Description

Technical Field

[0001] The present application relates to the field of comprehensive excavation and mining equipment in the mining industry, and in particular to a comprehensive excavation and mining hydraulic integrated equipment train. Background Art

[0002] In the process of coal mining, tunneling machines and belt conveyors are used for comprehensive mining operations. The tunneling machine digs in and out of the tunnel, and the excavated gravel is placed on the belt conveyor, which transports the gravel out of the tunnel to facilitate the smooth progress of comprehensive mining. Then, coal mining machines and belt conveyors are used for comprehensive mining operations, while moving out of the tunnel. The coal blocks mined by the coal mining machine are placed on the belt conveyor, which transports the coal out of the tunnel.

[0003] When conducting comprehensive excavation operations, it is necessary to open up transformer chambers every certain distance of excavation to place mobile transformers and other auxiliary electromechanical equipment for power supply. As excavation progresses, the method of timely relocation of mobile transformers and other auxiliary electromechanical equipment is adopted to solve the problem of long-distance power supply of the comprehensive excavation working face. When it is necessary to store and place the supporting materials required for various excavation tunnels, a temporary bracket platform is set up on the middle frame of the belt conveyor to place the supporting materials. As the excavation extends, it needs to be repeatedly set up, dismantled, and relocated. As the excavation extends, repeated transportation and reconstruction work consumes a lot of manpower and material resources, increases the auxiliary operation time, shortens the excavation start-up operation time, and seriously restricts the improvement of excavation productivity.

[0004] When conducting comprehensive mining operations, there is currently a method of using auxiliary electromechanical equipment rail trains to achieve timely relocation of auxiliary electromechanical equipment, which is generally divided into two forms: hanging rail type or ground rail type. Both comprehensive mining methods are operated in parallel in the belt chute lane of the comprehensive mining working face and beside the belt conveyor. The following problems may exist:

[0005] 1. The two comprehensive mining methods occupy the already narrow tunnel space, making it impossible for auxiliary transport vehicles to pass through; the middle frame of the belt conveyor within the entire length of the auxiliary electromechanical equipment rail train must be removed to allow the auxiliary transport vehicle to pass. Every time a large equipment component is transported in or out, the middle frame of the belt conveyor must be removed and then installed, which is time-consuming and laborious.

[0006] 2. Both comprehensive mining methods require continuous removal of the tracks and sleepers behind the auxiliary electromechanical equipment rail train, and then manual transportation and connection to the front. Such repetitive, time-consuming and physically demanding work virtually prolongs the auxiliary operation time and reduces the equipment startup rate.

[0007] Regarding the related technologies mentioned above, the inventor believes that the auxiliary work in current full-mechanized tunneling and coal winning is cumbersome, and continuous manual relocation operations are required to enable normal tunneling and coal winning operations, resulting in low labor productivity. Summary of the Invention

Detailed implementation manners

[0055] The following further elaborates on this application in conjunction with the attached Figures 1-11 drawings for a more detailed description.

[0056] An embodiment of this application discloses a fully-mechanized tunneling and mining integrated hydraulic equipment train. Referring to Figure 1 , the fully-mechanized tunneling and mining integrated hydraulic equipment train includes a basic unit 1, a transition unit 2, and a hydraulic power walking unit 3.

[0057] Referring to Figure 1 and Figure 2, the basic unit 1 is arranged in the center of the integrated fully-mechanized heading and coal winning hydraulic equipment train, and multiple basic units 1 can be arranged according to requirements. The transition units 2 are respectively arranged on both sides of the basic unit 1, and with the basic unit 1 as the center, the height of the transition units 2 gradually decreases as they extend to both sides. Both the basic unit 1 and the transition unit 2 include a base 5, and feet 6 are arranged at the bottom of the base 5. The feet 6 directly support on the roadway floor of fully-mechanized heading or coal winning, without laying tracks, so the operation time occupied by removing, transporting and reconnecting sleeper tracks is saved, and the work efficiency is improved. At the same time, compared with setting tracks, the feet 6 directly contact the roadway floor, increasing the frictional resistance between the feet 6 and the roadway floor. When encountering a roadway section with a large slope, the possibility of slipping is reduced, and the safety is improved.

