Description

Technical Field

[0001] This invention relates to the field of airport construction technology, and more specifically, to a safe and protective hoisting device and method for transporting steel structures for airport construction. Background Technology

[0002] Airport construction refers to a series of tasks including planning, design, construction, and renovation of airports. This includes the construction of numerous infrastructure facilities such as runways, aprons, terminals, and control towers. During the airport construction process, the transfer and hoisting of steel structures is a crucial link that directly affects the quality and safety of airport construction. This steel structure transfer safety protection hoisting equipment and method based on airport construction was developed to better complete this link.

[0003] According to patent document CN120613661A, a self-propelled high-voltage cable laying device addresses the issues of fixed cable reel positions (currently using fixed laying frames, where the cable reel's position is fixed and cannot be adjusted later), lack of adaptive cable reel adjustment, automatic cable reel leveling, and cable reel braking. The proposed solution includes a tracked walking device, an upper frame, a hoisting mechanism, and a cable reel support. The tracked walking device is horizontally positioned on the ground, and the upper frame is mounted on it. In this invention, the cable reel support achieves independent height and spacing adjustment through a lifting mechanism (lifting cylinder + inner rod and outer cylinder structure) and a retraction / unwinding mechanism (telescopic cylinder + slider groove), adapting to different cable reel specifications. Automatic leveling is achieved through an electronic control system, preventing equipment damage or operation interruption due to uneven load.

[0004] During airport construction, a large amount of steel structure materials are needed to construct various buildings and facilities. These steel structures face numerous severe challenges during transportation. Due to the complexity of the airport environment, relatively limited space, and extremely high requirements for construction safety and efficiency, traditional hoisting equipment often fails to meet the actual needs. Specifically, traditional hoisting equipment typically uses a hoisting machine to lift the hoisting platform to the required height, and the steel structure materials are placed directly on the hoisting platform. However, during transportation, due to the lack of effective fixing measures, these steel structures are prone to swaying, displacement, or even falling in the complex airport environment, posing a significant safety hazard. This not only affects the construction progress but may also seriously threaten the safety of on-site personnel. Therefore, how to effectively solve the safety problem of steel structure transportation in airport construction has become an important issue that urgently needs to be addressed. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a safety-protected hoisting equipment and method for the transfer of steel structures in airport construction. The technical problem to be solved by this invention is that during the transfer process, due to the lack of effective fixing measures, these steel structures are prone to shaking, displacement, or even falling in the complex airport environment, which brings great safety hazards. This not only affects the construction progress but may also pose a serious threat to the safety of on-site personnel. Therefore, how to effectively solve the safety problem of steel structure transfer in airport construction is the key issue.

[0019] In addition, the present invention also relates to a method of using a steel structure transfer safety protection hoisting equipment based on airport construction, comprising the following steps:

[0020] Step 1: First, conduct a comprehensive survey of the hoisting site to determine the specific location, size, weight of the steel structure, and surrounding environmental conditions. Based on the survey results, develop a detailed hoisting plan, specifying the parking location of the hoisting machine, the hoisting route, and safety protection measures.

[0021] Step 2: Transport the hoist to the hoisting site and park it precisely in the appropriate position according to the established plan. Conduct a comprehensive inspection of the hoist to ensure that all its components are firmly connected and in good working order. At the same time, carefully adjust the hoisting connectors, hoisting platform and bottom limit components to ensure smooth operation.

[0022] Step 3: The operator starts the hoisting machine through professional control equipment and slowly lowers the hoisting connector, which in turn drives the hoisting platform and bottom limit component to gradually descend. The inner sides of the two clamping plates can accurately correspond to the two sides of the steel structure.

[0023] Step 4: Once the hoisting platform reaches the appropriate height, start the motor. The motor drives the drive shaft to rotate, and the drive shaft transmits power to the two drive rings through two tracks, driving the two columnar rotating rods to rotate. The two columnar rotating rods drive the two sets of turntables to rotate synchronously. The rotating blocks on the turntables perform circular motion, which pulls multiple sets of rotating vertical plates to rotate through two sets of bidirectional hinged rods. The multiple sets of rotating vertical plates drive the elliptical connecting blocks to move, causing the two sets of U-shaped expansion and contraction plates to retract inward.

[0024] Step 5: As the two sets of U-shaped expansion plates retract inward, the abutment plate moves inward, pushing the V-shaped rotating rod to rotate around the hinge block, causing the bottom support block to rise and lock into the bottom of the steel structure. At the same time, the two sets of U-shaped expansion plates drive the two sets of push-pull rotating rods to rotate, pushing the two clamping plates to move inward. The clamping plate slider slides in the guide groove of the rectangular guide plate to ensure accurate and stable clamping action.

