Description

Technical Field

[0001] This invention relates to the field of coal mine construction equipment technology, specifically to an integrated tunneling, anchoring, and exploration machine. Background Technology

[0002] In high-gas coal mines, gas verification and emission must be conducted before tunneling can proceed. Currently, gas verification and emission require manual drilling with handheld rigs to drill holes, collect dust, weigh it, and then take a small sample to measure the S and K values ​​of the gas. This process is slow, inefficient, and almost entirely manual, lacking adequate personnel protection.

[0003] Traditional roadway tunneling and anchoring machines often use rigid supports for temporary tunneling. While these can protect operators to some extent during artificial gas verification, the protection is limited and fails to adequately protect the tunnel itself. Furthermore, traditional roadway tunneling and anchoring machines struggle to achieve simultaneous tunneling and anchoring operations. Summary of the Invention

Detailed Implementation

[0021] Referring to the accompanying drawings and specific embodiments, the structure, composition, features, and advantages of the integrated tunneling, anchoring, and exploration machine of the present invention will be described below by way of example; however, all descriptions should not be construed as limiting the present invention in any way.

[0022] For any single technical feature described or implied in the embodiments submitted herein, or any single technical feature shown or implied in the various drawings, the present invention still operates in any combination or deletion among these technical features or their equivalents without any technical obstacle, and thus these further embodiments according to the present invention should also be considered within the scope of the description herein.

[0023] Furthermore, the terms "first," "second," "third," "fourth," "fifth," and "sixth" 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. Therefore, a feature defined with "first," "second," "third," "fourth," "fifth," or "sixth" may explicitly or implicitly include at least one of those features. Additionally, the terms "top," "bottom," "left," "right," "upper," "lower," "front," "rear," and their derivatives should be considered in relation to... Figure 1 In this application, the cutting drum direction is forward and the tail direction is backward. However, it should be understood that, except where explicitly stated that they are opposite, this application may use various alternative terms.

[0024] See Figures 1 to 3 The tunneling, anchoring, and exploration integrated machine shown includes a walking device, a cutting device 200, a gas verification device 300, a support device 400, an anchor net auxiliary device 500, an anchor protection device, a loading device 700, a transportation device 800, and a dust removal device.

[0025] The traveling device serves as the supporting device for the entire tunneling and anchoring integrated machine. It includes a main frame 11 and a traveling unit 16 located at the bottom of the main frame 11. The traveling unit 16 can be a tracked traveling unit.

[0026] The cutting device 200 is movably mounted on the main frame 1 along the front-to-back direction of the tunneling and anchoring integrated machine, and the front part of the cutting device can also be movably mounted in the vertical direction. See [reference needed]. Figure 4 As can be seen, the cutting device 200 includes a cutting boom 21 and a cutting drum 22 connected to the front end of the cutting boom 21. The cutting drum 22 can rotate on the cutting boom 21 to cut the mine shaft along the tunneling direction to form a roadway. Optionally, the cutting drum 22 is driven to rotate by a reducer and a motor mounted on the cutting boom 21.

[0027] Optionally, the cutting device 200 is connected to the main frame 1 via the sliding frame 12. The sliding frame 12 is slidably connected to the main frame 1 in the front-back direction. A fifth drive mechanism (not shown in the figure) for driving the sliding frame 12 to slide is also provided between the sliding frame 12 and the main frame 1. For example, the fifth drive mechanism can be a hydraulic cylinder.

