Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drilling machines, in particular to a percussion and vibration drilling tool and a multifunctional drilling machine. BACKGROUND

[0002] In the prior art, large-diameter drilling operations mainly adopt two ways of cutting drilling and percussion drilling.

[0003] The drilling machines commonly used for cutting drilling are mud reverse circulation drilling machines, rotary drilling machines and screw drilling machines. These drilling machines have high drilling efficiency for sandy soil layers in good conditions, but it is very difficult to drill in hard rock layers, especially for reverse circulation drilling machines to drill in complex strata such as backfill soil layers containing super-diameter stones. The drilling depth of rotary drilling machines and screw drilling machines is limited due to their own design reasons.

[0004] For drilling in complex strata and hard rock layers, the most effective way is percussion drilling. The commonly used percussion drill can be called a "universal drill", which can drill in any strata, but the drilling efficiency is too low. The pneumatic down-the-hole drill is a high-efficiency small-diameter rock drilling machine, but due to the influence of factors such as air distribution and slag return, it is difficult to form a hole and the cost is high when used for large-diameter rock drilling. The rotary drilling machine and the reverse circulation drilling machine are installed with a cluster type down-the-hole hammer, which is also difficult due to the influence of air supply mode.

[0005] The top drive vibration method is simple and easy to operate, but it cannot meet the requirements of deep drilling due to the energy loss of the drill pipe.

[0006] Therefore, the drilling machines in the prior art have their own advantages and disadvantages in drilling applications, and sometimes a single drilling machine cannot achieve high-efficiency drilling in complex drilling environments, which requires changing the type of drilling machine according to the actual situation, thus wasting time and effort.

[0100] The shock drill provided in the embodiment includes a transmission device, a first movement device and a second movement device, and the connection relationship and working principle of the above-mentioned components will be described in detail below.

[0101] As shown in Figure 1 The transmission device can include a first transmission mechanism and a second transmission mechanism. In the embodiment, the first transmission mechanism can be formed as an inner drill rod 111, and the second transmission mechanism can be formed as an outer drill rod 113. Both of them can be formed with a hollow portion, that is, the inner drill rod 111 can be formed with an inner hollow portion 112, and the outer drill rod 113 can be formed with an outer hollow portion. Further, the inner drill rod 111 can be accommodated in the outer hollow portion of the outer drill rod 113, so that the outer wall of the inner drill rod 111 and the inner wall of the outer drill rod 113 can define a first conveying gap 114. The function of the first conveying gap 114 will be described later.

[0102] In an embodiment, the inner drill rod 111 and the outer drill rod 113 arranged in the above manner can be coaxially arranged, and the axes of the two can be defined as a first rotation axis, on the basis of which the inner drill rod 111 and the outer drill rod 113 can both rotate about the first rotation axis, and the driving mode of this rotation will be described in the subsequent description. Still referring to Figure 1 , the first movement device includes a first accommodating member 130, and as a preferred embodiment, the first accommodating member 130 can be formed in a substantially revolution body shape, and in the arrangement manner, the axis of the first accommodating member 130 can still be the aforementioned first rotation axis, and the structure of the first accommodating member 130 will be described in detail below.

[0103] As shown in Figure 1 , the first accommodating member 130 can include a flow guide portion, a main body portion and a connecting portion connected in sequence from top to bottom. The outer side of the flow guide portion can be formed in a circular truncated cone shape, and the upper end and the lower end thereof are both formed in an opening, and the upper opening of the flow guide portion can be connected with the outer drill rod 113, and specifically, a portion (hereinafter referred to as a sealing portion) of the outer drill rod 113 can extend into the space defined by the inner side of the flow guide portion via the upper opening, and it goes without saying that the inner drill rod 111 also penetrates the upper opening at the same time. Therefore, the aforementioned sealing portion and the inner drill rod 111 can be sealed via a wear-resistant ring or a sealing bearing, so that the first conveying gap 114 and the internal space of the first accommodating member 130 are isolated from each other.

[0104] The main body portion of the first accommodating member 130 can be formed in a cylindrical shape or a cylindrical shape with a polygonal cross section, and the cylindrical shape will be taken as an example for description below. The cylindrical main body portion can be connected with the lower opening of the aforementioned flow guide portion, so that the space defined by the inner side of the flow guide portion and the space defined by the inner side of the main body portion are communicated, and together form the interior of the first accommodating member 130. The lower end of the main body portion is closed and has a hole portion for the inner drill rod 111 to penetrate, and a wear-resistant sealing ring or a sealing bearing can be arranged between the outer side of the inner drill rod 111 and the inner edge of the hole portion, so as to provide support for the inner drill rod 111 when the inner drill rod 111 moves relative to the first accommodating member 130, and so that the aforementioned hole portion is sealed.

