DETAILED DESCRIPTION

[0020] In order to better understand the utility model, the content of the utility model will be further clearly explained in combination with the embodiments below, but the protection content of the utility model is not limited to the following embodiments only. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details.

[0021] As Figure 1 , 4As shown, the device includes a mounting bracket 101, a rotating platform 103 on the upper surface of the mounting bracket 101, a rotating shaft 209 rotatably mounted inside the rotating platform 103, a rotating box 104 at the top of the rotating shaft 209, a rotating seat 105 in the middle of the rotating box 104, a rotating frame 106 rotatably mounted inside the rotating seat 105, a broadcast box 107 at the end of the rotating frame 106 away from the rotating box 104, and a speaker module 108 in the clearance groove in the middle of the broadcast box 107. Two symmetrically distributed sliding sleeves 201 are provided on the side wall of the rotating box 104. A sliding frame 202 is slidably arranged between the sliding sleeves 201. The side of the sliding frame 202 away from the rotating box 104 is connected and fixed to the broadcast box 107. A quarter-tooth external gear ring 203 is provided on the side of the sliding frame 202 located inside the rotating box 104. A rotating shaft 204 is rotatably arranged inside the rotating box 104. A gear 205 is fixedly sleeved on the outer arc surface of the rotating shaft 204. The gear 205 meshes with the quarter-tooth external gear ring 203.

[0022] like Figure 2 , 3 As shown, a worm gear 206 is fixedly sleeved on the outer arc surface of the rotating shaft 204, and a worm 207 is rotatably installed inside the rotating box 104. The worm 207 is meshed with the worm gear 206. A motor 208 is installed on the inner side wall of the rotating box 104, and the output shaft of the motor 208 is fixed to the worm 207 by a coupling.

[0023] like Figure 2 , 3 As shown, a worm gear 211 is fixedly sleeved on the outer arc surface of the rotating shaft 209. A mounting base 210 is provided on the inner wall of the rotating table 103. A worm gear 212 is rotatably mounted inside the mounting base 210. The worm gear 212 is meshed with the worm wheel 211. A motor 213 is provided on the mounting base 210. The output shaft of the motor 213 is fixed to the worm gear 212 by a coupling.

[0024] like Figure 2 , 4 As shown, a control box 301 is installed on the rotating box 104, and the horn module 108, motor 1 208 and motor 2 213 are all electrically connected to the control box 301.

[0025] During use, the control box 301 is connected to the external intelligent control system of the mine hoist, and then the control box 301 controls the operation of the horn module 108, so that the horn module 108 broadcasts the current operating status of the hoist in the external intelligent control system of the mine hoist (such as start, stop, rise, fall, etc.); during the broadcast, the control box 301 controls the operation of motor 1 208 and motor 2 213.

[0026] The output shaft of motor 208 drives the worm gear 207 connected to it to rotate in both directions. Then, through the meshing relationship between worm gear 207 and worm wheel 206, the rotating shaft 204 where worm wheel 206 is located is rotated. Through the meshing relationship between gear 205 in the middle of the outer arc surface of rotating shaft 204 and quarter external gear ring 203, the sliding frame 202 where quarter external gear ring 203 is located slides between sliding sleeves 201. At this time, rotating frame 106 rotates inside rotating seat 105. Through the cooperation between sliding frame 202 and sliding sleeve 201, the broadcast box 107 is driven to swing up and down around rotating seat 105 as the center.

[0027] The output shaft of motor 213 drives the worm gear 212 connected to it to rotate in both directions. In turn, through the meshing relationship between worm gear 212 and worm wheel 211, the rotating shaft 209 where worm wheel 211 is located is rotated. This causes the rotating shaft 209 to drive the rotating box 104 and the rotating table 103 to rotate, which in turn causes the broadcast box 107 to swing back and forth about the rotating shaft 209 as the center.

[0028] With the cooperation of motor 1 208 and motor 2 213, the horizontal and vertical orientation of the voice broadcast box 107 can be adjusted during use, so that the sound can be directly transmitted to the ears of the operator or on-site staff, reducing the impact of background noise on the clarity of the voice.

[0029] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, mounting bracket 101 has fixing plates 102 on both sides, and each fixing plate 102 has symmetrically distributed mounting holes. Rubber pads are glued to the side of the fixing plate 102 away from the rotating box 104. During installation, bolts are passed through the mounting holes and tightened using external tools to fix the fixing plate 102 in the designated position. The rubber pads provide cushioning between the wall and the fixing plate 102 during installation, preventing damage to the fixing plate 102.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
