Description
Technical field
The utility model relates to crystallizer vibrating system.
Background technology
The crystallizer of conticaster is the key equipment of conticaster, for the base shell that prevents to solidify in the casting process and crystallizer stick together and break strand, crystallizer is vibrated.Usually, provide required vibration by mould vibration device to crystallizer.Mould vibration device generally includes upper frame, underframe and makes upper frame that the four-wheel centering type device of vibration take place.
Four-wheel centering type device comprises two pairs of eccentric mechanisms that eccentric throw is different that are provided with along the cast direction, i.e. two inner arc eccentric mechanisms and two outer arc eccentric mechanisms, these two inner arc eccentric mechanisms comprise eccentric wheel that is fixed on the underframe and the connecting rod that is used to be connected each eccentric wheel and upper frame separately with two outer arc eccentric mechanisms.By the different inner arc eccentric mechanism of eccentric throw and the eccentric motion of outer arc eccentric mechanism, so that upper frame produces imitative arc vibration.Should imitative arc vibration need make four eccentric mechanisms satisfy certain phase place and amplitude relation.Usually, can by control device for example the program of computer calculate the amplitude of each eccentric mechanism.And the phase relation of four eccentric mechanisms need satisfy synchronous requirement, and promptly four eccentric mechanisms height point of reaching eccentric motion when operation simultaneously also reaches the low spot of eccentric motion simultaneously.
Eccentric wheel is made of parts such as eccentric bushing, dial and bearing blocks, and in theory, the amplitude that calculates according to the computer equal controller is adjusted to scale corresponding on the dial with the pointer of eccentric bushing and promptly can be satisfied requirement to phase place and amplitude.But because there is accuracy of manufacture error inevitably in eccentric wheel, thereby can't only himself satisfy the required phase place and the requirement of amplitude by adjusting.Therefore, need detect the vibration and the corresponding adjusting eccentric wheel of upper frame by checkout gear, to satisfy the required phase place and the requirement of amplitude.
Below with reference to Fig. 1 traditional crystallizer vibrating system and operation thereof are described.
As shown in Figure 1, crystallizer vibrating system comprises upper frame 1, underframe 2 and four eccentric mechanisms.Wherein, these four eccentric mechanisms are divided into a pair of inner arc eccentric mechanism 3 and a pair of outer arc eccentric mechanism 4.Wherein, the structure of inner arc eccentric mechanism 3 and outer arc eccentric mechanism 4 is basic identical, only makes an explanation by the structure that inner arc eccentric mechanism 3 is described below.Inner arc eccentric mechanism 3 comprises connecting rod 3a and eccentric wheel 3b, eccentric wheel 3b comprises parts such as eccentric bushing, dial, bearing block, wherein, eccentric bushing is provided with locating slot 3c, bearing block has the fastener hole corresponding with locating slot 3c, is used for by bolt eccentric bushing being fixedlyed connected with bearing block when regulating eccentric wheel.Because bearing block is fixed on the underframe 2, thereby four eccentric bearing blocks have identical location benchmark.Therefore, the locating slot by four eccentric eccentric bushings is fixedlyed connected each eccentric eccentric bushing and can be made four eccentric phase places satisfy the spikes/low-points that reaches eccentric motion simultaneously with bearing block separately.Inner arc eccentric wheel 3b is fixed on the underframe 2, and is connected in upper frame 1 by connecting rod 3a, thereby the eccentric motion by inner arc eccentric wheel 3b is to upper frame 1 transmitting vibrations.In like manner, outer arc eccentric mechanism 4 also by same structure to upper frame 1 transmitting vibrations, thereby make upper frame 1 produce imitative arc motion.Crystallizer 8 is installed on the upper frame 1, thereby vibrates by imitative arc motion.

The following describes the process that detects and adjust crystallizer vibrating system.
At first, the eccentric wheel of inner arc eccentric mechanism 3 and outer arc eccentric mechanism 4 is connected in drive unit (for example motor) by parts such as shaft couplings, vibrates to drive upper frame 1.By the distance between the upper frame 1 of displacement transducer 6 measurement displacement transducers 6 and its below, can obtain the amplitude at the position that is positioned at these displacement transducer 6 belows of upper frame 1.Whether controller 5 judges according to the measurement result of four displacement transducers 6 whether current vibration suits the requirements, be imitative arc motion promptly.As not being, then calculate each eccentric theoretical amplitude, and regulate each eccentric wheel according to theoretical amplitude.
When regulating amplitude, the eccentric wheel of inner arc eccentric mechanism 3 and outer arc eccentric mechanism 4 is thrown off from its drive unit, to regulate.Regulate inner arc eccentric wheel 3b below by explanation the eccentric process of regulating is described.The bolt (not shown) is passed the locating slot 3c that bearing block inserts eccentric bushing, make eccentric bushing fixedly connected with bearing block, promptly can not rotate with dial.When eccentric wheel moved, eccentric bushing and dial were fixing with together running by clamping screw, thereby the insertion bolt can make dial to rotate.Then, unload locking eccentric bushing and dial clamping screw so that dial can rotate with respect to eccentric bushing.By the hand rotation dial, make required amplitude (being the theoretical amplitude that controller 5 is calculated) on the pointed dial of eccentric bushing.Then, clamping screw is installed, is made eccentric bushing and dial to rotate so that bolt is fixed and unloaded to eccentric bushing and dial.According to the method described above, each eccentric wheel is regulated, at last each eccentric wheel is connected in drive unit, to try out.During trial run, detect each position amplitude by displacement transducer 6 once more, and judge whether to satisfy the condition that imitative arc moves, repeat aforesaid operations according to result of calculation as not satisfying again by controller 5.
As mentioned above, owing to displacement transducer 6 is installed on the pedestal 7a by cantilever mechanism 7b, and pedestal 7a is installed on the base station 9 that is fixed in ground.Thereby the actual vibration that is upper frame 1 with respect to ground of sensor 6 measurements.And eccentric wheel is installed on the underframe 2, that is to say the actual vibration that is upper frame 1 with respect to underframe 2 of the vibration that mould vibration device provides.Adopt traditional detection adjusting device, when ground vibrates (for example vehicle, equipment operation, and personnel's vibration of on base station, walking about etc. and to cause) time, displacement transducer 6 all can detect strong rocking, and these rub-out signals are sent to controller 5, thereby theoretical amplitude and actual needs that controller 5 calculates occur than large deviation.Then the adjusting of carrying out according to theoretical amplitude may be run counter to desire.In addition, displacement transducer 6 is installed in the boom tip of suspension arm mechanism 7b, also can't guarantee the position of displacement transducer 6 when on ground vibration taking place, and what also just can't guarantee displacement transducer 6 sensings is the displacement at the same position of upper frame 1.
