Description

(54) ZAKHVDT-KANTOVATEL FOR ROLLS OF SHEET

BECOME

 This invention relates to lifting devices designed, in particular, for gripping and canoeing heavy ponos, e.g. sheet steel.

Known gripper for coils of sheet steel containing a traverse, a supporting frame connected to it, gripping levers mounted on the frame, provided with a mechanism for fixing their position, and a turning mechanism including a drive mounted on the frame connected to the frame via a chain transmission Ij.

However, this device is unreliable in operation due to the absence of a power drive for gripping levers.

The closest to the proposed technical essence is a gripper for turning coils of sheet steel, containing a traverse, connected to it by a nonsugging ryoma with back jaws, one of which is rigidly fixed to the frame, and the other: screw drive connected to the gearbox 2.

The disadvantage of lime devices is low productivity

work due to the slow transfer of the clamping jaws, which is caused by the need to create a large clamping force.

The purpose of the invention is to increase productivity by accelerating the process of seizing cargo.

The goal is achieved by the fact that the positioner is equipped with

10 additional screw drive, hinged on the frame and connected by means of levers to the gearbox, which is mounted on the levers eccentric, and clamping sponge

15 is connected to the main screw drive pivotally.

FIG. 1 shows the proposed gripper-tilter, general view; in fig. 2 is a view along arrow A in FIG. one;

20 in FIG. 3 - kinematic scheme. Capture-tilter.

The gripper-tilter contains a supporting frame 1, on which, by means of axis 2, a double-arm lever 3, 25 is mounted on one shoulder of the second hinge

the clamping jaw 4 is fixed, and the other is connected to the screw gear 5 connected through the gearbox 6 to the engine 7. On the frame l in the pins 8

30 pivotally mounted additional screw drive 9, connected to the main drive by levers 10 and 11, located symmetrically along both CTopoHciM gearbox B. The ends of the levers 10 and 11 are interconnected by a cross member 12, which is pivotally attached to the screw 13 of the drive 9. Reducer b through the pins 14 eccentric. but attached to the other end of the levers 10 and 11. The second clamping jaw 15 is rigidly fixed on the frame 1. The frame 1 is suspended on flexible rods, for example chains 16, bending 17 sprockets 18 mounted on the yoke 17, kinematically connected to the drive 19, fixed on the yoke 17. On the yoke 17, the cheeks 20 are secured with an axis 21 for hanging on the hook of the lifting means. Capture-tilter works as follows. . A hook-lifting device hooked onto a hook is placed above a roll of steel sheet, and a fixed clamping jaw 15 is inserted inside the roll, so that the frame 1 abuts against the end surface of the roll; Then, the main screw actuator 7 is turned on, which, acting on the double-arm lever 3, selects the gap between the roll and the clamping sponge 4, while preloading the turns of the roll. When the main drive is turned off, an additional screw drive 9 is automatically turned on, which, acting on the levers 10 and 11, moves the screw gear 5 together with the gearbox housing 6 due to the eccentric mounting of the gearbox and thereby adjusts the roll force to the necessary. Upon reaching the required force, the additional screw actuator 9 is automatically turned off and thereby gives a signal allowing the lift. During the lifting of the gripper with the roll and its transportation, if necessary, the roll can be tilted by means of a drive 19, at the place of installation the roll is laid in the required position, the jaws are opened and the roll is dispensed. Thus, due to the presence of two drives, the load is quickly captured with the effort required to ensure reliable operation, which increases the productivity of the work. Claim capturing device for coils of sheet steel, comprising a spreader, a supporting frame connected to it with clamping jaws, one of which is rigidly fixed to the frame, and the other is movable and connected to a screw drive connected to a gearbox, characterized in that in order to increase productivity by speeding up the process of slinging cargo, it is equipped with an additional screw drive mounted on the frame and connected by means of levers to a gearbox, which is mounted on the levers eccentrically, and the clamping sponge is pivotally connected to the main screw nature.
