Description

Technical Field

[0001] The utility model belongs to the technical field of water surface pipe pile construction, and in particular relates to a platform device for moving, positioning and connecting steel pipe piles in water. Background Art

[0002] In order to meet the bearing capacity requirements of bridges, steel pipe piles are generally designed to be longer and heavier. When constructing steel pipe pile holes in rocks and soil layers in water, the steel pipe piles need to be made in sections, connected in sections, and the steel pipe columns are placed in the soil layer. When the top of the previous section of the steel pipe column is driven near the water surface, the next section of the steel pipe pile is lifted and connected on site with the previous section of the steel pipe pile, and then the connected steel pipe piles are continued to be placed in the soil layer, and so on, until the steel pipe piles are driven to the preset depth.

[0003] At present, there are two ways to carry out steel pipe pile construction on water: setting up a fixed construction platform and using a floating construction platform. The fixed construction platform occupies the waterway, blocks traffic, and affects water transportation. In addition, the fixed construction platform needs to be disassembled and assembled when constructing steel pipe piles in different positions, which can easily cause damage or breakage of the structure and reduce the construction quality of the steel pipe piles. The floating construction platform has poor stability and moves with the water flow and waves, which brings inconvenience to the construction work and also reduces the accuracy of the steel pipe pile construction. Utility Model Content

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a platform device for the underwater mobile positioning and connection of steel pipe piles. The technical problem to be solved by the utility model is how to ensure the stability of the steel pipe pile construction platform device while making the device easy to disassemble or move, so as to improve the construction quality and construction efficiency of the steel pipe piles.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A platform device for moving and positioning steel pipe piles in water, comprising:

[0007] A platform body, a buoy, a driving assembly and several position adjustment assemblies, wherein the buoy floats on the water surface, the platform body is fixed on the several buoys, the platform body is provided with through holes for inserting pipe piles, the driving assembly is installed on the buoy, drives the buoy to move on the water surface, and the position adjustment assembly is connected to the platform body or the buoy, applies driving force to the platform body or the buoy, so that the platform body moves in the opposite direction of the position offset.

[0008] Furthermore, the driving assembly includes a first motor and a first propeller connected to each other, the first motor and the first propeller are installed at the end of the pontoon, and the first propellers installed on different pontoons are on the same side of the platform device.

[0009] Furthermore, the position adjustment component includes a movable anchor, a connecting rope and a winch, the winch is installed on the platform body or the buoy, the movable anchor is set in the water, and the connecting rope connects the winch and the movable anchor.

[0010] Furthermore, the plurality of movable anchors are respectively arranged on a side of the buoy away from the platform body, and at least three of the movable anchors are not in the same straight line.

[0011] Furthermore, the position adjustment component includes a second motor and a second propeller connected to each other, the second motor and the second propeller are installed on the buoy, and a plurality of the second propellers are respectively located in different directions of the platform device.

[0012] Furthermore, the platform body also includes a platform frame and a guide sleeve, and the guide sleeve is arranged in the through hole and connected to the platform frame.

[0013] Furthermore, the platform body is provided with a plurality of inclination sensors.

[0014] Furthermore, a plurality of measuring prisms for measuring verticality are arranged on the outer surface of the guide sleeve.

[0017] Furthermore, a plurality of partitions are provided inside the buoy to divide the interior of the buoy into a plurality of independent compartments, and a water pump is provided at the bottom of each compartment.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. By separately setting the driving assembly and the position adjustment assembly, the platform device can move on the water surface and keep the pipe pile construction position relatively fixed. At the same time, the stability of the platform can be maintained, ensuring the smooth progress of the construction work and improving the quality of the construction. When the next pipe pile construction is carried out, the entire platform can be moved to the corresponding position without disassembly, which improves the construction efficiency;

[0020] 2. There are two ways to adjust the position of the platform device, namely, tightening the platform device through the connecting rope and driving the water flow through the propeller to compensate for the waves. The two methods can be set separately or simultaneously. When the flow rate of river water or sea water is small and the water surface fluctuation is not large, the connecting rope is tightened to fix it, and the wave compensation is fine-tuned; when the flow rate is large, the driving component can make the platform move quickly to the vicinity of the preset end, and then adjust it through wave compensation, tighten the connecting rope to fix it, and complete the rapid reset, so that it can be applied to different wave conditions, different river widths, different navigation requirements, and different water depth conditions;

[0023] 5. The utility model can ensure the accuracy of steel pipe pile docking through multi-means and multi-level adjustments of the platform device position, horizontality and verticality of the guide sleeve, thereby improving the construction quality of the steel pipe piles.

DETAILED DESCRIPTION

[0030] The technical solution of the utility model is clearly and completely described below in conjunction with the accompanying drawings.

