Abstract
The utility model belongs to spare parts of mine excavating equipment, which relates to a shovel rod coupling device of a novel power shovel. One side of a coupling spindle is welded with check rings, and the shovel rod coupling device is characterized in that unilateral clamp coupling is utilized, the other side of the coupling spindle is provided with a fixed limiting groove for arranging a clamp which is equipped with connecting bolts. The shovel rod coupling device of a novel power shovel has advantages of simple structure, convenient operation and disassembly, economy of time and, reducing cost by reusing work-pieces, increasing equipment using periodic and the like.
Description
Technical field
The utility model belongs to mine excavating equipment spare part, relates to a kind of novel power shovel shovel rod coupling.
Background technology
At present, domestic in the excavating equipment of metallurgy industry mine, general employing can be decomposed or undecomposable two kinds of modes, and the former connecting mode of BE-295B power shovel is undecomposable mode, needs gas welding to cut destructive decomposition.Exist: problems such as the operating time is long, workpiece is scrapped, cost height, labor strength height.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose provides a kind of simple in structure, for convenience detach, novel power shovel shovel rod coupling of improving the equipment life cycle, reducing cost.
The novel power shovel shovel of the utility model rod coupling content Description:
The novel power shovel of the utility model shovel rod coupling has back-up ring at a face down bonding of coupling spindle, it is characterized in that: adopt one-sided clip to connect, have the fixed limit groove at the opposite side of coupling spindle clip is set, clip is provided with connecting bolt.
The novel power shovel of the utility model shovel rod coupling, have simple in structure, easy to operate, for convenience detach, save time, workpiece reuses and falls cost, improves characteristics such as equipment life cycle.
Description of drawings
Fig. 1 is novel power shovel shovel rod coupling structural representation
Among the figure: the 1st, clip, the 2nd, attachment bolt, the 3rd, coupling spindle.
The specific embodiment
The novel power shovel of the utility model shovel rod coupling is achieved in that to do below in conjunction with accompanying drawing and specifies.See Fig. 1, the novel power shovel of the utility model shovel rod coupling has back-up ring at a face down bonding of coupling spindle 3, adopts one-sided clip to connect, have the fixed limit groove at the opposite side of coupling spindle 3 clip 1 that high-strength cast steel material is made is set, on clip 1, be provided with high strength connecting bolt 2.The thickness of clip 1 reaches 50 * 20mm.And easy to use, quick, saving cost.
This novel power shovel shovel rod coupling, overcome former coupling spindle φ 180 * 700 both sides and used the back-up ring welding, weldering meat girth 550mm, 20 * 20, need long (single-piece/2 hour of field Welding, take-down time, 4 axles of every scraper bowl) and the short cost height of life cycle, can not reuse problems such as operating difficulties.Solved the requirement of changing 1 reparation spader in field requirement every 3-4 month, make easy to operate, save time, workpiece reuses and falls cost, improves the equipment life cycle.
