Description

Technical Field

[0001] This invention relates to the field of elevated trestle platform technology, specifically a self-propelled and self-elevating elevated trestle platform. Background Technology

[0002] While constructing and assembling floating structures on water is relatively convenient and quick, their wave adaptability is limited. Elevated structures, being a certain height above the water surface, are no longer subject to wave loads, effectively improving their wave resistance. However, the construction workload is relatively large, especially in shallow waters where large construction vessels cannot access the area, making construction difficult. Furthermore, in open ocean environments without power supply, rapid construction of elevated structures is impossible, leading to inconvenience in installing the elevated pier platform. Moreover, once installed, the elevated pier platform cannot be raised or moved, resulting in certain limitations. Therefore, we propose a self-propelled, self-elevating elevated pier platform to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a self-propelled and self-elevating elevated trestle platform to solve the problems mentioned in the background art, such as the inconvenience of installing the elevated trestle platform and the inability to raise or move it after installation, which leads to certain limitations of the elevated trestle platform.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a self-propelled and self-elevating elevated trestle platform, comprising a hull for installing the elevated trestle platform;

[0005] The ship has four sets of pile legs, which are movably installed at both ends of the hull.

[0006] An active platform component, which is fixedly installed on the hull, is used to extend and retract when a crane lifts the elevated trestle platform.

[0007] A connecting component is fixedly installed on the front end of the hull and is connected to the front, rear, left and right sides of the movable platform component. The connecting component is used to improve the fastening and support function when the movable platform is deployed.

[0008] A transmission component is fixedly installed on the movable platform component and the connecting component. The transmission component is used to drive the connecting component to stretch and unfold when the movable platform component is unfolded.

[0009] A clamping assembly is disposed on the movable platform assembly and is used to fix a crane or some large machinery on the movable platform assembly.

[0010] Preferably, the active platform assembly includes a mounting plate and an active plate. The mounting plate is fixedly mounted on the hull, and the active plate is movably inserted into the mounting plate. The lower sides of both ends of the active plate are provided with toothed grooves. Gears are rotatably mounted inside the front sides of both ends of the mounting plate. Two sets of gears mesh with the toothed grooves. A first rotating shaft is rotatably mounted between the two sets of gears. A bidirectional motor is fixedly mounted on the first rotating shaft, and the bidirectional motor is mounted inside the mounting plate.

[0011] Preferably, the connecting assembly includes a second rotating shaft, which is rotatably mounted in the hull. Two coils are fixedly mounted on both ends of the second rotating shaft. The two coils rotate within the hull, and ropes are wound around them. Two sets of uprights are fixedly mounted on the front end of the hull. Each set of uprights has a movable groove, and the upper ends of the two sets of ropes are movably inserted into these grooves. The two sets of ropes are fixedly connected to the front end of a movable plate.

[0012] Preferably, pulleys are rotatably installed at the upper ends of both sets of columns, and the arc-shaped grooves on the pulleys are in contact with the ropes.

[0013] Preferably, the transmission assembly includes a first synchronous pulley and a second synchronous pulley, the first synchronous pulley is fixedly mounted on a first rotating shaft, the second synchronous pulley is fixedly mounted on a second rotating shaft, and a synchronous belt is sleeved on the first synchronous pulley and the second synchronous pulley.

[0014] Preferably, the first synchronous pulley and the second synchronous pulley are respectively installed on the mounting plate and in the hull, and the diameters of the first synchronous pulley and the second synchronous pulley are the same.

[0015] Preferably, the clamping assembly includes two sets of grooves, which are formed on the left and right ends of the movable plate. A first baffle is fixedly installed on the opposite side of the two sets of grooves. Two sets of first sliding grooves are formed on the lower side of the adjacent ends of the two sets of grooves. A slider is slidably installed in the four sets of first sliding grooves. Two sets of second baffles are fixedly installed on the four sets of sliders. Two sets of connecting rods are fixedly installed at the front and rear ends of the opposite side of the two sets of second baffles. The connecting rods are movably inserted into the first baffles. Four sets of hydraulic rods are symmetrically installed on the left and right sides of the movable plate. The four sets of hydraulic rods are fixedly connected to the two sets of second baffles respectively.

[0016] Preferably, the upper side of the mounting plate is provided with symmetrical second sliding grooves, and the protrusion on the lower rear end of the movable plate slides within the two sets of second sliding grooves.

[0017] Preferably, the inner walls of the two sets of first slide grooves and the two sets of second slide grooves, as well as the protrusions on the lower rear end of the two sets of sliders and movable plates, are all T-shaped.

[0018] The beneficial effects of the present invention are: when some large instruments are fixed on the movable plate, the present invention drives the second baffle to move through the hydraulic rod, so that the second baffle drives the connecting rod to be inserted into the first baffle. The first baffle and the second baffle are fixed on the movable plate close to the wheels of the instruments, thereby preventing the large instruments from moving on the movable plate when the hull moves.

