Description

  The present invention relates to a material supply machine that supplies concrete, asphalt mixture, and other various pavement materials, and a method of using the material supply machine.

In the construction site where the road is paved, there is a case where the material is not efficiently supplied to the paving lane (area where the paving work is performed: work area) and the working efficiency cannot be improved.
For example, at the site of continuous reinforced concrete pavement construction, a large number of reinforcing bars that serve as reinforcing materials for concrete structures are arranged in a crossing state on a pavement lane. Therefore, when supplying concrete as a pavement material, various devices for supplying the material (concrete) cannot be arranged in the pavement lane where the reinforcing bars are arranged. Therefore, equipment for supplying materials must be arranged on the side of the paving lane (working area).

In such continuous reinforced concrete pavement work, a pavement in which a number of reinforcing bars intersect with each other from the side of the pavement lane (working area) using a material supply machine (concrete supply machine) called a “horizontal machine”. Material is supplied in the lane (work area).
FIG. 10 shows a material supply machine (horizontal machine) 10 used in a conventional pavement operation.
In FIG. 10, a pavement material (concrete in the case of continuous reinforced concrete pavement) is supplied to the wetting machine or material supply machine 10 via the material supply port 5.
The supplied pavement material is a pavement lane (working area) 50 through a material discharge conveyor 6 (only the vicinity of the right end is shown in FIG. 10) and a material cross feed conveyor 7 inside the material supply machine 10. Supplied in.

Here, as shown in FIG. 10, the material supply port 5 is provided only in front of the material supply machine 10 (to the left in FIG. 10). Therefore, for example, in order to put the pavement material from the material supply vehicle 20 such as a concrete mixer truck into the material supply port 5, the material supply vehicle 20 is placed in front of the material supply machine (horizontal machine) 10 (in FIG. 10). It is necessary to stop on the left.
In other words, in the conventional material supply machine 10, even if the material supply vehicle (for example, a concrete mixer truck) 20 is stopped on the side (side away from the pavement lane 50: in FIG. 10, below the material supply machine 10). The pavement material could not be supplied from the material supply vehicle 20 (on the side) to the material supply port 5.
In FIG. 10, reference numeral 40 denotes a traffic band.

The production capacity of concrete or asphalt mixture at the concrete factory and other various paving materials and the leveling capacity of the concrete leveling machine are at a high level, which is sufficient for the requirements of the paving work site. Can be met.
However, the amount of work when using a material supply machine (horizontal machine) at the pavement work site depends on the ability to supply material from the side of the pavement lane 50 by the material supply machine (horizontal machine) 10. End up.
And as above-mentioned, in the conventional material supply machine 10, pavement material is supplied only from the one vehicle for material supply (for example, concrete mixer truck) 20 stopped in the front.
Therefore, the ability to supply the material from the side of the pavement lane 50 is also relatively low, corresponding to the ability to supply the pavement material from one material supply vehicle 20 to the material supply machine 10.

As a result, the operation of supplying material from the side of the pavement lane 50 or supplying the pavement material from the material supply vehicle 20 to the material supply machine 10 becomes a so-called “bottleneck” in the entire pavement operation. It was.
In addition, due to the presence of such “bottleneck”, the high level of capability (manufacturing capability and leveling capability of pavement material) in concrete factories and concrete leveling machines cannot be fully exhibited.

As another conventional technique, a pavement material supply device has been proposed that can supply a pavement material to a finisher with a feeder when two-layer road pavement is performed (see Patent Document 1).
However, the related art (Patent Document 1) aims to supply two kinds of pavement materials to the pavement lane by two feeders, and the above-mentioned problems in supplying materials to the material supply machine Cannot be resolved.

The horizontal conveyor 8 includes a conveyor moving cylinder 82 at the end opposite to the material receiving hopper 81.
The conveyor moving cylinder 82 is provided for sliding the horizontal conveyor 8 along the moving rail 83. Here, the direction in which the moving rail 83 extends coincides with the extending direction of the horizontal conveyor.

In the state where the conveyor moving cylinder 82 is extended, the horizontal conveyor 8 is slid along the moving rail 83 to the lower right side of FIG. 3 (extends: state shown in FIG. 3).
On the other hand, in the state where the conveyor moving cylinder 82 is contracted, the horizontal conveyor 8 is slid along the moving rail 83 to the upper left side of FIG. 3 (contracts: see FIG. 4).

