BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle with a crane, which is provided with a cabin, a material support member and a crane in order from a front part to a rear part of a vehicle body and is used for loading and carrying wood, for example.

[0002]

2. Description of the Related Art As a conventional carrier with a crane, for example, there is one disclosed in Japanese Utility Model Publication No. 61-2105. That is, the crane mounted on the bed of the vehicle is fixed with the boom member folded and tilted with respect to the bed at the time of storage, and in the fixed state, the upper ends of the column and boom member exceed the allowable vehicle width and the allowable vehicle height. There is no such thing.

Further, as a conventional carrier with a crane,
For example, there is one disclosed in JP-A-1-317996. That is, the center of gravity is lowered and the traveling is stabilized by tilting and turning the swinging / elevating arm of the crane.

[0004]

However, in the conventional vehicle with a crane, when moving up or down a steep slope, the center of gravity of the vehicle body is not sufficiently moved in the front-rear direction.
There was a problem that the driving stability was not good.

The present invention has been made in view of such conventional problems, and provides a crane-equipped carrier vehicle capable of enhancing the traveling stability when climbing or descending a steep slope. The purpose is to do.

[0006]

In order to achieve the above object, a carrier with a crane according to the present invention of claim 1 is provided with a cabin, a cargo support member, and a crane in a vehicle body in order from a front part to a rear part. A vehicle with a fixed crane,
The crane is characterized in that its supporting column is tiltable in the vehicle front-rear direction by power, and its supporting column base is attached to the rear part of the vehicle body.

The power for tilting the crane may be hydraulic power, electric power, or any other power. The crane may have a collection clip, a hook, a backhoe, or any other attachment attached at its tip. The carried object support member may be made of any member as long as it is a member for placing and supporting a carried object thereon.

According to a second aspect of the present invention, there is provided a crane-equipped carrier vehicle according to the first aspect, wherein the cabin is attached to a front portion of the vehicle body so as to be slidable in a vehicle front-rear direction by power. It is characterized by

According to a third aspect of the present invention, there is provided a crane-equipped carrier vehicle according to the first or second aspect, wherein the outrigger has its legs extending in the opposite direction to the crane columns by power. It is attached to.

A transport vehicle with a crane according to a fourth aspect of the present invention is the transport vehicle with a crane according to the first, second or third aspect, wherein the vehicle main body includes a hydraulic device having a hydraulic coupler. It has a hydraulic drive winch that is movable and connectable to the hydraulic coupler.

[0011]

In the transport vehicle with a crane according to the first aspect of the present invention, a cargo such as wood can be loaded and transported on the cargo support member by the crane. When climbing a steep slope, the prop of the crane is tilted toward the front of the vehicle by power. For example, when climbing a mountain to load felled wood, the crane can be tilted forward without being obstructed by the timber because the timber support member is not yet loaded with timber. This allows
The center of gravity moves to the front side of the vehicle body, making it easier to climb a slope.

When going down a slope, the pillars of the crane are tilted toward the rear of the vehicle body by power. The crane is attached to the rear part of the vehicle body, and when moving down, the center of gravity can be easily moved toward the rear part of the vehicle body. Therefore, for example, when felling timber is loaded and descended from the mountain, the weight of the timber loaded increases, but tilting the crane toward the rear moves the center of gravity toward the rear of the vehicle, making it easier to balance. Become.

In the vehicle with a crane according to the present invention of claim 2, when climbing a fairly steep slope, the crane is tilted toward the front of the vehicle and the cabin is slid toward the front of the vehicle by power. As a result, the center of gravity moves further toward the front of the vehicle body, and it becomes easier to stably climb the slope. When going down a fairly steep slope, the crane is tilted toward the rear of the vehicle and the cabin is powered to slide toward the rear of the vehicle. As a result, the center of gravity moves further toward the rear part of the vehicle body, and it becomes easier to stably descend the slope.

In the carrier with a crane according to the third aspect of the present invention, when the crane work is performed on a slope, the outrigger also rises in the vertical direction when the prop of the crane is vertically raised by power. Since the outrigger supports the crane in the vertical direction, no force is applied in the bending direction and it is hard to break. The outrigger not only stabilizes the turning of the crane but also acts as a brake for the crane-equipped carrier during work.

