Description

Technical Field

[0001] The present invention relates to the technical field of bridge reinforcement, and in particular to a large-span assembled I-beam lifting system and a beam lifting method in strong typhoon sea areas. Background Art

[0002] Bridge construction in typhoon-prone seas, especially the hoisting operations of large-span prefabricated I-beams, faces many challenges. Traditional hoisting methods are often difficult to adapt to the complex and changeable marine environment, especially during the typhoon season, when strong winds, huge waves and high salt spray environments place higher demands on the safety and efficiency of hoisting operations.

[0003] The existing automatic docking technology between I-beam and gantry generally completes the docking between the gantry lifting components and the I-beam through the cooperation between the gantry and the operator. However, during the docking, if unexpected situations occur, such as gantry shaking, I-beam position displacement, etc., the operator may face safety risks such as being hit and squeezed. Especially in complex environments such as strong typhoon seas, the safety risks will be further increased due to the interference of the natural environment.

[0004] Moreover, as modern engineering construction places increasingly higher demands on efficiency and precision, the existing manually assisted docking methods have obvious deficiencies in terms of automated data collection and automatic adjustment of docking positions. They are difficult to effectively integrate with other advanced automated construction equipment and systems, which is not conducive to the intelligent development of the entire engineering construction.

[0005] In view of the above problems, the present invention proposes a large-span assembled I-beam lifting system and a beam lifting method for strong typhoon sea areas. Summary of the invention

[0012] Preferably, the width of the U-shaped frame opening is greater than the thickness of the upper end of the I-beam.

[0013] Preferably, the fixing mechanism includes a hydraulic cylinder 1 arranged between the two electric telescopic rods, the lower end of the hydraulic cylinder 1 is fixedly connected to a hydraulic motor, the rotating part of the hydraulic motor is fixedly connected to a nut, the inner wall of the fixed groove is provided with a hydraulic cylinder 2, one end of the hydraulic cylinder 2 is fixedly connected to a slip ring, the lower end of the slip ring is fixedly connected to a hook, the inner wall of the slide groove opened on the lower surface of the fixed plate is fixedly connected to a slide rod, and the inner ring surface of the slip ring is slidably connected to the surface of the slide rod.

[0014] Preferably, the lower end of the hook is cylindrical, and the cylindrical surface is provided with threads, and the lower end of the hook is matched with the lower end of the nut.

[0015] Preferably, the hanging ring provided at the upper end of the I-beam is located between the two nuts.

[0016] Preferably, the diameter of one end of the nut is smaller than the diameter of the hanging ring provided at the upper end of the I-beam, and the diameter of the other end of the nut is larger than the diameter of the hanging ring provided at the upper end of the I-beam.

[0017] Preferably, the industrial camera is built-in with an image sensor module, an optical lens module, an image processing module, an angle calculation module, a communication module, a storage module and a control module. The image sensor module is responsible for converting the optical image into an electrical signal or a digital signal. The optical lens module is used to focus light and accurately project the image of the hanging ring onto the image sensor. The image processing module is responsible for processing the image acquired by the image sensor. The angle calculation module calculates the deflection angle of the hanging ring according to the hanging ring features extracted by the image processing module. The communication module is used to transmit and communicate data with external devices. The storage module is used to save images and related data taken by the camera. The control module is mainly used to coordinate the work of various modules inside the camera.

[0018] Preferably, the beam lifting method of the large-span assembled I-beam lifting system in strong typhoon sea areas has the following operating steps:

[0019] Step 1: Move the I-beam to one side of the bridge by using a mobile device. After it is placed securely, the lifting component of the gantry drives the fixed component to move to the top of the I-beam, and then the lifting component drives the fixed component to descend. Under the real-time monitoring of the industrial camera, the fixed component descends to the specified height and the lifting component stops working;

[0020] Step 2: The output shaft of the motor drives the bevel gear 1 and bevel gear 2 to rotate, and then drives the connection block fixed to the rotating column to rotate. The electric telescopic rod rotates 70 degrees under the action of the connection block, and the motor continues to rotate to cooperate with the electric telescopic rod to drive the U-shaped frame close to the I-beam until the opening of the U-shaped frame fits with the upper end of the I-beam. The motor stops working and the electric telescopic rod begins to shrink until the Mack wheel fits tightly with the upper end surface of the I-beam. Then the electric telescopic rod rotates 20 degrees again. At this time, the industrial camera detects whether the position of the hanging ring at the upper end of the I-beam is within the preset position range.

