[0002] The conveying system is an essential link in the underground coal production operation process. The reasonable layout of the conveying system directly affects the advancing speed of coal mining work, the operating cost of the mining area, and the working intensity and working environment of underground operating personnel. At present, the fully mechanized coal mining team in coal mines can cut coal up to more than 20 cuts a day and advance more than 16 meters. Moreover, with the development of high-end coal mining equipment and the needs of coal mining, the advancing speed of the fully mechanized coal mining face will further increase. The increase in the advancing speed of the fully mechanized coal mining face has led to the inability of the original method of manually removing some belt racks at one time to meet the advancing needs. It is necessary for the production shift to disassemble the belt racks multiple times, which seriously affects the production progress and mining efficiency, increases the operating cost and the working intensity of underground operating personnel, and there are serious safety hazards.

[0003] However, the existing belt racks of conveyors are only adapted to coal mine roadways with fixed sizes during use, so that the use range of the entire device is small. At the same time, when the existing belt racks convey materials, the belt will deviate from the idlers inside the bracket due to belt friction, resulting in poor stability of the entire device.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] (1) By rotating the main telescopic frame of the present invention, the outer telescopic frame and the inner telescopic frame can be driven to expand and contract, thereby changing the distance between the two positioning frames, thereby changing the distance between the ordinary column and the lifting column, so as to adapt to coal mine roadways of different sizes, thereby improving the usage range of the entire device. At the same time, through the expansion and contraction of the lifting rod, the support inside the lifting column can be driven to rise and fall, so that the height of the supports in the roadway is the same, so that the belt is kept horizontal, thus ensuring the coal conveying effect. At the same time, due to the function of the ordinary column, some supports of the device do not need to be controlled, thus saving resources. The device can quickly, efficiently and stably complete the extension and contraction of the whole machine, realizing the long-distance lapping of the belt conveyor and the self-advancing tail after the belt conveyor belt rack in the fully mechanized mining face is removed. At the same time, through the unique design of structures such as the telescopic fuselage column and the telescopic frame of the present invention, the influence of the unevenness of the roadway floor on the fuselage is eliminated, and the speed and stability of the telescopic process are improved. The present invention completely solves the problem of discontinuous production in the production shift, ensures production continuity, improves production progress and mining efficiency, reduces operating costs and the labor intensity of workers, improves production safety, and is widely applicable to various fully mechanized mining mines;

[0017] (2) By the expansion and contraction of the anti-disengagement rod of the present invention, the anti-disengagement frame can be driven to move up and down, thereby driving the baffle to rise and fall, so as to position the height of the belt, thereby preventing the belt from warping, thus ensuring the safety of the belt. Through the cooperation of the anti-disengagement strip and the anti-disengagement spring of the device, the anti-disengagement plate can be made to be in close contact with the positioning frame, so as to prevent the belt from shifting, thus ensuring the stability of the entire device during coal conveying;

[0018] (3) By the locking rod being clamped into the adjusting rod, the stability of the adjusting rod can be ensured. At the same time, through the cooperation of the locking spring and the positioning strip of the device, the locking plate can be made to approach the positioning strip, so that the locking rod has a force to approach the adjusting rod, thus ensuring the stability of the adjusting rod while facilitating disassembly. At the same time, through the expansion and contraction of the adapting rod, the adapting plate can be driven to move up and down, thereby driving the support inside the vehicle frame to rise and fall, so that the vehicle frame can control the height inside the vehicle frame according to the height of the conveyor, thus improving the usage range of the entire device;

[0019] (4) The present invention can position the stabilizing strip through the support plate, and at the same time, the stabilizing rod of the device can be telescopic, so as to drive the stabilizing buckle to move up and down, so that the stabilizing plate is in close contact with the bottom surface of the coal mine roadway, thus ensuring the stability of the entire device. At the same time, through the expansion and contraction of the adjusting rod, the adjusting block can be driven to rise and fall, thereby driving the adjusting block to move along the adjusting rail, so that the positioning frame rotates, thus changing the included angle between the side idler and the support, thus improving the usage range of the entire device;

