Description

Technical Field

[0001] This utility model relates to the field of shipboard elevator technology, and in particular to a levelable, multi-functional modular shipboard elevator. Background Technology

[0002] As a vital passageway connecting docks and ships, boarding elevators are widely used in passenger terminals, cargo ports, shipyards, and other locations to facilitate the safe and efficient transfer of personnel and goods. With the continuous development of the shipping industry, ship tonnage and freeboard height are increasing daily, making traditional fixed boarding ladders or simple staircases insufficient to meet the diverse boarding needs with significant elevation differences, especially in situations with large tidal ranges, complex berth conditions, or where ships require maintenance or inspection.

[0003] Currently, common boarding equipment mainly includes fixed steel ladders, lifting platforms, and simple gangways. Fixed boarding ladders are difficult to adjust in height and angle after installation, and cannot adapt to changes in ship draft or differences in freeboard between different ship types. Simple gangways are usually lightweight, but have limited load-bearing capacity and lack protective and leveling functions. They also have poor stability under wind, waves, or ship rolling conditions, posing safety hazards. Furthermore, existing boarding equipment is mostly a single welded or fixed structure, making transportation and installation inconvenient, hindering rapid disassembly and reuse, and preventing flexible height combinations and attitude leveling according to dock site conditions.

[0004] In particular, when carrying out ship repairs or boarding operations at shore shipyards or certain temporary docks, the installation site is often uneven or even sloping. Traditional boarding equipment relies on pre-set flat foundations or complex civil engineering for fixation, and cannot be quickly leveled on-site to adapt to the terrain. This results in unstable equipment installation, the risk of tilting, and seriously affects personnel safety and the service life of the equipment.

[0005] Regarding passenger access, most boarding passages only have stairs, which is very inconvenient for the elderly, those with mobility issues, or those carrying heavy items. Elevators, on the other hand, are often complex in structure, occupy a large area, are costly, and are difficult to coordinate with staircases, easily leading to congestion and low efficiency. Furthermore, existing boarding equipment still has shortcomings in fall safety, crowd control, and ground adaptability, limiting its application in high-standard passenger terminals or ship repair operations.

[0006] Therefore, there is an urgent need for a boarding elevator that is height-adjustable, adapts to ground leveling, is quick to assemble, combines elevator and staircase functions, is safe and reliable, and can separate passenger flow, in order to meet the diverse boarding needs of modern ports, shipyards, and various complex site conditions.

[0038] The present invention will be further described below with reference to the accompanying drawings:

[0039] like Figures 1-6 As shown, a levelable, multi-functional, modular boarding elevator includes a ladder frame 1, a walkway 5, and an elevator 2 and steps 3 installed inside the ladder frame 1. The ladder frame 1 includes a bottom standard section 111, a top standard section 121, an elevator protective frame 141, and six middle standard sections 121. The bottom standard section 111 has nine telescopic support legs 4 on the ground. One end of the walkway 5 is connected to the top standard section 121, and the other end extends to the hull. The walkway 5 is used for people to walk onto the ship. The elevator 2 is located in the middle of the ladder frame 1, and the steps 3 are located inside the elevator frame 1. On one side of the elevator 2, the door of the elevator 2 is located away from the stair 3, which separates the flow of people on both sides, making it more orderly and convenient for management. The stair 3 includes 8 stair units, which are respectively set on the bottom standard section 111, the middle standard section 121 and the top standard section 121. The bottom standard section 111, the middle standard section 121, the top standard section 131 and the elevator protective frame 141 are all equipped with lifting lugs. When in use, the lifting lugs are connected to the cable, and the lower end of the cable is fixed to the ground at an angle, which can strengthen the fixation of the ladder frame 1.

[0040] Furthermore, the telescopic support leg 4 includes a support plate and a threaded column in the middle of the upper surface of the support plate. The lower surface of the bottom standard section 111 is provided with a threaded sleeve corresponding to the threaded column. The threaded column is inserted into the threaded sleeve through a threaded connection. When the ground of the installation site is uneven, the support plate can be rotated, and the threaded column will rotate and extend and retract within the threaded sleeve, so that the boarding elevator 2 can be firmly installed on uneven ground.