[0058] A plurality of pairs of column beams 7 are arranged along the length extension direction of the base 5, and the two column beams 7 in each pair of column beams 7 are respectively arranged on both sides of the base 5. In order to transport materials, a belt is wound around the integrated fully-mechanized heading and coal winning hydraulic equipment train. The belt includes an upper belt 10 and a lower belt 13 that are connected end to end. An upper idler beam frame 8 is fixed on the top of the column beam 7, and multiple groups of upper belt idlers 9 are fixed on the upper idler beam frame 8. The upper belt 10 is conveyed on the upper belt idlers 9, and the ore or coal mined at the fully-mechanized coal winning or heading working face is conveyed out through the upper belt 10. A lower idler beam frame 11 is fixed below the base 5, and multiple groups of lower belt idlers 12 are rotatably connected to the lower idler beam frame 11. The lower belt 13 is conveyed on the lower belt idlers 12. After the upper belt 10 sends out the coal or ore, the lower belt 13 turns back from below the base 5.

[0059] The heights of the column beams 7 in the basic unit 1 are the same, so the space between the base 5 and the upper idler beam frame 8 of the basic unit 1 is relatively large.

[0060] Refer to Figure 1 , the transition unit 2 includes a first transition unit 21 and a second transition unit 22. Refer to Figure 2 and Figure 3 , the heights of the upper column beams 7 of the first transition unit 21 are all less than the heights of the upper column beams 7 of the basic unit 1, and along the length extension direction of the base 5 of the first transition unit 21, the height of the column beam 7 gradually decreases. Therefore, the side of the upper idler beam frame 8 on the first transition unit 21 far from the basic unit 1 inclines downward.

[0061] Refer to Figure 3 and Figure 4, the height of the upright beams 7 on the second transition unit 22 is less than that of the shortest upright beam 7 on the first transition unit 21, and along the length extension direction of the base 5 of the second transition unit 22, the height of the upright beam 7 gradually decreases. Therefore, the side of the upper idler beam frame 8 on the second transition unit 22 away from the second transition unit 22 slopes downward, and the inclination angles of the upper idler beam frames 8 of the second transition unit 22 and the first transition unit 21 are the same. Therefore, when the upper belt 10 is conveyed above the first transition unit 21 and the second transition unit 22, the inclination of the upper belt 10 is consistent, improving the stability of conveying materials.

[0062] Refer to Figure 1 , there are multiple hydraulic power walking units 3, which are respectively arranged between two adjacent basic units 1, between the basic unit 1 and the first transition unit 21, between the first transition unit 21 and the second transition unit 22, and on the side of the second transition unit 22 away from the first transition unit 21.

[0063] Refer to Figure 5 , the hydraulic power walking unit 3 includes a walking structure 31. The walking structure 31 includes two parallel support guide walking bottom beams 311, and also includes two parallel connecting rods 313 and a walking structure frame 312 connected to both ends of the connecting rod 313. The support guide walking bottom beam 311 is slidably connected within the walking structure frame 312.

[0064] Refer to Figure 5 and Figure 6 , a walking jack 314 is arranged within each walking structure frame 312. A hole is opened on the side wall of the walking structure frame 312 along the length extension direction of the support guide walking bottom beam 311. The walking jack 314 extends into the walking structure frame 312 through the hole, with one end hinged to the support guide walking bottom beam 311 and the other end hinged to the walking structure frame 312. The extending direction of the walking jack 314 is parallel to the length extension direction of the support guide walking bottom beam 311. Therefore, when the walking jack 314 extends, the walking structure frame 312 and the support guide walking bottom beam 311 slide relative to each other.

