Description

Technical Field

[0001] This utility model relates to the field of transportation equipment and facilities technology, and in particular to a height-adjustable boat-shore connection ramp. Background Technology

[0002] Currently, waterway transportation is booming, with passenger transport becoming an important component, and an increasing number of passenger terminals of various sizes are being built. Especially on inland waterways, with the rapid integration of transportation and tourism, the demand for high-quality, suitable terminals is growing.

[0003] Currently, inland river terminals are not suitable for passenger ships and yachts to berth and disembark passengers, mainly in two aspects: First, the change in water level makes it inconvenient for ships to berth and disembark passengers. Seasonal water level differences can cause a large height difference between the ship and the dock front, bringing many inconveniences and potential risks to ship-to-shore connection operations. Second, the different sizes of ships make it inconvenient for ships to berth and disembark passengers. After large ships berth, the disembarkation point (the disembarkation point is at the sides of the ship) is much higher than the dock front, while the disembarkation point of small ships is much lower than the dock front. Currently, when various types of ships of different sizes berth, it is usually necessary to use different types and lengths of external gangplanks or manual pulling to allow passengers to board and disembark. This is not only inefficient and time-consuming, but also unsafe and poses significant safety hazards.

[0004] It should be noted that a large ship is one whose disembarkation point is higher than the highest point of the pier's edge (e.g., 1 or 2 meters higher); a small ship is one whose disembarkation point is lower than the highest point of the pier's edge (e.g., 1 or 2 meters lower).

[0005] Therefore, there is an urgent need to develop equipment that can solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the technical deficiencies of existing technologies by providing a height-adjustable boat-shore connection ramp.

[0007] Therefore, this utility model provides a height-adjustable ship-shore connection gangway, which includes a land-side gangway, a water-side gangway, a vertical lifting gangway, a support column, a wharf front edge, a winch, an electro-hydraulic rod, a pin fixing device, and a limit frame. The lower end of the support column is embedded in the front edge of the dock; The limit frame is fixedly installed at the outermost edge of the dock facing the ship. A vertical lifting plate is placed on the inside of the limit frame; A winch is installed at the top of the pier's edge; The winch is connected to the vertical lifting plate and is used to drive the vertical lifting plate to move up and down. The landside ramp, on the side furthest from the ship, is hinged to the front edge of the dock. The near-water end of the land-side gangway facing the ship is slidably connected to the top of the water-side gangway; The water-side ramp is hinged to the top of the vertical lifting platform at the water-near end facing the ship. The water-side gangway is slidably connected to the top of the support column on the side furthest from the ship. An electro-hydraulic rod, connected to a pin retainer, is used to drive the pin retainer to move horizontally left and right, thereby allowing the pin retainer to be inserted and fixed to the vertical lifting plate.

[0008] As can be seen from the technical solution provided by this utility model above, compared with the prior art, this utility model provides a height-adjustable boat-shore connection ramp. Its structural design is scientific. By adopting a sliding and lifting structural design, it solves the problem of inconsistent boat-shore connection heights when various types of ships berth. When various types of ships of different sizes berth, the ramp of this utility model can be adjusted to be consistent with the height of the ship's disembarkation point, improving the convenience and safety of passengers disembarking, and has significant practical significance.

[0009] By applying this utility model, the design height of the pier front edge at the passenger disembarkation position can be lower than the land area behind the pier (specifically, the height of the lower platform of the pier is lower than the upper platform of the pier), which can significantly reduce the pier construction cost. By applying this utility model, the main consumable components relied upon by the sliding design are the sliding wheel and the sliding rotor, which have a simple structure and low cost. By applying this utility model, the electric winch and the electric hydraulic rod can quickly align the gangway with the ship's disembarkation point, thus improving the efficiency of ship-shore connection. This utility model addresses the technical shortcomings of existing ship-shore connection ramps, such as their simplicity, limited applicability, and low safety and convenience. It proposes a sliding, liftable, and automatically controlled ship-shore connection ramp solution, which can significantly reduce wharf construction costs, improve ship-shore connection efficiency and safety, and has good applicability to passenger wharves with large water level fluctuations and a variety of berthing vessel types.

[0010] This invention achieves seamless connection between land-side and water-side gangways, as well as between water-side gangways and various types of vessels, by controlling the height of the gangways with a winch and by controlling the flexible connection between gangways through a sliding design. This invention is suitable for passenger terminals with large water level fluctuations and a variety of vessel types, and can significantly reduce terminal construction costs and improve the efficiency and safety of ship-shore connections.