[0021] Step 3: If the position of the hanging ring is not within the preset range, the Mack wheel is used to move horizontally until the hanging ring is adjusted to the preset position of the industrial camera. If the angle of the hanging ring is not within the preset range, the industrial camera sends abnormal information to the client through the communication module.

[0022] Step 4. After the hanging ring is determined by the industrial camera to be within the preset range, the lifting component of the gantry continues to descend until the lower end of the limit cover contacts the upper surface of the I-beam, and the lifting component stops descending. Hydraulic cylinder 1 drives the nut fixedly connected to the rotating component of the hydraulic motor to descend to a position level with the hanging ring. Hydraulic cylinder 2 drives the slip ring to move on the slide rod, and the lower end of the hook moves through the hanging ring. After the lower end of the hook enters the nut, the hydraulic motor drives the nut to rotate, and hydraulic cylinder 2 continues to move until the hydraulic motor stops after rotating two circles. At this time, the end with a larger diameter of the nut is tightly fitted with the surface of the hanging ring. After the docking is completed, the industrial camera sends a signal to the lifting component of the gantry to start lifting.

[0023] The beneficial effects of the present invention are:

[0024] 1. By setting up the positioning mechanism, the lateral movement of the fixed component can be controlled, which helps to accurately adjust the lateral position of the fixed component, so as to ensure that it is accurately aligned with the corresponding hanging ring and other connecting parts above the I-beam, and reduces the time and energy consumption of manual repeated adjustment and alignment. The operator can use the positioning mechanism to quickly make the fixed component reach the accurate lateral position according to the pre-set position or the actual situation on site. Compared with the method of relying on naked eye observation and rough adjustment when there is no such mechanism, it can greatly speed up the preparation work for the lifting of the I-beam, thereby improving the construction efficiency of the entire bridge construction or maintenance and other related projects, especially in the strong typhoon sea area, which has strict requirements on the operation time window.

[0025] 2. By setting up a fixing mechanism, it can be ensured that the I-beam is tightly connected to the fixed components during the lifting process, and there will be no dangerous situations such as loosening or falling off. Regardless of whether it is in the initial stress stage of lifting or when it is disturbed by external forces such as strong winds and waves during the lifting process, the fixing mechanism can firmly lock the hanging ring, so that the I-beam can be lifted steadily following the fixed components, ensuring the safe lifting and transfer of the I-beam.

[0026] 3. By setting up industrial cameras, image information of key parts such as I-beams and hanging rings can be captured in real time. In the sea environment of strong typhoons, the status of the I-beam hanging rings can be monitored in real time. Once it is found that the deflection angle of the hanging ring is too large or other conditions that do not meet safety requirements are found, early warning information can be issued in time to remind operators to take corresponding measures, such as suspending lifting operations, rechecking the fixing conditions, etc., to effectively avoid the occurrence of safety accidents and ensure the safety of lifting operations.

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Reference Figure 1-Figure 9A large-span assembled I-beam lifting system in a strong typhoon sea area comprises a gantry 1, a bridge 2 is arranged below the gantry 1, a fixing component 6 is arranged at the lower end of the lifting component of the gantry 1, a positioning mechanism 3 is arranged at the upper end of the fixing component 6, a fixing mechanism 4 is arranged at the lower end of the fixing component 6, an I-beam 5 is arranged below the fixing mechanism 4, and an industrial camera 7 is also arranged at the lower end of the fixing component 6. The positioning mechanism 3 can realize the motion control of the lateral movement of the fixing component 6, which helps to accurately adjust the lateral position of the fixing component 6, so as to ensure that it is accurately aligned with the corresponding hanging ring and other connecting parts above the I-beam 5, and reduces the time and energy consumption of manual repeated adjustment and alignment. The operator can use the positioning mechanism 3 to quickly make the fixing component 6 move according to the preset position or the actual situation on site. Component 6 reaches the accurate lateral position, which can greatly speed up the preparation work for lifting the I-beam 5, compared with the method of relying on naked eye observation and rough adjustment when there is no such mechanism, thereby improving the construction efficiency of the entire bridge construction or maintenance and other related projects, especially in the environment of strong typhoon sea area, which has strict requirements on the operation time window. It is particularly important; the industrial camera 7 can capture the image information of the I-beam 5 and key parts such as the hanging ring in real time, and monitor the status of the hanging ring of the I-beam 5 in real time in the environment of strong typhoon sea area. Once it is found that the deflection angle of the hanging ring is too large or other situations that do not meet the safety requirements are found, it can promptly issue an early warning message to remind the operator to take corresponding measures, such as suspending the lifting operation, rechecking the fixing situation, etc., to effectively avoid the occurrence of safety accidents and ensure the safety of the lifting operation.

