(3) summary of the invention
The purpose of this utility model is to provide a kind of direct air-cooling turbine steam exhaust device bottom supporting position structure, this supporting position structure can bear power (moment) and distortion and the displacement that various situation produces, thereby steam exhaust device is reduced in the scope of permission the influence of steam turbine, guarantee the operation of steamer function long-term safety ground.
The utility model is achieved in that a kind of direct air-cooling turbine steam exhaust device bottom supporting position structure, comprise several rigid support seats, the rigid support seat evenly distributes and is fixed on the steam exhaust device base plate, it is characterized in that described supporting position structure also comprises several fixed plates, fixed plate places on the base plate surrounding, fixed plate comprises fixed block, matrix plate and regulator plate, fixed block places in the pit of matrix plate, regulator plate places in the gap of fixed block and matrix plate and is fixed on the matrix plate, fixed block and ground are affixed, matrix plate and base plate are affixed, and regulator plate is the L template; Have screw on the rigid support seat, screwhole diameter is greater than the diameter of bolt.
Above-mentioned direct air-cooling turbine steam exhaust device bottom supporting position structure, described fixed plate is four, be distributed on the base plate surrounding, two relative edges' fixed plate places on the base plate transversal line, and two relative edges' fixed plate slightly departs from longitudinal axis but be parallel with longitudinal axis in addition.
Above-mentioned direct air-cooling turbine steam exhaust device bottom supporting position structure, described rigid support seat is made up of cladding plate and supporting base base plate, cladding plate and supporting base base plate are connected by gusset in length and breadth, and cladding plate is connected with the steam exhaust device base plate, and the supporting base base plate is connected with ground.The rigid support seat is eight, and four are positioned on four angles of base plate, and in addition four are positioned at the distribution that assumes diamond in shape of base plate middle part.
The utility model is to be the rigid support seat of symmetrical distribution and at base plate surrounding mounting plate by affixed on the steam exhaust device base plate, the rigid support seat is located on the ground, the screwhole diameter of rigid support seat is much larger than the diameter of bolt, therefore be connected the back fixes in Vertical direction and ground with ground, substantially horizontal is removable, has guaranteed that steam exhaust device can free expansion and distortion when being heated and be subjected to vacuum force.Regulator plate in the fixed plate can remedy the sum of errors distortion that steam exhaust device is produced in the on-the-spot splicing in power station installation process.The intersection point of four fixed plate center lines forms the dead point, make steam exhaust device can bear very big thrust and moment of torsion, and the dead center position of steam exhaust device remains on the constant position and is consistent with the dead center position of turbine low pressure cylinder, thereby the influence when steam turbine is moved under different operating conditionss all can be guaranteed the operation of steamer function long-term safety in the scope of permission.
Supporting position structure of the present utility model can bear the power that effect produced (moment) and the distortion and the displacement of various complexity and unfavorable factor, steam exhaust device is reduced in the scope of permission the influence of steam turbine, overcome original steam exhaust device distortion situation complexity, the relatively poor defective of reliability, guaranteed that steam turbine reaches the operation of long-term safety ground.
