Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure manifold processing, and particularly relates to a boring device for high-pressure manifold processing. Background Technique

[0002] The high-pressure manifold is an important drilling device and a key part connecting the main pipeline and the high-pressure pump. Therefore, its connection method is also one of the key links in drilling operations. It includes swivel elbows, plug valves, integral straight pipelines, integral joints, safety valves, check valves, throttle valves, annular manifolds, and drum rotary joints, etc., with a maximum pressure of up to 20,000 psi. Among them, the swivel elbow is the single product with the largest usage quantity.

[0003] During the production, processing, and later maintenance of high-pressure manifolds, a boring device for high-pressure manifold processing is used to bore the high-pressure manifold. The boring device for high-pressure manifold processing is a device specifically used for the repair and processing of the inner holes of large pipelines, with powerful processing capabilities and a high-strength boring bar. During the manufacturing and maintenance of high-pressure manifolds, the boring device plays a crucial role. This device can precisely process the holes inside the manifold to ensure that it meets the requirements in high-pressure environments such as oil and gas drilling.

[0004] Common high-pressure manifolds are relatively large in volume and long in pipeline length. During processing, one end is clamped by a fixture, and the manifold needs to be supported on one side of the boring to prevent the manifold from shifting during the processing. However, common manifold support structures directly support on the outer wall of the pipeline, and the outer surface of the pipeline is relatively smooth, so there is still a risk of shifting during the processing. In view of this, this application proposes a boring device for high-pressure manifold processing. Content of the Utility Model

Two limiting ring plates are fixedly installed on the surface of the half sleeve. Connecting plates are fixedly installed on the opposite sides of the two half sleeves, and the two connecting plates are bolted and nut-connected through bolts and nuts.

[0008] Furthermore, the support assembly includes four fixing nuts fixedly installed on the outside of the movable support ring. Adjusting screws are threadedly installed inside the fixing nuts.

The width of the support guide wheel is equal to the distance between the two limiting ring plates.

[0009] Furthermore, a movable screw threadedly connected to the movable support slider is rotatably installed on the inner side wall of the moving groove. A moving motor with an output shaft fixedly connected to one end of the movable screw is fixedly installed on one side of the installation base.
