[0028] To address the problem of existing rescue drilling rigs being large and complex, making them difficult to transport and relocate quickly in confined spaces, the basic technical concept of this invention is to modularize the frame of the rescue drilling rig. The frame is divided into three sections from front to back, and these three sections are detachable and can each carry or install different functional equipment. During rescue operations, each module of the rescue drilling rig can be transported to the site individually and assembled on-site to meet rapid rescue needs.

[0029] Based on the above concept, the present invention will be further described in detail below with reference to the embodiments.

[0030] Specific embodiments of the mobile rescue drilling rig provided by this invention: The mobile rescue drilling rig (hereinafter referred to as the drilling rig) provided in this embodiment is as follows: Figure 1 As shown, it includes a frame 1, which serves as the foundation for the drilling rig, and various functional devices can be mounted on the frame 1. In essence, consistent with existing technologies, the drilling rig in this embodiment can also horizontally drill through the collapsed body during rescue operations. After penetrating the collapsed body, the inner spiral shaft 5 located in the outer sleeve 3 is extracted, and the space inside the outer sleeve 3 forms a rescue channel.

[0031] Specifically, the frame 1 is equipped with an outer tube drive 6 (power head) and an inner spiral shaft drive 7 (power head). The outer tube drive 6 is used to drive the outer tube 3 to rotate, and the inner spiral shaft drive 7 is used to drive the inner spiral shaft 5 to rotate. It includes a drive motor (or hydraulic motor), a reducer, a slewing bearing, etc. The outer tube drive 6 and the inner spiral shaft drive 7 are coaxial.

[0032] To enable the forward drilling of the outer tube 3 and the inner spiral shaft 5, both the outer tube drive 6 and the inner spiral shaft drive 7 are mounted on the frame 1 in a way that allows them to move back and forth. Correspondingly, the frame 1 is provided with a translational guide structure, such as a slide rail structure, to guide the outer tube drive 6 and the inner spiral shaft drive 7 in a forward and backward movement. Sliding blocks are then installed on the outer tube drive 6 and the inner spiral shaft drive 7. Simultaneously, propulsion cylinders are connected between the outer tube drive 6 and the frame 1, and between the inner spiral shaft drive 7 and the frame 1. These propulsion cylinders, which push and pull the outer tube drive 6 and the inner spiral shaft drive 7 forward and backward, can be arranged alternately on the left and right sides, i.e., as shown in the diagram. Figure 7 The external propulsion cylinder 11 and the internal propulsion cylinder 12 shown in the figure can be referred to the prior art for their specific configuration, which will not be described in detail here.

[0033] Depending on the length of the collapsed body to be drilled, the outer casing 3 and the inner spiral shaft 5 can be continuously connected. At the most basic level, the front end of one section of the inner spiral shaft 5 is equipped with a rock-breaking head. The excavated soil generated during the forward drilling process can be discharged backward from the outer casing 3 as the inner spiral shaft 5 rotates.

[0034] When connecting the outer sleeve 3 and the inner spiral shaft 5, to prevent the front outer sleeve 3 from rotating, such as... Figure 1 and Figure 8 As shown, a pipe clamping device 4 is also provided on the frame 1. The pipe clamping device 4 is equipped with a pipe clamping mechanism 405 that can clamp and hold the outer sleeve 3. During normal drilling, the pipe clamping mechanism 405 needs to be separated from the outer sleeve 3.

[0035] A tracked walking mechanism 2 is also provided on the frame 1 to enable the drilling rig to move normally on uneven roads and ensure its passability. The specific structural components of the tracked walking mechanism 2 are consistent with the prior art and will not be described in detail here.

[0036] In addition, auxiliary equipment is also installed on frame 1. This auxiliary equipment can be configured according to the drilling rig's operational needs. For example, it may include a power source, crane, and control box.

[0037] As explained above, rescue drilling rigs integrate numerous functional devices and have a complex structure. However, for narrow tunnels (tunnels), the entire rescue drilling rig cannot be transported directly to the collapse site. To address this issue, in this embodiment, the frame 1 is a detachable three-section structure. Specifically, as shown... Figures 1-6As shown, the frame 1 consists of a front frame section 101, a middle frame section 102, and a rear frame section 103 from front to back. The front end of the middle frame section 102 is connected to the front frame section 101, and the rear end is connected to the rear frame section 103. Specifically, the front end of the middle frame section 102 is connected to the front frame section 101 via a detachable connection structure, and the rear end is connected to the rear frame section 103 via a detachable connection structure. The so-called detachable connection structure refers to a detachable connection structure, which allows the middle frame section 102 to be separated or connected from the front frame section 101, and also to be separated or connected from the rear frame section 103, by disassembling and assembling the detachable connection structure.

