Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical scheme of this utility model embodiment is carried out clear, complete description.
A kind of ring-shaped liquid antivibrator that this utility model is disclosed, is mainly used in towering steel stacks structural damping use, solves the impulse oscillation that produces due to transverse direction and the vertical wind destruction to steel chimney structure.Certainly, except being applied to towering steel stacks, it is possible to applying other main structures needing damping, this utility model does not limit, structure and the operation principle of this utility model ring-shaped liquid antivibrator are specifically introduced being applied to steel chimney structure below.
As shown in Figure 2, a kind of ring-shaped liquid antivibrator that this utility model is disclosed, including at least two-layer ring-shaped liquid damper body, ring-shaped liquid damper body is fixed on steel stack 1 outer wall and connects up and down between them, every layer of ring-shaped liquid damper body is made up of one or more water tanks 2, it is fixed on the outer wall of steel stack inside water tank, and is connected by corresponding location structure between upper and lower two adjacent water tanks, as the present embodiment adopts location-plate 4 to connect.Wherein, the number of plies of ring-shaped liquid damper body carries out relative set according to the Force Calculation of steel chimney structure.
When specifically installing, first one or more water tanks are weldingly fixed on the position bottom steel stack main structure according to same level height, form the ring-shaped liquid damper body of the bottom, then according to calculating the required number of plies, above bottom water tank, being sequentially connected in series the 2nd layer ... n-th layer water tank, wherein N is be more than or equal to 2, and is connected on steel stack by upper and lower two water tanks by location-plate.
So, compared with existing the structure that one layer of ring-shaped liquid damper body is set, the structural design of the multi-layer annular liquid condenser body connected up and down of the present utility model, on the one hand because adding the weight that antivibrator is overall, thus adding the integral damping ratio of steel stack main structure so that this utility model can apply to the steel stack vibration damping of more than 25m；On the other hand, single water tank when mounted or is lifted by crane and is installed on chimney by this utility model, increased the volume and weight of antivibrator by the mode connected up and down, with existing directly by increase the water tank integral installation after volume to chimney compared with, it is simple to lifting and installing.
It addition, in order to meet the optimum damping ratio requirement required for steel chimney structure further, as it is shown on figure 3, each water tank 2 of this utility model includes casing 5, horizontal damping net 6 and vertical damping screen 7, casing is generally enclosed, and casing 5 is built with tuning liquid 3.Horizontal damping net 6 is fixed on the medial wall of casing, for increasing the damping of liquid in the vertical direction；Box bottom is fixed in vertical damping screen 7 one end, and the other end and horizontal damping net are fixed, for increasing liquid damping in the horizontal direction.In this utility model, the cross section of casing is annular, and horizontally and vertically damping screen is also annular accordingly.
During installation, vertical damping screen 7 is welded on box bottom, then horizontal damping net 6 is welded on the sidewall of casing left and right, and spot-welded together with vertical damping screen 7, finally press the design-calculated depth of water in casing, inject tuning liquid 3.When being embodied as, tuning liquid can adopt ZnSO4The mixed liquor of liquid or water and anti-icing fluid, the liquid certainly used in other existing TLD is applied equally to this utility model.
Preferably, horizontal damping net 6 level is fixed on the box inside wall At The Height less than tuning liquid depth half, and namely if the liquid depth in casing is 1m, then horizontal damping net is preferably secured to the box inside wall At The Height less than 0.5m.When horizontal damping net 6 is arranged on the At The Height equal to liquid depth half in fact, liquid in the vertical direction can obtain the highest damping, but it is because the marginal value that this is an imagination, can not reach during actual enforcement, so horizontal damping net 6 is arranged the closer to the At The Height of liquid depth half, the damping on its obtainable vertical direction is more big.
Preferably, vertical damping screen 7 is vertically fixed on the middle position close to or at box bottom, namely if the width of box bottom is 1m, then vertically one end of damping screen 7 be fixed on box bottom near or be placed exactly in the position of its 0.5m width.When vertical damping screen 7 is vertically fixed on the middle position of box bottom, liquid can obtain the highest damping in the horizontal direction, and therefore, vertical damping screen 7 is the closer to the middle position of box bottom, and the damping in its obtainable horizontal direction is more big.When being embodied as, horizontally and vertically damping screen can use grid.
Being distributed with multiple mesh on HORIZONTAL PLAID aperture plate 6 and vertical grid 7, the specification of mesh is configured in combinations with the many kinds of parameters such as specification of actual steel chimney structure, and this utility model does not limit, and uses adapting to various steel chimney structure damping.The shape of mesh can also be various, as being circular, the enforcement data of present stage shows, the diameter of circular mesh is traditionally arranged to be 5～20mm.Being alternatively square or other are regular or irregularly shaped, square grid hole size is generally 5mm × 5mm～20mm × 20mm, and the size of certain mesh is not limited to mentioned here, can be determined according to actual needs.
This utility model passes through the combination of horizontally and vertically damping screen in casing, have adjusted the liquid degree of depth in casing, adds the damping ratio of TLD.When steel stack main structure is vibrated by external wind excitation, cause rocking of liquid in water tank, liquid is by the hole dissipation power potential energy of HORIZONTAL PLAID aperture plate and vertical grid, add the damping ratio of TLD, make the dynamic pressure difference of TLD tank wall and the increase of making a concerted effort of liquid inertia power, steel stack main structure obtains in opposite direction with structural vibration and acts on the power that main structure is bigger, the dynamic respons making main structure is decayed and is controlled, it is hereby achieved that the optimum damping ratio requirement required for steel chimney structure.
Technology contents of the present utility model and technical characteristic have revealed that as above; but those of ordinary skill in the art are still potentially based on teaching of the present utility model and announcement and do all replacements without departing substantially from this utility model spirit and modification; therefore; this utility model protection domain should be not limited to the content that embodiment is disclosed; and should include various without departing substantially from replacement of the present utility model and modification, and contained by present patent application claim.
