Description
Technical field
The utility model relates to excavator technical field, a kind of back-hoe bucket and the dual-purpose two-way use of shell bucket are specifically provided
Power Multi-section expansion arm.
Background technique
Excavator telescopic boom is installed in a kind of equipment on excavator, it is by fixed body and moving body by stretching
The effect of cylinder makes moving body stretch out and retract, to reach bigger excavating radius and reasonable entrucking height.With the epoch
Progress, construction requirement is higher and higher, and subway, river course clear up, sinking well engineering, high-rise building basis etc. are required to be deep-cut or far
It digs, traditional extension arm only has 25 meters of length, and bucket capacity is small.
Conventional excavators telescopic arm structure is a fixed body, and other moving bodys are incorporated into fixed body；Principle is one
Section connects two sections, two sections and connects three sections ... makes it stretch out or retract by stroke oil cylinder again, and excavator is made to have bigger operating radius.
Traditional telescopic arm pulley structure and telescoping cylinder are arranged inside arm, maintenance and its inconvenient, more change steel rope
Or when oil cylinder, need to tear arm open.In addition, its excavation mode of traditional telescopic arm is shell type grab bucket, the principle of telescopic arm is used
Expand the operating radius of excavator.Its shortcoming is that inner cylinder and shell type grab bucket connect, shell type grab bucket is suitable only for excavating pine
It dissipates, soft material；Further, the telescopic arm intensity designed is suitable only for shell type grab bucket, cannot connect traditional backhoe
Bucket；Further, because of the mode that shell type grab bucket is an axis connection, in actual operation, shell type grab bucket remains vertical
Straight direction is excavated, and the material of excavating depth vertically downward is suitable only for；And domestic construction requirement is higher and higher at present, material is not
Only vertical excavation, more construction environments are distally to excavate, and need telescopic arm flattened.
In addition, it is necessary to explanation, the utility model not makes change on the basis of above-mentioned utility model, this is practical
Novel telescopic arm structure is inventor's creation, has difference with above-mentioned utility model.
It is described the difference is that, traditional telescopic arm is unidirectionally to use the arm of force, when telescopic arm falls, by arm from
Decline again, only exert oneself when promoting inner cylinder and material, is only capable of material below vertical excavation.
