Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of steam drum installation, and specifically relates to a steam drum rolling support. Background Technology
[0002] The steam drum is a core component of a boiler system. Its main function is to participate in the three processes of heating, vaporization, and superheating in the boiler, acting as a connecting hub. Because the steam drum needs to go through these three processes, its temperature fluctuates significantly. Furthermore, due to its large structure, the steam drum undergoes thermal expansion during these processes, causing changes in its volume.
[0003] Generally, although the steam drum's installation structure includes built-in sliding supports, these supports cannot meet the boiler's thermal expansion requirements. The built-in sliding supports suffer from high sliding resistance and high noise levels during operation. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a steam drum rolling support to solve the technical problems of high sliding resistance and high noise in the existing steam drum sliding support.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A steam drum rolling support, comprising:
[0006] The support assembly includes a pair of parallel I-beams;
[0007] A base, located below the support assembly;
[0008] A rolling assembly, wherein the rolling assembly is located between the I-beam and the base;
[0009] Two limiting protective covers are respectively disposed at both ends of the base and correspondingly cover both ends of the support assembly.
[0010] This invention utilizes the rolling mechanism of the rolling component to replace the original sliding mechanism, thereby reducing the resistance and noise of the steam drum during thermal expansion.
[0011] Furthermore, the support assembly also includes a crossbeam, the two ends of which are respectively connected to the sides of the two I-beams.
[0012] The beneficial effect of this step is that connecting the two I-beams with a crossbeam ensures that the two I-beams remain synchronized when moving.
[0013] Furthermore: the rolling assembly includes at least two rollers, and the at least two rollers are connected by a connecting plate;
[0014] The length of the support component is m, and the length of the connecting plate is n, where n > 1 / 2m.
[0015] The benefits of this step are that by forming a plane with at least two rollers and the length of the connecting plate being greater than half the length of the support component, the support component can be prevented from tipping over when the rolling component shifts to one side.
[0016] Furthermore, the base is provided with a pair of limiting plates corresponding to the position of the rolling component, and the distance between the pair of limiting plates is adapted to the width of the rolling component.
[0017] The beneficial effect of this step is that the movement trajectory of the rolling component is maintained by the limiting plate, preventing the rolling component from deviating during back-and-forth movement.
[0018] Furthermore, the distance between the two limiting protective covers is 30-50 mm longer than the length of the support assembly.
[0019] The beneficial effect of this step is that the above-mentioned movement distance is adapted to the thermal expansion deformation of the steam drum.
[0020] The beneficial effects of this utility model are:
[0021] 1. This application utilizes a support component to connect and fix a saddle for the steam drum, thereby supporting the steam drum. Then, a rolling component is used to allow the support component to roll on the base. By using rolling instead of sliding, not only is the resistance during steam drum displacement reduced, but the noise during displacement is also reduced. In addition, in the original sliding structure, the saddle also needs to bear the frictional force of sliding, which can easily affect the connection between the saddle and the steam drum.
[0022] 2. Limit the support components by using a limiting protective cover to match the rolling distance of the support components with the deformation of the steam drum due to thermal expansion. Attached Figure Description
