Description

Technical Field

[0002] The conveying system is an essential component of underground coal production operations. Its rational layout directly impacts the speed of coal mining, mine operating costs, and the workload and working environment of underground workers. Currently, fully mechanized mining teams in coal mines cut coal up to 20 times and advance more than 16 meters per day. With the development of high-end coal mining equipment and the demands of coal mining, the advance speed of fully mechanized mining faces will further increase. This increased advance speed renders the original method of manually dismantling a portion of the conveyor belt at a time insufficient, requiring multiple dismantlings by production shifts. This severely impacts production progress and mining efficiency, increases operating costs and the workload of underground workers, and poses serious safety hazards.

[0003] However, existing conveyor belt frames are only suitable for coal mine roadways of fixed dimensions, which limits the scope of application of the entire device. At the same time, existing belt frames can cause the belt to detach from the idlers inside the support due to belt friction when conveying materials, resulting in poor stability of the entire device.

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

[0016] (1) This invention can drive the outer telescopic frame and the inner telescopic frame to extend and retract by rotating the main telescopic frame, thereby changing the distance between the two positioning frames, thereby changing the distance between the ordinary column and the lifting column, thus adapting to coal mine roadways of different sizes, thereby improving the application range of the entire device. At the same time, this device can drive the support inside the lifting column to rise and fall by extending and retracting the lifting rod, thereby making the support height in the roadway the same, thus keeping the belt horizontal, thereby ensuring the coal conveying effect. At the same time, due to the function of the ordinary column, some supports do not need to be controlled, thereby saving resources. This device can quickly, efficiently and stably complete the extension and retraction of the whole machine, realizing the long-distance overlap between the belt conveyor and the self-moving tail after the belt frame of the fully mechanized mining face is removed. At the same time, this invention eliminates the influence of uneven roadway floor on the machine body through the unique design of the telescopic body column and telescopic frame, improving the speed and stability of the extension and retraction process. This invention completely solves the problem of discontinuous production in production shifts, ensures production continuity, improves production progress and mining efficiency, reduces operating costs and labor intensity of workers, improves production safety, and is widely applicable to various fully mechanized mining shafts.

[0017] (2) The present invention can drive the anti-detachment frame to move up and down by extending and retracting the anti-detachment rod, thereby driving the baffle to rise and fall, thereby positioning the height of the belt, preventing the belt from tilting, and ensuring the safety of the belt. The device can make the anti-detachment plate and the positioning frame closely fit by the anti-detachment strip and the anti-detachment spring, thereby preventing the belt from deviating and ensuring the stability of the entire device when conveying coal.

[0018] (3) The present invention can ensure the stability of the adjusting rod by locking the rod into the inside. At the same time, the device can make the locking plate close to the positioning bar by locking spring and positioning bar, so that the locking rod has a force close to the adjusting rod, thus ensuring the stability of the adjusting rod and facilitating disassembly. In addition, the device can drive the adapter plate to move up and down by extending and retracting the adapter rod, thereby driving the bracket inside the frame to rise and fall. This allows the frame to control the internal height of the frame according to the height of the conveyor, thereby improving the application range of the entire device.

[0019] (4) The present invention can position the stabilizing bar through the support plate, and the stabilizing rod of the device can be extended and retracted, thereby driving 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, thereby ensuring the stability of the entire device. At the same time, the device can drive the adjusting block to rise and fall through the extension and retraction of the adjusting rod, thereby driving the adjusting block to move along the adjusting rail, thereby causing the positioning frame to rotate, thereby changing the angle between the side roller and the support, thereby improving the application range of the entire device.

[0020] (5) This invention uses a telescopic rod to move, which in turn moves the telescopic rod, allowing the locking block to engage with the locking rod and lock it. This locks the telescopic buckle, which in turn locks the main telescopic frame, the outer telescopic frame, and the inner telescopic frame, thus achieving the purpose of locking the ordinary column and the lifting column. This ensures the stability of the ordinary column and the lifting column. At the same time, the telescopic rod can move the telescopic buckle up and down, which in turn ensures the telescopic shaft can move up and down. This facilitates the rotation of the main telescopic frame, the extension and retraction of the outer and inner telescopic frames, and the adjustment of the distance between the two positioning frames, thus ensuring the accuracy of the movement of the entire device.