Next, with reference to FIGS. 5-8, in the operation | work which pours raw concrete into the pavement lane 50 (or work area) which has arrange | positioned the reinforcing bar in the mesh form using the material supply machine 100 of FIGS. 1-4, The aspect which supplies raw concrete from several concrete mixer trucks to the material supply machine 100 of FIGS. 1-4 is demonstrated.
As shown in FIG. 5, in the continuous reinforced concrete pavement work, when performing the work of pouring concrete (so-called “green concrete”) into the pavement lane 50 (or work area) in which the reinforcing bars are arranged in a mesh shape, The material feeder 100 is disposed in the traffic band 40 on the left side in the traveling direction (lower side in FIG. 5).
Then, in order to arrange the concrete mixer truck (material supply vehicle) 21 in front of the material supply machine 100 (left side in FIG. 5), for example, as shown in FIG. In many cases, the concrete mixer truck 21 can pass through only a narrow area on the lower side.

In FIG. 5, the first concrete mixer truck 21 passes through a narrow region on the left side of the material supply machine 100 (lower side in FIG. 5) and turns forward in front of the material supply machine 100 (see D in FIG. 5). Trajectory), the vehicle stops in front of the material feeder 100 (left side in FIGS. 5 and 6) (see FIG. 6).
At this time, as shown in FIGS. 5 and 6, the horizontal conveyor (expandable conveyor) 8 is in a contracted state, so the second concrete mixer truck 22 interferes with the horizontal conveyor (expandable conveyor) 8. Without this, it is possible to pass through a narrow area on the left side of the material feeder 100 (lower side in FIG. 6).

In FIG. 6, the first concrete mixer truck 21 stopped in front of the material feeder 100 (left side in FIG. 6) supplies the material in front of the material feeder 100 (left side in FIG. 6) as in the prior art. Supply raw kon to mouth 5.
As described with reference to FIGS. 1 to 3, the ready-mixed food supplied to the material supply port 5 is supplied to the pavement lane 50 via the material discharge conveyor 6 (see FIG. 2) and the material lateral feed conveyor 7. .

At the same time that raw concrete is supplied from the first concrete mixer truck 21 stopped in front of the material feeder 100 (left side in FIG. 6), or before raw concrete is supplied from the first concrete mixer truck 21. At this stage, as shown in FIG. 6, the second concrete mixer truck 22 passes through a narrow area on the left side of the material supply machine 100 (lower side in FIG. 6), and the first concrete mixer truck 21. To the left (lower side in FIG. 7) (see FIG. 7).
More specifically, in the second concrete mixer truck 22, the raw concrete outlet 22o is in a position just beside the horizontal conveyor 8 in a contracted state (in FIG. 7, a position immediately below the horizontal conveyor 8). To stop.

  In the state shown in FIG. 6, since the horizontal conveyor (expandable conveyor) 8 is in a contracted state, the second concrete mixer truck 22 does not interfere with the horizontal conveyor (expandable conveyor) 8, and does not interfere with the material supply machine. The vehicle can pass through a narrow area 100 left (lower side in FIG. 6) and reach the left side (lower side in FIG. 7) of the first concrete mixer truck 21.

When the second concrete mixer truck 22 moves to the left (lower side in FIG. 7) of the first concrete mixer truck 21, the horizontal conveyor 8 is extended (FIG. 7).
As described above, in the second concrete mixer truck 22, the raw concrete outlet 22o is located at a position directly beside the horizontal conveyor in a contracted state (in FIG. 7, a position immediately below the horizontal conveyor 8). It is stopped at. Therefore, if the horizontal conveyor 8 is extended, the raw concrete outlet 22o of the second concrete mixer truck 22 and the position of the material receiving hopper 81 of the horizontal conveyor 8 are aligned.
Then, the raw concrete is supplied from the raw concrete outlet 22o of the second concrete mixer truck 22, and the raw concrete (supplied from the second concrete mixer truck 22) is supplied to the material supply machine 100 by the horizontal conveyor 8. The material is conveyed to a position just above the material supply port 5.
This state is shown in FIG.

In the state shown in FIG. 7, two concrete mixer trucks 21 and 22 are simultaneously supplying materials.
As is conventional, the concrete mixer truck 21 feeds raw concrete into the material supply port 5 from the front of the material supply machine 100 (left side in FIG. 7).
On the other hand, the concrete mixer truck 22 puts the raw concrete into the horizontal conveyor 8 from the left side of the material supply machine 100 (opposite side of the paving lane 50: the lower side in FIG. 7). The ready-mixed concrete introduced to the horizontal conveyor 8 is transported on the horizontal conveyor 8 to the material supply port 5 side, and dropped or thrown into the material supply port 5 from the opening 8o (located immediately above the material supply port 5). .

