Description

Technical Field

[0001] This utility model relates to the field of marine gangplank technology, and more specifically, to an adjustable-length marine gangplank. Background Technology

[0002] A boat gangway is a platform used to connect a boat to the shore when it is docked, providing a safe and convenient passage for people. For example, a barge gangway structure proposed in patent application number 201920983425.7 includes a hull, a gangway body, a first connecting rod, a second connecting rod, and a hydraulic cylinder. The fixed end of the hydraulic cylinder is hinged to the hull. The stern of the hull is provided with a main hinge plate and a connecting rod hinge plate. The stern of the gangway body is provided with a gangway hinge plate. The two ends of the first connecting rod are respectively hinged to the connecting rod hinge plate and the movable end of the hydraulic cylinder. The two ends of the second connecting rod are respectively hinged to the gangway hinge plate and the movable end of the hydraulic cylinder. Columns are provided on both sides of the stern of the hull, and cables connect the columns to the gangway body. A locking structure is connected to the hull, and the locking structure can be press-fitted to the gangway body.

[0003] The above-mentioned plan has a fixed length of gangplank, which requires the driver to moor the ship close to the shore before the gangplank can be set up. The adjustment process is quite troublesome. Moreover, when the ship is moored in a long shallow area, the gangplank length limitation poses a significant safety hazard during the mooring process. Therefore, we have made an improvement and proposed an adjustable-length gangplank for ships. Utility Model Content

[0004] The main purpose of this utility model is to provide an adjustable-length ship gangplank, which can effectively solve the problem that the length of the ship gangplank is fixed, requiring the driver to moor the ship close to the shore before the gangplank can be set up, which is a troublesome adjustment process. Moreover, when the ship is moored in a long shallow water area near the shore, the gangplank length limitation poses a significant safety hazard during the mooring process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable-length boat ramp includes a hull, with a ramp rotatably mounted at one end of the hull. Side plates are installed on both sides of the upper surface of the hull. A hydraulic cylinder is installed on one side of the upper surface of each side plate. An oil tank for supplying oil to the hydraulic cylinder is installed on one side of the upper surface of each side plate. A support rod is also installed on one side of the upper surface of each side plate. A pulley is provided at the top of the support rod. A connecting rope is connected to the output end of the hydraulic cylinder. One end of the connecting rope passes through the pulley and is fixedly connected to one end of the ramp. An extension mechanism is provided at the bottom of the ramp.

[0007] Preferably, mounting seats are installed on both sides of one end surface of the hull, and a mounting rod is installed between the two mounting seats. A rotating sleeve is installed on one end surface of the gangplank, and the rotating sleeve is rotatably sleeved on the rod of the mounting rod.

[0008] Preferably, the lower surface of the scaffold is provided with a groove, and the inner walls on both sides of the groove are provided with first mounting grooves. A second mounting groove is also provided on one side of the lower surface of the scaffold, and a cover plate is installed at the bottom of the second mounting groove.

[0009] Preferably, the extension mechanism includes a synchronous motor and a synchronous controller. The synchronous motor is installed on both sides inside the second mounting slot, and the synchronous controller is installed inside the second mounting slot. The synchronous controller is used to control the two synchronous motors.

[0010] Preferably, each of the synchronous motors has an adjusting screw installed at its output end and inside the first mounting slot, with one end of each adjusting screw rotatably mounted on the inner wall of one end of the first mounting slot.

[0011] Preferably, each of the adjusting screws has a screw sleeve installed on its shaft by means of a threaded engagement, and the outer side of each screw sleeve is slidably disposed inside the first mounting groove at the corresponding position.

[0012] Preferably, an extension support plate is installed between the two lead screw sleeves, and the extension support plate is disposed inside the groove.

