Description

Technical Field

[0001] This invention relates to the field of tunnel rescue equipment technology, and in particular to a rescue equipment and method capable of flexible construction and rescue. Background Technology

[0002] Currently, after a collapse, rescue methods mainly include pre-installing pipelines inside the tunnel, manually excavating pilot tunnels (within the collapsed area or around the collapse site), and using mechanical construction to create escape routes. However, these methods currently have the following problems:

[0003] 1. Manual excavation of pilot tunnels for rescue and support is time-consuming, slow, and prone to causing secondary injuries to rescuers; mechanical construction of escape tunnels is not well adapted to deep burial conditions, and the rescue angle is mostly horizontal / vertical. In cases where there are obstacles on straight routes, it is difficult to select the best route and delay rescue time.

[0004] 2. Existing curved rescue equipment has poor flexibility and often requires hard conditions such as ground hardening and the construction of a starting platform, which can easily delay rescue time; moreover, the pipe sections of the curved rescue method are mostly whole loop pipe sections, which require frequent disconnection of the pipeline during assembly, and the pipeline reconnection takes a long time, resulting in slow rescue speed.

[0005] Therefore, improving the applicability of rescue equipment and achieving rapid, safe, and efficient emergency rescue are urgent problems that need to be solved. Summary of the Invention

[0006] The purpose of this invention is to provide a rescue device and a rescue method that solves the problems of poor flexibility and low efficiency of existing rescue devices, thereby achieving rapid response and safe and efficient emergency rescue.

[0007] The above-mentioned technical objectives of the present invention are mainly achieved through the following technical means:

[0008] On one hand, the present invention provides a rescue device, which includes:

[0009] It can be used as a transportation device for ground tunneling platforms, and the transportation device can flexibly transfer various equipment carried to the starting position;

[0010] An angle-adjustable launching device is connected to the transport device, the launching device having a curvature adjustment mechanism;

[0011] The tunneling device is driven and connected to the launching device. The tunneling device has a tunneling host and a rescue pipe connected to the tunneling host. The rescue pipe passes through the curvature adjustment mechanism and can tunnel along a predetermined rescue route under the drive of the launching device. The curvature adjustment mechanism can adapt to the curvature of the rescue pipe in the length direction.

[0012] After the tunneling device reaches the rescue point, a rescue device is installed in the rescue pipeline that can be walked on, and the rescue device can transport the trapped personnel out along the rescue pipeline.

[0013] The rescue equipment described in this invention can fully utilize the flexibility of the transportation device to achieve a rapid response to emergency rescue, eliminating the need for the construction of a ground tunneling platform and buying valuable rescue time for trapped personnel.

[0014] The rescue equipment described in this invention is equipped with an angle-adjustable launching device, which enables multi-angle and multi-curvature tunneling by adjusting the launching angle. It is also compatible with vertical / horizontal and special angle tunneling methods, expanding the range of tunneling route selection and allowing for the selection of a more suitable rescue route based on the actual accident scenario.

[0015] The rescue equipment described in this invention utilizes a small curved tunneling machine (tunneling host) to quickly excavate and open up a safe passage, accurately reaching the rescue location, shortening the rescue time, and maximizing the chances of finding and rescuing trapped personnel.

[0016] The rescue equipment described in this invention is simple in structure and easy to operate. It can quickly realize rescue response, accurately, rapidly, and in multiple ways open life channels for rescue. It can be widely used for rescue of collapse accidents during underground space construction and use, and can also be used for rescue of collapse accidents in underground caverns such as underground coal mines, highway tunnels, and culverts.

[0017] In a preferred embodiment of the present invention, the launching device includes a support frame, one side of the bottom of the support frame is connected to the transport device via a hinge seat, the curvature adjustment mechanism is disposed inside the support frame, and a pipeline transport channel is formed inside the support frame.

[0018] In this embodiment, the support frame is the main load-bearing frame of the launching device, which can ensure the stability of the equipment when providing reaction force during the downward excavation of the rescue pipeline, and at the same time protect the transportation of the rescue equipment and the rescue pipeline.

[0019] In a preferred embodiment of the present invention, the curvature adjustment mechanism includes a plurality of pipe clamps spaced apart along the extension direction of the pipeline delivery channel. The pipe clamps are sleeved on the circumferential outer side of the rescue pipeline, and a curvature adjuster is provided between each pipe clamp and the support frame to adjust the size and position of the pipe clamp.

[0020] In this embodiment, the diameter and inclination angle of the pipe clamp can be adjusted according to the outer diameter and curvature of the rescue pipe to meet the adjustment requirements under different outer diameter and curvature conditions.

[0021] In a preferred embodiment of the present invention, the support frame is further provided with a jacking mechanism, the jacking mechanism including a jacking cylinder provided in the support frame, and a pipe clamp connected to the hydraulic rod of the jacking cylinder, the pipe clamp being sleeved on the outside of the rescue pipe.

[0022] In this embodiment, the jacking mechanism provides power for the tunneling machine to move forward. The jacking mechanism acts on the pipe clamp through the hydraulic rod of the jacking cylinder. The pipe clamp acts on the rescue pipe through the reaction force provided by friction, and under the action of the jacking force, it drives the tunneling machine and the rescue pipe to move forward.

[0023] In a preferred embodiment of the present invention, an angle-adjustable working platform is provided on the outer side of the support frame. The working platform includes an operating plate connected to the support frame and a telescopic rod connected between the operating plate and the support frame. The telescopic rod can extend and retract with the tilt of the support frame so that the operating plate is always in a working state with the same angle (usually a horizontal state).

[0024] In this embodiment, the angle of the control panel can adapt to the different tunneling requirements of the launching device, meeting the operational needs under various working conditions.

[0025] In a preferred embodiment of the present invention, the bottom of the support frame is detachably connected to a base, one side of the base is connected to the transport device, and the other side of the base is connected to the support frame with an angle adjustment rod for adjusting the angle of the support frame.

[0026] In this embodiment, the angle adjustment rod can adjust the angle of the support frame, that is, it can adjust the starting angle of the launching device to adapt to different rescue routes.

[0027] In a preferred embodiment of the present invention, the rescue pipeline includes a plurality of pipe sections connected in sequence, and the shape of the rescue pipeline is the same as the shape of the predetermined rescue route along the length direction of the rescue pipeline.

[0028] In this embodiment, the rescue pipeline is spliced ​​together section by section, which facilitates the lowering of the pipeline during the downward excavation process and avoids the need to limit the entire rescue pipeline at the beginning of the excavation. At the same time, the shape of the rescue pipeline is the same as the shape of the rescue route, so that the rescue pipeline will not generate bending stress during the curved rescue process, thereby avoiding deviation of the excavation route.

[0029] In a preferred embodiment of the invention, each of the tube sections comprises at least two mating segments.

