The inner side walls of the two groups of mounting plates are slidably connected with a clamping plate matched with the steam turbine body. A first shock-absorbing damping rod and a first shock-absorbing spring are arranged between the clamping plate and the mounting plate. A locking handle is arranged at one end of the first bidirectional lead screw.

[0021] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0022] Embodiment 1, a shock-absorbing mounting base for a steam turbine in a power plant, comprises a retractable bottom plate 1 and a steam turbine body 2, characterized in that:

[0023] The retractable bottom plate 1 is provided with two sets of sliding grooves 3, and two sets of movable brackets 4 are slidably connected in the two sets of sliding grooves 3, and the two sets of movable brackets 4 are driven by a power device;

[0024] The two groups of movable brackets 4 are rotatably connected with a first bidirectional lead screw 5, and are slidably connected with two groups of mounting plates 6 threadedly connected with the first bidirectional lead screw. The inner side walls of the two groups of mounting plates 6 are slidably connected with a clamping plate 7 matched with the steam turbine body 2. A first shock-absorbing damping rod 8 and a first shock-absorbing spring 9 are provided between the clamping plate 7 and the mounting plate 6. A locking handle 10 is provided at one end of the first bidirectional lead screw 5.

[0025] Four groups of bases 11 are arranged at the bottom of the retractable base plate 1 , and second shock-absorbing damping rods 12 and second shock-absorbing springs 13 are arranged between the four groups of bases 11 and the retractable base plate 1 .

[0026] Furthermore, the power device includes a bidirectional motor 14 in the sliding groove 3, and the output end of the bidirectional motor 14 is provided with a first lead screw 15 and a second lead screw 16, the thread directions of the first lead screw 15 and the second lead screw 16 are opposite, the first lead screw 15 and the second lead screw 16 are threadedly connected to the movable bracket 4, and the bidirectional motor 14 is electrically connected to the controller.

[0030] When in use, the distance between the movable bracket 4 and the retractable bottom plate 1 is adjusted according to the size of the steam turbine body 2. The retractable bottom plate 1 is an electrically retractable plate. By controlling the retractable bottom plate 1, the lateral distance of the retractable bottom plate 1 can be adjusted to suit the length of the steam turbine body 2. By driving the bidirectional motor 14 to drive the first lead screw 15 and the second lead screw 16 to rotate, the two sets of movable brackets 4 can be driven to shrink or open toward the center to suit the width of the steam turbine body 2.
