Technical Field

[0001] This invention relates to the field of mining tunneling equipment technology, specifically to an anchor mesh auxiliary installation device, an anchor mesh laying method, and an integrated tunneling and anchoring machine. Background Technology

[0002] The tunnel boring and anchor bolting (TBM) machine is a device that integrates tunnel excavation and anchor bolt support. During tunnel excavation, the installation of protective and auxiliary anchor nets is equally important. Currently, the anchor net auxiliary installation equipment equipped on TBMs is mostly installed on the upper part of the cutting arm, with a fixed coverage area. Its posture is adjusted in real time as the cutting arm moves, which not only increases the difficulty of controlling the equipment but also affects the stability of the overall structure. Furthermore, existing anchor net auxiliary installation equipment typically only serves as anchor net support and cannot provide roof support protection. Summary of the Invention

[0003] In view of this, the present invention provides an anchor net auxiliary installation device for a tunneling and anchoring machine, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.

[0004] To achieve the aforementioned objectives, the first technical solution adopted by the present invention is as follows: An auxiliary installation device for anchor mesh in a tunneling and anchoring machine, the auxiliary installation device comprising: Top support frame; A telescopic assembly that extends and retracts in a vertical direction and is used to support the top guard frame, wherein the top guard frame is rotatably connected to the upper end of the telescopic assembly via a horizontally extending pivot. An adjustment assembly is connected between the telescopic assembly and the top guard frame, and the adjustment assembly is used to adjust the rotation angle of the top guard frame on the telescopic assembly; An anchor frame is slidably disposed at the front of the top protective frame in the front-back direction.

[0005] In the aforementioned anchor net auxiliary installation equipment, optionally, the telescopic component includes a vertically arranged support column and a lifting column movably arranged on the support column in the up-down direction, and the top protective frame is rotatably connected to the upper end of the lifting column; The anchor net auxiliary installation equipment also includes a first drive mechanism, which is used to drive the top support frame to move up and down.

[0006] Optionally, the first driving mechanism is a fluid cylinder, and the two ends of the first driving mechanism are rotatably connected to the lifting column and the support column, respectively.

[0007] Optionally, the adjusting component is a fluid cylinder, and its two ends are rotatably connected to the lifting column and the top guard frame, respectively.

[0008] Optionally, the anchor net auxiliary installation device described above may further include a second drive mechanism, which is used to drive the anchor net frame to move in the front-back direction.

[0009] Optionally, the second driving mechanism is a fluid cylinder, and the two ends of the second driving mechanism are rotatably connected to the top guard frame and the anchor mesh frame, respectively.

[0010] The second drive mechanism is respectively installed on the left and right sides of the anchor mesh frame.

[0011] The front end of the anchor frame is provided with multiple fixed posts spaced apart in the left-right direction. The fixed posts are used to hold the anchor net.

[0012] Optionally, in the aforementioned anchor net auxiliary installation equipment, the adjusting component is rotatably connected to the rear of the top support frame.

[0013] In the aforementioned anchor net auxiliary installation equipment, optionally, the telescopic component and the adjustment component are respectively provided on the left and right sides of the top support frame.

[0014] Optionally, the anchor net auxiliary installation equipment described above may have at least an initial working state, a net hanging working state, and an anchor net working state. When the anchor net auxiliary installation equipment is in its initial working state, the anchor net frame and the top support frame are close together, and the top support frame extends in the horizontal direction; When the anchor net auxiliary installation equipment switches from the initial working state to the net hanging working state, the adjustment component tilts the rear of the top support frame downward, lays the anchor net on the top support frame, and hangs the front of the anchor net on the anchor net frame. When the anchor net auxiliary installation equipment switches from the net hanging working state to the anchor net working state, the adjustment component adjusts the rotation angle of the top support frame, the anchor net frame extends forward, and drives the anchor net to move onto the anchor net frame.

[0015] Further optionally, the fluid cylinder may be a hydraulic cylinder or a pneumatic cylinder.

