Abstract
Description
Technical Field
[0001] This utility model relates to the field of correction mechanism technology, and in particular to a correction linkage mechanism for coal mines. Background Technology
[0002] Straightening idler sets are a common and effective mechanical straightening mechanism. They typically detect the lateral force generated when the conveyor belt deviates from its designated position, drive a rotatable idler frame to deflect at a certain angle, and utilize the frictional force between the idler and the conveyor belt to guide the conveyor belt back to the center position.
[0003] The coal materials currently being transported are often highly moist and viscous, making them extremely prone to adhering to the surface of the tracking idlers. The adhering coal residue causes the surface of the tracking idlers to be uneven and the diameter to be inconsistent, thereby changing the contact state and friction characteristics between them and the conveyor belt. This not only significantly reduces the sensitivity and accuracy of the tracking effect, causing the tracking action to lag or fail, but the continuously accumulated coal residue also aggravates the wear and running resistance of the idlers, increases equipment energy consumption, and may scratch the lower surface of the conveyor belt, creating new safety hazards. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that the coal materials being transported are often highly moist and viscous, easily adhering to the surface of the guiding rollers. The adhering coal residue causes the guiding rollers to become uneven in surface and diameter, thereby altering their contact state and friction characteristics with the conveyor belt. This not only significantly reduces the sensitivity and accuracy of the guiding effect, but also provides a guiding linkage mechanism for coal mines.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a coal mine correction linkage mechanism, comprising a conveying device, a cleaning mechanism fixedly connected to the outer surface of the conveying device, an adjusting mechanism fixedly connected to the outer surface of the cleaning mechanism, a support frame fixedly connected to the conveying device, a correction frame slidably connected to the outer surface of the support frame, a correction roller fixedly connected to the outer surface of the correction frame, a fixing frame fixedly connected to the outer surface of the correction frame, a fixing rod sleeved on the inner wall of the fixing frame, and an adjusting mechanism comprising a knob, a lead screw fixedly connected to the outer surface of the knob, a limit block fixedly connected to one end of the lead screw, and a scraper sleeved on the outer surface of the limit block.
[0006] In a preferred embodiment, a sliding plate is fitted onto the inner wall of the fixing rod, and the sliding plate is slidably connected to the fixing rod.
[0007] In a preferred embodiment, a locking block is fixedly connected to the outer surface of the slide block, the locking block is slidably connected to the fixing rod, and a limiting rod is sleeved on the inner wall of the locking block, the limiting rod being fixedly connected to the fixing rod.
[0008] In a preferred embodiment, a spring is sleeved on the outer surface of the limiting rod, and the two ends of the spring are respectively fixedly connected to one side of the locking block and the inner wall of the fixing rod.
[0009] In a preferred embodiment, the outer surface of the fixing frame is provided with a locking hole that is adapted to the locking block, and the inner wall of the locking hole is engaged with the outer surface of the locking block.
[0010] In a preferred embodiment, the inner wall of the fixing rod is provided with a screw hole that matches the thread line on the outer surface of the lead screw.
[0011] In a preferred embodiment, the inner wall of the scraper is provided with a rotating hole that matches the limiting block, and the inner wall of the rotating hole is rotatably connected to the outer surface of the limiting block.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention ensures the normal operation of coal mine conveying through a conveying device, cleans coal slag adhering to the surface of the correction roller through a cleaning mechanism, provides an installation environment for other components through a support frame, and provides an installation environment for the correction roller through a correction frame. The correction roller corrects the conveyor belt. When coal slag needs to be cleaned from the correction roller, the fixing rod is locked in place by engaging with the fixing frame. Then, rotating the knob drives the lead screw to rotate inside the fixing rod. The rotation of the lead screw drives the limit block to rotate inside the scraper, ensuring that the scraper does not rotate while the lead screw moves. Then, the movement of the lead screw drives the scraper to move, so that the scraper comes into contact with the surface of the correction roller, thereby cleaning the coal slag on the surface of the correction roller.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1 like Figures 1-4 As shown, this utility model provides a technical solution: a coal mine correction linkage mechanism, including a conveying device 1, a cleaning mechanism 2 fixedly connected to the outer surface of the conveying device 1, an adjusting mechanism 3 fixedly connected to the outer surface of the cleaning mechanism 2, the cleaning mechanism 2 including a support frame 21, the support frame 21 fixedly connected to the conveying device 1, a correction frame 22 slidably connected to the outer surface of the support frame 21, a correction roller 23 fixedly connected to the outer surface of the correction frame 22, a fixing frame 24 fixedly connected to the outer surface of the correction frame 22, a fixing rod 25 sleeved on the inner wall of the fixing frame 24, the adjusting mechanism 3 including a knob 31, a lead screw 32 fixedly connected to the outer surface of the knob 31, a screw hole adapted to the thread line on the outer surface of the fixing rod 25 on the inner wall, a limit block 33 fixedly connected to one end of the lead screw 32, a scraper 26 sleeved on the outer surface of the limit block 33, a rotating hole adapted to the limit block 33 on the inner wall of the scraper 26, and the inner wall of the rotating hole rotatably connected to the outer surface of the limit block 33.
