DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dam concrete transport vehicle and a method of transporting dam concrete using the transport vehicle, and in particular, concrete prepared in a batcher plant is finally suspended by a concrete bucket and struck. The present invention relates to a dam concrete transport vehicle and a dam concrete transport method using the transport vehicle.

[0002]

2. Description of the Related Art Conventionally, the following method has been proposed and put into practical use as a method for transferring dam concrete from a batcher plant to a concrete receiving place provided near a dam construction site. A plurality of (usually two) concrete buckets are placed on a regular flat body carrier, and reciprocate between the batcher plant and the concrete receiving place. The concrete is poured into the concrete bucket by the batcher plant and reaches the concrete receiving place. The concrete bucket is conveyed, suspended at the concrete receiving place, transferred to a predetermined place, and the concrete in the concrete bucket is poured. The concrete is transported to the concrete receiving place by the mixer truck (mixed concrete truck), and the concrete is poured into the concrete bucket at the concrete receiving place. A track is laid from the batcher plant to the concrete receiving place, and the concrete prepared by the batcher plant is transported to the concrete receiving place by a transfer car running on the track, and the concrete is poured into the concrete bucket at the concrete receiving place. A so-called rear dump type special transport vehicle that lifts the front side of the dam concrete storage tank mounted on the loading platform and unloads the concrete backward, transports the concrete prepared in the batcher plant to the concrete receiving place, Pour the concrete into the concrete bucket at the receiving location.

[0003]

However, in the conventional method of transporting a plurality of concrete buckets mounted on a flat body transport vehicle, the concrete stored therein is compacted due to vibrations during transport and the concrete buckets cannot be opened. In addition, there is a problem that loading and unloading of concrete buckets to and from a transport vehicle requires time and effort. That is, the transport vehicle has to wait until the two concrete buckets that have been transported have finished placing and returned to the transport vehicle, so that the transport efficiency of the transport vehicle decreases. . In addition, this method requires a waiting time for the transport vehicle to arrive at the concrete bucket next time, unless a plurality of transport vehicles are waiting at the concrete receiving location. There is a need to secure the site.

[0004] In the conventional method of transporting dam concrete by a mixer truck, when dam concrete is transported by a mixer truck,
Concrete has a tendency to separate, and there is a problem that the inside of the mixer is severely damaged when dam concrete with large aggregate is transported. In addition, it takes time for pouring (discharging) into concrete buckets and it is efficient. The problem is that it is not.

Further, the above-mentioned conventional method of transporting by a transfer car is capable of carrying a large amount, but the minimum radius of the curved part of the track is large (laying of a sharply curved track is difficult in terms of safety), and it may be used depending on terrain conditions. There is a problem that an impossible case occurs.

Further, in the above-mentioned conventional method of transporting by a rear dump type transport vehicle, in order to accurately pour concrete into a concrete bucket having a relatively small diameter, the concrete storage tank of the transport vehicle must have a special shape. In addition, in order to discharge all of the loaded concrete in the concrete storage tank that is long in the front-rear direction, the front side of the concrete storage tank must be lifted considerably high, and a strong and long hydraulic cylinder is required. There is a problem that the equipment becomes expensive, and after pouring concrete into one concrete bucket, the concrete bucket waits until the concrete bucket finishes casting and returns, or another Replace the empty concrete bucket with a new one (move the truck sideways or move the concrete bucket Replaced so as to match the position of the transport vehicle.) Having the need to make, has a problem of reducing the conveying efficiency crazy and transfer cycle of the transport vehicle and the transport cycle of the concrete bucket.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has been developed in consideration of the above problems. It is an object of the present invention to provide a dam concrete transportation method capable of transporting concrete.

