Description

TECHNICAL FIELD

[0001] The present application relates to the field of tunnel engineering, and more particularly to a drilling machine. BACKGROUND

[0002] In the process of tunnel construction, various drilling operations such as advanced geological prediction, pipe shed support, anchor rod hole drilling, grouting reinforcement, and rescue are required. For example, the height of a double-line tunnel of a high-speed railway in China is usually 8-10 meters, and the width is usually 10-15 meters. In the construction of such large-section tunnels, the existing drilling machines cannot meet the operating height, and the operating width is insufficient. Therefore, the micro-step method must be used for construction, which requires multiple equipment repositioning operations, resulting in low construction efficiency, affecting the project progress, and the existing drilling machine structure is unreasonable. If the terrain is uneven during construction, the drilling machine will be unstable, which may cause accidents.

[0003] In addition, the existing drilling machines mostly use telescopic power devices combined with connecting shafts to drive the working arms of the drilling machines to rotate and position, so as to perform construction operations. However, these drilling machines have the problems of complex structure, small rotation range, and large space occupation. If they are used in a narrow tunnel, the construction efficiency will be low, and even drilling cannot be performed, which affects the project progress. Moreover, the positioning accuracy of the existing working arms is not high, which affects the project quality.

[0004] The present application provides a drilling machine that solves the problems of complex structure, large space occupation, and insufficient operating width of the existing engineering machinery. SUMMARY

The folding amplitude changing device is arranged on the front side of the frame platform, the rear end is connected to the middle part of the front side of the frame platform, and the front end is provided with a working beam. The folding amplitude changing device is used to adjust the position and angle of the working beam, so that the drilling equipment arranged on the working beam can perform drilling operations.

[0006] The protective cover is arranged on the upper part of the frame platform, the grouting flowmeter is arranged on the left side of the front end of the frame platform, and the operation cabinet is arranged on the right side of the front end of the frame platform. The power system includes a diesel tank, an electric motor, a hydraulic oil tank, an engine, and a hydraulic pump set. The diesel tank is arranged in the middle part of the front end of the frame platform, the electric motor is arranged in the middle part of the frame platform in a transverse manner, the hydraulic oil tank is arranged on the left side of the middle part of the frame platform and behind the electric motor, the engine is arranged in the middle part of the rear end of the frame platform in a longitudinal manner, and the hydraulic pump set is arranged in the middle part of the frame platform.

[0007] The cooling system comprises a wind cooling radiator and a water cooling radiator, the wind cooling radiator is arranged at the left side of the front end of the frame platform and behind the grouting flowmeter, and the water cooling radiator is arranged at the front end of the frame platform and behind the diesel tank.

[0008] The track chassis can easily pass through soft ground, large slopes, trenches and other obstacles, has the advantages of small turning radius and flexible turning, and is suitable for construction in various environments. The folding and amplitude device is arranged at the middle of the front side of the frame platform, which can keep the drilling machine balanced during drilling operation and prevent the drilling machine from tilting and causing accidents. The operation cabinet is arranged at the right side of the front end of the frame platform, which can facilitate the operation of the operator.

[0009] The double power system of the motor and the engine can be alternately used, and when one power system fails, the other power system can still ensure normal drilling operation, which improves the reliability of work compared with the single power system. The water cooling radiator is arranged at the left side of the water pump, which is close to the booster water pump, facilitates cooling during drilling operation, and the wind cooling radiator is arranged at the left side of the front end of the frame platform, which is used for cooling high-temperature hydraulic oil.

[0010] The PLC control cabinet is arranged at the right side of the middle of the frame platform, which makes the PLC control cabinet and each electrical equipment on the frame platform close to each other, reduces the use of cables, and can reduce equipment failure caused by line problems. The cable drum is arranged at the rear end of the frame platform, which can facilitate winding and collecting cables or releasing cables during drilling machine driving, prevent cables from being damaged due to different directions of cables and drilling machine driving directions, and reduce the friction between cables and the frame platform to protect the cables. The booster water pump is arranged at the front end of the frame platform, which makes the booster water pump close to the drilling hole, thereby reducing the length of the water pipe and facilitating the sending of the core cable and the core fish into the drilling hole.

[0011] This drilling rig places the heavier diesel tank, electric motor, and engine in the middle of the chassis platform, arranged sequentially from front to back. Other lighter equipment is symmetrically arranged on the left and right sides of the chassis platform. The layout of each piece of equipment takes into account weight distribution, which can keep the drilling rig balanced in the front-to-back and left-to-right directions. In addition, the equipment that needs to be operated and maintained is located on one side of the chassis platform, which facilitates maintenance in case of equipment failure. The proximity of devices with similar functions or connections can reduce the use of cables, water pipes, oil pipes, etc. This drilling rig has a compact structure, is highly maneuverable, has strong climbing ability, and is easy to use and maintain.

