Description

[Detailed description of the invention] This invention relates to a hopper for concrete pouring.
More specifically, a chute for pouring is arranged in front of an opening formed at the bottom of a hopper for pouring concrete for pouring, and the hopper and chute are integrally moved north, south, east, west, and up and down. This invention relates to a hopper for placing concrete in which only the chute can move up and down and rotate independently of the hopper.

Conventionally, when manufacturing concrete molded products using box culverts, etc., concrete is poured into a hopper at a predetermined location, and the hopper is moved east, west, north, south, and up and down using a traveling means such as an overhead crane. After positioning the opening formed at the bottom of the hopper on the culvert formwork, the lid was opened and concrete was poured.

During the above-mentioned pouring process, in order to pour concrete smoothly, it is necessary to position the opening of the hopper accurately along the box culvert formwork, and to prevent concrete from spilling outside the formwork. It is desirable that the top of the box culvert and the opening of the hopper be as close as possible. However, since the hopper containing the concrete for pouring inside is very heavy, large inertia acts upon it when moving it, making it very difficult to make fine adjustments. For this reason, skill is required to position the hopper during concrete pouring, and positioning requires a lot of time, which hinders improvement in work efficiency.

The present invention has been developed in view of the above-mentioned points, and its gist is that a plurality of supports are installed vertically on the lower surface of a base supported by a traveling means that can move north, south, east, and west. one end of the hydraulic cylinder is fixed to the hydraulic cylinder, and the other end is fixed to the lower part of the slide channel which is slidably fitted onto each of the supports and to which the upper part of the storage hopper is fixed; Furthermore, a circular frame is disposed inside the slide channel and can be freely moved up and down by a vertical movement mechanism;
The chute disposed in front of the opening formed at the bottom of the hopper is engaged via a rotating mechanism, making it possible to move the hopper and chute together in the east, west, north, south, and up and down directions, while only the chute can be moved independently. This is a hopper for concrete placement that can move up and down and rotate, and its purpose is to
A pouring chute is installed in front of the opening of the hopper, and the chute can be moved integrally with the hopper in the east, west, north, south, and vertical directions at all times, and during concrete pouring, only the above chute can be moved up and down independently. To provide a hopper for concrete pouring that is movable and rotatable, thereby making it possible to easily position concrete when pouring it into a formwork, thereby improving the efficiency of pouring work. Our goal is to provide a hopper for concrete pouring that can be used to place concrete.

Further, 33 is a running rail arranged facing east and west, 34 is a north-south running rail arranged on the above-mentioned running rail 33 via a running means 35, and 36 is arranged on the above-mentioned north-south running rail. It is a means of traveling, and 37~
40 indicates a box culvert.

Next, the operation will be explained based on the above configuration.

First, concrete is poured into the storage hopper 4 through the hole 2a formed in the center of the base 2 at a predetermined position as shown by arrow A in FIG. After pouring the concrete into the storage hopper 4 in this way, the main body 1 is moved in the east-west direction, that is, at
-Move it in the X direction and the north-south direction (YY direction in the figure) and position it on the box culvert where concrete is to be poured. Box culverts come in various shapes and sizes, as shown with numbers 37 to 40 in FIG. For this purpose, after pouring concrete into box culverts 37 and 38, a high box culvert 3
There are cases where concrete is poured into a box culvert 40 which is lower in height than the box culvert 39, skipping over the box culvert 39. In such a case, it is necessary to raise the lower end of the main body 1 so that it does not hit the box culvert 39. Also, raise it like this and pass the box culvert 39,
When placed on the box culvert 40, in order to smoothly pour concrete into the frame of the box culvert 40, it is necessary to lower the pouring opening to near the upper end of the frame.

The above-mentioned raising and lowering is performed by operating the hydraulic cylinder 7 disposed within the support 3 and moving the slide channel 9 slidably fitted onto the support 3 up and down. In this embodiment, the stroke of the hydraulic cylinder 7 is 1600.
Since a material with a diameter of m/m is used, it is possible to accommodate box culverts of various sizes within this range. In this way, the lower end opening of the main body 1 is brought close to the upper end of the box culvert during concrete pouring, but as mentioned above, concrete is loaded into the storage hopper 4, and the weight of the device itself is also reduced. Since it is heavy, a large amount of inertia acts when moving the whole thing up and down. Therefore, it takes time and getting used to positioning. In other words, if you are not used to it, the lower end opening of the main body 1 and the upper end of the box culvert may come into contact with each other, causing damage, and conversely, if they are too far apart, the poured concrete will spread and come out of the frame of the box culvert. It may be stored away.