[0025] Step Six: The clamping plate continues to move inward, and the vacuum suction cups on its inner side gradually approach the surface of the steel structure. The vacuum adsorption control device is activated, and a negative pressure environment is created inside the vacuum suction cups through the pipes, so that they are firmly adsorbed on both sides of the steel structure.

[0026] Step 7: Conduct a comprehensive inspection of the hoisting equipment's fixation again. After confirming that the steel structure has been firmly fixed by both mechanical clamping and vacuum adsorption, and that the bottom support blocks reliably support the bottom of the steel structure, the operator slowly raises the hoisting machine by controlling the equipment to lift the steel structure smoothly.

[0027] Step 8: After reaching the designated position, slowly lower the steel structure. When the steel structure is close to the ground, pause the descent, release the negative pressure environment of the vacuum suction cup, and separate the vacuum suction cup from the steel structure. Then, reverse the operation of the motor to restore each component to its initial state and place the steel structure smoothly on the designated position on the ground, completing one steel structure transfer and hoisting operation.

[0028] The beneficial effects of this invention are as follows:

[0029] This invention, by incorporating a hoisting machine, hoisting connectors, a hoisting platform, and a bottom limit assembly, organically combines mechanical clamping and vacuum adsorption through precise mechanical linkage and intelligent control technology. This provides a comprehensive and highly stable safety solution for the transfer of steel structures during airport construction. In practical applications, this equipment not only effectively prevents deformation or damage to the steel structure due to uneven local stress during hoisting, but also significantly improves the overall safety of the hoisting operation through a dual-fixing mechanism. Furthermore, the coordinated work between the various components ensures the smoothness and precision of the hoisting process, greatly improving construction efficiency. In addition, this hoisting equipment and method are easy to operate and highly adaptable, meeting the transfer needs of steel structures of different sizes and shapes, providing solid technical support for the smooth progress of airport construction projects.

Bottom support blocks 43 are fixedly connected to the bottom of the inner sides of the left and right sets of V-shaped rotating rods 41.

[0044] During airport construction, when the steel structure needs to be transferred, the hoist 1 must first be precisely moved to the designated construction position. Then, the operator starts the hoist 1 and gradually lowers the hoisting connector 2, hoisting platform 3, and bottom limit assembly 4, ensuring that the inner sides of the two clamping plates 3217 of the hoisting platform 3 precisely correspond to the two sides of the steel structure. Next, the motor 317 is started, which drives the drive shaft 318 to rotate. The drive shaft 318 efficiently transmits power to the two drive rings 323 via two tracks 319, thereby driving the two columnar rotating rods 322 to rotate. The rotation of the two columnar rotating rods 322 drives the two sets of turntables 324 to rotate synchronously. The rotating blocks 325 on the two sets of turntables 324 then perform circular motion, which is controlled by the pull of two sets of bidirectional hinged rods 326. The action involves multiple sets of rotating upright plates 327 starting to rotate. The rotation of the multiple sets of rotating upright plates 327 further drives the elliptical connecting block 329 to move, thereby causing the two sets of U-shaped expansion plates 3210 to retract inward. When the two sets of U-shaped expansion plates 3210 retract inward, the abutment plate 3213 also moves inward, pushing the V-shaped rotating rod 41 to rotate around the hinge block 3114, causing the bottom support block 43 to rise and be clamped at the bottom of the steel structure. At the same time, during the inward movement of the two sets of U-shaped expansion plates 3210, the two sets of push-pull rotating rods 3215 will also rotate, thereby pushing the two clamping plates 3217 to move inward. During the inward movement of the two clamping plates 3217, the clamping plate slider 3218 slides stably in the guide groove 3118 of the rectangular guide plate, ensuring the accuracy and stability of the clamping action.

