Description

Technical Field

[0001] This utility model relates to the field of pole-mounting manipulator technology, and in particular to an automatic pole-mounting manipulator for a fully hydraulic anchoring drilling rig. Background Technology

[0002] Anchoring drilling rigs are mainly used in landslide and unstable rock mass anchoring projects for various geological disaster prevention and control in hydropower stations, railways, and highway slopes. For example, the automatic rod-mounting manipulator of the fully hydraulic anchoring drilling rig disclosed in Chinese patent application number CN201320564221.2 is as follows: When clamping the drill rod, the rotary motor drives the rotary support to lower to a suitable height, and then the rotary cylinder adjusts the rotary support to a horizontal position of the drill rod frame. Then, the action of the arm cylinder completes the gripping of the drill rod. After this action is completed, the rotary motor is activated to lift the rotary support. This action stops when the center of the drill rod is coaxial with the main shaft of the drilling rig power head. Then, the sliding cylinder assists the power head to complete the rod-mounting action. The rod-unloading action is the reverse of this action. However, it still has the following technical problems:

[0003] Because the models and configurations of anchoring drilling rigs differ, the installation position of the upper rod manipulator varies. However, in the aforementioned structure, the dimensions of the main frame and the rotary support cannot be adjusted. This causes a misalignment between the manipulator and the drill rod after the rotary motor lowers the rotary support and the rotary cylinder adjusts the rotary support. Consequently, the manipulator struggles to grip the drill rod. Utility Model Content

[0004] To address the problem mentioned in the background art that the robotic arm has difficulty grasping the drill rod when there is a positional deviation between the robotic arm and the drill rod, this utility model provides the following technical solution:

[0005] An automatic rod-raising manipulator for a fully hydraulic anchoring drilling rig includes a fixed plate, a connecting frame, a support frame, and a rotating bracket.

[0006] The upper end of the rotating bracket is equipped with a clamping arm for clamping the drill rod, the side of the connecting frame one near the fixed plate is equipped with a sliding oil cylinder, and the upper end of the support frame one is equipped with a rotating rod.

[0007] A connecting frame three is installed in the middle of the rotating rod, and a support frame two for limiting the rotation bracket is installed on one side of the connecting frame three.

[0008] Furthermore, a rotary motor for controlling the rotation of the rotary rod is installed on one side of the rotary rod, and a rotary cylinder is connected to the side of the rotary bracket near the second support frame.

[0009] Furthermore, the connecting frame three is equipped with a plug rod on the side facing the support frame two, which facilitates the adjustment of the distance between the connecting frame three and the support frame two, and the plug rod has multiple threaded holes on its outer side.

[0010] Furthermore, a connecting sleeve is installed on the side of the support frame two facing the connecting frame three, and a limiting hole for limiting the insertion rod is opened on the side of the connecting sleeve facing the insertion rod.

[0011] Furthermore, a retaining ring two is installed on the outer side of the connecting sleeve, and a screw for limiting the insertion rod by engaging with a threaded hole is installed in the middle of the retaining ring two.

[0012] Furthermore, a connecting frame two is installed at the lower end of the first support frame, and multiple slots are provided at the upper end of the second connecting frame.

[0013] Furthermore, a limiting lever is installed in the middle of the screw. The limiting lever includes a long rod. A retaining ring is installed at the upper end of the long rod for engaging with the retaining ring two. A connecting rod is installed at the lower end of the long rod. A locking block is installed at the lower end of one side of the connecting rod for engaging with the retaining groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When installing this invention on anchoring drilling machines of different sizes, first fix the fixing plate on the anchoring drilling machine, install the second support frame on one side of the third connecting frame, insert the insertion rod into the limiting hole, and screw the screw into the corresponding threaded hole according to the position of the drill rod. Before tightening the screw, a retaining ring is placed on the outside of the screw. Adjust the engagement position of the first and second retaining rings so that when the rotating bracket is adjusted to the horizontal position of the drill rod frame, the retaining block engages in the corresponding slot. After adjustment, tighten the screw so that the first and second retaining rings are locked together, and the screw fixes the connecting sleeve to the insertion rod. Through the engagement of the retaining block and the slot, the weight of the drill rod will not excessively press down on the rotating bracket when the clamping arm grips the drill rod. The limiting retaining rod then protects the rotary motor, avoiding damage to the rotary motor and thus increasing the service life of the rotary motor. Attached Figure Description

Detailed Implementation

[0021] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0022] Please see Figures 1-3 This utility model provides an automatic rod-mounting robot for a fully hydraulic anchoring drilling rig, including a fixed plate 1, a connecting frame 3, a support frame 4, and a rotating bracket 10. A sliding cylinder 2 is installed on the side of the connecting frame 3 near the fixed plate 1. A clamping arm 11 for clamping the drill rod is installed on the upper end of the rotating bracket 10, and an arm cylinder is installed on the lower end of the clamping arm 11. The arm cylinder is existing technology and can control the clamping arm 11 to grasp the drill rod.