[0028] See Figure 5 and Figure 6The sliding frame 12 includes a sliding frame body 121 slidably connected to the main frame 1 in the front-rear direction and a sliding frame connecting part 122 formed on the sliding frame body 121. The main frame 1 has guide rails extending in the front-rear direction on its left and right sides respectively. The sliding frame body 121 has sleeves that can be fitted onto the guide rails on both sides, and a fifth drive mechanism drives the sleeves of the sliding frame body 121 to slide along the length direction of the guide rails. The rear end of the cutting arm 21 of the cutting device is hinged to the sliding frame connecting part 122 via a first pin 123 extending in the left-right direction. A telescopic mechanism 14 is hinged between the middle of the cutting arm 21 of the cutting device and the sliding frame connecting part 122 (see...). Figure 4 The lower end of the telescopic mechanism 14 is hinged to the sliding frame connection 122 via a second pin 124 extending in the left-right direction, and the upper end of the telescopic mechanism 14 is hinged to the middle of the cutting arm 21. For example, the telescopic mechanism 14 can be a hydraulic cylinder. In this way, on the one hand, the cutting device slides back and forth on the main frame 1 under the action of the fifth drive mechanism driving the sliding frame 12 to slide in the back-and-forth direction, so that the cutting device can advance forward by one stroke (e.g., the stroke is set to 1m) when the traveling device is stationary. On the other hand, the cutting drum 22 swings up and down under the telescopic drive of the telescopic mechanism 14.

[0029] During the cutting operation, the cutting drum 22 rotates at a constant speed driven by the motor and reducer. The telescopic mechanism 14 drives the cutting drum 22 to move up and down, thereby cutting the front coal wall. At the same time, driven by the sliding frame, the cutting drum can move forward to cut the coal wall without moving the traveling device, completing one cutting distance. When cutting for the next cycle, the sliding frame drives the cutting drum to retract, and the entire tunneling and anchoring integrated machine moves forward one stroke, and then the above cutting action is repeated.

[0030] See also Figure 2 and Figure 3 The loading device 700 is located at the front of the main frame 11. The loading device 700 can collect the slag cut off by the cutting drum 22. The transport device 800 extends in the front-back direction and is located on the main frame 1. The transport device 800 is connected to the loading device 700. The transport device 800 can transport the slag collected by the loading device 700 out. At the same time, the transport device 800 is also located on the sliding frame 12 and is slidably connected to the sliding frame.

[0031] See also Figure 1 and Figure 3The gas verification device 300 includes a first gas detection drill 31 mounted on the main frame 11 and located on both sides of the cutting arm 21 of the cutting device, and a second gas detection drill 32 mounted on the cutting arm 21 of the cutting device. The first gas detection drill 31 can be slidably mounted on the main frame 11 in the front-back direction, and the second gas detection drill 32 can be slidably mounted on the cutting arm 22 in the front-back direction. Both the first gas detection drill 31 and the second gas detection drill 32 are driven by hydraulic cylinders. After the tunneling and anchoring operation is completed, when gas detection is required, the device switches to the gas detection mode. The first gas detection drill 31 and the second gas detection drill 32 slide forward under the action of their respective hydraulic cylinders. At the same time, the up, down, left and right angles of the drill rigs can be adjusted. When the drill rig hits the coal face and stops advancing, the drill rig starts drilling and dust extraction, and detects relevant gas data. Gas verification personnel can work under the protection of the support device, which greatly ensures the safety of the personnel.

[0032] See Figure 7 Combination Figure 1 The support device 400 is a flexible shield support device. The support device is installed on the main frame 11 and located behind the cutting drum 22. The support device is also covered above the cutting boom 21, the first gas detection drill 31 and the second gas detection drill 32.

[0033] As shown in the figure, the support device 400 includes a main frame 41 mounted on the main frame 11 and located behind the cutting drum 22, a flexible top shield 42 movably mounted on the top of the main frame 41 in the vertical direction, flexible side shields 43 movably mounted on the left and right sides of the main frame 41 in the horizontal direction, a first drive mechanism for driving the flexible top shield 42, and second drive mechanisms for driving the flexible side shields 43 on both sides. After the flexible top shield 42 extends, it can be used to support the roof of the roadway, and after the flexible side shields 43 extend, they can be used to support the sidewalls of the roadway. On the one hand, it can continuously protect the roof and sidewalls, maintain a support force that is balanced with the pressure of the roadway roof, and the support force can change with the change of roof pressure, protect the roadway from deformation, prevent the roadway from leaving the roof during step changes, continuously provide support force to the roof, and at the same time maintain a small unsupported roof distance during excavation, protecting the safety of operators.

