However, in existing automated pipeline welding technologies, the continuous rotation of the workpiece during welding presents numerous challenges to temperature monitoring and recording.

[0003] Currently, the common method is to manually measure the temperature during the welding process using a handheld thermometer and then manually record the relevant temperature data. This method has significant drawbacks: firstly, manual operation makes it difficult to guarantee the timeliness and accuracy of temperature measurements, making real-time and continuous temperature monitoring impossible; secondly, manual data recording is not only inefficient but also prone to errors, hindering subsequent analysis and traceability of welding process temperature data. More importantly, there is a lack of products on the market that can automatically record the temperature during the welding process, failing to meet the urgent need for automatic temperature monitoring and recording in automated pipeline welding.

[0018] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] Please refer to Figures 1 to 4 As shown, an embodiment of this utility model provides an automatic pipe welding temperature monitoring and recording device, including: a mounting base 1, a recorder body 2 for recording the temperature of the welding pipe is mounted on one side of the top of the mounting base 1, a power supply battery 3 for powering the recorder body 2 is mounted on the other side of the top of the mounting base 1, and a fixing fixture 4 for fixing the mounting base 1 to the pipe is mounted on the top of the mounting base 1.

[0020] By adopting the above technical solution, the main body 2 of the recorder and the power supply battery 3 are integrated on the mounting base 1 and fixed to the pipeline using the fixing fixture 4, making the whole device compact, easy to install and use, and able to rotate synchronously with the pipeline to realize real-time monitoring and recording of the welding process temperature.

[0021] In order to achieve real-time monitoring of the temperature at the pipe welding location, in this embodiment: a connecting wire 201 is installed on the side of the recorder body 2, and the other end of the connecting wire 201 is connected to a thermocouple 2011 for pipe temperature monitoring. The thermocouple 2011 is connected to the recorder body 2 through the connecting wire 201, which can accurately sense the temperature change at the pipe welding location and transmit the temperature signal to the recorder body 2, providing accurate data support for subsequent temperature recording and analysis.

[0022] To securely fix the device to the pipeline, in this embodiment: the fixing fixture 4 includes an arc-shaped fixing plate 401. Two symmetrically arranged fixing straps 4011 are fixedly connected to one side of the arc-shaped fixing plate 401. On the other side of the arc-shaped fixing plate 401, and corresponding to the positions of the two fixing straps 4011, positioning components 4012 for positioning the fixing straps 4011 are installed. The shape of the arc-shaped fixing plate 401 is adapted to the outer wall of the pipeline, which can better fit the pipeline surface. The two symmetrically arranged fixing straps 4011, together with the positioning components 4012, can fix the arc-shaped fixing plate 401 from multiple directions, enhancing the stability and reliability of the fixation, and ensuring that the device will not loosen or fall off during pipeline rotation.

[0023] To achieve precise positioning of the fixing strap 4011, in this embodiment: the positioning component 4012 includes a positioning frame 402 fixedly connected to the side of the arc-shaped fixing plate 401. The positioning frame 402 is movably provided with a positioning clamping plate 4021 for positioning and clamping the fixing strap 4011. The positioning frame 402 provides installation space and movement track for the positioning clamping plate 4021. The positioning clamping plate 4021 can move within the positioning frame 402, thereby clamping and positioning the fixing strap 4011. The structure is simple and easy to operate, and the fixing strap 4011 can be quickly fixed.

[0024] To drive the positioning clamp 4021 to move, in this embodiment: a threaded sleeve 403 is fixedly connected to the side of the positioning frame 402, and a clamping screw 4031 for driving the positioning clamp 4021 is threadedly connected to the threaded sleeve 403. The end of the clamping screw 4031 is rotatably connected to the side of the positioning clamp 4021 through a bearing. By rotating the clamping screw 4031, under the action of the thread of the threaded sleeve 403, the clamping screw 4031 can move axially, thereby driving the positioning clamp 4021 to move, realizing the clamping or loosening of the fixing band 4011. This threaded driving method has a self-locking function, which can ensure that the positioning clamp 4021 will not loosen after clamping the fixing band 4011, thus improving the firmness of the fixation.

[0025] To enhance the clamping effect on the fixing strap 4011, in this embodiment, a clamping pad 404 is provided on the side of the inner wall of the positioning frame 402 and at the position corresponding to the positioning clamping plate 4021. The clamping pad 404 is usually made of a material with high friction and a certain elasticity. When the positioning clamping plate 4021 clamps the fixing strap 4011, the clamping pad 404 can increase the friction between the fixing strap 4011 and prevent the fixing strap 4011 from sliding. At the same time, it can also play a buffering role to avoid damage to the fixing strap 4011.

[0026] In order to protect the pipe surface, in this embodiment, a protective pad 405 is provided on the inner wall of the arc-shaped fixing plate 401. The protective pad 405 can prevent the arc-shaped fixing plate 401 from directly contacting the pipe surface, reduce wear and scratches on the pipe surface, and at the same time play a certain buffering role, reducing the impact force on the pipe during installation and use, and protecting the integrity of the pipe. Among them, the thermocouple 2011 can be the armored K-type thermocouple of model WRN-624, which has a high cost performance and is suitable for batch applications of automatic pipe welding. Among them, the main body 2 of the recorder can be the Fengkong FK-R1200 recorder, which supports K-type thermocouple input, 8 channels (redundant support for multi-weld point monitoring), sampling period of 1 second (to meet the real-time recording requirements of welding temperature, ≥1 time / second), working temperature 0-50℃, protection level IP54 (splash-proof), suitable for the complex environment of pipeline welding site.

[0027] In use, the main body 2 of the recorder and the power supply battery 3 are integrated on the mounting base 1. The entire device is fixed to the pipe wall to be welded using the fixing fixture 4, so that the device can rotate synchronously with the pipe, thereby recording the interpass temperature and preheating temperature of the weld joint.

[0028] In specific operation, first, the arc-shaped fixing plate 401 is placed against the outer wall of the pipe. Then, the fixing strap 4011 is passed around the bottom of the pipe and through the positioning frame 402 on the other side of the arc-shaped fixing plate 401. Next, the clamping screw 4031 is rotated. Under the action of the threaded sleeve 403, the positioning clamp 4021 is driven to position and clamp the fixing strap 4011, thus conveniently installing the arc-shaped fixing plate 401 onto the pipe to be welded. Finally, the thermocouple 2011 is fixed to the part of the pipe to be welded using high-temperature resistant fixing components such as cable ties. The thermocouple 2011 can monitor the temperature of the welding position in real time, and as the welding pipe rotates, the thermocouple 2011 can rotate accordingly, realizing automatic temperature monitoring. At the same time, the recorder body 2 records the temperature data in real time.
