1、Main structure and working principle
Structural composition
Cutting blade: This is the core component, usually made of high-strength alloy steel. The thickness, diameter and number of teeth of the blade will vary according to the cutting object. For example, when cutting thick reinforced concrete floor slabs, thicker blades with larger diameters and more teeth are required to ensure the efficiency and quality of cutting.
Transmission system: It is mainly responsible for transmitting the power of the power device to the cutting blade to make it rotate at high speed. The transmission system includes components such as belts and gears, which require high transmission efficiency and stability to ensure that the cutting blade can cut at a suitable speed.
Travel mechanism: It is convenient for the operator to push the cutting machine to move on the surface of the floor slab for straight or curved cutting. The walking mechanism usually has wheels or track guide devices, and some advanced models can also realize automatic walking function to improve the accuracy and efficiency of cutting.
Working principle
When the power device is started, the cutting blade is driven to rotate at high speed through the transmission system. When the rotating blade contacts the surface of the floor, it uses the sharp edge of the blade and the cutting force generated by the high-speed rotation to gradually cut the floor material. During the cutting process, the operator controls the cutting path of the cutting machine through the walking mechanism and completes the cutting operation of the floor according to the predetermined size and shape.
2、Application scenario
Building demolition project
During the demolition of old buildings, part of the floor structure needs to be removed. The floor cutting machine can accurately cut out the floor area that needs to be demolished to avoid unnecessary damage to the surrounding structure. For example, in the renovation project of old buildings in the city center, for some situations where the building facade needs to be retained and the internal floor is demolished, the floor cutting machine can efficiently complete the cutting task while ensuring safety.
Renovation and expansion in building construction
When a building needs to be functionally transformed or expanded, it may be necessary to open a hole in the original floor for the installation of facilities such as stairs, elevators or ventilation ducts. The floor cutting machine can accurately cut out holes that meet the size requirements, and the edges after cutting are neat, which is conducive to subsequent construction. For example, in the renovation project of the shopping mall, in order to install a new escalator, a floor cutting machine can be used to cut a suitable opening on the floor.
3、Operation precautions
Safety protection
Operators must wear complete safety protection equipment, including hard hats, goggles, earplugs, protective gloves and work clothes. Goggles can prevent debris generated during the cutting process from splashing into the eyes; earplugs can reduce noise damage to hearing; protective gloves protect hands from injury.
Preparation before cutting
Check whether all parts of the equipment are normal, especially whether the cutting blade is firmly installed and whether the power unit can start and run normally. At the same time, it is necessary to clean the cutting area, remove debris and obstacles on the surface of the floor, and ensure a smooth cutting process.
Cutting process operation
During the cutting process, keep the cutting speed uniform and avoid too fast or too slow. Too fast cutting speed may cause increased blade wear and uneven cutting surface; too slow will affect work efficiency. Also, pay attention to the cutting conditions. If you find that the blade is shaking abnormally or the cutting resistance is too large, stop cutting immediately, check the cause and deal with it.
