ABSTRACT
This mechanical projects presentation is a model and a simplified version of kattwyk bridge.
The bridge mechanism has been divided into three sections.
The central section lifts above,while the two slide parts remain intact with the supporting angles.
The lift mechanism is used for the bridge is based on the pulley system involving three pulleys.
The string is passed through the two pulleys on either side of middle section to lift the bridge.
INTRODUCTION
The motivation behind the project is the KATTWYK BRIDGE, HAMSBERG, GERMANY.
The bridge was built in 1972. The bridge has a unique feature that it based on the “Vertical Lift Mechanism”.
Its middle (movable) part lifts to give way to the ship passing by thus maintaining waterways transport.
Till now no bridge such has been built in India.
DESCRIPTION
This project is a model and a simplified version of Kattwyk Bridge and has been made under the constraints of space, time and resources available in the lab. The Bridge mechanism has been divided in three sections.
The central section lifts above, while the two side parts remain intact with the supporting angles. The lift mechanism used for the bridge is based on the pulley system involving three pulley
A string is passed through the two pulleys on either side of middle section and the pulley at the centre synchronizes the motion of two pulleys and makes the motion centralized.
The angles are used to restrict the motion of central section allowing only the motion in vertical direction to occur and provide the stability to the bridge structure.
A chain is also used to stop the central section at any desired height depending on the height of ship assuming a real case situation thus saving the power.
OBJECTIVES
The vertical lifting mechanism is used to lift the bridges.
The mechanism is used to save the time.
In this mechanism the central part can be stopped at any desired position.
WORKING
The mechanism works by using an electric motor.
Power is transmitted to central by using ropes.
The ropes lift the central part upwards.
By using self locking gears we can stop central part at any desired position.
ADVANTAGES
Time saving.
Low cost.
Less power required.
To lift central part at any desired height by increasing the beams
CONCLUSION
This project work has provided us an excellent opportunity and experience, to use our limited knowledge we gained lot of practical knowledge regarding, planning, purchasing, assembling and machining while doing this project work.
The Vertical Lifting Mechanism is working with satisfactory conditions.
We have done tolerable and skill making use of available facilities.
