Transformer after installation at work, can produce vibration and noise, this long-term vibration and noise and people is known from experience Produce harm.In the present embodiment, as described in Figure, the dividing plate base includes X-type support 18, perpendicular support 21, damping device, drop Make an uproar device 23, support platform 17 and mobile device 22；The support platform 17 is shaped as rectangle；The perpendicular support 21 is installed on The corner location of the lower section of support platform 17；The damping device is installed on the lower section of support platform 17；X-type support 18 is installed on branch Middle position below support arrangement；The denoising device 23 is located at the lower section of perpendicular support 21, and parallel with support platform 17；It is described Mobile device 22 is located at the lower section of denoising device 23, and mobile device 22 is in same central axis with perpendicular support 21；The damping Device is made up of damper I and damper II20, damper I and is parallel to each other between damper II20；The damper I by Damper 19 is wrapped up by spring I20, and damper I is located at the centre position of perpendicular support 21, and perpendicular support 21 is divided for upper and lower ends； The damper II20 is spring I20, and damper II20 sides are located at the intersection of X-type support 18, opposite side connection drop Make an uproar device 23；The denoising device 23 is made up of steel plate and acoustic damping materials, is up and down steel plate, and centre is using acoustic damping materials as folder Layer, for reduce transformer vibration caused by noise, prevent from passing to interior of building.The mobile device 22 is by shell, roller 28 and locking device form, the shell is shaped as isosceles trapezoid, and the roller 28 is installed on enclosure middle position； The locking device is located at the surface of roller 28；The locking device includes bolt 26, spring II30, brake block a29, brake Piece b27, support 24 and hinge 25；The bolt 26 is wrapped up by spring II30；Spring II30 is installed on brake block a29 and brake block Between b27；The brake block a29's and brake block b27 is shaped as arc；The support 24 is installed on the top of hinge 25；Stop The bottom on car piece a29 top, brake block b27 top and support 24 is fixed by hinge 25；The brake block a29's Rubber is pasted in bottom and brake block b27 bottom, and such design can increase frictional resistance of the brake block between roller 28, More effectively holding roller 28 can be crossed, avoids the rotation of roller 28；The bolt 26 is overall to run through brake block a29 and brake block B27 medial arc section；The spring II30 is located at the centre position of bolt 26, and in brake block a29 and brake block b27 Between；By bolt 26 and spring II30 Combination Design, bolt 26 can screwing by regulating bolt 26, can extrusion spring II30, roller 28 can be fixed well, and because spring II30 presence, after bolt 26 is unscrewed, spring II30 It can reset, while drive separating for brake block a29 and brake block b27, now roll to be rolled again.

Operation principle：

When occupied elevator is run up, by sensor a2 and sensor b3 detections running rope rope a4 and rope b5 Pulling force, control platform is transmitted a signal to, control platform control motor 8 is rotated forward, and now drum gear I6 is carried out suitable Hour hands are rotated, and rope a4 and rope b5 are batched in drum gear I6, are pulled car 1 to move upwards, are protected during this It is consistent with rope lengths to demonstrate,prove rope a4, avoids car 1 from producing inclination.Due to car 1 being pulled up so that drum gear I6 On have larger torque, due to drum gear I6 gear end and drum gear II10 gear end intermeshing, drum gear I6 gear end is set to gear wheel 7, and roller II gear end is set to little gear 9, therefore is driven bigger.Produced in ascending for elevator Raw high-torque, when being transmitted to by gear ratio calculation on drum gear II10, its torque is obviously reduced, and now control platform controls The rotating speed of torque motor 13, its torque exported is set to be balanced each other with the torque on drum gear II10 so that elevator can be steady It is up.When elevator is descending, by the pulling force on sensor a2 and sensor b3 detections running rope rope a4 and rope b5, signal is transmitted To control platform, control platform control motor 8 is inverted, and now drum gear I6 is rotated counterclockwise, rope a4 Decontroled with rope b5 in drum gear I6, car 1 is begun to decline, and rope is less than to torque caused by drum gear I6 Torque caused by elevator rising, the rotating speed of now control platform increase torque motor 13, so as to reduce the defeated of torque motor 13 Go out torque, ensure that rope a4 in hoistway, rope b5 resultant moment and the outer rope c11 of hoistway torque mutually balance, ensure elevator Steady decline.

When there is passenger in elevator, transformer provides different voltage to each electric component in car 1, ensures each electricity The operating voltage of gas component.Transformer needs with external circuit to be connected by outlet copper bar 32, by changing outlet copper bar 32 Surface radiating insulating coating, more effectively outlet copper bar 32 can be insulated and be radiated.When installing transformer, from installation Easy angle is set out, and mobile device 22 is installed on the base of transformer, by the roller 28 in mobile device 22, can be facilitated Change of the transformer on the position in installation process；In moving process, between brake block a29, brake block b27 and roller 28 In the presence of interval, after shift position is fixed, the bolt 26 of locking device is screwed, makes brake block a29's and brake block b27 Bottom rubber part is pressed on the surface of roller 28, and now roller 28 is held tightly, and whole transformer is fixed.When needing transformer When position needs to change, the bolt 26 in locking device is unclamped, spring II30 resets, and drives brake block a29 and brake block b27 Bottom rubber part leave on the surface of roller 28, now roll to roll again.Transformer after installation at work, can produce Raw vibration and noise, this long-term vibration and noise are known from experience to people produces harm, therefore is mounted with damping in dividing plate base Device I and damping device II and denoising device 23；In the centre position of perpendicular support 21 of support platform 17, installation damping device I makes Most transformer vibration can effectively be reduced by obtaining, and damper II20 is arranged on the intersection of X-type support 18, Ke Yijin One step carries out cushioning effect to transformer；Denoising device 23 being capable of noise caused by less transformer；By damping device I and Damping device II and the three of denoising device 23 combination can ensure the beneficial effect of noise reduction and damping.
