All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1 to 4, an embodiment of the present application provides a power head, which is applicable to a rotary drilling rig, and includes: a reduction box 1, wherein the reduction box 1 is used for accommodating and mounting components connected with an output shaft of a speed reducer 5 (the speed reducer 5 is a component of a power head and is described in detail later); the transmission part 2 is arranged in the reduction gearbox 1, particularly arranged in the reduction gearbox 1 in a mode of enabling the transmission part to rotate around the axis of the transmission part, and used for receiving power transmitted from the reduction gearbox 5; when the transmission element 2 is arranged in the reduction gearbox 1, one end of the transmission element 2 extends out of the reduction gearbox 1 (since the transmission element 2 has a smaller part located outside the reduction gearbox 1, the 'transmission element 2 is arranged in the reduction gearbox 1' mentioned in the application can be understood as that the larger part of the transmission element 2 is arranged in the reduction gearbox 1, or the main body structure of the transmission element 2 is arranged in the reduction gearbox 1, and the sun wheel 33 is also used as a first power output end which is used for driving a drill rod 8 of a rotary drilling rig; the power head further comprises a torque increasing mechanism 3, when the torque increasing mechanism 3 is arranged on the power head, the torque increasing mechanism 3 is arranged inside the reduction gearbox 1, namely the torque increasing mechanism 3 and the power head are integrated into a whole, so that the torque increasing mechanism 3 becomes a component of the power head, when the torque increasing mechanism 3 is arranged in the reduction gearbox 1, the torque increasing mechanism 3 is connected with the transmission piece 2, the transmission piece 2 transmits power to the torque increasing mechanism 3, the power is output from a second power output end extending out of the torque increasing mechanism 3 to the outside of the reduction gearbox 1 after being decelerated and torque increased by the torque increasing mechanism 3, and the second power output end is used for driving a protective cylinder 9 of the rotary drilling rig.
Foretell unit head increases to turn round mechanism 3 through addding to make and increase to turn round mechanism 3 and unit head integration be a whole, not only can increase the output torque of unit head, satisfy the demand of protecting a section of thick bamboo construction entirely, but also can simplify the structure through the mode of integrated setting, avoid the dismouting, brought the facility for the management and control and the transportation of machine.
In an alternative embodiment, the application also provides that the second power take-off and the transmission 2 rotate in opposite directions. In practical use, the power head is arranged on the mast 7 of the rotary drilling rig to drive the drill rod 8 and the casing 9 to rotate, the mast 7 is used as a component for arranging and supporting the power head, and in the process of drilling the ground by the drill rod 8, the power head exerts an acting force on the mast 7 in a direction opposite to the rotating direction of the drill rod 8, so that the balance stability of the rotary drilling rig is influenced. So in order to promote the job stabilization nature of digging the rig soon, this application makes the rotation direction of second power take off end and driving medium 2 reverse, that is to say make the rotation direction of second power take off end and first power take off end opposite, so just can make the rotation direction of protecting section of thick bamboo 9 and drilling rod 8 opposite, during synchronous construction, the counter-rotating protects section of thick bamboo 9 and drilling rod 8 and can offset the respective reaction force that produces each other, make the reaction force that mast 7 bore reduce or even disappear, and then make the job stabilization nature of digging the rig soon and obtain showing and promote. Specifically, the structure for realizing the reverse rotation of the second power output end and the transmission member 2 is described later.
