Description

Technical Field

[0002] Coal mining is mainly divided into surface mining and underground mining, and the vast majority of coal mines in China belong to underground mining. In underground coal mining, roadway tunneling is an important production task in coal mining and a prerequisite for the smooth exploitation of coal fields. According to the functions of roadways, they are divided into equipment transportation roadways, ventilation roadways, etc. Therefore, the rapid and efficient excavation of tunneling roadways directly affects the overall efficiency and production capacity of coal mines. In roadway construction, it is mainly divided into three construction processes: tunneling, bolt support, and transportation.

[0003] Existing combined tunneling and bolting machines include a tunneling device and a bolting device that are integrally arranged. When the tunneling device or the bolting device fails, the other device cannot be used; when the whole machine is under maintenance, neither the tunneling nor the bolting function can be operated, which will inevitably affect the production efficiency of coal mines. At the same time, the working geological conditions of existing combined tunneling and bolting machines are relatively harsh and limited in number. The operation of the equipment is more complex, and it is easily restricted by working conditions and cannot complete the one-time anchoring of all roof bolts and rib bolts. Other bolting equipment is still required for supplementary bolting operations; the combined tunneling and bolting machine also includes equipment such as a belt conveyor, a dust suppression device, and an electric control system, which occupy the roadway, increasing the operation difficulty of the supplementary bolting equipment and making it difficult to carry out supplementary bolting in a timely manner, thus bringing potential safety hazards to coal mine operations.

[0033] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 - 10 , the present invention provides a combined tunneling and bolting operation device, including a tunneling device 1, and the tunneling device 1 is connected to a bolt device 2 through a drag chain 3. The tunneling device 1 is used for coal mine roadway excavation, loading and transportation.

[0035] Refer to Figure 3, the tunneling equipment 1 includes a frame 102. Second crawler mechanisms 101 are respectively arranged at the bottom sides of the frame 102, and the tunneling equipment moves forward and backward under the drive of the second crawler mechanisms 101; a slewing platform 103 is arranged on the right side of the frame 102, and the slewing platform 103 is connected to a cutting head 109 through a cutting arm 104. The slewing platform 103 is used to drive the cutting arm 104 to rotate and swing, and the cutting arm 104 drives the cutting head 109 to swing up, down, left and right in the roadway to excavate the width and height of the roadway. A slag loading shovel plate 105 located under the slewing platform 103 is arranged on the right side of the frame 102, and a conveyor 106 connected to the slag loading shovel plate 105 is arranged on the frame 102. After the coal slag falling after the roadway is excavated is collected by the slag loading shovel plate 105, it is conveyed to the conveyor 106 and transferred to the next process; a hydraulic pump station 107 is arranged on the frame 102, which is used to provide a hydraulic power source for hydraulic components such as hydraulic pumps and hydraulic motors of the integrated mining and bolting device, so as to realize the actions of each mechanism; an electric control cabinet 108 is arranged on the frame 102, which is used to provide power supply and electrical control for the integrated mining and bolting device.

[0036] The bolt equipment 2 includes a sliding rack 204. A first sliding mechanism sliding along the X direction is arranged at the bottom of the sliding rack 204, and the first sliding mechanism and the gantry are arranged on the traveling mechanism; a second sliding mechanism sliding along the Z direction is arranged on the sliding rack 204, and the second sliding mechanism is connected to a lifting cross beam 213; a third sliding mechanism sliding along the Y direction is arranged on the lifting cross beam 213, and the third sliding mechanism is connected to a bolt machine through a double rotation mechanism 212.

[0037] In this device, through the arranged first sliding mechanism, second sliding mechanism and third sliding mechanism, the bolt machine can be moved in three-dimensional space, and the angle of the bolt machine can be adjusted through the arranged double rotation mechanism 212. Therefore, the bolt machine can carry out anchoring and supporting operations at any position in the roadway.

[0038] In the integrated mining and bolting device, after the tunneling equipment 1 excavates the roadway into shape, the tunneling equipment 1 does not need to retreat and withdraw. Due to the cavity structures of the gantry and the sliding rack 204, the bolt equipment 2 can straddle on the tunneling equipment 1, and the bolt equipment 2 can carry out support and bolt operations on the forefront of the newly excavated roadway. The power hydraulic oil of hydraulic components such as hydraulic pumps and hydraulic motors in the bolt equipment 2 is supplied by the hydraulic pump station 107 of the tunneling equipment 1. The tunneling equipment 1 and the bolt equipment 2 are connected through a drag chain 3, and all hydraulic pipelines can be laid in the driving drag chain 3; the arranged drag chain 3 only plays the role of connecting the tunneling equipment 1 and the bolt equipment 2. In summary, the tunneling equipment 1 and the bolt equipment 2 are perfectly connected, and the excavation and mining efficiency of the coal mine roadway can be effectively improved.

