 Example 1:
 figure 1 As shown in the figure, the base 3 on one side of the ram 4 is provided with a straight rail, and the other side is provided with a straight rail 1 and a switch rail 2 at the same time; the ram 4 provided on the base 3 is simultaneously provided with a straight transition rail 6 and a switch rail Transition rail 7; the motor 8 and screw 9 of the ram driving device are arranged in the internal space of the ram (see diagram 2-1 ), one end of the screw is located in the thread fixed in the boss 10 on the base, and the other end of the screw is connected to the motor shaft or the motor decelerating device. The driving device is controlled by the travel switch or pressure sensor on the ram or the boss. stroke.
 image 3 As shown in the figure, both ends of the straight transition rail 6 and the divergence transition rail 7 arranged side by side on the ram are fixedly installed on the ram, while the straight transition rail and the divergence ...
 Example 2
 Figure 5 As shown, a positioning device is provided between the ram 3 and the base 4. The positioning device is composed of a positioning sleeve 13, a positioning sliding shaft 14, a sliding shaft sleeve 15 and a driving device, and the sliding shaft in the positioning sleeve or located in the positioning sleeve The outer end of 14 is equipped with a travel switch or pressure sensor that controls the operation of the sliding shaft. In the sliding sleeve or the inner end of the sliding shaft in the sliding sleeve, there is a travel switch or pressure sensor that controls the return stroke of the sliding shaft; in the sliding sleeve 15 or at the inner end of the sliding shaft in the sliding sleeve, there is also Pressure sensor that controls the ram drive.
 In application, when the traffic state of the turnout needs to be changed, the driving device power supply in the positioning device is turned on in the reverse direction, and the sliding shaft ...
