Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a deep well tracked electric-driven drilling rig and its transportation method. Background Technology

[0002] Deep well tracked drilling rigs are mainly used for various deep-hole drilling operations, such as coalbed methane drilling, deep geothermal drilling, oil exploration and development, grouting holes, and monitoring wells. They can employ various drilling techniques, including air down-the-hole hammer drilling, mud drilling, and can be combined with wireline coring. Currently, this type of drilling rig on the market is available in two forms: diesel-driven and electric-driven (electric drive rigs are equipped with a small-power diesel power module to handle track movement). However, they have the following disadvantages:

[0003] 1. The overall transport length is relatively long. Due to structural requirements, the upper part of the drilling mast is much longer than the lower tracked chassis. In addition, the overall weight of the machine is relatively large. Using its own tracks to move the upper and lower flatbed trucks poses a great risk of tipping over due to the high center of gravity.

[0004] 2. Due to the requirement of relevant national road transport regulations that the height of goods transported should not exceed 4.5 meters, special flatbed trucks with a platform height of 300mm or 400mm are required for relocation. This places strict requirements on the chassis height of the relocation vehicles, resulting in higher transportation costs.

[0005] 3. Currently, the driller's cab of most crawler drilling rigs on the market requires disassembly and reassembly of related hydraulic or electrical control pipelines every time the rig is moved. This is cumbersome, reduces the service life of related connectors, and increases transportation and disassembly costs during both relocation and well site setup.

[0006] 4. The electric-driven crawler drilling rig uses two power modules that work independently. The main motor power module provides drilling power for the entire hydraulic system of the drilling rig, while the diesel power module provides power for the crawler to move. When the equipment is drilling, if the main motor power module fails, the drilling rig will lose drilling power, which can easily lead to drilling accidents such as stuck drill bits and bring drilling risks.

[0007] Therefore, there is an urgent need for a deep-well tracked electric-driven drilling rig and transportation method that can solve the above-mentioned shortcomings. Summary of the Invention

[0008] The purpose of this invention is to provide a deep well tracked electric-driven drilling rig and its transportation method, aiming to solve the technical problems of traditional deep well tracked drilling rigs, such as high overall transport height, high center of gravity, cumbersome disassembly and assembly of the driller's cab, and easy failure of a single drilling power source.

[0009] To achieve the above objectives, in a first aspect, the present invention provides a deep well tracked electric-driven drilling rig, comprising:

[0010] The tracked traveling mechanism includes a left track traveling unit and a right track traveling unit, and a chassis bracket for connecting the left and right track traveling units. The chassis bracket has two recessed receiving grooves, and the two receiving grooves are symmetrically arranged.

[0011] The chassis platform includes a platform body and two chassis crossbeams disposed on the bottom surface of the platform body. The two chassis crossbeams are respectively disposed in two receiving slots of the chassis bracket.

[0012] Four sets of support leg assemblies are respectively set at the four corners of the frame platform. Each support leg assembly includes a lateral telescopic arm and a vertical telescopic support leg connected to the telescopic end of the lateral telescopic arm. The telescopic end of the lateral telescopic arm is connected to the frame platform.

[0013] The power module, mounted on the chassis platform, includes an electric motor and a diesel engine. The diesel engine is electrically connected to the hydraulic pump of the tracked walking mechanism and also electrically connected to the main hydraulic pump of the overall hydraulic system. The electric motor is electrically connected to the main hydraulic pump.

[0014] The drilling mast mechanism, mounted on the chassis platform, is used to perform drilling and excavation operations.

[0015] As a further improvement to the above solution, the deep well tracked electric drilling rig also includes a driller's cab, which is rotatably mounted outside the vertical telescopic outrigger of one of the outrigger assemblies.

[0016] As a further improvement to the above solution, the driller's cab is rotatably mounted outside the vertical telescopic outrigger of the outrigger assembly via a rotating structure.

[0017] The rotatable structure includes a sleeve fitted on the outer wall of the vertical telescopic outrigger and a rotating pile rotatably fitted on the outside of the sleeve, the rotating pile being connected to the driller's chamber.

[0018] As a further improvement to the above solution, the driller's cab includes a mounting bracket and an operating room body connected to the mounting bracket;

[0019] The rotating pile is connected to the mounting bracket, and the mounting bracket is also provided with a transport fixing pin. Correspondingly, the chassis platform is provided with a pin hole that matches the transport fixing pin, so as to fix the driller's cab during transportation.

