Description

Technical Field

[0001] The invention belongs to the field of rapid construction of small-scale rescue channels in coal mines, and in particular relates to a method for constructing an underground rescue channel and rescuing trapped persons. Background Art

[0002] Coal resources are the most important basic energy in my country, providing strong impetus and support for industrial development and social progress. As the depth of coal seam mining increases year by year, it gradually moves towards the deep mining stage, accompanied by the increasing risk of mine disasters such as rock burst, coal and gas outbursts, and roof collapse. When an accident occurs, the rapid rescue of trapped personnel underground is the primary task and goal of the rescue work, and how to quickly and efficiently build a safe and stable rescue channel in the tunnel accumulation body is the key and necessary condition for the successful rescue of trapped personnel.

[0003] At present, the construction methods of underground rescue channels are mainly divided into two types: traditional hydraulic support methods and new pipeline support methods. The hydraulic support method uses manual demolition and cleaning, hydraulic support support, to construct a large-section rescue channel that can pass rescue personnel, ensuring that rescue personnel can walk freely in the rescue channel. The large-section hydraulic support method is used to construct underground rescue tunnels. The excavation workload is large, the disturbance to the surrounding accumulation is large, time-consuming and labor-intensive, and the efficiency is low. The method of using pipeline support has the advantages of small disturbance, fast speed and good safety, and has good application prospects; however, facing the narrow space of underground tunnels, the distance from the ground, the difficulty of large rescue equipment going down the well, the long time, the poor working conditions for manually carrying accumulations in pipelines with a small radius, and the large physical consumption of rescue personnel relying on crawling when the rescue channel is long, the development of pipeline support methods is limited. Therefore, how to reduce the workload of manual demolition in pipelines and the physical exertion of rescue workers without using large shield machines or jacking machines, and speed up the rescue of trapped people underground is a difficult problem that needs to be overcome urgently. Summary of the invention

[0004] In view of the above existing problems, the present invention proposes a method for constructing an underground rescue channel and rescuing trapped persons, which can safely and efficiently construct a rescue channel in collapsed loose bodies underground, thereby facilitating the rescue of trapped persons.

[0005] To solve the above problems, the present invention provides the following technical solutions:

[0006] This solution provides a method for constructing an underground rescue channel and rescuing trapped persons, which includes the following three steps:

[0007] S1 Supporting round tubes enter the accumulation body: Use the reaming drill bit to destroy and drill into the accumulation body, and carry the supporting round tubes into the accumulation body;

[0008] S2 conveyor belt transports the crushed collapsed body: a conveyor belt is arranged inside the supporting circular tube, and the collapsed body crushed by the drill is transported to the entrance of the rescue channel through the conveyor belt, and transported and transferred by a trolley;

[0009] S3 Response and treatment during drilling: Take corresponding measures according to the drilling of the reamer and the supporting round pipe until the rescue channel is completed;

[0010] S4 Rescue of trapped persons: Rescuers used monkey vehicles in the rescue channel to safely rescue the trapped persons underground.

[0011] The response and processing of the drilling process in step S3 includes the following steps:

[0012] S31 uses the dust reduction component installed in front of the supporting circular tube to reduce the dust generated during the drilling process, reduce the amount of dust generated during the drilling process, and increase the visibility of the field of vision during the drilling process;

[0013] S32 uses the lighting device and camera probe in the visualization component to visually monitor the drilling situation near the reaming drill bit. When the volume of the accumulation body is large and difficult to completely crush, the rotary converter is adjusted to make the drill bit rotate around the axis to destroy, split and crush the large accumulation body that hinders the drilling direction, ensuring the normal progress of the drilling work.

[0014] S33 uses a metal detector to survey the anchor rods and anchor nets in the accumulation body ahead of drilling. When encountering metal materials during drilling, which are difficult for the reaming drill to break, the demolition assembly in front of the supporting circular tube is used to shear and remove them, thus reducing the scratches and damage to the reaming drill caused by the metal materials.