[0105] On this basis, the second movement device further comprises a second accommodating member 140, the shape of the whole of the second accommodating member 140 can be similar to the main body part of the aforementioned first accommodating member 130, and the upper end of the second accommodating member 140 can be formed with a second clamping part, and correspondingly, the connecting part of the aforementioned first accommodating member 130 can be formed as a first clamping part. Specifically, the first clamping part can be formed as a downwardly extending strip-shaped part, and the number thereof can be at least two. For one of the first clamping parts, the upper end and the lower end thereof can be respectively formed with a first limiting part and a second limiting part extending towards or substantially towards the first rotation axis, and the two limiting parts thereby define a clamping groove in the vertical direction. For the second clamping part, it can be formed on the outer side of the upper end of the second accommodating member 140 and extend outwardly, and the length thereof in the vertical direction can be less than the length of the clamping groove in the vertical direction. Further, the outer side of the second clamping part can be formed with a number of groove parts corresponding to the number of the first clamping parts, and the first clamping part as a strip-shaped part is configured to be fitted with the groove parts, thereby being accommodated in the groove parts. Based on the aforementioned features, the assembly mode of the first clamping part, the first limiting part, the second limiting part and the second clamping part will be described below.

[0106] In the embodiment, the second limiting part can be formed separately from the first clamping part, and therefore, the plurality of first clamping parts can be first inserted into the plurality of corresponding groove parts, and then the second limiting part of each corresponding first clamping part is installed at the lower end of the first clamping part, and is detachably installed by using a screw. Therefore, since the second clamping part is limited in the clamping groove defined by the first clamping part, the first limiting part and the second limiting part in the vertical direction, the second clamping part can make limited movement in the clamping groove in the vertical direction, which is also the movement form of the first accommodating member 130 and the second accommodating member 140. Again, due to the cooperation of the first clamping part and the groove part, the rotational movement of the first clamping part relative to the second clamping part is prevented, i.e. the first accommodating member 130 and the second accommodating member 140 can be synchronously rotated.

[0107] Further, continuing to refer to Figure 1 , the lower end of the second accommodating member 140 can further be provided with a drilling assembly 150, which can include a fixed part and a drill bit part (i.e. a lower drill bit 152), the fixed part can be connected with the lower end of the second accommodating member 140, and the drill bit part can be provided at the lower end of the fixed part. The fixed part and the drill bit part can jointly define a downward opening (i.e. a drilling accommodating part 151), which can be formed with the hole being drilled by the percussive drilling tool 100 as a drilling cavity 410, just as Figure 1As shown, the interior of the second accommodating member 140 is actually formed as an annular space, whereby the aforementioned inner drill rod 111 penetrating the first accommodating member 130 can further communicate with the drilling cavity 410 via the passage in the second accommodating member 140, i.e. the second accommodating member 140 is sleeved on the outer side of the inner drill rod 111.

[0108] In embodiments, the percussion drilling tool 100 further comprises a flow guide member 121, which can be sleeved on the outer side of the first accommodating member 130 and the second accommodating member 140, the upper end of the flow guide member 121 can be connected with the outer drill rod 113, and the lower end of the flow guide member 121 can be connected with the part of the aforementioned drilling assembly 150, whereby the inner side of the flow guide member 121, the outer side of the first accommodating member 130, the outer side of the second accommodating member 140 and the outer side of the fixed part jointly define a second conveying gap 122, which can communicate with the second conveying gap 122 via the first communication hole (i.e. the communication 160) opened at the lower end of the outer drill rod 113, and the second conveying gap 122 can be connected with the drilling cavity 410 via the second communication hole (i.e. the communication 160) opened at the lower end of the fixed part. In addition, the outer side of the flow guide member 121 can also be formed as a circular truncated cone shape, thereby facilitating the flow of soil or fluid above the flow guide member 121 to the outer side thereof, thereby facilitating the movement of the percussion drilling tool 100. Further, the outer side of the flow guide member 121 can be provided with an upper drill bit 153 in a shape matching the outer side thereof, which can further solve the problem of the difficulty of upward movement of the percussion drilling tool 100 due to the accumulation of soil above it.

