CN205451655U discloses an automatic demonstration teaching mould of coupling tristate test. The three-state process of the car coupler can be rapidly and intuitively automatically demonstrated through the mould.
Fig. 1 shows a schematic view of the hook locking position.
When the coupler knuckle 5 is in a locking position and the coupler is in a closed state when the coupler pin 2 is in a falling state, the coupler is in a locking state as shown in fig. 1.
Figure 2 shows a schematic diagram of a coupler unlocking position.
When the coupler knuckle 5 is not rotated when the coupler pin 2 is lifted slowly, the coupler is in an unlocked state, and the coupler knuckle can rotate freely around the coupler knuckle pin 4, as shown in fig. 2.
FIG. 3 shows a schematic diagram of a fully open position of a coupler.

figure 4 shows a schematic diagram of a coupler coupling state.
And when the car couplers on the two sides are in the full-open state, the car couplers on the two sides can be coupled, and the state after the coupling of the car couplers on the two sides is finished is shown in figure 4. And (3) the coupler lock pin 2 is dropped, the couplers on the two sides are in the locking position, and the coupler lock pin 2 is dropped to ensure that the coupler is normally locked.
The states of the full-open position, the locking position, the unlocking position and the like of the coupler need to be confirmed and checked in a manual mode, a locomotive driver can check the state of the coupler according to the full-open standard of the coupler before the coupler is linked, the linking operation can be executed when the linking condition is met, and if the coupler is not in the full-open position, the locomotive driver needs to manually open the coupler to the full-open position.

Fig. 7 shows a block diagram of a motion conversion mechanism of the coupler three-state detection device according to the present invention. Fig. 8 is a top view of a motion conversion mechanism of a coupler tri-state detection arrangement in accordance with the present invention.
As shown in the figure, the motion conversion mechanism 7 comprises a reference plate 11, an induction shaft 12, an induction shaft sleeve 13, a connecting pin 14, an L type connecting rod 15, a fixed seat 16 and a rotating pin 17, wherein the reference plate 11 is welded on a mounting bracket 8, the knuckle sensor 6 and the induction shaft sleeve 13 are mounted on the reference plate 11, and the central line of the knuckle sensor 6 and the central line of the induction shaft sleeve 13 are ensured to be in the same straight line, the induction shaft 12 is sleeved in the induction shaft sleeve 13, the induction shaft 12 can slide in the induction shaft sleeve 13 and do linear motion, the L type connecting rod 15 is connected with the induction shaft 12 through the connecting pin 14, the L type connecting rod 15 and the induction shaft 12 form a certain angle, as shown in figure 8, the induction shaft 12 is conveniently pushed by the L type connecting rod 15 to slide in the induction shaft sleeve 13, the L type connecting rod 15 is connected with the fixed seat 16 through the rotating pin 17, the L type connecting rod 15 rotates with the rotating pin 17 as a shaft.
FIG. 9 is a schematic illustration of a fully open position of a coupler according to the present invention.
As shown in fig. 9, when the coupler knuckle 5 rotates clockwise by 45 ° around the coupler knuckle pin 4, in the process of converting the unlocking position into the full opening position of the coupler, the coupler knuckle 5 drives the fixed seat 16 to rotate synchronously, the fixed seat 16 drives the L-shaped connecting rod 15 to move through the rotating pin 17, under the action of the L-shaped connecting rod 15, the sensing shaft 12 moves leftwards along the sensing shaft sleeve 13 in the sensing shaft sleeve 13, at this time, the rotational motion of the coupler knuckle 5 is transmitted to the sensing shaft 12 and converts the rotational motion of the coupler knuckle 5 into the linear motion of the sensing shaft 12, when the sensing shaft 12 moves to the leftmost end, the sensing shaft 12 extends into the detection range of the coupler knuckle sensor 6, the coupler knuckle sensor 6 is triggered, and the system displays that the coupler is in the full opening position.
