(54) CAPTURAL DEVICE FOR LIFTING PRODUCTS

one

The invention relates to lifting equipment, namely, load handling devices with elements expanding inside hollow articles, and can be used during assembly and disassembly work, and especially by divers during underwater repair of ships.

A device for lifting articles with an internal cavity is known, comprising a rod with hingedly gripping bodies, having a loop at one end for hanging onto a hook of a lifting mechanism, and at the other end a wedge interacting with the gripping bodies. The loop is mounted with the ability to move relative to the axis of suspension of the gripping bodies for fixing which is the spring P.

A disadvantage of the known device is the complexity of the design.

The purpose of the invention is to simplify the design. WITH INNER CAVITY

This goal is achieved by the fact that: KLIN is made with a hole through which a spring is passed, fixed on the axis of suspension of the gripping bodies.

FIG. 1 shows a general view of the device; in fig. 2 - the same, side view; in fig. 3 is a view A in FIG.

Pickup device contains

10 rod 1, gripping bodies 2 and 3, the axis k and the spring. 5. Rod 1 consists of two cheeks 6 and 7, having in the upper part a loop 8 for hanging on a lifting hook

15 mechanism, and in the lower part - a wedge 9 and a slot 10, in which the axis k is placed. The gripping bodies 2 and 3 in the form of paws are suspended to the axis and the spring 5 is attached, having in the initial

th position ring-shaped. The spring is threaded into the hole 11 of the shank 12 of the wedge 9 and forms loops 13 and 1A.

The device works as follows.

The gripping bodies 2 and 3 in the closed position are inserted into the hole of the part. During the compression of the loop I, the spring 5, the wedge 9, together with the rod 1, under the force of opening the loop 13 moves towards the k axis against the stop with the gripping bodies 2 and 3, pushing them apart. The paws, with their hooks, engage the hole or slot of the lifted part. When the hinge is released due to the elastic force of the spring 5, the wedge 9 is fixed in the stop position, and the axis 4 of the suspension of the gripping bodies 2 and 3 slides along the slot 10 of the cheeks 6 and 7 of the rod 1, the device which has been buried by the loop 8 provides lifting of the part with lifting means. When the part is lifted, the wedge 9 additionally pushes the gripping bodies 2 and 3, thus ensuring a secure grip of the part. In the case of involuntary lowering of the part to be dismounted onto the hard surface of the loop 13 of the spring 5, it does not allow the wedge 9 to slide, keeping bodies 2 and 3 open . To detach the part, loop 13 is removed, as a result of which the shank 12 of the wedge 9 is moved in the opposite direction, shear bodies 2 and 3. The fixture is pulled out of the part hole.

The effectiveness of the proposed device lies in the possibility of using pro in cramped conditions. any spatial position, which leads to a reduction in the time of installation and dismantling works during underwater ship repair.
