The bending arm 10 is provided with the rotation support shaft 12b on the center line 30, and can be arranged at the front position A of the driver's seat and the front position B of the work operation console, which are also on the center line 30. , Are aligned on the center line 30 at any position. On the other hand, all the fixed accessories are provided on the right side in the forward direction of the traveling vehicle body 1 with respect to the center line 30, and are provided at a distance from the bending arm 10 aligned with the center line 30. . Further, on the left side of the center line 30, there is no fixed accessory that hinders the pivotal movement of the bending arm 10. That is, the fixed accessory protruding above the traveling vehicle body 1 is disposed on one side of the fixed center line of the transfer means, and is provided outside the substantially semicircular movement range in which the transfer means is rotated and fixed. It is what has been.

Next, the detailed structure of the control means fixing portion 21 will be described. As shown in FIGS. 3 and 4, a mounting bracket 9f is provided obliquely below the control means 9.
Is covered with a bracket opening 9g having a square cross section, and the bottom of the mounting bracket 9f located above the bracket opening 9g rotates between the spacer 20d pressed by the bolt 28 and the outer ring of the bearing 27. It is supposed to do. Further, setscrews 22 are respectively screwed into the two side surfaces 9h and 9i of the bracket opening 9g which are orthogonal to each other, and the rotary pedestal 20c fixed to the upper portion of the cylinder portion 20b is pressed and fixed. Therefore, it is possible to loosen the set screw 22 and rotate the control means 9 via the bearing 27.

Next, the detailed structure of the control means 9 will be described. The control means 9 provided at the tip of the mounting bracket 9f is provided with an operation handle 9a for operating the traveling direction of the traveling vehicle body 1 and an operation lever 9e on a control panel 9b on the upper surface of a substantially rectangular parallelepiped control box 9c. , Instruct other running and paving work

As described above, the mounting bracket 9f is provided on the lower surface of the control box 9c, and is fixed to the tip of the standing arm portion 20 so as to be rotatable about its central axis. The mounting bracket 9f
However, the reason why the control panel 9b is inclined from the lower surface is that the control panel 9b is also inclined with respect to the horizontal plane so that the operator 11 can easily see and operate the control panel 9b.

Next, detailed configurations of the arm fixing portion and the arm fixing mechanism according to the present invention will be described. Arm fixing part 7
Are provided on the driver's seat 3 for fixing the control means 9 to the front position A of the driver's seat, and those of the driver's seat 3 for fixing the control means 9 to the front position B of the work operation console. Some extend from below the rear side. The arm fixing mechanism is provided on the bending arm 10.

Therefore, first, referring to FIG. 5, the arm fixing mechanism and the control means 9 are installed at the front position A of the driver's seat.
The structure of the arm fixing part for fixing to the arm will be described.

As shown in FIG. 5A, the arm 20a
The lever clamper 23 (arm fixing mechanism) provided on the end portion of the bracket 19 fixed on the side surface of the movable side driver pedestal arm fixing portion 24 and the fixed side driver pedestal arm projected upward from the driver pedestal 3. Fixing metal fitting 2 in which the tip of the fixing portion 29 is bent downward to form a hook
Clamp fittings 23a that engage with 4a and 29a, respectively
Is hooked up and pulled up. As a result, the bending arm 10 includes the movable driver's pedestal arm fixing portion 2
4 and the fixed side pedestal arm fixing portion 29, and is fixed in the vertical direction and the rotating direction of the bending arm 10.

Therefore, one end of the lever clamper 23 is fixed to the bracket 19 and is pin-locked to the laterally projecting pin locking portion 19a, and the other end is processed so as to be easily gripped by a hand. A lever 23c provided with a pin locking portion 23e between the two parts, an arm 23b having one end extended to the pin locking portion 23e by pin locking, and the other end of the arm 23b, for example, a coil spring and a guide rod (not shown). ) Or the like to provide elastic force to support the clamp metal fitting 23a which is movable in the longitudinal direction.

The movable side pedestal arm fixing portion 24
Is a fixed plate 24c fixed to the driver's seat 3 and a fixed plate 24b fixed to the fixing metal fitting 24a, which are hinged together by a hinge 24d.
It is configured to be able to stand upright at a right angle from the driver's seat 3 and come into contact with the side surface of the arm 20a, and to fall and retract toward the driver's seat 3 when the arm 20a rotates.

