Abstract
The utility model discloses a small lifting lug for a gantry hook of a ladle crane. The small lifting lug consists of steel pipes, a steel plate (2) and U-shaped reinforcing ribs, wherein the U-shaped reinforcing ribs (4) are welded on the 320mm steel pipe (1), one end of the steel plate (2) is connected with the U-shaped reinforcing ribs (4) and the 320mm steel pipe (1) in a welding manner, and the other end of the steel plate (2) is welded on the steel pipe (3) which is 80mm long. The small lifting lug has the characteristics that the self-weight is small and that the defects are easy to find.
Description
Technical field
The utility model relates to mechanical field, especially a kind of little hanger of ladle carne gantry hook.
Background technology
The keystone configuration of gantry hook is comprised of assembly pulley, lifting beam with hook, little hanger, stacked suspension hook etc.The little hanger of traditional dragon gate stop is forging structure, sees Fig. 1, and material is 20MnSi.The major defect of this structure is: (1) little hanger is from great, and 100 tons of ladle carne hangers deadweights are 520kg approximately;
(2) little hanger is " U " type structure, and thickness is large, and 100 tons of little hanger thickness of ladle carne are 100mm, and R190 place bending spring is little, the bad assurance of material structure performance;
(3) every chassis needs two little hangers, and quantity is few, the bad batch manufacturing of organizing, the very difficult contact of forging external coordination producer;
(4) little hanger solid forging, stock left for machining is large, and it is little that " U " locates the gap, and 100 tons of ladle carnes are 150mm, and forging producer is many forges it for solid, and processing capacity is large;
(5) forging defect is difficult for finding.
Summary of the invention
In order to solve the existing little hanger of heavy-duty machine gantry hook from great, the ND shortcoming of defective, the utility model proposes a kind of little hanger of ladle carne gantry hook, it has the advantages that deadweight is little, defective has been found.
The technical scheme that its technical matters that solves the utility model adopts is: this little hanger is comprised of steel pipe, steel plate, " U " type reinforced rib, " U " type reinforced rib be welded on the 320mm steel pipe, steel plate one end is in the same place with the 320mm steel-pipe welding with " U " type reinforced rib, and the other end is welded on long 80mm steel pipe.
The material of described steel pipe is the 20# solid drawn pipe, and " U " type reinforced rib is cut into by the Q345B steel plate.
Described steel plate one end has circular hole, and the size in hole equates with the internal diameter of 80mm steel pipe.
By changing the little hanger forging structure of ladle carne gantry hook form into the welded structure form, not only alleviated the deadweight of gantry hook, increase tap, reduce the machinework expense, further verified welded preceence.
Description of drawings
The structural representation of the existing little hanger of Fig. 1;
The generalized section of Fig. 2 Fig. 1;
Fig. 3 structural representation of the present utility model;
The cross-section illustration intention of Fig. 4 Fig. 3;
1.320mm steel pipe in figure, 2. steel plate, 3. 80mm steel pipe, 4. " U " type reinforced rib.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in accompanying drawing 3,4, this little hanger is welded on 320mm steel pipe 1 by two " U " type reinforced ribs 4, steel plate 2 one ends and " U " type reinforced rib 4 and 320mm steel pipe 1 weld together, the other end is welded on long 80mm steel pipe 3.
" U " type reinforced rib 4 and steel plate 2 are the Q345B steel plate cutting, and length direction must be consistent with the steel plate rolling direction.80mm steel pipe 3 adopts the blanking of 20# solid drawn pipe, and the material structure performance is good.All adopt continuous fillet welds, the leg height is 2/3 of the light sheet thickness in connection place.Adopt ER50-6 welding wires or E5016, E5015 welding rod to weld during welding, steel pipe and steel plate 2 place's weld seams adopt multi-pass welding, adopt little standard welding parameter to weld, and control welding deformation.Postwelding carries out annealing in process to eliminate internal stress.
After changing structure of the present utility model into, take 100 tons of gantry hooks as example, little hanger improves approximately 170kg of rear weight saving, and every stove tap increases by 0.34 ton; Next changes the every cover of welded structure into and reduces approximately 7560 yuan of machined piece expenses.Use through nearly 2 years proves, satisfies operating needs fully.
