Detailed Implementation

[0021] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0022] An online temperature detection device for steel pipe welds includes a thermometer 4. Its innovation lies in that it also includes a main support 3, a thermometer mounting frame 5, and a laser channel 6. The main support is welded and fixed to the rolling center. The thermometer mounting frame is mounted on the main support, and the thermometer is mounted on the thermometer mounting frame. The laser channel is coaxially connected to the lower part of the thermometer.

[0023] The main support consists of a support beam 8, a support plate 9, and a suspension frame 10. The support beam is welded and fixed to the rolling center, the support plate is fixed to the support beam, and the suspension frame is fixed to the support plate. There are two support beams, which makes the connection more secure and stable. The suspension frame has positioning holes 11. There are multiple positioning holes, four in this embodiment; the positioning holes are used to adjust the position of the temperature measuring point of the temperature measuring instrument in conjunction with the fixing holes and the adjusting slide holes.

[0024] The thermometer mounting bracket consists of a horizontal plate 15 and a vertical plate 12, which are connected in an L-shape as a single unit. The vertical plate has fixing holes 13 and adjusting slide holes 14; these holes and slide holes are used to adjust the position of the thermometer's measuring point in conjunction with the positioning holes. The horizontal plate has a probe mounting sleeve 16.

[0025] The laser channel is a conical tubular body with an air inlet 20. An internal thread is formed on the upper part of its inner cavity for connection to the temperature measuring instrument. The laser channel is filled with an inert gas, typically argon. Argon is a colorless, odorless, and non-toxic gas, effectively preventing water vapor from the steel pipe production line from entering the laser channel and affecting temperature measurement accuracy.

[0026] The thermometer is a CTlaser series non-contact infrared thermometer. Its main structure consists of a transmitter 21 and a transmitter housing 22. The transmitter housing is mounted on the thermometer mounting bracket, and the transmitter is located inside the transmitter housing. The transmitter housing has a cooling water circulation channel 19 and is equipped with a water inlet 17 and a water outlet 18.

[0027] The working principle of this utility model:

[0028] When using this online steel pipe weld temperature detection device, the device is installed in the rolling center of the steel pipe production line. The fixing holes and adjusting groove holes on the vertical plate of the temperature measuring instrument mounting bracket are aligned with adjacent positioning holes as needed. The temperature measuring point of the temperature measuring instrument is adjusted to align with the weld seam of the steel pipe 1 at an appropriate position in front of the middle contact 7 of the extrusion roller 2, and then fixed with bolts. The temperature measuring instrument is electrically connected to the production line control center. The laser channel is filled with inert gas, usually argon, which is colorless, odorless, and non-toxic, effectively preventing water vapor from the steel pipe production line from entering the laser channel and affecting the temperature measurement accuracy. The water inlet and outlet on the temperature measuring instrument's transmitter jacket are connected to the cooling water source, and the circulating water pump is started. During production, the temperature measuring instrument transmits the obtained temperature data to the production line control center. The control center compares the obtained real-time temperature data with standard data and adjusts the welding current accordingly based on the deviation to obtain satisfactory weld temperature and welding effect.

[0029] When the thermometer deviates from its position for various reasons, resulting in a misalignment of the temperature measurement point, it can be adjusted and corrected using the fixing holes, adjusting slide holes, and positioning holes on the mounting bracket's vertical plate. Height deviations can be adjusted by changing the positioning holes; left-right deviations can be adjusted by adjusting the slide holes. To adjust, first slightly loosen the bolts on the fixing holes and adjusting slide holes, then rotate the thermometer and laser channel left or right according to the deviation. Once the temperature measurement point is aligned, tighten the bolts on the fixing holes and adjusting slide holes.

[0030] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
