[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] Embodiment An environmentally friendly rotary control device assembly pick-up and delivery device

[0030] like Figure 1 As shown, this embodiment includes a pick-up and delivery rod 1, two suspension rods 2 that can be retracted laterally and are arranged at the lower part of the pick-up and delivery rod 1, a camera mechanism 3 installed on the pick-up and delivery rod 1 and located above the two suspension rods 2, a connector 4 for installing the pick-up and delivery rod 1 at the lower end of the drill pipe, and an operating table 5. The two suspension rods 2 are symmetrical about the longitudinal axis of the pick-up and delivery rod 1; the farthest distance between the two ends of the two suspension rods 2 in the retracted state is less than the spacing between the two suspension rings on the rotating assembly. The operating table 5 is provided with a display screen for displaying the real-time shooting results of the camera mechanism 3, and a control mechanism for the suspension rod 2. The control mechanism is connected to the two suspension rods 2 respectively through control pipelines, and the signal input end of the display screen is connected to the signal output end of the camera mechanism 3 through a signal line.

[0031] like Figure 1 As shown, in order to prevent accidents such as falling during the process of picking up and delivering the rotating assembly, the suspension rod 2 is further configured as an L-shaped rod in this embodiment, and its transverse support rod is a hydraulic telescopic rod. The control pipeline is a hydraulic control pipeline, and the control system is a hydraulic control system. The hydraulic control system includes a hydraulic control pump and a pump pressure monitor for detecting the pump pressure. The control pump is connected to the hydraulic telescopic rod through the control pipeline.

[0032] Furthermore, a wiring channel for hydraulic control lines and signal lines is provided in the taking and delivering rod 1 , and a connector 6 for connecting the hydraulic control lines and the signal lines of the camera mechanism 3 is provided at the top of the taking and delivering rod 1 .

[0033] Since the external thread types of the lower ends of different drill pipes are different during drilling construction, this embodiment uses the following method to match different drill pipes: Figure 2 The reducer nipple shown is used as a connector 4 for connecting the delivery rod 1 and the drill pipe. The upper portion of the reducer nipple is provided with a first internal thread that is compatible with the external thread at the lower end of the drill pipe, the lower portion of the reducer nipple is provided with a first external thread, and the upper end of the delivery rod 1 is provided with a second internal thread that is compatible with the first external thread. On different reducer nipple pipes, the model of the first internal thread is different, and the model of the first external thread is the same. Before the delivery operation, it is first necessary to select a compatible reducer nipple according to the model of the external thread at the lower end of the drill pipe. The adaptation here means that the drill pipe can be threadedly connected with the first internal thread at the upper portion of the reducer nipple through the external thread at its bottom end, and the reducer nipple can be threadedly connected with the second internal thread at the upper end of the delivery rod 1 through the first external thread provided at its lower portion.

[0034] During the picking and delivering process, the lower end of the picking and delivering rod 1 needs to extend into the housing. In order to prevent the lower end of the picking and delivering rod 1 from touching the housing and causing damage, a guide cone 7 is fixedly provided at the bottom end of the picking and delivering rod 1 in this embodiment.

[0035] Usage method: First, select a corresponding reducer nipple according to the model of the external thread at the lower end of the drill pipe; then connect the drill pipe to the take-up and delivery rod 1 through the reducer nipple, and then connect the hydraulic control pipeline and signal line led out of the operating table 5 to the joint 6 at the top of the take-up and delivery rod 1 respectively; after completing the above connection operation, start this embodiment, the No. 1 operator located on the drilling platform operates the drilling rig, and the take-up and delivery rod 1 is gradually lowered by the drill pipe, and the No. 2 operator observes the position of the hanging rod 2 in real time through the display screen, and notifies the No. 1 operator to stop lowering the take-up and delivery rod 1 when the hanging rod 2 reaches the appropriate position, and rotates the drill pipe to drive the take-up and delivery rod 1 to rotate until the two hanging rods 2 are aligned with the two lifting rings of the rotating assembly, the No. 1 operator stops the operation, and the No. 2 operator controls the two hydraulic telescopic rods through the hydraulic control system to extend into the two lifting rings accordingly, and finally notifies the No. 1 operator to operate the drilling rig, and the drill pipe drives the take-up and delivery rod 1 to lift the rotating assembly upward until the rotating assembly is taken out. The process of placing the rotating assembly into the shell is the opposite of the process of taking out the rotating assembly: the rotating assembly is hung on the pick-up and delivery rod 1, and operator No. 1 operates the drilling rig to make the drill rod drive the pick-up and delivery rod 1. After the pick-up and delivery rod 1 is sent into the shell and the rotating assembly is placed, operator No. 2 controls the two hydraulic telescopic rods to retract through the hydraulic control system, and finally notifies operator No. 1 to operate the drilling rig to lift the drill rod, driving the pick-up and delivery rod 1 to lift upward.

[0036] In this embodiment, the connecting member 4 may also be a flange.
