[0057] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0058] like Figures 1 to 10 As shown, the triangular coal cleaning device 100 for the underground coal mining face of an embodiment of the present invention includes a hanging beam 1, a first driving member 2, a truss 3, a rotating frame 4, a second driving member 5, a push plate 6 and a third driving member 7.

[0059] The suspension beam 1 is arranged along a first direction (eg Figure 1 The first driving member 2 is arranged on the hanging beam 1. The truss 3 is connected to the first driving member 2, and the first driving member 2 drives the truss 3 to move in the first direction. The rotating frame 4 is rotatably arranged on the truss 3 with the first rotating axis as the center, and the first rotating axis is along the second direction (for example Figure 1 The second direction is perpendicular to the first direction. The second driving member 5 is arranged on the truss 3, and the second driving member 5 is connected to the rotating frame 4 to drive the rotating frame 4 to rotate around the first rotation axis. The push plate 6 is rotatably arranged on the rotating frame 4 around the second rotation axis, and the second rotation axis is along the third direction (for example Figure 1 The third direction is perpendicular to the second direction. The third driving member 7 is arranged on the rotating frame 4, and the third driving member 7 is connected to the push plate 6 to drive the push plate 6 to rotate around the second rotation axis.

[0060] In the working environment of the underground coal mining face triangular coal cleaning device 100 of the embodiment of the present invention, the suspension beam 1 extends in the horizontal direction, and the axis of the first rotating shaft 51 extends in the horizontal direction. Figure 1 and Figure 2In the direction shown, the suspension beam 1 extends in the front-to-back direction, the first rotation axis extends in the left-right direction, and the second rotation axis extends in the up-down direction. When not in use, the push plate 6 is in a horizontal or tilted state, which can be adjusted according to the needs of on-site operations. When adjusting, the second driving member 5 is controlled to output power to drive the push plate 6 to rotate to a suitable angle.

[0061] When in use, the first driving member 2 drives the truss 3 to move on the hanging beam 1, thereby driving the rotating frame 4 and the push plate 6 to move. When the push plate 6 is moved to the position above the coal slag, the second driving member 5 drives the rotating frame 4 to rotate, thereby driving the push plate 6 to rotate in the vertical direction, that is, driving the push plate 6 to gradually rotate to a vertical state. In other words, the second rotation axis gradually becomes vertical. As the push plate 6 rotates to a vertical state, the lower end of the push plate 6 gradually descends and inserts into the coal slag. Then the third driving member 7 is turned on, driving the push plate 6 to rotate around the second rotation axis, that is, the push plate 6 rotates horizontally, so that the push plate 6 pushes the coal slag and pushes the coal slag into the scraper conveyor. Repeat the action of pushing the coal slag by the push plate 6. During this period, the position of the push plate 6 in the coal slag area is adjusted by controlling the first driving member 2, so that all the coal slag is pushed into the scraper conveyor to complete the cleaning of the coal slag.

[0062] The triangular coal cleaning device for the underground coal mining face of the embodiment of the present invention is arranged as a whole based on the suspension beam 1, and can move the push plate 6 through the first driving member 2. When the cleaning device 100 does not clean the coal slag, the push plate 6 can be separated from the coal slag area without occupying the working space, thereby avoiding affecting the normal progress of other coal mining processes; the state of the push plate 6 in the up and down directions can be adjusted by the second driving member 5, so that the push plate 6 can be rotated to a horizontal state when the coal slag is not cleaned, thereby not occupying the working space; when cleaning the coal slag, the push plate 6 can be rotated to a vertical state so as to be inserted into the coal slag, and the push plate 6 can be driven by the third driving member 7 to push the coal slag to achieve the cleaning of the coal slag.

[0063] Therefore, the triangular coal cleaning device 100 of the underground coal mining face in the embodiment of the present invention can drive the push plate 6 to move laterally, rotate up and down, and rotate horizontally. It is flexible to operate, can improve the efficiency of cleaning coal slag, and occupies a small space, is easy to adjust, and has good applicability.

[0064] Specifically, the hanging beam 1 is a monorail hanging beam 1 .

[0065] In some embodiments, Figures 3 to 5 The first driving member 2 includes a moving frame 21 , a track wheel 22 , a transmission wheel 23 , a conveyor belt 24 and a first driving motor 25 .

