Description

The invention relates to a lifting and transport engineering, in particular to load handling devices,

The aim of the invention is to expand the sizes of the load to be captured.

Figure 1 shows the lifting device, adjusted to the maximum size of the cargo; Fig, 2- -JQ is the same, adjusted to the minimum size of the load.

The load handling device comprises a housing 1 with a supporting part 2, made in the form of a prism. In case 1 15

on horizontal axes x 3, connected by an adjusting screw 4 to the right-handed and left-handed threads at the ends, mounted: two shoulders levers 5. Axes 3 are installed in inclined slots 6 of housing 1 .20

The ends of the two shoulders 5 levers

us with t gami 7 using hinges 8,

The plugs 7 are connected to an attachment element 9 to a lifting machine (not shown) by means of a fixed 25 horizontal axis 10 mounted in the vertical slot 11 of the housing 1..The lateral parts of the horizontal axes 3 have transverse threaded holes 12 for the screw 4, 30

Load handling device operates as follows.

Before operation, the device is adjusted to the required size of the load with the help of an adjusting screw 4, When., The horizontal axle 3 is moved with it in inclined grooves 6, shifting or pushing the two shoulders levers 5,

Moving the horizontal axes 3 along inclined grooves 6 allows one to capture the load of any size provided by the design, always below its middle, which ensures its safe hold for transportation.

After adjustment, the grip is locked in the open position. The grab attached to the hook of the lifting machine is lowered by its support part 2 onto the load, unlocked and lifted. At the same time, the attachment element 9, together with the horizontal axis 10, moves upward along the vertical slot 11 and by means of the tongues 7 through the hinges 8 the two shoulders 5 rotate on the axis x 3 and the load is clamped. The device is locked in a closed position and the cargo is transported.

After lowering the load, the gripper is unlocked and the element 9 with the axis 10 under its own weight moves down along the vertical slot 1I and through the cables 7, the axis 8 rotates the two shoulders levers 5 on the axles 3. The two shoulders levers 5 open and the load is released, the gripper is fixed in the open position . The cycle is repeated.

Claims (1)

Claims A load gripping device comprising a body with slots inclined to the vertical axis of symmetry, two-arm levers installed by means of horizontal axes, the upper arms of which are pivotally connected by means of arms, the upper ends of which are connected by a common horizontal axis between themselves and with the element to connect to lifting machine, and locking the position of two shoulders, about T Latching with the fact that, in order to expand the sizes of the load to be seized, in the lateral parts of the horizontal axes of two shoulders. gov transverse threaded holes formed in the upper housing portion is formed a vertical slot in which is the total horizontal axis t r ,, and the device is provided with an adjusting screw, the ends of which are located in the transverse threaded holes horizontal axes of two-armed levers.
