What are the precautions to be taken during the maintenance process of the excavator cutter?

The cutter of the tunneling machine is a component used in every mining project nowadays. It is mainly used in combination with various specifications of coal mining machines and tunneling machines. Usually, a mining equipment will have many Shanxi tunneling machine picks. Due to prolonged and high-intensity work, the cutting teeth are prone to damage and there are various forms of failure. To ensure the normal operation of the cutting teeth of the tunneling machine, if the staff discovers the failure form of the cutting teeth during the work operation, they need to immediately replace the new cutting teeth of the tunneling machine. Let's take a look at the precautions that gear manufacturers should pay attention to during the maintenance process.
1. Observing wear and tear
Firstly, the manufacturer of rotary excavator cutting teeth should observe the degree of wear of different cutting teeth during maintenance. If the failure of the cutting teeth of the tunneling machine is found, it is necessary to replace them in a timely manner, so as to ensure the safety and firmness of the cutting teeth during installation.
2. Backup pick
We need to have sufficient spare cutting teeth for different production processes. Ensure that the replacement of the cutting teeth can be ensured at any time during the production process, so as not to have a significant impact on the production and mining work.
3. Special attention
During the process of repairing the cutting teeth of rotary excavators, operators should observe the condition of the relevant roof and coal walls. When necessary, strengthening support can be chosen to avoid related accidents during the maintenance process.
4. Turn off power
When replacing the cutting teeth on the drum of the tunneling machine, it is necessary to disconnect the power supply of the equipment and open the clutch of the relevant drum.
5. Replace faulty teeth
When replacing the cutting teeth of the tunneling machine, if the operator discovers any abnormal situation, they must immediately stop replacing the cutting teeth to avoid accidents and personal injury of varying degrees.
6. Abnormal situation
If the cutting teeth of the tunneling machine cannot be pulled with a wrench when replacing them, it is necessary to wait for the staff to return to a safe area before turning on the power for inspection and processing.
7. Safe operation
In the process of repairing the cutting teeth of the tunneling machine, relevant operators not only need to have professional maintenance knowledge, but also need to have a strong self-protection awareness, so as not to cause certain degrees of harm to their bodies.