[0019] In specific implementation, the water-side jump board 2 includes a water-side jump board hinge cylinder 21 and a jump board groove 22; Two water-side ramp hinge cylinders 21 are symmetrically fixed at the front and rear of the water-side ramp 2 near the water end; At the top front and rear ends of the water-side diving board 2, there is a diving board groove 22 that runs along the long side; The specific structural design of the sliding connection between the near-water end of the land-side gangway 1 facing the ship and the water-side gangway 2 is as follows: Two sliding wheels 11 on the near-water end of the land-side jumping board 1 are correspondingly set with two jumping board grooves on the top of the water-side jumping board 2, and these two sliding wheels 11 are located in the two jumping board grooves 22 and are in sliding engagement with the two jumping board grooves 22. It should be noted that the two springboard grooves 22 serve as the sliding tracks for the sliding wheels.

[0020] In specific implementation, the vertical lifting plate 3 includes a vertical lifting plate hinge cylinder 31 and a hinge cylindrical shaft 39; The water-side ramp 2, facing the ship, is hinged (i.e., rotatably connected) to the vertical lifting plate 3 at its near-water end. The specific structural design is as follows: The two water-side springboard hinge cylinders 21 on the water-side springboard 2 are hinged to the vertical lifting plate hinge cylinder 31 at the top of the vertical lifting plate 3 through longitudinally distributed hinged cylindrical shafts 39. Furthermore, three vertical lifting plate hinge cylinders 31 are arranged sequentially from front to back on the top of the vertical lifting plate 3; On the vertical lifting plate hinge cylinder 31 located at the rearmost side, there are longitudinally distributed hinged cylindrical shafts inserted into blind holes.

The internal thread at the front of bolt hole 32 is threadedly fixed to a bolt 36; The rear end face of bolt 36 abuts against the front end face of hinged cylindrical shaft 39 (i.e., they are in tight contact). Furthermore, a bolt post 37 is provided at the center of the outer side of the bolt 36; Bolt side posts 38 are provided on the outer edge of bolt 36; A bolt groove 370 is formed between the bolt central post 37 and the bolt side post 38 for applying external force; It should be noted that, for this utility model, the hinged cylindrical shaft 39 can be fixed by screwing the bolt 36 into the bolt hole 32. In addition, a strip-shaped hard object (such as a metal plate or a metal roller) can be inserted between the bolt central column 37 and the bolt side column 38 and then rotated to achieve the tightening and loosening of the bolt 36.

[0021] In this utility model, specifically, vertically distributed guardrails (e.g., 1.5 meters high) are provided on the top front and rear sides of the land-side ramp 1 and the water-side ramp 2, protruding upwards along the long side.

[0022] In this invention, specifically, the longitudinal length of the land-side ramp 1 and the water-side ramp 2 is typically greater than 2 meters. Of course, other longitudinal length values ​​are also possible, to facilitate visitor passage.

[0023] In this utility model, specifically, the support column 4 includes an anti-slip column 41, a springboard sliding groove 42, a sliding rotor groove 43, and a sliding rotor 44; Two anti-slip pillars 41 are symmetrically arranged on the front and rear sides of the top of the pillar 4; At the top front and rear ends of the support column 4, two sliding rotors 44 are pivotally connected (i.e., rotatably connected); The bottom surface of the water-side ramp 2 on the side away from the ship, near the land, contacts the top surface of the sliding rotor 44, and the two are connected by sliding engagement. Furthermore, the top of the support column 4 is provided with two sliding rotor slots 43, each of which is centrally connected (i.e. rotatably connected) to a sliding rotor 44.

[0024] It should be noted that the top of the support column 4 is provided with two sliding rotor grooves 43 into which the sliding rotor 44 is placed. Then the water-side jumping plate 2 is placed in the jumping plate sliding groove 42. Under the action of the sliding rotor 44 and the restriction of the anti-slip column 41, the water-side jumping plate 2 will slide on the support column 4. Furthermore, the lower end of the support column 4 is embedded in the lower platform 52 of the wharf front 5.

[0025] It should be noted that, in the present utility model, a sliding rotor (44) is installed at the upper end of a support post (4), and the water-side gangplank (2) can slide flexibly under the action of the sliding rotor (44); meanwhile, the design of an anti-slipping-out post (41) at the upper end of the support post (4) ensures that the water-side gangplank (2) is always located at the upper end of the support post (4).

