Description

Technical Field

[0001] This invention relates to the field of steel structure processing technology, specifically a flipping mechanism for steel structure processing. Background Technology

[0002] Steel structure engineering is one of the main types of building structures and one of the most common structural forms in modern construction engineering. Steel structure engineering is a structure mainly made of steel. Steel is characterized by high strength, light weight, good overall rigidity and strong deformation capacity, so it is particularly suitable for building large-span, super-high and super-heavy buildings. However, steel needs to be processed by processing equipment before use. Existing processing equipment is not convenient for flipping and adjusting steel structures when processing steel, which makes it difficult to process steel at different angles and reduces the practicality of the equipment.

[0003] To this end, Chinese Patent Publication No. CN218370279U discloses a "Tilting Mechanism for Steel Structure Processing". Its main structure includes a base, with support columns on both the left and right sides of the top of the base. A transmission rod is positioned between the two support columns, and a transmission roller is positioned on the outer side of the transmission rod. Two fixed columns are positioned on the top of the base, located in front of the transmission roller. Guide rollers are positioned on opposite sides of the fixed columns on both the left and right sides. Two electric hydraulic cylinders are positioned on the top of the base, located on the front and rear sides of the transmission roller. An adjustment assembly extends into the interior of the two support columns and is movably connected to their inner walls. A control assembly extends to the opposite sides of the two support columns on the inner side of the adjustment assembly. This tilting mechanism for steel structure processing, by setting the transmission roller and guide roller, allows the user to place steel structure materials on the transmission roller, positioned on the left and right sides. The guide rollers on both sides move to the designated position, and then the electric hydraulic cylinder is activated to lift the steel structure. The electric push rod then moves the clamping assembly to the upper and lower sides of the steel structure. The user can then control the rotating block to drive the bidirectional screw to rotate. The bidirectional screw, through two moving plates, drives two clamping blocks to move to opposite sides and clamp the steel structure. At this point, the dual-axis servo motor is activated to drive the rotating rod to rotate. The rotating rod, through the driving and driven wheels, drives the threaded rod to rotate. The threaded rod drives the threaded block to move upward, causing the clamping assembly to move the steel structure upward to a suitable distance. Then, the servo motor is activated. The servo motor, through two meshing gears, drives the rotating shaft to rotate. The rotating shaft, through the mounting base and the electric push rod, drives the clamping assembly and the steel structure to perform a flipping operation. This effectively helps the user adjust and flip the operation according to the size of the steel structure, reducing the labor intensity of the workers.

[0004] However, in actual use, the aforementioned steel structure processing flipping mechanism uses meshing gears to drive the rotating shaft to rotate. The rotating shaft drives the clamping assembly and steel structure to flip through the mounting base and electric push rod. After the steel structure is flipped, it can only rely on the anti-rotation resistance generated by the motor when it is turned off to keep the steel plate in a stationary state. However, when processing the steel structure, this anti-rotation resistance is not very effective in maintaining stability, which can easily cause the steel structure to flip. Therefore, its stability in the working state is relatively poor. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a flipping mechanism for steel structure processing. Utilizing electromagnetic principles, it can fix steel structures by adsorption, thus achieving a fixing effect on steel structures of different sizes. Furthermore, the device uses the relative friction between the rotating and stationary discs to control the static state of the steel structure after flipping, providing appropriate frictional resistance according to actual conditions.

[0027] To achieve an adsorption-based fixation effect on the steel structure, please refer to... Figure 1 , Figure 2 and Figure 3 An electromagnetic fixing mechanism 4 is required, which includes a horizontal connecting shaft 41 connected to two arm-shaped supports 3 via bearings, an electromagnetic coil 45 installed at both ends of the horizontal connecting shaft 41 and capable of carrying current, an electromagnetic iron core 46 fixedly installed at the center of the electromagnetic coil 45 and generating a magnetic field after current is passed through the electromagnetic coil 45, a hand crank 48 fixedly installed on one side of one of the electromagnetic coils 45 and capable of driving the electromagnetic iron core 46 to rotate, and a rotating disk 49 fixedly installed on one side of the other electromagnetic coil 45.

