Description

one

The invention relates to the building materials industry and is intended to deliver wall stone.

A pallet for lifting cargo is known, including a base with two double-arm levers connected to a sling and with a flexible element that seizes the load when it is lifted 1.

The disadvantage of the device is the impossibility of mechanized loading and unloading of wall stone from the pallet.

Closest to the present invention is a pallet for delivering stone, comprising a base with limiters and rotating frames fixed on it with horizontal and connecting rods, while the frames are interconnected by a tensioning device 2.

The disadvantage of the device is the tight laying of the stone on the pallet, as a result of which it is impossible to ensure the mechanized loading and unloading of the stone on the pallet.

The purpose of the invention is to provide mechanized loading and unloading of stones on a pallet.

This goal is achieved by the fact that in a device that includes a base with limiters and pivoting frames fixed on it with horizontal and connecting rods, the base is made with inclined platforms and additional limiters; and the connecting rods are made in the form of a polygon, with additional stops and connecting rods located

to at a distance from each other equal to the width of the row of the packaged stone.

FIG. 1 shows the pallet in the transport position with a load; in fig. 2 - pallet at the time of loading; in fig. 3 - pallet at the time of lifting; in fig. 4 - sub5 dong in the transport position without load. The pallet contains a base 1 with inclined platforms 2 (solid or lattice), pivoting frames 3, hinges fastened to Hai 4. Pivoting frame

20 3 is made of a horizontal rod 5 and cargo loops 6 mounted on connecting rods 7. The connecting rods are made either as a linear rod 7 or a linear rod with additional rods 8 and 9. The rods 7, 8 and 9 form a polygon, or As a special case, a triangle.

The base 1 along the perimeter of the installed p Yes stones has a main and an additional limiter for moving the stone 10. The hinges of the rotary frame 4 are located on the same axis of rotation 11. The load loops 6 are mounted on the connecting rods 7, so that they are in the loaded state below the top package level. The number of connecting rods 7, 8 and 9 depends on the number of rows of stones in the package and exceeds it by one unit. The pallet also has support-guide elements 12, made in the form of squares, which contribute to the stability of the pallets with their multi-layered arrangement.

Pallets are used as follows.

The pallets are transported to the quarry in the transport position. At the face-to-face area, the swivel frames 3 are lifted, the wall stone is loaded onto the pallet in rows, then the frames 3 are rotated, limiting the lateral displacement of rows of stones on the pallet. The longitudinal movement of the stone prevents its placement on the sloped platforms 2 of the base 1.

After the pallets are delivered to the destination, the turning frames 3 are lifted and the stone is unloaded in a mechanized manner.

The proposed device allows for mechanized loading and unloading of wall stones on a pallet.
