[0001] This invention relates to the field of tunnel support technology, specifically to a network support auxiliary system, a tunneling machine including the system, and a network support method. Background Technology
[0002] Mesh support is an essential technology for underground tunneling faces. The main methods for supporting the roof of tunnels are to lay metal mesh and install anchor bolts to stabilize the surrounding rock of the tunnels and ensure the safety of underground workers. Mesh support is currently the most commonly used support method. However, traditional mesh support operations rely on manual labor for handling and installation. Since the mesh is typically made of steel wire mesh, a single mesh panel is very heavy. Underground workers usually need two people to lift and install it, making the labor intensity extremely high. Furthermore, the working space on the tunneling machine is limited, making operation difficult and posing safety hazards. Summary of the Invention

In the Internet access support system described above, optionally, a net expansion device is provided between the lifting platform and the Internet access device. The net expansion device is used to spread the net from both sides to adjust the curvature of the net. A first transport device is provided between the net expanding device and the lifting platform. The first transport device is used to transport the net from the lifting platform to the net expanding device. A second transport device is provided between the network expansion device and the internet access device, and the second transport device is used to transport the network sheet from the network expansion device to the internet access device.
[0005] In the aforementioned internet access support system, optionally, the network expansion device includes a first panel, a second panel, a third panel, a first hydraulic cylinder, a second hydraulic cylinder, and a first support base. The first panel and the third panel are respectively hinged to both sides of the second panel. The surface formed by the first panel, the second panel and the third panel is used to place the mesh. The first panel and the third panel can be folded with the hinge point with the second panel as the center. The first support base has two ends fixed to the second panel and the device, respectively. The two sides of the first support base are respectively provided with hinge ends that are hinged to one end of the first cylinder and one end of the second cylinder. The other end of the first cylinder is hinged to the first panel, and the other end of the second cylinder is hinged to the third panel. Thus, the first cylinder and the second cylinder can control the folding angle of the first panel and the third panel, respectively.
[0006] In the aforementioned internet access support system, optionally, the first transport device includes two first telescopic rods, which are respectively located on both sides of the second panel, and the two first telescopic rods can extend from the second panel to both sides of the lifting platform.
[0007] In the aforementioned Internet access support system, optionally, the Internet access device includes a fourth panel, a fifth panel, a sixth panel, and a second support base. The fourth panel and the sixth panel are respectively connected to both sides of the fifth panel, and the fourth panel, the fifth panel, and the sixth panel form a surface for placing the mesh. The two ends of the second support base are respectively fixed to the fifth panel and the device.
[0008] In the Internet access support system described above, optionally, the second support base is a telescopic device to lift the surfaces formed by the fourth panel, the fifth panel, and the sixth panel.
[0009] In the aforementioned Internet access support system, optionally, the second transport device includes two second telescopic rods, which are respectively located on the side of the fourth panel and the sixth panel away from the fifth panel, and the two second telescopic rods can extend from the sixth panel to both sides of the Internet expansion device.
[0010] In the aforementioned internet access support system, optionally, the second transport device further includes a chain moving device, which is arranged around the upper and lower surfaces of the second telescopic rod and is capable of rotating along the upper and lower surfaces of the second telescopic rod. The second telescopic rod is provided with a bracket 31, the bracket 31 having a recess 32, the recess 32 being used to hook the mesh to fix the mesh in the front-back direction.

[0012] To achieve the aforementioned objective, a third aspect of the present invention provides an internet access protection method, the method comprising an internet access protection auxiliary system as described in any one of the preceding second aspects, the method comprising the following steps: Step A: Place the mesh panel on the lifting platform, and raise the lifting platform to the same height as the internet access device; Step B: The transport device transports the mesh located on the lifting platform to the internet access device; Step C: The anchor bolt support device installs the mesh located on the meshing device onto the roof wall of the roadway to be supported.
[0013] The wire mesh support auxiliary system of the present invention includes a lifting platform, a wire mesh expansion device, and a wire mesh connection device, with a transport device provided between the lifting platform and the wire mesh expansion device, and between the wire mesh expansion device and the wire mesh connection device.

Therefore, they should not be construed as limitations on this disclosure.
[0020] Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first," "second," "third," or "fourth" may explicitly or implicitly include at least one of those features.
[0021] In the description of this disclosure, "multiple" means at least two, such as two, three or more, unless otherwise expressly and specifically limited.
[0022] Figure 1 This is a side view of an embodiment of the Internet access support system of the present invention.
