Description

Technical Field

[0001] The utility model relates to the technical field of dock approach bridges, in particular to a floating dock follower approach bridge. Background Art

[0002] In the existing port and wharf construction, cargo transfer between the floating dock and the shore usually requires the use of fixed or movable approach bridges. In the traditional method, fixed approach bridges are mostly used. They have a simple structure but limited applicability and cannot adapt to large changes in water levels. As a result, the gap between the ship and the approach bridge is too large or too small at high tide or low tide, affecting the efficiency and safety of cargo loading and unloading. In addition, although the movable approach bridge can adapt to changes in water levels, its structure is complex and the maintenance cost is high. In addition, there are still efficiency problems caused by slow response speed during use.

[0003] The Chinese patent with the announcement number CN218027471U discloses a floating dock follower approach bridge, which includes a fixed ladder arranged on the upper part of the slope and connected to the road on the top of the slope, characterized in that the fixed ladder is connected to a pontoon arranged on the water surface through a floating approach bridge, and the upper end of the floating approach bridge is connected to the fixed ladder through a first hinge mechanism, and the lower end is connected to the pontoon through a second hinge mechanism. The floating pontoon in the water and the fixed ladder on the shore are effectively connected through the floating approach bridge, and the first and second hinge mechanisms are used to change the swing angle of the floating approach bridge when the pontoon rises or falls with the water level, thereby realizing the unpowered automatic adjustment of the angle between the floating approach bridge and the pontoon, ensuring the connection stability between the pontoon and the fixed ladder, and solving the problems of excessive deadweight, difficult maintenance, and high construction cost brought by traditional approach bridges.

[0004] Based on the above search and combined with the prior art, we found that:

[0005] The existing device changes the swing angle of the floating approach bridge through the first and second hinged mechanisms when the pontoon rises or falls with the water level, thereby realizing unpowered automatic adjustment of the angle of the floating approach bridge and the pontoon, thereby ensuring the connection stability between the pontoon and the fixed step. However, when the water level is low, in order to ensure the connection stability, the angle of the approach bridge is adjusted, which will make the slope of the approach bridge too large, making it difficult for pedestrians or vehicles to move on the approach bridge. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a floating dock follower approach bridge, which can select a suitable depth by observing the water level scale to keep the approach bridge relatively level with the shore. When facing a low water level, a pair of water pumps can be used to pump out the water inside the floating dock body and discharge it to the outside through a drain pipe. At this time, the mass of the floating dock body becomes smaller and can float higher in the water, which can offset the height difference of the water level drop, so that the approach bridge and the shore can still remain relatively level.

[0007] The technical solution to achieve the purpose of this utility model is:

[0008] A floating dock follower approach bridge, comprising:

[0009] A floating dock body, both sides of which are connected to water inlet pipes with valves, the interior of the floating dock body is hollow, a drainage pipe is connected to the floating dock body, a water pumping device is installed inside the floating dock body, and the water pumping device is connected to the drainage pipe;

[0010] An approach bridge is rotatably connected to the floating dock body.

[0011] Furthermore, a pair of first steel cables are connected to the approach bridge, a pair of second support plates are installed on the floating dock body, a support column is connected between the pair of second support plates, a pair of pulleys are rotatably connected to the support column, and the pair of first steel cables are respectively wound and connected with the pair of pulleys.

[0012] Furthermore, a pair of first support plates are installed at one end of the floating dock body, a rotating shaft is rotatably connected between the pair of first support plates, and the rotating shaft is fixedly connected to the approach bridge.

[0013] Furthermore, a pair of third support plates are installed on the floating dock body, and a first take-up roller is rotatably connected between the pair of third support plates. A first motor is installed on one of the third support plates, and an output shaft of the first motor is fixedly connected to one end of the first take-up roller. The other ends of a pair of first steel cables are both wound around the first take-up roller.

[0014] Furthermore, the floating dock body is connected with an anchor.

[0015] Furthermore, the floating dock body is installed with a pair of fourth support plates, a second take-up roller is rotatably connected between the pair of fourth support plates, a second motor is installed on one of the fourth support plates, and an output shaft of the second motor is fixedly connected to one end of the second take-up roller.

[0016] Furthermore, a second steel cable is wound around the second take-up roller, and the other end of the second steel cable is connected to the anchor.

[0017] Furthermore, a water level mark is provided on one side of the floating dock body.

[0018] Furthermore, the water-drawing device is a water pump.

[0019] Furthermore, each of the water pumps is connected to a transport pipe, and the other end of the transport pipe is connected to a drainage pipe.

