Background
The No. 13 coupler is a coupler commonly used in railway trucks and electric and diesel locomotives, and mainly comprises a coupler body 1, a coupler knuckle 2 and a coupler knuckle pin 3, wherein one side of the coupler body 1 is an ㄈ -shaped structure 11 (shown in FIGS. 3 and 4), the upper end and the lower end of the ㄈ -shaped structure 11 are provided with through holes 111, and the opposite inner sides of the upper end and the lower end of the ㄈ -shaped structure 11 are provided with pin guards 112; the coupler knuckle 2 is arranged at a notch at the upper end and the lower end of the ㄈ -shaped structure 11 (as shown in fig. 1 and 5), a through hole 21 is arranged on the coupler knuckle 2 corresponding to the through hole 111 (as shown in fig. 6 and 7), and the coupler body 1 and the coupler knuckle 2 are pivoted together after the coupler knuckle pin 3 passes through the through hole 111 and the through hole 21; the contact part of the knuckle 2 and the upper end part and the lower end part of the ㄈ -shaped structure 11 is provided with a pin protection socket 22 matched with the pin protection table 112. The No. 13 coupler is in three states in use, namely three states for short; the first state is the fully opened coupler knuckle, which is kept at an accurate position to be connected, at the moment, the coupler knuckle 2 is positioned by the coupler knuckle pin 3, the smaller the gap between the coupler knuckle pin and the coupler body and the coupler knuckle is, the more accurate the coupler knuckle position is, and the safer the connection is. The second state is a closed coupler knuckle state, in which the coupler knuckle is completely locked and is in a traction force state, in which the annular wall 221 of the pin protecting socket 22 of the coupler knuckle 2 and the pin protecting table 112 of the coupler body 1 are in contact with each other to transmit traction force (as shown in fig. 5), and the coupler knuckle pin 3 should not be stressed. The third state is unlocked (irrelevant to the present invention, no further description is given).
In the prior art, a steel sleeve 4 is arranged between the coupler body 1 and the coupler knuckle pin 3 (as shown in fig. 5); however, the steel elasticity is poor, the steel sleeve 4 has no deformability, and if the gap is too large, the opening position of the coupler knuckle is inaccurate when the No. 13 coupler is in the first state, so that the coupling safety is affected; if the clearance is too small, the latch pin will be forced to bend when the 13 th coupler is in the second state. In the prior art, the clearance between the pin guard 112 and the pin guard socket 22 is often larger than the clearance between the steel sleeve 4 and the latch pin 3, so that the latch pin 3 is forced to bend.
The problems are not solved well for a long time, so that a great amount of bent latch pins are arranged on the whole road every year, the loss caused by the bent latch pins is huge, and the severely bent latch pins are blocked in the latches and cannot be taken out, so that the coupler can be scrapped. Therefore, there is a need to solve the problem of bending of the latch pin.
