[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet for transporting construction materials, such as concrete secondary products such as masonry blocks, to a predetermined position on a construction site.

[0002]

2. Description of the Related Art Conventionally, in order to transport a concrete secondary product such as a masonry block to a predetermined position on a construction site, as shown in FIG. 7, or as shown in FIG. 7, a concrete secondary product is suspended and carried on a truck crane via a wire rope.

[0003] However, the loading into the bucket or the hanging from a wire rope can carry only one or a few concrete secondary products, which is not only low in work efficiency but also caused by the manual operation of blocks and the like. Loading and unloading operations are dangerous, and there are problems such as harsh operations.

[0004]

[Problems to be solved by the invention] The present invention has been made to solve the above-mentioned conventional problems. The purpose of the invention is to release workers from troublesome work, and to provide concrete secondary products and the like. An object of the present invention is to provide a pallet for transporting construction materials that can transport construction materials safely and efficiently.

[0005]

SUMMARY OF THE INVENTION A pallet for transporting construction materials according to the present invention has a mounting plate on which a concrete secondary product such as a masonry block is mounted, and the mounting plate is detachably fixed to a blade of a base machine. A pallet for transporting construction materials, comprising: mounting means; the mounting means being attached to a lower side of the mounting plate, and being installed adjacent to fixing pieces respectively provided on both upper sides of the blade. Mounting pieces;
A mounting piece attached to a lower side of a rear end of the mounting plate and installed adjacent to a fixing piece attached to each of the left and right blade operation frames; and both the adjacent fixing piece and the mounting piece. A fixing pin inserted into a pin hole; and the mounting means is provided integrally with a lower surface of the mounting plate and has a fitting groove formed below; And a tightening screw for tightening and fixing the blade to be inserted into the fitting groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral A denotes a base machine, in which an upper revolving superstructure 2 turns with respect to a lower traveling superstructure 1. An arm 5 is pivotally attached to the upper revolving superstructure 2 of the base machine A via a boom 3 and a slide arm 4 or the like, so that the arm 5 can be freely moved up and down (turned up and down). Note that the slide arm 4 may be omitted. In this case, the arm 5 is pivotally attached to the tip of the boom 3. At the tip of the arm 5,
A gripping device C is detachably mounted via a mounting jig B.

[0007] A blade 7 is provided on the front portion of the lower traveling body 1 of the base machine A via an operation frame 6 so that various earthwork can be performed. A pallet D for transporting materials is detachably attached to the blade 7. 2 and 3, the pallet D includes a mounting plate 8, mounting pieces 9 attached to both lower surfaces of the mounting plate 8, and a rear end of the mounting plate 8. And mounting pieces 10 attached to both sides of the lower surface. These mounting pieces 9 and 10 are provided with pin holes 9a and 10a, respectively. The placing plate 8 has a width substantially equal to the lateral width of the blade 7 of the base machine A, and has a width in which a number of concrete secondary products such as masonry blocks can be arranged. It is preferable to attach a non-slip material such as a rubber plate to the upper surface of the mounting plate 8 so that the product does not slide down.

Accordingly, in order to mount the pallet D to the blade 7, the mounting piece 9 of the mounting plate 8 is placed adjacent to the fixing piece 11 attached to both sides of the front upper portion of the blade 7 and The mounting piece 10 of the mounting plate 8 is installed adjacent to the fixing piece 12 attached to the operation frame 6. These fixing pieces 11, 12 and the pin holes 11 of the mounting pieces 9, 10
Fixing pins 13 and 14 are inserted into a, 12a and 9a and 10a, respectively, and the pallet D is attached and fixed to the blade 7 and the operation frame 6.

Since the apparatus of this embodiment is configured as described above, for example, when performing masonry work by this apparatus, first, the gripping device C is mounted on the arm 5 of the base machine A. By the way, since a bucket is usually attached to the arm 5, the bucket is removed from the attachment / detachment jig B, and then the gripping device C is attached to the attachment / detachment jig B. As described above, the pallet D for transporting materials is attached to the blade 7 provided at the front of the lower traveling body 1 of the base machine A.

When the above preparation work is completed, the base machine A is moved to the stocking location of the masonry block,
The blocks are gripped one by one by the gripping device C, arranged on the mounting plate 8, and transported to the masonry work position. Upon arriving at the site, the block on the mounting plate 8 is again gripped by the gripping device C and moved to the installation position. When moving the block, the base machine 1 may be moved by the lower traveling structure 1a or the upper revolving structure 1b may be moved as necessary.
Can be turned, and the boom 3, the arm 5 and the like can be operated auxiliary.

FIG. 5 shows another embodiment of the means for mounting the pallet D, which comprises a support 15, a fitting groove 15a, a tightening screw 16, a tightening plate 16a, and an operation frame 16b. Have been. The support 15 is integrally attached to the lower surface of the mounting plate 8. A fitting groove 15a is formed in a lower part of the support body 15 so as to be opened downward. The fitting groove 15a is formed to penetrate both sides of the support 15. The front surface of the fitting groove 15a that abuts on the front curved surface 7a of the blade 7 is a convex curved surface following the curved surface. The tightening screw 16 is screwed into a screw hole formed through the outside of the support 15 and the inside of the fitting groove 15a. The fitting groove 15a of the tightening screw 16
A fastening plate 16a is attached to the inner end. The tightening plate screw 16a is mounted in a loosely fitted state so as to freely rotate with respect to the tightening screw 16. The tightening screw 16
An operation rod 16b is attached to an outer end of the screwdriver to rotate the tightening screw 16.

[0012]

[Effects of the Invention] The mounting plate of the pallet can be attached and detached very simply and quickly only by operating the fixing pins and pulling out and rotating the tightening screws.