[0026] In the present utility model, for specific implementation, a limiting frame (9) is fixedly and outwardly protrudingly disposed on a side, facing a ship, of a lower wharf platform (52) at a wharf front (5); A vertical lifting plate fixing groove (92) is formed between the limiting frame (9) and the lower wharf platform (52); A vertically distributed vertical lifting plate (3) is accommodated inside the vertical lifting plate fixing groove (92); It should be noted that the vertical lifting plate (3) is installed inside the vertical lifting plate fixing groove (92) of the limiting frame (9) and can only move up and down; A winch (6) is disposed at the top of the lower wharf platform (52) at the wharf front (5); The winch (6) comprises an electric winch (61) and a cable (62); A vertically distributed cable groove (34) is disposed at the longitudinal middle part of a side, facing the winch (6) (i.e., the landward side), of the vertical lifting plate (3); A cable fastening hole (35) is transversely provided through the lower end of the cable groove (34); A winding drum on the electric winch (61) is connected with the cable fastening hole (35) through the cable (62).

[0027] It should be noted that the cable (62) wound on the electric winch (61) is fastened to the lower end of the vertical lifting plate (3); when the electric winch (61) takes up the cable (62), the vertical lifting plate (3) ascends, and when the electric winch (61) pays out the cable (62), the vertical lifting plate (3) descends; It should be noted that, in the present utility model, the limiting frame (9) is fixed to the lower wharf platform (52) at the wharf front (5) by bolts passing through bolt holes (91), and the vertical lifting plate fixing groove (92) is formed between the limiting frame (9) and the lower wharf platform (52) at the wharf front (5) to ensure the vertical movement of the vertical lifting plate (3); Further, the shape of the limiting frame (9) is an inverted U-shape.

[0028] It should be noted that, in the present utility model, the winding drum on the electric winch (61) of the winch (6) is connected with the cable fastening hole (35) through the cable (62); when the electric winch (61) is started, the cable in the cable groove (34) is pulled up or paid out to drive the vertical lifting plate (3) to move vertically upward or downward; Further, when the cable (62) is in a dynamic moving process (i.e., in the process of being pulled up or paid out), the rotation direction of the winding drum on the electric winch (61) is tangent to the moving direction of the cable (62) (i.e., the rope running direction).

[0029] It should be noted that electric winches are existing conventional mechanical equipment. A winch is a small, lightweight lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects; it is also called a winch. Winches can lift heavy objects vertically, and pull them horizontally or at an angle. Electric winches are a common structure and will not be described in detail here. For example, a heavy-duty winch (1-ton specification) from the Chenghua Juling brand can be used.

[0030] Furthermore, a fixed pulley is also installed at the top right end of the lower platform 52 of the pier front 5; The fixed pulley is closer to the vertical lifting plate 3 than the drum on the electric winch 61, specifically on the right side of the drum on the electric winch 61. The cable 62 wound on the electric winch 61 passes around the fixed pulley and is connected to the vertical lifting plate 3 (specifically, it is connected to the cable fixing hole 35).

[0031] In practice, multiple limiting pieces 340 are fixedly installed from top to bottom on the side of the cable groove 34 facing the winch 6 (for example, three limiting pieces 340 are distributed at the upper, middle and lower positions of the cable groove 34, figure omitted). The limiting piece 340 is used to restrain the cable 62 within the cable groove 34; The limiting piece 340 is located to the left of the cable 62 inside the cable groove 34.

[0032] In this utility model, specifically, the vertical lifting plate 3 is provided with multiple pairs of transversely distributed pin holes 33 on the side facing the winch 6 (i.e., the near-land side). Multiple pairs of pin holes 33 are evenly spaced from top to bottom (vertical spacing can be 5 cm); Each pair of pin holes 33 is symmetrically arranged on the front and rear sides of the cable groove 34. The electro-hydraulic rod 7 includes a telescopic rod 71 and a first hinge joint 72; The pin retainer 8 includes a pin 81 and a second hinge joint 82; The electro-hydraulic rod 7 is equipped with a telescopic rod 71 at the water-near end facing the ship, and a first hinge joint 72 is provided at the end of the telescopic rod 71 facing the ship. The pin retainer 8 has two pins 81 on the water-near end facing the side of the ship; Two pins 81 are set to correspond to a pair of pin holes 33 on the vertical lifting plate 3; Two pins 81 are used to move horizontally under the drive of the electric hydraulic rod 7, so as to be horizontally inserted into a pair of pin holes 33 on the vertical lifting plate 3, thereby fixing the position of the vertical lifting plate 3. The pin retainer 8 has two second hinge joints 82 on the side away from the ship. Both the first hinge joint 72 and the second hinge joint 82 have longitudinally distributed central through holes; The first hinge joint 72 of the electro-hydraulic rod 7 is located in the longitudinal gap between the two second hinge joints 82; The first hinge joint 72 of the electric hydraulic rod 7 is hinged to the two second hinge joints 82 on the pin retainer 8 by longitudinally distributed second hinge shafts. It should be noted that the electric hydraulic rod 7 drives and controls the pin retainer 8 to move horizontally; when the vertical lifting plate 3 needs to be fixed at a certain height under the action of the electric winch 61, the electric hydraulic rod 7 drives and controls the pin 81 on the pin retainer 8 to move horizontally, so that the pin 81 is inserted into the insertion hole 33 of the vertical lifting plate 3, thereby fixing the vertical lifting plate 3.

