Description

Technical Field

[0001] This invention relates to the field of lifting and moving technology, specifically a moving device for the main roller reducer of a ring rolling mill. Background Technology

[0002] The main roll reducer of the horizontal CNC radial and axial ring rolling mill is the core component of the equipment's power transmission system. Its core function is to precisely convert the high-speed rotational power output by the main motor into the low-speed, high-torque power required for the rolling operation through multi-stage gear transmission. This drives the ring to complete the precision rolling process simultaneously in the radial and axial directions. The reducer is usually integrated into the horizontal machine body and deeply linked with the CNC system. It can respond to rolling parameter adjustments in real time and achieve high-precision control of the ring wall thickness, diameter, and cross-sectional profile. It is especially suitable for the efficient forming of large and complex seamless rings such as wind turbine bearing rings, nuclear power flanges, and large gear rings. It is an indispensable key process equipment in the field of high-end equipment manufacturing.

[0003] However, this core component faces insurmountable maintenance challenges in actual operation and maintenance: the main roll reducer, which needs to bear the huge torque of heavy rolling, often weighs tens of tons. The civil engineering foundation of the horizontal radial axial rolling mill generally adopts a U-shaped closed structure. Although this design can enhance the overall stability of the equipment, it tightly surrounds the main roll reducer in the internal space, making it impossible to carry it out for maintenance by vertical lifting. According to the maintenance procedure, the reducer, which weighs tens of tons, must first be moved horizontally to the preset lifting port before being lifted out.

[0004] However, traditional main roll reducers lack corresponding movable devices and are not equipped with dedicated movable support devices. This makes it difficult to lift and transport the main roll reducers, hindering maintenance and thus delaying production. Furthermore, designing movable devices for main roll reducers presents the challenge of adapting to variations in machine specifications. Different models of horizontal CNC radial axial ring rolling mills have different maximum diameters, cross-sectional complexities, and rolling force requirements for the rolled rings, resulting in significant differences in the external dimensions of the matched main roll reducers. This necessitates that the movable device possess high flexibility and compatibility, precisely adapting to the installation and positioning requirements of different reducer specifications. Therefore, achieving perfect compatibility between the movable device and the main roll reducer becomes the core key to improving equipment operation and maintenance efficiency. Summary of the Invention

A moving component is provided at the bottom of the mounting plate. The moving component is used to assist the main roller reducer body in moving.

[0008] Furthermore, a first spring is fixedly connected between the other end of the first support rod and the corresponding first connecting frame; a second spring is fixedly connected between the other end of the second support rod and the corresponding second connecting frame.

[0009] Furthermore, the drive block has a parallelogram structure. The two opposite ends of the drive block are provided with a first connecting seat, and the other two opposite ends of the drive block are provided with a second connecting seat. The first support rod and the second support rod are respectively fixedly connected to the first shaft platform and the second shaft platform at one end of the first support rod extending into the mounting frame. The adjacent first connecting seat and the first shaft platform are rotatably connected by a first connecting rod, and the adjacent second connecting seat and the second shaft platform are rotatably connected by a second connecting rod.

[0010] Furthermore, an arc-shaped groove is provided on the outer wall of the mounting frame, and a mounting shaft is fixedly connected to the drive block. The mounting shaft is movably connected in the arc-shaped groove. A second hydraulic cylinder is provided on the outer wall of the mounting frame. A ring frame is fixedly connected to the end of the second hydraulic cylinder, and the ring frame is rotatably connected to the mounting frame. A second connecting ring is fixedly connected to the output end of the second hydraulic cylinder, and the second connecting ring is rotatably connected to the mounting shaft.

[0011] Furthermore, the distance between the first connecting seat and the center of the drive block is greater than the distance between the second connecting seat and the center of the drive block, and the length of the first link is greater than the length of the second link.

[0012] Furthermore, the movable component includes a rotating frame, a mounting base, and rollers symmetrically arranged on the mounting base; a support base is fixedly connected to the bottom of the mounting plate, the rotating frame is rotatably connected to the support base, the mounting base is fixedly connected to the rotating frame, and the rollers are rotatably connected to the mounting base.

