[0023] The driving assembly 4 includes a rotating rod 41 and a driving motor. One end of the rotating rod 41 passes through the middle side wall of the fixed connection supporting foot plate 5. The rotating rod 41 is rotatably mounted on the mounting frame 2. The driving motor is fixedly mounted on the mounting frame 2. The output end of the driving motor is transmission-connected to the outer side wall of the rotating rod 41. The output end of the driving motor and the rotating rod 41 are transmission-connected through a transmission wheel and a transmission belt. The supporting foot plate 5 is driven to rotate in the annular guide rail 3 by driving the rotating rod 41 to rotate.

[0024] like Figure 3 and Figure 4 In the embodiment, the movable support rod 6 includes a fixed base 61 fixedly mounted on the supporting foot plate 5, the top end of the fixed base 61 is rotatably connected to a guide column 62, the outer side wall of the guide column 62 is slidably sleeved with a guide slide 63, a limited sliding structure is provided between the guide column 62 and the guide slide 63, the top end of the guide slide 63 is fixedly connected to the open plug 52, and the open plug 52 is bent at the top end of the fixed base 61 under the action of the rotation drive mechanism 7, thereby realizing the rotation of the open plug 52, and the horizontally placed open plug 52 and the pipe fitting can be adjusted to a vertical state, and the pipe fitting can be delivered to the bottom of the drilling rig head 1; the limited sliding structure includes a fixed connection The limiting slider 65 on the guide column 62 and the limiting slide groove 64 are provided on the guide slide 63, and the limiting slider 65 is slidably connected in the limiting slider 65 to limit the sliding distance of the guide slide 63 on the guide column 62 to prevent the guide slide 63 from slipping off the guide column 62; a return spring 66 is fixedly connected between the fixed base 61 and the outer wall of the guide slide 63, and a corner limit plate 67 is fixedly connected to the outer wall of the fixed base 61, and the corner limit plate 67 is used to limit the rotation angle of the guide slide 63 and the guide column 62 on the fixed base 61, and the return spring 66 can apply a driving force to the guide slide 63 in the direction of the fixed base 61 through its own elasticity, thereby assisting the guide slide 63 in resetting.

[0025] like Figure 3 and Figure 5 In the embodiment, the rotary drive mechanism 7 includes an electric telescopic rod 71 and a receiving plate 72. The electric telescopic rod 71 is rotatably mounted on the mounting frame 2, and the receiving plate 72 is fixedly connected to the mounting frame 2. Figure 4In the embodiment, the docking member includes a T-shaped slider 8 and a T-shaped guide rail 81. The T-shaped slider 8 is provided with several T-shaped sliders 8. The T-shaped sliders 8 are all fixed to the side of the opening insert 52 close to the drill head 1. The T-shaped guide rail 81 is rotatably connected to the output end of the electric telescopic rod 71. The T-shaped slider 8 can slide to the inside of the T-shaped guide rail 81 to complete the card connection. When the rotating rod 41 drives the opening insert 52 to rotate through the supporting foot plate 5, the T-shaped slider 8 is synchronously driven to rotate, which can drive the T-shaped slider 8 to slide on the T-shaped guide rail 81 to complete the card connection. In the operation and separation action, at the output end of the electric telescopic rod 71, the T-shaped slider 8 and the T-shaped guide rail 81 pull the open insert 52 to drive the guide slide 63 to bend at the top of the fixed base 61, and the guide slide 63 contacts the receiving plate 73. Since the guide slide 63 is slidably sleeved on the guide column 62, the T-shaped guide rail 81 is continuously pushed by the output end of the electric telescopic rod 71.

[0026] like Figure 1 and Figure 2 In the embodiment, a semi-annular guide rail 31 is further provided between the two annular guide rails 3, and the semi-annular guide rail 31 is installed on the mounting frame 2. A plurality of rollers 32 are provided on the inner side walls of the annular guide rail 3 and the semi-annular guide rail 31. When the pipe fitting is carried in the open insert 52 and rotates with the support foot plate 5, the pipe fitting can slide close to the inner side walls of the annular guide rail 3 and the semi-annular guide rail 31. The annular guide rail 3 and the semi-annular guide rail 31, together with the fixed support rod 51 and the open insert 52, limit the pipe fitting together, and stably confine the pipe fitting in the open insert 52. The setting of the roller 32 causes the outer wall of the pipe fitting to roll with the annular guide rail 3 and the roller 32, reducing wear, thereby reducing the driving force required for the rotation of the support foot plate 5.

