The invention relates to ferrous metallurgy, namely to lifting devices intended for transporting and tilting coils.

The purpose of the invention is to increase the reliability of operation.

Figure 1 shows the device, a general view; figure 2 - the position of the fixed and movable jaws when turning the roll.

The tilting device contains a frame 1 on which, at an angle A5 to the horizon, a shaft 2 is mounted with fixed and movable jaws 3 and 4 fixed on it. The movable sponge 4 is connected by a lever 5 with a hydraulic cylinder 6. A shaft 7 is mounted on the shaft 2, connected by a rail 8 with a rod of a hydraulic cylinder 9 mounted on frame 1. A counterweight 10 is mounted on frame 1 and a hydraulic station 11 is mounted. In addition, the drawings show an eyelet 12 for gripping the hook on a crane, a setting mechanism 13 and a roll 14.

The device works as follows.

The grip is suspended by the eye 12 on the crane hook (not shown). With the help of a crane, the grip leads to a roll 1.4 located on the floor of the workshop. Depending on the parameters of the roll 14, the position of the movable jaw 4 is adjusted by means of the setting mechanism 13. Then, using a crane, the fixed jaw 3 of the gripping device is driven into the hole of the roll 14. From the control panel (not shown) from the hydraulic station 11, the hydraulic cylinder 11 is moved. When moving the hydraulic cylinder rod 6, the lever 5 and the mobile jaw 4 are connected with it. sponge 3 clamps roll 14. Crane with the help of capture roll 14 is lifted to the required height. At the same time, the counterweight 10 balances the shaft 2, the fixed sponge 3 and the hydraulic cylinder 9 located on the opposite side of the frame 1. After lifting the roll 14 to the required height from the hydraulic station

11 include the stroke of the hydraulic cylinder 9. The displacement of the rod of the hydraulic cylinder 9 connected to the rack 8 causes the gear 7 to rotate together with the shaft 2. When

rotation of the shaft 2 180 ° roll 14, hold the fixed and movable jaws 3 and 4, takes the position shown in Fig, 2.

With the help of a crane, roll 14 is installed on the floor of the workshop. The return stroke of the hydraulic cylinder 6 is switched on, at which the movable sponge 4 returns to its original position. The crane lifts the grip above the roll 14. The return stroke of the hydraulic cylinder 9 is turned on, the shaft 2 together with the fixed and movable jaws 3 and 4 fixed to it, returns to its original position.

The use of the proposed device makes it possible to increase the reliability of operation of the grip by reducing the number of hinged joints, as well as to make the most efficient use of the production area.
