How To Avoid Short Circuit Of Transfer Carts On-Rail?
The transfer carts on-rail is an electric material handling cart powered by low voltage rails. This kind of transfer cart need insulation between track and ground to avoid short circuit and affect normal use of carts.
Due to the wireless low-voltage power supply, there is no cable dragging and winding, which is conducive to the layout of the workshop and the passage of rail guided vehicles and pedestrians. Therefore, in practical application, it is mainly used in the working environment with long running distance and high frequency.
The raw materials needed for laying the low-voltage electric flat cart track include cement, sand, stone, track, track accessories, resin or linoleum, compensating copper, horizontal hand drill and other tools.
First of all, use the level to find the leveling layer on the track bearing ground beam on the ground, and use cement to increase the height to ensure that all tracks are on the horizontal plane, and calculate the height of the corresponding track. The difference between the upper plane of track and the ground after construction.
In the middle of the track and the ground beam, the asphalt felt or resin is used to ensure the insulation of the low-voltage track electric flat transfer cart track, and the embedded bolts are placed in the reserved holes of the ground beam, and the ash is cast with sand and solidified on both sides of the track. The distance between the bolt and the guide rail is determined by the specification of the guide rail presser foot.
Check the gauge and rail level of the low-voltage rail electric flatbed cart, and the difference is plus or minus 3 mm, so as to avoid the wheel electric vehicle running, and the wheel can not contact with the track surface at the same time.
And the resistance of the measured track should not be greater than 10 ohm. When the low-voltage insulated track is laid outdoors, attention should be paid to the treatment of accumulated water, so as to prevent the track short-circuit caused by excessive water, which will affect the normal use of low-voltage rail powered transfer cart.
