Description

Technical Field

[0001] This utility model relates to the field of rotary drilling rig technology, and in particular to a rotary drilling rig with rod transport and fixing device and a rotary drilling rig. Background Technology

[0002] Rotary drilling rigs, as a highly efficient and flexible pile foundation construction equipment, are widely used in various construction scenarios such as building foundations and bridge pile foundations.

[0003] In the transportation of rotary drilling rigs, the traditional method is to transport them without the drill rod, meaning the drill rod is transported separately from the main unit. In this mode, transporting multiple drill rods or even just one drill rod typically requires an additional transport vehicle. This not only increases transportation costs but also involves a series of complex steps such as loading, unloading, and storage of the drill rod, reducing transportation efficiency and increasing the risk of equipment damage.

[0004] With the development of the construction industry, the requirements for construction efficiency and cost control are increasing. The rotary drilling rig with boom transport function has emerged to address this need. This function allows the drill rod to be transported together with the main unit, effectively avoiding the aforementioned problems, significantly saving transportation costs, and improving overall construction efficiency.

[0005] However, currently, the method of fixing the upper part of the mast when transporting rotary drilling rigs in the inverted mast mode generally presents safety and operational difficulties. The safety issues mainly manifest in the fact that operators need to work at heights, increasing the probability of falls and other accidents; the operational difficulties are reflected in the cumbersome and inconvenient disassembly and assembly process, which reduces the efficiency of transportation preparation work, and may even lead to equipment damage or insecure fixing due to improper operation, thereby affecting transportation safety.

[0011] According to the present invention, a rotary drilling rig with a boom is provided, wherein the number of connecting components is three, and the three connecting components are arranged in a ring array along the axis of the fixing plate on the mounting surface.

[0012] According to the present invention, a rotary drilling rig with rod transport and fixing device is provided, wherein a plurality of first fixing holes are provided on the outer periphery of the fixing plate, a second fixing hole is provided on the side of the fixing frame near the fixing plate corresponding to the first fixing hole, and a third fixing hole is provided on the side of the power head's pressure plate near the fixing plate corresponding to the first fixing hole. Fasteners are provided through the second fixing hole, the first fixing hole and the third fixing hole to fix the fixing frame and the fixing plate to the power head's pressure plate.

[0013] According to the present invention, a rotary drilling rig with rod transport and fixing device is provided. The fixing frame includes a first connecting plate, a second connecting plate, a connector, and a sleeve. The first connecting plate and the second connecting plate are spaced apart from each other. The connector is connected between the first connecting plate and the second connecting plate. The sleeve is connected to the middle part of the side of the first connecting plate away from the connector. The first connecting plate has a first opening communicating with the sleeve. The first opening is used for the square head to pass through. The second connecting plate has a second fixing hole. The middle part of the second connecting plate has a second opening corresponding to the first opening. The second opening is used for the outer rod to pass through.

[0014] According to the present invention, a rotary drilling rig with rod transport and fixing device is provided, wherein the connecting member is a connecting rod, and there are multiple connecting rods arranged around the first connecting plate and the second connecting plate.

[0015] According to the present invention, a rotary drilling rig with rod transport and fixing device is provided, wherein the fixing frame further includes a plurality of reinforcing elbow plates, which are arranged around the outer peripheral wall of the sleeve and connected between the sleeve and the first connecting plate.

[0016] This utility model also provides a rotary drilling rig, comprising: Chassis; A mast, which is rotatably connected to the chassis; A drill rod is connected to a mast. The drill rod includes an outer rod, multiple inner rods, and a core rod. The core rod is telescopically sleeved in the inner rod. The multiple inner rods are telescopically sleeved in the outer rod. The upper end of the drill rod has a flat head, and the lower end of the drill rod has a square head. A power head is movably mounted on the mast and sleeved on the drill pipe. A pressure plate is provided at one end of the power head facing the square head of the drill pipe. A follower frame, which is movably mounted on the mast and connected to the drill pipe; A lifting device, which is connected to the flat end of the drill pipe; As described in any of the above-mentioned rotary drilling rigs with boom transport and fixing devices.

