Some embodiments of the present invention provide a drilling device and a drilling apparatus, wherein the drilling apparatus includes an apparatus main body, the apparatus main body is provided with an arm support, and the drilling device is arranged on the arm support of the drilling apparatus. Before drilling, the arm support is moved to a proper position, then the drill rod is connected with the drilling device, the drilling device drives the drill rod to advance to realize drilling, and after the drilling is finished, the drilling device drives the drill rod to retreat to enable the drill rod to exit from the drilling. Namely, the drilling device provided by the embodiment of the invention is matched with the drill rod, and the drilling device pushes the drill rod to realize the punching operation. In the drilling device used in cooperation with the hexagonal drill rod in the related art, a hexagonal connecting hole is usually formed in an output shaft of the propeller, and the hexagonal connecting hole and the hexagonal outer surface of the hexagonal drill rod are limited to drive the drill rod to rotate, namely the output shaft is not directly connected with the drill rod, but the output shaft drives the drill rod to rotate through a limiting relation. Such setting drives the drilling rod at the propeller and withdraws from the in-process of drilling, because the drilling rod need not rotate, and at this moment, the hexagon surface of hexagon connecting hole and hexagonal drilling rod need not spacing, consequently, because output shaft and drilling rod do not have lug connection and have the phenomenon that the drilling rod card dies can't extract in drilling, influence the efficiency of construction greatly.

A drilling apparatus and a drilling device provided according to some embodiments of the present invention will be described below with reference to fig. 1 to 6.

In view of the above, an embodiment of the first aspect of the present invention provides a drilling apparatus, comprising: the propeller 120, the output shaft 121 of the propeller 120 is provided with a thread to which the drill rod 160 is connected.

The drilling device provided by the embodiment of the present invention, as shown in fig. 1, is used in cooperation with a hexagonal drill rod, that is, the drill rod 160 shown in fig. 1 is a hexagonal drill rod, and it is to be understood that the drilling device provided by the embodiment of the present invention may also be used in cooperation with an octagonal drill rod, or other drill rods that meet the requirement. The drilling apparatus includes a base assembly 110 and a pusher 120, wherein the base assembly 110 is coupled to a boom of the drilling apparatus and the pusher 120 is slidably coupled to the base assembly 110, it being understood that the pusher 120 may be a drilling machine, a rock drill, or other structure that meets the requirement that the pusher 120 be slidable along the base assembly 110 to advance the drill rod 160 to effect drilling or to guide withdrawal of the drill rod 160 from the borehole. The output shaft 121 of the propeller 120 is provided with threads connected with the drill rod, namely, the output shaft 121 of the propeller 120 is in threaded connection with the drill rod, and with such an arrangement, when drilling is completed, the propeller 120 drives the drill rod 160 to exit from the drilling process, the drill rod 160 is still in threaded connection with the output shaft 121 of the propeller 120, which does not have a drilling device as in the related art.

Further, the output shaft 121 of the propeller 120 is provided with a thread connected with the drill rod 160, wherein the thread may be an internal thread or an external thread, specifically, the output shaft 121 may be provided with an internal thread, and the drill rod is provided with an external thread matched with the internal thread; alternatively, an external thread may be provided on the output shaft 121, and the drill rod may be provided with an internal thread adapted to the external thread. Different arrangement modes of the threads can meet the requirements of different structures of the output shaft 121 and different structures of the drill rod 160, and the application range of products is enlarged.

Further, as shown in fig. 2 and fig. 3, the propeller 120 is slidably connected to the base assembly 110 through the mounting frame 170, that is, the propeller 120 is mounted on the mounting frame 170, the base assembly 110 is provided with a slide rail, the mounting frame 170 is provided with a slide block adapted to the slide rail, and the slide block is slidably connected to the slide rail, so that the mounting frame 170 is slidably connected to the base assembly 110, and the propeller 120 can slide along the base assembly 110. It is understood that the pusher 120 may be slidably coupled to the base assembly 110 by other structures as desired, and the invention is not limited in this regard.

