Importance and selection standard of door lock for stone drilling equipment protection door
In the stone processing industry, safety is always an important link that cannot be ignored. As a part of it, it is particularly important to set the protective door lock of stone drilling equipment, which is not only related to the stability and safety of the equipment itself, but also to the life and property safety of operators.
I. What is the protective door lock of stone drilling equipment?
The door lock of stone drilling equipment protection door refers to the protection device installed on stone drilling equipment, which can prevent the operator from accidentally touching the switch or entering the dangerous area and causing safety accidents when it is not working. This kind of door lock generally consists of a main frame and a lock, and is interlocked with the machine to ensure that the equipment cannot be started or operated when it is opened.
Second, the stone drilling equipment protection door lock function:
1. Protective function: In the process of equipment operation, if the staff need to open the protective door for maintenance and other operations, they must stop the machine first to complete this process; This not only avoids the potential safety hazard caused by misoperation, but also reduces the risk caused by sudden start-up of equipment.
2. Linkage function: When the protective door is closed, the door lock will send a signal to the controller, so that the machine can start running again; On the contrary, it is the opposite, that is, the equipment can operate normally only when the protective door is closed, which ensures the personal safety in the production process.
3. Reminder function: Some high-end products also have audible and visual alarm, which will automatically trigger an alarm reminder when the protective door is not completely closed or abnormally opened, further enhancing the warning function for employees.
Three, how to correctly choose the stone drilling equipment protection door lock?
1. Determine the use occasion: different types of drilling machines have different characteristics, so the door locks adopted are also different. For example, for small manual drills, a simple mechanical bolt is enough; For large-scale automatic production lines, it may be necessary to use a more complex and reliable electronic control system to realize interlocking control.
2. Pay attention to product quality: 
Good products can not only effectively improve work efficiency, but also ensure the safety of users. Therefore, we should pay attention to check whether the material is durable, whether the process is fine and flawless, and we can also refer to the feedback from other users to make a better judgment.
3. Compliance with relevant laws and regulations: According to the national standard GB/T186972002 on "mechanical safety", "when the machine parts move, measures should be taken to ensure that the human body cannot touch these moving parts." This means that any door lock we buy for this purpose must meet this basic criterion, otherwise we will face the risk of fines or even suspension of production for rectification.
Summary:
In a word, we should comprehensively consider various factors and make a final decision based on our own needs when purchasing the protective door lock of stone drilling equipment. In addition, it should be noted that although low-priced goods may attract consumers' attention, for the sake of life and health of yourself and others, please be sure to choose high-quality brands that are sold through formal channels and have been strictly tested and certified!