[0039] The positioning mechanism 3 is for realizing the action of lateral movement of the fixing component 6 .

[0040] In order to fix the hanging ring provided on the upper end of the I-beam 5, the fixing mechanism 4 can ensure that the I-beam 5 is tightly connected to the fixing component 6 during the lifting process, and there will be no loosening, falling off, or other dangerous situations. Whether in the initial force stage of lifting or when disturbed by external forces such as strong winds and waves during the lifting process, the fixing mechanism 4 can firmly lock the hanging ring, so that the I-beam 5 can be lifted steadily following the fixing component 6, ensuring the safe lifting and transfer of the I-beam 5.

[0041] In this embodiment, if Figure 4-Figure 7 As shown, the fixing component 6 includes a fixing plate 60, grooves are symmetrically provided on both sides of the fixing plate 60, the lower end of the fixing plate 60 is fixedly connected to a limiting cover 61, an N-shaped groove 62 is provided on the body of the limiting cover 61 near the side of the grooves provided on both sides of the fixing plate 60, fixing grooves 63 are symmetrically provided inside the fixing plate 60, a sliding groove is provided on the lower surface of the fixing plate 60, and the inner wall of the sliding groove is connected to the inner wall of the fixing groove 63.

[0042] In this embodiment, if Figure 3As shown, each corner of the upper surface of the fixing plate 60 is fixedly connected to a gear box 31, a motor 32 is arranged on the upper surface of the gear box 31, a connecting rod 33 is fixedly connected to the outer surface of the motor 32 in a circumferential array, the lower end of the connecting rod 33 is fixedly connected to the upper surface of the gear box 31, the output shaft of the motor 32 is rotatably connected to the body of the gear box 31 through a bearing, one end of the output shaft of the motor 32 is fixedly connected to a bevel gear 1 34, the toothed surface of the bevel gear 1 34 is meshed with a bevel gear 2 35, one side of the bevel gear 2 35 is rotatably connected to the side of the gear box 31 through a bearing, wherein the two A rotating column 36 is arranged between the gear boxes 31, and both ends of the rotating column 36 are rotatably connected to the side of the gear box 31 through bearings, one end of the bevel gear 35 is fixedly connected to one end of the rotating column 36, and two connecting blocks 37 are arranged on the surface of the rotating column 36. The lower end of each connecting block 37 is fixedly connected to an electric telescopic rod 38, and the surface of the electric telescopic rod 38 is fitted with the groove surface on both sides of the fixed plate 60. The lower end of the electric telescopic rod 38 is fixedly connected to a U-shaped frame 39, and the lower end array of the U-shaped frame 39 is provided with a Mack wheel 310.

[0043] Specifically, the surface of the electric telescopic rod 38 fits with the groove surfaces on both sides of the fixed plate 60, which not only plays a guiding role, so that the electric telescopic rod 38 can only move in a straight line along the groove, but also ensures the stability of its movement. The electric telescopic rod 38 can be extended and retracted according to actual needs, and the position of the U-shaped frame 39 at its lower end can be further accurately adjusted to achieve fine adjustment of the lateral position of the fixed component 6; the Macomb wheel 310 is rotated by the motor that matches it, and the surface of the Macomb wheel 310 rolls relative to the surface of the I-beam 5, and then the gear box 31 rotatably connected to the rotating column 36 is driven to move by the electric telescopic rod 38, thereby driving the fixed plate 60 to move laterally, so that the fixing mechanism 4 can quickly and accurately reach the designated position, which can greatly speed up the preparation work for lifting the I-beam, and thus improve the construction efficiency of the entire bridge construction or maintenance and other related projects, which is particularly important in an environment such as strong typhoon waters that have strict requirements on the operation time window.

[0044] In this embodiment, the width of the opening of the U-shaped frame 39 is greater than the thickness of the upper end of the I-beam 5 .

[0045] Specifically, the larger opening width avoids the situation where the I-beam 5 is difficult to put into the U-shaped frame 39 due to size limitations, making the operation of docking the I-beam 5 with the fixing component 6 before lifting more convenient and quick to complete, reducing the time consumed in repeated adjustments due to size mismatch in the docking process, and helping to improve the overall efficiency of the entire I-beam 5 lifting operation.