During operation, the two terminals of the electromagnetic coil 45 are respectively connected to the current output terminal of a current controller that can control the direction and magnitude of the current through wires. When the bottom of the shaft mounting sleeve 42 contacts the steel structure, the current controller is turned on. According to the electromagnetic principle, the two ends of the electromagnetic iron core 46 will generate magnetism, causing the steel structure to be tightly attracted to the bottom of the shaft mounting sleeve 42, thereby achieving an adsorption-type fixing effect on the steel structure.

[0028] For details regarding the specific structure of the electromagnetic fixing mechanism 4, please refer to [link / reference]. Figure 2 and Figure 3The system includes a horizontal connecting shaft 41, on which shaft mounting sleeves 42 are mounted via bearings near both ends. A first docking plate 43 is fixedly mounted on the circumferential surface of the shaft mounting sleeves 42. An electromagnetic housing 44 is fixedly mounted at each end of the horizontal connecting shaft 41. An electromagnetic coil 45 is fixedly mounted at the center of each electromagnetic housing 44. An electromagnetic core 46 is fixedly mounted at the center of each electromagnetic coil 45. An annular buffer pad 47 is mounted on the bottom of the electromagnetic housing 44 around the electromagnetic core 46.

Figure 1 , Figure 4 and Figure 5 A hydraulic braking mechanism 5 is required, which includes a horizontal hollow body 51 fixedly installed in the fixed base 1 and having a hollow internal structure; a helical spring 510 placed inside the horizontal hollow body 51 and providing elasticity; a second telescopic rod 512 capable of moving axially along the horizontal hollow body 51 and having one end subjected to the elastic force of the helical spring 510; a stationary disc 513 installed at the end of the second telescopic rod 512 and able to abut against the rotating end face of the rotating disc 49; and a piston body 57 placed inside the horizontal hollow body 51 and capable of changing the elastic strength of the helical spring 510 after being subjected to hydraulic pressure. Before operation, the liquid flow channel 53 needs to be connected to the liquid circuit of a hydraulic pump capable of controlling the liquid flow. When the steel structure rises to its highest point, at this time, the stationary disc 51... When the rotating disk 49 and the 3rd component are in a state of mutual contact, the hydraulic pump is started to control the amount of liquid entering the movable chamber 52 of the first component. At this time, the hydraulic pressure causes the piston 57 to move in a specific direction, thereby compressing the helical spring 510. The helical spring 510 generates an elastic force on the movable plate 511 of the second component. At the same time, the stationary disk 513 generates pressure on the rotating disk 49. By controlling this pressure, the friction between the stationary disk 513 and the rotating disk 49 can be controlled. When the pressure is appropriate, the hand crank 48 can be manually rotated to drive the steel structure to rotate at an angle. After the angle rotation is completed, the friction between the stationary disk 513 and the rotating disk 49 is further increased until the steel structure maintains a stable equilibrium state, thereby achieving a controllable angle rotation effect for the steel structure.

[0030] For details regarding the specific structure of the hydraulic braking mechanism 5, please refer to [link / reference]. Figure 4 and Figure 5 The system includes a horizontal hollow body 51 fixedly installed in a fixed base 1. The horizontal hollow body 51 has a first component movable cavity 52 located inside on the side away from the rotating disk 49. The horizontal hollow body 51 also has a liquid flow channel 53 at the end away from the rotating disk 49, connecting the external space and the first component movable cavity 52. ​​The horizontal hollow body 51 has a second component movable cavity 55 located inside on the side closer to the rotating disk 49. The interior of the horizontal hollow body 51 is provided with a connection to the first component movable cavity 52.