[0008]

In order to solve the above-mentioned problems, according to the present invention, in order to solve the above-mentioned problems, according to the first invention, a concrete inlet 11 is provided at the upper end. A concrete discharge port 12 is provided on one side, and a plurality of vessels 10 whose diameters are sequentially reduced downward from the lower side of the concrete discharge port 12 are placed on the bogie section 2 of the self-propelled vehicle 1a. Outlet 1
2 is directed to the side of the self-propelled vehicle 1a, and placed side by side in the front-rear direction of the self-propelled vehicle 1a.
Of the concrete discharge port 12 is pivotally connected to the bogie unit 2 with the longitudinal axis 3 of the self-propelled vehicle 1a, and the vessel 10 is connected between each vessel 10 and the bogie unit 2. A jack 4 that rotates about the center axis 3 is attached to each of the jacks 4.
Each of the chute pivot shafts 5 is provided with a chute 6 pivotally attached to the chute pivot shaft 5 at a position slightly central from one end thereof. Between the part closer to the other end side than the chute pivot shaft 5 and the fixed part such as the bogie unit 2 is provided with a technical means in which a rotary jack 7 for raising and lowering the chute 6 is attached. It is.

According to a second aspect of the present invention, a roadway 51 is formed between the place where the batcher plant 50 is installed and the concrete receiving place 53 where the dam is to be constructed. An outlet 12 is provided, and a plurality of vessels 10 whose diameters are sequentially reduced downward from the lower side of the concrete discharge port 12 downward are self-propelled through the concrete discharge port 12 on the bogie unit 2 of the self-propelled vehicle 1a. While turning to the side of the expression vehicle 1a,
The self-propelled vehicle 1a is placed side by side in the front-rear direction, and a portion near the lower side of the concrete discharge port 12 of each vessel 10 is pivotally attached to the bogie unit 2 with the front-rear direction axis 3 of the self-propelled vehicle 1, respectively. A jack 4 for rotating the vessel 10 about the shaft 3 is attached between the vessel 10 and the bogie section 2. Further, a chute is provided at a position below the concrete discharge port 12 of the bogie section 2. Each of the chute pivot shafts 5 is provided with a chute 6 pivotally attached to the chute pivot shaft 5 at a position slightly central from one end by the chute pivot shaft 5. A dam concrete transporting vehicle 1 having a rotating jack 7 for moving the chute 6 up and down between a portion approaching the other end and a fixed portion such as the bogie unit 2, prepared by the batcher plant 50. Done concrete Bet the concrete receiving location 53
The concrete is directly transferred from the vessel 10 of the dam concrete carrier through the chute 6 to the concrete bucket 52 on the floor among the concrete buckets 52 used in plural at the concrete receiving place 53. The technical means is characterized in that the concrete bucket 52 into which the concrete is poured and the concrete bucket 52 is successively suspended and transported by a normal suspension transporting means.

[0010]

Next, the operation of the present invention will be described. First, in the dam concrete transport vehicle of the present invention, since each vessel 10 has the concrete discharge port 12 facing the side of the self-propelled vehicle 1a, the vessel 10 is rotated about the shaft 3 as a center axis so that each vessel 10 is rotated. It has the function of discharging the concrete inside 10 to the side of the bogie unit 2.

Since each vessel 10 has a portion in the vicinity of the lower side of the concrete discharge port 12 pivotally connected to the bogie section 2 with the longitudinal axis 3 of the self-propelled vehicle 1a, the concrete discharge when discharging the concrete. The outlet 12 has the effect of not changing its position even if it turns.

Further, since the present invention has the chute 6 and the chute 6 is independent of the rotation of the vessel 10, the position of the chute 6 can be reliably determined. Concrete outlet 12
Since the diameter of the portion below the lower side is sequentially reduced downward, one end thereof can be exposed to below the concrete discharge port 12, and the concrete flowing out of the vessel 10 is placed in the concrete bucket 52 at a predetermined position. It has the effect of reliably pouring in water.

Further, since the bottom area of the vessel 10 is reduced by reducing the diameter of the lower portion, the stored concrete is prevented from being compacted at the bottom during transportation.
Even when concrete is poured out, an effect that enables the entire amount to be smoothly poured out is exhibited.

