Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a high-frequency straight seam welded pipe welding temperature monitoring and alarm device. Background Technology

[0002] In the high-frequency induction welding process of straight seam welded pipes, the welding temperature is controlled solely by the operator observing the color of the heating material at the V-shaped opening and adjusting the current and voltage output of the high-frequency power supply. Therefore, the quality of the weld seam in high-frequency welded pipes cannot be guaranteed. Consequently, some welding temperature monitoring and alarm devices have emerged. However, these devices are fixed in location and cannot be adjusted according to actual needs. The entire device must be disassembled, repositioned, and then reinstalled, which is extremely inconvenient. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a high-frequency straight seam welded pipe welding temperature monitoring and alarm device, comprising two symmetrically arranged risers. A base is installed at the bottom of each riser, and an adjusting vertical rod is inserted into the top of each riser. The adjusting vertical rod is fixed inside the riser by a locking assembly. The tops of the two adjusting vertical rods are connected by a horizontal rod. An mounting component is sleeved on the horizontal rod and fixed to the horizontal rod by the locking assembly. An infrared thermometer is installed at the bottom of the mounting component, with its bottom vertically pointing downwards towards the welding position of the steel pipe. The infrared thermometer is electrically connected to a control component on one side of each riser via a cable. An alarm is installed on the horizontal rod and is electrically connected to the control component via a cable.

[0006] Furthermore, the bottom surface of the base is provided with an anti-slip layer.

[0007] Furthermore, a limiting ring is fitted onto the crossbar, and the cable passes through the limiting ring.

[0008] Furthermore, the control assembly includes a support frame and a touchscreen controller mounted on top of the support frame, with the infrared thermometer and alarm both connected to the touchscreen controller via the cable.

[0009] Furthermore, the locking assembly includes a set screw threaded onto the riser and the mounting component, and both the adjusting vertical rod and the horizontal rod have top grooves, with the bottom of the set screw resting on the top groove.

[0010] Furthermore, both the adjusting vertical rod and the horizontal rod are equipped with scale bars.

[0011] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0012] This invention directly monitors the temperature change at the welding point using an infrared thermometer, and generates a curve graph through a touch screen controller. It can monitor the temperature at any time and directly alarm when the temperature is not up to standard. It can also adjust the position of the infrared thermometer according to actual needs to meet different production environments. Attached Figure Description