[0020] As a further improvement to the above solution, the drilling mast mechanism includes a mast, a wellhead working platform detachably mounted on the mast, and a rotating arm mounted on the side of the mast, wherein a hydraulic tongs is detachably connected to the rotating arm.

[0021] As a further improvement to the above solution, the lateral telescopic arm includes at least one lateral arm section and a lateral telescopic cylinder connected to the lateral arm. The lateral arm is telescopically disposed within the vehicle frame platform. The telescopic end of the lateral telescopic cylinder is fixedly connected to the vehicle frame platform, and the telescopic end is provided to extend into the lateral arm and connect to the lateral arm.

[0022] Furthermore, the telescopic end of the horizontal arm is provided with a connecting structure for connecting the vertical telescopic support leg.

[0023] As a further improvement to the above solution, the vertical telescopic outrigger is a vertical hydraulic cylinder, the telescopic end of the vertical hydraulic cylinder is set towards the ground, and its telescopic end is also hinged to a support for contacting the ground.

[0024] The driller's chamber is rotatably mounted outside the cylinder of the vertical hydraulic cylinder.

[0025] As a further improvement to the above solution, the motor is located at the end of the chassis platform away from the driller's chamber, and is used to provide power to the hydraulic main pump of the whole machine's hydraulic system;

[0026] The diesel engine is suspended at the rear end of the chassis platform and provides power to the tracked walking mechanism when the vehicle is moving. If the motor fails or there is a high power demand, the motor power is switched to the diesel engine or the diesel engine power is combined with the motor to provide drilling power for drilling operations.

[0027] Secondly, the present invention also provides a method for transporting a deep well tracked electric drilling rig as described in the first aspect, the steps of which include:

[0028] S1. Remove the detachable parts from the drilling mast mechanism so that the height and weight of the whole machine are lower than the national road transport regulations.

[0029] S2. First, control the horizontal telescopic arms of the four outrigger assemblies to drive the vertical telescopic outriggers to extend outwards respectively, and make the center distance between the left and right vertical telescopic outriggers greater than the width of the transport flatbed; then control the vertical telescopic outriggers to lift the whole machine, so that the net height of the track off the ground is greater than the height of the transport flatbed.

[0030] S3. The transport flatbed truck is tilted into the space formed between the tracks and the ground and positioned in the designated location;

[0031] S4. First, control the vertical telescopic outriggers to retract and fold up, placing the entire machine on the transport flatbed; then control the horizontal telescopic arm to retract, making the width of the entire machine less than the national road width limit.

[0032] Then start the transport truck to transport the deep well tracked electric drilling rig to the designated location, and repeat step S2 to drive the transport truck away.

[0033] As a further improvement to the above scheme, in step S4, after controlling the lateral telescopic boom to retract to the designated position, check and confirm that the driller's cab is housed at the head end of the machine (with the forward direction as a reference).

[0034] If the driller's cab is not housed at the head end of the machine, rotate the driller's cab to house it at the head end of the machine, and connect it to the chassis platform via a transport fixing pin.

[0035] If the driller's cab is housed at the head end of the machine, check whether the transport fixing pin connects the driller's cab to the chassis platform to ensure that the driller's cab cannot be rotated during transportation.

[0036] Because the present invention adopts the above technical solutions, the beneficial effects of this application are as follows:

[0037] 1. This invention provides a deep well tracked electric-driven drilling rig. By installing a support leg assembly on the chassis platform, the support leg assembly includes a lateral telescopic arm and a vertical telescopic leg, allowing the support leg assembly to extend in the left and right directions of the machine body and to extend and retract vertically. This configuration allows for easy transport; during transport, the machine body can be lifted by the support leg assembly, and the transport trolley can be quickly moved into the supported space. Once the designated position is reached, the support leg assembly is retracted, placing the entire machine on the transport trolley. Similarly, when unloading, the machine body is lifted by the support leg assembly, and the transport trolley moves away, enabling rapid unloading. The support leg assembly allows the drilling rig to quickly load and unload the transport trolley. Compared to traditional loading and unloading methods (driven by a tracked walking mechanism), this avoids the problem of tipping over due to a high center of gravity. Therefore, the method of lifting the machine body with the support leg assembly and moving the transport trolley for loading and unloading is safer and more convenient.