[0065] Refer to Figure 5 and Figure 7 , two sliding rods 315 are further arranged between the two walking structure frames 312, and a lifting structure 32 is slidably connected to the sliding rods 315. The lifting structure 32 includes a receiving frame 321 and a plurality of sliding rings 322 fixed to the bottom surface of the receiving frame 321. Two sliding rings 322 are arranged on each sliding rod 315.

[0066] The lifting structure 32 further includes a support 323 fixed to the center of the bottom surface of the receiving frame 321. A transverse jack 33 is provided between each of the two walking structure frames 312 and the support 323. The bottom end of the transverse jack 33 is connected to one side of the walking structure frame 312 close to the support 323, and the output end is connected to the support 323. Therefore, the output ends of the two transverse jacks 33 are arranged facing each other, and the actions of the two transverse jacks 33 are opposite. When the output end of one transverse jack 33 extends, the output end of the other transverse jack 33 retracts. Therefore, the transverse jack 33 pushes the lifting structure 32 to slide laterally along the slide bar 315.

[0067] Referring to Figure 5 , the lifting structure 32 further includes four guide columns 326 fixed to the receiving frame 321. The four guide columns 326 enclose a rectangle, and a rectangular ring frame 329 is fixed to the top ends of the guide columns 326. A lifting jack 325 is hinged to the receiving frame 321. The top end of the lifting jack 325 is hinged to a lifting frame 324. The lifting frame 324 slides within the rectangular ring frame 329, and the rectangular ring frame 329 limits the lifting frame 324 to improve stability.

[0068] A connecting frame 327 is slidably connected to two guide columns 326 on the same side of the lifting frame 324. The connecting frame 327 is fixed to the bottom end of the lifting frame 324. Therefore, when the output end of the lifting jack 325 extends, the lifting frame 324 is lifted vertically along the guide columns 326.

[0069] Referring to Figure 2 and Figure 5 , an installation shaft 328 is connected to each end of the connecting frame 327. Two connecting brackets 15 are fixed to each end of the receiving frame 321 of the basic unit 1 or the transition unit 2. The end of the connecting bracket 15 far from the base 5 is hinged to the installation shaft 328. Therefore, the hydraulic power walking unit 3 is connected to the adjacent basic unit 1 or transition unit 2.

[0070] Referring to Figure 1 and Figure 5 , the weights of the basic unit 1 or the transition unit 2 connected to both sides of the hydraulic power walking unit 3 may not be the same. However, since the lifting frame 324 slides vertically along the four guide columns 326, the lifting frame 324 always remains horizontal during the lifting process. Therefore, the basic unit 1 or the transition unit 2 lifted by the lifting frame 324 can be lifted simultaneously, and the basic unit 1 and the transition unit 2 move synchronously and at the same speed during the lifting process. At the same time, the lifting frame 324 bears the radial force received by the hydraulic power walking unit 3, and the lifting frame 324 is hinged to the lifting jack 325, reducing the radial force on the lifting jack 325.

[0071] Referring to Figure 1 andFigure 5 When it is necessary to move the fully hydraulic integrated equipment train for fully mechanized tunneling and coal winning, first, the output end of the lifting jack 325 extends, pushing the lifting frame 324 and the connecting frame 327 to rise. Both ends of the basic unit 1 and the transition unit 2 are supported by the connecting frame 15, and the feet 6 of the basic unit 1 and the transition unit 2 leave the ground. Then, the output end of the traveling jack 314 extends, and the traveling structure frame 312 slides along the supporting guide rail traveling bottom beam 311. The traveling structure frame 312 also translates accordingly. Therefore, the basic unit 1 and the transition unit 2 connected to the traveling structure frame 312 also translate, that is, the fully hydraulic integrated equipment train for fully mechanized tunneling and coal winning moves a certain distance as a whole.

