Abstract
The utility model relates to a high-temperature supporting beam end supporting device capable of bearing large loads. A beam of a traditional supporting preheater of a steel structure bears heat with a low heat value and small in load, a mode that the beam is connected with other beams in a welded mode is adopted, the swelling problem is solved only with the help of deformation of other beams, under the large load condition at the high temperature of 400 DEG C, the traditional fixing and connecting mode causes huge swelling amount which cannot be absorbed by means of deformation, meanwhile, a beam end is lack of powerful restriction, and it is showed that the original welding structure cannot meet the requirement of high-temperature use. The high-temperature supporting beam end supporting device capable of bearing the large loads comprises a beam end web 1, wherein the beam end web is connected with a beam end 2, the bottom surface of the beam end portion is supported against the top surface of a supporting base 4 through a roller set, the upper portion and the lower portion, corresponding to the beam end, of a supporting body 5 are respectively provided with a set of a bracket 6 in a welded mode, and the beam end web is installed in the brackets. The high-temperature supporting beam is applied to a preheater beam.
Description
technical field:
the utility model relates to a kind of high temperature supporting beam end bearing device that bears large load.
background technology:
the traditional steel work supporting preheater joist support calorie value that is heated is lower, and load is less, and all adopts the connected mode of welding with other beams, only relies on the distortion of other beams to solve expansion issues.Under 400 ℃ of high temperature and large load in the situation that, this traditional connected mode that is fixedly connected with, causes its great swell increment to absorb by distortion, and while beam-ends lacks strong constraint, and visible original welded construction cannot meet applied at elevated temperature requirement.
summary of the invention:
the purpose of this utility model is to provide a kind of high temperature supporting beam end bearing device that bears large load.
above-mentioned object realizes by following technical scheme:
a kind of high temperature supporting beam end bearing device that bears large load, its composition comprises: web plate, described web plate tie-beam end, the underrun roller groups of described beam end is supported on the end face of bearing, on supporter, one group of bracket is respectively welded in corresponding beam-ends upper and lower part, and described web plate is arranged in described bracket.
the described high temperature supporting beam end bearing device that bears large load, described bracket is positioned at the left and right sides of described web plate, between described bracket and described web plate, has gap.
the described high temperature supporting beam end bearing device that bears large load, described beam-ends bottom surface arranges roller groups, and described bracket is truncated wedge.
the beneficial effects of the utility model:
1. the utility model arranges the end face that roller bearing reaches bearing below beam end, whole like this preheater beam can not produce the situation of tearing because of the fixedly welding of beam end in the expansion process of being heated, and leave space between the bracket that beam end arranges in the left and right sides, web plate top, be beneficial to expand has restriction ability to beam end simultaneously, makes beam end not produce torsion.
2. the utility model web plate both sides arrange bracket, guarantee under larger beam-ends counter-force, the permanently effective steady operation of this device energy, beam-ends does not produce torsion simultaneously, the free wxpansion that can solve high-temperature heating beam can be born again larger beam-ends counter-force, guarantee the monolithic stability of beam, the application life and the service property (quality) that extend whole preheater beam.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is plan structure schematic diagrames of the present utility model.
the specific embodiment:
embodiment 1:
a kind of high temperature supporting beam end bearing device that bears large load, its composition comprises: web plate 1, described web plate tie-beam end 2,3 groups of end faces that are supported on bearing 4 of underrun roller bearing of described beam end, on supporter 5, one group of bracket 6 is respectively welded in corresponding beam-ends upper and lower part, and described web plate is arranged in described bracket.
embodiment 2:
the high temperature supporting beam end bearing device that bears large load described in embodiment 1, described bracket is positioned at the left and right sides of described web plate, between described bracket and described web plate, has gap 7.
embodiment 3:
the high temperature supporting beam end bearing device that bears large load described in embodiment 1 or 2, described beam-ends bottom surface arranges roller groups, and described bracket is truncated wedge.
Claims (3)
1. the high temperature supporting beam end bearing device that can bear large load, its composition comprises: web plate, it is characterized in that: described web plate tie-beam end, the underrun roller groups of described beam end is supported on the end face of bearing, on supporter, one group of bracket is respectively welded in corresponding beam-ends upper and lower part, and described web plate is arranged in described bracket.
