Abstract
Double-double distributed rigid beam corner structure. The tube wall that power transmission device belongs to bears the ability again limitedly, and to the great and furnace of size be square or nearly square boiler, the load of stiffening beam bight is great, in order to adapt to the bearing capacity of tube wall, needs to reduce stiffening beam interval and reduces stiffening beam bight 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), the upper and lower both sides of angle plate all with two force transfer device welding, two force transfer device include two biography power board (2) and fixed plate (3), two biography power board with the fixed plate welding, the fixed plate pass through a plurality of liners (4) and tube wall welded fastening, two biography power board of two force transfer device between the welding. The double-double distributed rigid beam corner structure is used for the double-double distributed rigid beam corner structure.
Description
The technical field is as follows:
the invention relates to a double-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 detonation 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, be square or nearly square boiler to the great and furnace of size, stiffening beam bight load is great, in order to adapt to the bearing capacity of tube wall, need reduce stiffening beam interval and reduce stiffening beam bight 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 method for safely and effectively transmitting a large corner load to a pipe wall on the premise of meeting the requirement of expansion, and further enlarging the arrangement distance of rigid beams so as to reduce the cost.
The above purpose is realized by the following technical scheme:
a double-double distributed rigid beam corner structure comprises: the upper side and the lower side of the angle plate are welded with the double force transmission devices;
the double force transmission device comprises a double force transmission plate and a fixed plate, the double force transmission plate is welded with the fixed plate, and the fixed plate is welded and fixed with the pipe wall through a plurality of gaskets.
And the double force transmission plates of the two double force transmission devices are welded.
The double-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 double-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 double-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.
The invention distributes the load through the double force-transmitting devices, so that the pipe wall is in the 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.
Description of the drawings:

Example 2:
according to the corner structure of the double-double distributed rigid beam in the embodiment 1, two sides of the corner plate are connected with the connecting plate 7 by the pin shaft assemblies 9.
Example 3:
according to the double-double distributed rigid beam corner structure in the embodiment 1 or 2, the connecting plate is connected with the end plate 8 by using the pin shaft assembly.
Example 4:
according to the double-double distributed rigid beam corner structure in the embodiment 1, 2 or 3, the end plates are welded with the rigid beam end webs.
The invention realizes the safe transmission of large load at the corner of the boiler rigid beam. It features that the two force transfer devices on both sides are welded to angle plates, which are connected by pin axle assemblies, connecting plates and end plates, which are welded to the end web of rigid beam. The double force transfer device is formed by welding a double force transfer plate and a fixed plate, and the fixed plate and the pipe wall are welded by adopting a liner. Through arranging the structure, the corner load of the large rigid beam can be safely and effectively transmitted, and the pipe wall can bear the corner load.