A power supply 102 is fixed to the left end of the controller 101, providing the necessary electrical energy to the entire device. A hydraulic pump station 103 is also fixed to the top of the frame 1, which supplies fluid to the hydraulic motor, thereby providing power to the track gear 108 and driving the entire device to move. A cable reel 104 is also fixed to the left end of the hydraulic pump station 103 for convenient cable storage. Two track discs 107 are fixed to the bottom of the frame 1, which support the tracks 109. Each track disc 107 is rotatably connected to the right end of a track gear 108. The gear 108 drives the external track 109 to rotate. Each track gear 108 meshes with the external track 109. Two connecting buckles 205, made of alloy material, are fixed inside the frame 1. These buckles 205 are used to position the adapter rod 203. Each connecting buckle 205 has an adapter rod 203 hinged to its bottom. The adapter rod 203 is telescopic, allowing the adapter plate 204 to move up and down. Each adapter rod 203 has an adapter plate 204 fixed to its bottom, also made of alloy material. The adapter plate 204 is used to position the adjusting rod 504 inside the frame 1. Each adapter plate 204 is connected to the external adjusting rod 504. 04. Fixed connection: The lower ends of the front and rear adjusting rods 504 are rotatably connected to bottom rollers 509, which are used to position the belt 105. A connecting rod 106 is hinged to the left end of the frame 1. The connecting rod 106 is made of alloy material and is used to connect the frame 1 and the rightmost ordinary column 2. Each connecting rod 106 is hinged to the ordinary column 2 at its left end. Each ordinary column 2 has an ordinary column support tube 201 fixed at its bottom.

Each lifting column moving wheel 302 has a fixed lifting rod 303 inside, which is telescopic, allowing the internal adjusting rod 504 to move up and down, thereby raising and lowering the internal support bracket 5.This ensures that the height of the adjusting rods 504 inside the lifting columns 3 remains consistent, thereby guaranteeing the horizontal level of the belt 105 and the stability of the entire coal conveying system. The telescopic end of each lifting rod 303 is tightly fitted with its internal adjusting rod 504. Each lifting column 3 has a stabilizing bar 401 fixed on both its inner and outer sides.

The stabilizing heads 404 have a conical structure and, by inserting themselves into the coal mine roadway, ensure the stability of the entire device.

[0045] When using this device, the operator hinges the connecting rod 106 to the ordinary column 2 and the frame 1. The controller 101 then controls the hydraulic pump station 103 to operate, which in turn controls the track gear 108, causing the track 109 to rotate. This moves the entire device. When the device reaches the desired position, the controller 101 fixes the frame 1. At this time, the controller 101 controls the first lifting column 3 to move, causing the inner telescopic frame 601 and the main telescopic frame 602 to extend and retract, thus causing the first set of ordinary column moving wheels 202 to rotate. The first set of ordinary columns 2 are moved to the required position. At this time, the controller 101 controls the first stabilizing rod 402 to extend, thereby driving the first stabilizing plate 403 to descend. As a result, the first stabilizing head 404 descends and inserts into the tunnel. At this time, due to the action of the stabilizing buckle 405, the first stabilizing plate 403 can be tightly attached to the bottom of the tunnel, thereby ensuring the stability of the first lifting column 3. Furthermore, the controller 101 controls the extension and retraction of the second main telescopic frame 602, which can move the second lifting column 3. This process continues until all the lifting columns 3 are fixed, thereby ensuring the stability of the entire device.

An angle sensor 507 is fixed to the left end of the rotating shaft of the positioning frame 503. The angle sensor 507 is used to monitor the rotation angle of the rotating shaft of the reversing block 506, thereby ensuring the accuracy of the angle between the side roller 502 and the support 5. The angle between the side roller 502 and the support 5 can be adjusted according to the weight and shape of the coal. An adjustment block 505 is hinged to the top of each adjusting rod 504. The adjustment block 505 is made of alloy material and is used to connect the adjusting rod 504 and the support 5. An adjustment rail 508 is provided at the bottom of each positioning frame 503. The adjustment rail 508 is used to position the adjustment block 505. Each adjustment block 505 is slidably connected to the adjustment rail 508 outside it.

