Description

Technical Field

[0001] This invention relates to the field of heavy-duty steel straightening machines, specifically a heavy-duty steel straightening roller flipping and locking device. Background Technology

[0002] On ultra-wide and ultra-thick H-beam and track-rolled steel production lines, after a period of use, the straightening rollers and roller rings need to be disassembled and replaced due to wear. Current technology stores groups of straightening rollers horizontally on straightening roller ring frames and uses manual disassembly and assembly. This horizontal disassembly and assembly method is inefficient due to space constraints, significantly limiting the capacity of the steel rolling production line. If the straightening rollers could be rotated 90° for vertical disassembly and assembly, the production capacity constraint could be greatly alleviated. Therefore, developing a heavy-duty steel section straightening roller rotation and locking device and method is an urgent problem to be solved. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a heavy-duty steel straightening roller flipping and locking device. This device uses hydraulic flipping and relies on lever locking, and its maintenance is simple and convenient.

[0004] To achieve the above objectives, the present invention provides a heavy-duty steel straightening roller flipping and locking device, comprising: a storage rack platform; a fixed base fixed on the storage rack platform; two sets of support seats fixed on the fixed base on both sides along the center line of the straightening roller; a flipping platform hinged to the two sets of support seats; and two sets of swing shaft hydraulic cylinders, the tail of which is hinged to the fixed base, and the flat head of which is hinged to the flipping platform; wherein, a straightening roller locking device is provided on the flipping platform.

[0005] Furthermore, the straightening roller locking device includes:

[0006] The locking rod is hinged and fixed to the lug A on the tilting platform; one end of the locking rod is connected to one end of the spring, and the other end of the spring is connected to one end of the support rod; the other end of the support rod is in contact with the bottom surface of the tilting platform.

[0007] Furthermore, the support located on the left side of the center line of the straightening roller is fixed on the fixed base, and the upper part of the support contacts the lower part of the locking rod. The support located on the right side of the center line of the straightening roller is fixed on the fixed base, and the upper part of the support contacts the lower part of the locking rod.

[0008] The flipping and locking process of the heavy-duty steel straightening roller flipping and locking device of the present invention is as follows: First, the piston rods of the hydraulic cylinders of the tail swing shafts located on both sides of the center line of the straightening roller are driven to retract. The flipping platform rotates around the hinge center of the support seats on both sides of the center line of the straightening roller. When the piston rods of the hydraulic cylinders of the tail swing shafts located on both sides of the center line of the straightening roller are fully retracted, the flipping platform flips 90° from the horizontal state to the vertical state. Figure 2As shown, one end of a locking rod located on one side of the centerline of the straightening roller is engaged with a step on one side of the straightening roller. This locking rod is hinged to the ear seat A on this side. The lower part of the other end of the locking rod contacts the support fixed to the base on this side, forming a seesaw structure. The end of the locking rod is connected to one end of a spring, and the other end of the spring is connected to a support rod on this side. This support rod contacts the bottom surface of the tilting platform. One end of a locking rod located on the other side of the centerline of the straightening roller is engaged with the step on the other side of the straightening roller. On the upper side, the locking rod is hinged to the ear seat B on this side. The lower part of the other end of the locking rod contacts the support fixed to the fixed base on this side, forming a seesaw structure. The end of the locking rod is connected to one end of a spring, and the other end of the spring is connected to the support rod on this side. The support rod on this side contacts the bottom surface of the tilting platform. Under the action of the locking rods on both sides, the straightening roller is locked. The locking principle relies on the force principle of the seesaw. The principle is explained by the force analysis of the locking rod on one side. The locking rod is located on one side of the center line of the straightening roller. The force exerted on the locking rod head by the step of the straightening roller causes the locking rod to rotate counterclockwise around the hinge center of ear seat A. The force exerted on the locking rod by the support on this side causes the locking rod to rotate clockwise around the hinge center of ear seat A. The torque generated by clockwise rotation is greater than the torque generated by counterclockwise rotation, causing the spring connected to the locking rod to be under tension under the action of the above two sets of torques. According to Hooke's Law, the spring also exerts a tensile force on the locking rod. The other end of the spring is connected to the support rod, and the spring also exerts a tensile force on the support rod. The support rod contacts the bottom surface of the tilting platform to ensure its static state. The force analysis of the locking rod on the other side is the same. The straightening roller is locked by the action of the two sets of locking rods. Then, the old roller ring on the straightening roller is removed and lifted away by the disassembly lifting device, and a new roller ring is installed. Then, the piston rods of the tail hydraulic cylinders located on both sides of the center line of the straightening roller are driven to extend, and the tilting platform rotates around the hinge center of the support seat on both sides of the center line of the straightening roller. The tilting platform rotates 90° from the vertical state to the horizontal state. Figure 1 As shown, the straightening roller is then supported by a lifting device. Once the support rods on both sides of the straightening roller's centerline are removed from the bottom surface and no longer in contact with the bottom surface of the tilting platform, the springs on both sides of the straightening roller's centerline return to their natural state. The locking rods on both sides of the straightening roller's centerline then rotate around their respective hinge centers to open the locking rods. The straightening roller is then lifted away by the lifting device, thus completing the entire tilting, locking, and opening process.