[0023] A rotating rod 5 is movably mounted on the upper end of the support frame 4. A rotary motor 6 for controlling the rotation of the rotating rod 5 is mounted on one side of the rotating rod 5. A connecting frame 7 is fixedly mounted in the middle of the rotating rod 5. There are two connecting frames 7, located on both sides of the rotating rod 5. A support frame 8 for limiting the rotation of the rotating bracket 10 is mounted on one side of the connecting frame 7. When the rotary motor 6 controls the rotating rod 5 to rotate, the connecting frame 7 drives the support frame 8 to rotate synchronously, which facilitates the lowering of the support frame 8.

[0024] A rotary cylinder 12 is movably connected to the side of the rotary support 10 near the support frame 8. The rotary cylinder 12 is used to control the rotary support 10 to adjust to the horizontal position of the drill rod frame so that the clamping arm 11 can grasp the drill rod.

[0025] A rod 71 is fixedly installed on the side of the connecting frame 3 7 facing the support frame 2 8 to facilitate the adjustment of the distance between the connecting frame 3 7 and the support frame 2 8. Multiple threaded holes 72 are provided on the outer side of the rod 71. The multiple threaded holes 72 facilitate the fixing of the connecting frame 3 7 and the support frame 2 8 at different distances. This allows the present invention to adjust the position of the rotating bracket 10 according to the anchoring drilling machine of different sizes, so as to facilitate the clamping arm 11 to grasp the drill rod.

[0026] A connecting sleeve 81 is fixedly installed on the side of the support frame 2 8 facing the connecting frame 3 7. A limiting hole 82 for limiting the insertion rod 71 is opened on the side of the connecting sleeve 81 facing the insertion rod 71. The insertion rod 71 can extend and retract within the limiting hole 82. A retaining ring 2 83 is fixedly installed on the outside of the connecting sleeve 81. A screw 84 for limiting the insertion rod 71 by engaging with the threaded hole 72 is installed in the middle of the retaining ring 2 83. The screw 84 passes through the middle of the retaining ring 2 83, and the threaded end of the screw 84 can extend into the limiting hole 82 so that the threaded end of the screw 84 can be screwed into the threaded hole 72, thereby fixing the support frame 2 8 on the connecting frame 3 7, so that when the connecting frame 3 7 rotates, it drives the support frame 2 8 to move synchronously.

[0027] A connecting frame 41 is fixedly installed on the side of the support frame 1 4 facing the support frame 2 8. Multiple slots 42 are provided on the upper end of the connecting frame 2 41.

[0028] A limiting rod 9 is installed in the middle of the screw 84. The limiting rod 9 includes a long rod 91. A retaining ring 92 for engaging with the retaining ring 83 is fixedly installed at the upper end of the long rod 91. The screw 84 passes through the middle cavity of the retaining ring 92. A connecting rod 93 is fixedly installed at the lower end of the long rod 91. A locking block 94 for engaging with the retaining groove 42 is fixedly installed on one side of the lower end of the connecting rod 93.

[0029] When installing this utility model on anchoring drilling machines of different sizes, first fix the fixing plate 1 on the anchoring drilling machine, install the support frame 2 8 on one side of the connecting frame 3 7, insert the insertion rod 71 into the limiting hole 82, and screw the screw 84 into the corresponding threaded hole 72 according to the position of the drill rod. Before tightening the screw 84, the retaining ring 92 is fitted onto the outside of the screw 84. The engagement position of the retaining ring 92 and the retaining ring 83 is adjusted so that when the rotating bracket 10 is adjusted to the horizontal position of the drill rod frame, the retaining block 94 is engaged in the corresponding slot 42. After adjustment, the screw 84 is tightened so that the retaining ring 92 and the retaining ring 83 are locked together. The screw 84 fixes the connecting sleeve 81 to the insert rod 71. Through the engagement of the retaining block 94 and the slot 42, the weight of the drill rod will not excessively press down on the rotating bracket 10 when the clamping arm 11 grips the drill rod. The limiting rod 9 then protects the rotary motor 6, avoiding damage to the rotary motor 6 and thus increasing the service life of the rotary motor 6.

[0030] When clamping the drill rod, the rotary motor 6 drives the connecting frame 3 7 and the support frame 2 8 to lower until the clamping block 94 and the clamping slot 42 engage. The rotary cylinder 12 controls the rotary support 10 to adjust to the horizontal position of the drill rod frame. The existing arm cylinder controls the clamping arm 11 to grab the drill rod. Then, the rotary motor 6 controls the connecting frame 3 7 and the support frame 2 8 to lift the rotary support 10, so that the center of the drill rod is coaxial with the main shaft of the drilling rig power head. Finally, the sliding cylinder 2 assists the power head to complete the rod loading action, and the rod unloading action is the opposite of this action.

[0031] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
