Abstract
The invention relates to real-time temperature monitoring in a steel rail aluminothermic welding preheating operation process, in particular to a real-time temperature monitoring device based on a surface contact temperature sensor, which is used in the steel rail aluminothermic welding preheating operation process and is suitable for construction detection of railway seamless steel rail welding.The invention provides the steel rail aluminothermic welding preheating temperature monitoring device to solve the problems that in the preheating temperature judging process of existing steel rail aluminothermic welding through a visual observation method, the influence of observers, equipment and external environment is large, and the construction quality does not have traceability. Two rail head clamping bases and two rail foot clamping bases of the device clamp rail heads and rail feet of two steel rail joints to be welded respectively; inserting holes and clamping grooves which are matched with the surface contact temperature sensors are formed in the clamping bases; the surface contact temperature sensors are arranged on the rail head clamping bases or the rail foot clamping bases through the jacks; the surface contact temperature sensors are in contact with the rail heads or the rail feet; and the surface contact temperature sensors are electrically connected with a four-way digital temperature display instrument.
Description
technical field [0001] The present invention relates to the temperature real-time monitoring of the rail aluminothermic welding preheating operation process, in particular to a temperature real-time monitoring device based on a surface contact temperature sensor used in the rail aluminothermic welding preheating operation process, suitable for railway seamless rail welding construction inspection. Background technique [0002] Aluminothermic welding is a method of welding by using the superheated molten metal produced by the exothermic reaction between metal oxide and metal aluminum to melt the metal of the joint to be welded. At present, aluminothermic welding has been widely used as the main welding method for the restoration of seamless circuit structure. [0003] The preheating process of aluminothermic welding is one of the key links in the whole welding process. If the temperature and uniformity of the weld and heat-affected zone are not properly controlled, it will d...
