Description

Technical Field

[0001] The utility model relates to the technical field of hoisting machinery, in particular to a roll changing tooling for a squeezing roll. Background Art

[0002] During the cold rolling production process, the squeezing roll needs to be replaced regularly. The squeezing roll is very heavy and requires multiple people to cooperate with a crane for hoisting and handling. When hoisting, the two ends of the squeezing roll need to be tied with steel wires first, and then the crane is used to lift it. This process is very dangerous. For squeezing rolls of different lengths, steel wires of corresponding different lengths need to be set. If the lengths of the steel wires tied to both sides of the squeezing roll are different, once the squeezing roll tilts, it will cause major accidents and improvement is needed. Content of the Utility Model

[0003] To solve the problems mentioned in the background art, the purpose of the utility model is to provide a roll changing tooling for a squeezing roll.

[0004] To achieve the above object, the technical solution of the utility model is as follows:

[0005] A roll changing tooling for a squeezing roll includes a cross arm, a strip-shaped plate, a connecting block, a screw rod and a fixing nut. A lifting ring is connected to the middle of the top of the cross arm, and the lifting ring is used to hang the cross arm on the hook of a hoisting device. There are two strip-shaped plates. The first end in the length direction of the strip-shaped plate is movably sleeved on the cross arm, and the second end in the length direction of the strip-shaped plate is in the shape of a hook. Connecting blocks are connected to both ends in the length direction of the cross arm through bolts, and the bottom of the connecting block extends below the cross arm. A screw rod is detachably installed between the lower parts of the two connecting blocks. The screw rod penetrates through the two strip-shaped plates, and a fixing nut is threadedly connected to each end of each strip-shaped plate on the screw rod.

[0006] The beneficial effect of the utility model is that the bottom of the strip-shaped plate is in the shape of a hook, which can lift the squeezing roll, change the distance between the two strip-shaped plates, so as to adapt to squeezing rolls of different lengths, and then use the fixing nut to fix the position of the strip-shaped plate, so that the squeezing roll cannot shake between the two strip-shaped plates, ensuring the stability of hoisting. Description of the Drawings

[0007] Figure 1 It is a schematic structural diagram of an embodiment of the utility model.

[0008] Explanation of the drawing reference numbers: 1, cross arm; 11, lifting ring; 2, strip-shaped plate; 3, connecting block; 4, screw rod; 5, fixing nut; 6, anti-loosening nut. Detailed Embodiment

[0009] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention shall fall within the protection scope of the present invention.

[0010] As Figure 1 shown, a roll-changing tooling for a squeezing roll includes a cross arm 1, strip plates 2, connecting blocks 3, screw rods 4 and fixing nuts 5. A lifting ring 11 is connected to the middle of the top of the cross arm 1. The lifting ring 11 is used to hang the cross arm 1 on the hook of a lifting device. There are two strip plates 2. The first ends in the length direction of the strip plates 2 are movably sleeved on the cross arm 1. The second ends in the length direction of the strip plates 2 are in the shape of hooks. Connecting blocks 3 are connected to both ends of the cross arm 1 in the length direction through bolts. The bottoms of the connecting blocks 3 extend below the cross arm 1. A screw rod 4 is commonly penetrated through the lower parts of the two connecting blocks 3. Anti-loosening nuts 6 are threadedly connected to both ends of the screw rod 4 in the length direction. The anti-loosening nuts 6 abut against the connecting blocks 3. The screw rod 4 penetrates through the two strip plates 2. Four fixing nuts 5 are threadedly connected to the screw rod 4. The four fixing nuts 5 are arranged in pairs. A strip plate 2 is clamped between each pair of fixing nuts 5.

[0011] In actual use, first, according to the length of the squeezing roll, the distance between the two strip plates 2 is changed. Then, the positions of the strip plates 2 are fixed by using the fixing nuts 5. The shaft heads at both ends of the squeezing roll can be hooked by the hooks at the bottoms of the two strip plates 2, so as to lift the squeezing roll. Since the gap between the two strip plates 2 is adjusted, the squeezing roll cannot shake between the two strip plates 2, ensuring the stability of the hoisting.

[0012] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. All any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