[0013] Furthermore, limit blocks are installed on the rotating frame.

[0014] Furthermore, a connecting shaft is fixedly connected to the mounting base, and a first hydraulic cylinder is provided between the connecting shaft and the mounting plate. A first connecting ring is fixedly connected to the output end of the first hydraulic cylinder, and the first connecting ring is rotatably connected to the connecting shaft.

[0015] Furthermore, the end of the first hydraulic cylinder is symmetrically and fixedly connected with trunnions, and the bottom of the mounting plate is fixedly connected with a bearing seat, and the trunnions and the bearing seat are rotatably connected.

[0016] Furthermore, it also includes a U-shaped foundation with a hoisting opening. The main roller reducer body is located inside the U-shaped foundation. Two steel plates are placed below the main roller reducer body, and a pulley seat is provided between the two steel plates. A fixed pulley is rotatably connected to the pulley seat. The fixed pulley is located below the hoisting opening, and the steel wire rope is provided between the main roller reducer body and the fixed pulley.

[0017] The beneficial effects of this invention compared to the prior art are as follows:

[0018] 1. This invention constructs an efficient lateral translation and lifting system by setting up two steel plates, pulley seats, fixed pulleys, wire ropes, and rolling wheels in the moving components below the main roller reducer body, combined with the hoisting port on the U-shaped foundation. When maintenance is required, the main roller reducer body, weighing tens of tons, can be smoothly moved laterally along the steel plates to directly above the hoisting port by using the cooperation of the wire rope and the fixed pulley. This solves the problem that the U-shaped closed civil engineering foundation cannot be directly lifted vertically, creating the necessary conditions for subsequent lifting and removal.

[0019] 2. This invention cleverly addresses the compatibility issue of main roller reducers of different specifications through a support frame. Driven by a second hydraulic cylinder, the drive block within the mounting frame slides within the mounting frame via a first connecting rod and a second connecting rod, respectively. This causes the first connecting frame and the second connecting frame to push the L-shaped frame to move via a first fixed rod and a second fixed rod. The positioning plate on the L-shaped frame can be adjusted according to the reducer's dimensions. With the help of the tension of the first and second springs, the distance between the L-shaped frame and the mounting frame can be finely adjusted, ensuring that the positioning plate is tightly attached to the base plate at the bottom of the main roller reducer body. This ensures that main roller reducers of different specifications can be stably and accurately supported and positioned, achieving a high degree of flexibility and compatibility of the device.

[0020] 3. This invention further enhances the convenience and stability of movement through the movable component at the bottom of the mounting plate. The first hydraulic cylinder drives the rotating frame to rotate on the support base via a connecting shaft, thereby driving the mounting base and rolling wheels to adjust their angles. When movement is required, the rolling wheels contact the ground to assist the main roller reducer body in movement; when reaching the designated position or needing to be fixed, the rolling wheels can be retracted via the first hydraulic cylinder to secure the device. At the same time, the limiting block can limit the rotation angle of the mounting base, preventing rotation beyond 90 degrees and avoiding structural instability caused by excessive rotation, thus ensuring the safety and reliability of the movement process. This multi-component collaborative design not only achieves convenient movement and precise positioning of the main roller reducer but also significantly improves equipment maintenance efficiency, avoiding production delays due to the inability to perform maintenance.