[0041] Furthermore, six middle standard sections 121 are stacked vertically, with adjacent middle standard sections 121 connected by flanges; the lower end of the bottom middle standard section 121 is connected to the upper end of the bottom standard section 111 by a flange, and the upper end of the top middle standard section 121 is connected to the top standard section 121 by a flange. An elevator safety frame 141 is installed at the upper end of the top standard section 121 corresponding to the elevator position 2, and the lower end of the elevator safety frame 141 is connected to the upper end of the top standard section 121 by a flange; Figure 3 As shown, an entrance door 112 is provided on the front side of the bottom standard section 111, and a boarding door 114 is set inside the bottom standard section 111 corresponding to the door of elevator 2. A first corridor 113 is set inside the bottom standard section 111 corresponding to the entrance door 112 and its two sides. One end of the first corridor 113 extends to the staircase 3, and the other end extends to the boarding door 114, so as to separate the boarding personnel. The entrance door 112 and the boarding door 114 are staggered and connected by the first corridor 113. People can queue for elevator 2 in the first corridor 113. If the entrance door 112 and the boarding door 114 are in the same place, it will cause congestion at the entrance door 112. Figure 5As shown, a boarding gate 134 is provided on the front side of the top standard section 121, and a descending door 133 is set inside the top standard section 121 corresponding to the door of the elevator 2. A second corridor 132 is set inside the top standard section 121 corresponding to the boarding gate 134 and its two sides. One end of the second corridor 132 extends to the stairs 3 and the other end extends to the descending door 133. This allows for the separation of boarding personnel, and the descending door 133 and the boarding gate 134 are staggered. The first corridor 113 connects and buffers the flow of people, preventing crowding at the boarding gate 134 and reducing safety risks. A trestle 5 is installed at the lower part of the boarding gate 134 of the top standard section 121, and the end of the trestle 5 away from the ladder frame 1 extends to the hull. A platform for placing counterweights is set around the lower part of the bottom standard section 111. The counterweights increase the anti-tipping ability of the ladder frame 1. The counterweights are water tanks, which are convenient to fill near the water and can be disassembled to drain.

[0042] Furthermore, elevator 2 includes a mounting plate 21, an elevator frame, and a car 231, with the mounting plate 21 fixedly mounted on the elevator frame 1; as Figure 7 As shown, the elevator frame is assembled from 17 splicing units. Each splicing unit includes a mounting frame 221, which is fixedly mounted on a mounting plate 21. Vertical guide tubes 222 are provided on both the left and right sides of the mounting frame 221. Guide wheels, U-shaped wheels, are installed on both sides of the elevator frame corresponding to the car 231, rolling up and down while locked onto the guide tubes 222. A traction system for moving the car 231 along the elevator frame is installed inside the elevator safety frame 141. The car 231 is also equipped with an anti-fall mechanism, such as... Figure 8 As shown, the fall protection mechanism includes a crawling gear, a fall protection gear 232, a ratchet 233, and a pawl 234. A fall protection rack 223 is fixedly installed on the front side of the elevator frame. A fall protection gear 232 corresponding to the fall protection rack is installed on the car 231. A ratchet 233 coaxial with the fall protection gear 232 is fixedly installed on the side of the fall protection gear 232. A bidirectional pawl 234 is provided on the car 231 below the ratchet 233. The pivot of the bidirectional pawl 234 is located at... At the upper right corner of its center of gravity, the weight difference between the two sides of the bidirectional pawl 234 about the rotating shaft is controlled at 50-100g. In this way, the bidirectional pawl 234 in its natural state will have the right pawl 234 sticking upward to the ratchet 233, and there will be a gap between the left pawl 234 and the outer circle of the ratchet 233. However, when the right pawl 234 is hit by the ratchet 233 quickly, the swing amplitude of the bidirectional pawl 234 will increase, and the left pawl 234 will be locked in the ratchet groove of the ratchet 233.

