[0028] See also Figure 1-4 , the utility model provides a technical solution:

[0029] A coal mine electromechanical transport transmission device includes a base 1, two fixed blocks 2 are fixedly connected to the front and rear ends of the base 1, the upper ends of the four fixed blocks 2 are each provided with a fixing hole 3 that passes through upward and downward, two slide grooves 4 are provided in the middle of the upper end of the base 1, a left mounting block 5 is fixedly connected to the left portion of the upper end of the base 1, a right mounting block 6 is fixedly connected to the right portion of the upper end of the base 1, a control device 7 is inserted and installed on the left end of the left mounting block 5, a mounting assembly 8 is fixedly connected to the upper end of the control device 7, and a transmission belt 9 is fixedly installed on the upper end of the mounting assembly 8.

[0030] In this embodiment, the control device 7 includes a rotating motor 71, a left ball screw 72 is fixedly installed at the output end of the rotating motor 71, a fixing rod 73 is fixedly connected to the right end of the left ball screw 72, a right end of the fixing rod 73 is fixedly connected to the right ball screw 74, the outer surface of the left ball screw 72 and the outer surface of the right ball screw 74 are both threadedly connected with a lifting assembly 75, the right end of the rotating motor 71 is fixedly connected to the left end of the left mounting block 5, the output end of the rotating motor 71 passes through the left end of the left mounting block 5 and extends to the right end of the left mounting block 5; the left ball screw 72 and the right ball screw 74 are left and right mirror images. Distribution, the right end of the right ball screw 74 is movably connected to the left end of the right mounting block 6 through a bearing; the lifting component 75 includes a ball screw block 751, and the lower end of the ball screw block 751 is fixedly connected to a slider 752, the front and rear ends of the ball screw block 751 are movably mounted with lifting plates 753 through bearings, and a top block 754 is movably mounted between the two lifting plates 753 through bearings, and the inner wall surface of the right ball screw block 751 is threadedly connected to the outer surface of the right ball screw 74; the lower part of the slider 752 is movably sleeved in the corresponding slide groove 4, and the upper end of the top block 754 is fixedly connected to the lower end of the mounting component 8.

[0031] By the above scheme: when the rotary motor 71 in the control device 7 is started, the rotary motor 71 drives the left ball screw 72 to rotate. Since the left ball screw 72 is connected to the right ball screw 74 through the fixing rod 73, the rotation of the left ball screw 72 will be synchronously transmitted to the right ball screw 74, so that they rotate synchronously. When the left ball screw 72 and the right ball screw 74 rotate, the ball screw block 751 threadedly connected to them will rotate along the left ball screw 72 according to the rotation direction of the left ball screw 72 and the right ball screw 74. The ball screw 72 and the right ball screw 74 move axially. At the same time, the slider 752 at the lower end of the ball screw block 751 moves in the slide groove 4 on the base 1. As the ball screw block 751 moves, the lifting plate 753 connected to it through the bearing will also rise and fall accordingly. The top block 754 between the two lifting plates 753 is lifted and lowered under the drive of the lifting plates 753. Because the upper end of the top block 754 is fixedly connected to the lower end of the mounting assembly 8, the mounting assembly 8 can change its height as the top block 754 rises and falls.

[0032] In this embodiment, the mounting assembly 8 includes a mounting seat 81 and a balance rod 82. The front and rear ends of the mounting seat 81 are fixedly connected to two balance blocks 83. The upper ends of the four balance blocks 83 are each provided with a movable hole 84 that passes through the upper and lower ends. Four balance rods 82 are provided. The upper ends of the four balance rods 82 are each fixedly connected to a limiting block 85. The lower end of the mounting seat 81 is fixedly connected to the upper end of the top block 754; the lower ends of the four balance rods 82 are respectively fixedly connected to the four corners of the upper end of the base 1, and the four balance rods 82 are respectively movably sleeved in the corresponding four movable holes 84.

[0033] Through the above scheme: during the lifting and lowering process of the mounting seat 81, the balancing blocks 83 at the front and rear ends thereof slide up and down along the balancing rod 82, and finally, the transmission belt 9 installed on the mounting assembly 8 will also be adjusted in height accordingly.

[0034] It should be noted that the present invention is a coal mine electromechanical transportation transmission device. During use, first, the rotating motor 71 is started, and its output end drives the left ball screw 72 to rotate. The left ball screw 72 drives the right ball screw 74 to rotate synchronously through the fixing rod 73. Since the left ball screw 72 and the right ball screw 74 are distributed in left and right mirror images and the outer surfaces are both threadedly connected with the lifting assembly 75, when the left ball screw 72 and the right ball screw 74 rotate, the ball screw block 751 threadedly connected thereto will move along the axial direction of the left ball screw 72 and the right ball screw 74. At the same time, the slider 752 at the lower end of the ball screw block 751 slides in the slide groove 4 to play a guiding and stabilizing role. The movement of the bead wire block 751 and the lifting plate 753 connected thereto through the bearing will drive the top block 754 to rise and fall, and the upper end of the top block 754 is fixedly connected to the mounting seat 81 of the mounting assembly 8, thereby realizing the lifting and lowering adjustment of the mounting seat 81. During the lifting process of the mounting seat 81, the balance blocks 83 at the front and rear ends thereof slide up and down along the balance rod 82. The stability and balance of the lifting of the mounting seat 81 are ensured by the four balance rods 82. Finally, the transmission belt 9 installed on the mounting assembly 8 will also be adjusted in height to adapt to different work requirements and transportation conditions. In this way, the height of the transmission belt 9 can be flexibly and accurately controlled to ensure the efficient and stable electromechanical transportation of the coal mine.
