Description

Technical Field

[0001] This invention relates to the field of dust control technology in coal mines, and more specifically, to a dust collection device for a tunneling machine. Background Technology

[0002] In conventional roadheaders, the dust removal fan at the face is installed on a single track and connected to the tail of the roadheader via a connecting rod. Therefore, when the roadheader moves forward or backward, it needs to move the dust removal fan back and forth on the track. Due to the unevenness of the tail pull and the undulating roadway conditions, the track is not straight or level, making it very easy for the dust removal fan to derail or even overturn. This directly affects the normal operation of the dust removal fan, posing a great safety hazard. It also affects the roadheader construction and is detrimental to production.

[0003] In the prior art, such as Chinese Patent Publication No. CN208619149U, a dust removal system for rapid movement at the face of a roadheader in a rock tunnel is disclosed. This system includes a track device and a dust removal device. The track device includes a slide rail and a sliding rod. The slide rail is fixed to the top wall of the rock tunnel along its direction. A carrying trolley is located at the end of the slide rail away from the tunnel face, and the carrying trolley can slide along the slide rail. The carrying trolley is connected to a power device. The sliding rod is located on the side of the carrying trolley closest to the tunnel face and is connected to the slide rail via pulleys. The dust removal device includes a dust removal fan connected to the carrying trolley. The air inlet of the dust removal fan faces the tunnel face, and a frame duct is connected to this air inlet. The frame duct is connected to the sliding rod. Although the dust removal fan achieves synchronous movement with the frame duct through the drive of the carrying trolley, it eliminates the safety hazard of derailment during rapid movement, saves manpower and resources, and improves the dust control effect of the roadheader. However, it is essentially installed by hoisting, which makes the track installation difficult. The movement of the dust collector fan can also pose safety hazards. Furthermore, its movement is highly dependent on the track, which limits its application scenarios and makes it difficult to meet the trend of automated control. Summary of the Invention

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

At the same time, it should be understood that the dimensions of the various parts shown in the drawings are not drawn to actual scale for ease of illustration. Techniques, methods, and equipment known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered part of the specification where appropriate. In all examples shown and discussed herein, any specific value should be interpreted as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments can have different values. It should be noted that like reference numerals and letters refer to like items in the following drawings, and thus, once an item is defined in one drawing, it need not be discussed further in subsequent drawings.

[0028] As Figure 1 shown in the embodiment, the tunneling machine following dust collection device includes a vehicle body 10, a dust collection structure 20, a first identification structure, a controller, and a collection structure. The vehicle body 10 has a walking wheel 11. The dust collection structure 20 is arranged on the vehicle body 10, and the first end of the dust collection structure 20 has a dust collection 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 tunneling machine. The controller controls the start and stop of the walking wheel 11 according to the identification signal of the first identification structure. The collection structure is arranged at the second end of the dust collection structure 20. Among them, the orientation of the dust collection port structure 21 is adjustably arranged.

[0029] The technical scheme of the embodiment is applied, the dust collection structure 20 and the first identification structure are arranged on the vehicle body 10, the vehicle body 10 has the walking wheel 11, so that the vehicle body 10 can move. The dust collection structure 20 can realize dust collection through the dust collection port structure 21. The first identification structure can detect the distance from the tunneling machine and can transmit the detected signal to the controller, and the controller can control the start and stop of the walking wheel 11 according to the identification signal, so that the vehicle body 10 can follow the tunneling machine to move. The collection structure can collect smoke dust. Through the above arrangement, the vehicle body 10 can move synchronously with the tunneling machine, so that the dust collection effect of the dust collection structure 20 is better, and since the angle of the dust collection port structure 21 is adjustably arranged, it can be adjusted according to the direction of the smoke dust, thereby improving the dust collection effect. Due to the action of the walking 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 limited. Therefore, the technical scheme of the embodiment effectively solves the problem that the moving direction of the dust removal fan in the related art depends on the track, thereby limiting the application scene.

[0030] In practical applications, the follow-up dust suction device can significantly reduce the dust concentration inside the mine and tunnel, improve the working conditions of workers, and reduce the incidence of respiratory diseases. For example, in coal mining, dust control is crucial because coal dust not only affects visibility but also can cause explosions. The follow-up dust suction device can follow the roadheader and immediately remove dust, effectively reducing the risk of explosion and improving work safety. In tunnel construction, dust also affects worker health and construction progress. The application of the follow-up dust suction device can improve air quality, reduce the opportunity for workers to inhale harmful dust, and improve construction efficiency and quality.

