Description

Technical Field

[0001] The utility model relates to the field of mechanical tooling, in particular to a directional removal limiting tooling and a wind measurement tower containing the tooling. Background Art

[0002] With the development of offshore wind power, an increasing number of new offshore wind towers have been erected in operating areas. Almost every offshore wind farm has one or two. Offshore wind towers are typically designed for a service life of three to five years and are approximately 100 meters tall. Once a tower reaches its designed service life, its removal is crucial for maintaining the marine environment, navigation, and fishery production in the operating area.

[0003] However, traditional offshore wind towers are usually dismantled by disassembly or overall dumping. Disassembly has a long construction period, requires large investments in manpower, materials, and machinery, and requires many construction workers to perform high-altitude operations, which is not conducive to production. Overall dumping is difficult to construct and is limited by offshore wind conditions, making it difficult to control the direction of the tower dumping and resulting in high construction risks.

[0004] For example, the invention patent with patent application number CN201210302193.7 specifically discloses a construction method that combines the segmented installation of an offshore wind tower with the assembly of high-altitude parts. Although this construction method provides a solution for the installation of traditional offshore wind towers, the directional dismantling of abandoned traditional offshore wind towers remains a technical challenge. Utility Model Content

[0005] The purpose of the utility model is to provide a directional demolition limiting tool and a wind measurement tower containing the tool, which can drive the structure to be demolished to tilt in a directional manner under the traction of an external force, thereby achieving a rapid demolition effect.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] A directional dismantling limiting tool has a main body which is a fixed hinge support. The fixed hinge support is respectively provided with a locking component which can prevent relative rotation thereof and a traction seat for passing an external traction rope.

[0008] A wind measurement tower with a directional removal limit fixture, comprising a tower base platform, a tower, and a plurality of connecting flanges for connecting the tower base platform and the tower, wherein the connecting flanges include an upper flange fixed to a corner of the bottom end of the tower, a lower flange fixed to the tower base platform and corresponding to the upper flange, and connecting bolts connecting the upper flange and the lower flange. The tower also includes a plurality of the directional removal limit fixtures.

[0009] Among them, the upper end of the fixed hinge support of the directional dismantling limit tooling is fixed to the tower, and the lower end is fixed to the tower base platform. When all the connecting bolts are unscrewed from the upper flange and the lower flange, and the locking assembly is unlocked, the upper end of the fixed hinge support drives the tower to tilt directionally through external force.

[0010] Compared with the prior art, the advantages of the present invention are:

[0011] 1. The fixed hinge support cooperates with the locking assembly to prevent the fixed hinge support from rotating relative to the structure when the locking assembly is unlocked, thereby preventing the structure to be demolished from toppling due to external factors such as wind and misoperation, ensuring the safety and controllability of the directional demolition process.

[0012] 2. Through the cooperation of the traction seat and the swing arm, the external traction rope can accurately apply force, thereby effectively driving the structure to be demolished to fall, achieving the effect of rapid construction;

[0013] 3. By setting a limit assembly, the fixed hinge support is fixed after a certain angle of relative rotation, thereby preventing the excessive tipping of the demolished structure, thereby increasing the safety of the demolition process and facilitating the lifting and removal of the demolished structure;

[0014] 4. The directional dismantling limiter of this utility model can be used on a wind tower, making it a directional dismantling tower. When all connecting bolts are unscrewed from the upper and lower flanges and the locking assembly is released, an external traction rope is threaded through the towing seat, and the tower is pulled in a directional manner by external force.

DETAILED DESCRIPTION

[0026] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0027] like Figure 1-5 The figure shows an embodiment of a directional removal limiting tool provided by the present invention:

[0028] A directional dismantling limiting tool has a main body consisting of a fixed hinge support 1. The fixed hinge support 1 is provided with a locking assembly 2 for preventing relative rotation thereof and a traction seat 3 for passing an external traction rope.

[0029] The fixed hinge support 1 includes a hinge base 11 , a pin 12 and a swing arm 13 . One end of the swing arm 13 is connected to the hinge base 11 via the pin 12 , and the other end of the swing arm 13 can rotate relatively around the pin 12 .

[0030] The hinge base 11 includes two fixed legs 111 spaced apart from each other. The swing arm 13 is sandwiched between the two fixed legs 111 . Both the fixed legs 111 and the swing arm 13 are provided with openings for inserting the pin 12 .

[0031] The locking assembly 2 includes a first U-shaped lock buckle 21 and two first ear plates 22 respectively arranged on the left and right sides of the fixed hinge support 1. The first ear plate 22 is provided with a through hole extending forward and backward. The two legs of the first U-shaped lock buckle 21 pass through the two first ear plates 22 through the corresponding through holes, and the first locking nuts 23 are screwed on the parts of the two legs passing through the first ear plates 22.

[0032] A limiting component 4 for limiting excessive rotation of the fixed hinge support 1 is also provided below the locking component 2. The limiting component 4 includes a second U-shaped lock buckle 41 and two second ear plates 42 respectively arranged on the left and right sides of the fixed hinge support 1. The second ear plates 42 are provided with through holes extending forward and backward. The two legs of the second U-shaped lock buckle 41 pass through the two second ear plates 42 respectively through the corresponding through holes, and second locking nuts 43 are screwed on the parts of the two legs passing through the second ear plates 42.

