Description

Technical Field

[0001] The utility model belongs to the technical field of railway vehicles, and in particular relates to an anti-hook jumping device and a coupler device thereof. Background Art

[0002] The subway vehicles are connected to each other through the coupler device, which cushions and transmits the impact of the vehicles during driving and keeps a certain distance between the vehicles. The coupler device is extremely important and is divided into "upper-acting coupler device" and "lower-acting coupler device" according to the opening method. At present, Guangzhou Metro mostly uses "upper-acting coupler device" opened by the hook lifting device. During maintenance and connection operations, the "upper-acting coupler device" needs to rely on the hook lifting device to switch the coupler device between the unlocked, locked and fully opened states; the hook lifting device includes a lower locking pin device, which has a large mass. In order to make it easier to operate the hook lifting device, the long rod principle is adopted during design. Therefore, the coupler device is unlocked by gently lifting the handle of the hook lifting device.

[0003] The coupler device is located at both ends of the vehicle body, and the hook lifting device is set next to the vehicle body, which poses a certain risk of human misoperation. In addition, when the vehicle is driving, operating, and towing in a coupled state, it is subject to large irregular frequency vibrations from the track. The coupler device is located at the end and is prone to generate large jumping forces, which poses a risk of the lower locking pin device jumping. Under abnormal conditions, the unlocking of the coupler device will lead to extremely serious consequences. For example, the electric passenger car will immediately lose control if the coupler device is abnormally unlocked during shunting operations. At present, in order to prevent the locking pin of the coupler device from jumping, the vehicle will use wire to tie the hook pin lock when leaving the vehicle. This solution has poor stability and needs to be re-tied after each maintenance and unhooking. There is a problem of low efficiency in tying and restoring. At the same time, due to the need for multiple "tie-untie-tie" maintenance, it is also easy to lose materials in the process. At present, there is a lack of a reliable and durable anti-hooking device to improve the coupling stability of the coupler device and prevent the lower locking pin device of the coupler device from jumping off under abnormal conditions.

[0004] Therefore, a new technology is needed to solve the problem of lacking a reliable and durable anti-hook jumping device in the prior art. Utility Model Content