[0031] As Figure 1 In this embodiment, the roadheader follow-up dust suction device further 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, and 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 is in supporting cooperation with the ground. 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 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 terrain such as mines and tunnels, which can effectively prevent the equipment from sliding or falling in a non-working state.

[0032] Specifically, by setting the parking bracket 30, the stability of the roadheader follow-up dust suction device in the working state is significantly enhanced, avoiding the sliding or falling of the equipment due to uneven or inclined ground, reducing the risk of equipment damage, and also reducing the 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, inclined or potholed. The equipment can be stably stored, enhancing the flexibility and safety of the operation. For example, in the inclined shaft operation of a coal mine, the ground is inclined, and the parking bracket can provide additional support to ensure the stability of the equipment and prevent the equipment from sliding, providing a stable foundation for dust suction operations.

[0033] As Figure 1As shown, in the present embodiment, the first recognition structure includes a first visual detection structure and a first radar sensing structure, which are arranged at the first end of the vehicle body 10; the tunneling machine following dust collection device further includes a second recognition structure, which includes a second visual detection structure and a second radar sensing structure, arranged at the second end of the vehicle body 10. Through the dual recognition of the first visual detection structure and the first radar sensing structure and the second visual detection structure, the detection accuracy of the first recognition structure on the position and state of the tunneling machine is improved, ensuring that the tunneling machine following dust collection device can accurately and timely follow the movement of the tunneling machine, especially in low visibility environments, the first radar sensing structure can provide reliable positioning information. It is suitable for low visibility, complex environment, such as mine, tunnel and other tunneling operations, which 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 significantly improves the positioning accuracy and environmental adaptability of the tunneling machine following dust collection device, even in extremely low visibility environments, the position and state of the tunneling machine can be accurately identified, and the position can be adjusted in time to achieve precise following. For example, in deep mining, the inside of the mine is dark and dusty, and the visibility is extremely poor, but through the positioning information provided by the first radar sensing structure, the tunneling machine following dust collection device can accurately and accurately follow the tunneling machine and timely remove dust, providing workers with a clear line of sight, reducing the operation error caused by unclear vision, and improving the operation efficiency and safety. At the same time, the first visual detection structure can provide more intuitive and accurate position information in good visibility, and the dual recognition mechanism ensures reliable operation of the equipment in any environment.

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

[0036] For example, Figure 1 and Figure 2As shown, in this embodiment, the tunneling machine following dust suction device further comprises 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 arrangement of 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 ensures the safe operation of the equipment in the flammable and explosive environment, prevents the explosion caused by the spark of the electrical equipment, and protects the first identification structure and the second identification structure from the influence of the external environment, thereby improving the stability and reliability of the equipment. It is suitable for tunneling operation in flammable and explosive environments such as coal mines and oil and gas fields, and can effectively improve the operation safety.

[0037] Specifically, in the flammable and explosive environment such as coal mines and oil and gas fields, the explosion-proof performance of the equipment is crucial. By arranging 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 tunneling machine following dust suction device can safely operate in a dangerous environment, not only preventing explosions caused by sparks from electrical equipment, but also protecting the first identification structure and the second identification structure from external environmental interference, 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, and once a spark is generated, an explosion is extremely likely to occur. The explosion-proof design of the following dust suction device can effectively avoid such risks, and the explosion-proof box and the explosion-proof glass can also protect the delicate components inside the equipment, prolong the service life of the equipment, reduce maintenance costs, and improve operation efficiency.

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

[0039] As shown in Figure 1 and Figure 2 As shown, in this embodiment, the tunneling machine following dust suction device further comprises 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 periodically 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 in mines, tunnels and other environments 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 the first cleaning structure 50 and the second cleaning structure, the roadheader following dust collection device can automatically clean the first explosion-proof glass 41 and the second explosion-proof glass, maintain the clear view of the first visual detection structure and the second visual detection structure, which is the key to the stable operation of the equipment in harsh environments for a long time.

[0041] In long-term tunneling operation, the first explosion-proof glass 41 and the second explosion-proof glass surface will accumulate a lot of dust and stains, 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 view of the first recognition structure and the second recognition structure, improve the recognition accuracy and following efficiency of the equipment, reduce the maintenance workload, reduce the maintenance cost, and improve the operation efficiency and stability of the equipment. Especially in tunneling, the equipment needs to work in a closed environment for a long time, and the first cleaning structure 50 and the second cleaning structure play a more obvious role, which can effectively prevent the recognition structure from malfunctioning due to dust obstruction and ensure the continuous and stable operation of the equipment.