In the method of the present invention, since the dam concrete transport vehicle is used, loading in the batcher plant is performed by moving the self-propelled vehicle 1a back and forth to the concrete delivery port which usually has only one location. By doing so, it is possible to match the concrete inlets 11 of the plurality of vessels 10 with the above-mentioned concrete supply port, and it is possible to complete the loading in a short time.

At the receiving place 53, concrete is poured out to the side of the self-propelled vehicle 1a via the chute 6, so that concrete can be poured into a plurality of (usually two) concrete buckets 52, 52 at the same time. Alternatively, while one concrete bucket 52 is pouring concrete, concrete can be poured into another concrete bucket 52, and the concrete pouring can be completed in a short time.

Specifically, two concrete buckets 52 are prepared, and the dam concrete transport vehicle 1 is prepared by mounting two vessels 10 having the same capacity as the concrete bucket 52. Then, it is assumed that one of the dam concrete transport vehicles 1 performs a concrete loading operation on the batcher plant 50 side, and another one performs a concrete pouring operation at the concrete receiving place 53. Further, the concrete is cast by alternately suspending two concrete buckets 52, 52 at a concrete receiving place 53. Therefore, one concrete bucket 52 is poured into the remaining concrete bucket 52 at the concrete receiving place 53 from the dam concrete transport vehicle 1 into the remaining concrete bucket 52. When the concrete pouring operation is completed, the batcher plant 50 Since the concrete loading operation of the other dam concrete transport vehicle 1 has been completed on both sides, both dam concrete transport vehicles 1 and 1 start off, and the dam concrete transport vehicle 1 that has left the batcher plant 50 side receives the concrete. When arriving at the place 53, one concrete bucket 52 finishes the casting and leaves the concrete receiving place 53 empty.
The concrete is poured into the concrete bucket 52, and after the concrete bucket 52 being poured is returned at that time, the concrete is poured into the concrete bucket 52, and then the concrete bucket 52 returns to the batcher plant 50 again. By repeating the above operation, the action of matching the transport cycle of the concrete bucket 52 with the transport cycle of the dam concrete transport vehicle 1 is exhibited. In addition, if the number of dam concrete transport vehicles 1 is increased or decreased according to the distance of the roadway 51, the number of concrete buckets 52 to be used is increased or decreased, or the number of vessels 10 per vehicle is increased or decreased, the transport cycle is matched. That can be done.

[0017]

Next, an embodiment of the present invention will be described with reference to the accompanying drawings. In the figure, 1 is a dam concrete transport vehicle of the present invention, and this dam concrete transport vehicle 1
A concrete inlet 11 is provided at the upper end, and a concrete outlet 12 is provided on one side, and a plurality of vessels 10 whose diameters are sequentially reduced downward from the lower side of the concrete outlet 12 are reduced to a bogie of the self-propelled vehicle 1a. The concrete discharge port 12 is placed on the portion 2 so as to face the side of the self-propelled vehicle 1a, and is placed side by side in the front-rear direction of the self-propelled vehicle 1a.

The vessel 10 has a concrete inlet 11 at the upper end and a concrete outlet 12 on one side.
The concrete outlet 12 is formed by sequentially reducing the diameter of the lower portion from the lower side downward from the lower side. The upper surface is used as a concrete inlet 11 and one side is opened as a concrete outlet 12.

While the concrete inlet 11 may be open, the concrete outlet 12 needs to be provided with an opening / closing lid. As the opening / closing lid, as shown most clearly in FIG. 3, a damper type lid 15 or the like can be used.
5 is pivoted to the vicinity of the concrete inlet 11,
A jack 16 for opening and closing is connected to the lid 15. Of course, the lid 15 is not limited to a damper type, but is a slide type in which a vertical rack is provided on the lid and the lid is moved up and down by a pinion that rotates forward and backward by a drive source to open and close the opening. Alternatively, in FIG. 4, a chute 6 described later is also used as a lid. That is, the chute 6 shown in FIG. 4 is press-fitted in a state where the concrete discharge port 12 is closed at the time of elevating. In this case, when pouring concrete described later into the concrete bucket 52, the chute 6 first In this state, the concrete discharge port 12 is fully opened in this state, and a large amount of concrete flows at a time. Therefore, it is needless to say that the lid 15 which can be opened and closed separately as shown in the example of FIG. In addition, it is more reliable to attach the lid 15 to load a soft slump such as mortar.