[0027] Reinforcing rods 33 are fixedly installed on the top of the annular guide rail 3 between the two sides of the loading window and the mounting frame 2 to strengthen the structural stability of the annular guide rail 3; the outer wall of one end of the opening insert 52 is placed on the top of the fixed support rod 51, and the fixed support rod 51 is provided with a baffle 9 on the side away from the movable support rod 6. The baffle 9 is installed on the mounting frame 2, and the side wall of the baffle 9 is fixedly installed with a mounting insert 91.

[0028] In this embodiment, the prepared pipe fittings can be inserted into the tray and the open pipe fittings 52 in the annular guide rail 3 through the installation insert 91. Under the driving action of the drive assembly 4, different open pipe fittings 52 are switched to align with the installation insert 91, and multiple pipe fittings can be inserted continuously. When the prepared pipe fitting needs to be installed on the drilling rig head 1, the driving assembly 4 drives the supporting foot plate 5 to rotate, so that the open insert 52 moves with the supporting foot plate 5 and the movable support rod 6 to the notch of the annular guide rail 3, that is, the top position of the annular guide rail 3. Since the T-shaped slider 8 is naturally engaged in the T-shaped guide rail 81, the electric telescopic rod 71 is started to extend, and the open insert 52, the guide column 62 and the guide slide 63 can be driven to rotate on the top of the fixed base 61 through the T-shaped guide rail 81 and the T-shaped slider 8 under the action of the extended force arm 82, thereby driving the open insert 52 and The internal pipe is rotated ninety degrees, and the receiving plate 72 provides support for the guide slide 63, so that the pipe is upright. The electric telescopic rod 71 is further extended, and the guide slide 63 can be pulled to slide on the outer wall of the guide column 62, thereby extending the length of the movable support rod 6. The open insert 52 and the upright pipe can be further delivered to the bottom of the drilling rig head 1. The extension and extension of the movable support rod 6 can be controlled to further adjust the position of the pipe to further align it with the position of the drilling rig head 1, thereby facilitating the installation of the pipe. Thereby, there is no need to use external lifting equipment to complete the work of installing the pipe, saving resources. After the drill rig head 1 is docked with the pipe fitting, the drill rig head 1 can be moved up on the drill rig boom to pull the pipe fitting out of the bottom of the opening plug cylinder 52, and the electric telescopic rod 71 can be started to retract. The electric telescopic rod 71 will drive the T-shaped guide rail 81 to rotate and reset. At the same time, the return spring 66 will contract under its own elastic action, pulling the guide slide 63 to reset on the guide column 62. Under the joint action of the electric telescopic rod 71 and the return spring 66, the movable support rod 6 is driven to retract and reset, and the opening plug cylinder 52 and the T-shaped guide rail 81 are driven to rotate and reset. At this time, the driving component 4 can be used to drive the support foot plate 5 to rotate to switch the ready-to-install pipe fitting located at the opening position of the annular guide rail 3, or the open plug cylinder 52 aligned with the installation plug cylinder 91 can be switched to increase the ready-to-install pipe fitting.

[0029] As described above, in the present invention, the annular guide rail, the drive assembly, the support foot plate and the movable support rod are used in conjunction with each other, and a plurality of drill pipe fittings can be prepared. When installing the drill pipe fittings, the corresponding drill pipe is transferred to the loading window, and the movable support rod is used in conjunction with the rotary drive mechanism to make the drill pipe stand upright and push it to the bottom of the drilling rig head for installation. The operation is simple, no external lifting equipment is required, and resources are saved. It can reasonably utilize the horizontal space resources; it can add the key for preparatory installation into the annular guide rail during the operation of the drilling rig and the installation of the pipe, saving time, and can prepare multiple drill pipes and fittings at the same time, thereby improving the operating efficiency of the engineering drilling rig.