[0034] In an optional embodiment, the flexible top shield 42 includes a top support 421 movably mounted on the main frame 41 in the vertical direction and flexible track mechanisms 44 arranged sequentially on the top support 421 in the horizontal direction. The top support 421 and the main frame 41 are slidably connected by guide rails and guide grooves in the vertical direction. The first drive mechanism is a hydraulic cylinder arranged in the vertical direction, and the upper and lower ends of the first drive mechanism are hinged to the main frame 41 and the top support 421, respectively. The flexible side shield 43 includes side supports 431 movably mounted on the left and right sides of the main frame 41 in the horizontal direction and flexible track mechanisms 44 arranged sequentially on the side supports 431 in the vertical direction. The tracks of each flexible track mechanism 44 extend in the front-back direction and can move under the frictional force of contact with external components. The tracks of the flexible track mechanisms 44 can contact the roof and sidewalls of the tunnel, which can buffer pressure, absorb local deformation of the rock, protect the roof and sidewalls, and avoid damage to the surrounding rock. When the whole machine moves forward, the tracks roll and rub against the tunnel, reducing the propulsion resistance.

[0035] See Figure 8 Each flexible track mechanism 44 includes a track frame, which includes support rods 441 arranged on opposite sides and a stop bar 447 connected between the support rods 441 on both sides. The support rods 441 and the stop bar 447 together form an accommodating space. The support rods 441 on both sides are arranged in a basically parallel manner. The stop bar 447 and the support rods 441 on both sides can be connected by welding, bolts or other means.

[0036] The flexible track mechanism 44 also includes a track 442, a roller unit, and a limiting rod 448. The track 442 extends along the length of the support rod 441 and is located within the accommodating space. The roller unit includes a first roller assembly 444, a plurality of second roller assemblies 445, and a third roller assembly 446, which are arranged sequentially along the length of the track 442 and pass through the track 442. The two ends of the first roller assembly 444, the two ends of each of the second roller assemblies 445, and the two ends of the third roller assembly 446 are respectively connected to the two side support rods 441. The limiting rod 448 is provided on the two side support rods 441. The limiting rod 448 and the stop rod 447 are located on both sides of the track 442. The limiting rod 448 is used to restrict the roller unit to the support rod 441. Both ends of the first idler assembly 444, both ends of each of the second idler assemblies 445, and both ends of the third idler assembly 446 can be slidably connected to the support rod 441 along the length direction of the support rod 441.

[0037] As shown in the figure, the first idler assembly 444 is located near the stop bar 447, and the third idler assembly 446 is located near the limit bar 448. The first idler assembly 444 abuts against the adjacent second idler assembly 445, and multiple second idler assemblies 445 abut against each other. An adjustment space 449 for adjusting the track tension is reserved between the third idler assembly 446 and the adjacent second idler assembly 445. The third idler assembly 446 also abuts against the limit bar 448.

[0038] The flexible track mechanism also includes an adjustment assembly for adjusting the tension of the track 442. The adjustment assembly includes an adjustment member, which is an adjustment bolt 443, that is movably mounted on the support rods 441 on both sides. The adjustment bolt 443 passes through the limiting rod 448 and the third idler assembly 446 in sequence. The end of the adjustment bolt 443 abuts against the second idler assembly 445 adjacent to the third idler assembly 446. The adjustment bolt 443 is also threadedly connected to the third idler assembly 446. By rotating the adjustment bolt 443, the limiting rod 448 restricts the movement of the third idler assembly 446. During the rotation of the adjustment bolt 443, the length of the part of the adjustment bolt 443 exposed on the third idler assembly 446 will change, thereby changing the length of the adjustment space 449 and thus changing the tension of the track 442.

