Description

Technical Field

[0001] The invention relates to the technical field of steel structure processing, in particular to a turnover mechanism for steel structure processing. Background Art

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

[0003] To this end, the Chinese patent with announcement number "CN218370279U" announced "a turning mechanism for steel structure processing", whose main structure includes a base, support columns are arranged on the left and right sides of the top of the base, a transmission rod is arranged between the two support columns, a transmission roller is arranged on the outside of the transmission rod, and two fixed columns are arranged on the top of the base and are located in front of the transmission roller. Guide rollers are arranged on the opposite sides of the fixed columns on the left and right sides. Two electric hydraulic cylinders are arranged on the top of the base and are located on the front and rear sides of the transmission roller respectively. An adjustment component extending to the inside of the two support columns and movably connected to the inner walls of the two support columns is arranged inside the base, and a control component extending to the opposite sides of the two support columns is arranged on the inner side of the adjustment component. The turning mechanism for steel structure processing, by arranging transmission rollers and guide rollers, the user places the steel structure steel on the transmission roller and is located on the left and right sides. The steel structure is moved to the specified position between the guide rollers on both sides, and then the steel structure is lifted up by starting the electric hydraulic cylinder, and then the electric push rod is started to push the clamping assembly to the upper and lower sides of the steel structure. The user can control the rotating block to drive the bidirectional screw to rotate, and the bidirectional screw drives the two clamping blocks to move to the opposite sides through the two moving plates and clamps and fixes the steel structure. At this time, the double-axis servo motor is started to drive the rotating rod to rotate, and the rotating rod drives the threaded rod to rotate through the active wheel and the driven wheel, and the threaded rod drives the threaded block to move upward, so that the clamping assembly drives the steel structure to move upward to a suitable distance, and then the servo motor is started. The servo motor drives the rotating shaft to rotate through two meshing gears, and the rotating shaft drives the clamping assembly and the steel structure to perform flipping operations through the mounting seat and the electric push rod, thereby effectively helping the user to adjust the flipping operation according to the size of the steel structure and reducing the labor intensity of the staff.

[0004] However, when the above-mentioned flipping mechanism for steel structure processing is actually used, since it utilizes meshing gears to drive the rotating shaft to rotate, the rotating shaft drives the clamping assembly and the steel structure steel to perform flipping operations through the mounting seat and the 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 static state. When the steel structure is processed, the anti-rotation resistance has a relatively poor ability to maintain stability, which can easily cause the steel structure to flip. Therefore, its stability in the working state is relatively poor. Summary of the invention

[0027] To achieve suction fixing effect on steel structure, please refer to Figure 1 , Figure 2 and Figure 3 , it is necessary to set up an electromagnetic fixing mechanism 4, which is internally provided with a horizontal connecting shaft 41 connected to the two arm-shaped brackets 3 through bearings, an electromagnetic coil 45 installed at both ends of the horizontal connecting shaft 41 and capable of passing current, an electromagnetic iron core 46 fixedly installed at the center of the electromagnetic coil 45 and generating a magnetic field after the electromagnetic coil 45 passes current, a hand-cranked wheel 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. The two wiring ends of the electromagnetic coil 45 penetrate the circumferential wall thickness of the electromagnetic shell 44, and when working, the two wiring ends of the electromagnetic coil 45 are respectively connected to the current output end of a current controller that can control the direction and size of the current through a wire. 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, so that the steel structure is tightly adsorbed on the bottom of the shaft mounting sleeve 42, thereby achieving an adsorption-type fixing effect on the steel structure.

[0028] For the specific structure of the electromagnetic fixing mechanism 4, please refer to Figure 2 and Figure 3, including a horizontal connecting shaft 41, wherein the horizontal connecting shaft 41 is provided with a shaft mounting sleeve 42 through bearings on the shaft body near the two ends thereof, and a No. 1 docking plate 43 is fixedly installed on the circumferential surface of the shaft mounting sleeve 42, and an electromagnetic housing 44 is fixedly installed at each end of the horizontal connecting shaft 41, and an electromagnetic coil 45 is fixedly installed at the center of each electromagnetic housing 44, and an electromagnetic iron core 46 is fixedly installed at the center of the electromagnetic coil 45, and an annular buffer pad 47 is installed at the bottom of the electromagnetic housing 44 at the periphery of the electromagnetic iron core 46, and a hand-cranked wheel 48 is fixedly installed on one side of one of the electromagnetic housings 44, and the axis center line of the hand-cranked wheel 48 is in a collinear state with the axis center line of the horizontal connecting shaft 41, and a rotating disk 49 is fixedly installed on one side of the other electromagnetic housing 44, and the axis center line of the rotating disk 49 is in a collinear state with the axis center line of the horizontal connecting shaft 41, and the horizontal height of the bottom surface of the annular buffer pad 47 is lower than the horizontal height of the bottom surface of the electromagnetic housing 44.

When the steel structure rises to the highest point, at this time, the stationary disk 51 3 and the rotating disk 49 are in a state of mutual conflict, the hydraulic pump is started to control the amount of liquid entering the movable chamber 52 of the No. 1 component. At this time, the hydraulic pressure causes the piston body 57 to move in a directional manner, so that the coil spring 510 is compressed, and the coil spring 510 generates an elastic force on the No. 2 inner movable plate 511. At the same time, the stationary disk 513 generates pressure on the rotating disk 49. By controlling the pressure, the friction between the stationary disk 513 and the rotating disk 49 is controlled. When the pressure is appropriate, the hand wheel 48 can be manually rotated to drive the steel structure to flip the angle. When the angle flip 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 an angle-controllable flipping effect on the steel structure.

When the adsorption work is completed, start the driving motor 65 again to move the steel structure upward until the limit slide rod 611 moves to the top of the limit slide groove 68, and then the driving motor 65 can be turned off, so that the steel structure has sufficient space for movement during the flipping process.

[0032] For the specific structure of the threaded height adjustment mechanism 6, please refer to Figure 6 and Figure 7 , including 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 an integral structure with it and fixedly mounted 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 an integral structure with it, the interior of the longitudinal hollow body 61 is provided with a No. 3 component active cavity 66, the bottom of the top fixing plate 63 is fixedly installed with an inverted driving motor 65 through a motor fixing shell 64, the circumferential wall thickness of the longitudinal hollow body 61 is provided with two symmetrical limiting grooves 68, the longitudinal hollow body 61 is provided with a rotatable longitudinal rotating shaft 67 at both ends of the No. 3 component active cavity 66 through bearings, and the two longitudinal rotating shafts 67 are respectively installed with a plurality of movable shafts 67 through bearings. A longitudinal threaded rod 69 is fixedly installed between the opposite ends of the moving shaft 67, and the top end of the longitudinal rotating shaft 67 at the top is fixedly connected to the bottom end of the rotor of the driving motor 65.

The coil spring 510 generates an elastic force on the No. 2 inner movable plate 511. At the same time, the stationary disk 513 generates pressure on the rotating disk 49. By controlling the pressure, the friction between the stationary disk 513 and the rotating disk 49 is controlled.