[0109] On this basis, the first movement device can further comprise a central rotating member 131, a first rotating assembly 132 and a second rotating assembly 133. As an advantageous embodiment, the first rotating assembly 132 and the second rotating assembly 133 can be jointly formed as a hydraulic pump, for example, a plunger pump, which will be described in detail below. In embodiments, the central rotating member 131 can be formed as an external gear member, which can be sleeved on the outer side of the part of the inner drill rod 111 inside the first accommodating part and coaxial with the inner drill rod 111. Correspondingly, the first rotating assembly 132 can comprise a planetary gear member, for example, a planetary gear, and a rotating shaft coaxially connected with the planetary gear, and the second rotating assembly 133 can be formed as a pump body of a hydraulic pump, for example, a plunger pump, and the planetary gear can be meshed with the aforementioned external gear member.

[0110] In embodiments, still referring to Figure 1, the pump body of the plunger pump can be connected with the inner side of the first containing member 130, for example, the inner side of the first containing member extends inwardly to form a mounting plate, and the pump body of the plunger pump can be fixed on the mounting plate, in order to further ensure the stability of the cooperation between the planetary gear and the external gear member, the mounting plate can be formed as an annular plate, that is, the middle part of the mounting plate is formed with a hole portion for the inner drill rod 111 to penetrate, and a bearing can be defined between the inner edge of the hole portion and the outer side of the inner drill rod 111. Such a setting is particularly advantageous for ensuring that the mounting plate still has sufficient rigidity in the case of multiple plunger pumps, and of course, as mentioned above, the stability of the cooperation between the planetary gear and the external gear member is improved due to the participation of the bearing.

[0111] Thus, with the above setting, it is self-evident that the external gear member can rotate around its own axis (i.e. the first rotation axis) when the inner drill rod 111 rotates, and the pump body of the plunger pump can rotate around the first rotation axis as a whole by driving the first containing member 130 connected with the outer drill rod 113 when the outer drill rod 113 rotates, so that when the inner drill rod 111 and the outer drill rod 113 rotate in opposite directions, one of the inner drill rod 111 and the outer drill rod 113 rotates, and both the inner drill rod 111 and the outer drill rod 113 rotate in the same direction at different speeds, the relative rotation between the swivel shaft and the pump body of the plunger pump occurs, that is, the swivel shaft can be regarded as rotating around its own axis (i.e. the second rotation axis) relative to the plunger pump, so that the oil suction and oil discharge processes of the plunger pump are realized, and the mechanical energy transmitted by the inner drill rod 111 and the outer drill rod 113 is converted into hydraulic energy.

[0112] In an embodiment, the number of plunger pumps can be multiple, and the multiple plunger pumps are preferably arranged in a manner of equally dividing the circumference when viewed along the extension direction of the first rotation axis, so as to ensure that the stress condition on the whole percussion drill tool 100 is relatively balanced. In addition, the interior of the first containing member 130 can also be provided with a brake device 162 corresponding to the swivel shaft of each plunger pump. One end of the brake device 162 can be connected with the interior of the first containing member 130, see Figure 3 and Figure 4, both of which show examples of the brake device 162, which can be formed as a hydraulic brake caliper as an option, the control oil of the hydraulic brake caliper can be supplied by the aforementioned plunger pump to provide the pressure of the hydraulic brake caliper to the pressing shaft member. In an embodiment, the inside of the first containing member 130 can also be provided with a hydraulic medium storage device, such as an oil tank, which can store hydraulic oil as a hydraulic medium inside, the input end of the plunger pump can be communicated with the oil tank via a first pipeline (not shown in the figure) for sucking hydraulic oil from the oil tank, and the output end of the plunger pump can be communicated with a second pipeline (not shown in the figure) which can input the pressure oil into the second containing member 140, and the specific path of the pressure oil will be described later.

[0113] In an embodiment, the pressure oil output by the plurality of plunger pumps can be respectively input into the distribution mechanism 134 via the respective second pipelines, and the distribution mechanism 134 can be formed as a substantially oil storage member, which can input the pressure oil into the second containing member 140 by sequentially penetrating the third pipeline (not shown in the figure) through the lower end of the first containing member 130 and the upper end of the second containing member 140, and the third pipeline can be formed in sealing connection with both the first containing member 130 and the second containing member 140, i.e. the outer side of the third pipeline is sealingly connected with the hole portion through which the third pipeline penetrates, for example, a flexible sealing gasket is provided between the outer side of the third pipeline and the hole portion through which the third pipeline penetrates. The number of third pipelines can be determined according to the number of hydraulic motors 141, for example, the number of third pipelines can be the same as the number of hydraulic motors 141. Therefore, due to the provision of the distribution mechanism 134, the difference in rotational speed of the hydraulic motors 141 caused by the difference in operating state of the different plunger pumps is avoided, that is, because the distribution mechanism 134 contains, buffers and redistributes the pressure oil, all the hydraulic motors can operate synchronously.