[0013] Preferably, a control cabinet is installed on one side of the upper surface of one of the side panels, and the control cabinet is electrically connected to the synchronous controller.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The synchronous controller controls two synchronous motors to rotate synchronously, which in turn controls the lead screw sleeves on both sides to move the extension support plate synchronously. This allows the extension support plate to extend to the outside of the gangplank, extending the overall length of the gangplank and enabling the boat to dock at a greater distance from the shore. This makes docking easier and provides sufficient distance for docking in shallow waters with longer sections of shore. It also makes the gangplank safer and has a wider range of applications.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 , Figure 2 As shown, an adjustable-length boat ramp includes a hull 1, a ramp 2 rotatably mounted at one end of the hull 1, side plates 8 mounted on both sides of the upper surface of the hull 1, a hydraulic cylinder 3 mounted on one side of the upper surface of each side plate 8, an oil tank 301 for supplying oil to the hydraulic cylinder 3 mounted on one side of the upper surface of each side plate 8, a support rod 4 mounted on one side of the upper surface of each side plate 8, a pulley 5 mounted on the top of the support rod 4, a connecting rope 6 connected to the output end of the hydraulic cylinder 3, one end of the connecting rope 6 passing through the pulley 5 and fixedly connected to one end of the ramp 2, and an extension mechanism 7 mounted at the bottom of the ramp 2.

[0023] like Figure 2 , Figure 3 As shown, mounting seats 101 are installed on both sides of one end surface of the hull 1, and mounting rod 102 is installed between the two mounting seats 101. A rotating sleeve 201 is installed on one end surface of the ramp 2, and the rotating sleeve 201 is rotatably sleeved on the rod of the mounting rod 102.

[0024] By rotating the sleeve 201 and the mounting rod 102, the plank 2 is rotated. When the hydraulic cylinder 3 pulls the connecting rope 6, the plank 2 can be rotated, thereby controlling the raising and lowering of the plank 2, making it more convenient to use.

[0025] like Figure 2 , Figure 3 , Figure 4 As shown, a groove 202 is formed on the lower surface of the ramp 2, and first mounting slots 2021 are formed on the inner walls of both sides of the groove 202. A second mounting slot 203 is also formed on one side of the lower surface of the ramp 2. A cover plate 204 is installed at the bottom of the second mounting slot 203. The extension mechanism 7 includes a synchronous motor 701 and a synchronous controller 702. The synchronous motor 701 is installed on both sides inside the second mounting slot 203, and the synchronous controller 702 is installed inside the second mounting slot 203. The synchronous controller 702 is used to control the two synchronous motors 701. The output end of each synchronous motor 701 is located at the first mounting slot. Each groove 2021 is equipped with an adjusting screw 703. One end of each adjusting screw 703 is rotatably mounted on the inner wall of one end of the first mounting groove 2021. Each adjusting screw 703 is fitted with a screw sleeve 704 by thread. The outer side of each screw sleeve 704 is slidably disposed inside the first mounting groove 2021 at the corresponding position. An extension support plate 705 is installed between two screw sleeves 704. The extension support plate 705 is disposed inside the groove 202. A control cabinet 9 is installed on one side of the upper surface of one of the side plates 8. The control cabinet 9 is electrically connected to the synchronous controller 702.

[0026] The operating status of the synchronous controller 702 can be controlled through the control cabinet 9. The synchronous controller 702 can control the two synchronous motors 701 to rotate synchronously, and then control the extension support plate 705 to extend from the inside of the groove 202, extending the overall length of the jump board 2, making the jump board 2 more versatile.

[0027] The working principle of this adjustable-length marine gangway:

[0028] The connecting rope 6 is moved by the hydraulic cylinder 3, which in turn pulls the gangplank 2 to rotate around the mounting rod 102. This allows for control of the gangplank 2's raising and lowering. During the placement of the gangplank 2, the synchronous controller 702 is controlled by the control cabinet 9. The synchronous controller 702 controls two synchronous motors 701 to rotate synchronously. Under the threaded engagement between the adjusting screw 703 and the screw sleeve 704, the screw sleeves 704 on both sides synchronously drive the extension support plate 705 to move. This allows the extension support plate 705 to extend to the outside of the gangplank 2, extending the overall length of the gangplank 2. This allows the boat 1 to have a greater mooring distance from the shore, making mooring operations simpler. When mooring in shallow waters with long shores, the gangplank 2 also has a sufficient distance, making it safer and more widely applicable.

[0029] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