Next, the work operation console arm fixing portion 26 for moving and fixing the control means 9 to the front position B of the work operation console is shown in FIG. A support bracket 26b extending horizontally,
An inclination receiving portion 26c is provided at the tip of the arm 20 so as to be inclined rearward, and the arm 20 is erected vertically to the inclined surface.
The side surface receiving portion 26d is provided with a space for holding a and sandwiched from the side surface, and the hook portion is formed on the outer side surface of the side surface receiving portion 26d by bending the tip into a mountain shape to form a hook shape. A fixing metal fitting 26a which is vertically fixed to the inclined surface and fixed. FIG. 2B shows a C-C cross section showing the relationship between them.

Next, the operation of moving the control means 9 from the front position A of the driver's seat to the front position B of the work operation console in the apparatus according to the present invention described above will be described. FIG. 7 is an explanatory view showing a state in which the control means 9 is moved to the front position B of the work operation console. The schematic operation up to this state is shown in FIGS. 8 (a) and 8 (b).

First, the setscrews 22 (two places) that fix the control means 9 to the standing arm portion 20 are loosened, the position of the control means 9 is reversed 180 degrees in the horizontal plane, and then fixed at that position. .

Next, in order to rotate the bending arm 10 in the horizontal direction, the fixing of the movable side pedestal arm fixing portion 24 and the fixed side driving pedestal arm fixing portion 29 to the driving pedestal 3 is released. In this operation, as shown in FIG. 5B, each lever 23c of the lever clamper 23 is moved to the arm 2
0a to the outside of the side surface to lower the pin locking portion 23e and the arm 23b locked therein,
This is performed by releasing the engagement between the clamp metal fitting 23a at the tip and the fixing metal fittings 24a and 29a by moving the clamp metal fitting 23a on the outer side of 0a.

After releasing the above, the fixing plate 24b is tilted in the direction of rotation of the hinge 24d so that the movable side driving pedestal arm fixing portion 24 does not hinder the rotation of the bending arm 10 on the driving pedestal 3. Fold. (Fig. 5 (b))

From this state, the bending arm 10 on which the control means 9 is mounted is horizontally rotated about the rotation support shaft 12b, and the horizontal arm portion 12 of the bending arm 10 is rotated.
Is moved to a position rotated 180 degrees with respect to the original position,
The control means 9 is located just behind the driver's seat 6 (FIG. 8 (a)). At this time, since the seat fixing column 14 supporting the driver's seat 6 is out of the rotation range of the horizontal arm portion 12, it does not hinder the rotation, and FIGS.
As shown in (b), since the height of the horizontal arm portion 12 is lower than that of the seat 6a, the seat 6a does not hinder the rotation.
Further, since the control means 9 is supported by the bending arm 10 that is bent in a substantially L shape, it has a positional relationship that does not interfere with any part of the driver's seat 6. Further, while this rotation is performed, the bracket 19 is held in the posture in which it is housed on the inner surface of the arm 12a by the elastic force of the coil spring 15 fixed to the arm 12a and extends in the horizontal direction.

Next, when the control means 9 is pushed downward from the rear side, the coil spring 15 is stretched and the bracket 19 is pivoted about the pin 18 to be in the middle bent state. Then, the side surface receiving portion 26d protruding upward on the work operation table arm fixing portion 26 guides the side surface to lower the bottom surface of the bracket 19 to a position where it can be received by the inclined receiving portion 26c (FIG. 8B). This turning operation requires a certain amount of force to resist the coil spring 15 in the initial stage, but as the turning operation increases, the bending moment due to the weight of the control means 9 increases and the turning force is gradually reduced. In the state of abutting on the side surface receiving portion 26d, the elastic force of the coil spring 15 has a force relationship such that the rotation does not return to the original state.

In this state, the clamp metal fittings 23 of the lever clamper 23 provided on both sides of the bracket 19 are provided.
The bending arm 10 is fixed to the work operation base arm fixing portion 26 by engaging a with the fixing metal fittings 26a (two places). Then, the control means 9 is moved to the front position B of the work operation console and fixed (FIG. 7).

