Detailed Description
For a clearer understanding of technical features, objects, and effects of the present invention, a specific embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in fig. 1 to 4, the present invention provides a mounting guide structure 100 for an electromagnetic stirring device at the end of a continuous casting machine, comprising a plurality of guide rails 1 arranged at intervals, the guide rails 1 are arranged at both sides of a fixed section 90 at the end of the continuous casting machine in pairs, and the top ends of the guide rails 1 are provided with guide rail openings; a pull rod structure 2 is arranged between two adjacent guide rails 1 positioned on the same side of the continuous casting machine tail end fixing section 90, and each pull rod structure 2 is detachably connected with a heat preservation cover 91 of the continuous casting machine tail end fixing section; the installation guiding structure 100 of the electromagnetic stirring device at the tail end of the continuous casting machine further comprises a guide wheel set structure which can be arranged on the electromagnetic stirring device 92 at the tail end, wherein the guide wheel set structure comprises a first guide wheel set 31 which can move along the guide rail 1, and a second guide wheel set 32 which can move downwards and is terminated at the opening of the guide rail is arranged above the first guide wheel set 31.
In the installation guide structure of the electromagnetic stirring device at the tail end of the continuous casting machine, the guide wheel group structure and the guide rails arranged in pairs play a role in stably guiding the installation of the electromagnetic stirring device at the tail end, and the pull rod structure is arranged between two adjacent guide rails, so that each group of independent guide rails in pairs are connected into a whole, the strength of the equipment is greatly improved, meanwhile, the rigidity of the equipment is greatly improved, the acting force of the electromagnetic stirring device at the tail end in the process of hanging in and out is borne by all guide rails instead of a single pair of guide rails, and the possibility of deformation and displacement of the single group of guide rails is greatly restrained; the installation guide structure of the electromagnetic stirring device at the tail end of the continuous casting machine can effectively reduce the time for dismounting the electromagnetic stirring device at the tail end, lighten the labor intensity of workers and is beneficial to popularization and use.
Further, as shown in fig. 1 and 2, each guide rail 1 includes guide rail columns 11 that can be connected to both sides of the end fixing section of the continuous casting machine, one side (i.e., the inner side of the guide rail column) of each guide rail column 11, which is close to the roller row of the end fixing section of the continuous casting machine, is provided with a guide rail groove 12 in a penetrating manner, one side wall of the guide rail groove 12 is provided with a guide rail notch 13 downward from the guide rail opening, the guide rail notches 13 of the two guide rails 1 that are provided in pairs are located on the same side of the guide rail groove 12, the second guide wheel group 32 can move downward to terminate at the guide rail notch 13, and the guide rail notch 13 is used for releasing the lifting force generated on the guide rail column 11 when the end electromagnetic stirring device is removed. Because the tail end electromagnetic stirring devices with different sections are different in height and mounting positions, the guide wheel sets of the tail end electromagnetic stirring devices are different in structure, and the guide rail notches 13 of each guide rail are different in length, so that the guide wheel sets of the tail end electromagnetic stirring devices are suitable for the guide wheel sets of the tail end electromagnetic stirring devices.
In the present embodiment, the top end of the rail column 11 is inclined to form a transition slope in order to facilitate the attachment and detachment of the terminal electromagnetic stirring device.
In this embodiment, the cross section of the rail column 11 is H-shaped, the inner groove of the H-shape forms the rail groove 12, and the outer groove of the H-shape is provided with reinforcing ribs at intervals, so as to improve the strength and rigidity of the rail column 11.
In the present embodiment, as shown in fig. 1, the bottom of the rail post 11 is provided with a bracket 14 that can be attached to the end fixing section of the continuous casting machine.
