[0032] The working principle of the embodiment is as follows: in use, the preheating device is moved by rotating the universal wheel 25, so that the preheating device can move flexibly in the working site, facilitating the adjustment of the position according to the construction requirements. By rotating the handle two 29, the handle two 29 drives the screw rod 27 to rotate in the block 26, so that the screw rod 27 pushes the foot 28 to move downward and contact with the ground, achieving the purpose of fixing the preheating device, so that it remains stable in the working state. At the same time, the four corners of the preheating device can be leveled according to the flatness of the bottom surface, so as to improve the convenience of work. Then, the other three groups of feet 28 are operated according to the above operation steps. By placing one end of the steel structure plate super-thick plate to be welded between the placing groove one 31 and the placing groove two 32 between the lower heating plate 3 and the upper heating plate 4, the cross section of the super-thick plate to be welded is heated, achieving the purpose of heating the middle part of the cross section of the two super-thick plates, thereby improving the subsequent welding quality and reducing the possibility of welding defects.

The anti-skid pad 19 on the clamping plate 18 can further increase the stability of the two groups of clamping plates 18 clamping the super-thick plate. The handle sleeve 21 can improve the comfort of holding the handle one 20 when rotating the handle one 20, and can also avoid the direct contact between the palm and the handle one 20 to produce friction and cause hand discomfort. By pressing the pressure rod one 11 and the pressure rod two 12, the plug one 8 and the plug two 10 can move towards each other and press the spring 9. Then, the upper heating plate 4 is lifted, the plug one 8 and the plug two 10 are separated from the clamping groove 15, so that the disassembly and assembly work between the upper heating plate 4 and the lower heating plate 3 becomes simple and fast, improving the working efficiency of the disassembly and assembly work between the upper heating plate 4 and the lower heating plate 3. Through the clamping mechanism, the work of clamping and fixing the super-thick plate is realized, avoiding the shaking of the super-thick plate due to accidental collision of the preheating device, so as to avoid affecting the preheating work of the super-thick plate cross section to be welded by the upper heating plate 4 and the lower heating plate 3. Through the cooperation of the guide rod 23 and the guide hole 22, the movement of the clamping plate 18 can be guided and limited, avoiding rotation during movement to avoid affecting the use. By inserting the limiting rod 13 on the upper heating plate 4 into the limiting block 14 on the lower heating plate 3, the upper heating plate 4 can be limited, so as to avoid sliding of the upper heating plate 4 due to vibration or inertia during movement of the preheating device, further improving the stability of the connection between the upper heating plate 4 and the lower heating plate 3.

[0033] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
