Conventionally, in dam construction, a self-propelled cart called a transfer car is used when transporting raw concrete kneaded in a batcher plant and putting it into a concrete placement bucket. FIG. 6 is a diagram showing a configuration example of the transfer car. The transfer car 80 includes a carriage 82 to which wheels 81 are attached, a frame base 83 provided on the carriage 82, and a front upper side of the frame base 83. A vessel (hopper) 84 rotatably attached to the wheel 81, an electric motor 85 for rotationally driving an axle 81j fixed to the wheel 81, a vessel overturning jack 86 for rotating and tilting the vessel 84, and the vessel overturning A control device 88 that controls the hydraulic device 87 for extending the jack 86, the electric motor 85 and the hydraulic device 87 to control the fall of the vessel 84 and the traveling of the carriage 82, and a control signal to the control panel 88 A wire reel 89 around which a signal line and a power supply line for supplying electric power are wound, and a batcher plant (not shown) and a concrete placing bucket 9. There on rails R laid between the bucket storage 90 is placed, self-propelled on the basis of a control signal sent to the control board 88 via the wire reel 89.
The transfer car 80 that has received ready-mixed concrete at the batcher plant first travels on the rail R at a high speed and then decelerates at a predetermined position. Then, the transfer car 80 receives a predetermined position at the bucket storage 90 where the bucket 91 is placed. Stop at. Thereafter, the vessel overturning jack 86 attached to the transfer car 80 is extended to tilt the vessel 84, and the ready-mixed concrete mounted on the vessel 84 is put into the bucket 91. Thereby, the ready-mixed concrete accommodated in the vessel 84 can be replaced in the bucket 91.
The bucket 91 is suspended by a crane that transports the concrete to the concrete placement site of the dam, and the bucket 91 that stores the ready-mixed concrete is transported to the concrete placement site by the crane (see, for example, Patent Documents 1 to 3). ).

However, a conventional transfer car such as the transfer car 80 has a complicated structure because it needs to be equipped with an overturning mechanism (the vessel overturning jack 86, the hydraulic device 87, etc.) for rotating and tilting the vessel 84. In addition, there was a problem that it would become large.
Further, since it is necessary to mount the overturning mechanism below the vessel 84, the vessel 84 has to be installed on a frame base 83 provided on the carriage 82. As described above, if the vessel 84 containing ready-mixed concrete is installed at a high position from the upper surface of the carriage 82, the center of gravity of the transfer car 80 becomes high, and there is a concern about running stability.

  The present invention has been made in view of conventional problems, and it is an object of the present invention to reduce the size and weight of a cart for transporting ready-mixed concrete and to simplify concrete transport equipment.

  The invention according to claim 1 of the present application includes a rail stand installed between a batcher plant that supplies kneaded ready-mixed concrete and a bucket storage site provided at a position away from the batcher plant, and the rail stand. A concrete transportation facility comprising: a rail laid on the rail; and a transport carriage that has a hopper that accommodates the ready-mixed concrete supplied from the batcher plant and moves on the rail. A front wheel attached to the bucket storage side and a rear wheel attached to the batcher plant side, and the rail is divided into a front wheel rail on which the front wheel travels and a rear wheel rail on which the rear wheel travels. The rear wheel rail is laid so as to be positioned above the front wheel rail as it approaches the bucket storage side. It is characterized in that is. As a result, the hopper can be tilted without using a hopper tilting mechanism such as a tipping mechanism or a driving device such as a hydraulic device, so the transport cart can be reduced in size and weight, and the tipping mechanism and hydraulic device can be omitted. Can be constructed at low cost.

  The invention according to claim 2 is a rail stand installed between a batcher plant for supplying kneaded ready-mixed concrete and a bucket storage site provided at a position away from the batcher plant, and laid on the rail stand. A concrete transport facility comprising a rail and a transport cart having a hopper that accommodates ready-mixed concrete supplied from the batcher plant and moving on the rail, wherein the transport cart is the bucket storage site. A front wheel attached to the side and a rear wheel attached to the batcher plant side, and the rail is divided into a front wheel rail on which the front wheel travels and a rear wheel rail on which the rear wheel travels. The rear wheel rail has one end that is more bucketed than the position of the rear wheel when the carriage is stopped at a predetermined stop position on the bucket storage side. The first rear wheel rail, the other end of which is on the batcher plant side with respect to the rear wheel position, and the first rear wheel rail connected to the batcher plant side. A second rear wheel rail that extends, and the first rear wheel rail is pushed up above the front wheel rail below the first rear wheel rail of the rail base. A rail push-up mechanism is provided. As a result, there is no need to mount a mechanism for tilting the hopper such as a tipping mechanism or a driving device such as a hydraulic device mounted on the conventional cart on the transport cart, so the transport cart can be reduced in size and weight, and the transport cart can be reduced. The running stability of the vehicle can be improved. Moreover, since the inclination angle of the hopper can be arbitrarily set by using the rail push-up mechanism, the inclination angle of the hopper can be adjusted in accordance with the viscosity of the ready-mixed concrete accommodated in the hopper. Therefore, the ready-mixed concrete can be stably transferred to the bucket placed on the bucket storage site, and the work efficiency can be improved.

