[0002] Coal, as my country's primary energy source, plays a vital role in the national economy. my country's resource type is characterized by abundant coal, scarce oil, and limited natural gas, which determines that our country will heavily rely on coal for energy consumption. Therefore, to ensure the clean and efficient utilization of coal, it must be sent to coal preparation plants for washing and processing after being mined underground.

[0003] Existing coal washing technologies are limited by manufacturing capabilities, and many problems remain with key coal washing equipment in coal preparation plants. Some plants' equipment still fails to meet industry standards. For example, the arc screen, a crucial dewatering and desliming device in coal preparation plants, relies entirely on manual operation for its rotation and turning. This results in low operating efficiency, high labor intensity for workers, and high production costs for existing dewatering and desliming equipment. This not only affects production efficiency but also hinders the development of automation in coal washing equipment. Summary of the Invention

[0044] Coal, as my country's primary energy source, plays a vital role in the national economy. my country's resource type is characterized by abundant coal, scarce oil, and limited gas, which determines that our country will heavily rely on coal for energy consumption. Therefore, to ensure the clean and efficient utilization of coal, it must be sent to coal preparation plants for washing and processing after being mined underground. Existing washing and processing technologies are limited by the level of manufacturing capabilities, and many problems still exist in key washing and processing equipment in coal preparation plants. Some coal preparation plants' washing and processing equipment still does not meet industry standards. For example, the arc screen 12, as an important dewatering and desliming device in coal preparation plants, relies entirely on manual operation for its rotation and turning. This results in low operating efficiency, high labor intensity for workers, and high production costs for existing dewatering and desliming equipment. This not only affects production efficiency but also hinders the development of automation in coal washing and processing equipment.

[0045] To solve the above problems, refer to Figure 1 This application provides a mining pure electric drive tilting device, comprising: a support frame 2 with a U-shaped cross-section; a tilting and turning connecting frame 5, wherein its left and right flanges are fixedly connected to the output ends of the left tilting drive mechanism 3 and the right tilting drive mechanism 4, respectively; a turning drive mechanism 7, wherein its housing 306 is fixedly connected to the upper flange of the tilting and turning connecting frame 5, and its output end is connected to a transition flange 9; a tilting position detection device 6, installed on the side wall of the tilting and turning connecting frame 5, for detecting the tilting angle; a turning position detection device 8, installed on the tilting and turning connecting frame 5, wherein its other end is connected to the transition flange 9, for detecting the turning angle; a safety mechanism 10, one end of which is connected to the support frame 2, and the other end of which is connected to the tilting and turning connecting frame 5; and a controller 11, electrically connected to the tilting position detection device 6, the turning position detection device 8, the left tilting drive mechanism 3, the right tilting drive mechanism 4, and the turning drive mechanism 7.

[0046] Specifically, the support frame 2 consists of a base plate and welded left / right support seats forming a U-shaped cross-section, which is used to support the overall structure; the left flange of the flip-back connecting frame 5 is fixed to the output flange 305 of the left flip drive mechanism 3, the right flange is fixed to the output end of the right flip drive mechanism 4, and the upper flange is fixed to the housing 306 of the rotary drive mechanism 7; the lower end of the transition flange 9 is connected to the output end of the rotary drive mechanism 7, and the upper end is fixed to the arc screen 12; the detection device includes two parts: a flip position detection device 6 and a rotary position detection device 8. The tilt position sensor 602 in the flip position detection device is installed on the flip-back connecting frame 5 through the first fixing frame 601, and the angle sensor 801 in the rotary position detection device 8 is fixed to the transition flange 9 through the second fixing frame 802; the safety mechanism 10 is connected to the base plate of the support frame 2 and the fixing lug 1001 of the flip-back connecting frame 5 by a hinge 1002; the controller 11 is used to receive sensor signals and control the motor 301. A feeding device 13 is provided at the other end of the arc-shaped screen 12 (since this is prior art, it will not be described in detail).

[0047] In this way, the rotation of the left-side flipping drive mechanism 3, the right-side flipping drive mechanism 4, and the slewing drive mechanism 7 drives the slewing connecting frame to rotate in the tumbling and yaw directions, thereby improving the automation of the washing and screening equipment.

[0048] like Figure 2 As shown, both the left-side tilting drive mechanism 3 and the right-side tilting drive mechanism 4 in this application include a motor 301, a reducer 302, an adapter flange 303, a worm gear 304, an output flange 305, a housing 306, and a worm wheel 307. The motor 301, reducer 302, worm gear 304, and worm wheel 307 are connected in sequence to form an L-shaped structure. The motor 301 is used to drive the worm wheel 307 to rotate through the worm gear 304.