[0012] Preferably, it also includes a first valve group and a second valve group, the first valve group being located on the right front end of the chassis platform, behind the air-cooled radiator, and the second valve group being located on the left front end of the chassis platform.

[0013] The first and second valve groups serve as control components, respectively controlling different actions of the drilling rig. Based on the layout of the equipment on the drilling rig and their distance from the actuators, the positions of the first and second valve groups are rationally set. They are respectively located on both sides of the front end of the chassis platform for easy operation and maintenance. This proximity to actuators such as the folding and luffing device not only improves the response speed of the actuators but also facilitates the assembly of hydraulic hoses, reduces the use of hydraulic hoses, and results in a neat overall pipeline layout. The first and second valve groups are electrically controlled proportional multi-way valves, allowing for both manual and remote control operation of the various devices.

[0014] Preferably, it also includes a filter and a battery box. The filter is located in the middle of the chassis platform, behind the electric motor, and the battery box is located on one side of the chassis platform to provide power for starting the engine.

[0015] The filter can filter the hydraulic oil, and the battery box can provide temporary power to the equipment when the drilling rig is not connected to an external power source or the engine is not running.

[0016] Preferably, front outriggers are provided on the left and right sides of the bottom front end of the tracked chassis, and rear outriggers are provided on the left and right sides of the bottom rear end.

[0017] The front outriggers can be moved up or down by extending and retracting their hydraulic cylinders. During operation, the front outriggers extend downwards to support the ground, stabilizing the rig. The rear outriggers can be moved up or down by extending and retracting their hydraulic cylinders. During operation, the rear outriggers extend downwards to support the ground, stabilizing the rig and reducing the requirement for a level working surface.

[0018] Preferably, a platform is provided on the left side of the protective cover for operating the drilling rig and inspecting the equipment inside the protective cover. The platform allows for temporary operation of the drilling rig and maintenance of the equipment inside the protective cover.

[0019] Preferably, the protective cover is provided with heat dissipation holes. Providing heat dissipation holes on the protective cover allows for ventilation, enabling better ventilation and heat dissipation for the internal equipment and components.

[0020] Preferably, the drilling rig is equipped with a remote control device.

[0021] By setting up a remote control device, it supports both wired and wireless remote control operations. The drilling rig can be remotely controlled to move and carry out construction operations, which allows operators to work flexibly in different scenarios. Wireless remote control operation effectively avoids the safety hazards of dangerous rock masses and rockbursts that may cause injury to operators, thus protecting workers from being hit by objects, collapses, and harmful gases. Wired remote control serves as a backup plan to ensure the stability and reliability of the operation.

[0022] Preferably, the drilling rig is equipped with a load-sensing system and a data acquisition and analysis system. Therefore, it can fulfill the functions of acquiring, analyzing, and displaying advanced geological forecast data, providing real-time information on the geological conditions ahead of the drilling face, and adjusting drilling parameters based on borehole data.

[0023] This drilling rig features a flexible structure, allowing for accurate and rapid deployment of the working beam to the designated working position.

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] First, we will introduce and explain the drilling rig equipped with the folding and luffing device.

[0027] like Figures 1-8 As shown, the drilling rig 1 includes a tracked chassis 11, a frame platform 12, a folding luffing device 2, a protective cover 13, a grouting flow meter 14, an operating cabinet 15, a power system 16, a cooling system 17, a PLC control cabinet 18, and a booster water pump 19.

[0028] The tracked chassis 11 is used to drive the drilling rig 1 to move and correct the working position. The tracked chassis 11 can easily pass through soft ground and obstacles such as large slopes, ditches, etc. It has the advantages of small turning radius and flexible steering, and is suitable for construction in various environments.

[0029] Front outriggers 121 are provided on the left and right sides of the bottom front end of the tracked chassis 11, and rear outriggers 122 are provided on the left and right sides of the bottom rear end.

[0030] The front outrigger 121 can be moved up or down by extending and retracting the front outrigger cylinder. During operation, the front outrigger 121 is extended downwards to support the ground, stabilizing the vehicle body. The rear outrigger 122 can be moved up or down by extending and retracting the rear outrigger cylinder. During operation, the rear outrigger 122 is extended downwards to support the ground, stabilizing the vehicle body and reducing the requirements for the flatness of the work site for the drilling rig 1.

