[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0026] A mine air heating unit, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a base plate 10, and a swing assembly is arranged above the base plate 10. The swing assembly includes a linkage seat 17, a bevel gear column 18, a rotating shaft 21 and a bevel gear 22. The linkage seat 17 and the rotating shaft 21 are both rotatably connected to the base plate 10, the bevel gear column 18 is rotatably connected to the linkage seat 17, the bevel gear 22 is fixedly connected to the rotating shaft 21, and the bevel gear column 18 is transmission-connected to the bevel gear 22; as shown Figure 1 As shown, a universal wheel 11 is fixed to the bottom of the base plate 10 by bolts, and four universal wheels 11 are provided and respectively located at the four corners of the base plate 10 .

[0027] The working principle is as follows. When using the device, the linkage seat 17 can be used to rotate at a certain angle. At the same time, the rotation of the rotating shaft 21 drives the bevel gear 22 to rotate, so that the bevel gear 22 engages with the bevel gear column 18, thereby rotating the bevel gear column 18, thereby realizing rotation, and the universal wheel 11 at the bottom of the base plate 10 can drive the entire device to move.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a support seat 13 is fixedly connected to the top of the bottom plate 10, and two support seats 13 are symmetrically arranged. A motor 15 is symmetrically placed on the top of the bottom plate 10, and the two motors 15 are arranged opposite to the two support seats 13; Figure 2 , Figure 3 and Figure 4 As shown, a through hole 14 is opened inside the support seat 13, and a sleeve 16 is rotatably connected inside one of the through holes 14, an output end of one of the motors 15 is connected to one end of the sleeve 16, and the other end of the sleeve 16 is rotatably connected to the rotating shaft 21; Figure 2 , Figure 3 and Figure 4 As shown, one end of the rotating shaft 21 is a short column with a diameter less than or equal to the through hole 14, and the other end is a long column with a diameter less than or equal to the inner circle of the sleeve 16. The long column is rotatably connected to the sleeve 16, and the short column is rotatably connected to another support seat 13 through the through hole 14. The output end of another motor 15 is connected to the short column end of the rotating shaft 21; Figure 3 and Figure 4 As shown, the linkage seat 17 is a U-shaped structure, and rotation holes 19 are symmetrically opened inside the linkage seat 17. The sleeve 16 is fixedly connected to the linkage seat 17 through one of the rotation holes 19, and the linkage seat 17 is rotationally connected to the short column of the rotating shaft 21 through the other rotation hole 19.

[0029] The working principle is as follows: a bearing of the same size is arranged in the through hole 14, one of which 13 is rotatably connected to the sleeve 16 through the bearing in the through hole 14 opened by itself, the interior of the sleeve 16 is a cylindrical hole, and a shaft ring is arranged in the cylindrical hole, and the function of the shaft ring is consistent with that of the bearing, the sleeve 16 is rotatably connected to the long column of the rotating shaft 21 through the shaft ring, and the other 13 is rotated through the bearing in the through hole 14 to rotate the short column of the rotating shaft 21, the linkage seat 17 is a U-shaped structure, and the bottom of the linkage seat 17 is a semicircular arc surface, and the linkage seat 17 has two symmetrically opened rotating holes 1 9 has a diameter greater than or equal to that of the sleeve 16 and the short column of the rotating shaft 21, wherein the diameter of the rotating hole 19 is greater than or equal to the through hole 14, the outer ring diameter of the sleeve 16 is equal to the diameter of the short column of the rotating shaft 21, the outer ring of the sleeve 16 engages with the rotating hole 19, and the linkage seat 17 is welded to the outer ring of the sleeve 16 through one of the rotating holes 19. Since the diameter of the other rotating hole 19 is greater than or equal to the short column of the rotating shaft 21, the linkage seat 17 can be rotatably connected to the rotating shaft 21 with the aid of the other rotating hole 19 and the short column of the rotating shaft 21 is clamped by the other rotating hole 19.

[0030] like Figure 1 , Figure 3 and Figure 5 As shown, a movable hole 20 is opened at the top of the linkage seat 17, and the linkage seat 17 is rotatably connected to the bevel gear column 18 through the movable hole 20. The bevel gear column 18 is meshed with the bevel gear 22, and the top of the bevel gear column 18 is fixedly connected to the heating unit body 12.

[0031] The specific implementation is as follows. When in use, the motor 15 connected to the sleeve 16 is started. Under the urging of the motor 15, the sleeve 16 will rotate. Due to the existence of the bottom plate 10, the linkage seat 17 connected to the sleeve 16 and the heating unit body 12 above the linkage seat 17 will be restricted, which makes the rotation direction of the sleeve 16 fixed and can only achieve 90-degree rotation or 180-degree rotation. Here, the motor 15 is equipped with a motor driver and realizes forward and reverse rotation through PWM control, which can ensure that the sleeve 16 can achieve a certain angle of reciprocating rotation, open the rotation axis The motor 15 connected to the rotating shaft 21 is a rotating motor without a motor driver and only rotates 360 degrees. When the motor 15 connected to the rotating shaft 21 is started, the rotating shaft 21 will rotate, and at the same time, the bevel gear 22 will also rotate. At this time, the bevel gear 22 will mesh with the bevel gear column 18, driving the bevel gear column 18 to rotate, thereby driving the heating unit body 12 connected above the bevel gear column 18 to achieve 360-degree rotation; which motor 15 is turned on here is determined according to the angle and direction of heating required, and the height of the linkage seat 17 When rotating, it can be ensured that it is not blocked by the support seat 13. At the same time, due to the fixed connection between the bevel gear column 18 and the heating unit body 12, the heating unit body 12 does not need to achieve a large angle of rotation. Therefore, when in use, the rotating shaft 21 can be started first, and then the bevel gear column 18 drives the heating unit body 12 to determine a suitable angle, and then the sleeve 16 drives the linkage seat 17 to determine the angle in another direction; the device uses the bottom plate 10 to cooperate with the swing component to fix the heating unit body 12, and then uses the universal wheel 11 to realize the position movement of the heating unit body 12 , which can prevent the heating unit body 12 from contacting the ground and reduce the wear caused by the transfer, while ensuring the long-term use of the device; in addition, the swing component uses a motor 15 that can control the forward and reverse rotation to drive the linkage seat 17 to swing back and forth, and then uses another motor 15 that does not perform forward and reverse rotation to drive the rotating shaft 21 to rotate, and uses the engagement of the bevel gear 22 and the bevel gear column 18 to achieve 360-degree rotation, so as to meet the needs of heating at different angles, which not only makes up for the deficiency of heating in a single direction, realizes multi-directional heating, but also improves the overall use range of the device.