In the transport vehicle with a crane according to the fourth aspect of the present invention, for example, a transported material such as felled wood can be moved by a hydraulic drive winch. The hydraulic drive winch can be used separately from the vehicle body. Also, the hydraulic drive winch can be removed from the hydraulic coupler and completely separated from the vehicle body. Therefore, once the load is loaded on the load support member, the hydraulic drive winch can be moved as it is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 5 show an embodiment of the present invention. As shown in FIG. 1, a crane-equipped transport vehicle 10 includes a vehicle body 11, a cabin 12, and a transported object support member 13.
, A crane 14, a pair of outriggers 15, hydraulic drive winches 16 and 17, and a hydraulic device (not shown).

The vehicle main body 11 is a tracked vehicle (carrier dump truck) and is easy to travel on a mountain road. A rail is fixed to the upper portion of the vehicle body 11. The cabin 12 is attached to the front portion of the vehicle body 11 so as to be engaged with the rails and slidable in the vehicle front-rear direction. A cylinder portion of a hydraulic cylinder for moving the cabin is fixed to an upper portion of the vehicle body 11, and a piston portion of the hydraulic cylinder is fixed to a bottom portion of the cabin 12. This hydraulic cylinder is connected to a hydraulic coupler of a hydraulic device and can expand and contract by hydraulic pressure. As a result, the cabin 12
It is possible to move in the vehicle front-back direction by expanding and contracting the hydraulic cylinder for moving the cabin. The cabin 12 is provided with a driver's seat 12a of the vehicle body 11.

A pair of article support members 13 are provided in front of and behind the vehicle body 11 between the cabin 12 and the crane 14. Each cargo support member 13 has two poles 21.
Are connected by a base member so as to be parallel to each other. This base member is fixed to the upper part of the vehicle body 11,
The two poles 21 of each cargo support member 13 are the vehicle body 1
It is erected on both sides of the upper part of 1. On the pair of transported object support members 13, an elongated transported object such as wood can be sandwiched between the poles 21 and placed.

The crane 14 has a pillar base 22 and a pillar 23.
Is fixed, the first boom 24 is rotatably attached to the column 23, the second boom 25 is rotatably attached to the first boom 24, and the third boom 26 is rotatably attached to the second boom 25. . The third boom 26 is the telescopic arm 2
7, and a gripping tool (grapple) 28 for collecting material is attached to the tip of the telescopic arm 27. In the pillar 23,
A cockpit 29 of the crane 14 is provided. The crane 14 is connected to a hydraulic coupler of a hydraulic device, and can bend each boom 24, 25, 26, extend the telescopic arm 27, and open and close the collecting clip 28.

The lower portion of the column base 22 of the crane 14 is rotatably attached to the rear portion of the vehicle body 11 by a shaft 31. A cylinder portion of a hydraulic cylinder for tilting a crane is fixed to a rear portion of the vehicle body 11, and a piston portion 32 of the hydraulic cylinder is rotatably attached to a lower end of a column base 22 by a shaft 33. This hydraulic cylinder is connected to a hydraulic coupler of a hydraulic device and can expand and contract by hydraulic pressure. As a result, the crane 14 can be tilted in the vehicle front-back direction by expanding and contracting the crane tilting hydraulic cylinder.

Each outrigger 15 has a cylinder portion 34.
And a piston portion 35 and a leg portion 36. The outrigger 15 is connected to a hydraulic coupler of a hydraulic device, and a piston portion 35 can be hydraulically expanded and contracted with respect to a cylinder portion 34. The leg portion 36 is the piston portion 35.
It is attached so that it can be bent. The piston portion 35 and the leg portions 36 of the cylinder portion 34 are the crane 1
The column 4 is fixed to the column base 22 so as to extend in the direction opposite to the column 23.

The hydraulic drive winch 16 is movable from the vehicle body 11 and can be connected to the hydraulic coupler of the hydraulic system. The hydraulic drive winch 17 is fixed to the column base 22 of the crane 14 and is connected to the hydraulic coupler of the hydraulic system. The hydraulic device includes a plurality of hydraulic couplers and is provided in the vehicle body 11.

Next, the operation will be described. As shown in FIG. 2, when climbing a steep slope with the crane-equipped carrier 10,
The piston portion 32 of the hydraulic cylinder for tilting the crane is extended, the crane 14 is rotated about the shaft 31, and the column 23 of the crane 14 is tilted toward the front of the vehicle body. The booms 24, 25, 26 of the crane 14 are bent in advance. When climbing a mountain to load felled wood,
Since the timber is not yet loaded on the cargo support member 13, the crane 14 can be tilted forward without being obstructed by the timber. As a result, the center of gravity moves to the front side of the vehicle body, which enhances the stability of traveling and makes it easier to climb a slope. Further, by inclining the pillars 23, it is possible to reduce the height of the crane 14 and prevent the upper end from exceeding the allowable vehicle height.

