[0037] Based on the above structure, the telescopic rod of gas spring 4 is in contact with the piston rod of locking latch oil cylinder 9, so that the action process of the telescopic rod of gas spring 4 can reflect the action process of the piston rod of locking latch oil cylinder 9. Although locking latch oil cylinder 9 cannot be installed with built-in stroke sensor and the piston rod is arranged in the equipment interior and cannot be detected by conventional method, the position of the piston rod of locking latch oil cylinder 9 can be reflected by the position of the telescopic rod of gas spring 4, that is, the telescopic rod of gas spring 4 can be detected at a special position, so as to reflect the upper limit position and the lower end limit position of the piston rod of locking latch oil cylinder 9. The upper limit position is the position where locking latch oil cylinder 9 retreats to the position and locking latch oil cylinder 9 separates from steel wire rope head 10, and the truss can be lifted and operated alone without steel wire rope. The lower end limit position is the position where locking latch oil cylinder 9 pushes out to the position and locking latch oil cylinder 9 is connected with steel wire rope head 10, and the truss can be lifted and operated with steel wire rope through locking latch oil cylinder 9 connecting steel wire rope head 10. The telescopic rod of gas spring 4 penetrates through the steel plate of ship compartment deck layer steel wire rope head groove 110 and contacts the piston rod of locking latch oil cylinder 9 in the interior of steel wire rope head 10.

The reinforcing rib 13 is arranged between the support horizontal plate 12 and the support vertical plate 11.

[0040] Based on the above structure, since the support horizontal plate 12 is arranged at the lower end of the side wall of the support vertical plate 11, a larger assembly space can be provided for other components at the upper end of the support horizontal plate 12. Meanwhile, the reinforcing rib 13 arranged between the support horizontal plate 12 and the support vertical plate 11 can increase the stability of the entire device.

The fixed inner plate 21 and the fixed outer plate 22 are connected as a whole by means of a countersunk bolt.

[0042] The fixed outer plate 22 can be arranged at the center of the fixed inner plate 21. The fixed inner plate 21 is provided with a first arc-shaped through slot 23. The fixed outer plate 22 is provided with a second arc-shaped through slot 24 at a corresponding position, which matches the first arc-shaped through slot 23. The first arc-shaped through slot 23 and the second arc-shaped through slot 24 combine to form a circular through slot, which is matched with the circular base of the gas spring 4. The base of the gas spring 4 is arranged in the circular through slot formed by the first arc-shaped through slot 23 and the second arc-shaped through slot 24.

[0043] Based on the above structure, by arranging arc-shaped through slots in the fixed outer plate 22 and the fixed inner plate 21, the position of the gas spring 4 can be fixed. After being fixed, the end of the base of the gas spring 4 is in contact with the support horizontal plate 12, that is, the circular through slot accurately fixes the position of the gas spring 4, so that it remains vertical at the predetermined position, thereby ensuring the accuracy of the position of the telescopic rod of the gas spring 4.

[0044] As an example, the guide part 3 can include a fixed plate 31 and a trapezoidal slot 32. The fixed plate 31 is arranged on the support vertical plate 11 by means of a countersunk bolt.

[0047] As an example, the trigger piece can be a first sensing plate 71 and a second sensing plate 72, both of which are L-shaped metal plates, and both of which can include a connecting vertical plate 711 and a sensing horizontal plate 712; the connecting vertical plate 711 and the sensing horizontal plate 712 are arranged vertically, and a through hole is arranged on the connecting vertical plate 711, and the connecting vertical plate 711 is connected with the side wall of the square body 52 through a bolt.

[0048] The first sensing plate 71 and the second sensing plate 72 are arranged on both sides of the square body 52 respectively, and the first sensing plate 71 and the second sensing plate 72 are arranged reversely, that is, the first sensing plate 71 and the second sensing plate 72 are arranged in central symmetry along the center of the square body 52.

