[0017] The present application also provides a technical solution, a method for using a low-volatility heat tracing pipe replacement auxiliary tool, the specific steps are as follows:

[0018] S1, rotate the first hinged member, adjust the position of the first hinged member under the restriction of the rotating groove formed on the surface of the mounting ring through the sliding block, the limiting hook contacts the inclined side of the gear ring during the rotation of the first hinged member, the limiting hook is lifted by the gear ring to release the limitation, the first hinged member can rotate normally, after reaching the specified position, the limiting hook is embedded in the tooth groove of the gear ring, and the position of the first hinged member is limited to a certain extent;

[0019] S2, rotate the first connecting rod, rotate the first connecting rod under the restriction of the first hinged member and perpendicular to the heat tracing pipe body, then rotate the second connecting rod, rotate the second connecting rod under the restriction of the second hinged member and drive the sleeve groove to the position on both sides of the heat tracing pipe body, and the inner wall of the sleeve groove is attached to the heat tracing pipe body.

[0020] S3, rotate the sleeve, rotate the sleeve under the restriction of the sleeve groove and move out from the inside of the sleeve groove, the sleeve groove cooperates with the sleeve to form a circle that is sleeved on the surface of the heat tracing pipe body, after the sleeve is rotated to the appropriate position, the first adjusting groove pushes the plug out from the inside of the spring groove and inserts it into the plug groove, and the plug cooperates with the plug groove to limit the position of the sleeve.

[0021] S4. Pull the pull rod so that the pull rod drives the third connecting rods on both sides to move through the connector. The third connecting rod pulls the second connecting rod through the rotating shaft so that the second connecting rod pulls the two ends of the heat tracing pipe body through the collar groove and collar. The two ends of the heat tracing pipe body gradually lift up and move out from the restriction of the heat tracing pipe clamp. The heat tracing pipe body is removed.

[0022] S5. During the process of pulling the connecting part outward, the connecting part drives the telescopic rod to move under the restriction of the telescopic groove and the guide rod, and squeezes the second spring to produce elastic deformation. After the heat tracing pipe body is removed, the pull rod is released, the elastic deformation of the second spring is restored and pushes the telescopic rod to move, so that the connecting part is reset under the movement of the telescopic rod, avoiding continuous bending of the heat tracing pipe body.

[0023] S6. After the heat tracing pipe body on one side is removed, release the restriction of the collar groove and collar on the heat tracing pipe body, and then take out the heat tracing pipe body. Then rotate the first connecting rod and the first hinge to rotate the first connecting rod and the first hinge to the other side of the regulating valve, and carry out the removal operation of the heat tracing pipe body on the other side.

[0024] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0025] 1. By incorporating the installation ring, first hinge, and mounting mechanism, the system effectively avoids the problem of pipe rupture caused by excessive stress or strain on the other side due to the tight connection between the two sides of the heat tracing pipe during disassembly if only one side of the heat tracing pipe is removed. The system rotates the first hinge to a designated position, then rotates the first connecting rod to rotate under the constraint of the first hinge and perpendicular to the heat tracing pipe body. Next, the second connecting rod rotates under the constraint of the second hinge and connects to the heat tracing pipe body through the mounting mechanism. After releasing the connection at both ends of the heat tracing pipe body, the second connecting rods on both sides are simultaneously pulled, causing them to move through the mounting mechanism to release the connection with the heat tracing pipe clamp. Both sides of the heat tracing pipe body are simultaneously removed from the regulating valve, improving the safety of the device.

[0026] 2. Through the designed pulling and resetting mechanisms, workers can pull the pull rod, which, via the connecting piece, moves the third connecting rods on both sides. The third connecting rods, via the rotating shaft, move the second connecting rod, causing the second connecting rod to pull both ends of the heat tracing pipe body through the collar groove and collar. The ends of the heat tracing pipe body gradually tilt upwards and move out of the constraint of the heat tracing pipe clamp, completing the removal of the heat tracing pipe body. Simultaneously, as the pull rod pulls the connecting piece outwards, the connecting piece moves the telescopic rod under the constraint of the telescopic groove and guide rod, compressing the second spring to produce elastic deformation. After the heat tracing pipe body is removed, the pull rod is released, the second spring's elastic deformation recovers, and it pushes the telescopic rod to move, allowing the connecting piece to reset under the movement of the telescopic rod. This avoids continuous bending of the heat tracing pipe body, thus achieving the purpose of pulling the pull rod to move the second connecting rods on both sides synchronously and automatically resetting through the second spring, improving the convenience of the device.
