Description

Technical Field

[0001] The invention relates to the field of water conservancy and hydropower lifting mechanical equipment, and in particular to an adjustable shore-based ferry bridge. Background Art

[0002] A ship lift is a set of hydraulic lifting machinery that uses mechanical devices to lift ships and overcome vertical drops, allowing ships to be navigated, repaired, maintained, launched, etc.

[0003] The ship lifts used in shipyards are mainly dry-type ship lifts. Figure 1 As shown in the figure, the ship lift equipment lifts the ship on the lifting platform out of the water through the lifting system, and then transfers the ship to the ground maintenance position for inspection, maintenance and care through the hydraulic walking transfer trolley and the track parallel to the ground. Compared with the traditional pit dock, the ship lift can send the ship to different maintenance positions through the vertical cross track on the shore, so that the manufacturing and maintenance of the ship are not limited to the pit dock, which can improve the work efficiency of the shipyard. At the same time, the construction and maintenance environment of the shore dock has also been greatly improved compared with the pit dock.

[0004] Since the lifting platform is a steel structure, the weight of the ship lifted and transferred on the lifting platform is particularly large. When the walking transfer trolley transfers the ship from the lifting platform to the shore or transfers it in the opposite direction, the wheels of the walking transfer trolley enter and exit the lifting platform, causing a certain instantaneous deformation of the lifting platform when lifting and transferring the ship load. When the walking transfer trolley transfers the ship to the shore, since the shore is usually cast in concrete, its strength is higher than that of the lifting platform, and there is a huge difference in the stiffness of the shore and the lifting platform, the shore will basically not deform when bearing the pressure of the ship load. According to the weight of the ship and the size of the lifting platform, the instantaneous deformation of the lifting platform is 10-20cm, which is enough to affect the smooth operation of the walking transfer trolley, causing the trolley and the ship to vibrate greatly at the least, and causing the transfer trolley to get stuck or the ship to tilt and roll over at the worst.

[0005] To this end, the rigidity of the lifting platform is increased to ensure the smooth movement of the transfer vehicle in and out, but this method will increase the weight of the lifting platform and also increase the construction cost. Summary of the invention

[0006] 1. Technical problem to be solved by the invention

[0007] In order to solve the technical problem of instantaneous deformation of the lifting platform caused by the huge difference in stiffness between the shore and the lifting platform when the walking transfer vehicle enters and exits the lifting platform from the shore, the present invention provides an adjustable shore-based ferry bridge, which can convert the instantaneous deformation of the lifting platform into a gradual process, reduce the stiffness requirement for the lifting platform, and realize the smooth transition of the ship between the lifting platform and the shore.

[0008] 2. Technical solution

[0016] Optionally, two ends of the main beam are respectively embedded in a first groove provided on the surface of the shore foundation and a second groove provided on the surface of the lifting platform.

[0017] Optionally, a first limiting rubber is provided on the lower surface of the main beam at both ends of the main support seat, and a second limiting rubber is provided on the first groove surface and the second groove surface at corresponding positions on the main beam.

[0018] Optionally, a hydraulic cylinder is provided on the swing balancing slider to drive the swing balancing slider to slide on the sliding track.

[0020] 3. Beneficial effects

[0021] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0022] (1) The ferry bridge provided in the embodiment of the present invention is arranged between the shore and the lifting platform. Ships are usually transported by a walking transfer trolley. Since the lifting platform is a steel structure, the weight of the ship lifted and transferred on the lifting platform is particularly large. When the walking transfer trolley transfers the ship from the lifting platform to the shore or transfers it in the opposite direction, the wheels of the walking transfer trolley enter and exit the lifting platform, resulting in a certain instantaneous deformation of the lifting platform when lifting and transferring the ship load. When the walking transfer trolley transfers the ship to the shore, since the shore is usually cast in concrete, its strength is higher than that of the lifting platform, and there is a huge difference in the stiffness of the shore and the lifting platform, the shore will basically not deform when bearing the ship load. Therefore, in order to convert the instantaneous deformation of the lifting platform caused by the difference in stiffness between the shore and the lifting platform into a gradual process, a ferry bridge is arranged between the shore and the lifting platform, so that when the ship enters and exits the lifting platform from the shore, the weight of the transported ship is first transferred to the walking transfer trolley, then to the ferry bridge, and finally to the lifting platform or the shore through the transition of the ferry bridge. At the same time, the setting of the ferry bridge can enable the walking transfer trolley to smoothly enter and exit the lifting platform. The walking transfer trolley can then transfer the ship to the ground maintenance position on the shore for inspection, maintenance and upkeep.

