 Next, the operation of transporting the wall material will be described.

As shown in FIG. 10 (a), the support plate 45 is in a horizontal posture, and is moved forward and downward to contact the wall material A on which the support plates 45 are stacked, and the studs provided on the wall material A. The wall material A is fixed to the support plate 45 by inserting the bolt into the through hole 48 and tightening the nut.

At this time, since the wall material A is stacked sideways so that the longitudinal direction thereof is orthogonal to the traveling direction of the vehicle body, the wall material A is in a state of protruding leftward and rightward from the vehicle body 1.

As shown in FIG. 10 (b), the support plate 45 is slightly raised and the vehicle body 1 of the wall material A is swung 90 degrees by the turning motor 38.
On the other hand, the wall member A is held in a horizontal position by vertically adjusting the position so that the second frame 25 is reduced and the support plate 45 is slightly moved backward. Note that the wall plate A can be held in a substantially vertical posture by moving the support plate 45 upward and rotating it upward as indicated by the phantom line in FIG. 10 (b).

In the above-mentioned state, it moves forward and the wall material A faces the opening C of the building frame B as shown in FIG. 10 (c). At this time, the sensor 49
When the vehicle comes into contact with the lower part B ₁ of the opening of the building frame B, the vehicle body is automatically stopped. That is, the neutral position to demagnetize the first solenoid 53 ₁ of the first operating valve 51 ₁ in the signal of the sensor 49.

In this way, when traveling while holding the wall material A, the vehicle body stability is good and the weight of the wall material does not lean forward.

In other words, the vehicle body 1 has a substantially L-shaped front surface by the vehicle body 2 and the frame 3, the vehicle body 1 is supported by the main wheels 4 and 6 having a long axial distance, and the wall material A is pulled up onto the frame 3. Since the vehicle can be held in this state, the overturning moment acting on the vehicle body 1 is supported by the weights of the wheels 6 and the vehicle body 2, so that the vehicle body stability is good.

With the vehicle body stopped, the first frame 23 is raised, the second frame 25 is extended, and the support plate 45 is moved upward and forward, while the mounting plate 31 is rotated upward to rotate the support plate 45 upward. And the wall material A is in a vertical posture in a state of protruding outward from the opening C of the building body B.

After this, the second frame 25 is contracted and the support plate 45 is moved rearward to bring the wall material A into contact with the outer surface B ₂ of the building frame B, and the first frame 23 is moved upward, leftward and rightward to be supported. Board 45
Is moved up and down and left and right to position and hold the wall material A at a predetermined mounting position.

At this time, the front-rear center line of the vehicle body 1 is the outer surface B _{2 of the} building frame B.
Since the wall material A cannot be closely adhered unless it is orthogonal to, the left and right positioning bolts 47, 47 are tightened and the loosening operation is performed to swing the support plate 45 left and right as shown in FIG. By swinging to the left and right, the wall material A is brought into close contact with the outer surface B ₂ of the building frame B.

In this state, the wall material A is attached to the outer surface B ₂ of the building body A by some means, and after the attachment is completed, the nut is loosened to separate the wall material A and the support plate 45.

By repeating the above operation, the wall material A is attached to the outer surface B ₂ of the building frame B as an exterior material.

Further, when the wall material A is attached to the corner portion D as shown in FIG. 10 (e), the left and right positioning cylinders 50 are used for the first frame.
By moving 23 to the left and right and moving the support plate 45 to the left and right,
Since the wall material A can be moved left and right, it can be easily positioned and attached.

In the above embodiment, the wall material A is supported on the support plate 45 by inserting the stud bolt of the wall material A into the through hole 48 of the support plate 45 and tightening the nut. A mechanism may be provided so that the support plate 45 supports the wall material A.

 That is, the wall material support may be attached to the support plate 45.

In addition, by pushing the push button 84 of the first lever mechanism 61, the operation lever
The push button 84 of the second lever mechanism 62 is simultaneously swung 73 forward and backward.
When the operating lever 73 is swung back and forth by pressing, the vertical positioning cylinder 18 and the forward and backward positioning cylinder 28 simultaneously expand and contract to move the wall material A diagonally in the vertical direction, and its angle is arbitrarily selected by changing the operation stroke. it can.

Further, when the operation lever 73 of the first lever mechanism 61 is swung back and forth and at the same time the push button 84 of the second lever mechanism 62 is pushed to swing the operation lever 73 back and forth, the depression / elevation positioning cylinder 34
The front and rear positioning cylinder 28 simultaneously expands and contracts to move the wall material A back and forth while changing the depression and elevation angles.

Therefore, as shown in FIG. 10 (f), when the opening E of the building frame B is smaller than the wall material A, the wall material A is moved diagonally upward while the wall material A is inclined. Part E
When the wall material A can be moved further outward and similarly when the ceiling or floor has a raised portion, the wall material A can be moved forward while raising it to the side opposite to the raised portion. It suffices to simultaneously perform a forward / backward movement operation while looking at the ceiling or floor with a raised object, which simplifies the operation.

〔The invention's effect〕

Since the wall material supporter can move vertically and longitudinally with respect to the vehicle body 1 and swing up and down, the wall material supporter can vertically support the wall material on the floor and move it up and down and front and back. The wall material placed on the can be attached to the building frame.

In addition, by operating the operation lever 73 of the first lever mechanism 61 and the operation lever 73 of the second lever mechanism 62 back and forth, or by operating the back and forth while pressing the push button 84, the first operation valve and the third operation valve can be operated. Since the valve, the first operation valve and the second operation valve, and the second operation valve and the third operation valve can be switched to the first and second pressure oil supply positions at the same time, the vertical positioning cylinder 18 and the depression / elevation positioning cylinder 34, the vertical positioning cylinder 18 and the front-back positioning cylinder 28, the front-back positioning cylinder 28, and the depression / elevation positioning cylinder 34 can be operated simultaneously.

Therefore, the wall material support can be moved diagonally upward or can be moved forward while swinging up and down, and the wall material can be moved outward from the opening smaller than the wall material, or can be moved while avoiding the raised portion. It can be done with a simple operation.

In addition, the flow rate supplied to the vertical positioning cylinder 18, the front-back positioning cylinder 28, and the elevation-angle positioning cylinder 34 can be controlled by the amount of electricity supplied to the proportional solenoids of the first, second, and third flow rate control valves. Each can be controlled independently, and the amount of electricity to the proportional solenoid is controlled by the operating lever.
Since it is controlled by the operation amount of 73, the operation speed when operating each cylinder independently can be controlled arbitrarily by the operation amount of the operation lever 73, and even when operating multiple cylinders simultaneously, each operation speed can be set arbitrarily. Can be controlled.

Therefore, the angle at which the wall member support is moved diagonally upward can be set arbitrarily, and the vertical swing amount and the forward movement amount can be set arbitrarily.
