[0028] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0029] Embodiment one:

[0030] A kind of iron core reactor shock absorbing installation base, as shown in Fig. Figs. 1-4 It includes vertical channel steel 1, iron core reactor bottom channel steel 2, L-shaped rubber pad 3, floor embedded part 4 and angle steel fixing part 5.

[0031] Vertical channel steel 1, L-shaped rubber pad 3, floor embedded part 4 and angle steel fixing part 5 are provided with two groups, and are symmetrically arranged on the left and right sides of iron core reactor bottom channel steel 2.

[0032] Among them, floor embedded part 4 is embedded and fixed in floor, and vertical channel steel 1 is fixed on the top of floor embedded part 4 by welding;L-shaped rubber pad 3 covers the upper wing plate of vertical channel steel 1;At the same time, bolt holes are formed at both ends of vertical channel steel 1, and angle steel fixing part 5 is fixed on vertical channel steel 1 through the threaded connection of bolt holes at both ends and fastening bolt 7, and rubber pad layer 6 is arranged on the vertical surface of angle steel fixing part 5.In addition, two groups of angle steel fixing part 5 clamp iron core reactor bottom channel steel 2 in the middle, vertical damping layer (including horizontal and vertical) is formed by vertical channel steel 1 and L-shaped rubber pad 3, and horizontal buffer layer composed of rubber pad layer 6 arranged on the vertical surface of angle steel fixing part 5, wherein the vertical damping layer is used for absorbing vertical vibration, the horizontal buffer layer is used for absorbing horizontal vibration, and the two are combined to realize vibration isolation.

[0033] And vertical channel steel 1 is C-shaped channel steel, iron core reactor bottom channel steel 2 is I-shaped channel steel, and two groups of vertical channel steel 1 are symmetrically arranged on the left and right sides to clamp the recesses on the left and right sides of iron core reactor bottom channel steel 2 to form interlocking structure, wherein the top wall of vertical channel steel 1 abuts against the upper flange bottom wall of iron core reactor bottom channel steel 2 through the horizontal end of L-shaped rubber pad 3, the side wall of vertical channel steel 1 abuts against the inner side wall of web of iron core reactor bottom channel steel 2 through the vertical end of L-shaped rubber pad 3, and there is a gap between iron core reactor bottom channel steel 2 and floor, so as to form a suspended installation structure, so that the iron core reactor can move up and down in the installation base to release vibration energy.The vertical end of L-shaped rubber pad 3 is arranged between the joint between vertical channel steel 1 and iron core reactor bottom channel steel 2, which avoids causing great wear of vertical channel steel 1 in the process of moving up and down of iron core reactor bottom channel steel 2.

[0034] Then, the length of the vertical channel steel 1 is greater than that of the bottom channel steel 2 of the core reactor, so that the two vertical channel steels 1 can limit the bottom channel steel 2 of the core reactor horizontally, and the bottom of the core reactor is not in direct contact with the floor.

[0035] Then, the thickness of the L-shaped rubber pad 3 and the rubber pad layer 6 is not less than 20 mm, so that the damping effect of the two is ensured. In addition, the rubber pad layer 6 is fixed and limited horizontally by the pre-tightening force between the angle steel fixing part 5 and the bottom channel steel 2 of the core reactor during installation, and small displacement is allowed, so that the displacement problem caused by electromagnetic force is solved. At the same time, the height of the bottom of the suspension type installation structure is not less than 30 mm, which matches the stiffness of the L-shaped rubber pad 3 and the rubber pad layer 6, so that the system natural frequency is adjusted outside the sensitive frequency band of the building structure, and the resonance risk is avoided.

[0036] In addition, the size of the floor embedded part 4 is greater than the wing plate size of the vertical channel steel 1 and is 5-10 mm higher than the floor surface 5, so that the welding space of the vertical channel steel 1 and the floor embedded part 4 is ensured, and the connection between the floor embedded part 4 and the vertical channel steel 1 is stable.

[0037] Finally, the vertical channel steel 1 and the floor embedded part 4 are welded to form a foundation frame, and vibration isolation is realized through double-layer damping design. The L-shaped rubber pad 3 is arranged on the wing plate of the channel steel to absorb vertical vibration, and the angle steel fixing part 5 with the rubber pad 6 is used to realize horizontal limiting and buffering. The unique suspension type structure makes the bottom of the reactor keep a distance of more than 30 mm from the floor, and cooperates with the damping characteristics of the rubber material, so that the vibration transmission rate can be effectively reduced, and the resonance frequency is avoided in the sensitive frequency band of the building structure, so that the safety of the equipment and the building is effectively guaranteed.

[0038] Embodiment two: contains all the contents of embodiment one:

[0039] As shown in Figs. 5-6 Because the width of the bottom channel steel 2 of the core reactor is large, in order to reduce the overall weight, a hole is vertically arranged in the middle of the bottom channel steel 2 of the core reactor, the hollow design of the middle of the bottom channel steel 2 of the core reactor is more suitable for inhibiting high-frequency vibration of the core reactor, and the connecting plates 21 are arranged at the front and rear ends of the bottom channel steel 2 of the core reactor to enhance the structural strength, and the connecting plates 21 are provided with holes in the middle to facilitate hoisting equipment.
