Description

Technical Field

[0001] The utility model belongs to the field of steel structure construction, and in particular relates to a steel frame supporting structure for supporting a stirrer at the top of a primary tar separator. Background Art

[0002] The primary tar separator is an important equipment for separating gas and water. The stable operation of its top agitator plays a vital role in the entire production process. The agitator is supported on the top of the primary tar separator and driven by connecting parts. Due to unfavorable operating conditions and wear of connecting parts during operation, the agitator position sinks, so that it cannot operate normally and needs frequent maintenance. Frequent maintenance increases the cost of use, and the long maintenance time makes production unable to proceed continuously. Therefore, it is necessary to add a steel structure platform on the top of the primary tar separator to support the agitator.

[0003] A steel platform is added on the top of the primary tar separator. The conventional solution is: new steel structure beams and columns are built from the ground around the primary tar separator, and column supports are set between the steel columns to form a steel frame-support system. A steel platform is set on the top of the steel frame-support system, and the agitator is set on the steel platform. The newly built steel frame-support system has no connection with the primary tar separator. Due to the existence of the primary tar separator, a steel floor cannot be set in the middle. Due to the absence of a steel floor, the first three vibration modes of the steel frame-support system are all in a torsion state under the action of earthquakes or wind; the first and second vibration modes of the general structure are translational, and the third vibration mode is torsion. If the torsion state first appears in the first and second vibration modes, this will cause the steel frame-support system to be destroyed prematurely under the action of wind and earthquake, and at the same time cause large structural deformation, posing a safety risk and affecting the normal operation of the equipment. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a steel frame supporting structure for supporting an agitator, so as to solve the torsional damage of the structure and delay the occurrence of the torsional vibration mode.

[0005] The utility model provides a steel frame supporting structure, which includes supporting steel columns arranged around a primary tar separator, cross beams connecting adjacent supporting steel columns, the cross beams including a top cross beam arranged on the top of the supporting steel columns and a plurality of groups of middle cross beams arranged below the top cross beams, steel components are arranged on the outer sides of the top cross beams and the middle cross beams, and a steel platform for hanging agitators is arranged between the top cross beams.

[0006] Furthermore, the steel assembly includes a horizontal member connected to the supporting steel column, a longitudinal member connected between the horizontal members, and a plurality of supporting rods arranged between the crossbeam and the longitudinal members. Adjacent supporting rods are connected with diagonal braces, and the plurality of diagonal braces are distributed in a wave-breaking shape between the horizontal members. The horizontal member may be, for example, HN250X125 steel, the longitudinal member may be, for example, HN250X125 steel, the diagonal braces may be, for example, equilateral angle steels with a side length of 70 mm and a thickness of 6 mm, and the supporting rods may be, for example, channel steels.

[0007] Furthermore, a supporting steel column is connected to two horizontal members at the same time, with the side where the supporting steel column is connected to the crossbeam as the inner side surface, one of the horizontal members is connected to an outer side surface of the supporting steel column, and the other horizontal member is connected to the other outer side surface of the supporting steel column, and the two horizontal members connected to the same supporting steel column are perpendicular to each other.

[0008] Further, the longitudinal member is connected between two mutually parallel horizontal members, the longitudinal member is parallel to the cross beam, and the distance between the longitudinal member and the cross beam may be, for example, 1-1.5 m, preferably about 1.2 m.

[0009] Furthermore, the support rods are vertically connected to the cross beams and the longitudinal members, and the distance between adjacent support rods is determined according to the intersection positions of the diagonal braces with the cross beams and the longitudinal members. Preferably, the acute angle between the diagonal braces and the cross beams and the longitudinal members is not greater than 55 degrees and not less than 35 degrees.

[0010] Furthermore, a first reinforcing brace is connected between adjacent steel components. The first reinforcing brace enables the steel components on the same layer to form a hoop effect, thereby improving the stability of the entire steel frame support structure.

[0011] Furthermore, there are multiple supporting steel columns that are vertically arranged, and multiple supporting steel columns are arranged around the primary tar separator. The multiple supporting steel columns are distributed in a polygonal shape. For example, there may be four supporting steel columns that are arranged in four directions of front, back, left and right of the primary tar separator. The four supporting steel columns are distributed in a rectangular shape. For example, the supporting steel columns may be steel sections.

[0012] Furthermore, the cross beam is perpendicular to the supporting steel column, and a plurality of cross beams are arranged in sequence along the height direction of the supporting steel column. The distance between adjacent cross beams is determined according to the angle between the support member and the cross beam, and the angle is generally between 35 and 55 degrees.

[0013] Furthermore, the middle cross beams of the same height constitute an middle frame layer with a closed-loop cross section, and the middle frame layers are connected with support members, which are arranged in an "eight" shape between the middle frame layers, with the top of the support member connected to the middle position of the middle cross beam, and the bottom of the support member connected to the meeting point of the middle cross beam and the supporting steel column.

[0014] Furthermore, the corners of the middle crossbeam are connected with first diagonal rods, and the first diagonal rods and the middle crossbeam preferably form an isosceles triangle. The first diagonal rods do not cross each other, and the number of first diagonal rods in each middle frame layer is consistent with the number of supporting steel columns. For example, each middle frame layer is provided with four first diagonal rods, and the first diagonal rods can be, for example, HW150X150 steel.

[0015] Furthermore, the corners of the top crossbeams are connected with second diagonal bars, and the second diagonal bars and the top crossbeams preferably form an isosceles triangle, and the second diagonal bars do not cross each other. The second diagonal bars may be, for example, HW150X150 steel.

[0016] Furthermore, a second reinforcing brace is connected to the intersection of the middle portion of the second oblique rod and the top crossbeam.

[0017] The force-bearing principle of a steel frame support structure provided by the utility model is:

[0018] Under the action of horizontal wind or earthquake, the force is first transmitted to the steel components, then to the beams, then to the supporting steel columns, and finally to the foundation.

[0019] Beneficial effects of the utility model:

The steel frame support structure of the utility model ensures the safety of the structure without setting a floor slab. BRIEF DESCRIPTION OF THE DRAWINGS
