DETAILED DESCRIPTION

[0024] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be an internal connection between two elements or an interaction relationship between two elements; for ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to the specific circumstances.

[0028] See also Figure 1-Figure 3 The dust-proof net device 100 for the entire section of a mine tunnel provided in the present invention comprises an automatic cart 1, a mounting frame 2, a connecting pipe 3, a dust-proof net 4 and a spray assembly 5; wherein the automatic cart 1 is configured to be movable along a first direction, where the first direction may be the length direction of the mine tunnel; the mounting frame 2 is mounted on the automatic cart 1; a connecting pipe 3 is arranged on the top of the mounting frame 2 along a second direction; the length of the connecting pipe 3 is suitable for matching the width of the mine tunnel; the dust-proof net 4 is connected to the bottom of the connecting pipe 3 to block dust in the mine tunnel; the spray assembly 5 is mounted on the connecting pipe 3 to spray toward the dust-proof net 4.

[0029] Through the above technical solution, the dustproof net 4 is connected to the bottom of the connecting pipe 3, the connecting pipe 3 is arranged on the top of the mounting frame 2 along the second direction, and the mounting frame 2 is set on the automatic cart 1. When the automatic cart 1 moves along the first direction, it drives the dustproof net device 100 to move along the first direction as a whole, avoiding the high labor intensity, low efficiency and safety hazards of manually moving the dustproof net device 100, and realizing the self-movement of the dustproof net device 100.

[0030] Here, it can be understood that the height of the mounting frame 2 can be the same as the height of the mine tunnel. In addition, the length of the connecting pipe 3 is the same as the width of the mine tunnel. In this way, dust protection for the entire section of the mine tunnel can be achieved. At the same time, the spray assembly 5 is installed on the connecting pipe 3 and sprays toward the dustproof net 4. The spray combines with the dust in the air to settle the dust, reduce the dust concentration in the air, and improve the dust prevention effect on the mine tunnel.

[0031] It can be understood that the full section of a mine tunnel refers to the complete section perpendicular to the center line of the mine tunnel, that is, the entire part of the mine tunnel in the cross section.

[0032] In addition, it can be understood that the automatic cart 1 can adopt a suitable commercially available cart that can be controlled and moved by itself. The present disclosure does not limit its specific structure, and its working principle is well known to those skilled in the art and will not be repeated here.

[0033] In order to facilitate the storage of the dustproof net device 100, in one embodiment of the present disclosure, the mounting frame 2 can be configured to be rotatably connected to the automatic cart 1, and a rotating shaft is provided at the connection between the mounting frame 2 and the automatic cart 1. After the mounting frame 2 rotates a certain angle, it contacts the upper end surface of the automatic cart 1. The dustproof net 4 and the connecting pipe 3 are disassembled and placed on the automatic cart 1. In this way, the storage capacity and portability of the dustproof net device 100 are improved.

[0034] It should be noted that, in addition to the rotational connection in the above embodiment, the mounting frame 2 and the automatic pallet truck 1 may be fixedly connected or detachably connected, and the present disclosure does not limit this.

[0035] In order to facilitate the movement of the dustproof net device 100, the automatic pallet 1 is arranged on any side of the bottom of the dustproof net 4 (such as Figure 1 As shown), with such arrangement, when the automatic trolley 1 moves in the first direction, it is convenient to avoid other equipment in the mine tunnel.

[0036] In order to adapt to different widths of locations in different mine tunnels, in the present disclosure, as Figure 1 and Figure 2 As shown, the connecting tube 3 is configured as a telescopic tube that can be telescoped along the second direction, and a plurality of insertion holes 31 for bolt fixing are formed on the telescopic tube.

[0037] Since the width of the mine tunnel is not constant, the connecting pipe 3 is configured to be able to extend and retract along the second direction and is fixed by inserting a pin into the socket 31 on the connecting pipe 3. In this way, on the one hand, the dustproof net 4 can adapt to positions of different widths in the mine tunnel. On the other hand, when the protective net device needs to be stored, the space occupancy rate of the protective net device can be reduced by adjusting the width of the connecting pipe 3, thereby improving the portability of the protective net device.

[0038] like Figure 1 and Figure 2 As shown, in order to facilitate the adjustment of the height of the dustproof net 4, in one embodiment of the present disclosure, the dustproof net device 100 may further include a driving member 6, the mounting frame 2 includes a supporting section 21 and a telescopic section 22, the supporting section 21 is connected to the automatic trolley 1, the two ends of the telescopic section 22 are respectively connected to the supporting section 21 and the connecting pipe 3, and the end of the telescopic section 22 connected to the connecting pipe 3 is constructed to be able to move telescopically along a third direction, and the driving member 6 is arranged between the supporting section 21 and the connecting pipe 3, and is used to drive the telescopic section 22 to retract, wherein the third direction is the same as the height direction of the mine tunnel.

[0039] One end of the telescopic section 22 is connected to the supporting section 21, and the other end is connected to the connecting pipe 3, and is constructed to be able to move along the third direction. The two ends of the driving member 6 are respectively connected to the connecting pipe 3 and the supporting section 21. The telescopic section 22 is driven to extend and retract by the driving member 6, so as to change the height of the connecting pipe 3, thereby driving the height change of the dustproof net 4. In this way, on the one hand, the dustproof net device 100 can cover the entire cross-section of the mine tunnel and improve the dustproof effect. On the other hand, the height of the dustproof net 4 can be adjusted by the driving member 6, which can effectively control the adjustment accuracy and improve the adjustment efficiency. On the other hand, it avoids the safety hazards caused by manually adjusting the dustproof net 4 at a high place and reduces the labor intensity.