[0042] As shown in Figure 1 and Figure 2 In this embodiment, the first cleaning structure 50 includes a cleaning pipe 51 and a plurality of spray heads 52, the cleaning pipe 51 is fixed on the first explosion-proof box 40, the plurality of spray heads 52 are in communication with the cleaning pipe 51, the plurality of spray heads 52 are directed towards the first explosion-proof glass 41, and the spray directions of the plurality of spray heads 52 are crosswise arranged. Through the crosswise spraying of the plurality of spray heads 52, the first explosion-proof glass 41 can be comprehensively and uniformly cleaned, the cleaning efficiency and effect are improved, and the clear view of the first recognition structure is ensured. It is suitable for tunneling operations with more dust in mines, tunnels, etc., which can effectively improve the recognition accuracy and operation efficiency of the equipment.

[0043] Specifically, the crosswise spraying design of the plurality of spray heads 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, improving the recognition accuracy of the equipment. For example, in a mine with dust, the surface of the first explosion-proof glass 41 is prone to quickly accumulate dust, affecting the normal work of the first visual detection structure. And the crosswise arranged spray heads 52 can form a dense cleaning water curtain, comprehensively cover the surface of the first explosion-proof glass, and ensure the cleanliness of the surface of the first explosion-proof glass. Even in a high-dust-concentration environment, the recognition accuracy of the equipment can be maintained, and the operation efficiency can be improved. At the same time, the automation of the cleaning process reduces the manual intervention, reduces the maintenance workload, and improves the intelligent level of the equipment.

[0044] As shown in Figure 1 and Figures 3 to 5As shown, in this embodiment, the dust collection structure 20 includes a dust collection cylinder 22, and a fan 23 is arranged inside the dust collection cylinder 22. The arrangement of the dust collection cylinder 22 and the fan 23 can effectively collect and transport the dust generated during the tunneling process, reduce the spread of dust in the working environment, improve the working environment, and protect the health of workers. It is suitable for tunneling operations in various mines, tunnels and other closed or semi-closed spaces, 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 tunneling machine to quickly and effectively collect and transport dust, reducing the residence and spread 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 tunneling 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 timely remove dust, reduce dust concentration, reduce the opportunity for workers to inhale dust, and protect the health of workers. At the same time, it can also reduce the wear and tear of equipment caused by dust, prolong the service life of equipment, and reduce maintenance costs. In tunneling, dust can also affect the visibility and health of workers. The efficient dust collection capability of the dust collection device can create a cleaner and safer working environment for workers, improving work efficiency and safety.

[0046] As shown in the Figure 1 and Figures 3 to 5 As shown in this embodiment, the tunneling machine dust collection device also includes a second driving member, and the dust collection port structure 21 includes a conical cylinder 211 located inside the dust collection cylinder 22. The second driving member is arranged between the conical cylinder 211 and the dust collection cylinder 22, and drives the conical cylinder 211 to adjust the orientation of the conical cylinder 211. Through the driving of the second driving member, the orientation of the dust collection port can be flexibly adjusted, improving the adaptability of the equipment to different working directions and ensuring the dust collection effect. It is suitable for tunneling operations with variable working directions in mines, tunnels and other environments, and can effectively improve the dust collection efficiency of the equipment and the flexibility of the operation.

[0047] Specifically, the arrangement of the second driving member enables the tunneling machine dust collection device to flexibly adjust the orientation of the dust collection port according to the working direction of the tunneling machine, improving the dust collection efficiency and flexibility of the equipment. For example, in tunneling, the tunneling direction may vary depending on geological conditions. The tunneling machine dust collection device can adjust the orientation of the dust collection port in real time through the driving of the second driving member, ensuring the dust collection effect and improving the adaptability and flexibility of the equipment. In coal mine tunneling, due to the complexity of coal seams, the tunneling direction also often needs to be adjusted. The flexible adjustment capability of the dust collection device can ensure that the dust collection port is always aligned with the dust source, improving the dust collection efficiency and reducing the harm of dust to workers' health.

[0048] As shown in the Figures 3 to 6As shown, in this embodiment, the tunneling machine following dust suction device further 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, the second driving member is drivingly connected with the spherical gear 62, and the spherical gear 62 is meshingly arranged with the gear member 61. Through the transmission of the gear member 61 and the spherical gear 62, the accurate control of the orientation of the dust suction port structure 21 is realized, and the automation and intelligent level of the equipment are improved. It is suitable for mining, tunneling and other tunneling operations that require accurate control of the orientation of the dust suction port, and can effectively improve the dust suction efficiency and operation precision of the equipment.