[0016] To achieve the aforementioned objective, the second technical solution adopted by the present invention is: an integrated excavation and anchoring machine, comprising the aforementioned anchor net auxiliary installation equipment.

[0017] To achieve the aforementioned objectives, the third technical solution adopted by the present invention is: a method for laying anchor nets, employing the aforementioned anchor net auxiliary installation equipment, the anchor net laying method comprising the following steps: S1. The telescopic component is retracted downwards, and the top protective frame and the anchor mesh frame move closer together; S2. The adjusting component tilts the rear of the top guard frame downwards, then the anchor mesh is laid on the top guard frame, and the front of the anchor mesh is hung on the anchor mesh frame. S3. The adjusting component adjusts the rotation angle of the top guard frame, and then causes the anchor mesh frame to extend forward, driving the anchor mesh to move from the top guard frame to the anchor mesh frame; S4. Extend the telescopic component upwards, causing the anchor mesh frame and top support frame to move upwards, so that the anchor mesh is attached to the tunnel wall. Then, use an anchor bolting machine to pass through the anchor mesh frame and fix the anchor mesh to the tunnel wall.

[0018] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: In actual construction, the anchor net auxiliary installation equipment of this invention can not only realize anchor net support, but also realize auxiliary support and protection. The protection range is large, and the top support frame and anchor net frame can also realize multi-degree-of-freedom adjustment, making the net hanging operation faster and more convenient.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the terms "top," "bottom," "left," "right," "upper," "lower," "front," "rear," and their derivatives should be considered in relation to... Figure 2 According to this application from Zhongxiang, when the anchor mesh auxiliary installation equipment is installed on the tunneling and anchoring machine, Figure 2 The "front" in the text corresponds to the direction of the cutting arm of the tunneling and anchoring machine. Figure 2 The word "after" in this context corresponds to the tail direction of the tunneling and anchoring machine. Unless explicitly stated as the opposite, this application may use various alternative terms.

[0024] See Figures 1 to 9 As shown, the anchor net auxiliary installation equipment includes a top support frame 1, which is used for top protection and net hanging. The top support frame 1 adopts a hollow structure design.

[0025] The anchor net auxiliary installation equipment also includes telescopic components 2 set on the left and right sides of the top support frame 1. The telescopic components 2 extend and retract in the vertical direction and are used to support the top support frame 1. The top support frame 1 and each side telescopic component 2 are rotatably connected by a rotating shaft extending in the horizontal direction, which also extends in the left and right direction.

[0026] See Figure 7 and Figure 9The telescopic component 2 includes a vertically arranged support column 2a and a lifting column 2b that is movably arranged on the support column 2a in the up-down direction. The top guard frame 1 and the lifting column 2b are rotatably connected by a rotating shaft.

[0027] Specifically, see Figure 3 The support column 2a includes a hollow support column body 2a1 and copper sleeves 2a2 embedded inside the support column body 2a1 and located in the middle and upper parts of the support column body 2a1 respectively. The inner side of each copper sleeve 2a2 is provided with a groove for storing lubricating oil along its circumferential direction. An oil injection hole communicating with the groove is provided on the side wall of the copper sleeve 2a2. Lubricating oil is injected into the groove through the oil injection hole to play a lubricating role in the lifting process of the lifting column 2b.

[0028] Optionally, see Figure 4 The lifting column 2b includes a guide column 2b1 and a connecting column 2b2 disposed at the upper end of the guide column 2b1. The guide column 2b1 is inserted into the support column 2a1, and the outer side of the guide column 2b1 slides in contact with the inner side of the copper sleeve 2a2. During the contact process, the lubricating oil plays a lubricating role.

