Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of gangways, and particularly relates to a rope-penetrating pilot gangway. BACKGROUND

[0002] A gangway is a lifeline device used on ships, aircraft and other carriers, which is composed of a boom, rigging and a winch to form a retractable system, including a davit, crossbar rigging, gangway winch and auxiliary rigging components. The davit is usually installed on the middle plate or side plate of the ship body, and the crossbar is arranged on both sides of the gangway.

[0003] Traditional pilot gangways are usually simple in structure, mainly composed of two main load-bearing ropes and a series of parallel wooden or composite material steps. The specific structure and working mode have the following inherent defects: 1. Insufficient safety limit, with the risk of falling: lack of effective body limit: the traditional gangway is only a passive climbing channel, and there is no active connection or constraint between the body of the pilot and the gangway. Once the body is tired or the foot slips due to wind and wave, falling accidents are prone to occur, and the safety completely depends on the physical strength and balance ability of the pilot. 2. No auxiliary lifting mechanism: when the pilot is tired, injured or needs to be quickly transferred, the traditional gangway cannot provide any assistance. The whole process of going up and down completely relies on the pilot to climb by hand, which not only is low in efficiency, but also significantly increases the risk in emergency situations (such as sudden deterioration of sea conditions). 3. Poor stability and rigidity of the ladder body: prone to twisting and swinging. 4. Lack of rigid support: the steps are only guided by ropes, which cannot provide a stable and firm footstep plane, and the feet are prone to fatigue, especially when carrying equipment. 4. Difficulty in assembling, fixing and adjusting: the rope fixing method is backward: the fixing between the main load-bearing rope and the step mainly adopts traditional knots (such as clove hitch) or simple perforated structure. 5. Difficulty in length and spacing adjustment: the spacing between the steps of the traditional gangway is usually fixed, which cannot be adjusted according to the height of different pilots or work habits, affecting the comfort of use.

[0004] In summary, the traditional pilot gangway usually has less safety limit for the pilot, insufficient stability of the ladder body, and difficulty in actively moving the position in a tired state, which seriously affects the work efficiency and safety. In order to avoid the above situation, the present application provides a pilot gangway system integrated with active safety limit, controllable power assistance and dynamic rigid support, which can provide a safe, labor-saving, stable and quickly adaptable climbing channel for the pilot in bad sea conditions.

[0019] Compared with the prior art, the embodiments of this application have the following main advantages: 1. The support plate assembly provides a stable foot platform, and the sliding groove design of the lower support plate allows the uprights of the ladder assembly to slide, facilitating the folding, storage, and unfolding of the ladder. The buffer seat is hinged through the lower connecting shaft, which can absorb the impact force during climbing, reduce fatigue, and improve comfort. The overall structure enhances the rigidity of the ladder, prevents swaying, and reduces operational risks.

[0020] 2.

A buffer seat 304 is fixedly connected to the outer wall of the lower connecting shaft 303.

[0029] It should be noted that, since water pilots need to place the ladder first and then climb it during actual operations, traditional ladders usually offer few safety restrictions and are less safe. Furthermore, when physically fatigued, it is difficult for them to actively move, which affects work efficiency.

[0030] Specifically, in this embodiment, the solution mainly utilizes the arrangement and coordination of the suspension plate 1, tie rod base 6, support plate assembly 3, escalator assembly 2, fixed rope threading 7, handrail rope 8, winch assembly 5, safety rope 9, and rotating V-shaft assembly 4. In use: Ladder assembly stage: Rope securing: Pass the securing rope 7 through the first rope hole 2021 on the base 201 of the multiple escalator components 2 in sequence, and pass the handrail rope 8 through the second rope hole 205 at the top of the upright 203.

[0031] Spacing adjustment: Adjust the spacing between ladder components 2 according to the pilot's work habits or the ship's structure to ensure climbing comfort and safety.

[0032] Fastening and fixing: For the fixed rope 7, by tightening the fastening screws 206 on both sides of the base 201, the pressure rod 2022 is pushed to move, which in turn drives the insertion plate 2024 to overcome the resistance of the tension spring 2023, so that the sharp-angled insertion block at the bottom of the insertion plate 2024 is inserted into the fixed rope 7 to achieve rigid fixation.

