(54) AUTOMATIC LOADING DEVICE

(57) The invention relates to the field of lifting and transport machinery. The purpose of the invention is to improve ease of operation. The device contains a frame with guides with a relief surface 5, in contact with the links of the stub-roller chain attached to the lifting and lowering body 8o. When the slide is advanced with the gripping body, the links of the stub-roller chain unfold until it stops at the relief surface 5 and is fixed in the guide. 1 il.

The invention relates to a lifting machinery industry and can be used in areas where lifting devices are used.

The aim of the invention is to improve ease of operation.

The drawing shows the proposed

automatic load handling device with seized cargo and transportation, general view.

The automatic load gripping device has a housing 1, sliders 2 (only one slider is shown in the drawing) with wedge gripping elements 3, guides 4 with a relief surface 5, flexible rods 6, yoke 7 with a lifting and lowering body 8, perform additional functions cargo and hooks 9, a locking mechanism consisting of a bell 10, a cylindrical guide 11 mounted on the housing 1, and a movable conical reflector 12, the surface 5 has inclined towards the extension

Automatic lifting device operates as follows.

The lifting mechanism (not shown) of the yoke 7 is lowered to a position where the hooks 9 with their hooks will be below the bell 10. When lifting the yoke 7, the hooks 9 are picked up by the bell 10 fixed rigidly on the cylindrical guide 11; the load handling device rises and is transferred to the cargo cavity (not shown, the yoke 7 is lowered until it is grasped by hooks 9 of the conical reflector 12, installed with the ability to move along the cylindrical guide 11; the bell 10, the hook hooks 9, slipping from the conical reflector 12, bypass the bell 10.

When the crosshead 7 with the organ 8 is further lifted, the flexible rods 6, fixed at one end on additional load 8, and the other on slider 2, begin to move along guide 4, pushing the gripping bodies up to the stop with wedge gripping elements 3 into the stop surface along - VMNSHI Order 531/18

tated.

To release the captured cargo, it is lowered to the floor, the traverse 7 is lowered with additional cargo.

And 8, which moves the flexible rods 6, withdraws them from jamming, the gripping bodies are displaced to the center, the wedge gripping elements 3 release the load. The presence of a relief surface in guides, which enclose flexible rods, and the ability of elements of flexible rods to wedge from the force generated by the wedge gripping elements, makes it possible to reliably capture and transport a load that is significantly superior in weight to the load gripping device,