[0038] Furthermore, to meet the height, width, and weight requirements of the entire machine during transportation and comply with national road transport regulations, this invention incorporates two receiving slots on the chassis bracket. The chassis crossbeams of the vehicle platform are correspondingly positioned within these slots, thereby reducing the platform's horizontal height and the installation height of the power module. This effectively lowers the overall machine height, meeting national road transport height requirements. The installation of outrigger assemblies on the vehicle platform facilitates loading and unloading of transport flatbed trucks and also reduces the machine's width (by using a lateral telescopic boom, the outrigger assemblies can extend during construction, increasing the contact area with the ground without requiring increased spacing between the two left and right tracked units). To improve construction stability, the machine width can be reduced. In some preferred embodiments, the drilling mast mechanism includes a mast, a wellhead working platform detachably mounted on the mast, and a hydraulic tongs detachably mounted on the mast via a swing arm. This configuration allows the wellhead working platform and hydraulic tongs to be disassembled before transportation and transported using other equipment, thereby reducing the overall weight and meeting national road transport regulations. Upon arrival at the construction site, the wellhead working platform and hydraulic tongs are then reinstalled in their respective positions for construction operations. This configuration, while meeting national road transport regulations, also relaxes special requirements for transport flatbed trucks due to the reduction in width and overall weight, significantly reducing transportation costs.

[0039] Furthermore, the power module of this invention includes an electric motor and a diesel engine. The diesel engine is electrically connected to the hydraulic pump of the tracked walking mechanism and also electrically connected to the main hydraulic pump of the overall hydraulic system. The electric motor is electrically connected to the main hydraulic pump. This configuration allows the diesel engine to be connected to the main hydraulic pump of the overall hydraulic system as an emergency power source. When the working motor of the drilling rig fails, the power can be switched to the diesel engine, thereby avoiding drilling accidents such as stuck drill bits. At the same time, for working conditions with high power requirements, the diesel engine can be integrated into the electric motor power unit to ensure drilling safety while improving drilling efficiency.

[0040] 2. The present invention provides a deep well tracked electric drive drilling rig, which further includes a driller's cab. The driller's cab is rotatably mounted outside the vertical telescopic outrigger of a leg assembly via a rotating structure. The rotatable structure includes a sleeve fitted on the outer wall of the vertical telescopic outrigger and a rotating pile rotatably fitted outside the sleeve. The rotating pile is connected to the driller's cab; the driller's cab includes a mounting bracket and an operating room body connected to the mounting bracket; the rotating pile is connected to the mounting bracket, and the mounting bracket is also equipped with a transport fixing pin; the present invention cleverly sets the driller's cab rotatably outside the vertical telescopic outrigger of a leg assembly. During transportation, the driller's cab can be stored and combined, and fixed to the chassis platform by the transport fixing pin; during construction operations, after releasing the fixing, the driller's cab can be rotated and unfolded, and the operator can operate the equipment in the driller's cab, avoiding the need for the operator to operate in the harsh outdoor environment; at the same time, when setting up the equipment at the conversion site or well site, it is only necessary to rotate the driller's cab to a suitable position, thereby achieving the purpose of rapid movement and rapid on-site setup, which is more user-friendly and reduces construction and transportation costs; and the setting of the driller's cab makes it easy to set up the driller's operating handle inside, thereby reducing the difficulty of operation and the intensity of work.

[0067] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0068] Example 1

[0069] See Figure 1-8 This invention provides a deep well tracked electric-driven drilling rig, comprising:

[0070] The tracked traveling mechanism 1 includes a left tracked traveling unit 11 and a right tracked traveling unit 12, and a chassis bracket 13 for connecting the left and right tracked traveling units 12. The chassis bracket 13 is provided with two receiving grooves 14, and the two receiving grooves 14 are symmetrically arranged.

[0071] The chassis platform 2 includes a platform body 21 and two chassis crossbeams 22 disposed on the bottom surface of the platform body 21. The two chassis crossbeams 22 are respectively disposed in the two receiving slots 14 of the chassis bracket 13.

[0072] Four sets of support leg assemblies 3 are respectively arranged at the four corners of the frame platform 2. Each support leg assembly 3 includes a lateral telescopic arm 31 and a vertical telescopic support leg 32 connected to the telescopic end of the lateral telescopic arm 31. The telescopic end of the lateral telescopic arm 31 is connected to the frame platform 2.

[0073] The power module 4 is mounted on the chassis platform 2 and includes an electric motor 41 and a diesel engine 42. The diesel engine 42 is electrically connected to the hydraulic pump of the tracked walking mechanism 1 and also electrically connected to the main hydraulic pump of the whole machine's hydraulic system. The electric motor 41 is electrically connected to the main hydraulic pump.