[0049] Based on the above structure, by reversely arranging the first sensing plate and the second sensing plate, other components inside can be avoided, so that the whole triggering process is more efficient.

[0050] As an example, the sensing part can include a first sensor mounting sheet 61 and a second sensor mounting sheet 62; the first sensor mounting sheet 61 and the second sensor mounting sheet 62 are similar in structure, and the first sensor mounting sheet 61 is taken as an example, the first sensor mounting sheet 61 is T-shaped as a whole, the tail is straightly bent at right angles and is provided with a threaded hole, which is used for mounting the first sensor mounting sheet 61 on the supporting vertical plate 11; two sensors are arranged in parallel on the first sensor mounting sheet 61, and the direction of the sensor matches the position of the first sensing plate 71;

[0051] Similarly, the direction of the sensor on the second sensor mounting sheet 62 matches the position of the second sensing plate.

[0052] Based on the above structure, when the truss needs to be lifted alone and the steel wire rope needs to cross the water area of the ship compartment to prevent collision, the piston rod of the lock latch oil cylinder 9 is withdrawn upward, the gas spring 4 is pushed upward by the restoring force of itself, the sliding block 5 is pushed upward by the gas spring 4, and the telescopic rod is pushed upward by the sliding block 5; when the first sensor sensing sheet on the right side approaches the sensor on the right side and makes the sensor send a signal to withdraw to the position, the system controls the piston rod of the lock latch oil cylinder 9 to stop withdrawing, at this time, the lock latch oil cylinder 9 withdraws to the position, the lock latch oil cylinder 9 is separated from the steel wire rope head 10, and the truss can be lifted alone without the steel wire rope;

[0053] When the truss needs to be lifted with the steel wire rope, the piston rod of the lock latch oil cylinder 9 is pushed out downward, the telescopic rod is pushed downward by the piston rod, the sliding block 5 is pushed downward by the telescopic rod, and the gas spring 4 is compressed downward by the sliding block 5; when the second sensor sensing sheet on the left side approaches the sensor on the left side and makes the sensor send a signal to push out to the position, the system controls the piston rod of the lock latch oil cylinder 9 to stop pushing out, at this time, the lock latch oil cylinder 9 pushes out to the position, the lock latch oil cylinder 9 is connected with the steel wire rope head 10, and the truss can be lifted with the steel wire rope through the connection of the lock latch oil cylinder 9 and the steel wire rope head 10.

[0056] Embodiment 2

[0057] Based on the structure of the above embodiment 1, the utility model provides a technical scheme:

[0058] A signal detection method for a ship lock chamber anti-collision lock latch oil cylinder 9, when the truss needs to be lifted alone and the steel wire rope needs to cross the water area of the ship compartment to prevent collision, the piston rod of the lock latch oil cylinder 9 is withdrawn upward, the gas spring 4 is pushed upward by the restoring force of itself, the sliding block 5 is pushed upward by the gas spring 4, and the telescopic rod is pushed upward by the sliding block 5; when the first sensor sensing sheet on the right side approaches the sensor on the right side and makes the sensor send a signal to withdraw to the position, the system controls the piston rod of the lock latch oil cylinder 9 to stop withdrawing, at this time, the lock latch oil cylinder 9 withdraws to the position, the lock latch oil cylinder 9 is separated from the steel wire rope head 10, and the truss can be lifted alone without the steel wire rope;

[0060] When the locking cylinder 9 is pushed out, the piston rod pushes the telescopic rod and the sliding block 5 downward to compress the gas spring 4; when the locking cylinder 9 is retracted, the gas spring 4 pushes the sliding block 5 and the telescopic rod upward to reset under the action of the elastic force of the gas spring 4. Accordingly, the sliding block 5 accurately tracks the position of the piston rod of the locking cylinder 9, so that the position of the piston rod of the locking cylinder 9 is detected by detecting the position of the sliding block 5.