[0020] (5) By telescoping the movable rod, the telescopic rod can be driven to move, so that the lock block can be inserted into the lock rod to lock the lock rod, thereby positioning the telescopic buckle, locking the main telescopic frame, locking the outer telescopic frame and the inner telescopic frame, so as to achieve the purpose of locking the ordinary column and the lifting column, ensuring the stability of the ordinary column and the lifting column. At the same time, by telescoping the telescopic rod, the telescopic buckle can be driven to lift and lower, ensuring the lifting and lowering of the telescopic shaft, facilitating the rotation of the main telescopic frame, facilitating the telescoping of the outer telescopic frame and the inner telescopic frame, facilitating the change of the distance between the two positioning frames, and ensuring the accuracy of the movement of the entire device.

The angle sensor 507 is used to monitor the rotation angle of the rotating shaft of the reversing block 506, so as to ensure the accuracy of the angle between the side idler 502 and the bracket 5, and thus the angle between the side idler 502 and the bracket 5 can be adjusted according to the weight and shape of the coal. The top of each adjusting rod 504 is hinged to an adjusting block 505. The adjusting block 505 is made of alloy materials and is used to connect the adjusting rod 504 and the bracket 5. An adjusting rail 508 is provided at the bottom of each positioning frame 503. The adjusting rail 508 is used to position the adjusting block 505. Each adjusting block 505 is slidably connected to the adjusting rail 508 outside it;

[0047] Before using this device, the staff sequentially insert the adjusting rod 504 into the locking block 9. At this time, due to the action of the locking plate 901, the positioning strip 902, and the locking spring 903, the locking rod 904 is inserted into the adjusting rod 504, thereby ensuring the stability of the locking block 9 and the adjusting rod 504, thus ensuring the stability of the bracket 5. At the same time, it ensures that the bracket 5 is detachable, thereby increasing the usage range of the entire device. Further, the staff put the belt 105 on the tops of several main idlers 501. When the entire device moves, the tensioning device at the tail end of the conveyor adjusts the distance between the tail end and the vehicle frame 1 following the telescoping of the main telescopic frame 602, thereby ensuring that the belt 105 is always taut, thus ensuring the conveying effect. Further, when the entire device moves into place, the controller 101 controls the telescoping of the lifting rod 303 of the lifting column 3, thereby driving the lifting of the bracket 5 inside the lifting column 3, so that the main idler 501 inside the lifting column 3 can be lifted and lowered. At the same time, the controller 101 controls the telescoping of the adapter rod 203, thereby driving the lifting of the adapter plate 204, driving the lifting of the adjusting rod 504 inside the vehicle frame 1, so that the main idler 501 inside the vehicle frame 1 can be lifted and lowered, so that the main idlers 501 inside the lifting column 3 and the main idlers 501 inside the vehicle frame 1 are at the same height, so that the entire device can adapt to the pitted coal mine roadway. At the same time, due to the self-weight of the belt 105, the belt 105 can be in close contact with all the main idlers 501, thus ensuring the stability of the entire device. Further, the controller 101 controls the telescoping of several adjusting rods 504, thereby driving the lifting of the adjusting block 505, driving the adjusting block 505 to move along the adjusting rail 508, so that the positioning frame 503 rotates. At this time, due to the action of the angle sensor 507, the rotation angle of the positioning frame 503 can be monitored, so as to change the included angle between the side idler 502 and the bracket 5 according to the material size and material quality, thereby increasing the usage range of the entire device. Further, the controller 101 controls the telescoping of the anti-disengagement rod 701, thereby driving the lifting of the anti-disengagement frame 7, driving the lifting of the baffle 707, so as to position the belt 105, thereby preventing the belt 105 from warping, thus ensuring the safety of the belt 105. At the same time, due to the action of the anti-disengagement spring 704 and the anti-disengagement shaft 705, the anti-disengagement plate 703 can be lowered, so that the anti-disengagement plate 703 is in close contact with the positioning frame 503, thereby preventing the belt 105 from disengaging from the side idler 502, thus further ensuring the stability of the belt 105, thus ensuring the coal conveying effect.

