[0022] Please refer to the instruction manual Figure 1-5 As shown, the utility model provides a technical solution: a training and teaching device for the ten special types of work in underground coal mines, comprising a training chamber 1 and a locking mechanism 8, a seat 2 is arranged inside the training chamber 1, a monitor 3 is arranged above one side of the seat 2, the inner wall of the training chamber 1 is rotatably connected with a pad 4 through a hinge, a rotatable semicircular rotating block 5 is arranged above the pad 4, a control panel 6 is arranged on the other side of the seat 2, a hydraulic gear lever 7 is installed on the upper surface of the control panel 6, a locking mechanism 8 is arranged on the outer side of the hydraulic gear lever 7, a display screen 10 is movably connected with the upper side of the training chamber 1 through a support frame 9, and an armrest 11 is fixedly arranged on one side of the display screen 10.

[0023] As the instruction manual Figure 4-5 As shown, the locking mechanism 8 includes a locking plate 81, a fixed frame 82, a sliding block 83, a push rod 84, a movable rod 85 and a spring 86. The locking plate 81 is arranged on the outer side of the hydraulic lever 7. A groove matching the hydraulic lever 7 is opened on the locking plate 81. The locking plate 81 is fixedly connected to the sliding block 83 through a through groove on one side of the fixed frame 82. The sliding block 83 is fixedly connected to the push rod 84 passing through the fixed frame 82. The top of the fixed frame 82 is rotatably connected with the movable rod 85. The spring 86 is arranged between the sliding block 83 and the fixed frame 82. A sliding groove is opened on the surface of the sliding block 83. The bottom end of one side of the movable rod 85 is provided with a groove that can be moved in the sliding block 83. The movable protrusion in the surface slide groove and the inner wall side of the fixed frame 82 are provided with a groove for the sliding block 83 to slide. When the push rod 84 is pressed, the sliding block 83 slides along the slide groove of the inner wall of the fixed frame 82, compressing the spring 86. At the same time, the protrusion on one side of the movable rod 85 moves along the slide groove on the surface of the sliding block 83. The slide groove has an inward depression, which serves as a limit for the protrusion. The sliding block 83 drives the locking plate 81 to move, and the hydraulic gear lever 7 is stuck in the groove of the locking plate 81 to prevent accidental touch. When the push rod 84 is pressed again, the movable rod 85 returns to its original position because the central axis of the sliding block 83 does not coincide with that of the movable rod 85, thereby releasing the lock on the hydraulic gear lever 7.

[0024] As the instruction manual Figure 1-3As shown, the support frame 9 is composed of four sections, and the joints are connected by damping hinges. The display screen 10 can be pulled up by the armrests 11 fixed on both sides of the display screen 10. The damping hinge can make the display screen 10 hover near the trainee. The rotating block 5 limits the pad 4. By rotating the rotating block 5, the pad 4 can be put down, which is convenient for the use of the mouse during theoretical testing.

[0025] Working principle: First, move a practical training and teaching examination device for the ten special types of work in coal mines to the working position. In the first step, rotate the rotating block 5, put down the pad 4, adjust the display screen 10 to a suitable position through the armrest 11, and conduct a theoretical test. In the second step, adjust the display screen 10 back to its original position, press the push rod 84, and the sliding block 83 slides along the slide groove on the inner wall of the fixed frame 82 to compress the spring 86. At the same time, the protrusion on one side of the movable rod 85 moves along the slide groove on the surface of the sliding block 83. The slide groove has an inward depression, which limits the protrusion. The sliding block 83 drives the locking plate 81 to move, unlocks the hydraulic gear lever 7, and conducts a practical test. In the third step, press the push rod 84 again to lock the hydraulic gear lever 7. This completes the use process of a practical training and teaching examination device for the ten special types of work in coal mines.

[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