If the above operation is performed in the reverse order, the control means 9 can be moved from the front position B of the work operation console to the front position A of the driver's seat. Therefore, the control means 9 can be moved by the transfer means according to the present invention. It is possible to reciprocate between the front position A of the driver's seat and the front position B of the work operation console.

According to the above relocation means, the driver's seat 6
Since the control means 9 can be relocated without moving at all while fixing the car, there is no need to remove or tilt the driver's seat 6 to evacuate during the relocation, and an extra space or mechanism is placed on the driver's pedestal 3. There is an advantage that it is not necessary to provide. Therefore, the workability of relocation is improved. Also, if necessary, the worker 11 can sit in the driver's seat 6 during or after the relocation.

Further, fixed accessories collected at a distance from the central shaft 30 on one side (right side in the above) of the central shaft 30 which is the fixed central shaft of the moving device are also outside the rotation range of the moving device. Therefore, it is not necessary to move or evacuate, and the workability of relocation can be improved.

Further, in the above-mentioned relocation, since the control means 9 on the front of the driver's seat 6 is rotated 180 degrees and moved to the back, the position of the worker 11 with respect to the traveling direction of the traveling vehicle body 1 is changed at any time. Since it is unnecessary, the sense of distance between the left and right of the worker 11 is kept the same at any position, so that there is an advantage that stable traveling operation can be performed even if the worker is relocated.

Further, since the bending arm 10 can be bent and rotated downward by the pin 18, it is preferable even when the position of the work operation table 4c is relatively far from the driver's seat 6 and relatively low. It is possible to relocate in a posture.

In the above description, the bending arm 10 is described as the L-shaped one in which the standing arm portion 20 extends vertically upward from the horizontal arm portion 12, but the bending shape is as follows.
Needless to say, it is not limited to the L-shape as long as it can avoid the driver's seat 6 during turning. For example, it may have an inverted V shape, or each arm may be bent.

Further, in the above description, the bending arm 1 is provided by fixing the work operation base arm fixing portion 26.
The example in which the bending angle of 0 is limited to one has been described. The operation console arm fixing portion 26 may be provided so that the posture can be changed. In that case, since the position in the height direction can be changed according to the height of the worker 11 or the like,
There is an advantage that operability is improved.

In the above description, the bending arm 10 is bent in the middle, and the control means 9 is arranged obliquely downward. However, depending on the overall layout of the traveling vehicle body 1, the bending arm 10 is rotated 180 degrees. In this state, the worker 11 standing on the work operation table 4c may be in a convenient position for operation. In such a case, it goes without saying that the bending operation and the mechanism therefor are unnecessary.

In the above description, an example in which the bending arm 10 is accurately rotated by 180 degrees has been described, but of course, even if the bending arm 10 is deviated from 180 degrees within a range of several degrees,
Needless to say, it is easy to change the shape of the work operation table arm fixing portion 26 to deal with it, and even in that case, substantially the same effect as described above can be obtained.

In the above description, as an example in which fixing and releasing can be performed relatively easily, the case where the arm fixing portion is constituted by the engagement of the lever clamper 23 and the fixing metal fittings 24a, 26a, 29a has been explained. , Bending arm 10
It goes without saying that the mechanism is not limited to such a mechanism as long as it can be fixed. For example, it may be fixed by inserting a pin, fixed by hanging a lever in the shape of a bolt, or fixed by screwing in a bolt.

[0053]

As described above, according to the first aspect of the invention, the control means can be moved between the front of the driver's seat and the front of the work operation console located on the rear of the driver's seat with the driver's seat fixed. As a result, the operability can be improved.

In the invention described in claim 2, in addition to the above, the center folding mechanism can provide a degree of freedom in the arrangement position of the control means, and the pulling force of the spring prevents the control means from being lowered by its own weight. Therefore, it is possible to arrange the control means at a position where the operability is improved.

According to the third aspect of the invention, in addition to the above, the control means can be moved substantially right behind the driver's seat, so that the left and right distance feeling can be kept substantially the same for the driver who is driving. As a result, the operability of traveling can be improved.