[0031] Example 1

[0032] As attached Figure 1-4As shown, this embodiment provides the following technical solutions:

[0033] A platform device for moving and positioning steel pipe piles in water, comprising:

[0034] A platform body 1, a pontoon 2, a driving assembly 3 and a position adjustment assembly 4, wherein the pontoon 2 floats on the water surface, the platform body 1 is fixed on a plurality of the pontoons 2, the platform body 1 is provided with through holes for inserting pipe piles, the driving assembly 3 is installed on the pontoon 2, and drives the pontoon 2 to move on the water surface, and the position adjustment assembly 4 is connected to the platform body 1 or the pontoon 2, and applies a driving force to the platform body 1 or the pontoon 2, so that the platform body 1 moves in the opposite direction of the position offset.

[0035] By separately arranging the driving component 3 and the position adjustment component 4, the platform device can be moved on the water surface and can remain relatively fixed for the pipe pile construction position. At the same time, the stability of the platform can be maintained, thereby ensuring the smooth progress of the construction work and improving the quality of the construction. When the next pipe pile construction is carried out, the entire platform can be moved to the corresponding position without disassembly, thereby improving the construction efficiency.

[0036] Furthermore, the driving assembly 3 includes a first motor and a first propeller 5 connected to each other, the first motor and the first propeller 5 are installed at the end of the buoy 2, and a plurality of the first propellers 5 are on the same side of the platform device.

[0037] Example 2

[0038] The difference from Example 1 is that in this embodiment, as shown in the attached Figure 4 As shown, the position adjustment component 4 includes a mobile anchor 6, a connecting rope 7 and a winch 8, the winch 8 is installed on the platform body 1 or the buoy 2, the mobile anchor 6 is set in the water, and the connecting rope 7 connects the winch 8 and the mobile anchor 6.

[0039] The movable anchors 6 are evenly arranged around the circumference of the platform body 1. When the platform body 1 is offset by wave movement, a number of winches 8 pull the connecting ropes 7 and apply different tensioning forces to the platform device, causing the platform device to move in the direction opposite to the position offset, thereby ensuring the accuracy of the position where the steel pipe piles need to be positioned.

[0040] Furthermore, a plurality of the movable anchors 6 are respectively arranged on a side of the buoy 2 away from the platform body 1, and at least three of the movable anchors 6 are not in the same straight line, so as to ensure that the tensioning forces do not offset each other.

[0041] Example 3

[0042] In Example 2, the mobile anchor 6 is arranged on the periphery of the platform device and is pulled by the connecting rope 7, so it occupies a large space. When the river channel is narrow and the shipping is dense, it will inevitably affect the shipping.

[0043] The difference from Example 2 is that in this embodiment, as shown in the attached Figure 2 , Figure 3 As shown, the position adjustment assembly 4 includes a second motor and a second propeller 9 connected to each other, the second motor and the second propeller 9 are installed on the buoy 2, and a plurality of the second propellers 9 are respectively located in different directions of the platform device;

[0044] When the position of the platform device is offset, the second propeller 9 drives the water flow to exert a force in the opposite direction, so that the platform device returns to its original position;

[0045] Or when there is a force that may cause the platform device to deviate, the second propeller 9 drives the water flow to give a force in the opposite direction to keep the platform device in a fixed position;

[0046] In this embodiment, the platform device for moving and positioning steel pipe piles in water performs wave compensation by driving the water flow through the second propeller 9, thereby reducing the space occupied by the platform device and not affecting the passage of ships in the waterway.

[0047] In addition, it can also be equipped with a control system to perform real-time, automatic wave compensation to ensure accurate positioning of the platform device.

[0050] Furthermore, the platform body 1 is provided with a plurality of inclination sensors.

[0051] By dividing the buoy 2 into a number of independent compartments 202, and providing a water pump at the bottom of each compartment 202, the buoyancy at different positions of the buoy 2 can be adjusted by changing the water level of the compartment 202, thereby adjusting the levelness of the platform body 1;

[0052] Example 5

[0053] The difference from Example 4 is that, as shown in the attached Figure 1-Figure 3As shown, the platform body 1 also includes a platform frame and a guide sleeve 10, wherein the guide sleeve 10 is disposed in the through hole and connected to the platform frame. Through the guide sleeve 10, the steel pipe pile construction is easier to locate and place.

[0054] Furthermore, a plurality of measuring prisms 11 for measuring verticality are arranged on the outer surface of the guide sleeve 10. The measuring prisms 11 collect the real-time verticality of the guide sleeve 10 and compare it with the expected verticality to obtain the deviation distance and deviation direction of the guide sleeve 10.

[0055] Furthermore, the platform body 1 also includes a vertical adjustment device 12, and the vertical adjustment device 12 is connected to the guide sleeve 10 and the skeleton of the platform body 1 respectively.

[0056] In some preferred solutions of this embodiment, the vertical adjustment device 12 includes a plurality of oil cylinders arranged at different heights of the guide sleeve, one end of the oil cylinder is connected to the frame of the platform body 1, and the other end is connected to the guide sleeve 10.

[0057] Even if there is a deviation in the horizontality of the platform body 1, the movement of the oil cylinders at different heights can be controlled according to the deviation distance and deviation direction obtained by measurement and comparison, and the verticality of the guide sleeve 10 can be adjusted, thereby ensuring the docking accuracy and construction quality of the steel pipe piles.

[0058] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes.