[0029] The anchor net auxiliary installation equipment also includes a first drive mechanism 4, which is used to drive the top support frame 1 to move up and down. Optionally, see [reference needed]. Figure 2 and Figure 9 The first drive mechanism 4 is a fluid cylinder, specifically a hydraulic cylinder (oil cylinder) or a pneumatic cylinder. The two ends of the first drive mechanism 4 are rotatably connected to the lifting column 2b and the support column 2a, respectively. For example, the upper end of the first drive mechanism 4 is connected to the connecting column 2b2 of the lifting column 2b.

[0030] Depend on Figure 2 and Figure 7 As can be seen, the anchor net auxiliary installation equipment also includes an adjustment component 3 connected between the telescopic components 2 on each side and the top guard frame 1. The adjustment component 3 is used to adjust the rotation angle of the top guard frame 1 on the telescopic components 2. The adjustment component 3 is a fluid cylinder, such as a hydraulic cylinder (oil cylinder) or a pneumatic cylinder. The two ends of the adjustment component 3 are rotatably connected to the lifting column 2b and the top guard frame 1, respectively. Optionally, the lower end of the adjustment component 3 is connected to the connecting column 2b2 of the lifting column 2b.

[0031] In optional embodiments, such as Figure 8 On the connecting column 2b2, the connection points between the top guard frame 1 and the connecting column 2b2, the connection points between the first drive mechanism 4 and the connecting column 2b2, and the connection points between the adjusting component 3 and the connecting column 2b2 are distributed sequentially from top to bottom.

[0032] On the top guard frame 1, the connection points between the connecting column 2b2 and the top guard frame 1, and the connection points between the adjusting component 3 and the top guard frame 1 are distributed sequentially along the front and rear direction of the top guard frame 1, so as to facilitate the adjusting component 3 to adjust the rotation angle of the top guard frame 1.

[0033] The anchor net auxiliary installation equipment also includes an anchor net frame 5 that is slidably connected to the top support frame 1 in the front-back direction, and a second drive mechanism 6 for driving the anchor net frame 5 to slide on the top support frame 1. The anchor net frame 5 is slidably connected to the front of the top support frame 1, and the adjustment component 3 is rotatably connected to the rear of the top support frame 1.

[0034] In an optional embodiment, see Figure 5 and Figure 6 Multiple sliding grooves 1a are arranged sequentially at intervals along the left and right directions on the top protective frame 1. Each sliding groove 1a extends along the front and rear directions of the top protective frame 1. Guide tubes 5b are arranged on the anchor mesh frame 5 at the positions corresponding to the sliding grooves 1a. Each guide tube 5b is slidably inserted into the corresponding sliding groove 1a.

[0035] The second drive mechanism 6 is a fluid cylinder, specifically a hydraulic cylinder (oil cylinder) or a pneumatic cylinder. The two ends of the second drive mechanism 6 are rotatably connected to the anchor frame 5 and the top protection frame 1, respectively. The second drive mechanism 6 is set on the left and right sides of the top protection frame 1, so that the sliding of the anchor frame 5 is more stable.

[0036] like Figure 6 As shown, multiple fixed posts 5a are sequentially and spaced apart along the left and right direction at the front end of the anchor mesh frame 5. The fixed posts 5a are used to hold the anchor mesh.

[0037] The anchor net auxiliary installation equipment has at least an initial working state, a net hanging working state, and an anchor net working state; See Figure 2 When the anchor net auxiliary installation equipment is in the initial working state, the anchor net frame 5 is close to the top protection frame 1, the support column 2a and the lifting column 2b are close together, and the adjustment component 3 extends to make the top protection frame 1 extend in the horizontal direction. See Figure 7 When the anchor net auxiliary installation equipment switches from the initial working state to the net hanging working state, the adjusting component 3 retracts to tilt the rear of the top support frame 1 downward, lays the anchor net on the top support frame 1, and hangs the front of the anchor net on the fixed column 5a of the anchor net frame 5. See Figure 8When the anchor net auxiliary installation equipment switches from the net hanging working state to the anchor net working state, the adjusting component 3 extends to adjust the rotation angle of the top support frame 1 (such as adjusting the top support frame 1 to extend in the horizontal direction). The second drive mechanism 6 drives the anchor net frame 5 to extend forward, moving the anchor net from the top support frame 1 to the anchor net frame 5. The first drive mechanism 4 drives the lifting column 2b to move upward, moving the anchor net frame 5 and the top support frame 1 upward simultaneously, so that the anchor net is attached to the tunnel wall. The anchor bolt machine passes through the anchor net frame 5 to fix the anchor net to the tunnel wall. At the same time, the top support frame 1 can be used for roof support and protection, further improving the operation safety of the operators.

