DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete distribution apparatus for distributing ready-mixed concrete pumped from a concrete pump to a casting site by a transport pipe.

[0002]

2. Description of the Related Art The present inventors have made the apparatus lightweight and simple so that it can be easily transported and assembled by human power. We have developed a concrete distribution device that can move freely and lightly to improve work efficiency.

[0003] The concrete distribution device according to the above development is:
As shown in FIG. 3, a plurality of transport pipes 1 whose both ends are bent upward or downward at right angles are rotatably connected to each other by a swivel joint 2, and these transport pipes 1 are connected to each other.
As shown in FIG. 4, it is configured to be bent in a zigzag shape as a whole so as to expand and contract the entire length, and as shown in FIG. A delivery hose 3 is attached to the distal end of the transport pipe 1 at the distal end.

A is a two-wheel caster, as shown in FIGS. 6 and 7, two wheels 4, a wheel frame 5 for supporting these wheels 4, and an upright from the center of the wheel frame 5. And a rotating column 8 rotatably mounted on the column 6 via a thrust bearing 7, and fixed to the upper end of the rotating column 8 to fix the transport pipe 1. And a pipe band 9.

[0005] The wheel 4 has a wide ultra low pressure tire,
The impact is minimized by lowering the contact pressure on the rebar. The left and right wheels 4 are independently driven to rotate by a motor 10 with a speed reducer and a clutch 11, respectively. The motor 10 and the clutch 11 are operated by a power supply and a control cable.

Since the support 6 and the rotary support 8 are configured to be freely rotatable with respect to each other by the thrust bearing 7, the transport pipe 1 can be directed in a free direction with respect to the two-wheel caster A, or The two-wheel caster A can be moved in any direction regardless of the direction of the transport pipe 1.

As described above, each of the two-wheel casters A is provided with the motor 10 and the clutch 11 for rotationally driving each wheel 4, and these motors 10 and the clutch 11 are operated independently. Therefore, the movement and the direction of the entire transport pipe 1 are comprehensively controlled, but until now, each cable was individually routed to each two-wheel caster, so that the cables hindered the work. Had become.

[0008] Further, with the concrete placing work,
A rod vibrator is used at the same time, but the cable for the vibrator also complicates with the above-mentioned cable, which has spurred a reduction in work efficiency.

On the other hand, as described above, the wheel 4 has a wide ultra-low pressure tire so that the contact pressure to the reinforcing bar is reduced.
There are problems such as a risk of lateral displacement of the wheel casters A and a fall of the main body, and an increase in running resistance due to deformation such as crushing of tires.

[0010]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has as its object to route a cable along a transport pipe,
By attaching the control device etc. to the concrete supply device main body, the device can move freely without obstacles,
An object of the present invention is to provide a concrete distribution device capable of performing a placing operation efficiently by preventing lateral displacement of the device.

[0011]

SUMMARY OF THE INVENTION A concrete distribution apparatus according to the present invention comprises a plurality of transport pipes rotatably connected by a swivel joint, and a plurality of transport pipes movably supporting each transport pipe.
In a concrete distribution device comprising a wheel caster and a wheel drive motor provided on each of the two wheel casters, a power supply and control cable for the wheel drive motor is wired along the transport pipe. I do.
Further, a control box is attached to an arbitrary two-wheel caster, and the cable is connected to the control box.
Further, a converter for a vibrator is attached to a two-wheel caster of a transport pipe at a tip portion, and a power supply and control cable for a concrete bar vibrator is connected to the converter and wired along with the transport pipe. . Furthermore, the lower part of the two wheels of the two-wheel caster is characterized by being opened outward from each other.

[0012]

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 12 denotes a power supply and control cable, which is wired along the transport pipe 1. The cable 12 is routed so as not to hinder the above-described free movement of the transport pipe 1 and not to be damaged or broken by the movement of the transport pipe 1. Reference numeral 13 denotes a control box, which is attached to one of the two-wheel casters A, and to which the cable 12 is connected.

As shown in FIG. 2, the two-wheel caster A is provided with two wheels 14, 14 whose lower parts are open outward. The opening of the lower portions of the two wheels 14 stabilizes the posture of the main body with respect to roll and reduces the influence on the reinforcing bars and the like. Reference numeral 10 denotes a motor, 11 denotes a clutch, 5 denotes a wheel frame, 6 denotes a column, 7 denotes a thrust bearing, 8 denotes a rotating column, and 9 denotes a pipe band, and has the same configuration and function as the members having the same reference numerals.

The control box 13 is used to turn on / off the operation of the wheel driving motor 10 and the clutch 11.
The F operation and the control of the traveling direction and the speed of the wheels 14 are appropriately performed according to a control purpose in accordance with a predetermined program or an instruction of an operator.

Reference numeral 15 denotes a vibrator converter, which is attached to a two-wheel caster A of the transport pipe 1 at the tip. The vibrator converter 15 is also connected to a power supply and a cable 16 for a baonulator. The tip of the cable 16 is a high-frequency vibrator 17.

The cables 12 and 16 are connected to an external power source at a construction site so as to receive power.

[0017]

1) Since the power supply and control cables connected to the motor for driving the wheels and the converter for the vibrator are routed along the transport pipe, the movement of the apparatus and the work are prevented. Therefore, concrete placing work and the like can be efficiently and safely performed. 2) Since the control box and the converter for the vibrator are mounted on the two-wheel casters, the wiring of the cable is facilitated, and the device can move freely without any obstacle. 3) Since the lower portions of the two wheels are opened mutually, the device is stabilized against roll.