[0015] S34 and so on, effectively handle different situations that arise during the drilling process to ensure the normal drilling and support of the reaming drill bit and the supporting round pipe until the rescue channel is connected.

[0016] The rescue of the trapped person in step S4 comprises the following steps:

[0017] S41 After the rescue channel is connected, remove the reaming drill bit, drill rod and the conveyor belt above the conveyor belt from the supporting round tube;

[0018] S42 nests and connects the monkey car with the transport rail above the conveyor belt and the auxiliary rail below the self-rotating round tube, wherein the transport rail provides power for the movement of the monkey car;

[0019] The rescue stretcher placed between the two monkey cars of S43 is fixed by hinged connection holes of the rescue stretcher, which is convenient for the transfer and rescue of trapped persons.

[0020] The reaming drill bits are arranged in four directions of the supporting circular tube respectively. The reaming drill bits carry the supporting circular tube into the accumulation body through destruction and drilling. After the rescue channel is penetrated, the reaming drill bits are retracted and the supporting circular tube is withdrawn along with the drill rod.

[0021] The conveyor belt includes a conveyor belt, a conveyor roller and a transport guide rail, wherein the accumulation body is destroyed by the reaming drill bit and the demolition component to become a broken collapsed body, and then transported to the entrance of the rescue channel through the conveyor belt, and carried and transferred by a trolley; the transport guide rail provides power for the movement of the monkey car, transports rescue personnel and rescue materials, and reduces the physical exertion of rescue personnel in crawling.

[0022] A rotary converter is installed between the supporting circular tube and the autonomously rotatable circular tube. By adjusting the rotary converter, the autonomously rotatable circular tube can rotate along the axial direction, so that the drill bit can demolish the accumulation body in front in all directions and at multiple angles. A demolition component, a dust reduction component and a visualization component are installed from front to back on the inner side of the autonomously rotatable circular tube, wherein the visualization component includes a metal detector, a lighting device and a camera probe.

[0023] The monkey car includes a monkey car support rod, a monkey car seat, a monkey car material carrier and foot pedals. In the process of going to the working surface where the trapped persons are located, the rescue materials are placed on the monkey car material carrier to transport the materials and reduce the handling of rescue personnel; after the trapped persons are rescued, a rescue stretcher is installed between the monkey cars and fixedly connected in pairs, and the monkey car material carrier is used to transport the trapped persons.

[0024] The dust reduction component is installed in front of the supporting circular tube to perform atomization dust reduction treatment on the dust generated by the reaming drill bit during the drilling process, thereby reducing the dust generation during the drilling process and increasing the visibility of the field of view during the drilling process; the lighting device and camera probe in the visualization component perform visual monitoring and supervision of the drilling situation near the reaming drill bit; the metal detector surveys the anchor rods and anchor nets in the accumulation body in front of the drilling, thereby reducing the scratches and damage to the reaming drill bit caused by metal materials and increasing the service life of the drill bit.

[0025] The conveyor belt transports the crushed collapsed body to the entrance of the rescue channel via the conveyor belt, and uses a trolley to carry and transfer it, reducing the physical labor of workers in a small space and improving the construction efficiency of the rescue channel; after the rescue channel is connected, the monkey car is used to transport rescue workers and trapped people, which speeds up the rescue efficiency of the rescue work.

[0026] Due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] (1) The present invention adopts a rescue method in which a hole-reaming drill drills into the accumulation body, a belt conveys the crushed collapsed body, and rescuers ride on a monkey car to rescue the trapped persons, which greatly reduces the workload of manual work and improves the efficiency of rescue work;

[0028] (2) The present invention utilizes a reaming drill bit and a rotary converter to destroy, split and crush large-volume accumulations, and uses a demolition component to shear and remove metal materials, thereby realizing the construction of drilling and rescue channels in accumulations under complex conditions underground, and has the advantages of a wide range of applications and strong adaptability.

