Description

Technical Field

[0001] This utility model belongs to the field of wind power mixed tower segment assembly technology, specifically relating to a self-leveling and self-identifying mixed tower segment assembly platform. Background Technology

[0002] Since onshore wind power projects entered the era of grid parity, there are currently three main technical means to improve the rate of return on investment and power generation: increasing turbine capacity, increasing rotor diameter, and increasing hub height. In the implementation of wind power projects, these three methods are usually used in combination to increase wind power generation. Larger turbines with taller towers have become the mainstream solution for increasing wind power generation in onshore wind power projects. To solve the resonance problem between the tall steel tower and the rotor, hybrid tower structures have emerged. Hybrid tower structures are assembled from hybrid tower segments. Traditional hybrid tower segment assembly platforms rely on manual operation for installation, and the quality of the assembly largely depends on the skill level of the assemblers, making it highly susceptible to human error. Furthermore, traditional hybrid tower segment assembly platforms are not specifically designed for the power supply and high-altitude operations of the assemblers, requiring them to carry power strips and ladders for the assembly work. When assembling a mixed tower using a traditional mixed tower segment assembly platform, A / C segments are placed on the platform first, structural adhesive is applied, and then B / D segments are placed in sequence. In this traditional splicing method, the structural adhesive on both sides of A / C segments is rubbed off during the descent of B / D segments, resulting in excessive accumulation of structural adhesive on the bottom sides of the segments and insufficient structural adhesive on the top sides of the segments, creating a risk point for leakage in the mixed tower.

[0003] With the advancement of digitalization, the construction process of hybrid tower segment hoisting has also undergone reforms. On digital wind power project sites, each hybrid tower segment has a QR code affixed to its surface, serving as its unique identification code. Digital construction has placed new demands on the hybrid tower segment splicing process, requiring the preservation of photos before and after splicing. These watermarked photos, as part of the hybrid tower's digital assets, facilitate quality traceability for later segment maintenance.

[0004] Therefore, the applicant proposes a self-leveling and self-identifying mixed tower segment assembly platform and a mixed tower segment assembly method. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a self-leveling and self-identifying mixed tower segment assembly platform. When all four segments are placed on the segment assembly platform, the gravity sensing module is activated, triggering the segment self-identification and uploading action, and checking for any deviations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-leveling and self-identifying mixed tower segment assembly platform includes a central platform, with several sets of segment assembly platforms arranged in a circular array around the central platform. Each set of segment assembly platforms is equipped with a self-leveling support leg at its bottom and a self-driven segment positioning device on each set of segment assembly platforms. A segment self-identification and uploading device is provided on the central platform.

[0008] Furthermore, the segment assembly platform includes a platform support beam, on which a pressure sensor is installed, and at each end of the bottom of the platform support beam is a self-leveling support leg.

[0009] Furthermore, the self-leveling outrigger includes a support rod, which is fixedly connected to the bottom of the platform support beam, and an electric hydraulic jack is installed under the support rod.

[0010] Furthermore, the platform support beams consist of eight beams, the central platform is octagonal or circular, and the eight platform support beams are evenly distributed in a star-shaped pattern on the edge of the central platform and are detachably connected by a connecting structure.

[0011] Furthermore, the connection structure includes a slot on the central platform and a block at one end of the platform support beam, with the block engaging with the slot.

[0012] Furthermore, each of the platform support beams is equipped with a levelness intelligent recognition device. The levelness intelligent recognition device includes a cavity, on one side of the outer wall of the cavity a first camera and a laser emitter are provided, and on the other side of the outer wall of the cavity a scale is provided, with the adjacent first camera and laser emitter corresponding to the scale.

[0013] Furthermore, it also includes an elevator, which is placed inside the cavity when folded up.

[0014] Furthermore, the self-driven segment positioning device includes a crank-rocker reciprocating mechanism, a push plate is provided at the front of the crank-rocker reciprocating mechanism, a rubber pad is provided on the push plate, a positioning hole is provided on the base of the crank-rocker reciprocating mechanism, and a long row of holes is provided on the platform support beam.

