Abstract
The invention belongs to the technical field of economizer supporting beams of boilers, particularly discloses a sliding bearing structure for an economizer supporting beam of a boiler and can solve the problem that a sliding group (polytetrafluoroethylene and stainless steel plates) is pressed unevenly due to beam bending. The sliding bearing structure comprises the economizer supporting beam and a girder, wherein the lower end of the economizer supporting beam is fixedly connected with the upper end of a steel plate, and the lower end of the steel plate is fixedly connected with a stainless steel plate; the sliding bearing structure is characterized in that a concave plate with a spherical groove formed in the upper end is fixedly mounted on the girder, a matched convex plate provided with a spherical bulge is arranged in the arc-shaped groove, the upper end of the convex plate is fixedly connected with a polytetrafluoroethylene plate, and the lower end of the stainless steel plate is supported on the upper end surface of the polytetrafluoroethylene plate.
Description
Technical field
The invention belongs to boiler economizer brace summer technical field, be 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 invention provides a kind of sliding support structure for boiler economizer brace summer, 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 invention, 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. 1 is prior art structural representation;
Fig. 2 is structural representation of the present invention;
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.
