Problems solved by technology

[0003] A very important part of the shunting operation of railway wagons 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 and circuit. The air duct can transmit the wind. , used for braking and relief of the train, the circuit is used to connect the electrical connection between the two carriages, and currently the detachment of the railway airway and the circuit is still in the manual operation stage. When the truck is detachment, it needs The shunting personnel drilled under the coupler to pick up and open and close the air ducts and circuits at both ends, which increased the heavy workload for the shunting personnel, and it was also dangerous for the shunting personnel to enter the coupler for work, and it also greatly affected Shunting efficiency

Embodiment 1

[0039] figure 2 It is a cross-sectional view of the automatic picking-and-hanging device for railway wagons in the detached state, including a fixing device 17 connected with the coupler, an air-way connecting device for connecting the ventilation pipe, and a circuit connecting device for connecting the circuit. Wherein, both the air duct connecting device and the circuit connecting device are installed in the fixing device 17, and the fixing device 17 is fixed on the coupler by bolts and moves together with the coupler. Preferably, the air duct connecting device is installed under the circuit connecting device.

[0040] Wherein, the upper part of the fixing device 17 is provided with a rectangular groove for installing the circuit connection device, and the lower part is provided with the first through hole 3 communicating with the air duct. The structure of the fixing device is as follows: image 3 shown.

[0041] Wherein, the air path connection device includes a valve st...

Embodiment 2

[0066] like Figure 12As shown, the difference between the present embodiment and the first 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.

[0067] When the coupler is connected, the U-shaped bar 12 overcomes the force of the return spring 18 and moves backward, driving the gear 32 to rotate backward, the swing lever 30 swings backward, and drives the safety cover 9 to swing backward to leak out of the electrical connection joint. The joints are butted with each other to connect the circuit; when the coupler is removed, the U-shaped bar 12 is moved forward by the force of the return s...

Embodiment 3

[0070] 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 .

[0071] When the coupler is connected, the automatic unhooking devices of railway freight cars 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. The controller controls the driving rod to move backward. Drive the swing rod 30 to swing backward, and at the same time, the safety cover 9 swings backward to leak out the electrical connection joint 8; when the coupler is removed, the automatic removal and hanging devices of the railway freight cars on both sides are far away from each othe...

Abstract

The invention provides an automatic unhooking device for railway wagons, which includes a fixing device installed on the coupler; an air passage connecting device connected with the air duct, automatically opens the air passage when the two couplers are connected, and automatically closes when the external force disappears Air circuit; circuit connection device, including electrical connection joints and protection units for isolating electrical connection joints. When the two couplers are connected, the protection unit is opened by the external force contacted by the fixing device, and the electrical connection joints are connected to power. When the external force disappears , the electrical connection joint is disconnected, and the protection unit resets to isolate the electrical connection joint; the air circuit connection device and the circuit connection device are installed in the fixing device. The invention can realize the automatic detachment and hanging of the air duct and circuit of the railway freight car, shorten the working time of detachment and hanging, and save labor cost.

Description

technical field [0001] The invention relates to the field of railway vehicles, in particular to an automatic unhanging device for 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 vehicles. Usually,...