[0038] Another embodiment of the present invention provides a tunneling and anchoring integrated machine, including a main unit, a cutting arm movably disposed at the front of the main unit, and an anchor net auxiliary installation device. The anchor net auxiliary installation device is disposed on the main unit and does not move with the cutting arm, and is used to provide timely support for the tunnel wall cut by the cutting arm.

[0039] The following describes the method for laying anchor nets using this anchor net auxiliary installation equipment, including the following steps: I. Initial Stage At this stage, such as Figure 2 The second drive mechanism 6 retracts, the anchor frame 5 moves closer to the top support frame 1, and the telescopic component 2 retracts downward. Specifically, the lifting column 2b slides downward until it moves closer to the support column 2a, and the adjusting component 3 extends to make the top support frame 1 extend horizontally.

[0040] II. Online Posting Phase The anchor net installation auxiliary equipment is switched from the initial stage to the net hanging stage, such as... Figure 7 The adjusting component 3 retracts to tilt the rear of the top support frame 1 downwards, the anchor net is laid on the top support frame 1, and the front of the anchor net is hung on the fixed column 5a of the anchor net frame 5.

[0041] III. Anchor Net Stage The anchor net auxiliary installation equipment switches from the net-hanging working state to the anchor net working state, such as... Figure 8 The adjusting component 3 extends to adjust the rotation angle of the top support frame 1 (such as adjusting the top support frame 1 to extend horizontally). The second drive mechanism 6 drives the anchor mesh frame 5 to extend forward, moving the anchor mesh from the top support frame 1 to the anchor mesh frame 5 and laying it flat on the anchor mesh frame 5. The first drive mechanism 4 drives the lifting column 2b to move upward, moving the anchor mesh frame 5 and the top support frame 1 upward simultaneously, so that the anchor mesh is attached to the tunnel wall. The anchor bolt machine passes through the anchor mesh frame 5 to fix the anchor mesh to the tunnel wall.

[0042] During this stage, the top support frame 1 can also be used to assist in the protection of the tunnel roof, making it safer for personnel to operate below.

[0043] Fourth, restore the anchor net auxiliary installation equipment to the initial stage, that is, retract the first drive mechanism, retract the second drive mechanism, bring the top support frame and anchor net frame together, and bring the lifting column and support column together. Then repeat steps two and three to lay the next anchor net.

[0044] During the tunneling process, the cutting arm of the integrated tunneling and anchoring machine advances forward. The operator uses the anchor mesh auxiliary installation equipment to lay an anchor mesh. After the cutting arm completes one stroke, the integrated tunneling and anchoring machine moves forward one stroke, then moves to the next stroke and lays another anchor mesh. This cycle continues until the anchor mesh is laid on the entire tunnel wall. Furthermore, during the anchor mesh laying process, the top support frame can also be used to assist in supporting the tunnel roof protection. The top support frame supports the anchor mesh sheet laid in the previous stroke, making the operation safer for the operator.

[0045] This anchor net auxiliary installation equipment can also be used for roof support protection, such as... Figure 9 As shown, during the top protection, the second drive mechanism retracts, the anchor mesh frame and the top protection frame move closer together, the adjustment component makes the top protection frame extend horizontally, the first drive mechanism extends, and the top protection frame and the anchor mesh frame move upward. The top protection frame is used for top protection.

For example, they can refer to direct connection or indirect connection through an intermediate medium.
