Abstract

PURPOSE:To improve visional field of a working vehicle by a method in which a cabin with a front glass whose both ends are curved is provided on the side of a slewing base having a boom pivotally supported on its central front end in a horizontally rocking manner, and the oil-pressure pipe of the boom is connected with the oil-pressure pipe of the slewing base. CONSTITUTION:A boom 11 is attached to the center of the front end of an upper slewing body 3 in a horizontally rocking manner, and a cabin (operating room) 7 is attached eccentrically on the left side of the upper part of the upper slewing base 3. The cabin 7 has a front glass 8 whose left and right ends are provided with a curved face cut into the side wall side. An oil-pressure hose pipe 10 is set close to the right-handed cut-in portion of the front glass 8, and the steel pipe 13 of the boom 11 is connected nearly straightforwardly. The structure of the oil-pressure pipe can thus be simplified and visibility of operation can also be enhanced.

BACKGROUND ART FIGS. 1 and 2 show the conventional structure of this type of work vehicle, in which a lower running vehicle body (1) equipped with a crawler (1) is shown.
2) An upper swing body (3) is mounted on top as a 360 degree swing point. A boom (11) of an excavator (12) is pivotally attached to the center of the front end of the upper swing vehicle body (3) so as to be able to swing left and right by a swing cylinder (4). (5) shows an arm attached to the tip of this boom, and (6) shows a packet also attached to the tip of arm (5). This upper rotating vehicle body (2)
A box-shaped cabin (7) is placed at the top of the front end of the excavator (12). The operation can be visually confirmed. Furthermore,
On the upper surface of the upper rotating vehicle body (2), there is a hydraulic hose pipe (10) adjacent to the side wall surface on the opposite side to the eccentric direction of the cabin (71).
The hydraulic hose pipe (10) is bent into an Ω-shape or an n-shape and raised upward, as in FIG. ) is connected to the hydraulic steel pipe piping (13) on the excavator (12) side.

Problems to be Solved by the Invention Now, in the above conventional structure, the boom (11) is
It is attached to the center of the front end of the upper swinging vehicle body (3), and when this boom (11) is turned all the way to the right, it is pressed strongly against the glass (9) on the side wall of the cabin (7), causing the hydraulic pressure to There is a risk that the hose piping (10) will be damaged.
Therefore, this hydraulic hose piping (10) must be installed quite eccentrically to the right side from the center, and in this case, the hydraulic steel pipe piping (13) connected to this hydraulic hose piping (10) cannot be connected as it is. I can't do it,
As shown in FIG. 2, it is necessary to make a connection by bending it significantly to the right, and as a result, the hydraulic piping is complicated and the cost is high. In addition, as another structure of the hydraulic piping, in order to prevent the hydraulic hose piping (10) from coming into contact with the cabin (7), it is placed on the right side and a guide plate is installed to prevent the hydraulic hose piping (10) from rising. It is necessary to add a seat, which increases the cost.On the other hand, there are some models in which the entire cabin (7) is lowered to the rear.
Doing so has the disadvantage that the visibility of the front part of the cabin (7) is sacrificed. In addition, in such a box-shaped cabin structure, the front glass (8) and side glass (
9) are arranged at right angles by the frame (14), so when the boom (3) is fully swung to the left or right, the frame (14) (14) gets in the way and makes it difficult to work properly. cannot be seen, impairing safety,
Moreover, since the operator has to tilt his or her head to view the image, there is a drawback that this increases fatigue.

The present invention has been developed in view of these conventional drawbacks, and does not require complicating hydraulic piping or lowering the entire cabin to the rear, and also improves the forward visibility during work. The aim is to provide good working vehicles.

Embodiment Below, the structure of the present invention will be explained based on an illustrated embodiment. FIG. 3 shows the first embodiment of the present invention. ) The cabin (7) is mounted eccentrically to the left in the upper part of the cabin (7), and its front glass (8) has a bent shape with both left and right ends formed into curved surfaces cut into the side walls. By forming both ends of the front glass (8) into a bent shape in this way, there is a margin at the right corner of the front end of the cabin (7). ) is placed closer to the notch in the front glass (8) and closer to the center, and accordingly, the hydraulic steel pipe (13) is not bent as shown in Figure 2.
It is connected to this hydraulic hose pipe (1o) in a substantially straight line. Therefore, in this embodiment, the hydraulic hose piping (10) is placed closer to the center by the bending of the front glass (8), which simplifies the structure of the hydraulic piping.
In addition, since the frame (14) is located at the rear, even when the boom (11) is turned all the way to the left and right, it is not obstructed by the frame (14), making it easy to see the work status. It is.

FIG. 5 shows a third embodiment of the present invention, which is applied to a relatively large work vehicle. In order to improve the forward visibility, the cabin +71 is protruded from the front end of the upper revolving vehicle body (3). , and the boom (11) of the excavator is pivotally attached to the front end of the upper swing vehicle body (3). In the work vehicle of this embodiment, a boom (
11), there is a risk of it touching the cabin (7) when the boom (11) is turned to the left. Therefore, the swing fulcrum of the boom (11) is However, if this is done, the boom (11) will move away from the center of gravity of the vehicle, worsening the front and rear stability, and the boom (11)
Due to its relationship with the cabin (7), it had to be installed eccentrically to the right of the center of the car body, which had the disadvantage of poor car body stability. In this embodiment, as in the first and second embodiments, both ends of the front glass (8) of the cabin (7) have a curved shape cut into the side wall surface, so that the boom (11) can be turned all the way to the left. The turning angle when the vehicle is turned can be expanded to 40 degrees to 55 degrees compared to conventional models, without compromising longitudinal stability (and improving forward visibility).

FIG. 6 shows the same work vehicle as in FIG. 5, with the front glass (8) having a curved shape as in FIG. 5, and with this,
Lower the fulcrum P of the boom (11) to the rear and lower the upper rotating vehicle body (
3) is located closer to the center of gravity, which improves the stability of the vehicle body and shortens the overall length, resulting in a smaller turning radius when traveling and improved workability.

In both of FIGS. 5 and 6, both ends of the front glass (8) may be sloped as shown in FIG. 4.

Effects of the Invention The present invention has the above configuration, and according to the present invention, both ends of the front glass of the cabin (both sides have a bent shape where one side is cut into the side wall surface side), so this bent shape portion is By placing it on the excavator's piping side, the hydraulic hose piping connected to the excavator side can be installed closer to the center of the vehicle body, making it possible to bend the steel pipe piping on the boom side attached to the center of the vehicle body. Alternatively, there is no need to hold it down with a guide plate, the hydraulic piping structure is simple, it can be constructed at low cost, and it is possible to obtain a work vehicle with good forward visibility and good visibility. Furthermore, in the present invention, by forming the windshield into a bent shape in this way, in a vehicle where the boom is disposed on the side of the cabin, the swing angle of the boom can be widened, which increases work efficiency. Alternatively, the swing fulcrum of the boom can be placed closer to the center of the vehicle body and closer to the center of gravity of the vehicle, resulting in a work vehicle with good stability and safety.