[0048] Embodiment 4, on the basis of Embodiment 1, by Figure 15 、 Figures 17 - 18Given that at the left end, each of the lock rods 8 is slidably connected to the lower end of the positioning frame 603, and at the right end, each of the lock rods 8 is slidably connected to the upper end of the positioning frame 603. An expansion shaft 604 is fixed to the outer end of each main expansion frame 602. The expansion shaft 604 is made of alloy material and is used to position the expansion buckle 801. An expansion buckle 801 is hinged to the outer end of each expansion shaft 604. Each expansion buckle 801 is fixedly connected to the lock rod 8 at its vertical outer end. The expansion buckle 801 is made of alloy material and is used to position the lock rod 8. A lower moving track 807 is provided inside each expansion buckle 801, and the lower moving track 807 is used to position the lower moving block 810. A lower moving block 810 is slidably connected inside each lower moving track 807. The lower moving block 810 is made of alloy material and is used to position the expansion rod 804. Each lower moving block 810 is fixedly connected to the expansion rod 804 at its vertical outer side. An upper moving block 808 is fixed to the vertical outer end of each expansion rod 804. The upper moving block 808 is made of alloy material and is used to position the expansion rod 804, so as to facilitate movement along the upper moving track 806. An upper moving track 806 is slidably connected to the outside of each upper moving block 808. The upper moving track 806 is made of alloy material and is used to position the upper moving block 808. Each upper moving track 806 is fixedly connected to the positioning frame 603 outside it. A moving rod 805 is fixed to the longitudinal outer end of each expansion rod 804. The moving rod 805 is telescopic, so as to drive the expansion rod 804 to move, so that the lock block 809 can be inserted into the lock rod 8 to lock the lock rod 8, thereby preventing the main expansion frame 602 from expanding and contracting by itself, and thus ensuring the stability of the entire device. A telescopic plate 802 is fixed to the longitudinal outer end of each moving rod 805. The telescopic plate 802 is made of alloy material and is used to position the moving rod 805. Each telescopic plate 802 is fixedly connected to the positioning frame 603 at its vertical outer end. Two positioning plates 803 are also fixed inside each positioning frame 603. The positioning plates 803 are made of alloy material and are used to position the main expansion frame 602. Each positioning plate 803 is slidably connected to the main expansion frame 602 inside it;

[0049] After the frame 1 is fixed, the controller 101 controls the contraction of the moving rod 805, thereby driving the movement of the telescopic rod 804, so that the lock block 809 disengages from the lock rod 8. At this time, the controller 101 controls the extension of the telescopic rod 804, thereby driving the telescopic buckle 801 to move inward, so that the main telescopic frame 602 extends, so that the outer telescopic frame 6 and the inner telescopic frame 601 extend, thereby driving the lifting column 3 and the ordinary column 2 to move, so as to change the distance between the ordinary column 2 and the lifting column 3, so as to adapt to roadways of different sizes. After the first lifting column 3 moves into place, the controller 101 controls the extension of the moving rod 805, so that the telescopic rod 804 moves, so that the upper moving block 808 moves along the upper moving track 806, and at the same time the lower moving block 810 moves along the lower moving track 807, further making the lock block 809 close to the lock rod 8, so that the lock rod 8 is fixed, so that the telescopic buckle 801 is locked, so that the main telescopic frame 602 is locked, so that the first lifting column 3 is locked. Further, the controller 101 controls the second moving rod 805 and the second telescopic rod 804 to move the second lifting column 3, and so on, so that the entire device can adapt to coal mine roadways of different sizes.