[0017] This utility model provides a rotary drilling rig with a boom transport and fixing device and a rotary drilling machine. The upper end of the drill rod is sealed with an anti-collapse plate, and the lower end of the drill rod is sealed and the outer rod and the lower pressure plate of the power head are relatively fixed through a fixing plate, connecting components, and a fixing frame, ensuring the relative stability of the drill rod in the inverted mast transport state. In the mast-up state, the mast and the outer rod of the drill rod are vertical. Although the anti-collapse plate at the upper end of the outer rod is in a high position, no adjustment is required during disassembly and assembly, thus avoiding the need for high-altitude operations due to the need to operate high-position components. Simultaneously, in the mast-up state, the position of the lower pressure plate of the power head is limited by the mast structure and is typically within 1.2-2.5 meters above the ground; the drainage holes of the outer rod are correspondingly set with the connecting components at the same height as the fixing plate, also within the range directly accessible to ground operators. The connecting assembly secures the fixed plate and the outer rod via a movable insertion method, eliminating the need for complex high-altitude alignment or leverage tools. Operators can perform alignment, insertion, and tightening operations from the ground, thus avoiding the need to climb the mast. Secondly, the square head at the lower end of the outer rod is located at the very bottom of the drill pipe, flush with the drilling rig chassis or the ground when the mast is erected. Therefore, operators can perform the assembly and disassembly of the fixing device from a lower position. The upward extension of the other end of the fixing frame is ideally positioned to reach the fixed plate. Since the fixed plate itself is at a low height, the fastener connection between this end and the fixed plate and the lower pressure plate of the power head can also be completed on the ground or the low operating platform provided with the drilling rig, eliminating the need for high-altitude operations.

[0018] This allows for the connection and disassembly of various components to be completed while the rotary drilling rig is in its upright position. Operators no longer need to climb the mast for high-altitude work, avoiding potential safety risks such as falls and improving operational safety. Furthermore, the easy and quick connection of the movable components and fixing brackets via fasteners reduces the time and effort required for assembly and disassembly, thereby improving efficiency.

[0035] The following is combined Figures 1 to 9The present invention will provide a detailed description of a rotary drilling rig with a boom for transporting and fixing, and a rotary drilling machine, through specific embodiments and application scenarios.

[0036] In the embodiments of this utility model, such as Figures 1 to 8 As shown, a rotary drilling rig with rod transport and fixing device 700 includes an anti-collision plate 710, a fixing plate 720, multiple connecting components 730, and a fixing frame 740. The anti-collision plate 710 is located at the upper end of the outer rod 310 in the drill rod 300, and is used to seal the upper end of the outer rod 310. The fixing plate 720 has a central hole for the outer rod 310 to pass through. The fixing plate 720 has a mounting surface on one side along its own axis, and the other side is fitted to the lower pressure plate 410 of the power head 400. Multiple connecting components... The component 730 is disposed around the mounting surface. The connecting component 730 extends radially along the fixed plate 720 and is correspondingly disposed with the water flow hole 311 on the outer rod 310. The connecting component 730 is movably inserted into the water flow hole 311 to fix the fixed plate 720 and the outer rod 310. One end of the fixing bracket 740 is sleeved on the square head 350 at the lower end of the outer rod 310, and the other end extends upward along the axis and is connected and fixed to the fixed plate 720 and the lower pressure plate 410 of the power head 400 by fasteners.

[0037] An anti-slip plate 710 is installed at the upper end of the outer rod 310 of the drill rod 300. It seals the upper end of the outer rod 310. In the inverted mast transport state of the rotary drilling rig, this prevents components inside the drill rod 300 (such as drill bits and drilling tools) from detaching from the upper end of the outer rod 310, ensuring the integrity of the internal structure of the drill rod 300 and avoiding the impact on the reuse of the drilling rig or the creation of safety hazards due to component scattering. Simultaneously, in the mast-erect state, since it is pre-assembled at the factory, no adjustment is required when disassembling and assembling the fixing device, avoiding high-altitude operations for operators handling high-position components and reducing operational risks.

[0038] The fixed plate 720 has a central hole through which the outer rod 310 passes, a mounting surface is formed on one side along its own axis, and the other side is fitted to the lower pressure plate 410 of the power head 400.

[0039] The central hole provides a passage for the outer rod 310 to pass through, allowing the outer rod 310 to pass smoothly through the fixing plate 720, thus enabling the fixing plate 720 to be positioned and installed on the outer rod 310, and providing a basis for subsequent connection and fixation with other components.

[0040] The mounting surface serves as the mounting base for multiple connecting components 730. The connecting components 730 arranged around the mounting surface can be evenly connected and fixed to the outer rod 310 with the fixing plate 720 as the center, thereby enhancing the stability and reliability of the fixation.

