And then, carrying out fully mechanized mining operation by using a coal mining machine, a belt conveyor and the like, and simultaneously moving the coal mining machine and the belt conveyor outwards, so that the coal blocks mined by the coal mining machine are thrown onto the belt conveyor, and the belt conveyor sends the coal out of the roadway.

When fully-mechanized excavation is carried out, a transformer chamber needs to be excavated at intervals for placing a movable transformer and other auxiliary electromechanical equipment for power supply, and the problem of long-distance power supply of a fully-mechanized excavation working face is solved by adopting a method of timely moving the movable transformer and other auxiliary electromechanical equipment along with the advancement of excavation. When supporting materials required by various tunneling roadways need to be stored and placed, a temporary bracket platform is erected on a machine frame in the middle of the belt conveyor to place the supporting materials, and the supporting materials need to be erected, dismantled and moved repeatedly along with the extension of tunneling. With the extension of the tunneling, a large amount of manpower and material resources are consumed by repeated carrying and rebuilding work, the auxiliary operation time is increased, the tunneling starting operation time is shortened, and the improvement of the tunneling productivity is seriously restricted.

In the fully mechanized mining operation, currently, there is a method for realizing the timely relocation and movement of auxiliary electromechanical equipment by using an auxiliary electromechanical equipment rail train, which is roughly divided into two forms, namely a hanging rail type or a landing rail type. The two fully-mechanized mining methods both adopt the mode of running and working in parallel on a fully-mechanized mining working face belt gateway and the side of a belt conveyor.

When large equipment parts are transported in or out, the middle rack of the belt conveyor must be dismounted and then mounted, which is time-consuming and labor-consuming.

2. The two fully mechanized mining methods need to continuously remove the rails and sleepers behind the rail train of the auxiliary electromechanical equipment, and then manually carry and continue to connect to the front, so that the repetitive time consumption and a large amount of physical power consumption work are realized, the auxiliary operation time is invisibly prolonged, and the equipment starting rate is reduced.

A plurality of pairs of upright beams 7 are arranged along the length extension direction of the base 5, and two upright beams 7 in each pair of upright beams 7 are respectively arranged at two sides of the base 5. In order to transfer materials, a belt is wound on the fully mechanized mining hydraulic integrated equipment train and comprises an upper belt 10 and a lower belt 13 which are connected end to end.

The column beams 7 in the base unit 1 are of uniform height, so that the space between the base 5 of the base unit 1 and the upper idler beam frame 8 is relatively large.

Referring to fig. 1, the transition unit 2 comprises a first transition unit 21 and a second transition unit 22, referring to fig. 2 and 3, the height of the upper upright beam 7 of the first transition unit 21 is smaller than that of the upper upright beam 7 of the base unit 1, and along the length extension direction of the base 5 of the first transition unit 21, the height of the upright beam 7 is gradually reduced, so that the side of the upper idler beam frame 8 on the first transition unit 21, which is far away from the base unit 1, is inclined downwards.

Referring to fig. 3 and 4, the height of the upright beam 7 on the second transition unit 22 is smaller than that of the shortest upright beam 7 on the first transition unit 21, and the height of the upright beam 7 is gradually reduced along the length extension direction of the base 5 of the second transition unit 22, so that the side of the upper idler beam frame 8 on the second transition unit 22, which is far away from the second transition unit 22, is inclined downwards, 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.

Referring to fig. 5, the hydraulic power traveling unit 3 includes a traveling structure 31, the traveling structure 31 includes two parallel supporting guide rail traveling bottom beams 311, two parallel connecting rods 313 and a traveling structure frame 312 connected to two ends of the connecting rods 313, and the supporting guide rail traveling bottom beams 311 are slidably connected in the traveling structure frame 312.

Referring to fig. 5 and 6, a walking jack 314 is disposed in each walking structure frame 312, a hole is formed in a side wall of the walking structure frame 312 along the length extending direction of the supporting guide rail walking bottom beam 311, the walking jack 314 extends into the walking structure frame 312 through the hole, one end of the walking jack is hinged to the supporting guide rail walking bottom beam 311, the other end of the walking jack is hinged to the walking structure frame 312, and the extending direction of the walking jack 314 is parallel to the length extending direction of the supporting guide rail walking bottom beam 311. Therefore, when the walking jack 314 is extended, the walking structure frame 312 slides relative to the support rail walking bottom beam 311.