[0015] Furthermore, the segment self-identification and uploading device includes a second camera and a laser rangefinder. A pole with a height of 2-4 meters is set on the central platform, and the second camera and laser rangefinder are rotatably mounted on the top of the pole.

[0016] The advantages of this utility model of a self-leveling and self-identifying mixed tower segment assembly platform are:

[0017] 1. The assembly platform is equipped with scales, which, combined with a laser rangefinder, can quantify the specific descent height of the self-leveling outriggers;

[0018] Second, the assembly platform is equipped with a self-driven segment positioning device for the upper and lower segments, which can adjust the displacement of the upper and lower ends of the segments. Combined with a laser rangefinder, the displacement of the segments can be adjusted more accurately.

[0019] Third, the assembly platform integrates power supply and access platform, which can provide convenience for the power supply and access engineering faced by mixed tower crane construction.

[0020] Fourth, by using the laser emitter on the platform support beam, the tunnel segment can be placed on the platform and leveled relatively quickly and accurately. Attached Figure Description

[0028] The present invention will be described in detail below with reference to specific implementation examples. The following implementation examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way.

[0029] like Figure 1 — Figure 7As shown, this utility model relates to a self-leveling and self-identifying mixed tower segment assembly platform, including a central platform 1. Several sets of segment assembly platforms 2 are slidably arranged in a circular array with the center point A of the central platform 1 as the center. Each set of segment assembly platforms 2 has a self-leveling support leg 3 at its bottom and a self-driven segment positioning device 4 on each set of segment assembly platforms 2. A segment self-identification and uploading device 5 is installed on the central platform 2. The segment assembly platform 2 includes a platform support beam 6, with a pressure sensor 61 installed on the platform support beam 6. A self-leveling support leg 3 is installed at each end of the bottom of the platform support beam 6. Each self-leveling support leg 3 includes a support rod 31, which is fixedly connected to the bottom of the platform support beam 6. An electric hydraulic jack 32 is installed below the support rod 31. The platform support beams 6 consist of eight beams. The central platform 1 is octagonal or circular. The eight platform support beams 6 are evenly distributed in a star-shaped pattern on the edge of the central platform 1 and are slidably connected by a sliding connection structure. The sliding connection structure includes a sliding groove 11 on the central platform 1 and a sliding block 12 at one end of each platform support beam 6. The sliding block 12 cooperates with the sliding groove 11. A levelness intelligent recognition device 7 is installed on each platform support beam 6. The levelness intelligent recognition device 7 includes a cavity 70, on which a first camera 71 and a laser emitter 72 are installed. A scale 73 is provided on one outer wall of the cavity 70. The scale 73 can be transferred, decal, or engraved. The scale corresponding to the laser emitter 72 is the elevation of the support beam 6 of the tunnel segment platform. The distance the self-leveling outriggers 3 rise or fall can be quantified and adjusted using specific data. The adjustment is performed by the electro-hydraulic jack 32, which drives the support rod 31 to rise or fall, thus adjusting the height of the platform support beam 6 and bringing all eight self-leveling outriggers 3 to the same height. The elevation adjustment algorithm is as follows: First, obtain the elevation data corresponding to the eight self-leveling outriggers 3. Calculate the average value of the corresponding elevation data and find the data with the most values ​​whose absolute value is within 2mm of the average value. This data is used as the standard value for the current elevation adjustment, and the eight self-leveling outriggers 3 will automatically adjust to the position corresponding to this elevation. The working principle of the electro-hydraulic jack is that the hydraulic cylinder drives the support rod 31 to achieve lifting. After power is cut off, the hydraulic fluid will not flow back, ensuring that the heavy object will not fall on its own.