[0041] After the fixing bracket 740 is connected and fixed to the lower pressure plate 410 of the power head 400, the lower pressure plate 410 of the power head 400 and the outer rod 310 can be fixed relative to each other, so that the drill rod 300 maintains a relatively stable position during transportation, preventing relative displacement between the drill rod 300 and the power head 400, and ensuring the overall structural stability of the drilling rig.

[0042] Multiple connecting components 730 are arranged around the mounting surface of the fixed plate 720, extend radially along the fixed plate 720, and are correspondingly arranged with the water flow holes 311 on the outer rod 310.

[0043] The connecting component 730 is movably inserted into the water flow hole 311 of the outer rod 310, fixing the fixing plate 720 to the outer rod 310. This movable insertion allows for quick installation and disassembly, improving efficiency. Simultaneously, the circumferentially evenly distributed connecting components 730 can fix the outer rod 310 from multiple directions, enhancing the stability of the fixation and preventing the outer rod 310 from shaking or shifting during transportation, thus ensuring the stability of the drill rod 300.

[0044] One end of the fixing bracket 740 is sleeved on the square head 350 at the lower end of the outer rod 310, and the other end extends upward along the axis and is connected and fixed to the fixing plate 720 and the pressure plate 410 of the power head 400 by fasteners.

[0045] One end of the fixing frame 740 is sleeved on the square head 350 at the lower end of the outer rod 310. By utilizing the structural characteristics of the square head 350 at the lower end of the outer rod 310, the fixing frame 740 is reliably positioned and connected at the lower end of the outer rod 310, providing a stable support foundation for the fixing frame 740.

[0046] The other end of the fixing frame 740 extends upward along the axis and is connected and fixed to the fixing plate 720 and the lower pressure plate 410 of the power head 400 by fasteners, further enhancing the connection strength between the outer rod 310 and the lower pressure plate 410 of the power head 400. It connects the fixing of the lower end of the outer rod 310 with the fixing of the upper fixing plate 720 and the lower pressure plate 410 of the power head 400, forming a complete fixing system. This ensures that the drill rod 300 can remain relatively stable during the inverted mast transportation state and will not loosen or shift due to vibration or external force.

[0047] This application uses an anti-bulging plate 710 to seal the upper end of the drill rod 300, and a fixing plate 720, connecting assembly 730, and fixing frame 740 to seal the lower end of the drill rod 300 and relatively fix the outer rod 310 to the lower pressure plate 410 of the power head 400, thereby ensuring the relative stability of the drill rod 300 in the inverted mast transport state of the rotary drilling rig. Since the mast 200 and the outer rod 310 of the drill rod 300 are vertical in the mast-standing state of the rotary drilling rig, although the anti-bulging plate 710 at the upper end of the outer rod 310 is in a high position, no adjustment is required during disassembly and assembly, thus avoiding the need for high-altitude operations due to the need to operate high-position components. Meanwhile, in the mast-erected state, the position of the lower pressure plate 410 of the power head 400 is limited by the mast 200 structure, typically ranging from 1.2 to 2.5 meters above the ground. The water outlet 311 of the outer mast 310 is correspondingly positioned with the connecting assembly 730, at the same height as the fixed plate 720, also within the range directly accessible to ground operators. The connecting assembly 730 connects and secures the fixed plate 720 and the outer mast 310 through a movable insertion method, eliminating the need for complex high-altitude alignment or leverage tools. Operators can complete alignment, insertion, and tightening actions while standing on the ground, thus avoiding the need to climb the mast 200. Secondly, the square head 350 at the lower end of the outer rod 310 is located at the bottom of the drill rod 300 and is flush with the drilling rig chassis 100 or the ground in the mast state. Therefore, the operator can complete the disassembly and assembly of the fixing device of this application from a lower position. The length of the other end of the fixing frame 740 extending upward is preferably just to reach the position of the fixing plate 720. Since the fixing plate 720 itself is at a low height, the fastener connection between this end and the fixing plate 720 and the lower pressure plate 410 of the power head 400 can also be completed on the ground or on the low operating platform of the drilling rig, and there is no need for high-altitude operation.

[0048] This allows for the connection and disassembly of various components to be completed while the rotary drilling rig 10 is in its upright position. Operators do not need to climb the mast 200 for high-altitude work, avoiding potential safety risks such as falls and improving operational safety. Simultaneously, the movable insertion of the connecting assembly 730 and the fastener connection of the fixing bracket 740 are simple and quick, reducing the time and effort required for assembly and disassembly, thereby improving efficiency.