[0066] The mobile frame 21 is sleeved on the suspension beam 1, and the mobile frame 21 is movable relative to the suspension beam 1, and the mobile frame 21 is connected to the truss 3. The track wheel 22 is rotatably arranged on the mobile frame 21, and the track wheel 22 abuts the mobile frame 21. The transmission wheel 23 is rotatably arranged on the mobile frame 21, and the conveyor belt 24 is sleeved on the transmission wheel 23 and the track wheel 22. The first drive motor 25 is arranged on the mobile frame 21, and the first drive motor 25 is connected to the transmission wheel 23. When the first drive motor 25 is turned on, the first drive motor 25 drives the transmission wheel 23 to rotate, thereby driving the conveyor belt 24 to rotate, and the conveyor belt 24 drives the track wheel 22 to rotate. The track wheel 22 relies on the friction between it and the suspension beam 1, so that when the track wheel 22 rotates, the track wheel 22 walks on the suspension beam 1, that is, the track wheel 22 drives the mobile frame 21 to move on the suspension beam 1, thereby driving the rotating frame 4 and the push plate 6 to move.

[0067] The first drive motor 25 and the track wheel 22 are driven by a conveyor belt 24 , which makes the transmission of motion more stable and reliable.

[0068] Specifically, the first driving motor 25 is a first servo motor.

[0069] In some embodiments, Figure 4 and Figure 5 As shown, the first driving member 2 further includes a sheave mechanism 26, which includes an active dial 261 and a driven sheave 262. The active dial 261 is connected to the output shaft of the first driving motor 25, and the driven sheave 262 is coaxially arranged with the transmission wheel 23. The driven sheave 262 is connected to the active dial 261. When the first driving motor 25 is turned on, the active dial 261 is driven to rotate, and the active dial 261 cooperates with the driven sheave 262 to make the driven sheave 262 rotate intermittently, thereby driving the transmission wheel 23 to rotate intermittently, and driving the track wheel 22 to rotate intermittently through the first conveyor belt 24, so that the moving frame 21 moves intermittently.

[0070] The grooved wheel mechanism 26 converts the continuous rotational motion output by the first drive motor 25 into intermittent rotational motion, and can divide a rotation cycle (i.e., one rotation) of the active dial 261 into six equal parts, so that the continuous intermittent rotation process of the transmission wheel 23 of rotation, stop, rotation, and stop prolongs the movement time of the moving frame 21, thereby providing sufficient working time for the coal pushing process of the push plate 6. In other words, the process of the third drive member 7 driving the push plate 6 to push the coal cinders and the process of the first drive member 2 driving the push plate 6 to move horizontally can be carried out simultaneously without affecting the coal pushing effect of the push plate 6. In this way, it is beneficial to improve the operating efficiency of the triangular coal cleaning device of the coal mining working face of the underground coal mine of the embodiment of the present invention.

[0071] In some embodiments, Figure 1 , Figure 2 and Figure 5 As shown, both ends of the truss 3 in the second direction are provided with mounting plates 31, and the mounting plates 31 extend downward. The second driving member 5 includes a first rotating shaft 51, a second driving motor 52, a first worm 53 and a first worm wheel 54. The first rotating shaft 51 is rotatably arranged on the mounting plate 31, the first rotating shaft 51 is fixedly connected to the rotating frame 4, and the first rotation axis is located on the axis of the first rotating shaft 51. The second driving motor 52 is arranged on one of the mounting plates 31, the first worm 53 is coaxially connected with the output shaft of the second driving motor 52, the first worm wheel 54 is arranged on the first rotating shaft 51, and the first worm wheel 54 is meshed with the first worm 53. When the second driving motor 52 is turned on, the output shaft of the second driving motor 52 drives the first worm 53 to rotate synchronously, and the first worm 53 is meshed with the first worm 53 for transmission, thereby driving the first rotating shaft 51 to rotate, driving the rotating frame 4 to rotate around the first rotation axis, thereby driving the push plate 6 to rotate in the up and down directions.

[0072] Specifically, the second drive motor 52 is a second servo motor.