Detailed Implementation

[0032] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solutions of this invention are described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0033] Please see Figures 1 to 9This invention provides a mobile device for the main roller reducer of a ring rolling mill, including a main roller reducer body 1 and a molded foundation 7. A hoisting opening 701 is provided on the molded foundation 7. The main roller reducer body 1 is located within the molded foundation 7. Two steel plates 2 are placed below the main roller reducer body 1, and a pulley seat 3 is provided between the two steel plates 2. A fixed pulley 4 is rotatably connected to the pulley seat 3, and the fixed pulley 4 is located below the hoisting opening 701. A steel wire rope 5 is provided between the main roller reducer body 1 and the fixed pulley 4. Through the combination of the molded foundation 7, the hoisting opening 701, the steel plates 2, the fixed pulley 4, and the steel wire rope 5, the main roller reducer body 1 can be quickly converted from a fixed support state to a movable state, solving the problem that the molded closed foundation cannot be directly lifted vertically. A support frame 6 is provided below the main roller reducer body 1. The support frame 6 is used to adapt to the main roller reducer body 1 of different specifications. The support frame 6 includes a mounting frame 601, a drive block 613, multiple L-shaped frames 608, and first support rods 602 and second support rods 605, which are symmetrically arranged. A mounting plate 18 is fixedly connected to the L-shaped frame 608. A moving component is provided at the bottom of the mounting plate 18. The moving component is used to assist the main roller reducer body 1 in moving. The moving component includes a rotating frame 9, a mounting seat 11, a limiting block 10, and rolling wheels 12 symmetrically arranged on the mounting seat 11. The support frame 6 adopts a symmetrical multi-rod support structure, which is uniformly stressed and has stable load-bearing capacity. It can be adapted to the bottom base plate of the reducer with different length and width dimensions, and has strong versatility. The moving component adopts an unfoldable and retractable structure, which does not occupy the normal working space of the equipment, and at the same time has multiple functions of support, steering, and translation.

[0034] like Figure 7 and Figure 8As shown, the mounting bracket 601 has a cross-shaped structure. One end of each of the two first support rods 602 and one end of each of the two second support rods 605 are slidably connected to the mounting bracket 601, with the two first support rods 602 and the two second support rods 605 positioned opposite each other. The other end of each of the two first support rods 602 is slidably connected to a first connecting bracket 603, and a first spring 611 is fixedly connected between the other end of each first support rod 602 and the corresponding first connecting bracket 603. The other end of each of the two second support rods 605 is slidably connected to a second connecting bracket 606, and a second spring 612 is fixedly connected between the other end of each second support rod 605 and the corresponding second connecting bracket 606. The cross-shaped mounting bracket 601 has high structural rigidity and precise guidance, ensuring the first support rod... The strut 602 and the second support rod 605 slide smoothly without jamming; the first spring 611 and the second spring 612 provide adaptive tension to achieve flexible contact between the positioning plate 610 and the reducer base plate, avoiding deformation caused by rigid impact. The first connecting frame 603 is symmetrically fixedly connected to the two sides of the first fixing rod 604, and the second connecting frame 606 is symmetrically fixedly connected to the two sides of the second fixing rod 607. The ends of adjacent first fixing rods 604 and second fixing rods 607 are slidably connected to the same L-shaped frame 608. The positioning plate 610 is fixedly connected to the L-shaped frame 608. The first fixing rod 604 and the second fixing rod 607 adopt a sliding fit, so that the L-shaped frame 608 can be adjusted synchronously with the support size, ensuring synchronous action of multi-point support and good positioning consistency.

[0035] like Figure 9As shown, the drive block 613 is rotatably connected within the mounting bracket 601. The drive block 613 has a parallelogram structure. The parallelogram drive block 613, together with the first connecting rod 614 and the second connecting rod 615, forms a synchronous drive mechanism. A single power drive can realize the synchronous movement of the multi-directional support rods, resulting in high adjustment efficiency. One set of opposite ends of the drive block 613 is provided with a first connecting seat 619, and the other set of opposite ends is provided with a second connecting seat 621. The first support rod 602 and the second support rod 605 are respectively fixedly connected to the first shaft platform 618 and the second shaft platform 620 at one end of the first support rod 602 and the second support rod 605 extending into the mounting bracket 601. The first connecting rod 614 is rotatably connected between the adjacent first connecting seat 619 and the first shaft platform 618, and the second connecting rod 615 is rotatably connected between the adjacent second connecting seat 621 and the second shaft platform 620. An arc-shaped groove is provided on the outer wall of the mounting bracket 601. A mounting shaft 617 is fixedly connected and movably connected within an arc-shaped groove. The arc-shaped groove provides a limiting guide for the mounting shaft 617, preventing excessive rotation of the drive block 613 and potential jamming of the mechanism. A second hydraulic cylinder 609 is mounted on the outer wall of the mounting frame 601. A ring frame 622 is fixedly connected to the end of the second hydraulic cylinder 609 and rotatably connected to the mounting frame 601. A second connecting ring 616 is fixedly connected to the output end of the second hydraulic cylinder 609 and rotatably connected to the mounting shaft 617. The first connecting seat 619 and the second connecting seat 621 have different center distances and different connecting rod lengths, resulting in different adjustment ranges in the length and width directions of the support frame 6, better matching the proportionally scaled shape of the reducer. The second hydraulic cylinder 609 is floatingly mounted via the ring frame 622, adapting to angle changes during the driving process, ensuring smooth and reliable operation.

