Detailed Description
For example, as shown in fig. 2 and fig. 3, the telescopic base for centering detection of a continuous casting mold according to the present invention includes a frame 1, a gear 2, a motor 3, two stop pins 4, two racks 5, two telescopic blocks 6, and a plurality of support bars 7, wherein the plurality of support bars 7 are horizontally arranged in two rows at intervals along the length direction of the frame 1, each row of support bars is provided with a guide groove 71 along the length direction of the frame 1, the two racks 5 are respectively located in the guide grooves 71 of each row of support bars, the tooth surfaces of the two racks 7 are opposite and respectively located at two sides of the frame 1, the two telescopic blocks 6 are respectively located at two sides of the frame 1 and connected to the ends of the two racks 5, the two racks 5 are provided with long grooves 51 along the length direction, the two stop pins 4 are respectively vertically arranged at the top surface and the bottom surface of the frame 1 and located in the long grooves 51 of the two racks 5, the motor 3 is arranged in the middle of the bottom surface of the frame 1, and the gear 2 is connected with a rotating shaft of the motor 3 and meshed with the two racks 5.
Preferably, the end surfaces of the two telescopic blocks 6 are arc surfaces matched with the guide roller, the high point of each arc surface abuts against the diameter horizontal plane of the guide roller, and the low point of each arc surface abuts against the position between the diameter horizontal plane and the vertical plane of the guide roller. The arc-shaped surface of the end surface of the telescopic block is attached to the surface of the guide roller and can hook the surface of the guide roller, so that the telescopic base is tightly supported between the adjacent guide rollers, and conditions are created for tensioning the steel wire rope.
Preferably, the rack 5 is connected with the telescopic block 6 by a countersunk bolt 8.
Preferably, the telescopic base further comprises hanging rings 9, and the hanging rings 9 are arranged on the top surface of the frame 1 at intervals.
The continuous casting crystallizer centering instrument is used for centering measurement of the crystallizer, and the centering instrument inevitably vibrates in the operation process, which seriously influences the detection precision. The telescopic base can effectively reduce the influence of vibration on detection data, and improve the centering measurement accuracy of the continuous casting crystallizer.
As shown in fig. 4, the telescopic base is of an electric driving telescopic structure, a driving motor is rigidly connected with a gear, and the supporting surface of a telescopic block is made into a shape completely matched with a guide roller; when the telescopic base descends to the position of the guide roller at the tail end of the outlet of the crystallizer, the driving motor is started, the driving motor drives the gear to rotate, the two racks slide left and right along the guide grooves of the support bars respectively under the transmission of the gear, the left telescopic block and the right telescopic block which are fixed on the racks are opened synchronously, the support surfaces of the telescopic blocks hook the surface of the guide roller, and therefore the telescopic base is supported between the adjacent guide rollers, and the driving motor stops. Wherein the stop pin is used for limiting the maximum opening position of the telescopic block. After the telescopic base is fixed, the centering instrument can tighten the steel wire rope, and the data acquisition device ascends along the steel wire rope to realize data acquisition; after the measurement is finished, the driving motor is started to rotate reversely, and the telescopic blocks are all retracted into the frame under the driving of the gear and the rack. The telescopic base can effectively reduce the vibration caused by the continuous casting crystallizer centering instrument during detection operation, so that the data acquired by the data acquisition device is more accurate.
The telescopic base has the following main functions: 1. the counter weight is laid as a walking flexible track of the centering instrument data acquisition device; because the steel wire rope used as the walking guide of the data acquisition device is flexible, the balance weight is added to ensure that the data acquisition device keeps smooth in the descending process, and the shaking of the data acquisition device and the shaking of the steel wire rope are reduced. 2. The support point is used as a far-end support point of the flexible track for the centering instrument to travel; one end of the steel wire rope is fixed on the steel wire rope winding drum of the centering instrument, the other end of the steel wire rope is fixed on the telescopic base, and the steel wire rope is tensioned to serve as a flexible track for the data acquisition device to walk. 3. The rigidity of the flexible running track of the centering instrument is improved, and shaking is prevented; when the telescopic base hooks the guide roller, the rigidity of the steel wire rope serving as the flexible track is improved after the steel wire rope is tensioned, and the data acquisition device can be effectively prevented from shaking during walking. 4. Cameras can be arranged on two sides of the telescopic base, and the function of manually checking the key area of the crystallizer and the state between the rollers is simulated. Because of the narrow space in the continuous casting machine, manual inspection is difficult even in a shutdown state. Therefore, the camera is arranged on the telescopic base and used for shooting conditions such as nozzles, slag inclusion and the like in the casting machine in the up-and-down process instead of manual work. In the process of starting up and down lifting of the telescopic base, shooting is carried out through the camera, and shot images are displayed on a display screen of the centering instrument.
The telescopic base is an auxiliary function module of the centering instrument, so that the whole measuring process tends to be more stable, the centering measuring accuracy of the continuous casting crystallizer is improved, and the acquired data has higher reference value. Therefore, the arc alignment precision of the wide-surface foot roller and the supporting guide roller of the crystallizer is more close to the actual standard, and the alignment adjustment operation of the crystallizer is guided. By improving the centering precision control of the crystallizer, the surface quality problem of the casting blank can be effectively reduced, the problems of transverse crack defect, longitudinal crack defect and the like of the casting blank corner are solved, and the product quality is improved.