[0023] from Figure 1 As can be seen from the embodiments, the network support auxiliary system 2 is installed on top of the equipment 1, which can be, but is not limited to, tunneling machines, shield tunneling machines, coal mining machines, or other equipment that can enter the roadway. In other embodiments, the network support auxiliary system 2 can also be installed on the roadway surface.
[0024] With the top wall of the tunnel as the upper part and the area in front of the wire mesh to be supported as the front, in one embodiment, the wire mesh support auxiliary system 2 includes, from back to front, a lifting platform 4 and a wire mesh device 8. The wire mesh device 8 is located below the top wall of the tunnel to be supported, and the lifting platform 4 is used to place the wire mesh 3 to be supported.
[0025] The lifting platform 4 is used to lift the mesh sheet 3 to at least the same height as the mesh-connecting device 8. A transportation device is also provided between the lifting platform 4 and the mesh-connecting device 8. The transportation device can transport the lifted mesh sheet 3 to the upper surface of the mesh-connecting device 8, and then the mesh sheet 3 can be fixed to the top wall of the roadway to be supported by the anchor drilling machine.
[0026] exist Figure 1 In one embodiment, the net support auxiliary system 2 has two lifting platforms 4 to increase the area supporting the net panel 3, thereby lifting the net panel 3 more stably. Optionally, the two lifting platforms 4 are arranged in parallel (e.g., Figure 2 As shown, to increase the area of the support mesh on both sides, the two lifting platforms 4 can also be arranged front and back to increase the area of the support mesh 3 in the front and back width. The number of lifting platforms 4 is unlimited; there can be one or more, depending on the actual situation, to increase the area of the support mesh 3.
[0027] Optionally, the transport device can be two telescopic rods, the distance between which is greater than the width of both sides of the lifting platform 4, so that the net sheet 3 can be lifted from both sides of the lifting platform 4 for transport. This transport device can be installed on the netting device 8, extending from the netting device 8 to both sides of the lifting platform 4 to lift the net sheet 3, and then retracting to transport it to the upper surface of the netting device 8. In other embodiments, the transport device can also be installed on the lifting platform 4, lifting the net sheet 3 from the lifting platform 4 and transporting it to the upper surface of the netting device 8. In other embodiments, the transport device can also be a transport trolley, a hanging mobile device, etc., as long as it can transport the net sheet 3.
[0028] The upper surface of the wire mesh device 8 can be an arc-shaped surface that matches the curvature of the roof wall to be wired in the tunnel. This arc-shaped surface can shape the wire mesh 3 so that the wire mesh 3 can better fit the roof wall to be wired in the tunnel.
[0029] Optionally, such as Figure 1 In one embodiment, the device 1 is a multi-head tunneling machine, and the network support device 8 can be located behind the shield of the upper cutting head device of the device 1, making full use of the space of the tunneling machine to make the network support auxiliary system simple and compact in structure.
[0030] It should be noted that the untreated wire mesh 3 is usually curled up. Therefore, a wire mesh expanding device 6 can be further provided between the lifting platform 4 and the wire mesh feeding device 8. The expanding device 6 is used to spread the wire mesh 3 from both sides to conform to the curvature of the roadway roof to be supported by the wire mesh. Since the distance of transporting the wire mesh 3 from the rear of the equipment to the wire mesh feeding device 8 is long, the expanding device 6 can also shorten the transport distance of the transport device in one trip, making the transport process smoother.
[0031] like Figure 1 As shown, a first transport device 5 is provided between the net-expanding device 6 and the lifting platform 4, and a second transport device 7 is provided between the net-expanding device 6 and the net-connecting device 8. The first transport device 5 can transport the net sheet 3 from the lifting platform 4 to the upper surface of the net-expanding device 6, whereby the net-expanding device 6 expands the net sheet 3. The second transport device 7 can transport the net sheet 3 from the net-expanding device 6 to the upper surface of the net-connecting device 8.
[0032] Furthermore, from Figure 1 It can also be seen that the mesh expansion device 6 and the mesh connection device 8 each include a first support base 66 and a second support base 84, which fix the mesh expansion device 6 and the mesh connection device 8 above the equipment 1, respectively. Furthermore, the first support base 66 and the second support base 84 can raise the mesh expansion device 6 and the mesh connection device 8, so that the mesh 3 is closer to the top of the roadway where it needs to be connected for support, facilitating subsequent mesh connection support operations.