[0038] To allow the outer sleeve drive 6 and the inner spiral shaft drive 7 to move forward and backward with a large stroke, translational guide structures for their forward and backward movement are distributed on the front frame section 101 and the middle frame section 102. In other words, the front and middle frame sections 102 are equipped with translational guide structures that can be connected sequentially in the front and middle frame sections 102 to allow the drilling rig's inner spiral shaft drive 7 and outer sleeve drive 6 to move forward and backward normally.

[0039] The pipe clamping device 4 is installed on the front frame section 101. In other words, the front frame section 101 is provided with a pipe clamping device mounting base 105 for installing the pipe clamping device 4.

[0040] The tracked walking mechanism 2 is connected to the middle frame section 102. In other words, the middle frame section 102 is provided with a track mounting base 106 for connecting the tracked walking mechanism 2.

[0041] The auxiliary equipment is installed on the rear frame section 103. In other words, the rear frame section 103 is equipped with an auxiliary equipment mounting base for installing the auxiliary equipment of the drilling rig.

[0042] In general, the drilling rig in this embodiment can be divided into three parts. During rescue operations, the three parts can be transported to the site separately according to the on-site transportation conditions. After arriving at the site, the three-section frame 1 is connected and assembled to form a complete rescue drilling rig, thereby achieving the effect of rapid transportation and assembly and saving rescue time.

[0043] To enhance the connection strength of each section of the frame 1, in a preferred embodiment, the detachable connection structure between the middle frame section 102 and the front frame section 101 includes two connecting plates located on the middle frame section 102 and the front frame section 101, respectively. For ease of description, the connecting plate on the front frame section 101 can be defined as the first connecting plate 1011, and the connecting plate at the front end of the middle frame 1 can be defined as the second connecting plate 1021. Figures 4-6 As shown, the front frame section 101 and the middle frame section 102 are connected by the cooperation of the first connecting plate 1011 and the second connecting plate 1021.

[0044] A protrusion 1012 is provided on the first connecting plate 1011, and an insertion hole 1022 is provided on the second connecting plate 1021. The insertion hole 1022 allows the protrusion 1012 to be inserted. This formed stop structure, or insertion structure, allows the front frame section 101 and the middle frame section 102 to be directly connected, improving the connection strength between the front frame section 101 and the middle frame section 102. It is understood that the positions of the protrusion 1012 and the insertion hole 1022 can be interchanged. Specifically, in other embodiments, the protrusion 1012 can be provided on the second connecting plate 1021, and the insertion hole 1022 can be provided on the first connecting plate 1011.

[0045] Meanwhile, the first connecting plate 1011 and the second connecting plate 1021 are also connected by detachable fasteners. The detachable fasteners can be connecting bolts 108 as shown in the figure. Multiple sets of connecting bolts 108 can be provided, and there are six sets in the figure. Six sets of coaxial bolt holes 1023 are provided on the first connecting plate 1011 and the second connecting plate 1021. Of course, in other embodiments, the fasteners can also be pins.

[0046] Similarly, the middle frame section 102 and the rear frame section 103 can also be connected using the same detachable connection structure. Specifically, connecting plates are provided on the rear end of the middle frame section 102 and the rear frame section 103, respectively. For ease of description, the connecting plate at the rear end of the middle frame section 102 can be defined as the third connecting plate, and the connecting plate on the rear frame section 103 can be defined as the fourth connecting plate. The protrusion 1012 and the insertion hole 1022 structure and the fastener setting method provided on the third connecting plate and the fourth connecting plate can be the same as those of the first connecting plate 1011 and the second connecting plate 1021, and will not be described in detail here.

[0047] More preferably, in some implementations, such as Figure 5 As shown, the second connecting plate 1021 is also provided with a pipeline through hole 1024 for pipelines to pass through, such as hydraulic lines and electrical wiring harnesses of the drilling rig. Of course, not shown in the figure, pipeline through holes 1024 are also provided on the first connecting plate 1011, the third connecting plate and the fourth connecting plate.

[0048] The above examples illustrate a preferred detachable connection structure. In other embodiments, the front frame section 101 and the middle frame section 102 can also be connected by flanges and bolts.

[0049] In a preferred embodiment, each functional device is connected or installed at a corresponding position on the frame 1 via a detachable connection structure. Specifically, the tracked walking mechanism 2 is connected to the middle frame section 102 via a detachable connection structure, the pipe clamping device 4 is installed on the front frame section 101 via a detachable connection structure, and the required auxiliary equipment is installed on the rear frame section 103 via a detachable connection structure. This allows the drilling rig to be further disassembled according to on-site transportation conditions, and assembled on-site after each part is transported to its destination, further improving the drilling rig's mobility.