In some possible embodiments of the present invention, the drilling apparatus further comprises a gripping mechanism 130, it being understood that the gripping mechanism 130 is for gripping the drill rod 160. As shown in fig. 4 and 5, the clamping mechanism 130 includes a mounting seat 131, a supporting arm 132, a clamping jaw 133, and a first driving mechanism 134, wherein the mounting seat 131 is disposed on the base assembly 110, the supporting arm 132 is rotatably connected to the mounting seat 131, the supporting arm 132 includes a clamping end and a driving end that are oppositely disposed, the clamping end is provided with an open slot 1321 that can accommodate the drill rod 160 and limit the rotation of the drill rod 160, and the clamping jaw 133 is rotatably connected to the supporting arm 132 and can open and lock the open slot 1321. Specifically, when the clamping jaw 133 rotates relative to the supporting arm 132 to open the open slot 1321, the drill rod 160 can be accommodated in the open slot 1321 or taken out of the open slot 1321, and when the clamping jaw 133 rotates relative to the supporting arm 132 to lock the open slot 1321, the clamping jaw 133 stops the drill rod 160 in the open slot 1321 to ensure the safety of the transportation of the drill rod 160. Further, when the clamping jaw 133 rotates to the buckling open slot 1321 relative to the supporting arm 132, the clamping jaw 133 can also clamp the drill rod 160, and at this time, if the drill rod 160 is connected with the output shaft 121, the drill rod 160 can be separated from the output shaft 121 by reversely rotating the output shaft 121, so that the automatic disassembly of the drill rod 160 and the output shaft 121 is realized, the operation of manually separating the drill rod 160 from the output shaft 121 is simplified, and the using satisfaction of a user is improved.

The first driving mechanism 134 is connected to the mounting seat 131 and the driving end of the supporting arm 132, and can drive the supporting arm 132 to rotate relative to the mounting seat 131 to make the clamping end close to and far away from the axis of the output shaft 121, so as to facilitate the installation and the removal of the drill rod 160 and the output shaft 121 of the propeller 120.

Specifically, when the drill rod 160 needs to be connected to the pusher 120, the drill rod 160 is first installed in the open slot 1321 of the supporting arm 132, and the clamping jaw 133 is rotated relative to the supporting arm 132 and is buckled with the open slot 1321, so as to ensure the stability of the drill rod 160 during the movement process. Then, the first driving mechanism 134 is operated to drive the holding end of the supporting arm 132 to rotate toward the axial direction close to the output shaft 121, so that the axial line of the drill rod 160 coincides with the axial line of the output shaft 121, then, the pusher 120 slides along the base assembly 110 to a proper distance toward the drill rod 160, and then the output shaft 121 of the pusher 120 rotates forward, so that the drill rod 160 is screwed with the output shaft 121 of the pusher 120, thereby achieving the installation of the drill rod 160.

When the drill rod 160 is connected to the pusher 120, the jaws 133 may be positioned to open the open slots 1321. In order to avoid the influence of the closer distance between the supporting arm 132 and the axis of the output shaft 121 on the sliding range of the thruster 120 along the base assembly 110, the first driving mechanism 134 may be used to drive the clamping end of the supporting arm 132 to rotate away from the axis of the output shaft 121, so that the drill rod 160 can be separated from the open slot 1321, and the distance between the clamping end of the supporting arm 132 and the axis of the output shaft 121 is longer, so as to ensure that the thruster 120 has a larger propelling space.

During drilling, the pusher 120 slides along the base assembly 110 in a direction close to the working surface, and the pusher 120 rotates forward and drives the drill rod to rotate, so as to push the drill rod to realize drilling operation. Wherein, the working face can be a rock wall or a roadway inner wall.

When the drilling thruster 120 slides to the end far away from the rock wall or the inner wall of the roadway along the base assembly 110 to take the drill rod 160 out of the drilled hole, at this time, the first driving mechanism 134 can drive the clamping end of the supporting arm 132 to rotate towards the direction close to the axis of the output shaft 121, the drill rod 160 is accommodated in the open slot 1321, the clamping jaw 133 rotates to close the open slot 1321, the drill rod 160 is clamped or the drill rod 160 is circumferentially limited to limit the rotation of the drill rod, and then the operation of separating the drill rod 160 from the output shaft 121 of the thruster 120 can be performed. For example, when the clamping jaws 133 clamp the drill rod 160, the main shaft of the pusher 120 is reversed (i.e., reversed), which drives the connecting threads of the drill rod 160 and the output shaft 121 to unscrew and completely disengage, thereby effecting separation of the drill rod 160 and the output shaft 121. Further, after the drill rod 160 is separated from the output shaft 121, the first driving mechanism 134 drives the clamping end of the supporting arm 132 to rotate in the axial direction away from the output shaft 121, so as to drive the drill rod 160 to move away from the output shaft 121, thereby completing the operation of removing the drill rod 160. It is understood that the first driving mechanism 134 includes a cylinder, or other driving mechanism that meets the requirements, and the present invention is not particularly limited.

Further, the drilling device further comprises a second driving mechanism 135, and the supporting arm 132 further comprises a connecting end located between the driving end and the clamping end, the connecting end is provided with a third shaft 139, wherein one end of the second driving mechanism 135 is hinged with the third shaft 139, and the other end is hinged with the clamping jaw 133, and can drive the clamping jaw 133 to rotate relative to the supporting arm 132 to open or buckle the open slot 1321. It is understood that the second driving mechanism 135 includes a cylinder, or other driving mechanism satisfying the requirement, and the present invention is not particularly limited.

