Detailed Embodiment

[0018] This application provides a drilling construction mechanism and its drilling construction equipment. Please refer to Figures 1-11 : including; Main frame 1; used for carrying the drill pipe 2; End cover 3; used for carrying and sealing both ends of the drill pipe 2; Spiral plate 4; a spiral open cavity 5 is formed inside the spiral plate 4, and the drill pipes 2 are successively filled in the spiral open cavity 5; Chuck 6; the chuck 6 clamps both ends of the drill pipe 2, and the chuck 6 moves along the spiral open cavity 5; The positioning head 7; fixes the drill pipe 2 to the end cap 3.

[0019] Specifically, in actual application, during manufacturing, the height, number of turns, and slit width of the spiral plate 4 can be designed according to the specific working conditions to make the spiral plate 4 better match the drill pipe 2; Figure 10 In it, the distribution of the drill pipes 2 is relatively sparse, and the distribution of the drill pipes 2 can be appropriately densified according to actual needs.

[0020] The chuck 6 is divided into a conical chuck 61 and a flared chuck 62. The conical chuck 61 clamps the upper end of the drill pipe 2, and the flared chuck 62 bears the lower end of the drill pipe 2. The main frame 1 is used to connect the drilling rig and the drilling construction mechanism, and at the same time plays a role in bearing the drill pipe 2; the end caps 3 are arranged at both ends of the main frame 1, and the distance thereof matches the length of the drill pipe 2; during use, the drill pipe 2 can be manually or automatically moved to the position of the outer opening of the spiral plate 4, and then gradually moved inward along the extending direction of the spiral plate 4, and its moving path is spiral until it moves to the innermost; Repeat the above operations, and successively place the second, third drill pipes 2 into the spiral open cavity 5 until the spiral open cavity 5 is filled. In the existing technology, the storage capacity of the drill pipes is approximately about 5. Through the spiral placement, the capacity of the drilling construction mechanism for the drill pipes 2 can be greatly increased, about 15 - 40; the drill pipe 2 can be automatically clamped and moved through the movement of the chuck 6; when the drill pipe 2 moves into place, the drill pipe 2 can be fixed by the action of the positioning head 7 to prevent the drill pipe 2 from shaking.

[0021] Refer to Figures 2-8 , including a clamping assembly 8, and the clamping assembly 8 includes; A spiral hole 81, the spiral hole 81 is arranged on the end cap 3, and the spiral hole 81 has the same curvature as the spiral plate 4; An arc-shaped slider 82, the arc-shaped slider 82 is slidably connected to the spiral hole 81, and the arc-shaped slider 82 has the same curvature as the spiral hole 81; A first hydraulic rod 83, the first hydraulic rod 83 is fixedly connected to the arc-shaped slider 82; The chuck 6 is fixedly installed at the telescopic end of the first hydraulic rod 83; A pedestal 84, a first cavity 841 for placing the drill bit is provided at the upper end of the pedestal 84, a second cavity 842 for accommodating the chuck 6 is provided at the lower end of the pedestal 84, and a first round hole 843 for the chuck 6 to pass vertically is opened between the first cavity 841 and the second cavity 842, and the diameter of the first round hole 843 is larger than the diameter of the chuck 6, An arc-shaped channel 85, the arc-shaped channel 85 divides the pedestal 84 into left and right parts for the first hydraulic rod 83 to pass horizontally. The extending path of the arc-shaped channel 85 is the same as the moving path of the drill pipe 2, and a rectangular opening 86 for the chuck 6 to pass horizontally is opened at the lower end of the pedestal 84.

[0022] Specifically in practical applications, a limiting structure is provided between the arc-shaped slider 82 and the spiral hole 81. The arc-shaped slider 82 can only slide along the spiral hole 81. When the drilling construction mechanism is working properly, it is in a vertical state. The chuck 6 is divided into upper and lower parts. The drill pipe 2 can be moved to the designated position (the position of the chuck 6) outside the opening of the spiral plate 4 by an external robotic arm. The extension line of the drill pipe 2 and the connection line between the two chucks 6 are in a straight line. Then, control the first hydraulic rod 83 to extend. The extension of the first hydraulic rod 83 drives the chuck 6 to move towards the position of the drill pipe 2 until the drill pipe 2 is clamped. Since the drill pipe 2 needs to move later, to avoid mutual interference, the height of the drill pipe 2 during movement is higher than the height of the drill pipe 2 placed on the pedestal 84; The side wall of the arc-shaped slider 82 is in a state of being in contact with the side wall of the spiral hole 81, and their curvatures are in a consistent state. The arc-shaped slider 82 can slide within the spiral hole 81. The movement of the arc-shaped slider 82 indirectly drives the drill pipe 2 to move within the spiral open cavity 5 through the first hydraulic rod 83; The arrangement that divides the pedestal 84 into left and right parts through the arc-shaped channel 85 can prevent the first hydraulic rod 83 and the drill pipe 2 from interfering with the pedestal 84 during movement; The main function of the pedestal 84 is to position the drill pipe 2. There are multiple pedestals 84 and they are spirally arranged on the bottom end cover 3. The number of pedestals 84 is the same as the storage upper limit number of the drill pipe 2; When the drill pipe 2 moves into place, the lower first hydraulic rod 83 shortens, and the upper first hydraulic rod 83 extends until the drill pipe 2 sits in the first cavity 841 on the pedestal 84. Changing the shape of the contact surface between the first cavity 841 and the drill pipe 2 can prevent the pedestal 84 from damaging the thread at the lower end of the drill pipe 2; After the lower chuck 6 moves the drill pipe 2 into place, the first hydraulic rod 83 shortens to the position of the arc-shaped channel 85, the drill pipe 2 sits on the pedestal 84, and the upper chuck 6 moves in the reverse direction until it moves to the initial state.