[0047] Before using this device, the operator inserts 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, thus ensuring the stability of the locking block 9 and the adjusting rod 504, thereby ensuring the stability of the bracket 5 and ensuring that the bracket 5 is detachable, thus increasing the overall usability of the device. Further, the operator places the belt 105 on top of several main idler rollers 501. When the entire device moves, the tensioning device at the tail end of the conveyor follows the extension and retraction of the main telescopic frame 602 to adjust the tail end of the conveyor relative to the frame 1. The spacing is adjusted to ensure that the belt 105 remains taut at all times, thus ensuring the conveying effect. Furthermore, once the entire device is in place, the controller 101 controls the extension and retraction of the lifting rod 303 of the lifting column 3, thereby raising and lowering the bracket 5 inside the lifting column 3. This allows the main idler roller 501 inside the lifting column 3 to rise and fall. Simultaneously, the controller 101 controls the extension and retraction of the adapter rod 203, thereby raising and lowering the adapter plate 204. This, in turn, raises and lowers the adjusting rod 504 inside the frame 1, thereby raising and lowering the main idler roller 501 inside the frame 1. This ensures that the main idler roller 501 inside the lifting column 3 and the frame... The height of the main idler rollers 501 inside is kept consistent, making the entire device adaptable to uneven coal mine roadways. Simultaneously, due to the weight of the belt 105, it remains in close contact with all the main idler rollers 501, ensuring the stability of the entire device. Furthermore, the controller 101 controls the extension and retraction of several adjusting rods 504, thereby raising and lowering the adjusting block 505, which in turn moves the adjusting block 505 along the adjusting rail 508, causing the positioning frame 503 to rotate. At this time, the angle sensor 507 monitors the rotation angle of the positioning frame 503, thereby adjusting the side idler rollers 501 according to the material size and quality. The angle between 02 and the bracket 5 increases the overall usability of the device. Furthermore, the controller 101 controls the extension and retraction of the anti-detachment rod 701, thereby driving the anti-detachment frame 7 to rise and fall, which in turn drives the baffle 707 to rise and fall, thus positioning the belt 105 and preventing the belt 105 from tilting up, thereby ensuring the safety of the belt 105. At the same time, due to the action of the anti-detachment spring 704 and the anti-detachment shaft 705, the anti-detachment plate 703 can be lowered, thereby making the anti-detachment plate 703 close to the positioning frame 503, thereby preventing the belt 105 from detaching from the side idler roller 502, thereby further ensuring the stability of the belt 105 and ensuring the coal conveying effect.

[0048] Example 4, based on Example 1, is... Figure 15 , Figures 17-18Given that each locking rod 8 on the left end is slidably connected to the lower end of the positioning frame 603, and each locking rod 8 on the right end is slidably connected to the upper end of the positioning frame 603, each main telescopic frame 602 has a telescopic shaft 604 fixed to its outer end. The telescopic shaft 604 is made of alloy material and is used to position the telescopic buckle 801. Each telescopic shaft 604 has a telescopic buckle 801 hinged to its outer end. Each telescopic buckle 801 is fixedly connected to the locking rod 8 at its vertical outer end. The telescopic buckle 801 is made of alloy material and is used to position the locking rod 8. The snap fastener 801 has a lower moving rail 807 inside, which is used to position the lower moving block 810. Each lower moving rail 807 has a lower moving block 810 slidably connected inside it. The lower moving block 810 is made of alloy material and is used to position the telescopic rod 804. Each lower moving block 810 is fixedly connected to the telescopic rod 804 on its vertical outer side. Each telescopic rod 804 has an upper moving block 808 fixed to its vertical outer end. The upper moving block 808 is made of alloy material and is used to position the telescopic rod 804, thereby... For easy movement along the upper moving rail 806, each upper moving block 808 is slidably connected to the upper moving rail 806 on its outside. The upper moving rail 806 is made of alloy material and is used to position the upper moving block 808. Each upper moving rail 806 is fixedly connected to its external positioning frame 603. Each telescopic rod 804 has a moving rod 805 fixed to its longitudinal outer end. The moving rod 805 is telescopic, which can drive the telescopic rod 804 to move, thereby allowing the locking block 809 to engage with the locking rod 8, thereby locking the locking rod 8 and preventing the main telescopic frame from moving. 602 self-extension ensures the stability of the entire device. Each of the moving rods 805 has a telescopic plate 802 fixed to its longitudinal outer end. 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. Each positioning frame 603 also has two positioning plates 803 fixed inside. The positioning plates 803 are made of alloy material and are used to position the main telescopic frame 602. Each positioning plate 803 is slidably connected to the main telescopic frame 602 inside it.

[0049] After the frame 1 is fixed, the controller 101 controls the moving rod 805 to retract, thereby driving the telescopic rod 804 to move, causing the locking block 809 to disengage from the locking rod 8. At this time, the controller 101 controls the telescopic rod 804 to extend, thereby driving the telescopic buckle 801 to move inward, thereby causing the main telescopic frame 602 to extend, thereby causing the outer telescopic frame 6 and the inner telescopic frame 601 to extend, thereby driving the lifting column 3 and the ordinary column 2 to move, thereby changing the distance between the ordinary column 2 and the lifting column 3, thus adapting to different sizes of tunnels. When the first lifting column 3 moves into place, the controller 101 controls the... The extension of the moving rod 805 causes the telescopic rod 804 to move, which in turn causes the upper moving block 808 to move along the upper moving rail 806, while the lower moving block 810 moves along the lower moving rail 807. This further causes the locking block 809 to press tightly against the locking rod 8, thereby fixing the locking rod 8, locking the telescopic buckle 801, locking the main telescopic frame 602, and locking the first lifting column 3. The controller 101 then controls the second moving rod 805 and the second telescopic rod 804 to move the second lifting column 3, and so on. This allows the entire device to be adapted to coal mine roadways of different sizes.

