[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete block unmanned transport curing facility capable of taking concrete blocks into and out of a curing room using an unmanned transport vehicle. The present invention also relates to an unmanned transport vehicle used for the unmanned transport curing facility.

[0002]

2. Description of the Related Art A conventional concrete block transfer curing facility for transporting a concrete-implanted formwork from a molding place to a curing room and transporting the cured concrete block from the curing room to the unloading place. Was configured, for example, as shown in FIGS.

That is, the transport curing facility a is provided at the bottom of a main line passage c formed by digging a floor b of a building as shown in FIGS.
As shown in the figure, a rail g for running the parent trolley e carrying the child trolley d is laid, and in the depth direction of the curing room h juxtaposed to one side space of the main lane in a state of being branched to the main lane c. In order to extend the floor, the floor b is dug down to provide the first branch line passage j1, and as shown in FIG. 14, a rail g for running the sub-dolly d is laid at the bottom thereof.

The other space on the other side of the main line passage c is a detachable assembling work space i for disassembling and assembling the formwork. The space is branched into the main line passage c so as to extend in the depth direction of the work space i. The floor b is dug down to provide a second branch line passage j2, and a rail g for running the sub-dolly d is laid at the bottom in the same manner as shown in FIG.

[0005] An end portion of the main line passage c, for example, on one side space, is a filling work space m for filling a form k with concrete and waiting for the filled form to be conveyed. In the branched state, the floor section b is dug down to provide a third branch line passage j3 so as to extend in the depth direction of the filling work space m, and at the bottom thereof, in the same manner as shown in FIG. rail g for running d
Was laying.

The depth of the main line passage c is 1 m.
It is as deep as about 50 cm, and the first, second and third branch passages j1,
The digging depth of j2 and j3 was as deep as about 75 cm.
Thus, the main line passage c and the branch line passages j1, j2,
The reason why j3 was formed by digging down the floor b was because it was necessary to reduce the height of the building as much as possible.

However, a form k filled with concrete
Is transported to the curing room h, in the filling work space m, the pallet n on which the formwork k is placed is placed on the child carriage d. At this time, the support portion o of the child carriage d is lifted to the required height by the hydraulic cylinder p (the same state as shown in FIG. 14). Thereafter, the sub-dolly d is run in the third branch line path j3 (arrow f1 in FIG. 15), and the main line path c is set.
To put the parent carriage e on standby. Thereafter, the parent carriage e is moved toward a required curing room (arrow f2 in FIG. 15),
Here, the child carriage d is lowered, and the child carriage d is caused to travel in the first branch line path j1 (arrow f3 in FIG. 15). As described above, since the supporting portion o of the child carriage d is lifted to the required height,
As shown in FIG. 14, the child carriage d travels with the lower surface q of the pallet n slightly rising from the upper end r of the first branch line passage j1. After being conveyed to the required installation location, the support portion o descends, and as shown in FIG. 16, both end portions s, s of the pallet n are placed on both end portions t, t of the first branch line passage j1. As a result, the transfer of the concrete-filled formwork to the curing room h was completed.

In order to transport the cured concrete block to the demolding / assembling work space i, the sub-dolly d on which the concrete block (form) is placed is caused to travel along the first branch line passage j1 ( Arrow f4 in FIG. 15)
Then, the parent carriage e is moved toward the detachable assembly work space i (arrow f in FIG. 15).
5). After that, the child carriage d is lowered, and the child carriage d is caused to travel along the second branch line passage j2 (arrow f6 in FIG. 15), and the concrete block (form) is transported to the work place. Here, the mold is dismantled using an overhead crane, and the mold is removed.
Thereafter, the assembled formwork k is loaded on the slave trolley d, and the slave trolley d travels along the second branch line passage j2 (arrow f7 in FIG. 15) and gets on the master trolley e, and the master trolley e is Move to the filling work space m (arrow f8 in FIG. 15). Here, the child trolley d leaves the main trolley e, travels along the third branch line j3 (arrow f9 in FIG. 15), and lowers the formwork at a predetermined location.

