[Structure of the Invention] The slope paving device according to the present invention includes a traveling bogie that runs on rails laid along a horizontal surface adjacent to the slope to be paved, and an elevation angle on the traveling bogie that can be arbitrarily adjusted. a beam device whose length can also be adjusted; a finisher which can be suspended from the tip of the beam device and is swingably supported; It consists of a conveyor whose length is adjustable so that it can be positioned close to the conveyor.

[Operations and Effects of the Invention] Therefore, since the asphalt mixture supply device is provided, workability can be improved.
Furthermore, it can be used even if the radius of curvature of the inclined surface is small.
Moreover, even if a speed difference occurs between the finisher and the truck, this difference can be absorbed. Further, an extendable conveyor is installed from the traveling vehicle to the asphalt finisher, so that the asphalt mixture is conveyed from the hopper on the traveling vehicle to the finisher and supplied to the slope to be paved. Further, in carrying out the present invention, it is preferable that the traveling carriage is supported by wheels rolling on rails and guided by a pair of auxiliary wheels that sandwich the rails. By providing auxiliary wheels in this way, it is possible to receive the horizontal force acting on the bogie, absorb the speed difference between the bogie and the finisher, and prevent derailment even if the radius of curvature of the bogie is small.

The frame body 41 includes support rods 45, 45 vertically installed at intervals on the underframe, a pair of diagonal rods 46, 46 that support these support rods, and a connecting rod 47 that connects the tops of the support rods. It consists of Guide pulleys 48, 48 are provided at the tops of the support rods 45, 45, and hydraulic winches 49,
It is adapted to guide wires 50, 50 being fed out from 49.

The pair of beams 43, 43 are formed into a unit and can be added to, and a pair of brackets 54, 54 are slidably provided at the tips thereof, and these brackets are connected by a horizontal rod 51. The horizontal rod 51 and therefore the arm device are supported by wheels 53. Pulleys 55, 55 are pivotally connected to these brackets, and wires 50,
50, these pulleys 55, 55 and struts 45
They are respectively hung around pulleys 56, 56 which are similarly pivoted at the tips of the. Therefore, when the hydraulic winches 49, 49 are appropriately driven in synchronization, the wires 50, 50 are reeled in or rewound, and the beams 43, 43 can assume a predetermined elevation angle. Brackets 54, 54 to which horizontal rods 51 are fixed
Piston rods 57, 57 of hydraulic cylinders that operate telescopically are also pivotally connected to the cylinders 58, 58, and the cylinders 58, 58 are swingably attached to the beams 43, 43. Therefore, when pressure oil is supplied and discharged from the hydraulic cylinder, the horizontal rod 51 moves up and down, and this horizontal rod 5
The finisher 20 attached to 1 can be moved and adjusted in the diagonal direction of the inclined surface.

The conveyor that conveys the asphalt mixture from the truck 1 to the finisher 20 is a screw conveyor 60 in the embodiment. This conveyor is supported by a support frame 61 having a truss shape.
The end of the support rod 61 is pivotally connected to the bracket 62 of the underframe 9 by a pin 63, the piston rod 65 of the hydraulic piston unit 64 is pivotally connected approximately in the middle, and the base of the cylinder 66 is pivotally connected to the end of the truck 1. It is pivotally supported. Therefore, the hydraulic piston unit 64
By appropriately operating the support frame 61, the support frame 61 can take any desired angle of inclination. Therefore, the conveyor 60 supported by the support frame 61 can also be tilted at an arbitrary angle.

The asphalt mixture supplied to the hopper 70, which is provided on the opposite side of the beam device 40 in consideration of balance, is conveyed upward and supplied to the second conveyor 68. It's becoming like that. For this purpose, the feed section of the second conveyor 68 is located below the end of the first conveyor. Further, the second conveyor 68 is slid by chains 72 and 73 driven by a slide hydraulic motor 71, and when the second conveyor 68 slides, the end portion of the first conveyor 67, that is, the discharge portion 74 and the second conveyor 68 supply will be misaligned. Therefore, in this embodiment, although not shown in detail, the position of the supply section is also changed in accordance with the slide of the second conveyor. The configuration for this purpose is well understood by those skilled in the art, so a detailed explanation will be omitted, but a part of the cylindrical casing that houses the screw is cut out, and a lid body that covers this cutout part is made slidable. , the position of the supply section can be changed. Of course, the terminal end 75 of the second conveyor 68 faces the hopper of the finisher 20. Further, the screw 76 of the second conveyor is driven by a hydraulic motor 77. Note that the conveyance capacity of the second conveyor 68 is the same as that of the first conveyor 68.
It is somewhat larger than that of conveyor 67.

Rails 3, 3 are laid along the slope B to be paved and on a flat land C adjacent to the slope B. Then, place trolley 1 on the rail. In the beam device 40, hydraulic motors 49, 49 are driven to maintain the beam device at a required angle and move the cart 1. Move the beam 43 so that the finisher 20 is in the paving work position.
Of course, you can adjust it by adding or removing it. Note that fine adjustment of the finisher 20 in the direction along the inclination line can be performed by hydraulic devices 58, 58.

After the above preparations are completed, the asphalt mixture is supplied to the hopper 70 on the truck 1, and the first conveyor 67 and the second conveyor 68 are driven. At the same time, the truck 1 and the finisher 20 are driven synchronously. Then, the asphalt mixture is conveyed from the hopper 70 to the finisher 20, and then supplied to the slope B. Therefore, the asphalt mixture is rolled out onto the slope by the finisher 20. Thus it is paved.

[Summary] As detailed above, according to the present invention, since the cart is provided with a conveyor that reaches the finisher, the supply of asphalt mixture can be synchronized with the running of the finisher, and furthermore, the conveyor that reaches the finisher can be synchronized with the conveyor. Since a trolley is used to move the equipment, it can be provided at an extremely low cost compared to conventional equipment using a tractor.
