Embodiment
As shown in Figures 1 to 10, the present invention mainly comprises motor 1, rotating disk 2, support column 3, adjustment disk 4, lock-screw 5 and spring 6, describes the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, motor 1 is driver part of the present invention, is provided with output shaft 11 at the output of motor, is fixed with rotating disk 2 at the free end of output shaft.As shown in Figure 3, rotating disk 2 is circular metalwork, and rotating disk is provided with some slideways 21, and some slideways are evenly distributed on circumferentially same, and the length direction of slideway is arranged along the radial direction of rotating disk.Slideway runs through the both ends of the surface up and down of rotating disk, and as shown in Figure 4, Figure 5, the lower surface of rotating disk is provided with the groove 23 of a circle, and some slideways are all connected with groove.The rotating disk being positioned at groove periphery is provided with cannelure 22, and the effect of cannelure is for being rotationally connected with adjustment disk.
As shown in Figure 6, Figure 7, adjustment disk 4 is circular metalwork, is provided with centre bore 44 in the center of adjustment disk, and output shaft is fixed on rotating disk through after this centre bore.An end face of adjustment disk is installed with retainer ring 41, and retainer ring is the metalwork of annular, and retainer ring and adjustment disk coaxial line are arranged.The internal diameter of retainer ring at least should equal the aperture of centre bore, to dodge output shaft.The outer wall of retainer ring is provided with some plectrums 42, and the quantity of plectrum is identical with the quantity of slideway.Plectrum is the metalwork of circular arc, and some plectrums are uniformly distributed on the outer wall of retainer ring.The end face of adjustment disk being provided with retainer ring is fixed with installing ring 45, and installing ring and adjustment disk coaxial line are arranged, and the axial length of installing ring is greater than the axial length of retainer ring.As shown in Figure 8, during installation, the retainer ring of adjustment disk is arranged in the cannelure of rotating disk, and ensures that adjustment disk is relative fixing in the axial direction with between rotating disk, can relatively rotate between adjustment disk and rotating disk.Now, the retainer ring on adjustment disk is placed in the groove of rotating disk.Relative fixing for what realize between rotating disk with adjustment disk, in the screwed hole of adjustment disk, be provided with lock-screw 5, the other end of lock-screw holds out against on rotating disk, to realize both relatively fixing.
As shown in Figure 2, be slidably fitted with support column 3 in each slideway, support column is vertical with rotating disk to be arranged, and support column can in slideway near or away from the center of rotating disk.Spring 6 is provided with between support column with corresponding slideway, under the action of the spring, the oriented trend away from the movement of center of turntable side of support column.As shown in Figure 8, the inner side of plectrum contacts with support column, is positioned at a certain position determined at the effect lower support post of spring and plectrum.As shown in Figure 9, rotate clockwise adjustment disk, retainer ring just drives plectrum to rotate, the inner side extruding support column of plectrum, and overcome spring force effect support column is moved near the side of center of turntable, the space that now some support columns surround diminishes, to adapt to the less flange of size 7.Rotate counterclockwise adjustment disk, retainer ring just drives plectrum to be rotated counterclockwise, spring elongates by compression, and promote support column and move to the side away from center of turntable, under the action of the spring, support column still with plectrum contact internal walls, now the space that surrounds of some support columns becomes large, to adapt to larger-size flange.According to the distance size of circular hole distance flange center on flange, regulate the position of support column in slideway, should ensure in the circular hole that support column can extend on flange after adjustment, then by lock-screw locking rotating disk and adjustment disk.As shown in Figure 10, lubricating cup 8 is fixed on flange 7, and extend into by support column after in flange, drive motors 1 rotates, and support column just drives flange synchronous axial system, now just flange and lubricating cup can be unloaded from respirator, so that change moisture absorption particle, injection sealing oil.For avoiding the relative movement vertically of support column and rotating disk, be provided with the baffle plate 31 of a pair circle on the support columns, wherein a baffle plate is positioned at the upper end of rotating disk, and another baffle plate is arranged in the groove of rotating disk.
For larger transformer, the model of transformer breather also may be comparatively large, because the flange size of installing lubricating cup is comparatively large, the circular hole aperture on flange is larger.For making the circular hole on support column adaptation ring flange, external screw thread is provided with in the bottom of support column, screw thread installs circular casing on the support columns, and the circular hole aperture on the external diameter of this sleeve pipe and flange adapts, and can solve the unmatched problem of circular hole size on support column size and flange.
The number of slideway can be three, four, five even more, now the number of plectrum keeps identical with the number of slideway number, support column.Plectrum and retainer ring can be welded and fixed, and also can one-body moldedly manufacture, and integrated mode intensity is higher, the fracture at plectrum and retainer ring contact-making surface place when avoiding plectrum to drive support column to rotate.For strengthening the structural strength between plectrum and retainer ring further, between plectrum and retainer ring, also can reinforcement be set.
Support column inserts in the circular hole on flange by the present invention, when then drive motors rotates, just can drive flange synchronous axial system, the lubricating cup now just on detachable lower flange.The position of support column on rotating disk is adjustable, according on flange circular hole distance flange center distance, rotate adjustment disk make plectrum stir support column close to each other or away from, to adapt to the flange of different size.This replacing instrument can fast discharging flange, and can unload the flange of different size, highly versatile.