Referring to fig. 5 and 7, two sliding bars 315 are further disposed between the two walking structure frames 312, and the lifting structure 32 is slidably connected to the sliding bars 315. The lifting structure 32 includes a receiving frame 321 and a plurality of sliding rings 322 fixed on the bottom surface of the receiving frame 321, and two sliding rings 322 are provided on each sliding rod 315.

The lifting structure 32 further comprises a support 323 fixed to the center of the bottom surface of the receiving frame 321, and a traverse jack 33 is disposed between each of the two traveling structure frames 312 and the support 323. The bottom ends of the traverse jacks 33 are connected to a side of the traveling structure frame 312 near the support 323, and the output ends are connected to the support 323, so that the output ends of the two traverse jacks 33 are disposed to face each other, and the actions of the two traverse jacks 33 are opposite to each other, and when the output end of one of the traverse jacks 33 is extended, the output end of the other traverse jack 33 is retracted. The traverse jack 33 pushes the lifting structure 32 to slide laterally along the sliding bar 315.

Referring to fig. 5, the lifting structure 32 further includes four guiding posts 326 fixed on the receiving frame 321, the four guiding posts 326 surround to form a rectangle, and a rectangular ring frame 329 is fixed at the top end of the guiding posts 326. A lifting jack 325 is hinged to the bearing frame 321, a lifting frame 324 is hinged to the top end of the lifting jack 325, the lifting frame 324 slides in a rectangular ring frame 329, and the lifting frame 324 is limited by the rectangular ring frame 329, so that the stability is improved.

Two guide posts 326 on the same side of the lifting frame 324 are slidably connected with a connecting frame 327, and the connecting frame 327 is fixed at the bottom end of the lifting frame 324. Thus, when the output end of the lifting jack 325 is extended, the lifting frame 324 is lifted in the vertical direction along the guide posts 326.

Referring to fig. 2 and 5, a mounting shaft 328 is connected to each end of the connecting frame 327, two connecting frames 15 are fixed to each end of the receiving frame 321 of the base unit 1 or the transition unit 2, and one end of each connecting frame 15, which is far away from the base 5, is hinged to the mounting shaft 328, so that the hydraulic power traveling unit 3 is connected to the adjacent base unit 1 or the transition unit 2.

Referring to fig. 1 and 5, the weight of the base unit 1 or the transition unit 2 connected to both sides of the hydraulic power traveling unit 3 may be different, however, since the lifting frame 324 slides in the vertical direction along the four guide posts 326, the lifting frame 324 is always kept horizontal during lifting, and thus the base unit 1 or the transition unit 2 lifted by the lifting frame 324 can be lifted simultaneously, and the base unit 1 and the transition unit 2 move synchronously at the same speed during lifting. Meanwhile, the lifting frame 324 bears the radial force applied to the hydraulic power walking unit 3, and the lifting frame 324 is hinged to the lifting jack 325, so that the radial force applied to the lifting jack 325 is reduced.

Referring to fig. 1 and 5, when it is required to move the fully mechanized mining hydraulic integrated equipment train, the output end of the lifting jack 325 is firstly extended to push the lifting frame 324 and the connecting frame 327 to be lifted, the two ends of the base unit 1 and the transition unit 2 are lifted by the connecting frame 15, and the support leg 6 of the base unit 1 and the transition unit 2 leaves the ground; then the output end of the walking jack 314 extends, the walking structure frame 312 slides along the supporting guide rail walking bottom beam 311, the walking structure frame base 312 also translates along with the walking structure frame base 312, and therefore the basic unit 1 and the transition unit 2 connected with the walking structure frame base 312 also translate, namely, the fully-mechanized mining hydraulic integrated equipment train integrally moves for a certain distance.

At the moment, the transverse moving jack 33 can be driven to act to pull the basic unit 1 and the transition unit 2 to move transversely, so that the positions of the basic unit 1 and the transition unit 2 are convenient to adjust, the upper belt 10 is positioned in the center of the upper belt carrier roller 9, and the lower belt 13 is positioned in the center of the lower belt carrier roller 12.

After a certain walking distance is finished, the output end of the lifting jack 325 is driven to retract, so that the support legs 6 of the base unit 1 and the transition unit 2 are in contact with the ground, then the output end of the lifting jack 325 continues to retract, the positions of the lifting frame 324 and the connecting frame 327 are not moved under the support of the connecting frame 15, the supporting guide rail walking bottom beam 311 is lifted from the ground, then the output end of the walking jack 314 retracts, and the supporting guide rail walking bottom beam 311 returns to be ready for the next walking. When the user needs to continue walking, the output end of the lifting jack 325 is driven to extend, so that the supporting guide rail walking bottom beam 311 is in contact with the ground, and the actions are repeated.