[0072] At this time, the transverse movement jack 33 can also be driven to pull the basic unit 1 and the transition unit 2 to move horizontally, facilitating the adjustment of the positions of the basic unit 1 and the transition unit 2, so that the upper belt 10 is centered on the upper belt idler 9, and the lower belt 13 is centered on the lower belt idler 12.

[0073] When a certain traveling distance is completed, the output end of the lifting jack 325 is retracted to make the feet 6 of the basic unit 1 and the transition unit 2 contact the ground. Then, the output end of the lifting jack 325 continues to retract. Under the support of the connecting frame 15, the positions of the lifting frame 324 and the connecting frame 327 remain unchanged, and the supporting guide rail traveling bottom beam 311 is lifted from the ground. Then, the output end of the traveling jack 314 is retracted, and the supporting guide rail traveling bottom beam 311 returns to its original position to prepare for the next travel. When it is necessary to continue traveling, the output end of the lifting jack 325 is extended to make the supporting guide rail traveling bottom beam 311 contact the ground, and the above actions can be repeated.

[0074] There are also two lower belt idlers 12 with parallel axes arranged between the two traveling structure frames 312, and the lower belt 13 is conveyed on the lower belt idlers 12.

[0075] Refer to Figure 1 and Figure 8 , the transition unit 2 further includes a third transition unit 23, and a set of the third transition unit 23 is arranged at each end of the fully hydraulic integrated equipment train for fully mechanized tunneling and coal winning. The third transition unit 23 is arranged on the hydraulic power traveling unit 3 on the side of the second transition unit 22 away from the first transition unit 21, including a cantilever frame base 231 and a cantilever frame 232. The cantilever frame base 231 is fixed on the lifting frame 324 of the hydraulic power traveling unit 3 on the side of the second transition unit 22 away from the first transition unit 21. A first support 233 and a second support 234 are respectively fixed at both ends of the connecting frame 327. When the output end of the height adjustment jack 235 is in the retracted state, the cantilever frame base 231 is supported on the first support 233 and the second support 234, improving the stability of the cantilever frame base 231.

[0076] A number of groups of upper belt rollers 9 are also fixed on the cantilever frame 232, and the upper belt 10 is driven on the upper belt rollers 9.

[0077] One end of the cantilever frame 232 is hinged to the cantilever frame base 231. A height-adjusting jack 235 is hinged to one end of the second support 234 close to the cantilever frame 232, and the output end of the height-adjusting jack 235 is hinged to the bottom surface of the cantilever frame 232. When the height-adjusting jack 235 operates, the cantilever frame 232 rotates around the axis hinged to the cantilever frame base 231. When the output end of the height-adjusting jack 235 extends, the included angle between the cantilever frame 232 and the horizontal line decreases, that is, the inclination of the cantilever frame 232 decreases. Since belt conveyors are generally arranged at both the head and the tail of the equipment train, and there is a height difference between the belt conveyor and the second transition unit 22, when the upper belt 10 moves from the second transition unit 22 to the belt conveyor, the drop is large and the transportation of the upper belt 10 is unstable. Therefore, the inclination of the cantilever frame 232 can be adjusted to stably connect the upper belt 10 between the second transition unit 22 and the belt conveyor, so that the upper belt 10 is smoothly conveyed.

[0078] Since there is a large space on the basic unit 1, auxiliary electromechanical equipment such as mobile transformers, various control switches, emulsion pumps, emulsion tanks, emulsion water purification and softening devices, and drainage pumps are placed on the base 5 of the basic unit 1. The space of the first transition unit 21 is small, and the base 5 of the first transition unit 21 is used to carry and place the power supply cables for fully-mechanized tunneling pre-extension and hanging or fully-mechanized mining recovery, emulsion pumps, water pumps, or large-sized spare parts or replaced spare parts. The space on the second transition unit 22 is the smallest. Therefore, the base 5 of the second transition unit 22 is used to carry and place water pumps, small-sized spare parts or replaced spare parts. A plurality of pipeline hooks 14 are arranged on one side of the column beam 7, and cables, liquid pipes and water pipes can be hung on the pipeline hooks 14.