[0074] The drilling mast mechanism 5 is mounted on the chassis platform 2 and is used to perform drilling and drilling operations;

[0075] This invention features a support leg assembly 3 mounted on the chassis platform 2. The support leg assembly 3 includes a lateral telescopic arm 31 and a vertical telescopic leg 32, allowing it to extend laterally and vertically. This configuration enables the machine body to be lifted during transport, allowing the transport trolley 9 to be quickly lowered into the supported space. Once the designated position is reached, the support leg assembly 3 is retracted, placing the entire machine on the transport trolley 9. Similarly, when disembarking, the support leg assembly 3 lifts the machine body, allowing the transport trolley 9 to move away quickly. The support leg assembly 3 allows the drilling rig to quickly load and unload the transport trolley 9. Compared to traditional loading and unloading methods (driven by a tracked walking mechanism 1), this avoids the risk of tipping over due to a high center of gravity. Therefore, this invention's method of lifting the machine body with the support leg assembly 3 and moving the transport trolley 9 for loading and unloading is safer and more convenient.

[0076] In addition, to meet the height, width, and weight requirements of the entire machine during transportation and comply with national road transport regulations, this invention incorporates two receiving slots 14 on the chassis bracket 13. The chassis crossbeam 22 of the vehicle frame platform 2 is correspondingly positioned within these slots, thereby reducing the planar height of the vehicle frame platform 2 and the installation height of the power module 4. This effectively lowers the overall height of the machine, meeting the height requirements stipulated by national road regulations. Furthermore, the installation of outrigger assemblies 3 on the vehicle frame platform 2 facilitates the loading and unloading of the transport flatbed 9 and also reduces the width of the machine body (by providing a lateral telescopic arm 31, the outrigger assemblies 3 can be extended during construction, increasing the contact area with the ground, eliminating the need to increase the spacing between the two left and right tracked walking units 12 to improve construction stability, thus reducing the machine body width).

[0077] In some preferred embodiments, the drilling mast mechanism 5 includes a mast 51, a wellhead working platform 52 detachably mounted on the mast 51, and a hydraulic tongs 53 detachably mounted on the mast 51 via a swing arm 43. This configuration allows the wellhead working platform 52 and hydraulic tongs 53 to be disassembled before transportation and transported using other equipment, thereby reducing the overall weight and meeting national road transport regulations. Upon arrival at the construction site, the wellhead working platform 52 and hydraulic tongs 53 are then reinstalled in their respective positions for construction operations. This configuration, while meeting national road transport regulations, also relaxes the special requirements for the transport flatbed truck 9 due to the reduction in width and overall weight, significantly reducing transportation costs.

[0078] Furthermore, the power module 4 of the present invention includes an electric motor 41 and a diesel engine 42. The diesel engine 42 is electrically connected to the hydraulic pump of the tracked walking mechanism 1 and also electrically connected to the main hydraulic pump of the whole machine's hydraulic system. The electric motor 41 is electrically connected to the main hydraulic pump. With this configuration, by also connecting the diesel engine 42 to the main hydraulic pump of the whole machine's hydraulic system as an emergency power source, when the drilling rig's working power motor 41 fails, the power can be switched to the diesel engine 42, thereby avoiding drilling accidents such as stuck drill bits. At the same time, for working conditions with high power requirements, the diesel engine 42 is integrated into the power unit of the electric motor 41, ensuring drilling safety while improving drilling efficiency.

[0079] As a preferred embodiment, see Figure 4 , Figure 7 and Figure 8 The deep well tracked electric drive drilling rig also includes a driller's cab 6, which is rotatably mounted outside the vertical telescopic outrigger 32 of the outrigger assembly 3 via a rotating structure.

[0080] Specifically, the rotatable structure includes a sleeve 7 sleeved on the outer wall of the vertical telescopic outrigger 32 and a rotating pile 8 rotatably sleeved on the outside of the sleeve 7. The rotating pile 8 is connected to the driller's chamber 6. In this embodiment, the sleeve 7 is installed on the outer wall of the vertical telescopic outrigger 32 of the left rear outrigger assembly 3 of the chassis platform 2 by welding.

[0081] The rotating pile 8 includes a rotating sleeve rotatably sleeved outside the sleeve 7, and a connecting plate extending from the outer wall of the rotating sleeve. The driller's chamber 6 is connected to the rotating pile 8 through the connecting plate.

