Description

Technical Field

[0001] This utility model relates to the field of rolling mill crossbeam technology, specifically to a rolling mill crossbeam maintenance auxiliary device. Background Technology

[0002] As the core area for assembling and preparing rolling mills for both production lines, the assembly workshop of the steel rolling mill directly impacts the overall production process through its production rhythm and equipment maintenance efficiency. During online operation, the rolling mill is constantly exposed to a humid environment and in continuous contact with circulating turbid water. This harsh condition causes wear and tear on equipment components. On one hand, the humid environment makes various parts of the rolling mill highly susceptible to rust, especially critical load-bearing and transmission components such as crossbeams. Rust not only weakens their structural strength but also affects assembly accuracy. On the other hand, the circulating turbid water contains a large amount of suspended particulate matter, which easily accumulates in the gaps of the crossbeam dovetail supports. If not cleaned promptly, this directly prevents the crossbeams from moving smoothly laterally, leading to rolling mill malfunctions and severely restricting production continuity.

[0003] To address the aforementioned issues, after each roll comes off the production line, the mill crossbeams require maintenance work such as rust removal and oiling. The mill crossbeams are frame structures; during maintenance after disassembly, all four sides of the main frame must be thoroughly treated. Currently, the crossbeam maintenance process relies on overhead cranes to rotate them, allowing for oiling and other operations on different surfaces.

[0004] However, this frequent hoisting method not only makes the entire maintenance process cumbersome and consumes a lot of manpower and time, but also results in low maintenance efficiency, making it difficult to meet the high-efficiency production needs of the assembly workshop. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for the maintenance of rolling mill crossbeams, so as to solve the problems of cumbersome procedures, high manpower and time consumption, and low maintenance efficiency in the process of hoisting crossbeams.

[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: a rolling mill crossbeam maintenance auxiliary device, including a base plate, two support seats on the base plate, brackets on the two support seats, a motor on one side of the brackets, and a rotating shaft one and a rotating shaft two rotatably connected to the two brackets. One end of the rotating shaft one is fixedly connected to the motor, and the opposite ends of the rotating shaft one and the rotating shaft two are provided with a clamping structure for clamping the crossbeam.

[0007] The working principle of this utility model is as follows: A rolling mill crossbeam maintenance auxiliary device, when the crossbeam needs maintenance, firstly, the crossbeam is placed in the clamping structure, and the clamping components firmly clamp it. Then, the crossbeam is derusted and oiled for maintenance. During the maintenance process, when different surfaces of the crossbeam need to be treated, the motor on one side of the support is started. The motor drives the first rotating shaft to rotate, and the first rotating shaft drives the crossbeam to rotate synchronously through the clamping structure. The crossbeam then drives the second rotating shaft to rotate on the support, realizing the autonomous flipping of the crossbeam, which facilitates the workers to perform derusting and oiling operations on each surface of the crossbeam.

[0008] The beneficial effects of this utility model are as follows: by setting up a base plate, support seat, bracket, motor, rotating shaft one, rotating shaft two and clamping structure, it is convenient to rotate and apply oil during the maintenance of the mill crossbeam. The motor can drive rotating shaft one to rotate, and then drive the crossbeam and rotating shaft two to rotate through the clamping structure, so as to realize the autonomous rotation of the crossbeam without relying on the overhead crane for rotation, effectively simplifying the crossbeam maintenance process, reducing the consumption of manpower and time, and improving maintenance efficiency.

[0009] Option 2, a preferred embodiment of the basic option, includes a clamping structure comprising a U-shaped support rod and a U-shaped telescopic rod. One side of the U-shaped support rod has a groove for sliding connection to the U-shaped telescopic rod. Both sides of the U-shaped telescopic rod have through holes for bolting the U-shaped support rod, with at least five through holes evenly spaced. An L-shaped rod is detachably connected to the side of the U-shaped support rod away from the U-shaped telescopic rod. The U-shaped telescopic rod has a locking assembly for clamping the crossbeam. The U-shaped telescopic rod slides within the groove of the U-shaped support rod. Combined with the multiple sets of evenly spaced through holes, the relative positions of the two can be flexibly adjusted via bolt connection, thus adapting to rolling mill crossbeams of different lengths and enhancing the versatility of the device. The locking assembly securely clamps the crossbeam onto the U-shaped telescopic rod, preventing wobbling during crossbeam rotation.

