Abstract

Use: in hoisting-and-transport equipment. SUMMARY OF THE INVENTION: the load gripping device comprises a hollow arcuate body, gripping bodies located therein, a main crosshead and an additional one with a suspension moving along a guide, a locking mechanism for locking the position of the gripping bodies connected to the main and additional crossheads, and flexible rods, one ends of which mounted on the gripping organs, and others on an additional traverse. 8 ill.

Description

The invention relates to material handling equipment.

Load gripping devices are known which comprise curved gripping bodies that are hingedly connected to each other and to a traverse link.

The disadvantage of these devices is their low reliability.

Closest to the invention is a load gripping device comprising a hollow arcuate body convex upward, a traverse, gripping bodies located in the hollow arcuate body, rods connected by the upper ends to the traverse and the lower ends to the gripping bodies, a suspension and a position locking mechanism gripping bodies including a rotary element and an engagement element with it.

However, this device is also unreliable due to the rapid wear of the hinge assemblies.

The aim of the invention is to increase reliability.

The invention and its distinctive features are that the device is equipped with a vertically arranged guide, rigidly fixed in the central part of the hollow arcuate body for positioning the beam, an additional beam located in the guide under the main beam, while the rods are flexible and located inside a hollow arcuate body, a rotary element of the mechanism for fixing the positions of the gripping organs and the suspension are fixed on an additional traverse, and the engagement element for a rotary member fixed to the main yoke.

those of the laden load with the supporting surface; on Fig - the same, when released from the load ..

The device comprises a hollow arcuate body 1 with arcuate gripping bodies 2 installed in its cavity, connected by flexible rods 4, passed through rollers 3, with a crossarm 5 installed in a guide 6 with grooves 7. in which the ends of the axles 8 of the crosshead 9 having slots 10 are placed and the ends of the axis 11 of the yoke 12, to which a locking mechanism is attached with rotary engagement elements 13 and the suspension 14 for hanging the device on the hook 15 of the lifting machine.

In a static state, the gripping bodies 2, connected by flexible rods 4 to the yoke 9, coupled by the elements 13 to the yoke 12, are in the lowest position.

A device hung by the suspension 14 on the hook 15 of the lifting machine, operates as follows.

When lifting the device, they occupy the extreme upper position of the beam 12, the gripping bodies 2 connected to it by the elements 13 of the beam 9 and connected to it by flexible rods 4.

When lowering the device at the moment of contact with the load 16, the gripping bodies 2, the traverses 9 and 12 occupy the lowest position. In this case, the elements 13 rotate 90 ° and disengage from the traverse 9.

When lifting the device with a load 16, the yoke 12 occupies its extreme upper position, and the yoke 9 and the gripping bodies 2 connected to it by flexible rods 4 remain in the lowermost position.

When lowering the device at the moment of contact of the load 16c with the supporting surface of the cross beam 12 occupies the lowest position. At the same time, the elements 13 pass through the slots 10, rotate 90 ° and enter into engagement with the traverse 9.

When the device is lifted at the moment of release from the load 16, they occupy the extreme upper position of the yoke 12, the yoke bodies 2 connected to it by the yokes 13 of the yoke 9 and the gripping bodies connected to it by flexible rods 4.

Thus, the application of the invention will improve the reliability of the capture of lifted and transported loads.

Claims (1)