[0036] like Figure 5 and Figure 6As shown, a support base 8 is fixedly connected to the bottom of the mounting plate 18, and a rotating frame 9 is rotatably connected to the support base 8. A limit block 10 is provided on the rotating frame 9. The support base 8 and the rotating frame 9 form a hinged support structure, which is flexible in rotation and has a strong load-bearing capacity, capable of withstanding tens of tons of vertical load. The limit block 10 limits the rotation angle to within 90° to prevent the rolling wheel 12 from overturning due to excessive deflection. The mounting base 11 is fixedly connected to the rotating frame 9, and the rolling wheel 12 is rotatably connected to the mounting base 11. A connecting shaft 13 is fixedly connected to the mounting base 11. A first hydraulic cylinder 14 is provided between the connecting shaft 13 and the mounting plate 18. The first hydraulic cylinder 14 is arranged with hinges at both ends, and the thrust output is stable, which can realize the smooth unfolding and retraction of the rolling wheel 12. The trunnion 16 cooperates with the bearing 17 to counteract the angular displacement during the extension and retraction of the hydraulic cylinder, ensuring... The mechanism operates smoothly without jamming. The output end of the first hydraulic cylinder 14 is fixedly connected to the first connecting ring 15, and the first connecting ring 15 is rotatably connected to the connecting shaft 13. The end of the first hydraulic cylinder 14 is symmetrically fixedly connected to the trunnion 16. The bottom of the mounting plate 18 is fixedly connected to the bearing seat 17, and the trunnion 16 is rotatably connected to the bearing seat 17. The rolling wheels 12 are symmetrically arranged, and the support points are evenly distributed. During the movement, the reducer body is stable and does not tilt. The retracted state of the rolling wheels 12 can significantly reduce the height of the device, without interfering with the normal production operation of the ring rolling machine, and without changing the original installation space and layout of the equipment. The steel plate 2 increases the ground bearing area, reduces pressure, and avoids the heavy reducer damaging the foundation ground. The fixed pulley 4 realizes a 90° change in the direction of the pulling force, and the heavy reducer can be moved with a small traction force, making the operation labor-saving, safe and efficient.

[0037] This device is mainly used to solve the problems of not being able to directly lift the main roller reducer of a horizontal ring rolling mill vertically within a U-shaped enclosed foundation, and the difficulty in universally adapting reducers of different specifications. The overall working process is divided into four continuous stages: self-adaptive positioning support, deployment of moving components, lateral translation and displacement, lifting and resetting. All components work together to achieve safe, stable, and efficient movement and maintenance of heavy-duty reducers. The specific working principle is as follows:

[0038] During the adaptive positioning support stage, the device automatically clamps and positions the main roller reducer body 1 of different specifications through the support frame 6, and starts the second hydraulic cylinder 609 installed on the outside of the mounting frame 601. The output end of the second hydraulic cylinder 609 drives the mounting shaft 617 on the drive block 613 through the second connecting ring 616, so that the mounting shaft 617 moves in a circular motion along the arc groove on the outer wall of the mounting frame 601, thereby driving the parallelogram structure drive block 613 to rotate inside the cross-shaped mounting frame 601.

[0039] When the drive block 613 rotates, the first connecting seat 619 and the second connecting seat 621 at its ends drive the first axle 618 at the end of the first support rod 602 and the second axle 620 at the end of the second support rod 605 to move through the first connecting rod 614 and the second connecting rod 615 respectively, so that the two first support rods 602 and the two second support rods 605 slide outward synchronously along the guide structure of the mounting frame 601.

