Description

Technical Field

[0001] The present invention relates to the technical field of steel component hoisting, and particularly to a device for the smooth turning-over of overweight steel structure components without impact by a traveling crane. Background Art

[0002] In the field of modern industrial construction, overweight steel structure components are widely used in projects such as bridge construction, large factory building erection, and high-rise building construction due to their advantages of high strength, high stability, etc. During the installation process of the components, the turning-over operation is a key and challenging operation, and its operation effect directly affects the project quality and construction safety.

[0003] Traditional methods for turning over overweight steel structure components mostly rely on directly hoisting and turning them by lifting equipment or using simple mechanical auxiliary devices. These methods have many drawbacks. When directly dragging and turning by lifting equipment, the components are extremely likely to generate violent shaking and swinging instantaneously. The powerful inertial impact may not only cause damage and deformation on the surface of the components, reducing the quality of the components, but also impose additional loads and losses on the lifting equipment, shortening the service life of the equipment; at the same time, the uncontrollable shaking increases the safety risks during the construction process, easily triggering safety accidents and threatening the lives of construction workers. And simple mechanical auxiliary devices often lack precise positioning and adjustment functions, are difficult to adapt to components of different specifications and shapes, cannot ensure the smoothness of the components during the turning-over process, and usually can only achieve turning over at a fixed angle, making it difficult to meet the diverse installation requirements in complex construction environments, resulting in low construction efficiency.

[0004] With the continuous improvement of the requirements for project quality and construction efficiency in modern industry, the traditional turning-over technology has been difficult to meet the development needs. In addition, the scale of construction projects is increasing day by day, and the size and weight of overweight steel structure components are constantly increasing, which puts forward higher requirements for the bearing capacity, stability, and operation flexibility of the turning-over device. Therefore, it is extremely urgent to develop a device that can achieve the smooth turning-over of overweight steel structure components without impact and at the same time has characteristics such as precise positioning, flexible adjustment, and wide adaptability.

[0005] The device for the smooth turning-over of overweight steel structure components without impact by a traveling crane proposed by the present invention is precisely designed to solve the above problems. Through innovative structural design and working principles, it endeavors to overcome the defects of traditional technologies, provide a safer, more efficient, and reliable solution for the turning-over operation of overweight steel structure components, meet the continuous development needs of modern industrial construction, and promote technological progress and industrial upgrading in related fields. Summary of the Invention

[0006] The purpose of the present invention is to provide an abnormal detection method for industrial control systems based on instruction grouping. By rotating the motor to drive the lead screw to adjust the position of the component connection platform, the air cylinder drives the toothed plate to engage with the semi-circular gear to adjust the table surface angle. After fixing the component, the motor drives the lead screw to lift the component, and the pulling handle of the traveling crane pulling device is pulled to make it roll and drive the component to flip. The vehicle can stop at any angle, and finally, the position of the connection platform is adjusted by the motor and the lead screw to lower the component, realizing the shock-free and stable turning over of the overweight steel structure component by the traveling crane.

[0007] To achieve the above object, the present invention provides the following technical solutions: An apparatus for shock-free and stable turning over of an overweight steel structure component by a traveling crane, comprising a disc-shaped outer frame and a disc-shaped inner frame. The disc-shaped outer frame and the disc-shaped inner frame are fixedly connected by a connecting wall, and an internal cavity is formed inside the connecting wall. It is characterized in that a pulling handle is fixedly installed at the center of the outer side of the disc-shaped outer frame, a sliding groove is arranged on the outer side of the disc-shaped inner frame, a through groove is arranged inside the sliding groove, the through groove penetrates the disc-shaped inner frame, a connecting component is slidably and guidingly connected in the sliding groove, the connecting component passes through the through groove and enters the internal cavity, and a driving component is fixedly installed in the internal cavity, and the driving component is drivingly connected with the connecting component; The connecting component includes a connecting seat, the connecting seat is slidably and fittingly connected into the sliding groove, a convex platform extends from the bottom of the connecting seat, the convex platform passes through the through groove and enters the internal cavity, and a threaded hole is opened on the convex platform; connecting ears are arranged on both sides of the connecting seat, a component connection platform is rotatably installed between the connecting ears, the bottom of the component connection platform is a semi-circular gear, a cylinder is fixedly installed perpendicular to the component connection platform on the connecting seat, and a toothed plate is fixedly installed on the telescopic shaft of the installation cylinder, and the toothed plate meshes with the semi-circular gear at the bottom of the component connection platform; The driving component includes a rotating motor, the rotating motor is fixedly installed on the inner side of the disc-shaped inner frame, a lead screw is fixedly installed on the rotating shaft of the rotating motor, and the lead screw passes through the threaded hole of the convex platform extending from the bottom of the connecting seat and is screwed with it.

