Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a slope construction device for constructing a slope surface such as a running track of a velodrome or an automobile driving test range.

<Prior art> Since the running track of a velodrome or an automobile driving test range is formed on an inclined surface, when paving the slope with asphalt, for example, an asphalt finisher is run on the slope to level the asphalt mixture. That's what I do. At this time, the following measures have been taken to prevent the asphalt finisher from slipping and falling.

That is, as shown in Japanese Patent Publication No. 48-7296,
There is a system in which an asphalt finisher disposed on a slope is supported by a tractor disposed on a flat portion below the slope via a support rod, and the asphalt finisher and the tractor travel together.

<Problems to be Solved by the Invention> However, in such conventional inclined surface working equipment, the asphalt i-finisher on the inclined surface is supported by a tractor via a support rod, so that the asphalt mixture is When supplying the asphalt mixture to the asphalt finisher, it is necessary to lower the asphalt finisher from the slope and supply the asphalt mixture, or to supply it by another belt conveyor, resulting in a problem of poor leveling work efficiency.

Furthermore, as shown in Japanese Patent Publication No. 63-58962, there is a system in which a beam device is extended from a cart disposed on a flat portion below an inclined surface, and its tip is positioned at the top. The asphalt finisher is suspended and supported by a wire from the tip of the beam device, and the asphalt mixture is supplied from the truck to the asphalt finisher by a conveyor.

However, since the tip of the beam device is placed on the top end of this device, there is a problem that the arrangement and assembly work thereof becomes complicated.

Furthermore, since the conveyor is attached to the beam device, there is a problem in that the assembly work is complicated.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a slope construction device that can improve the efficiency of assembly and installation work.

<Means for Solving the Problems> Therefore, the present invention provides a vehicle that runs along a flat portion on the side of the slope along the slope, and a vehicle that has one end attached to the vehicle and runs on the slope. A support rod for supporting a working device that performs work on the slope, and a conveyance device that is attached to the vehicle at a different attachment position from the attachment position of the support rod and that conveys and supplies the material to be conveyed. I made it.

This second bar conveyor 11 has the same structure as the first bar conveyor 7, so a description thereof will be omitted. A plate-shaped second drag pan 12 is attached below a chain belt (not shown) of the second bar conveyor 11 along the chain belt. Openings 12A, 12B, and 12C for dropping the asphalt mixture are opened at predetermined intervals in the second drag pan 12, and these openings 12A, 12B, and 12C are connected to gates (not shown) driven by hydraulic cylinders (not shown). ) can be selectively opened and closed. Further, on both sides of the second drag pan 12, plate-shaped frames (
(not shown) are attached to cover the sides of the chain belt. Here, a motor (not shown) for driving the second bar conveyor 11 is configured to be able to rotate in forward and reverse directions '14, so that the conveyance direction of the second bar conveyor 11 can be switched.

A hopper 13 for storing an asphalt mixture is attached to the rear part of the frame 1. This hopper I3 is provided with a pair of lid parts 13A that spread laterally, and these lid parts 13A cover the upper part of the hopper 13 as shown in FIG. It seems to be expanding to both sides. A front end portion of a feeder 14 made of bar conveyor hair is disposed below the hopper 13, and a rear end portion of the feeder 14 is disposed above the front end portion of the first bar conveyor 7.

Here, as shown in FIG. 3, the hopper 13 and the feeder 14 are attached to the frame l so as to be freely rotatable in a substantially vertical plane, and the hopper 13 and the feeder 14 are substantially connected to each other by a third hydraulic cylinder 15. It is designed to rotate in a vertical plane.

The asphalt mixture in the hopper 13 is supplied from the feeder 14 to the first parcon hair 7 and then to the second parcon hair 11.