[0046] In this embodiment, if Figure 4-Figure 9As shown, the fixing mechanism 4 includes a hydraulic cylinder 1 41 arranged between two electric telescopic rods 38, the lower end of the hydraulic cylinder 1 41 is fixedly connected to a hydraulic motor 42, the rotating part of the hydraulic motor 42 is fixedly connected to a nut 43, the inner wall of the fixed groove 63 is provided with a hydraulic cylinder 2 44, one end of the hydraulic cylinder 2 44 is fixedly connected to a slip ring 45, the lower end of the slip ring 45 is fixedly connected to a hook 46, the inner wall of the slide groove opened on the lower surface of the fixing plate is fixedly connected to a slide rod 47, and the inner ring surface of the slip ring 45 is slidably connected to the surface of the slide rod 47.

[0047] Specifically, when lifting the I-beam 5, the nut 43 is tightened on the screw rod, and the friction between the threads and the axial clamping force are used to firmly fix the hanging ring on the fixing mechanism 4, ensuring that the I-beam 5 will not be detached from the hanging ring under the action of external forces such as strong winds and waves, thereby ensuring the safety of the lifting operation.

[0048] In this embodiment, the lower end of the hook 46 is cylindrical, and a thread is provided on the surface of the cylinder. The lower end of the hook 46 is matched with the lower end of the nut 43.

[0049] Specifically, the lower end of the hook 46 is designed to be cylindrical and has threads. This structure is compatible with the nut 43, forming a threaded connection mode. In the lifting operation of the large-span assembled I-beam in the strong typhoon sea area, when it is necessary to fix the hanging ring of the I-beam 5, after the hook 46 is passed through the hanging ring, the nut 43 can be screwed to the thread at the lower end of the hook 46. Through the tight engagement between the threads, the stability of the connection between the hook 46 and the nut 43 can be greatly enhanced, and it is not easy to loosen or detach. The hanging ring of the I-beam 5 can be reliably fixed on the fixing mechanism 4, ensuring the safety and stability of the lifting process.

[0050] In this embodiment, the hanging ring provided at the upper end of the I-beam 5 is located between the two nuts 43 .

[0051] Specifically, placing the hanging ring at the upper end of the I-beam 5 between the two nuts 43 can achieve a symmetrical force effect.

[0052] In this embodiment, the diameter of one end of the nut 43 is smaller than the diameter of the hanging ring provided at the upper end of the I-beam 5 , and the diameter of the other end of the nut 43 is larger than the diameter of the hanging ring provided at the upper end of the I-beam 5 .

[0053] Specifically, the design that the diameter of one end of the nut 43 is smaller than the diameter of the hanging ring at the upper end of the I-beam 5 facilitates the smooth insertion of the hanging ring onto the nut 43, making the docking operation between the hanging ring and the nut 43 smoother and faster, thereby improving the working efficiency of the entire fixing link before lifting the I-beam 5. The diameter of the other end of the nut 43 is larger than the diameter of the hanging ring at the upper end of the I-beam 5. After the hanging ring is inserted, the nut 43 is rotated to make the end with the larger diameter gradually approach the hanging ring, and this part of the extra diameter space can be used to achieve the clamping effect on the hanging ring. As the nut 43 rotates, its larger diameter part will gradually apply radial pressure to the hanging ring, and the hanging ring will be tightly fixed between the two nuts 43 and in the fixed structure formed by the components related to the hook 46, ensuring that the hanging ring will not easily fall out of the nut 43 during the lifting process, thereby ensuring the stable connection between the I-beam 5 and the fixing mechanism 4.

[0054] In this embodiment, the industrial camera 7 is built with an image sensor module, an optical lens module, an image processing module, an angle calculation module, a communication module, a storage module and a control module. The image sensor module is responsible for converting the optical image into an electrical signal or a digital signal. The optical lens module is used to focus light and accurately project the image of the hanging ring onto the image sensor. The image processing module is responsible for processing the image acquired by the image sensor. The angle calculation module calculates the deflection angle of the hanging ring based on the hanging ring features extracted by the image processing module. The communication module is used for data transmission and communication with external devices. The storage module is used to save images and related data taken by the camera. The control module is mainly used to coordinate the work of various modules inside the camera.