Hereinafter, the best mode of the present invention will be described with reference to the drawings.
Best Mode
1 and 2 are views showing a concrete transporting facility 1 according to the best mode 1 of the present invention. In each figure, 10 is a rail base, 20 is a rail, 30 is a transport cart, and 40 is a wire-type traction device. is there. In this example, a rail base 10 is constructed between the batcher plant 2 and the bucket storage 3, the rails 20 are laid on the rail base 10, and the ready-mixed concrete mixed in the batcher plant 2 is transported by the carriage 30. The transport cart 30 is pulled by the wire-type towing device 40 and moved from the batcher plant 2 to the bucket storage 3, and the ready-mixed concrete mounted on the transport cart 30 is mounted on the bucket storage 3. Transfer to the placed bucket 3a.
Hereinafter, the bucket storage 3 side is referred to as the front, and the batcher plant 2 side is referred to as the rear.

The rail platform 10 includes two rail support members 11 extending from the batcher plant 2 in the bucket storage 3 direction, and a plurality of support columns 12 that protrude from the ground G and support these rail support members 11 from below. And connecting members 13 and 14 for connecting the struts 12 to each other and extending from directly below the ready-mixed concrete supply hopper 2a that is provided at the lower portion of the batcher plant 2 and discharges ready-mixed concrete to the front of the bucket storage place 3. Two rails 20 are supported from below. The connecting member 13 is a connecting member that connects the columns 12 in the front-rear direction of the rail 20, and the connecting member 14 is a connecting member that connects the columns 12 or the connecting members 13 in the width direction of the rail 20. .
In this example, the height from the ground of the transport cart 30 when the ready-mixed concrete is mounted is different from the height from the ground of the transport cart 30 when the ready-mixed concrete is transferred to the bucket 3a. Therefore, the height of the column 12 of the rail base 10 is adjusted so that the rail 20 is provided with an inclined portion 20v between the batcher plant 2 and the bucket storage 3 where the height of the rail 20 gradually increases. is doing.
The bucket storage 3 is provided on the dam portion 4 of the dam already placed on one shore of the dam, and the bucket 3a is a cable crane (not shown) that conveys the bucket 3a to a concrete placement site. In the state suspended by the rope 3b, it is placed on the bucket storage place 3. When the bucket storage place 3 is a hole formed by excavating the ground G deeper than the height of the bucket 3a, a flat rail with no inclination is installed as the rail. On the other hand, when the depth of the hole of the bucket storage place 3 is limited as in this example, the height difference between the front and rear of the inclined portion 20v is adjusted to ensure the height at which the bucket 3a can be installed. No problem. Moreover, if the installation height of the rail 20 is set sufficiently higher than the upper surface of the bucket 3a, it is not necessary to form a hole in the bucket storage place 3.