[0079] Refer to Figure 10 and Figure 11 , when the fully-mechanized tunneling and fully-mechanized mining hydraulic integrated equipment train moves with the advancement of fully-mechanized tunneling or the retreat of fully-mechanized mining, it can carry various power supply equipment, power equipment, maintenance devices and various support materials at any time, shortening the preparation time for handling and erecting equipment, reducing the labor intensity of fully-mechanized tunneling auxiliary operations, shortening the auxiliary operation time, facilitating overhaul and maintenance, and improving work efficiency.

[0080] The upper belt 10 and the lower belt 13 are connected to the basic unit 1 and the transition unit 2, occupying the inherent vertical and horizontal space of the belt conveyor, maximizing the limited utilization of the cramped space, and enabling the operators and auxiliary transport vehicles to pass smoothly. The spacious space released by the integrated design facilitates the safe and smooth progress of various operations such as advanced support and daily maintenance, laying a good environmental and material foundation for the auxiliary work of fully-mechanized tunneling advancement and fully-mechanized mining retreat.

[0081] Reference Figure 9 Figure 9 , the fully - mechanized tunneling and mining hydraulic integrated equipment train further includes a hydraulic transmission control system 4, which is used to control the execution of the overall lifting, walking, descending, retracting the support guide walking bottom beam 311, and left - right adjustment in the horizontal direction of 6 actions of the fully - mechanized tunneling and mining hydraulic integrated equipment train, or separately manually hydraulically control a certain unit to execute lifting, descending, and left - right adjustment movement in the horizontal direction.

[0082] The hydraulic transmission control system 4 includes a hydraulic pipeline 41 connected to the power component. The power component feeds hydraulic oil or high - pressure emulsion into the hydraulic pipeline 41, and the power component can be a hydraulic pump. The hydraulic pipeline 41 includes a liquid inlet pipeline 411 and a liquid return pipeline 412. A plurality of liquid inlet four - way ball valves 42 are connected to the liquid inlet pipeline 411. The liquid inlet pipeline 411 is connected to the liquid inlet end of the liquid inlet four - way ball valve 42. One of the liquid outlet ends of the liquid inlet four - way ball valve 42 is connected to the hydraulic power walking unit 3 connected to the current liquid inlet four - way ball valve 42, and the other liquid outlet end of the liquid inlet four - way ball valve 42 is connected to the liquid inlet end of the adjacent liquid inlet four - way ball valve 42.

[0083] A plurality of liquid return three - way cut - off valves 43 are connected to the liquid return pipeline 412, and are all used to receive the hydraulic oil or emulsion flowing back from each hydraulic power walking unit 3. The hydraulic oil or high - pressure emulsion flowing back in the hydraulic power walking unit 3 is all connected to the one - way oil inlet end of the liquid return three - way cut - off valve 43. The liquid return pipeline 412 is connected to the oil outlet end of the liquid return three - way cut - off valve 43, and the other normally - open oil inlet end of the liquid return three - way cut - off valve 43 is connected to the oil outlet end of the adjacent liquid return three - way cut - off valve 43.

[0084] Therefore, each liquid inlet four - way ball valve 42 is used to control the individual action of each hydraulic power walking unit 3. If all the hydraulic power walking units 3 are to act simultaneously, that is, all the liquid inlet four - way ball valves 42 are opened simultaneously.

[0085] The hydraulic transmission control system 4 further includes an electric control four - way reversing valve group 44. The electric control four - way reversing valve group 44 includes a plurality of electric three - position four - way reversing valves, including a first reversing valve 441, a second reversing valve 442, a third reversing valve 443, and a fourth reversing valve 444. The lifting jack 325, the transverse movement jack 33, and the walking jack 314 in the hydraulic power walking unit 3 are respectively connected to an electric three - position four - way reversing valve. The oil inlet ports of the electric three - position four - way reversing valves are all connected to the liquid outlet end of the liquid inlet four - way ball valve 42, and the oil outlet ports of the electric three - position four - way reversing valves are all connected to the one - way oil inlet end of the liquid return three - way cut - off valve 43.