[0082] This invention ingeniously places the driller's cab 6 rotatably on the outside of the vertical telescopic outrigger 32 of the outrigger assembly 3, using the rotating pile 8 as the rotation point, allowing the driller's cab 6 to quickly switch postures during transportation and operation. During transportation, the driller's cab 6 can be stored and combined, and fixed to the chassis platform 2 by the transportation fixing pin 63. During construction operations, after releasing the fixing, the driller's cab 6 can be rotated and unfolded, allowing operators to operate the equipment from inside the driller's cab 6, avoiding the need for operators to operate in harsh outdoor environments. At the same time, when setting up equipment at conversion sites or well sites, it is only necessary to rotate the driller's cab 6 to a suitable position, thereby achieving the purpose of rapid relocation and rapid on-site setup, which is more user-friendly and reduces construction and transportation costs. Furthermore, the setting of the driller's cab 6 facilitates the installation of the driller's operating handle inside, thereby reducing the difficulty of operation and the intensity of work.

[0083] As a preferred embodiment, see Figure 10-12 The rotating arm 53 includes a base 531 and a rotating cylinder 532 rotatably connected to the base 531. A connecting frame is also provided on the outer wall of the rotating cylinder 532.

[0084] The end of the connecting frame away from the rotating cylinder 532 is provided with a connecting sleeve 533 for detachable connection with the hydraulic pliers 54; correspondingly, the connecting sleeve 533 is also provided with a locking mechanism.

[0085] The hydraulic pliers 54 includes a hydraulic pliers body 541 and a connecting post 542 connected to the hydraulic pliers body 541. The connecting post 542 can be fitted into the connecting sleeve 533 to realize the detachable connection between the hydraulic pliers 54 and the rotating arm 53.

[0086] Specifically, in this embodiment, the rotating cylinder 532 is rotatably connected to the base 531 via a worm gear rotary drive device; the cross-section of the connecting sleeve 533 is square, and the cross-section of the corresponding connecting post 542 is square, matching the shape of the connecting sleeve 533; the locking mechanism includes a first locking hole 534 disposed at the bottom of the connecting sleeve 533, a second locking hole 543 correspondingly disposed on the connecting post 542, and a locking pin 535. During connection, the connecting post 542 of the hydraulic pliers 54 is fitted inside the connecting sleeve 533, and the first locking hole 534 and the second locking hole 543 are matched. The locking pin 535 passes through the first locking hole 534 and the second locking hole 543 in sequence, thereby connecting the hydraulic pliers 54 and the rotating arm 53; when disassembly is required, simply pull out the locking pin 535 to detach the hydraulic pliers 54 from the rotating arm 53.

[0087] As a preferred embodiment, see Figure 7The driller's cab 6 includes a mounting bracket 61 and an operating cab body 62 connected to the mounting bracket 61;

[0088] The rotating pile is connected to the mounting bracket 61, and the mounting bracket 61 is also provided with a transport fixing pin 63. Correspondingly, the chassis platform 2 is provided with a pin hole that matches the transport fixing pin 63 so as to fix the driller's chamber 6 during transportation.

[0089] In some embodiments, a locking mechanism can also be provided on the rotating sleeve of the rotating pile 8. When it is necessary to switch the position and attitude of the driller's chamber 6, the locking mechanism is released and the chamber is rotated to the required position, and then the current state is locked by the locking mechanism.

[0090] During operation, the driller's cab 6 can extend and retract outward along with the outrigger assembly 3. At the same time, the driller's cab 6 can rotate around the outrigger assembly 3 with the rotating pile 8 as the rotation point. According to the on-site operation requirements, a suitable angle for observing the wellhead operation can be selected. No disassembly is required, and transportation and operation layout can be quickly realized.

[0091] As a preferred embodiment, see Figure 1 and Figure 7 The lateral telescopic arm 31 includes at least one lateral arm section and a lateral telescopic cylinder connected to the lateral arm. The lateral arm is telescopically mounted within the vehicle frame platform 2. The end of the lateral telescopic cylinder furthest from the telescopic end is fixedly connected to the vehicle frame platform 2, and the telescopic end extends into the lateral arm and connects to the lateral arm. The lateral telescopic arms 31 on the left and right corresponding sides of the vehicle frame platform 2 are arranged in a straight line or a V-shape.

[0092] Furthermore, the telescopic end of the horizontal arm is provided with a connecting structure for connecting to the outer wall of the vertical telescopic leg 32; specifically, the connecting structure includes a first connecting plate disposed at the telescopic end of the horizontal arm and a second connecting plate disposed on the outer wall of the vertical telescopic leg 32, and the first connecting plate and the second connecting plate are connected by welding or bolting.