That is to say, the clamping mechanism 130 provided in the embodiment of the present invention can realize connection and detachment of the drill rod 160 and the output shaft 121, and solve the problem that the labor cost for manually installing and detaching the drill rod is high in the related art, and the problem that the construction difficulty for manually installing and detaching the drill rod 160 is high when the position of the output shaft 121 is high, thereby reducing the labor cost and the construction difficulty, improving the construction safety, and being suitable for popularization and application.

Further, as shown in fig. 4, the inner wall of the open slot 1321 includes two limiting surfaces 1322 that are oppositely disposed, the axial cross section of the drill rod 160 is a first hexagon, that is, the drill rod is a hexagonal drill rod, the distance between the two limiting surfaces 1322 is greater than the opposite side distance of the first hexagon and smaller than the opposite side distance of the first hexagon, in the process that the output shaft 121 rotates reversely to drive the drill rod 160 to disengage from the output shaft 121, the two limiting surfaces 1322 can limit the outer surface of the hexagonal drill rod 160, that is, the two limiting surfaces 1322 can limit the rotation of the hexagonal drill rod 160, and further when the output shaft 121 rotates reversely, the drill rod 160 does not rotate along with the output shaft 121, so that the drill rod 160 is disengaged from the output shaft. Namely, under the action of the two limiting surfaces 1322, the output shaft 121 rotates reversely, so that the output shaft 121 and the hexagonal drill rod 160 can be quickly and reliably separated from each other at the connecting thread, and the construction efficiency is further ensured.

Further, because the output shaft 121 of the propeller 120 is connected with the drill rod 160 through threads, when the drill rod 160 is disassembled, the drill rod 160 can be reliably disassembled without being clamped in the output shaft 121, so that the disassembling efficiency is further improved, and the construction efficiency is improved.

Specifically, since the axial cross section of the hexagonal drill rod is hexagonal, the two limiting surfaces 1322 may be connected to the inside of the open slot 1321 through a curved surface, or the two limiting surfaces 1322 may be connected to the inside of the open slot 1321 through a bent surface, so as to ensure that the hexagonal drill rod 160 can be accommodated in the open slot 1321. Specifically, the axial cross section of the open slot 1321 is a partial hexagon, and the planes of two opposite sides in the partial hexagon are the two limiting surfaces 1322.

Further, the opening of the open slot 1321 is provided with a guide surface 1323 connected with the limiting surface 1322, and the two guide surfaces 1323 can guide the drill rod 160 to rapidly and reliably enter the open slot 1321, so that the mounting and dismounting efficiency of the drill rod 160 and the output shaft 121 of the propeller 120 is improved. Specifically, the distance between the ends of the two guide surfaces 1323 connected to the limiting surface 1322 is greater than the distance between the other ends of the two guide surfaces 1323, that is, the two guide surfaces 1323 are arranged, so that the open slot 1321 is in a flaring structure, and the drill rod 160 can conveniently enter the open slot 1321.

In some possible embodiments of the present invention, the drilling apparatus further includes a positioning member 136, and the positioning member 136 is provided with a connecting groove and a limiting groove 1361 at intervals. The mounting seat 131 is provided with a first shaft 137 penetrating through the connecting groove, the driving end of the supporting arm 132 is provided with a second shaft 138 penetrating through the limiting groove 1361, namely, the positioning element 136 can be rotatably connected with the mounting seat 131 through the connecting groove and the first shaft 137 in a matching manner, and the positioning element 136 can be rotatably connected with the driving end of the supporting arm 132 through the limiting groove 1361 and the second shaft 138 in a matching manner. Because one end of the first driving mechanism 134 is hinged to the first shaft 137, the other end of the first driving mechanism 134 is hinged to the second shaft 138, and the first driving mechanism 134 can drive the second shaft 138 to slide in the limiting groove 1361, because the limiting groove 1361 is a long-strip groove and the length of the limiting groove 1361 is a certain value, the limiting groove 1361 can limit the rotation angle of the supporting arm 132, and ensure that the supporting arm 132 rotates to a proper position, so that the axis of the drill rod 160 coincides with the axis of the output shaft 121, and the working reliability of the device is improved. Specifically, a straight line in which the length direction of the elongated groove is located is parallel to the axial cross section of the output shaft 121, i.e., a plane in which the length direction of the elongated groove is located is perpendicular to the axis of the output shaft.