[0010] Option 3, a preferred embodiment of Option 2, includes two opposing fixed seats, which are fixedly connected to a U-shaped telescopic rod. A rotating shaft 3 is fixedly connected between the two fixed seats. Bearings are provided at both ends of the rotating shaft 3 near the two fixed seats. A rotating rod is provided on the outer ring of the bearing. A limiting unit for limiting the rotation of the rotating rod is provided on one side of each of the two fixed seats. In the locking assembly, the bearings at both ends of the rotating shaft 3 allow the rotating rod to rotate 90 degrees to clamp the crossbeam, and then the limiting unit limits the rotation to prevent the crossbeam from loosening due to accidental rotation of the rotating rod during maintenance.

[0011] Option 4, a preferred embodiment of Option 3, includes two locking rods. Each of the two fixed seats has a limiting groove for limiting the locking rods, and a spring is installed within each groove. One end of each locking rod has a pull rod, and the two fixed seats have a circular hole on the side away from the locking rod for the pull rod to pass through. Under the action of the spring, the locking rods of the limiting unit can limit the rotation rod, achieving initial fixation of the rotation rod without complex operations. When limiting the rotation rod is no longer needed, pulling the pull rod can cause the locking rod to compress the spring and disengage from limiting the rotation rod. Then, the rotation rod can be rotated so that it no longer needs to limit the crossbeam. After completion, releasing the pull rod causes the locking rod to automatically reset and limit again under the spring force.

[0012] Option 5, which is a preferred option of Option 3, has a connecting rod threaded to one end of each of the two rotating rods. The connecting rod is equipped with a disc. The height of the disc can be adjusted by rotating the connecting rod, so that the disc can fit tightly against the surface of the crossbeam and enhance the clamping force on the crossbeam.

[0013] Option 6, a preferred embodiment of Option 2, features two threaded holes on the U-shaped support rod for threaded connection to the L-shaped rod. The L-shaped rod is threaded and threaded with a nut, one side of which rests against the L-shaped rod. By rotating the nut, the height of the L-shaped rod can be adjusted, allowing for flexible configuration of the L-shaped rod according to the support requirements during beam maintenance.

[0014] Option 7, which is a preferred option of the basic option, is provided with casters at the four corners of the bottom of the base plate, and each caster is equipped with a brake pad; the casters at the bottom of the base plate allow the device to be moved to a suitable maintenance position without the need for strenuous handling, thus reducing the difficulty of operation; the brake pads on each caster can fix the device after it has been moved to the target position, preventing the device from accidentally sliding during the maintenance process.

[0017] like Figures 1 to 3 As shown: A maintenance auxiliary device for a rolling mill crossbeam includes a base plate 1, on which two support seats 2 are fixedly connected.

A motor 4 is mounted on one side of each bracket 3. A rotating shaft 5 and a rotating shaft 6 are rotatably connected to the two brackets 3. One end of the rotating shaft 5 is fixedly connected to the motor 4. The opposite ends of the rotating shafts 5 and 6 have clamping structures for holding the crossbeam. The clamping structure includes a U-shaped support rod 7 and a U-shaped telescopic rod 8. One side of the U-shaped support rod 7 has a groove for slidingly connecting the U-shaped telescopic rod 8. Both sides of the U-shaped telescopic rod 8 have through holes 9 for bolting the U-shaped support rod 7. The number of through holes 9 is not less than five, and the through holes 9 are evenly distributed. An L-shaped rod 10 is detachably connected to the side away from the U-shaped telescopic rod 8. The U-shaped support rod 7 is provided with two threaded holes for threaded connection of the L-shaped rod 10. The L-shaped rod 10 is threaded and a nut 22 is threadedly connected to it. One side of the nut 22 abuts against the L-shaped rod 10. The U-shaped telescopic rod 8 is provided with a locking assembly for clamping the crossbeam. The locking assembly includes two opposing fixed seats 11. The two fixed seats 11 are fixedly connected to the U-shaped telescopic rod 8. A rotating shaft 12 is fixedly connected between the two fixed seats 11. Bearings 13 are provided at both ends of the rotating shaft 12 near the two fixed seats 11. The inner ring of the bearing 13 is fixedly connected to the rotating shaft 12. A rotating rod 14 is fixedly connected to the outer ring of the bearing 13. A connecting rod 20 is threadedly connected to one end of the two rotating rods 14. A disc 21 is provided on the connecting rod 20.