[0086] The hydraulic transmission control system 4 further includes a plurality of safety valves 46, including a first safety valve 461, a second safety valve 462, and a third safety valve 463. The safety valve 46 is used to control the pressure balance and stability of the medium in the pipeline.

[0087] The bottom end of the lifting jack 325 is connected to a first safety valve 461. The first safety valve 461 is connected to the oil outlet of a one-way valve 45. A first reversing valve 441 is used to control the lifting jack 325. One working end of the first reversing valve 441 is simultaneously connected to the head end of the lifting jack 325 and the control oil port of the one-way valve 45, and the other working end is connected to the oil inlet of the one-way valve 45.

[0088] Therefore, when driving the output end of the lifting jack 325 to extend, the first reversing valve 441 is switched, so that hydraulic oil or emulsion enters from the oil inlet of the one-way valve 45. The one-way valve 45 is conducted, and the hydraulic oil or emulsion pushes the output end of the lifting jack 325 to extend. The returned hydraulic oil or emulsion flows back from the head end of the lifting jack 325 to the first reversing valve 441. When driving the output end of the height-adjusting jack 235 to retract, the first reversing valve 441 is switched, so that the hydraulic oil or emulsion drives the lifting jack 325 to return to its position and the one-way valve 45 is conducted, and the returned hydraulic oil and emulsion flow back to the first reversing valve 441 through the one-way valve 45. And when the control oil port of the one-way valve 45 is closed, it conducts in one direction to prevent the hydraulic oil or emulsion entering the lifting jack 325 from flowing back, improving the stability of hydraulic control.

[0089] The hydraulic transmission control system 4 further includes a plurality of hydraulic two-way locks 47. The hydraulic two-way locks 47 are composed of two one-way valves in combination, including a first hydraulic two-way lock 471, a second hydraulic two-way lock 472, and a third hydraulic two-way lock 473.

[0090] Both of the two traversing jacks 33 are connected to the first hydraulic two-way lock 471. One working end of a second reversing valve 442 for controlling the traversing jack 33 is connected to the oil inlet of the first one-way valve and the control oil port of the second one-way valve of the first hydraulic two-way lock 471; the other working end is connected to the oil inlet of the second one-way valve and the control oil port of the first one-way valve of the first hydraulic two-way lock 471. The oil outlet of the first one-way valve is connected to the head end of the first traversing jack 33 and the tail end of the second traversing jack 33, and the oil outlet of the second one-way valve is connected to the tail end of the first traversing jack 33 and the head end of the second traversing jack 33. A second safety valve 462 is connected between the oil outlet of one of the one-way valves and the traversing jack 33.

[0091] Therefore, when the transverse jack 33 is driven to act, the second reversing valve 442 is switched, so that hydraulic oil or emulsion enters from the oil inlet of the first one-way valve, the first hydraulic double-lock 471 is conducted, and the hydraulic oil or emulsion drives the first transverse jack 33 to return to its original position, while the second transverse jack 33 extends. Thus, the walking structure frame base 312 is transversely moved in a certain direction. At the same time, the hydraulic oil or emulsion flowing out of the transverse jack 33 flows back to the second reversing valve 442. When the walking structure frame base 312 is transversely moved in the other direction, the electric second reversing valve 442 is switched, so that hydraulic oil or emulsion enters from the oil inlet of the second one-way valve. When the control oil port of the first hydraulic double-lock 471 is closed, it conducts unidirectionally, preventing the hydraulic oil or emulsion entering the transverse jack 33 from flowing back, and improving the stability of hydraulic control.