[0031] The chassis platform 12 is mounted on the tracked chassis 11 and is used to support various equipment.

[0032] The folding luffing device 2 is located on the front side of the chassis platform 12, with its rear end connected to the middle of the front side of the chassis platform 12. A working beam 201 is located at its front end. By rotating the folding luffing device up, down, left, and right, the position and angle of the working beam 201 can be adjusted, resulting in a larger working range and more flexible operation. This allows the drilling equipment 202, mounted on the working beam 201, to perform drilling operations, meeting the required position and angle for drilling. The detailed structure of the folding luffing device is described below.

[0033] The folding luffing device 2 is located in the middle of the front side of the chassis platform 12. When drilling, it can keep the drill rig 1 balanced and prevent the drill rig 1 from tilting and causing an accident, or causing the drilling to tilt and damage the equipment.

[0034] The working beam 201 is connected to the slewing mechanism assembly 28 on the folding and luffing device 2, and is used to realize drilling, core sampling and other operations of the drilling rig 1. The working beam 201 is composed of an upper rail, a lower rail and a power head. The upper rail is used to support the power head, allowing the power head to move forward and backward on the upper rail. The lower rail is used to support the entire working beam 201, allowing the working beam to extend and retract back and forth on the lower rail.

[0035] The slewing mechanism assembly 28 is mainly used to control the working beam 201 to rotate ±180°. The working beam 201 is mainly responsible for drilling, core sampling, and other operations. During operation, it is delivered to the designated working position through the folding and luffing device. The structure of the working beam 201 is existing technology and will not be described in detail here.

[0036] The protective cover 13 is fixedly installed above the chassis platform 12, which can protect the internal equipment components such as the motor 162, engine 164, hydraulic pump group 165, PLC control cabinet 18, and valve group, and prevent dust, falling rocks, water and other disasters from damaging the equipment.

[0037] A platform 131 is provided on the left side of the protective cover 13 for operating the drilling rig 1 and for maintaining the equipment inside the protective cover 13. The platform 131 allows for temporary operation of the drilling rig 1 and maintenance of the equipment inside the protective cover 13.

[0038] The protective cover 13 is provided with heat dissipation holes 132. The heat dissipation holes 132 on the protective cover 13 allow ventilation inside the protective cover 13, enabling better ventilation and heat dissipation for the various equipment and components inside the protective cover 13.

[0039] Grouting flow meter 14 is located on the left side of the front end of the chassis platform 12. During grouting operations, the grout source and grouting flow meter 14 are connected through a hose. When the grout flows through the grouting flow meter 14, the pressure and flow rate of the grout can be monitored in a timely manner, and the signal is transmitted back to the industrial control host. After calculation by the industrial control host, information such as pressure, flow rate, and grouting volume is displayed on the screen so that operators can more easily obtain grouting construction information.

[0040] The control cabinet 15 is located on the right side of the front end of the chassis platform 12. The control cabinet 15 is equipped with display instruments and other commonly used control and adjustment switches for construction, which can facilitate operation by the workers.

[0041] The power system 16 includes a diesel tank 161, an electric motor 162, a hydraulic oil tank 163, an engine 164, and a hydraulic pump assembly 165.

[0042] The diesel tank 161 is located at the front center of the chassis platform 12 and is used to supply diesel fuel to the engine 164, which is a diesel engine.

[0043] The electric motor 162 is located in the middle of the chassis platform 12 and is arranged laterally to keep the drilling rig 1 balanced in the left and right directions.

[0044] The hydraulic oil tank 163 is located on the left side of the middle of the chassis platform 12, behind the motor 162. It is used to supply hydraulic oil to the hydraulic pump group 165. The hydraulic oil enters the valve group and hydraulic actuator through the filter 113, thereby controlling the movement of the drilling rig and performing drilling operations.

[0045] The engine 164 is located at the middle of the rear end of the chassis platform 12, and is arranged longitudinally.

[0046] The system is equipped with a dual power system 16 consisting of an electric motor 162 and an engine 164. Each power system 16 provides power to the drilling rig 1 and can be used for drilling operations. They can be used alternately. If one power system 16 fails, the other power system 16 can still ensure normal drilling operations. Compared with a single power system 16, the use of a diesel-electric dual power drive system improves the reliability of the drilling rig 1. Using the electric power drive system during construction can reduce exhaust emissions and protect the health of the workers.