[0039] In an optional embodiment, guide grooves are provided on the support rods 441 on both sides at the positions corresponding to the idler roller units. Each guide groove extends along the length direction of the corresponding support rod 441. The two ends of the first idler roller assembly 444, the two ends of each second idler roller assembly 445, and the two ends of the third idler roller assembly 446 are respectively located in the guide grooves on both sides and can slide along the length direction of the guide grooves.

[0040] The first idler assembly 444, each of the second idler assemblies 445 and the third idler assembly 446 each have an idler that can rotate around its own axis. The rotation of each idler does not interfere with each other. The track 442 is wound around all the idlers. When the track 442 contacts the roof and sidewalls of the roadway, it drives the idlers to rotate under the action of friction, thereby realizing movement.

[0041] See also Figure 9 and Figure 10 The first idler assembly, each of the second idler assemblies 445 and the third idler assembly 446 each include a central shaft 4410, sliders 4411 disposed at both ends of the central shaft 4410, idler rollers 4412 sleeved on the central shaft 4410 and capable of rotating around the axis of the central shaft 4410, and end caps sleeved on the central shaft 4410 and respectively connected to the two ends of the idler rollers 4412. Each slider 4411 is located in a guide groove. The track 442 is wound around all the idler rollers 4412. Bearings are provided between the idler rollers 4412 and the central shaft 4410.

[0042] like Figure 10 As shown, the slider 4411 of the first idler assembly abuts against the slider of the adjacent second idler assembly, and the sliders of two adjacent second idler assemblies abut against each other. A gap is formed between the idler 4412 of the first idler assembly and the idler 4412 of the adjacent second idler assembly, and a gap is formed between the idlers of two adjacent second idler assemblies, so that each idler 4412 does not interfere with each other during rotation. An adjustment space 449 is formed between the slider 4411 of the third idler assembly and the slider 4411 of the adjacent second idler assembly. An adjusting bolt 443 is threadedly connected to the slider 4411 of the third idler assembly, and the end of the adjusting bolt 443 abuts against the slider 4411 of the second idler assembly 445.

[0043] Track 442 uses rubber tracks, which are a type of ring track, with steel wire rope as the internal reinforcement layer.

[0044] During tunneling and anchoring operations, the flexible top shield and flexible side shield extend and press against the roadway roof and sidewalls under the action of the driving cylinders. The tracks contact the roof and sidewall coal walls, supporting and protecting the roadway. The supporting force of the flexible top shield and flexible side shield can be actively adjusted according to the load on the roof or sidewalls to ensure that the supporting force is balanced with the roadway pressure. When the tunneling, anchoring and exploration machine moves forward, the flexible top shield and flexible side shield continue to support the roadway roof and sidewalls, and the tracks roll on the coal wall. In the gas verification mode, the flexible top shield and flexible side shield continue to support the roadway roof and sidewalls to protect the roadway, while also protecting the gas verification personnel inside the support device.

[0045] See also Figure 1 and Figure 3 The anchoring device includes a top anchor bolting machine 61 and side anchor bolting machines 62 installed on the left and right sides of the main frame 11. The top anchor bolting machine 61 is located behind the support device 400. The top anchor bolting machine 61 is used to drive anchor bolts into the roadway roof to fix the anchor net to the roadway roof. The side anchor bolting machines 62 are used to anchor the upper anchor bolts on both sides of the roadway. The side anchor bolting machines 62 are located behind the anchor net auxiliary device 500.

[0046] See Figure 2 and Figure 3 The anchor net auxiliary device 500 is installed on the main frame 11 and located behind the support device 500. The anchor net auxiliary device is used for anchor net laying and top support protection.