If the slope is fairly steep, the crane 14
Is tilted toward the front of the vehicle, and the cabin 12 is slid toward the front of the vehicle by the hydraulic cylinder for moving the cabin. As a result, the center of gravity moves further toward the front of the vehicle body, and it becomes easier to stably climb the slope.

When loading wood on a mountain slope,
As shown in FIG. 3, the piston portion 32 of the crane tilt hydraulic cylinder is expanded and contracted to rotate the column base 22, and the column 23 of the crane 14 is raised in the vertical direction. This allows
The outrigger 15 also rises vertically. In this state, the piston portion 35 is extended from the cylinder portion 34 of the outrigger 15 and the leg portion 36 is pressed against the slope.

When the outrigger is fixed to the vehicle body, the outrigger extends vertically on the slope to support the weight, and there is a risk that the outrigger may be damaged by a force in the bending direction. However, in the carrier vehicle 10 with a crane, when the pillars 23 of the crane 14 are raised in the vertical direction, the outriggers 15 support the crane 14 in the vertical direction, so that a force in the bending direction is not applied and the outrigger 15 is not easily damaged. The outrigger 15 serves to stabilize the turning of the crane 14, and also supports the crane-equipped carrier 10 during operation.
Make sure you brake.

When the crane 14 is used to load the timber on the material support member 13, it is necessary to move the felled timber from the logging location to the loading location. At this time,
The hydraulically driven winches 16 and 17 can be used to move the felled wood. First, as shown in FIG. 5, the rope 41 is hung on the hydraulically driven winch 16 and the roller 40, and the rope 4 is attached to the tension wheel 43 via the rollers 42, 42.
Multiply by 1. The roller 40 is installed at the place where the timber is felled. A pulley 44 is attached to the rope 41, and the rope 45 of the hydraulic drive winch 17 is hung on the pulley 44. A hook 46 is attached to the tip of the rope 45. The hydraulic drive winch 16 can be used by extending the hydraulic hose and separating it from the vehicle body 11.

When ready, hydraulically driven winch 1
6 is driven to move the pulley 44 to the location where the wood is cut near the roller 40. When the pulley 44 reaches the felling place, hook the string for bundling the wood on the hook 46,
The hydraulic drive winch 17 is driven to lift the timber. The lifted wood drives the hydraulic drive winch 16 to move to the loading place. When the loading place is reached, the hydraulic drive winch 17 is driven to lower the wood. By repeating this, the wood can be transported.

In the carrier 10 with a crane, the crane 14
Can be operated to grasp the timber at the loading place with the gathering clip 28 and load it on the transported object support member 13. Once a sufficient amount of wood has been loaded onto the load support member 13, remove the hydraulic drive winch 16 from the hydraulic coupler and
It is completely separated from the vehicle body 11. Further, the rope 45 of the hydraulically driven winch 17 is removed from the pulley 44. In this way, the carrier vehicle 10 with a crane can be moved without changing the hydraulically driven winch 16. As a result, the crane-equipped carrier 10 can be moved without the trouble of removing or hanging the rope 41 from the hydraulic drive winch 16, and the work efficiency can be improved.

When going down a slope, as shown in FIG.
The piston portion 32 of the hydraulic cylinder for tilting the crane is contracted, the crane 14 is rotated about the shaft 31, and the column 23 of the crane 14 is tilted toward the rear part of the vehicle body. The crane 14 is attached to the rear part of the vehicle body 11,
It is easy to move the center of gravity toward the rear of the vehicle when descending. When the felled timber is loaded and descended from the mountain, the weight of the timber loaded increases, but tilting the crane 14 toward the rear moves the center of gravity to the rear side of the vehicle body, which facilitates balance.

If the slope is fairly steep, the crane 14
Is tilted toward the rear of the vehicle, and the cabin 12 is slid toward the rear of the vehicle by a hydraulic cylinder. As a result, the center of gravity moves further toward the rear part of the vehicle body, and it becomes easier to stably descend the slope. However, when making a U-turn of the carrier 10 with a crane, or when it is necessary to expand the loading space for a load such as wood on the load support member 13, move the cabin 12 toward the front of the vehicle body. It is preferable to set.