[0049] Specifically, by adopting the transmission structure of the gear member 61 and the spherical gear 62, the tunneling machine following dust suction device can realize accurate control of the orientation of the dust suction port structure 21, and improve the automation and intelligent level of the equipment. For example, in the tunneling under complex geological conditions, the working direction of the tunneling machine may need to be adjusted frequently. Through the transmission of the gear member 61 and the spherical gear 62, the tunneling machine following dust suction device can quickly and accurately adjust the orientation of the dust suction port, ensure the dust suction effect, and improve the operation precision and flexibility of the equipment. In coal mining, due to the inclination and bending of the coal seam, the tunneling direction will also change. The accurate control capability of the tunneling machine following dust suction device can ensure that the dust suction port is always aligned with the dust source, improve the dust collection efficiency, reduce the harm of dust to workers' health, and also improve the intelligent level of the equipment, reduce manual intervention, reduce maintenance cost, and improve operation efficiency and safety.

[0050] As shown, Figures 3 to 6 As shown, in this embodiment, the conical cylinder 211 includes a plurality of fan-shaped surfaces 2111 and a plurality of flexible connecting surfaces 2112, and one flexible connecting surface 2112 is connected between any two adjacent fan-shaped surfaces 2111. The tunneling machine following dust suction device further includes a plurality of third driving members 70, one fan-shaped surface 2111 in any two adjacent fan-shaped surfaces 2111 is drivingly connected with one third driving member 70, and the third driving member 70 can drive the fan-shaped surface 2111 to move to change the opening area of the conical cylinder 211. Through the driving of the plurality of third driving members 70, the opening area of the conical cylinder 211 can be flexibly adjusted, the adaptability of the equipment to different dust amounts is improved, and the dust suction effect is ensured. It is suitable for tunneling operations with large changes in dust amount in mines, tunnels and the like, and can effectively improve the dust suction efficiency and operation flexibility of the equipment.

[0051] By setting multiple third driving members 70, the roadheader following dust collection device can flexibly adjust the opening area of the conical cylinder according to the change of dust amount, improving the dust collection efficiency and operation flexibility of the equipment. For example, in coal mining, due to the difference in coal quality and mining method of different coal seams, the amount of dust may change significantly. The roadheader following dust collection device can adapt to different dust amounts by adjusting the opening area of the conical cylinder 211, ensuring the dust collection effect, improving the dust collection efficiency, and reducing the harm of dust to workers' health. In tunneling, due to the complexity of geological conditions, the amount of dust also fluctuates greatly. The flexible adjustment capability of the roadheader following dust collection device can ensure that the dust suction port is always aligned with the dust source, improving the dust collection efficiency, reducing the harm of dust to workers' vision and health, and improving the adaptability and flexibility of the equipment.

[0052] The roadheader following dust collection device of the present application, through the cooperation of the traveling wheels 11, the dust collection structure 20, the first identification structure, the controller and the collection structure, realizes efficient collection of dust generated during the operation of the roadheader. At the same time, the orientation of the dust suction port structure 21 is adjustable, which can flexibly adjust the dust suction port according to the operation position and direction of the roadheader, improving the dust collection efficiency. The setting of the parking support 30 and the first cleaning structure 50 not only ensures the stability and safety of the equipment, but also ensures the cleanliness of the first identification structure, thereby improving the identification accuracy and further improving the automation and intelligence level of the equipment, which has significant benefits for improving the mine operation environment and protecting workers' health.

[0053] In summary, the roadheader following dust collection device of the present application, through its unique design and function, not only can effectively improve the working environment and reduce the harm of dust to workers' health, but also can improve the adaptability and reliability of the equipment, ensure the stable operation of the equipment in complex terrain and harsh environment, and further improve the efficiency and safety of the tunneling operation in closed or semi-closed spaces such as mines and tunnels. Especially in flammable and explosive environments such as coal mines and oil and gas fields, and in work scenes with large changes in dust amount, the excellent performance and effect of the device will be more significant, providing a safer and healthier working environment for workers, and providing strong technical support for efficient tunneling in mines and tunnels. In practical application, the following dust collection device not only reduces the impact of dust on workers' health, improves the efficiency and safety of the operation, but also reduces the need for manual intervention through its intelligent design, reduces the labor intensity of workers, and improves the intelligent level of the operation, providing strong technical support for efficient, safe and intelligent operation in mines and tunnels.

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

[0056] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
