The pouring pipe 50 is installed along the spring 41 of the crane means 40. The pour pipe 50 forms a portion 51 corresponding to the rotation point of the boom 41 in a flexible corrugated pipe shape to allow the boom 41 to adjust the angle. The pouring pipe 50 is preferably installed so that the end extends from the end of the boom 41 long.

The pressure feeding means 60 may be composed of a hopper 61 and a concrete pump means (65). The hopper 61 is located under the chutes 13 and 23 of the first and second mixer vehicle means 10 and 20, and the concrete pump means 65 is installed under the hopper 61 to the bogie. It is fixed to 30. The chutes 13 and 23 are installed somewhat longer from the first and second mixer vehicle means 10 and 20 and are properly positioned on the hopper 61.

As shown in FIG. 3, the concrete pump means 65 pumps concrete introduced into the hopper 61 by pumping the piston of the hydraulic cylinder 65a to the outside through the discharge port 65b. The pouring hole 50b is connected to the pouring pipe 50 and strongly pumps the concrete to move along the pouring pipe 50. Two or more hydraulic cylinders 65a are preferably installed to pump concrete continuously.

A concrete control valve for controlling the amount of concrete is preferably installed between the concrete pump means 65 and the hopper 61, and a stop valve for opening and closing the flow of concrete is preferably installed in the pipe forming the discharge port 65b. Do. The hydraulic cylinder 65a may be operated by receiving hydraulic pressure from the hydraulic pump of the hydraulic supply means.

Although not shown, the hydraulic supply means having a hydraulic pump is installed in the trolley 30, and supplies hydraulic pressure for operating the boom 41 and the concrete pump means 65 of the crane means 40.

That is, the hydraulic pressure supply means is connected to the hydraulic cylinder 41b of the boom 41 and the cylinder member 45a of the rotation means 45, and the hydraulic cylinder 65a of the concrete pump means 65 to operate the hydraulic pump. The hydraulic pressure generated can be supplied. The operation of the hydraulic pump is preferably controlled from the driver's seat 47 of the crane means 40, the hydraulic cylinder 41b of the boom 41, the cylinder member 45a of the rotating means 45 and the concrete pump means 65 A plurality of hydraulic cylinders (65a) of the corresponding to each is provided in plurality can be supplied to each of the hydraulic pressure as necessary.

The power means 70 is installed on the trolley 30 and supplies power for operating the hydraulic pump of the hydraulic supply means. The power means 7 may be any one of a motor driven by receiving electricity and an engine driven by burning fossil fuel. The power means 70 operates the hydraulic pump by transmitting the rotational power generated by the driving to the hydraulic pump.

Concrete placing device of the present invention having such a structure is to pour concrete through the following process.

The concrete pouring method of the present invention starts by operating the boom 41 of the crane means 40 to position the pouring pipe 50 in the mixer drum 12 of the first mixer vehicle means 10. Alternatively, the concrete pouring method of the present invention may be started from the step of placing the pouring pipe 50 in the mixer drum 22 of the second mixer vehicle means 20, for convenience of description the pouring pipe 50 to the first mixer It begins with positioning in the mixer drum 12 of the vehicle means 10. Regardless of which mixer drum 12, 22 the pouring tube 50 is located, it is clear that the concrete placing method of the present invention is not changed.

As shown in Figure 4, by operating the hydraulic pump of the hydraulic supply means to operate the hydraulic cylinder 41b of the boom 41 and the cylinder member 45a of the rotating means 45 to the first pour pipe 50 It is located in the mixer drum 12 of the mixer vehicle means 10. The spring 41 is rotated and the angle is adjusted so that the pouring pipe 50 is located at the concrete inlet (not shown) of the mixer drum 12.