[0023] (2) The ferry provided by the embodiment of the present invention is internally designed with a swing balancing slider and its sliding track. The sliding direction of the swing balancing slider is perpendicular to the direction of the main longitudinal beam and is driven by a hydraulic cylinder. By controlling the sliding position of the swing balancing slider, the ferry can swing freely between the shore and the lifting platform when it is unloaded. Through the swinging of the ferry, the force of the ship distributed on the walking transfer trolley is transferred to the lifting platform through the ferry, which is a gradually increasing process. The deformation of the lifting platform is also a gradually increasing process, thereby ensuring the smooth operation of the walking transfer trolley.

[0024] (3) The ferry provided in the embodiment of the present invention is designed with a main crossbeam, and a third track is arranged on the upper surface of the main crossbeam, which can connect the first track on the shore surface and the second track on the lifting platform without steps, so that the walking transfer vehicle can slide smoothly on the surface of the outdoor lifting platform on the shore surface.

[0025] (4) The first limit rubber is designed on the lower surface of the main beam at both ends of the ferry provided by the embodiment of the present invention, and the second limit rubber matching with the first limit rubber is arranged on the first groove surface on the shore and the second groove surface on the lifting platform and the corresponding position of the main beam. When the walking transfer trolley travels from the shore to the lifting platform, the swing balance slider is pushed to the shore side, and the ferry swings to the shore side. The first limit rubber on the lower surface of the end of the main beam overlaps with the second limit rubber at the corresponding position on the first groove of the shore, and the third track on the main beam of the ferry is stably docked with the first track on the shore. This ensures that the walking transfer trolley travels smoothly from the shore to the ferry. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Example 1

[0039] like Figure 1 As shown, after the conventional ship lift equipment lifts the ship 5 located on the lifting platform 2 out of the water through the lifting device 6, the ship 5 is transferred to the maintenance position on the ground by the walking transfer vehicle 4 for inspection, maintenance and care.

[0040] like Figure 2 , Figure 4 As shown, this embodiment provides an adjustable shore-based ferry bridge, including a ferry bridge 3, wherein the ferry bridge 3 is arranged between the shore 1 and the lifting platform 2, one end of the top of the ferry bridge 3 is connected to the shore 1, and the other end of the top of the ferry bridge 3 is connected to the lifting platform 2 which is lifted to the same horizontal position as the ferry bridge 3.

[0041] In this embodiment, when the ship 5 enters the predetermined position near the water shore, the ship 5 located above the lifting platform 2 is lifted from the water below the channel by the lifting device 6, and slowly lifted to be parallel to the shore 1. The ship 5 is usually transported by the walking transfer trolley 4. The walking transfer trolley 4 needs to perform track change operation according to actual needs during the movement. The process of the walking transfer trolley 4 transporting the lifting platform 2 to connect the ship 5 for track change movement is as follows: an electric or hydraulic jacking device is set at the bottom of the walking transfer trolley 4. When the jacking device lifts the ship 5 and the lifting platform 2 together, the walking transfer trolley 4 is out of the track and in a suspended state. The walking transfer trolley 4 rotates with the jacking device as the axis, and the rotation power is driven by a stepper motor or a hydraulic motor. When the walking transfer trolley 4 rotates to the direction of another running track, the jacking device is retracted, and the walking transfer trolley 4 re-contacts with the other track, thereby completing the track change of the walking transfer trolley 4.