[0030] In this embodiment, each pipe segment on the rescue pipeline adopts a splicing structure. When it is necessary to add pipe segments one by one during downward excavation, multiple pipe segments can be directly placed on the pipeline connected to the tunneling machine, and then spliced ​​to form the corresponding pipe segment. That is, there is no need to cut the pipeline on the tunneling machine during the process of adding pipe segments one by one, thereby simplifying the splicing operation between adjacent pipe segments.

[0031] In a preferred embodiment of the present invention, the rescue pipe is provided with a guide rail for sliding connection of the rescue device, and the guide rail extends along the length direction of the rescue pipe.

[0032] In this embodiment, the guide rail installed inside the rescue pipeline can guide the rescue device to slide inside the rescue pipeline, preventing it from rotating in the circumferential direction of the rescue pipeline during the sliding process, thereby affecting the safety of the trapped personnel inside the rescue device; at the same time, the installation of the guide rail also enables the rescue device to be quickly lowered to the rescue point, preventing it from getting stuck inside the rescue pipeline during the lowering or lifting process.

[0033] In a preferred embodiment of the present invention, the guide rail is provided as a connector at the abutment position of two adjacent segments. One side of the guide rail is welded to one of the segments, and the other side of the guide rail is bolted to the other segment. The guide rail has a threaded hole on the side facing the segment, and the connecting bolt passes through the bolt hole on the segment from the outside of the segment and is threadedly connected to the threaded hole.

[0034] In this embodiment, the diameter of the rescue pipe is relatively small, making it easier and safer to screw the connecting bolts in from the outside. The connecting bolts can be screwed in first and then pushed in, which provides more working space compared to connecting inside the rescue pipe.

[0035] In a preferred embodiment of the present invention, each of the pipe sections includes a first pipe segment and a second pipe segment that are fitted together. Each of the pipe sections is provided with a guide rail for sliding connection of the rescue device. The fitted first pipe segment and the second pipe segment form a first joint and a second joint. The guide rail is located at the first joint. One side of the guide rail is welded to the first pipe segment, and the other side of the guide rail is bolted to the second pipe segment.

[0036] In this embodiment, the guide rail is set at the first joint of the first and second segments, and the guide rail is used as a connector at the first joint. This simplifies the connection operation at the first joint and also improves the structural strength at the first joint.

[0037] In a preferred embodiment of the present invention, an I-beam connector is provided at the second butt joint. The I-beam connector has two opposing positioning plates and a clamping plate connected between the two positioning plates. The clamping plate is located inside the second butt joint. One of the positioning plates is attached to the outer side of the first and second pipe segments, and the other positioning plate is attached to the inner side of the first and second pipe segments. A bolt passes through the two positioning plates.

[0038] In this embodiment, the first and second segments are connected at the second joint using an I-beam connector. Compared to relatively conventional connection methods such as welding, the I-beam connector can provide better connection strength, ensuring that the spliced ​​pipe section does not crack or deform in the high-pressure underground environment.

[0039] In a preferred embodiment of the present invention, the first segment has a first snap-fit ​​groove and a first snap-fit ​​block at the second joint, and the second segment has a second snap-fit ​​groove and a second snap-fit ​​block at the second joint, wherein the first snap-fit ​​block is engaged in the second snap-fit ​​groove and the second snap-fit ​​block is engaged in the first snap-fit ​​groove.

[0040] In this embodiment, another segment connection structure is provided, in which the first segment and the second segment are interlocked together at the second joint by means of a snap-fit ​​groove and a snap-fit ​​block, thereby forming a relatively locked structure, ensuring that the pipe section formed by splicing the segments has high structural strength.

[0041] In this embodiment, the water-stop strip can enhance the waterproofness of the rescue pipeline, preventing groundwater from entering the rescue pipeline and thus preventing the rescue operation from proceeding smoothly.

[0042] In a preferred embodiment of the present invention, the adjacent pipe sections are connected by threads, and the tightening direction of the threads is the same as the rotation direction of the tunneling machine.

[0043] In this embodiment, adjacent pipe sections are connected by bolts, which facilitates the connection and disassembly of the rescue pipeline and allows the rescue pipeline to be reused; the setting of the thread direction can prevent the adjacent pipe sections from loosening during the rotation of the tunneling machine.

[0044] In a preferred embodiment of the present invention, the tunneling machine is connected to a pipeline bundle located in the rescue pipeline. Each pipeline in the pipeline bundle is provided with a disconnection mechanism between itself and the tunneling machine. The pipeline bundle can be disconnected from the tunneling machine through the disconnection mechanism after the tunneling device has tunneled to the rescue point, and can be pulled out from the rescue pipeline.

[0045] In this embodiment, to increase the rescue rate, it is necessary to control the diameter of the rescue pipeline as much as possible and reduce the amount of excavation. After the tunneling machine completes the tunneling operation, in order to leave sufficient escape space for the trapped personnel, it is necessary to clean up the pipeline bundles and debris inside the pipeline. Therefore, a disconnection mechanism is provided, which can disconnect the pipeline bundles from the tunneling machine after the tunneling is completed, so as to facilitate the pulling of the pipeline bundles out of the rescue pipeline, make enough space for the installation of the rescue device, and avoid the presence of the pipeline bundles affecting the movement of the rescue device.

[0046] In a preferred embodiment of the present invention, the disconnection mechanism includes a sleeve and a lock cylinder that are engaged with each other. The lock cylinder is located inside the sleeve. The inner sidewall of the sleeve is provided with a plurality of locking tongues that can extend and retract in the radial direction of the sleeve. The outer sidewall of the lock cylinder is provided with a plurality of locking grooves that engage with the locking tongues. When the tunneling device tunnels to the rescue point, the locking tongues can retract radially outward to separate the sleeve and the lock cylinder. The sleeve is connected to the tunneling host, and the lock cylinder is connected to the end of the pipeline. Alternatively, the lock cylinder is connected to the tunneling host, and the sleeve is connected to the end of the pipeline.

[0047] In this embodiment, the disconnection mechanism adopts a sleeve and lock core structure that can automatically interlock and disconnect, which can quickly realize the connection and disconnection operations between the pipeline and the tunneling host.

[0048] In a preferred embodiment of the present invention, an electromagnetic suction seat is provided between the plurality of locking tongues and the inner sidewall of the sleeve, and a spring is provided between the electromagnetic suction seat and the locking tongue. The locking tongue is made of magnetic material. When the electromagnetic suction seat is de-energized, the locking tongue extends radially inward under the action of the spring and is engaged in the latching groove. When the electromagnetic suction seat is energized, the locking tongue retracts radially outward under the action of electromagnetic force and disengages from the latching groove.

[0049] In this embodiment, a combination of an electromagnetic chuck and a spring is used to control the extension and retraction of the locking tongue, thereby enabling the connection and disconnection of pipelines. The control method is simple and easy for operators on the ground to perform.

[0050] In a preferred embodiment of the present invention, the sleeve is provided with a connecting pipe that can mate with the lock cylinder, the connecting pipe is connected to the tunneling host, and a sealing ring is provided between the connecting pipe and the lock cylinder.

