Description
Technical field
The present invention relates to a kind of engineering machinery, particularly a kind of fluid pressure type engineering driller.
Background technology
Engineering driller is the rig of constructing for the large-diameter bored pile of the engineerings such as power construction, bridge, highrise building, dykes and dams, port and pier.
In prior art, traditional mechanical circulation drilling machine is by motor or internal combustion engine as power source, and drive speed transmission or reducer switch by commutator power or the volume field mechanomotive force that power transmission shaft realizes drill power head respectively again.Wherein the transmission of a kind of circulation drilling machine unit head and hoisting transmission respectively arrange a set of transmission system.The chuck of unit head has the top being arranged on dynamic head main spindle, or be arranged on the below of main shaft, main drilling rod to be loaded in chuck square hole or hexagon ring and to be clamped by main drilling rod.
Mainly there is following deficiency in the engineering driller of said structure: one, the unit head of motor drive speed transmission or reducer, slewing range is little or only have rated speed, therefore dynamic torque change is little, creeps into difficulty, to the poor stability of large-diameter bored pile construction to bad ground.Two, the assembly such as speed changer, reducer, commutator does not all arrange safety overload protective device.Easily component are caused, especially to the damage of first bevel gear when creeping into bad ground.Three, end brake wheel in hoist engine left and right is equipped with and promotes lock and braking brake, between two band-type brakes, self-locking device is not housed, when lifting band-type brake and braking brake stop simultaneously tightly just may cause mechanical accident or component damaged.Four, main drilling rod is clamped by unit head chuck, rely on column or portal frame oil cylinder movement unit head, because hydraulic cylinder directly acts on drilling rod, apparatus arrangement limited space, cause the usual shift motion of drilling rod to be about 0.5-1 rice, so creep into apart from short, directly affecting castinplace pile once loads and unloads construction, add simultaneously and creep into mobile number of times, reduce drilling construction efficiency.Five, flange dock drilling rod bolt connects, and end face is male and female tongue and groove clamping, and male and female tongue and groove processing technology is poor, and fabricating cost is higher.Six, the support crept into does not arrange pylon, in order to the needs of drilling construction, encloses vertical triangle pylon at aperture place, reach construction process requirement by lifting device of jenny by triangle pylon.Rig and pylon divide other to arrange pylon can be caused to install difficulty, mobile difficulty, and pylon stationarity and poor stability.Seven, rig does not arrange running gear, even if what have is provided with running gear, but walking coordinate is all imperfect, often general rig only arranges longitudinal moving device, rig is then moved with drill rod sled in other orientation, both time-consuming, difficult mating holes position again, can cause drilling-machine shifter, the difficulty of mating holes position at this point.Eight, outbalance, existing engineering driller complex structure, bulky, mobile and transhipment very inconvenience, not only cost is higher, and has a strong impact on efficiency of construction.Nine, the impact of space structures causes existing engineering driller drilling rod to lengthen comparatively difficulty, and efficiency is lower, affects programming.
Therefore, need a kind of engineering driller, simple and light, have good mobility, floor space is little, and job area is wide, reduces labour intensity, saves use cost and cost of labor, can be used for engineering pile hole construction, and meet technological requirement; Meanwhile, optimized device arrangement space, increases and creeps into stroke, reduces and creeps into mobile number of times, thus improves drilling construction efficiency.