[0114] The second movement device can also include a conversion device, which can be provided in the second containing member 140 and communicated with the aforementioned distribution mechanism 134. In one embodiment, the conversion device can include a first conversion mechanism and a second conversion mechanism, the first conversion mechanism can be formed as a hydraulic motor 141, which can be driven by the pressure oil, and the hydraulic oil inside the hydraulic motor 141 after work is done can be returned to the oil tank via the third pipeline (not shown in the figure). The second conversion mechanism can be formed as a vibration exciter 142, which can be driven to rotate and vibrate by the hydraulic motor 141, so that when the vibration exciter 142 is connected with the second containing member 140, the second containing member 140 can reciprocate in the vertical direction, thereby enabling the drilling assembly 150 to cut the hole bottom and hole wall of the hole to be drilled. In addition, in another embodiment, the conversion device can be directly formed as a hydraulic vibration exciter 142, which is directly driven to vibrate by the hydraulic oil in the second pipeline.

[0115] Similarly, the first rotating assembly 132 and the second rotating assembly 133 can also be jointly formed as a generator, the first rotating assembly 132 can still include the planetary gear member and the planetary gear member, and can further include the rotor of the generator, and the second rotating assembly 133 can be formed as the body of the generator. In this case, the conversion device can include the motor and the exciter 142 (the specific structure of the exciter 142 will be described below), or the conversion device is directly formed as the electric exciter 142. In addition, in the case of the above-mentioned generator, the drilling assembly 150 and the conversion device can also be replaced by a device that integrates energy conversion and drilling, such as an ultrasonic generator or a laser cutter, so that ultrasonic drilling or laser cutting can be used for certain underwater application scenarios.

[0116] As shown in Figure 7 and Figure 8 , Figure 7 shows a top view of the exciter 142, which includes an inner drill rod passage 145 adapted to the inner space of the second accommodating member 140, so that the cylindrical wall part formed in the passage of the second accommodating member 140 is accommodated by the inner drill rod passage 145. In combination with Figure 8 , Figure 8 shows a schematic diagram of the arrangement of the excitation gear set 148 of the exciter 142, in the embodiment, the gears are schematically given in a circular shape, and two tangent circles are considered to be engaged. Continue to refer to Figure 8 , the two largest gears at the top can be the output gears of the hydraulic motor 141 described above, and all the large gears below are formed as gears for transmitting mechanical energy arranged in the exciter 142. In combination with Figure 7 , between every two small gears facing each other in the vertical direction of Figure 7 , there is an excitation shaft 144 coaxial with the two small gears, which can rotate synchronously with the two small gears, and two eccentric members 143 can be arranged on the excitation shaft 144, which have a missing part that allows the eccentric member 143 to avoid the flow guide passage 146 described below and the inner drill rod passage 145 described above. On this basis, the excitation shaft 144 is arranged with two groups (the eccentric members 143 arranged corresponding to the two groups of excitation shafts 144 are also divided into two groups), and they are symmetrical to each other. Refer to Figure 8 , in the arrangement shown, the rotation directions of the two groups of small gears corresponding to the two groups of excitation shafts 144 are opposite, thereby generating excitation force in the vertical direction, and the centrifugal force of the two groups of eccentric members 143 in the horizontal direction is cancelled out. In this arrangement of the exciter 142, it can cooperate with the structure of the second accommodating member 140 and meet the arrangement requirements of the inner drill rod 111, and the arrangement of multiple layers of eccentric members 143 can also ensure that the excitation force is large enough to meet the drilling requirements.

[0117] Still referring to Figure 7 , the exciter 142 is further provided with two flow guide channels 146 and two flow guide gaps 147 on both sides of the exciter 142. The flow guide channels 146 and the flow guide gaps 147 can both allow fluid to pass, so they can be selected to communicate with the second conveying gap 122 according to actual conditions to increase the applicability of the exciter 142.