[0049] Reference Figures 2 to 7 According to the present invention, a rotary drilling rig with rod transport and fixing device 700 is provided. The connecting component 730 includes a connecting sleeve 731 and a plug-in 732. The connecting sleeve 731 is fixedly connected to the mounting surface, and the plug-in 732 is movably installed in the connecting sleeve 731 and is movably plugged into the water flow hole 311 on the outer rod 310.

[0050] Understandably, the connecting sleeve 731 is fixed to the mounting surface of the fixed plate 720, providing a stable support and mounting platform for the connector 732. This allows the connector 732 to be accurately positioned on the fixed plate 720 at the position corresponding to the water outlet 311 of the outer rod 310, ensuring precise insertion into the water outlet 311 of the outer rod 310 during subsequent connection processes, thereby achieving a reliable connection between the fixed plate 720 and the outer rod 310.

[0051] The connector 732 is movable within the connecting sleeve 731, allowing it to be easily inserted into and removed from the drainage hole 311 of the outer rod 310 during installation and disassembly of the fixing device. Operators can complete the connection and separation simply by pushing or pulling the connector 732 without using complex tools or performing cumbersome operations, greatly improving installation and disassembly efficiency.

[0052] In some embodiments, the inner wall of the connecting sleeve 731 is provided with an internal thread, the plug 732 is a bolt, and the plug 732 is threadedly connected and fixed to the connecting sleeve 731.

[0053] Understandably, the internal thread on the inner wall of the connecting sleeve 731 engages with the bolt, which serves as the insertion piece 732. When the bolt is screwed into the connecting sleeve 731, the meshing of the threads generates significant friction and preload, tightly connecting the fixed disc 720 and the outer rod 310 together. This connection method effectively resists various external forces, such as vibration, impact, and shaking, that affect the drill pipe 300 during transportation, preventing relative displacement or loosening between the fixed disc 720 and the outer rod 310, thereby ensuring the stability and safety of the drill pipe 300 during transport.

[0054] In some embodiments, the inner hole of the connecting sleeve 731 is a smooth hole, the plug-in 732 is a pin, and a fixing hole is provided on the outer circumferential side of the connecting sleeve 731. The fixing hole communicates with the inner hole, and the fastener is connected to the pin through the fixing hole to limit the pin connection within the connecting sleeve 731.

[0055] Understandably, the fixing hole on the outer circumference of the connecting sleeve 731 communicates with the inner hole, and the fastener, by passing through the fixing hole and connecting to the pin, can effectively limit the pin's movement. When the pin is inserted into the connecting sleeve 731, the fastener can prevent the pin from coming out of the connecting sleeve 731 due to vibration or external force during transportation, ensuring the stability and reliability of the connection.

[0056] Reference Figure 6 and Figure 7 According to the present invention, a rotary drilling rig with rod transport and fixing device 700 is provided, wherein the number of connecting components 730 is three, and the three connecting components 730 are arranged in a ring on the mounting surface along the axis of the fixing plate 720.

[0057] Understandably, the three connecting components 730 are arranged in a circular array along the axis of the fixed disk 720. During transportation, when the rotary drilling rig is subjected to external forces (such as vibration or shaking), the fixed disk 720 can bear the force evenly. Because the three connecting points can form a relatively stable triangular structure, the stability of the triangle can prevent local stress concentration in the fixed disk 720 due to uneven force distribution, thereby preventing deformation or damage to the fixed disk 720 and ensuring the structural integrity of the entire fixing device during transportation.

[0058] The three connecting components 730 of the ring array more securely connect the fixing plate 720 to the rotary drilling rig, increasing the overall rigidity of the fixing device. During transportation, when encountering bumps or collisions, this increased rigidity helps reduce the relative displacement between the components of the fixing device, allowing the rotary drilling rig to be more reliably fixed to the fixing plate 720 and reducing the risk of safety accidents caused by loose components.

[0059] Reference Figure 2 According to the present invention, a rotary drilling rig with rod transport and fixing device 700 is provided, wherein a plurality of first fixing holes are provided on the outer periphery of the fixing plate 720, a second fixing hole is provided on the side of the fixing frame 740 near the fixing plate 720 corresponding to the position of the first fixing hole, and a third fixing hole is provided on the side of the power head 400's lower pressure plate 410 near the fixing plate 720 corresponding to the position of the first fixing hole. Fasteners are provided through the second fixing hole, the first fixing hole and the third fixing hole to fix the fixing frame 740 and the fixing plate 720 to the lower pressure plate 410 of the power head 400.

