The hydraulic anchor bolt drilling vehicle is an important mechanical equipment widely used in engineering fields such as mining, tunnels, and slope reinforcement. It is mainly used for anchor bolt drilling construction in rock mass reinforcement. Due to its complex working environment, large equipment structure and strong power, the safe operation of the hydraulic anchor drill truck is particularly important. Reasonable and standardized operation not only ensures the life safety of construction workers, but also effectively extends the service life of equipment, improves construction efficiency and avoids economic losses. This article will focus on the structural features and operation procedures of the hydraulic anchor drill truck, systematically sort out the safety matters that must be followed during its operation, covering equipment inspection, personnel protection, operation norms, environmental requirements, and emergency response, etc., providing comprehensive safety guidance for relevant personnel.
I. Structural Features and Safety Risk Analysis of Hydraulic Anchor Drill Truck
The hydraulic anchor drill truck is mainly composed of the power system, hydraulic system, drill pipe and drill bit system, slewing mechanism, outriggers and chassis, control system, etc. Its power is transmitted through the hydraulic system to drive the drill bit for drilling operations. The equipment is relatively large in size, with obvious vibration and noise during operation. Moreover, it is mostly operated in narrow and complex terrain construction site environments.
The main security risks include:
Mechanical injury risk: Rotating parts, hydraulic components and lifting mechanisms are at risk of being pinched or collided.
Hydraulic system leakage risk: High-pressure oil leakage may cause fire or slip accidents.
Environmental risks: The working area is mostly composed of unstable rock masses, posing risks of collapse and landslides.
Operator risk: Improper operation or insufficient protective measures may lead to accidents.
Therefore, the awareness of safe operation and standardized operation procedures are of vital importance.
Ii. Safety Preparations Before Operation
1. Qualification requirements for operators
Operators must undergo professional training and hold relevant certificates to work.
Be familiar with the structure and performance of the equipment and master emergency handling skills.
2. Comprehensive inspection of the equipment
Hydraulic system inspection: Confirm that the oil is sufficient, there is no leakage, and the oil pipes are firmly connected.
Mechanical component inspection: The drill pipe and drill bit are intact and undamaged, and rotate flexibly.
Safety device inspection: The emergency stop button, limit device and alarm are functioning properly.
Electrical system inspection: The cable insulation is good and the grounding is reliable.
Lubrication system inspection: Sufficient and evenly distributed lubricating grease.
3. Construction environment assessment
Assess the stability of the operation site and eliminate the risk of collapse.
Ensure that there are no open flames or flammable and explosive items in the construction area.
Obvious safety warning signs are set up at the construction site.
Iii. Safety Precautions during the Operation of Hydraulic Anchor Bolt Drilling Vehicles
1. Preparations before startup
Before starting the equipment, it should be ensured that all personnel are away from dangerous areas.
The startup program should be operated in the prescribed sequence to avoid mechanical shock.
When starting up, pay attention to the operating status of the equipment. If any abnormality is found, stop the machine in time for inspection.
2. Safety of drilling operations
It is strictly prohibited to adjust the drill pipe or touch the rotating parts when the equipment is in operation.
During the drilling process, the hydraulic pressure and temperature should be monitored to prevent system overload.
Control the drilling speed to avoid mechanical failure caused by excessive speed.
After the drilling is completed, the lifting action of the drill pipe should be slow and steady to prevent injury to personnel.
3. The outriggers operate safely
When the outriggers are extended or retracted, it is strictly prohibited for personnel to loiter under the outriggers or in the areas affected by them.
Make sure the outriggers are stable to prevent the equipment from tilting or sliding.
4. Equipment mobility security
Before moving the vehicle, make sure the surrounding environment is cleaned up and all personnel have evacuated.
Keep a low speed while moving and avoid sharp turns and sudden braking.
After moving to the construction site, the legs should be re-supported and fixed.
5. Personal Protective Equipment (PPE
Operators must wear safety helmets, protective gloves, protective shoes, dust masks and goggles.
According to the requirements of the working environment, noise-canceling earplugs, shock-absorbing clothing, etc. should be provided.
Iv. Safety Matters in Hydraulic System and Mechanical Maintenance
Maintenance of the hydraulic system
Before maintenance, the power source must be cut off and the system pressure released completely.
Use qualified hydraulic oil to avoid oil contamination.
Regularly check whether the hydraulic pipelines are aged or damaged and replace them in a timely manner.
Avoid hydraulic oil leakage. Repair it immediately if leakage is found.
2. Maintenance of mechanical components
When the drill bit and drill pipe are severely worn, they should be replaced in time.
The lubrication system maintains good lubrication to reduce mechanical wear.
Check all the fasteners to prevent loosening.
V. Safety Management at Construction Sites
1. Division of safe operation areas
Clearly demarcate the operation area, hazardous area and safety passage.
Non-operation personnel are not allowed to enter the dangerous area.
2. On-site environmental monitoring
Monitor the stability of rock masses in real time and take measures promptly when any abnormality is detected.
Maintain good ventilation at the construction site to reduce the accumulation of harmful gases.
3. Safety signs and warnings
Prominent safety warning signs and operation specification prompts are set up at the construction site.
Operators must strictly abide by the on-site safety regulations.
Vi. Emergency Response Plan and Accident Handling
1. Emergency response plan formulation
Formulate emergency plans for various emergencies, including fires, mechanical failures, and personal injuries.
Regularly organize emergency drills to enhance the emergency response capabilities of personnel.
2. Accident Handling principles
Immediately cut off the power supply and hydraulic power after the accident and stop the operation of the equipment.
Evacuate the people on the scene quickly and provide medical treatment to the injured.
Keep the scene and wait for professional personnel to investigate and handle it.
Vii. Summary
As an effective rock mass reinforcement equipment, the hydraulic anchor drill truck has various safety risks during operation. Only through standardized operation procedures, strict equipment inspections, comprehensive personnel training and scientific on-site management can construction safety be maximized and accidents be avoided. Operators should always maintain a sense of safety, strictly follow safety operation procedures, and adhere to the principle of prevention first to nip potential problems in the bud, providing a solid guarantee for the smooth progress of the project and the safety of personnel.
