the concrete 7 into the concrete form 4, the bucket 6 is moved along the direction of the concrete form 4, and the concrete 7 is quickly concreted. It is poured into the formwork 4.

However, if the lid of the bucket 6 is opened too wide, the concrete 7 flows out vigorously at once, so the concrete 7 may overflow from the concrete form 4. If the position of the bucket 6 is too high,
The falling position of the concrete 7 may be misaligned and the concrete 7 may be poured onto the formwork 4 itself or out of the formwork 4, and even if the falling position is accurately aimed, the falling concrete 7 May spread greatly, and may protrude to both sides of the formwork 4.

Further, depending on the road conditions at the construction site and the positions of overhead lines such as transmission and distribution lines, it may not be possible to place a crane truck or a mixer truck on the road adjacent to the construction site. The bucket 6 is transported back and forth over the roof of the next house. However,
Since the opening of the lid of the bucket 6 cannot be completely sealed and there is a slight gap, water containing cement may drip from the gap and stain the roof of the next house.

Therefore, the inventor of the present invention can cast the concrete 7 in the bucket 6 into the concrete form 4 accurately and easily, and the cement-containing water does not drip while the bucket 6 is moving. As a result of intensive studies to achieve the above, the present invention has been achieved.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of a fluid carrying bucket according to the present invention will be described in detail with reference to the drawings, taking a concrete carrying bucket as an example.

As shown in FIGS. 1 and 2, the concrete carrying bucket 10 includes a container portion 18 having a tubular portion 14 into which concrete 12 is charged and a reduced diameter portion 16, and a container portion 1.
8, an outlet 20 through which the concrete 12 flows out, an opening / closing means 22 for controlling the amount of the concrete 12 flowing out from the outlet 20, and a flexible tubular body for guiding the concrete 12 discharged from the outlet 20. And 24. Further, on the upper portion of the container portion 18, there is provided a locking tool 28 to which the hook 26 is locked in order to suspend the concrete transfer bucket 10 by a crane such as a crane truck.
A support frame 30 for making the concrete transfer bucket 10 stand on the ground is provided in the lower part of 8.

In this concrete carrying bucket 10, the tubular portion 14 constituting the container portion 18 is formed into a tubular shape so that a large amount of concrete 12 can be transported at a time, and its sectional shape is shown in FIG. As described above, it may be a polygon such as an octagon, particularly a quadrangle or a circle, and is not limited.

A locking tool 28 for locking the hook 26 of the crane is provided on the upper portion of the tubular portion 14, and the locking tool 28 holds the concrete carrying bucket 10 filled with concrete 12. It is configured to withstand extreme load changes such as hoisting, carrying, and hoisting. On the other hand, the support frame 3 is provided below the tubular portion 14.
0 is provided, and this support frame 30 is
When the concrete 12 is put into the container 8, it is made to stand on the ground and fixed, and the concrete transfer bucket 10
Concrete with the crane suspended by a crane
Used for holding by the operator in order to position and at the same time stabilize the concrete transport bucket 10 when pouring out 2 through the tube 24.

Further, the diameter-reduced portion 16 following the tubular portion 14 is formed at an appropriate inclination angle so that the concrete 12 contained therein can be smoothly and entirely discharged from the outflow port 20. There is. If the angle of inclination is small, the speed at which the concrete 12 contained therein flows out becomes slow, which hinders quick work. On the contrary, if the inclination angle is steep, the height of the diameter-reduced portion 16 is too high, that is, too long, and the size of the concrete transport bucket 10 is increased as a whole, but the volume of the diameter-reduced portion 16 hardly increases. In addition, since the external shape becomes large, it becomes difficult to handle and operate the concrete transport bucket 10. Therefore, the inclination angle is 30 to 60 from the horizontal.
More preferably, it is around 45 degrees.

An outlet 20 for discharging the concrete 12 put in the container 18 is provided below the reduced diameter portion 16. The size of the outlet 20 is concrete 12
Is set so as not to hinder workability in consideration of the flow rate of water flowing out by its own weight, the space between the concrete formwork into which the concrete 12 is poured, the size of the foundation, and the like.

At the lower part of the outflow port 20, there is provided a flexible cylindrical body 24 for guiding the concrete 12 flown out from the outflow port 20. The tubular body 24 is formed of resin or rubber, or resin and woven fabric so that water or the like does not leak from the side surface, and in particular, it is not easily worn or broken by the concrete 12 that passes through the inside. Is formed in.