[0020] Compared with the prior art, the present invention has the following significant advantages:

[0021] First, in the present invention, when the water level is deep, a pair of water inlet pipes with valves can be opened to allow water to flow into the main body of the floating dock, so that the main body of the floating dock becomes heavier and sinks deeper in the water. The water level scale can be observed to select a suitable depth to keep the approach bridge relatively level with the shore. When the water level is low, a pair of water pumps can be used to pump out the water inside the main body of the floating dock and discharge it to the outside through a drainage pipe. At this time, the main body of the floating dock becomes lighter and can float higher in the water, thus offsetting the height difference of the water level drop, so that the approach bridge and the shore can still remain relatively level.

[0022] Secondly, in the utility model, when the approach bridge occupies the waterway and needs to be avoided, the first steel cable can be tightened to pull the approach bridge upward to avoid the sailing ship. After the ship passes, the approach bridge can be lowered and can continue to be used. The device drives the second take-up roller to rotate through the second motor to realize the retraction and release of the anchor. The anchor can ensure the stability of the main body of the floating dock and prevent the main body of the floating dock from shifting due to excessive wind and waves.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides a floating dock follower approach bridge through improvement. The technical solution of the utility model is:

[0030] As shown in the figure and Figure 2 As shown, a floating dock follower approach bridge includes a floating dock body 1, both sides of the floating dock body 1 are connected with water inlet pipes 2 with valves, the interior of the floating dock body 1 is hollow, a pair of drainage pipes 3 are connected to the floating dock body 1, a pair of water pumps 4 are installed inside the floating dock body 1, the pair of water pumps 4 are connected with transport pipes 5, the other ends of the pair of transport pipes 5 are respectively connected with the pair of drainage pipes 3, and a water level scale line 6 is arranged on one side of the floating dock body 1.

[0031] When in use, when the water level is deep, a pair of water inlet pipes 2 with valves can be opened to allow water to flow into the floating dock body 1, so that the mass of the floating dock body 1 increases and the depth of sinking in the water increases. By observing the water level scale line 6, a suitable depth can be selected to keep the approach bridge 9 relatively level with the shore. When facing a low water level, a pair of water pumps 4 can be used to pump out the water inside the floating dock body 1 and discharge it to the outside through the drain pipe 3. At this time, the mass of the floating dock body 1 decreases and it can float higher in the water, thus offsetting the height difference of the water level drop.

[0032] like Figure 1 As shown, a pair of first support plates 7 are installed at one end of the floating dock body 1, a rotating shaft 8 is rotatably connected between the pair of first support plates 7, an approach bridge 9 is fixedly installed on the rotating shaft 8, a pair of first steel cables 10 are connected to the approach bridge 9, a pair of second support plates 11 are installed on the floating dock body 1, a support column 12 is connected between the pair of second support plates 11, a pair of pulleys 13 are rotatably connected to the support column 12, and the pair of first steel cables 10 are movably connected to the pair of pulleys 13 respectively.

[0033] like Figure 3As shown, a pair of third support plates 14 are installed on the main body 1 of the floating dock, and a first take-up roller 15 is rotatably connected between the pair of third support plates 14, and a first motor 16 is installed on one of the third support plates 14, and the output shaft of the first motor 16 is fixedly connected to one end of the first take-up roller 15, and the other ends of a pair of first steel cables 10 are both wound around the first take-up roller 15, and the approach bridge 9 is pulled upward to avoid the sailing ship by tightening the first steel cable 10, and the approach bridge 9 can be lowered after the ship passes and can continue to be used. Specifically, the first motor 16 drives the first take-up roller 15 to rotate, and the first steel cable 10 can be loosened or tightened. When the approach bridge 9 occupies the waterway and needs to be avoided, the first steel cable 10 can be tightened to pull the approach bridge 9 upward to avoid the sailing ship, and the approach bridge 9 can be lowered after the ship passes and can continue to be used.

[0034] In this embodiment, the approach bridge 9 is fixed to the rotating shaft 8 and connected to the floating dock body 1 through a pair of first support plates 7. The height of the approach bridge 9 changes with the water inflow and outflow of the floating dock body 1. The approach bridge 9 and the shore can still be kept relatively level, thus avoiding the problem that pedestrians or vehicles are difficult to move on the approach bridge 9 due to the large slope of the approach bridge 9.

The anchor 21 can ensure the stability of the floating dock body 1 and prevent the floating dock body 1 from shifting due to excessive wind and waves. The second motor 19 drives the second take-up roller 18 to rotate, so as to realize the retraction and release of the anchor 21. The anchor 21 can ensure the stability of the floating dock body 1 and prevent the floating dock body 1 from shifting due to excessive wind and waves.
