Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] This embodiment provides an auxiliary anode sheath removal device, which is mainly used to take out the anode sheath 10 installed on the flange 7 . Such as figure 1 As shown, the anode sheath 10 is a T-shaped cylindrical structure, and is installed on the flange 7 through the sealant 8, and the flange 7 is installed at the opening of the protected pipeline 9.

[0031] The structure of the auxiliary anode sheath removal device in this embodiment is as follows: figure 2 As shown, it includes a push rod 1, a main body 2 and a bracket 3.

[0032] The push rod 1 has a T-shaped structure and includes an upper handle and a vertical rod body. The upper handle is used for pulling or pressing down the push rod 1. The rod body can be a long cylindrical rod.

[0033] The main body 2 is a T-shaped structure, including an upper handle an...

Abstract

The invention belongs to the technical field of special clamps, and particularly relates to an auxiliary anode sheath taking-out device and a using method thereof. According to the auxiliary anode sheath taking-out device and the using method thereof, a main auxiliary anode sheath is clamped by a movable expansion clamping hook, then the whole device is fixed by a bracket, and the auxiliary anodesheath is taken out by rotating a T-shaped main body. The auxiliary anode sheath taking-out device has the advantages that (1) the use of the bracket enables the whole device to be stable, and the stress of the auxiliary anode sheath can be controllable; (2) the T-shaped main body is slightly thinner than the anode sheath, the anode sheath can be supported to a certain extent, and the sheath is prevented from breaking; and (3) a customized bearing enables the T-shaped main body to rotate independently, so that the reliability of a buckle between the movable expansion clamping hook and the anode sheath is not affected.

Description

technical field [0001] The invention belongs to the technical field of special clamps, and in particular relates to an auxiliary anode sheath removal device and a use method thereof. Background technique [0002] In the seawater system of nuclear power plants, in order to protect some important pipelines, some auxiliary anodes are usually arranged in the pipelines. Such as figure 1 As shown, in order to ensure the tightness, the auxiliary anode sheath is bonded to the flange by sealant, then the gasket is placed, the auxiliary anode is inserted, and the auxiliary anode is fixed on the pipeline by tightening the flange bolts. [0003] During actual use, some auxiliary anodes may be broken, damaged or leaked, so they need to be checked and replaced regularly. However, due to long-term service, the sealant reacts with the anode sheath and the flange surface, causing the anode sheath and the flange to be firmly combined and difficult to remove. Existing removal methods are of...