[0047] See also Figures 11 to 14The anchor mesh auxiliary device 500 includes a support column 51, a lifting column 52 movably mounted on the support column 51 in the vertical direction, a top protection frame 53 mounted on the top of the lifting column 52, and an anchor mesh frame 54 slidably mounted in front of the top protection frame 53 in the front-back direction. The top protection frame 53 is used for top support and protection, and the anchor mesh frame 54 is used for laying the anchor mesh. Multiple fixed columns 541 are sequentially spaced at intervals along the left-right direction at the front end of the anchor mesh frame 54. The fixed columns 541 are used for hanging the mesh.

[0048] The anchor net auxiliary device 500 also includes a third drive mechanism 55 for driving the lifting column 52 to move in the up and down direction and a fourth drive mechanism 56 for driving the anchor net frame 54 to move back and forth. The third drive mechanism 55 and the fourth drive mechanism 56 can be hydraulic cylinders or pneumatic cylinders.

[0049] Depend on Figure 13 and Figure 14 As can be seen, support columns 51 are provided on both the left and right sides of the top support frame 53. The support columns 51 on both sides are respectively arranged on the left and right sides of the main frame 11. A lifting column 52 is provided on each support column 51. A third drive mechanism 55 is provided between each support column 51 and the lifting column 52. A fourth drive mechanism 56 is provided on the left and right sides of the anchor mesh frame 54.

[0050] The top support frame 53 is rotatably connected to the tops of the two side lifting columns 52 via rotating shafts extending in the left-right direction. The anchor net auxiliary device also includes an adjustment assembly 57 connected between the lifting columns 52 and the top support frame 53. This adjustment assembly 57 is used to adjust the rotation angle of the top support frame 53 on the lifting columns 52. The adjustment assembly 57 can be a hydraulic cylinder. An adjustment assembly 57 is provided between each side of the lifting column 52 and the top support frame 53.

[0051] When the anchor mesh frame 54 extends forward, the front end of the anchor mesh frame 54 is close to the support device. The top anchor bolt machine 61 is located below the anchor mesh frame 54. If four top anchor bolt machines are set, each top anchor bolt machine can slide left and right and swing back and forth. The side anchor bolt machine 62 is located behind the anchor mesh auxiliary device 500. The side anchor bolt machine can move up and down and swing up and down, increasing the anchor protection range and reducing the anchor bolt tilt angle, thereby improving the anchor protection effect.

[0052] This anchor-mesh auxiliary device allows for simultaneous tunneling and anchor-mesh support. The specific working process is as follows: During the tunneling process, the cutting device retracts the lifting column 52 to be close to the support column 51, and retracts the anchor mesh frame 54 to be close to the top support frame 53. The adjustment component 57 is used to tilt the rear of the top support frame 53 downward, lay the anchor mesh on the top support frame 53, and hang the front of the anchor mesh on the fixed column 541 of the anchor mesh frame 54.

[0053] The adjusting component 57 extends to adjust the top support frame 53 to a horizontal position. Then, the anchor mesh frame 54 extends forward and approaches the support device, moving the anchor mesh from the top support frame to the anchor mesh frame 54 and laying it flat. Next, the lifting column 52 is driven to rise, causing the top support frame and the anchor mesh frame to rise together, so that the anchor mesh adheres to the tunnel roof. Finally, the top anchor bolting machine 61 below the anchor mesh frame fixes the anchor mesh to the tunnel roof. Simultaneously, the top support frame can be used to assist in supporting the tunnel roof protection, making personnel operation safer.

[0054] After the cutting device retracts after one stroke, the anchor net auxiliary device assists in the laying of the roof anchor net, the lifting column descends, and the anchor net frame retracts at the same time to prepare for the laying of the next anchor net. The laying of the next anchor net can also be carried out when the cutting device is cutting the roadway.

[0055] See Figure 1 The integrated tunneling and anchoring exploration machine also includes a dust removal device, which includes a water mist dust removal mechanism 91 and a foam dust removal mechanism 92 mounted on the main frame 11. The water mist dust removal mechanism 91 includes a water spray module and a wet dust collector, and the foam dust removal mechanism 92 includes a foam generator and a foam spray module. During operation, the two dust removal methods are used simultaneously. Foam is used to cover the coal dust that has not yet been raised to suppress dust generation, while water mist is used to wash the coal dust that has already been raised. At the same time, the wet dust collector is used for air filtration and dust removal. The combination of the two dust removal methods enhances the effect and purifies the environment.