[0050] Considering that some tunnels (tunnels) have tracks laid at the bottom, in some implementation methods, such as Figure 10 As shown, the tracked walking mechanism 2 can be switched to a wheeled (steel wheel) walking mechanism. Specifically, the wheeled walking mechanism includes a front walking wheel set 13 and a rear walking wheel set 14. A front wheel set mounting position for the front walking wheel set 13 is provided on the front frame section 101, and a rear wheel set mounting position for the rear walking wheel set 14 is provided on the middle frame section 102. The front walking wheel set 13 and the rear walking wheel set 14 can be detachably installed on the front frame section 101 and the middle frame section 102 respectively via a detachable connection structure. For road conditions with paved tracks, the tracked walking mechanism 2 can be removed and replaced with the walking wheel set. For uneven conditions, the walking wheel set can be removed and replaced with the tracked walking mechanism 2. Installing the front walking wheel set 13 on the front frame section 101 ensures a large span between the front walking wheel set 13 and the rear walking wheel set 14, guaranteeing the stability of the drilling rig.

[0051] In some embodiments, the auxiliary equipment on the rear frame section 103 includes a folding boom crane 8, which is used to lift the outer sleeve 3 and the inner helical shaft 5. Specifically, it includes a robotic arm and a hoist at the output end of the robotic arm, which is also prior art. A turntable 104 is provided on the rear frame section 103. The structure of the turntable 104 is prior art, specifically including a drive motor (or hydraulic motor) and a slewing bearing. The axis of the turntable 104 extends vertically, and the turntable 104 constitutes a crane mounting base for mounting the folding boom crane 8. Mounting the folding boom crane 8 on the turntable 104 allows for its rotational swing. Specifically, to facilitate the assembly and disassembly of the folding boom crane 8, a flange can be provided at the bottom end of the folding boom crane 8 to fix it to the turntable 104.

[0052] In some implementations, auxiliary equipment on the rear frame section 103 includes an engine 9, which provides power to the drilling rig. The engine 9 is also detachable. For coal mine roadways, which are typically equipped with electrically driven flatbed trucks, it is unnecessary to equip the drilling rig with the engine 9 (see reference). Figure 10 ).

[0053] In some embodiments, the auxiliary equipment includes a rear support 10 (rearing device), which can be grounded to provide support reaction force for the drilling rig. Specifically, such as Figure 2 and Figure 3 As shown, the rear support 10 includes a left support column 1002 and a right support column 1005 respectively hinged to the left and right sides of the rear frame section 103. Both the left support column 1002 and the right support column 1005 can be hinged to the rear frame section 103 via quick-release pins. The lower ends of the left support column 1002 and the right support column 1005 are provided with ground support structures 1003 for ground support. Specifically, the ground support structure 1003 can be a ground support beam connecting the left support column 1002 and the right support column 1005, or it can be a ground support plate respectively connected to the left support column 1002 and the right support column 1005; there is no specific limitation here. A left telescopic sleeve 1001 is connected between the left support column 1002 and the rear frame section 103. Specifically, both ends of the left telescopic sleeve 1001 can be hinged to the left support column 1002 and the rear frame section 103 via quick-release pins. Correspondingly, a right telescopic sleeve is connected between the right support column 1005 and the rear frame section 103. The two ends of the right telescopic sleeve can be hinged to the right support column 1005 and the frame section 1 respectively via quick-release pins.

[0054] The left support column 1002, the left telescopic sleeve 1001, and the rear frame section 103 form a triangular support structure, as do the right support column 1005, the right telescopic sleeve, and the rear frame section 103. As telescopic sleeves, both the left and right telescopic sleeves include an outer cylinder and an inner cylinder, with the inner cylinder extending and retracting along the outer cylinder. During rescue operations, adjusting the left and right telescopic sleeves 1001 and 1005 can respectively cause the left and right support columns 1002 and 1005 to swing up and down, allowing the ground support structure 1003 to adaptably support ground at different heights.

[0055] To improve support stability, after the ground support structure 1003 supports the ground, a pin 1004 can be driven into the ground through the ground support structure 1003.

[0056] Of course, as a stable support structure, the telescopic sleeve should have a locking position with a constant length, i.e., a mechanical locking position. To adapt to ground heights of different levels, at least two mechanical locking positions should be provided, spaced apart along the telescopic sleeve's extension direction. Mechanical locking devices can be used to lock the (left and right) telescopic sleeves in a defined locking position. Specifically, Figure 2 The example provided is a case in which the left telescopic sleeve 1001 is provided with three mechanical locking positions. The mechanical locking component can be a pin. The left telescopic sleeve 1001 is provided with three pin holes, and the positions of the three pin holes correspond to the three mechanical locking positions respectively. Inserting the pin can lock the left telescopic sleeve 1001 in the determined locking position.