[0047] Under normal circumstances, one of the diesel-electric dual-power drive systems can be selectively activated to drive the corresponding work based on the actual situation. For example, the electric motor 162 is usually used to drive the hydraulic system of the drilling equipment 202 to drive the drilling equipment 202 to perform corresponding actions. Using the electric motor 162 is clean and environmentally friendly, which is beneficial to environmental protection. The engine 164 is mainly used to drive the drilling rig to move. Compared with the electric motor 162 drive, the engine 164 drive not only provides more powerful power, but also reduces the use of electrical wires on the chassis platform 12 and increases the service life of the cables.

[0048] The hydraulic pump assembly 165 is located in the middle of the chassis platform 12. There are two sets of hydraulic pump assemblies 165, one set is connected to the output shaft of the electric motor 162, and the other set is connected to the output shaft of the engine 164.

[0049] The cooling system 17 includes an air-cooled radiator 171 and a water-cooled radiator 172. The air-cooled radiator 171 is located on the left front end of the chassis platform 12, behind the grouting flow meter 14. The water-cooled radiator 172 is located at the front end of the chassis platform 12, behind the diesel tank 161.

[0050] The water-cooled radiator 172 is located to the left of the booster water pump 19, close to it, facilitating the cooling of the high-temperature hydraulic oil after use during drilling operations. The air-cooled radiator 171 is located on the left side of the front end of the chassis platform 12, close to the drilling equipment 202, facilitating the cooling of the high-temperature hydraulic oil after use by the drilling equipment 202. The simultaneous installation of both air-cooled and water-cooled radiators 171 ensures that the hydraulic oil temperature is reduced to a preset level. When the cooling effect of the air-cooled radiator 171 is insufficient, the water-cooled radiator 172 is used to rapidly cool the hydraulic oil. Additionally, sensors monitor the hydraulic oil temperature and adjust the cooling method accordingly, thereby reducing energy consumption.

[0051] The PLC control cabinet 18 is located on the right side of the center of the chassis platform 12, behind the motor 162. Placing the PLC control cabinet 18 on the right side of the center of the chassis platform 12, and bringing it close to the various electrical devices, reduces the use of cables, thereby reducing equipment failures caused by wiring problems.

[0052] The cable reel 110 is located on the left rear end of the chassis platform 12. It is a cable winding device for supplying power to the drilling rig 1. The cable can be wound and unwound remotely, eliminating the need for manual operation and ensuring worker safety. Positioning the cable reel 110 at the rear end of the chassis platform 12 facilitates cable winding and unwinding while the drilling rig 1 is moving. This prevents damage to the cable due to the cable's direction differing from the drilling rig's travel direction during winding and unwinding, and also reduces friction between the cable and the chassis platform 12, thus protecting the cable.

[0053] The booster water pump 19 is located at the front end of the chassis platform 12, behind the control cabinet 15. It is used to clean the hole and cool the drill bit during drilling, and to send the core cable and core retrieval tool into the hole after drilling. Positioning the booster water pump 19 at the front end of the chassis platform 12 makes it closer to the hole, thereby reducing the length of the water pipe and facilitating the sending of the core cable and core retrieval tool into the hole.

[0054] The winch 191 is mounted on the working beam of the folding luffing device and is located behind the drilling equipment. After drilling is completed, the winch 191 is positioned directly in front of the borehole. The core retrieval device, cable, and core retrieval device held by the core retrieval device can be directly retrieved without moving the winch 191.

[0055] The core retriever is a device that carries rock material to the rear of the core drill bit during drilling, supplied with drilling water. The core retriever is a device used to retrieve the core retriever. The core cable is the wire rope on winch 191, used to retrieve the core retriever.

[0056] The drilling rig 1 is also equipped with a first valve group 111 and a second valve group 112. The first valve group 111 is located on the right side of the front end of the chassis platform 12, behind the air-cooled radiator 171, and the second valve group 112 is located on the left side of the front end of the chassis platform 12.

[0057] The first valve group 111 and the second valve group 112 serve as control components, respectively used to control different actions of the drilling rig 1. Based on the layout of the various devices on the drilling rig 1 and their distance from the actuators, the positions of the first valve group 111 and the second valve group 112 are reasonably set. The first valve group 111 and the second valve group 112 are respectively set on both sides of the front end of the frame platform 12, which facilitates operation and maintenance, and makes them closer to the actuators such as the folding luffing device. This not only improves the response speed of the actuators, but also facilitates the assembly of hydraulic hoses and reduces the use of hydraulic hoses, making the overall pipeline routing neat.

[0058] The first valve group 111 and the second valve group 112 are electrically controlled proportional multi-way valves, which can be operated manually or remotely.