[0051] In this embodiment, the docking cylinder can serve as an intermediary between the lock cylinder and the tunneling host, thereby enabling the connection between the rescue pipeline and the tunneling host. The sealing ring can prevent leakage at the docking position of the lock cylinder.

[0052] In a preferred embodiment of the present invention, an openable rescue door is provided on the side wall of the end of the rescue pipeline connected to the tunneling machine.

[0053] In this embodiment, the rescue door facilitates the entry of trapped personnel into the rescue device inside the rescue pipeline.

[0054] In a preferred embodiment of the present invention, the rescue device includes a lying board for accommodating the trapped person and a main roller assembly and an auxiliary roller assembly disposed on the outer side wall of the lying board. The main roller assembly is in rolling cooperation with the guide rail, and the auxiliary roller assembly is in rolling cooperation with the rescue pipe. A set of the auxiliary roller assembly is respectively provided on both sides of the main roller assembly.

[0055] In this embodiment, the reclining board allows trapped personnel to lie down, and the main roller assembly, which rolls in conjunction with the guide rail, ensures that the reclining board moves along a predetermined route without deviating. The auxiliary roller assembly allows the rescue device to be effectively transported within the arched section of the rescue pipeline, providing lateral support for the reclining board and real-time correction of the rescue device.

[0056] In a preferred embodiment of the present invention, the main roller assembly includes two main rollers located on both sides of the guide rail, and the two main rollers can roll on the two side walls of the guide rail respectively.

[0057] In this embodiment, the tops of the two main rollers are tangent to the outer side of the guide rail, which can provide lateral guidance when the rescue device moves and provide guiding force when making curvature turns.

[0058] In a preferred embodiment of the present invention, the main roller assembly includes a plurality of main rollers spaced apart along the length direction of the lying board, and the auxiliary roller assembly includes a plurality of auxiliary rollers spaced apart along the length direction of the lying board.

[0059] In this embodiment, multiple main rollers and multiple auxiliary rollers are provided to give the slab multiple support points, ensuring its stability during movement.

[0060] In a preferred embodiment of the present invention, a cable is connected to one end of the deck away from the tunneling machine, and the other end of the cable extends along the length of the rescue pipeline and is connected to a traction mechanism on the ground.

[0061] In this embodiment, the traction mechanism connected to the other end of the cable can control the lowering or raising of the deck.

[0062] In a preferred embodiment of the present invention, an upper guard plate and a lower guard plate are respectively connected to the upper and lower ends of the reclining board, a foot buckle is provided on the lower guard plate, handrails are provided on both sides of the reclining board, and a safety belt is provided inside the reclining board.

[0063] In this embodiment, the upper and lower guard plates can ensure that the trapped personnel are not entangled or scratched by pipelines, slag, or other debris inside the pipe during the rescue of the trapped personnel; the lower guard plate is used to support the weight of the trapped personnel and is equipped with a safety belt and foot buckle to secure the trapped personnel's body. At the same time, the trapped personnel can use the handrail to correct their posture and avoid secondary injuries during the rescue.

[0064] In a preferred embodiment of the present invention, the launching device includes a support frame, one side of the bottom of the support frame is connected to the transport device via a hinge seat, the curvature adjustment mechanism is disposed inside the support frame, and a pipeline transport channel is formed inside the support frame.

[0065] In this embodiment, the support frame is the main load-bearing frame of the launching device, which can ensure the stability of the equipment when providing reaction force during the downward excavation of the rescue pipeline, and at the same time protect the transportation of the rescue equipment and the rescue pipeline.

[0066] In a preferred embodiment of the present invention, the curvature adjustment mechanism includes a plurality of pipe clamps spaced apart along the extension direction of the pipeline delivery channel. The pipe clamps are sleeved on the circumferential outer side of the rescue pipeline, and a curvature adjuster is provided between each pipe clamp and the support frame to adjust the size and position of the pipe clamp.

[0067] In this embodiment, the diameter and inclination angle of the pipe clamp can be adjusted according to the outer diameter and curvature of the rescue pipe to meet the adjustment requirements under different outer diameter and curvature conditions.

[0068] In a preferred embodiment of the present invention, the support frame is further provided with a jacking mechanism, the jacking mechanism including a jacking cylinder provided in the support frame, and a pipe clamp connected to the hydraulic rod of the jacking cylinder, the pipe clamp being sleeved on the outside of the rescue pipe.

[0069] In this embodiment, the jacking mechanism provides power for the tunneling machine to move forward. The jacking mechanism acts on the pipe clamp through the hydraulic rod of the jacking cylinder. The pipe clamp acts on the rescue pipe through the reaction force provided by friction, and under the action of the jacking force, it drives the tunneling machine and the rescue pipe to move forward.

[0070] In a preferred embodiment of the present invention, an angle-adjustable working platform is provided on the outer side of the support frame. The working platform includes an operating plate connected to the support frame and a telescopic rod connected between the operating plate and the support frame. The telescopic rod can extend and retract as the support frame tilts so that the operating plate is always in a horizontal state.

[0071] In this embodiment, the angle of the control panel can adapt to the different tunneling requirements of the launching device, meeting the operational needs under various working conditions.

[0113] Implementation

[0114] like Figure 1 and Figure 2As shown, the present invention provides a rescue device, which includes: a transport device 10 that can serve as a ground tunneling platform, capable of flexibly transferring various equipment to a starting position 60; a starting device 20 connected to the transport device 10 at an adjustable angle, the starting device 20 having a curvature adjustment mechanism 21; a tunneling device 30 drivenly connected to the starting device 20, the tunneling device 30 having a tunneling host 31 and a rescue pipeline 32 connected to the tunneling host 31, the rescue pipeline 32 passing through the curvature adjustment mechanism 21 and capable of tunneling along a predetermined rescue route 61 under the drive of the starting device 20, the curvature adjustment mechanism 21 being adaptable to the curvature in the length direction of the rescue pipeline 32; and a rescue device 40 that is walkable within the rescue pipeline 32 after the tunneling device 30 has reached the rescue point 62, the rescue device 40 being capable of transporting the trapped personnel 63 out along the rescue pipeline 32.

[0115] The rescue equipment described in this invention can fully utilize the flexibility of the transport device 10 to achieve a rapid response to emergency rescue, eliminating the need for the construction of a ground tunneling platform and buying valuable rescue time for the trapped personnel 63.

[0116] The rescue equipment described in this invention is equipped with an angle-adjustable launching device 20. By adjusting the launching angle, it can achieve multi-angle and multi-curvature tunneling, expanding the range of tunneling route selection. It can select a more suitable rescue route 61 according to the actual accident scenario.

[0117] The rescue equipment described in this invention utilizes a small curved tunneling machine (tunneling host 31) to quickly tunnel open a safe passage, accurately reaching the rescue point 62, shortening the rescue time, and maximizing the chances of finding and rescuing the trapped personnel 63.