The present invention was developed in order to make it easy to make fine adjustments during concrete pouring. The opening 32 can be finely adjusted. That is, as shown in FIG. 7, after the main body 1 is positioned on the box culvert 40 to be poured by means of traveling north, south, east, and west, the hydraulic cylinder 7 is operated to lower the entire box to a certain height. This lowering does not require fine adjustment and can be performed smoothly. Next, the fine adjustment hydraulic cylinder 16 is operated to independently lower only the pouring chute 5 as shown by the arrow T in the figure. Since the above-mentioned pouring chute 5 is light, it can be lowered smoothly without applying a large inertial force. Therefore, the opening 32 formed at the bottom can be easily positioned at the optimal position of the box culvert 40. After the opening 32 of the pouring chute 5 is moved to a predetermined position in this manner, the hydraulic cylinder 30 disposed at the lower part of the storage hopper 4 is operated to open the opening/closing lid 29. With this, the storage hopper 4
The concrete inside flows out into the pouring chute 5, and is then poured into the frame of the box culvert 40 through an opening 32 formed at the bottom of the chute 5. At this time, diffusion prevention plates 31 made of neoprene rubber are placed on both sides of the opening 32, so that the concrete can be poured smoothly within the frame of the box culvert without spreading outside the opening 32. be done. Further, in the above-mentioned pouring process, it is desirable that the concrete to be poured be placed evenly on each side of the box culvert 40, with just the right amount and not enough. However, in the past, it has been difficult to, for example, place the concrete on the side 40b that is oblique to the side 40a after pouring on the side 40a that is parallel to the north and south. However, since the pouring chute 5 is provided with a rotation mechanism 22 in addition to the vertical movement mechanism 12, it can be freely rotated in the direction of arrow R shown in FIG. 40b can be easily placed. That is, as shown in FIG. 4, the hydraulic motor 26 fixed on the side surface of the pouring chute 5 is operated, and the output shaft 26a of the hydraulic motor 26 is rotated.
The gear 27 fixed on the top is rotated. The gear 27 engages with rack teeth 28 disposed on the entire circumference of the side surface of the circular frame 15.
5 can freely move up and down, but is configured not to rotate with respect to the horizontal plane, so that the pouring chute 5 rotates. By rotating the pouring chute 5 in this manner, it is possible to easily pour the concrete even on the obliquely located side 40b.

In this way, the concrete pouring hopper of the present invention allows for fine adjustment during pouring by disposing the pouring chute 5 in front of the storage hopper, and allowing only the pouring chute 5 to move up and down and rotate independently. It was done freely.

As detailed above, the present invention has a plurality of supports 3 hanging down from the lower surface of the base 2 supported by a traveling means that can move north, south, east, and west, and one side end of the hydraulic cylinder 7 is fixed to the upper part of the supports 3. At the same time, the other end is fixed to the lower part of a slide channel 9 which is slidably fitted onto each of the supports 3 and to which the upper part of the storage hopper 4 is fixed, and further, the inner side of the slide channel 9 is fixed. A circular frame 15 is disposed in the hopper and can be freely moved up and down by a vertical movement mechanism 12, and a pouring chute 5 is disposed in front of an opening 21 formed at the bottom of the hopper. The storage hopper 4 and the pouring chute 5 can be integrally moved north, south, east, west, and up and down by engaging through the rotation mechanism 22, and the pouring chute 5 can independently move up and down and rotate. Since this is a hopper for concrete pouring, a chute 5 for pouring is arranged in front of the opening 21 of the hopper 4 for storage, and the chute 5 is always integrated with the hopper 4 for storage in four directions: north, south, east, west, and It is possible to provide a hopper for concrete pouring which can be moved in the vertical direction, and in which only the pouring chute 5 can be vertically moved and rotated independently during concrete pouring. The pouring opening for pouring concrete into formwork such as a culvert can now be easily positioned, improving pouring work efficiency, and the heavy storage hopper can be easily positioned. This invention has various advantages, such as providing a hopper for concrete pouring that can significantly reduce wear and failure of the device since the device does not have to be moved frequently for fine adjustments.
