[0001] The invention relates to the technical field of steel structure cutting, in particular to a steel structure cutting device. Background Art
[0002] During the use of steel structures, they need to be cut according to the needs so that they meet the use requirements. Existing steel structures have various shapes, such as channel steel, I-beam, steel plate, etc. When cutting steel structures, it is generally necessary to fix the steel structures to prevent the steel structures from shifting during cutting, which leads to inaccurate cutting positions. The existing steel structure cutting device still has the following technical problems when in use, such as: 1. The existing steel structure cutting device generally fixes the steel structure manually, that is, the staff presses the steel structure with their hands. However, when operating in this way, the staff's hands are easily moved due to the vibration generated by the cutting, which leads to the position of the steel structure being offset, making the cutting position inaccurate. In addition, this method is not safe enough and is prone to safety accidents; 2. The existing steel structure cutting device cannot fix channel steel, I-beam or other shaped steel structures, so that the existing steel structure cutting device cannot stably and accurately cut channel steel, I-beam or other shaped steel structures; Therefore, a steel structure cutting device is needed to solve the above problems.