[0118] On the basis of the above-described features, the following will describe the circulation mode when drilling with the fluid. As Figure 12 shown, as mentioned in the above description, the first conveying gap 114, the second conveying gap 122, the drilling cavity 410 and the inner hollow portion 112 are sequentially communicated, so that between the mud pit 420 and the hole bottom of the hole to be drilled 400, three circulation channels are formed, that is, the first circulation channel is composed of the mud pit 420, the space between the outer drill rod 113 and the hole wall of the hole to be drilled 400, the space between the shock drill and the hole wall of the hole to be drilled 400, and the drilling cavity 410; the second circulation channel is composed of the mud pit 420, the mud treatment machine 330, the high-pressure mud pump, the second air-water swivel nozzle to be described below, the third conveying gap 232, the first conveying gap 114, the second conveying gap 122 and the drilling cavity 410; and the third circulation channel is composed of the mud pit 420, the mud pump, the first air-water swivel to be described below, the third hollow portion to be described below, the inner hollow portion 112 to be described below, and the drilling cavity 410.

[0119] In the embodiments, all of the above circulation modes can be applicable to mud circulation. For mud circulation, as Figure 2As shown, a submersible drilling slurry pump 161 can be installed in the inner middle part of the inner drill rod 111, the pump body of the submersible drilling slurry pump is installed in the lower part of the first movement device, and forms a rotatable sealed connection with the part of the inner drill rod 111 above it and the part of the inner drill rod below it, the submersible drilling slurry pump can be driven through the aforementioned distribution mechanism 134, and can be connected with the first containing member, so as to be supported, so as to cooperate with the mud circulation, and for air circulation (also known as pneumatic circulation), the drilling assembly 150 can be replaced with a reverse circulation down-the-hole hammer and a down-the-hole hammer, air enters the first conveying gap 114 from the second air and water swivel 220, drives the reverse circulation down-the-hole hammer to work, carries the drilling slurry back to the fluid source from the inner cavity 112 of the inner drill rod 111, which is called air reverse circulation down-the-hole drilling. Or without replacing the drilling assembly 150, a gas-liquid mixer is installed at a suitable depth of the to-be-drilled hole 400, air enters the first conveying gap 114 from the second air and water swivel 220, enters the inner cavity 112 of the inner drill rod 111 from the gas-liquid mixer, mixes with the mud in the inner cavity 112, carries the drilling slurry back from the inner cavity 112, which is called gas lift reverse circulation. However, the main purpose of these circulations is to remove the drilling slurry generated in the to-be-drilled hole 400 during drilling from the to-be-drilled hole 400.

[0120] Therefore, it can be seen that the percussion drilling tool 100 includes drilling actions performed by the first movement device and the second movement device together to perform drilling, and also includes fluid circulation to perform drilling, and the two drilling processes can be combined. Taking the first rotary assembly 132 and the second rotary assembly 133 together to form a plunger pump as an example, without fluid circulation, for example, when the inner drill rod 111 and the outer drill rod 113 rotate in opposite directions, the plurality of planetary gears rotate around the second rotation axis while meshing with the outer gear member around the first rotation axis, so that the plunger pump starts to work, and since the outer drill rod 113 is connected with the first containing member 130, the rotation of the outer drill rod 113 will simultaneously drive the first containing member 130 to rotate, so that the first containing member 130 and the second containing member 140 rotate synchronously around the first rotation axis, so that the drilling assembly 150 can perform rotary drilling on the to-be-drilled hole 400. At the same time, the aforementioned plunger pump drives the second movement device with pressure oil, so that the second movement device reciprocates along the vertical direction, which can be understood as percussion action, that is, in this case, the percussion drilling tool 100 performs both rotary action and percussion action.

[0121] Therefore, in general, as long as the outer drill rod 113 rotates, the percussion drill 100 performs a rotating action, and as long as the rotary shaft rotates around the second rotary shaft, the percussion drill 100 can perform a percussion action. On this basis, drilling can also be performed in cooperation with the above fluid circulation mode. It can be seen from the percussion drill that the multifunctional drilling machine 300 has extremely high applicability, and by transmitting mechanical energy through the inner drill rod 111 and the outer drill rod 113, converting the mechanical energy into other forms of energy by the first rotary assembly 132 and the second rotary assembly 133, and then driving the second movement device by the other forms of energy, the limitation of energy transmission of the previous drill is overcome, thereby greatly enriching the drilling function of the multifunctional drilling machine 300 and improving the drilling efficiency. The working mode of the percussion drill 100 will be described below according to different working conditions of the double drill rod and different fluid circulation conditions. It should be noted that the working modes described below are not all working modes.

[0181] In this process, other mud pumps are closed, and other valves are closed.

[0182] This way is the unique drilling way of the application.

[0183] 13, pneumatic reverse circulation drilling

[0184] Install pneumatic reverse circulation down-the-hole hammer and down-the-hole hammer at the bottom of the double drill rod, and rotate the double drill rod in the same direction and at the same number of revolutions.