[0033] It should be noted that after the second hinge shaft passes longitudinally through two second hinge joints 82 and one first hinge joint 72, its two ends are respectively threaded and fixedly connected to a second fastening nut. The diameter of the central through hole of the first hinge joint 72 is larger than the diameter of the second hinge shaft.

[0034] It should be noted that the first hinge joint 72 of the electric hydraulic rod 7 is connected to the second hinge joint 82 of the pin retainer 8. When the vertical lifting plate 3 is adjusted to a certain height (i.e., the height of the top of the vertical lifting plate 3 is required to be consistent with the height of the ship's disembarkation point), and it is necessary to fix it at this height, the telescopic rod 71 of the electric hydraulic rod 7 controls the horizontal movement of the pin 81 of the pin retainer 8 and inserts it into the pin hole 33 of the vertical lifting plate 3 to achieve fixation.

[0035] It should be noted that the vertical lifting plate 3 is set inside the limiting frame 9 and is constrained by the limiting frame 9, so it will not tilt. It moves vertically under the action of the winch 6 and can be vertically fixed under the action of the pin retainer 8 controlled by the electric hydraulic rod 7.

[0036] In practice, the lower platform 52 of the wharf front 5 has a reserved mounting hole for fixing the electric hydraulic rod 7, and an opening slot for allowing the pin retainer 8 to move horizontally. The opening slot is open on both the left and right sides, so that the pin 81 of the pin retainer 8 can extend to the right (i.e., the direction of the ship) and be inserted into the pin hole 33 of the vertical lifting plate 3.

[0037] In this invention, specifically, the vertical thickness of the pin 81 is less than the vertical height of the pin hole 33, thereby providing fault tolerance.

[0038] It should be noted that if there is a certain misalignment between the pin 81 and the pin hole 33, the position of the pin hole 33 can be adjusted by slightly raising or lowering the cable 61, so as to achieve the docking between the pin 81 of the pin retainer 8 and the pin hole 3 of the vertical lifting plate 3.

[0039] In this utility model, specifically, the front and rear ends of the limiting frame 9 include multiple bolt holes 91; The limiting frame 9 is fixedly connected to the lower platform 52 of the wharf front edge 5 by multiple fixing bolts.

[0040] After the fixing bolt passes through the bolt hole 91, it is fixedly connected to the lower platform 52 of the wharf front edge 5.

[0041] It should be noted that the fixing bolts can be expansion bolts (screws), which are used to fix the limit frame to the right side of the lower platform 52 of the dock.

[0042] In this utility model, specifically, the materials of the upper platform 51 and the lower platform 52 of the wharf are both reinforced concrete.

[0043] To better understand the technical solution of this utility model, the working principle of this utility model is explained below.

[0044] The height-adjustable boat-to-shore gangway provided by this utility model includes the following operating modes: I. Working mode for berthing large ships; The berthing operation mode for large ships includes the following procedures: In step S11, the electric winch 61 pulls the vertical lifting plate 3 upward through the cable 61, so that the vertical lifting plate 3 and the near-water end of the water-side jump plate 2 hinged at the top gradually rise together. In step S12, when the height of the near-water end of the water-side gangplank 2 rises to the same height as the disembarkation point of the large ship, the cable 61 remains stationary. At this time, the electric hydraulic rod 7 drives the pin fixing device 8 to move horizontally to the right, so that the pin 81 on the near-water end of the pin fixing device 8 is horizontally inserted into the pin hole 33 of the vertical lifting plate 3, thereby fixing the vertical lifting plate 3 and stopping the electric winch 61. At this time, the tourists get off the disembarkation point of the large ship, step onto the water-side gangplank 2, walk along the water-side gangplank 2 to the land-side gangplank 1, and then walk forward along the land-side gangplank 1 to the dock platform 51 at the front edge of the dock 5, thus completing the disembarkation.

