[0022] like Figure 1 to Figure 2 As shown,

[0023] The adjustable guardrail for transport ships comprises a plurality of groups of railings connected together, a cross bar is arranged between two adjacent railings, the railings comprise a main guardrail 1 and a base 2, a controller is arranged on the outer wall of the main guardrail 1, and the controller is electrically connected to a hydraulic cylinder 4, a stepper motor 13 and a drive motor 9.

[0024] An installation groove 3 is provided on the upper end surface of the base 2, and a hydraulic cylinder 4 is arranged in the installation groove 3. The output end of the hydraulic cylinder 4 is connected to the lower end surface of the main guardrail 1. The main guardrail 1 is connected to a protective plate 5 for catching objects dropped by the crew.

[0025] A slide groove 6 is provided on the side wall of the main guardrail 1 , and a moving component is provided in the slide groove 6 for realizing the lifting and lowering of the protective plate 5 .

[0026] The moving assembly includes a ball screw 7, a fixed seat 8, a drive motor 9 and a slide 10. The fixed seat 8 and the drive motor 9 are placed at both ends of the slide groove 6, the ball screw 7 is placed between the fixed seat 8 and the drive motor 9, the slide 10 is sleeved on the outer peripheral wall of the ball screw 7, two protrusions are provided on the protective plate 5, and a mounting block is threadedly connected to the slide 10. A slot for the protrusion to be embedded is provided at the other end of the mounting block. The protrusion is rotatably connected to the mounting block. The hinge connection between the slide 10 and the protective plate 5 is realized through the rotational connection between the protrusion and the mounting block, so that the protective plate 5 can be tilted when the pull rope 11 is pulled, which facilitates the sliding of fallen objects and the crew to take out the fallen objects.

[0027] A pull rope 11 is provided on the upper end surface of the protective plate 5 , and a pulling piece is connected to the other end of the pull rope 11 . A placement groove 12 for placing the pulling piece is opened on the side wall of the main guardrail 1 .

[0028] The pulling member includes a stepper motor 13 placed in a placement groove 12 and a wire wheel 14 placed at the output end of the stepper motor 13. The wire wheel 14 is sleeved on the output end of the stepper motor 13, and the wire wheel 14 is fixed to the output end of the stepper motor 13 by screws. The other end of the pull rope 11 is fixedly connected to the wire wheel 14. The stepper motor 13 rotates to realize the contraction and release of the pull rope 11, thereby realizing the adjustment of the inclination angle of the protective plate 5.

[0029] A support frame 15 for supporting the pull rope 11 is provided on one side of the stepper motor 13. The support frame 15 includes a main body 16 and a roller body 17 rotatably connected to the main body 16. The outer wall of the pull rope 11 is placed on the roller body 17. The main body 16 is screwed to the inner wall of the placement groove 12. The pull rope 11 is supported by the support frame 15, which reduces the wear of the pull rope 11 during the pulling process. Furthermore, the pull rope 11 contacts the outer wall of the rotatable roller body 17, and the sliding friction is converted into rolling friction during the pulling process, which further extends the service life of the pull rope 11.

[0030] Working principle: when the transport ship is running, the protective plate 5 is moved to the lowermost end of the screw rod by rotating the driving motor 9, and then the pull rope 11 is unscrewed by the stepper motor 13 to make the protective plate 5 parallel to the horizontal plane. When the crew is sightseeing next to the main guardrail 1, the crew's belongings fall, and the fallen objects will be caught by the protective plate 5 connected to the main guardrail 1 to prevent the objects from falling into the water. When the objects fall on the protective plate 5, the driving motor 9 is started by the controller, and the driving motor 9 drives the ball screw 7 to rotate. At this time, the slide 10 is displaced, driving the protective plate 5 to displace. When the protective plate 5 moves to a suitable height, the pull rope 11 is tightened by driving the stepper motor 13. At this time, the protective plate 5 tilts under the action of tension, so that the fallen objects slide to a place where the crew can reach them. After taking them, repeat the above operation to restore the protective plate 5.

[0031] When the height of the main guardrail 1 needs to be adjusted, it is only necessary to start the hydraulic cylinder 4 .

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