Further, as shown in fig. 4, the mounting seat 131 includes two opposite side plates 1311, and a connecting plate 1312 connecting the two side plates 1311, wherein the side plates 1311 are L-shaped, the L-shaped side plates include a first plate 1313 and a second plate 1314 connected to each other, the connecting plate 1312 is connected to the two first plates 1313, and the support arm 132 and the first shaft 137 are connected to the two second plates 1314. It will be appreciated that the attachment plate 1312 is coupled to the base assembly 110 to mount the entire clamping mechanism 130 to the base assembly 110. Further, in order to improve the strength of the mount 131, a reinforcing plate connecting the two second plates 1314 may be further provided to improve the reliability of the mount 131.

As shown in fig. 5, the supporting arm 132 includes two arm bodies 1324 and a connecting portion 1325, the two arm bodies 1324 are disposed opposite to each other, and the first ends 1326 of the two arm bodies 1324 are connected by the connecting portion 1325 to form a clamping end of the supporting arm 132, wherein the connecting portion 1325 is provided with a receiving groove, the first ends 1326 of the two arm bodies 1324 are provided with an open groove 1321, and the open groove 1321 of the two arm bodies 1324 is communicated with the receiving groove to receive a drill rod. The second ends 1327 of the two arms 1324 are coupled by a second shaft 138 to form a drive end of the support arm 132, it being understood that the first end 1326 and the second end 1327 are located at opposite ends of the arm 1324. The portion of the arm 1324 between the first end 1326 and the second end 1327 is provided with a protruding structure forming a third end 1328 of the arm 1324, the third ends 1328 of the two arms 1324 being connected by a third shaft 139 to form a connecting end. One arm 1324 is hinged to one second plate 1314 of the mounting block 131, and the other arm 1324 is hinged to the other second plate 1314 of the mounting block 131, so as to rotatably mount the support arm 132 on the mounting block 131. Since the first driving mechanism 134 connects the first shaft 137 and the second shaft 138, the two arms 1324 can be driven to rotate relative to the mounting seat 131 at the same time.

Further, the clamping jaws 133 are hinged to the first ends 1326 of the two arms 1324, and the second driving mechanism 135 connects the clamping jaws 133 to the third shaft 139, so that the clamping jaws 133 can be driven to rotate to open and lock the open slots 1321 and the receiving slots.

In some possible embodiments provided by the present invention, as shown in fig. 3, an end surface of the output shaft 121 is provided with a connecting hole 122 extending along an axial direction, specifically, an end portion of the output shaft 121 for connecting with the drill rod 160 is an output end, an end surface of the output end is provided with the connecting hole 122 along the axial direction, the connecting hole 122 includes a first portion 123, a thread is disposed in the first portion 123, that is, the output shaft 121 is provided with an internal thread, and the drill rod 160 is in threaded connection with the output shaft 121 through the internal thread, it can be understood that the drill rod 160 is provided with an external thread matching with the internal thread.

Further, the connection hole 122 includes a first portion 123, a second portion 124, and a third portion 125 sequentially distributed in the axial direction, that is, the third portion 125 is located at the outermost side of the connection hole 122. The third portion 125 is used to connect an anchor rod or other component to enable the anchor rod or other component to be installed and removed using the output shaft 121, thereby extending the range of use of the drilling apparatus. Specifically, when the drill rod 160 is a hexagonal drill rod, the axial cross section of the hexagonal drill rod is a first hexagon, the axial cross section of the third portion 126 of the connecting hole 122 is a second hexagon, and the distance between opposite sides of the second hexagon is greater than the diagonal distance of the first hexagon, such an arrangement can ensure that the hexagonal drill rod is smoothly connected with the thread built in the first portion 123 through the third portion 126 of the connecting hole 122. Meanwhile, the axial section of the third portion 126 is a second hexagon, and other parts (such as a hexagonal anchor rod and a hexagonal nut) matched with the second hexagon can be limited by the second hexagon, so that the output shaft 121 is used for mounting and dismounting other parts, and the application range of the drilling device is expanded. For example, the nut of screwing up of shrouding is hexagon nut, matches the overall dimension of the nut of screwing up of the size and the fixed shrouding of second hexagon, and then utilizes the third part 125 of the connecting hole 122 of output shaft 121, can realize the installation and the dismantlement of the nut of screwing up of shrouding, convenient operation.

Further, the first portion 123 and the third portion 125 are spaced apart from each other, that is, the first portion 123 and the third portion 125 are communicated with each other through the second portion 124, so that the arrangement can prevent the connecting bolt from damaging the internal thread of the first portion 123 when the nut is detached and installed through the hexagonal connecting hole of the third portion 126, and further protect the internal thread of the first portion 123, so as to ensure the reliability of the threaded connection between the output shaft 121 and the drill rod 160.