[0018] Each of the two fixed seats 11 has a limiting unit on one side opposite to the other for limiting the rotation of the rotating rod 14. The limiting unit includes two locking rods 16. Each of the two fixed seats 11 has a limiting groove 17 for limiting the locking rod 16. A spring 18 is provided in the limiting groove 17. The two ends of the spring 18 are connected to the inner wall of the limiting groove 17. The side of the two fixed seats 11 away from the locking rod 16 has a round hole for the movable through-hole of the pull rod 19. The outer diameter of the spring 18 is larger than the holes through which the pull rod 19 and the locking rod 16 are movable through on both sides of the limiting groove 17. One end of each of the two locking rods 16 is fixedly connected to the pull rod 19. When the rotating rod 14 rotates, the surface in contact with the locking rod 16 is arc-shaped. The rotating rod 14 presses the locking rod 16 along the arc-shaped surface, thereby limiting the rotation of the rotating rod 14.

[0019] An oil collection trough is provided between the two supports 3, and a groove for oil accumulation is provided on the base plate 1. One side of the oil collection trough is open, and the bottom of the oil collection trough and the base plate 1 are inclined towards the opening side to facilitate the accumulation of maintenance oil. An oil discharge port for unloading oil is provided on the bottom side of the base plate 1 near the opening, and a rubber stopper is provided on the oil discharge port. The length of the L-shaped rod 10 when it is extended and retracted to its limit is always less than the height between the U-shaped support rod 7 and the oil collection trough. When the L-shaped rod 10 clamps the crossbeam, the surfaces of the L-shaped rod 10 and the disc 21 that abut against the crossbeam are provided with anti-slip texture.

[0020] The implementation method of this embodiment is as follows: When maintenance of the crossbeam is required, firstly, use the universal wheels 23 at the bottom of the base plate 1 to push the device to the target position, then step on the brake pads on the universal wheels 23 to fix the device. Next, before performing crossbeam maintenance, adjust the clamping structure according to the length of the crossbeam. First, loosen the bolts connecting the U-shaped telescopic rod 8 and the U-shaped support rod 7, and push the U-shaped telescopic rod 8 to slide in the groove of the U-shaped support rod 7. When the relative positions of the two are adapted to the length of the crossbeam, pass the bolts through the through holes 9 at the corresponding positions of the U-shaped telescopic rod 8 and screw them into the U-shaped support rod 7 to complete the fixation of the two. Then, place the crossbeam on the U-shaped telescopic rod 8 and the U-shaped support rod 7. Next, adjust the height of the L-shaped rod 10 by rotating the nut 22 so that the top of the L-shaped rod 10 contacts and clamps the surface of the crossbeam. Then, rotate the rod 14 around the pivot. Rotate 12 towards the crossbeam. Rotating rod 14 will press the locking rod 16 along the arc surface of locking rod 16. Locking rod 16 compresses the spring 18 in the limiting groove 17. Then, rotating rod 14 rotates to the back of the arc surface of locking rod 16. Therefore, locking rod 16 limits rotating rod 14. Then, rotate connecting rod 20 at one end of rotating rod 14 to adjust the position of disc 21 so that disc 21 is tightly against the surface of crossbeam, completing the clamping of crossbeam. Then, perform rust removal and oiling maintenance on crossbeam. During maintenance, when different surfaces of crossbeam need to be treated, start motor 4 on one side of bracket 3. Motor 4 drives rotating shaft 5 to rotate. Rotating shaft 5 drives crossbeam to rotate synchronously through clamping structure. Crossbeam drives rotating shaft 6 to rotate on bracket 3, realizing the autonomous flipping of crossbeam, which facilitates rust removal and oiling operations on each surface of crossbeam by staff.

[0021] During the oiling process, maintenance oil will drip down, and the oil collection tank between the two supports 3 and the groove on the base plate 1 can collect the oil. Since the oil collection tank and the bottom of the base plate 1 are inclined towards the opening, the oil will gather at the opening. After the maintenance work is completed, remove the rubber plug on the oil drain port on the bottom side of the base plate 1 near the opening, and the collected oil can be discharged from the oil drain port.
