The container assembly 5 is used for shipping auxiliary materials required by coal mine tunneling working face production, the fork mechanism assembly 4 is used for forking the container assembly 5 and placing the container assembly 5 on the frame assembly 1, the bottom supporting oil cylinder 2 and the top supporting oil cylinder 3 are used for supporting self-loading and unloading devices to keep stable, and the frame assembly 1 is used for installing the fork mechanism assembly 4, the bottom supporting oil cylinder 2 and the top supporting oil cylinder 3 and is used as a mechanism for transporting the container assembly 5.
The frame assembly 1 comprises two parallel girders 6, a 1# fixing device 7, a 2# fixing device 8, a 3# fixing device 9, an anti-collision beam 10, a limiting block 11, a tire 12, a 4# fixing device 13, a 5# fixing device 14 and a front baffle 15. The girder 6 is used for connecting structural members on the frame assembly 1, and the tire 12 mounted on the frame assembly 1 is used for the movement of the whole body.
The # 1 fixing device 7, the # 2 fixing device 8, the # 4 fixing device 13 are fixed on the girder 6 in a welding mode, the top surfaces of the four fixing devices are kept in the same horizontal plane, and the moving device assembly 27 of the fork mechanism assembly 4 is mounted on the four fixing devices through bolts.
The 3# fixing device 9 and the 5# fixing device 14 are welded to the girder 6 by adopting a welding method, the container assembly limiting block 11 is welded on the girder, and four supporting legs of the container are placed on the four limiting blocks 11 to play a role in supporting and limiting. The anti-collision beam 10 is arranged on the girder 6 and is connected with the girder 6 through bolts, so that the container assembly 5 is prevented from being directly collided when the vehicle is reversed or overtaking collision occurs.
The bottom supporting oil cylinder 2 and the top supporting oil cylinder 3 are connected to the 3# fixing device 9 and the 5# fixing device 14 through bolts, when the self-loading and unloading device works, the bottom supporting oil cylinder and the top supporting oil cylinder extend out of the piston rod to support the ground and the top, so that the stability of the self-loading and unloading device is improved, and rollover of the self-loading and unloading device during working is prevented.
The fork-lift mechanism assembly 4 is used to fork a container assembly 5. The lifting cylinder 24 and the gantry 23 are mounted on a slide 30 of the displacement device 27, the slide 30 is connected to one end of a chain 37, and the other end of the chain 37 is connected to the girder 6. The slider 30 is mounted on a cylindrical guide post 32, and the cylindrical guide post 32 is mounted on the girder 6 by a bolt 33 and a guide post pressing block 34. The side pushing cylinder 31 is mounted on the girder 6 through a side pushing cylinder fixing block I36 and a side pushing cylinder fixing block II 38.

The explosion-proof rubber-tyred vehicle is used for parking by pulling the self-loading and unloading device to a proper position of the underground conveying belt rack. An operator controls the bottom supporting oil cylinder 2 and the top supporting oil cylinder 3 to act through a remote controller or a handle, so that the bottom supporting oil cylinder 2 supports the ground, and the top supporting oil cylinder 3 supports the roof of the coal mine tunnel so as to stabilize the whole self-loading and unloading device. Then the lifting oil cylinder 24 on the fork transport mechanism assembly 4 is controlled to lift, the fork 28 and the adjusting oil cylinder 29 are driven to lift, the piston rod head of the adjusting oil cylinder 29 is embedded into the locking sleeve 19 on the container assembly 5, and the container assembly 5 is lifted along with the fork 28 along with the lifting of the lifting oil cylinder 24. When the lifting cylinder 24 is lifted to a proper position, the side pushing cylinder 31 is controlled to act to drive the sliding block 30 and the gantry 23 to move laterally, and the fork 28 moves laterally along with the container assembly 5. When the side pushing oil cylinder 31 reaches the stroke, the adjusting oil cylinder 29 is controlled to act, the adjusting oil cylinder 29 can continuously push the container assembly 5 for a proper distance, the supporting leg position of the container assembly 5 is just positioned at the placement position of the belt frame, at the moment, the adjusting oil cylinder 29 is stopped to act, the lifting oil cylinder 24 is controlled to descend, and the container assembly 5 is completely placed on the belt frame.
When the auxiliary materials used for tunneling working surfaces in the underground container are used up, the underground container runs to the proper position of the belt frame from the loading and unloading device, the vehicle body and the belt frame are kept relatively parallel to each other as much as possible, at the moment, the side pushing oil cylinder 31 is controlled to fork the fork 28 into the middle position of the positioning guide groove, when the side pushing oil cylinder 31 reaches the stroke or the proper position, the lifting oil cylinder 24 is controlled to act, the adjusting oil cylinder 29 is embedded into the locking sleeve 19, then the lifting height is continuously carried out, the whole container assembly 5 is separated from the belt frame, then the adjusting oil cylinder 29 is controlled to act, the container assembly 5 is pulled back to the proper position of the fork 28, and finally the side pushing oil cylinder 31 is controlled to act, and the fork mechanism assembly 4 is retracted back to the self-loading and unloading device.