[0185] Start the air compressor, high pressure air from the air compressor, in turn into the second gas water faucet 220, the third delivery gap 232, the first delivery gap 114, the second delivery gap 122, drive the pneumatic reverse circulation impactor to drive the down-the-hole hammer to impact the hole bottom, carry the drill cuttings in turn via the inner hollow part 112, the first gas water faucet 210 to return to the ground.

[0186] In this process, other mud pumps are closed, and other valves are closed.

[0187] This is the drilling mode in the prior art. However, it is not limited thereto. The central rotating member 131 can be formed as an internal gear member and arranged inside the first accommodating member 130, the second rotating member can be connected with the internal drill rod 111, and the planetary gear member can be in internal meshing with the internal gear member. Alternatively, the aforementioned arrangement in this paragraph can be combined with the aforementioned arrangement and arranged inside the first accommodating member 130, i.e. in a layered manner in the vertical direction, for example, inside the first accommodating member 130, the upper layer is arranged with the externally meshing central rotating member 131 and the planetary gear member, and the lower layer is arranged with the internally meshing central rotating member 131 and the planetary gear member, and of course it is not limited to two layers. In addition, the central rotating member 131 is not arranged, and only one set of the first rotating assembly 132 and the second rotating assembly 133 is arranged, the axis of the rotating shaft of the first rotating assembly 132 is coaxial with the first rotating axis and connected with the internal drill rod 111, and the second rotating assembly 133 is connected with the first accommodating member 130, in which case the internal hollow portion 112 can pass through the first accommodating member 130 through bypass pipes avoiding the first rotating assembly 132 and the second rotating assembly 133, and the bypass pipes can all communicate with the main pipe, and the main pipe passes through the passage of the aforementioned second accommodating member 140.

[0188] In addition, as shown in Figure 3 and Figure 4 , Figure 3 and Figure 4 A second embodiment of the percussion drilling tool 100 is given. In this example, only a single drill rod 111a is arranged, and the remaining similar structures are not described again, and the working principle of this percussion drilling tool 100 will be described below.

[0189] As shown in Figure 3 , Figure 3In the second embodiment of the percussion drilling tool 100, the drilling assembly 150 is a rotary drilling assembly 150. When the single drill rod 111a rotates, the central rotary member 131 (the outer gear member) rotates to drive the planetary gear member to rotate, and at this time, the rotary shaft rotates synchronously. The energy conversion device formed by the first rotary assembly 132 and the second rotary assembly 133, for example, a plunger pump, starts to work, and then drives the exciter 142 in the second movement device to make the second movement device perform the percussion action in a similar manner as described above. In this process, the second rotary assembly 133 applies a force to the first containing member 130 to give the first containing member 130 a tendency to rotate in the same direction as the single drill rod 111a, but due to the friction of the hole bottom and the hole wall of the hole to be drilled 400 on the drilling tool, the first containing member 130 will maintain a static state. Once the friction of the hole bottom and the hole wall is not enough to maintain the static state of the first containing member 130 through the percussion action of the second movement device, the first containing member 130 will rotate in the same direction as the single drill rod 111a, and the second containing member 140 and the drilling assembly 150 will also rotate, realizing further drilling. It can be predicted that when the first containing member 130 rotates, the plunger pump as a whole rotates around the axis of the single drill rod 111a, which will reduce the rotation speed of the rotary shaft and further reduce the displacement output by the plunger pump. Therefore, after the first containing member 130 rotates, the amplitude of the percussion action will decrease, which will increase the friction of the hole bottom and the hole wall on the first containing member 130, and then return to the static state described above. The alternating of such reciprocating working states realizes the entire drilling process. In addition, the brake device 162 described above can particularly adjust the balance between rotation and percussion in the second embodiment of the percussion drilling tool 100.

