Design and Fabrication Of Motorized screw jack -Mechanical Project

SYNOPSIS

This project work titled “FABRICATION OF MOTORIZED SCREW JACK” has been conceived having studied the difficulty in lifting the any type of light vehicles. Our survey in the regard in several automobile garages, revealed the facts that mostly some difficult methods were adopted in lifting the vehicles for reconditioning.

Now the project has mainly concentrated on this difficulty, and hence a suitable device has been designed. Such that the vehicle can be lifted from the floor land without application of any impact force. The fabrication part of it has been considered with almost case for its simplicity and economy, such that this can be accommodated as one of the essential tools on automobile garages.

INTRODUCTION
This device the motorized screw jack for automobile garages has been developed to later the needs of small and medium automobile garages, who are normally man powered with very minimum of skilled labours. In most of the garages the vehicles are lifted by using screw jack. This needs high man power and skilled labours.

In order to avoid all such disadvantages. This, motorized screw jack has been designed in such a way that it can be used to lift the vehicle very smoothly without any impact force. The operation is made be simple that even an unskilled labour can handled, by just demonstrating the working of the motorized screw jack once. The d.c motor is coupled with the screw jack by spur gear mechanism. This is an era of automation where it is broadly defined as replacement of manual effort by mechanical power in all degrees of automation. The operation remains an essential part of the system although with changing demands on physical input as the degree of mechanization is increased.

WORKING PRINCIPLE
The lead-acid battery is used to drive the d.c motor. The d.c motor shaft is connected to the spur gear. If the power is given to the D.c motor, it will run so that the spur gear also runs to the slow speed of the D.C motor. The screw jack and moves the piston upward, so that the vehicle lifts from ground.

The vehicle is lifted by using the lifting flat form in the top of the screw jack. The motor is drawn supply from the battery. The lifting and uplifting is done by changing the battery supply to the motor simply.

ADVANTAGES
1. The loaded light vehicles can be easily.
2. Checking and cleaning are easy, because of the main parts are screwed.
3. Handling is easy
4. No Manual power
5. Easy to Repair.
6. Replacement of parts are easy

DISADVANTAGES

  • Cost of the equipment is high when compared to ordinary hand jack.
  • Care must be taken for the handling the equipment such as proper wiring connection, battery charging checkup, etc.

APPLICATIONS
1. It is very much useful in auto-garage. This motorized screw jack is used for lifting the vehicles.
2. Thus it can be useful for the following types of vehicles in future;
Maruti, Ambassador, Fiat, Mahindra