[0033] Figure 2 This is a top-view perspective schematic diagram of an embodiment of the Internet access support system of the present invention.
[0034] exist Figure 2 In this embodiment, the mesh expanding device 6 further includes a first panel 61, a second panel 62, a third panel 63, a first hydraulic cylinder 67, and a second hydraulic cylinder 68. The second panel 62 is located in the middle, and the first panel 61 and the third panel 63 are located on both sides of the second panel 62, with gaps between them. The first panel 61 and the third panel 63 are respectively hinged to both sides of the second panel 62, and both the first panel 61 and the third panel 63 can be folded around the hinge point with the second panel 62 as the center. The mesh 3 can be placed on the surface formed by the first panel 61, the second panel 62, and the third panel 63. The two sides of the mesh 3 can be flipped upwards as the first panel 61 and the third panel 63 are folded, so that the mesh 3 is expanded and its curvature conforms to the shape of the roof wall to be supported by the mesh in the roadway.
[0035] Optionally, the first panel 61, the second panel 62, and the third panel 63 can be rigid panels as shown in the figure. Rigid panels have stronger supporting force to support the mesh 3 and make it easier to control the folding angle. In other embodiments, the first panel 61, the second panel 62, and the third panel 63 can also be integrally designed elastic panels. The sides of the elastic panel can also be opened to adjust the angle of the mesh 3 on it. After the mesh 3 is transported to the front, the force on the sides of the elastic panel can be released, and the elastic panel can return to its original shape.
[0036] As can also be seen from the figure, the top surfaces of the first panel 61, the second panel 62, and the third panel 63 of the mesh expanding device 6 are serrated. This serrated top surface design can increase the friction of the first panel 61, the second panel 62, and the third panel 63, so that the mesh 3 can be placed more stably on the surface formed by the first panel 61, the second panel 62, and the third panel 63 during the mesh expanding process, and will not slip off.
[0037] Specifically, as shown in the figure, the two ends of the first support base 66 are fixed to the top of the device 1 and the second panel 62 of the first support base 66, respectively, to support the second panel 62. The bottom of the first support base 66 has one end of the first hydraulic cylinder 67 and one end of the second hydraulic cylinder 68 on each side. The other ends of the first hydraulic cylinder 67 and the second hydraulic cylinder 68 are respectively connected to the first panel 61 and the third panel 63. Thus, the first hydraulic cylinder 67 and the second hydraulic cylinder 68 can control the angle at which the first panel 61 and the third panel 63 fold about the hinge point with the second panel 62, thereby controlling the arc of the mesh 3.
[0038] As shown in the embodiment, the first panel 61, the second panel 62, and the third panel 63 are all rectangular and have the same front-to-back longitudinal length. As can be seen from the figure, the mesh 3 can be laid on the curved surface formed by the first panel 61, the second panel 62, and the third panel 63. The front-to-back longitudinal length of the first panel 61, the second panel 62, and the third panel 63 can be greater than or equal to the front-to-back width of the mesh 3, thereby better supporting the various parts of the mesh 3 and allowing the mesh 3 to be more completely unfolded.
[0039] In other embodiments, the first panel 61, the second panel 62, and the third panel 63 may also be other shapes, such as circular, polygonal, wedge-shaped, etc., as long as they can support and stretch the mesh 3.
[0040] As can be clearly seen from the figure, the first transport device 5 includes two first telescopic rods 54 (such as...). Figure 4 As shown, the two first telescopic rods 54 are respectively located on both sides of the second panel 62, and the distance between the two first telescopic rods 54 is greater than the width of both sides of the lifting platform 4. This facilitates the first transport device 5 to extend from the second panel 62 to both sides of the lifting platform 4, receive the mesh 3 located on the lifting platform 4, and transport the mesh 3 from the lifting platform 4 to the mesh expanding device 6. Optionally, the two first telescopic rods 54 can be parallel to each other, which facilitates installation and allows for more stable transport of the mesh 3.
[0041] exist Figure 2 In this embodiment, the Internet access device 8 has the same structure as the Internet expansion device 6, also having three panels: a fourth panel 81, a fifth panel 82, and a sixth panel 83. The fifth panel 82 is located in the middle, and the fourth panel 81 and the sixth panel 83 are located on either side of the fifth panel 82, with gaps between them. The curvature formed by the fourth panel 81, the fifth panel 82, and the sixth panel 83 is the same as the curvature of the mesh 3 after the Internet expansion device 6 expands it. Furthermore, the fourth panel 81, the fifth panel 82, and the sixth panel 83 correspond one-to-one with the first panel 61, the second panel 62, and the third panel 63, respectively, to better support the mesh 3 and maintain the curvature of the mesh 3 after the Internet expansion device 6 expands it.