The self-propelled vehicle 1a can use an ordinary truck (preferably using puncture-less tires for safety reasons) having a so-called flat body truck unit 2. The vessel 10 is used as the truck. In mounting on the unit 2, in this embodiment, the base plate 17 is fixed on the carriage unit 2 and mounted on the base plate 17.

Then, the portion near the lower side of the concrete discharge port 12 of each vessel 10 is pivotally connected to the bogie section 2 with the longitudinal axis 3 of the self-propelled vehicle 1a. Are fitted with jacks 4 for rotating the vessel 10 about the shaft 3 as a central axis.

The shaft 3 for pivotally supporting the vessel 10 is attached to a stay 3a erected on the base plate 17 on the bogie unit 2 in the front-rear direction of the self-propelled vehicle 1a. It pivots close parts. The vessel 10 is placed on the bogie section 2 of the self-propelled vehicle 1a with the concrete outlet 12 facing the side of the self-propelled vehicle 1a and arranged in the front-rear direction of the self-propelled vehicle 1a. Therefore, the vessel 10 is lifted on the side opposite to the concrete outlet 12 so that the vessel 10
The whole is inclined in the lateral direction (in FIG. 2 to FIG. 4, the left side is low and the right side is high), and the stored concrete is discharged in the lateral direction (left direction in the figure) of the self-propelled vehicle 1a. You can do it. In addition, this vessel 10
In the figure, two units (tanks) are used, but it goes without saying that three or more units may be arranged on the carriage unit 2.

The jack 4 has a rod end pivotally attached to a substantially central upper portion of the vessel 10 and a lower end of the cylinder on the carriage 2 (more precisely, on the carriage 2 via the base plate 17). Each is pivotally connected. The jacks 4 are attached to both sides of each vessel 10 (both sides in the front-rear direction of the self-propelled vehicle 1a).

Further, a chute pivot shaft 5 is provided at a position below the concrete discharge port 12 of the bogie unit 2, and each chute pivot shaft 5 is provided with a portion slightly closer to the center from one end than the chute pivot shaft. Shoot 6 pivoted by 5
A rotary jack 7 for raising and lowering the chute 6 is attached between a portion of the chute 6 closer to the other end side than the chute pivot shaft 5 and a fixed portion such as the bogie unit 2.

That is, the above-mentioned chute 6 is pivotally attached to the center portion from one end by the chute pivot shaft 5 so that the chute 6 can be moved downwardly as shown by broken lines in FIG. 2 to FIG. One end portion enters a space created by reducing the diameter of the lower part of the vessel 10 below the concrete outlet 12. A jack 7 is attached between a portion of the chute 6 that is closer to the other end than the chute pivot shaft 5 and a fixed portion such as the bogie unit 2, so that the chute 6 rotates the vessel 10. Independent rotation (up and down movement) can be performed independently of this.

The control device of the jacks 4, 7, 16 can be realized in various ways by the prior art, so that illustration and description thereof will be omitted. However, in this embodiment, the inside of the driver's seat of the self-propelled vehicle 1a and the bogie The same control device is provided on the rear left side of the section 2.

In the dam concrete conveying method of the present invention, a roadway 51 is formed between the place where the batcher plant 50 is installed and the concrete receiving place 53 where the dam is to be constructed.

The batcher plant 50 is, of course, a conventionally known one, and mixes and stirs the aggregate in the aggregate storage 54, the cement in the cement silo 57, water, and other additives as necessary. And adjust the dam concrete.

