The tube wall that power transmission device belongs to bears the ability again limitedly, and to the furnace type that corner structure both sides tube wall one side broad one side is narrower, both sides load difference is very big, in order to adapt to the bearing capacity of tube wall, need reduce the stiffening beam interval and reduce stiffening beam tip load, and this will increase the whole number of piles of stiffening beam, makes the cost increase. The invention comprises the following components: the angle plate (1), one side and the welding of single power transmission device of angle plate, the opposite side and the welding of two power transmission device of angle plate, single power transmission device includes single biography power board (7) and second fixed plate (4), single biography power board and second fixed plate welding, the second fixed plate is through a plurality of liners (5) and tube wall welded fastening, two power transmission device include two biography power boards (2) and first fixed plate (3), two biography power boards and first fixed plate welding, first fixed plate is through a plurality of liners and tube wall welded fastening. The invention is used for the corner structure of the single-double distributed rigid beam.
Description
The technical field is as follows:
the invention relates to a single-double distributed rigid beam corner structure.
Background art:
the boiler stiffening beam arranges in the tube wall outside, so that improve tube wall rigidity, prevent boiler furnace deflagration and damage the boiler, the bight structure can transmit stiffening beam tip load to adjacent tube wall on, the scute both sides are single power transmission unit in the current structure, and the tube wall that power transmission unit belongs to bears the ability again limitedly, to the narrower stove type in one side of bight structure both sides tube wall one side broad, both sides load difference is very big, in order to adapt to the bearing capacity of tube wall, need reduce the stiffening beam interval and reduce stiffening beam tip load, this will increase the whole number of piles of stiffening beam, make the cost increase.
The invention content is as follows:
the invention aims to provide a corner structure form of a rigid beam, which can safely and effectively transmit loads with large difference at two sides of the corner structure to a pipe wall and can meet the requirement of expansion.
The above purpose is realized by the following technical scheme:
a single-double distributed rigid beam corner structure, comprising: the angle plate is welded with the single force transmission device on one side and the double force transmission device on the other side;
the single force transmission device comprises a single force transmission plate and a second fixing plate, the single force transmission plate is welded with the second fixing plate, and the second fixing plate is welded and fixed with the pipe wall through a plurality of gaskets;
the double-force-transmission device comprises a double-force-transmission plate and a first fixing plate, the double-force-transmission plate is welded with the first fixing plate, and the first fixing plate is welded and fixed with the pipe wall through a plurality of gaskets.
The single-double distributed rigid beam corner structure is characterized in that the single force transmission plate is welded with the double force transmission plates.
The single-double distributed rigid beam corner structure is characterized in that two sides of the corner plate are connected with the connecting plate through pin shaft assemblies. The single-double distributed rigid beam corner structure is characterized in that the connecting plate is connected with the end plate through a pin shaft assembly.
In the single-double distributed rigid beam corner structure, the end plate is welded with the end web plate of the rigid beam.
Has the advantages that:
1. the expansion offset is reserved at the opening positions of the angle plate and the end plate, so that the boiler can be conveniently heated to expand. The end plates are welded to the spar end webs to enable spar end loads to be transferred through the corner structures to the adjacent side tube walls.
According to the invention, the force transmission devices on two sides are reasonably selected according to different loads on two sides of the corner structure, so that the pipe wall is within a bearing range. Therefore, the space between the rigid beams can be enlarged as much as possible within the allowable span range of the rigid beams, the arrangement layer number of the rigid beams is reduced, steel is saved, and the cost is reduced.
