Abstract
The utility model belongs to the technical field of a boiler economizer supporting beam and specifically relates to a slide structure for a boiler economizer supporting beam, it can solve slip group ( polytetrafluoroethylene and corrosion resistant plate ) because of the inhomogeneous problem of pressurized behind the beam deflection, its includes economizer supporting beam and girder, an economizer supporting beam lower extreme fixed connection steel sheet upper end, steel sheet lower extreme fixedly connected with corrosion resistant plate, a serial communication port, fixed mounting has the notch plate that open the upper end has the sphere recess on the girder, be provided with the convex board that the complex has the spherical surface hill in the arc recess, convex board upper end fixedly connected with polyfluortetraethylene plate, the corrosion resistant plate lower extreme support in the polyfluortetraethylene plate up end.
Description
Technical field
The utility model belongs to boiler economizer brace summer technical field, is specially a kind of sliding support structure for boiler economizer brace summer.
Background technology
The economizer backplate of part boiler tail is had to adopt Surgery therapy structure, particularly after combining with Benitration reactor at present.Backplate hangs on economizer beam, and economizer beam is heated in boiler flue, and for keeping consistent with backplate temperature, no longer ventilating and cooling, therefore, economizer beam can expand to two ends when boiler operatiopn.General economizer beam adopts supporting structure, directly rests on steelframe crossbeam, does not weld with satisfied slip requirement.
Because the coefficient of friction between steel and steel is comparatively large, larger extra force of sliding friction can be produced to economizer beam, affect the intensity of beam.Current employing modified supporting structure, increases by one group of sliding support structure between economizer beam and supporting crossbeam.As shown in Figure 1, lower steel plate 1 is welded on crossbeam 2, lower steel plate 1 opens inside groove inlaid polytetrafluoroethylsliders plate 3, economizer brace summer 4 puts (welding) on steel plate 5, steel plate 5 times welding one piece of thin corrosion resistant plate 6, because corrosion resistant plate 6 and polyfluortetraethylene plate 3 coefficient of friction very little, total relies on contact surface between the two to realize the transmission of load and interstructural slip.
The compressive resistance of polyfluortetraethylene plate 3 is 6.4Mpa, and far below the compressive resistance (325Mpa) of general steel plate, the load according to economizer brace summer 4 end calculates the area determining polyfluortetraethylene plate.
Economizer brace summer 4 itself needs the load bearing economizer piping, also has the load of economizer backplate, can occur normal bending after economizer brace summer 4 stand under load, end produces certain corner, corrosion resistant plate 6 and polyfluortetraethylene plate 3 will be made to be contacted by original face and to change linear contact lay into, greatly reduce the loaded area of polyfluortetraethylene plate 3, the pressure of local polyfluortetraethylene plate 3 is made to exceed tolerance zone, produce plastic deformation, progressively expand to whole working face, so greatly improve coefficient of friction, change the original intention of this structure, the cracked inefficacy of whole polyfluortetraethylene plate 3 can be made time serious.
Summary of the invention
In order to solve the problem, the utility model provides a kind of sliding support structure for boiler economizer brace summer, and it can solve Slide Group (polytetrafluoroethylene (PTFE) and corrosion resistant plate) because of the uneven problem of pressurized after beam deflection.
Its technical scheme is such: a kind of sliding support structure for boiler economizer brace summer, it comprises economizer brace summer and crossbeam, fixing connection steel plate upper end, described economizer brace summer lower end, described steel plate lower end is fixedly connected with corrosion resistant plate, it is characterized in that, described crossbeam is installed with the notch plate that upper end has spherical groove, the convex plate with spherical surface hill of cooperation is provided with in described arc groove, described convex plate upper end is fixedly connected with polyfluortetraethylene plate, and described corrosion resistant plate lower end is supported in described polyfluortetraethylene plate upper surface.
It is further characterized in that, has discharging opening bottom the spherical groove of described notch plate;
The surface roughness of the contact surface of described notch plate and described convex plate is 6.3.
After adopting structure of the present utility model, adopt the combination of the notch plate with spherical groove and the convex plate with spherical surface hill, form rotating universal structure form, solve Slide Group (polytetrafluoroethylene (PTFE) and corrosion resistant plate) because of the uneven problem of pressurized after beam deflection.

Fig. 2 is the utility model structural representation;
Fig. 3 is economizer brace summer stand under load schematic diagram when bending.
Detailed description of the invention
See Fig. 2, shown in Fig. 3, a kind of sliding support structure for boiler economizer brace summer, it comprises economizer brace summer 4 and crossbeam 2, welding steel 5 upper end is fixed in economizer brace summer 4 lower end, steel plate 5 lower end is fixedly welded with corrosion resistant plate 6, crossbeam 1 is installed with the notch plate 7 that upper end has spherical groove, the convex plate 8 with spherical surface hill of cooperation is provided with in arc groove, convex plate 8 upper end is fixedly connected with polyfluortetraethylene plate 3, corrosion resistant plate 6 lower end is supported in polyfluortetraethylene plate 3 upper surface, when bight after economizer brace summer 4 stand under load produces corner, at this moment notch plate 7 and convex plate 8 produce relative rotation, corrosion resistant plate 6 and polyfluortetraethylene plate 3 are still the complete contact condition in front, the problem changing linear contact lay into can not be contacted by face, having discharging opening 9 bottom the spherical groove of notch plate 7, for collecting the iron filings rotating and produce, to reduce rotary resistance, preventing bite, notch plate 7 is 6.3 with the surface roughness of the contact surface of convex plate 8, ensures to relatively rotate.