[0045] During the execution of steps S11 and S12 above, the landside ramp 1 will also tilt upward synchronously as the slope of the waterside ramp 2 increases.

[0046] In this utility model, specifically, "large ship" and "small ship" are relative concepts. The first manifestation can be as follows: Large ships refer to ships whose disembarkation point height is greater than the top height of the vertical lifting platform 3 on the front edge of the dock at this time; Small boats refer to vessels whose disembarkation point is lower than the height of the top of the vertical lifting platform 3 on the front edge of the dock at this time; It should be noted that if the top height of the vertical lifting platform 3 is equal to the top surface height of the dock platform 51 at the dock front 5, and equal to the disembarkation point height of the vessel that needs to disembark, then there is no need to adjust (no need to pull up or lower) the vertical lifting platform 3.

[0047] The second form of expression can be as follows: A large ship is a vessel whose disembarkation point is higher than the top surface of the platform 51 on the quay front edge 5 when it is necessary to disembark (for example, 1 meter or 2 meters higher). Small boats are vessels whose disembarkation point is lower than the height of the top surface of the platform 51 on the pier at the pier's edge (e.g., 1 or 2 meters lower). For the second scenario, in the non-working state (i.e., the initial state before the ship docks), the top height of the vertical lifting platform 3 is preferably equal to the top surface height of the platform 51 on the dock's front edge 5. In this case, when a large ship docks and passengers on board need to disembark, the vertical lifting platform 3 is raised; conversely, when a small boat docks and passengers on board need to disembark, the vertical lifting platform 3 is lowered.

[0048] In addition, it should be noted that in the non-working state (i.e. the initial state when the ship has not docked), the top height of the vertical lifting platform 3 is equal to the top surface height of the dock platform 51 at the dock front 5. If it is also equal to the disembarkation point height of the ship that needs to go ashore, then there is no need to adjust (no need to pull up or lower) the vertical lifting platform 3.

[0049] II. Small boat berthing operation mode; The berthing operation mode for small boats includes the following operations: In step S21, the electric winch 61 lowers the vertical lifting plate 3 downwards via the cable 61, thereby gradually reducing the height of the vertical lifting plate 3 and the near-water end of the water-side jump plate 2 hinged at its top. In step S22, when the height of the near-water end of the water-side gangplank 2 is lowered to the same height as the boat disembarkation point, the cable 61 remains stationary. At this time, the electric hydraulic rod 7 drives the pin fixing device 8 to move horizontally to the right, so that the pin 81 on the near-water end of the pin fixing device 8 is horizontally inserted into the pin hole 33 of the vertical lifting plate 3, thereby fixing the vertical lifting plate 3 and stopping the electric winch 61. At this time, the tourist gets off the boat, steps onto the water-side gangplank 2, walks along the water-side gangplank 2 to the land-side gangplank 1, and then walks forward along the land-side gangplank 1 to the dock platform 51 at the front edge of the dock 5, thus completing the tourist's disembarkation.

[0050] During the execution of steps S21 and S22 above, the landside ramp 1 will also tilt downwards synchronously as the slope of the waterside ramp 2 decreases.

[0051] Compared with existing technologies, the height-adjustable boat-shore connection gangway provided by this utility model is a sliding, liftable, and controllable boat-shore connection gangway, which has the following advantages: 1. The overall design of this utility model provides that the height of the front edge of the pier at the passenger disembarkation position can be lower than the land area behind it (specifically, the height of the lower platform 52 of the pier is lower than the upper platform 51 of the pier), which can significantly reduce the overall construction cost of the pier. 2. The sliding and lifting structural design provided by this utility model solves the problem of inconsistent ship-shore connection height when various types of ships are berthed. When different types of ships of different sizes are berthed, the gangplank can be adjusted to be consistent with the height of the ship's disembarkation point, improving the convenience and safety of disembarkation. 3. The sliding fit design provided by this utility model (specifically, the sliding fit design between the near-water end of the land-side gangway 1 facing the ship and the top of the water-side gangway 2, and the sliding fit design between the near-land end of the water-side gangway 2 away from the ship and the top of the support column 4) mainly relies on the consumable components of sliding wheels and sliding rotors, which have simple consumable structures and low costs. 4. This utility model can quickly align the gangway with the ship's disembarkation point by using an electric winch and an electric hydraulic rod, thus improving the efficiency of ship-shore connection. 5. Currently, there are no sliding, liftable, and controllable boat-shore connection ramps available domestically or internationally. This utility model fills the gap in the field of sliding, liftable, and controllable boat-shore connections.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
