Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for stacking stone materials when constructing a stone wall or the like, and is particularly effective at a construction site where the crane cannot be freely operated.

[0002]

2. Description of the Related Art Up to now, in the above-mentioned field, in the case of heavy stones of a standard size such as Otani stone, two workers lift the stones one by one to reach a predetermined position, in addition to the stones of a particularly small volume. Must be stacked. Needless to say, the work is heavy labor and the workability is extremely low.

[0003]

SUMMARY OF THE INVENTION In view of the above, the present invention eliminates the manual operation of the clamp when the stone is carried to a predetermined place by a crane or the like, and the stone can be moved to a predetermined position by a simple operation by one person. The present invention provides a device that can be moved and stacked up to the other side, and more specifically, a combination device of a clamp, a carriage, and a corner guide plate.

[0004]

In order to achieve the above object, the present invention comprises a clamp 1, a movable pulling carriage 6 and a corner guide plate 16 as shown in FIGS . The clamp 1 has a direction guide rod 3 protruding from the lower part of one arm 2 and an automatic locking device 5 at the arm intersection 4.
At least the front wheels of the movable pull-out carriage 6 are caster 7
The front and rear sides are provided with flip-up guide wheels 8, the front end upper part is provided with a feeding roller 9 and the rear end part is provided with a floating roller 10 which can be retracted, and the lower part of the rear end edge is provided with a pressing brake 12. To provide. The corner guide plate 16 is formed by forming the inside of the substantially right-angled intersecting plate 14 into a round shape and bending the inscribed support plate 15 vertically downward from the inner edge 14a thereof. It is a stone material moving and stacking device characterized in that.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Now, referring to the embodiments of the drawings, FIG.
In FIG. 4 , 1 is a clamp, and one arm 2 thereof
Two direction guide rods 3 are provided on the lower part so as to project. This direction guide rod 3 seems to be simple, and when hoisting a stone material with a clamp, it plays an important function of correcting the direction when the holding part 2a of the clamp arm 2 is misaligned with the sandwiching side surface of the stone material. Further, the arm intersection 4 is provided with an automatic lock device 5. This automatic locking device automatically opens and closes by utilizing the heavy pressure when the clamp 1 descends toward a stone material. Specifically, one arm 2 is provided with a fitting insertion portion 5a in the longitudinal direction. , The guide pin 5 in which the propelling screw shaft 5c is fitted and inserted in the fitting and inserting portion 5a and is inserted from the outside horizontal direction of the fitting and inserting portion 5a.
It is possible to move up and down along b, and further the propulsion screw shaft 5c
A lock bar 5d that straddles the intersection 4 of the arms 2 and 2 is fixed to the head end of the arm 2, and the tip of the lock bar 5d and the upper portion of the one arm 2 are connected by a spring 5e to always The lock bar 5d is configured to be maintained in a state of straddling the intersection 4.

Next, in FIG. 3 , reference numeral 6 denotes a movable pulling trolley, which has casters 7 as front wheels and rollers 11 as rear wheels, and is provided with horizontally oriented guide wheels 8 on both front and rear sides which can be flipped upward when unnecessary. A stone drop chute 13 is provided in the front part. Further, a feeding roller 9 is provided above the front edge, a floating roller 10 that can be retracted above the rear edge, and a pressure brake 12 is provided below the rear edge. This pressure brake 12
Although various modes are conceivable, in the same drawing, a brake rod 12b is vertically inserted along a guide frame 12a via a return spring 12d, and a brake shoe 12e is attached to a lower end of the brake rod 12b. Is shown.

Finally, the corner guide plate 16 forms an inner side of the substantially right-angled crossing plate 14 into an arc shape, and the inner edge 14 thereof.
The inscribed support plate 15 is formed to bend vertically downward from a. The stone moving and stacking device of the present invention is composed of the above three elements.

[0008]

Now, the case of stacking stones by the device of the present invention will be described. First, in FIG. 5 and FIG. 6 , the process of placing the stones S on the movable pulling carriage 6 at a predetermined position by the clamp 1 will be described. ) Lowers the clamp 1 in a locked state, which is hung on a crane, toward the stone material S, and the angle is corrected by the direction guide rod 3 so that the holding portion 2a of the clamp arm 2 is in contact with the sandwiching side surface of the stone material. B)
Further lowers the clamp 1 to abut the propelling screw shaft 5c of the automatic locking device 5 against the upper surface of the stone material S and to move it upward while rotating it along the guide pin 5b due to its heavy pressure, so that the intersection of the arms 2 and 2 is crossed. The state where the lock bar 5d straddling 4 is laterally removed (unlocked), and (c) lifts the clamp 1 to lift the stone S from that state (at this time, the propulsion screw shaft 5c is the upper surface of the stone S). The force of the spring 5e tries to return it to the original position due to the action of the spring 5e, but the surface of the arm 2 interferes with it and stores its restoring force), and (d) moves the clamp 1 to move the pull-out cart 6 at a predetermined position. When the clamp 1 is further pushed down and the clamp 1 is further pushed down, the arms 2 and 2 which are still in the unlocked state open and the lock bar 5d is straddled over the intersection 4 again by the restoring force of the spring 5e. To maintain the state. Due to the operation so far, it is not necessary for the operator to manually open and close the clamp 1.

Next, as shown in FIG. 7 , the movable pull-out carriage 6 on which the stone S is placed is moved to the stacking position. At this time, the carriage 6 is transported in a smooth and stable state while being guided by the front, rear, left and right guide wheels 8. Then, when the worker approaches the stacking point, specifically, a little closer to the length of the stone material S, the worker simultaneously pushes up the floating roller 9 and pushes down the pressure brake 12 with the bar B held by the worker. , Push the stone S forward by hand. The stone material S slides down without difficulty, leaving the dolly 6 on which the brake is applied due to the rolling action of the front feeding roller 9 and the rear levitation roller 9, so that the rear end portion of the stone S still hangs on the dolly 6 as shown in FIG. 8 is released, the push-down operation of the pressure brake 12 is released, and FIG.
Next, pull out the dolly 6 to the front as shown in FIG. Then, the carriage 6 is returned to the predetermined position again, and the same work is repeated thereafter.

[0010] To perform the right-angled intersection of movement of the carriage 6, on which passes a corner guide plate 16 (shown in FIG. 4) in the corner portion as shown in FIG. 9, when moving the carriage 6, the front wheel Coupled with the casters 7, the curve can be cut in a stable state. At this time, the front and rear guide wheels 8 on the outside of the carriage 6 interfere with each other and therefore are to be flipped up.

[0011]

As described above, according to the device of the present invention, the opening / closing operation of the clamp for suspending the stone material can be automatically performed, and the stone material is placed on the trolley set at a predetermined position, and then With regard to the dolly, the stacking is completed by a very simple operation of moving the position, simultaneously pushing up the floating roller and pushing down the pressure brake, pushing the stone forward and pulling out the dolly. In the corner as well, the trolley can be moved without any trouble by using the corner guide plate, and as a whole, one worker can perform extremely labor-saving and efficient work, and especially the crane can be freely operated. It is effective in a narrow construction site where it is difficult to drive.