[0190] Similarly, Figure 4 In the second embodiment of the percussion drilling tool 100, the drilling assembly 150 is a rotary drilling assembly 150. When the single drill rod 111a rotates, the central rotary member 131 (the outer gear member) rotates to drive the planetary gear member to rotate, and at this time, the rotary shaft rotates synchronously. The energy conversion device formed by the first rotary assembly 132 and the second rotary assembly 133, for example, a plunger pump, starts to work, and then drives the exciter 142 in the second movement device to make the second movement device perform the percussion action in a similar manner as described above. In this process, the second rotary assembly 133 applies a force to the first containing member 130 to give the first containing member 130 a tendency to rotate in the same direction as the single drill rod 111a, but due to the friction of the hole bottom and the hole wall of the hole to be drilled 400 on the drilling tool, the first containing member 130 will maintain a static state. Once the friction of the hole bottom and the hole wall is not enough to maintain the static state of the first containing member 130 through the percussion action of the second movement device, the first containing member 130 will rotate in the same direction as the single drill rod 111a, and the second containing member 140 and the drilling assembly 150 will also rotate, realizing further drilling. It can be predicted that when the first containing member 130 rotates, the plunger pump as a whole rotates around the axis of the single drill rod 111a, which will reduce the rotation speed of the rotary shaft and further reduce the displacement output by the plunger pump. Therefore, after the first containing member 130 rotates, the amplitude of the percussion action will decrease, which will increase the friction of the hole bottom and the hole wall on the first containing member 130, and then return to the static state described above. The alternating of such reciprocating working states realizes the entire drilling process. In addition, the brake device 162 described above can particularly adjust the balance between rotation and percussion in the second embodiment of the percussion drilling tool 100. Figure 3

[0191] It should be noted that the second embodiment of the percussion drilling tool 100 is not limited to the above-described drilling assembly 150, and can still be applied to other drilling assemblies 150.

[0192] The present embodiment also provides a multifunctional drilling rig 300, which comprises the double drill rod percussion drilling tool 100 as described above, and further comprises a driving device 200 for driving the double drill rod.

[0193] As Figure 5 to Figure 6 shown in the embodiment, the driving device 200 can comprise:

[0194] ​The first driving joint 230 can be connected with the upper end of the inner drill rod 111, and the first driving joint 230 can be formed with a third hollow portion for conveying fluid, which communicates with the inner hollow portion 112.

[0195] The second driving joint 231 is connected with the upper end of the outer drill rod 113 away from the drilling tool, and the second driving joint 231 can be formed with a fourth hollow portion for conveying fluid, and the second driving joint 231 can be sleeved on the outer side of the first driving joint 230, and the third conveying gap 232 is defined by the outer side of the first driving joint 230 and the inner side of the second driving joint 231.

[0196] The first driving mechanism 213 can be arranged on the first mounting member 215 and used for driving the first driving joint 230 to rotate, and the second driving mechanism 223 can be arranged on the second mounting member 225 and used for driving the second driving joint 231 to rotate.

[0197] The first rotary support 214 includes an alpha ring and a beta ring capable of rotating relative to each other, the alpha ring can be arranged on the first mounting member 215, and the beta ring can be connected with the first driving joint 230, and the second rotary support 224 includes a gamma ring and a delta ring capable of rotating relative to each other, the gamma ring can be arranged on the second mounting member 225, and the delta ring can be connected with the second driving joint 231.

[0198] In the embodiment, the first driving mechanism 213 can include a plurality of driving assemblies, a reducer corresponding to each driving assembly, and a gear corresponding to the output end of each prime mover and matched with the rotary support. The driving assembly here can be preferably a hydraulic motor and an electric motor, or can be a driving assembly driven by other energy sources, which is not specifically limited here, and of course can be a combination of a plurality of different driving assemblies to increase the applicability of the first driving mechanism 213. Similarly, the second driving mechanism 223 is also the same. Further, the first driving mechanism 213 is matched with the beta ring to drive the beta ring and the first driving joint 230 to rotate, and the second driving mechanism 223 is matched with the delta ring to drive the delta ring and the second driving joint 231 to rotate, so that the inner drill rod 111 and the outer drill rod 113 are driven.

[0199] In addition, the multifunctional drilling machine 300 can further include a first air and water swivel 210, which can also be arranged on the first mounting member 215, and the first driving joint 230 is rotatably and sealingly connected with the first air and water swivel 210. The multifunctional drilling machine 300 can further include a second air and water swivel 220, which can also be arranged on the second mounting member 225, and the first driving joint 230 and the second driving joint 231 are respectively rotatably connected with the second air and water swivel 220, and the second air and water swivel 220 communicates with the third conveying gap 232. Specifically, especially with reference toFigure 5 The first air faucet 210 has a first air faucet mud port 211 and a first air faucet air hole 212 respectively connected to the third hollow part. The second air faucet 220 has a second air faucet water port 221 and a second air faucet air hole 222 respectively connected to the third conveying gap 232. Thus, the above-mentioned fluid is circulated through the two air faucets and an external air pump or mud pump.

[0200] In this embodiment, for ease of transport and assembly, the inner drill rod 111 and the outer drill rod 113 can be separated into multiple segments. Each segment of the inner drill rod 111 and each segment of the outer drill rod 113 can form an assembly, including an upper connector and a lower connector. In use, the lower connector of one assembly is connected to the upper connector of another assembly. The specific structure of the two connectors of the assembly will be described in detail in the following description.

