Description

Technical Field

[0001] This application relates to the field of roller repair technology for steel enterprises, and in particular to a disassembly and assembly platform for frame rollers. Background Technology

[0002] In the field of mill stand roll repair technology in steel enterprises, mill stand rolls are the core equipment before and after the rolling mill. They are usually composed of three heavy-duty integrated rollers and adopt a gearbox centralized transmission mode. The bearing box and gearbox are an integral structure. The middle is set with a driving roller and the two sides are driven rollers. The idler teeth in the gearbox can transmit torque to realize the same rotation of the three rollers in the same direction and at the same speed. The gears, bearings and other components need to be disassembled and replaced regularly to maintain performance.

[0003] In existing technology, the repair and assembly of frame rollers involves a step-by-step operation using a simple platform and miscellaneous tools: First, all accessories inside the gearbox are assembled and placed on a 300mm high platform; then, a crane lifts the central main drive roller, aligns it with the installation position in the center of the gearbox, adjusts the idler teeth on both sides to fully mesh with the roller's drive teeth, and then uses a 5-ton chain hoist to pull the roller into place; finally, the driven rollers on both sides are installed using the same crane lifting and chain hoisting method. It should be noted that a single heavy-duty roller can weigh up to 7 tons, and the entire assembly process relies on the coordination of the crane and chain hoist.

[0004] However, the above-mentioned method for disassembling and assembling the frame rollers has several prominent problems: a single roller weighs up to 7 tons, and is prone to swaying or positional shifts during overhead crane hoisting. Even slight misalignment of personnel can cause crushing accidents, posing a serious safety hazard; furthermore, the separate step-by-step assembly of the three rollers makes it impossible to accurately control the gear meshing precision, which can easily lead to uneven stress on gears and bearings, resulting in damage such as component cracks, significantly shortening the service life of bearings and gears, and making it difficult to guarantee assembly quality; at the same time, the entire process requires frequent adjustments to the crane position and operation of the chain hoist, which requires high manual coordination and is labor-intensive. The repair and assembly of a single frame roller is time-consuming, seriously affecting equipment turnover and production progress. Utility Model Content

[0044] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application.

[0045] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0046] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0047] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0048] In the field of heavy-duty roller conveyor equipment maintenance, existing technologies for disassembling and assembling heavy-duty roller conveyors such as triple and double roller conveyors pose significant safety hazards and make it difficult to guarantee assembly quality. Traditional methods involve using overhead cranes to directly lift individual rollers weighing up to 7 tons for assembly, which carries the risk of personnel being crushed or injured in the process. Furthermore, assembling three rollers individually makes it difficult to ensure gear meshing precision, easily leading to uneven stress on gears and bearings, affecting equipment lifespan, and also resulting in high labor intensity and low work efficiency.

[0049] To address the aforementioned problems, this application provides a platform for disassembling and assembling frame rollers, see [link to relevant documentation]. Figures 1-8 It includes: platform frame 1, roller conveyor stop assembly 2, roller conveyor lifting assembly 4, and gantry frame 5.

[0050] Platform frame 1 is the load-bearing foundation and supporting body of the frame roller disassembly and assembly platform. It is a rectangular base structure welded from steel sections. Reinforcing beams are installed inside the base to enhance overall stability. Vertical columns are fixed on the top of the base, and the columns are connected by top crossbeams to form a rigid and stable working plane.

[0051] The roller conveyor stop assembly 2 is mounted on the top crossbeams on both sides of the platform frame 1 via a sliding connection, and its position can be adjusted according to the position of the frame roller 3. When the frame roller 3 is hoisted onto the work platform, its roller conveyor is placed on the roller conveyor stop assembly 2. At this time, the end face of the roller conveyor and the roller conveyor stop assembly 2 form a tight abutment, enabling the roller conveyor stop assembly 2 to reliably limit and fix the roller conveyor of the frame roller 3, effectively preventing accidental rolling or displacement of the heavy frame roller during disassembly and assembly operations. As the object to be repaired, the frame roller 3's roller conveyor is precisely positioned on the platform for subsequent disassembly and assembly operations. This avoids offset or shaking caused by external forces, providing a prerequisite for the precise assembly of the gearbox and bearings.

[0052] The roller conveyor lifting assembly 4 consists of a lifting support 41 and a support roller 42. The lifting support 41 is mounted on the base of the platform frame 1 via a sliding connection, and its sliding direction is consistent with the length direction of the top crossbeam of the platform frame 1. This arrangement allows the lifting support 41 to be adjusted along the roller conveyor axis according to actual needs, adapting to changes in roller spacing for different specifications of frame rollers.

[0053] The support roller 42 is rotatably mounted on top of the lifting support 41 via bearings. When the lifting support 41 is in the second position, the support roller 42 supports the bottom of the roller track of the frame roller 3, forming a rolling support. When the roller track rotates, it drives the support roller 42 to rotate synchronously. When the operator rotates the roller track with chain clamps, the follow-up rotation of the support roller 42 reduces the force required for operation, facilitates the adjustment of the meshing position during gear assembly, and ensures the alignment accuracy of the gear pair.