As shown in fig. 2 and 4, the torque increasing mechanism 3 is preferably a planetary gear mechanism, and the ring gear 31 of the planetary gear mechanism is fixedly arranged on the reduction gearbox 1, for example, the ring gear 31 can be arranged on the inner wall of the reduction gearbox 1 or directly arranged as a partial circumferential side wall of the reduction gearbox 1, the planet carrier 32 of the planetary gear mechanism is a power input part of the planetary gear mechanism connected with the transmission part 2, and the sun gear 33 of the planetary gear mechanism is a power output part of the planetary gear mechanism. The torque increasing mechanism 3 is set to be a planetary gear mechanism, because when the full-protection barrel construction is carried out, the protection barrel 9 and the drill rod 8 are required to be sleeved, the planetary gear mechanism is an assembly with a central axis (namely, the axis of the sun gear 33), so that the planetary gear mechanism can be conveniently and coaxially arranged with the transmission part 2, and the planetary gear mechanism can be better matched with the power head and other components of the rotary drilling rig as the component part of the power head, namely, the coaxial arrangement of the drill rod 8 driven by the transmission part 2 and the protection barrel 9 driven by the planetary gear mechanism is realized, so that the power head and the rotary drilling rig are more compact in structure and higher in working stability. In addition, the torque increasing mechanism 3 may have other structures, such as a large gear or a large ring gear with more teeth engaged with the gear on the transmission member 2.
On the basis that the torque increasing mechanism 3 is a planetary gear mechanism, as shown in fig. 4, a planet carrier 32 of the planetary gear mechanism is further used as a power input member, a sun gear 33 is used as a power output member, and a ring gear 31 is fixedly arranged on the inner wall of the reduction gearbox 1. Specifically, the planet carrier 32 is connected with the transmission member 2, for example, the planet carrier 32 is fixedly connected to the transmission member 2 by bolts, so as to realize synchronous rotation of the planet carrier 32 and the transmission member 2, the sun gear 33 realizes rotation arrangement in the reduction gearbox 1 and transmission of a pressure force with the planet carrier 32 through the slewing bearing 14 arranged between the sun gear 33 and the bottom wall of the reduction gearbox 1 and between the sun gear 33 and the planet carrier 32, and meanwhile, in order to ensure normal rotation and matching of the planet carrier 32 and the sun gear 33, planet gears arranged on the planet carrier 32 are meshed with the gear ring 31 and the sun gear 33. When the power head works, the transmission piece 2 drives the planet carrier 32 as a power input piece to rotate, and the gear ring 31 is fixed on the reduction gearbox 1, so that the sun gear 33 as a power output piece is driven to rotate under the meshing transmission of the planet gear, the gear ring 31 and the sun gear 33. The torque transmitted from the transmission part 2 is amplified through the speed reduction meshing transmission of the gear ring 31, the planet wheels and the sun wheel 33 so as to achieve the purposes of speed reduction and torque increase.
In the case where the reaction force applied to the mast 7 is not considered, that is, the reaction force applied to the mast 7 is not reduced or eliminated, the planetary gear mechanism may adopt a conventional power transmission manner, that is, a plurality of planetary gears provided on the carrier 32 do not interfere with each other, and each planetary gear working independently meshes with the ring gear 31 and the sun gear 33, and at this time, the carrier 32 as the power input member and the sun gear 33 as the power output member rotate in the same direction. When it is desired to reduce or eliminate the reaction force applied to the mast 7, the planetary gear mechanism can be improved as follows.
