SAFETY FIRST….

THE MACHINES WE DESIGN SHOULD HELP PEOPLE TO LIVE HAPPILY….

MOST OF THE HAPPINESS LIES IN WORKING SAFELY, IN A SAFE ENVIRONMENT….CREATE AND FOLLOW SAFETY AROUND YOU….

LET’S WORK AS A TEAM….

• TEAM WORK ENSURES SAFETY FOR ALL….

….BE PRO-ACTIVE and EXPECT (ANTICIPATE) DANGER IN EVERY SITUATION….IMAGINE AS IF THE SKY COULD FALL ON YOU….PROTECT YOURSELF and ALL OTHERS….

LET’S PROTECT ENVIRONMENT….

• GOOD ENVIRONMENT IS KEY TO MANKIND SURVIVAL.

• AS PER ONE STATEMENT, TOTAL MANKIND ON EARTH WILL PERISH, ONLY AFTER THREE YEARS OF EXTINCTION OF BEES.

• WE NEED TO SUPPRESS POLLUTION and GREEN-HOUSE GASES, etc…

FEW ENVIRONMENT HAZARDS, WE MUST STOP or REDUCE…

• OIL SPILLAGES, WATER and SOIL POLLUTION WITH INDUSTRIAL CHEMICALS, WASTING ENERGY, OVER CONSUMPTION, WASTING FOOD, etc… MUST BE STOPPED…

• INDESCRIMINATE USE OF PLASTICS , PAINTS, etc…CUTTING OF TREES, INDESCRIMINATE MINING, etc… MUST BE STOPEED….

• “3R” s…”REDUCE, RE-USE, and RECYCLE”, should be followed, by all.

SAVE ENVIRONMENT, SAVE EARTH…

The “3R”, s…

• The “3R” s are, REDUCE, REUSE and RECYCLE, should be followed by all of us….

• SAVING THE ENVIRONMENT IS THE GREATEST GIFT, WE TRANSFER TO OUR FUTURE GENERATIONS….

DESIGN OF A DRILLING RIG

FORMATION OF THE IDEA…• The CEO or Chairperson of a firm

Designs and Markets a product to satisfy his needs.

• His / Her needs can be Psychological, Social, Financial, and many more…

• First sell the product then design.

DESIGN OF A PRODUCTWhatever Design, Creation, or

Idea of a Product or Service should satisfy the customer requirements.

Whatever design we do must be competitive also.

PRODUCT DESIGN Contd…

• When customer is satisfied he can come with us for a long distance.

BASIC DESIGN OF A DRILL RIG

• The drill rig can include following features.I). Right type of Kinematics to Perform different

functions, the customer needs.• When we call “RIGHT TYPE” it should satisfy

many requirements. Such as,A). Ease and Safe to operate…B). To meet statutory requirements of the situation

(Mine laws, Environmental regulations, etc…)

SAFETY WARNINGS

A Simple & Compact Drill Rig…

Continuation….Basic Design of a Drill Rig…

C). Optimum cost (To be decided in discussion with customer)…

D). Compactness (Space is more than money in some situations)…

E). Durability (Sufficient strength and Resistance to environment and surrounding conditions)

F). Ease of Maintenance…G). Light in weight and high in Elegance, etc…

Continuation….Basic Design of Drill Rig…

II). Right type of Hydraulics. The hydraulic logics are equally important as Mechanical Logics. Gone are the days of simple pumps, valves and motors.

Present day pumps are load sensing- variable displacement types, with various logical controls to suit the requirements.

The cartridge valves and Manifold Blocks are used to prop-up the actuator control logics.

Hydraulic Logics, continued…

CONTROL PANEL OF A MODERN DRILL RIG…

Hydraulic Motors & Cylinders…The present day hydraulic motors can

operate at high pressures and deliver high speeds and torques.

Bent axis variable displacement motors are of infinitely variable speeds and torques.

Many hydraulic cylinders come with in built counter-balance cartridge valves for better safety.

HYDRAULIC CIRCUIT OF A DRILL RIG…

HOSES and PIPING ON MAST…

SAFE SPIRAL FOR HOSES

HYDRAULICS CONTD…PRESENT DAY HYDRAULIC HOSES ARE MUCH

MORE FLEXIBLE AND CAN HANDLE HIGHER PRESSURES THAN OLDER TYPES.

CONTROL LEVERS ARE MORE SOPHISTICATED, JOY STICK TYPES IN MANY CASES.

DIGITAL GAUGES ARE REPLACING OLDER AND LESS ACCURATE ANALOGUE TYPE GAUGES OF THE PAST.

ADVANCED CIRCUITS WITH CARTDRIDGE MANIFOLDS ARE BECOMING VERY POPULAR.

STATUTORY and SAFETY requirements…

As with technology advances, the legal and safety standards are also higher than in the past.

The “ Falling Object Protection System (FOPS)” at control panel protects the drill-rig operator.

The “Safety Decals” and their placement is made compulsory by some legal terms.

Statutory requirements Contd…Pollution and effluent emissions should

be within the legal limits.The Drill-rig and accessories we design

should meet the environmental norms. Such as the paints we use should be safe to environment.

Oils and Lubricants we recommend should be safe to environment and degradable.

AESTHETICS• The shape and external appearance of a

rig should be attractive to sight.• The paints to be used should be not only

protect the machine from corrosion but also should meet the customers visual taste.

• Such external appearance requirements can be decided in discussion with customer.

TIME FRAMEOne should not take too much

time to design a product, at the same time he should not be too hasty.

Time frame should be decided in discussion with customer.

OTHER THINGS…

• A designer should develop right vendor to optimize cost and quality of the rig…

• Recruit right personnel and train them…• He should develop right processes and

procedures to manufacture the product.• Develop other infrastructure as per

requirement of the product and situation.