The transport carriage 30 includes a transport hopper 31, axles 32p and 32q, front wheels 33p, rear wheels 33q, and first and second wire fixing portions 31p and 31q. The transporting hopper 31 is a box-shaped member that accommodates ready-mixed concrete mixed in the batcher plant 2 and that is open on the upper side. The axles 32p and 32q are respectively provided on the front side and the rear side of the two width side surfaces 31k of the transport hopper 31 so as to protrude outward in the width direction of the transport hopper 31 from the side surface 31k. In this example, the axle 32p of the front wheel 33p is attached to the lower front side of the side surface 31k, and the axle 32q of the rear wheel 33q is attached to the upper rear side of the side surface 31k. The front wheel 33p and the rear wheel 33q are rotatably attached to the front wheel axle 32p and the rear wheel axle 32q, respectively. The first and second wire fixing portions 31p and 31q are respectively provided on the front side and the rear side of the side surface 31k. Reference numeral 31n denotes a lid member provided on the front surface of the transport hopper 31.
In this example, the rail 20 is a double rail. That is, the rail 20 includes a front wheel rail 20p and a rear wheel rail 20q attached to the front wheel rail 20p. The front wheel rail 20p is located at a predetermined position in front of the bucket storage area 3. Change the direction downward and extend to end. On the other hand, the rear-wheel rail 20q is separated from the front-wheel rail 20p at the predetermined position, and extends and changes its direction upward and terminates. The predetermined position is a position separated from the end of the front wheel rail 20p on the bucket storage 3 side by a distance longer than the length of the transport cart 30 (for example, about twice the length of the transport cart 30). do it. Thereby, near the bucket storage place 3, the rear wheel rail 20q is positioned above the front wheel rail 20p. It should be noted that the angle between the position where the front wheel 33p of the front wheel rail 20p is placed and the position where the rear wheel 33q of the rear wheel rail 20q is placed and the horizontal direction at the planned stop position in the bucket yard 3 of the transport carriage 30 is It goes without saying that the end positions of the front wheel rail 20p and the rear wheel rail 20q are set so as to be equal to the inclination angle when the ready-mixed concrete is replaced with the bucket 3a.
Further, stopper portions 20k for preventing the front wheel 33p and the rear wheel 33q from deviating from the rails 20p and 20q are respectively provided at the end portions (terminal portions) of the bucket storage place 3 of the front wheel rail 20p and the rear wheel rail 20q. It is preferable to provide it.

The traction device 40 includes a wire 41 (41p, 41q) for towing the transport carriage 30, a winch 42 for winding and unwinding the wire 41, and a plurality of pulleys 43, 43a to guide the wire 41. 43c. In this example, two sets of traction devices 40 are provided.
As shown in FIG. 3, the winch 42 of the traction device 40 includes a cylindrical drum 42D provided with a wire guide groove 42k on the peripheral surface, an electric motor 42M connected to the drum 42D via a speed reducer 42G, An encoder 42S that is a rotation angle detecting means for detecting the rotation angle of the drum 42D, and a control device that controls the winding speed of the wire 41 by controlling the rotation speed of the electric motor 42M based on the output of the encoder 42S. (Not shown). The drum 42D is divided into two regions in the axial direction with the partition plate 42d as a boundary. When the wire 41p having one end fixed to the one region 42p is wound, one end is fixed to the other region 42q. The wire 41q is unwound.
Here, the wire 41p, the other end of which is fixed to the first wire fixing portion 31p, is a transfer wire that pulls the transport cart 30 from the batcher plant 2 to the bucket storage place 3, and the other end is the second wire. The wire 41q fixed to the wire fixing portion 31q is a return wire for returning the transport cart 30 from the bucket storage 3 to the batcher plant 2.
As shown in FIG. 3C, the transport wire 41p is pulled out to the front of the transport carriage 30, and the winch 42 is connected to the winch 42 via pulleys 43a and 43b provided on the front side of the rail base 10. It is fixed to one region 42p of each drum 42D. On the other hand, the return wire 41q is pulled out to the rear of the transport carriage 30 and is connected to one region 42q of each drum 42D of the traction device 40 via a pulley 43c provided on the rear end side of the rail base 10. Fixed to. Therefore, the transport cart 30 can be pulled forward by rotating each drum 42D of the traction device 40 in a direction in which the wire 41p for conveyance is wound.

