Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agitator truck equipped with a crane for transporting and placing fresh concrete.

[0002]

2. Description of the Related Art Conventionally, the work of placing ready-mixed concrete on a construction site has been delayed in mechanization, but in the case of placing it manually,
It is painful, labor intensive, and inefficient.
That is, the manpower-carrying and placing work is a dirty work that is covered with cement milk, and the quality and workability of the concrete itself is likely to change with the passage of time.

However, when the driving place is high, it is inevitable to use a large driving machine such as a pump truck. Although it is acceptable for a large amount of concrete pouring, the height of the pouring place is, for example, only about 2 to 5 m, and in the case of a small amount of pouring, use an expensive large pouring machine. Will result in an extra cost increase. Further, the use of a large-sized placing machine may not be possible in a narrow work site because it is necessary to secure a large storage area.

By the way, a small agitator truck is a vehicle used to transport a relatively small amount of ready-mixed concrete. This small agitator truck is equipped with a mixing tank on the truck chassis and discharges fresh concrete from a chute provided at the rear of the mixing tank.However, when pouring directly from the chute, the height of the pouring place is high. The limit is about 1.5m. Therefore, when placing at a higher height, is it due to manual work?
Alternatively, it is necessary to use, for example, another belt conveyor and a crane vehicle that supports it. However, using a crane truck in addition to the agitator truck is still costly and space consuming.

[0005]

As described above, the operation of placing fresh concrete by manpower requires a lot of labor and is inefficient. In addition, large-scale driving machines such as pump trucks that have been conventionally used for driving in high places, although they are good for a large amount of driving, cause an extra cost increase for a small amount of driving, and a narrow work site. Can not be used in. Furthermore, in the conventional small agitator truck, even if it was attempted to drive directly from the agitator, the height was limited to about 1.5 m.

The present invention is intended to solve such problems, and particularly to provide an agitator truck which is suitable for a small amount of driving, can be efficiently driven in a small and high place, and can reduce the construction cost. With the goal.

[0007]

In order to achieve the above object, an agitator truck with a crane according to the present invention has a truck type traveling body, an agitator mounted on the truck type traveling body, and the truck type traveling body. It is equipped with a mounted crane.

[0008]

In the agitator truck with crane of the present invention,
While agitating the fresh concrete with an agitator, the truck-type traveling body travels to carry the fresh concrete. In addition, when pouring concrete, in addition to pouring concrete directly from the agitator, it is also possible to place it using a belt conveyor or hopper supported by a crane,
As a result, it is also possible to place it in a small high place. For example, when a belt conveyor is used, concrete supplied from an agitator is sent to a pouring place by a belt conveyor supported by a crane. When a hopper is used, concrete is put into the hopper from an agitator, and then the crane is used to carry the hopper to a position above the pouring place and drop the concrete from the hopper.

The crane 6 has a boom 7 that swings, rises and falls, and expands and contracts by using a hydraulic device as a drive device. A hook 9 is suspended from the tip of the boom 7 by a wire 8 that can be paid out. In addition, the maximum volume on the carrier 4
A 1.7 m ³ unit agitator 11 is provided. The unit agitator 11 has a drum 12 that rotates to stir the fresh concrete C inside, and a drive device including an engine that drives the drum 12 in front of the drum 12.
13 are provided. At the rear of the drum 12, a batcher 14 is provided on the upper side and a chute 15 for discharging the concrete C is provided on the lower side. Further, on the carrier 4 located below the chute 15, there is provided a conveyor mounting portion 16 which can be swung and raised and lowered.

Reference numeral 21 is a belt conveyor. This belt conveyor 21 is of a two-point carrier roller type.
It has a width of 3.5 m and a length of 5 m. Then, one end 24 of the frame 23 of the belt conveyor 21 is the conveyor mounting portion.
It is designed to be detachably attached to the 16. In addition,
A belt cleaner 25 including rollers and the like is provided below the frame 23. Further, the belt conveyor 21 is
It can be detachably accommodated on a conveyor accommodating portion 26 including a frame provided on the carrier 4 of the truck type traveling body 1. 31 is a hopper, and this hopper 31 is a double-opening and closing type, and the maximum capacity is 0.3 m ³ . The hopper 31 has a hook hooking portion 32 on the upper part. Further, on the carrier 4, in front of the agitator 11, there is provided a hopper storage portion 33 in which the hopper 31 can be detachably stored.

