Abstract
A trolley car was built for the exclusive use of transporting in vinyl houses.
The mechanism and performance of this car are summarized as follows:
(1) The trolley car was equipped with a D. C. motor as the prune mover. The voltage and output of the motor was 12V and 144W respectively.
The car had one driving wheel and four supporting wheels. The driving wheel ran in the guide rail that was made of L type steel. The car could be loaded with 50kg for the standard use and its traveling speed was about 0.3m/s.
(2) A portable generator (1.2V, 10A) or a rectifier (12V, 20A) was used as a source of electric power, and the electric current flowed through the trolley duct installed and the trolley to the motor in the car. The trolley slided in the trolley duct as the trolley contacted with the conductor of the trolley duct.
(3) Input of the motor was about 116W and about 124W when loaded 50kg and 100kg respectively, and there was no significant difference in inputs between the portable generator and the rectifier that were used for the source of electric power.
It seemed that the capacity of the portable generator was not enough when pulled one car with a load of above 70kg.
There was no significant difference in inputs between straight and curved (R=1.7m) guide rails.
(4) The car could be loaded 90kg (input was about 120W) and 50kg (input was about 134W) in the case of 2.5deg, and 5deg, climbing angle respectively.
(5) As a result of simulation of transporting, no accumulation of cargo occurred even in the case of 10 pickers when the transporting distance was 40m. Therefore it seemed that the some travel speed could be reduced under 0.3m/s, when it would be used in common vinyl houses.
