Description

Technical Field

[0001] The invention relates to the technical field of temporary high-pile docks, in particular to a temporary high-pile dock bottom plate supporting structure. Background Art

[0002] A high-pile wharf is composed of the superstructure (pile platform or cap), pile foundation, shore connection structure, shore lock and wharf equipment. The superstructure constitutes the wharf surface and is connected to the pile foundation as a whole. It directly bears the vertical and horizontal loads acting on the wharf surface and transfers them to the pile foundation. The pile foundation is used to support the superstructure and transfer the load of the superstructure and wharf surface to the deep foundation. It is also conducive to stabilizing the shore slope.

[0003] Temporary high-pile docks are often used in flood seasons when the water level is unstable to temporarily transport necessary materials such as rescue supplies. The preset depth of the pile foundation is limited and the bearing capacity is weak, but it is easy to set up and dismantle, and has a certain degree of convenience. This leads to the uncertainty of the impact height of the ship on the pile foundation of the temporary high-pile dock under unstable water levels. However, traditional pile foundation supports are all in a certain and fixed position. The uncertainty of the impact height will further lead to unstable deformation caused by horizontal impacts on the pile foundation. On the one hand, it will cause uneven bearing of the pile foundation. If the pile foundation is set with a high-safety saturated load, it will make it more difficult to select materials for the pile foundation and the cost of setting it up will be higher. Secondly, the pile foundation will also cause the bottom plate supported by it to shake significantly due to uneven deformation, affecting safety and the difficulty of setting up the bottom plate.

[0034] The locking group includes a lifting plate 11, and a plurality of sleeves 12 are slidably connected to the bottom of the lifting plate 11. The sleeves 12 are hollow inside and have a through hole 13 at the bottom. Second air bags 14 are arranged inside the sleeves 12, and the second air bags 14 are located below the lifting plate 11. The sleeves 12 are fixedly connected to the driving plate 6. The front and rear ends of the lifting plate 11 are fixedly connected to a pull rope 15, and the bottom ends of the pull ropes 15 are fixedly connected to a retracting rod 16. The two retracting rods 16 are respectively slidably connected to the inside of the two telescopic rods 8. A first spring 17 is fixedly connected between the two telescopic rods 8 and the two retracting rods 16. The bottom end of each telescopic rod 8 is slidably connected to two connecting members 18, and the two connecting members 18 are rotatably connected to gears 19, and the gears 19 are meshed with rack rods 32, and the rack rods 32 are fixedly connected to the inner wall of the top rod 9. A one-way bearing is provided on the rotating shaft of the gear 19, and the one-way bearing is used to enable the gear 19 to rotate in only one direction. A second spring 20 is fixedly connected between the connecting member 18 and the inner wall of the retractable rod 16, and a contact block 21 is provided between the two connecting members 18. The contact block 21 is fixedly connected to the bottom end of the retractable rod 16, and the front and rear side walls of the contact block 21 are provided with inclined surfaces.

[0035] like Figure 1-Figure 5 As shown:

[0036] The bottom ends of several foundation piles 4 are inserted into the water outside the port, and the fixing plate 1 is fixed on the shore. At this time, the frame plate 2 and the bottom plate 3 can be erected above the water surface through the fixing plate 1 and the foundation piles 4. There are multiple bottom plates 3, which can be evenly laid on the frame plate 2, which is convenient for installation and disassembly. The fixing rod 10 and the force rod 26 are both under the water surface and cannot be moved. At this time, the installation of the high-pile dock can be completed, and the first airbag 7 is floating on the water surface, and the driving plate 6 is slightly under the water surface. Therefore, when the water surface changes, the driving plate 6 and the first airbag 7 will rise or fall with the water surface;

[0037] When working at a high-pile dock, ships carrying out transshipment or other work will approach the frame plate 2 and the bottom plate 3, and the foundation piles 4 will inevitably be collided (the ship itself needs to collide with the foundation piles 4 to dock, and the collision force is from left to right). At this time, the foundation piles 4 will shake and tilt, which will affect the stability of the frame plate 2 and the bottom plate 3;

[0038] When the pile 4 is hit, the pile 4 will tend to tilt, and at this time the pile 4 will drive the driving plate 6 and the telescopic rod 8 to move to the right, and the top rod 9 is restricted by the fixed rod 10 and the force rod 26 and cannot move, and the telescopic rod 8 is slidably connected to the top rod 9, so at this time the locking group will restrict the sliding of the telescopic rod 8 and the top rod 9, so that the telescopic rod 8 cannot slide along the top rod 9, then when the pile 4 is hit and tilted, the telescopic rod 8 and the top rod 9 will provide lateral support to the pile 4 under the support provided by the fixed rod 10 and the force rod 26, and then resist the collision force of the pile 4, so as to prevent the pile 4 from tilting and shaking, which will affect the stability of the frame plate 2 and the bottom plate 3;

