Smoke air flue fixing bracket

Abstract

The invention discloses a smoke air flue fixing bracket. The cross section of a smoke air flue is of a rectangular structure. The bracket comprises main fixing bracket bodies. Guiding and positioning structures of movable bracket bodies are arranged on the fixing bracket; the main fixing bracket bodies are arranged at the portions, located at two perpendicular and symmetrical center lines, of the outer side of the smoke air flue correspondingly; movable bracket bodies comprise horizontal sections, perpendicular sections and tilting sections; horizontal sections of right-angle tripods are matched with the guiding and positioning structures; the perpendicular sections are connected with reinforcing ribs of a smoke air flue body; the bottoms of the horizontal sections are connected with horizontal connecting plates; first anti-friction pads are arranged at the bottoms of the horizontal connecting plates; supporting plates are arranged on the upper end faces of the main fixing bracket bodies; second anti-friction pads are arranged on the supporting plates; and second anti-friction pads are matched with first anti-friction pads correspondingly. The smoke air flue fixing bracket is light in quality, compact in structure and small in frictional resistance, the problem that the stress excessive concentration at the position of supporting legs is solved, the phenomena that the smoke air flue is liable to be tore and the supporting legs are liable to fall off due to the fact that operating time is long and start and stop of a unit are frequent are avoided, and the safe, stable and reliable operation of the unit is ensured.

Description

technical field [0001] The invention relates to the technical field of protection and reinforcement structures for smoke ducts, in particular to a fixing bracket for smoke ducts. Background technique [0002] In the prior art, the fixed bracket is a commonly used bracket form in the flue ducts of the electric power, steel and other industries, but the fixed brackets currently used are all directly welded between the tube part and the root of the fixed bracket, but for the radial cross section of the flue Expansion, the fixed bracket cannot compensate, and because the outriggers are rigidly connected, the stress at the outrigger position is excessively concentrated, long-term operation, and the repeated start and stop of the unit can easily lead to tearing of the flue gas duct and loss of outriggers, etc. , affecting the safe and stable operation of the unit. It is necessary to find a more reasonable form of fixing support. Contents of the invention [0003] The purpose o...
