Description

[Detailed Description of the Invention] <Technical Field> The present invention provides a working device that is placed on a sloped surface of a dam, a dam, etc. and performs, for example, asphalt paving work on the sloped surface. The present invention relates to a transport/operating device that supports and operates the working device at a top (referred to as a top), and also loads and transports the working device.

<Prior art> When performing work such as asphalt paving on a sloped surface of a dam, bulwark, etc. using a working device, the slope is so steep that there is a risk of the working device falling over or sliding down. It is supported and operated via ropes, etc.

A conventional example of such a device is shown in FIG. 1 (see Japanese Patent Publication No. 49-21932).

That is, a material carrier 2 that spreads materials such as asphalt paving material on the slope 1 and a construction device 3 that performs leveling, compaction, etc. of the spread material are connected to a roof 4 diagonally above the slope 1. From wire rope 5,6
It is supported so as to be movable in the vertical direction of the inclined surface 1 by a hoisting device 7 via. In addition, the material carrier 2 and the construction device 3 are moved, for example, in the left and right direction of the inclined surface 1 (first direction).
When moving to the back side or the front side of the figure, the material carrier 2 hoisted by the winch 8 of the hoisting device 7 is loaded onto the plate-shaped loading platform 7a, and then one end is moved as shown by the broken line in FIG. The material carrier 2 is placed above the main body of the hoisting device 7 by rotating the loading platform 7a at the center. Thereafter, the construction equipment 3 hoisted by the winch 9 is placed on the loading platform 7b that is overlapped with the aforementioned loading platform 7a, and the top 4 is moved together with the hoisting device 7 to the next work location.

However, in such a conventional device, since the loading platforms 7a and 7b are integrally attached to the main body of the hoisting device 7, for example, from the slope 1 to the top 4, or from the slope on the opposite side of the slope 1, When moving the material carrier 2 and the construction device 3 to the surface 1a, it is necessary to change the direction of the entire hoisting device 7 body.

By the way, in general, since the approximate width of the top field 4 is narrow, it is not possible to change the direction at that position. Work efficiency is poor because it is necessary to return to site 4. Furthermore, since the roof is often constructed with embankments, the strength of the roadbed is often weak, and if the hoisting device 7 is moved with the material carrier 2 etc. loaded, there is a risk that the road shoulder will collapse.

<Purpose of the invention> In view of the above-mentioned conventional problems, an object of the present invention is to provide a conveyance/operation device that allows easy loading and unloading of a slope working device in a sky.

<Structure of the invention> For this reason, the present invention includes a vehicle main body that can run, a step disposed above the vehicle main body for loading a working device, a support/operating section for supporting and operating the working device, and a step for loading the working device. The present invention includes a turning device disposed on the upper part of the vehicle body for turning the step and the support/operating section in a substantially horizontal plane.

<Example> Hereinafter, an example of the present invention will be described based on the drawings shown in FIGS. 2 to 8.

In FIGS. 2 and 3, crawlers 12 are attached to both sides of a frame 11, forming a vehicle body. Further, a main body frame 13 is provided above the frame 11, and this main body frame 13 and the frame 11 are connected by a turning device 14.

As shown in FIG. 4, the swing device 14 includes an annular inner ring 1 bolted to the upper surface of the frame 12.
5, and an internal gear 15a is formed on the inner peripheral surface of the inner ring 15. On the other hand, an annular outer ring 16 is bolted to the lower surface of the main body frame 13. The outer circumferential portion of the inner ring 15 is clamped to the inner circumferential portion of the outer ring 16 via a plurality of ball bearings 17 so as to be relatively rotatable. In addition, a hydraulic motor 18 with a reducer is installed at the bottom of the main body frame 13.
is attached, and a gear (not shown) attached to the rotating shaft of the hydraulic motor 18 is meshed with the internal gear 15a of the inner ring 15. Hydraulic pressure is supplied to the hydraulic motor 18 by operating a control panel in the driver's seat (not shown), and this causes the main body frame 13 to move around the pivot axis 1.
It is configured to rotate 360 degrees around point 3a.

A base end portion of a first step 19 on which construction equipment and the like are placed is rotatably attached to the front portion of the main body frame 13. As shown in FIGS. 5 and 6, the first step 19 includes a pair of hollow main body parts 19a attached to the main body frame 13, and a pair of hollow main body parts 19a that are slidably inserted into the hollow parts of the main body parts 19a. A movable part 19b is provided. Hydraulic cylinders 20 are attached to the inner side of the main body part 19a, and the rod tips of these hydraulic cylinders 20 are attached to the movable part 19b.
It is configured to protrude from the tip of 9a.
A pair of hydraulic cylinders 21 are each swingably attached to the main body frame 13, and the rod tips of these hydraulic cylinders 21 are swingably attached to a bracket 22 fixed to the lower part of the main body 19a. By operating the cylinder 21, the first

A pair of frames 2 are mounted on the upper part of the main body frame 13.
3 are erected at predetermined intervals, and a second step 25 on which, for example, a material carrier is placed, is attached to these frames 23 via a pair of links 24a, 24b. The second step 25 is the link 24a,
24b, and a pair of main body parts 25b attached to the bracket 25a and disposed above the first step 19.
It is formed from.

Here, the length of the link 24a rotatably attached to the upper part of the frame 23 is formed shorter than the length of the link 24b rotatably attached to the lower part of the frame 23, and each link 24a in the frame 23, The distance l ₁ between the pivot points of the movable bracket 24b is determined by the distance l 1 between the swinging fulcrums of the movable bracket 25a.
It is formed shorter than the distance l ₂ between the swinging fulcrums of b.