Then, the concrete receiving place 5
3 is preferably formed by securing a flat ground having an area on which a concrete concrete truck can be mounted and a plurality of concrete buckets can be placed on the side thereof. However, in the illustrated embodiment, at the construction site of the water use dam D, a sufficient area of the ground cannot be ensured within the working radius R of the crawler crane 55, so that only the area on which the plurality of concrete buckets 52 can be landed is described later. A temporary pier was constructed along 51 and secured. The concrete receiving place 53 by the temporary pier is along the road 51, in other words, along the side of the concrete truck 1 traveling on the road 51, the concrete bucket 52
Are arranged in a row.

The concrete receiving place 53
Can be appropriately changed depending on the method of suspending and transporting the concrete bucket 52. For example, when the concrete bucket 52 is suspended and transported by a cable crane (not shown), the landing location of the concrete bucket 52 may be the concrete receiving location 53. Of course it is.

If the dam concrete carrier 1 can travel between the batcher plant 50 and the concrete receiving place 53, the road 51 may be an existing one or a road for another purpose. Alternatively, if it becomes necessary to change the concrete receiving place 53 on the way, the roadway 51 may be changed. In addition, since this type of road 51 is usually temporarily provided in terms of ordinary expenses, and the road width cannot be sufficiently secured, it is desirable to provide a road width extending portion 51a for passing a vehicle in an appropriate place.

Then, a concrete inlet 11 is provided at the upper end.
A concrete discharge port 12 is provided on one side, and a plurality of vessels 10 whose diameters are sequentially reduced downward from the lower side of the concrete discharge port 12 are placed on the bogie section 2 of the self-propelled vehicle 1a. Self-propelled vehicle 1 at exit 12
a, and placed side by side in the front-rear direction of the self-propelled vehicle 1a.
The jacks 4 that pivot the vessel 10 about the shaft 3 are attached between the vessels 10 and the carriage 2 respectively. A chute pivot shaft 5 is provided below the concrete discharge port 12, and a chute 6 pivotally attached to the chute pivot shaft 5 is attached to each chute pivot shaft 5 at a portion slightly closer to the center than one end. A dam concrete having a rotatable jack 7 attached to the chute 6 between a portion of the chute 6 closer to the other end than the chute pivot 5 and a fixed portion of the bogie 2 or the like. In carrier 1,
The concrete prepared in the batcher plant 50 is transported to a concrete receiving place 53.

That is, the dam concrete carrier 1
Is a dam concrete transport vehicle of the first invention of this application, and transports concrete prepared in the batcher plant 50 to the concrete receiving place 53 through the roadway 51 using the dam concrete transport vehicle 1.

Then, the concrete receiving place 53
Then, concrete is sequentially poured directly from the vessel 10 of the dam concrete transport vehicle via the chute 6 into the concrete bucket 52 that is landing on the concrete buckets 52 that are used.

The concrete is poured into the concrete bucket 52 first.
Is landed at a predetermined position by a transport device for the concrete bucket 52, in the illustrated example, a crawler crane 55. Then, the dam concrete transport vehicle 1 is positioned beside the concrete receiving place 53. Then, the positional relationship between the concrete bucket 52 and the dam concrete transport vehicle 1 is ensured at a predetermined level. At this point, the chute 6 is lowered and its tip is put into the concrete bucket 52, and then the vessel 10 is tilted. Lid 15
And the concrete in the vessel 10 is poured into the concrete bucket 52.

Two or more concrete buckets 52 are used. In the illustrated example, two concrete buckets 52, 52 are used. One of the concrete buckets 52 is transported by a crawler crane 55 described later and the remaining concrete buckets are placed. Although concrete is poured into the empty cocrete bucket 52, when three or more concrete buckets 52 are used, the concrete may be simultaneously poured into a plurality of concrete buckets 52 that have landed.

Then, the concrete bucket 52 into which the concrete has been poured is sequentially suspended and transported by a conventional suspension transporting means.

As the means for transporting the concrete bucket 52, various conventionally known hanging transport methods can be used. In this embodiment, a crawler crane 55 is used.
A hoistable wire (not shown) is hung from a crane arm 56 rotatable inside, and a hook (not shown) for detachably suspending the concrete bucket 52 is attached to the tip of this wire. It should be noted that this transporting means may be changed to a tower crane, a wire crane, or the like.