[0039] Reference Figures 4 - 6As shown in FIGS. 8 and 9, the traveling mechanism includes a first crawler mechanism 201 and a hydraulic motor 202 for driving the first crawler mechanism 201 to travel. The gantry includes a plurality of support legs 205 and a frame formed by two connecting cross beams 206 and a connecting longitudinal beam 207; the tops of the support legs 205 are fixed to the frame, and the bottoms of all the support legs 205 located on both sides of the connecting cross beam 206 are respectively fixed to the two first crawler mechanisms 201. The provided gantry is used to fixedly connect the two first crawler mechanisms 201 to achieve synchronous traveling.

[0040] The sliding frame 204 includes two rear columns 216 and a front column 217, and the tops of the two rear columns 216 and the front column 217 are fixedly arranged on a rectangular connecting beam 218.

[0041] Continue to refer to Figures 4 - 6 As shown in FIGS. 8 and 9, the first sliding mechanism includes slide rails 203 respectively arranged on each first crawler mechanism 201. Sliding plates 215 are arranged at the bottoms of the rear columns 216 and the front column 217 on the same side, and the sliding plates 215 are slidably arranged in the slide rails 203. A second hydraulic cylinder 219 is fixedly arranged in the slide rail 203 on the side close to the gantry, and the telescopic end of the second hydraulic cylinder 219 is fixedly connected to the sliding plate 215.

[0042] Specifically, the length direction of the slide rail 203 is the same as the horizontal tangent direction of the first crawler mechanism 201, which is the same as the above-mentioned X direction. By driving the sliding plate 215 to slide in the slide rail 203 through the second hydraulic cylinder 219, the sliding plate 215 and the sliding frame 204 move synchronously. In this way, when the bolt equipment 2 cooperates with the tunneling equipment 1 in the roadway and cannot move forward when encountering an obstacle, the sliding frame 204 can be extended to cross the obstacle to achieve the anchoring operation at the more front end.

[0043] Refer to Figures 4 - 6 As shown in FIGS. 6, 7 and 9, the second sliding mechanism includes a third hydraulic cylinder 221 and a chain 226. First sliders 229 are arranged at both ends of the lifting cross beam 213, and slide ways 225 are arranged on each front column 217. The first sliders 229 are slidably arranged in the slide ways 225; a pulley 227 is arranged on the telescopic end of the third hydraulic cylinder 221, the bottom end of the third hydraulic cylinder 221 is fixed on the sliding plate 215, one end of the chain 226 is arranged at the bottom end of the third hydraulic cylinder 221, and the other end bypasses the pulley 227 and is connected to the first slider 229.

[0044] By extending or retracting the telescopic end of the third hydraulic cylinder 221 to drive the pulley 227 to move up and down, the chain 226 can rotate on the pulley 227, so that the other end of the chain 226 drives the first slider 229 to move up and down in the slide way 225 inside the front column 217, and the first slider 229 drives the lifting cross beam 213 to move up and down, thereby realizing the side anchoring operation of the bolt machine at different heights in the coal mine roadway.

[0045] Reference Figures 4 - 6 As shown in FIGS. 8 and 9, the third sliding mechanism includes a fourth hydraulic cylinder 228 and two second sliding blocks 214 slidably disposed on the lifting cross beam 213. A fixing plate 232 is provided on the lifting cross beam 213. The bottom end of the fourth hydraulic cylinder 228 is hinged to the fixing plate 232, and the two telescopic ends of the fourth hydraulic cylinder 228 are respectively hinged to the two second sliding blocks 214. Specifically, the bottom end of the fourth hydraulic cylinder 228 is mounted on the fixing plate 232 through a first hinge seat 231, and the telescopic end is mounted on the second sliding block 214 through a second hinge seat 235.

[0046] The extension or shortening of the telescopic end of the fourth hydraulic cylinder 228 drives the second sliding block 214 to horizontally slide left and right on the lifting cross beam 213. The second sliding block 214 moving left and right drives the bolter to horizontally move left and right, thereby realizing the roof bolting operation of the bolter at different positions on the top of the coal mine roadway.

[0047] Continue to refer to Figures 4 - 6 As shown in FIGS. 8 and 9, a double-rotation mechanism 212 is installed at the bottom of each second sliding block 214, and a bolter is provided for each double-rotation mechanism 212. That is, the second sliding block 214 on the left is connected to the double-rotation mechanism 212 on the left, and the double-rotation mechanism 212 on the left is connected to the left bolter 210; the second sliding block 214 on the right is connected to the double-rotation mechanism 212 on the right, and the double-rotation mechanism 212 on the right is connected to the right bolter 211.

[0048] The double-rotation mechanism 212 includes a first hydraulic swing cylinder 222. The first hydraulic swing cylinder 222 is installed at the bottom of the second sliding block 214. The rotor of the first hydraulic swing cylinder 222 is connected to the second hydraulic swing cylinder 223 through a first mounting seat 233. The rotor of the second hydraulic swing cylinder 223 is connected to the bolter through a second mounting seat 234. The axis of the rotor of the first hydraulic swing cylinder 222 is in the X direction, and the axis of the rotor of the second hydraulic swing cylinder 223 is perpendicular to the axis of the rotor of the first hydraulic swing cylinder 222.

