Problems solved by technology

[0003] A very important part of the shunting operation of railway freight cars is to unhook the railway vehicles. Usually, in addition to unhooking the coupler, the unhooking operation of railway freight wagons also needs to unhook the circuit. The circuit is mainly used to connect the wagons. At present, the unhooking of the truck circuit is still in the manual operation stage. When the truck is unhooked, it is necessary for the shunting personnel to drill under the coupler to pick up and open and close the circuits at both ends, which increases the time for the shunting personnel. The workload is heavy, and it is dangerous for the shunting personnel to enter the hook operation, and it also greatly affects the efficiency of the shunting operation

Embodiment 1

[0036] The automatic detachment device for railway wagon circuit of the present invention comprises a fixing device connected with the coupler (such as image 3 shown) and a circuit connection device for connecting wires, such as Figure 8 Schematic diagram of the structure of the circuit connection device shown (hidden fixing device and air duct connection device) and Figure 9 The shown sectional view of the circuit connecting device along the direction of the swing rod (installed in the fixing device), it can be seen that the circuit connecting device includes the electric plug 8 installed in the fixing device 17 and the protective device for protecting the electric plug 8, The protective device leaks out the electric plug 8 automatically by the external force that contacts with the fixing device when the two couplers are connected, and automatically covers the electric plug 8 when the external force disappears. Among them, the electric plug 8 is used to connect the circui...

Embodiment 2

[0049] Compared with Embodiment 1, this embodiment also adds an air passage connection device, which is used to connect air ducts and is installed in a fixing device, and the air passage connection device is located below the circuit connection device (the cross-sectional view of which is shown in figure 2 shown).

[0050] Such as Figure 13 The sectional view of the shown railway wagon circuit automatic pick-and-hook device includes a fixing device 17 connected to the coupler and an air duct connection device for connecting the ventilation pipe. Wherein, the air duct connection device is installed in the fixing device 17, and the fixing device 17 is fixed on the coupler by bolts and moves together with the coupler.

[0051] Fixing device 17 is provided with the first through hole 3 that communicates with air duct, and the structure of fixing device is as follows: image 3 shown.

[0052] The air path connecting device includes a valve stem 5 slidably arranged in the first...

Embodiment 3

[0066] The difference between this embodiment and Embodiment 1 is that the driving device in this embodiment includes a micro switch installed on the fixing device 17, a controller, and a drive rod connected to the controller. The forward and backward movement of the driving rod is controlled, and the driving rod is slidably connected with the swing rod 30 .

[0067] When the coupler is connected, the automatic unhooking devices of the railway wagon circuits on both sides are close to each other. When the contact is made, the micro switch is pressed by the external force of the fixing device, and an open control signal is sent to the controller, and the controller controls the driving rod to move backward. , to drive the swing lever 30 to swing backward, and at the same time, the safety cover 9 swings backward to leak the electric plug 8; One off control signal of device, controller controls drive bar to move forward, drives swing bar 30 to swing forward, and safety cover 9 sw...

Abstract

The present invention provides a railway freight car circuit automatic picking off and coupling up device. The railway freight car circuit automatic picking off and coupling up device comprises a fixing device connected with car couplers and a circuit connecting device used for connecting electric wires, the circuit connecting device comprises an electric plug arranged in the fixing device and a protective device used for protecting the electric plug, and the protective device exposes from the electric plug automatically under the action of the external forces contacted with the fixing device when the two car couplers are coupled up, and covers the electric plug automatically when the external forces disappear.

Description

technical field [0001] The invention relates to the field of railway vehicles, in particular to an automatic detachment device for railway freight car circuits. Background technique [0002] For the railway trucking industry, the dwell time of vehicles at the station accounts for a considerable proportion of the vehicle turnover time. During a turnaround of a truck, it is generally necessary to perform multiple shunting operations. The quality of the shunting operation, the efficiency, and the safety of the shunting operation are not only important for completing the loading and unloading work at the station, shortening the vehicle's residence time, and speeding up the vehicle turnover. Various indicators have a great impact, and are directly related to ensuring traffic safety and realizing train formation plans, train operation diagrams, and transportation schemes. [0003] A very important part of the shunting operation of railway freight cars is to unhook the railway veh...