[0092] Both of the two walking jacks 314 are connected to the second hydraulic double-lock 472. The third reversing valve 443 is used to control the walking jacks 314. One working end of the third reversing valve 443 is connected to the oil inlet of the first one-way valve and the control oil port of the second one-way valve of the second hydraulic double-lock 472, and the other working end is connected to the oil inlet of the second one-way valve and the control oil port of the first one-way valve of the second hydraulic double-lock 472. The oil outlet of the first one-way valve is connected to the tail ends of the two walking jacks 314, and the oil outlet of the second one-way valve is connected to the head ends of the two walking jacks 314. A third safety valve 463 is connected between one of the oil outlets and the walking jack 314.

[0093] Therefore, when the walking jack 314 is driven to extend, the third reversing valve 443 is switched, so that hydraulic oil or emulsion enters from the oil inlet of the first one-way valve, the second hydraulic double-lock 472 is conducted, and the hydraulic oil or emulsion drives the walking jack 314 to extend. At the same time, the refluxed hydraulic oil or emulsion flows back to the second hydraulic double-lock 472. When the walking jack 314 is driven to return to its original position, the third reversing valve 443 is switched, so that hydraulic oil or emulsion enters from the oil inlet of the second one-way valve. When the control oil port of the second hydraulic double-lock 472 is closed, it conducts unidirectionally, preventing the hydraulic oil or emulsion entering the walking jack 314 from flowing back, and improving the stability of hydraulic control.

[0094] Since a height-adjusting jack 235 is also provided in the third transition unit 23, the electric four-way reversing valve group 44 in the third transition unit 23 includes a fourth reversing valve 444 for controlling the height-adjusting jack 235, and also includes a connected fourth safety valve 464 and a third hydraulic double-lock 373. The connection relationship among the height-adjusting jack 235, the fourth reversing valve 444, the fourth safety valve 464, and the third hydraulic double-lock 373 is the same as the connection relationship of the hydraulic control components for controlling the walking jack 314.

[0095] The implementation principle of an integrated fully-mechanized tunneling and coal mining hydraulic equipment train in an embodiment of this application is as follows:

[0096] When using the integrated fully-mechanized tunneling and coal mining hydraulic equipment train for tunneling work, a roadheader and a belt conveyor for transferring materials, etc. are arranged on one side of the integrated fully-mechanized tunneling and coal mining hydraulic equipment train close to the tunneling face. The belt is wound around the receiving part of the tail of the belt conveyor. The belt conveyor transfers the materials onto the upper belt 10, and the materials are conveyed out of the excavated roadway.

[0097] When using the integrated fully-mechanized tunneling and coal mining hydraulic equipment train for coal mining work, a shearer and a belt conveyor for transferring materials, etc. are arranged on one side of the integrated fully-mechanized tunneling and coal mining hydraulic equipment train close to the coal mining face. The belt is wound around the receiving part of the tail of the belt conveyor. The belt conveyor transfers the materials onto the upper belt 10, and the materials are conveyed out of the excavated roadway.

[0098] After installing the upper belt 10 on the upper belt roller 9, the lifting jack 325 can be driven to act, so that the upper belt 10 is stably supported.

[0099] When the equipment train moves, the output end of the lifting jack 325 is driven to extend, so that the feet 6 of the basic unit 1 and the transition unit 2 leave the ground. Then the walking jack 314 is driven to extend, so that the basic unit 1 and the transition unit 2 are translated simultaneously. If it is necessary to horizontally adjust the positions of the basic unit 1 and the transition unit 2, the transverse movement jack 33 is driven.

[0100] Then the output end of the lifting jack 325 is driven to retract, so that the feet 6 of the basic unit 1 and the transition unit 2 support on the ground. Then the driving lifting jack 325 is continuously retracted, the supporting guide rail walking bottom beam 311 is lifted, and finally the output end of the walking jack 314 is retracted.

[0101] If continuing to move, the above actions are repeated.

[0102] The above are all preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
