Drill rod threads are divided into several main types, including square threads, taper pipe threads, spiral threads, and straight threads. These threads have their own unique characteristics and are suitable for different drilling conditions and requirements. The selection of thread type depends on factors such as the diameter of the drill rod, the material to be drilled, the drilling depth, and the torque required. It is recommended to consult professionals or manufacturers for specific selection advice to ensure that the drill rod threads meet the needs of the project.

Mining, traffic, tunnels, water conservancy construction, quarries and other work

Before using the YT29A rock drill note

1、Check the integrity and rotation of all parts (including rock drill, bracket, or rock drill cart) before drilling, fill necessary lubricant, and check whether the wind and waterways are smooth and whether the connection joints are firm.

2、Knock on the roof near the working face, i.e. check whether there are live rocks and loose rocks on the roof and second gang near the working face, and make necessary treatment.

3, the working surface of the flat shell hole location, is to be pounded flat in advance before allowing rock drilling, to prevent slippage or shell hole displacement.

4. It is strictly forbidden to drill dry eyes, and we should insist on wet rock drilling, turn on the water first and then the wind when operating, and turn off the wind and then the water when stopping drilling. When opening the hole, run at low speed first, and then drill at full speed after drilling to a certain depth.

5、No gloves are allowed to be worn by the drillers when drilling.

6、When using the air leg to drill the hole, pay attention to the standing posture and position, never rely on the body to pressurize, let alone stand in front of the rock drill under the work brazing rod, to prevent injury from broken brazing.

7、If abnormal sound and abnormal water discharge are found in rock drilling, stop the machine for inspection and find out the reason and eliminate it before continuing to drill.

8、When withdrawing from the rock drill or replacing the brazing rod, the rock drill can run slowly and pay attention to the position of the rock drill braze.

Regular maintenance and proper handling of screw drilling tools can help extend their lifespan and ensure optimal performance. Here are some tips for maintaining and maintaining screw drilling tools during use:

1. Clean the tools after each use: Use a soft cloth or brush to remove any debris or dust from the tool. This will reduce the risk of damage or rusting.

2. Lubricate the tools: Apply a small amount of lubricant to the tool’s threads, shank, and cutting edges. This will help to reduce friction and prevent the tool from getting stuck or breaking.

3. Store the tools properly: Keep the tools in a dry place, away from moisture or humidity. Store them in a protective case or wrap them in a clean cloth to prevent damage or corrosion.

4. Inspect the tools regularly: Check the tools for signs of wear or damage, such as dulling or chipping of the cutting edges or threads. Replace any damaged parts immediately.

5. Handle the tools carefully: Avoid dropping or striking the tools, as this can cause damage or deformities to the tool.

By following these tips, you can ensure that your screw drilling tools are well-maintained and perform optimally during use.

Using laser cleaners requires careful attention to safety and operational considerations. Here are some precautions to take when using laser cleaners:

Personal Protective Equipment (PPE):
Wear appropriate PPE, including safety glasses with the correct optical density for the laser wavelength being used. Depending on the laser power and the specific cleaning environment, additional PPE such as gloves, face shields, and protective clothing may be necessary.

Area Preparation:
Ensure that the cleaning area is properly prepared and free of flammable materials or other hazards that could be ignited by the laser beam or the cleaning process.

Ventilation:
Provide adequate ventilation to remove any fumes, vapors, or particulates generated during the cleaning process. This helps maintain a safe working environment and prevents exposure to potentially harmful substances.

Controlled Access:
Restrict access to the laser cleaning area to authorized personnel only. Use signage and barriers to clearly demarcate the laser operation zone and prevent unauthorized entry.

Training:
Ensure that operators are properly trained in the safe use of laser cleaners, including how to operate the equipment, handle laser hazards, and respond to emergencies. Regular training updates and refresher courses are also beneficial.

Beam Control:
Use beam control mechanisms such as beam shutters, interlocks, and beam blocks to prevent accidental exposure to the laser beam. Ensure that the laser beam is directed away from reflective surfaces and bystanders.

Monitoring:
Continuously monitor the laser cleaning process and the surrounding environment for any signs of abnormal operation, such as smoke, unusual odors, or unexpected reflections of laser light.

Emergency Procedures:
Establish clear procedures for responding to emergencies, including laser beam exposure, fire, chemical spills, or other accidents. Provide appropriate emergency equipment such as fire extinguishers, eye wash stations, and first aid kits.

Maintenance:
Perform regular maintenance and inspections of the laser cleaning equipment to ensure proper functionality and safety. Follow manufacturer recommendations for calibration, alignment, and servicing.

Regulatory Compliance:
Adhere to relevant safety standards and regulations governing the use of lasers in your jurisdiction, such as ANSI Z136.1 in the United States or IEC 60825 internationally. Obtain any necessary permits or approvals for operating laser equipment.

By following these precautions and implementing proper safety measures, you can minimize the risks associated with using laser cleaners and create a safe working environment for operators and bystanders.

SCRAPER WINCHES,Underground Mining Scraper Winch

Mining Scraper Winch is mainly used for coal mine & other underground mine or open-pit ore handling and filling operations. It is mainly used for horizontal plane transport and slope dumping with small slope angle, but it cannot be used as lifting equipment. The parallel arrangement of electric tweezers is common to the PB series bucket loading machine.

The main components of the electric tweezers are a speed reducer, a main reel, a secondary reel, an operating device, a steel wire for guide and an electric motor. These components are housed inside and outside the housing. The housing is a component with good rigidity, which serves as a protection, support and full load.

Product Description

The usage of the scraper winch 2JP,2JPB series scraper winch is mainly use in metal mine and other coal mine’s pit and ore’s carrying and filling working,is applicable to the scraping which ground is horizontal or the slope not more than 44 degree.

Do you know the difference between 2JP and 2JPB electric scraper winch?

For 2JP electric scraper winch,the motor is non-explosion proof.

For 2JPB electric scraper winch,the motor is explosion proof.

For ” 2 “,it means the drum’s quantity is two.

For  “J”,it means electricwinch.

For ” P”,it means the electric winch use for scraping.

For “B”,it means the explosion proof electric winch.
