Abstract - The need of technology for increasing luxury in lifestyle is growing at very fast rate. The elevators, used to avoid
climbing the stairs is growing demand world-wide. But some multi-storeyed building can’t afford generator or battery charged by external source. This problem can be avoided by using Rack & Pinion arrangement in elevator that can charge the battery to avoid the problem faced during electricity cut-off. This system is used to make elevator regenerative for backup. The pinion arrangement is done on the cage and Rack is attached vertically on height of the wall. Key Words: Regenerative, Elevator, backup, plan, evacuate.
1. INTRODUCTION This emergency elevator system is designed to evacuate people during an emergency conditions from a high-rise building. This system can facilitate emergency entry of rescue workers as well as exit of people from a building during emergency condition and at the same time using only the passenger’s weight in the absence of electric power. This elevator system will help people to escape from a disaster-affected building while transporting rescue team to the disturbed floors in a building at the same time – as efficiently, safely and quickly as possible.
1.1 AIM AND OBJECTIVE
To design the new system which can operate when the electricity is off. No conventional fuel use like petrol, diesel, gas etc……… Eco friendly Handling must be easy It is having Higher efficiency Easy to conveyance Works at emergency conditions
1.2 WORKING PRINCIPLE The complete diagram of the power generation using Rack and Pinion arrangement is given below. This system can facilitate emergency entry of rescue workers as well as exit of people from the building in emergency conditions and at the same time while using only the weight of the passengers in the absence of electric power. The body of elevator is connected with the rack, whenever elevator move up and down, rack moves up and down in vertical direction. Pinion is connected with the rack and reciprocating motion of rack is converted to rotary motion by help of pinion. This rotary movement is converted to the electrical energy by Generator shaft.