[0033] For the handrail rope 8, by rotating the adjusting screw 2041, the upper spring cylinder 2042 and the upper limit roller 2043 are pushed downward, and together with the lower limit roller 2045 on the lower spring cylinder 2044, they squeeze the handrail rope 8 to achieve flexible clamping and fixation.

[0034] Overall connection: Connect the assembled escalator assembly 2 to the support plate assembly 3, wherein the upright 203 is embedded in the groove of the lower support plate 302 to form an overall hanging ladder structure.

[0035] Ladder installation phase: The ladder is fixed to a predetermined position on the side of the ship or at the top of the work surface by means of the suspension plate 1, such as the mid-plate or outer side plate of the hull.

[0036] Release the support plate assembly 3 and the ladder assembly 2, allowing them to hang naturally to the working height. The support rod 301 is hinged to the suspension plate 1 via the tie rod base 6, ensuring the stability of the ladder when it is deployed.

[0037] Safety preparation phase: The pilot attaches one end of the safety rope 9 to his safety harness and the other end to the turntable 5031 of the winch assembly 5. The safety rope 9 is pre-wound onto the turntable 5031 for use in lifting and lowering.

[0038] Climbing and Assisted Movement Phase: The water guide climbs along the support plate assembly 3 and the ladder assembly 2, holding onto the handrail rope 8 to maintain balance.

[0039] Remote-controlled electric mode: When the pilot needs to move with less effort, such as when fatigued or needing rapid ascent and descent, the auxiliary drive unit 502 can be controlled via remote control. When the telescopic hydraulic cylinder 5021 is activated, it pushes the motor base 5022 to move towards the turntable 5031, causing the drive gear 5024 at the end of the rotating shaft 5023 to insert into and mesh with the internal gear ring 5032.

[0040] The motor is started, which drives the drive gear 5024 to rotate through the transmission shaft, thereby rotating the internal gear ring 5032 and the turntable 5031, thus raising and lowering the safety rope 9 to assist the pilot in ascending or descending.

[0041] Manual backup mode: When electric mode fails or fine control is required: The remote-controlled telescopic hydraulic cylinder 5021 retracts, causing the drive gear 5024 to disengage from the internal gear ring 5032.

[0042] The operator manually rotates the manual handle 5033 to drive the turntable 5031 to rotate, and retracts or extends the safety rope 9 to control the position of the pilot.

[0043] Cushioning and support: During climbing, the cushioning seat 304 of the support plate assembly 3 is connected to the lower support plate 302 via the lower connecting shaft 303, providing foot support and reducing impact.

[0044] Stable phase of the hoisting ladder: Secure the bottom of the ladder using the rotating V-shaft assembly 4: Adjusting the length of the telescopic boom 402: By rotating the sleeve and the boom, the telescopic boom 402 can be extended or shortened to accommodate the distance between the ship and the dock or work surface.

[0045] Throwing rope 403: Throw the hook 404 toward a fixed point, such as a dock railing. Adjust the angle by rotating the V-shaft 401 to keep the bottom of the ladder close to the working surface and reduce swaying.

[0046] This stage can be performed before or during the climb to ensure the ladder remains stable in windy and wavy conditions.

[0047] The entire workflow enables rapid assembly, safe installation, assisted climbing, and dynamic stabilization of the ladder, significantly improving the efficiency and safety of water diversion workers' operations.

[0048] In this embodiment, the support plate assembly 3 provides a stable foot platform; the groove design of the lower support plate 302 allows the uprights 203 of the ladder assembly 2 to slide, facilitating the folding, storage, and unfolding of the ladder; the buffer seat 304 is hinged through the lower connecting shaft 303, which can absorb the impact force during climbing, reduce fatigue, and improve comfort; the overall structure enhances the rigidity of the ladder, prevents swaying, and reduces operational risks. Through the design of escalator component 2: the first limiting member 202 rigidly fixes the rope 7 through the insert plate 2024 and the acute-angle insert block, ensuring that the step spacing is adjustable and the connection is firm, adapting to different operation requirements; the second limiting member 204 flexibly clamps the handrail rope 8 through the upper limiting roller 2043 and the lower limiting roller 2045, providing an elastic grip point, reducing hand fatigue, and preventing rope slippage; the modular design of multiple sets of escalator components 2 facilitates maintenance and replacement, improving the durability and adaptability of the escalator.
