Problems solved by technology
In this regard, the current solution is to change the internal clearance size of the locomotive coupler box to reduce the amount of runout. However, this method has the disadvantage that the amount of runout reduction is limited, and it can only reduce the probability of accidents to a certain extent, but cannot effectively prevent them.
In addition, another existing solution is to replace the improved locomotive coupler with its own anti-detachment device. However, this solution has the disadvantage that improving the coupler requires long-term verification and cannot be implemented in a short period of time. So far, no new coupler has been successfully developed, and even Being able to replace new couplers also has the problems of high cost and heavy workload for batch replacement of active couplers

The present invention proposes a coupler detachment prevention device and a rail vehicle. The coupler detachment detachment device includes a body and a mounting plate; the body has a first section and a second section connected along a first direction, and the first section is passed through a container through a first opening. The cavity is exposed from the second opening, the first section is connected to the first coupler, and the second section is accommodated in the accommodating part; the mounting plate is detachably fixed on the part of the first section exposed to the second opening, and the mounting plate The size is larger than the size of the second opening to limit the body and the first coupler in a second direction perpendicular to the first direction. Through the above design, the coupler detachment prevention device proposed by the present invention can realize the functions of anti-decoupling and anti-jumping of the two couplers in the vertical direction without changing the original structure of the coupler. Moreover, the present invention can be installed without buckling the car, can realize quick disassembly and assembly suitable for various scenarios, is convenient and flexible, and does not produce any side effects.
Description
technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a coupler anti-detachment device and a rail vehicle. Background technique [0002] Existing rail vehicles, especially rail vehicles including locomotives and freight cars, have the problem of decoupling caused by the jumping up of the locomotive coupler during heavy-load transportation. In this regard, the current solution is to change the internal clearance size of the locomotive coupler box to reduce the amount of runout. However, this method has the disadvantage that the amount of runout reduction is limited, and it can only reduce the probability of accidents to a certain extent, but cannot effectively prevent them. In addition, another existing solution is to replace the improved locomotive coupler with its own anti-detachment device. However, this solution has the disadvantage that improving the coupler requires long-term verification and cannot be implemented in a sh...