[0008] There are a pair of the devices, and the pair of devices are used in cooperation.

[0009] A plurality of threaded holes are arranged on the table surface of the component connection platform, and the component is fixed through the threaded holes.

[0010] A bearing is sleeved and installed on the pulling handle.

[0011] A round table is arranged at the end of the pulling handle, and the diameter of the round table is larger than the diameter of the pulling handle.

[0012] Hollow grooves are arranged on the disc-shaped outer frame and the connecting wall.

[0013] The connecting wall is provided with a through hole corresponding to the top position of the lead screw, and the top end of the lead screw passes through the through hole of the connecting wall and is rotatably connected thereto.

[0014] Platforms are provided on the outer surfaces of the upper and lower ends of the disc-shaped outer frame and the disc-shaped inner frame.

[0015] The upper surface of the component connecting table is provided with an anti-slip rubber pad, and the surface of the anti-slip rubber pad layer is provided with patterns.

[0016] A centering chuck is fixedly installed on the component connecting table, and the number of jaws of the centering chuck is selected according to the shape of the component.

[0017] First, a pair of devices are symmetrically placed on both sides of the component to be flipped, and the rotation motor is started, which drives the lead screw to rotate. Since the lead screw is screwed into the threaded hole of the boss at the bottom of the connecting seat, the connecting seat slides smoothly along the lead screw direction in the sliding groove, so as to accurately adjust the position of the component connecting table. Then, the telescopic shaft of the cylinder extends out, driving the rack fixedly connected thereto to move. The rack meshes with the semi-circular gear at the bottom of the component connecting table, converting the linear motion of the rack into the rotation of the component connecting table, so as to adjust the table top of the component connecting table to an appropriate angle. Subsequently, the component is firmly fixed on the component connecting table. For components that cannot be fixed to the component connecting table with bolts, a centering chuck is fixedly installed on the component connecting table, and the component is clamped and fixed through the centering chuck. After the fixing is completed, the rotation motor drives the lead screw to rotate again, and the component is smoothly lifted. At this time, the hook of the traveling crane pulls the pulling handle of a pair of devices through a rope or the like. The bearing sleeved on the pulling handle reduces the pulling resistance. Under the action of the pulling force, the device rolls, thereby driving the component to flip, and the component can be stopped at any angle at any time. Platforms are provided on the outer surfaces of the upper and lower ends of the disc-shaped outer frame and the disc-shaped inner frame. When the component reaches the fully flipped state, the device gets stuck due to the platform, making it flip precisely. After the device finishes flipping, the rotation motor drives the lead screw to rotate, and by using the screwing relationship between the lead screw and the threaded hole of the boss at the bottom of the connecting seat, the connecting seat is driven to slide in the sliding groove, and the position of the component connecting table is adjusted again. Finally, the component is smoothly put down, completing the entire non-impact and smooth flipping process.

[0018] Compared with the prior art, the beneficial effects of the present invention are: Through the threaded drive of the lead screw and the connecting seat driven by the rotation motor, the position of the component connecting table can be finely adjusted. Compared with the traditional positioning method relying on manual or simple machinery, it can more accurately adapt to overweight steel structure components of different specifications and shapes, and the adjustment process is stable and controllable, effectively avoiding installation errors and safety hazards caused by positioning deviations.

[0019] The rotation of the component connection platform is realized by the combination of a cylinder, a toothed plate and a semi-circular gear. During the turning-over process, by precisely controlling the telescoping of the cylinder, the component can be flipped in a stable and uniform state. Compared with the traditional method of directly dragging the component by a lifting device, which causes severe shaking of the component, the inertial impact during the flipping process is significantly reduced, the risk of component damage due to impact is lowered, and the quality of the component and the operation safety are ensured.

[0020] The device can stop at any time during the turning-over process pulled by the overhead crane, making the component stop at any angle, breaking the limitation that the traditional turning-over device can only complete the turning-over at a fixed angle. This flexibility greatly expands the application scenarios of the device, can meet the requirements of different installation angles of components in complex construction environments, can achieve precise multi-angle installation without additional auxiliary equipment, and improves the construction efficiency.

[0021] When a pair of devices are used in combination and combined with the pulling of the overhead crane, a complete and efficient turning-over operation system is formed. Compared with a single device or a decentralized operation mode, this collaborative working method can distribute the force more evenly, effectively avoid problems such as tilting and twisting of the component during the turning-over process, simplify the operation process at the same time, reduce the labor input, and improve the overall operation efficiency.

[0022] Multiple threaded holes are provided on the surface of the component connection platform, and it can be fixedly connected with various types of overweight steel structure components through bolts of different specifications, with strong adaptability; at the same time, the modular design of the device makes it easy to disassemble, assemble and transport, and can be quickly applied to different construction sites. Compared with special turning-over equipment, it has higher versatility and a wider application range, reducing the enterprise's equipment procurement and maintenance costs.