[0118] The rescue equipment described in this invention is simple in structure and easy to operate. It can quickly realize rescue response and can accurately, rapidly, and in multiple ways open life channels to carry out rescue. It can be widely used for rescue of collapse accidents during underground space construction and use, and can also be used for rescue of collapse accidents in underground caverns such as underground coal mines, highway tunnels, and culverts.

[0119] The following will describe in detail the specific structure of each part of the rescue equipment described in this invention, the position and connection relationship between each part, and the preferred embodiment of each part.

[0120] like Figure 1 and Figure 2As shown, the rescue equipment of the present invention includes a transport device 10, which is a flexible transfer platform. It can be equipped with conventional vehicles, tracked vehicles, etc. It carries various rescue equipment. After receiving the distress call from the trapped person 63, the rescuers can drive the transport device 10 to the accident site quickly and can directly use the transport device 10 as a tunneling platform without having to build a separate tunneling platform.

[0121] Specifically, such as Figure 1 As shown, multiple wheels 11 are connected to the reinforced steel beam 13 of the transport device 10. When carrying out rescue operations in areas with good ground conditions, the tracks 12 can be omitted, and the vehicle can be driven directly by the wheels 11, ensuring that the transport device 10 can move at a faster speed and respond to rescue needs more quickly.

[0122] Furthermore, when conducting rescue operations in areas with poor ground conditions, tracks 12 can be added to improve the adaptability of the transport device 10, ensuring that it can smoothly pass through complex geological surfaces and avoid breakdowns that delay rescue opportunities. Adding tracks 12 enables it to adapt to various complex and harsh road conditions, ensuring that rescue equipment can respond quickly and arrive on time in various adverse environments.

[0123] like Figure 1 As shown, the rescue equipment of the present invention also includes a launching device 20, which is the core device of the rescue equipment. It is connected to the transport device 10 and can move with the transport device 10 to the accident location. The angle of the launching device 20 relative to the horizontal plane can be adjusted. After the rescue route 61 and the launching position 60 are determined at the accident location, the transport device 10 is moved to move the launching device 20 to the launching position 60. At the same time, the inclination angle of the launching device 20 is adjusted according to the launching angle required by the rescue route 61 to ensure that the tunneling device 30 can tunnel downward along the predetermined rescue route 61 after it is launched.

[0124] The launching device 20 is equipped with a curvature adjustment mechanism 21, through which the rescue pipe 32 in the rescue device 40 can pass. When the predetermined rescue route 61 is curved, the selected corresponding rescue pipe 32 is also curved. The curvature adjustment mechanism 21 can adapt to the curvature of the rescue pipe 32 at different positions. The position of the curvature adjustment mechanism 21 is adaptively adjusted according to the curvature of a section of the rescue pipe 32 located in the launching device 20, so that the rescue pipe 32 will not generate offset stress in the launching device 20, thereby causing the tunneling direction of the tunneling host 31 to deviate.

[0125] According to one embodiment of the present invention, such as Figures 1 to 3As shown, the launching device 20 includes a support frame 22. One side of the bottom of the support frame 22 is connected to the transport device 10 via a hinge seat. A curvature adjustment mechanism 21 is disposed within the support frame 22, and a pipeline transport channel 224 is formed within the support frame 22. The support frame 22 is the main load-bearing frame of the launching device 20, which can ensure the stability of the equipment when providing reaction force during the downward excavation of the rescue pipeline 32, and also protect the transport of the rescue equipment and the rescue pipeline 32.

[0126] Specifically, such as Figure 3 As shown, the support frame 22 is a cuboid frame composed of horizontal trusses 221 and vertical trusses 222. An internal support truss 223 is installed inside the support frame 22 to improve its structural strength. A pipeline transport channel 224 extending along the length of the support frame 22 is formed inside the support frame 22. During downward tunneling and rescue operations, some of the rescue pipelines 32 on the ground are located within this pipeline transport channel 224. Each truss is composed of multiple steel components connected by welding or bolting. The entire frame serves as the main load-bearing component during tunneling. The support frame 22 is a conventional cuboid truss structure, and its specific structure will not be further described here.

[0127] One side of the bottom of the support frame 22 is rotatably connected to the rear end of the reinforcing steel beam 13 of the transport device 10. In this embodiment, the support frame 22 and the transport device 10 are rotatably connected by a hinge seat.

[0128] According to one embodiment of the present invention, such as Figures 1 to 3 As shown, the curvature adjustment mechanism 21 includes multiple pipe clamps 211 spaced apart along the extension direction of the pipeline transport channel 224. The pipe clamps 211 are fitted around the circumferential outer side of the rescue pipeline 32. Each pipe clamp 211 is connected to the support frame 22 by a curvature adjuster 212 capable of adjusting the size and position of the pipe clamp 211. The diameter and inclination angle of the pipe clamps 211 can be adjusted according to the outer diameter and curvature of the rescue pipeline 32 to meet adjustment requirements under different outer diameter and curvature conditions.

[0129] Specifically, such as Figure 2 and Figure 3 As shown, the pipe clamp 211 is a circular component, which is fitted around the rescue pipe 32. A certain gap is maintained between the pipe clamp 211 and the rescue pipe 32. Multiple pipe clamps 211 are provided along the extension direction of the pipeline conveying channel 224, and each pipe clamp 211 is fitted around the circumferential outer side of the rescue pipe 32.

[0130] In this embodiment, as Figure 3As shown, the curvature adjustment mechanism 21 includes three pipe clamps 211 spaced apart. Each pipe clamp 211 is connected to the support frame 22 on both sides by a curvature adjuster 212. The curvature adjuster 212 is embedded into the transverse truss 221 through an opening on the support frame 22 and can be rotated within a certain angle range. The curvature adjuster 212 can be a pawl or a one-way valve or other rotary positioning device, so that it can adapt to various angle selections and lock at the required angle, thereby completing the initiation of rescue pipes 32 with different curvatures.

[0131] by Figure 3 The illustrated embodiment illustrates this. If the rescue route 61 is a straight line, the rescue pipe 32 is a straight pipe at the starting position 60. Therefore, the curvature adjusters 212 of each of the three pipe clamps 211 are adjusted so that the centers of the three pipe clamps 211 are on the same straight line. At this time, the limiting straight channel formed by the three pipe clamps 211 matches the straight pipe. If the rescue route 61 is a curve, the rescue pipe 32 is a curved pipe at the starting position 60. Therefore, the curvature adjusters 212 of each of the three pipe clamps 211 are adjusted so that the centers of the three pipe clamps 211 coincide with the center of the rescue pipe 32 at their respective positions (at this time, the centerline of the rescue pipe 32 is curved). At this time, the limiting curved channel formed by the three pipe clamps 211 matches the curved pipe, avoiding the offset stress generated on the rescue pipe 32 due to improper limiting, and thus avoiding the offset stress generated on the rescue pipe 32 from affecting the tunneling direction of the tunneling host 31, causing the tunneling direction to deviate.