[0042] Optionally, in the embodiment shown in the figure, the fourth panel 81, the fifth panel 82, and the sixth panel 83 can be telescopic panels, which can be adjusted according to the size of the mesh 3, so that the mesh 3 can be placed more stably on the Internet device 8.
[0043] Furthermore, the second support base 8 and the arrangement of the hydraulic cylinder of the meshing device 8 can be the same as those of the mesh expanding device 6. The structure of the meshing device 8 can further expand the mesh 3 to conform to the curvature of the roof wall to be supported by the meshing device in the roadway.
[0044] As can be seen from the figure, the second transport device 7 includes two second telescopic rods 72 (e.g., Figure 6 As shown, the two second telescopic rods 72 are respectively located on the side of the fourth panel 81 and the sixth panel 83 away from the fifth panel 82. The two second telescopic rods 72 can extend from the sixth panel 83 to both sides of the net-expanding device 6 to receive the net sheet 3 located on the net-expanding device 6 and transport it from the net-expanding device 6 to the net-connecting device 8. Optionally, the two second telescopic rods 72 can be parallel to each other, facilitating installation and allowing for more stable transport of the net sheet 3.
[0045] The distance between the two second telescopic rods 72 is greater than or equal to the distance between the first panel 61 and the third panel 63 on the side away from the second panel 62 after the net is expanded by the net expanding device 6. Thus, the second transport device 7 can receive the net sheet 3 from the side of the first panel 61 and the third panel 63 away from the second panel 62, thereby ensuring that the net sheet 3 maintains its shape during transport after it is expanded.
[0046] Figure 3 This is a schematic diagram of a network expansion device according to an embodiment of the Internet access support system of the present invention.
[0047] As can be clearly seen from the figure, the mesh expansion device 6 is fixed to the device 1 by the first support 66. Specifically, the bottom end of the first support 66 is fixed to the device 1, and the top end of the first support 66 is fixed to the second panel 62.
[0048] The first panel 61 and the third panel 63 are respectively hinged to both sides of the second panel 62. The middle of both sides of the first support base 66 is provided with hinge ends, which are respectively hinged to one end of the first hydraulic cylinder 67 and one end of the second hydraulic cylinder 68. The other end of the first hydraulic cylinder 67 is hinged to the first panel 61, and the other end of the second hydraulic cylinder 68 is hinged to the third panel 63. Thus, the extension and retraction of the first hydraulic cylinder 67 and the second hydraulic cylinder 68 can respectively control the first panel 61 and the third panel 63 to fold up and down with the hinge point with the second panel 62 as the center, thereby controlling the arc of the mesh 3.
[0049] Furthermore, the first support 66 can be as follows: Figure 3 The device shown is a lifting device that can lift the first panel 61, the second panel 62 and the third panel 63, thereby lifting the mesh 3 located on the first panel 61, the second panel 62 and the third panel 63, so that the mesh 3 is closer to the roof wall of the roadway to be supported by the mesh, which facilitates the subsequent mesh support operation.
[0050] In other embodiments, the second support base 84 of the Internet access device 8 may also have the same structure as the first support base 66, thereby raising the mesh 3 so that the mesh 3 is closer to the top wall of the tunnel.
[0051] Figure 4 This is a partial schematic diagram of an embodiment of the Internet access support system of the present invention, showing a first transport device.
[0052] from Figure 4 It can be seen that the first transport device 5 is installed at the rear end of the net-expanding device 6. The first transport device 5 can extend to both sides of the lifting platform 4 to carry the net sheet 3 located on the lifting platform 4.
[0053] Specifically, the first transport device 5 includes a gear 52 and a first telescopic rod 54. The first telescopic rod 54 has a rack 54, which meshes with the teeth of the gear 52. The gear 52 can rotate to move the rack 54, thereby driving the first telescopic rod 54 to extend to both sides of the lifting platform 4 to carry the net sheet 3, or to retract from both sides of the lifting platform 4 to transport the net sheet 3 to the net expanding device 6.
[0054] Figure 5 for Figure 4 A schematic diagram of the structure of the first transport device in the embodiment.
