External public relations
As a rotary excavation management personnel, anything is not as important as the external public relations with the Party, should be absolutely obedient to the arrangements, actively cooperate with, according to the Party's work instructions to carry out the work, and make a good relationship, often communicate feelings.
Plan organization
Plan a target every day, realize the connection of the whole production chain and complete the target through the integrated arrangement of people, machines, materials and time.
Control
Supervise safety, production and quality, determine whether the team is moving forward healthily towards the goal, and take corrective measures in time when necessary.
Logistics
To establish a set of logistics management methods, mainly for employees: living and living, labor protection. If a team can't even eat well and rest well, then nothing else is worth talking about! Logistical support is very important, related to human resources issues, which is the root cause of many builders to stay people, in fact, sometimes employees may not be poor?
Rules and regulations
Many employees think that the rules and regulations are binding work, in fact, not. Rules and regulations include: labor contract management, wage management, social insurance and welfare benefits, working hours, vacation, employee rewards and punishments, as well as other labor management regulations. If you don't have a system and implement it, it means that there is a problem in management.
Human resource
Many rotary excavation construction companies are short of people, all day long either recruiting mechanics or recruiting filling workers. In fact, the wages of mechanics are about the same, filling are calculated according to the amount of square, since the money earned in which dry are about the same, why can't we keep people? The reason is worth thinking about. The loss of human resources in any enterprise is the loss of the company, not to mention the role played by a good mechanic in the construction of rotary excavation.
Management team
For the professional ethics, skills and experience there are problems with the staff directly dismissed, so as not to leave hidden dangers, jeopardizing the team and the quality of the project.
Promote team spirit
As a management is to coordinate the activities of others, in order to receive individual activities alone can not receive the effect of activities carried out.
Equipment maintenance
Ensuring the long-term stable operation of equipment is the cornerstone of improving efficiency Understanding the structure and working principle of electromechanical fluids and diesel engines can improve the maintenance skills of equipment.
Mechanical structure
Chassis: four wheels and one belt. H-shaped support, slewing support, slewing on board, counterweight, cab.
Working device: luffing device (luffing arm, luffing cylinder, support bar, triangle), mast (upper mast, middle mast, lower mast), anchor frame, follower frame, lifting and leading device, drilling rod, drilling tools, pin, bushing, reducer.
Maintenance of machinery mainly focuses on inspection: welded parts, screw torque, pin lubrication, regular oil change.
Mechanical inspection focuses on: power head, main reel wire rope, lifter, rope clamp, drill pipe, drilling bucket parts. Electricity Electricity is the weak point of a mechanic, so it is impossible to master it completely! However, some basic knowledge is still needed to master such as: the starting motor (engine) start method, the use of the work device monitor and parameter settings, the role of the solenoid valve and the principle of operation, the role of the relay and so on.
(1) check the electrical wiring for breaks, shorts, breaks, insulation damage and other issues, focusing on checking the wiring harness through the metal holes or around the right angle should be added to the protective sleeve or insulation insulation.
(2) It is best to use a multimeter, 10 minutes to learn simple measurements, electrical faults can be measured and diagnosed.
Hydraulic
Convert mechanical energy into hydraulic energy: hydraulic pump. Hydraulic energy into mechanical energy: hydraulic motor.
1, the hydraulic system consists of five parts: the power element (hydraulic pump), the implementation of elements (motor, cylinder), control elements (valves), auxiliary components (tanks, radiators), the working medium (hydraulic fluid)
2, the main pump system (main pump 1 main pump 2. Two sets of main valves) mainly to the motor oil supply.
3, auxiliary pump system: auxiliary pump (load-sensitive variable pump) through the load pressure feedback control swashplate, M4 valve (solenoid proportional valve) is mainly used to control the mast action, M4 valve also contains pilot and solenoid valve control mode, auxiliary pump is mainly to the whole vehicle cylinder oil supply.
4、Pilot system: pilot pump (gear quantitative pump), accumulator, battery valve group, pilot proportional valve, used to control the main valve, M4 valve, brake system.
5、Hydraulic Maintenance: Replace the hydraulic oil and filter element regularly, strictly use the specified oil and pure parts, select the viscosity of hydraulic oil according to the ambient temperature. Check the fluid level before starting the machine, and filter it regularly, etc.
Engine
The current rotary drilling rigs are equipped with two major brands of engines: Caterpillar, Cummins.
1, the mainstream technology: inline six-cylinder, water-cooled, EFI (high pressure common rail), turbocharging, intercooler, programmable ECM controller and so on.
2, the engine maintenance: the use of designated oil, the use of pure components, on time regular maintenance, diesel <, oil, antifreeze, air to develop management methods, such as: daily clearing and release of water in the oil-water separator, the bottom of the tank of impurities and water, as far as possible before leaving work to refill the fuel (air containing water).
3, maintenance details: replacement of oil can not use diesel fuel to clean the engine; replacement of diesel filter filter can not be filled with fuel or oil inside the cartridge (filled with part of the oil body is not filtered); installation of the cartridge, when the sealing ring is stressed, hand-twisted two turns can be; engine low-temperature start-up needs to be warmed up, high temperature shutdown needs to be idling before the cooler. Regular maintenance maintenance Whether mechanical, electrical, hydraulic, engine need regular and periodic maintenance, daily, weekly and monthly inspection, 250h.500h.1000h.1500h.2000h ..... Regular maintenance and replacement of component oils.
