1. Main application and functions
The pitless train shunting stand is new type equipment developed by our institute on the basis of absorbing advantages of same products in developed counties. It is applied for shunting train whose weight is not more than 150 tons. The shunting stand is composed of frame, operation station, transmission, transition bridge, pull organ, power supply device for driver cabinet and electrical control system etc.
The shunting stand applies manual operation to realize running, track alignment, stop etc functions. Also it can add auto track alignment and camera monitor system. The stand has "advance", "back", "fast", "slow", "crawl" etc functions.
Control system applies controller, transducer to realize motor synchronous action and exact control and to adjust speed. So it ensures that the shunting stand can start, run and stop steadily and improve safety and stability when running.
Electrical control system has over-load, overcurrent, overheating, under voltage, short-circuit, lack of phase, etc functions. It has motor short-circuit protection for random 2 phases, earth-leakage protection for A&B phase, protection for motor overload and overheating and earth-leakage protection for random point.
Before shunting stand start and when it is running, it has light-electric indicator and alarm.
The shunting stand can equip 1 or 2 operation stations according to customer's request. The 2 operation stations are interlock, so it is allowed to operate only at one station.
There are emergency stop buttons at four angles of shunting stand. Press emergency stop button can cut all electricity.
The shunting stand has lock and caution function after track alignment function, the shunting stand can't move when train get up and down.
It has the function of limit position protection on both sides of shunting stand. There are stop block and electrical limit switch, when impact device touch stop block, the position switch open and cut off the power supply. When buffer device touch stop block, the shunting stand stops.