[0055] Figure 5 The left-middle image shows the gear 52 and the first telescopic rod 54 in engagement. It is clear from the image that the rack 54 of the first telescopic rod 54 meshes with the teeth 56 of the gear 52. The gear 52 also has an axle 55, around which it can rotate, thereby extending or retracting the first telescopic rod 54 via the rack 54.
[0056] Figure 5 The right-middle figure is a side sectional view of the gear 52 and the first telescopic rod 54 in the left figure. As can be seen from the figure, the first transport device 5 also includes a motor 51. The motor 51 has an output shaft 57. The main shaft 57 is connected to the wheel axle 55 of the gear 52. Thus, the motor 51 can rotate through the output shaft 57 to transmit power to the wheel axle 55 to drive the gear 52 to rotate forward or backward, thereby controlling the extension or retraction of the first telescopic rod 54.
[0057] Figure 6 This is a partial schematic diagram of an embodiment of the Internet access support system of the present invention, showing a second transport device.
[0058] from Figure 6 As can be seen from the embodiments, the second transport device 7 includes a second telescopic rod 72, which can extend from both sides of the netting device 8 to both sides of the net-expanding device 6 to receive the net sheet 3. Specifically, the structure of the second telescopic rod 72 can be the same as that of the first telescopic rod 54, which is a gear and rack meshing structure, so that the second telescopic rod 72 can extend and retract.
[0059] Furthermore, the second transport device 7 also includes a chain moving device 73, in Figure 2 In one embodiment, the chain moving device 73 is arranged around the upper and lower surfaces of the second telescopic rod 72, and the chain moving device 73 can rotate along the upper and lower surfaces of the second telescopic rod 72.
[0060] The chain moving device 73 can adjust the position of the mesh 3 after the second telescopic rod 72 retracts, so that the position of the mesh 3 is aligned with the top wall of the roadway to be meshed. When the front-to-back width of the mesh 3 is less than the front-to-back length of the meshing device 8, the rear section of the second telescopic rod 72 carries the mesh 3 to the rear section of the meshing device 8. Through the rolling of the chain moving device 73, the mesh 3 moves forward with the chain moving device 73 to the front end of the meshing device 8, so as to align with the position of the top wall of the roadway to be meshed.
[0061] Furthermore, the chain moving device 73 is provided with a bracket 31, which is distributed among the chain links of the chain moving device 73, and the bracket 31 has a recess 32 (such as...). Figure 7 As shown, when the recess 32 is located above the second telescopic rod 72, its opening faces upward.
[0062] It is understood that the mesh panel 3 is composed of interlaced mesh lines. The recess 32 of the bracket 31 can hook the interlaced mesh lines of the mesh panel 3 to fix the position of the mesh panel 3 in the front-back direction during transportation, thereby allowing for more stable transportation of the mesh panel 3. After being transported to the meshing device 8, the mesh panel 3 is lifted relative to the bracket 31 and can be removed from the recess 32, thus detaching from the bracket 31.
[0063] It should be noted that the first transport device 5 may also be equipped with a bracket 31 to smoothly transport the net sheet 3 from the lifting platform 4 to the net expanding device 6.
[0064] Figure 7 This is a schematic diagram of the second transport device in one embodiment of the Internet access support system of the present invention.
[0065] Figure 7 In another embodiment of the second transport device 7, as can be seen from the left figure, the second transport device 7 is a hydraulic cylinder. The hydraulic cylinder includes a cylinder body 71 and a second telescopic rod 72 connected to the cylinder body. The second telescopic rod 72 can extend from the cylinder body 71 to both sides of the net-expanding device 6 to carry the net sheet 3 located in the net-expanding device 6. The second telescopic rod 72 can retract into the cylinder body 71, thereby transporting the net sheet 3 to the net-connecting device 8.
[0066] Furthermore, the upper part of the second telescopic rod 72 is provided with a bracket 31, which is used to hook the interlaced wires of the mesh 3. The right figure is a front view of the left figure. It can be clearly seen from the right figure that the bracket 31 is located above the second telescopic rod 72. The bracket 31 has a Y-shaped structure, and the upper recess 32 of the Y-shaped structure is used to hook the interlaced wires of the mesh 3.
[0067] Alternatively, the bracket 31 may also be, for example, but not limited to, a U-shaped structure, as long as it has a recess 32 that can hook the network cable.
[0068] The present invention further provides a tunneling machine that includes the aforementioned network support auxiliary system. The tunneling machine configured in this way has all the features of the network support auxiliary system and therefore also has its corresponding advantages.
