Description

[Detailed description of the invention] [Industrial application field] This invention is equipped with a finisher used for paving slopes and a damper truck for supplying paving material, and is used to change the top and bottom of slopes in order to change the paving lane. Regarding a self-propelled winch porter.

[Prior Art] In order to pave long slopes such as embankments and dams, a finisher, such as an asphalt finisher, which moves the slope from the lower end to the upper end to pave the slope, and a reciprocating machine up and down the slope are used. A damper truck is used that moves and supplies paving material, such as asphalt mix, to the finisher. To change the paved lane, a dolly called a winch porter that moves on its own at the top of the slope is used, and the winch porter has separate winches that move the finisher and damper vehicle up and down the slope. It is also equipped with a deck on which to mount a finisher and damper vehicle when changing paved lanes.

By the way, conventional winch porters have a structure in which the finisher and damper car are mounted on a deck in tandem, or the deck has a double structure, and the deck for the damper car is lifted by a hydraulic cylinder to create space for the finisher at the bottom. It was becoming.

[Problems to be Solved by the Invention] However, in the case of the former type of winch porter, it is necessary to increase the length of the deck, which necessitates increasing the size of the entire device. In addition, when using the latter type of winch porter, the structure is complicated and the manufacturing cost is high, and the damper truck is mounted on a flat deck, which causes instability when moving the winch porter. Therefore, it was necessary to secure the damper vehicle with wire ropes, etc.

The present invention was developed to solve the above-mentioned drawbacks of conventional winch porters, and by effectively mounting the finisher and damper vehicle in a narrow area, the winch porter can be made smaller and the manufacturing and transportation costs of the device can be reduced. In addition, the present invention has been made to provide a winch porter for paving a slope surface that can be easily used even in a site where the surface of the slope surface is narrow.

[Means for Solving the Problems] Therefore, according to the present invention, the finisher 2 moves the slope A from the lower end to the upper end to pave the slope A, and the finisher 2 moves the slope A up and down to reciprocate to pave the slope A. It is equipped with inclined decks 4a and 4b on which damper cars 3 for supplying material to the finisher 2 are mounted, and the finishers 2 and damper cars 3 are mounted on the decks 4a and 4b.
In the winch porter 1, which is equipped with a lift arm 13, which is mounted on the deck 4a of the winch porter and is rotated vertically about a pin 11 by a hydraulic cylinder 12, is mounted on the deck 4a of the winch porter and moves by itself on the top B of the slope A to change the paving lane. A winch porter for paving a slope surface is provided, and the tip of the lift arm 13 is an engagement recess 13a that engages with the axle 3a of the damper vehicle 3.

[Operation of the invention] The finisher 2 and damper car 3 are moved on the slope A, the damper car 3 supplies paving material to the finisher 2, and the finisher 2 pavers the slope A. In order to move the finisher 2 and the damper truck 3 to the next lane when the paving has been completed to the top of the slope A, the damper truck 3 is first pulled up onto the deck 4a of the winch porter 1, and the lift arm 13 is operated by the hydraulic cylinder 12. Then, the engagement recess 13a provided at the tip of the lift arm 13 is engaged with the axle 3a of the damper car 3 to lift the damper car 3 upward, and by lifting the damper car 3, the finisher is moved to the space opened above the decks 4a and 4b. Equipped with 2. Next, winch porter 1
The vehicle moves on its own and changes lanes.

[Effects of the invention] As described above, even with the simple configuration of installing a lift arm operated by a hydraulic cylinder on the deck of the winch porter, the finisher and damper vehicle can be mounted effectively in the narrow deck space. It can be made smaller, reducing production and transportation costs. It can also be used in sites where conventional large winch porters cannot be used, such as when the width of the sky is narrow or when there is a slope C on the opposite side of the sky.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2.

In these figures, A is the slope to be paved, B
indicates the sky, and C indicates the slope. The equipment can be roughly divided into Tenba B.
A winch porter 1 that moves by itself, an asphalt finisher 2 that moves from the lower end to the upper end of the slope A to pave the slope A, and an asphalt finisher 2 that moves up and down the slope A to pave the slope A. The damper car 3 supplies the damper.

The winch porter 1 includes an inclined deck, and in the illustrated embodiment, a lower deck 4b connected to an upper deck 4a by a pin 5 and rotated upward by a hydraulic cylinder 6. Near the top end of the upper deck 4a is a lower deck 4b. A front wheel stopper 7 of the damper vehicle 3 is provided. The winch porter 1 is also provided with separate winches 8 for moving the asphalt finisher 2 and the damper vehicle 3 on the slope A (only one of them is shown in FIG. 1). The wire rope 9 is connected to the asphalt finisher 2 and the damper car 3 via a sheave 10 provided at the top end of the upper deck 4a. A lift arm 13 is provided approximately in the middle of the deck 4a, which is connected by a pin 11 and rotated up and down by a hydraulic cylinder 12, the tip of which engages with the rear axle 3a of the damper wheel 3. This is an engagement recess 13a.

Next, how the device is used will be explained.

The winch porter 1 is placed at the top B of the slope A. The asphalt finisher 2 and the damper car 3 are each supported by wire ropes 9 of separate winches 8. At the beginning of paving, the asphalt finisher 2 is set at the lower end of the slope A, and is pulled up by the winch 8 and moved above the slope A while paving a certain width. The damper truck 3 has a winch 8 separate from the asphalt finisher 2.
The asphalt composite material is supplied to the asphalt finisher 2 by reciprocating up and down the inclined surface A.

In order to move the asphalt finisher 2 and the damper truck 3 to the next lane when the paving is completed to the top, the damper truck 3 is first pulled up onto the deck 4a of the winch porter 1, and the hydraulic cylinder 1
2 to raise the lift arm 13, engage the engagement recess 13a provided at the tip of the lift arm 13 with the rear axle 3a of the damper wheel 3, and move the lift arm 9 from the position indicated by the dotted line in FIG. By rotating the damper vehicle 3 upward to the position indicated by the solid line, the front wheel 3b of the damper vehicle 3 is stopped by the stopper 7, lifted upward, and fixed. Then, by lifting the damper car 3, the asphalt finisher 2 is mounted in the space created on the deck 4a. Next, the lower deck 4b is connected to the hydraulic cylinder 6.
By rotating the winch porter 1 upward from the position shown by the solid line in FIG. 2 to the position shown by the dotted line, the winch porter 1 can move by itself and change lanes.