As shown in FIGS. 1 and 4, a bracket 1-16 is attached to the frame 1 on the side of the crawler 2 and extends in the longitudinal direction of the vehicle. One end of a support rod 17 is attached to the center of the bracket 16 so as to be freely rotatable in a substantially vertical plane and to be detachable, and the support rod 17 extends in a direction substantially perpendicular to the direction in which the vehicle travels. One end of a support member 18 is attached to the front and rear of the bracket 16 so as to be able to rotate freely in a substantially vertical plane, and the other end of these support members 18 is attached to the middle part of the support rod 17 for support. Swinging of the rod 17 in the longitudinal direction of the vehicle is suppressed.

Further, a fourth hydraulic cylinder 19 is attached to the bracket 16 so as to be able to rotate freely in a substantially vertical plane, and a piston rod of the fourth hydraulic cylinder 19 is attached to an intermediate member of the support rod 17, so that the support rod 17 is rotated approximately vertically. It is designed to rotate within the plane. Here, the support rod 17 is constructed by removably connecting a plurality of members so that its effective length can be changed.

The other end of the support rod 17 is connected to the side of an asphalt finisher 20 as a working device via a ball joint (not shown). Further, the tip of the second barcon hair 11 is located on one side of the hopper 21 of the asphalt finisher 20.

Here, the first bar conveyor 7 and the second bar conveyor 11
constitutes the transport device.

Next, the action will be explained.

First, after attaching one end of the support rod 17 to the frame 1,
The other end of the support rod 17 is connected to the side of the asphalt finisher 20 via a ball joint.

Then, the asphalt finisher 20 is run on the slope A while being supported by the support rod 17 to prevent it from slipping down, and the asphalt finisher 20 is moved along the slope A. The device is run on a flat part below the slope A in a direction substantially parallel to the plane A.

The asphalt mixture is then conveyed and supplied from the hopper 13 to the hopper 21 of the asphalt finisher 20 via the feeder 14 and the first and second bar conveyors 7.11. The asphalt finisher 20 spreads the supplied asphalt mixture on the slope A.

Moreover, after the rug is finished, the support rod 17 is attached and the second percon hair 11 is moved below the first bar conveyor 7. Then, the first and second bar conveyors 7.11 are rotated by the turning device 3 and positioned above the hopper 13.

As explained above, the first and second bar conveyors 7.1
1 is attached to the upper part of the frame main body 4 above the frame 1, and the support rod 17 is attached to the side of the frame 1. This prevents the asphalt finisher 20 from sliding down and efficiently transfers the asphalt l-mixture to the asphalt finisher 20. They can be supplied and leveled, and their installation and assembly work can be greatly simplified compared to conventional ones, and their work efficiency can be greatly improved.

Also,! Since the second percon hair 11 can be moved in the conveyance direction of the first bar conveyor 7, by moving the second bar conveyor 7, the asphalt mixture can be selectively transferred from the second bar conveyor 11 to a wide range of locations (positions). Can be supplied by falling. In particular, the second drag pan 12 of the second bar conveyor 11 is provided with three openings 12A-12C.
Since the asphalt mixture is selectively dropped and supplied to the asphalt finisher 20 from 12C, the asphalt mixture can be transported and supplied to a wider range of locations.

In addition, since the first and second drag pans 8.12 are provided on the first and second bar conveyors 7.11 and the chain belts are covered by frames on both sides of the drag pans, the asphalt mixture is transferred to the first and second bar conveyors 7.11 during conveyance. Spillage from the second conveyor 7.11 can be prevented.

Moreover, after the rug is finished, the second bar conveyor 11 is positioned below the first bar conveyor 7, and is rotated by the turning device 3 to be placed above the hopper 13 in the longitudinal direction of the vehicle. As a result, the equipment is compact and can be started up to other construction sites using a single large trailer.

Note that the second bar conveyor 11 may be rotated about the tip of the first bar conveyor 7 in a substantially horizontal plane. Further, the conveying device may be used for conveying and supplying other than asphalt finishers.

<Effects of the Invention> As explained above, in the present invention, the support rod that supports the working device by the support rod and the conveyance device are installed separately on the vehicle, so that the installation work and assembly work thereof is simplified. can be significantly improved over the conventional example.