Next, the operation of the above configuration will be described. When the fresh concrete C is transported, the truck-type traveling body 1 travels, and the agitator 11 stirs the fresh concrete C during that time. Further, as shown in FIG. 1, the belt conveyor 21 and the hopper 31 are stored on the carrier 4 of the track type traveling body 1. After the arrival at the construction site, the concrete C is discharged from the agitator 11 and placed. If the casting location is less than 1.5m, agitator 11
Concrete C can be placed directly from the chute 15. Further, even if the pouring place is higher than that, the pouring can be performed by using the belt conveyor 21 or the hopper 31.

As shown in FIG. 2, when the belt conveyor 21 is used, the wire 9 is first attached to the hook 9 of the crane 6.
The belt conveyor 21 is supported via the belt conveyor 21, and the belt conveyor 21 is removed from the conveyor storage section 26 by the operation of the crane 6 and the assistance of the worker.
Attach one end 24 of 23 to the conveyor mounting 16. Also,
The angle (height) and direction of the belt conveyor 21 are adjusted so that the other end of the belt conveyor 21 is located above the driving place. In this way, the crane 6 is used for mounting and dismounting the belt conveyor 21 with respect to the conveyor storage portion 26 and the conveyor mounting portion 16, and for maintaining the angle and changing the direction of the belt conveyor 21 during use. That is, supported by the crane 6, the belt conveyor 21 maintains a predetermined angle and direction. Then, the concrete C is discharged from the agitator 11 and the belt conveyor 21 is driven. Agitator
The concrete C discharged from the chute 15 of 11 is carried on the belt 22 of the belt conveyor 21 and carried upward,
It drops from the other end of 21 to the place where it is placed.

Placing using such a belt conveyor 21 is possible within a range of 180 ° rearward. Then, in the actual test result, 1 m ³ could be placed in 6 minutes. The following test results were obtained regarding the angle and height of the belt conveyor 21 that can be placed and the changes due to the mix of the concrete C. That is, regardless of the aggregate diameter, in the case of a slump 8 cm, an angle of 28 ° and a height of 5 m were possible. Also, when the slump is 12 cm, the angle is 14 ° and the height is 3.5.
It was possible up to m. The installation of the belt conveyor 21 was completed by two workers in about 3 minutes. Further, by using an appropriate belt cleaner 25, the mortar adhesion to the belt 22 was almost eliminated.

Further, as shown in FIG. 3, when the hopper 31 is used, the hook 9 of the crane 6 is first attached to the hopper 31.
The hopper 31 is supported by being hooked on the hook hanging portion 32 of the above, and the hopper 31 is moved from the hopper storing portion 33 to below the chute 15 of the agitator 11 by the operation of the crane 6 and the assistance of the worker. In this state, from this chute 15 green concrete C
Is discharged and put in the hopper 31. Then, the hopper 31 is carried by the crane 6 to a position above the pouring place, the lower end of the hopper 31 is opened, and the concrete C in the hopper 31 is dropped. The supply of the concrete C from the agitator 11 to the hopper 31 and the supply of the concrete C from the hopper 31 to the pouring place are repeated as many times as necessary.

Placing using such a hopper 31 is as follows.
It can be freely operated in the range of 360 °, and the height of the casting place is 5 m.
The above case is also possible. However, when the hopper 31 is used, it is necessary to reciprocate the hopper 31 between the agitator 11 and the setting place.
If you use, you will be more efficient.

As described above, according to the configuration of the above-described embodiment, a single truck equipped with the agitator 11 and the crane 6 and capable of carrying the belt conveyor 21 and the hopper 31 can be moved to a small and high place up to about 5 m. Can be placed without labor, efficiently, and at low construction cost. That is, it is possible to achieve labor saving, labor saving, and cost reduction of the setting work, which in turn improves the image of the work environment. Further, since the truck itself is small, a large vehicle storage area is unnecessary, and work can be performed even in a small work place.
Although this agitator truck with a crane has no problem with the placing speed as described above, it is particularly effective for placing a small amount of the material. In the case of large-scale driving, it is better to use a pump car.

The present invention is not limited to the above embodiment, and various modifications can be made. For example,
The specifications of the truck type traveling body, the crane, the agitator, the belt conveyor or the hopper are not limited to those in the above-mentioned embodiment, and various types can be used. Further, in the above-mentioned embodiment, both the belt conveyor and the hopper can be installed in the track type traveling body, but only one of them may be provided, and further, the belt conveyor and the hopper may be separately prepared.

[0018]