[0059] The drilling rig 1 is also equipped with a filter 113 and a battery box 114. The filter 113 is located in the middle of the chassis platform 12, behind the motor 162. The battery box 114 is located on one side of the chassis platform 12 and is used to provide temporary power to the drilling rig 1.

[0060] The hydraulic oil can be filtered through filter 113, and the battery box 114 can provide temporary power to the equipment when the drilling rig 1 is not connected to the power supply or the engine 164 is not started.

[0061] The drilling rig 1 is equipped with a remote control device, which includes a wired remote control and a wireless remote control dual control system, used to remotely control the movement of the drilling rig 1 and to carry out drilling operations.

[0062] This drilling rig 1 can be remotely controlled to move and drill, thereby protecting the workers and preventing the operator from being injured by falling objects, collapses, or harmful gases.

[0063] Drilling rig 1 is equipped with a load-sensing system and a data acquisition and analysis system. Therefore, it can meet the functions of acquiring, analyzing, and displaying advanced geological forecast data, understanding the geological conditions in front of the tunnel face in real time, and adjusting drilling parameters based on borehole data.

[0064] The drilling rig 1 is equipped with a load-sensitive system, which can adjust the output power of the hydraulic pump in real time according to the load size, avoiding the power waste phenomenon common in traditional hydraulic systems, thereby improving energy utilization efficiency and reducing the energy consumption of the drilling rig.

[0065] Load-sensitive systems, through precise sensors and control systems, can monitor load changes in real time and make rapid adjustments. This precise control capability makes the equipment operate more smoothly and accurately, effectively improving work efficiency and work quality.

[0066] The load-sensitive control system has lower power loss and is far more efficient than conventional hydraulic systems, thus saving energy and reducing heat generation in the hydraulic system. The load-sensitive system offers excellent operation and control, is simple and reliable, and can supply oil with a single pump while simultaneously meeting the operational requirements of multiple circuits and actuators with varying flow rates and pressures.

[0067] Drilling rig 1 is equipped with a remote transmission function, which can remotely upload real-time operating data of user platform equipment, running time of engine 164 and electric motor 162, alarm data, etc.

[0068] This drilling rig has a flexible structure, which can accurately and quickly deliver the drilling beam 201 to the designated working position, and has a large working range. It is highly versatile and can meet the construction requirements of both large and small cross-section tunnels, truly achieving multiple uses in one machine.

[0069] The drilling rig 1 has its heavier diesel tank 161, electric motor 162, and engine 164 arranged sequentially from front to back in the middle of the chassis platform 12. Other lighter equipment is symmetrically arranged on the left and right sides of the chassis platform 12. The layout of each piece of equipment takes into account weight distribution, which can keep the drilling rig 1 balanced in the front-to-back and left-to-right directions. In addition, the equipment that needs to be operated and maintained is located on one side of the chassis platform 12, which facilitates maintenance in case of equipment failure. The proximity of devices with similar functions or connections can reduce the use of cables, water pipes, oil pipes, and other pipelines. The drilling rig 1 has a compact structure, is highly maneuverable, has strong climbing ability, and is easy to use and maintain.

[0072] like Figure 12 and Figure 13As shown, the base assembly 21 is used to be fixedly installed on the frame platform 12 of the drilling rig 1, including a fixed base body 211, a mounting base connecting pin 221, a pin fixing baffle 212, and a swing cylinder connecting pin 213.

[0073] The front side of the fixed base body is provided with a mounting ear plate 214, and the right side is provided with an arm swing cylinder ear plate 215.

[0074] The mounting lug 214 is provided with mounting holes and two threaded holes for fixing baffles.

[0075] The mounting base connecting pin 221 is cylindrical, with a groove on the side wall at the top corresponding to the fixing baffle. The mounting base connecting pin 221 is vertically positioned, and its lower end is vertically inserted into the mounting hole of the mounting base ear plate 214.

[0076] The pin fixing baffle 212 is provided with bolt holes corresponding to the mounting thread holes on the mounting ear plate 214. One side of the pin fixing baffle 212 is inserted into the groove of the mounting base connecting pin 221 to fix the mounting base connecting pin 221, restrict the rotation of the mounting base connecting pin 221, and prevent the mounting base connecting pin 221 from coming out of the mounting hole.

[0077] The pin fixing baffle 212 is fixed to the mounting base ear plate 214 by bolts. The bolts pass through the mounting thread hole and the bolt hole to fix the pin fixing baffle 212 to the mounting base ear plate 214.

