Technical Field

The invention belongs to the technical field of vehicle braking, and particularly relates to an automatic release pull rod mechanism.

Background

The manual releasing handle of the anti-slip device is in a vertical downward automatic anti-slip state under the normal working state of the anti-slip device, and the manual releasing handle of the anti-slip device mainly has the function that the anti-slip device is manually operated in an abnormal state to manually release the automatic anti-slip device of the vehicle and is used for emergency releasing of the anti-slip device under the abnormal working condition of the vehicle or the train.

The anti-slip device relieving device is arranged on the anti-slip device body, the locking body needs to be manually pushed, and the automatic anti-slip state of the anti-slip device can be relieved after the relieving handle is rotated. Because different vehicle models have different structures, for the models of railway vehicles, such as C70, C80B, C64 and the like, in which a brake cylinder and a connecting rod system are arranged at the bottom of a main beam of the railway vehicle, after the anti-slide device is installed, if the anti-slide device needs to be manually released, an operator needs to drill into the bottom of the vehicle to operate the anti-slide device, and great inconvenience and potential safety hazards are brought to the self safety and the driving safety of the operator.
