Description
Technical field
The invention belongs to mining machinery technical fields, and in particular to a kind of more cabinet reverse shovel grab dippers.
Background technique
Dipper is the structural member that one of structure of excavator most critical and excavator are easiest to Cracking Failure.Tradition is dug
Pick machine bucket rod structure is the big cabinet of monolith, and structure is simple, and antitorque and bending resistance is lower, is only used for the operation of the underloading earthwork.
In order to enhance the structural strength of excavator boom, common method is exactly to weld stiffening plate at the position for being easy to snap, with increase
The method of key position thickness increases structural strength, to extend the service life of dipper.It is disliked when in face of rock or heavy duty etc.
Under bad operating condition, traditional dipper then can easily crack, even if the thickness for increasing key position is still unable to satisfy need of work,
Dipper needs after failure re-replace, and not only bothersome time-intensive, expensive but also can reduce working efficiency.
Summary of the invention

Such as these improvement: groove weld is optimized for the composite weld of groove weld and fillet weld, by simple groove
Weld seam is improved to the groove weld with backing plate, and external fabrication hole is improved to fabricated construction etc..
Such as these wettings: increase reinforcement structure, mechanical limit structure, hoisting structure on the basis of structure of the invention
Deng.
To sum up, the present invention provides a kind of more cabinet reverse shovel grab dippers, traditional dipper is solved compared with big load
And the case where snapping failure is easy under the action of impact force.Entire dipper is separated into three big cabinets by side plate by the present invention,
Each big box house is separated into several small box by stiffening plate, and the orderly cross-distribution of these small box forms backhoe
More body structures of formula excavator boom.The distribution of the internal reinforcing plates of middle cabinet is complex because in middle cabinet with outside
The middle rear support component of oil cylinder connection and the middle lower support component that connect with swing arm are all located at middle cabinet rear portion, and stress compared with
Greatly, the power that middle rear support component and middle lower support component are subject to is dispersed to left case here by multiple stiffening plates of cross-distribution
In body and right case.Wherein, middle stiffening plate III 308, middle stiffening plate IV 309, I 310B of stiffening plate, II 310C of stiffening plate are played pair
The stress of middle rear support component is transmitted and 304 supporting role of rear blanking plate component in round tube 310A.Middle stiffening plate I 306, in
Stiffening plate II 307 is radioactive to be distributed in around middle lower support component, is conducive to for the stress of middle lower support component being transferred to respectively
In a cabinet.It can quickly and effectively disperse the load and impact force that dipper is subject to be transferred to each small case by this method
In body, the maximum stress that the present invention is subject to is reduced, the harm of stress concentration is dropped, so that structural strength of the invention is increased,
Extend service life.
The present invention also provides a kind of excavators, including more cabinet reverse shovel grab dippers above-mentioned.
