Fi8.1

The invention relates to preparatory transport equipment, in particular, to load handling devices.

The aim of the invention is to increase reliability and simplify the design.

In Fig.1 schematically shows the proposed lifting device at the time of the seizure of the cargo, a general view; in FIG. 2, a load gripping device, side view; on fig.Z - lifting device in the open position.

The load gripping device comprises a L-shaped pickup lever 1, an angular lever 2, a double-hinged bar 3 and an emphasis 4 with a bracket 5. The triangular lever 2 is articulated using the axis 6 with an L-shaped pickup lever 1 and is equipped with a figured direction 7, which is made with a loop of the closure 8 and the opening 9. The figure 10 freely moves the suspension 10, which is intended to hang the load gripping device on the hook of the load lifting machine. The lower end of the catch lever 1 is provided with shoulders 11.

An emphasis 4, a bracket 5 with its middle part is pivotally connected by means of a horizontal axis 12 to an angular lever 2. The end of bracket 5 is connected to a pick-up lever 1 by means of axes 13 and 14 and two tons of g 3.

The proposed device works as follows.

Before starting work, the suspension 9 is transferred to the opening loop 8 and is hung on a hook of a lifting machine, then the device is raised. The angular lever 2 rotates around the axis b and releases the cavity to accommodate the load unit. In the open state, the device is lowered onto the lifted unit, after which the suspension 10 is transferred to the closure loop 8 and the hook is raised (Fig. 1).

Under the influence of the force generated by the hoisting rope, the rotation of the angular lever 2 and the stop 4 associated with it begins. The stop 4 moves downward, while ensuring that its pressure surface is parallel to rex

until it comes in contact with the lifted load. At the same time, the shoulders 11 of the pick-up lever 1 slide along the side of the block.

During the further lifting of the hook, the shoulders 11 will enter the kerf separating the block from the mineral array, and the block is clamped securely in the load gripper. After that, the block is lifted and loaded into the vehicle.

To unload the lifting device, it is lowered onto the surface of the receiving platform. Lowering hook

prior to contact of the block with the surface of wedges or pads installed on the receiving platform. Then, the suspension 10 is transferred to the loop 9, opened by lifting the hook

lifting device and remove it from the block.