[0055] Reference Figure 1-Figure 9 , a beam lifting method for a large-span assembled I-beam lifting system in a strong typhoon sea area, the operation steps are as follows:

[0056] Step 1: Move the I-beam 5 to one side of the bridge 2 by using a mobile device. After it is placed securely, the lifting component of the gantry 1 drives the fixed component 6 to move to the top of the I-beam 5, and then the lifting component drives the fixed component 6 to descend. Under the real-time monitoring of the industrial camera 7, the fixed component 6 descends to the specified height, and the lifting component stops working;

[0057] Step 2, the output shaft of the motor 32 drives the bevel gear 1 34 and the bevel gear 2 35 to rotate, and then drives the connection block 37 fixed to the rotating column 36 to rotate, and the electric telescopic rod 38 rotates 70 degrees under the action of the connection block 37, and the motor 32 continues to rotate to cooperate with the electric telescopic rod 38 to drive the U-shaped frame 39 to approach the I-beam 5, until the opening of the U-shaped frame 39 fits with the upper end of the I-beam 5, the motor 32 stops working, and the electric telescopic rod 38 starts to shrink until the Mack wheel 310 fits tightly with the upper end surface of the I-beam 5, and then the electric telescopic rod 38 rotates 20 degrees again, and the industrial camera 7 at this time detects whether the position of the hanging ring at the upper end of the I-beam 5 is within the preset position range;

[0058] Step 3: If the position of the hanging ring is not within the preset range, the Mack wheel 310 is moved horizontally until the hanging ring is adjusted to be located at the preset position of the industrial camera 7. If the angle of the hanging ring is not within the preset range, the industrial camera 7 sends abnormal information to the client through the communication module;

[0059] Step 4. After the hanging ring is determined by the industrial camera 7 to be within the preset range, the lifting component of the gantry 1 continues to descend until the lower end of the limit cover 61 contacts the upper surface of the I-beam 5, and the lifting component stops descending. The hydraulic cylinder 1 41 drives the nut 43 fixedly connected to the rotating component of the hydraulic motor 42 to descend to a position flush with the hanging ring, and the hydraulic cylinder 2 44 drives the slip ring 45 to move on the slide rod 47, and the lower end of the hook 46 moves through the hanging ring. After the lower end of the hook 46 enters the nut 43, the hydraulic motor 42 drives the nut 43 to rotate, and the hydraulic cylinder 2 44 continues to move until the hydraulic motor 42 stops after rotating two circles. At this time, the end with a larger diameter of the nut 43 is tightly fitted with the surface of the hanging ring. After the docking is completed, the industrial camera 7 sends a signal to the lifting component of the gantry 1 to start the lifting work.

10. The beam lifting method of a large-span assembled I-beam lifting system in strong typhoon sea area according to claim 9, characterized in that: The steps are as follows: Step 1: Move the I-beam (5) to one side of the bridge (2) by means of a mobile device. After it is placed securely, the lifting component of the gantry (1) drives the fixed component (6) to move to the top of the I-beam (5). Then, the lifting component drives the fixed component (6) to descend. Under the real-time monitoring of the industrial camera (7), the fixed component (6) descends to a specified height and the lifting component stops working. Step 2, the output shaft of the motor (32) drives the bevel gear 1 (34) and the bevel gear 2 (35) to rotate, and then drives the connection block (37) fixed to the rotating column (36) to rotate, and the electric telescopic rod (38) rotates 70 degrees under the action of the connection block (37), and the motor (32) continues to rotate to cooperate with the electric telescopic rod (38) to drive the U-shaped frame (39) close to the I-beam (5) until the opening of the U-shaped frame (39) fits with the upper end of the I-beam (5), the motor (32) stops working, and the electric telescopic rod (38) starts to shrink until the Mack wheel (310) fits tightly with the upper end surface of the I-beam (5), and then the electric telescopic rod (38) rotates 20 degrees again, and the industrial camera (7) at this time detects whether the position of the hanging ring at the upper end of the I-beam (5) is within the preset position range; Step 3: If the position of the hanging ring is not within the preset range, the Mack wheel (310) is moved laterally until the hanging ring is adjusted to be located at the preset position of the industrial camera (7); if the angle of the hanging ring is not within the preset range, the industrial camera (7) sends abnormal information to the client through the communication module; Step 4: After the hanging ring is judged by the industrial camera (7) to be within the preset range, the lifting component of the gantry (1) continues to descend until the lower end of the limit cover (61) contacts the upper surface of the I-beam (5), and the lifting component stops descending. The hydraulic cylinder 1 (41) drives the nut (43) fixedly connected to the rotating component of the hydraulic motor (42) to descend to a position flush with the hanging ring. The hydraulic cylinder 2 (44) drives the slip ring (45) to move on the slide rod (47), and the lower end of the hook (46) moves through the hanging ring. After the lower end of the hook (46) enters the nut (43), the hydraulic motor (42) drives the nut (43) to rotate, and the hydraulic cylinder 2 (44) continues to move until the hydraulic motor (42) stops after rotating two circles. At this time, the end with a larger diameter of the nut (43) is tightly fitted with the surface of the hanging ring. After the docking is completed, the industrial camera (7) sends a signal to the lifting component of the gantry (1) to start the lifting work.