[0043] Working principle: During installation:

[0044] Transport the equipment to the designated location at the dock or shipyard;

[0045] Based on the ship's freeboard height, determine the required number of midship standard sections 121 and assemble them sequentially: first, place the bottom standard section 111 in position, then connect one or more midship standard sections 121 upwards via flanges, and finally install the top standard section 121 and the elevator guard frame 141 to form the complete ladder frame 1 body; observe the ground conditions of the installation site, and rotate the support plate of each telescopic support leg 4 under the bottom standard section 111. The support plate drives the threaded column to screw in or out of the threaded sleeve of the bottom standard section 111, thereby independently adjusting the support height of each support leg until all support plates are firmly in contact with the ground and the entire ladder frame 1 is in a vertical state, completing the leveling; place a water tank on the holding platform of the bottom standard section 111 and fill it with water, or connect a cable through the lifting lug, with the lower end of the cable diagonally fixed to the ground to enhance the stability of the ladder frame 1.

[0046] Inside the elevator frame 1, the mounting plate 21 is fixed in a predetermined position; the various splicing units of the elevator frame (mounting frame 221 with guide tube 222) are sequentially assembled on the mounting plate 21 to form a complete elevator frame structure; the traction system (such as motor, traction sheave, wire rope, etc.) is installed inside the elevator protective frame 141, and the wire rope is connected to the car 231; the car 231 is inserted into the guide tubes 222 on both sides of the elevator frame through the U-shaped guide wheels on both sides, so that the guide wheels can roll smoothly on the guide tubes 222; ensure that the anti-fall gear 232 on the car 231 meshes well with the anti-fall rack 223 fixed on the front side of the elevator frame, and check whether the coaxial ratchet 233 and the bidirectional pawl 234 on the car 231 operate normally and reliably.

[0047] One end of the pier 5 is hinged or securely connected to the lower part of the boarding opening 134 of the top standard section 121; the pitch angle or length of the pier 5 is adjusted according to the height and position of the ship's deck, and the end away from the ladder 1 is safely attached to the hull to form a stable boarding passage.

[0048] When personnel board the ship:

[0049] Ground level: Passengers enter through entrance door 112 on the front side of standard section 111 at the bottom. Options include:

[0050] Take elevator 2, walk through the first corridor 113 to the boarding door 114, and enter the car 231; the car 231 rises smoothly along the elevator frame under the drive of the traction system; use the step ladder 3, directly pass through the step ladder unit installed on the bottom standard section 111 to start going up, and can continuously pass through the step ladder units on each middle standard section 121 and the top standard section 121.

[0051] Top floor: After the elevator car 231 reaches the top, the passengers exit through the lower door 133 and proceed through the second corridor 132 to the boarding gate 134; the passengers using the stairs 3 go directly to the top standard section 121; all passengers pass through the boarding gate 134 and safely board the ship via the pier 5.

[0052] During normal elevator operation, the anti-fall gear 232 moves with the car 231 and rolls on the anti-fall rack 223, while the ratchet 233 moves accordingly, and the bidirectional pawl 234 does not interfere. If the elevator 2 falls out of control and the car 231 descends at an abnormally rapid speed, the rotational speed of the anti-fall gear 232 increases dramatically, causing the ratchet 233 to rotate at high speed. At this time, the right end of the bidirectional pawl 234 is violently struck by the ratchet teeth of the ratchet 233, causing the pawl 234 to rotate and engage in the ratchet groove of the ratchet 233, preventing the ratchet 233 from rotating and thus preventing the anti-fall gear 232 from rotating. Because the anti-fall gear 232 meshes with the fixed anti-fall rack 223, the car 231 is instantly locked onto the elevator frame, achieving fall protection.

[0053] Through the above implementation method, the boarding elevator 2 can be quickly and stably installed and leveled in complex sites, providing a safe, efficient and flexible dual-channel (elevator 2 / staircase 3) boarding solution, which is particularly suitable for various scenarios such as passenger terminals, ports and shipyards.

[0054] The foregoing has shown and described the basic principles, main features and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of this utility model as claimed.