[0060] Understandably, fasteners are sequentially inserted through the second, first, and third fixing holes, tightly connecting the fixing frame 740, the fixing plate 720, and the lower pressure plate 410 of the power head 400 together to form a stable overall structure. This structure can withstand various external forces generated by the rotary drilling rig during transportation, such as vibration, impact, and swaying, ensuring that there is no relative displacement or separation between the components of the fixing device, thereby guaranteeing the stability and safety of the rotary drilling rig during transportation.

[0061] The multiple fixing holes ensure a more even distribution of connection points, distributing the force acting on the fixing device evenly across all connection parts. Compared to designs with a single or few connection points, this avoids localized stress concentration, reduces the risk of damage to connection parts due to excessive force, and improves the overall strength and durability of the fixing device.

[0062] Reference Figure 2 and Figure 3According to the present invention, a rotary drilling rig with rod transport and fixing device 700 is provided. The fixing frame 740 includes a first connecting plate 741, a second connecting plate 742, a connector 743, and a sleeve 744. The first connecting plate 741 and the second connecting plate 742 are arranged at intervals. The connector 743 is connected between the first connecting plate 741 and the second connecting plate 742. The sleeve 744 is connected to the middle part of the side of the first connecting plate 741 away from the connector 743. The first connecting plate 741 is provided with a first opening communicating with the sleeve 744. The first opening is used for passing through the square head 350. The second connecting plate 742 is provided with a second fixing hole. The middle part of the second connecting plate 742 is provided with a second opening corresponding to the first opening. The second opening is used for passing through the outer rod 310.

[0063] It is understandable that the first connecting plate 741 and the second connecting plate 742 are spaced apart from each other and connected by the connector 743 to form the basic frame structure of the fixing frame 740.

[0064] The connector 743 connects the first connecting plate 741 and the second connecting plate 742 into a whole, so that the force is evenly transmitted between the two, avoiding local stress concentration that could lead to structural damage, and improving the load-bearing capacity and service life of the fixing frame 740.

[0065] Sleeve 744 is connected to the middle of the side of the first connecting plate 741 opposite to the connector 743, providing a precise positioning and a stable connection point for the connection with the square head 350. Sleeve 744 is connected to the first connecting plate 741, ensuring accurate connection between the square head 350 and the fixing bracket 740, and the constraint effect of sleeve 744 limits the movement of the core rod 330 connected to the square head 350.

[0066] The first connecting plate 741 has a first opening communicating with the sleeve 744 for the square head 350 to pass through. This allows the square head 350 to smoothly pass through the first connecting plate 741 and enter the sleeve 744, achieving a quick and accurate connection between the square head 350 and the fixing bracket 740. Simultaneously, the size and shape of the first opening match the square head 350, providing guidance and constraint to the square head 350, further improving the reliability of the connection.

[0067] The second connecting plate 742 has a second fixing hole for connecting with other components such as the fixing plate 720. By using fasteners through the second fixing hole, the fixing frame 740 can be firmly fixed to the fixing plate 720, making the fixing frame 740 an important component of the entire transport fixing device. The position and number of the second fixing holes are designed according to actual connection requirements, ensuring the connection strength and stability between the fixing frame 740 and other components.

[0068] The second connecting plate 742 has a second opening in the middle corresponding to the first opening, for the outer rod 310 to pass through. This allows the outer rod 310 to pass smoothly through the second connecting plate 742, forming a reasonable layout with the square head 350 within the fixing frame 740.

[0070] Understandably, the multiple connecting rods, which connect to the first connecting plate 741 and the second connecting plate 742, form a truss-like structural system. This significantly enhances the overall rigidity of the fixing frame 740, making it less prone to deformation when subjected to various external forces generated during the transport of the rotary drilling rig. This ensures the stability of the shape and dimensions of the fixing frame 740, providing reliable support for the rotary drilling rig. Simultaneously, the connection method of the connecting rods also provides a basis for the operation of the connecting components 730 or fasteners.

[0071] Reference Figure 3 According to the present invention, a rotary drilling rig with rod transport and fixing device 700 is provided. The fixing frame 740 further includes a plurality of reinforcing elbow plates 745. The plurality of reinforcing elbow plates 745 are arranged around the outer peripheral wall of the sleeve 744 and connected between the sleeve 744 and the first connecting plate 741.

[0072] Understandably, the reinforced elbow plate 745 can significantly enhance the connection strength between the sleeve 744 and the first connecting plate 741, prevent loosening or deformation caused by external forces, and ensure the stability of the sleeve 744 during transportation.
