Abstract
The utility model discloses a radiation-type tangential force rack structure, which consists of a central body, supporting arms and connecting beams among the supporting arms. The connecting beams among the radiation-type supporting arms enhance the torsion rigidity of a rack. Convex keys at the end parts of the supporting arms are in close fit with key slots on embedded parts which are embedded in a concrete pit. Thermal expansion gaps for the supporting arms are left in a radial direction. Therefore, radial force which acts on the rack can be converted into tangential force which acts on concrete.
Description
Technical field: the utility model relates to a radial pattern tangential force rack construction.
Background technique: the hydraulic turbine generator frame is generally radial pattern at present, and the support arm end does not have protruding key, is provided with the jack of a dish spring structure between support arm and machine hole, does not have tie-beam between each support arm.The frame shortcoming of this kind structure is, jack and support arm are for dividing a body structure, and bad to neutrality with support arm, the rigidity of jack has multi-disc dish spring to provide in addition, and radial height is low.Each arm room does not arrange a little less than tie-beam so the torsional stiffness in addition.Therefore need a kind of radial rigidity height of research, can adapt to the new frame of support arm thermal expansion simultaneously.
Summary of the invention: the purpose of this utility model provides a kind of hydraulic turbine generator radial pattern tangential force frame simple in structure, reliable performance.The technical solution of the utility model is:
A kind of radial pattern tangential force rack construction is welded by centerbody (1), radial pattern support arm (2) and arm room tie-beam (3); Centerbody (1) is by last plectane (4), following plectane (5), and oil groove wall (6), seat ring (7), stud (8) is welded; Support arm (2) is by upper flange (9), lower wing plate (10), and protruding key (11), gusset (12) is welded.Keyway side direction on protruding key (11) on the frame support arm and concrete embedded (12) is that drive fit radially is big gap.
Described radial pattern tangential force frame is provided with tie-beam (3) between each radial pattern support arm (2), has increased the rigidity of frame.
The radial force that acts on the frame can be converted into the tangential force that acts on the concrete foundation in the time of the frame accommodate thermal expansion.Can guarantee when heat expansion can be adapted to, to increase the radial rigidity of frame
Adopt the hydraulic turbine generator of this kind structure frame, because radial pattern support arm (2) directly is connected with the concrete mixer hole, can with the direct place of production of the power on the frame to concrete, can reduce the upper spider vibration amplitude improving upper spider rigidity; Simultaneously can adapt to frame heat and rise, avoid the concrete mixer hole is damaged.

Embodiment:
A kind of radial pattern tangential force frame as shown in Figure 1 and Figure 2 is welded by centerbody 1, radial pattern support arm 2 and arm room tie-beam 3; Centerbody 1 is by last plectane 4 as shown in Figure 3, following plectane 5, and oil groove wall 6, seat ring 7, stud 8 is welded; Support arm 2 is by upper flange 9 as shown in Figure 4, lower wing plate 10, and protruding key 11, gusset 12 is welded.Protruding key 11 on the frame support arm is that drive fit radially is big gap with the keyway side direction on concrete embedded 12.
Radial pattern tangential force rack construction as shown in Figure 1 and Figure 2 is provided with tie-beam 3 between each radial pattern support arm 2, has increased the rigidity of frame.
Described a kind of radial pattern tangential force rack construction as shown in Figure 5, the protruding key 11 on the frame support arm is that drive fit radially is big gap with the keyway side direction on concrete embedded 12.The radial force that acts on the frame can be converted into the tangential force that acts on the concrete foundation in the time of the frame accommodate thermal expansion.Can guarantee when heat expansion can be adapted to, to increase the radial rigidity of frame.
By centerbody, support arm, tie-beam are joined according to physical location in the building site and are welded into integral body.
Keyway side direction between the terminal protruding key of support arm and the concrete embedded part is drive fit, it radially is big gap, namely can accommodate thermal expansion, avoiding heat expansion power that the concrete mixer hole is caused brokenly changes, do the radial force that is used on the frame simultaneously and can be converted to the tangential force that acts on the basis by this structure, compare radial rigidity with conventional radial pattern frame and greatly increase.
Strengthened housing rigidity by the integrity that is welded to connect beam and has increased each support arm between each support arm.
Claims (2)
1. a radial pattern tangential force rack construction is characterized in that: be welded by centerbody (1), radial pattern support arm (2) and arm room tie-beam (3); Centerbody (1) is by last plectane (4), following plectane (5), and oil groove wall (6), seat ring (7), stud (8) is welded; Support arm (2) is by upper flange (9), lower wing plate (10), and protruding key (11), gusset (12) is welded, and the protruding key (11) on the frame support arm is that drive fit radially is big gap with keyway side direction on concrete embedded (12).