[0132] According to one embodiment of the present invention, such as Figures 1 to 3 As shown, the support frame 22 is also equipped with a jacking mechanism 23. The jacking mechanism 23 includes a jacking cylinder 231 installed in the support frame 22. A pipe clamp 232 is connected to the hydraulic rod of the jacking cylinder 231. The pipe clamp 232 is sleeved on the circumferential outside of the rescue pipe 32.

[0133] The jacking mechanism 23 provides power for the forward movement of the tunneling host 31. The jacking mechanism 23 acts on the pipe clamp 232 through the hydraulic rod of the jacking cylinder 231. The pipe clamp 232 acts on the rescue pipe 32 through the reaction force provided by friction, and under the action of the jacking force, it drives the tunneling host 31 and the rescue pipe 32 forward.

[0134] Specifically, such as Figure 2 and Figure 3As shown, the pipe clamp 232 includes two semi-circular jaws joined together. The clamping force generated between the two jaws tightly connects the pipe clamp 232 to the rescue pipe 32. Each jaw is connected to a jacking cylinder 231. The end of the hydraulic rod of the jacking cylinder 231 is connected to the jaw. The extension direction of the hydraulic rod is the same as the extension direction of the pipe delivery channel 224. The cylinder body of the jacking cylinder 231 is fixed on the support frame 22. The number of jacking cylinders 231 can be selected according to actual needs to ensure that the tunneling device 30 has sufficient thrust during its forward movement, thereby ensuring that the tunneling device 30 has a large forward speed during the rescue process.

[0135] According to one embodiment of the present invention, such as Figures 1 to 3 As shown, a base 25 is detachably connected to the bottom of the support frame 22. One side of the base 25 is connected to the transport device 10, and an angle adjustment rod 252 for adjusting the angle of the support frame 22 is connected between the other side of the base 25 and the support frame 22.

[0136] The angle adjustment rod 252 can adjust the angle of the support frame 22, that is, it can adjust the launching angle of the launching device 20, thereby adapting to different rescue routes 61. The base 25 can provide a window for launching rescue equipment, and under the gravity of the counterweight 261, it can stabilize the launching system and compact the surface soil.

[0137] The base 25 is made of steel components connected by welding or bolts. It is located at the bottom of the support frame 22 and is detachably connected to the support frame 22. One side of the base 25 is connected to the reinforcing steel beam 13 of the transport device 10 to ensure that the base 25 can be firmly pressed onto the ground during the tunneling process. One end of the angle adjusting rod 252 is fixedly connected to the base 25, and the other end is fixed to the lifting lug at the bottom of the support frame 22. The starting angle of the launching device 20 is controlled by controlling the extension and retraction of the angle adjusting rod 252. The angle adjusting rod 252 and the rotating hinge seat of the support frame 22 are located on both sides of the support frame 22, and the angle adjusting rod 252 can be a hydraulic cylinder.

[0138] During straight-line tunneling rescue operations, the base 25 and the support frame 22 remain connected, the angle adjustment rod 252 remains at zero position, and rubber pads 251 are installed at corresponding parts of the base 25 and the support frame 22 to ensure that the support frame 22 and the base 25 are in close contact. The rubber pads 251 can buffer the impact acceleration and impact force during the tunneling process, minimize the impact damage to the tunneling platform and equipment, and also reduce the vibration of the entire tunneling equipment.

[0139] During curved tunneling rescue operations, the base 25 is disconnected from the support frame 22, the angle adjustment rod 252 is activated, the support frame 22 rotates around the hinge seat, and the entire launching device 20 reaches the predetermined launching angle.

[0140] Better, such as Figure 2 As shown, a telescopic support rod 253 is provided between the support frame 22 and the transport device 10 on the side near the hinge seat. The telescopic support rod 253 can be a hydraulic cylinder, with one end fixed to the reinforcing steel beam 13 of the transport device 10 and the other end fixed to the middle lifting lug on the side of the support frame 22. The telescopic support rod 253 assists in the multi-angle adjustment of the launching device 20 through telescopic movement and can provide support force during the tunneling process to ensure the stability of the entire launching device 20.

[0141] Furthermore, such as Figure 2 As shown, a fixed support rod 254 is provided between the support frame 22 and the transport device 10 on the side near the hinge seat. The fixed support rod 254 can be a hydraulic cylinder, with one end fixed to the reinforcing steel beam 13 of the transport device 10 and the other end fixed to the top lifting lug on the side of the support frame 22. After the angle of the support frame 22 is adjusted, the position of the support frame 22 is further fixed by the fixed support rod 254, and it can provide support force during the tunneling process to ensure the stability of the entire launching device 20.

[0142] like Figure 1 , Figure 2 and Figure 12 As shown, the rescue equipment of the present invention also includes a tunneling device 30, which includes a tunneling host 31 and a rescue pipeline 32. The tunneling host 31 is a relatively mature excavation equipment in the prior art, and the specific structure and working distance of the tunneling host 31 will not be described here. In order to increase the rescue rate, it is necessary to control the diameter of the rescue pipeline 32 as much as possible and reduce the excavation volume. Therefore, it is usually necessary to select a tunneling host 31 with a smaller excavation diameter and higher tunneling efficiency.

[0143] The rear end of the tunneling machine 31 is connected to a rescue pipe 32. The rescue pipe 32 can move along the predetermined rescue route 61 with the tunneling machine 31. The portion of the rescue pipe 32 exposed above the ground is located in the pipe delivery channel 224 within the support frame 22, and this portion of the rescue pipe 32 passes through the curvature adjustment mechanism 21. The tunneling device 30 is driven by the launching device 20, which is also the drive connection between the jacking mechanism 23 and the rescue pipe 32 mentioned above, and will not be described again here.

[0144] According to one embodiment of the present invention, such as Figure 4 and Figure 9As shown, the rescue pipeline 32 includes a plurality of pipe sections 321 connected in sequence, each pipe section 321 including at least two segments that are aligned with each other.

[0145] Each pipe segment 321 on the rescue pipeline 32 adopts a splicing structure. When it is necessary to add pipe segments 321 one by one during downward excavation, multiple pipe segments can be directly placed on the pipeline 50 connected to the tunneling host 31, and then spliced ​​to form the corresponding pipe segment 321. That is, there is no need to cut the pipeline 50 on the tunneling host 31 during the process of adding pipe segments 321 one by one, which simplifies the connection operation between adjacent pipe segments 321.

[0146] Better, such as Figure 9 As shown, adjacent pipe sections 321 are connected by threads, and the tightening direction of the threads is the same as the rotation direction of the tunneling host 31. Adjacent pipe sections 321 are connected by bolts, which facilitates the connection and disassembly of the rescue pipeline 32, allowing the rescue pipeline 32 to be reused; the setting of the thread direction can prevent the adjacent pipe sections 321 from loosening during the rotation of the tunneling host 31.