[0029] (3) The present invention utilizes dust reduction components and visualization components to perform visual detection and monitoring of the operating conditions of the reaming drill bit and the demolition component during the drilling process. While ensuring the rapid construction of the rescue channel, the advantages of the visualization component are utilized to reduce scratches and damage to the reaming drill bit, thereby achieving safe use of the device.

Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device, component or structure must have a specific direction, be constructed or operate in a specific direction, and should not be understood as a limitation on the present invention.

[0038] The specific implementation method of the present invention will be further described below in conjunction with the accompanying drawings.

[0039] This solution provides a method for constructing an underground rescue channel and rescuing trapped persons, which includes the following three steps:

[0040] S1: The supporting round tube enters the accumulation body: the accumulation body 9 is destroyed and drilled by the reaming drill bit 7, and the supporting round tube 1 is carried into the accumulation body 9;

[0041] S2 conveyor belt transports the crushed collapsed body: a conveyor belt 8 is arranged in the supporting circular tube 1, and the collapsed body 11 crushed by the drill bit is transported to the entrance of the rescue channel 10 through the conveyor belt 8, and is transported and transferred by a trolley;

[0042] S3 Response and treatment during drilling: according to the drilling of the reamer drill bit 7 and the support of the supporting round pipe 1, take corresponding measures until the rescue channel 10 is completed;

[0043] S4 Rescue of trapped persons: Rescuers take the monkey car in the rescue channel 10 to safely rescue the trapped persons underground.

[0044] The response and processing of the drilling process in step S3 includes the following steps:

[0045] S31 uses the dust reduction component 5 installed in front of the supporting circular tube 1 to reduce the dust generated during the drilling process, thereby reducing the amount of dust generated during the drilling process and increasing the visibility of the field of vision during the drilling process;

[0046] S32 uses the lighting device and camera probe in the visualization component 6 to visually monitor the drilling situation near the reaming drill bit 7. When the accumulation body 9 is large in volume and difficult to be completely crushed, the rotary converter 2 is adjusted to make the drill bit rotate around the axial direction to destroy, split and crush the large accumulation body 9 that hinders the drilling direction, thereby ensuring the normal progress of the drilling work;

[0047] S33 uses a metal detector to survey the anchor rods and anchor nets in the accumulation body 9 in front of the drilling. When metal materials are encountered during the drilling process and it is difficult for the reaming drill bit 7 to break them, the breaking assembly 4 in front of the supporting circular tube 1 is used to shear and dismantle them, thereby reducing the scratches and damage caused by the metal materials to the reaming drill bit 7;

[0048] S34 and so on, effectively handle different situations that occur during the drilling process to ensure the normal drilling and support of the reaming drill bit 7 and the supporting circular pipe 1 until the rescue channel 10 is connected.

[0049] The rescue of the trapped person in step S4 comprises the following steps:

[0050] S41 After the rescue passage 10 is connected, the reaming drill bit 7, the drill rod and the conveyor belt above the conveyor belt 8 are removed from the supporting circular tube 1;

[0051] S42 nests and connects the monkey car with the transport rail 12 above the conveyor belt 8 and the auxiliary rail below the self-rotating round tube 3, respectively, wherein the transport rail 12 provides power for the movement of the monkey car;

[0052] S43 The rescue stretcher 16 placed between the two monkey cars is fixed in an articulated manner through the rescue stretcher connecting holes 17, so as to facilitate the transfer and rescue of the trapped persons.

[0053] The reaming drill bit 7 is respectively arranged in four directions of the supporting circular tube 1. The reaming drill bit 7 carries the supporting circular tube 1 into the accumulation body 9 through destruction and drilling, and supports the accumulation body 9 above it to avoid secondary collapse and affect the stability of the overall structure of the accumulation body 9; after the rescue channel 10 is penetrated, the reaming drill bit 7 shrinks and the supporting circular tube 1 is withdrawn along with the drill rod, and the rescue channel is constructed, which is convenient for the subsequent rescue work.

