Step 5: welding operation is carried out to platform floor and left free bearing and right free bearing.
The invention provides a kind of built-up shaft and platform floor free bearing welding method beneficial effect is:
One: adopt built-up shaft frock to realize platform floor free bearing welding concentricity problem, structure is simple.
Its two: adopt built-up shaft frock, left free bearing and right free bearing coaxality high.
Its three: built-up shaft frock, left setting sleeve and right setting sleeve load and take out, easy to operate.
Accompanying drawing explanation
The accompanying drawing forming a part of the present invention is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is platform floor free bearing welding location schematic diagram;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the A direction view of Fig. 1;
Fig. 4 is the built-up shaft schematic diagram of Fig. 1.
Embodiment
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figures 1 to 4, the left free bearing 20 on platform floor 3 and right free bearing 21, when welding, in order to make left free bearing 20 and right free bearing 21 female coaxial, need to be pre-installed on left free bearing 20 and right free bearing 21 by built-up shaft 1.
Built-up shaft 1 comprises jack shaft 10, left setting sleeve 11, right setting sleeve 12, and left setting sleeve 11 is installed on the left end of jack shaft 10, and right setting sleeve 12 is installed on the right-hand member of jack shaft 10.Jack shaft 10 is hollow steel pipe, two ends by turning make left setting sleeve 11 and right setting sleeve 12 installation position coaxial.Second cylindrical 110,120 and first cylindrical 111,121 of left setting sleeve 11 and right setting sleeve 12 is processed by two the circular steel plates varied in size, and two circular steel plates are formed by connecting by intermediate rectangular steel.Built-up shaft 1 also can adopt other making method.Second cylindrical 110,120 and first cylindrical 111,121 is coaxial, and the first cylindrical 111 diameter is greater than the diameter of the second cylindrical 110, the first cylindrical 111 and 121 equal diameters, the second cylindrical 110 and 120 equal diameters.Simultaneously when manufacturing built-up shaft, the first cylindrical 121 diameter equals the first endoporus 211 diameter of right free bearing 21, and the second cylindrical 120 diameter equals the second endoporus 210 diameter of right free bearing 21.Left free bearing 20 is identical with right free bearing.
Left free bearing 20 and right free bearing 21, when welding, are first put to platform floor 3 welding position by the left free bearing 20 on platform floor 3 and right free bearing 21; Then the jack shaft 10 of ready built-up shaft 1 is inserted in left free bearing 20 and right free bearing 21; Next, left setting sleeve 11 and right setting sleeve 12 are loaded left free bearing 20 and right free bearing 21 from the left side and the right respectively, the first cylindrical 121 of the first endoporus 211 of right free bearing 21 and the second endoporus 210 and right setting sleeve 12 and the second cylindrical 120 are coordinated.Similarly, left free bearing 20 matches with left setting sleeve 11.Left free bearing 20 and right free bearing 21 is made to be weldingly fixed on platform floor 3 its female coaxial rear like this.Next, start welding, left free bearing 20 and right free bearing 21 are welded on platform floor 3.Next, left setting sleeve 11 and right setting sleeve 12 and jack shaft 10 is pulled down from the left side and the right.Welding process completes.
As can be seen from 3 figure, the first endoporus 211 diameter of right free bearing 21 is greater than the second endoporus 210 diameter, and is positioned at outside, and same left free bearing 20 is identical with right free bearing 21.Make apertura lateralis large like this, inboard aperture is little, is to make right free bearing 21 and left free bearing 20 four female coaxial in welding process by an integral shaft.Left free bearing 21 and right free bearing 20 structure are very large simultaneously, and platform floor is also macrostructure part, operates very inconvenient, adopts method of the present invention to solve this problem.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
