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 couplers, the unhooking operation of railway wagons also needs to unhook the air duct. The air duct can transmit wind and use Because of the braking and relief of the train, the current removal and suspension of the railway airway 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 disconnect and open and close the air passage at both ends. It increases the heavy workload for the shunting personnel, 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

[0037] like Figure 13 The shown cross-sectional view of the air-way automatic picking-and-hanging device for railway wagons includes a fixing device 17 connected to the coupler and an air-way connecting 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.

[0038] 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.

[0039] The air path connecting device includes a valve stem 5 slidably arranged in the first through hole 3 for sealing the first through hole 3 and a valve stem spring 7 installed in the first through hole 3, and the valve stem 5 is subjected to an external force to The valve stem spring 7 slides to open the air path, and when the external force disappears, it is automatically reset and closed b...

Embodiment 2

[0051] Compared with Embodiment 1, this embodiment also adds a circuit connection device, which is used to connect the circuit and is installed in the fixing device 17. The circuit connection device is located above the air duct connection device, and its cross-sectional view is as follows figure 2 shown.

[0052] like 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 ...

Embodiment 3

[0067] like Figure 12 As shown, the difference between the present embodiment and the second embodiment is that the inner surface of the sliding groove 10 in the present embodiment is provided with two rows of teeth 31, and the end of the U-shaped bar 12 close to the swing bar 30 is provided with a gear 32, and the gear 32 One side meshes with the tooth 31, and the other side of the tooth 31 leaves a certain gap, so that the tooth 31 can rotate in the sliding groove 10, and the gear 32 is connected to the U-shaped bar 12 in rotation.

[0068] When the coupler is connected, the U-shaped bar 12 overcomes the force of the back-moving spring 18 and moves backwards, driving the gear 32 to rotate backwards, the swing lever 30 swings backwards, and drives the safety cover 9 to swing backwards and leak the electric plug, and the electric plugs on both sides are connected to each other. Docking connects the circuit; when the coupler is removed, the U-shaped bar 12 is moved forward by ...

Abstract

The present invention provides a railway freight car wind path automatic picking off and coupling up device. The railway freight car wind path automatic picking off and coupling up device comprises a fixing device connected with car couplers and a wind path connecting device arranged in the fixing device, and the wind path connecting device is connected with the air ducts, connects the wind paths automatically under the action of the external forces contacted with the fixing device when the two car couplers are coupled up and blocks the wind paths automatically when the external forces disappear. The railway freight car wind path automatic picking off and coupling up device of the present invention can realize the automatic picking off and the coupling up of the railway freight car wind paths, enables the picking off and the coupling up work time to be shortened, the labor cost to be saved and the shunting efficiency of the operating personnel to be improved.

Description

technical field [0001] The invention relates to the field of railway vehicles, in particular to an automatic detachment device for air passages of railway freight cars. 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 wagons is to unhook the railway v...
