The opposite end in coaming plate 8 and through the coaming plate 8 is stated, the coaming plate 8 is set as integrated formed structure, is arranged in opening and limits
Component, SCR casees 1 are fixed on wherein, are not necessarily to band bundled fixed, such 1 itself fixing-stable of one side SCR casees will not occur
On the other hand the case where band is broken by overlapping holder on coaming plate 8, can flexibly increase and decrease the number of the fixed point of connector
Amount and position.
Further, the top of the coaming plate 8 is fixed with support plate 9, reinforcing plate 10 and cover board 11, and the support plate 9 is equipped with
Two, two support plates 9 are arranged in parallel, and the cover board 11 and the reinforcing plate 10 are set between two support plates 9, described
Reinforcing plate 10 is triangular structure, and two angles end of the reinforcing plate 10 is fixedly connected with two support plates 9 respectively, described to add
Another angle end of strong plate 10 is fixedly connected with the middle part of the cover board 11, and the both ends of the cover board 11 are prolonged towards the supporting block 3
It stretches to form bending 12, the bending 12 is pressed on the damping rubber pad 7 and is fixedly connected by bolt with the supporting block 3.
Reinforcing plate 10 is designed as triangle harden structure, and such three angles end forms the triangle fixed structure in horizontal direction, cover plate 11
As intermediate connector, the triangle that the first fixed point, the second fixed point and the third fixed point in vertical direction form is fixed
Structure is bound up with the triangle fixed structure in horizontal direction, plays synergistic effect, greatly improves the fixation of fixing piece
Intensity and strong degree.
Further, the second connecting portion includes the supporting rod 6 of bending structure, and the first end of the supporting rod 6 passes through
Bolt is fixedly connected with above support 2, and the second end of the supporting rod 6 is fixedly connected with the fixing piece with shape by bolt