[0054] The roller conveyor lifting assembly 4 has a first position and a second position. In the first position, the top of the support roller 42 is lower than or flush with the top of the roller conveyor stop assembly 2. At this time, the roller conveyor of the frame roller 3 is supported by the platform frame 1 and axially positioned by the roller conveyor stop assembly 2. When height adjustment is required, the lifting support 41 can be driven by the jack to raise the support roller 42 to the second position. In the second position, the top of the support roller 42 is higher than the top of the roller conveyor stop assembly 2, smoothly lifting the roller conveyor of the frame roller 3 and freeing it from the constraint of the stop block 21. The operator can adjust the height of the frame roller 3 by controlling the lifting stroke of the jack, creating favorable conditions for subsequent bearing box or gearbox assembly operations.

[0055] The portal frame 5 is a separate component independent of the platform frame 1. Figure 1 and Figure 2 Not shown in the diagram. The gantry frame 5 is mounted across the frame roller 3 during use. The function of the gantry frame 5 is to provide a reliable fulcrum for applying force during the disassembly and assembly of the bearing housing and gearbox.

[0056] It should be noted that after hoisting the frame roller 3 onto the platform, the position of the roller conveyor stop assembly 2 is adjusted to ensure it is tightly abutted against the roller conveyor of the frame roller 3, thus completing the axial fixation. Subsequently, according to operational requirements, if the roller conveyor height needs to be adjusted, the jack is driven to change the roller conveyor lifting assembly 4 from the first position to the second position, lifting the roller conveyor. At this time, the roller conveyor height can be adjusted by controlling the stroke of the jack, and the rotation characteristics of the support roller 42, in conjunction with the chain clamp, are used to rotate the roller conveyor, achieving precise adjustment of the gear meshing position. When disassembling the bearing housing and gearbox, the gantry frame 5 is set up in the working area between the bearing seat cover and the roller conveyor eaves. By cooperating with auxiliary tools, a stable force transmission system is formed to complete the pressing or ejecting operation.

[0057] As can be seen from the above technical solution, the frame roller disassembly and assembly platform provided in this embodiment solves the technical difficulties in traditional frame roller repair operations through the coordinated cooperation of various functional components. The platform frame 1, as the basic load-bearing structure of the entire device, ensures overall stability during the disassembly and assembly of heavy-duty frame rollers through its rigid design. This structural characteristic fundamentally eliminates the risk of equipment displacement caused by unstable support, providing a reliable working foundation for subsequent precision operations. The sliding adjustment characteristic of the roller conveyor stop assembly 2 allows it to adapt to the positioning requirements of roller conveyors of different specifications. By precisely fixing both ends of the roller conveyor, this assembly effectively prevents accidental movement of the roller conveyor during operation, eliminating not only the safety hazards caused by this, but also providing a stable centering reference for precision assembly processes such as gear meshing. The design of the roller conveyor lifting assembly 4 enables controllable adjustment of the height of the frame roller 3. The rotating support structure of the support roller 42 significantly reduces the force required to rotate the heavy-duty frame roller, allowing operators to easily and accurately adjust the roller conveyor angle, thereby ensuring the optimal meshing state of the gear system. The gantry frame 5 provides a force fulcrum for the disassembly and assembly of the bearing housing. Its detachable design allows complex pressing operations to be carried out safely and systematically at fixed workstations, effectively replacing the dangerous operation methods of traditional processes that rely on overhead cranes and manual prying. This embodiment, through mechanical positioning and stable support, replaces manual handling and temporary fixing, significantly reducing the safety risks of personnel directly operating heavy components.

[0058] In some embodiments, see Figure 2 and Figure 5 The roller conveyor stop assembly 2 includes multiple pairs of opposing stop blocks 21. The stop blocks 21 are spaced apart along the length of the top crossbeam of the platform frame, with at least two stop blocks 21 on each roller conveyor, positioned near both ends of the conveyor. The stop blocks 21 are slidably connected to the top crossbeam of the platform frame via bolts. This sliding connection allows the stop blocks 21 to be adjusted along the length of the crossbeam to accommodate variations in roller spacing for different frame sizes. Inclined guide surfaces are machined on the opposing surfaces of the stop blocks 21 to ensure accurate positioning and stability of the roller conveyor during placement.

[0059] This embodiment replaces the manual handling operation in the traditional process with an adjustable mechanical positioning structure. The opposing stop blocks 21, with their adjustable position, can adapt to the positioning requirements of roller conveyors of different specifications, simultaneously constraining the roller conveyor from both sides to form a stable clamping state. This adjustable fixing method effectively prevents accidental rolling or displacement of the roller conveyor during operation, eliminating the safety risks of personnel directly contacting heavy-duty roller conveyors.