Two lower belt rollers 12 with parallel axes are also arranged between the two running gear frames 312, and the lower belt 13 is conveyed on the lower belt rollers 12.

Referring to fig. 1 and 8, the transition unit 2 further includes a third transition unit 23, and the third transition units 23 are disposed at two ends of the fully-mechanized mining hydraulic integrated equipment train in a group. The third transition unit 23 is provided on the hydraulic power traveling unit 3 on the side of the second transition unit 22 away from the first transition unit 21, the boom frame base 231, and the boom frame 232. The cantilever frame base 231 is fixed on the lifting frame 324 of the hydraulic power traveling unit 3 located on the side of the second transition unit 22 away from the first transition unit 21, the first support 233 and the second support 234 are fixed at two ends of the connecting frame 327, and when the output end of the height-adjusting jack 235 is in the retracted state, the cantilever frame base 231 is supported on the first support 233 and the second support 234, so that the stability of the cantilever frame base 231 is improved.

A plurality of groups of upper belt carrier rollers 9 are also fixed on the cantilever frame 232, and the upper belt 10 is driven on the upper belt carrier rollers 9.

One end of the cantilever frame 232 is hinged with the cantilever frame base 231, one end of the second support 234 close to the cantilever frame 232 is hinged with an elevation jack 235, and the output end of the elevation jack 235 is hinged with the bottom surface of the cantilever frame 232. When the height-adjusting jack 235 acts, the cantilever frame 232 rotates around the axis hinged to the cantilever frame base 231, and 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. Because belt conveyors are generally arranged at the head end and the tail end of the equipment train, and a height difference exists between the belt conveyors and the second transition unit 22, when the upper belt 10 moves from the second transition unit 22 to the belt conveyors, the fall is large, and the transportation of the upper belt 10 is unstable. The inclination of the cantilever frame 232 can be adjusted to stably engage the upper belt 10 between the second transition unit 22 and the belt conveyor, so that the upper belt 10 is smoothly transferred.

As the space above the basic unit 1 is large, auxiliary electromechanical equipment such as a movable transformer, various control switches, an emulsion pump, an emulsion tank, an emulsion water purification and softening device, a drainage pump and the like are arranged on a base 5 of the basic unit 1. The first transition unit 21 has a smaller space, and the base 5 of the first transition unit 21 is used for bearing and placing a power supply cable, an emulsion pump, a water pump or spare parts with larger volume or under replacement for fully-mechanized mining, pre-extending, hoisting, or fully-mechanized mining recovery. The space above the second transition unit 22 is minimal and therefore the base 5 of the second transition unit 22 is used to carry spare parts for placement of a water pump, smaller volume or replacement. A plurality of pipeline hooks 14 are arranged on one side of the upright post beam 7, and cables, liquid pipes and water pipes can be hung on the pipeline hooks 14.

When the fully-mechanized mining hydraulic integrated equipment train moves along with the fully-mechanized mining propulsion or the fully-mechanized mining recovery, various power supply equipment, power equipment, maintenance devices, various supporting materials and the like are carried at any time, the preparation time for carrying and constructing the equipment is shortened, the labor intensity of fully-mechanized mining auxiliary operation is reduced, the auxiliary operation time is shortened, the overhaul and the maintenance are convenient, and the working efficiency is improved.

The upper belt 10 and the lower belt 13 are connected with the basic unit 1 and the transition unit 2, and occupy the inherent vertical and horizontal spaces of the belt conveyor, so that the maximum promotion of limited space utilization is realized, and operating personnel and auxiliary transport vehicles can smoothly pass through the belt conveyor. The spacious space that the integral type design released, each item operation such as the advance support of being convenient for, daily maintenance goes on safely smoothly, has laid good environment and material basis for combining the digging propulsion, the combined mining stope auxiliary work.

A plurality of three-way shut-off valves 43 are connected to the return line 412, and are each configured to receive hydraulic oil or emulsion flowing back from each of the hydraulic power traveling units 3. The hydraulic oil or high-pressure emulsion that flows back in the hydraulic power traveling unit 3 is communicated to the one-way oil inlet end of the liquid return three-way shut-off valve 43, the liquid return pipeline 412 is communicated with the oil outlet end of the liquid return three-way shut-off valve 43, and the other normally open oil inlet end of the liquid return three-way shut-off valve 43 is connected to the oil outlet end of the adjacent liquid return three-way shut-off valve 43.
