Embodiment Construction
[0029] In conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
[0030] like figure 1 As shown in the schematic diagram of the coupler connection, the connection between the coupler 5 and the knuckle of another coupler is realized through an adapter frame. The adapter frame includes an integrally formed horizontal part 3 and two connecting plates 2, and the two connecting plates 2 are respectively vertically arranged At both ends of the transverse part 3, the top ends of the connecting plate 2 are respectively equipped with trunnions 4 for connecting the coupler knuckle 11. The two trunnions 4 are coaxially arranged and can rotate freely relative to the knuckle 11, and the trunnions 4 can be moved along the The axial movement realizes the connection and disengagement with the knuckle 11. An automatic fall-off prevention mechanism 12 is also connected between the knuckle 11 and the trunnion 4, and the automatic fall-off ...

The invention belongs to the field of car coupler switching devices. In order to effectively solve the problems of loosening, falling and others, a falling-prevention car coupler switching device usedfor a switch engine is provided. An automatic falling-prevention mechanism is connected between lug shafts of a switching frame and a coupler knuckle and comprises a fixed shell installed on the coupler knuckle, an embedding and pressing starting mechanisms, an electromagnetic connection mechanism, gear transmission mechanisms and a power connection box, wherein the embedding and pressing starting mechanism executes embedded connection with the lug shafts; the embedding and pressing starting mechanism and the lug shafts are attracted and locked through the electromagnetic connection mechanism, the electromagnetic connection mechanism is controlled to be powered on or off through the gear transmission mechanisms, and the power connection box controls power connection mechanisms to be powered on or off. Based on the principle that powering generates a magnetic field, the lug shafts of the switching frame can be tightly attracted and locked through the automatic falling-prevention mechanism, the problems of loosening and falling when the car coupler switching device is connected with a car coupler are solved, and therefore using safety is improved; meanwhile, when the car coupler needs to be separated, a switching-off button is pressed, and the car coupler switching device and the car coupler are convenient to install and detach.
Description
technical field [0001] The invention belongs to the field of coupler adapters, and in particular relates to a detachment-preventing coupler adapter for shunting locomotives and a control method for coupler detachment prevention. Background technique [0002] Shunting locomotives refer to locomotives used for shunting operations such as train marshalling, dismantling, line transfer, and vehicle pickup and delivery. The work is characterized by frequent starts and stops. [0003] The shunting locomotive is the basic driving force of the shunting work, and its technical requirements are different from those of the general locomotive that pulls trains. Since it is necessary to start traction or push the vehicle group in a short distance, it does not need a high construction speed, but it needs a certain amount of traction. Since it needs to move forward or backward frequently, it requires good lookout conditions. Since it mainly works in the station, It is necessary to pass th...