As shown in fig. 2, a plurality of planetary gear sets are circumferentially arranged on the planet carrier 32, each planetary gear set includes a first planet gear 34 and a second planet gear 35 which are rotatably arranged on the planet carrier 32 and are meshed with each other, the first planet gear 34 is meshed with the ring gear 31, and the second planet gear 35 is meshed with the sun gear 33. In each planetary gear set, the outer side of the first planetary gear 34 far from the sun gear 33 is meshed with the ring gear 31, the inner side of the first planetary gear 34 near the sun gear 33 is meshed with the second planetary gear 35, the outer side of the second planetary gear 35 far from the sun gear 33 is meshed with the first planetary gear 34, and the inner side of the second planetary gear 35 near the sun gear 33 is meshed with the sun gear 33. In the working process, if the sun gear 33 rotates clockwise, the second planet gear 35 meshed with the sun gear 33 rotates anticlockwise, and the first planet gear 34 meshed with the second planet gear 35 also rotates clockwise, because the gear ring 31 is fixed on the reduction gearbox 1, the first planet gear 34 rotating clockwise can drive the planet carrier 32 to rotate anticlockwise, so that the reverse rotation of the planet carrier 32 and the sun gear 33 is realized, and therefore when the transmission piece 2 fixedly connected with the planet carrier 32 drives the drill rod 8 to rotate in the forward direction, the sun gear 33 drives the protective sleeve 9 to rotate in the reverse direction, so that the reaction force borne by the mast 7 can be reduced or eliminated. In this structure, in order to ensure that the speed reduction and torque increase effects of the planetary gear mechanism are not changed, it is preferable that the first planet gears 34 and the second planet gears 35 are gears of the same type, the axes of the first planet gears 34 of all the planetary gear sets are all located on the first circle 12, the axes of the second planet gears 35 of all the planetary gear sets are all located on the second circle 13, the centers of the first circle 12 and the second circle 13 are all the axes of the sun gear 33, and the radius of the first circle 12 is greater than that of the second circle 13, as shown in fig. 2.
In addition, other modes can be adopted to realize the reverse rotation, for example, a gear is arranged on the transmission piece 2, a gear coaxial with the planet carrier 32 is also fixedly arranged on the planet carrier 32, the two gears are meshed with each other, the reverse rotation of the drill rod 8 and the protective cylinder 9 is realized by the principle of meshing gears to rotate in reverse, and the planetary gear mechanism can adopt the traditional power transmission mode. On the basis, in order to realize the normal sleeving of the casing 9 on the drill rod 8, the casing 9 can have a large enough inner diameter, and the drill rod 8 is positioned at an eccentric position in the casing 9.
In the present application, as shown in fig. 3 and 4, the transmission member 2 is a sleeve having a through inner cavity; the planet carrier 32 is a coaxial ring-shaped frame fixed at the bottom end of the sleeve, the sun gear 33 is a hollow gear coaxially arranged at the bottom side of the sleeve, and one end of the sun gear 33 far away from the sleeve is a second power output end. The transmission part 2, the planet carrier 32 and the sun gear 33 with the structure can enable the drill rod 8 to penetrate through the transmission part, so that the transmission part is beneficial to being matched with the drill rod 8, and compared with a mode that the drill rod 8 is arranged outside the transmission part, the transmission part is more compact in arrangement, and the size of the power head is reduced. Further, when the drill rod 8 penetrates through the transmission part 2, the planet carrier 32 and the sun gear 33, the drill rod 8, the transmission part 2, the planet carrier 32, the sun gear 33 and a sheath connected with the sun gear 33 are coaxially arranged, so that the stress balance of each part is improved, and the power head and the rotary drilling rig can work more reliably. Furthermore, the transmission 2, the planet carrier 32 and the sun gear 33 may also be solid parts, with the drill rods 8 arranged parallel on their sides.
In particular, the planet carrier 32 is provided with a connecting column extending parallel to the transmission element 2 towards the bottom side of the transmission element 2, so that the first planet wheel 34 and the second planet wheel 35 arranged thereon can be arranged at the same height as the sun wheel 33 and the ring gear 31, thereby ensuring the normal meshing of the first planet wheel 34 and the ring gear 31 and the normal meshing of the second planet wheel 35 and the sun wheel 33.

Because planet carrier 32 has connected the bottom at driving medium 2, sun gear 33 has set up the bottom side at driving medium 2, so this application makes the top of driving medium 2 be the first power take off end that is used for to drilling rod 8 output power to through key sleeve barrel 4 and drilling rod 8 circumferential direction location (because drilling rod 8 need bore into the underground, drilling rod 8 need carry out axial displacement promptly, so connect drilling rod 8 and driving medium 2 key sleeve barrel 4 only with drilling rod 8 circumferential direction location, in order to guarantee can also normally drive drilling rod 8 rotatory when not influencing drilling rod 8 axial and move down).