[0078] In this application, the structure of other ear plates is the same as that of the mounting base ear plates, the structure of other fixing baffles is the same as that of the pin fixing baffles, and the structure of other pins is the same as that of the mounting base connecting pins. The same installation and fixing method as the mounting base connecting pins is adopted, which will not be described in detail below.

[0079] The swing cylinder connecting pin 213 is vertically mounted on the arm swing cylinder ear plate 215 and is fixed by a pin fixing baffle mounted on the arm swing cylinder ear plate 215.

[0080] like Figure 14 and 15 As shown, the luffing mechanism mounting base assembly 22 includes a mounting base body 223, a swing cylinder pin 224, and two main boom pitch cylinder fixing pins 225.

[0122] The two ends of the telescopic beam pitch cylinder 262 are connected to the telescopic beam pitch cylinder pin 266 and the telescopic beam pitch cylinder fixed pin 257 respectively, thereby rotatably connecting to the telescopic beam assembly 26 and the telescopic beam mounting base assembly 25 respectively, and are used to drive the telescopic beam assembly 26 to rotate in the vertical direction along the telescopic beam fixed pin 261. The maximum angle of the telescopic beam assembly 26 swinging in the vertical direction is 15°.

[0123] There are two telescopic beam pitch cylinders 262, which are located on the left and right sides of the main beam 264 of the telescopic beam, respectively.

[0124] like Figure 11 , Figure 25 and Figure 26 As shown, the telescopic boom assembly 27 includes a telescopic boom main beam 272, a telescopic boom telescopic cylinder pin 273, and a slewing support mounting seat pitch cylinder fixing pin 274.

[0125] The upper rear end of the telescopic boom main beam 272 is provided with a slewing support mounting seat connecting bushing 275, the bottom rear end is provided with a telescopic boom telescopic cylinder ear plate 276, and the top near the front end is provided with a slewing support mounting seat pitch cylinder fixing ear plate 277.

[0126] The bottom of the telescopic boom main beam 272 is provided with a telescopic boom slide plate 278, which slides on the slide rail 263.

[0127] The telescopic boom telescopic cylinder pin 273 is mounted on the telescopic boom telescopic cylinder ear plate 276 and is fixed by the pin fixing baffle.

[0128] The pitch cylinder fixing pin 274 of the slewing support mounting base is set on the pitch cylinder fixing lug 277 of the slewing support mounting base and is fixed by the pin fixing baffle.

[0129] The telescopic boom telescopic cylinder 271 is installed inside the main beam 264 of the telescopic beam. Its two ends are connected to the telescopic boom telescopic cylinder pin 273 and the telescopic boom telescopic cylinder fixing pin 265, respectively. It is used to drive the telescopic boom to slide along the slide rail 263 in the front-back direction. The maximum distance the telescopic boom slides along the slide rail 263 in the front-back direction is 1400mm.

[0130] like Figure 9 , Figure 27 and Figure 28 As shown, the slewing mechanism assembly 28 includes a slewing support mounting base 283, a slewing support mounting base connecting pin 281, and a slewing support mounting base pitch cylinder pin 284.

[0131] The slewing support mounting base 283 has a slewing support mounting base pitch cylinder ear plate 285 on its front side and a slewing support mounting base mounting ear plate 286 on its bottom. The slewing mechanism assembly 28 has a working beam 201.

[0132] Drilling equipment 202 is mounted on the working beam and is used for drilling operations.

[0133] The slewing support mounting base connecting pin 281 is set on the slewing support mounting base mounting ear plate 286, extends in the left and right direction, and is fixed by the pin fixing baffle.

[0134] The pitch cylinder pin 284 of the slewing support mounting base is set on the pitch cylinder ear plate 285 of the slewing support mounting base and is fixed by the pin fixing baffle.

[0135] The two ends of the slewing mechanism pitch cylinder 282 are rotatably connected to the slewing support mounting seat pitch cylinder fixing pin 274 and the slewing support mounting seat pitch cylinder pin 284, respectively, to drive the slewing mechanism assembly 28 to rotate along the slewing support mounting seat connecting pin 281 in the up and down direction. The maximum angle of rotation of the slewing mechanism assembly 28 in the up and down direction is 110°.

[0136] In this invention, all structures are connected by pins inserted into mounting holes, allowing for relative rotation or oscillation between them. Hydraulic cylinders are used to connect the structures, and the working posture of the luffing mechanism is controlled by the extension and retraction of these cylinders.

