Description

This invention relates to a lifting machinery, in particular, to load handling devices. A: The purpose of the invention is to enhance operational capabilities by providing for the capture of irregularly shaped cargo in cramped conditions.

FIG. 1 shows a load gripping device, the general view of FIG. 2 - the mechanism of fixing the position of;, or two shoulders gripping levers.

The gripping two shoulders levers 1 are pivotally connected on axis 2, the lower; The ends of which, with their working surfaces 3, are directed toward the center, and the upper ones, made equilibrium with the lower ones, are connected by flexible rods 4 to the crossmember 5. At the ends of the ends, the stands are rigidly fixed. 6 with vertical grooves 7 and protrusions 8 in the lower part, moving in vertical guides 9, which are rigidly connected to the axis 2 o. The ends of axis 2 freely move in the grooves 7 of the pillars 6. Axis 2 is fixed on the racks 6 by means of hinged joints 10, n the hinge of which has a support element 11, and at the ends there are hinges 12 pivotally connected to the rods 10, which are limited to move at the ends of the axis 2. The limited movement of the sleeves 12 is necessary in order for them, - moving along axis 2, not to extend beyond the limits of the oblique surfaces of the uprights 6 The sleeves 12 carry horizontal protrusions 13, which interact when fixing j axis 2 with the projections 8 of the uprights 6, which have horizontal bearing surfaces 14 and oblique surfaces

15, the sleeves 12 are spring-loaded springs 16.

Load handling device operates as follows.

When lowering the load into the body of a dump truck, where it is not possible to open the gripping two shoulders of the levers 1, the traverse 5 with the uprights 6 make a forward movement downwards. The ends of the axis 2 fall into the grooves 7 of the uprights 6, the beveled surfaces 15 of the uprights 6 when lowering act on the sleeve 12, which, compressing the spring

16, move to the extreme position, moving along axis 2 until

pillars 6. As soon as the sleeves 12 will be above the protrusions 13, they are under the action of the spring 16 and

the weights of the hinge rods 10 move to the center of the axis 2 and, with their protrusions 13, interact with the horizontal support surfaces 14. After which the device can be lifted. At the same time, the gripping two shoulders 1 are in a weakened, non-working condition, since the flexible rods 4 are weakened, and the working surfaces 3, slipping over the load, are released from it.

Due to the fact that the upper ends of the two-arm gripping levers 1, made equilibrium with the lower ones, together with flexible rods 4 t more than the lower ones, the self-opening gripping two-arm levers 1 occur.

When lowering the device to the next load, an approximate aiming of the support element 10 on the center of the body weight is made. In this case, the gripping two shoulders levers 1 are opened, and their working surfaces 3 are at the level of the supporting element 11 o. When the device touches the load, in any case abrasion occurs to the supporting element 11, which is pushed up by the force of the device’s gravity. The glands 10 act on the sleeves 12 and retracted them to the extreme position, compressing the spring 16, and the protrusion 13 escapes from the interaction with the horizontal bearing surface 14. Further, the yoke 5 with the help of a lifting machine rises up and with it The uprights and the uprights 6 are positioned upwards, placed in the vertical rails of the ix 9. At some point, the tension of the flexible t 4 r, which, acting on the two shoulder arms 1, tightens them. There is a capture of oversize (cargo). In this case, the supporting element is raised above the cargo and does not touch it.

Invention Formula A load gripping device containing a traverse attached to a hook of a lifting machine, connected by a horizontal axis between each other, gripping two shoulders levers, whose upper arms are connected by means of t with a traverse, two of which are arranged in parallel vertical planes and turned into one working surface side, and at least one of which is surrounded by a working surface to the working surfaces of the first, and a mechanism for fixing the position of the gripping two shoulders, which is connected with the traverse This vertical rack is designed to interact with the common horizontal axis of the two-arm gripping levers, characterized in that, in order to expand the operational capabilities by providing the gripping of irregularly shaped cargo in cramped conditions, it is provided with rigid two-arm levers fixed on the horizontal axis symmetrically relative to the center this axis is vertical guides, and the third of the two-arm gripping levers is located between the other two, with In this way, the locking mechanism of the gripping two shoulders additionally includes, installed at the ends of the horizontal axis and spring-loaded bushings with travel stops - horizontal projections, connected by means of hinges with bushings, a supporting element for interacting with the load; and the additional posts are rigidly fixed at the ends of the cross-bar, mounted in the directions of axes and made with vertical grooves to accommodate the horizontal axis of the gripper double-arm tension arms and protrusions at their lower ends on the outer side with respect to the vertical axis of symmetry of the device, having horizontal bearing surfaces for the protrusions of the sleeves and surfaces obliquely angled to them to interact with the free ends of the sleeves