[0147] According to one embodiment of the present invention, such as Figure 4 As shown, the rescue pipe 32 is provided with a guide rail 322 for the rescue device 40 to slide and connect, and the guide rail 322 extends along the length of the rescue pipe 32.

[0148] The guide rail 322 installed inside the rescue pipe 32 can guide the rescue device 40 to slide inside the rescue pipe 32, preventing it from rotating in the circumferential direction of the rescue pipe 32 during the sliding process, thereby affecting the safety of the trapped person 63 inside the rescue device 40; at the same time, the guide rail 322 also allows the rescue device 40 to be quickly lowered to the rescue point 62, preventing it from getting stuck inside the rescue pipe 32 during the lowering or lifting process.

[0149] Specifically, such as Figures 4 to 7 As shown, in this embodiment, the pipe section 321 includes a first pipe segment 323 and a second pipe segment 324 that are fitted together. Both the first pipe segment 323 and the second pipe segment 324 are semi-cylindrical pipe segments. Each pipe section 321 is provided with a guide rail 322 for sliding connection of the rescue device 40. The guide rails 322 in the sequentially connected pipe sections 321 are also sequentially connected together. In other embodiments of the present invention, the pipe section 321 may also be composed of three or more pipe segments, which is not specifically limited here.

[0150] The first segment 323 and the second segment 324, which are fitted together, form a first butt joint 325 and a second butt joint 326. A guide rail 322 is located at the first butt joint 325, and the extension direction of the guide rail 322 is the same as the extension direction of the first butt joint 325. The fixed side of the guide rail 322 is welded to the first segment 323, and the suspended side of the guide rail 322 is provided with a threaded hole for threaded connection with the second segment 324. The second segment 324 is provided with a bolt hole near the first butt joint 325. When the first segment 323 and the second segment 324 are assembled, the bolt hole on the second segment 324 is aligned with the threaded hole on the suspended side of the guide rail 322, and then the bolt is screwed in from the outside of the second segment 324 to ensure a tight connection between the first segment 323 and the second segment 324.

[0151] Better, such as Figure 5 and Figure 6 As shown, the second segment 324 has a pre-drilled groove for the bolt head at the bolt hole on the outside of the pipe wall. This prevents a large bulge from appearing on the outside of the second segment 324 after the bolt is tightened, thus reducing the resistance brought by the bolt during the excavation of the rescue pipeline 32.

[0152] The guide rail 322 is positioned at the first joint 325 of the first segment 323 and the second segment 324, serving as a connector at the first joint 325. This simplifies the connection operation of the first joint 325 and also improves the structural strength at the first joint 325.

[0153] Furthermore, such as Figure 4 , Figure 7 and Figure 8 As shown, an I-beam connector 33 is provided at the second joint 326. The I-beam connector 33 has two opposing positioning plates 331 and a clamping plate 332 connected between the two positioning plates 331. The clamping plate 332 is located inside the second joint 326. One of the positioning plates 331 is attached to the outer side of the first segment 323 and the outer side of the second segment 324, and the other positioning plate 331 is attached to the inner side of the first segment 323 and the inner side of the second segment 324. A bolt passes through the two positioning plates 331.

[0154] The outer walls of the first segment 323 and the second segment 324 have grooves for installing positioning plates 331 near the second joint 326. One of the positioning plates 331 of the I-beam connector 33 can be embedded in the groove, thereby avoiding the increase of frictional resistance of the pipe wall caused by the protrusion of the outer part of the pipe, which would reduce the efficiency of rescue.

[0155] The outer positioning plate 331 has multiple bolt holes, and the inner positioning plate 331 has multiple threaded holes corresponding to the bolt holes. The first tube segment 323 and the second tube segment 324 also have bolt holes corresponding to the bolt holes. When the first tube segment 323 and the second tube segment 324 are assembled, the bolt holes on the first tube segment 323 and the second tube segment 324 are first aligned with the threaded holes on the positioning plate 331, and then the bolts are screwed in from the outside of the first tube segment 323 and the second tube segment 324 to ensure a tight connection between the first tube segment 323 and the second tube segment 324. Then, the connection at the first butt joint 325 mentioned above is performed.

[0156] Preferably, a groove for the bolt head is pre-reserved on the outer wall of the positioning plate 331 at the position corresponding to the bolt hole. This prevents a large bulge from appearing at the position of the second joint 326 after the bolt is tightened into the pipe segment, thus reducing the resistance brought by the bolt during the excavation of the rescue pipeline 32.

[0157] The first segment 323 and the second segment 324 are connected at the second joint 326 using an I-beam connector 33. Compared with relatively conventional connection methods such as welding, the I-beam connector 33 can provide better connection strength, ensuring that the spliced ​​pipe section 321 does not crack or deform in the high-pressure underground environment.

[0158] Meanwhile, the bolts used for fixing at the first joint 325 and the second joint 326 are all screwed in from the outside of the rescue pipe 32, which is relatively convenient to operate and has a high level of safety; and nuts are omitted, leaving as much rescue space as possible inside the rescue pipe 32.

[0159] Of course, in other embodiments of the present invention, the connection structure of the first segment 323 and the second segment 324 at the second joint 326 can also be interlocked with each other in a mortise and tenon structure, without the need for additional fastening connectors, so as to ensure that the pipe section 321 formed by splicing the segments has high structural strength.

[0160] According to one embodiment of the present invention, such as Figures 6 to 8 As shown, both the first joint 325 and the second joint 326 are equipped with water-stop strips 34. The water-stop strips 34 can enhance the waterproofness of the rescue pipe 32 and prevent groundwater from entering the rescue pipe 32, thereby preventing the rescue operation from being carried out smoothly.

[0161] Specifically, such as Figure 6 As shown, at the first joint 325, the waterstop strip 34 is directly installed in the gap formed between the first segment 323 and the second segment 324. Figure 7As shown, at the second joint 326, a waterstop strip 34 is disposed in the gap formed by the clamping plate 332 and the first segment 323, and also in the gap formed by the clamping plate 332 and the second segment 324; further, as Figure 8 As shown, waterstop strips 34 are also provided in the gap between the positioning plate 331 and the first tube segment 323, and in the gap between the positioning plate 331 and the second tube segment 324.

[0162] like Figure 13 and Figure 14 As shown, the rescue equipment of the present invention also includes a rescue device 40. After the tunneling device 30 tunnels to the rescue point 62, the rescue device 40 is slidably installed in the rescue pipe 32 and lowered down to the rescue point 62 along the rescue pipe 32. The trapped personnel 63 at the rescue point 62 are transported out along the rescue pipe 32 through the rescue device 40.

[0163] The rescue device 40 includes a lying board 41 for accommodating the trapped person 63, and a main roller assembly and an auxiliary roller assembly on the outer side wall of the lying board 41. The main roller assembly rolls in cooperation with the guide rail 322, and the auxiliary roller assembly rolls in cooperation with the rescue pipe 32. A set of auxiliary roller assemblies is provided on each side of the main roller assembly.

