Description

Multifunctional excavator
Affiliated technical field
The utility model belongs to the constructional engineering machinery technical field, and what relate generally to is a kind of multifunctional excavator.
Background technology
Constructions such as the excavation earthwork that relates in building engineering construction at present,, pile foundation pore-forming, stake hole rotary enlarging reducing moulding generally need by excavator, rig and revolve enlarging aiguille operation respectively.Excavator mainly contains crawler type and wheeled two kinds, and function is removed for excavating cubic metre of earth and adding vibration hammer.Rig is mainly used to finish the pore-forming of pile foundation in engineering, as long-spiral drilling machine, rotary drilling rig etc.The power of these rigs is mostly more than 100KW, and highly also more than 20 meters, more than 20 ton of weight because drilling rod and drill bit all rotate during power drive, causes brill to be subjected to the restriction of driving power size and torsional forces size deeply.It is matching used with long-spiral drilling machine revolving enlarging aiguille, this revolves enlarging aiguille, and (patent No.: invention ZL02212479.9) has changed that traditional friction pile bearing capacity of single pile is low, waste concrete, slow, the unsafe defective of constructing of waste steel, speed of application, problems such as squeezed reducing effect is low, moulding is lack of standardization, can't construct in the large and small stake of fullness coefficient footpath have also been changed, make pile foundation part and traditional pile foundation compare, save concrete 30-70%, save the duration 40%, save fund 25-50%.But owing to it can only be used with long-spiral drilling machine, and the long-spiral drilling machine power consumption is big, the tall and big heaviness of fuselage, and displacement is difficulty.
Summary of the invention
The purpose of this utility model promptly produces thus, a kind of multifunctional excavator is proposed, make excavator in building operations, both can excavate cubic metre of earth, remove, again can pile foundation boring and to stake hole rotary enlarging reducing, can also lift reinforcing cage, the weight of slinging carries out tamping operation at the bottom of to hole, stake hole.
For achieving the above object, the technical scheme that the utility model is taked is: master winch is set on the excavator body and pays elevator, wherein master winch is fixedly connected by the hypomere sleeve pipe of wire rope and drilling rod, drilling rod is an extendable sleeve structure, it is installed in excavator and disassembles on the longbow arm and big bow arm oil feeding cylinder behind the Excavating bucket, lower end at drilling rod is connected with unit head, this unit head comprises housing, motor and speed reducer, housing is connected with drilling rod, motor and speed reducer is arranged in the housing, and its power output shaft is connected with drill bit; The wire rope of secondary elevator is used to lift reinforcing cage or weight.
The utility model design is unique, rational in infrastructure.Because that it is provided with is main, pay elevator, and can realize different operation functions by on the longbow arm of excavator and longbow arm oil cylinder, assembling different power tools (Excavating bucket, drilling rod) on excavator.Like this, not influencing the existing excavation earthwork of excavator and adding under the prerequisite of vibration hammer dismounting, increased the function of pile foundation boring and stake hole rotary enlarging reducing again.And pay elevator and also have the function that lifting reinforcing cage, the weight of slinging carry out tamping operation at the bottom of to hole, stake hole.Because drilling rod is a telescopic sleeve structure, and drives the bottom that power is positioned at drilling rod, during operation, drilling rod does not rotate, reduced the loss of power and torsional forces thus, made to bore not to be subjected to restriction (restriction of watt level, torsional forces size) deeply, can add tubing (drilling rod) increase arbitrarily and bore dark.By changing the actuating unit of different capacity, can also strengthen bore diameter arbitrarily.Effectively reduce construction cost, improved operating efficiency, reduced the overlapping investment of equipment.The utility model also has use (displacement), transition is flexible, the characteristics that power consumption is little.