Next, the opening / closing means 22 is configured to press the side surfaces of the flexible cylindrical body 24 from both sides to control the passage cross-sectional area. Specifically, the tubular body 2
A pair of rod-shaped members 32 that press the side surfaces of the rod 4 from both sides, a lever 36 that rotates the rod-shaped members 32 around a support shaft 34, and a pair of the rod-shaped members 32 press each other through the lever 36. The pulling coil spring 38 is configured to urge the pulling coil spring 38 in a rotating direction, and the operating lever 40 that opens and closes the pair of rod-shaped members 32 against the biasing force of the pulling coil spring 38. In addition, reference numeral 42 is the operation lever 40
Is an erroneous operation preventing lever for preventing erroneous operation of the operation lever 4. The erroneous operation preventing lever 42 is rotated around a shaft 44, and the engaging member 46 protruding from the lever 42 is used to operate the operating lever 4.
By engaging 0, the operating lever 40 is locked.

Therefore, the pair of rod-shaped members 32 is constantly urged by the urging force of the tension coil spring 38 through the lever 36 in the direction in which they come into contact with each other. Pressed, tubular body 2
4 The passage inside is blocked. Therefore, the operating lever 4
As indicated by the two-dot chain line in FIG. 1, the pair of rod-shaped members 32 are separated from each other by gradually pulling up the rod-shaped members 32 against the urging force of the tension coil spring 38, so that the cylindrical body 24
The internal passage is opened, and the cross-sectional area of the passage is controlled by operating this operating lever 40.

After the concrete transfer bucket 10 having the above structure is brought to a construction site or the like, a hook 28 of a crane vehicle is locked with a locking tool 28 and is hung down, for example, near a concrete discharge port of a mixer truck. It is erected on the part by a support frame 30. Then, after the concrete 12 is put into the container 18 from the mixer truck, it is hoisted by the crane of the crane truck, the tubular body 24 is placed on the concrete formwork, and then the erroneous operation prevention lever 42 is moved, The engagement member 46 is released from the operation lever 40. Next, the rod-shaped member 3 for pressing the tubular body 24 by operating the operation lever 40 which is the opening / closing means 22.
The two are separated and the concrete 12 is poured into the concrete form through the inside of the tubular body 24. At this time, the operation lever 40 is operated to control the passage cross-sectional area of the tubular body 24 so that the concrete 12 does not overflow from the concrete form, and the crane is operated to move the concrete transfer bucket 10 to the concrete form. By moving along the frame, the concrete 12 is quickly poured into the mold.

When the concrete 12 in the concrete transfer bucket 10 is exhausted, the operating lever 40 is operated to press the tubular body 24 by the rod-shaped member 32 to block the passage, and the erroneous operation preventing lever 42 is moved. , The engaging member 46 is engaged with the operation lever 40. Further, the support frame 30 is formed by bending the distal end side of the tubular body 24.
The concrete 12 and water that flow out through the inside of the tubular body 24 and are suppressed to a minimum. After that, the concrete transfer bucket 10 is transferred in the same manner as described above, and the concrete 12 is charged by a mixer truck or the like,
The above work is repeated.

In the above work, the concrete 1 was put in the state where the tip of the tubular body 24 was put in the concrete form.
If 2 is poured, the concrete 12 can be surely filled, and the operation of the crane for moving the concrete transfer bucket 10 along the concrete form becomes easy. Further, when the concrete transport bucket 10 is transported, the tubular body 24 is bent, so that the concrete 12 is hardly dropped, and a house, a road or the like during transportation is not polluted.

Although the present invention has been described in detail above by taking the concrete carrying bucket as an example, the present invention is not limited to the above-described embodiments.

For example, as shown in FIG. 4, it is possible to provide an elastic member 48 such as rubber or resin having elasticity around the rod-shaped member 32 that presses the side surface of the tubular body 24 from both sides. By providing the elastic member 48, the tubular body 2
The pressure that presses 4 is made uniform, and the internal passage of the tubular body 24 can be reliably blocked.

Further, as shown in FIG. 5, a hook 50 or the like is attached to the tip of the tubular body 24, and when the concrete transport bucket 10 is hung and transported by a crane or the like, the tubular body 24 is bent. The hook 50 may be locked to the shaft 34 or the like. By doing so, the outlet of the tubular body 24 faces upward, and the concrete 12 and water containing its components do not drop. Further, the length of the tubular body 24 may be slightly shorter, and the tubular body 24 does not come off from the support frame 30 and hang down during the transportation of the concrete transport bucket 10.

Next, as shown in FIG. 6, in the opening / closing means 54 of the concrete carrying bucket 52, a shield plate 58 for cutting off the outlet 56 provided in the lower portion of the container portion 18 is centered around the shaft 60. It is also possible to configure so that the shield plate 58 opens and closes the outflow port 56 by rotating an operation lever 62 that is rotatably arranged and is fixed to the shield plate 58. Also in the concrete transport bucket 52 having this configuration, the tubular body 24 is provided continuously to the outside of the outflow port 56, and the same operation and effect as those of the above-described embodiment can be obtained.