[0049] Specifically, motor 301 outputs power to reducer 302. Adapter flange 303 connects worm gear 307 to reducer 302 in an L-shaped configuration. Worm 304 meshes with worm gear 307, transmitting torque to output flange 305. Housing 306 encapsulates the transmission components. Furthermore, the right-side tilting drive mechanism 4 and the left-side tilting drive mechanism 3 have symmetrical and identical structures, while the rotary drive mechanism 7 operates on a similar principle and has the same mechanism. Thus, the left-side tilting drive mechanism 3 and the right-side tilting drive mechanism 4 function as the driving mechanism for tilting. The left-side tilting drive mechanism 3 and the right-side tilting drive mechanism 4 are symmetrically arranged, and their output ends operate synchronously.

[0050] like Figure 4As shown, to improve the safety of this application, the safety mechanism 10 includes fixed lugs 1001 provided on the support frame 2 and the tilting connecting frame 5, and hinges 1002 connecting the fixed lugs 1001 on both sides. Specifically, one set of lugs is welded to the base plate of the support frame 2, and the other set is welded to the tilting connecting frame 5. The length of the hinge 1002 is set such that it is tightened when the tilt angle reaches 80°, limiting further rotation.

[0051] like Figure 5 , 6 As shown, the flip position detection device 6 includes a first fixing frame 601 and a tilt position sensor 602. The tilt position sensor 602 is fixed to the flip-back connecting frame 5 via the first fixing frame 601. The rotation position detection device 8 includes an angle sensor 801 and a second fixing frame 802. The angle sensor 801 is fixed to the side wall of the transition flange 9 via the second fixing frame 802.

[0052] like Figure 3 As shown, this application also includes a lifting device 1, which includes: a main support base 101 with a ball groove 105 inside; a lifting platform 102 slidably connected to the inside of the main support base 101, with a nut 103 at its top; a support frame 2 fixed to the lifting platform 102; and a lead screw 104 coaxially sleeved inside the nut 103 and rotatably connected to the nut 103; one end of the lead screw 104 is hinged to the ball groove 105, and the other end is provided with a rotating handle. Specifically, a support member with a ball groove 105 is welded inside the main support base 101, one end of the lead screw 104 is hinged to the ball groove 105, and the other end is rotatably engaged with the nut 103 of the lifting platform 102. The support frame 2 is fixed to the lifting platform 102, thereby achieving the function of height adjustment.

[0053] Meanwhile, in order to improve the sealing performance of this application, rubber sleeves are provided in the bolt connection holes of the left flange, right flange and upper flange of the flip-top connecting frame 5.

[0054] This application also provides a method for using a pure electric drive tilting device for mining:

[0055] Step 1 - Initialization: Controller 11 controls the rotary drive mechanism 7 to drive the tilting connecting frame 5 to rotate horizontally, so that the angle sensor 801 outputs a 0° signal. Then, the left / right tilting drive mechanism 4 drives the tilting connecting frame 5 to tilt and roll, so that the tilt position sensor 602 outputs a 0° signal.

[0056] Step 2 - Feeding: Turn on the timer 1101 of the controller 11 to start timing, turn on the feeding device 13, and turn off the feeding device 13 when the timing ends.

[0057] Step 3 - Flipping: The dual motors 301 on the left and right sides rotate synchronously in the forward direction, driving the flipping connecting frame 5 to tilt at an angle of 75°. At this time, the tilt position sensor 602 detects the 75° output signal, and the motors 301 automatically stop working.

[0058] Step 4 - Rotation: The motor 301 of the rotary drive mechanism 7 rotates forward, driving the transition flange 9 to rotate 180°. At this time, the angle sensor 801 detects the 180° output signal, and the motor 301 automatically stops working.

[0059] Step 5 - Reset Cycle: The dual motors 301 on both sides rotate synchronously in reverse. When the tilt position sensor 602 detects a 0° output signal, the motors 301 automatically stop working. Return to Step 2.

[0060] In addition, this application also provides a method for early warning, when the tilt position sensor 602 outputs a signal <-5° or >80°:

[0061] Hinge 1002 is taut to restrict the rotation of the flip-back connecting frame 5;

[0062] The controller 11 detects the overload current of the motor 301, immediately stops the motor and triggers an audible and visual alarm.

[0063] In another embodiment of this application, the worm gear 307 and worm 304 transmission can be replaced by a combination of planetary gears and a brake, and the lifting device 1 can be replaced by a hydraulic lifting mechanism.

[0064] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