[0073] The second drive motor 52 and the first rotating shaft 51 are driven by the first worm 53 and the first worm wheel 54. The first worm 53 and the first worm wheel 54 occupy a small space and are convenient for being arranged on the mounting plate 31. The meshing transmission process of the first worm 53 and the first worm wheel 54 is smooth and has little impact. At the same time, the rotating frame 4, the third drive member 7 and the push plate 6 have a certain weight, forming a load on the first worm wheel 54, so that the first worm wheel 54 cannot drive the first worm 53 to rotate, forming a self-locking function, which can avoid the rotation of the push plate 6 and the rotating frame 4 when the second drive motor 52 is turned off, thereby ensuring the self-locking effect and safety of the second drive member 5, thereby ensuring the reliability of the triangular coal cleaning device for the coal mining working face in the underground coal mine according to the embodiment of the present invention.

[0074] In some embodiments, the third driving member 7 includes a second rotating shaft 71, a third driving motor 72, a second worm 73 and a second worm wheel 74. The second rotating shaft 71 is rotatably mounted on one end (right end) of the rotating frame 4 along the third direction. The second rotating shaft 71 is fixedly connected to the push plate 6, and the second rotation axis is located on the axis of the second rotating shaft 71. The third driving motor 72 is arranged on the rotating frame 4, the second worm 73 is coaxially connected to the output shaft of the third driving motor 72, the second worm wheel 74 is arranged on the second rotating shaft 71, and the second worm wheel 74 is meshed with the second worm 73. When the third driving motor 72 is turned on, the output shaft of the third driving motor 72 drives the second worm 73 to rotate synchronously, and the second worm 73 is meshed with the second worm 73 for transmission, thereby driving the second rotating shaft 71 to rotate, driving the push plate 6 to rotate, and thus pushing the coal slag.

[0075] Specifically, the third drive motor 72 is a third servo motor.

[0076] The third drive motor 72 and the second rotating shaft 71 are driven by the second worm 73 and the second worm wheel 74. The second worm 73 and the second worm wheel 74 occupy a small space, which is convenient for arrangement on the push plate 6. The meshing transmission process is smooth and the impact is small. At the same time, it has a self-locking function, which can prevent the push plate 6 from rotating when the third drive motor 72 is turned off, thereby ensuring the self-locking effect and safety of the third drive member 7, thereby further ensuring the reliability of the triangular coal cleaning device for the underground coal mining face in the embodiment of the present invention.

[0077] In some embodiments, the push plate 6 has a first end and a second end opposite to each other in the third direction. Figure 6 As shown, the first end is the upper end of the push plate 6, and the second end is the lower end of the push plate 6. The third driving member 7 is arranged at the upper end of the push plate 6.

[0078] The push plate 6 is provided with a guide rail 66 at the first end, and a slide groove is provided on the guide rail 66. The slide groove extends along the width direction of the push plate 6. Figure 6 Left and right directions shown.

[0079] In some embodiments, Figures 6 to 10 As shown, the triangular coal cleaning device for the coal mining face of an underground coal mine of the present invention further includes a vibration assembly 8. The vibration assembly 8 includes a connecting rod 81, a slider 82, an elastic toggle member 83 and a toggle plate 84. One end of the connecting rod 81 is rotatably connected to the other end (left end) of the rotating frame 4, and the slider 82 is rotatably connected to the other end of the connecting rod 81, and the slider 82 is slidably arranged in the slide groove. The elastic toggle member 83 is arranged on the slider 82, and the elastic toggle member 83 is located outside the slide groove. The toggle plate 84 is arranged at the first end of the push plate 6, and the elastic toggle member 83 is opposite to the convex rack in the thickness direction of the push plate 6, and the elastic toggle member 83 abuts against the convex rack.

