Design of Automatic Sliding Gate
A Machine Design Project presented to the School of Mechanical and Manufacturing Engineering
Mapua University in partial fulfillment to the requirements in Machine Design 2 (ME152P-2)
1) Rendered and Exploded view of mechanical design
2) Description of Machine
Automatic sliding gate which is a mix of convenience and
automation which operate over a fixed track, with the entirety of the
gate's weight supported by wheels. The track is built along the entrance
and runs at the base of the gate, and the gate is usually operated
automatically. A sliding gate is a type of barrier that may be rolled one
way or the other. Sliding gates offer terrains with a convenient, safe,
secure, and noticeable gateway. The bottom of a sliding gate is a flexible
barrier with bearings. It is simple to open and close since it has no
turning circle.
3) Description of Machine utility
An automatic sliding gate consists of basic components namely
sliding gate, chains, chain bracket, limit switch, socket and plug, and
gate operator. For this design, the following machine utilities are needed
to make the sliding gate function:
AC, or alternating current, means that the gate motor is being
powered directly via the 230V mains supply from a distribution board in
your house. AC motor has a slip ring commutator which allows the
current to continuously change direction in the coil of the ac motor, the
power supply supplies alternating current instead of a direct current
which allows the rotor to rotate in one direction in a magnetic field. The
ac power supply can be produced by a device called an AC generator. A
worm gear is a cylindrical helical gear with one or more threads and
resembles a screw thread. A worm wheel or worm gear is a cylindrical
gear with flanks cut in such a way as to ensure contact with the flanks of
the worm gear. Lastly, a chain can be defined as a series of links
connected by pin joints. Moreover, A chain drive consists of an endless
chain wrapped around two sprockets. The sprockets are toothed wheels
over which an endless chain is fitted.
4) Design Considerations
Health, Safety and Welfare
The health, safety, and welfare aspects of the design considerations are
as follows:
▪ Intelligent drive units to provide inherent force control by
causing the gate to reverse when an obstruction is detected.
▪ Safe edges are touch-sensitive rubber switching strips that
transmit a signal to the gate controller to reverse the gate's
movement when contact is detected.
▪ The placement of a light or radar curtain in front of dangerous
regions. The gate will reverse direction if the curtain is
penetrated while it is working. This may be installed primarily
to protect automobiles, but it will also protect people from
accidental contact.
▪ The "hold-to-run" which means that the gate can only be
opened or closed by a person standing in a safe place and
applying constant pressure to a controller.
Social Factors
The social factors of the design considerations are as follows:
▪ This unique design of a sliding gate features design choices
that could prolong the lifespan of the components within, thus
reducing long-term cost.
▪ This design is for both ease-of-use as well as long-lasting and
durable applications as they do not require complicated
operations to function.
▪ The design of the gate, specifically the motor and gearbox
setup, does not excrete harmful chemicals or substances to the
environment.
Global and Cultural Sensitivity and Awareness
▪ The global and cultural sensitivity and awareness factors of
the design considerations are as follows:
▪ The sizing of the components as well as the gate was
determined and designed to accommodate a wide array of
vehicle sizes to broaden the applications of this gate design
from private suburban properties to industrial plant entrances.
▪ People with any sort of disabilities may be able to use the full
function of this gate as the design has no specific physical
requirements to be operated.
▪ The gate itself may be interchanged to accommodate the
desired privacy for different applications and cultural
environments such as a fence gate for factories and a solid
sheet gate for civilian homes or religious spaces.
