9. The ship car anti-collision latch cylinder signal detection device of the ship is characterized in that the sensing part comprises a first sensor mounting plate and a second sensor mounting plate, the first sensor mounting plate and the second sensor mounting plate are identical in structure, the whole first sensor mounting plate is T-shaped, the tail of the first sensor mounting plate is bent at right angles and is provided with a threaded hole for mounting the first sensor mounting plate on a supporting vertical plate, two sensors are arranged on the first sensor mounting plate in parallel, and the direction of each sensor is matched with the position of the first sensing plate.
10. A detection method based on the ship car anti-collision latch oil cylinder signal detection device of the ship car anti-collision latch oil cylinder detection device of the ship car is characterized in that when a truss is required to be lifted independently and a steel wire rope stretches across a ship car water area to play an anti-collision protection role, a piston rod of the latch oil cylinder is retracted upwards, a gas spring pushes a sliding block upwards under the action of self elastic force recovery, and the sliding block pushes a telescopic rod upwards;
When the second sensor sensing piece on the left side is close to the sensor on the left side and enables the sensor to send out a push-out in-place signal, the system controls the piston rod of the latch oil cylinder to stop pushing out and running, at the moment, the latch oil cylinder is pushed out and in place, the latch oil cylinder is connected with a wire rope hanging head, and the truss can carry out lifting and running with the wire rope through the connection of the latch oil cylinder and the wire rope hanging head;
When the latch oil cylinder is pushed out, the piston rod pushes the telescopic rod and the sliding block to compress the gas spring downwards, and when the latch oil cylinder is retracted, the gas spring pushes the sliding block and the telescopic rod to reset under the action of self elasticity. Therefore, the accurate tracking of the sliding block to the position of the piston rod of the latch oil cylinder is realized, and the purpose of detecting the position of the piston rod of the latch oil cylinder is achieved by detecting the position of the sliding block.