[0033] The traction seat 3 is a circular ring, and the traction seat 3 is fixed to the top of the swing arm 13. Preferably, the circumference of the traction seat 3 is fixed to the top of the swing arm 13 by welding.

[0034] Connecting steel bars 5 for connecting to an external structure (such as a tower 602 of a wind tower) are provided on both the left and right sides of the swing arm 13. The connecting steel bars 5 can be welded to the external structure.

[0035] Preferably, the connecting steel bars 5 and the swing wall 13 are fixed by welding.

[0036] like Figure 6-10 The figure shows an embodiment of a wind tower provided by the present invention that includes a directional removal limit fixture:

[0037] A wind measurement tower including a directional removal limit fixture, comprising a tower base platform 601, a tower 602, and a plurality of connecting flanges 603 for connecting the tower base platform 601 and the tower 602. The connecting flanges 603 include an upper flange fixed to a corner of the bottom end of the tower 602, a lower flange fixed to the tower base platform 601 and corresponding to the upper flange, and connecting bolts connecting the upper and lower flanges. The tower also includes the aforementioned directional removal limit fixture.

[0038] Among them, the upper end of the fixed hinge support 1 with directional dismantling limit is fixed to the tower 602, and the lower end is fixed to the tower base platform 601. When all the connecting bolts are unscrewed from the upper flange and the lower flange, and the locking assembly 2 is unlocked, the upper end of the fixed hinge support 1 drives the tower 602 to tilt in a directional manner through external force.

[0039] like Figure 8As shown, the hinge base 11 of the fixed hinge support 1 is fixed to the tower base platform 601, and the swing arm 13 of the fixed hinge support 1 is fixed to the tower 602. When all connecting bolts are unscrewed from the upper and lower flanges and the locking assembly is unlocked, an external traction rope is passed through the traction base 3, and the tower is pulled by external force to tilt around the pin 12.

[0040] Furthermore, the hinge point of the fixed hinge support 1 should be located on the same horizontal line as the joint between the upper flange and the lower flange, so as to achieve a better traction effect.

[0041] There are two groups of directional removal limiting fixtures, which are located on the same side of the tower 602 and rotate in the same direction.

[0042] A wind tower with a directional dismantling limit fixture. The working principle and construction process of its directional dismantling are roughly as follows:

[0043] The main working principles of directional demolition are:

[0044] Through modeling and mechanical analysis, the key nodes for dismantling the tower 602 are found, and the above-mentioned directional dismantling limit fixtures are installed at the rigid connection points between the tower 602 and the tower foundation platform 601;

[0045] Subsequently, by releasing the original stress state of the rigid connection between the tower 602 and the tower base platform 601 (for example, removing the connecting bolts in the connecting flange 603), a weak stress point is formed at the directional demolition limit fixture. After releasing the lock of the locking assembly, the tower traction rope 7 pre-installed on the demolition key node and the traction seat traction rope 8 installed on the traction seat 3 are pulled by the winch of the construction ship, so that the tower 602 as a whole is tilted around the hinge axis of the directional demolition limit fixture, thereby realizing directional demolition.

[0046] The main construction process of directional demolition is:

[0047] S1. High-altitude special operations personnel climb onto the tower 602 to dismantle the recyclable wind measuring instruments and equipment on the tower 602, find the key section for dismantling, and install the tower traction rope 7.

[0048] S2. Install the above-mentioned directional removal limit fixture at the rigid connection point between the tower 602 and the tower base platform 601 (in some embodiments, in order to make the installation of the directional removal limit fixture fast and reliable, the part at the rigid connection point can be cut off, such as Figure 7 As shown, a portion of the connecting flange 603 is longitudinally cut away so that the directional removal limiting tool can fit as closely as possible with the tower 602 and the tower base platform 601).

[0049] S3. The construction worker puts the traction seat traction rope 8 on the traction seat 3.

[0050] S4. The construction workers use a steel wire rope to connect the installed tower traction rope 7 and traction seat traction rope 8, and fix them to the output end of the winch of the construction ship at a distance.

[0051] S5. The construction personnel release the original stress state of the rigid connection between the tower 602 and the tower foundation platform 601 (for example, remove the connecting bolts in the connecting flange 603), so that a stress weak point is formed at the directional removal limit tooling, and release the lock of the locking assembly.

[0052] S6. After all personnel have cleared the falling range of tower 602, the winch on the construction vessel is activated, causing tower 602 to tilt in a directional manner around the pin 12 of the directional removal limiter, pulled by the tower traction rope 7 and the traction base traction rope 8. The support base 11, pin 12, and swing arm 13 can then be separated from each other, completely separating tower 602 from the tower base platform 601.

[0053] S7. After the wind tower frame 602 is tilted down to the seabed, divers go into the water to conduct underwater exploration of the frame 602.

[0054] S8. If the divers find that the main structure of tower 602 is basically intact, two lifting wire ropes are passed underwater to the center point of tower 602 and connected to tower 602 with shackles. The construction vessel uses a crane at a 65° angle to lift the tower 602 of the wind measurement tower as a whole to the deck, and then cuts and disassembles it in sections.

[0055] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The present invention can also be applied to offshore fixed steel structures and building demolition, including but not limited to: wind measurement towers, wind turbines, lighthouses, oil drilling platforms, etc. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the scope of protection of the present invention.