[0054] like Figure 3As shown, the conveyor belt 8 includes a conveyor belt, a conveyor roller and a transport guide rail 12, wherein the accumulation body 9 is transformed into a broken collapsed body 11 after being destroyed by the reaming drill bit 7 and the demolition component 4, and then transported to the entrance of the rescue channel 10 through the conveyor belt, and transported and transferred by a trolley; the transport guide rail 12 provides power for the movement of the monkey car, transports rescue personnel and rescue materials, reduces the physical energy consumed by rescue personnel in crawling, and improves the efficiency of rescue work; the guide pulley 19 at the upper end of the monkey car is nested and connected with the auxiliary guide rail under the self-rotating circular tube 3, and the rescue personnel sit on the monkey car seat 14, place their feet on the pedals 15, and hold the monkey car support rod 13 with both hands, and carry out rescue work safely and smoothly in the rescue channel 10 under the power provided by the transport guide rail 12.

[0055] A rotation converter 2 is installed between the supporting circular tube 1 and the autonomously rotatable circular tube 3. By adjusting the rotation converter 2, the autonomously rotatable circular tube 3 can rotate along the axial direction, so that the drill bit can break the front pile 9 in all directions and at multiple angles. A breaking component 4, a dust reduction component 5 and a visualization component 6 are installed from front to back on the inner side of the autonomously rotatable circular tube 3, wherein the visualization component 6 includes a metal detector, a lighting device and a camera probe.

[0056] like Figure 4 As shown, the monkey car includes a monkey car support rod 13, a monkey car seat 14, a monkey car material rack 18 and a foot pedal 15. In the process of going to the working surface where the trapped persons are located, the rescue materials are placed on the monkey car material rack 18 for transporting materials, thereby reducing the handling of rescue personnel; after the trapped persons are rescued, a rescue stretcher 16 is installed between the monkey cars and fixedly connected in pairs, and the monkey car material rack 18 is used for transporting the trapped persons, thereby greatly reducing the physical exertion and labor intensity of the rescue personnel in a small space.

[0057] The dust reduction component 5 is installed in front of the supporting circular tube 1, and performs atomization dust reduction treatment on the dust generated by the reaming drill bit 7 during the drilling process, thereby reducing the dust generation during the drilling process and increasing the visibility of the field of view during the drilling process; the lighting device and the camera probe in the visualization component 6 perform visual monitoring and supervision of the drilling situation near the reaming drill bit 7; the metal detector surveys the anchor rods and anchor nets in the accumulation body 9 in front of the drilling, thereby reducing the scratches and damage to the reaming drill bit 7 caused by metal materials and increasing the service life of the drill bit.

[0058] The conveyor belt 8 transports the crushed collapsed body 11 to the entrance of the rescue channel 10 via the conveyor belt, and uses a trolley to carry and transfer it, reducing the physical labor of workers in a small space and improving the construction efficiency of the rescue channel 10; after the rescue channel 10 is connected, a monkey car is used to transport rescue workers and trapped people, which speeds up the rescue efficiency of the rescue work.

[0059] The rescue channel 10 is a small-sized rescue channel with an inner diameter of 0.8-1.2m. The construction method of the small-sized rescue channel has the advantages of small drilling workload and short construction period, which provides strong support for striving for the golden time for rescue; at the same time, the construction process of the small-sized rescue channel causes little disturbance to the overlying accumulation body 9, reduces the possibility of secondary collapse of the accumulation body 9, and ensures the life safety of rescue personnel during the rescue process.

[0060] The rescue channel 10 is suitable for the construction and rescue of long-distance rescue channels. The monkey car is used to transport personnel and rescue materials, which greatly reduces human labor and physical exertion, and provides strong support for rapid underground rescue.

[0061] At this point, those skilled in the art should recognize that, although the exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
