Description

Technical Field

[0001] The present invention belongs to the technical field of mine and tunnel emergency rescue, and in particular relates to a modular roadway and tunnel life channel rapid construction device. Background Art

[0002] When a narrow tunnel collapses in a mine, people are trapped inside with no escape route. How to quickly open a rescue channel within the collapsed tunnel within a specified timeframe and rescue the trapped people quickly is an urgent problem that needs to be solved. Existing tunnel (tunnel) rapid rescue equipment has the following technical drawbacks:

[0003] 1) Existing lane (tunnel) rapid rescue equipment has many power sources, including cutter head rotation power source, jacking power source, slag discharge power source, coal slag transportation power source, and pipe jacking transportation power source. The probability of problems increases. No matter which power source has a problem, the rescue will be interrupted, and the installation is complicated.

[0004] 2) The slag transport track and pipe jacking transport track of the existing roadway (tunnel) rapid rescue equipment are arranged on the side of the main machine, resulting in the overall equipment occupying a large area in the roadway, which is obviously unreasonable in the roadway with limited space.

[0005] 3) The front end of the drill bit of the existing lane (tunnel) rapid rescue equipment is flat, and drilling in the flat surface will cause too much resistance.

[0006] 4) Existing lane (tunnel) rapid rescue equipment and shield-free pipe lifting device.

[0007] 5) The existing slag discharge system of the rapid rescue equipment in the lane (tunnel) has a complex structure. There is a scraper conveyor inside the pipeline, and the slag transport car and the mine car transport track outside the pipeline. The scraper inside the pipeline is driven by a motor, and the slag falls into the slag transport car from the chute. After the mine car is filled with slag, it is pulled away by the winch, and then the empty mine car is placed in the chute position. The full mine car transfers the slag to the designated location and then transports the mine car back. There are many steps in the transportation of slag, and each time the shield push pipeline is installed, the disassembly and assembly of the chain and scraper is tedious and time-consuming, and the overall installation and commissioning is also relatively complicated.

[0008] 6) The existing shield push system of the rapid rescue equipment for lanes (tunnels) cannot be disassembled and assembled as a whole, is relatively bulky, and is inconvenient to transport.

[0009] 7) The existing transportation method of rapid rescue equipment in lanes (tunnels) is single.

[0010] 8) The drill bit of the existing lane (tunnel) rapid rescue equipment cannot be retracted at any time, and the advancement and retraction speeds cannot be adjusted. Summary of the Invention

[0019] The operating system is arranged in the middle of the Shield Push system, and includes an operating panel and an operating box, and is used to operate the equipment through the operating panel.

[0020] Furthermore, wheel sets, rubber wheels or tracks for tunnel transportation are provided below the hydraulic jacking module, hydraulic motor module and shield push tube module.

[0021] Furthermore, the hoisting system includes a plurality of single pillars and slides, the single pillars and slides are assembled separately, and the slides are connected to the single pillars and are used to transport the shield push tube to the tube assembly area.

[0022] Furthermore, the rock-breaking drill bit adopts a tower drill bit, which is arranged at the front end of the tube, is a composite telescopic type, and can be assembled in detachable parts.

[0023] Furthermore, the diameter of the tail of the tower drill bit is larger than the diameter of the shield push tube, so as to reduce the friction between the shield push tube and the rock and soil.

DETAILED DESCRIPTION

[0038] The present invention is described in detail below with reference to the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in this field based on these embodiments are all within the scope of protection of the present invention.

[0039] This embodiment provides a modular equipment for rapid construction of life channels in lanes and tunnels, including a rock-breaking drill bit system 1, a shield pushing system 2, a hydraulic system 3, a waste slag conveying system 4, a hoisting system 5, and an operating system 6. Each system adopts a modular design and can be detachably connected; among them, the rock-breaking drill bit system 1, the shield pushing system 2, the hydraulic system 3, and the waste slag conveying system 4 are connected in sequence.

[0040] The shield pusher system 2 comprises a detachably connected hydraulic pusher module 21 (module 1), a hydraulic motor module 22 (module 2), and a shield pusher tube module 23 (module 3). Each of these modules has its own bottom track. The shield pusher tube module 23 includes a guide tube and tube support for mounting the shield pusher tube 24.

[0041] The rock-breaking drill bit system includes a transmission shaft with spiral blades connected to each other inside the shield push tube 24 and a rock-breaking drill bit 11 at the front end of the equipment; each section of the transmission shaft is equal to the length of the shield push tube 24. After one section of the shield push pipe and transmission shaft is pushed in, the second section of the pipe and the transmission shaft inside are inserted, and each transmission shaft is connected with screws.