[0021] In this embodiment, the conveying device 1 ensures the normal operation of coal mine conveying, the cleaning mechanism 2 cleans the coal slag adhering to the surface of the correction roller 23, the support frame 21 provides an installation environment for other components, the correction frame 22 provides an installation environment for the correction roller 23, and the correction roller 23 corrects the conveyor belt. When coal slag needs to be cleaned from the correction roller 23, the fixing rod 25 is fixed by engaging with the fixing frame 24. Then, the knob 31 is rotated to drive the lead screw 32 to rotate inside the fixing rod 25. The rotation of the lead screw 32 drives the limit block 33 to rotate inside the scraper 26, ensuring that the scraper 26 does not rotate while the lead screw 32 moves. Then, the movement of the lead screw 32 drives the scraper 26 to move, so that the scraper 26 is in contact with the surface of the correction roller 23, thereby cleaning the coal slag on the surface of the correction roller 23.
[0022] Example 2 like Figures 1-5 As shown, a sliding plate 27 is sleeved on the inner wall of the fixing rod 25, and the sliding plate 27 is slidably connected to the fixing rod 25. A locking block 28 is fixedly connected to the outer surface of the sliding plate 27, and the locking block 28 is slidably connected to the fixing rod 25. A limiting rod 29 is sleeved on the inner wall of the locking block 28, and the limiting rod 29 is fixedly connected to the fixing rod 25. A spring 210 is sleeved on the outer surface of the limiting rod 29, and the two ends of the spring 210 are respectively fixedly connected to one side of the locking block 28 and the inner wall of the fixing rod 25. A locking hole adapted to the locking block 28 is opened on the outer surface of the fixing frame 24, and the inner wall of the locking hole is engaged with the outer surface of the locking block 28.
[0023] In this embodiment, when the fixing rod 25 is engaged with the fixing frame 24, the pressing slide plate 27 drives the locking block 28 to move along the limiting rod 29 into the fixing rod 25. The movement of the locking block 28 compresses the spring 210, putting the spring 210 into a compressed state. Then, the locking block 28 is housed inside the fixing rod 25. Then, the fixing rod 25 is engaged with the fixing frame 24. The rebound of the spring 210 drives the locking block 28 to reset, so that the locking block 28 engages with the locking hole, completing the fixing of the fixing rod 25 and ensuring that the fixing rod 25 will not fall off.
[0024] Working principle: like Figures 1-5As shown, in this utility model, when it is necessary to clean the slag on the surface of the straightening roller 23, the operator first presses the sliding plate 27. At this time, the sliding plate 27 drives the locking block 28 to move along the limiting rod 29 into the fixing rod 25. During the movement of the locking block 28, the spring 210 is compressed, and the locking block 28 is housed inside the fixing rod 25. Then, the fixing rod 25 is inserted into the fixing frame 24. After that, the sliding plate 27 is released, and the spring 210 rebounds, causing the locking block 28 to reset. The locking block 28 engages with the locking hole, completing the fixing of the fixing rod 25 and the fixing frame 24.
[0025] The operator then rotates knob 31, which drives the lead screw 32 to rotate inside the fixed rod 25. Since the inner wall of the fixed rod 25 has a threaded hole that matches the threaded lines on the outer surface of the lead screw 32, the lead screw 32 moves along the threaded hole as it rotates. The limiting block 33 at one end of the lead screw 32 rotates inside the scraper 26. Because the inner wall of the scraper 26 has a rotating hole that matches the limiting block 33, the scraper 26 will not rotate while the lead screw 32 moves. The movement of the lead screw 32 drives the scraper 26 to move, causing the scraper 26 to come into contact with the surface of the straightening roller 23. As the straightening roller 23 rotates, the scraper 26 can clean off the coal slag adhering to the surface of the straightening roller 23, preventing coal slag accumulation from affecting the straightening effect of the straightening roller 23 on the conveyor belt.
[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