According to the illustrated embodiment, as shown in FIG. 7, it is possible to supply raw concrete to the material feeder 100 from the two concrete mixer trucks 21 and 22 at the same time. For this reason, the operation of supplying the ready-mixed concrete from the concrete mixer trucks 21 and 22 to the material supply machine 100 is performed with higher efficiency than before.
As a result, it is possible to prevent the operation of supplying raw concrete from the concrete mixer trucks 21 and 22 to the material supply machine 100 from becoming a so-called “bottleneck” in the entire paving operation.

In FIG. 7, while the raw concrete is being supplied from the two concrete mixer trucks 21 and 22 to the material feeder 100 at the same time, the third truck is located behind the second concrete mixer truck 22 (right side in FIG. 7). The concrete mixer truck 23 is waiting.
When the raw concrete supply from the two concrete mixer trucks 21 and 22 to the material feeder 100 is completed, as shown in FIG. 8, the two concrete mixer trucks 21 and 22 are separated to the front of the material feeder 100 ( Arrows Y1 and Y2 in FIG.

As shown in FIG. 5, the third concrete mixer truck 23 passes through a narrow area on the left side (lower side in FIG. 5) of the material supply machine 100, and in front of the material supply machine 100 (left side in FIG. 5). Stop at.
Hereinafter, as described with reference to FIGS. 5 to 8, raw concrete is supplied to the material feeder 100 from the two concrete mixer trucks.

FIG. 9 shows a modification of the material feeder 100 shown in FIGS.
In the material supply machine 100 shown in FIGS. 1 to 4, when the concrete mixer truck runs on the side of the material supply machine 100 (downward in FIG. 1) by contracting the horizontal conveyor 8 by the conveyor moving cylinder 82. The interference with the horizontal conveyor 8 is prevented.
On the other hand, in the modification shown in FIG. 9, in the material supply machine denoted by reference numeral 101 as a whole, the horizontal mixer 8A is moved upward in the vertical direction to prevent interference between the concrete mixer truck and the horizontal conveyor 8A. ing.

In FIG. 9, the horizontal conveyor 8 </ b> A moves to a position indicated by a solid line (downward position) and a position indicated by a virtual line (two-point difference line) (upward position) due to expansion and contraction of the vertical movement cylinder 85.
When a concrete mixer truck (see FIGS. 5 to 8; not shown in FIG. 9) travels on the side of the material supply machine 101 (downward in FIG. 1), the vertical movement cylinder 85 is contracted and a horizontal conveyor is used. 8A is moved to an upper position indicated by a virtual line. If the horizontal conveyor 8A is at the upper position indicated by the phantom line, even if the concrete mixer truck runs on the side of the material feeder 101 (lower side in FIG. 1), the horizontal conveyor 8A and the concrete mixer truck interfere with each other. There is no end.

On the other hand, when supplying the raw control from the side of the material supply machine 101 (lower side in FIG. 1), the vertical movement cylinder 85 is extended to move the horizontal conveyor 8A to the lower position indicated by the solid line in FIG.
If the horizontal conveyor 8A is at the lower position indicated by the solid line, the material is supplied from the raw mixer outlet 22o (see FIG. 7: not shown in FIG. 9) of the concrete mixer truck on the side of the material feeder 101 (lower side in FIG. 1). The prepared raw concrete is conveyed by the horizontal conveyor 8 and supplied (introduced) to the material supply port 5 (see FIG. 1: not shown in FIG. 9) of the material supply machine 101.

For other configurations and operational effects, the modification of FIG. 9 is the same as the embodiment of FIGS.
However, moving the horizontal conveyor 8A upward (bounces up) means that the movement of the horizontal conveyor 8A becomes large. Therefore, the system with higher safety is a system in which the horizontal conveyor 8 is contracted (slid) by the conveyor moving cylinder 82 as in the embodiment of FIGS.
Although not shown, in the embodiment shown in FIGS. 1 to 8, it is possible to provide a mechanism for moving the horizontal conveyor in the vertical direction as shown in FIG.

The illustrated embodiment is merely an example, and is not intended to limit the technical scope of the present invention.
For example, although the illustrated embodiment describes the case of continuous reinforced concrete pavement, the present invention is also applicable to the supply of asphalt mixture and other various pavement materials.
