[0106] Embodiment 5

[0107] In the above-mentioned embodiment, a single material frame mechanism 3 is taken as an example, and the storage quantity of materials and the material turnover time are considered to be improved, such as Figure 11-13 As shown, in this embodiment, two material frame mechanisms 3 are provided, and are respectively installed above the carrier 2. Of course, in this embodiment, two lifting mechanisms 4 should also be provided accordingly, for respectively driving the movement of the two material frame mechanisms 3;

[0108] Furthermore, in this embodiment, the rotating plate 56 is rotatably connected to the carrier 2 to achieve adaptation to the two material frame mechanisms 3 .

[0109] In some embodiments, a large gear 21 and a small gear 22 are rotatably connected to the top of the carrier 2, the large gear 21 meshes with the small gear 22, and the large gear 21 is fixed to the bottom plate 56, wherein a rotating motor 23 is also fixed below the carrier 2, and the shaft end of the rotating motor 23 is fixed to the small gear 22. When it is necessary to dock the layer plates 31 on the two material frame mechanisms 3, the rotating motor 23 controls the small gear 22 to rotate, and after the small gear 22 meshes with the large gear 21, the rotation control of the rotating plate 56 is realized, so that the feeding end of the rotating plate 56 can be respectively aligned with the two material frame mechanisms 3, so as to realize the separate taking of the layer plates 31 in the two material frame mechanisms 3, as shown in FIG. Fig.14 Shown is a simplified diagram of the layout of the device and the drilling machine equipment in this embodiment.

[0110] This design allows the layer plate 31 to rotate in any direction after arriving on the loading platform 51. At the same time, a material frame mechanism 3 and a lifting mechanism 4 are added on the other side of the translation mechanism 5. In this way, under the action of the rotating base plate 56, the translation mechanism 5 can dock with any material frame mechanism 3 to realize loading and unloading. This method increases the storage quantity of materials, reduces the material turnover time, indirectly reduces the downtime waiting time of the equipment, and improves the equipment utilization rate. Of course, in other embodiments, the above-mentioned material frame mechanism 3 can be set to three or four, etc., and technical personnel in the relevant field can make adaptive adjustments according to the actual demand quantity and placement position, which will not be elaborated here.

[0111] like Fig.15As shown, in this embodiment, the cutter head method includes the following steps:

[0112] Step 1: Control the mobile device 1 to move to the cutter head replacement position of the corresponding drilling rig;

[0113] Step 2: After the moving device 1 is in place, the lifting mechanism 4 lifts the material frame mechanism 3 along the first direction until the required layer plate 31 moves to the position where it docks with the translation mechanism 5;

[0114] Step 3: The translation mechanism 5 pulls the layer plate 31 in the relative material frame mechanism 3 out along the second direction, so that the layer plate 31 is above the carrier 2;

[0115] Step 4: The material taking mechanism 6 moves between the layer plate 31 and the drilling machine to fill the drilling machine cutter head;

[0116] Wherein, step 4 specifically includes:

[0117] Step 41: the material taking mechanism 6 moves to the position of the old cutter disc on the drilling rig, grabs the old cutter disc, and then returns to place the old cutter disc on the cutter disc temporary storage position on the translation mechanism 5;

[0118] Step 42: the material taking mechanism 6 clamps the new cutter disc on the layer plate 31, and then places the new cutter disc on the original position of the old cutter disc. Thereafter, the material taking mechanism 6 grabs the old cutter disc on the temporary storage position, and then returns to place the old cutter disc on the vacant position of the layer plate 31;

[0119] Step 43: Repeat the above steps until all new cutter discs on the layer plate 31 are removed and replaced with old cutter discs;

[0120] Step 5: The lifting mechanism 4 moves the material frame mechanism along the first direction to another layer 31 filled with new cutter discs and docks with the relative translation mechanism 5. When the cutter discs on the first material frame mechanism 3 are taken out, the second material bin mechanism 3 is started, and the above steps are repeated to replace all the cutter discs required by the drilling rig;

[0121] Step 6: The mobile device 1 moves to the next drilling rig, and repeats the above actions.

[0122] Embodiment 6

[0123] In the above embodiments, the layout of a single mechanical arm is taken as an example. Considering that a single mechanical arm can only replace the cutter head of a single drilling rig, Fig.16As shown, in this embodiment, two material-taking mechanisms 6 are provided, and both are installed on the carrier 2. In addition, one translation mechanism 5 is provided. It should be noted that the translation mechanism 5 can also be rotated as described in Example 5. Three material frame mechanisms 3 are provided, and the three material frame mechanisms 3 are distributed on the side of one translation mechanism 5. Secondly, in the layout of this embodiment, this device should be located between two drilling rigs, and the two material-taking mechanisms 6 are used to take the cutter discs on each material frame mechanism 3, and then the cutter discs on the two drilling rigs are replaced respectively. Under the action of the rotating bottom plate 56, the translation component can be docked with any layer plate 31 to realize loading and unloading. In addition, this scheme adopts dual robotic arms to work. This method increases the storage quantity of materials and reduces the material turnover time; the dual robotic arms work increases the efficiency of material replacement; multiple drilling rigs can be replaced at the same time; the robotic arm 1 and the robotic arm 2 can work independently and have better flexibility. Fig.17 It is the processing flow chart of this device in this embodiment.

[0124] Embodiment 7

[0125] In this embodiment, the structure of the rotating bottom plate 56 is still taken as an example. In the above embodiments, a single translation mechanism 5 is taken as an example. Since the material taking efficiency of the single translation mechanism 5 is limited, Fig.18 , 19 As shown, therefore, in this embodiment, two of the material frame mechanism 3, the translation mechanism 5 and the material taking mechanism 6 are provided, and the two translation mechanisms 5 are used to transfer the cutter discs on the two material frame mechanisms 3 respectively, and move the cutter discs to the drilling rigs through two mechanical arms. Of course, in this embodiment, the device is also arranged between the two drilling rigs to realize the separate feeding of the two drilling rigs. In other embodiments, the material frame mechanism 3 can be provided in multiples with reference to the above embodiments, thereby increasing the storage capacity of the cutter discs. This method increases the storage quantity of materials and reduces the material turnover time; the operation of the dual mechanical arms increases the efficiency of material change; multiple drilling rigs can be changed materials at the same time; sharing a moving device saves space compared to embodiment 1; group 1 and group 2 can work independently and have higher flexibility.
