Description

Technical Field

[0001] The present application relates to the technical field of auxiliary devices for continuous casting equipment, and in particular to a convenient disassembly tool for continuous casting rollers. Background Art

[0002] The continuous casting roller is the most critical component of the continuous casting machine. It is responsible for bearing the weight, driving the steel billet and the movable billet mold. It is extremely intensive to use. Long-term use will cause varying degrees of damage to the continuous casting roller.

[0003] The continuous casting roller is very difficult to disassemble due to the influence of scale, rust and deformation. The existing operation method is to use the impact force of the inertia hammer to drive the roller sleeve to move outwards when disassembling the roller to remove the parts. Figure 1 As shown, the side of the continuous casting roller that moves is pulled downward by gravity, causing the end of the roller's core shaft still inside the bearing seat to fit tightly against the inner hole of the bearing seat, making disassembly more difficult. If disassembly is impossible, a gas torch is used to cut away the external connecting parts, such as the bearing seat or bearings, before proceeding. This labor-intensive and inefficient process also results in deformation, damage, and even scrapping of the workpiece due to violent and destructive disassembly. This increases the difficulty of repair, increases costs, and is inconvenient. Utility Model Content

[0026] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.

[0027] The embodiment of the present application provides a convenient continuous casting roller disassembly tool, comprising a support body 10, a movable groove 11 in the middle of the support body 10, the movable groove 11 having space for component movement, a fixing bar 20 provided on the top outer side of the support body 10, the fixing bar 20 having a plurality of through holes 21 arranged linearly, the axis of the fixing bar 20 being parallel to the axis of the support body 10, and the line connecting the centers of the top openings of the plurality of through holes 21 distributed on the fixing bar 20 being parallel to the axis of the fixing bar 20;

[0028] The movable groove 11 is provided with a bearing assembly 30 for supporting the continuous casting roller and a top plate assembly 40 for supporting the bearing seat. The top plate assembly 40 is located at one end of the movable groove 11. The bearing assembly 30 can slide in the movable groove 11 and is located on one side of the top plate assembly 40.

[0029] A fixed hydraulic mechanism 50 can be set on the side of the top plate assembly 40 away from the bearing assembly 30. The telescopic rod of the hydraulic mechanism 50 extends out to push the continuous casting roller in the bearing seat, so that the continuous casting roller is separated from the bearing seat in the direction away from the hydraulic mechanism 50. When the continuous casting roller moves, the bearing assembly 30 carries the continuous casting roller to move in a directional manner in the movable groove 11.

[0030] The following is a further introduction based on specific usage scenarios.

[0031] During use, the operator places the bearing seat in the continuous casting roller assembly on the top plate assembly 40, and aligns the mounting hole on one side of the bearing seat with the multiple through holes 21 on the fixing bar 20. The continuous casting roller installed on the bearing seat is supported by the supporting assembly 30 so that the central axis of the continuous casting roller and the bearing hole of the bearing seat are always in a parallel state.

[0032] When disassembling the bearing seat and the continuous casting roller, the operator starts the hydraulic mechanism 50, so that the telescopic rod of the hydraulic mechanism 50 pushes the end of the continuous casting roller in the bearing seat, so that the continuous casting roller is separated from the bearing seat in the direction away from the hydraulic mechanism 50. The end of the continuous casting roller away from the bearing seat is supported by the bearing assembly 30, and the end of the continuous casting roller away from the bearing seat does not deviate downward. In this way, the part of the continuous casting roller located in the inner hole of the bearing seat will not be in close contact with the top of the inner hole of the bearing seat. In this way, the friction between the continuous casting roller and the inner hole of the bearing seat is reduced, and the degree of interference between the continuous casting roller and the inner hole of the bearing seat due to the gravity offset of one end is reduced. The operator does not need to support the end of the continuous casting roller away from the bearing seat, which significantly reduces the labor intensity of the operator, significantly reduces the time required for the operator to disassemble the continuous casting roller, and significantly improves the overall efficiency of the continuous casting roller disassembly process.

[0033] During disassembly, as the continuous casting roller moves, the bearing assembly 30 used to support the continuous casting roller will move in a directional manner in the movable groove 11 to ensure the relative position of the continuous casting roller, maintain the angular relationship between the center axis of the continuous casting roller and the center axis of the inner hole of the bearing seat, and reduce the degree of interference between the continuous casting roller and the inner hole of the bearing seat due to the gravity offset of one end.

