Description

Technical Field

[0001] The utility model relates to the technical field of steel production, in particular to a walking beam with an eccentric wheel group quick-disassembly structure. Background Art

[0002] The walking beam is the last station in the thin slab continuous casting and rolling process. The steel coil moves in a stepping manner on the transport chain. The eccentric wheel of the walking beam realizes the up and down movement of the walking beam during the rolling process to achieve the lifting and lowering of the steel coil. The eccentric wheel rotates, and after the walking beam moves to the predetermined stroke height, the eccentric wheel continues to rotate and puts the walking beam in a low position, and then continues to rotate back to the initial position, and so on, to send the steel coil to the finished product warehouse. Therefore, as a heavy-duty load-bearing component, the eccentric wheel group has a relatively short service life. If the bearing is damaged, the entire eccentric wheel group needs to be replaced in time.

[0003] In the related art, the eccentric wheel of the eccentric wheel group is assembled between the walking beam and the beam group cover, and the wheel is supported on the track. To replace the bearing, it is necessary to first clear all the steel coils on the walking beam, remove the beam group cover, lift the walking beam and exceed the usual lifting position and position it, then remove the connecting rod and cylinder in turn, pull out the eccentric wheel group, install the new eccentric wheel group in place after the disassembly, then install the connecting rod and cylinder, and then release the positioning and lower the walking beam. The working hours are long, the operation time is generally not less than eight hours, the lifting risk factor is high, and the labor intensity is high.

[0004] In view of this, it is necessary to propose a walking beam with an eccentric wheel group quick-release structure to solve the above defects. Utility Model Content

[0026] Please refer to Figure 1-Figure 3The utility model provides a walking beam with an eccentric wheel group quick-release structure. The walking beam with an eccentric wheel group quick-release structure comprises a track frame 1, a track 2, a beam body 3, a beam group cover 4 and an eccentric wheel group 5. The eccentric wheel group 5 comprises an eccentric wheel 51 and a wheel 53 assembled in one body, the track 2 is detachably mounted on the track frame 1 by bolts, the wheel 53 is supported on the track 2, the track 2 is divided into at least two sections, the bottom of the beam body 3 and the beam group cover 4 are assembled on the outer periphery of the eccentric wheel 51 of the eccentric wheel group 5, and the combined surface 6 between the beam body 3 and the beam group cover 4 is an inclined surface. By setting the combined surface 6 between the beam body 3 and the beam group cover 4 as an inclined surface, and the track 2 is spliced ​​by multiple sections, when disassembling the eccentric wheel group 5, first remove the section of the track under the wheel, then remove the beam group cover 4 to make the eccentric wheel group 5 sink to a certain height, and finally pull out the eccentric wheel group 5 horizontally. Similarly, when installing the eccentric wheel group 5, push the eccentric wheel group 5 horizontally into the installation position, install the beam group cover 4 on the beam body 3, and finally install the removed track. There is no need to lift the entire steel coil and the beam body 3, which reduces the operating procedures, realizes the quick disassembly and installation of the eccentric wheel group 5, improves work efficiency, eliminates the lifting and hoisting procedures, reduces the risks to personnel during the disassembly and installation process, and reduces labor intensity.

[0027] It should be explained that the combination surface 6 is the plane where the two are in contact when the beam assembly cover 4 is assembled on the beam body 3. Specifically, in the present embodiment, the angle between the combination surface 6 and the horizontal plane is 40-50°. That is, the angle can be 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49° or 50°. Preferably, the angle between the combination surface and the horizontal plane is 45°. It should be noted that the opening angle of the combination surface is the main factor that determines whether the eccentric wheel group 5 can be pulled out from the inclined direction. Therefore, in the present embodiment, 45° is preferred.

[0028] See also Figure 3 Further, a stopper 7 is provided on the combination surface 6 of the beam assembly cover 4 or the beam body 3, and a stopper groove 8 matching the shape of the stopper 7 is provided on the beam body 3 or the beam assembly cover 4. When the beam body 3 and the beam assembly cover 4 are assembled, the stopper 7 is inserted into the stopper groove 8. It can be understood that the arrangement of the stopper 7 and the stopper groove 8 makes the matching installation between the beam assembly cover 4 and the beam body 3 more compact.

[0029] The beam assembly cover 4 is bent and extended from the ends of both ends thereof to form a lug 9, and the fastener passes through the lug 9 and is fixedly connected to the beam body 3. The stopper 7 is formed on the lug 9, and the stopper groove is provided at a position corresponding to the stopper after the beam assembly cover 4 is installed on the beam body. The lug 9 is bent and extended toward the outer periphery of the beam assembly cover 4 to form a portion for assembly, so as to improve the assembly degree between spare parts.

[0030] In addition, the outer circumference of the eccentric wheel 51, the beam assembly cover 4, and the combined surface of the beam body 3 are connected by a stopper structure 10. The stopper structure 10 is formed on the working surface of the three, that is, the entire outer circumference of the eccentric wheel, and the inner circumference of the beam assembly cover 4 and the beam body 3, so as to improve the structural coordination of the three and make the connection structure more compact.

Preferably, the beam body 3 is in a gate shape.

[0032] Eccentric wheel replacement operation process: move the walking beam to the end of the stroke, turn off the power, put a sign to stop the hydraulic pressure relief, set a fulcrum at the track 21 to be disassembled under the eccentric wheel group 5 to be replaced, and use the jack to slightly lift the beam body 3 of the walking beam until the wheel 53 is no longer loaded, first remove the step pins of the connecting rod 11 and the oil cylinder 12, and use the hoist to lift the eccentric wheel group 5 to be replaced, first remove the bolts of the track 21 to be disassembled, remove the track 21 to be disassembled, and then loosen the beam group cover 4, operate the hoist to slowly drop the eccentric wheel group 5 on the track frame 1 and then lift it away, lift the new eccentric wheel group 5 onto the track frame 1, and use the hoist to slowly pull it to the installation position, and then install the beam group cover 4 at the bottom of the beam body 3, then install the disassembled track 21, and finally install the connecting rod 11 and the oil cylinder 12, remove the jack, remove the sign, power on, and start hydraulic commissioning. The replacement work is completed.

[0033] The walking beam with an eccentric wheel group quick-disassembly structure provided by the utility model sets the combined surface 6 between the beam body 3 and the beam group cover 4 as an inclined surface, and the track 2 is composed of multiple sections. In this way, when disassembling the eccentric wheel group 5, a section of the track under the wheel is first removed, and then the beam group cover 4 is removed to make the eccentric wheel group 5 sink to a certain height, and finally the eccentric wheel group 5 is pulled out horizontally. Similarly, when installing the eccentric wheel group 5, the eccentric wheel group 5 is horizontally pushed into the installation position, and the beam group cover 4 is installed on the beam body 3, and finally the disassembled track is installed. There is no need to lift the entire steel coil and the beam body 3, which reduces the operating procedures, realizes the quick disassembly and installation of the eccentric wheel group 5, improves work efficiency, eliminates the lifting and hoisting procedures, reduces the risks to personnel during the disassembly and assembly process, and reduces labor intensity.
