Description

Technical Field

[0001] This invention relates to the field of storage and transportation technology for wind power concrete tower construction segments, and particularly to an assembled storage device and construction method for wind power concrete tower construction segments. Background Technology

[0002] Onshore concrete tower wind turbine structures have become one of the main forms of wind power project construction. Wind power projects are often located in flat farmland areas, and coordinating construction land has always been a major challenge. Traditional methods for storing wind turbine concrete tower segments are divided into two types: one is to use transport vehicles as temporary storage equipment, which is time-consuming, costly, and consumes transportation resources; the other is to temporarily place horizontal timber pads on open ground to store the segments, which poses a high safety hazard and is also limited by site conditions, weather, and other factors, requiring high precision in site conditions.

[0003] Taking a concrete tower wind power project as an example, a single tower needs to be composed of 184 ring segments. The manufacturer of the single ring segments is 110km away from the wind power tower construction site. Considering factors such as transportation, site coordination, construction period, and cost, it is urgent to develop a reasonable temporary storage equipment and method for the segments at the wind power tower construction site.

[0004] How to solve the above problems is the research topic of this plan. Summary of the Invention

[0005] To achieve the above-mentioned objectives and address the aforementioned technical problems, this invention provides a prefabricated storage device and construction method for wind power concrete tower construction segments, thereby solving the problems mentioned in the background art, such as the excessively high cost of storing heavy segments during the construction of concrete tower wind power projects and the damage to the construction site caused by inappropriate segment storage methods. This ensures efficient on-site storage and use of wind power concrete segments in soft foundation environments.

[0006] The technical solution includes several evenly distributed electromagnetic roadbed boxes, an assembled guide rail set on the top of the electromagnetic roadbed boxes, baffle support mechanisms set at both ends of the assembled guide rail, several interconnected segment storage units set on the top of the assembled guide rail, a power supply device, and a winch. The segment storage unit includes a segment placement slot for placing segments, a pulley mechanism symmetrically arranged at the bottom of the segment placement slot, and the bottom surface of the segment placement slot is made of a strong magnet. The segment placement slot is slidably connected to the assembled guide rail via a pulley mechanism; An electromagnetic conversion device is installed inside the electromagnetic roadbed box. The assembled guide rail is connected to the electromagnetic roadbed box by magnetic attraction; the baffle support mechanism is connected to the electromagnetic roadbed box by magnetic attraction. The power supply unit includes a diesel generator and a switch, with the diesel generator supplying power to the electromagnetic conversion device.

[0007] The electromagnetic roadbed box uses a roadbed box as the main structure, and the electromagnetic conversion device is installed in the hollow structure of the roadbed box; The switch is installed on one side of the electromagnetic roadbed box, and the electromagnetic conversion device, the switch, and the diesel generator are electrically connected.

[0008] The pulley mechanism includes two upright plates, a fixed shaft disposed between the two upright plates, and a pulley rotatably connected to the middle of the fixed shaft; The tops of the two upright plates are fixedly connected to the bottom of the segment placement groove. The tops of the two upright plates are welded to the bottom of the segment placement groove.

[0009] The upper surface of the assembled guide rail is provided with a limiting groove that matches the vertical plate, and the bottom of the vertical plate is slidably connected to the limiting groove.

[0010] Adjacent segment placement slots are fixedly connected by a rope fixing mechanism, and the end segment placement slots are connected to the winch by a traction rope.

[0011] The baffle support mechanism includes two strip baffles, which are disposed at both ends of the assembled guide rail and are magnetically connected to the electromagnetic roadbed box.

[0012] The rope fixing mechanism includes a connecting seat, a fixing rod, and a rope; A connecting seat is provided on the side wall of the segment placement slot, and a fixing rod is fixedly installed on the connecting seat. The fixing rods on the two segment placement slots are fixedly connected by ropes. The traction rope is also connected to the segment placement slot via a connecting seat and a fixing rod.

[0013] The bottom of the assembled guide rail and baffle support mechanism is made of ferromagnetic material. When current passes through the electromagnetic conversion device, a strong magnetic field is generated on the surface of the electromagnetic roadbed box, which attracts the ferromagnetic material at the bottom of the assembled guide rail and baffle support mechanism, thus achieving firm adsorption.

[0014] This solution provides a heavy-duty tunnel segment support and stabilization platform and transportation route that can be quickly assembled on-site, ensuring the storage of heavy-duty tunnel segments on soft foundations and improving the turnover efficiency of heavy-duty tunnel segments.

