Rubber plinth supports the steel coal hopper system
Technical field
The utility model relates to steel coal hopper, especially relates to the steel coal hopper that a kind of rubber plinth supports.
Background technology
Coal bunker is the structure of storing coal in the coal-burning power plant, is usually located in the main building bunker bay framework, since circular stressed reasonable, so coal bunker mostly adopts steel circle storehouse.For the 600MW fired power generating unit of present main flow, the weight of each coal bunker is about 800 tons, and every unit has 6 coal bunkers approximately, and the weight of coal bunker and coal just has several kilotons like this.According to the technology arrangement requirement, the weight supporting of these several kilotons is on the high floor of 30~40m, the weight of coal bunker part is that main building bunker bay framework bears maximum load, the loaded center of gravity height, strong reaction during earthquake, studies show that simultaneously coal bunker support place also is the weak location of main building structural seismic.Because the geological process that causes of coal bunker weight, the beam column section of main building bunker bay is all bigger in order to resist, and what reduced process equipment greatly effectively utilizes the space, has improved construction costs.
The utility model content
The purpose of this utility model provides a kind of rubber plinth that reduces geological process and supports the steel coal hopper system, to save building materials, reduces construction investment.
For achieving the above object, the utility model provides a kind of rubber plinth to support the steel coal hopper system, comprise main building bunker bay framework, coal bunker part, it is characterized in that: the coal bunker part is made of steel coal hopper, laminated rubber bases, horizontal inhibiting device, steel coal hopper is supported on the floor beam by laminated rubber bases, and horizontal inhibiting device is arranged on the center-of-gravity position of steel coal hopper.
Horizontal inhibiting device is connected in sequence by pin hinge, reinforcing pull rod, damping spring, and horizontal inhibiting device is rotationally connected by the horizontal stiffness ring beam of pin hinge with main building bunker bay frame column and the steel coal hopper outside.
The utility model steel coal hopper directly adopts laminated rubber bases to be supported on the floor beam, and connecting joint are simple, and it is very convenient to construct.Because laminated rubber bases has the characteristic of low-level rigidity, high vertical rigidity, so the geological process that coal bunker suffers will reduce, and the geological process that suffers of supporting frame structure also can reduce simultaneously.For 8 degree (0.20g) areas, to compare with conventional coal bunker, the section of frame column can reduce 10% approximately, and the arrangement of reinforcement of beam column also can correspondingly reduce.The earthquake intensity difference, the value difference that reduces, but generally speaking can reach and reduces section, saves the purpose of building materials.Because reducing of member section, what increased process equipment effectively utilizes the space, also reduces the measure cost of construction simultaneously, and its overall economic efficiency is considerable.

The specific embodiment
With reference to Fig. 1, the utility model comprises main building bunker bay frame column 1, main building bunker bay Vierendeel girder 2, steel coal hopper 3, laminated rubber bases 4 and the horizontal inhibiting device of being made up of pin hinge 5, damping spring 6, reinforcing pull rod 7.At first laminated rubber bases 4 is supported on the framed structure of being made up of main building bunker bay frame column 1 and main building bunker bay Vierendeel girder 2, steel coal hopper 3 can be made at the scene, is welded to connect, and is lifted on the laminated rubber bases 4.Reinforcing pull rod 7 links together by the horizontal stiffness ring beam 8 of pin hinge 5 with main building bunker bay frame column 1 and steel coal hopper 3 outsides, and pin hinge 5 can be rotated, and the medium position of reinforcing pull rod 7 arranges damping spring 6.Steel coal hopper just is installed on the laminated rubber bases very easily like this.
With reference to Fig. 2, the 1st, main building bunker bay frame column, the 2nd, main building bunker bay Vierendeel girder, the 3rd, steel coal hopper, the 5th, pin hinge, the 6th, damping spring, the 7th, reinforcing pull rod, the 8th, horizontal stiffness ring beam.
With reference to Fig. 3, the 1st, main building bunker bay frame column, the 2nd, main building bunker bay Vierendeel girder, the 3rd, steel coal hopper, the 4th, rubber plinth.