[0039] And the first airbag 7 is always floating on the water surface, so when the water level changes, the first airbag 7 and the driving plate 6 will rise and fall with the water level. At this time, the driving plate 6 will slide along the foundation pile 4 in the vertical direction with the height of the water surface. When the driving plate 6 slides, it will drive the top rod 9 to rotate around the rotating shaft on the fixed rod 10 through the telescopic rod 8. At this time, the telescopic rod 8 will also slide inside the top rod 9 and self-lock after sliding, so that the driving plate 6 and the telescopic rod 8 can automatically change when the water surface height changes, so that the telescopic rod 8 and the top rod 9 can be supported at different positions when the water surface height changes. For example, when the water surface height is high, the foundation pile 4 is subjected to The collision position will become higher, and the collision point of the relative foundation pile 4 will be farther away from the supporting position of the bottom of the foundation pile 4 inside the soil at the bottom of the water outside the port, and the corresponding foundation pile 4 will be more prone to tilting. The first airbag 7 can control the position height of the telescopic rod 8 and the top rod 9 when the water level changes, so that the support points of the telescopic rod 8 and the top rod 9 are always near the collision point of the foundation pile 4, which will provide relatively more stable support. When the water level is low, the telescopic rod 8 and the top rod 9 will also change their positions according to the water level, so that the support point and the collision point are automatically adapted to ensure the stability of the high-pile dock.

[0040] Moreover, when the foundation pile 4 tilts, the top of the foundation pile 4 will slide along the arc surface of the bottom of the support block 5 and continue to maintain contact with the arc surface of the bottom of the support block 5, so that when the foundation pile 4 rotates and tilts, it will continue to support the frame plate 2 and the bottom plate 3, so that the frame plate 2 and the bottom plate 3 will not tilt and will not affect the normal load-bearing work;

[0041] like Figure 6-Figure 11 As shown:

[0042] The locking group works as follows:

[0043] When the water level is at a fixed height, Figure 6When the water is at the middle point c, the first airbag 7 is always floating on the water surface, and the driving plate 6 is below the water surface c, then the sleeve 12 is immersed below the water surface, and when the river water enters the sleeve 12 through the through hole 13, the second airbag 14 will be pushed up, so that the second airbag 14 is at the highest point inside the sleeve 12, then multiple second airbags 14 will push up the lifting plate 11, so that the lifting plate 11 is at the highest position, at this time the lifting plate 11 will pull the pull rope 15 to the limit position, and then the pull rope 15 will pull the retracting rod 16 and the contact block 21 to slide along the telescopic rod 8 to the limit, at this time the contact block 21 will push the two connecting members 18 to both sides through the inclined surface of the side wall, and at this time the second spring 20 will will be compressed, and the gear 19 will mesh with the rack rod 32. Since the gear 19 can only rotate in one direction, the elastic reset effect of the first spring 17 or the gravity of the retracting rod 16 itself will not drive the gear 19 to slide downward. At this time, the gear 19 will be locked in this position. Then, when the pile 4 is hit, it will be firmly supported by the telescopic rod 8 and the top rod 9. Since the gear 19 can only move when the retracting rod 16 and the telescopic rod 8 slide to the left along the top rod 9, if the water surface continues to rise to above point C, the first airbag 7 will rise and drive the driving plate 6 and the telescopic rod 8 to rise. At this time, the retracting rod 16 and the gear 19 will move to the left inside the top rod 9, and then automatically adapt.

[0044] However, if the water surface drops from point c to point d or point e:

[0045] When the water level drops to a level that is not high enough to float the second airbag 14 or is not at the highest position, the second airbag 14 will descend inside the sleeve 12 and drive the lifting plate 11 to descend. At this time, the pull rope 15 will also be driven and straightened by the retracting rod 16 and the reset action of the first spring 17. At this time, the retracting rod 16 will slide a certain distance toward the inside of the top rod 9, and at this time, the contact block 21 may move to a position where the connecting member 18 cannot contact the gear 19 and the rack rod 32. At this time, the driving plate 6 will automatically slide down under the action of its own gravity until the driving plate 6 continues to sink below the water surface. The second airbag 14 will lift the lifting plate 11 again. At this time, the lifting plate 11 will pull the retracting rod 16 again, thereby causing the contact block 21 to push the connecting member 18 again to engage the gear 19 with the rack rod 32. At this time, the sliding of the telescopic rod 8 and the top rod 9 can be locked again to ensure the continuation of the support work for the foundation pile 4.

