Abstract
The invention discloses a sliding-structured platform staircase suitable for a thermal expansion working condition, relates to the platform staircase suitable for the thermal expansion working condition, and solves the problem of risk in tension fracture and permanent deformation due to the fact that stress of welding seam of an external pre-welding part, welding seam between supporting channel steel and a platform frame and welding seam between the platform frames is overlarge by utilization of a conventional platform installation manner under the condition of large thermal displacement. The platform staircase is characterized in that an upper supporting steel structure is a channel steel frame structure; the channel steel frame structure is provided with a waist-shaped hole groove; the longitudinal direction of the waist-shaped hole groove is consistent with that of the channel steel frame structure; a lower slide steel structure is an angle steel slide structure; the angle steel slide structure is welded on a lower steel supporting structure; the angle steel slide structure is connected with the channel steel frame structure through bolts; the bolts penetrate through the waist-shaped hole; a lubricating material plate is arranged between the angle steel slide structure and the channel steel frame structure. The sliding-structured platform staircase disclosed by the invention is suitable for connecting an upper overhaul platform of large-scale equipment with an equipment main body under the thermal expansion working condition.
Description
Technical field
The present invention relates to a kind of platform stair adapting to thermal expansion operating mode is and in particular to a kind of cunning of adaptation thermal expansion operating mode
Dynamic structure platform stair.
Background technology
Because power plant and chemical plant some horizontal equipments axial dimension is longer, operationally, equipment thermal walking is larger.If
Routinely stage+module form, directly will support channel-section steel to weld with Deaerator Table, in the case of so big thermal walking, easily
Lead to device external clip weld seam, support the stress mistake that between channel-section steel and platform framework, between weld seam and platform framework, weld seam bears
Greatly, there is the risk of drawing crack, permanent deformation.It would therefore be highly desirable to design a kind of new platform attachment structure, to solve that length is longer to be set
The safety and stability problem of standby setting inspection platform.
Content of the invention
Brief overview with regard to the present invention is given below, to provide basic with regard to certain aspects of the invention
Understand.It should be appreciated that this general introduction is not the exhaustive general introduction with regard to the present invention.It is not intended to determine the pass of the present invention
Key or pith, nor is it intended to limit the scope of the present invention.Its purpose only provides some concepts in simplified form,
In this, as the preamble in greater detail discussed after a while.
In consideration of it, according to an aspect of the present invention, it is contemplated that a kind of slip knot adapting to thermal expansion operating mode is proposed
Structure platform stair, to solve using normal platform installation form, directly will support channel-section steel to weld with Deaerator Table, in big heat
Under misalignment, it is easily caused device external clip weld seam, supports between channel-section steel and platform framework between weld seam and platform framework
The stress that weld seam bears is excessive, there is the risk of drawing crack, permanent deformation.
The scheme that the present invention is taken is: a kind of slide construction platform stair adapting to thermal expansion operating mode, props up including top
Support steel construction, bottom slideway steel construction, bottom steel support structure and lubriation material plate；
Turbogrid plates are laid above upper support steel construction；
Described upper support steel construction is chan frame structure, and chan frame structure has waist-shaped hole groove, waist-shaped hole groove
Longitudinal direction be consistent with the longitudinal direction of chan frame structure；
Described bottom slideway steel construction is angle steel slideway structure, and angle steel slideway structure is welded on the steel support structure of bottom,
Angle steel slideway structure is connected with chan frame structure by bolt, and bolt passes through waist-shaped hole groove, and angle steel slideway structure and channel-section steel
Lubriation material plate is set between frame structure；The lower end of described bottom steel support structure is arranged on horizontal equipment.
Further: described angle steel slideway structure is segmented angle steel slideway structure.
Further: described lubriation material plate is polyfluortetraethylene plate.
Further: described bottom slideway steel construction is i-beam structure.
The effect that the present invention is reached is:
The present invention will be welded and fixed form between inspection platform and equipment, is changed to sliding support form.It is applied to work
When the larger equipment of heat expansion amount inspection platform.The safety and stability solving length longer equipment setting inspection platform is asked
Topic, its advantage is as follows:
1st, it is provided with the chan frame form of kidney-shaped hole slot using top.Channel-section steel form frame stability, can make maintenance put down
Platform carries bigger load, and setting kidney-shaped hole slot is used for coordinating with bottom slideway and is used for fixing top and the bottom structure.
2nd, in the form of lower support upper weld angle steel slideway, and slideway segmentation, multistage can be set, with facility
In the impact reducing heat expansion power.
3rd, using the middle method using lubriation material filling, reduce the friction between rigid face, by water between the two
Flat expansive force is converted into less frictional force.
4th, using fixing upper and lower two rigid structures of bolt and nut so that remaining original welding structure to upper frame
Support and spacing constraint, and solve welding structure impact and limiting frame and support member between lateral swelling pressure excessive
Problem.
In putting equipment in service, upper brace is in normal temperature state, does not produce expansion, during lower part equipment work, temperature raises,
Produce thermal expansion, bottom steel support structure is axially elongated together with the slideway steel construction of bottom, now upper support steel construction is not
Motion, the kidney-shaped hole slot being bolted, to offset the horizontal thermal expansion amount being produced due to heat expansion different it is ensured that equipment and
Safety and stability under action of thermal difference for the inspection platform.Make some main equipments (as longer appearance in the length of horizontal arrangement
Device type equipment) attachment structure between the inspection platform on top and apparatus body is changed.No longer make the cloth of inspection platform
Putting and arranging is affected because the temperature difference produces thermal expansion factor by when device length, work, the connection between Optimization Platform and equipment
Form, improves the thermal (temperature difference) stress situation of the presence between inspection platform and equipment.
