Abstract

The invention provides an automatic unhooking device and an automatic unhooking method. The automatic unhooking device comprises: a mechanical hook head which is internally provided with a coupler knuckle plate capable of pivoting; a driving unit used for driving the coupler knuckle plate to rotate; and an uncoupling in-place signal detection unit used for detecting whether the coupler knuckle plate rotates to an uncoupling position or not and sending an uncoupling in-place signal when detecting that the coupler knuckle plate rotates to the uncoupling position. According to the automatic unhooking device and the automatic unhooking method, automatic unhooking and unhooking operations can be realized in a high-speed running state, so that two vehicles coupled with the device are separated,and the safety of test equipment and personnel is guaranteed.

Description

technical field [0001] The invention belongs to the field of vehicle collision tests, in particular to an automatic decoupling device and an automatic decoupling method. Background technique [0002] The coupler device mainly plays the role of coupling the vehicle and transmitting the longitudinal force. The traditional coupler buffer device is mainly designed around how to improve the reliability of the coupling and prevent the occurrence of automatic uncoupling accidents. However, with the development of the economy and society, the demand for coupler functions is more diverse. In some industrial application scenarios, such as vehicle crash test systems and molten iron car unloading, it is necessary to realize automatic uncoupling between the tractor and the towed vehicle. Hook, unhook function. [0003] The vehicle crash test system needs to use a driving vehicle to pull the tested vehicle to accelerate to the target speed and then perform decoupling control. After decou...