[0042] The ship 5 is usually transported by the walking transfer trolley 4. Since the lifting platform 2 is a steel structure, the weight of the ship 5 lifted and transferred on the lifting platform 2 is particularly large. When the walking transfer trolley 4 transfers the ship 5 from the lifting platform 2 to the shore 1 or transfers it in the opposite direction, the wheels of the walking transfer trolley 4 enter and exit the lifting platform 2, causing a certain instantaneous deformation when the lifting platform 2 transfers the load of the ship 5. When the walking transfer trolley 4 transports the ship 5 to the shore 1, since the shore 1 is usually cast in concrete, its rigidity is higher than that of the lifting platform 2. There is a huge difference in rigidity between the shore 1 and the lifting platform 2, and the shore 1 will basically not deform when bearing the pressure of the ship load. Therefore, in order to transform the instantaneous deformation of the lifting platform 2 caused by the difference in stiffness between the shore base 1 and the lifting platform 2 into a gradual process, a ferry bridge 3 is set between the shore base 1 and the lifting platform 2, so that when the ship 5 enters and exits the lifting platform 2 from the shore base 1, the weight of the consigned ship 5 is first transferred to the walking transfer trolley 4 through the transition of the ferry bridge 3, then to the ferry bridge 3, and finally to the lifting platform 2 or the shore base 1. At the same time, the setting of the ferry bridge 3 enables the walking transfer trolley 4 to smoothly enter and exit the lifting platform 2. The ship 5 is then transferred to the ground maintenance position of the shore base 1 by the walking transfer trolley 4 for inspection, maintenance and upkeep.

[0043] like Figure 4 , Figure 6 As shown, an optional implementation is that a pit 11 is provided on the shore foundation 1, and the ferry bridge 3 is provided in the pit 11 of the shore foundation 1. A pit 11 having a size larger than the ferry bridge 3 is designed at the shore foundation 1 for placing the ferry bridge 3.

[0044] like Figure 5-7As shown, the ferry bridge 3 includes a main support seat 31, a main longitudinal beam 32 and one or more main cross beams 33. The main support seat 31 is arranged in the pit 11, the main longitudinal beam 32 is arranged in the main support seat 31, and the main cross beam 33 is arranged on the main support seat 31 and is perpendicular to the main longitudinal beam 32. The main support seat 31 of the ferry bridge 3 is welded by a steel structure, and the main longitudinal beam 32 is designed at the longitudinal symmetric center, and the main cross beam 33 is arranged in a direction perpendicular to the main longitudinal beam 32. The main cross beam 33 is arranged perpendicularly to the main longitudinal beam 32, which increases the strength of the main support seat 31 of the ferry bridge 3.

[0045] like Figure 5 , Figure 7 As shown, the ferry bridge 3 further includes one or more rotation support pairs 34, which are arranged on the main longitudinal beam 32 and at both ends of the main longitudinal beam 32. The main longitudinal beams 32 are connected through the rotation support pairs 34, and the ferry bridge 3 is placed in the pit 11. The rotation support pairs 34 support the main support seat 31, so that the ferry bridge 3 can be stably placed in the pit 11 of the shore foundation 1, and the ferry bridge 3 can have the freedom of lateral rotation relative to the shore foundation 1.

[0046] like Figure 8 As shown, an optional implementation is that a sliding track 311 is provided in the middle of the main body support seat 31 , and a swing balancing slider 312 is provided on the sliding track 311 , and the sliding direction of the swing balancing slider 312 is perpendicular to the direction of the main longitudinal beam 32 .

[0047] like Figure 1 , Figure 2 As shown, an optional implementation is that a third track 331 is provided on the upper surface of the main beam 33 for docking with the first track 12 provided on the surface of the shore base 1 and the second track 21 provided on the surface of the lifting platform 2 .

[0048] like Figure 2 As shown, the two ends of the main beam 33 are respectively embedded in the first groove 13 provided on the surface of the shore 1 and the second groove 22 provided on the surface of the lifting platform 2. The ferry bridge 3 is placed in the pit 11, and the two ends of the main beam 33 on the ferry bridge 3 face the shore 1 and the lifting platform 2. The two ends of the main beam 33 are respectively embedded in the first groove 13 of the shore 1 and the second groove 22 of the lifting platform 2, so that the ferry bridge 3 can be stably embedded in the pit 11 in the shore 1, and at the same time, the third track 331 on the main beam 33 can be stably connected with the first track 12 and the second track 21 without step.

[0049] like Figure 4As shown, an optional implementation is that a first limiting rubber 332 is provided on the lower surface of the main beam 33 located at both ends of the main support seat 31, and a second limiting rubber 333 is provided on the surface of the first groove 13 and the surface of the second groove 22 at corresponding positions on the main beam 33.

[0050] like Figure 7 , Figure 8 As shown, an optional implementation is that a hydraulic cylinder 313 is provided on the swing balancing slider 312 to drive the swing balancing slider 312 to slide on the sliding track 311. In this implementation, the hydraulic cylinder 313 is used to drive the swing balancing slider 312 as an example. Cylinder drive, motor drive and other driving methods can be used, and the driving method is not limited to this.

