Redundant object clearing device and method for inner surface of curved guide pipe

Abstract

The invention provides a redundant object clearing device and method for an inner surface of a curved guide pipe. The clearing device comprises a nozzle (100), a rigid hose (200), a sealing hose (300)and a connector (500), wherein one end of the sealing hose (300) is connected with the nozzle (100), the other end of the sealing hose (300) is connected with the connector (500), the rigid hose (200) is arranged outside the sealing hose (300), and the connector (500) is used for allowing high-pressure water or airflows to be guided in. By adopting the clearing device, redundant objects on the inner surface of the curved guide pipe (600) can be thoroughly cleared through three steps of cleaning through water flows, blowing down through the airflows and drying. The clearing device is simple instructure and convenient in installation, and can quickly and accurately clear the redundant objects in the curved guide pipe (600) in a mode that the high-pressure water flows and the airflows are sprayed sequentially.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a device and method for cleaning excess material on the inner surface of a curved conduit. Background technique [0002] Catheter products are widely used in important components in aerospace, shipbuilding, automobiles, machinery and other fields. The conduits that communicate with important components such as engines have strict requirements on the control of excess in the conduits. Any tiny residual metal shavings, residual acid and lye, etc. may have a serious impact on the normal operation of the entire product. Existing catheter products are often complex in shape, and some catheters have small diameters, which pose a great challenge to the cleaning of redundant materials inside the catheter. The current mechanical cleaning devices are often suitable for large-diameter catheters, but not suitable for small-diameter catheters. Appropriate cleaning methods for small-di...

Problems solved by technology

[0003] Patent document CN109108004A discloses a device for cleaning impurities on the inner wall of oil pipelines, which includes a base, a bracket for installing oil pipelines at one end of the base, and a cleaning mechanism that moves along the length of the oil pipeline at the other end of the base. The cleaning includes a sliding base, which slides freely on the base, and a shaft extending into the oil pipeline is arranged on the sliding base, one end of the shaft is pivotally connected with the sliding base through a bearing seat, and the other end of the shaft is provided with a Abrasive tool for cleaning oil pipelines. The outer circle of the abrasive tool is equipped with multiple grinding discs. The multiple grinding discs are attached to the inner wall of the oil pipeline. There is a driving mechanism at one end of the shaft to drive the rotation of the shaft. The mechanism is used to drive the shaft to rotate, and the abrasive tool is concentric with the oil pipeline, but this device cannot clean the inner wall of the curved pipeline