[0015] The construction method based on the prefabricated storage device for tunnel segments in wind power concrete tower construction includes the following steps: S1. Customize the electromagnetic roadbed box. Plan the layout of the prefabricated guide rails on the surface of the electromagnetic roadbed box according to the segment size. The distance between the two ends of the prefabricated guide rails is greater than 2 / 3 of the transverse width of the segment. Fix the electromagnetic conversion device in the hollow area of ​​the electromagnetic roadbed box. S2. Based on the on-site construction conditions, determine the location and route of the electromagnetic roadbed boxes, and install prefabricated guide rails on the electromagnetic roadbed boxes. S3. Install baffle support mechanisms on both sides of the prefabricated guide rail, and arrange segment storage units above the prefabricated guide rail and baffle support mechanisms. S4. After the entire segment storage and transportation device is installed on the construction site, when the segment storage begins, the electromagnetic conversion device is activated according to the number of segments. The assembled guide rail, baffle support mechanism and electromagnetic roadbed box are connected by magnetic attraction; providing support and limiting for several segment storage units.

[0016] S5. Securely connect the segment placement slots with ropes, connect the end segment placement slots to the winch with traction ropes, shut down the individual electromagnetic conversion device, and remove the baffle support mechanism under the segment to be transferred.

[0017] S6. Start the winch and transfer the tunnel segments to the hoisting construction area.

[0018] S7. After completing the segment transfer, transport the segment storage unit to the starting point to prepare for the next segment transfer and storage. Repeating steps S2 to S3 can enable regional heavy tunnel segment storage under soft foundation conditions, and repeating steps S5 to S7 can enable regional heavy tunnel segment transfer under soft foundation conditions, thereby ensuring the safety of on-site construction personnel and improving the efficiency of heavy tunnel segment turnover and transportation.

[0019] An electromagnetic roadbed box generally refers to a roadbed box as the main structure, with an electromagnetic conversion device installed in the hollow structure of the roadbed box. The device is connected to a switch and a diesel generator on the electromagnetic roadbed box via a network of cables. Prefabricated guide rails are laid on the surface of the electromagnetic roadbed box according to the size and quantity of the tunnel segments. Tunnel segment placement slots are arranged on the prefabricated guide rails. A baffle support mechanism is installed around the pulley mechanism and contacts the tunnel segment placement slots and the surface of the roadbed box. The tunnel segment placement slots are customized according to the size of the tunnel segments. The width of the tunnel segments should be slightly smaller than the width of the tunnel segments, and the width of the tunnel segments should be greater than the thickness of the tunnel segments plus the offset of the arc.

[0020] During routine storage of tunnel segments, the power generation state is maintained, thereby ensuring the fixation of the assembled guide rail and baffle support mechanism 5. The baffle support mechanism can effectively alleviate the deformation of the pulley mechanism, while fixing the tunnel segment placement slot and the pulley mechanism to the electromagnetic roadbed box.

[0021] When in motion, the current switch of the roadbed box is turned off. Each roadbed box can be operated independently. The winch pulley mechanism is used to move the box forward to the hoisting construction position. After the hoisting is completed, the segment placement slot is manually reset.

[0022] The thickness of the electromagnetic roadbed box should be 20cm, and its surface area should be greater than the total area used by the multi-ring segments and their supporting structures. Customized electromagnetic roadbed boxes can be deployed on-site after the path is simply marked on the surface of a general-purpose roadbed box. Their overall size should not be too large, and they can store four ring segments. Their main function is to store and transfer segments.

[0023] The segment placement slots are laid out according to the marked path using magnetic connections. Precise positioning is required during the laying process to ensure that the segments are accurately placed into the storage structure during hoisting operations.

[0024] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows: This solution provides a prefabricated storage device and construction method for wind power concrete tower construction segments, which overcomes many problems such as high implementation cost, complex process and low safety of storing heavy segments on soft foundations. It can effectively and standardly utilize the land area of ​​the wind power concrete tower construction site, while efficiently ensuring the safety of heavy segments on the construction site. By quickly deploying the modified roadbed boxes, a segment storage plane is formed in the harsh construction site. Then, by setting positioning and anti-overturning limiting structures on the roadbed boxes, an efficient and safe segment storage site is formed. It avoids the waste of resources and environmental damage caused by temporary construction measures such as site reinforcement on weak foundation working surfaces, and also greatly reduces the danger for construction workers to carry out daily construction work on construction sites with many tunnel segments, and greatly improves the efficiency of tunnel segment hoisting and transportation. This technology addresses the core issue of the lack of safe, fast, and low-cost temporary storage equipment for heavy tunnel segments in concrete tower wind power projects with soft foundations. It effectively reinforces the soft foundation while ensuring the safe and stable storage of heavy tunnel segments, representing an innovative breakthrough in low-cost temporary storage methods for heavy tunnel segments on soft foundations. This technology can guarantee the safe storage of a large number of heavy tunnel segments on soft foundations, thereby significantly reducing construction costs for concrete tower wind power projects. It also provides the necessary foundation for shortening project duration and ensuring construction safety, and improves the construction efficiency of concrete towers in wind power projects.

[0025] Furthermore, the device involved in this patent has a simple structure, is easy to manufacture, easy to assemble and disassemble, has good reusability, can be recycled multiple times, and effectively improves economic benefits. Attached Figure Description