[0164] The lying board 41 is an arc-shaped board with the same circumferential curvature as the rescue pipe 32, which can be used for the trapped person 63 to lie down; the main roller assembly rolls on the guide rail 322, and the main roller assembly that rolls in cooperation with the guide rail 322 can ensure that the lying board 41 moves forward along a predetermined route without deviating; the auxiliary roller assembly rolls on the inner wall of the rescue pipe 32, and the auxiliary roller assembly can effectively transport the rescue device 40 in the arc-shaped arch position inside the rescue pipe 32, provide lateral support for the lying board 41, and correct the deviation of the rescue device 40 in real time.

[0165] Better, such as Figure 13 As shown, the main roller assembly includes two main rollers 42 located on both sides of the guide rail 322, which can roll on the side walls of the guide rail 322 respectively. The tops of the two main rollers 42 are tangent to the side walls of the guide rail 322, which can provide lateral guidance when the rescue device 40 moves and provide guiding force when making curvature turns.

[0166] Furthermore, such as Figure 14 As shown, the main roller assembly includes a plurality of main rollers 42 spaced apart along the length of the lying plate 41, and the auxiliary roller assembly includes a plurality of auxiliary rollers 43 spaced apart along the length of the lying plate 41. The plurality of main rollers 42 and the plurality of auxiliary rollers 43 arranged along the length of the lying plate 41 provide multiple support points for the lying plate 41, ensuring its stability during movement.

[0167] According to one embodiment of the present invention, such as Figure 14As shown, the end of the deck 41 away from the tunneling host 31 is connected to a cable 44, and the other end of the cable 44 extends along the length of the rescue pipe 32 and is connected to a traction mechanism on the ground; the traction mechanism connected to the other end of the cable 44 can control the lowering or raising of the deck 41.

[0168] Preferably, in order to avoid the problem of the cable 44 getting tangled and locked, the bottom of the rescue device 40 can be equipped with a drive mechanism, which drives the main roller 42 to transport along the guide rail 322, that is, the rescue device 40 adopts a self-driven method.

[0169] According to one embodiment of the present invention, such as Figure 14 As shown, the upper end of the reclining board 41 is connected to the upper guard plate 45 and the lower guard plate 46 respectively. The lower guard plate 46 is provided with foot buckles 47. The reclining board 41 is provided with handrails 48 on both sides and a safety belt 49 is provided inside the reclining board 41.

[0170] The upper guard plate 45 and the lower guard plate 46 can ensure that the person is not entangled or scratched by the pipes 50, slag and other debris inside the pipeline during the rescue of the trapped person 63. The lower guard plate 46 is used to support the weight of the trapped person 63 and is equipped with a safety belt 49 and foot buckle 47 to fix the body of the trapped person 63. At the same time, the trapped person 63 can correct his posture through the handrail 48 to avoid secondary injury during the rescue.

[0171] The structure and technical effects of the preferred embodiment of the rescue equipment described in this invention will be further explained below.

[0172] To increase the rescue speed, the diameter of the rescue pipe 32 needs to be controlled as much as possible to reduce the amount of excavation. After the tunneling machine 31 completes the tunneling operation, in order to leave sufficient escape space for the trapped personnel 63, the pipe bundles and debris inside the pipe need to be cleared.

[0173] Therefore, as Figure 10 and Figure 11 As shown, according to one embodiment of the present invention, the tunneling host 31 is connected to a pipeline bundle located in the rescue pipeline 32. Each pipeline 50 in the pipeline bundle is provided with a disconnection mechanism 51 between it and the tunneling host 31. The pipeline bundle can be disconnected from the tunneling host 31 by the disconnection mechanism 51 after the tunneling device 30 tunnels to the rescue point 62, and can be pulled out from the rescue pipeline 32.

[0174] The disconnection mechanism 51 can disconnect the pipeline bundle from the tunneling host 31 after the tunneling is completed, so that the pipeline bundle can be pulled out from the rescue pipeline 32, making enough space for the installation of the rescue device 40 and avoiding the presence of the pipeline bundle from affecting the movement of the rescue device 40.

[0175] Specifically, the disconnection mechanism 51 includes a sleeve 511 and a lock cylinder 512 that are engaged with each other. The lock cylinder 512 is located inside the sleeve 511, which is connected to the tunneling host 31. The lock cylinder 512 is connected to the end of the pipeline 50. The inner wall of the sleeve 511 is provided with multiple locking tongues 513 that can extend and retract in the radial direction of the sleeve 511. An electromagnetic suction seat 515 is provided between the multiple locking tongues 513 and the inner wall of the sleeve 511. A spring 516 is provided between the electromagnetic suction seat 515 and the locking tongues 513. The locking tongues 513 are made of magnetic material. The outer wall of the lock cylinder 512 is provided with multiple snap-fit ​​grooves 514 that engage with the locking tongues 513.

[0176] When the electromagnetic suction seat 515 is de-energized, the locking tongue 513 extends radially inward under the action of the spring 516 and locks itself in the latching groove 514. When the electromagnetic suction seat 515 is energized, the locking tongue 513 retracts radially outward under the action of electromagnetic force and disengages from the latching groove 514. When the tunneling device 30 tunnels to the rescue point 62, the electromagnetic suction seat 515 is energized, and the locking tongue 513 retracts radially outward to separate the sleeve 511 and the lock core 512, that is, the connection between the pipeline 50 and the tunneling host 31 is disconnected, and then the disconnected pipeline 50 is pulled out from the rescue pipeline 32.

[0177] In other embodiments of the present invention, the connection positions of the sleeve 511 and the lock cylinder 512 can be interchanged, that is, the lock cylinder 512 is connected to the tunneling host 31, and the sleeve 511 is connected to the end of the pipeline 50.

[0178] According to one embodiment of the present invention, such as Figure 10 and Figure 11 As shown, the sleeve 511 is provided with a connecting pipe 517 that can mate with the lock cylinder 512, and a sealing ring 518 is provided between the connecting pipe 517 and the lock cylinder 512. One end of the connecting pipe is connected to the lock cylinder 512, and the other end is connected to the tunneling host 31. The connecting pipe can serve as a transfer pipe between the lock cylinder 512 and the tunneling host 31, thereby realizing the connection between the rescue pipe 32 and the tunneling host 31; the sealing ring 518 can prevent leakage at the mating position of the lock cylinder 512.

[0179] According to one embodiment of the present invention, such as Figure 12 As shown, a retractable rescue door 35 is provided on the side wall of the end of the rescue pipe 32 that is connected to the tunneling host 31; the rescue door 35 facilitates the entry of the trapped personnel 63 into the rescue device 40 inside the rescue pipe 32.

[0180] According to one embodiment of the present invention, such as Figure 12 As shown, a guide mechanism 36 is provided on the inner wall of the end of the rescue pipeline 32 that is connected to the tunneling host 31; the guide mechanism 36 can help determine the distance between the tunneling host 31 and the rescue point 62 in real time, so as to avoid deviation of the tunneling route.