[0045] As the clamping plate 3217 continues to move inward, the vacuum suction cup 3219 on its inner side gradually approaches the surface of the steel structure. At this time, the vacuum adsorption control component 3115 is activated, and a negative pressure environment is formed inside the vacuum suction cup 3219 through the pipe 3116, thereby firmly adsorbing it onto both sides of the steel structure. This dual fixing method, which combines mechanical clamping and vacuum adsorption, not only significantly improves the overall stability during the hoisting process, but also effectively avoids deformation or damage to the steel structure due to excessive local stress by dispersing the force. When the hoisting machine 1 lifts the steel structure smoothly, the V-shaped rotating rod 41 always maintains a close fit with the abutment plate 3213, thereby ensuring reliable support of the bottom support block 43 for the bottom of the steel structure. The entire hoisting system, through the combination of precise mechanical linkage design and intelligent control technology, realizes the safe and efficient transfer of the steel structure from the ground to the air, providing a strong guarantee for the smooth progress of the airport construction project.

[0046] In addition, the present invention also relates to a method of using a steel structure transfer safety protection hoisting equipment based on airport construction, comprising the following steps:

[0047] Step 1: First, conduct a comprehensive survey of the hoisting site to determine the specific location, size, weight of the steel structure, and surrounding environment. Based on the survey results, formulate a detailed hoisting plan, specifying the parking location of hoisting machine 1, the hoisting route, and safety protection measures.

[0048] Step 2: Transport the hoist 1 to the hoisting site and park it precisely in the appropriate position according to the established plan. Conduct a comprehensive inspection of the hoist 1 to ensure that all its components are firmly connected and in good working order. At the same time, carefully adjust the hoisting connector 2, hoisting platform 3 and bottom limit assembly 4 to ensure smooth operation.

[0049] Step 3: The operator starts the hoist 1 through professional control equipment, slowly lowers the hoisting connector 2, and then drives the hoisting platform 3 and the bottom limit component 4 to gradually descend. The inner sides of the two clamping plates 3217 can accurately correspond to the two sides of the steel structure.

[0050] Step 4: When the hoisting platform 3 reaches the appropriate height, start the motor 317. The motor 317 drives the transmission shaft 318 to rotate. The transmission shaft 318 transmits power to the two transmission rings 323 through the two tracks 319, driving the two columnar rotating rods 322 to rotate. The two columnar rotating rods 322 drive the two sets of turntables 324 to rotate synchronously. The rotating blocks 325 on the turntables 324 perform circular motion, which pulls the multiple sets of rotating vertical plates 327 to rotate through the two sets of bidirectional hinge rods 326. The multiple sets of rotating vertical plates 327 drive the elliptical connecting blocks 329 to move, causing the two sets of U-shaped expansion and contraction plates 3210 to retract inward.

[0051] Step 5: As the two sets of U-shaped expansion plates 3210 retract inward, the abutment plate 3213 moves inward, pushing the V-shaped rotating rod 41 to rotate around the hinge block 3114, causing the bottom support block 43 to rise and be locked at the bottom of the steel structure. At the same time, the two sets of U-shaped expansion plates 3210 drive the two sets of push-pull rotating rods 3215 to rotate, pushing the two clamping plates 3217 to move inward. The clamping plate slider 3218 slides in the guide groove 3118 of the rectangular guide plate to ensure accurate and stable clamping action.

[0052] Step 6: The clamping plate 3217 continues to move inward, and the vacuum suction cup 3219 on its inner side gradually approaches the surface of the steel structure. The vacuum adsorption control component 3115 is activated, and a negative pressure environment is formed inside the vacuum suction cup 3219 through the pipe 3116, so that it is firmly adsorbed on both sides of the steel structure.

[0053] Step 7: Conduct a comprehensive inspection of the hoisting equipment's fixation again. After confirming that the steel structure has been firmly fixed by both mechanical clamping and vacuum adsorption, and that the bottom support block 43 reliably supports the bottom of the steel structure, the operator slowly lifts the hoisting machine 1 through the control equipment to lift the steel structure smoothly.

[0054] Step 8: After reaching the designated position, slowly lower the steel structure. When the steel structure is close to the ground, pause the descent, release the negative pressure environment of the vacuum suction cup 3219, and separate the vacuum suction cup 3219 from the steel structure. Then, reverse the operation of the motor 317 to restore each component to its initial state and place the steel structure stably on the designated position on the ground, completing one steel structure transfer and hoisting operation.

