The tip of the hose connected to the concrete pump 8 is moved to a desired input port provided on the upper working floor, and in this state, the concrete pump 8 is operated to drop the fresh concrete from the input port. Next, the tip of the hose described above is moved to the next charging port, and the same work is repeated.

[0006]

In the slip-form construction method, it is necessary to maintain the compressive strength of the concrete exposed below the form panel substantially uniformly over the entire circumference.

Therefore, the driving height at one place is 10c.
The number of driving points must be increased while keeping the distance to m to 20 cm or less, and as a result, the worker must frequently move the tip of the hose.

However, in the slip-form construction method, it is indispensable to carry out each work such as rebar arrangement, concrete placing, and form raising as planned under a strict time schedule. Frequent manual movement of the concrete distribution hose while receiving it involves a great deal of effort and always carries the risk of process delays.

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a self-propelled truck for concrete distribution, which can move a hose for concrete distribution quickly with little labor. To aim.

Is attached to the trolley body with a predetermined pipe having a discharge port for discharging the fresh concrete at the other end.

Further, the self-propelled carriage for concrete distribution of the present invention is configured such that the supply port or the discharge port of claim 1 is rotatable.

Further, the self-propelled trolley for concrete distribution of the present invention is one in which an alarm sound generator or a warning rotary light is attached to the trolley body of claim 1 or 2.

[0013]

In the concrete distributing self-propelled carriage of the present invention, the concrete distributing hose connected to the concrete pump is connected to the supply port side of the pipe. And
The traveling mechanism is appropriately operated to cause the carriage to travel, and the discharge port of the pipe is moved to the input port of the upper working floor.

Here, in the case where the operating mechanism is provided with an operating portion which can be remotely operated, the operating mechanism can be operated at a place where it does not interfere with the movement of the concrete distributing truck and the hose.

As can be seen in the figure, the concrete distributing self-propelled carriage 11 is provided with a rotary drive mechanism 15 and a turning mechanism 16 as a traveling mechanism in the carriage main body 12, and the rotary drive mechanism 15 includes the rear wheels 14, By rotating 14 the automatic concrete distribution truck 11 can be moved forward or backward. The rotary drive mechanism 15 is, for example, 2
Attach two electric motors to the bottom of the trolley body 12,
The rotary shaft of the electric motor may be connected to the axles of the rear wheels 14 and 14 via gears, chains and the like, respectively.

The turning mechanism 16 turns the horizontal axis of rotation of the front wheel 13 about the vertical axis by a desired angle,
The traveling direction of the self-propelled carriage 11 for concrete distribution can be turned.

A pipe 17 having a hollow cylindrical cross section is mounted on the trolley body 12, and a supply port 18 for supplying fresh concrete and a discharge port 19 for discharging the fresh concrete are provided at both ends thereof. Is provided.

Here, as can be seen clearly in FIG. 1 (b), the supply port 18 is rotatable about the vertical axis, and is not restricted by the concrete distribution hose 23, and the concrete distribution itself is not restricted. The carriage 11 can be freely handled.

At the tip of the discharge port 19, a box-shaped receiving member 21 composed of only side plates is attached.
The discharged fresh concrete hits the side plate and falls almost directly below, and like the supply port 18, in order to facilitate positioning with respect to the input port not shown, while holding the handle 20, it moves around the vertical axis. It can be rotated.

Further, an alarm sound generator 24 and a warning rotary lamp 25 are attached to the trolley body 12 in order to call attention to surrounding workers during traveling.

Self-propelled truck 1 for concrete distribution according to the present embodiment
In Fig. 1, as shown in Fig. 2 (a), the hose 23 connected to the concrete pump 8 is connected to the supply port 18 of the pipe 17 of the self-propelled truck 11 for distributing concrete. Then, the rotary drive mechanism 15 and the turning mechanism 16 are appropriately operated to move the concrete distribution self-propelled carriage 11 on the upper working floor 6, and the discharge port 19 of the pipe 17 is a hopper 31 which is a charging port of the upper working floor 6.