[0060] In some embodiments, see Figure 1 The roller conveyor lifting assembly 4 also includes a sliding base 43 and an L-shaped guide plate 44. The sliding base 43 is slidably mounted on the base of the platform frame 1. The L-shaped guide plate 44 is fixedly mounted on the sliding base 43 and extends in a direction perpendicular to the upper surface of the sliding base 43. The lifting support 41 and the L-shaped guide plate 44 form a sliding engagement, allowing the lifting support 41 to move up and down along the extension direction of the L-shaped guide plate 44. The L-shaped guide plate 44 provides a vertical movement trajectory for the lifting support 41, constrains the movement direction of the lifting support 41, prevents it from tilting during the lifting process, and ensures the stability and positioning accuracy of the lifting process.

[0061] In some embodiments, see Figure 1 An installation space for placing the first jack is formed between the bottom of the lifting support 41 and the upper surface of the sliding base 43. The depth of this space is determined according to the working stroke of the first jack to ensure sufficient operating margin during the lifting process. The structure around the space is reinforced to withstand the pressure generated during the lifting process. The first jack is placed in this space, its base is supported on the upper surface of the sliding base 43, and its piston rod end abuts against the bottom of the lifting support 41. At this time, the lifting force is directly transmitted through the bottom of the lifting support 41, driving the lifting support 41 to rise, thereby realizing the lifting movement of the roller conveyor lifting assembly 4.

[0062] In some embodiments, see Figure 4 , Figure 6 , Figure 8 and Figure 11The gantry frame 5 is the load-bearing component during dismantling operations. Positioned between the bearing housing cover and the roller conveyor eaves, the gantry frame 5 is designed as a portal frame spanning the roller conveyor. It features a three-hole design, equidistantly arranged laterally to accommodate the three rollers of the frame roller 3. The diameter of the holes is slightly larger than the outer diameter of the roller conveyor, ensuring both free passage for each roller and providing the necessary load-bearing area for the gantry frame 5. The space between the gantry frame 5 and the bearing housing accommodates the second jack. The dimensions of this space are adapted to the shape and working stroke of the second jack, ensuring its proper operation. When the second jack is placed in this space to perform the ejection operation, its base abuts against the gantry frame 5, and the end of its piston rod abuts against the bearing housing.

[0063] It should be noted that during operation, the gantry frame 5 is placed between the bearing housing and the roller conveyor eaves, with its three through holes corresponding to the three roller conveyors respectively. The second jacks are then sequentially placed into the space formed between the gantry frame 5 and the bearing housing. The base of the second jack abuts against the gantry frame 5, and the end of the piston rod of the second jack abuts against the bearing housing. When the ejection operation begins, all three second jacks are operated simultaneously. As the piston rods of the jacks extend, the ejection force pushes the bearing housing along the roller conveyor axis until the bearing housing is completely separated from the roller conveyor.

[0064] In some embodiments, see Figure 6 , Figure 9 , Figure 10 and Figure 11 The disassembly and assembly platform for the frame rollers also includes: tie rod 6 and crossbeam top rod 7. It should be noted that tie rod 6 and crossbeam top rod 7 are separate components independent of the platform frame 1. To clearly demonstrate the core structure of the platform, in Figure 1 and Figure 2 It is not shown in the text.

[0065] Tie rod 6 is a double-headed bolt structure used to connect the portal frame 5 and the crossbeam top rod 7. There are at least two tie rods 6, symmetrically arranged on both sides of the portal frame 5. The portal frame 5 has a first through hole, the diameter of which matches the diameter of the tie rod 6. The crossbeam top rod 7 has a second through hole, the diameter of which matches the diameter of the tie rod 6. The crossbeam top rod 7 is parallel to and opposite to the portal frame 5. One end of the tie rod 6 passes through the first through hole and is detachably connected to the portal frame 5. The other end of the tie rod 6 passes through the second through hole and is detachably connected to the crossbeam top rod 7. The portal frame 5, tie rod 6, and crossbeam top rod 7 can be assembled into a stable frame structure. A space for placing the third jack is formed between the crossbeam top rod 7 and the bearing seat. The dimensions of this space are designed according to the external dimensions of the third jack, and its depth must meet the working stroke requirements of the third jack.

[0066] It should be noted that, firstly, one end of the pull rod 6 is passed through the first through hole on the portal frame 5, and a nut is installed and tightened at that end. Then, the other end of the pull rod 6 is passed through the second through hole on the crossbeam top rod 7, and a nut is installed and tightened at that end. This connection method connects the portal frame 5 and the crossbeam top rod 7 into a single frame. During assembly, the third jack is placed in the space between the crossbeam top rod 7 and the bearing seat. The base of the third jack abuts against the crossbeam top rod 7, and the end of the piston rod of the third jack abuts against the bearing seat. When the third jack begins to work, as the piston rod extends, the jacking force presses the bearing into the bearing seat.

[0067] In some embodiments, see Figure 6 and Figure 12 The bearing housing support 8 serves to support and secure the bearing housing. By placing it directly on and in contact with the ground, it provides a stable and reliable support foundation. The top of the bearing housing support 8 features a support plane whose shape matches the bottom shape of the bearing housing, ensuring sufficient contact area and stability under load. This stable support prevents the bearing housing from tipping over during assembly. The reliable support structure avoids the safety risks caused by accidental movement of the bearing housing, creating a safe working environment for assembly operations.
