[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] See also Figure 1-Figure 2 As shown, in an embodiment of the utility model, an all-in-one machine for driving a scraper conveyor is proposed, specifically including an electric motor 1, wherein the electric motor 1 has a power output end, and the first output shaft 2 of the electric motor 1 is located at the power output end. Specifically, the first output shaft 2 can extend from the power output end, or be located at the power output end in a concave structure. Specifically, it can be adaptively manufactured to match the second output shaft connected to the reducer 4, without limiting the specific structural shape, and mainly realizes power output; at the same time, a plurality of first mounting holes 3 located at the power output end and uniformly distributed along the circumferential direction are provided on the electric motor 1, and the reducer 4 is sleeved on the electric motor 1, and the reducer 4 is provided with a second mounting hole 5 aligned with the first mounting hole 3, and the fastener locks the first mounting hole 3 and the second mounting hole 5, and the reducer 4 is sleeved and positioned by the electric motor 1. The fastener locks the first mounting hole 3 and the second mounting hole 5 to realize the fixation of the reducer 4 on the electric motor 1, so that the second output shaft of the reducer 4 is spline-connected to the first output shaft 2, so as to realize internal connection and reduce the volume. At the same time, a scraper flange 6 is installed on the reducer 4. The scraper flange 6 is used to connect to the scraper conveyor. The scraper flange 6 is used to install the entire structure on the scraper conveyor, making it easy to disassemble and assemble the entire structure. At the same time, a high-voltage inverter 7 and a power supply unit 8 are installed on the motor 1. The high-voltage inverter 7 is located on the top of the motor 1, and the power supply unit 8 is connected to the side of the high-voltage inverter 7. The high-voltage inverter 7 and the power supply unit 8 are also synchronously integrated into the motor 1, further improving the overall integration and reducing the occupied space.

[0029] By performing corresponding structural optimization on the motor 1, reducer 4, high-frequency transformer and power supply unit 8 during integration, the overall volume after integration is reduced, making it easier to use in mines.

[0030] Among them, a third mounting hole for mounting the scraper flange 6 is provided on the reducer 4, and a plurality of third mounting holes are evenly distributed along the circumference. The mounting angle of the scraper flange 6 can be rotated 180° relative to the rotation axis of the reducer 4. The third mounting holes are evenly distributed along the circumference, and the mounting angle of the scraper flange 6 can be adjusted, thereby adapting to position and angle adjustment when installed on the scraper conveyor.

[0031] Specifically, in order to ensure the power of the motor 1 and the torque transmission effect of the reducer 4, the motor 1 is a permanent magnet synchronous motor, and the speed of the permanent magnet synchronous motor can reach above 600r / min, or below 500r / min. Of course, a permanent magnet synchronous motor with a corresponding speed can be selected based on the power output. The specific speed selection is not limited here. The reducer 4 is a first-stage reducer 4.

[0032] The input voltage of the high-voltage inverter 7 is 10 kV, which meets the power demand of the motor 1 .

[0033] At the same time, the high-voltage inverter 7 has a first mounting surface and a second mounting surface located on both sides of the power output end, and a third mounting surface away from the power output end. The power supply unit 8 is installed on the first mounting surface or the second mounting surface or the third mounting surface. The installation position can be changed according to the space conditions, so as to adapt to the current overall structural installation conditions.

[0034] In order to solve the problem that the chain of the scraper conveyor becomes loose as time goes by, resulting in an unbalanced output between the two motors in the scraper conveyor, it is necessary to control the rotation speed of the motor 1 to achieve chain tensioning.

[0035] Specifically, the motor 1 has a tensioning end, the third output shaft of the motor 1 extends out of the tensioning end, and the first output shaft 2 is coaxially connected to the third output shaft; the motor 1 is provided with a plurality of third mounting holes located at the tensioning end and uniformly distributed along the circumferential direction, the motor 1 is sleeved with a gear unit 9, the gear unit 9 is provided with a fourth mounting hole 10 aligned with the third mounting hole, and a fastener locks the third mounting hole and the fourth mounting hole 10, and a hydraulic motor 11 is provided on the gear unit 9, and an adjusting bolt 12 is integrated on the hydraulic motor 11, and the adjusting bolt 12 is used to adjust the first gear of the hydraulic motor 11 to engage or disengage with the input gear of the gear unit 9, and the output gear of the gear unit 9 is spline-connected to the third output shaft; the first gear of the hydraulic motor 11 is controlled to engage or disengage with the input gear of the gear unit 9 by the adjusting bolt 12. When the motor 1 needs to be decelerated, the reverse force output by the hydraulic motor 11 is used to reduce the speed of the motor 1 until the transmission chain of the scraper conveyor is tensioned.

[0036] Specifically, in order to ensure torque transmission and shorten the connection length, external splines are provided on the first output shaft 2 and the third output shaft, and internal splines are provided on the second output shaft and the output gear of the gear unit 9. By matching the internal splines with the external splines, the torque transmission strength can be met after matching in a shorter length.

[0037] At the same time, the meshing parts of the hydraulic motor 11 and the gears in the gear unit 9 are made of 42CrMo material to ensure that the structural strength can be met when slowing down and tensioning the chain.