[0009] The device of the present invention can save a lot of time, improve production efficiency, reduce manual operation time, and is easy and simple to maintain. Attached Figure Description

[0017] The fixed base 5, located to the left of the center line of the roller ring storage rack, is fixed to the storage rack platform. Figure 2 As shown, two sets of support seats 7 located on both sides of the center line of the straightening roller are fixed to the fixed base 5. The tilting platform 8 is hinged to the two sets of support seats 7 on both sides. The tail of the tail swing shaft hydraulic cylinder 6 located on the left side of the center line of the straightening roller is hinged and fixed to the ear seat c on the fixed base 5. The flat head of the tail swing shaft hydraulic cylinder 6 located on the left side of the center line of the straightening roller is hinged and fixed to the ear seat E on the tilting platform 8. The tail of the tail swing shaft hydraulic cylinder 6 located on the right side of the center line of the straightening roller is hinged and fixed to the ear seat D on the fixed base 5. The flat head of the tail swing shaft hydraulic cylinder 6 located on the right side of the center line of the straightening roller is hinged and fixed to the ear seat F on the tilting platform 8. Figure 2 , 3 As shown in Figure 4.

[0018] The locking rod 4, located to the left of the center line of the straightening roller, is hinged and fixed to the lug A on the flipping platform 8. One end of the locking rod 4 on this side is connected to one end of the spring 2 on this side, and the other end of the spring 2 is connected to one end of the support rod 1 on this side. The other end of the locking rod 4 contacts the bottom surface (G surface) of the flipping platform 8. Figure 1 , 2 As shown in Figure 4, the locking rod 4 located to the right of the center line of the straightening roller is hinged and fixed to the lug B on the tilting platform 8. One end of the locking rod 4 on this side is connected to one end of the spring 2 on this side, and the other end of the spring 2 on this side is connected to one end of the support rod 1 on this side. The other end of the locking rod 4 on this side contacts the bottom surface of the tilting platform 8. Figure 1 , 2 As shown in Figure 4.

[0019] The support 3 located to the left of the center line of the straightening roller is fixed to the base 5, and the upper part of this side support 3 contacts the lower part of the side locking rod 4. The support 3 located to the right of the center line of the straightening roller is fixed to the base 5, and the upper part of this side support 3 contacts the lower part of the side locking rod 4. Figure 2 , 4 As shown.

[0020] Example 2

[0021] Based on the above embodiment, the entire flipping and locking process is as follows: First, the piston rods of the tail swing shaft hydraulic cylinders 6 located on both sides of the center line of the straightening roller are retracted. The flipping platform 8 rotates around the hinge center of the support seats 7 on both sides of the center line of the straightening roller. When the piston rods of the tail swing shaft hydraulic cylinders 6 located on both sides of the center line of the straightening roller are fully retracted, the flipping platform 8 flips 90° from the horizontal state to the vertical state. Figure 2As shown, one end of the locking rod 4 located on one side of the centerline of the straightening roller is engaged on a step on one side of the straightening roller. The locking rod 4 on this side is hinged to the ear seat A on this side. The lower part of the other end of the locking rod 4 on this side contacts the support 3 fixed on the fixed base 5 on this side, forming a seesaw structure. The end of the locking rod 4 on this side is connected to one end of the spring 2. The other end of the spring 2 is connected to the support rod 1 on this side. The support rod 1 on this side contacts the bottom surface of the flipping platform 8. One end of the locking rod 4 located on the other side of the centerline of the straightening roller is engaged on the other step of the straightening roller. On the step, the locking rod 4 on this side is hinged to the ear seat B on this side. The lower part of the other end of the locking rod 4 on this side contacts the support 3 fixed on the fixed base 5 on this side, forming a seesaw structure. The end of the locking rod 4 on this side is connected to one end of the spring 2, and the other end of the spring 2 is connected to the support rod 1 on this side. The support rod 1 on this side contacts the bottom surface of the flipping platform 8. Under the action of the locking rods 4 on both sides, the straightening roller is locked. The locking principle relies on the force principle of the seesaw. The principle is explained by the force analysis of the locking rod 4 on one side. Located at the center line of the straightening roller... The force exerted on the locking rod 4 by the head of the locking rod on the side relative to the step of the straightening roller causes the locking rod 4 to rotate counterclockwise around the hinge center of the ear seat A. The force exerted on the locking rod 4 by the support 3 on this side causes the locking rod 4 to rotate clockwise around the hinge center of the ear seat A. The torque generated by the clockwise rotation is greater than the torque generated by the counterclockwise rotation, causing the spring 2 connected to the locking rod 4 to be stretched under the action of the above two sets of torques. According to Hooke's Law, the spring 2 also exerts a tensile force on the locking rod 4. The other end of the spring 2 is connected to the support rod 1, and the spring 2 also exerts a tensile force on the support rod 1. The tensioning effect, through the contact between the support rod 1 and the bottom surface of the tilting platform 8, ensures the static state of the support rod 1. The force analysis of the locking rod 4 on the other side is the same as above. The straightening roller is locked by the action of the two sets of locking rods 4. Then, the old roller ring on the straightening roller is removed and lifted away by the disassembly lifting device and a new roller ring is installed. Then, the piston rods of the tail hydraulic cylinders located on both sides of the center line of the straightening roller are driven to extend, and the tilting platform 8 rotates around the hinge center of the support seat 7 on both sides of the center line of the straightening roller. The tilting platform 8 is tilted 90° from the vertical state to the horizontal state. Figure 1 As shown, the straightening roller is then supported by a lifting device. Once the support rods 1 located on both sides of the center line of the straightening roller are removed from the bottom surface and no longer in contact with the bottom surface of the flipping platform 8, the springs 2 located on both sides of the center line of the straightening roller return to their natural state. The locking rods 4 located on both sides of the center line of the straightening roller rotate around their respective hinge rotation centers to open the locking rods 4. Then, the straightening roller is lifted away by the lifting device. At this point, the entire flipping, locking and opening process is completed.
