Description

Technical Field

[0001] The invention relates to the technical field of auxiliary transportation equipment for coal mines, and in particular to a container for automatic transfer of coal mines. Background Art

[0002] At present, in the auxiliary transportation system of coal mines, hydraulic lifting beams are generally used to directly lift containers loaded with materials and equipment through slings for transshipment and transportation of materials and equipment. In places where monorail lifting tracks are not laid or it is inconvenient to lay them, ground rails are laid on the ground, and special mine cars running on the ground rails are used to load containers for relay transportation. When the container is relayed by a special mine car, the container needs to be connected and fixed to the special mine car. At present, the common practice in the industry is: connecting ears with connecting pin holes are set at the four corners below the container, and connecting seats with pin holes are set at the corresponding positions of the four corners at the upper end of the special mine car. When the container is placed on the special mine car, the connecting ears at the four corners below the container cooperate with the connecting seats at the four corners at the upper end of the special mine car, and the connecting pins are manually inserted and locked to fix the container with the special mine car; similarly, when the fixed connection between the container and the special mine car is released, the container and the special mine car are also released by manual reverse steps. Due to structural limitations, existing containers require manual operation in the conversion process between hydraulic lifting beams lifting through hoisting equipment and special mine truck relay transportation. This requires a large number of workers, has low operating efficiency, and is prone to safety accidents. Summary of the invention

During operation, when the guide pin 26 moves from top to bottom or from bottom to top in the spiral groove hole 27-3 of the rotary lock 27, the rotary lock 27 can be rotated 90 degrees in the opposite direction accordingly. The rotation of the rotary lock 27 can make the directions of the conical surface of the lock head 27-2 and the tangent plane 27-2-1 interchangeable.

[0039] See Figures 8 to 10 The working principle and process of the automatic transfer container for coal mines in this embodiment when in use are briefly described as follows:

[0040] When in use, the automatic transfer container for coal mines of this embodiment cooperates with the monorail hoist 101 in the auxiliary transportation system of coal mines and the dedicated mine car 100 running on the ground rail 102, so as to realize the unmanned automatic transfer between the container of this embodiment and the dedicated mine car 100. The dedicated mine car 100 includes a body 100-1, a connecting plate 100-2 fixedly arranged at the four corners of the body 100-1, and a container lower corner member guide seat 100-3 fixedly arranged on the corresponding side of each connecting plate 100-2; each connecting plate 100-2 is provided with a waist-shaped hole 100-2-1 that cooperates with the lock head 27-2 of the rotary lock 27 of the automatic docking mechanism 2. The following is explained in two states.

[0041] First, the container of the present embodiment is converted from the state of being lifted by the monorail to the state of being placed on the special mine car 100: when the monorail system lifts the container of the present embodiment to the top of the special mine car 100 for relay transportation, the monorail lifting device 101 of the monorail system lowers the container onto the special mine car 100, and the monorail lifting device 101 presses down the pressure rod 21 of the automatic docking mechanism 2 at the four corners of the container. The pressure rod 21 is forced to move downward, and the guide pin shaft 26 moves downward in the spiral groove hole 27-3 of the rotary lock 27 through the transmission of the guide rod 22 and the connecting piece 25, so that the rotary lock 27 rotates, and the lock head 27-2 of the rotary lock 27 rotates 90°. At this time, the two tangent planes 27-2-1 of the lock head 27-2 are parallel to the waist-shaped hole 100-2-1 on the connecting plate 100-2 of the special mine car 100, and the four lower corner pieces 11-3 of the container are on the four container lower corner piece guide seats 100- 3, the lock head 27-2 of the rotary lock 27 is aligned with the waist-shaped hole 100-2-1 of the special mining car 100 and smoothly extends through each waist-shaped hole 100-2-1 to the bottom of the vehicle body 100-1; after the monorail hoist 101 places the container on the special mining car 100, the monorail hoist 101 is lifted up and separated from the contact with the container, the pressure on the pressure rod 21 disappears, and the restoring elastic force of the restoring spring 24 drives the guide rod 22, the connecting piece 25 and the guide pin The shaft 26 moves upward, and the lock head 27-2 of the rotary lock 27 rotates 90 degrees, so that the two tangent planes 27-2-1 of the lock head 27-2 and the waist-shaped holes 100-2-1 on the connecting plate 100-2 of the special mine car 100 are changed from parallel to cross directions, so that the container is automatically locked and connected with the special mine car 100, and the four container lower corner fittings guide seats 100-3 of the special mine car 100 also limit the four container lower corner fittings 11-3. At this time, the container can be relayed by the special mine car 100 on the ground rail 102.

[0042] Secondly, the container of this embodiment is converted from the fixed connection state on the special mining car 100 to the monorail lifting state:

[0043] The monorail lifting device 101 of the monorail lifting system moves to above the container, and the monorail lifting system lowers the monorail lifting device 101. During the docking process between the monorail lifting device 101 and the container, the monorail lifting device 101 presses down the pressure rod 21 of the automatic docking mechanism 2 at the four corners of the container. Similar to the aforementioned process, the lock head 27-2 of each rotary lock 27 rotates 90°, and the two tangential planes 27-2-1 of the lock head 27-2 and the waist-shaped hole 100-2-1 of the special mine car 100 are converted from a cross state to a parallel state. The monorail lifting device 101 can lift the container from the special mine car 100, thereby completing the conversion of the container from the transportation state of the special mine car 100 to the lifting state of the monorail lifting system.

[0044] As can be seen from the foregoing, the automatic transfer container for coal mines of this embodiment can automatically dock and lock with the matching special mine car 100 and automatically release the docking and locking state when in use, thereby realizing unmanned transfer between the container and the special mine car 100 in the coal mine auxiliary transportation system, thereby saving manpower, improving work efficiency, and reducing safety accidents.

[0045] The above embodiments are descriptions of specific implementation methods of the present invention rather than limitations of the present invention. Technical personnel in the relevant technical field can make various changes and modifications to obtain corresponding equivalent technical solutions without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should be included in the patent protection scope of the present invention.
