Description
Technical field
The utility model relates to the piling machinery field, relates in particular to a kind of long helical deep hole rig.
Background technology
Long helical deep hole rig is the common equipment that a kind of Foundation Design is built, and is mainly used in the ground drilling construction.Its main structure is as shown in Figure 1: comprise drilling rod 8, workbench 13 and be arranged at the column 9 on the workbench 13, its bearing of trend guiding slidable fit of column 9 upper edges has the unit head 10 that is in transmission connection with drilling rod 8 upper ends, and the periphery of drilling rod 8 is provided with helical blade.Part 11 is for being arranged at the diagonal brace of 9 on workbench 13 and column among the figure, and part 12 is a driver's cabin.Its main operating principle is that liftable unit head drives the drilling rod rotation, and drilling rod is realized creeping under the deadweight effect of itself and unit head.The pore-forming aperture of drilling rod and the size of drilling depth depend primarily on the size of the power of creeping into of output torque and the drilling rod of unit head, and unit head is the critical component of long helical deep hole rig.The unit head of existing long helical deep hole rig adopts alternating current generator and reductor to drive the drilling rod rotation; Output torque improves difficulty; The raising of moment of torsion can only be by increasing the power of speed reducing ratio or increase motor; This just makes unit head must become very huge and heavy, to the stability generation ill effect of long helical deep hole rig.If through adopting the deadweight that increases unit head and drilling rod to increase the power of creeping into, will have relatively high expectations certainly, increase manufacture difficulty and cost of production to the structural strength of rig.
Summary of the invention
The purpose of the utility model is to provide a kind of long helical deep hole rig that can increase the creep into power of drilling rod in drilling process at any time.
In order to address the above problem, the technical scheme of the utility model is:
Long helical deep hole rig; Comprise that periphery has the drilling rod of helical blade, workbench and is arranged at the column on the workbench; First unit head that column upper edge its bearing of trend guiding slidable fit has the upper end with said drilling rod to be in transmission connection; The bearing of trend guiding slidable fit of the column upper edge column of said first unit head below has second unit head; Be rotatably equipped with interior swivel nut in second unit head with internal thread by drive power source; The helical blade of swivel nut and said drilling rod corresponding site cooperates formation screw, lead-screw drive mechanism through the screw thread transmission in described, is provided with in said swivel nut between the described column and second unit head and said second unit head is moved spacing position-limit mechanism along the column bearing of trend at the said drilling rod of driving under the drive of power source when drilling direction creeps into.
The lower end fixed installation of said second unit head is useful on the aperture of when boring, going deep into corresponding stake hole and sentences the casing that stops the stake hole to cave in.
Described first unit head is provided with first hydraulic motor, and the clutch end of the power intake of said first unit head and first hydraulic motor is in transmission connection.
Described second unit head is provided with second hydraulic motor, and described second hydraulic motor is and drives the power source that said interior swivel nut rotates.
The beneficial effect of the utility model: in the drilling process of drilling rod; The first unit head position drilling rod provides driving torque; This moment, drilling rod was equivalent to the leading screw in leading screw, the screw mechanism, and the interior swivel nut of second unit head is equivalent to the screw in leading screw, the screw mechanism, and the interior swivel nut of second unit head provides the power of drilling direction to drilling rod; Thereby increase the power of creeping into of drilling rod; Make drilling rod continue to creep into downwards, first unit head can not dally because the power of creeping into is little, thereby has improved the operating efficiency of whole long-spiral drilling machine.
Description of drawings
Fig. 1 is the long helical deep hole rig of a utility model prior art constructions sketch map;
Fig. 2 is the structural representation of the utility model embodiment.
The specific embodiment
The embodiment of long helical deep hole rig is as shown in Figure 2: comprise drilling rod 4, workbench 8 and be arranged at column 1, diagonal brace 7 and the hoist engine on the workbench 8.First unit head 2 that column 1 upper edge its bearing of trend guiding slidable fit has the upper end with drilling rod 4 to be in transmission connection; The upper end and the hoist engine of first unit head 2 are in transmission connection; The bearing of trend guiding slidable fit of the column 1 upper edge column 1 of first unit head, 2 belows has second unit head 5; Be rotatably equipped with interior swivel nut (not marking among the figure) in second unit head 5 with internal thread by drive power source; Interior swivel nut cooperates formation screw, lead-screw drive mechanism with the helical blade of drilling rod 4 corresponding sites through the screw thread transmission, and drilling rod 4 is equivalent to the leading screw in screw, the screw mechanism, and the interior swivel nut of second unit head 5 is equivalent to the screw in screw, the screw mechanism.Be provided with in said swivel nut between the column 1 and second unit head 5 and said second unit head 5 moved spacing position-limit mechanism along column 1 bearing of trend when drilling direction creeps into driving said drilling rod 4 under the drive of power source, position-limit mechanism is the loading cylinder that cooperates with 5 push-and-pulls of second unit head that is arranged between column 1 and second unit head 5.The lower end fixed installation of second unit head 5 is useful on the aperture of when boring, going deep into corresponding stake hole and sentences the casing 6 that stops the stake hole to cave in.First unit head 2 is provided with first hydraulic motor, and the clutch end of the power intake of said first unit head 2 and first hydraulic motor is in transmission connection; Described second unit head 5 is provided with second hydraulic motor, and described second hydraulic motor is and drives the power source that said interior swivel nut rotates.Part 9 expression driver's cabins among the figure, part 3 expression sliding supports.In other embodiment of the utility model, when a stake hole ground that creeps into when needs was difficult for caving in, the structure of casing 6 can also not have; Can also to be pivot center be articulated in the catch on the column along the bearing of trend of column 1 to certain described position-limit mechanism; When needs move when spacing second unit head 5; The swing catch compresses second unit head 5; When not moving when spacing second unit head 5, the swing catch makes catch not influence the slip of second unit head 5 along column 1 bearing of trend.
During work; First unit head 2 provides driving torque for drilling rod; The interior swivel nut of second unit head 5 applies the downward power of creeping into through cooperating to drilling rod 4 with the helical blade screw thread transmission of drilling rod 4 peripheries, and drilling rod 4 creeps into the reinforcement of power, has improved the stake hole efficient of long helical deep hole rig; Simultaneously because casing 6 has guaranteed the stake Kong Buhui hole situation of collapsing; Use the corresponding unit head of fluid motor-driven, realize the high pulling torque construction of corresponding unit head, after corresponding unit head stops to bore unusually, also restart unit head more easily.Owing to need not increase the weight of first unit head 2, can not increase the moment of torsion of tumbling of 2 pairs of workbench 8 of first unit head simultaneously, guarantee the stability of deep hole long-spiral drilling machine.