[0080] like Fig.10 As shown, the angle between the push plate 6 and the rotating frame 4 is α. When the third driving motor 72 drives the push plate 6 to rotate, α will change accordingly. Taking the process where α gradually increases from 0° as an example, since the two ends of the connecting rod 81 are respectively rotated to connect the rotating frame 4 and the slider 82, the slider 82 is slidably arranged on the push plate 6. During the rotation of the push plate 6, the slider 82 slides relative to the push plate 6, that is, the slider 82 slides in the slide groove. During the sliding process of the slider 82, the elastic toggle member 83 on the slider 82 moves with the slider 82 relative to the toggle plate 84, that is, the elastic toggle member 83 moves along the length direction of the convex rack. Figure 8 and Fig. 9As shown, since the elastic toggle member 83 has a certain elasticity and can be deformed, and the elastic toggle member 83 abuts against the convex tooth bar, during the movement of the elastic toggle member 83 along the length direction of the convex tooth bar, the elastic toggle member 83 gradually abuts against the tooth valley, tooth peak and tooth valley of the convex tooth, so that the elastic toggle member 83 is compressed and deformed to accumulate elastic force and then releases the elastic force to restore the deformation. When the elastic toggle member 83 releases the elastic force to restore the deformation, it impacts the toggle plate 84, thereby impacting the push plate 6, so that the push plate 6 vibrates. As the push plate 6 gradually rotates, the elastic toggle member 83 continues to impact the push plate 6 intermittently, and the push plate 6 vibrates intermittently, so that the coal slag attached to the push plate 6 falls off, ensuring the cleanliness of the push plate 6, thereby ensuring the effect of the push plate 6 in cleaning the coal slag.

[0081] In some embodiments, a through hole is provided on the slider 82. The elastic toggle member 83 includes a toggle pin 831, an elastic member 832 and a limit plate 833. The toggle pin 831 is movably provided in the through hole of the slider 82. Two limit plates 833 are provided on the toggle pin 831. One of the two limit plates 833 is adjacent to or abuts against the slider 82. One end of the elastic member 832 is connected to the slider 82. The other end of the elastic member 832 abuts against the other of the two limit plates 833. The toggle pin 831 abuts against the toggle plate 84. When the toggle pin 831 abuts against the tooth valley of the convex tooth, the one of the two limit plates 833 abuts against the slider 82. When the toggle pin 831 abuts against the tooth peak of the convex tooth, the elastic member 832 is deformed to the maximum, and the one of the two limit plates 833 is spaced apart from the slider 82. When the elastic toggle member 83 moves along the length direction of the convex rack, the toggle pin 831 reciprocates along the thickness direction of the push plate 6, and the elastic member 832 is compressed and reset reciprocatingly, thereby forming continuous intermittent vibration on the push plate 6.

[0082] In some embodiments, the elastic member 832 is a spring, and the spring is sleeved on the toggle pin 831. The spring has a simple structure and is easy to install. The spring is sleeved on the toggle pin 831, which can guide the deformation of the spring, avoid the skewness of the spring, and ensure the smoothness of the compression and extension of the spring, thereby ensuring the vibration effect of the elastic toggle member 83 on the push plate 6, ensuring the cleanliness of the push plate 6, and improving the reliability of the triangular coal cleaning device for the coal mining working face of the underground coal mine in the embodiment of the present invention.

[0083] In some embodiments, Figure 6As shown, the push plate 6 includes a first plate body 61, a second plate body 62 and a telescopic rod 63. One end (upper end) of the first plate body 61 in the third direction forms the first end of the push plate 6, and the first plate body 61 is provided with a mounting cavity, and the guide rail 66 is located at the upper end of the mounting cavity. One end (lower end) of the second plate body 62 in the third direction forms the second end of the push plate 6, and the second plate body 62 is slidably arranged in the mounting cavity. The telescopic rod 63 is located in the mounting cavity, one end of the telescopic rod 63 is arranged on the first plate body 61, and the other end of the telescopic rod 63 is connected to the other end of the second plate body 62 in the third direction. When the telescopic rod 63 is extended, it drives the second plate body 62 to gradually extend out of the mounting cavity, so that the size of the push plate 6 in the length direction gradually increases. When the telescopic rod 63 is shortened, it drives the second plate body 62 to gradually move into the mounting cavity, so that the size of the push plate 6 in the length direction gradually decreases.

[0084] Therefore, the length of the push plate 6 can be adjusted, so that the depth to which the push plate 6 can be inserted into the coal slag can be adjusted, so that the push plate 6 can adapt to coal slag of different depths, thereby improving the effect and efficiency of the push plate 6 in cleaning the coal slag, and improving the reliability of the triangular coal cleaning device of the underground coal mining working face in the embodiment of the present invention.

[0085] In some embodiments, the push plate 6 further includes a guide column 64 and a guide plate 65, the guide plate 65 is disposed in the installation cavity, a guide hole is disposed on the guide plate 65, the guide column 64 is connected to the other end of the second plate body 62, and the guide column 64 is slidably disposed in the guide hole.
