Description

Technical Field

[0001] This utility model relates to the field of rolling mill production technology, specifically to a rotatable rolling mill production lifting fixture structure. Background Technology

[0002] Rolls are core components in metal rolling processes, typically made of high-strength alloy steel or cast iron. They are categorized into work rolls, support rolls, etc. Their surfaces require heat treatment to improve wear resistance and precision grinding to ensure a smooth finish. Key parameters include roll diameter, roll length, and hardness. The main structure of a roll is cylindrical, requiring specialized lifting equipment for hoisting. Traditional lifting equipment only allows for vertical movement of rolls, resulting in poor angular adaptability after transportation. Utility Model Content

[0003] The purpose of this utility model is to provide a rotatable roll production lifting device structure to solve the problem mentioned in the background art that when traditional lifting devices are used to lift rolls, the rolls can only move vertically up and down, resulting in poor angular adaptability of the transported rolls.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotatable roll production lifting device structure, including a main housing, with lifting end plates at both ends of the main housing, and lifting seats at the lower ends of the two lifting end plates. Lifting pins are rotatably connected to the interior of each lifting seat via bearings. A secondary housing is located above the middle of the upper surface of the main housing, with lifting connecting seats at both ends of the secondary housing. A lifting rod is located at the upper end of the interior of each lifting connecting seat. The outer ring of a slewing bearing is fixedly connected to the middle of the upper wall of the main housing via bolts. The inner ring of the slewing bearing is fixedly connected to the lower surface of the secondary housing via bolts passing through washers. A servo motor is bolted to the lower end of the outer ring of the slewing bearing, and the power output end of the servo motor meshes with the inner ring of the slewing bearing via gears.

[0005] Preferably, the lifting base is fixedly welded to both sides of the lifting end plate, and a limiting end plate is provided at the lower inner end of the lifting base and below the lifting end plate, and the lower end of the lifting pin abuts against the limiting end plate.

[0006] Preferably, a fixing plate is provided on the lower surface of the outer ring of the rotary bearing, and the servo motor is fixedly connected to the outer ring of the rotary bearing by bolts passing through the fixing plate.

[0007] Preferably, both the auxiliary housing and the washer have through holes at their middle positions, and the through holes are connected to the inner cavity of the main housing through the slewing bearing.

[0008] Preferably, both of the lifting end plates are inverted U-shaped structures, and a connecting rod is provided between the front and rear ends of the two lifting end plates and above the lifting base.

[0009] Compared with the prior art, the beneficial effects of this utility model are: on the basis of the traditional lifting device structure, an adjustment structure for the roll angle is integrated. When the roll is lifted, the roll can move vertically up and down. The servo motor drives the slewing bearing to rotate, so that the auxiliary box and the main box rotate relative to each other, thereby improving the roll angle adaptability after transportation.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides a rotatable roll production lifting fixture structure, including a main housing 1. Both ends of the main housing 1 are provided with lifting end plates 2. The lower ends of both lifting end plates 2 are provided with lifting seats 3. Lifting pins 4 are rotatably connected to the interior of each lifting seat 3 via bearings. A secondary housing 5 is located above the middle of the upper surface of the main housing 1. Lifting connecting seats 6 are located at both ends of the secondary housing 5. Lifting rods 7 are located at the upper end of the interior of each lifting connecting seat 6. The outer ring of a slewing bearing 8 is fixedly connected to the middle of the upper wall of the main housing 1 via bolts. The inner ring of the slewing bearing 8 is fixedly connected to the lower surface of the secondary housing 5 via bolts passing through washers 9. A servo motor 10 is bolted to the lower end of the outer ring of the slewing bearing 8. The power output end of the servo motor 10 meshes with the inner ring of the slewing bearing 8 via gears.

[0018] In use, the auxiliary housing 5 is rotatably connected to the main housing 1 via a slewing bearing 8. A lifting connection seat 6 is installed at the upper end of the auxiliary housing 5, and a lifting rod 7 is installed inside the lifting connection seat 6. The entire lifting device is connected to the lower part of the lifting equipment by binding and fixing the cable of the external lifting equipment to the lifting rod 7. Lifting end plates 2 are installed at both ends of the main housing 1, and a lifting seat 3 is installed at the lower end of the lifting end plate 2. A lifting pin 4 is installed inside the lifting seat 3. The roller is connected to the lifting device by directly engaging the lifting pin 4 with the support equipment of the roller. At the lower end, the hoisting equipment lifts the roll using the overall lifting device. The servo motor 10 meshes with the inner ring of the slewing bearing 8, causing the inner and outer rings of the slewing bearing 8 to rotate relative to each other. The outer ring of the slewing bearing 8 is fixedly connected to the main housing 1 by bolts, and the inner ring of the slewing bearing 8 is fixedly connected to the auxiliary housing 5 by bolts through the washer 9. This causes the main housing 1 to rotate relative to the auxiliary housing 5, thereby adjusting the angle of the roll. The washer 9 ensures that there is a gap between the auxiliary housing 5 and the main housing 1, preventing interference during rotation.

[0019] The lifting base 3 is fixedly installed on both sides of the lifting end plate 2 by welding. The lower end of the lifting base 3 and below the lifting end plate 2 is provided with a limiting end plate 11. The lower end of the lifting pin 4 abuts against the limiting end plate 11, thereby blocking the rotation of the lifting pin 4 and thus locking the support structure of the roll.

[0020] The lower surface of the outer ring of the rotary bearing 8 is provided with a fixing plate 12. The servo motor 10 is fixedly connected to the outer ring of the rotary bearing 8 by bolts passing through the fixing plate 12. By setting the fixing plate 12, the servo motor 10 is connected to the lower end of the outer ring of the rotary bearing 8.

[0021] Both the secondary housing 5 and the washer 9 have through holes 13 in the middle. The through holes 13 are connected to the inner cavity of the main housing 1 through the rotary bearing 8. By opening the through holes 13 in the lower wall of the secondary housing 5, the cable controlling the servo motor 10 can be extended into the interior of the main housing 1 through the secondary housing 5 and connected to the servo motor 10.

[0022] Both of the lifting end plates 2 are inverted U-shaped structures. A connecting rod 14 is provided between the front and rear ends of the two lifting end plates 2 and above the lifting base 3. The strength between the two lifting end plates 2 is improved by setting the connecting rod 14.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