[0201] like Figure 10 As shown, the lower end of the inner drill rod 111 is provided with a first connecting member 240 (which is generally cylindrical in shape; the shapes of the connecting members described below are also generally cylindrical). The outer side of the first connecting member 240 may form a first abutment portion 243. The first abutment portion 243 may be formed in the shape of a rib and multiple such portions may be provided, thereby ensuring that fluid can pass between the first connecting member 240 and the second connecting member 241. Therefore, in fact, the space between the first connecting member 240 and the second connecting member 241 is part of the first conveying gap 114. The lower end of the outer drill rod 113 may be provided with a second connecting member 241. The inner side of the second connecting member 241 may form a first mounting recess. A slewing bearing member, such as a bearing, may be installed in the first mounting recess, and a sealing ring for sealing the bearing may be further installed therein, so that the first abutment portion 243 abuts against and moves with the inner ring of the bearing, and the second connecting member 241 moves with the outer ring of the bearing. The outer side of the second connecting member 241 may also be provided with a third connecting member 242, and the lower end of the inner side of the third connecting member 242 may be formed with an internal thread.

[0202] like Figure 9 As shown, the upper end of the inner drill rod 111 may be provided with a fourth connecting member 244, and the outer side of the fourth connecting member 244 forms a second abutment portion 246 (the structure of the second abutment portion 246 may be the same as that of the first abutment portion 243, and the number may be multiple). The upper end of the outer drill rod 113 may be provided with a fifth connecting member 245, and the inner side of the fifth connecting member 245 may form a second mounting recess. A rotary support member, such as a bearing, is installed in the second mounting recess. The way the bearing, the second mounting recess, and the second abutment portion 246 are matched is similar to the above-mentioned way, and will not be described again here.

[0203] Further, the outer side of the first connecting member 240 can be formed with a first outer spline, the inner side of the fourth connecting member 244 can be formed with a first inner spline, similarly, the outer side of the second connecting member 241 can be formed with a second outer spline, and the inner side of the fifth connecting member 245 can be formed with a second inner spline. Thus, in the assembled state of the assembly, referring to Figure 11 , the first connecting member 240 can be inserted into the inner side of the fourth connecting member 244, and the first outer spline is engaged with the first inner spline, the second connecting member 241 is inserted between the fourth connecting member 244 and the fifth connecting member 245, and the second outer spline is engaged with the second inner spline, and the fifth connecting member 245 is confined between the second connecting member 241 and the third connecting member 242. The outer side of the fifth connecting member 245 can be formed with an outer thread for mating with the inner thread of the third connecting member 242 as mentioned above. Still referring to Figure 9 , the fourth connecting member 244 and the fifth connecting member 245 are both formed with a step, in the above assembled state, the first connecting member 240 can abut against the step of the inner side of the fourth connecting member 244, and a sealing ring is arranged between the step and the end of the first connecting member 240; the second connecting member 241 can abut against the step of the inner side of the fifth connecting member 245, and a sealing ring is arranged between the step and the fifth connecting member 245. In this way, the inner drill rod 111 and the outer drill rod 113 can not only rotate relative to each other, but also ensure that the fluid can flow through the first conveying gap 114 defined by the two drill rods. Thus, referring to Figure 5 , the lower ends of the two driving joints of the driving device 200 actually form the lower joint of the above-mentioned assembly, so as to be connected with the upper joint of one of the above-mentioned assemblies.

[0204] The multifunctional drilling rig provided by the embodiment can further include the following structures, as shown in Figure 12 , that is, the multifunctional drilling rig can further include a drilling rig engine 310, an airborne air compressor 320, a lifting system 380, and an external air compressor 390, and the mud treatment machine 330, the mud mixing tank 340, the first mud pump 350, the second mud pump 360, and the third mud pump 370 mentioned above. Among them, the drilling rig engine 310, the airborne air compressor 320, the mud mixing tank 340, the first mud pump 350, the second mud pump 360, and the third mud pump 370 can be transported by the transport vehicle. In the embodiment, the lifting system 380 can include a mast arranged in the vertical direction on the transport vehicle, and a lifting mechanism arranged on the mast, for example, a lifting mechanism driven by a hydraulic cylinder, so as to lift or lower the drilling rig 100.

[0205] The above merely describes the preferred embodiments of the present application, and is not intended to limit the protection scope of the present application, and any equivalent structure transformation made according to the innovative concept of the present application, or direct / indirect application in other related technical fields, is included in the protection scope of the present application.