[0023] Refer to Figure 2 and Figure 3 , the chuck 6 is a conical chuck 61 provided at the upper end of the drill pipe 2, and the conical chuck 61 blocks the internal thread of the drill pipe 2.

[0024] Specifically in practical applications, according to the specific shapes of the internal thread and the rod head at the upper end of the drill pipe 2, the specific shape of the chuck 6 can be designed to be able to move stably and clamp the drill pipe 2 stably. In this embodiment, it is a conical chuck 61, and this shape can stably move the drill pipe 2. Refer to Figure 4 , Figure 5 and Figure 6 , the chuck 6 is a flared chuck 62 provided at the lower end of the drill pipe 2, and the flared chuck 62 bears the drill pipe 2.

[0025] Specifically, in practical applications, when the drill pipe 2 descends, the flared portion of the flared chuck 62 can provide guidance for the drill pipe 2, and the thickness and size of the flared chuck 62 can be set according to the actual situation to improve the adaptability.

[0026] Referring to Figure 2 and Figure 4 , the driving assembly 9 includes; A driving block 91, which is fixedly arranged on the arc-shaped slider 82; A first bearing 92, which is arranged at the center of the end cover 3; A collar 93, the driving block 91 is located inside the collar 93, the driving block 91 is slidably connected to the collar 93, and the collar 93 is connected to the first bearing 92 and rotates around the first bearing 92; A driving motor 931 is installed at one end of the collar 93 away from the first bearing 92, a first gear 932 is installed at the rotating end of the driving motor 931, and a toothed ring 933 meshing with the first gear 932 is installed on the end cover 3.

[0027] Specifically, in practical applications, when the driving motor 931 rotates, it drives the first gear 932 to rotate. The first gear 932 meshes with the toothed ring 933, and the reaction force generated by the rotation of the first gear 932 drives the driving motor 931 and the collar 93 to rotate around the first bearing 92. When the collar 93 rotates, it toggles the driving block 91 and the arc-shaped slider 82 to move. The process of the arc-shaped slider 82 sliding from the outside to the inside is the process of sliding from one end of the collar 93 to the other end.

[0028] Referring to Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 11 , the positioning assembly 10 includes; A vertical through groove 101, which is arranged on both sides of the conical chuck 6; A second hydraulic rod 102, which is fixedly connected to the end cover 3, and a positioning head 7 is fixedly installed on the second hydraulic rod 102; The vertical through groove 101 allows the positioning head 7 to pass through. The cross-section of the positioning head 7 is in a U shape and clamps the drill pipe 2, and the contact surface between the positioning head 7 and the drill pipe 2 is an arc surface.

[0029] Specifically, in practical applications, when the conical chuck 6 drives the drill pipe 2 to move to a specified position, control the second hydraulic rod 102 to extend. The extension of the second hydraulic rod 102 drives the positioning head 7 to fork the drill pipe 2, and the drill pipe 2 is in a fixed state to prevent the drill pipe 2 from tipping over.

[0030] Referring to Figures 1-10 , the spiral plate 4 is fixed on the end cover 3, there are two groups of end covers 3 and they are fixed on the main frame 1, and there are two groups of spiral open cavities 5 with opposite opening directions.

[0031] Specifically in practical applications, the main frame 1 is fixedly connected to the drill rig, and the end cover 3 is fixedly connected to the main frame 1. Two sets of spiral open cavities 5 are provided with opposite opening directions, so that the drill pipe 2 is in a stable state.

[0032] Refer to Figures 1-10 , a spiral fixing plate 11 is installed on the main frame 1. The spiral fixing plate 11 is located in the middle of the main frame 1, and the middle of the drill pipe 2 is located inside the spiral fixing plate 11.

[0033] Specifically in practical applications, since the drill pipe 2 is relatively long, in order to further improve the stability of the drill pipe, a spiral fixing plate 11 is arranged at the middle position of the main frame 1, which can effectively avoid the vibration of the drill pipe 2.

[0034] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , reinforcing rib plates 31 are provided on the end cover 3, and the reinforcing rib plates 31 can be arranged along the spiral plate 4.

[0035] Specifically in practical applications, the structural strength of the end cover 3 is enhanced by the action of the reinforcing rib plates 31.