[0050] The working process of the present invention is as follows: before using the device, the staff inserts the adjusting rod 504 into the locking block 9 in turn. At this time, due to the action of the locking plate 901, the positioning bar 902 and the locking spring 903, the locking rod 904 is inserted into the adjusting rod 504, thereby ensuring the stability of the locking block 9 and the adjusting rod 504, thereby ensuring the stability of the bracket 5, and at the same time ensuring that the bracket 5 is detachable, thereby improving the use range of the entire device. Further, the staff puts the belt 105 on the top of several main rollers 501. When the entire device moves, the tightening device at the tail end of the conveyor follows the telescopic adjustment of the main telescopic frame 602 to adjust the distance between the tail end of the machine and the frame 1, so as to ensure the stability of the bracket 5. In order to ensure that the belt 105 is always tight, thereby ensuring the conveying effect, the staff will hinge the connecting rod 106 with the ordinary column 2 and the frame 1, and further the controller 101 controls the hydraulic pump station 103 to work, thereby controlling the crawler gear 108 to work, thereby driving the crawler 109 to rotate, thereby driving the entire device to move, and when the entire device moves to the desired position, the controller 101 controls the frame 1 to be fixed. After the frame 1 is fixed, the controller 101 controls the moving rod 805 to retract, thereby driving the telescopic rod 804 to move, so that the locking block 809 is separated from the locking rod 8. At this time, the controller 101 controls the telescopic rod 804 to extend, thereby The telescopic buckle 801 is driven to move inward, so that the main telescopic frame 602 is extended, so that the outer telescopic frame 6 and the inner telescopic frame 601 are extended, so as to drive the lifting column 3 and the ordinary column 2 to move, so as to change the spacing between the ordinary column 2 and the lifting column 3, so as to adapt to lanes of different sizes. When the first lifting column 3 moves into place, the controller 101 controls the moving rod 805 to extend, so that the telescopic rod 804 moves, so that the upper moving block 808 moves along the upper moving rail 806, and at the same time, the lower moving block 810 moves along the lower moving rail 807, and further makes the locking block 809 close to the locking rod 8, so that The locking rod 8 is fixed, so that the telescopic buckle 801 is locked, so that the main telescopic frame 602 is locked, and the first lifting column 3 is locked. Further, the controller 101 controls the second moving rod 805 and the second telescopic rod 804 to move the second lifting column 3. By analogy, the entire device can be adapted to coal mine tunnels of different sizes. At this time, the controller 101 controls the first stabilizing rod 402 to extend, thereby driving the first stabilizing plate 403 to descend, so that the first stabilizing head 404 descends and is inserted into the tunnel. At this time, due to the action of the stabilizing buckle 405, the first stabilizing plate 403 can be close to the bottom of the tunnel, thereby ensuring the stability of the first lifting column 3.Furthermore, the controller 101 controls the telescopic movement of the second main telescopic frame 602, enabling the movement of the second lifting column 3, and so on until all the lifting columns 3 are fixed, thus ensuring the stability of the entire device. Further, the controller 101 controls the telescopic movement of the lifting rod 303 of the lifting column 3, thereby driving the lifting of the bracket 5 inside the lifting column 3, so that the main idler 501 inside the lifting column 3 can be lifted. At the same time, the controller 101 controls the telescopic movement of the adapter rod 203, thereby driving the lifting of the adapter plate 204, driving the lifting of the adjusting rod 504 inside the vehicle frame 1, so that the main idler 501 inside the vehicle frame 1 is lifted, making the heights of the main idlers 501 inside the lifting column 3 and the main idlers 501 inside the vehicle frame 1 consistent, enabling the entire device to adapt to the potholed coal mine roadway. At the same time, due to the self - gravity of the belt 105, the belt 105 can be in close contact with all the main idlers 501, thus ensuring the stability of the entire device. Further, the controller 101 controls the telescopic movement of several adjusting rods 504, thereby driving the lifting of the adjusting block 505, driving the adjusting block 505 to move along the adjusting rail 508, causing the positioning frame 503 to rotate. At this time, due to the function of the angle sensor 507, the rotation angle of the positioning frame 503 can be monitored, and the angle between the side idler 502 and the bracket 5 can be changed according to the material size and material quality, thus expanding the application range of the entire device. Further, the controller 101 controls the telescopic movement of the anti - detachment rod 701, thereby driving the lifting of the anti - detachment frame 7, driving the lifting of the baffle 707, positioning the belt 105, preventing the belt 105 from warping, and ensuring the safety of the belt 105. At the same time, due to the functions of the anti - detachment spring 704 and the anti - detachment shaft 705, the anti - detachment plate 703 can be lowered, making the anti - detachment plate 703 in close contact with the positioning frame 503, preventing the belt 105 from detaching from the side idler 502, further ensuring the stability of the belt 105, and ensuring the coal conveying effect.