[0046] If the water level drops from point d to point e, the principle is the same as the water level dropping from point c to point d;

[0047] The present invention can control the position height of the telescopic rod 8 and the top rod 9 through the first airbag 7 when the water surface height changes, so that the supporting points of the telescopic rod 8 and the top rod 9 are always near the collision point of the foundation pile 4, which will provide relatively more stable support, and then the positions of the supporting point and the collision point are automatically adapted, ensuring the stability of the high-pile wharf.

[0048] Two slide grooves 22 are provided on the fixed plate 1, and the two slide grooves 22 are slidably connected with a plug plate 23. The plug plate 23 is rotatably connected to the fixed plate 1, and the plug plate 23 is fixedly connected to the river bank through an anchor rod. The slide grooves 22 are all arc-shaped, and positioning grooves 24 are provided at positions corresponding to the tops of the foundation piles 4 on the support blocks 5. The tops of the foundation piles 4 are rotatably connected with positioning blocks 25. The positioning blocks 25 are respectively located in the positioning grooves 24 above them, and the force rods 26 are fixedly connected to the bottom of the plug plate 23.

[0049] like Figure 3 as well as Figure 5 As shown:

[0050] Fixing the plug plate 23 to the shore by means of anchor rods or larger fixing pins can provide a firm support for the force-bearing rod 26 in the water, thereby improving the stability of the support for the fixing plate 1. When the foundation pile 4 is hit from the left side, the foundation pile 4 may experience a small forward and backward shaking. When the foundation pile 4 deviates forward and backward, the fixing plate 1, the frame plate 2 and the bottom plate 3 will all rotate. At this time, the fixing plate 1 will rotate around the rotation axis on the plug plate 23. At this time, the two slide grooves 22 will slide slightly along the sliding end on the plug plate 23 to offset the deviation of the frame plate 2, and the center point of the slide groove 22 is the rotation axis of the fixing plate 1. When the frame plate 2 rotates, the positioning block 25 will slide along the positioning groove 24, and the positioning block 25 can follow the inclination angle of the frame plate 2 and rotate slightly on the foundation pile 4, thereby adapting to the deflection in the forward and backward directions.

[0051] An arc groove is provided on the fixed rod 10, the top end of the fixed rod 10 is slidably connected to the frame plate 2, the arc groove is slidably connected to the force-bearing rod 26, the side wall of the driving plate 6 is arc-shaped and its side wall is slidably connected to a cross plate 27, the cross plate 27 is slidably connected to a plurality of foundation piles 4, and the driving plate 6 is slidably connected to the foundation piles 4 through the cross plate 27.

[0052] like Figure 7 as well as Fig.12 As shown:

[0053] When the frame plate 2 deflects in the front-back direction, the frame plate 2 will drive the fixed rod 10 to rotate together, and the center point of the arc groove on the fixed rod 10 coincides with the rotation axis of the fixed plate 1. Note that at this time, the fixed rod 10 will slide along the sliding end on the force-bearing rod 26 and drive the top rod 9 and the telescopic rod 8 to rotate together. At this time, the driving plate 6 will slide along the cross plate 27 while following the movement of the telescopic rod 8, while the cross plate 27 maintains contact with the foundation pile 4 and does not change.

[0054] At this time, the frame plate 2 and the bottom plate 3 will be slightly tilted, so the position of the subsequent ship will change slightly when it docks, and the direction of the collision of the pile 4 will be slightly changed. At this time, the position of the telescopic rod 8 and the top rod 9 will also change accordingly, and then the cross plate 27 can ensure the consistency of the collision of multiple piles 4, without hindering the normal load-bearing work of the frame plate 2 and the supporting work of the telescopic rod 8 and the top rod 9.

[0055] A connecting rod 28 is fixedly connected between the two push rods 9 .

[0056] like Figure 4 and Fig. 9 As shown:

[0057] The two top rods 9 are made into a whole by the connecting rod 28, thereby ensuring the consistency of support and rotation.

[0058] Limiting plates 29 are fixedly connected to both left and right side walls of the support block 5 .

[0059] like Figure 1 and Figure 2 As shown:

[0060] The limiting plate 29 can provide a stable limitation of the inclination of the foundation pile 4 beyond a maximum extent.

[0061] A guide wheel 30 is provided on one side of the two pull ropes 15 . The two guide wheels 30 are rotatably connected to the side walls of the two telescopic rods 8 , and the two guide wheels 30 are in contact with the two pull ropes 15 , respectively.

[0062] like Figure 7 and Fig.10 As shown:

[0063] The tensioning of the pull cord 15 can be guided by the guide wheel 30 .

[0064] The force bearing rod 26 is threadedly connected to the inserting plate 23 via bolts 31 .

[0065] like Fig.12 As shown:

[0066] The bolts 31 facilitate installation and disassembly of the force-bearing rod 26 .
