Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 3, Fig. 3 is the schematic diagram of a kind of embodiment of the unit head of truck-mounted drilling rig provided by the invention.
As shown in Figure 3, the invention provides a kind of unit head 100, it comprises slip portion 102 and motor 101, and slip portion 102 is for holding drill pipe, and motor 101 drives slip portion 102 to rotate, and slip portion 102 rotates and drives drilling rod to rotate.Wherein, motor 101 is four, and these four motors 101 one group are arranged on the relative both sides that axis installed by drilling rod between two, and are all connected with slip portion 102 gear, and synchronously drive slip portion 102 to rotate.
Only design two motors 101 in prior art and drive slip portion 102, often occur that the moment of torsion provided is not enough, and the situation of the task of creeping into cannot be completed, the present invention also rationally arranges the position of each motor by the number increasing motor 101, and each motor synchronous rotates as slip portion 102 provides enough moments of torsion.
Unit head 100 is by increasing motor 101 number and arranging the more moment of torsion of corresponding position acquisition, be not subject to motor 101 and arrange quantitative limitation, even if single-motor 101 discharge capacity is not enough, also can obtain larger total displacement by multiple motor 101, and be adapted to the work requirements that heavy caliber creeps into; In addition, the motor 101 increased all is connected with slip portion 102 gear with original each motor 101, and slip portion 102 is for after former motor 101 installation, its circumference must also have more installing space, the each motor 101 being about to increase is arranged on slip portion 102 with reference to existing motor 101, and compared to installing gearbox additional, the increase height of unit head 100 or drilling rod be not to the center to center distance of mast, after installing with truck-mounted drilling rig, do not affect whole vehicle stability.
And each group motor 101 pairs of slip portions 102 apply active force, and be provided to drilling rod further, in this arrangement form, the application point of active force to drilling rod is symmetrical, not only be conducive to stability under loading in rod boring process, the active force also making each motor 101 provide promotes mutually, avoiding unstable transmission to form loss, is very favourable to effective utilization of creeping into power.
Above-mentioned installation axis refers to that drilling rod is arranged on after on unit head 100, and drill rod axis place place, as Fig. 3, illustrates drilling rod installation position 200, and it is installed for coordinating with drilling rod.
The application does not limit the concrete setting position of each motor 101, as long as can provide moment of torsion that is stable, that can rotate for it for drilling rod.Such as, the more motor 101 of number also can be set, and in the appropriate location in slip portion 102, motor 101 be installed.
Further, the application does not also limit the concrete shape in slip portion 102, as long as it can holding drill pipe provide installation site for motor 101.
Further, each motor 101 can be gerotor motor 101, and gerotor motor 101 is hydraulic motors 101 of a kind of small-sized, low speed, high pulling torque of internal messing cycloidal gear type, and its structure is simple, low-speed performance good.So, the superperformance that gerotor motor 101 low speed can be utilized to have, obtain high pulling torque better, and its size is less, is also conducive to reducing unit head 100 size further.
In above-mentioned each scheme, slip portion 102 towards the sidepiece of motor 101 one-body molded be provided with gear teeth, correspondingly, the output shaft of motor 101 should overlap have can with gear teeth meshed gears, so, realize motor 101 to be connected with the gear in slip portion 102.
By gear teeth and slip portion 102 one-body molded, after can effectively avoiding slip portion 102 and motor 101 to assemble, start the relative displacement produced between gear teeth portion and slip portion 102 main body instantaneously delayed, can quick, the gear teeth that rapidly driving torque that motor 101 exports is passed to slip portion 102, and then act on drilling rod, finally improve the drilling efficiency of drilling rod and creep into accuracy.
Certainly, also can adopt the connected mode of being assembled with gear split in slip portion 102, just, may there is gear and be connected unstable problem with slip portion 102 in this connected mode, for the present embodiment is then more stable, firm.
The present invention also provides a kind of truck-mounted drilling rig, and comprise the unit head 100 of drilling rod and this drilling rod of clamping, this unit head 100 is the unit head 100 described in the respective embodiments described above.
Choosing of drilling rod can with reference to prior art, as long as the type of attachment of drilling rod and unit head 100 can make unit head 100 to drilling rod transmitting torque and axial compression.
Owing to having the unit head 100 in the respective embodiments described above, therefore, this truck-mounted drilling rig has identical beneficial effect with above-mentioned unit head 100.
In a further embodiment, the sidepiece of unit head 100 holding drill pipe can also be provided with internal thread, correspondingly, drilling rod is provided with the external screw thread with this screw-internal thread fit towards the side of unit head 100, drilling rod and slip portion 102 form screw thread pair, and this screw thread pair will act on the force transmission in slip portion 102 to drilling rod.
Unit head 100 operationally, is subject to downward pressure, and further by screw thread pair, above-mentioned pressure is passed to drilling rod under the effect of pressurization wire rope, and plus-pressure makes drilling rod creep into object to rock etc. to creep into.
The axis that the action direction of above-mentioned pressure is threadingly secondary, screw thread pair is when being subject to axial force, excellent mechanical property can be shown, generally can stablize between screw thread and lock securely, and, this assembling mode is very simple, contributes to the installation effectiveness improving drilling rod and unit head 100.
Certainly, drilling rod and slip portion 102 can also have other types of attachment, such as, and clamping, welding etc.
Above a kind of truck-mounted drilling rig provided by the present invention and unit head thereof are described in detail.Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
