The specific embodiment
Term:
Horizontal limiting and guiding device: be used for guaranteeing that excessive horizontal translation and rotation do not take place in the basic planar central position that keeps in the boiler body course of work, vertically thermal deformation can free free device.
Embodiment:
Below will combine accompanying drawing that one preferred implementation of the utility model is elaborated, so that clearer purpose, characteristics and the advantage of understanding the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.The experimental technique of unreceipted actual conditions in the following example is usually according to the normal condition or the condition of advising according to manufacturer.
The utility model one preferred implementation and a kind of suspended boiler device.Fig. 1 is the structural representation of this device.
This kind suspended boiler device comprises:
Big plate-girder system 1, the girder construction of the arranged crosswise of furnace roof is born the boiler load that suspension rod transmits, and forms the rigid layer of furnace roof.
Horizontal limiting and guiding device is used to prevent boiler body 2 translation and rotation in the horizontal direction, and horizontal limiting and guiding device adopts damper 6, and this damper 6 is arranged between the buckstay 52 of boiler body 2 and boiler grate 5 in pairs.
Between the rigidity beam 52 of suspended boiler body 2 and boiler grate 5, set up a horizontal limiting and guiding device, this guider adopts damper 6.By the stressing device that damper 6 connects, damper 6 is set when low speed be out of shape, allows to move, locking when speed or acceleration surpass corresponding value, reliably power transmission between formation rigid support and the boiler grate 5 rigidity beams 52.This damper 6 can design according to required external force size of bearing; Making does not influence boiler body 2 thermal deformations in the transmittance process of horizontal force; Can effectively transmit horizontal forces such as wind, earthquake all the time again, can not bump, stuck etc. possibly caused the impaired situation of boiler body 2 and boiler grate 5.
Damper 6 adopts mechanical damper, spring-damper, hydraulic damper, pulse damper, rotary damper, wind damper, viscous damper or MR damper.
In addition, be appreciated that damper 6 can adopt but is not limited to the above-mentioned damper of listing.
The maximum, force that damper 6 is born is 150 tons, and the stroke of damper 6 is a 0.2-0.6 rice.
The stroke of damper 6 can design as requested, and in the large-scale thermal power occasion, the preferable stroke of damper 6 is 0.5 meter.
Damper 6 is arranged on horizontal four direction in pairs.
The paired layout of four direction can be controlled boiler body 2 stressed on horizontal all directions; When receiving wind-force or geological process; Damper 6 can balance in the external force of four direction with effect; This kind structure can be applied in the seismic environment more than 9 grades, better protect boiler body 2 and boiler grate 5.
Damper 6 in the vertical direction layered arrangement.Preferably, damper 6 in the vertical directions divide two layers of layout.
In some other embodiment of the utility model, damper 6 also can divide the design of 1-4 layer.Hierarchical design better in the vertical direction is stablized boiler body 2, reduces the impact of external force to boiler body 2 and boiler grate 5.
Damper 6 is positioned at the rigidity beam 52 absolute altitude places of boiler grate 5.
Because boiler plant adopts the suspension type design; So in the time of in being in seismic environment; The impact that the eminence of boiler body 2 and boiler grate 5 receives is greater than lower, so damper 6 is arranged on the destruction that boiler grate 5 rigidity beams 52 absolute altitude places can the better protection boiler body avoid earthquake.
In addition, being appreciated that horizontal limiting and guiding device, is damper 6 in the utility model, also can be arranged on the centre or the low side of boiler grate 5 rigidity beams 52, also can reach the effect of damping, antidetonation, and just effect is not provided with the good of absolute altitude place.
Damper 6 adopts bolt to be connected with boiler body 2; Adopt bolt to be connected between the rigidity beam 52 of damper 6 and boiler grate 5.
Bolt in the big power station field, because the volume and the quality of boiler body 2 are all very huge, needs to adopt simple and reliable connected mode to ensure the intensity and the security of connection for being rigidly connected.Certainly, in some other embodiment of the utility model, also can adopt welding to wait other modes to connect.In another preference, damper 6 adopts bolt to be connected with boiler body 2; Also adopt bolt to be connected between the rigidity beam 52 of damper 6 and boiler grate 5.
Distance between the rigidity beam 52 of steel furnace body 2 and boiler grate 5 is 0.5-1.5m.That preferable is 1-1.2m.This distance is mainly used in places damper 6, and better distance is about 1m, and the stroke of damper 6 is 0.5 meter.
Because the volume and the quality of boiler body 2 are huge, boiler grate 5 needs to adopt higher steel or the armored concrete of intensity to process.
Big plate-girder system 1 adopts the real abdomen girder steel of box-shaped superposed type, and real abdomen girder steel is processed by the steel plate welding.
The real abdomen girder steel of box-shaped superposed type cross section is box, has advantages of high strength, can satisfy the load-bearing requirement of the medium-and-large-sized boiler of large-scale thermal power technology.
Comparative Examples:
This Comparative Examples is the not preferred suspended boiler device of the utility model one, and Fig. 2 is the structural representation of this boiler plant.
This device is that with the difference of preferred suspended boiler device horizontal limiting and guiding device adopts guide post 71 to match with guide type shoe 72.Need leave certain gap between guide post 71 and the guide type shoe 72, to guarantee alignment error.
Simple, the realization easily of this kind fit system can prevent the collision and the impact of earthquake simultaneously to a certain extent.But owing to have the space between guide post 71 and the guide type shoe 72, in high earthquake intensity area, earthquake is comparatively frequent strong, and boiler body 2 can produce relative motion with boiler grate 5 under effects such as wind and seismic force, thereby bumps, and produces shock loading.Shock loading can make boiler body 2 and boiler grate 5 bump and damage.In the preference of the utility model, optimized this kind structure, with cooperating in damper generation 6 for guide post 71 and guide type shoe 72.Damper 6 can impact load cushion, offset, and has the effect of damping, energy dissipating, can be applied in seismic region more than 9 grades.