[0019] During hoisting, a bidirectional motor drives two sets of gears to rotate, which in turn causes the movable plate to slide out from the mounting plate. This allows large machinery fixed on the movable plate to extend and slide out from the hull, enabling the use of large machinery for hoisting without the pile legs obstructing the machinery, thus improving the convenience of hoisting. Furthermore, as the bidirectional motor rotates, it drives the gears to rotate, which in turn drives two sets of cable reels to rotate. The rotation of the two sets of cable reels extends the ropes, which connects and supports the sliding movable plate, preventing instability and poor support during the sliding process.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-8 The present invention provides an embodiment of a self-propelled and self-elevating elevated trestle platform, comprising a hull 1 for installation of the elevated trestle platform;

[0032] Leg 2, there are four sets of leg 2, and the four sets of leg 2 are movably installed inside the left and right ends of the hull 1;

[0033] The movable platform component is fixedly installed on the hull 1. The movable platform component is used for the crane to extend and retract when lifting the elevated trestle platform.

[0034] The connecting component is fixedly installed on the front end of the hull 1. The connecting component is connected to the front, rear, left and right sides of the movable platform component. The connecting component is used to improve the fastening and support when the movable platform is deployed.

[0035] A transmission component is fixedly installed on the movable platform component and the connecting component. The transmission component is used to drive the connecting component to stretch and unfold when the movable platform component is unfolded.

[0036] The clamping assembly is mounted on the movable platform assembly. The clamping assembly is used to fix cranes or some large machinery on the movable platform assembly. This device fixes the large machinery to the movable platform assembly through the clamping assembly. Then, the large machinery is slid out from the hull 1 by sliding the movable platform assembly, so that the large machinery has a certain amount of room to move when in use. Then, when the movable platform assembly is unfolded, the connecting assembly is pulled out by the transmission assembly, thereby connecting and supporting the movable platform assembly when it slides out.

[0037] Furthermore, the mobile platform component includes a mounting plate 3 and a movable plate 4. The mounting plate 3 is fixedly mounted on the hull 1, and the movable plate 4 is movably inserted into the mounting plate 3. The lower sides of both the left and right ends of the movable plate 4 are provided with toothed grooves 5. Gears 6 are rotatably mounted inside the front sides of both the left and right ends of the mounting plate 3. Two sets of gears 6 mesh with the toothed grooves 5. A first rotating shaft 7 is rotatably mounted between the two sets of gears 6. A bidirectional motor 8 is fixedly mounted on the first rotating shaft 7. The bidirectional motor 8 is installed inside the mounting plate 3. This structure drives the first rotating shaft 7 and the two sets of gears 6 to rotate through the bidirectional motor 8, so that the rotation of the two sets of gears 6 causes the movable plate 4 to slide out from the mounting plate 3, allowing large machinery to slide out from inside the hull 1. When using large machinery for hoisting, this avoids collisions between the machinery and the pile legs 2 during rotation.

[0038] Furthermore, the connecting assembly includes a second rotating shaft 9, which is rotatably installed inside the hull 1. Two sets of reels 10 are fixedly installed on both the left and right ends of the second rotating shaft 9. The two sets of reels 10 rotate inside the hull 1, and ropes 11 are wound around the two sets of reels 10. Two sets of uprights 12 are fixedly installed on the front end of the hull 1. Each set of uprights 12 has a movable groove 13. The upper ends of the two sets of ropes 11 are movably inserted into the movable grooves 13. The two sets of ropes 11 are fixedly connected to the front end of the movable plate 4. This structure, through the rotation of the second rotating shaft 9, drives the two sets of reels 10 to rotate, thereby pulling the ropes 11 out from the two sets of reels 10 and extending them, so that the ropes 11 connect to the front end of the movable plate 4, thus supporting the movable plate 4.

[0039] Furthermore, pulleys 14 are rotatably installed inside the upper ends of both sets of columns 12. The arc-shaped grooves on the pulleys 14 fit with the rope 11. This structure, through the pulleys 14 inside the two sets of columns 12, prevents the rope 11 from rubbing against the inner wall of the column 12 and breaking when the rope 11 slides inside the column 12.

[0040] Furthermore, the transmission assembly includes a first synchronous pulley 15 and a second synchronous pulley 16. The first synchronous pulley 15 is fixedly mounted on the first rotating shaft 7, and the second synchronous pulley 16 is fixedly mounted on the second rotating shaft 9. A synchronous belt 17 is sleeved on the first synchronous pulley 15 and the second synchronous pulley 16. The rotation of the first synchronous pulley 15 mounted on the first rotating shaft 7 drives the rotation of the second synchronous pulley 16 mounted on the second rotating shaft 9 through the synchronous belt 17. This causes the movable plate 4 to slide and drive the winding reel 10 to rotate, thereby extending the rope 11 on the winding reel 10.

[0041] Furthermore, the first synchronous pulley 15 and the second synchronous pulley 16 are respectively installed in the mounting plate 3 and the hull 1. The diameters of the first synchronous pulley 15 and the second synchronous pulley 16 are the same. Based on the size of the first synchronous pulley 15 and the second synchronous pulley 16, this structure causes the first rotating shaft 7 to rotate, driving the second rotating shaft 9 to rotate synchronously, so that the movable plate 4 slides out and the rope 11 extends synchronously.