[0055] Working principle of this invention: During airport construction, when the steel structure needs to be transferred, the hoist 1 must first be precisely moved to the predetermined construction position. Then, the operator controls the hoist 1 to start, gradually lowering the hoisting connector 2, hoisting platform 3, and bottom limit assembly 4, ensuring that the inner sides of the two clamping plates 3217 of the hoisting platform 3 precisely correspond to the two sides of the steel structure. Next, the motor 317 is started, driving the transmission shaft 318 to rotate. The transmission shaft 318 efficiently transmits power to the two transmission rings 323 via two tracks 319, thereby driving the two columnar rotating rods 322 to rotate. The rotation of the two columnar rotating rods 322 drives the two sets of turntables 324 to rotate synchronously. The rotating blocks 325 on the two sets of turntables 324 then perform circular motion. Through the pulling action of the two sets of bidirectional hinged rods 326, multiple rotating upright plates 327 begin to rotate. The rotation of the multiple rotating upright plates 327 further drives... The elliptical connecting block 329 moves, causing the two sets of U-shaped expansion plates 3210 to retract inward. As the two sets of U-shaped expansion plates 3210 retract inward, the abutment plate 3213 also moves inward, pushing the V-shaped rotating rod 41 to rotate around the hinge block 3114, causing the bottom support block 43 to rise and lock into place at the bottom of the steel structure. Simultaneously, as the two sets of U-shaped expansion plates 3210 move inward, they also drive the two sets of push-pull rotating rods 3215 to rotate, further... As the two clamping plates 3217 are pushed inward, the clamping plate sliders 3218 slide stably within the guide grooves 3118 of the rectangular guide plate during the inward movement. As the clamping plates 3217 continue to move inward, the vacuum suction cups 3219 on their inner sides gradually approach the surface of the steel structure. At this time, the vacuum adsorption control component 3115 is activated, and a negative pressure environment is formed inside the vacuum suction cups 3219 through the pipes 3116, thereby firmly adsorbing them onto both sides of the steel structure.

3. The method of using the steel structure transfer safety protection hoisting equipment based on airport construction as described in claim 2, characterized in that: Includes the following steps: Step 1: First, conduct a comprehensive survey of the hoisting site to determine the specific location, size, weight of the steel structure, and surrounding environmental conditions. Based on the survey results, develop a detailed hoisting plan, specifying the parking location of the hoisting machine, the hoisting route, and safety protection measures. Step 2: Transport the hoist to the hoisting site and park it precisely in the appropriate position according to the established plan. Conduct a comprehensive inspection of the hoist to ensure that all its components are firmly connected and in good working order. At the same time, carefully adjust the hoisting connectors, hoisting platform and bottom limit components to ensure smooth operation. Step 3: The operator starts the hoisting machine through professional control equipment and slowly lowers the hoisting connector, which in turn drives the hoisting platform and bottom limit component to gradually descend. The inner sides of the two clamping plates can accurately correspond to the two sides of the steel structure. Step 4: Once the hoisting platform reaches the appropriate height, start the motor. The motor drives the drive shaft to rotate, and the drive shaft transmits power to the two drive rings through two tracks, driving the two columnar rotating rods to rotate. The two columnar rotating rods drive the two sets of turntables to rotate synchronously. The rotating blocks on the turntables perform circular motion, which pulls multiple sets of rotating vertical plates to rotate through two sets of bidirectional hinged rods. The multiple sets of rotating vertical plates drive the elliptical connecting blocks to move, causing the two sets of U-shaped expansion and contraction plates to retract inward. Step 5: As the two sets of U-shaped expansion plates retract inward, the abutment plate moves inward, pushing the V-shaped rotating rod to rotate around the hinge block, causing the bottom support block to rise and lock into the bottom of the steel structure. At the same time, the two sets of U-shaped expansion plates drive the two sets of push-pull rotating rods to rotate, pushing the two clamping plates to move inward. The clamping plate slider slides in the guide groove of the rectangular guide plate to ensure accurate and stable clamping action. Step Six: The clamping plate continues to move inward, and the vacuum suction cups on its inner side gradually approach the surface of the steel structure. The vacuum adsorption control device is activated, and a negative pressure environment is created inside the vacuum suction cups through the pipes, so that they are firmly adsorbed on both sides of the steel structure. Step 7: Conduct a comprehensive inspection of the hoisting equipment's fixation again. After confirming that the steel structure has been firmly fixed by both mechanical clamping and vacuum adsorption, and that the bottom support blocks reliably support the bottom of the steel structure, the operator slowly raises the hoisting machine by controlling the equipment to lift the steel structure smoothly. Step 8: After reaching the designated position, slowly lower the steel structure. When the steel structure is close to the ground, pause the descent, release the negative pressure environment of the vacuum suction cup, and separate the vacuum suction cup from the steel structure. Then, reverse the operation of the motor to restore each component to its initial state and place the steel structure smoothly on the designated position on the ground, completing one steel structure transfer and hoisting operation.
