However, this modular design presents several technical challenges: it still requires a significant number of personnel for complete disassembly, relocation, and assembly, leaving room for improvement in personnel allocation, per-well personnel consumption, and work efficiency.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] The directional nouns involved in the embodiments of this application, such as "upper", "lower", "side", etc., are generally expressed in the form of Figure 1 The relative relationships shown in the figure are used as a reference, and these directional terms are used only to more clearly describe the relationship between structures, not to describe absolute directions. When the product is placed in different postures, the direction may change, for example, "up" and "down" may be interchangeable.

[0034] Unless otherwise defined, all technical terms used in the examples of this application have the same meanings as those commonly understood by those skilled in the art. Some technical terms that appear in the examples of this application are explained below.

[0035] In order to make the technical solutions and advantages of the present application clearer, the implementation methods of the present application will be described in further detail below with reference to the accompanying drawings.

[0036] like Figure 1 As shown, an embodiment of the present application provides a split mountain drilling rig, including a first module 1, a second module 2 and a remote gas transmission pipe 3, and the first module 1 and the second module 2 are arranged in a split manner.

[0037] The first module 1 includes a hydraulic submodule 13 and a power head assembly 16 connected to each other. The hydraulic submodule 13 is used to deliver hydraulic oil to the power head assembly 16, and the power head assembly 16 is used to drive the drill rod.

[0038] Exemplarily, the hydraulic submodule 13 includes a hydraulic power device such as a hydraulic pump, which can provide hydraulic power to the power head assembly 16, thereby enabling the power head assembly 16 to drive the drill rod to drill the mountain.

[0039] The second module 2 includes an air compressor submodule 21 . The air compressor submodule 21 is connected to the first module 1 via a remote air supply pipe 3 . The air compressor submodule 21 is used to remotely supply compressed air to the power head assembly 16 .

[0040] Specifically, one end of the remote air supply pipe 3 is connected to the compressed air output end of the air compressor sub-module 21, and the other end is connected to the compressed air input end of the first module 1, so that the second module 2 can remotely supply compressed air to the first module 1, providing the power head assembly 16 with pneumatic power to drive the drill rod to rotate, cut and crush rocks.

[0041] For example, when drilling operations are carried out in mountainous areas, the second module 2 is placed at the foot of the mountain, and compressed air can be remotely delivered to the first module 1 on the mountain, which greatly reduces the relocation workload, thereby reducing the manpower allocation of drilling operations, reducing single-well consumption and improving drilling efficiency.

[0042] Specifically, the length of the long-distance gas transmission pipe 3 can be set according to actual needs and can be formed by connecting multiple gas transmission pipe sections. In actual application, the length of the long-distance gas transmission pipe 3 can reach 2 km, or even more than 2 km.

[0043] The split mountain drilling rig provided in the embodiment of the present application has a split arrangement of the first module 1 and the second module 2. Therefore, when performing drilling operations, after the first module 1 is transported to the drilling operation point, the second module 2 does not need to be transported to the same location as the first module 1. The drilling operation can be carried out smoothly by remotely supplying compressed air to the first module 1 using the second module 2, which greatly reduces the relocation distance of the second module 2, helps to reduce the personnel allocation of the drilling operation, reduce the consumption of a single well and improve the drilling work efficiency.

[0044] In a further embodiment, the first module 1 also includes a rack sub-module 11 and an operating valve sub-module 12. The operating valve sub-module 12 and the hydraulic sub-module 13 are both detachably connected to the rack sub-module 11. The operating valve sub-module 12 is respectively connected to the hydraulic sub-module 13 and the power head assembly 16, and the operating valve sub-module 12 is connected to the air compressor sub-module 21 through the remote air supply pipe 3. The operating valve sub-module 12 is used to adjust the pressure of the fluid leading to the power head assembly 16.

[0045] By detachably connecting the operating valve submodule 12 and the hydraulic submodule 13 to the frame submodule 11, the operating valve submodule 12 and the hydraulic submodule 13 can be quickly and easily disassembled and assembled, thereby improving the disassembly and assembly efficiency of the split-type mountain drilling rig.

[0046] Exemplarily, the hydraulic sub-module 13 and the operating valve sub-module 12 are connected via a hydraulic pipeline; the operating valve sub-module 12 and the power head assembly 16 are connected via a hydraulic pipeline and an air pipeline; the end of the remote air pipeline 3 facing away from the air compressor sub-module 21 is connected to the compressed air input end of the operating valve sub-module 12, so that the air compressor sub-module 21 delivers compressed air to the operating valve sub-module 12 via the remote air pipeline 3.

[0047] Specifically, the operating valve submodule 12 can regulate the pressure of the hydraulic oil and compressed air leading to the power head assembly 16, such as adjusting the pressure size, direction, on-off, etc., to meet various production needs.

[0048] In a further embodiment, the first module 1 further includes a first power submodule 14 , which is detachably connected to the frame submodule 11 , and is drivingly connected to the hydraulic submodule 13 and used to provide power to the hydraulic submodule 13 .