The concrete is transported by the dam concrete transport vehicle 1 in accordance with the transport cycle of the transport means. That is, while one concrete bucket 52 (hereinafter, referred to as an A bucket) is being transported and concrete is being placed, the remaining one concrete bucket (hereinafter, referred to as an A bucket).
It is called B bucket. Pour the concrete into). Then, the dam concrete transport vehicle 1 returns to the batcher plant 50 to transport the concrete again. Meanwhile, the crawler crane 55 finishes the concrete placement in the A bucket and replaces the empty A bucket with the concrete. It is returned to the receiving place 53, and then it is suspended on the B bucket and the casting of concrete is continued. Therefore, if the dam concrete carrier 1 returns with piles of concrete while the A bucket is empty and landed on the concrete receiving place 53, the empty A bucket is transported while the B bucket is being transported and concrete is being placed. Pour concrete into
Waiting for the bucket to finish and returning, the concrete is poured into this B bucket again, and the dam concrete carrier 1 returns to the batcher plant 50 and loads the concrete again.

By repeating the above operation, the transfer capacity of the crawler crane 55, in other words, the crawler crane 5
In accordance with the transfer cycle of No. 5, either the A bucket or the B bucket filled with concrete is always waiting at the concrete receiving place 53, so that the transfer capacity of the crawler crane 55 can be fully utilized. Become.

However, if the distance between the batcher plant 50 and the concrete receiving place 53 is long, the transport of the dam concrete transport vehicle 1 cannot keep up with the transport capacity of the crawler crane 55. As a countermeasure in this case, a method of increasing the number of concrete buckets 52 used to three or more, that is, a method of pouring concrete into the B bucket and the C bucket during the placement of the A bucket, and a method of dam concrete transport vehicle 1 In other words, two or more dam concrete transport vehicles 1 are prepared,
There is a method of increasing the transport amount by driving the vehicle on the road 51 so as to pass each other. Of the above methods, in the former case, the amount of concrete carried by the dam concrete transport vehicle 1 at a time is, of course, an amount that fills all of the prepared concrete buckets 52 with concrete, so that the number of concrete buckets 52 is simply increased. It is not possible to cope with this alone, and it is necessary to increase the transport capacity, and it is necessary to prepare three or more vessels 10 or to increase the capacity of the vessel 10 per one vessel. Therefore, in this embodiment, the latter is dealt with by increasing the number of used dam concrete transport vehicles 1.
That is, the capacity of the vessel 10 of the dam concrete transport vehicle 1 is made equal to the capacity of the concrete bucket 52, and the number thereof is selected according to the transport distance of the dam concrete transport vehicle 1, thereby increasing versatility and increasing the versatility. , It is possible to easily cope with the topographical conditions (mainly, the distance conditions of the roadway 51) at the construction site.

In the drawing, reference numeral 60 denotes an outrigger, and 61 denotes a vibrator.

[0043]

As described above, according to the present invention, since the plurality of vessels 10 are arranged in the front-rear direction of the self-propelled vehicle 1a, the concrete discharge port which usually has only one place in the batcher plant 50 can be used. By moving the self-propelled vehicle 1a forward or backward, the upper concrete inlet 11
Can be provided, and a concrete concrete transport vehicle capable of shortening the concrete loading time can be provided.

Further, in the present invention, since the vessel 10 is of a so-called side dump type, the position of the vessel 10 can be easily adjusted by moving the self-propelled vehicle 1a forward or backward. , The diameter of the lower portion of the vessel 10 is sequentially reduced downward, and
Since the chute 6 independent of the above is provided, it is possible to reliably and easily pour the concrete and to provide a dam concrete transport vehicle capable of shortening the pour time.

The present invention uses a concrete dam carrier capable of loading and pouring concrete as described above in a short time, and uses a plurality of concrete buckets for suspension. The following concrete can be prepared, and an efficient method of conveying dam concrete can be provided.