[0137] When using this invention, as Figure 29 As shown, the working beam is in its highest horizontal working height state, and the folding luffing mechanism is in the following position: Figure 1The control process for transitioning from the initial state to this state is as follows: First, control the main boom pitch cylinder 232 to extend to its maximum stroke so that the front end of the main boom assembly 23 is raised to its maximum height. Then, adjust the two swing arm cylinders 252 so that the telescopic beam mounting base assembly 25 is in the neutral position. At this time, the two swing arm cylinders 252 extend to the same stroke.

[0138] Then, extend the telescopic beam pitch cylinder 262 to its maximum stroke, creating the maximum angle between the telescopic beam assembly 26 and the telescopic beam mounting base assembly 25. Extend the swing arm mechanism pitch cylinder 242, causing relative movement between the swing arm mechanism assembly 24 and the main boom assembly 23. Once the telescopic beam assembly 26 reaches a perpendicular position to the ground, the swing arm mechanism pitch cylinder 242 stops extending. Next, control the extension of the telescopic boom extension cylinder 271, causing the telescopic boom assembly 27 to extend to its maximum stroke. Finally, control the slewing mechanism pitch cylinder 282 to adjust the working beam 201 to a horizontal position. At this point, the drilling equipment's working height reaches 9 meters, and by adjusting the slewing angle of the swing cylinder 222 and the slewing mechanism assembly 28, the drilling equipment's working width reaches 1.2 meters.

[0139] like Figure 30 As shown, the working beam is perpendicular to the working face at its maximum working width, and the folding luffing mechanism is in the following state: Figure 1 The control process for transitioning from the initial state to this state is as follows: First, control the main boom pitch cylinder 232 to extend to its maximum stroke, raise the main boom assembly 23 to its maximum height, and control the swing cylinder 222 to extend to its maximum stroke.

[0140] Then, extend the tilt cylinder 242 of the swing arm mechanism to its maximum stroke. At this time, the angle between the telescopic beam assembly 26 and the ground reaches an approximately perpendicular state. Adjust the two swing arm cylinders 252 so that one extends to its maximum stroke and the other retracts to its maximum stroke, so that the telescopic beam assembly 26 is placed horizontally.

[0141] Next, the telescopic boom extension cylinder 271 is extended, causing the telescopic boom assembly 27 to extend to its maximum stroke, and the telescopic beam pitch cylinder 262 is extended to its maximum stroke, so that the telescopic beam assembly 26 and the telescopic beam mounting base assembly 25 form the maximum angle. Finally, the slewing mechanism pitch cylinder 282 is controlled to adjust the working beam 201 to be perpendicular to the working surface.

[0142] At this operating height, the drilling equipment can operate with a working width of up to 11.5 meters.

[0143] During operation, the working sequence of the folding luffing mechanism can be flexibly adjusted according to the actual terrain to prevent collisions with the chassis platform 12 or the rock wall. Since the working beam has a telescopic function, even if the working beam is still a certain distance from the working surface, it can be extended for positioning in this state.

[0144] like Figure 31 As shown, this illustrates the state of the working beam at its maximum vertical working height during radial drilling operations (i.e., working on the tunnel sidewalls). The folding luffing mechanism then... Figure 1 The control process for transitioning from the initial state to this state is as follows: First, control the main boom pitch cylinder 232 to extend to the maximum stroke to raise the main boom assembly 23 to the maximum height, and control the two swing arm cylinders 252 to keep the telescopic beam mounting base assembly 25 in the neutral position.

[0145] Then, extend the boom mechanism pitch cylinder 242 to its maximum stroke. At this time, the telescopic beam assembly 26 reaches an approximately perpendicular position with the ground, and control the telescopic boom extension cylinder 271 to extend, driving the telescopic boom assembly 27 to extend to its maximum stroke.

[0146] Next, the tilt cylinder 282 of the control slewing mechanism is used to adjust the working beam 201 to a vertical position, and the working beam 201 is extended to its maximum stroke. Finally, by controlling the extension and retraction stroke of the control arm swing cylinder 222 and the rotation angle of the slewing support, the working width of the drilling equipment at this height can reach 1.2 meters.

[0147] At this point, the drilling equipment was operating at a height of 11.5 meters.

[0148] like Figure 32 As shown, during radial drilling operations, the working beam is in its maximum working width on the horizontal working plane, and the folding luffing mechanism is in the following state: Figure 1 The control process for transitioning from the initial state to this state is as follows: First, control the main boom pitch cylinder 232 to extend to its maximum stroke, raise the main boom assembly 23 to its maximum height, and control the swing cylinder 222 to extend to its maximum stroke.

