Description

Technical Field

[0001] The utility model relates to the field of disassembly and assembly of continuous casting rollers and couplings, in particular to a disassembly bracket of a continuous casting roller coupling. Background Art

[0002] The continuous casting roller is a roller installed in the secondary cooling section. Due to the static pressure of the molten steel inside the ingot at the secondary cooling position and the thermal stress of cooling, it deforms and easily causes surface slip. Therefore, a cooling clamp is installed in the secondary cooling section as a guiding mechanism.

[0003] In the prior art, since the billet is clamped between two rows of rollers for solidification, straightening and drawing, the rollers, while in contact with the high-temperature billet, are also subjected to rapid cooling by high-pressure cooling water, and are constantly subjected to heating and cooling. The service life of the rollers working in such harsh environments is short. The reasons are as follows:

[0004] 1. Repeated heating and cooling will cause cracks on the roller surface. As the cracks expand and extend, they will eventually become scrapped.

[0005] 2. The roller surface is in contact with the high-temperature billet and is eroded by high-temperature oxidation and cooling water, causing oxidation and corrosion peeling, forming uneven defects, which seriously affect the surface quality of the billet and make it unusable;

[0006] Therefore, it is necessary to dismantle and replace the damaged continuous casting roller by disassembling the coupling. In the prior art, due to the production tolerance of the No. 2 docking shaft at both ends of the continuous casting roller, it is inconvenient to dock the No. 1 docking shaft and the No. 2 docking shaft when the coupling is docked during the installation process. Utility Model Content

[0007] The purpose of the utility model is to provide a disassembly bracket for a continuous casting roller coupling in order to solve the problems raised in the above background technology.

[0009] The rotating shaft passes through the supporting frame, and a circular hole for the rotating shaft to move is provided at a position where the supporting frame contacts the rotating shaft.

[0010] As a further solution of the present invention: the coupling mechanism includes a No. 1 docking shaft integrally formed at one end of the rotating shaft and a No. 2 docking shaft integrally formed at both ends of the continuous casting roller, a fixed disk is welded to the outer wall of the No. 1 docking shaft, a lower coupling is integrally formed at the bottom of one end of the fixed disk, and the top end of the lower coupling is detachably connected to the upper coupling.

[0011] As a further solution of the present invention: the synchronous drive mechanism includes a synchronous shaft rotatably installed in the inner cavity of the base plate, and a gear is interference-fitted on the middle section of the outer wall of the synchronous shaft. Racks are meshed above and below the outer wall of the gear, and the ends of the two racks away from each other penetrate to the outside of the base plate and are fixedly connected to the bottom end of the connecting frame.

[0012] As a further solution of the present invention: the synchronous drive mechanism also includes a forward and reverse motor installed on one end of the base plate through a fixing frame, and the output shaft of the forward and reverse motor passes through the interior of the support frame and is coaxially fixed to one end of the synchronous shaft.

[0013] As a further solution of the present invention: the bottom and top of the inner wall of the support frame are integrally formed with a limiting slide, and sliding grooves that are slidably connected to the cross-plate portion of the limiting slide are opened on both sides of the rack, and the cross-plate portion of the limiting slide is slidably connected to the sliding grooves.

[0014] As a further solution of the present invention: strip grooves for the rack to slide out are opened at both ends of the bottom plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. By setting up a synchronous drive mechanism and a coupling mechanism, the second docking shaft with production tolerances can be installed and fixed more conveniently, thereby improving the installation or disassembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In this embodiment, when the continuous casting roller 4 is installed and fixed, the synchronous driving mechanism is started, which drives the two connecting frames 7 to move toward or in opposite directions. The two connecting frames 7 that move toward or in opposite directions respectively drive the two rotating shafts 6 to move toward or in opposite directions. The two rotating shafts 6 that move toward or in opposite directions can drive the two sets of coupling mechanisms to move toward or in opposite directions synchronously, thereby forming support for the two ends of the continuous casting roller 4. Then, the two ends of the continuous casting roller 4 are fixed by the coupling mechanisms.

[0026] When disassembling the continuous casting roller 4, first, the two sets of coupling mechanisms are disassembled, and then the continuous casting roller 4 can be pulled upward to be disassembled.

The top of the lower coupling 9 is detachably connected to the upper coupling 10.

[0028] In this embodiment: when the two rotating shafts 6 move toward or oppositely, the two moving rotating shafts 6 can drive the inner No. 1 docking shaft 8 to move synchronously, the No. 1 docking shaft 8 drives the fixed disk 12 to move synchronously, and the fixed disk 12 can drive the lower coupling 9 to move, and the two lower couplings 9 move toward or oppositely until the two lower couplings 9 can form support under the No. 2 docking shaft 11 at both ends of the continuous casting roller 4, and then use bolts and nuts to install and fix the upper coupling 10 and the lower coupling 9, so that the continuous casting rollers 4 of different lengths can be fixed.

The output shaft of the forward and reverse motor 3 passes through the interior of the support frame 1 and is coaxially fixedly connected to one end of the synchronous shaft 16.

[0030] In this embodiment: the forward and reverse motors 3 are started synchronously, and the operation of the forward and reverse motors 3 drives the synchronization shaft 16 to rotate, and the synchronization shaft 16 can drive the gear 15 to rotate forward or reverse. At this time, the two racks 13 distributed above and below slide toward or oppositely, and the two racks 13 can move synchronously by driving the connecting frame 7 installed at their ends, and the moving connecting frame 7 can drive the rotating shaft 6 to move synchronously.

[0033] Please refer to Figure 1 , strip grooves 5 for the rack 13 to slide out are provided at both ends of the bottom plate 2.