Next, the operation of the transport cart 30 will be described with reference to FIG.
In the figure, the traction device 40 shows only the wires 41p and 41q, and others are omitted.
The transport cart 30 in which the ready-mixed concrete mixed in the batcher plant 2 (not shown) is mounted on the transport hopper 31 is separated from the position P where the front wheel rail 20p and the rear wheel rail 20q are separated by a predetermined distance L. Up to position Q, it is pulled by wire 41p and travels on rail 20 at a substantially constant speed. When the transport cart 30 reaches the position Q, the winding speed of the transport wire 41p is gradually reduced to decrease the travel speed of the transport cart 30.
When the transport carriage 30 passes the position P, the rail 20 is separated into a front wheel rail 20p and a rear wheel rail 20q, and the rear wheel rail 20q is positioned above the front wheel rail 20p. Therefore, the transport cart 30 moves forward slowly while gradually falling to the front side.
When the front wheel 33p and the rear wheel 33q reach the end portion of the front wheel rail 20p and the end portion of the rear wheel rail 20q, respectively, the winding operation of the wire 41p is interrupted and the transport carriage 30 is stopped. Since the stopper portions 20k are provided at the end portion of the front wheel rail 20p and the end portion of the rear wheel rail 20q, the transport carriage 30 does not deviate from the rails 20p and 20q.
In this stopped state, the transport hopper 31 of the transport cart 30 is inclined by a predetermined angle, so that the lid member 31n provided on the front surface of the transport hopper 31 is released to the lower side, and the transport hopper 31 The ready-mixed concrete is put into the bucket 3 a from the transport hopper 31. Thereby, the ready-mixed concrete can be easily transferred from the transport hopper 31 to the bucket 3a without using a hopper tilting mechanism.
The bucket 3a to which the ready-mixed concrete has been transferred is lifted by a crane (not shown) and conveyed to the concrete placement site.

As described above, in the best mode 1, the transport cart 30 that transports the ready-mixed concrete from the batcher plant 2 to the bucket storage place 3 includes the transport hopper 31 and the front side and the rear side of the side surface 31 k of the transport hopper 31. And a front wheel 33p and a rear wheel 33q that are rotatably attached to axles 32p and 32q provided so as to protrude outward in the width direction of the transport hopper 31, and the transport cart. The rail 20 on which the vehicle 30 runs is attached to the front wheel rail 20p and the front wheel rail 20p, and the rear wheel rail is terminated from the front side of the bucket storage 3 by changing its direction upward from the front wheel rail 20p. Since the double rail is provided with 20q, the hopper can be tilted without using the hopper tilting mechanism. Therefore, not only can the transport cart 30 be reduced in size and weight, but also the concrete transport facility 1 can be constructed at low cost.
In addition, since the carriage 30 is caused to travel on the rail 20 by the towing wires 41p and 41q fixed at one end to the winch 42 installed at the lower part of the rail base 10, a motor or the like The power equipment can be moved from the transport cart side which is a moving body to the rail base side which is a fixed portion. Therefore, the transport cart can be further reduced in size and weight.

In the best mode 1, the case where the transport cart 30 is pulled using the wire-type pulling device 40 has been described. However, the transport cart may be self-propelled. In this case, a motor may be mounted on the transport carriage 30 to drive the front wheel 33p or the rear wheel 33q, and the rear wheel 33q or the front wheel 33p to be a driven wheel.
In the above example, the rail 20 is a double rail in which the rear wheel rail 20q is attached to the upper side of the front wheel rail 20p. However, the front wheel rail 20p is installed on the inner side in the width direction, and the rear wheel rail is provided. 20q may be installed outside in the width direction. In this case, the position of the front wheel 33p and the position of the rear wheel 33q are appropriately set according to the rails 20p and 20q.
In addition, instead of the wire-type traction device 40, the transport cart 30 may be pulled using a chain-type traction device. In this case, a chain is used instead of the wire 41, the winch 42 is replaced with a driving sprocket, and the pulleys 43, 43a to 43c are replaced with driven sprockets. Similarly to the case where it is used, it is not necessary to mount power equipment on the transport cart 30, so that the transport cart 30 can be reduced in size and weight.

Best Mode 2
In the best mode 1, the rear wheel rail 20q is fixedly attached to the upper side of the front wheel rail 20p. However, as shown in FIG. 5, the rear wheel rail 20q is further connected to the first rear rail 20q. A rail push-up mechanism 50 that pushes the first rear wheel rail 20m upward from the front wheel rail 20p is provided, and the ready-mixed concrete is bucketed into a wheel rail 20m and a second rear wheel rail 20n. When moving to 3a, the carriage 30 may be tilted by pushing the first rear wheel rail 20m upward from the front wheel rail 20p. The method for towing the transport carriage 30 is the same as in the best mode 1 described above.
The front wheel rail 20p is disposed inside the rail 20 in the width direction, and the rear wheel rail 20q is disposed outside the rail 20 in the width direction. In response to this, the front wheel 33p is used for the front wheel by making the protruding length of the rear wheel axle 32q protruding from the side surface 31k of the transporting hopper 31 longer than the protruding length of the front wheel axle 32p. The vehicle travels on the rail 20p, and the rear wheel 33q travels on the rear wheel rail 20q.
The first rear wheel rail 20m has one end closer to the bucket storage 3 than the position of the rear wheel 33q when the transport carriage 30 stops at the stop position on the bucket storage 3 side, and the other end is the rear wheel 33q. It is located on the batcher plant 2 side from the position of. The second rear wheel rail 20n is connected to the first rear wheel rail 20m and extends to the batcher plant 2 side. The second rear wheel rail 20n is fixed to the rail base 10. However, the first rear wheel rail 20m is not fixed to the rail base 10, and one end of the rear wheel rail 20q is connected to the second rear wheel rail 20n by an opening / closing member 20x such as a hinge. The other end is rotatably attached in a plane that is parallel to the extension direction and perpendicular to the rail surface, and the other end is rotatably attached to the tip of an expansion / contraction lot 51b of a rail push-up mechanism 50 described later, for example, by a pin member. ing.