[0057] Unlike conventional rear supports 10, firstly, the rear support 10 has a triangular support structure. The ground support structure 1003 swings with the left support column 1002 and the right support column 1005, ensuring that the ground support structure 1003 has a large ground support area for different ground heights, thereby reducing the ground pressure. Secondly, the telescopic sleeve is mechanically locked. Compared with hydraulic cylinder locking, the mechanical locking structure is more reliable and less expensive.

[0058] It should be noted that the auxiliary equipment is not limited to the types mentioned above. In some embodiments, the rear support 10 can be omitted, such as... Figure 11 As shown, if there is a stable foundation in front of the drilling rig, anchor points 15 can be driven into the foundation in front of the drilling rig, and the anchor points 15 can be connected to the drilling rig by a chain hoist 16, so as to use the chain hoist 16 to pull and maintain the stability of the drilling rig. In some embodiments, if there is a rail hoisting system (monorail) at the top of the tunnel (tunnel) or a small gantry crane is available on site, then the folding boom crane 8 on the rear frame section 103 can also be omitted.

[0059] In addition, to ensure the stability of the drilling rig during construction, hydraulic outriggers 107 can be installed on the front frame section 101 and the rear frame section 103.

[0060] As a preferred implementation method, such as Figure 8 and Figure 9 As shown, the tube clamping device 4 includes a base 401, on which a central channel is provided for the outer tube 3 to pass through from front to back. The base 401 is provided with a tube clamping mechanism 405 and a centering support mechanism. The tube clamping mechanism 405 is used to clamp the outer tube 3 when connecting the outer tube 3. Specifically, it includes a tube clamping cylinder and a clamp driven by the tube clamping cylinder. The clamping surface of the clamp matches the outer tube 3.

[0061] The centering support mechanism includes four (sets) of centering components 402 arranged in a predetermined orientation along the circumference of the central channel. Specifically, the four centering components 402 can be distributed in an "X" shape. Each centering component 402 includes an adjusting rod 403, one end of which is connected to the base 401, and the other end is provided with a rolling support 406. The rolling support 406 is used to (roll) support the outer sleeve 3 passing through the central channel. The adjusting rod 403 can be adjusted and moved radially relative to the base 401 along the outer sleeve 3, so as to determine the axial position of the outer sleeve 3 by adjusting the movement of different centering components 402 relative to the base 401.

[0062] In this preferred embodiment, the four centering components 402 can individually adjust the position of the rolling support 406 to more flexibly limit or determine the center of the outer sleeve, prevent the head-down phenomenon, and ensure the drilling posture of the outer sleeve.

[0063] Based on the three-point centering principle, in other embodiments, the centering component 402 can be set with at least three (groups). Of course, in some embodiments, the centering component 402 can also be set with five (groups) or even more.

[0064] Furthermore, one end of the adjusting rod 403 is provided with an external thread and passes through the seat 401. The seat 401 is provided with a fixing nut 404, and the adjusting rod is threadedly connected to the fixing nut 404 so that the radial adjustment movement of the adjusting rod can be achieved by turning the adjusting rod. In other words, the adjusting rod and the fixing nut 404 constitute a screw-nut mechanism, which can realize stepless adjustment of the radial position of the rolling support 406, and this structure is relatively simple and reliable.

[0065] The rolling support 406 can be a rolling bearing or a roller, and a wheel frame 407 can be connected to the adjusting rod accordingly. The rolling support 406 can rotate around a fixed axis, with its axis extending in the front-to-back direction.

[0066] It should be noted that in other embodiments, the adjusting rod 403 can be directly adopted as a hydraulic cylinder, so as to realize the radial position adjustment of the rolling support 406 by extending and retracting the piston rod of the hydraulic cylinder.

[0067] In some preferred embodiments, such as Figure 2 and Figure 3 As shown, a recessed pipe clamping device mounting base 105 is provided at the front end of the front frame section 101, and the pipe clamping device 4 is mounted on this pipe clamping device mounting base 105. The term "recessed structure" means that the structure is recessed relative to the main body of the front frame section 101, which reduces the height of the pipe clamping device 4 and ensures that the bottom of the pipe clamping device 4 has a more stable support structure.

[0068] Specific embodiments of the modular rack provided by this invention: The modular frame is the same frame described in the above-described implementation of the mobile rescue drilling rig, and will not be further explained here.

[0069] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