[0040] like Figure 1 As shown, when the automatic cart 1 is set on any side of the bottom of the dustproof net 4, the mounting frame 2 is also set on one side of the dustproof net 4, and the telescopic section 22 of the mounting frame 2 is connected to one end of the connecting pipe 3, and the center of gravity of the connecting pipe 3 is close to the end away from the mounting frame 2. In order to improve the stability of the telescopic section 22 when telescoping, a counterweight block 32 is provided at the end of the connecting pipe 3 close to the mounting frame 2.

[0041] like Figure 1 and Figure 2 As shown, in one embodiment of the present disclosure, the telescopic section 22 may include a sleeve 221 and a telescopic rod 222 connected in a sleeve-type manner, the sleeve 221 is connected to the support section 21, and one end of the telescopic rod 222 away from the sleeve 221 is connected to the connecting pipe 3, and the telescopic rod 222 is configured to be able to telescope along the third direction. In this configuration, the height adjustment of the connecting pipe 3 is achieved through the sleeve-type cooperation of the sleeve 221 and the telescopic rod 222. At the same time, the sleeve 221 and the telescopic rod 222 connected in a sleeve-type manner have a simple structure, low cost and are easy to replace.

[0042] like Figure 1 As shown, in one embodiment of the present disclosure, the driving member 6 may include a telescopic oil cylinder 61 and a control valve 62, the piston rod 611 of the telescopic oil cylinder 61 is connected to the connecting pipe 3, and the control valve 62 is electrically connected to the telescopic oil cylinder 61, and is used to control the extension and retraction of the piston rod 611 of the telescopic oil cylinder 61. The piston rod 611 of the telescopic oil cylinder 61 is connected to the connecting pipe 3, and the control valve 62 controls the extension and retraction of the piston rod 611, thereby driving the connecting pipe 3 to extend and retract along the third direction, so as to adjust the height of the dustproof net 4.

[0043] It is understandable that the driving member 6 can also drive the telescopic section 22 to extend and retract in an electric or pneumatic manner, such as an electric telescopic rod 222 and a motor, which is not limited in the present disclosure.

[0044] like Figure 1 and Figure 2As shown, in the present disclosure, the dustproof net device 100 may further include a retractable net assembly 7, which may include a traction rope 71, one end of which is connected to the bottom of the dustproof net 4, and the other end of which is constructed as an operating end 711, which is configured to be able to fold the dustproof net 4 in the height direction of the dustproof net device 100 when pulled.

[0045] When the staff needs to pass through the dust net 4 or avoid the equipment in the mine tunnel, the dust net 4 can be retracted in the height direction of the dust net device 100 by pulling the operating end 711, thereby improving the convenience and passing performance of the dust net device 100. In addition, the traction rope 71 is provided to improve the storage capacity of the dust net 4.

[0046] It should be noted that the present disclosure does not limit the specific position and number of the traction ropes 71 .

[0047] like Figure 1 As shown, in one embodiment of the present disclosure, the net collecting and releasing assembly 7 may further include a pulley 72 and a hydraulic motor 73, the pulley 72 is arranged on the connecting pipe 3, the traction rope 71 is wound around the pulley 72, the hydraulic motor 73 is installed on the automatic cart 1 and is connected to the operating end 711 of the traction rope 71, and the hydraulic motor 73 is used to control the traction rope 71 to collect or release the net.

[0048] The pulley 72 is arranged on the connecting pipe 3, and the traction rope 71 is wound around the pulley 72. Such an arrangement is conducive to pulling the traction rope 71. In addition, the hydraulic motor 73 is connected to the operating end 711 of the traction rope 71. In this way, the hydraulic motor 73 is controlled to control the traction rope 71 to collect or release the net, thereby reducing the intensity of manual labor and facilitating the precise control of the folding height and lowering height of the protective net.

[0049] In the present disclosure, the number of pulleys 72 can be four, wherein three pulleys 72 are arranged on the connecting pipe 3 at intervals along the length direction of the connecting pipe 3. In this way, the two sides of the protective net are ensured to be balanced when the net is retracted and released, and the efficiency of retracting and releasing the net is improved.

[0050] In other embodiments, the number and position of the pulleys 72 may also be set to other numbers and positions suitable for retracting and releasing the net, which is not limited in the present disclosure.

[0051] In order to ensure the dustproof net 4 covers the entire section of the mine tunnel, Figure 1-Figure 3 As shown, a plurality of counterweight rods 41 are provided on the dustproof net 4. In this way, on the one hand, a gap between the dustproof net 4 and the entire cross section of the mine tunnel due to external factors such as wind is avoided, and on the other hand, the flatness of the dustproof net 4 can be improved by providing the counterweight rods 41, making the dustproof net device 100 more beautiful.

[0052] In one embodiment of the present disclosure, Figure 1-Figure 3 As shown, the spray assembly 5 may include a spray nozzle 51 and a water pump 52. The water pump 52 is installed on the automatic pallet truck 1 and connected to the spray nozzle 51 through a pipeline. The spray nozzle 51 is installed on the connecting pipe 3 and is used to spray toward the dustproof net 4. By arranging the spray nozzle 51 on the connecting pipe 3, the spray nozzle 51 sprays toward the dustproof net 4, and the water mist combines with the dust in the air, so that the dust settles and is captured by the dustproof net 4, thereby improving the dustproof effect.

[0053] In other embodiments, the spray nozzle 51 may be configured as an angle-adjustable spray nozzle 51 , and the dust prevention effect may be improved by adjusting the angle of the spray nozzle 51 .

[0054] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
