[detailed description of the invention]
Below in conjunction with accompanying drawing, following further illustrating is done to the utility model:
As shown in drawings, the utility model comprises: furnace roof 1, body of heater 2, bolt assembly 3, packing 4, yoke 5, coil 6 and yoke fastening assembly 7, furnace roof 1 and body of heater 2 are connected to one by bolt assembly 3, packing 4 is equipped with between furnace roof 1 and body of heater 2, furnace roof 1 vertically presses in coil 6, and furnace roof 1 and coil 6 top fit tightly, and coil 6 circumferential distribution has many yokes 5, yoke 5 is uniformly distributed along coil 6 radial direction, and yoke 5 is fixed on coil 6 periphery by yoke fastening assembly 7.
Wherein, yoke fastening assembly 7 comprises adjustment bearing pin 8, locking plate 9, dish-shaped elastomeric pad 10 and tightening parts 11, regulate bearing pin 8 end that tightening parts 11 are installed, tightening parts 11 are connected with yoke 5, regulate between bearing pin 8 and tightening parts 11 and be provided with dish-shaped elastomeric pad 10, regulate the other end of bearing pin 8 to be provided with locking plate 9; This dish-shaped elastomeric pad 10 can be provided with 8, and dish-shaped elastomeric pad 10 is superimposed rear formation four groups between two, and the dish mouth of every two groups of dish elastomeric pads 10 is relative.Yoke fastening assembly 7 can be provided with multiple, and yoke fastening assembly 7 is distributed in the upper and lower side place of yoke 5 periphery.
In the utility model, body of heater and furnace roof are coupled together by bolt assembly by furnace roof, and between furnace roof and body of heater, place packing, packing itself is a kind of elastic material, produces pretightning force after can being compressed simultaneously.During installation, after furnace roof fits tightly with coil, start stubborn bolt assembly, the order of tightening of bolt is symmetry direction, and the moment of torsion tightening this bolt assembly is preferably 500N.M, and packing also has certain decrement simultaneously.By this fixed form, coil can in time by furnace roof from axially compressing, upper and lower play when avoiding work.
When coil is in place and by after yoke centering, timely fastening yoke fastening assembly.In this fastening yoke fastening assembly, the Main Function regulating bearing pin is by the relative displacement of movable control tightening part for coil, with the activity space of control coil.The effect of locking plate is locked in time after adjustment pin axial adjustment puts in place, prevents from getting loose.The Main Function of dish elastomeric pad provides certain pretightning force to tightening part, avoids winding deformation, and different according to the type of furnace, the quantity of the dish-shaped elastomeric pad of configuration also can be variant, in general can use 8 dish-shaped pads, be divided into four groups and regulate, conventional pretightning force is 30050N.
As shown in Figure 4, when the dish-shaped elastomeric pad in yoke fastening assembly is free state, the gap d 1 between dish-shaped shim pack is 2.8MM.As shown in Figure 5, for dish-shaped elastomeric pad compress completely time, the gap d 2 between dish-shaped shim pack is 0MM, and the pretightning force of generation is 39600N.As shown in Figure 6, for dish-shaped elastomeric pad 70% compress time, the gap d 3 between dish-shaped shim pack is 1MM, and the pretightning force of generation is 30050N.
By monitoring the gap between dish-shaped shim pack, be used for judging the tightening state of yoke, if there is excesssive gap, fastening in time, avoid winding deformation.Gap between this dish-shaped shim pack is preferably 1MM, and pretightning force is 30050N.By adopting the coil fastening means of this type, and coordinating regular fastening, observing the gap of following the tracks of dish-shaped pad in time, the metaboly that gets loose of coil can be avoided in time, produce a desired effect.
The utility model is not by the restriction of above-mentioned embodiment; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
