Detailed Description
The present invention will be described in detail with reference to examples, but the scope of the present invention is not limited to the examples.
As shown in figures 1-7, the large centrifugal ventilator steel frame mounting structure comprises a damping support 2, a damping chassis 3 and a damper 4, wherein the damper 4 is arranged on a site high platform, the damping chassis 3 is connected with the damper 4 through bolts, and the damping support 2 is fixed on the damping chassis 3 in a welding mode.
The damping bracket 2 comprises a steel pipe beam 11 and a steel plate panel 12, wherein the steel pipe beam 11 and the steel plate panel 12 are welded into a hollow steel frame with a trapezoid cross section, the steel pipe beam 11 is provided with a filler hole, and the steel plate panel 12 is also provided with a filler hole 8.
For the aesthetic appearance of the steel plate panel 12 and the exterior of the steel pipe beam 11, the filler holes on the steel pipe beam 11 are arranged in the hollow steel frame. When concrete is poured into the steel pipe beam 11, the concrete enters the hollow steel frame through the manhole door 9 to operate.
Manhole doors 9 are arranged on the inclined planes on the two sides of the trapezoid.
The upper end of the shock absorbing bracket 2 is also fixed with a transmission group mounting bracket 7 for mounting the transmission group 6.
The damping chassis 3 comprises a steel pipe beam 11 and a steel plate panel 12, wherein the steel pipe beam 11 and the steel plate panel 12 are welded to form a rectangular plate structure, and a filler hole 8 is formed in the steel pipe beam 11.
