Description
Technical field
The utility model belongs to hydraulic turbine field, especially relates to a kind of floating connecting structure for hydraulic generator upper bracket and out frame.
Background technology
The upper bracket of hydraulic generator is contained in the upside of out frame.Operationally, stator core and out frame all can expand because being heated hydraulic generator, and upper bracket is in the relatively low region of temperature, and heat rises very little.In traditional design; upper bracket adopts with out frame and is fixedly connected with; this kind of method has the following disadvantages: stator core and out frame expanded by heating after generator operation; but owing to being subject to the constraint of the upper bracket be fixedly linked with out frame; stator core and support is caused freely swollenly to rise and contraction after shutting down; cause stator core easily buckling deformation to occur after reciprocation cycle of expanding with heat and contract with cold after generator long-time running, stator core loosening will be caused time serious, bar insulation is impaired and cause the major accidents such as short circuit.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art, there is provided a kind of structure simple, floating connecting structure easily for hydraulic generator upper bracket and out frame is installed, it achieves between upper bracket and out frame and can freely move radially, positioning requirements between the two can be met, both thermal deformation requirements can be adapted to again.
To achieve these goals, the utility model by the following technical solutions: a kind of floating connecting structure for hydraulic generator upper bracket and out frame, comprises
Chute, is located on described out frame;
Slide block, its top and described upper bracket are connected, and its underpart is provided with the sliding surface coordinated with described slide, are provided with gap between bottom its bottom and chute;
The sleeve pipe of inner hollow, its outer wall and described upper bracket are connected;
Bolt block, its lower end and out frame are connected;
Bolt, for connecting upper bracket and out frame, its underpart is connected with described bolt sleeve through sleeve pipe, is provided with gap between bolt outer wall and internal surface of sleeve pipe; Gap is provided with between bolt upper end and its lower end portion;
This structure makes upper bracket be connected for floating connection with out frame, and by coordinating between the slide block on upper bracket and the chute on out frame, the slide block that can carry out on the upper bracket of circumference location can along radially moving in the chute on out frame; Upper bracket and out frame can be connected by bolt, and for pine is connected between bolt with sleeve pipe, rely on and radially move with the gap in sleeve pipe; Efficiently solve the thermal deformation that expanded by heating unshakable in one's determination causes, and solve out frame in the affined restriction of radial direction, thus substantially increase the reliability that hydraulic generator normally works, reduce the difficulty of mounting and adjusting, also improve operating efficiency.
As preferably, described upper bracket corresponds to described bolt upper end and be provided with a scotch.
Further, described upper bracket is provided with the block for limiting the excessive movement of chute, and upper end and the upper bracket of this block are connected, and lower end corresponds to described chute outer wall and arranges; By the setting of block, local contraction amount can be prevented excessive, upper bracket center and initial condition are consistent.
Further, pluggable adjustment distance piece is provided with between bottom described slide block and chute.
Pluggable adjustment distance piece is provided with between described sleeve pipe and bolt block.
In sum, the utility model has the following advantages: the utility model structure is simple, and fitting operation is convenient, effectively shortens project man-hour; Move radially by slide block and bolt the thermal deformation adapting to stator core expanded by heating and cause, efficiently solve support in the affined restriction of radial direction, thus substantially increase the reliability that hydraulic generator normally works.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cross section view of Fig. 1.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.
As shown in Figure 1, 2, a kind of floating connecting structure for hydraulic generator upper bracket and out frame, comprises
Chute 3, if be welded on described out frame 8;
Slide block 1, in the present embodiment, this slide block is cylindrical, its underpart mills out two smooth flat, form the sliding surface 11 coordinated with described slide, slide block 1 can move radially in chute, and can carry out circumference location, concrete, slide block 1 upper end is welded with upper bracket 9, loads adjustment distance piece 4, taken away by adjustment distance piece 4 after having welded before welding, ensure that slide block does not directly contact in the vertical direction with chute, between namely bottom slide block bottom and chute, be provided with gap; Obviously, described slide block 1 may not be cylindrical or square type, and cross sectional shape can be irregularly shaped, but must ensure that slide block 1 is smooth flat with chute contact-making surface in chute 2, can move radially.The welding position of slide block 1 is undressed end and upper bracket does not limit, and can penetrate upper bracket-arm welding, also can directly be welded on upper bracket lower surface; Sleeve pipe 7, its inner hollow, can pass for bolt, its outer wall and described upper bracket are connected;
Bolt block 10, its lower end and out frame are connected, in the present embodiment, bolt block by welding mode and out frame realize being connected;
Bolt 6, for connecting upper bracket and out frame, its underpart is connected with described bolt sleeve through sleeve pipe 7, is provided with gap between bolt outer wall and internal surface of sleeve pipe; Gap is provided with, in the present embodiment, before welding, by arranging pluggable adjustment distance piece 8 between described sleeve pipe 7 and bolt block, to form described gap, for finely tuning upper bracket level and center between bolt upper end and its lower end portion;
When stator core expanded by heating, out frame radial direction swells, chute 3 radially can move along the machined surface of slide block 1, simultaneously, bolt 6 and bolt block 10 can rely on the gap in casing seat 7 radially to be moved, and the movement that upper bracket is relative can not be caused, ensure that out frame adapts to stator core and to expand the thermal deformation caused.
