Fig. 1 is platform floor free bearing welding location schematic representation;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is that the A of Fig. 1 is to view;
Fig. 4 is the built-up shaft schematic representation of Fig. 1.
Embodiment
Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the present invention can make up each other.Below with reference to accompanying drawing and combine embodiment to specify the present invention.
To shown in Figure 4, left free bearing 20 on the platform floor 3 and right free bearing 21 in order to make left free bearing 20 coaxial with right free bearing 21 endoporus, need be installed on left free bearing 20 and the right free bearing 21 through built-up shaft 1 in welding in advance like Fig. 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, and two ends make left setting sleeve 11 coaxial with right setting sleeve 12 installation positions through turning.Second cylindrical 110,120 and first cylindrical the 111, the 121st of left side setting sleeve 11 and right setting sleeve 12 are processed by two circular steel plates that vary in size, and two circular steel plates are formed by connecting through the intermediate rectangular steel.Built-up shaft 1 also can adopt other making method.Second cylindrical 110,120 and first cylindrical 111,121 are coaxial, and first cylindrical, 111 diameters are greater than the diameter of second cylindrical 110, first cylindrical 111 and 121 equal diameters, second cylindrical 110 and 120 equal diameters.When making built-up shaft, first cylindrical, 121 diameters equal first endoporus, 211 diameters of right free bearing 21 simultaneously, and second cylindrical, 120 diameters equal second endoporus, 210 diameters of right free bearing 21.Left side free bearing 20 is identical with right free bearing.
Left free bearing 20 on the platform floor 3 and right free bearing 21 are at first put left free bearing 20 and right free bearing 21 to platform floor 3 welding positions in welding; Jack shaft 10 with ready built-up shaft 1 inserts in left free bearing 20 and the right free bearing 21 then; Next, with left setting sleeve 11 and right setting sleeve 12 pack into from the left side and the right respectively left free bearing 20 and right free bearing 21, first endoporus 211 of right free bearing 21 and second endoporus 210 are cooperated with first cylindrical 121 and second cylindrical 120 of right setting sleeve 12.Similarly, left free bearing 20 matches with left setting sleeve 11.Its endoporus are coaxial after making left free bearing 20 and right free bearing 21 be weldingly fixed on platform floor 3 like this.Next, begin welding, left free bearing 20 is welded on the platform floor 3 with right free bearing 21.Next, pull down left setting sleeve 11 and right setting sleeve 12 and jack shaft 10 from the left side and the right.Welding process is accomplished.
Can find out that from 3 figure first endoporus, 211 diameters of right free bearing 21 are greater than second endoporus, 210 diameters, and be positioned at the outside that same left free bearing 20 is identical with right free bearing 21.Make that like this apertura lateralis is big, inboard aperture is little, is to make right free bearing 21 coaxial with left free bearing 20 four endoporus in welding process through an integral shaft.Simultaneously left free bearing 21 is very big with right free bearing 20 structures, and platform floor also is a macrostructure spare, and operation is very inconvenient, adopts method of the present invention to solve this problem.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