When the coupler knuckle 5 rotates around the coupler knuckle pin 4 by less than 45 degrees, in the process that the coupler is converted from the unlocking position to the full-open position, the coupler knuckle 5 drives the fixed seat 16 to synchronously rotate, the fixed seat 16 drives the L-type connecting rod 15 to move through the rotating pin 17, the induction shaft 12 moves leftwards along the induction shaft sleeve 13 in the induction shaft sleeve 13 under the action of the L-type connecting rod 15, at the moment, the movement of the coupler knuckle 5 is transmitted to the induction shaft 12, the rotation of the coupler knuckle 5 is converted into the linear movement of the induction shaft 12, the induction shaft 12 does not move to the leftmost end due to the fact that the rotating angle of the coupler knuckle 5 is insufficient, the induction shaft 12 does not extend into the detection range of the coupler knuckle sensor 6, the coupler knuckle sensor 6 is not triggered, and the system displays that the coupler is not.
On the contrary, when the coupler knuckle 5 rotates 45 degrees around the coupler knuckle pin in a counterclockwise direction, in the process that the coupler is converted from the full-open position to the locking position, the coupler knuckle 5 drives the fixed seat 16 to rotate synchronously, the fixed seat 16 drives the L-shaped connecting rod 15 to move through the rotating pin 17, under the action of the L-shaped connecting rod 15, the movement of the coupler knuckle 5 is transmitted to the induction shaft 12, the rotation of the coupler knuckle 5 is converted into the linear movement of the induction shaft 12, the induction shaft 12 moves to the rightmost end and leaves the detection range of the coupler knuckle sensor 6, and the coupler knuckle sensor 6 is not triggered.
During the switching of the coupling from the locking position into the fully open position and from the fully open position into the locking position, the sensor shaft 12 moves linearly in the sensor sleeve 13.
The coupler three-state detection logic relationship is as follows:
when the coupler is in the locking position, as shown in fig. 5, since the coupler lock pin 2 is in the locking state, the coupler knuckle 5 is in the locking position, the lower end of the coupler lock pin 2 extends into the detection round hole of the coupler lock pin sensor 10, and the coupler lock pin sensor 10 is triggered to indicate that the coupler is in the locking position.
When the coupler is in the unlocking position, as shown in fig. 6, the coupler pin sensor 10 is not triggered because the coupler pin 2 is lifted, the lower end of the coupler pin 2 is away from the detection area of the coupler pin sensor 10, at the moment, the coupler knuckle 5 does not rotate, the sensing shaft 12 does not move in the sensing shaft sleeve 13 along with the action of the L type connecting rod 15, and the coupler knuckle sensor 6 is not triggered, at the moment, the coupler knuckle sensor 6 and the coupler pin sensor 10 are not triggered, which indicates that the coupler is in the unlocking position.
When the coupler is in the full-open position, as shown in fig. 9, the lower end of the coupler knuckle 2 leaves the detection area of the coupler knuckle sensor 10, and the coupler knuckle sensor 10 is not triggered, at this time, the coupler knuckle 5 rotates for 45 degrees around the coupler knuckle pin 4, the sensing shaft 12 makes a linear motion in the sensing shaft sleeve 13 under the pushing action of the L type connecting rod 15, the sensing shaft 12 extends into the detection range of the coupler knuckle sensor 6, and the coupler knuckle sensor 6 is triggered, so that the coupler is in the full-open position.
Figure 10 is a schematic illustration of a coupling state according to the present invention.
As shown in fig. 10, after the couplers on the first side and the second side are coupled, the couplers on the first side and the second side are both in the locking position, and the mounting brackets 8 mounted on the couplers on the two sides are close to each other and are within the standard distance after the couplers are coupled. The sensor 9 that links that installs at the foremost of installing support 8 is triggered by the installing support 8 of II sides to I side, and II sides, the sensor 9 that links that installs at the foremost of installing support 8 is triggered by the installing support 8 of I side, and the sensor 9 that links that I side, II side are all triggered, show that the coupling accomplishes the action of linking the hook, and link the state well.
