The number of component is four, and the combination housing is rectangle, and the combination inside casing is rectangle.Combination inside casing and the positioning component
Between weld together, it is described combination housing and positioning component between weld together.
In the utility model, the combination housing includes housing horizon bar and housing vertical rod, and four housing horizon bars enclose
Into a rectangle, connected by housing vertical rod between two-layer housing horizon bar.
In the utility model, the combination inside casing includes inside casing horizon bar, connecting plate and the vertical angle steel of inside casing, four inside casings
Horizon bar surrounds a rectangle, is connected by connecting plate between adjacent inside casing horizon bar, between two-layer inside casing horizon bar in
The vertical Bolted angle connection of frame.
In the utility model, the positioning component is fusiformis, and the number of the positioning component is four, the positioning component
On be provided with two location holes.
In the utility model, upper supporting leg will be installed in lower revolution fulcrum bearing, supporting leg is then passed through into adapter sleeve and alignment pin
Axle is fixed on the location hole of positioning component.
Beneficial effect：The utility model simple structure, can the tower lifting of rapid processing in the case of no large-scale vertical lathe
Fulcrum bearing is turned round under machine, is brought great convenience to production.

Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to Fig. 1, the structural representation of fulcrum bearing positioning group mounted welder is turned round under derrick crane, derrick crane is next time
Turn fulcrum bearing positioning group mounted welder, including combination housing 1, combination inside casing 2 and positioning component 3, the combination inside casing 2 is located at combination
Inside housing 1, positioning component 3 is connected between the combination housing 1 and combination inside casing 2, the number of the positioning component 3 is four
Individual, the combination housing 1 is rectangle, and the combination inside casing 2 is rectangle.It is welded between the combination inside casing 2 and positioning component 3
Together, weld together between the combination housing 1 and positioning component 3,
The structural representation that fulcrum bearing positioning group mounted welder combines housing, described group are turned round referring to Fig. 2, under derrick crane
Closing housing 1 includes housing horizon bar 11 and housing vertical rod 12, and four housing horizon bars 11 surround a rectangle, two-layer housing water
Connected by housing vertical rod 12 between flat bar 11.
The structural representation that fulcrum bearing positioning group mounted welder combines inside casing, described group are turned round referring to Fig. 3, under derrick crane
Closing inside casing 2 includes inside casing horizon bar 21, connecting plate 22 and the vertical angle steel 23 of inside casing, and four inside casing horizon bars 21 surround a square
Shape, is connected between adjacent inside casing horizon bar 21 by connecting plate 22, and the vertical angle steel of inside casing is passed through between two-layer inside casing horizon bar 21
23 connections.
Referring to Fig. 4, the structural representation of fulcrum bearing positioning group mounted welder positioning component is turned round under derrick crane, it is described fixed
Hyte part 3 is fusiformis, and the number of the positioning component 3 is four, and two location holes 31 are provided with the positioning component 3.
Fulcrum bearing positioning group mounted welder use state is turned round referring to Fig. 5, under derrick crane with reference to figure, when using, by under
Upper supporting leg 6 is installed on pivoting support seat 7, supporting leg 6 is then fixed on determining for positioning component 3 by adapter sleeve 5 and alignment pin 4
On the hole 31 of position.
When using, fulcrum bearing 7 is turned round under the positioning crane of positioning component 3 by lower revolution fulcrum bearing positioning group mounted welder
The lower plane of supporting leg 6, lifting crane climbing frame supporting leg 6 and the tower standard knot coupling sleeve of fixation, in lower pivoting support after being positioned
