Abstract

The utility model discloses a chimney damper for reducing the vibration of a chimney. The chimney damper comprises at least three cantilevers fixed on the outer wall of the chimney; the cantilevers are connected with an annular quality loop through hanger rods; at least three hydraulic rods are uniformly distributed on the annular quality loop; one end of each hydraulic rod is connected with the annular quality loop; the other end of the hydraulic rod is connected with and fixed to a piece of cantilever angle iron on the outer wall of the chimney; and universal joints are arranged between the hanger rods and the quality loop and between the hanger rods and the cantilevers. The chimney damper has a simple structure, is economical, can reduce the chimney the amplitude of vibration of the chimney caused under the action of wind load and earthquake load, and reduces the displacement of the top of the chimney, so that the structural global stress of the chimney can be reduced, the structural design of the chimney can be improved, and the chimney is enabled to be more economical and safer and have a wide development potentiality.

Description

The chimney damper
Technical field
the utility model relates to a kind of vibration absorber, refers more particularly to the vibration absorber that on chimney structure, uses.
Background technology
<b >chimney structure belongs to tall and slender structure, and it has the characteristics of Gao Rou, and especially to steel stack, this just means that its natural vibration period is bigger, and top displacement is big, serious vibration.In order to increase Stability Analysis of Structures, generally take auxiliary support structures such as drag-line, pylon, perhaps increase self cross section, it can be supported oneself.<<Yan Congshejiguifan>>Its ratio of height to diameter of regulation free-standing steel chimney must not be greater than 20 in the GB50051-2002.</b>
in recent years; Because the steel stack lot of advantages, use steel stack to replace traditional brick chimney and reinforced concrete chimney in the domestic beginning on a large scale, but can't do at present too high;, mainly be exactly generally owing to its vibration cause below 100 meters high.
therefore press for a kind of effective chimney vibration-proof structure of utility model very much.
Summary of the invention
the utility model technical problem to be solved is to provide a kind of chimney damper that alleviates the chimney vibration.
In order to solve above-mentioned technical problem, the technical scheme that the utility model adopts is: the chimney damper, it is characterized in that it comprises at least three cantilevers that are fixed on the chimney outer wall, and said cantilever connects an annular quality loop through suspending rod;
Be evenly distributed to few three hydraulic stems on the said annular quality loop, said hydraulic stem one end is connected on the said annular quality loop, and the other end is fastened on the cantilever angle steel on the chimney outer wall;
Be provided with universal joint between said suspending rod and the quality loop, be provided with universal joint between said suspending rod and the cantilever.
preferably, there is 5-10 degree horizontal sextant angle on said hydraulic stem and quality loop plane.
preferably, said hydraulic stem and quality loop plane have 5 the degree horizontal sextant angles.
preferably, the inboard evenly distributive plural damping rubber block of said annular quality loop.
preferably, said chimney damper also comprises an annular outer cover.
preferably, said quality loop quality is 5% ~ 20% of a chimney quality.
preferably, the distance between said quality loop and the annular outer cover is 100mm-200mm.
preferably, the distance between said damping rubber block and the chimney outer wall is 150mm.
preferably, said chimney damper is located near position tip position or the top of chimney.
are scope circumference sprung mass ring in the chimney top, and hydraulic stem is installed, and makes itself and quality loop hinged.Because quality loop is asynchronous with chimney self vibration, produces delay, therefore, during the chimney vibration, quality loop produces rightabout active force through hydraulic stem to chimney, hinders the chimney vibration, has played damping effect.
The concrete advantage and the characteristics of chimney damper are following: the chimney damper structure of the utility model is simple; Economy can reduce chimney at wind load, seismic loading lower stack Oscillation Amplitude, reduces the chimney top displacement; Thereby it is stressed to reduce chimney structure integral body; Can improve the chimney structure design, make chimney more economical, safer, wide development potentiality is arranged.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the chimney damper plan structure sketch map of the utility model.
Fig. 2 is the chimney damper side structure sketch map of the utility model.
wherein, 1 is cantilever, 2 is suspending rod, 3 is quality loop, 4 is universal joint, 5 is hydraulic stem, 6 is the cantilever angle steel, 7 is damping rubber block, 8 is annular outer cover, 9 is the chimney outer wall.
The specific embodiment
further specify such scheme below in conjunction with specific embodiment.Should be understood that these embodiment are used to the utility model is described and the scope that is not limited to limit the utility model.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.
like Fig. 1, shown in Figure 2, the chimney damper, and it comprises at least three cantilevers 1 that are fixed on chimney outer wall 9, cantilever 1 connects an annular quality loop 3 through suspending rod 2; Even six hydraulic stems 5 that distribute on the said annular quality loop 3, said hydraulic stem 5 one ends are connected on the said annular quality loop 3, and the other end of hydraulic stem 5 is fastened on the cantilever angle steel 6 on the chimney outer wall 9; Be provided with universal joint 4 between said suspending rod 2 and the quality loop 3, and also be provided with universal joint 4 between suspending rod 2 and the cantilever 1.Like this, quality loop 3 freely is connected with chimney, does not form the rigid unitary structure.Therefore, during the chimney vibration, quality loop 3 produces rightabout active force through 5 pairs of chimneys of hydraulic stem, hinders the chimney vibration, has played damping effect.
in the preferred embodiment of the utility model, hydraulic stem 5 has 5-10 degree horizontal sextant angle approximately with quality loop 3 planes, is preferably 5 degree horizontal sextant angles.When chimney vibrated, because the delay of quality loop 3 vibration, the cantilever lever 2 of sprung mass ring 3 can produce little angle with the chimney axis; It is small in top offset to make quality loop 3 have; So just make hydraulic stem 5 produce compression, thereby chimney is produced reaction force, hinder the chimney vibration.Said annular quality loop 3 inboard six damping rubber blocks 7 that evenly distribute, when preventing quality loop 3 work to the bump of chimney wall.
are in the another preferred embodiment of the utility model; Said chimney damper also comprises an annular outer cover; Use the annular outer cover cover that above structural defence is got up; Consider that hydraulic stem needs to change (general about 3 years) after using certain hour, near hydraulic stem position on the jacket, offer six access doors.
in the another preferred embodiment of the utility model, said quality loop is 5% ~ 20% of a chimney quality, and the distance between said quality loop and chimney outer wall and the annular outer cover is generally about 100-200mm, is preferably 150mm.And the chimney damper of the utility model is located at the tip position of chimney or near the position the top, can play cushioning effect better.
above-mentioned instance is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the people who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalent transformation or modifications of being done according to the utility model spirit all should be encompassed within the protection domain of the utility model.