[0149] Then, extend the tilt cylinder 242 of the swing arm mechanism to its maximum stroke. At this time, the angle between the telescopic beam assembly 26 and the ground reaches an approximately perpendicular position. Adjust the two swing arm cylinders 252 so that one extends to its maximum stroke and the other retracts to its maximum stroke, so that the telescopic beam assembly 26 is placed horizontally.

[0150] Next, the telescopic boom extension cylinder 271 is controlled to extend, causing the telescopic boom assembly 27 to extend to its maximum stroke, and the slewing mechanism pitch cylinder 282 is controlled to retract to its minimum stroke. Finally, the working beam 201 is controlled to extend to its maximum stroke.

[0151] At this point, the drilling equipment has a working width of 16 meters at this working height.

[0152] Since the working beam 201 has a telescopic function, even if the working beam 201 is a certain distance away from the working surface in the above states, the working beam 201 can be controlled to extend for positioning and operation.

[0153] It should be noted that the above operating sequence is not fixed. During use, the control sequence can be flexibly adjusted according to the actual terrain and other factors to prevent collisions with the chassis platform 12 or rock walls.

[0154] This invention sets up a variable amplitude mechanism mounting base assembly 22 rotatably connected to a base assembly 21, and a swing cylinder 222 drives the variable amplitude mechanism mounting base assembly 22 to swing left and right. The telescopic beam mounting base assembly 25 is rotatably connected to the front end of the swing arm mechanism assembly 24. The swing arm cylinder 252 can drive the telescopic beam mounting base assembly 25 to rotate left and right, so that the front end of the folding variable amplitude device can rotate back and forth on the left and right sides of the front end of the drilling rig 1, thereby improving the rotation range and working width of the drilling equipment.

[0155] By rotatably connecting the rear end of the main boom assembly 23 to the luffing mechanism mounting base assembly 22, and with two main boom pitch cylinders 232 located on the left and right sides of the main boom assembly 23 respectively, the main boom assembly 23 can be driven to rotate vertically. The swing arm mechanism assembly 24 is rotatably connected to the front end of the main boom assembly 23, and the swing arm mechanism pitch cylinder 242 drives the swing arm mechanism assembly 24 to rotate vertically. The telescopic beam assembly 26 is rotatably connected to the telescopic beam mounting base assembly 25, and two telescopic beam pitch cylinders 262 are located on the left and right sides of the telescopic beam assembly 26 respectively, driving the telescopic beam assembly 26 to swing vertically. Therefore, the swing arm mechanism assembly 24 and the telescopic beam assembly 26 can be folded and retracted above the main boom assembly 23, reducing the size of the device, minimizing space occupation, and facilitating the movement and relocation of the drilling rig 1. During drilling operations, the swing arm mechanism assembly 24 and the telescopic beam assembly 26 can be extended relative to the main boom assembly 23, thereby increasing the working height and working width of the drilling equipment. To improve construction efficiency and speed up project progress when working in confined spaces like tunnels.

[0156] By installing a slide rail 263 on the top of the telescopic beam assembly 26, the telescopic arm assembly 27 is slidably mounted on the slide rail 263. The telescopic arm extension cylinder 271 can drive the telescopic arm assembly 27 to slide along the slide rail 263 in the front-to-back direction. During drilling operations, if the working beam 201 is a certain distance from the working surface, the telescopic beam assembly 26 can be controlled to slide out, thereby improving the positioning accuracy of the working arm and improving the quality of the project.

[0157] By setting the slewing mechanism assembly 28 to be rotatably connected to the telescopic arm assembly 27, the slewing mechanism assembly 28 can be driven to rotate in the up and down direction by the slewing mechanism pitch cylinder 282. The angle of the drilling equipment can be adjusted as needed to improve drilling efficiency and accuracy.

[0158] This drilling rig features a flexible structure, enabling it to accurately and quickly deliver the working beam 201 to the designated working position. It boasts a large working range; when the working beam is perpendicular to the tunnel face, the maximum working height of the drilling equipment can reach 9 meters; when the working beam is perpendicular to the tunnel face, the maximum working width of the drilling equipment can reach 12 meters; and when the radial working beam is on a horizontal working plane, the maximum working width of the drilling equipment can reach 16 meters. This drilling rig is highly versatile, meeting the construction requirements of both large and small tunnel sections, truly achieving multi-purpose functionality.

[0159] It should be noted that the above embodiments are illustrative of the present invention and not restrictive of the present invention, and that those skilled in the art can devise alternative embodiments without departing from the scope of the appended claims.