[0031] To ensure sufficient room for maneuver during the steel structure's rotation, please refer to [link / reference needed]. Figure 1 , Figure 6 and Figure 7Two threaded height adjustment mechanisms 6 are required. Each mechanism contains a hollow longitudinal body 61 that provides longitudinal support, a rotatable threaded rod 69 installed inside the hollow longitudinal body 61, a drive motor 65 that drives the threaded rod 69 to rotate in a specific direction, a movable threaded sleeve 610 that is fitted around the threaded rod 69 and moves longitudinally when the threaded rod 69 rotates, and a second docking plate 612 fixed to one side of the movable threaded sleeve 610 that moves the arm-shaped support 3. Starting the drive motor 65 causes the threaded rod 69 to rotate, and the movable threaded sleeve 610 causes the arm-shaped support 3 and the electromagnetic housing 44 to move downwards until the bottom of the electromagnetic housing 44 contacts the upper surface of the steel structure. Then, the drive motor 65 is turned off. When the adsorption process is complete, the drive motor 65 is started again, causing the steel structure to move upwards until the limiting slide rod 611 moves to the top of the limiting slide groove 68. Then, the drive motor 65 is turned off, ensuring sufficient space for the steel structure to move during the flipping process.

[0032] For details regarding the specific structure of the threaded height adjustment mechanism 6, please refer to [link / reference needed]. Figure 6 and Figure 7 The system includes a longitudinal hollow body 61 and a movable threaded sleeve 610. The bottom of the longitudinal hollow body 61 is provided with a bottom fixing plate 62, which is integrally structured with and fixedly installed on the upper surface of a bottom mounting base plate 2. The top of the longitudinal hollow body 61 is provided with a top fixing plate 63, which is integrally structured with it. The interior of the longitudinal hollow body 61 is provided with a third component movable cavity 66. An inverted drive motor 65 is fixedly installed at the bottom of the top fixing plate 63 via a motor fixing housing 64. Two symmetrical limiting grooves 68 are provided at the circumferential wall thickness of the longitudinal hollow body 61. A rotatable longitudinal rotating shaft 67 is respectively mounted on each end of the longitudinal hollow body 61 at the two ends located in the third component movable cavity 66 via bearings. A longitudinal threaded rod 69 is fixedly installed between the opposing ends of the moving shaft 67. The top end of the longitudinal rotating shaft 67 at the top is fixedly connected to the bottom end of the rotor of the drive motor 65. The interior of the movable threaded sleeve 610 is provided with an internal threaded hole 613 installed on the body of the longitudinal threaded rod 69 through a threaded structure. The circumferential surface of the movable threaded sleeve 610 is provided with a limiting slide rod 611 integral with it and passing through two limiting slide grooves 68 respectively. A second docking plate 612 is fixedly installed at the end of one of the limiting slide rods 611. The second docking plate 612 is fixedly connected to one end of the arm-shaped bracket 3. When the limiting slide rod 611 moves to the top end of the limiting slide groove 68, the stationary disk 513 and the rotating disk 49 are in a state of mutual abutment.

[0033] When in use, the fixed base 1 and the bottom mounting plate 2 need to be fixedly installed on the ground or workbench according to the corresponding installation position. Connect the liquid flow channel 53 to the liquid circuit of a hydraulic pump that can control the liquid flow. Start the drive motor 65 to make the longitudinal threaded rod 69 rotate and make the moving threaded sleeve 610 drive the arm-shaped bracket 3 and the electromagnetic housing 44 to move downward until the bottom of the electromagnetic housing 44 contacts the upper surface of the steel structure. Then the drive motor 65 can be turned off. Turn on the current controller. According to the electromagnetic principle, the two ends of the electromagnetic iron core 46 will generate magnetism, which will cause the steel structure to be tightly attracted to the bottom of the shaft mounting sleeve 42. Start the drive motor 65 again to make the steel structure move upward until the limit slide rod 611 moves to the top of the limit slide groove 68, and then turn off the drive motor 65. The stationary disk 513 and the rotating disk 49 are in a state of mutual contact. The hydraulic pump is started to control the amount of liquid entering the movable chamber 52 of the first component. At this time, the hydraulic pressure causes the piston 57 to move in a specific direction, thereby compressing the helical spring 510. The helical spring 510 generates an elastic force on the movable plate 511 of the second inner part. At the same time, the stationary disk 513 generates pressure on the rotating disk 49. By controlling this pressure, the friction between the stationary disk 513 and the rotating disk 49 can be controlled. When the pressure is appropriate, the hand crank 48 can be manually rotated to drive the steel structure to rotate at an angle. After the angle rotation is completed, the friction between the stationary disk 513 and the rotating disk 49 is further increased until the steel structure maintains a stable equilibrium state.