[0042] The hydraulic thrust module 21 is connected to the hydraulic system 3 and powered by the rear hydraulic system 3. This provides high-tonnage thrust for the entire shield system, enabling multi-speed (infinitely variable) advancement and retraction of the shield tube 24 and rock-breaking drill bit 11. The hydraulic motor module 22 provides high-torque power to drive the rock-breaking drill bit 11 during drilling. The hydraulic system 3 utilizes a dual-stage propulsion system, comprising a main, long-distance, high-tonnage cylinder group and an auxiliary, short-distance, high-tonnage cylinder group.

[0043] The hoisting system 5 is arranged on the upper side of the shield push system 2 and is used to transport the shield push tube 24 from the tail of the equipment (tube loading area 25) to the tube assembly area 26, providing convenience for assembling the tube.

[0044] The waste slag conveying system 4 includes a spiral fan blade arranged on the transmission shaft inside the shield push tube, a belt conveyor 41 and a waste slag chute 42 arranged below the shield push system 2; the spiral fan blade uses the transmission force of the transmission shaft as the power source, and is used to perform spiral discharge while the rock breaking drill bit 11 is drilling; the slag falls onto the belt conveyor through the tube chute and is transported out through the waste slag chute 42. The waste slag conveying system adopts a spiral discharge and inlaid belt material transportation method. This method reduces the power source, that is, the power source of the spiral discharge is the same as the power source of the drill bit drilling. While the drill bit is drilling, the rear part is spirally discharged. In addition, the belt conveyor is arranged below the shield push system to save space, which is very beneficial in tunnels with limited space.

[0045] The operating system 6 is located in the middle of the shield push system and consists of an operating panel and an operating box. The operating panel is equipped with a main push operating stepless speed regulating handle and a main push pressure gauge, which are used to operate the main push oil cylinder to move forward, stop, and retreat and display the working pressure. During the operation, the operating handle controls the running speed of the main push oil cylinder, and the speed can achieve any speed of 0-1m / min. The main push oil cylinder can be switched to move forward, pause, retreat and other action functions at any time, and the pressure gauge displays the main push oil cylinder pressure. The auxiliary push operating handle and pressure gauge are used to operate the auxiliary push oil cylinder to move forward, stop, retreat and display the working pressure. The operating handle can realize the stepless speed change of the auxiliary push oil cylinder forward and retreat. The reverse thrust operating handle and pressure gauge are used to operate the reverse thrust cylinder forward, stop, and reverse and display the working pressure. The belt conveyor operating handle and pressure gauge are used to operate the belt conveyor hydraulic motor forward, stop, and reverse and display the working pressure. The belt speed can be operated at any speed under the control of the handle, and the belt speed can be adjusted according to the change of material quantity. The rotary operating handle and pressure gauge are used to operate the hydraulic motor that drives the spiral blades and drill bit to rotate forward, stop, and reverse and display the working pressure. The speed of the hydraulic motor that drives the spiral blades and drill bit can be adjusted at any time. The operating box is equipped with an integrated control valve to realize trouble-free operation of each action. The overall box adopts an integrated design to reduce space. The valve path structure is optimized to reduce the operating pressure drop and pipeline loss.

[0046] In this embodiment, a wheel set 27 (suitable for track gauges of 600mm / 900mm / 1000mm), rubber wheels or tracks for tunnel transportation are provided below the hydraulic jacking module 21, the hydraulic motor module 22 and the shield push tube module 23.

[0047] In this embodiment, the hoisting system 5 includes multiple single pillars 51 and slides 52 . The single pillars 51 and the slides 52 are assembled separately. The slides 52 are connected to the single pillars 51 and are used to transport the shield pusher tube 24 to the tube assembly area 26 .

[0048] In this embodiment, the rock-breaking drill bit 11 adopts a tower drill bit, which is a composite telescopic type (a multi-pole telescopic tower cone drill bit structure) and can be assembled in parts for easy transportation.

[0049] In this embodiment, the front end diameter of the drill bit is the smallest and the tail diameter is the largest, which can reduce the thrust resistance and achieve over-excavation, that is, the drill bit diameter is larger than the diameter of the shield push tube 24, which can reduce the friction between the shield push tube and the rock and soil.

[0050] In this embodiment, the tube adopts a quick connection fixing structure, which is convenient for rapid installation, pushing and pulling out.

[0051] In this embodiment, each tube section utilizes a parent-child structure at both ends, enabling seamless connection with the other tube section. The fixed connection between the tube sections utilizes an L-shaped quick-connect mechanism. For the same female tube end, two to four L-shaped notches are provided on one end of the tube wall, with one side of the L-shaped notch parallel to the tube axis and the other perpendicular to it. Each L-shaped notch is spaced 90 degrees apart or evenly spaced along the same plane. Two to four pins are provided on the outer wall of the other sub-tube end, with the same spacing and positioning as the sub-end. The pins are made of high-strength steel with a diameter of 10-30 mm. During the shield-push tube section installation process, the mating of the parent-child ends is adjusted. One end of the pin on the sub-end of the tube is inserted into the L-shaped notch on the other female tube end. Once the pin and hole are properly aligned, the sub-end and pin are inserted into the L-shaped notch parallel to the tube axis. A special tool is used to rotate the roller so that the pin is inserted into the L-shaped notch perpendicular to the tube axis, completing the installation.

[0052] In this embodiment, a spiral rod fast round-square corner connection method is adopted. The round-square corner connection realizes fast connection and fixed synchronous rotation function, realizing the overall rapid rescue concept.

[0053] In this embodiment, the spiral transmission shaft is a hollow tube structure, and the quick circle-square-angle connection method is that the two ends of the spiral rod shaft adopt a parent-child structure, the child end adopts a circle-square-angle end structure, the circle-square-angle end adopts an inscribed circle and 3-6 square structure, and the mother end adopts a square hole structure that matches the child end, and the length of the parent and child are adapted to each other. The child end is connected to the other mother end, and the circle section of the child end guides the square section to rotate synchronously, that is, to ensure that the axis of the two shafts can be automatically adjusted when the circle is centered, and the square section has a fixed synchronous rotation effect. According to the working conditions, the mother end is provided with corresponding threaded holes on the side, and the threaded holes are provided at the side. After the mother-child end shaft connection is installed in place, the fixing bolts can be installed through the bolt holes to fix the mother-child ends, prevent the mother-child shaft from sliding in the axial direction, and ensure the smooth retreat of the spiral shaft. Repeat the work according to the work needs. This invention, based on spiral micro-jacking construction, fully integrates the on-site working conditions of the roadway (tunnel), fully adopts hydraulic drive to achieve shield pushing and crushing excavation, and dry discharge at the rear of the spiral. The large-tonnage jacking force and high torque power drive the rock-breaking drill bit to drill, realizing the rapid construction of a rescue channel. During the rapid rescue process of roadway (tunnel) collapse, a steel structure channel is constructed to facilitate personnel escape. It is not only strong, safe and reliable, but also prevents rescue interruptions caused by re-crushing and secondary collapse of the loose landslide surrounding rock.

[0054] This invention uses the thrust generated by the shield pusher system to overcome friction between the pipe and the coal slag and rock, pushing the pipe into the channel drilled by the tower drill bit. The debris is then removed from the pipe through a dry discharge system at the rear of the spiral. The debris then falls through the pipe chute onto a conveyor belt for transport. After one section of the shield pusher pipe is pushed in, the second section is lowered to continue the process.

[0055] The present invention includes the following technical effects:

[0056] 1) The drill driving power source, spiral slag removal rotation power source and shield propulsion power source of the present invention are the same power source, all of which are fully explosion-proof hydraulically driven, with high installation efficiency, reduced probability of problems, and increased rescue success rate.

[0058] 3) The tower drill bit of the present invention can be assembled in parts, with the front end of the drill bit having the smallest diameter and the tail end having the largest diameter, which can reduce the thrust resistance and achieve over-excavation, that is, the drill bit diameter is larger than the tube diameter, which can reduce the friction between the shield tube and the rock and soil.

[0059] 4) The present invention is equipped with a lifting system that can transport the pipe from the rear of the equipment to the pipe assembly area, providing convenience for pipe assembly. The entire lifting system's individual pillars and slides can be assembled separately for easy transportation.

[0060] 5) The waste slag conveying system of the present invention adopts a spiral discharge and belt conveying method, which reduces the power source, that is, the power source of the spiral discharge is the same as the power source of the drill bit drilling. While the drill bit is drilling, the rear spiral discharges the material, and the slag falls into the belt conveyor from the chute. The belt conveyor keeps running to transport the slag to the designated location without the participation of slag transport vehicles; and when the shield push tube is installed, the transmission shaft with spiral fan blades inside is connected by pins, which is convenient for disassembly and assembly, thereby improving timeliness.

[0061] 6) The shield pusher system of the present invention adopts a modular design for easy transportation and assembly. It is divided into three modules, each of which can be transported separately: Module 1 is the hydraulic pusher module, Module 2 is the hydraulic motor module, and Module 3 is the shield pusher tube module. Each module has its own bottom track.

[0062] 7) The present invention sets wheels under each module of the shield push system for roadway transportation, which can be adapted to various track gauges. The wheels can also be replaced by rubber wheels and tracks to adapt to different transportation environments.

[0063] 8) The hydraulic jacking module of the shield pushing system of the present invention can realize multi-speed advancement and retraction of the shield pushing pipe and rock breaking drill bit.