Further, as shown in fig. 1 and 2, the first guide wheel set 31 includes two first rollers 311 hinged to two sides of the terminal electromagnetic stirring device, and the two first rollers 311 can move along the guide rail grooves 12 on two sides; the second guiding wheel set 32 comprises two second rollers 321 respectively arranged above the two first rollers 311, and the two second rollers 321 can respectively move downwards to end at the guide rail notch 13.
Further, as shown in fig. 1 and 2, the first guide wheel set 31 includes two roller supports 312 respectively disposed at two sides of the terminal electromagnetic stirring device, and two first rollers 311 are respectively hinged to the two roller supports 312; the second guide wheel set 32 includes a shaft sleeve structure 322 disposed on the terminal electromagnetic stirring device, and two second rollers 321 are respectively hinged at two ends of the shaft sleeve structure 322.
The guide rail groove 12 mainly guides the two first rollers 311 at the lower part of the terminal electromagnetic stirring device, whether the hanging-in or the hanging-out operation is performed. As shown in fig. 1, when the terminal electromagnetic stirring device is hung in, the two first rollers 311 at the lower part of the terminal electromagnetic stirring device are put into the guide rail groove 12 by operating the crown block, then slide down in the guide rail groove 12 by the self weight of the terminal electromagnetic stirring device, and simultaneously move along with the trolley at the upper part of the crown block until the terminal electromagnetic stirring device is correctly positioned, the whole hanging-in process always slides in the guide rail 1 by the first rollers 311 at the lower part, and the two second rollers 321 at the upper part do not participate in guiding. As shown in fig. 2, after the terminal electromagnetic stirring device is hung in place, two second rollers 321 at the upper part of the terminal electromagnetic stirring device are stationary at the positions of the guide rail notches 13. The lifting process of the tail end electromagnetic stirring device is not a simple lifting reverse process, because the wire rope only can provide vertical upward pulling force for the tail end electromagnetic stirring device when the crown block is lifted, and all the tail end electromagnetic stirring devices are not vertically arranged on the ground and are arranged on the arc of the roller row and form a certain angle with the ground, namely the lifting direction and the lifting center line of the tail end electromagnetic stirring device are not coincident, if the guide rail is made to be closed, two second rollers 321 at the upper part of the lifting process can directly transmit the lifting force of the crown block to the tail end electromagnetic stirring device vertically upwards to the guide rail to generate blocking, and if the crown block is continuously operated, the tail end fixing section of the whole continuous casting machine can be pulled up continuously, so that the method is very dangerous; however, after the guide rail notch 13 is opened at the top of the guide rail groove 12, the problem is solved, the second roller 321 at the upper part of the end electromagnetic stirring device can be immediately separated from the constraint of the guide rail 1 at the beginning of lifting, only the vertical upward moving track of the crown block is followed, only the first roller 311 at the left part slides in the guide rail groove 12, then the first roller 311 at the lower part also slides to the guide rail notch 13 at the upper part through the slow lifting of the crown block and the moving operation of the trolley at the upper part, the end electromagnetic stirring device can be smoothly lifted out, the guide rail notch 13 plays a role of leakage force, and the end electromagnetic stirring device can not directly generate lifting force on the guide rail 1 when the crown block lifts the end electromagnetic stirring device, so that the integrity and the sustainability of equipment are fully protected.
Further, as shown in fig. 1, each of the tie rod structures 2 includes an upper tie rod group including a first upper tie rod 211 and a second upper tie rod 212 detachably connected, the first upper tie rod 211 and the second upper tie rod 212 being connected with the upper portions of the adjacent two guide rails 1, respectively; the lower tie bar assembly includes a first lower tie bar 221 and a second lower tie bar 222 detachably connected, and the first lower tie bar 221 and the second lower tie bar 222 are respectively connected with lower portions of the adjacent two guide rails 1. The pull rod structures 2 connect the guide rails in a pull rod mode, the guide rails 1 on each side are connected into a whole, the rigidity of the equipment is greatly improved while the strength of the equipment is greatly improved, the acting force of the tail end electromagnetic stirring device in the process of hanging in and out is borne by all the guide rails, and the possibility of deformation and displacement of a single set of guide rails is greatly restrained.