[0049] For example, Figure 2 As shown, the operating valve submodule 12 includes an operating valve submodule frame 121 and an operating valve assembly 122 installed inside the operating valve submodule frame 121. The hydraulic submodule 13 includes a hydraulic submodule frame 131 and a hydraulic assembly 132 installed inside the hydraulic submodule frame 131. The first power submodule 14 includes a first power submodule frame 141 and a first power machine 142 installed inside the first power submodule frame 141. The first power submodule frame 141 is detachably connected to the hydraulic submodule frame 131. The power output end of the first power machine 142 is connected to the power input end of the hydraulic assembly 132 by transmission, for example, using a belt drive structure. Optionally, the first power machine 142 is a diesel engine, which can better meet performance requirements.

[0050] Through the above configuration, the operating valve submodule frame 121 can protect the operating valve assembly 122 , the first power submodule frame 141 can protect the first power machine 142 , and the hydraulic submodule frame 131 can protect the hydraulic assembly 132 .

[0051] Alternatively, as Figure 1 As shown, the first power submodule 14 is stacked on top of the hydraulic submodule 13 , which helps to reduce the size and weight of the frame submodule 11 .

[0052] The second module 2 further includes a second power submodule 22 . The second power submodule 22 is detachably connected to the air compressor submodule 21 . The second power submodule 22 is used to provide power for the air compressor submodule 21 .

[0053] For example, Figure 3 As shown, the air compressor submodule 21 includes an air compressor submodule frame 211 and an air compressor assembly 212 installed inside the air compressor submodule frame 211. The second power submodule 22 includes a second power submodule frame 221 and a second power machine 222 installed inside the second power submodule frame 221. The air compressor submodule frame 211 and the second power submodule frame 221 are detachably fixedly connected. The power output end of the second power machine 222 is connected to the power input end of the air compressor assembly 212 by transmission, for example, a belt drive structure can be used for transmission connection. Optionally, the second power machine 222 is a diesel engine, which can better meet performance requirements.

[0054] In the split-type mountain drilling rig provided in the embodiment of the present application, the operating valve sub-module 12, the hydraulic sub-module 13 and the first power sub-module 14 constitute a hydraulic station for delivering hydraulic oil to the power head assembly 16, and the air compressor sub-module 21, the second power sub-module 22 and the operating valve sub-module 12 constitute a compressed air station for delivering hydraulic air to the power head assembly 16. The implementation principles and components of the hydraulic station and the compressed air station in the present application can refer to the existing air drilling rig settings, and the components of the operating valve assembly 122, the hydraulic assembly 132 and the air compressor assembly 212 and the connection method between the components can refer to the existing air drilling rig settings, for example, the FDZ-30 and FDZ-50 drilling rig settings of Sichuan Jisset Technology Co., Ltd. can be referred to, which will not be repeated here.

[0055] In a further embodiment, the split-type mountain drilling rig further includes a communication unit that is communicatively connected to the second power submodule 22 , and the communication unit is installed in the first module 1 , and is used to remotely control the working state of the second power submodule 22 .

[0056] In this embodiment, the second power submodule 22 is a remote-controlled power submodule, and the communication unit and the second power submodule 22 can be connected to each other via a wired or wireless communication method.

[0057] By installing the communication unit on the first module 1, the operator at the drilling operation point can remotely control the start and stop of the second power submodule 22 directly through the communication unit on the first module 1, thereby reducing the number of operators located at the second module 2 and the number of drilling operation personnel, which is conducive to reducing personnel costs and improving the safety of drilling operations.

[0058] Optionally, the control end of the second power machine 222 is used as a communication unit, the communication unit is installed on the first module 1, and the communication unit and the second power machine 222 are connected by a cable to achieve wired communication connection.

[0059] Optionally, a remote control component is added to the existing power sub-module as the second power sub-module 22, and remote control of the second power sub-module 22 is achieved through the communication unit; or, a power sub-module with remote control function sold on the market is directly selected as the second power sub-module 22, for example, a 60kw remote control version engine model DV210 of Anhui Hangrui Aviation Power Equipment Co., Ltd. is selected as the second power machine 222 of the second power sub-module 22.

[0060] In one embodiment, the split-type mountain drilling rig further includes a remote controller 10 communicatively connected to the second power submodule 22 , and the remote controller 10 is used to remotely control the working state of the second power submodule 22 .

[0061] Specifically, the second power machine 222 has an electronic control unit 30 (Electronic Control Unit, referred to as ECU), the second power submodule 22 also includes a wireless communication unit 20 electrically connected to the electronic control unit 30, and the remote control 10 can be connected to the wireless communication unit 20 for communication. Figure 4 As shown, the remote controller 10 is used to send control signals for controlling the start, stop and operation of the second power machine 222. After receiving the control signals, the wireless communication unit 20 sends them to the electronic control unit 30. The electronic control unit 30 controls the start, stop and operation of the second power machine 222 according to the received control signals.