[0181] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, an angle-adjustable working platform 24 is provided on the outer side of the support frame 22. The working platform 24 includes an operating plate 241 connected to the support frame 22 and a telescopic rod 242 connecting the operating plate 241 and the support frame 22. The telescopic rod 242 can extend and retract with the tilt of the support frame 22 so that the operating plate 241 is always in a working state with a fixed angle. In the working state, the operating plate 241 usually needs to be kept in a horizontal state so that the operator can stand. The angle of the operating plate 241 can adapt to the different angles of tunneling required by the launching device 20, meet the operational needs under various working conditions, and ensure that rescue personnel can stand on the working platform 24 to perform corresponding operations regardless of the launching angle.

[0182] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a counterweight 261 is placed on the transport device 10, and a temporary base 26 is connected to the launching device 20. A counterweight 261 is also placed on the temporary base 26, which is connected to the side of the base 25 away from the transport device 10. The counterweight 261 mainly provides reaction force for tunneling and ensures the stability of the rescue equipment under the action of gravity.

[0183] Implementation

[0184] like Figures 15 to 19 As shown, the present invention also provides a rescue method, which is implemented using the rescue equipment described in Embodiment 1, and includes the following steps:

[0185] Step S1: The transport device 10 carries various equipment to the rescue site, quickly surveys the accident site and accurately locates the underground rescue point 62, formulates the best tunneling rescue route 61 and starting position 60, and selects a rescue pipe 32 with the same shape as the rescue route 61.

[0186] Step S2: Install the positioning launching device 20 at the starting position 60, and adjust the angle of the launching device 20 according to the planned tunneling rescue route 61;

[0187] Step S3: Install the tunneling host 31 and connect the rescue pipe 32 that matches the tunneling rescue route 61 to the tunneling host 31, while adjusting the curvature adjustment mechanism 21 on the starting device 20 to match the curvature of the rescue pipe 32.

[0188] Step S4: Start the launching device 20 and the tunneling host 31. The tunneling host 31 tunnels along the tunneling rescue route 61 toward the underground rescue point 62.

[0189] Step S5: After the tunneling host 31 has tunneled into place, the rescue device 40 is lowered to the underground rescue point 62 along the rescue pipeline 32;

[0190] Step S6: After the trapped person 63 enters the rescue device 40, the rescue device 40 is pulled back to the ground along the rescue pipe 32.

[0191] The rescue method described in this invention can quickly achieve a rescue response, and can accurately, rapidly, and in multiple ways open life channels to carry out rescue operations. It can be widely applied to the rescue of collapse accidents during the construction and use of underground spaces, and can also be used for the rescue of collapse accidents in underground caverns such as underground coal mines, highway tunnels, and culverts.

[0192] Specifically, in step S1, after receiving the distress call from the trapped person 63, the rescuers select a suitable transport device 10 (wheeled or tracked vehicle) based on the ground conditions at the accident location. The transport device 10 is used to quickly transport various rescue equipment to the accident location. Upon arrival at the accident location, a rapid geological survey and risk assessment are conducted at the accident site to accurately locate the underground rescue point 62. Based on the underground rescue point 62, the optimal tunneling rescue route 61 and starting position 60 are determined. At the same time, based on the determined rescue route 61, a rescue pipe 32 with the same shape is selected. That is, when the rescue route 61 is curved, a rescue pipe 32 with the corresponding curvature needs to be selected.

[0193] like Figure 15 As shown, a straight rescue route and a curved rescue route were proposed based on the location of underground rescue point 62; to illustrate that the rescue equipment described in this invention can be used for both straight and curved rescues simultaneously, Figures 15 to 19 The document shows the rescue process for both routes. In actual rescue operations, only the safer and faster rescue route 61 needs to be selected.

[0194] In step S2, after determining the rescue route 61 and the starting position 60, the starting device 20 is moved above the starting position 60 by the transport device 10, and then the transport device 10 is fixed, connecting the base 25 and the temporary base 26. At the same time, a counterweight 261 is placed on the temporary base 26 and the transport device 10. Then, the angle of the starting device 20 is adjusted according to the determined rescue route 61, that is, the angle adjustment rod 252 and the telescopic support rod 253 on the support frame 22 are adjusted simultaneously. After reaching the specified angle, the starting device 20 is fixed to the transport device 10. Then, various functional components are connected to the starting device 20 to prepare for the tunneling start. Corresponding auxiliary construction equipment 66 can also be set up on the ground.

[0195] In step S3, after the starting device 20 is adjusted, the tunneling host 31 is installed at the starting position 60 and a rescue pipeline 32 matching the tunneling rescue route 61 is connected to the tunneling host 31. The rescue pipeline 32 is spliced ​​from multiple pipe sections 321. Therefore, before the tunneling starts, only a small number of pipe sections 321 can be connected to the tunneling host 31, and the remaining pipe sections 321 can be spliced ​​in real time during the subsequent tunneling process. At the same time, the diameter and position of multiple pipe clamps 211 in the curvature adjustment mechanism 21 are adjusted so that the curvature of the pipe channel formed between the multiple pipe clamps 211 is the same as the curvature of the rescue pipeline 32 at that position.

[0196] In step S4, after all the preparatory work before tunneling is completed, the launching device 20 and the tunneling host 31 are started. The tunneling host 31 tunnels along the tunneling rescue route 61 toward the underground rescue point 62. During the tunneling process, the rescue personnel on the ground add pipe sections 321 to the end of the rescue pipe 32 in real time. At the same time, the guide mechanism 36 at the head of the rescue pipe 32 helps to judge the distance between the tunneling host 31 and the rescue point 62, and thus judge whether the tunneling direction has deviated.

[0197] In step S5, after the tunneling host 31 tunnels to the rescue point 62, the rescue device 40 is lowered to the underground rescue point 62 along the rescue pipeline 32. The rescue device 40 can be used to ventilate the underground rescue point 62, deliver water, food, oxygen, medical and other rescue supplies 67, and establish real-time communication to obtain information about the rescue point 62.

[0198] Preferably, if the pipeline 50 connected to the tunneling host 31 is equipped with a disconnection mechanism 51, the connection between the pipeline 50 and the tunneling host 31 needs to be disconnected by the disconnection mechanism 51 before the rescue device 40 is lowered, and the pipeline 50 in the rescue pipeline 32 is pulled out from the rescue pipeline 32.

[0199] In step S6, the trapped personnel 63 at rescue point 62 can open the rescue door 35 at the head of rescue pipe 32 and take out the rescue supplies 67 in rescue device 40 for temporary emergency use. Then, the trapped personnel 63 can be rescued one by one through rescue device 40 along rescue pipe 32 and brought back to the ground. After the rescue is completed, rescue pipe 32 and tunneling host 31 are recovered until all rescue equipment is recovered.

It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
