[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long material installation device for standing up and installing a long material lying down.

[0002]

2. Description of the Related Art For example, in the construction of an underground structure,
After providing underground equipment in the underground space, a long and heavy precast wall (preformed wall) may be built as a part of the wall surrounding the underground equipment. Part of the wall is used as a precast wall because it is necessary to remove the precast wall when inspecting and replacing the underground facility.

This precast wall has been built in the past.
It is carried out by using a small winch and a gold wheel (pulley).

[0004]

However, in such a building method, the suspended precast wall (preformed wall) may sway in a narrow working space where there are already underground facilities in the underground space. Therefore, its movement and installation work are complicated.

In such a narrow working space, it is difficult to carry out the work using a large forklift truck or the like.

In view of the above circumstances, it is an object of the present invention to provide a long material installation device capable of easily and quickly performing the work of erecting and installing long materials even in a narrow work space.

[0007]

According to a first aspect of the present invention, in a long material installation device for standing up and installing a long material lying down, a traveling device and a hoisting drive are provided on the traveling device. A gripping arm that is raised by gripping a long lying material, raises the long material and lifts it, and a support leg that is provided around the traveling device so that it can be grounded and released from the ground and supports the traveling device. , A leg projecting / retracting mechanism for projecting and retracting the support leg in a horizontal direction parallel to the undulating drive surface of the gripping arm.

That is, when standing up and lifting a long lying material, first, the supporting leg is projected by the leg projecting / retracting mechanism in the horizontal direction parallel to the undulating drive surface of the gripping arm, and is supported. Ground your legs. Therefore, the gripping arm is laid down, and the long material lying down on the gripping arm is gripped, the gripping arm is raised, and at the same time, the long material is raised and lifted. At this time, the center of gravity of the device and the large-sized material is remarkably moved toward the support leg, but the support leg supports the center of gravity so that the fall is prevented.

Further, after the gripping arm is raised, the center of gravity of the device and the long material is returned to the center of gravity of the traveling device.
Move backward to the traveling device side. Then, the long-sized material installation device has a small size and can travel even in a narrow work space.

Further, since the gripping arm grips a long material, it sways less than when it is hung. Therefore, it is easy to move and install long materials.

A second invention of the present invention is characterized in that, in the long material installation device of the first invention, the support leg has a wheel at its lower end. That is, when the support leg is projected and retracted, the two wheels are grounded, so that the support leg is easily and movably supported, so that the projection and retraction are smoothly performed. Further, since the wheel supports the protruding / retracting frame of the leg protruding / retracting mechanism, the protruding / retracting frame can be lengthened, and the supporting leg can be projected further away.

Further, the angle of the precast wall 1 in the front-rear direction can be adjusted by a grip portion elevation hydraulic cylinder 29 that rotates the grip portion 23 in the directions of arrows I and J in the figure, as shown in FIG. , The grip body 2 of the grip arm 20
The left-right adjustment mechanism 25 for positioning and adjusting 4 in the left-right direction (arrow K and L directions in the drawing) can adjust the position of the precast wall 1 in the left-right direction. Further, the swing motor 26 that swings the grip body 24 about the central axis CT1 thereof can adjust the angle of the precast wall 1 in the left-right direction.

Therefore, the precast wall 1 can be easily and quickly installed at a predetermined installation place.

Further, the detachment of the grip portion 23 after the precast wall 1 is installed can be easily and quickly performed by detaching and driving a pin (not shown) of the grip portion 23.

Therefore, in the long-sized material installation device 100, even in a narrow work space S, the work for erecting, moving and installing the precast wall 1 can be performed easily and quickly.

Further, if the hydraulic unit 70 and the wheels 12, 12, 12, 12 of the long material installation device 100 of FIG. 3 are driven by electric power, noise can be reduced and the air can be cleaned. Can be kept at

In the above embodiment, the wheels 12, 12, 12, 12 of the traveling device 10 are manually steered by the steering wheel 19, but instead of the steering wheel 19, the four-wheel steering shown in FIG.
