DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables easy loading and unloading of concrete blocks, and moreover, grasps concrete blocks which can be used by attaching them to a forklift, a loader or a crane. It concerns the device.

[0002]

2. Description of the Related Art Conventionally, there has been a machine that sucks and moves a concrete block by negative pressure (vacuum). However, since the blocks cannot be loaded because the interval between the blocks is too large, the loading operation has been performed manually.

[0003]

The concrete block product can be gripped and loaded so that it does not collapse in a manufacturing factory or the like, and can be staggered to save space. It is an object of the present invention to provide a concrete block gripping device capable of carrying out cargo handling without any trouble.

[0004]

Means for Solving the Problems A frame body 1 comprising an upper frame 1a and a lower frame 1b which are vertically framed in parallel with a gap 3 above and below, and a pressing plate 4 which can be moved laterally and has a rubber plate at the lower end. A presser plate supporting device 6 which can expand and contract vertically, a presser plate lateral moving device 10 mounted between adjacent presser plate support devices 6, and a hydraulic cylinder 12 for driving the presser plate lateral moving device. The plate supporting device 6 includes a pair of outer tubes 6a having an upper end connected by an upper shaft 8 located between the upper frame 1a and the lower frame 1b, and a pair of movable rods 6b having a lower end connected by a lower shaft 7. The presser plate lateral moving device 10 is configured to be extendable and contractable, the intermediate portion is pivotally supported by an intermediate shaft 11, the upper end of which is connected to the upper shaft 8 of one of the adjacent support devices 6, and the lower end of which is the other. It comprises cross arms 10a and 10b pivotally supported on the lower shaft 7 of the support device 6, respectively. Bearing rings 9 are mounted on both sides of the upper shaft 8 to facilitate lateral movement. Further, the upper shaft 8 of the holding plate supporting device 6 at the center position is fixed between the upper frame 1a and the lower frame 1b so that the supporting devices on both sides are centered. Further, a turntable 14 is provided at the upper center of the upper frame 1a, and a table is formed on the turntable.
The claw mounting frame 15 is fixed so that it can be loaded and unloaded by a forklift.

[0005]

When the hydraulic cylinder 12 is actuated, the holding plates 4 on both sides are pushed toward the center. Then, all the holding plates 4 are pushed and moved toward the center via the holding plate lateral moving device 10. By this movement, a plurality of blocks a can be firmly held, and a plurality of blocks a... Can be simultaneously transported by a forklift or the like.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. As apparent from the drawing, the present invention is a gripping device capable of simultaneously lifting a plurality (six in the drawing) of concrete blocks (hereinafter simply referred to as blocks) a. In FIG. 1, reference numeral 1 denotes a frame, which comprises an upper frame 1a and a lower frame 1b. The upper frame 1a and the lower frame 1b are vertically separated from each other by d, and a gap 3 is provided. Numeral 4 denotes a block holding plate on which rubber plates 5 for preventing slipping are mounted on both sides. However, the block holding plates 4 on both sides are rubber plates 5 only on one side.
And the length thereof is longer than that of the block holding plate 4 in the middle.

[0007] The block holding plate 4 is supported by a holding plate support device 6. The holding plate supporting device 6 includes an upper frame 1a and a lower frame 1b.
A pair of outer tubes 6a connected by an upper shaft 8 located therebetween and a pair of movable rods 6b connected by a lower shaft 7 are configured to be vertically expandable and contractible. The holding plate supporting device 6 is a holding plate lateral moving device 1.
At 0, it can move toward the center. Presser plate horizontal moving device 1
Reference numeral 0 denotes an intermediate shaft that is pivotally supported at an intermediate portion.
The crossarms 10a and 10b are pivoted respectively. Numeral 12 denotes a hydraulic cylinder whose rod end is pivotally supported by an outermost block pressing plate 4a with a pin 12a, and whose cylinder side is pivotally supported by the lower end of the lower frame 1b with a pin 12b. Reference numeral 13 denotes a support block fixed at the center of the gap 3 between the upper frame 1a and the lower frame 1b.
Are fixedly supported. Therefore, the supporting device 6 at this center portion
Is fixed in this position. 14 is a turntable with an upper frame
It is attached to the upper center of 1a via an attachment bracket 17. A fork claw mounting frame 15 is mounted on the top of the turntable 14. Reference numeral 16 denotes a fork claw pushing member.

[0008]

[Operation]

(1) As shown in FIG. 1, a plurality of manufactured blocks a
Where each of the block holding plates 4 of the gripping device A is located.
... with the fork claw descended. (2) Supply pressure oil to the hydraulic cylinders 12 at both ends and press the block holding plates 4 at both ends from the side. (3) The pressing force acts inward through the cross arms 10a and 10b of the holding plate lateral moving device 10, and the supporting device 6 moves toward the center. At this time, the support device 6 in the middle part extends downward. During the movement, the upper bearing wheel 9 is smoothly guided by being guided between the upper frame 1a and the lower frame 1b. (4) When the supply of the pressure oil is closed when both side surfaces of the block a are completely pressed by the block holding plates 4 and 4, the plurality of blocks a and the gripping device A are integrated. (5) Raise the fork claw, move it to another moving place, and unload by reverse operation.

[0009]

A plurality of block holding plates 4 movable toward the center of the gripping device A are provided, and these can be moved simultaneously via the holding plate lateral moving device by driving the hydraulic cylinder. Can be grasped and transported at the same time, making extremely safe and efficient work possible. Since the plurality of blocks a are gripped at a constant interval, staggered stacking is also possible, and the orderly transport / loading operation can be performed efficiently without requiring any manual operation.
