The technical scheme of the invention is as follows: the device comprises an upper frame, a spring plate, a first wedge plate, a second wedge plate, a foundation plate, a first filler strip, a second filler strip, a third filler strip, a fixing device and an installation tool; the upper frame is connected with the foundation plate through the spring plate, the first pad strip, the second pad strip and the third pad strip are fixed on the foundation plate, the spring plate is tightly pressed against the first pad strip and the third pad strip, a first groove and a second groove are machined in the outer side of the upper frame, one side of the mounting tool is fixed at the positions of the first groove and the second groove of the upper frame, and the other side of the mounting tool is fixed with the foundation plate.
In the elastic device of the upper frame of the generator motor, the spring plate is made of forged steel 35CrMo, the smooth finish on both sides of the spring plate is Ra6.3, a gap exists between the spring plate and the third filler strip, and the spring plate elastically deforms when stressed.
In the elastic device for the upper frame of the generator motor, the flatness of the mounting tool during processing of the upper surface and the lower surface is 0.1mm, and the relative parallelism is 0.1 mm.
In the elastic device of the upper frame of the generator motor, the middle of the upper frame is provided with a third groove, the first wedge plate and the second wedge plate are tightly fastened at the third groove, and the gap between the spring plate and the third filler strip is 5 mm.
In the elastic device of the upper frame of the generator motor, the fixing device fixes the spring plate above, below and on the left and right sides of the spring plate.
The beneficial technical effects of the invention are as follows:
1. the elastic device converts the radial force of the upper frame on the foundation into the deformation of the spring plate, and can effectively reduce the radial force directly acting on the foundation concrete, thereby playing a role in protecting the foundation concrete and improving the stability of the unit.
2. The spring plate is made of high-strength forged steel materials, so that the problems of long purchase cycle, high cost and the like of a damper device when a damper and other structures are adopted can be solved.
3. The base plate in the invention can adjust the flatness between the base plate and the upper frame through the mounting tool, and can solve the problem of position deviation of the base plate in the concrete pouring process.
4. The spring plate is simple in structure and convenient to maintain, and compared with the traditional damper and other structures, the spring plate reduces the subsequent maintenance cost.