[0056] The integrated tunneling and anchoring machine also includes side guards 15 that are movably arranged on the left and right sides of the main frame 11 in the left-right direction, and a sixth drive mechanism for driving the movement of the side guards 15 on both sides, such as... Figure 1 As shown, the side guard plate 15 is located on both sides of the anchor net auxiliary device.

[0057] The integrated tunneling and anchoring exploration machine also includes an electro-hydraulic control system for controlling its operation. This system comprises a hydraulic system and an electrical system. The hydraulic system consists of a hydraulic tank, hydraulic pump, pump station motor, valve group box, filter, cooler, hydraulic valve group, and hydraulic pipelines, providing power to the hydraulic motors and cylinders on the equipment. The electrical system consists of an electrical control box, valve control box, remote control, switch, display screen, lighting, camera, and gas power-off device, providing the equipment with electric drive force, gas monitoring, and video surveillance functions.

[0058] The integrated tunneling, anchoring, and gas verification machine of this invention is suitable for tunneling, anchoring, and gas verification operations in high-gas mine roadways. It has functions such as roadway tunneling, roadway anchoring, gas verification and emission, flexible shield support, loading and transportation, netting and top netting, and dust removal and suppression. It integrates multiple functions into one machine, achieving the effect of one machine with multiple functions. Furthermore, the integrated tunneling, anchoring, and gas verification machine has a tunneling and anchoring mode, a gas verification mode, and a walking mode. These three modes can be switched according to needs. When in tunneling and anchoring mode, tunneling and anchoring operations are carried out simultaneously. When in gas verification mode and walking mode, the support device can continuously provide support.

[0059] Traditional tunneling equipment often lacks temporary support or has only a small area of ​​temporary support during tunnel excavation, limiting personnel protection. Furthermore, the support force is low and difficult to adjust, unable to adapt to changes in roof pressure. The large gap between the temporary support and the roof makes the tunnel prone to deformation or collapse. Additionally, the temporary supports or shields of traditional tunneling equipment experience significant sliding friction between the support structure and the tunnel wall, resulting in high resistance. Moreover, the rigid materials used in the support structure, such as steel plates or frames, easily damage the tunnel roof. Some tunneling equipment's temporary supports cannot function during tunneling operations, only providing support when the equipment is stopped, thus offering limited protection to the tunnel.

[0060] The tunneling, anchoring, and exploration integrated machine of this invention adopts a flexible shield-type support device combined with an anchor mesh auxiliary device. Firstly, the support device can continuously provide support during both tunneling and anchoring operations, allowing tunneling and anchoring to proceed simultaneously. This solves the drawbacks of not being able to anchor during tunneling and not being able to tunnel during anchoring. Furthermore, the anchoring personnel are protected by the support device, greatly improving tunneling efficiency and safety. Secondly, the support device can continuously protect the roof and sidewalls, maintaining a support force balanced with the pressure of the roadway roof. The support force can change with the roof pressure, protecting the roadway from deformation, ensuring no separation from the roof during step changes, continuously providing support to the roof, and maintaining a small unsupported distance during tunneling. Further, the tracks of the support device contact the roadway roof / sidewalls, buffering pressure, absorbing local rock deformation, protecting the roof and sidewalls, and preventing damage to the surrounding rock. During machine advancement, the tracks and roadway experience rolling friction, reducing propulsion resistance. Thirdly, the anchor net auxiliary device has the functions of top netting and net delivery, which greatly improves the efficiency of anchor protection and solves the problem of manual netting and networking. In addition, the anchor net auxiliary device also has the function of auxiliary support and protection. The anchor protection operation can be carried out under the protection of the support device, and the safety of the operators is high.