Further, the first upper pull rod 211 and the second upper pull rod 212 are connected through an upper pull rod bolt, an upper pull rod nut and an upper pull rod gasket, and an upper pull rod adjusting gasket is propped between the first upper pull rod 211 and the second upper pull rod 212; the first lower pull rod 221 and the second lower pull rod 222 are connected through a lower pull rod bolt, a lower pull rod nut and a lower pull rod gasket, and a lower pull rod adjusting gasket is propped between the first lower pull rod 221 and the second lower pull rod 222.
Further, one side of each of the first upper tie bar 211, the second upper tie bar 212, the first lower tie bar 221, and the second lower tie bar 222 is provided with a pin hole plate 23 for connecting the heat insulation cover 91, as shown in fig. 3. The heat preservation cover 91 of the terminal fixed section of the continuous casting machine can be correspondingly improved by matching with the guide rail 1 and the pull rod structure 2 on two sides, the heat preservation cover 91 is a semi-closed structure formed by two side heat preservation covers and a top heat preservation cover, as shown in fig. 1 and 2, in order to ensure stable installation of the heat preservation covers, two sides of one end of the terminal fixed section of the continuous casting machine, which is far away from an open end, are respectively provided with a stand column structure 4, as shown in fig. 4, the stand column structure 4 comprises a stand column 41, an upper cross beam 42 and a lower cross beam 43 which extend towards two sides are arranged on the stand column 41, and pin hole plates 23 are arranged on the upper cross beam 42 and the lower cross beam 43. The improved heat preservation cover 91 supports a quick-dismantling mode, the side heat preservation cover and the top heat preservation cover are installed without any bolts, and the side heat preservation cover and the top heat preservation cover are installed and positioned by directly inserting pins into the pin hole plates 23, so that the heat preservation cover is convenient and quick.
When the heat preservation cover 91 is installed, pins of the two side heat preservation covers are aligned with pin holes on the corresponding pin hole plates 23 and accurately inserted, so that the installation can be easily completed; after the two side heat preservation covers are installed, the pin holes of the top heat preservation cover are aligned with the pins at the tops of the corresponding two side heat preservation covers, and the installation can be completed, so that the whole heat preservation cover installation process is efficient and rapid. The heat insulation cover 91 is easy to deform after being heated, so that the improved heat insulation cover 91 is not only provided with an expansion groove, but also angle steel is welded on the surface of the heat insulation cover 91 to strengthen the deformation resistance of the heat insulation cover after being heated.
Therefore, the installation guide structure of the electromagnetic stirring device at the tail end of the continuous casting machine has the following beneficial effects:
in the installation guide structure of the electromagnetic stirring device at the tail end of the continuous casting machine, the guide wheel group structure and the guide rails arranged in pairs play a role in stably guiding the installation of the electromagnetic stirring device at the tail end, and the pull rod structure is arranged between two adjacent guide rails, so that each group of independent guide rails in pairs are connected into a whole, the strength of the equipment is greatly improved, meanwhile, the rigidity of the equipment is greatly improved, the acting force of the electromagnetic stirring device at the tail end in the process of hanging in and out is borne by all guide rails instead of a single pair of guide rails, and the possibility of deformation and displacement of the single group of guide rails is greatly restrained; the guide rail notch at the top of the guide rail plays a role of releasing force, so that when the overhead travelling crane lifts the tail end electromagnetic stirring device, the tail end electromagnetic stirring device cannot directly generate lifting force on the guide rail, and the integrity and the sustainability of equipment are fully protected; the installation guide structure of the electromagnetic stirring device at the tail end of the continuous casting machine can effectively reduce the time for dismounting the electromagnetic stirring device at the tail end, lighten the labor intensity of workers and is beneficial to popularization and use.