[0040] The first support rod 602 drives the first connecting frame 603 and the first fixed rod 604 to move synchronously, and the second support rod 605 drives the second connecting frame 606 and the second fixed rod 607 to move synchronously, thereby pushing multiple sets of L-shaped frames 608 to retract towards the bottom of the main roller reducer body 1. During this process, the first spring 611 between the first connecting frame 603 and the first support rod 602, and the second spring 612 between the second connecting frame 606 and the second support rod 605, can adaptively extend and retract according to the actual size of the reducer bottom base plate, and precisely finely adjust the position of the L-shaped frame 608. Finally, the positioning plate 610 on the L-shaped frame 608 is completely in close contact with the bottom base plate of the main roller reducer body 1, realizing stable, reliable, and gapless support for the main roller reducer body 1 of different shapes and sizes, ensuring that the reducer does not deviate or shake during movement.

[0041] During the deployment phase of the mobile component, the device switches from a supported state to a movable state. First, an external jack is used to lift the main roller reducer body 1 as a whole to provide space for the deployment of the mobile component. Then, the first hydraulic cylinder 14 at the bottom of the mounting plate 18 is activated. The cylinder end of the first hydraulic cylinder 14 is hinged to the bearing seat 17 through the trunnion 16. Its output end pushes the connecting shaft 13 on the mounting seat 11 through the first connecting ring 15, so that the rotating frame 9 rotates downward around the support seat 8. The limiting block 10 set on the rotating frame 9 can limit the maximum rotation angle of the mounting seat 11 to no more than 90°, so as to avoid uneven force on the rolling wheel 12 or structural instability due to excessive rotation.

[0042] When the mounting base 11 is rotated to the set position, the rolling wheels 12 symmetrically arranged on the mounting base 11 are fully extended and come into contact with the steel plate 2 below. At this time, the jack is slowly retracted, so that the main roller reducer body 1 and the support frame 6 fall smoothly onto the steel plate 2. The rolling wheels 12 bear the main support load, and the device is converted from the fixed support mode to the movable mode, which is ready for subsequent lateral translation.

[0043] During the lateral translation and relocation stage, the device enables the main roller reducer body 1 to move horizontally within the shaped foundation 7. With the shaped foundation 7 as a fixed support, the pulley seat 3 is fixed at a designated position below the hoisting port 701. The fixed pulley 4 maintains a stable position along with the pulley seat 3. One end of the wire rope 5 is fixedly connected to the main roller reducer body 1, and the other end passes around the fixed pulley 4 to form a tension reversal structure. By pulling the wire rope 5 through external traction equipment or manually, the fixed pulley 4 converts the vertical tension into a horizontal traction force. With the assistance of the rolling wheel 12, the main roller reducer body 1 moves smoothly and horizontally along the surface of the two steel plates 2 until it is precisely pulled to a position directly above the hoisting port 701 on the shaped foundation 7. During this process, the rolling wheel 12 can effectively reduce the movement resistance, and the support frame 6 continuously maintains stable support for the reducer, ensuring that the main roller reducer body 1, weighing tens of tons, is stable, without jamming or tilting during the translation process.

[0044] During the lifting, removal, and repositioning phase, the device completes the lifting and reinstallation of the reducer. When the main roller reducer body 1 reaches directly above the lifting port 701, the wire rope 5 is kept connected to the main roller reducer body 1. The wire rope 5 is then disconnected from the fixed pulley 4 and directly connected to the hook of the lifting equipment. The lifting equipment provides a vertically upward lifting force to vertically lift the main roller reducer body 1 from the lifting port 701, allowing for inspection, maintenance, or replacement work to be carried out.

[0045] After the overhaul is completed, the operation is carried out in reverse order: first, the main roller reducer body 1 is hoisted back to above the hoisting port 701 and lowered back onto the steel plate 2. Then, the steel wire rope 5 and the fixed pulley 4 are used to move it back to its original working position. Finally, the first hydraulic cylinder 14 is activated to retract the rolling wheel 12, and the second hydraulic cylinder 609 is activated to release the clamping and positioning of the support frame 6. The auxiliary components such as the steel plate 2, pulley seat 3 and fixed pulley 4 are removed, and the device is restored to its initial state. The main roller reducer body 1 can be put back into use.
