Description

This invention relates to load handling devices, in particular to barrel grippers for barrels that are attached to a hook.

lifting mechanism.

The aim of the invention is to increase the reliability and safety of work.

FIG. 1 shows the capture, general view; in fig. 2 — a mechanism for changing the position of the gripping levers; in fig. 3 shows section A-A in FIG. 2

The gripper contains a yoke 1, to the ends of which two shoulders are gripped by their two middle shoulders gripping levers 2, the upper ends of which are connected to the hook of the lifting mechanism with the help of hinged bars 3. At the lower ends of the gripping arms 2, gripping jaws 4, one of which is provided with a turning mechanism (canting), are rotatably mounted.

The cross member 1 has a toothed element 5 having lugs 6 connected by a hinge 7 to a point of connection of one of the gripping levers to a hinged draft 3. The toothed element 5 is in engagement with a screw 8 having a handle 9 that is located outside of the grip 9 The screw to 8 is mounted in a hollow body 10, having the ability to move in guides 11 mounted on traverse 1, and is supported on an eccentric 12 having a handle 13.

Capture is as follows.

If it is necessary to grip the barrel, the hook of the lifting mechanism is lowered along with the grip until the gripping jaws 4 are at the level of the grip line on either side of the barrel. Using the handle 9, rotate the screw to 8, after making sure that the handle 13 of the eccentric 12 is raised up (the eccentric gauge rests against the hollow body 10). When the screw 8 rotates, the toothed element 5 rotates and the lever, acting on the gripping lever 2, contributes to the preliminary clamping of the barrel between the gripping jaws 4.

Making sure that the barrel is securely clamped, the handle 13 is turned, as a result of which the eccentric 12 rotates and the hollow body 10 under the action of its weight is lowered, the worm is released to 8 with the gear element 5. Now, when

0 lifting the barrel by grasping with no hold on the gripping levers 2 contribute to clamping the barrel with a force proportional to the weight of the barrel.

When the barrel is lowered to the ground, to unclench the gripping levers 2 with the handle 13, they engage the clutch of the screw 8 with the element 5 and, rotating the handle 9 from the screw 8, help the gripping arms 2 to diverge and release the barrel with gripping jaws 4.

Claims (1)

CAPTURE TURNER FOR GOODS, comprising a traverse, gripping arms pivotally mounted on it, the upper links of which are pivotally connected by rods to the axis hung on the hook of the lifting machine, and the lower ones have rotary gripping jaws, on one of which are mounted a tilting mechanism and a drive mechanism for changing the position of the gripping levers, characterized in that, in order to increase the reliability and safety of operation, the mechanism for changing the position of the gripping levers contains guides fixed to the traverse, placed a hollow body with a drive worm installed in it, a gear element pivotally mounted on the traverse, the teeth of which are engaged with the teeth of the worm, and a rod pivotally attached at one end to the gear element and the other to the upper arm of one of gripping levers, while in the lower part of the guides the drive eccentric is pivotally fixed to interact with the lower surface of the housing.