[0049] When the rotor of the first hydraulic swing cylinder 222 rotates, it drives the first mounting seat 233 to rotate. The first mounting seat 233 rotates synchronously with the second hydraulic swing cylinder 223, that is, the first mounting seat 233 and the second hydraulic swing cylinder 223 rotate synchronously around the X direction. When the rotor of the second hydraulic swing cylinder 223 rotates, it drives the second mounting seat 234 to rotate. The second mounting seat 234 rotates synchronously with the bolter, that is, the second mounting seat 234 and the bolter rotate along the axis direction of the rotor of the second hydraulic swing cylinder 223. In summary, the bolter can be adjusted at multiple angles and in multiple directions through the double-rotation mechanism 212, that is, the two most commonly used postures of the bolter are realized: the horizontal anchoring posture and the vertical anchoring posture; at the same time, the left bolter 210 and the right bolter 211 can operate separately, and have the function of realizing roof bolting and rib bolting operations simultaneously.

[0050] Reference Figures 4 - 6 As shown in FIGS. 5, 9, and 9, the sliding plate 215 is hinged to the bottom end of the fifth hydraulic cylinder 220, and the telescopic end of the fifth hydraulic cylinder 220 is hinged to the operating platform 209. The extension or shortening of the telescopic end of the fifth hydraulic cylinder 220 drives the operating platform 209 to unfold or fold. When the operating platform 209 is unfolded, it is for the operator to stand on to operate the equipment. After the operating platform 209 is folded, it is convenient for the equipment to move across the tunneling equipment 1.

[0051] Reference Figures 4 - 6 As shown in FIGS. 9 and 10, a temporary support mechanism 208 is provided at the top of the sliding frame 204; the temporary support mechanism 208 includes a sixth hydraulic cylinder 224 and a seventh hydraulic cylinder 238; the bottom end of the sixth hydraulic cylinder 224 is hinged to the connecting beam 218 on one side of the rear column 216, the telescopic end of the sixth hydraulic cylinder 224 is hinged to the lifting arm 241, the bottom end of the lifting arm 241 is hinged to the base 237, and the base 237 is fixed to the connecting beam 218 on the side of the front column 217; the top end of the lifting arm 241 is hinged to the support top frame 239; the bottom end of the seventh hydraulic cylinder 238 is hinged to the lifting arm 241, and the telescopic end of the seventh hydraulic cylinder 238 is hinged to the support top frame 239. Specifically, the lifting arm 241 is connected to the base 237 through the first hinge shaft 236. The support top frame 239 is connected to the lifting arm 241 through the second hinge shaft 240.

[0052] The extension or shortening of the telescopic end of the sixth hydraulic cylinder 224 drives the lifting arm 241 to rotate around the hinge shaft, realizing the rise and fall of the lifting arm 241 and the support top frame 239. The extension and shortening of the telescopic end of the seventh hydraulic cylinder 238 drive the support top frame 239 to swing and rotate around the hinge shaft to adjust the horizontal or inclination of the support top frame 239. Thus, the unfolding or folding of the temporary support mechanism 208 can be realized. When the temporary support mechanism 208 is unfolded, it is used for the temporary support of the bolting operation; when folded, it is convenient for the equipment to walk and move.

[0053] In summary, the bolt device 2 of the integrated tunneling and bolting operation device adopts a straddle structure, so it can cross the tunneling device 1 under the drive of the first crawler mechanisms 201 on both sides to perform bolt operations at the forefront of the roadway. The first crawler mechanisms 201 are driven by hydraulic motors 202 to travel, and can adapt to various pitted ground under the harsh environment of coal mine roadways. The gantries connected to the upper parts of the first crawler mechanisms 201 on both sides are firmly connected. The sliding frame 204 extends forward or retracts backward through the first sliding mechanism. The front end of the sliding frame 204 is provided with a lifting cross beam 213 that can move up and down through the second sliding mechanism, so that the bolt machine on the lifting cross beam 213 can perform roof bolting and rib bolting in roadways at different heights. The lifting cross beam 213 is provided with a second slider 214 that slides horizontally left and right, so that the bolt machine on the second slider 214 can perform roof bolting operations at different positions. A double rotation mechanism 212 is provided on the second slider 214, and the direction and angle of the bolt machine can be adjusted through the double rotation mechanism 212, so that a single bolt machine can simultaneously have the functions of roof bolting and rib bolting operations. The inner side of the sliding frame 204 is configured with a folding operation platform 209, which is convenient for personnel to operate the equipment and perform bolt operations. A temporary support mechanism 208 is provided on the upper part of the sliding frame 204. After the temporary support mechanism 208 extends out, it is used for temporary support of the roadway roof, enabling the operator to perform anchoring operations more safely.