[0062] For example, a wireless communication unit 20 based on wireless communication protocols such as GRM, PWM, PPM, and S-BUS may be used.

[0063] In this embodiment, the mountain drilling rig in the prior art can be modified to fully utilize the power module of the existing mountain drilling rig, which helps to reduce costs.

[0064] In one embodiment, Figure 1 As shown, the first module 1 further includes a mast submodule 15 , which is detachably connected to the frame submodule 11 , and a power head assembly 16 is mounted on the mast submodule 15 .

[0065] By providing the mast submodule 15, an installation position is provided for the power head assembly 16; by providing the mast submodule 15 and the frame submodule 11 with a detachable connection, it helps to improve the disassembly and assembly efficiency of the split mountain drilling rig.

[0066] Specifically, if Figure 2As shown, the mast sub-module 15 includes a mast body 151 and a support rod 152. The first end of the mast body 151 and the first end of the support rod 152 are both detachably connected to the rack sub-module 11, and the second end of the mast body 151 is connected to the second end of the support rod 152, and the mast body 151 and the support rod 152 are inclined to each other.

[0067] like Figure 2 As shown, the first end of the mast body 151 and the first end of the support rod 152 are both lower ends, and the second end of the mast body 151 and the second end of the support rod 152 are both upper ends.

[0068] The lower end of the mast body 151 is detachably connected to the front of the rack submodule 11, specifically by threaded fasteners, snap-fit ​​connections, or the like. Because the first module 1 and the second module 2 are separate components, the second module 2 does not occupy the installation space of the rack submodule 11. Therefore, the lower end of the support rod 152 can be directly connected to the rear of the rack submodule 11. The length of the mast body 151 forms an angle less than 90° with the length of the support rod 152. The mast body 151, support rod 152, and rack submodule 11 form a stable triangular structure, enhancing the overall structural strength and stability of the first module 1.

[0069] In a further embodiment, the support rod 152 is a telescopic structure with adjustable length.

[0070] For example, the support rod 152 includes two coaxially arranged telescopic rods. The first telescopic rod is hollow and has an inner diameter larger than the outer diameter of the second telescopic rod. The second telescopic rod is inserted into the first telescopic rod and can move along its own length to achieve the length adjustment function of the support rod 152. It is understood that the first telescopic rod can be the telescopic rod located at the top or the telescopic rod located at the bottom.

[0071] By setting the support rod 152 as a telescopic structure with adjustable length, it is convenient to adjust the inclination angle between the mast body 151 and the ground before construction, so that the mast body 151 can fully adapt to the local terrain environment and ensure that the split mountain drilling rig works normally at the correct drilling angle.

[0072] In one embodiment, Figure 2 As shown, the mast submodule 15 further includes a lifting platform 153 and a lifting motor 154 .

[0073] The lifting platform 153 is slidably connected to the mast body 151 , the power head assembly 16 is installed on the lifting platform 153 , and the lifting motor 154 is transmission-connected to the lifting platform 153 . The lifting motor 154 is used to drive the lifting platform 153 to move along the length direction of the mast body 151 .

[0074] Illustratively, lift motor 154 is a hydraulic motor.

[0075] Exemplarily, the mast body 151 is provided with a guide rail, which extends along the length direction of the mast body 151 , and the lifting platform 153 can slide up and down along the length direction of the mast body 151 under the limitation of the guide rail.

[0076] Optionally, the mast submodule 15 further includes a lifting transmission mechanism, which is connected to the lifting platform 153 and the lifting motor 154 respectively. The lifting transmission mechanism is used to transmit the power of the lifting motor 154 to the lifting platform 153, so that the hydraulic motor drives the lifting platform 153 to move up and down.

[0077] Exemplarily, the lifting transmission mechanism is a chain lifting mechanism installed on the mast body 151. The lifting transmission mechanism includes two rotatable sprockets connected to the mast and chains mounted on the two sprockets. The lifting platform 153 is connected to the chain. The lifting motor 154 is used to drive a sprocket to rotate, which can drive the lifting platform 153 to move up and down, and then drive the power head assembly 16 to move up and down.

[0078] In one embodiment, Figure 2 As shown, the rack submodule 11 includes a support frame 111 and a plurality of support legs 112 connected to the bottom of the support frame 111 .

[0079] Multiple support legs 112 extend downward relative to the bottom of the support frame 111. The multiple support legs 112 are used to support the ground. The support frame 111 is used to support the operating valve sub-module 12, the hydraulic sub-module 13, the first power sub-module 14, and the mast sub-module 15.

[0080] In a specific implementation, connection points for detachably connecting the sub-modules can be provided on the support frame 111, and connection structures such as connection holes, connection pins, and connection studs can be provided at the connection points; the support legs 112 are all configured to have a length-adjustable structure with the lower end extending downward from the support frame 111.

[0081] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless expressly limited otherwise.