[0009]

However, when using the above-mentioned transfer curing facility, there are the following problems. Since the main path and the branch path used for transporting the bogie were formed by digging the floor as described above, the floor surface of the building was a dedicated space for running the bogie. Therefore, it has not been possible to respond to such demands even if the floor surface is used as a storage space for various working machines, vehicles, and the like, for example, by freely moving a truck in and out for cleaning up after work is completed.

[0010] Since the floor is dug down and there are steps, there is a problem that there is a danger at the time of assembling / disassembling the formwork, placing concrete, or walking at the time of working.

Further, there is a problem that it is difficult to clean the inside of the building (removal of dropped concrete, etc.) due to the unevenness of the floor.

When a change in equipment in the building occurs in the future, such as the addition of a curing room, a large-scale work of digging the floor to extend the main passage and the branch passage becomes necessary.
There was a problem that the degree of freedom for future design changes was low.

When the parent and child trolley is used, it is usually necessary to install a concrete block in the curing room because the amount of elevation of the supporting part of the child trolley cannot be so large.
It was limited to stacking, and it was not possible to effectively use the curing room space.

[0014] In constructing the transfer curing facility, there is also a problem that a lot of construction time is required and a construction period is prolonged because the floor has to be dug to form a main line passage and a branch line passage.

An object of the present invention is to provide an unmanned transport curing facility for concrete blocks capable of solving such a problem, and to provide an unmanned transport vehicle used therefor.

[0016]

[0036]

The present invention has the following excellent effects. The present invention employs a configuration in which a guide line for guiding an automatic guided vehicle is provided, instead of digging a floor portion to form a passage as in the related art, so that the entire floor surface can be formed flat. As a result, the truck can be freely run on this flat floor surface after finishing work or the like, without having to use the floor surface as a dedicated transportation space, so that clearing and the like can be easily performed. Further, the floor surface can be effectively used as a storage space for vehicles such as forklifts and trucks, and various other working machines.

In addition, since there is no unevenness on the floor surface, there is no danger in operation as in the conventional transport curing facility where the floor is dug, and because there is no unevenness, cleaning (removal of dropped concrete, etc.) is easy. is there.

[0038] Even in the case of adding a curing room or changing the arrangement of the curing room in the future, it is completely different from the case of the conventional facility where the floor is dug, and the guiding line is extended or the arrangement state is changed. By doing so, it is possible to cope easily and at low cost. In addition, even when a plurality of unmanned guided vehicles are run to improve the transfer efficiency, there is an advantage that the object can be easily achieved only by providing the first guide wires in parallel. Thus, according to the present invention, the degree of freedom of design change and economic efficiency are remarkable.

In particular, when the automatic guided vehicle is configured as an unmanned forklift, the lowermost position of the fork can be made closer to the floor surface. There is no waste of space (economics with many dead spaces), such as having to dig as deep as about 1m50cm for the purpose. Therefore, according to the present invention, not only the facility can be easily constructed, but also the dead space can be made extremely small as compared with the conventional one (depending on the position of the front wheels of the forklift, the lowest position of the fork can be set to approximately the floor level). It is also possible to make the space closer in the height direction of the building.

Also, by adopting an unmanned forklift as an unmanned transport vehicle, unlike the conventional facilities, it is possible to stack the concrete-cast formwork in the curing room in a plurality of stages within the range of the elevating amount. Becomes
The space in the curing room can be used effectively.

In particular, when the mast that supports the fork so as to be able to move up and down is configured to be tiltable in a vertical plane, when the fork that lifts the concrete-cast formwork bends so that its tip side is lowered. In addition, by setting the inclination of the mast to a predetermined value, the lifted formwork can be transported while being maintained substantially horizontal, and a concrete block with high accuracy can be manufactured.
