The demolition robots are used in dismantling concrete buildings. However, some conventional methods of mining can still be used. Demolishing of a concrete element is a very time consuming and a hard task if done manually. The new world has come up with a new alternative for this i.e. the demolition robots.
Demolition robots make your task very simple and easy. These robots can be used in various sectors like emergency rescue, nuclear energy, metallurgy and much more. The robot looks like a mini excavator. The hydraulically powered arm is the most important part and feature of a demolition robot. The breakers, crushers and drills are attached to these arms. They are flexible, can be controlled easily and are of a compact size.
The demolition robot has four systems. The three arm system and the other are breaking hammer system. Hydraulic cylinder is fitted in every system along with a hammer. The demolition robots have three parts in an excavator which makes them more flexible. Demolition robots include various functions like:
- High safety
- Energy conservation
- Increased operational efficiency
- Stable operation
- Low vibration
- Low noise
- High accuracy
Demolition robots can be used in a cement industry, constructing tunnels, bombing mines and rescue operations.
Working Mechanism
The working mechanism of a demolition robot depends on a heavy-duty hydraulic system manipulator. The manipulator will make different working postures and enhanced working range. The hydraulic pump provides the force required for operating the hydraulic cylinder and this provides pressure on the stored fluid in the reservoir. The fluid then flows from the hydraulic pump through hoses to the cylinder at required pressure. The valves will redirect the flow in the proper direction at the required rate. The robot can then perform the operation as required.
The hydraulic integrated system includes a walking and rotary mechanism and manipulator. The robot contains a wheel or a track that lets the robot to show movements and carry out demolition processes. It uses a hammer to break concrete structures. The arm contains a coupler to connect and simplify the breaker, bucket, drill, shear and grab.
The initial power can be a motor or a diesel drive. The system will have a cooling system to prevent issues related to heat and associated failures.
Caution
There are several facts that need to be kept in mind while operating a demolition robot.
- Prepare a job risk analyses with an operator to minimise less destruction.
- Use and abide by the safety instructions laid down by the manufacturer to build a risk zone within which a machine is working.
- Remember to stay out of the risk zone whenever a machine is working and also make sure that no trespasser enters it until the machine is de-energized or stopped.
- Consider the warning signs of RFID to maintain a safe zone for yourself.
- Training operators should manage Hydraulic tools power cables and continuously monitor the demolition process.
- The spotter must assist the operator.
Conclusion
The human-robot interactions should be as safe as possible. The NIOSH has created a proper research on this. These machines should be operatod vigilantly under expert supervision.
