[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-3 The device for monitoring the height of an underground hoist is shown, comprising:

[0026] Positioning box 10;

[0027] Two transmission mechanisms are provided on the positioning box 10;

[0028] The transmission mechanism includes

[0029] The reducer 20 is arranged on the side wall of the positioning box 10, and the output shaft of the reducer 20 extends into the positioning box 10 and is fixedly connected to the first bevel gear 21;

[0030] A threaded rod 40 is rotatably mounted on the upper end wall of the positioning box 10 , and one end of the threaded rod 40 extending into the positioning box 10 has a second bevel gear 41 meshing with the first bevel gear 21 ;

[0031] A lifting sleeve 71 is sleeved on the threaded rod 40 and is threadedly connected to the threaded rod 40;

[0032] The display board 60 is fixedly connected to the upper end wall of the positioning box 10, and the lifting sleeve 71 is slidably connected to the back of the display board 60;

[0033] The two pointers 70 are fixedly connected to the two lifting sleeves 71 respectively. Specific implementation method:

[0035] When the present application is in use, the input ends of the reducers 20 of the two transmission mechanisms are connected to the rotating shafts of the driving rollers of the two hoists through the transmission shafts 30 to achieve transmission;

[0036] The output end of the reducer 20 drives the first bevel gear 21 to rotate, and the first bevel gear 21 drives the second bevel gear 41 to rotate, thereby driving the threaded rod 40 to rotate on the positioning box 10, driving the lifting sleeve 71 to move vertically, and the lifting sleeve 71 drives the pointer 70 to move vertically. At this time, the pointer 70 will point to different positions of the display board 60, thereby realizing the detection of the hopper position.

[0037] This application adopts a mechanized monitoring method and abandons intelligent sensor detection, with low failure rate and high accuracy.

[0038] See also Figure 1 A slide plate 72 is fixedly connected to the lifting sleeve 71 , a vertical guide rail 73 is fixedly connected to the display board 60 , and the slide plate 72 is slidably connected to the guide rail 73 .

[0039] The sliding plate on the lifting sleeve 71 is slidably connected to the guide rail 73 on the display board 60 , so that the lifting sleeve 71 will not rotate along with the threaded rod 40 , thereby achieving vertical movement of the lifting sleeve 71 .

[0040] See also Figure 1 、 2 The upper end of the threaded rod 40 is rotatably connected to the top plate 50, and the top plate 50 is fixedly connected to the display board 60.

[0041] The top plate 50 is fixed to the display plate 60 and is rotatably connected to the threaded rod 40, which can increase the rotation stability of the threaded rod 40.

[0042] See also Figure 1 、 2 The top plate 50 is fixedly connected to the upper end wall of the positioning box 10 via a vertical positioning rod 51.

[0043] The top plate 50 is fixedly connected to the positioning box 10 via the positioning rods 51 , thereby further increasing the stability of the top plate 50 .