[0093] As a preferred embodiment, see Figure 1 The vertical telescopic outrigger 32 is a vertical hydraulic cylinder. The telescopic end of the vertical hydraulic cylinder is set towards the ground, and its telescopic end is also hinged to a support for contacting the ground.

[0094] The driller's chamber 6 is rotatably mounted outside the cylinder of the vertical hydraulic cylinder;

[0095] Specifically, the sleeve 7 is welded to the outside of the cylinder of the vertical cylinder, and the second connecting plate is welded to the cylinder of the vertical cylinder.

[0096] As a preferred embodiment, see Figure 8The motor 41 is located at the end of the chassis platform 2 away from the driller's chamber 6, and is used to provide power to the hydraulic main pump of the whole machine hydraulic system. The hydraulic main pump connects the hydraulic power to the drilling rig's working power, which can meet the requirements of power head rotation and braking, and can also realize the lifting of the power head.

[0097] The diesel engine 42 is suspended at the rear end of the chassis platform 2. When moving, it provides power to the tracked walking mechanism 1. If the motor 41 fails or there is a high power demand, the power of the motor 41 is switched to the diesel engine 42 or the power of the diesel engine 42 is integrated into the motor 41 to provide drilling power for drilling operations. The diesel engine 42 can also be used as an emergency power source to ensure drilling safety.

[0098] Example 2

[0099] See Figure 9 The present invention also provides a method for transporting a deep well tracked electric drilling rig as described in Embodiment 1, the steps of which include:

[0100] S1. Remove the detachable parts from the drilling mast mechanism 5 so that the height and weight of the whole machine are lower than the national road transport regulations.

[0101] S2. First, control the horizontal telescopic arms 31 of the four outrigger components 3 to drive the vertical telescopic outriggers 32 to extend outward respectively, and make the center distance between the left and right vertical telescopic outriggers 32 greater than the width of the transport flatbed 9; then control the vertical telescopic outriggers 32 to support the whole machine, so that the net height of the track off the ground is greater than the height of the transport flatbed 9.

[0102] S3. The transport flatbed truck 9 is poured into the space formed between the track and the ground and is positioned in the designated location;

[0103] S4. First, control the vertical telescopic outriggers 32 to retract and fold up, placing the entire machine on the transport flatbed 9; then control the horizontal telescopic arm 31 to retract, making the width of the entire machine less than the national road width limit.

[0104] Then start the transport trolley 9 to transport the deep well tracked electric drilling rig to the designated location, and repeat step S2. The transport trolley 9 then leaves, completing the loading and unloading process.

[0105] The transportation method provided by this invention involves first lifting the machine body using the outrigger assembly 3, allowing the transport trolley 9 to quickly tilt into the supported space. Once the designated position is reached, the outrigger assembly 3 is retracted, placing the entire machine on the transport trolley 9. Upon reaching the destination, disembarking is similarly achieved by first lifting the machine body using the outrigger assembly 3, then moving the transport trolley 9 away for rapid disembarkation. This method cleverly switches the moving body, replacing the traditional method of driving the machine onto and off the transport trolley 9 via the tracked walking mechanism 1. Instead, it uses the outrigger assembly 3 to lift the machine body off the ground, providing at least the height of the trolley. The transport trolley 9 tilts in or out to facilitate loading and unloading. This method enables rapid loading and unloading while avoiding the risk of tipping over due to the machine's high center of gravity when driven by the tracked walking mechanism 1. This makes the transportation method provided by this invention safer and more reliable.

[0106] In a preferred embodiment, in step S4, after controlling the lateral telescopic boom 31 to retract to the designated position, it is checked and confirmed that the driller's chamber 6 is housed at the head end of the machine (with the forward direction as a reference).

[0107] If the driller's chamber 6 is not stored at the head end of the machine, rotate the driller's chamber 6 to store it at the head end of the machine, and connect it to the chassis platform 2 by means of transport fixing pin 63;

[0108] If the driller's cab 6 is stored at the head end of the machine, check whether the transport fixing pin 63 connects the driller's cab 6 to the chassis platform 2 to ensure that the driller's cab 6 cannot be rotated during transportation.

[0109] During transportation, the driller's chamber 6 is stored at the head end of the machine without increasing its width, and can be fixed to the chassis platform 2 by the transport fixing pin 63 or the locking mechanism, ensuring safe and reliable transportation.

[0110] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