[0034] In general, the embodiment of the present application maintains the relative angular relationship between the center axis of the continuous casting roller and the center axis of the inner hole of the bearing seat by using the support body 10 and the load-bearing assembly 30 to support the bearing seat and the continuous casting roller respectively, thereby reducing the degree of interference between the continuous casting roller and the inner hole of the bearing seat due to the gravity offset of one end, reducing the friction between the continuous casting roller and the inner hole of the bearing seat, and eliminating the need for the operator to support the end of the continuous casting roller away from the bearing seat, thereby significantly reducing the labor intensity of the operator and significantly improving the overall efficiency of the continuous casting roller disassembly process.

[0035] The bearing assembly 30 is used to support the exposed part of the continuous casting roller, so that during the disassembly process, the bottom of the exposed part of the continuous casting roller away from the bearing seat is always supported, maintaining the relative angle relationship between the center axis of the continuous casting roller and the center axis of the inner hole of the bearing seat within an acceptable range, and avoiding the part of the continuous casting roller in the inner hole of the bearing seat from being close to the upper wall of the inner hole. In a feasible implementation method of the embodiment of the present application, the bearing assembly 30 includes a support member 31 for supporting the roller body of the continuous casting roller, and a connecting member 32 is provided at the bottom of the support member 31. The bottom of the connecting member 32 is rotatably connected to a rolling shaft 33, and rollers 34 are installed at both ends of the rolling shaft 33. In actual use, the support member 31 supports the continuous casting roller, and the roller 34 at the bottom is used for directional sliding in the movable groove 11.

[0036] In order to better maintain the relative position of the continuous casting roller, the support member 31 in the embodiment of the present application includes a U-shaped block 35, and the top of the U-shaped block 35 has a groove 36 that is recessed toward the bottom of the movable groove 11, and the opening of the groove 36 faces the top of the movable groove 11. After the continuous casting roller is placed on the U-shaped block 35, since the top of the U-shaped block 35 has the groove 36, the cylindrical continuous casting roller is stuck in the groove 36 due to gravity, which further improves the stability of the position of the continuous casting roller during the disassembly process, reduces the degree of interference between the continuous casting roller and the inner hole of the bearing seat due to the gravity offset at one end, reduces the friction between the continuous casting roller and the inner hole of the bearing seat, and significantly improves the overall efficiency of the continuous casting roller disassembly process.

[0037] The bearing assembly 30 can slide in a directional manner inside the movable groove 11 so that the angle between the central axis of the continuous casting roller and the central axis of the inner hole of the bearing seat is always within a certain range during the disassembly process, thereby reducing the degree of interference between the continuous casting roller and the inner hole of the bearing seat due to the gravity offset of one end. In a feasible implementation method of the embodiment of the present application, a slide rail 12 is provided at the bottom of the movable groove 11 to limit the movement path of the bearing assembly 30. The central axis of the slide rail 12 is parallel to the central axis of the movable groove 11. The movement path of the bearing assembly 30 is limited by the guide rail to further improve the stability of the position of the continuous casting roller during the disassembly process. The slide rail 12 can have two, and the two ends of the rolling shaft 33 are respectively connected to the two slide rails 12 in a rolling manner.

[0038] In some possible implementations of the embodiments of the present application, there are two bearing assemblies 30, which are used to support the roller sleeve and core shaft of the continuous casting roller respectively. The inner surfaces of the grooves 36 of the U-shaped blocks 35 at the top of the two bearing assemblies 30 do not belong to the same plane. In this way, when the operator completely disassembles the continuous casting roller assembly, the two bearing assemblies 30 can support the shaft sleeve and core shaft of the continuous casting roller respectively, so that the angular relationship between the shaft sleeve, core shaft and the central axis of the inner hole of the bearing seat of the continuous casting roller is always within a certain range, reducing the degree of interference between the continuous casting roller and other components due to the gravity offset at one end.

[0039] In some possible implementations of the embodiments of the present application, there are two fixing bars 20, which are respectively fixed to the two sides of the top of the support body 10. The top plane of the fixing bar 20 is coplanar with the top plane of the support body 10, so that the bearing seat can be more stable when fixed.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