[0042] Furthermore, the clamping assembly includes two sets of grooves 18, which are formed on the left and right ends of the movable plate 4. A first baffle 19 is fixedly installed on the opposite side of each of the two sets of grooves 18. Two sets of first sliding grooves 20 are formed on the lower side of the adjacent ends of each of the two sets of grooves 18. Sliding blocks 21 are slidably installed within the four sets of first sliding grooves 20. Two sets of second baffles 22 are fixedly installed on the four sets of sliding blocks 21. Two sets of connecting rods 23 are fixedly installed at the front and rear ends of the opposite sides of the two sets of second baffles 22. The connecting rods 23 are movably inserted into the first baffles 19. Inside, four sets of hydraulic rods 24 are symmetrically installed on the left and right sides of the movable plate 4. The four sets of hydraulic rods 24 are fixedly connected to two sets of second baffles 22 respectively. This structure drives the two sets of second baffles 22 to slide through the four sets of hydraulic rods 24, so that the two sets of second baffles 22 drive the connecting rods 23 to move and insert into the two sets of first baffles 19. The second baffles 22 and the first baffles 19 are close to and attached to the sides of the wheels or tracks of the large machinery, fixing the large machinery on the movable plate 4 and preventing the large machinery from moving on the movable plate 4 during the movement and causing damage.

[0043] Furthermore, the upper side of the mounting plate 3 is symmetrically provided with second sliding grooves 25. The protrusion on the lower rear end of the movable plate 4 slides within the two sets of second sliding grooves 25. This structure improves the stability of the movable plate 4 sliding within the mounting plate 3 by allowing the rear end of the movable plate 4 to slide within the second sliding grooves 25.

[0044] Furthermore, the inner walls of the two sets of first slide grooves 20 and the two sets of second slide grooves 25, as well as the protrusions on the lower rear ends of the two sets of sliders 21 and the movable plate 4, are all T-shaped. Based on the shape of the inner walls of the two sets of first slide grooves 20 and the two sets of second slide grooves 25, and the protrusions on the lower rear ends of the two sets of sliders 21 and the movable plate 4, this structure ensures that the protrusions on the lower rear ends of the two sets of sliders 21 and the movable plate 4 are sufficiently close to each other when sliding within the inner walls of the two sets of first slide grooves 20 and the two sets of second slide grooves 25, thus preventing the protrusions on the lower rear ends of the two sets of sliders 21 and the movable plate 4 from moving on the inner walls of the two sets of first slide grooves 20 and the two sets of second slide grooves 25.

[0045] Working principle: When large instruments are fixed on the movable plate 4, such as... Figure 4 and Figure 8As shown, the large machinery moves onto the movable plate 4, and then four sets of hydraulic rods 24 extend to drive two sets of second baffles 22 to move within two sets of grooves 18. The movement of the two sets of second baffles 22 drives the connecting rod 23 to move and insert into the first baffle 19. When the two sets of second baffles 22 slide, they drive the slider 21 to slide within the first slide groove 20, so that the second baffles 22 and the first baffles 19 are attached to both sides of the wheel or track, thus fixing the large machinery onto the movable plate 4. After the large machinery is fixed, it can be used for hoisting, as shown in Figure 2. Figure 3 Figure 5 Figure 6 and Figure 7 As shown, the bidirectional motor 8 is started first. The bidirectional motor 8 rotates, driving the first rotating shaft 7 to rotate. The rotation of the first rotating shaft 7 drives the two sets of gears 6 to rotate. The teeth on the two sets of gears 6 roll in the tooth grooves 5, thereby sliding the movable plate 4 from the mounting plate 3. When the movable plate 4 slides forward from the mounting plate 3, the two sets of protrusions on the lower rear end of the movable plate 4 slide in the two sets of second sliding grooves 25, so that the rear end of the movable plate 4 is connected to the mounting plate 3 through the protrusions in the second sliding grooves 25. The movable plate 4 slides out, allowing large machinery to extend from the hull 1 for hoisting. When the movable plate 4 slides out, the first rotating shaft 7 drives the first synchronous pulley. The first synchronous pulley 15 rotates, driving the synchronous belt 17 to rotate. The synchronous belt 17 rotates, driving the second synchronous pulley 16 to rotate. The second synchronous pulley 16 rotates, driving the second rotating shaft 9 to rotate. The second rotating shaft 9 rotates, driving the two sets of winding reels 10 to rotate. The rotation of the two sets of winding reels 10 extends and stretches the rope 11 wound on the winding reels 10, causing the front end of the movable plate 4 to pull out the rope 11. When the movable plate 4 pulls out the rope 11, the rope 11 slides inside the column 12, and the pulley 14 at the upper end of the column 12 moves the rope 11 inside the column 12, avoiding excessive friction between the rope 11 and the column 12. The above is the complete working principle of the present invention.