[0050] The workflow of this invention is as follows: Before using this device, the operator inserts the adjusting rod 504 into the locking block 9 in sequence. 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, and ensuring that the bracket 5 is detachable, thereby improving the usability of the entire device. Further, the operator places the belt 105 on top of several main idler rollers 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 frame 1 following the extension and retraction of the main telescopic frame 602. To ensure the conveying effect, the belt 105 is always taut. At this point, the operator hinges the connecting rod 106 to the ordinary column 2 and the frame 1. The controller 101 then controls the hydraulic pump station 103 to operate, which in turn controls the track gear 108, causing the track 109 to rotate and thus moving the entire device. When the device reaches the desired position, the controller 101 fixes the frame 1. Once the frame 1 is fixed, the controller 101 controls the moving rod 805 to retract, thereby moving the telescopic rod 804. This causes the locking block 809 to disengage from the locking rod 8. At this point, the controller 101 controls the telescopic rod 804 to extend. The telescopic buckle 801 is moved inward, causing the main telescopic frame 602 to extend, which in turn causes the outer telescopic frame 6 and the inner telescopic frame 601 to extend. This, in turn, causes the lifting column 3 and the ordinary column 2 to move, thereby changing the distance between the ordinary column 2 and the lifting column 3 to adapt to different sized tunnels. When the first lifting column 3 moves into position, the controller 101 controls the moving rod 805 to extend, causing the telescopic rod 804 to move. This causes the upper moving block 808 to move along the upper moving rail 806, and simultaneously causes the lower moving block 810 to move along the lower moving rail 807. This further causes the locking block 809 to press tightly against the locking rod 8, thereby... The locking rod 8 is fixed, thereby locking the telescopic buckle 801, which in turn locks the main telescopic frame 602, and thus locks the first lifting column 3. 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. This allows the entire device to adapt to coal mine roadways of different sizes. At this time, the controller 101 controls the first stabilizing rod 402 to extend, thereby causing the first stabilizing plate 403 to descend, and the first stabilizing head 404 to descend and insert into the roadway. Due to the action of the stabilizing buckle 405, the first stabilizing plate 403 is kept close to the bottom of the roadway, thus ensuring the stability of the first lifting column 3.Furthermore, the controller 101 controls the extension and retraction of the second main telescopic frame 602, which allows the second lifting column 3 to move, and so on, until all the lifting columns 3 are fixed, thereby ensuring the stability of the entire device. The controller 101 further controls the extension and retraction of the lifting rod 303 of the lifting column 3, thereby driving the support 5 inside the lifting column 3 to rise and fall, thus allowing the main support roller 501 inside the lifting column 3 to rise and fall. Simultaneously, the controller 101 controls the extension and retraction of the adapter rod 203, thereby driving the... The adapter plate 204 is raised and lowered, thereby causing the adjusting rod 504 inside the frame 1 to rise and fall, which in turn causes the main idler roller 501 inside the frame 1 to rise and fall. This ensures that the main idler roller 501 inside the lifting column 3 and the main idler roller 501 inside the frame 1 are at the same height, making the entire device adaptable to uneven coal mine roadways. Simultaneously, due to the weight of the belt 105, it remains in close contact with all the main idler rollers 501, ensuring the stability of the entire device and further enhancing control. The controller 101 controls the extension and retraction of several adjusting rods 504, thereby driving the adjusting block 505 to rise and fall, which in turn moves the adjusting block 505 along the adjusting rail 508, causing the positioning frame 503 to rotate. At this time, the angle sensor 507 monitors the rotation angle of the positioning frame 503, thus changing the angle between the side roller 502 and the support 5 according to the material size and quality, thereby improving the overall usability of the device. Furthermore, the controller 101 controls the extension and retraction of the anti-detachment rod 701. This causes the anti-detachment frame 7 to rise and fall, which in turn causes the baffle 707 to rise and fall, thereby positioning the belt 105 and preventing it from tilting up, thus ensuring the safety of the belt 105. Simultaneously, the anti-detachment spring 704 and the anti-detachment shaft 705 cause the anti-detachment plate 703 to descend, ensuring it is tightly against the positioning frame 503, preventing the belt 105 from detaching from the side idler roller 502, further ensuring the stability of the belt 105 and thus guaranteeing the coal conveying effect.
