Description

Technical Field

[0001] This invention relates to the field of steel tower segment connection technology, and in particular to an autonomous correction control steel tower segment assembly device and assembly method. Background Technology

[0002] As a tall structure, steel towers require excellent stability and load-bearing capacity. During the construction of a steel tower, the dimensions and position of each steel pipe segment must be precisely controlled to ensure the accuracy and stability of the entire tower structure. However, due to various factors (such as manufacturing errors and transportation vibrations), there may be some deviation in the position of the steel pipe segments during connection. Therefore, steel tower segment connection correction is necessary to adjust and correct these deviations.

[0003] The existing large-scale high-altitude steel tower docking requires a significant manpower investment and a certain level of technical expertise and experience. In more complex usage and construction environments, such as high altitudes and severe weather conditions, even more manpower may be needed to meet the challenges. If the project schedule is tight, it is necessary to increase manpower to ensure that the project is completed on time.

[0004] This invention proposes an assembly device and method for autonomously correcting and controlling steel tower segments. Summary of the Invention

[0005] Based on the existing technical problems of steel tower segment connection, this invention proposes an autonomous correction and control steel tower segment assembly device and assembly method.

[0006] This invention proposes an assembly device and method for an autonomously corrective control steel tower segment, comprising a steel tower. A correction mechanism is fixedly connected to each of the four sides of the upper end of the steel tower. Each correction mechanism includes a support block fixed to the side of the steel tower. A first hydraulic rod is fixedly connected to the upper surface of the support block. A hydraulic pipe is connected to the lower side of the first hydraulic rod, and one end of the hydraulic pipe is fixedly connected to a hydraulic oil tank. A second hydraulic rod is rotatably connected to the upper end of the first hydraulic rod. Fixing blocks are respectively provided on both sides of the outer side of the second hydraulic rod. A fixing rod fixed to the outer side of the second hydraulic rod is fixedly connected to the inner ring of a bearing embedded inside the fixing block. A support plate is fixedly connected to the ground of the two fixing blocks. A support frame is fixedly connected to the lower surface of the support plate. One side of the support frame is fixedly connected to the side of the steel tower. A correction block is rotatably connected to the upper end of the second hydraulic rod. A sensor is embedded in one side of the correction block. A steel tower segment is suspended directly above the correction mechanism. A crane is fixedly connected to the upper end of the steel tower segment. An oil inlet device is electrically connected to the vertical surface of the steel tower of the crane.

[0007] The oil inlet device includes a lift, with fixed rings fixedly connected in an array along the vertical direction on the surface of the lift. A connecting pipe is fixedly connected to the inner wall of the fixed ring, and an oil inlet pipe is fixedly connected to the upper end of the connecting pipe. The inner wall of the oil inlet pipe is fixedly connected to the inner wall of the hydraulic oil tank. A controller is fixedly connected to the other side of the lift.

[0008] Preferably, the plurality of connecting pipes are fixedly connected by flanges.

[0009] Preferably, a support rod is fixedly connected to the lower surface of the hydraulic oil tank, and the support rod is respectively connected to the inner side of the two steel towers.

[0010] Preferably, the central axis of the second hydraulic rod is parallel to the side of the steel tower, and alumina abrasive is sprayed on one side of the correction block.

[0011] Preferably, the support frame is triangular in shape and made of Q345 steel.

[0012] Preferably, each of the fixed blocks is provided with a light sensor on the side closest to the steel tower segment.

[0013] Preferably, the elevator drives the oil inlet pipe to rise and fall.

[0014] Preferably, in step one, the crane lifts the steel tower segment to the position directly above the installation location of the steel tower, and then slowly lowers the steel tower segment until the lower end surface of the steel tower segment contacts the side of the correction block and stops. Step 2: The sensor fixed to the side of the correction block transmits the electrical signal to the controller. The controller receives the data, processes it, and generates a control signal that is transmitted to the hydraulic system. The controller controls the oil to enter the connecting pipe and inject hydraulic oil into the hydraulic tank. At the same time, the controller controls the first and second hydraulic rods to start working. The first hydraulic rod extends upward, driving one end of the second hydraulic rod to rise. Simultaneously, under the action of the first hydraulic rod, the correction block at the other end of the second hydraulic rod descends until the side of the correction block is completely in contact with the side of the steel tower segment. Step 3: The controller pre-sets the extension and retraction length of the second hydraulic rods on the four sides. The controller controls the first hydraulic rod and the second hydraulic rod to make fine adjustments until the extension and retraction length of the second hydraulic rods on the four sides of the steel tower is equal to the preset length of the second hydraulic rod. At this time, the side of the correction block is in contact with the side of the steel tower segment, and the controller terminates the control of the second hydraulic rod. Step 4: The crane slowly lowers the hoisted steel tower segment until it connects with the steel tower below. After the connection is completed, each first and second hydraulic rod returns to its initial state under the control of the controller, and the correction block moves away from the connected steel tower segment.

