Background technology
Along with the development of State Grid's industry, the single-machine capacity of Turbo-generator Set is increasing, and the thermal power plant of 600MW unit has become thermal power plant of the main force, and constantly increases more than thermal power plant's quantity of 1000MW capacity.The increase of single-machine capacity, not only makes main building in plane, spatially all must increase to meet technological requirement, and has had the model of auxiliary power machine and power requirement and further promote.This just makes the dynamic action problem of auxiliary power machine become more outstanding, thus the load-bearing situation that result in its basis becomes increasingly complex.
At present, the based process method of steam power station auxiliary machinery generally adopts amplitude control method and vibrations removing method: the former process often adopts mass foundation and FRAME FOUNDATION, take appropriate measures in the design stage and carry out amplitude controlling in advance, the dynamic effect not making power machine produce reduces, and design in advance likely exists gap compared with Practical Project, the shake control object not reaching expection will be caused; And the process of the latter often needs the pedestal of enough large rigidity and quality, not only bring inconvenience to construction, and substantially increase the cost on basis.
Utility model content
In view of the deficiency of existing damping treatment technology; the purpose of this utility model is to provide a kind of steam power station power machine shock insulation backing plate; both can reduce steam power station power-assisted machine to its basis and the dynamic action of mill construction or component under the prerequisite not increasing cost, and can under adverse circumstances load, protect power machine normally to work again or not by larger damage.
To achieve these goals, the technical solution of the utility model is: a kind of steam power station power machine shock insulation backing plate, comprise the steel structure upper plate and steel structure lower plate that are oppositely arranged up and down, be provided with flexible unit between described steel structure upper plate and steel structure lower plate, described flexible unit comprises rubber cushion blocks and spring.
Further, the first groove of opening upwards is offered in the middle part of described steel structure lower plate, the boss stretched in the first groove is provided with in the middle part of described steel structure upper plate, the second groove that Open Side Down is offered in the middle part of described boss, described rubber cushion blocks is arranged between boss bottom surface and the first groove floor, and described spring is arranged between the second groove floor and the first groove floor.
Further, under described steel structure, panel edges evenly offers the 3rd groove of opening upwards, cushion rubber layer is provided with in described 3rd groove, described steel structure upper board edge evenly offers the 4th groove that Open Side Down, described 4th groove internal fixtion has vertical backstay, and described vertical backstay lower end is inserted in cushion rubber layer.
Further, the described spring groups of springs that is single spring or is made up of multiple spring.
Compared with prior art, the utility model has the following advantages: (1) can reduce steam power station auxiliary power machine effectively to the dynamic action on basis, and can effectively protect surrounding buildings or instrument normally to work; (2) power-assisted machine effectively can be protected under the adverse circumstances load actions such as earthquake normally to work or not be subject to larger damage; (3) compared with existing isolation measure, cost can be reduced significantly; (4) can make to measure according to the basic parameter of power-assisted machine, can factorial praluction be realized, thus shorten the cycle put into production use; (5) in addition, namely given a piece of bad advice, also can change, and picture maintenance or basic so high expense of reforming can not have been produced.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the organigram of the utility model embodiment.
In figure: 1-steel structure upper plate, 11-boss, 12-second groove, 13-the 4th groove, 2-steel structure lower plate, 21-first groove, 22-the 3rd groove, 3-rubber cushion blocks, 4-spring, the vertical backstay of 5-, 6-cushion rubber layer.
Detailed description of the invention
As shown in Figure 1, a kind of steam power station power machine shock insulation backing plate, comprise the steel structure upper plate 1 and steel structure lower plate 2 that are oppositely arranged up and down, be provided with flexible unit between described steel structure upper plate 1 and steel structure lower plate 2, described flexible unit comprises rubber cushion blocks 3 and spring 4.
In the present embodiment, the first groove 21 of opening upwards is offered in the middle part of described steel structure lower plate 2, the boss 11 stretched in the first groove 21 is provided with in the middle part of described steel structure upper plate 1, the second groove 12 that Open Side Down is offered in the middle part of described boss 11, described rubber cushion blocks 3 is arranged between boss 11 bottom surface and the first groove 21 bottom surface, described spring 4 is arranged between the second groove 12 bottom surface and the first groove 21 bottom surface, the groups of springs that described spring 4 can be single spring 4 or be made up of multiple spring 4.Under the dynamic load function of steam power station auxiliary power machine, there is elastic deformation in described rubber cushion blocks 3 and spring 4, thus effectively consume dynamic loading to its basis and the shock effect of mill construction or component.
In the present embodiment, described steel structure lower plate 2 edge evenly offers the 3rd groove 22 of opening upwards, cushion rubber layer 6 is provided with in described 3rd groove 22, described steel structure upper plate 1 edge evenly offers the 4th groove 13 that Open Side Down, described 4th groove 13 internal fixtion has vertical backstay 5, and described vertical backstay 5 lower end is inserted in cushion rubber layer 6.Under the dynamic load function of steam power station auxiliary power machine, described vertical backstay 5 can control the shear strain of shock insulation backing plate under dynamic load function effectively.
In the present embodiment, described steel structure upper plate 1 and steel structure lower plate 2 should meet the strength and stiffness requirement under auxiliary machinery dynamic load function, specifically should determine by calculating according to actual loading situation; The rigidity of described flexible unit and damping are determined by simple substance point system computing by the isolation efficiency of actual dynamic loading and expection.
For steam power station auxiliary machinery power water feeding pump, power water feeding pump size type and basic parameter are determined by the technological requirement of power plant, can be determined the overall size of the upper and lower plate of steel structure by the basic parameter of power water feeding pump; The sectional dimension of the upper and lower plate of steel structure is required to determine by calculating by strength and stiffness, steel structure lower plate 2 is pressed compressed member and is considered, steel structure upper plate 1 is pressed simple flexural member and is considered, load is multiplied by the coefficient of impact and calculates by static problem, is completed after cross section is selected by factory process manufacture; Calculated with simple substance point vibration-isolating system by the kinetic parameter of power water feeding pump and the isolation efficiency of expection again, the simple harmonic motion equation with simple substance point system:
