Description

Technical Field

[0001] The invention relates to the technical field of coal mine dust control, and in particular to a follow-up dust suction device for a roadheader. Background Art

[0002] The dust removal fan at the head of a conventional rock tunnel boring machine is installed on a single runway and connected to the tail of the second transport machine of the boring machine through a connecting rod. Therefore, when the boring machine cuts the kiln forward or backward, it needs to move back and forth on the runway with the dust removal fan. Due to the incorrect pulling of the tail and the fluctuating conditions in the tunnel, the runway is uneven and not straight, and the dust removal fan is very easy to derail or even cause rollover, which directly affects the normal operation of the dust removal fan and poses a huge safety hazard. It will also affect the comprehensive excavation construction and is not conducive to production.

Although the dust removal fan realizes the synchronous movement of the dust removal fan and the skeleton wind tube through the driving of the carrying trolley, the safety hazard of the dust removal fan derailing during rapid movement is eliminated, manpower and material resources are saved, and the dust prevention effect of the comprehensive excavation is improved. However, it actually adopts a hoisting method, which makes track installation difficult, and the movement of the dust removal fan is prone to safety hazards.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0028] like Figure 1 As shown, in this embodiment, the follow-up dust suction device of the tunnel boring machine includes: a vehicle body 10, a dust suction structure 20, a first identification structure, a controller and a collection structure. The vehicle body 10 has a running wheel 11. The dust suction structure 20 is arranged on the vehicle body 10, and the first end of the dust suction structure 20 has a dust suction port structure 21. The first identification structure is arranged on the vehicle body 10, and can detect the distance between the first identification structure and the tunnel boring machine. The controller controls the start and stop of the running wheel 11 according to the identification signal of the first identification structure. The collection structure is arranged at the second end of the dust suction structure 20. Among them, the direction of the dust suction port structure 21 can be adjusted.

[0029] By applying the technical solution of this embodiment, the dust suction structure 20 and the first identification structure are both arranged on the vehicle body 10, and the vehicle body 10 has a running wheel 11, so that the vehicle body 10 can move. The dust suction structure 20 can achieve dust suction through the dust suction port structure 21. The first identification structure can detect the distance between the vehicle and the tunnel boring machine, and can transmit the detected signal to the controller, and the controller can control the start and stop of the running wheel 11 according to the identification signal, so that the vehicle body 10 can move with the tunnel boring machine. The collection structure can collect smoke and dust. Through the above-mentioned setting, the vehicle body 10 can move synchronously with the tunnel boring machine, so that the dust suction effect of the dust suction structure 20 is better, and because the angle of the dust suction port structure 21 is adjustable, it can be targeted at the direction of smoke generation, thereby improving the dust suction effect. Due to the action of the running wheel 11, the vehicle body 10 has no fixed moving direction, that is, the vehicle body can move in any direction, so that the moving direction of the vehicle body is not restricted. Therefore, the technical solution of this embodiment effectively solves the problem that the moving direction of the dust removal fan in the related art depends on the track, thereby limiting its application scenario.

[0030] In practical applications, the follow-up dust collection device can significantly reduce the dust concentration inside mines and tunnels, improve the working conditions of operators, and reduce the incidence of respiratory diseases. For example, in coal mining, dust control is crucial because coal dust not only affects vision, but may also cause explosions. The follow-up dust collection device can work closely with the tunnel boring machine to remove dust immediately, effectively reduce the risk of explosion, and improve work safety. In tunnel construction, dust will also affect the health of workers and the progress of construction. The application of the follow-up dust collection device can improve air quality, reduce the chance of workers inhaling harmful dust, and improve construction efficiency and quality.

[0031] like Figure 1 As shown, in this embodiment, the follow-up dust suction device of the tunnel boring machine also includes a parking bracket 30 and a first driving member. The first end of the parking bracket 30 is hingedly connected to the vehicle body 10. The first driving member is arranged between the parking bracket 30 and the vehicle body 10. The parking bracket 30 has a recovery position and a support position. When the parking bracket 30 is in the recovery position, the distance between the second end of the parking bracket 30 and the vehicle body 10 is less than the distance between the second end of the parking bracket 30 and the ground. When the parking bracket 30 is in the support position, the second end of the parking bracket 30 cooperates with the ground support. The first driving member can drive the parking bracket 30 to switch between the recovery position and the support position. The controller can control the start and stop of the first driving member according to the identification signal of the identification structure. The setting of the parking bracket 30 not only ensures the stable storage of the follow-up dust suction device in the working state, but also improves the adaptability and safety of the equipment in complex terrain. It is suitable for tunneling operations in complex terrains such as mines and tunnels, and can effectively prevent the equipment from sliding or tipping over in a non-working state.

[0032] Specifically, by providing the parking bracket 30, the stability of the follow-up dust suction device of the tunnel boring machine in the working state is significantly enhanced, which prevents the equipment from sliding or tipping over due to uneven or tilted ground, reduces the risk of equipment damage, and also reduces the potential safety hazards of mine and tunnel operations. In complex terrain, the flexible adjustment capability of the parking bracket 30 enables the equipment to adapt to various ground conditions. Whether it is flat ground, slopes or potholes, the equipment can be stably stored, which enhances the flexibility and safety of the operation. For example, in the inclined shaft operation of a coal mine, the ground is tilted, and the parking bracket can provide additional support to ensure the stability of the equipment, prevent the equipment from sliding, and provide a stable foundation for the dust suction operation.

[0033] like Figure 1As shown, in this embodiment, the first identification structure includes a first visual detection structure and a first radar sensing structure, and the first visual detection structure and the first radar sensing structure are arranged at the first end of the vehicle body 10; the follow-up dust suction device of the tunnel boring machine also includes a second identification structure, and the second identification structure includes a second visual detection structure and a second radar sensing structure, and the second visual detection structure and the second radar sensing structure are arranged at the second end of the vehicle body 10. Through the dual identification of the first visual detection structure, the first radar sensing structure and the second visual detection structure, the detection accuracy of the first identification structure for the position and state of the tunnel boring machine is improved, ensuring that the follow-up dust suction device of the tunnel boring machine can accurately and timely follow the movement of the tunnel boring machine, especially in an environment with low visibility, the first radar sensing structure can provide reliable positioning information. It is suitable for tunneling operations such as mines and tunnels with low visibility and complex environments, and can effectively improve the adaptability and reliability of the equipment.

[0034] Specifically, the dual recognition technology of the first visual detection structure and the first radar sensing structure has significantly improved the positioning accuracy and environmental adaptability of the follow-up dust collection device of the tunnel boring machine. Even in an environment with extremely low visibility, it can accurately identify the position and status of the tunnel boring machine, adjust its own position in time, and achieve precise following. For example, in deep mining, the mine is dark and dusty, and the visual conditions are extremely poor. However, through the positioning information provided by the first radar sensing structure, the follow-up dust collection device can accurately follow the tunnel boring machine, remove dust in time, and provide workers with a clear working line of sight, reducing operational errors caused by unclear vision, and improving operational efficiency and safety. At the same time, the first visual detection structure can provide more intuitive and accurate location information under good visibility conditions, and the dual recognition mechanism ensures the reliable operation of the equipment in any environment.

[0035] The second recognition structure can also detect the moving direction, that is, the second recognition structure can detect the backward direction of the vehicle body.

[0036] like Figure 1 and Figure 2As shown, in this embodiment, the follow-up dust suction device of the tunnel boring machine also includes a first explosion-proof box 40 and a second explosion-proof box, the first visual detection structure and the first radar sensing structure are both arranged in the first explosion-proof box 40, the second visual detection structure, the second radar sensing structure and the controller are all arranged in the second explosion-proof box, the first explosion-proof box 40 is provided with a first opening, the first opening is provided with a first explosion-proof glass 41, the sensing part of the first visual detection structure and the sensing part of the first radar sensing structure both correspond to the first opening, the second explosion-proof box is provided with a second opening, the sensing part of the second visual detection structure and the sensing part of the second radar sensing structure both correspond to the second opening, and the second opening is provided with a second explosion-proof glass. The first explosion-proof box 40 and the second explosion-proof box and the first explosion-proof glass 41 and the second explosion-proof glass are arranged to ensure the safe operation of the equipment in an inflammable and explosive environment, prevent the electrical equipment from generating sparks and causing explosions, and at the same time protect the first identification structure and the second identification structure from being affected by the external environment, thereby improving the stability and reliability of the equipment. It is suitable for tunneling operations in inflammable and explosive environments such as coal mines, oil and gas fields, and can effectively improve operation safety.

[0037] Specifically, in flammable and explosive environments such as coal mines and oil and gas fields, the explosion-proof performance of the equipment is crucial. By setting the first explosion-proof box 40 and the second explosion-proof box and the first explosion-proof glass 41 and the second explosion-proof glass, the follow-up dust suction device of the tunnel boring machine can operate safely in a dangerous environment, which not only prevents the explosion caused by the sparks generated by the electrical equipment, but also protects the first identification structure and the second identification structure from interference from the external environment, ensuring the stability and reliability of the equipment. For example, in oil and gas field exploitation, the equipment needs to operate in an environment containing a large amount of flammable gas. Once a spark is generated, it is very easy to cause an explosion. The explosion-proof design of the follow-up dust suction device can effectively avoid this risk. At the same time, the explosion-proof box and explosion-proof glass can also protect the precision components inside the equipment, extend the service life of the equipment, reduce maintenance costs, and improve operating efficiency.

[0038] It should be noted that the second explosion-proof box is not shown in the figure.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the follow-up dust suction device of the tunnel boring machine also includes a first cleaning structure 50 and a second cleaning structure. The first cleaning structure 50 is arranged at the first explosion-proof glass 41, and the second cleaning structure is arranged at the second explosion-proof glass. The arrangement of the first cleaning structure 50 and the second cleaning structure can regularly clean the dust and stains on the first explosion-proof glass 41 and the second explosion-proof glass, maintain a clear field of view of the first identification structure and the second identification structure, improve the identification accuracy, and ensure the normal operation of the equipment. It is suitable for tunneling operations such as mines and tunnels that work in harsh environments for a long time, and can effectively improve the maintenance efficiency and identification effect of the equipment.

[0040] It should be noted that by setting up the first cleaning structure 50 and the second cleaning structure, the tunnel boring machine's follow-up dust suction device can automatically clean the first explosion-proof glass 41 and the second explosion-proof glass, maintaining a clear field of view for the first visual detection structure and the second visual detection structure, which is the key to the long-term stable operation of the equipment in harsh environments.

[0041] During long-term excavation operations, a large amount of dust and stains will accumulate on the surface of the first explosion-proof glass 41 and the second explosion-proof glass, affecting the recognition accuracy of the first visual detection structure and the second visual detection structure, thereby reducing the following efficiency of the equipment. Regular cleaning of the first cleaning structure 50 and the second cleaning structure can ensure a clear field of view for the first recognition structure and the second recognition structure, improve the recognition accuracy and following efficiency of the equipment, reduce maintenance workload, reduce maintenance costs, and improve the operating efficiency and stability of the equipment. Especially in tunnel excavation, the equipment needs to work in a closed environment for a long time, and the role of the first cleaning structure 50 and the second cleaning structure is more obvious, which can effectively prevent the recognition structure from malfunctioning due to dust obstruction and ensure the continuous and stable operation of the equipment.

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, the first cleaning structure 50 includes a cleaning pipe 51 and a plurality of nozzles 52, the cleaning pipe 51 is fixed on the first explosion-proof box 40, the plurality of nozzles 52 are connected to the cleaning pipe 51, the plurality of nozzles 52 are directed toward the first explosion-proof glass 41, and the spraying directions of the plurality of nozzles 52 are cross-set. Through the cross-spraying of the plurality of nozzles 52, the first explosion-proof glass 41 can be cleaned comprehensively and evenly, the cleaning efficiency and cleaning effect are improved, and a clear view of the first identification structure is ensured. It is suitable for excavation operations with a lot of dust such as mines and tunnels, and can effectively improve the recognition accuracy and operation efficiency of the equipment.

[0043] Specifically, the cross-spray design of multiple nozzles 52 makes the cleaning process more comprehensive and uniform, and the dust and stains on the surface of the first explosion-proof glass 41 can be completely removed, thereby improving the recognition accuracy of the equipment. For example, in a dusty mine, dust is likely to accumulate quickly on the surface of the first explosion-proof glass 41, affecting the normal operation of the first visual detection structure. In addition, the cross-set nozzles 52 can form a dense cleaning water curtain, which fully covers the surface of the first explosion-proof glass, ensures the cleanliness of the surface of the first explosion-proof glass, and maintains the recognition accuracy of the equipment even in an environment with high dust concentration, thereby improving operating efficiency. At the same time, the automation of the cleaning process reduces manual intervention, reduces maintenance workload, and improves the intelligence level of the equipment.

[0044] like Figure 1 as well as Figures 3 to 5As shown, in this embodiment, the dust collecting structure 20 includes a dust collecting cylinder 22, and a fan 23 is arranged in the dust collecting cylinder 22. The arrangement of the dust collecting cylinder 22 and the fan 23 can effectively collect and transport the dust generated during the excavation process, reduce the diffusion of dust in the working environment, improve the working environment, and protect the health of workers. It is suitable for excavation operations in closed or semi-closed spaces such as various mines and tunnels, and can effectively improve the cleanliness of the working environment and the health level of workers.

[0045] The efficient combination of the dust collection cylinder 22 and the fan 23 enables the follow-up dust collection device of the tunnel boring machine to quickly and effectively collect and transport dust, reducing the retention and diffusion of dust in the working environment, significantly improving the air quality of the working environment, and protecting the health of workers. For example, in coal mine excavation operations, dust is one of the main factors affecting the health of workers. The effective operation of the dust collection cylinder 22 and the fan 23 can remove dust in time, reduce dust concentration, reduce the chance of workers inhaling dust, and protect the health of workers. At the same time, it can also reduce the wear of dust on equipment, extend the service life of equipment, and reduce maintenance costs. In tunnel excavation, dust will also affect the vision and health of workers. The efficient dust collection ability of the follow-up dust collection device can create a cleaner and safer working environment for workers and improve work efficiency and safety.

[0046] like Figure 1 as well as Figures 3 to 5 As shown, in this embodiment, the follow-up dust suction device of the tunnel boring machine also includes a second driving member, the dust suction port structure 21 includes a conical cylinder 211, the conical cylinder 211 is located inside the dust suction cylinder 22, the second driving member is arranged between the conical cylinder 211 and the dust suction cylinder 22, and the second driving member drives the conical cylinder 211 to adjust the direction of the conical cylinder 211. Through the drive of the second driving member, the direction of the dust suction port can be flexibly adjusted, the adaptability of the equipment to different working directions is improved, and the dust suction effect is ensured. It is suitable for tunneling operations with variable working directions such as mines and tunnels, and can effectively improve the dust suction efficiency and working flexibility of the equipment.

[0047] Specifically, the provision of the second driving member enables the follow-up dust suction device of the tunnel boring machine to flexibly adjust the direction of the dust suction port according to the working direction of the tunnel boring machine, thereby improving the dust suction efficiency and operational flexibility of the equipment. For example, in tunnel excavation, the excavation direction may change according to geological conditions. The follow-up dust suction device of the tunnel boring machine can instantly adjust the direction of the dust suction port through the drive of the second driving member to ensure the dust suction effect, thereby improving the adaptability and flexibility of the equipment. In coal mine excavation, due to the complexity of the coal seam, the excavation direction often needs to be adjusted. The flexible adjustment ability of the follow-up dust suction device can ensure that the dust suction port is always aimed at the dust source, thereby improving the dust collection efficiency and reducing the harm of dust to workers' health.

[0048] like Figures 3 to 6As shown, in this embodiment, the follow-up dust suction device of the tunnel boring machine also includes a transmission structure 60, which includes a gear member 61 and a spherical gear 62. The gear member 61 is sleeved on the outer periphery of the conical cylinder 211, and the second driving member is drivingly connected to the spherical gear 62, and the spherical gear 62 is meshed with the gear member 61. Through the transmission of the gear member 61 and the spherical gear 62, the direction of the dust suction port structure 21 is precisely controlled, and the automation and intelligence level of the equipment is improved. It is suitable for tunneling operations such as mines and tunnels that require precise control of the direction of the dust suction port, and can effectively improve the dust suction efficiency and operation accuracy of the equipment.

[0049] Specifically, by adopting the transmission structure of the gear part 61 and the spherical gear 62, the follow-up dust suction device of the tunnel boring machine can realize the precise control of the direction of the dust suction port structure 21, thereby improving the automation and intelligence level of the equipment. For example, in tunnel excavation under complex geological conditions, the working direction of the tunnel boring machine may need to be adjusted frequently. Through the transmission of the gear part 61 and the spherical gear 62, the follow-up dust suction device of the tunnel boring machine can quickly and accurately adjust the direction of the dust suction port to ensure the dust suction effect, thereby improving the operation accuracy and flexibility of the equipment. In coal mining, due to the inclination and curvature of the coal seam, the excavation direction will also change. The precise control capability of the follow-up dust suction device of the tunnel boring machine can ensure that the dust suction port is always aimed at the dust source, thereby improving the dust collection efficiency and reducing the harm of dust to the health of workers. At the same time, it also improves the intelligence level of the equipment, reduces manual intervention, reduces maintenance costs, and improves operation efficiency and safety.

[0050] like Figures 3 to 6 As shown, in this embodiment, the conical barrel 211 includes a plurality of sector surfaces 2111 and a plurality of flexible connection surfaces 2112, and a flexible connection surface 2112 is connected between any two adjacent sector surfaces 2111. The follow-up dust suction device of the tunnel boring machine also includes a plurality of third driving members 70, and one sector surface 2111 of any two adjacent sector surfaces 2111 is drivingly connected to a third driving member 70, and the third driving member 70 can drive the sector surface 2111 to move to change the opening area of ​​the conical barrel 211. Through the drive of the plurality of third driving members 70, the opening area of ​​the conical barrel 211 can be flexibly adjusted, thereby improving the adaptability of the equipment to different dust amounts and ensuring the dust suction effect. It is suitable for tunneling operations such as mines and tunnels where the dust amount varies greatly, and can effectively improve the dust suction efficiency and operation flexibility of the equipment.

[0051] By setting a plurality of third driving members 70, the follow-up dust suction device of the tunnel boring machine can flexibly adjust the opening area of ​​the conical cylinder according to the change of the dust amount, thereby improving the dust suction efficiency and operation flexibility of the equipment. For example, in coal mining, due to the differences in coal quality and mining methods of different coal seams, the dust amount may vary significantly. The follow-up dust suction device of the tunnel boring machine can adapt to different dust amounts by adjusting the opening area of ​​the conical cylinder 211, ensure the dust suction effect, improve the dust collection efficiency, and reduce the harm of dust to workers' health. In tunnel excavation, due to the complexity of geological conditions, the dust amount will also fluctuate greatly. The flexible adjustment ability of the follow-up dust suction device of the tunnel boring machine can ensure that the dust suction port is always aimed at the dust source, improve the dust collection efficiency, reduce the harm of dust to workers' vision and health, and also improve the adaptability and flexibility of the equipment.

[0052] The tunnel boring machine follow-up dust collection device of the present application realizes efficient collection of dust generated during tunnel boring machine operation through the cooperation of the walking wheel 11, the dust collection structure 20, the first identification structure, the controller and the collection structure.

[0054] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0055] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0056] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