A hydraulic cylinder 26 is installed at the bottom of the frame 23.
The rod tips of these hydraulic cylinders 26 are attached to the lower part of the movable bracket 25a so that they can swing freely, and when the hydraulic cylinders 26 are operated, the second step 25 moves as shown by the chain line in FIG. As shown, it is configured to move above the first step 19.

Also, at the center of the rear part of the main body frame 13, a first winch 27 has a pair of wire ropes wound around it.
are rotatably attached, and these wire ropes are connected to a material carrier or the like placed on the second step 25. Further, second winches 28a and 28b, each having a wire rope wound thereon, are rotatably attached to the main body frame 13 on both sides of the first winch 27, and the wire rope is attached to a construction device placed on the first step 19. etc. 1st
The winch 27 and the second winches 28a, 28b are each rotationally driven by a hydraulic motor (not shown). First winch 27 and second winch 28
a and 28b constitute a support/operation section.

Next, the functions of this device will be explained based on FIGS. 7 and 8.

First, move the transport/operating device onto the inclined surfaces 29a, 29b.
The first step 19 and the second step 25 are oriented in the longitudinal direction of the ceiling 30 as shown by the chain lines in FIG. Then, a material carrier 31 for dispersing, for example, asphalt mixture onto the inclined surface 29a is driven along the ceiling 30 and placed on the second step 25.
After moving the second step 25 together with the first step 19 above the first step 19, a construction device 32 is placed on the first step 19 for leveling the spread asphalt mixture to a substantially uniform thickness. Further, the tip of the wire rope 31a pulled out from the first winch 27 is connected to the material transport vehicle 31, while the wire rope 32a pulled out from the second winches 28a, 28b is connected to the construction device 32.

After that, the main body frame 13 is rotated by the rotation device 14.
At the same time, the first and second steps 19 and 25 are rotated 90 degrees clockwise in FIG.
The movable part 19b of the step 19 is expanded and contracted, and the movable part 19b and the main body part 19a are swung in a vertical plane, so that the tip of the movable part 19b is grounded on the shoulder of the roof 30. Then, the construction device 32 is moved onto the inclined surface 29a while being supported by the wire rope 32a. Further, after the second step 25 is moved down and brought into contact with the first step 19, the material carrier 31 is moved onto the inclined surface 29a while being supported by the wire rope 31a. And material transport vehicle 3
The asphalt mixture spread from 1 is applied to construction equipment 3.
2 is moved up and down on the inclined surface 29a and leveled to a substantially uniform thickness to form an asphalt pavement layer.

After the work on the lane 33a extending in the vertical direction of the inclined surface 29a is completed in this way, the material transport vehicle 31 is lifted up by the first winch 27 and moved onto the second step 25, and the second step 25 is moved to the seventh step. The first step 19 is moved upward as shown by the broken line in the figure. Further, the construction device 33 is lifted up by the second winches 28a and 28b and moved onto the first step 19, thereby separating the first step 19 from the road shoulder.

Then, the support device is moved along with the material carrier 31 and the construction device 32 to the next lanes 33b and 3 above the roof 30.
These lanes 33b,
Perform work 33c. 34 is a material transport vehicle 31
There is a crane to supply materials.

In this way, in this embodiment, the first step 19
Since the second step 25 is rotated in a horizontal plane by the turning device 14, it is possible to easily load and unload material carriers 31, etc. at the ceiling 30, and the road width of the ceiling 30 is narrow. However, when moving the material transport vehicle 31 and the construction device 32 to the opposite slope 29b, for example, it is possible to move the material transport vehicle 31 and the construction device 32 to the opposite slope surface 29b without moving the transport/operating device to a flat area with a wide area.
It can be moved by simply rotating it 180 degrees, improving work efficiency.

In addition, if the roadbed strength of the roof 30 is weak, the first and second steps 19 and 25 are rotated 90 degrees as shown by the chain lines in FIG.
After unloading the material, only the transport/operating device is moved to the next lane, and the material transport vehicle 31 is further moved and loaded in steps 19 and 25 and moved onto the slope 29a, thereby reducing the load on the road shoulder. This reduces the risk of road shoulder collapse, etc.

Further, in this embodiment, the movable part 19b is made to protrude from the main body part 19a of the first step 19, and the main body part 19a and the movable part 19b are made to swing in a vertical plane, so that the slope of the inclined surface 29a is If the protrusion amount of the movable part 19b is different, the protrusion amount of the main body part 1
By adjusting the amount of swing of the movable portion 9a and the movable portion 19b, the inclination of the first step 19 and the inclination of the inclined surface 29a can be made to match, thereby facilitating loading and unloading of the material carrier 31.

In addition, the second step 25 is attached to the main body frame 13 by making the length of the upper link 24a shorter than the lower link 24b, and by making the distance between their swing fulcrums so that the main body frame side _l1 is shorter than the second step side _l2 . As a result, the second step 25 moves up and down in a substantially vertical direction as shown in FIG.
When material transport vehicles are loaded, the center of gravity between them and the support device hardly moves in the horizontal plane, which suppresses the occurrence of shaking of the transport and operation equipment, which also prevents road shoulder collapse, etc. can reduce the risk of

In this embodiment, the first and second steps 19,
25, two steps may be provided, but one step may also be used.
Moreover, three or more units may be used. Further, although the material transport vehicle 31 and the construction device 33 have been described as working devices, the present device can be applied to either one of them.

<Effects of the invention> As explained above, in the present invention, the step and support/operation part are rotated in the horizontal plane, so even when the road width at the top is narrow, it can be used without moving to a flat surface. The work equipment can be easily loaded and unloaded in one position, and by rotating 180 degrees, the work equipment can be moved to the opposite sloped surface, improving work efficiency. Further, for example, when the roadbed at the top of the road is weak, by loading and unloading the working equipment at that position, the load on the road shoulder can be reduced and the risk of the road shoulder collapsing can be reduced.
