DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figure 1-5 , the utility model provides a technical solution:

[0037] A drilling rig rod drop protection device includes a mechanical gripper 101 for gripping a drill rod 100, and further includes:

[0038] The drill arm unit 1 includes a drill frame 11 for mounting a mechanical gripper 101;

[0039] The rod storage unit 2 includes a rod storage assembly 21 provided on one side of the drill rack 11 for storing multiple drill rods, and a protection assembly 22 extending from the bottom of the rod storage assembly 21 to the side of the drill rack 11 for protecting the bottom of the drill rod when the mechanical gripper 101 grabs the drill rod.

[0040] It should be noted that: when replacing the drill rod component 100, the mechanical gripper 101 clamps the drill rod component 100 on the drill rig 11 and sends it to the storage rod assembly 21, and then clamps the new drill rod component 100 in the storage rod assembly 21 and sends it to the drill rig 11 for installation. If the mechanical gripper 101 transfers the drill rod component 100 between the drill rig 11 and the storage rod assembly 21, and the drill rod component 100 slips out of the mechanical gripper 101, the fallen drill rod component 100 is supported by the protective assembly 22, and then the fallen drill rod component 100 is re-clamped and transferred by the mechanical gripper 101, thereby effectively preventing the fallen drill rod component 100 from damaging other auxiliary equipment.

[0041] It should be added that the mechanical gripper 101 can perform the actions of clamping, moving and adjusting the drill rod 100 up and down, left and right, and forward and backward, as well as swinging through a set program.

[0042] As an improvement, Figure 1-3 As shown, the storage rod assembly 21 includes:

[0043] The fixed block 211 is connected to one side of the upper portion of the drill frame 11 through the support arm 14;

[0044] The upper portion of the rotating shaft 212 is rotatably connected to the interior of the fixed block 211. The interior of the fixed block 211 is provided with a motor for driving the rotating shaft 212 to rotate;

[0045] The rod storage bin 213 is provided at the lower end of the rotating shaft 212. The lower end of the rotating shaft 212 is rotatably connected to the inside of the rod storage bin 213. The upper end of the rod storage bin 213 is provided with a second limiting hole 2133 for limiting the lower end of the rotating shaft 212.

[0046] The supporting plate 2121 is fixedly sleeved on the outside of the rotating shaft 212 and located above the rod storage bin 213 , and is used to support the lower end of the drill rod 100 in the rod storage bin 213 .

[0047] Further, such as Figure 2-5As shown, a first limiting ring 2111 for limiting the upper end of the drill rod 100 is fixedly connected to the lower edge of the fixing block 211. The first limiting ring 2111 is located on one side of the drill frame 11 and is provided with a first rod outlet 2112.

[0048] A second limiting ring 2131 is fixedly connected to the upper edge of the rod storage bin 213 to limit the lower end of the drill rod member 100. The plane where the upper end of the second limiting ring 2131 is located is higher than the plane where the upper end of the supporting plate 2121 is located. The second limiting ring 2131 is located on one side of the drill frame 11 and is provided with a second rod outlet 2132 for cooperating with the first rod outlet 2112 to guide the drill rod member 100 in the rod storage bin 213.

[0049] Furthermore, a limiting plate 214 is fixedly provided on the outer side of the rotating shaft 212 and located on the upper end of the carrying plate 2121;

[0050] The outer side of the limiting plate 214 is provided with limiting grooves 2141 at equal angles for spacing multiple drill rods.

[0051] As an improvement, Figure 2-4 As shown, the protection component 22 includes:

[0052] A baffle 221 is fixedly connected at one end to one side of the rod storage bin 213 and at the other end to one side of the baffle 221. The upper end surface of the baffle 221 is in the same horizontal plane as the upper end of the rod storage bin 213, and is used to protect the drill rod 100 during the gripping process of the mechanical gripper 101.

[0053] The baffles 222 are provided in two groups and are fixedly connected to the upper edge of the baffle 221 to limit the bottom of the drill rod 100 that falls on the baffle 221.

[0054] Furthermore, the drill rod 100 further includes:

[0055] The protective bracket 223 surrounds the outside of the storage rod assembly 21 , and both ends of the protective bracket 223 are fixedly connected to both sides of the drill frame 11 to limit the upper part of the drill rod 100 that falls on the baffle 221 .

[0056] Furthermore, Figure 1 As shown, the drill arm unit 1 also includes:

[0057] The power head 12 is provided on the upper part of the drill frame 11, and the lower end of the power head 12 is provided with a connector 13 for connecting the upper part of the drill rod 100 after the rod is replaced;

[0058] The loading and unloading platform 15 is provided on the side of the drill frame 11. A first limiting hole 151 is provided inside the loading and unloading platform 15 for limiting the outer portion of the drill rod 100 after the rod is replaced.

[0059] It should be noted that: in the specific implementation process of this utility model, Figure 1-5 As shown, when the drill rod 100 installed at the lower part of the connecting head 13 is replaced, the mechanical gripper 101 disassembles the drill rod 100 at the lower part of the connecting head 13 and sends it into the rod storage bin 213 through the top of the baffle 221, so that the replaced drill rod 100 is inserted into the vacant limiting groove 2141. Subsequently, the motor in the fixing block 211 is started, and the motor drives the supporting plate 2121 and the limiting plate 214 to rotate synchronously through the rotating shaft 212, so that the supporting plate 2121 and the limiting plate 214 cooperate to switch the next group of new drill rods 100 to the second rod outlet 2132. At this time, the mechanical gripper 101 clamps the new drill rod 100 and transfers it to the connecting head 13 through the top of the baffle 221, completing the installation of the new drill rod 100, thereby completing the work of automatically replacing the drill rod 100.

[0060] like Figure 1-4 As shown, during the transfer of the drill rod 100 by the mechanical gripper 101, if the mechanical gripper 101 suddenly fails, causing the drill rod 100 to fall from the mechanical gripper 101, a baffle 221 is provided between the rod storage bin 213 and the drill rack 11. The baffle 221 can support the fallen drill rod 100. After the mechanical gripper 101 is repaired, the drill rod 100 supported by the baffle 221 can be clamped by the mechanical gripper 101, thereby preventing the fallen drill rod 100 from damaging other auxiliary equipment on one side of the drill rack 11.

[0061] like Figure 1-2 As shown, in addition, the utility model fixes the two sides of the drill frame 11 to the protective bracket 223 and provides a baffle 222 at the upper edge of the baffle 221. When the drill rod member 100 falls on the upper end of the baffle 221, the lower end of the drill rod member 100 is limited by the baffle 222. At the same time, the upper part of the drill rod member 100 is limited by the protective bracket 223 to prevent the drill rod member 100 from tipping over after falling, thereby further reducing the safety hazard caused by the falling of the drill rod member 100.

[0062] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.