The rail push-up mechanism 50 rotatably supports the hydraulic jack 51 for tilting the rail, a hydraulic device (not shown) that drives the hydraulic jack 51, a jack holding member 52 that holds the hydraulic jack 51, and the jack holding member 52. And a rotation support member 53. The hydraulic jack 51 includes a cylinder 51a, a piston (not shown) provided in the cylinder 51a, and an expansion / contraction lot 51b attached to the piston.
The cylinder 51 a of the hydraulic jack 51 is held by a jack holding member 52, and this jack holding member 52 bridges the two connecting members 13 and 13 that extend in the front-rear direction, which is the extension direction of the rail 20. The rotation support member 53 provided on the connecting member 14 connected in the width direction of the rail 20 provided on the rotating member 53 is rotated in a plane parallel to the extension direction of the rail 20 and perpendicular to the rail surface by, for example, a pin member. It is attached as possible. On the other hand, the other end side of the expansion / contraction lot 51b is rotatably attached to the back side in the vicinity of the terminal portion of the rear wheel rail 20q by, for example, a pin member. By adopting such a configuration, if the expansion / contraction lot 51b is extended, the first rear wheel rail 20m can be rotated with the opening / closing member 20x as a fulcrum, so that the rear wheel rail 20q (actually The first rear wheel rail 20m) can be positioned above the front wheel rail 20p.

Next, the operation of the transport cart 30 will be described with reference to FIG.
In the figure, the traction device 40 shows only the wires 41p and 41q, and others are omitted.
A transport cart 30 in which ready-mixed concrete kneaded in a batcher plant 2 (not shown) is mounted on a transport hopper 31 is positioned near the boundary between the second rear wheel rail 20n and the first rear wheel rail 20m (for example, Up to the position of the symbol R in the figure, it is pulled by the wire 41p and travels on the rail 20 at a substantially constant speed. When the transport cart 30 reaches the position R, the winding speed of the transport wire 41p is gradually reduced to decrease the travel speed of the transport cart 30.
The first rear wheel rail 20m is already pushed up by the rail push-up mechanism 50 so as to be positioned above the front wheel rail 20p. At this time, the angle formed with the horizontal plane of the first rear wheel rail 20m is set so that the inclination angle of the transport carriage 30 at the stop position becomes a preset angle.
From the time when the rear wheel 33q of the transport cart 30 is placed on the first rear wheel rail 20m, the transport cart 30 moves forward slowly while gradually falling forward and then stops. In this state, since the inclination angle of the transport carriage 30 is a preset angle, the ready-mixed concrete in the transport hopper 31 can be transferred to the bucket 3a (not shown).

In this manner, the rear wheel rail 20q is divided into the first rear wheel rail 20m and the second rear wheel rail 20n, and the first rear wheel rail 20m is separated by the rail push-up mechanism 50. Since the inclination angle of the transport carriage 30 can be arbitrarily set by pushing up above the rail 20p, the inclination angle of the hopper is adjusted according to the viscosity of the ready-mixed concrete accommodated in the transport hopper 31. Can be adjusted.
In the above example, the rear wheel rail 20q is divided into a first rear wheel rail 20m and a second rear wheel rail 20n, and the first rear wheel rail 20m located on the bucket storage 3 side. However, the front wheel rail 20p may be divided into two, and the rail located on the bucket storage 3 side may be pulled down below the rear wheel rail 20q.

  As described above, according to the present invention, the hopper for transporting concrete can be tilted without using the hopper tilting mechanism, so that the transport cart can be reduced in size and weight and the concrete transport facility can be simplified. Can do.
