The rack 3 is fixed along the running direction of the track 2 and laid on the inner wall of the track 2. The clamping block 4 is fixedly connected to the rotating cylinder 14. The torsion spring 13 is sleeved on the rotating cylinder 14. Two clamping teeth are fixedly arranged on the clamping block 4. The two clamping teeth are symmetrically arranged with respect to the support shaft 12. Both of the two clamping teeth are in contact clamping limit fit with the teeth on the rack 3. One end of the torsion spring 13 is fixedly connected to the clamping block 4, and the other end is fixedly connected to the sliding seat 8.

[0031] A braking release and limiting component is installed on the grip 5. The braking release and limiting component is in limit fit with the support shaft 12 and is used to limit the rotation of the rotating cylinder 14 when the braking is released.

[0032] The braking release and limiting component includes a plug rod 9. A sliding through hole is opened in the grip 5 along the radial direction of the rotating cylinder 14. The sliding through hole extends to the rotating block 6 and the rotating cylinder 14 in sequence. The plug rod 9 penetrates into the sliding through hole and is in sliding fit with the grip 5, the rotating block 6 and the rotating cylinder 14. A limiting hole corresponding to the sliding through hole is opened on the support shaft 12. The plug rod 9 is in plugging limit fit with the limiting hole.

[0033] The plug rod 9 penetrates out of the grip 5 along the direction of the grip 5 far from the rotating block 6. The thumb of the human body is in abutting transmission fit with the grip 5. A relief groove 10 is opened in the grip 5. The relief groove 10 is communicated with the sliding through hole. A transmission ring is fixedly sleeved on the plug rod 9. The transmission ring is slidably arranged in the relief groove 10. A spring 11 is arranged in the relief groove 10. The spring 11 is sleeved on the plug rod 9. One end of the spring 11 is fixedly connected to the transmission ring, and the other end is fixedly connected to the grip 5.

[0034] In this embodiment, the cross-section of the track 2 is in a shape of Chinese character 'tu'. The sliding seat 8 is located in the horizontal bar corresponding to the lower horizontal bar of the Chinese character 'tu'. The sliding seat 8 is a square block and is in limit sliding fit with the guide rail 1. It is ensured that the sliding seat 8 only slides along the track 2.

[0035] Support shaft 12, rotating drum 14 and torsion spring 13 are located in the corresponding T-shaped horizontal channel, support shaft 12 is perpendicular to sliding seat 8 and penetrates guide rail 1 along the corresponding horizontal channel. It ensures that support shaft 12 and rotating drum 14 move along guide rail 2.

[0036] Card block 4 and rack 3 are located in the corresponding T-shaped horizontal channel above, rack 3 is laid on the side wall of the corresponding horizontal channel.

[0037] Rotating drum 14 is installed with guide block 7 in the horizontal channel, rotating drum 14 and support shaft 12 penetrate guide block 7; guide block 7 is connected with rotating drum 14, guide block 7 is located between rotating block 6 and card block 4 and is limited to slide with guide rail 1.

[0038] In this embodiment, the end of rotating block 6 close to sliding seat 8 is in sliding contact with guide rail 1.

[0039] Working principle: when the crew uses the safety protection device, the handle 5 is turned obliquely upward, and at the same time the thumb presses the insertion rod 9. When the handle 5 rotates, it drives the rotating block 6 and the insertion rod 9 to rotate synchronously, and the rotating block 6 drives the rotating drum 14 to rotate synchronously. When the sliding hole and the limiting hole are in communication, the thumb pushes the insertion rod 9 to slide into the limiting hole, and in this process, the transmission ring on the insertion rod 9 compresses the spring 11. Then, keep the thumb pressing force on the insertion rod 9.

[0040] When the rotating drum 14 rotates, it drives the card block 4 to rotate. The card block 4 located below the card teeth is disengaged with the teeth on the rack 3, and at the same time the torsion spring 13 is twisted. After the insertion rod 9 is inserted into the limiting hole, the rotating drum 14 stops rotating.

[0041] Then the crew goes down the gangway, pushes the handle 5 obliquely downward, and the handle 5 drives the rotating block 6 and the insertion rod 9 to move synchronously. The rotating block 6 drives the rotating drum 14 to move synchronously, and the rotating drum 14 and the insertion rod 9 drive the support shaft 12 to move synchronously. The support shaft 12 drives the sliding seat 8 to slide obliquely downward along the guide rail 2.

[0042] When an emergency occurs, the crew's thumb releases the insertion rod 9. At this time, the spring 11 is elongated and pushes the transmission ring to slide away from the support shaft 12. The transmission ring drives the insertion rod 9 to slide out of the limiting hole, and the rotating drum 14 can rotate freely.

[0043] If the crew's body tilts downward at this time, the crew's hand holds the handle 5 tightly and pushes the handle 5 obliquely downward. At this time, the handle 5 drives the rotating block 6 to rotate, and the rotating block 6 drives the rotating drum 14 to rotate. The rotating drum 14 drives the card block 4 to rotate, and the card block 4 located below the card teeth is engaged with the teeth on the rack 3. Thus, the rotation and oblique downward movement of the rotating drum 14 are stopped, and the rotating drum 14 prevents the support shaft 12 from moving obliquely downward, and the support shaft 12 prevents the sliding seat 8 from sliding obliquely downward. At the same time, the rotating drum 14 prevents the rotating block 6 from sliding obliquely downward, and the rotating block 6 prevents the handle 5 from sliding obliquely downward. Thus, the crew can prevent falling down.

[0044] If the crew lies back at this time, the hands of the crew hold the handle 5 tightly and pull the handle 5 obliquely upwards, and the handle 5 drives the rotating block 6 to rotate, and the rotating block 6 drives the rotating drum 14 to rotate. The rotating drum 14 drives the clamping block 4 to rotate, and the clamping block 4 is clamped with the teeth on the rack 3. Thus, the rotating drum 14 is stopped from rotating and moving obliquely upwards, and the rotating drum 14 prevents the support shaft 12 from moving obliquely upwards, and the support shaft 12 prevents the sliding seat 8 from sliding obliquely upwards. At the same time, the rotating drum 14 prevents the rotating block 6 from sliding obliquely upwards, and the rotating block 6 prevents the handle 5 from sliding obliquely upwards. Thus, the crew can prevent from lying back upwards.

[0045] When the crew does not use the safety protection device, the torsion spring 13 applies a torsion force to the clamping block 4, and the clamping block 4 is clamped with the teeth on the rack 3 at the lower part, so as to prevent the sliding seat 8 from sliding downwards.

[0046] Finally, it should be noted that the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