Thereafter, concrete from the outside is introduced into the hopper 61 of the pressure feeding means 60. The concrete delivered through the mixer vehicle, that is, ready-mixed vehicle is injected into the hopper 61. Subsequently, the hydraulic cylinder 65a of the concrete pump means 65 is operated to pump concrete of the hopper 61 and to inject the mixer drum 12 of the first mixer vehicle means 10 through the pour pipe 50.

Thereafter, when concrete injection is completed in the mixer drum 12 of the first mixer vehicle means 10, the operation of the concrete pump means 65 is stopped. Operation stop of the concrete pump means 65 can be made by stopping the operation of the hydraulic pump. Subsequently, the boom 41 of the crane means 40 is operated to place the pouring pipe 50 in the mixer drum 22 of the second mixer vehicle means 20. By controlling the operation of the cylinder member 45a of the rotating means 45, the pouring pipe 50 is moved to the mixer drum 22 of the second mixer vehicle means 20, and the hydraulic cylinder 41b of the boom 41 is moved. Control the operation of the placing pipe 50 is placed in the concrete inlet (not shown) of the mixer drum 22.

Then, by operating the hydraulic cylinder (65a) of the stationary concrete pump means 65, pumped the concrete of the hopper 61 delivered and introduced by the external ready-mixed concrete vehicle to the second mixer vehicle means through the pouring pipe (50) Injected into the mixer drum (22) of (20).

Thereafter, when concrete injection is completed in the mixer drum 22 of the second mixer vehicle means 20, the operation of the concrete pump means 65 is stopped. Subsequently, the first railroad wheels 11 and 21 of any one of the first and second mixer vehicle means 10 and 20 are driven to perform construction on a concrete construction such as a long tunnel of a railway, a long bridge, and a subway. Move to place (5). The forward movement of the first mixer vehicle means 10 can be moved to the city factory 5, and the reverse movement of the second mixer vehicle means 20 can be moved to the factory factory 5.

Then, as shown in Figure 5, by operating the boom 41 of the crane means 40 to place the pouring pipe 50 in the city factory (5). By controlling the operation of the cylinder member 45a of the rotating means 45, the pouring pipe 50 is moved to the city factory 5, and by controlling the operation of the hydraulic cylinder 41b of the boom 41, the pouring pipe 50 ) Is placed in the place where concrete is to be placed in the city plant (5).

Then, one or both of the first and second mixer vehicle means 10 and 20 are operated to inject the concrete of the mixer drums 12 and 22 into the hopper 61 through the chutes 13 and 23. do. Rotational discharge of the mixer drums 12 and 22 is operated in the driver's seat 14 and 24 to inject concrete into the hopper 61 through the chutes 13 and 23.

Thereafter, the hydraulic cylinder 65a of the concrete pump means 65 is operated to pump the concrete of the hopper 61, and the concrete of the mixer drums 10 and 20 through the pouring pipe 50 to the municipal factory 5. Placing, driving the first rail wheels 11, 21 of the first and second mixer vehicle means 10, 20 alternately back and forth to travel forward and forward the concrete of the mixer drum (12) (22) Pour in (5). Whenever the casting position of the city plant 5 is changed, the position of the placing pipe 50 is changed from time to time so that concrete can be placed at the correct position by adjusting the spreading angle and the rotation angle of the boom 41.

Then, when all of the concrete injected into the mixer drum (12) (22) is exhausted, the above process is repeated and the concrete is poured in place in the city factory (5).

As described above, according to the present invention, since two concrete mixer vehicles can be loaded by placing a large amount of concrete at one time, the mixer vehicle reciprocating through city plants such as a pole tunnel, a pole bridge, and a subway in order to receive concrete The amount of movement of the air is reduced, and the air can be shortened significantly.

In addition, since the concrete can be poured in place by changing the placing position, the construction efficiency and construction efficiency can be greatly improved. For example, if you place concrete in place by changing the placement location, you can minimize the work of shoveling and moving workers, and the vacuum compaction time of concrete is greatly shortened. It can be done very economically.