[0030] Furthermore, it also includes a lifting platform 74. When collapsed, the lifting platform 74 is placed in the cavity 70. The lifting platform can facilitate the assembly workers in unhooking and applying torque, and make it easy for the assembly workers to go up and down the assembly platform. Power outlets can also be installed on each platform support beam 6 to meet the power needs during the assembly of the mixed tower segments (e.g., the use of electric wrenches and welding machines).

[0031] Furthermore, the self-driven segment positioning device 4 includes a crank-rocker reciprocating mechanism 40, a push plate 41 is provided at the front of the crank-rocker reciprocating mechanism 40, a rubber pad 42 is provided on the push plate 41, a positioning hole 44 is provided on the base 43 of the crank-rocker reciprocating mechanism 40, and a long row of holes 45 is provided on the platform support beam 6. The positioning hole 44 is fixed to any one of the holes 45 by screws.

[0032] The crank-rocker reciprocating mechanism 40 is existing technology, and its specific structure is well-known and will not be described in detail here. In actual production, other reciprocating mechanisms such as connecting rod-cam mechanisms can also be used, which are equivalent replacements. The pusher plate 41 is arc-shaped, which can better fit the outer wall of the tube and leave no pushing marks on the outer surface of the tube.

[0033] The push plate 41 is also provided with a detachable connecting sleeve 46, which is connected to the connecting rod at the front of the crank-rocker reciprocating mechanism 40. The long row of holes allows the installation position of the reciprocating mechanism to be adjusted according to the size and offset of the tube segments, thereby adjusting the propulsion distance.

[0034] Furthermore, the segment self-identification and uploading device 5 includes a second camera 51 and a rotatable laser rangefinder 52. A pole 53 with a height of 2-4 meters is set on the central platform 1, and the second camera 51 and laser rangefinder 52 are rotatably mounted on the top of the pole 53. The distances from the ends and center of the four mixed-tower segments to the center of the circle can be measured separately, thereby obtaining the distance the mixed-tower segments should move towards the center. This ensures that the four mixed-tower segments can reach a mating state at the same time, rather than being positioned one after the other, which could cause structural adhesive to be scraped and lost. The segment identification and uploading device 5 calculates and analyzes the moving speed of the four mixed-tower segments based on the arrival time and distance, and feeds this information back to the self-driven segment positioning device 4.

[0035] In this scheme, when the assembly workers place all four hybrid tower segments on the platform support beam 6, the pressure sensor 61 on the platform support beam 6 is activated, triggering the segment self-identification and uploading device 5. This device automatically identifies the QR code on the hybrid tower segment and takes and uploads a photo of the segment's interior before assembly. By comparing the quantity and position of the embedded parts in the hybrid tower segments with the design drawings, it checks for any deviations and simultaneously checks whether the hybrid tower segments A to D are assembled clockwise / counterclockwise. After confirming that the above checks are correct, structural adhesive is applied, and the self-driven segment positioning device 4 completes the positioning of the hybrid tower segments. It is worth noting that the hybrid tower segments arrive at their corresponding positions simultaneously at different speeds, effectively ensuring the structural adhesive on both sides of the segments is compacted, preventing any missing adhesive. The levelness intelligent identification device 7 then feeds back the obtained levelness deviation data to the control center. The self-leveling algorithm controls the self-leveling support legs 3 to automatically adjust their height, obtaining the optimal support leg adjustment scheme, thus achieving the self-leveling function. After the assembly of the mixed-tower segments is completed, the second camera 51 and laser rangefinder 52 on the segment self-identification and uploading device 5 perform 360° panoramic shooting to check the levelness of the top of the mixed-tower segments and mark any parts that do not meet the technical requirements with laser irradiation. This invention can realize the functions of self-positioning, self-leveling, and self-inspection of mixed-tower segments, reducing the workload of assembly workers and converting some manually controlled quality processes into mechanical control. The special positioning device avoids the phenomenon of the upper structural adhesive being scraped to the lower part and accumulating in the traditional mixed-tower segment positioning. At the same time, this platform is equipped with a lifting ladder 74, which can facilitate the assembly workers to unhook and apply torque.

[0036] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