The connecting component 2 passes through the through groove 122 and enters the internal cavity. A driving component 3 is fixedly installed in the internal cavity. The driving component 3 is drivingly connected with the connecting component 2; The connecting component 2 includes a connecting seat 21. The connecting seat 21 is slidably connected to the sliding groove 121. A convex platform extends from the bottom of the connecting seat 21. The convex platform passes through the through groove 122 and enters the internal cavity. A threaded hole is opened on the convex platform; Connecting ears are arranged on both sides of the connecting seat 21. A component connecting platform 22 is rotatably installed between the connecting ears. The bottom of the component connecting platform 22 is a semi-circular gear. A cylinder 23 is fixedly installed on the connecting seat 21 perpendicular to the component connecting platform 22. A toothed plate 24 is fixedly installed on the telescopic shaft of the mounting cylinder 23. The toothed plate 24 meshes with the semi-circular gear at the bottom of the component connecting platform 22; The driving component 3 includes a rotating motor 31. The rotating motor 31 is fixedly installed on the inner side of the disc-shaped inner frame 12. A lead screw 32 is fixedly installed on the rotating shaft of the rotating motor 31. The lead screw 32 passes through the threaded hole of the convex platform extending from the bottom of the connecting seat 21 and is screwed with it.

[0026] The devices are in a pair and the pair of devices are used in cooperation.

[0027] A plurality of threaded holes are arranged on the table surface of the component connecting platform 22, and are fixed to the component through the threaded holes.

[0028] A bearing 41 is sleeved and installed on the pulling handle 4.

[0029] A frustum is provided at the end of the pulling handle 4, and the diameter of the frustum is larger than that of the pulling handle 4.

[0030] Hollow slots are provided in the disc-shaped outer frame 11 and the connecting wall 13.

[0031] A through hole is provided in the connecting wall 13 corresponding to the top position of the lead screw 32, and the top of the lead screw 32 passes through the through hole in the connecting wall 13 and is rotatably connected thereto.

[0032] Platforms are provided on the outer surfaces of the upper and lower ends of the disc-shaped outer frame 11 and the disc-shaped inner frame 12.

[0033] An anti-slip rubber pad is provided on the upper surface of the component connecting platform 22, and patterns are provided on the surface of the anti-slip rubber pad layer.

[0034] A centering chuck 221 is fixedly installed on the component connecting platform 22, and the number of jaws of the centering chuck 221 is selected according to the shape of the component.

[0035] During specific implementation, first, a pair of non-impact and stable turning devices for overweight steel structure components are symmetrically placed on both sides of the component to be turned over, and the reinforcing rib structure between the disc-shaped outer frame 11 and the disc-shaped inner frame 12 is used to ensure the stable support of the device. The rotation motor 31 is started, which drives the lead screw 32 to rotate. Since the lead screw 32 is screwed with the threaded hole of the boss at the bottom of the connecting seat 21, the connecting seat 21 slides smoothly along the sliding groove 121, and the position of the component connecting platform 22 is accurately adjusted; then the air cylinder 23 is started, and the telescopic shaft drives the toothed plate 24 to move linearly. Through the meshing transmission between the toothed plate 24 and the semi-circular gear at the bottom of the component connecting platform 22, the linear motion is converted into the rotation of the component connecting platform 22, and then the tabletop is adjusted to an appropriate angle. Then, through the threaded hole on the tabletop of the component connecting platform 22, the component is firmly fixed with bolts. For components that cannot be fixed to the component connecting platform with bolts, a centering chuck 221 is fixedly installed on the component connecting platform, and the component is clamped and fixed through the centering chuck 221. The rotation motor 31 is started again, and the rotation of the lead screw 32 drives the connecting seat 21 to move upward, and the component is smoothly lifted. At this time, the hoisting hook of the crane pulls the pulling handle 4 through the rope, and the bearing 41 on the pulling handle 4 reduces the pulling resistance, and the device rolls under the pulling force, driving the component to turn over. During this period, the vehicle can be stopped at any time to make the component stop at any angle. When the component is turned over to the predetermined angle, the platforms on the outer surfaces of the upper and lower ends of the disc-shaped outer frame 11 and the disc-shaped inner frame 12 produce jamming, realizing accurate turning-over positioning. Finally, the rotation motor 31 rotates the lead screw 32 in the reverse direction, driving the connecting seat 21 to move downward, and the component is smoothly lowered, completing the entire non-impact and stable turning-over process. During the whole process, the hollow slots provided in the disc-shaped outer frame 11 and the connecting wall 13 reduce the weight of the device, and the anti-slip rubber pad on the upper surface of the component connecting platform 22 ensures the stability when the component is fixed. The components cooperate with each other to ensure the high efficiency and safety of the operation.