[0015] Preferably, the controller has a built-in control system, which includes a data management module, a docking calculation module, an actuator module, and a report generation module. The data management module is used to receive and process sensor data. The docking calculation module is used to calculate control signals from the processed data; The actuator module controls the hydraulic system to perform actions via control signals received from the hydraulic system, thereby driving the steel tower segments to connect. The report generation module generates correction report data based on each push of the steel tower segment.

[0016] The beneficial effects of this invention are as follows: 1. By setting up a correction mechanism, when the lower end of the steel tower segment is lowered to fit against the correction block, pressure is applied to the sensor embedded inside the correction block. With the assistance of the oil inlet device, the correction mechanism makes slight adjustments to the lowered steel tower segment in the horizontal direction, ensuring that the lower end of the steel tower segment is fully connected to the upper end of the steel tower after lowering. This mechanism can monitor and autonomously correct the internal force and attitude of the steel tower segment in real time, improving assembly accuracy. It has strong adaptability and scalability and can be applied to steel tower projects of different types and scales. Moreover, by adopting advanced control system and sensor technology, it achieves efficient assembly, especially reducing manpower input, lowering the difficulty and cost of manual operation, and improving construction efficiency.

[0017] 2. By setting up an oil inlet device, multiple oil inlet pipes connected by flanges can transport hydraulic oil from the ground to the hydraulic oil tank between steel towers at a specified height under the drive of the elevator, ensuring that the hydraulic oil volume of the entire hydraulic system is sufficient during use, and the entire oil inlet device can be disassembled immediately for easy installation.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figures 1-5 An assembly device and method for an autonomously correcting and controlling steel tower segment includes a steel tower 1. A correction mechanism 2 is fixedly connected to each of the four sides of the upper end of the steel tower 1. The correction mechanism 2 includes a support block 21 fixed to the side of the steel tower 1. A first hydraulic rod 22 is fixedly connected to the upper surface of the support block 21. A hydraulic pipe 23 is connected to the lower side of the first hydraulic rod 22. One end of the hydraulic pipe 23 is fixedly connected to a hydraulic oil tank 24. A second hydraulic rod 25 is rotatably connected to the upper end of the first hydraulic rod 22. Fixing blocks 26 are respectively provided on both sides of the outer side of the second hydraulic rod 25. The rod 25 is fixed to the fixed rod on its outer side and the bearing inner ring embedded in the fixed block 26. The two fixed blocks 26 are fixedly connected to the ground with a support plate 27. The lower surface of the support plate 27 is fixedly connected to a support frame 28. One side of the support frame 28 is fixedly connected to the side of the steel tower 1. The upper end of the second hydraulic rod 25 is rotatably connected to a correction block 29. A sensor is embedded in one side of the correction block 29. The steel tower segment 3 is suspended directly above the correction mechanism 2. The upper end of the steel tower segment 3 is fixedly connected to a crane 4. The surface of the vertical steel tower of the crane 4 is electrically connected to an oil inlet device 5.

[0022] The oil inlet device 5 includes a lift 51. A fixed ring 52 is fixedly connected in an array along the vertical direction of the surface of the lift 51. A connecting pipe 53 is fixedly connected to the inner wall of the fixed ring 52. An oil inlet pipe 54 is fixedly connected to the upper end of the connecting pipe 53. The inner wall of the oil inlet pipe 54 is fixedly connected to the inner wall of the hydraulic oil tank 24. A controller 6 is fixedly connected to the other side of the lift 51.

[0023] In this embodiment, multiple connecting pipes 53 are fixedly connected by flanges. Specifically, the above-mentioned structural design can raise multiple connecting pipes 53 to the height required to connect to the steel tower segment 3 under the drive of the elevator 51, and fix them to the hydraulic oil tank 24 through the oil inlet pipe 54 to ensure that the hydraulic oil volume of the entire hydraulic system is sufficient during use. The entire oil inlet device 5 can be disassembled immediately for easy installation.

[0024] In this embodiment, a support rod is fixedly connected to the lower surface of the hydraulic oil tank 24, and the support rod is connected to the inner side of the two steel towers 1 respectively. Specifically, the structural design of the support rod ensures the stability of the steel tower 1 at high altitudes to a certain extent and also provides support for the hydraulic oil tank 24, ensuring the normal operation of the entire hydraulic system.