[0051] like Figure 2 As shown, an optional implementation is that the upper surface of the ferry bridge 3 is at the same horizontal position as the upper surface of the shore foundation 1. The ferry bridge 3 is arranged at the joint between the lifting platform 2 and the shore foundation 1.

[0052] In this embodiment, a pit 11 with a size larger than the ferry bridge 3 is designed at the shore 1 for placing the ferry bridge 3, so that the upper surface of the ferry bridge 3 and the upper surface of the shore 1 are at the same horizontal position, so that the walking transfer trolley 4 can smoothly transition from the lifting platform 2 to the shore 1. The process of the walking transfer trolley 4 transporting the ship 5 through the ferry bridge 3 in and out of the lifting platform 2 is as follows: the ferry bridge 3 is designed with a main beam 33, and the upper surface of the main beam 33 is provided with a third track 331, which can be connected to the first track 12 and the second track 21 without stepping, so that the walking transfer trolley 4 can slide and move smoothly on the shore 1 and the lifting platform 2. When the walking transfer trolley 4 moves from the shore 1 to the lifting platform 2, the swing balance slider 312 is driven by the hydraulic cylinder 313 to move horizontally in the ferry bridge 3 along the sliding track 311. The swing balance slider 312 is pushed to the side of the shore 1 along the sliding track 311, and then the ferry bridge 3 is swung to the side of the shore 1. The first limiting rubber 332 on the lower surface of the end of the main crossbeam 33 overlaps with the second limiting rubber 333 at the corresponding position on the first groove 13 of the shore 1, and the third track 331 on the main crossbeam 33 of the ferry bridge 3 is stably docked with the first track 12 on the shore 1. The overlapping cooperation of the first limiting rubber 332 and the second limiting rubber 333 plays a buffering role to a certain extent. Therefore, the walking transfer trolley 4 can smoothly travel along the first track 12 of the shore 1 to the ferry bridge 3 and move along the third track 331 on the ferry bridge 3. The walking transfer trolley 4 moves to the ferry bridge 3 and travels from the shore 1 end to the lifting platform 2 end. Since the weight of the ship 5 distributed on the walking transfer trolley 4 is much greater than the weight of the swing balance slider 312, when traveling through the longitudinal center line of the ferry bridge 3 (i.e., the main longitudinal beam 32 rotation axis), the ferry bridge 3 swings to the side of the lifting platform 2. The weight of the ship 5 is transferred from the walking transfer trolley 4 to the lifting platform 2 side of the rotation axis of the ferry bridge 3. Since the force transmitted from the walking transfer trolley 4 to the ferry bridge 3 is basically unchanged during the process of the walking transfer trolley 4 moving from the longitudinal axis of the ferry bridge 3 to the lifting platform 2, the distance relative to the rotation axis is gradually increasing. That is, the force arm of the transmission force is gradually increasing. Therefore, during the process of the walking transfer trolley 4 moving from the longitudinal axis of the ferry bridge 3 to the lifting platform 2, the force of the ship 5 distributed on the trolley is transferred to the lifting platform 2 through the ferry bridge 3, which is a gradually increasing process, and the deformation of the lifting platform 2 is also a gradually increasing process. At the same time, when the ferry bridge 3 swings, the walking transfer trolley 4 is located near the swing fulcrum of the swing balance slider 312, and the swing arc of the swing balance slider 312 is also close to zero. The above process ensures that a group of walking transfer trolleys 4 travels smoothly from the shore 1 to the lifting platform 2. When the previous group of walking transfer trolleys 4 travels smoothly from the ferry bridge 3 to the lifting platform 2, the ferry bridge 3 automatically swings back to the shore 1 side because the swing balance slider 312 is close to the shore 1 side. The latter group of walking transfer trolleys can smoothly drive onto the ferry bridge 3 until all the trolleys drive onto the lifting platform 2.When the walking transfer trolley 4 of the shipping vessel 5 is to move from the lifting platform 2 to the shore 1, the swing balance slider 312 slides along the sliding track 311 to the side close to the lifting platform 2, and the ferry bridge 3 is connected to the lifting platform 2 first. The walking transfer trolley 4 can smoothly move from the lifting platform 2 to the shore 1 through the above reverse process.

[0053] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
