Embodiment Construction

[0025] The specific implementation of the automatic dehook mechanism will be further described below with reference to the accompanying drawings.

[0026] figure 1 It is a working principle diagram of the decoupling mechanism, including: a front compartment coupler body 1, a coupler arm 2, a rear compartment coupler body 4, and a ground slope device 5.

[0027] An automatic unhooking mechanism for railway wagons, such as figure 2 , the mechanism includes: a pole assembly 6, an installation sleeve assembly 9, a roller assembly 11, a ground slope device 5, and a positioning pin 8.

[0028] The lower transmission sleeve 10 of the roller assembly 11 is sleeved in the support sleeve 12 of the installation sleeve assembly 9 .

[0029] The upper transmission sleeve 7 of the rod assembly is set in the lower transmission sleeve 10 of the roller assembly, and the positioning pin 8 is inserted into the positioning hole a or b of the two for positioning, and one of the positioning hole...

Abstract

The present invention is automatic decoupling mechanism for railway freight car, and automatic decoupling mechanism is especially suitable for decoupling No. 13 standard coupler. The automatic decoupling mechanism has roller assembly with lower driving sleeve, installation sleeve assembly with support sleeve, lever poking assembly with upper driving sleeve, hook lifting rod inside the coupler, locating chain inserted inside the locating sleeve to limit the portion of the automatic decoupling mechanism and realize the coupling between the mechanism and the coupler, and ramp device installed on the ground the railway freight car pass through. During decoupling operation, the coupler ring is lifted automatically while the roller assembly is made to move upwards by the hump so as to decouple.

Description

technical field [0001] The invention relates to an automatic decoupling mechanism for railway wagons, in particular to an automatic decoupling mechanism for No. 13 standard couplers. Background technique [0002] At present, there are 49 marshalling yards in China's railway network. In the daily work of marshalling yards, uncoupling freight trains is the basis for train reorganization. The coupler is a vehicle component used to realize the connection between the locomotive and the vehicle or between the vehicle and the vehicle, transmit traction and impact force, and keep a certain distance between the vehicles. Most of the truck couplers in use now are No. 13 standard couplers stipulated by the Ministry of Railways of China in 1965. [0003] At present, China's marshalling stations use manual operations for uncoupling freight trains. In this case, it not only consumes a lot of manpower and material resources, but also affects the efficiency of train remarshalling. [0004...
