The winder is a 4-rope Koepe winding machine with integrated motor. This type of design of the winder guarantee long-term stability of the entire drive system. Assembly of the winder in the workshop. 4-Rope Koepe winder. 3+1 Channel brake system. ▫ Statement of the investment and operating costs. ▫ Comparison of . The objective of this study is to monitor four Koepe winder head ropes, which have six triangular-shaped strands and are 38 mm in diameter, by.

May 15th,Published in Articles: The kopee represents the shaft, to a reduced scale. The bridle is now directed into the guides and hinged guides are closed and secured. That caused a heavy wear and tear of the rope. Arrangement for attaching the chain block to the cappel. Reference to comparable plants elsewhere. The Blair multi-rope hoist is a variation of the double-drum hoist.
Manufacture of key components in house, otherwise by sub-contractors in Australia. Design The Olympic Dam Shaft 3 is designed as a downcast shaft for a capacity of 9. In the case of conventional winders, changes in the clearance of the motor which is mounted on separate bearings may be caused koeppe settling processes, which in some cases have led to complete standstill of the hoisting machinery due to failure of the motor.
Headgear To a large extent, the headgear is designed as a box-type structure with a minimum of smoothly painted surfaces which make it especially resistant to corrosion. Comparing the performance of different ropes under specific Koepe or drum winder.
In order to make the construction time as short as possible, the following decisions were taken: The skips are of the swing-out type with a large cross section allowing rapid loading and unloading. The winder is moved to release the suspension clamp on the new rope at bank level.
Steel support columns position the cradle. A carriage mounted on rollers and holding a permanent magnet is rotated round the centre thread, guided by two vertical rods driven from the winder drum shaft.
Each set of rope sheaves on the headgear is mounted by means of anti-friction bearings on a stationary axle. Koele of a tail rope. The skip bridle has no gear for equalising the tension in the four ropes. Home Sitemap Links Imprint Contact. The head rope to be changed is disconnected from the bridle and the cappels is removed.
The shaft bottom construction serves a two-fold purpose — all shaft conveyances are stopped at this level in the event of an accident, and the tail ropes are protected.
The wonder process in the drum winder is concetrated at the back end at which the rotation deformation is constant: The skips are discharged by swinging out the tubs by use of slewing beams operated by hydraulic winddr.
Its peripheral length is approximately 65 feet. The layout of the winder is shown in Fig 6. Spillage from the loading flask is negligible if the skip positioning magnets are located accurately.
The pans are then returned to their respective bridles. To remedy this, the helical controller and the Ardic controller are driven from the main shaft of the winder through a servo-motor operated differential gearbox.
The speed reference is immediately reduced to zero and the winder retards at the rate defined by the amplifiers.
The loading flask is also designed for weighing the skip load. The total weight of the head ropes, skips, tail ropes and a single payload is approximately tonnes. The two main winders at ground level are fully occupied handling material and men while the Koepe winder handles all the ore from the lowest loading place in the shaft.
After that one of the pit cages arrived at the onset of a certain level and the other one arrived at the pit bank, there is a strong difference concerning the sharing of the loads: The deposits concerned are enormous approx. The attached chain block is used for this purpose. The tail rope is disconnected from the conveyance at the loading box and is lowered to the bottom of the shaft. The Koepe wheel is 5,8 m diameter. The beams support steel top-hat guides arranged in camel back form T to deflect spillage or material away from the loop of the tail ropes.
Loading flask The loading flask is also designed as a removable container and is lined with special steel plates, too.
This test for a fatigue rope may provide usefull informaiton on hte discard criteria, residual breaking load, the remaining service life and the rate of windeer. Principles and testing methods of earth ground resistance. Sealed ball-bearing swivels where each tail rope attaches to the bridle tailpiece release any residual torque or kpepe which may build up. The clamps on the tail rope are removed and the supporting steelwork taken from the compartment.
The setting can be adjusted by means of sliding resistances.
Definition of Koepe winder – glossary
Click to learn on: Two 2,5 cm diameter slings are passed koeepe the bridle crosshead and secured to the steelwork at the station. A case study in two parts, detailing the installation of a Koepe winder at a busy mine shaft. The conveyances are klepe to the rope installation positions, one above the loading box, the other about 9 m above the bank in the headgear.
In the headgear, two reinforced concrete beams are situated below the winder floor approximately 4 m deep and 1,2 m wide, crossing the headgear structure and carrying the winder. This dispenses with the frequent greasing required by the conventional design with bronze sleeves. Two tonne hydraulic jacks raise and support the drum shaft.
The clamps and their supports were removed. It is essential that the tread grooves on the Koepe wheel be kept to the same diameter. By the turn of the century, his new technology was already being used in mines in England and America. This design allows the skips to be brought into their unloading position with maximum speed and avoids unnecessary loading of the headgear through high-dynamic impacts.
