Abstract
A long earth auger using a hydraulic main hoist consists of a pile frame, a drilling system and a hydraulic main hoist system, wherein the pile frame comprises a chassis as well as a frame lifting device and an upright column which are connected with the chassis; a main pump motor is arranged on the chassis; the main pump motor drives the hydraulic main hoist in the hydraulic main hoist system to work; the hydraulic main hoist is connected with the drilling system through a steel wire rope and a pulley block; and the drilling system consists of a hydraulic power head, an auger stem and an auger bit which are sequentially connected with one another. When the hydraulic main hoist provided by the utility model is applied to a large-diameter deep-hole long earth auger, because the hydraulic main hoist is stable to control speed and is not influenced by active load, compared with the traditional long earth auger with an electric main hoist in China, the long earth auger using the hydraulic main hoist has the advantages of small vibration, no noise, large output torque and strong adaptability to stratums and the like; and the long earth auger using the hydraulic main hoist solves problems of big motion image, incapability of precisely regulating speed and easy blocking and jamming of the auger bit, resulting from the weak points such as the load characteristics of the motor when the traditional long earth auger with the electric main hoist is used for drilling holes or the auger bit is pulled out.
Description
Technical field
The utility model relates to the piling machinery in the engineering machinery field, specifically a kind of full screw earth auger that can adapt to the employing hydraulic pressure main winch of field large diameter, deep borehole pore-forming needs such as building, bridge, railway better.
Background technology
Domestic full screw earth auger main winch all adopts automatically controlled form at present, carries out step speed regulation through cam controller.Not enough below this structure exists: 1. because the load characteristic of motor, it is big to cause motion to impact, and accurately speed governing can't realize that the high pulling torque slow-speed of revolution steadily holes.2. unit head and drilling system move downward by gravity when holing, when having initiatively load, because hoist engine can't provide a stable lowering velocity for drilling system; Cause transfer when operation speed can be more and more faster; Must manpower compress brake and just can control lowering velocity well, bring inconvenience to the operator, if the brake(-holder) block serious wear; Be easy to cause major accident, borehole stability property deficiency also makes complete machine have very big potential safety hazard.3. the automatically controlled main winch that uses on present domestic full screw earth auger output torque and pulling force under the restriction of space, chassis size is limited, can not adapt to the needs of field large diameter, deep boreholes such as building, bridge, railway.
Summary of the invention
The utility model solves the technical scheme that its technical problem adopted: replace automatically controlled main winch to solve having now problems such as full screw earth auger borehole stability property is poor, output torque is little and pulling force is little with the hydraulic pressure main winch, satisfy large diameter, deep borehole pore-forming needs.
For addressing the above problem, the utility model adopts following technical scheme:
The utility model is made up of pile frame, drilling system and hydraulic pressure master winch system; Described pile frame comprises chassis and rack device and the column that are connected with the chassis, on described chassis, main pump motor is set, and main pump motor drives the hydraulic pressure main winch work in the hydraulic pressure master winch system; Described hydraulic pressure main winch is connected drilling system through wire rope with assembly pulley; Described drilling system is made up of the hydraulic power head, auger stem and the augers that connect successively.
Between described chassis and the column diagonal brace is set.
Described hydraulic pressure master winch system comprises drive motors, and drive motors is connected with hydraulic pump, and described hydraulic pump is gone into main valve with the oil pump in the hydraulic oil container, and main valve is connected with the motor of hydraulic pressure main winch.
Described main valve also is connected with equalizing valve.
A kind of long-spiral drilling machine of hydraulic pressure main winch and long-spiral drilling machine of domestic used automatically controlled main winch of adopting of the utility model compared; Has following beneficial effect: when the utility model hydraulic pressure main winch is used for the large diameter, deep borehole full screw earth auger; Because it is speed controlling and do not receive the initiatively characteristic of load effect stably; Compare with the automatically controlled master winch full screw earth auger of present domestic use have that vibration is little, noiselessness, output torque reach advantages such as the stratum adaptive capacity is strong greatly; Be very suitable for the application of large diameter, deep borehole full screw earth auger, solved traditional automatically controlled master winch full screw earth auger boring and pull out when boring because problems such as big, accurately speed governing, easy vexed drill chuck brill are impacted in the motion that the weakness such as load characteristic of motor cause.At present domestic in addition electric-controlled type full screw earth auger pulling force is at 64 tons to 80 tons; The bore diameter limit is 0.8 meter; Drilling depth is below 32 meters; The pulling force that hydraulic pressure master winch full screw earth auger is 100 tons can satisfy once the stake hole that drill diameter 1.2m is dark 35 meters efficiently, has adapted to the needs of field large diameter, deep boreholes such as building, bridge, railway.