[0025] In this embodiment, the central axis of the second hydraulic rod 25 is parallel to the side of the steel tower 1, and one side of the correction block 29 is sprayed with alumina abrasive. Specifically, in the above structural design, when the steel tower segment 3 is lowered and contacts one side of the correction block 29, one side of the correction block 29 fits against the side of the steel tower segment 3. The length of the second hydraulic rod 25 shortens simultaneously with the rise of the first hydraulic rod 22 until it is parallel to the horizontal plane. The second hydraulic rod 25 applies thrust to the steel tower segment 3 for hydraulic fine-tuning. The alumina abrasive sprayed on the surface of the correction block 29 has high hardness, strong wear resistance, and high chemical stability. When the second hydraulic rod 25 applies pressure to the steel tower segment 3, the alumina abrasive increases the friction between the correction block 29 and the steel tower segment 3, while avoiding direct friction between the two, which would damage the surface of the steel tower segment 3.

[0026] In this embodiment, the support frame 28 is arranged in a triangle and is made of Q345 steel; Specifically, the triangular design of the support frame 28 increases its stability and provides sufficient support for the entire hydraulic system to a certain extent, enabling the hydraulic system to operate stably. The use of Q345 steel enhances the rigidity of the support frame 28, thereby improving its performance.

[0027] In this embodiment, each fixing block 26 is equipped with a light sensor on the side closest to the steel tower segment 3. Specifically, the light sensor can detect in real time whether the distance between the lower surface of the steel tower segment 3 lowered by the crane 4 and the side of the light sensor installed on the fixing block 26 is the same as the preset distance, so that the controller 6 can determine whether the lower end of the steel tower segment 3 is aligned with the upper end of the steel tower 1.

[0028] In this embodiment, the elevator 51 drives the oil inlet pipe 54 to rise and fall; specifically, with the above structural design, under the drive of the elevator 51, multiple oil inlet pipes 54 can transport hydraulic oil from the ground to the hydraulic oil tank 24 between the steel towers 1 at a specified height through the connection of flanges, ensuring that the hydraulic oil volume of the entire hydraulic system is sufficient during use.

[0029] In this embodiment, the specific steps are as follows: Step 1: The crane 4 lifts the steel tower segment 3 to the position directly above the installation location of the steel tower 1, and the crane 4 slowly lowers the steel tower segment 3 until the lower end surface of the steel tower segment 3 contacts the side of the correction block 29 and stops. Step 2: The sensor fixed to the side of the correction block 29 transmits an electrical signal to the controller 6. The controller 6 receives the data, processes it, and generates a control signal that is transmitted to the hydraulic system. The controller 6 controls the oil to enter the connecting pipe 53, injecting hydraulic oil into the hydraulic oil tank 24. At the same time, the controller 6 controls the first hydraulic rod 22 and the second hydraulic rod 25 to start working. The first hydraulic rod 22 extends upward, driving one end of the second hydraulic rod 25 to rise. Simultaneously, under the action of the first hydraulic rod 22, the correction block 29 at the other end of the second hydraulic rod 25 descends until the side of the correction block 29 is completely in contact with the side of the steel tower segment 3. Step 3: The controller 6 pre-sets the extension and retraction length of the second hydraulic rods 25 on the four sides. The controller 6 controls the first hydraulic rod 22 and the second hydraulic rod 25 to make fine adjustments until the extension and retraction length of the second hydraulic rods 25 on the four sides of the steel tower 1 is equal to the preset length of the second hydraulic rods 25. At this time, the side of the correction block 29 is in contact with the side of the steel tower segment 3, and the controller 6 terminates the control of the second hydraulic rods 25. Step 4: The crane 4 slowly lowers the hoisted steel tower segment 3 until it connects with the steel tower 1 below. After the connection is completed, each first hydraulic rod 22 and second hydraulic rod 25 returns to its initial state under the control of the controller 6, and the correction block 29 moves away from the steel tower segment 3 that has been connected.

[0030] In this embodiment, the controller 6 has a built-in control system, which includes a data management module, a docking calculation module, an actuator module, and a report generation module. The data management module is used to receive and process sensor data. The docking calculation module is used to calculate control signals from the processed data; The actuator module controls the hydraulic system to execute actions via control signals received from the hydraulic system, thereby driving the steel tower segment 3 to connect. The report generation module generates correction report data based on each push of the steel tower segment 3.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
