CAGE SUSPENSION GEAR ARRANGEMENTS IN MINES

CAGE SUSPENSION GEAR ARRANGEMENTS

WHAT IS CAGE SUSPENSION GEAR ARRANGEMENTS IN MINES?
The attachment used to attach the rope with cage is known as cage suspension gear.
It consist of a rope capel which is attached to the one end of the rope & its another end is attached to the safety hook through ‘D’ link. The another end of the safety hook is attached to a triangular plate to a ‘D’ link & bull chain. And then at last The triangular plate is attached by the cage chains or Bridle chain.



ROPE CAPEL

Are widely used for connecting the winding rope to the suspension gear. The use of rope Capel is a basic requirement of safety in winding. 










D-LINK



These are used to attach any two components of cage suspension gear & to adjust the height of cage suspension gear. The diameter of the link rod should be 1.5 times the rope’s dia. & should not be any join in the link.



SAFETY HOOK




It is a safety device which acts when an over winding is takes place. Its purpose is to suspend the cage or skip in the headgear if an over winding occurs & at the same to  release the rope Capel to go over the headgear pulley. 
It is always placed just below the rope Capel. 





TRIANGULAR PLATE



Triangular plate is also known as load distributing plates. Its function is to distribute the load of the cage, hence it is known as load distributing plate. 
it consist of one hole at the top which is connected to the safety hook & at the lower end it consists of three holes which are connected to the cage through bridle chains.

BRIDLE CHAINS


These are used to attach the cage with the triangular plate, For a small cage only four chains are used  at the four corners of the cage while in case of large cage total six chains are used. Out of these six chains two central chains doesn’t carry any load & these are used in case of failure of corner chains.

SAFETY DEVICES USED IN HAULAGE ROADWAYS

Safety Devices Used In Haulage Roadways Stop Block: They are made in difficult forms & are used to stop or derail a moving tub on a track. Generally a wooden block which is pivoted to the sleeper at one end is kept across the track to derail the unwanted tubs. The track can be cleared by positioning the wooden block inclined with the track. It is used in direct rope haulage & main & tail rope haulage Backstay or Drag : These are used behind an ascending set of tubs as a safe guard against a broken rope or coupling. It is very strong & made up of steel of rail section. If the tub coupling or rope breaks, the ascending tub starts moving backward. At the pointed end of the drag gets fixed in the ground or sleeper to derail the tubs. It is used in direct rope haulage. BUFFERS When any roadway or face is in direct line with a haulage track and persons may be exposed from runaway tubs, strong buffers is provided and maintained on haulage road to prevent da...

LOAD HAUL DUMP MACHINE (LHD) IN UNDERGROUND MINES

LOAD HAUL DUMP MACHINE (LHD) LOAD HAUL DUMP MACHINE L.H.D is used in underground mines for the loading, hauling and dumping of the material from the working face. L.H.D’S  are used in more than 75% of the u/g mines throughout the world.  L.H.D are available in both Diesel & Electric versions. Diesel version is easily transportable from one location to another and have diesel engines as power drive of 75 to 150 HP or more. Engines are either water or air cooled. L.H.D with Electric motors as drives have general capacity of 75 to 150 HP. These are operative at medium voltage of 380 to 550 volts. Flexible trailing cables are provided with reeling/unreeling facility to feed power. In L.H.D machine an axial piston type motor is used. The maximum speed of L.H.D is nearly, 8-10 km/hr. when the  machine is Empty.  But when the L.H.D machine is loaded the maximum speed is 3-5 km/hr. The standard bucket capacity of the L.H.D is  1.6...

TYPES OF ROPE HAULAGE USED IN UNDERGROUND MINES FOR THE TRANSPORT OF ORE.

Types of Rope Haulage 1)Direct rope haulage:- a)Single drum direct rope haulage b)Double drum direct rope haulage 2)Main & tail rope haulage 3)Endless rope haulage:- a)Under rope endless rope haulage b)Over rope endless rope haulage 4)Gravity rope haulage 1)Direct Rope Haulage a)Single Drums Direct Rope Haulage : This is simplest system of rope haulage.  It consists of one track , one rope & one drum which are connected to a motor through gears.  One end of the rope is connected with the train of tubs on the track & another end of the rope is connected to the drum.   When the drum rotates situated at the top of the incline , the loaded tubs moves upwards.   But for the downward journey of the empty tubs it does not require any power because a tub moves downward due to their own weight.   The system can be on inclines steeper than 1 in 12 & the speed of the haulage is 8-12 km/h. ...
