SU151787A1 - Tick-grip for cylindrical cargo with an internal axial cavity - Google Patents

Description

Tick-borne grippers for lifting loads having a cylindrical shape with an inner axial cavity, mainly rolls of sheet material, equipped with clamps that cover the load from the inner and outer sides are known.

A constructive feature of the described grip is that the clips holding the load from the inside are made in the form of U-shaped brackets, which are hingedly fixed on the castors in one diametrical plane and their internal vertical extremities are interconnected by a pin having a limited radial movement. In order to release the load in the tick-borne lock, the latch has been replaced by a tick. Clamps in such a vypolienii more reliably seize the goods.

The drawing shows the described grip in two projections.

The grip consists of a double castor /, which is pivotally connected to a single U-shaped brace 2, a single castor 3, which is also parchingly connected to a double U-shaped brace 4. Both brackets are interconnected by a plastic 5 and may slightly shift due to the presence of an extended groove single overhang. Such an offset is necessary in order to be able to install the grip on a roll with small variations in its internal diameter. To the upper ends of the castors, a double ha 6 and a single 7 ha, which are connected to the cargo bracket 8 by the hook 9, are fixedly hinged. At the latter, the lateral latch 10 swings freely (along the grip). The latches of the latch are limited by the guide bar 11. To the lower The ends of the double-shouldered castors are pivotally fastened with the shoulder-bars 12. In addition, brackets 13 and stops 14 are welded to the castors to limit the movement of the U-shaped brackets relative to the casting iron when lifting the gripper without a load.

Tick-borne grip for the bracket 8 visit on the hook of the crane. In this case, the latch 10 is hooked onto the pin 5, so that a gap is created between the U-shaped brackets 2 and 4 by the shoes 12, which is necessary to set the grip on the roll. As the hook of the crane is further lowered, the upper part of the grip is lowered, and the locking latch 10 is removed from the hook with the pin 5. Then the roll is pressed, which is firmly clamped between the U-shaped brackets 2 and 4 and the shoes 12.

To release the load after installing the roll into place, the upper part of the grip is lowered until the gap of the taller latch 10 is lower than the pin 5. When the grip is lifted again, the latch automatically rests against the pin 5 and holds the castors / and 5 and brackets 2 and 4 in the unlocked position.

Claims (2)

1. Tick-borne gripper for cargo of a cylindrical shape with an internal axial cavity, for example, rolls of sheet material, provided with a clamp, with cargo weights covering it from the inside and outside sides, characterized in that, in order to increase reliability of gripping, clips holding the load from the inside are made in the form of U-shaped brackets hinged on castor brackets that are located in the same diametral plane, the inner extremities of which with cut corners are connected with each other by a pin having a limited radial movement. 2. Use in the tick-borne gripping according to claim 1 for releasing the cargo of the tandem latch.
