Description

Technical Field

[0001] This utility model relates to the technical field of steel structure positioning equipment, and in particular to a steel structure component flipping device. Background Technology

[0002] With the advancement and development of construction technology, building construction methods are becoming increasingly diversified. Steel structure buildings, as an emerging construction method, are widely used in the construction industry due to their structural stability and fast construction speed. This is especially true for industrial plants with large area and height requirements, which largely utilize steel structure construction. Steel structure flipping and processing has significant meaning and application value in construction engineering and equipment manufacturing. Through flipping and processing, welding, painting, and other treatments can be effectively performed on various surfaces of the steel structure, thereby improving processing efficiency. Simultaneously, the flipping process ensures the uniformity of coatings and welds, improving the overall quality and durability of the structure. Flipping and processing makes it possible to perform precise operations on various parts of the steel structure within a limited space, which is particularly important in the fabrication of large steel structures. During the fabrication process, flipping allows surface treatment and welding operations to be carried out in a safer and more comfortable environment, reducing the risks of manual operation. Flipping and processing can also reduce the required tooling and equipment, lowering production costs.

[0003] Currently, the process of flipping steel structure components is generally done manually. Flipping the workpieces one by one by hand is inefficient. Alternatively, a gantry crane can be used to lift the workpieces and then flip them manually. However, due to the heavy weight and varying shapes and sizes of the workpieces, it is not convenient to position and flip them manually with the help of the gantry crane. This results in low flipping efficiency, poor flipping effect, and high labor intensity. Utility Model Content

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1:

[0033] See Figure 1-4 A steel structure component flipping device includes a support 1, with a vertically mounted suspension rod 2 fixedly installed in the middle of the support 1. The upper end of the suspension rod 2 is fixedly connected to the support 1. Two guide rods 3 are symmetrically arranged on both sides of the lower end of the suspension rod 2. Two guide blocks 4 are symmetrically arranged on the two guide rods 3. The guide rods 3 are rectangular steel pipes. Each guide block 4 is fitted onto the corresponding guide rod 3 through a horizontally arranged rectangular guide hole. Each guide rod 3 is provided with a telescopic rod 5 for driving the guide block 4 to slide along the guide rod 3. The telescopic rod 5 is an electric push rod. The fixed end of the telescopic rod 5 is fixedly connected to the suspension rod 2, and the telescopic end of the telescopic rod 5 is hinged to a fixed part on the guide block 4. The frame is hinged, and two suspension and tilting mechanisms 6 are symmetrically arranged at the bottom of the two guide blocks 4. A horizontal optical shaft 7 is arranged between the two suspension and tilting mechanisms 6. The two ends of the optical shaft 7 are supported and fixed by two supports 31 arranged at the bottom of the two guide rods 3. Two pulleys 71 are arranged on the optical shaft 7, and a horizontal mounting plate 72 is arranged at the bottom of the two pulleys 71. By moving the bracket 1 above the steel structure component 9, the movement is flexible. By lifting the two ends of the steel structure component 9 in sequence and fixing them to the two suspension and tilting mechanisms 6, the steel structure component 9 is driven to rotate to an angle that is easy to process through the two suspension and tilting mechanisms 6. The tilting efficiency is high, saving manual labor intensity and ensuring good safety.

[0034] In this embodiment, see Figure 1 The support frame 1 includes a crossbeam 11, columns 12, reinforcing ribs 13, casters 14, support plates 15, and casters 16. Two columns 12 are vertically fixed at the bottom of both ends of the crossbeam 11. Reinforcing ribs 13 are fixed obliquely between the columns 12 and the crossbeam 11. Casters 14 are installed at the lower end of the column 12 at the front end of the crossbeam 11. A horizontal support plate 15 is installed at the lower end of the column 12 at the rear end of the crossbeam 11. Two casters 16 are fixed at the bottom of both ends of the support plate 15. Both casters 14 and casters 16 are all-steel casters. The two suspension and tilting mechanisms 6 are supported by the casters 14 and casters 16 and can be flexibly moved to the lifting position. The lifting position is flexibly adjustable.

[0035] In this embodiment, see Figure 3Each suspended tilting mechanism 6 includes a U-shaped base 61, a fixed shaft 62, a sprocket 63, a chain 64, a rotating shaft 65, a coupling 66, a motor 67, a brake 68, and a positioning plate 69. A vertically positioned fixed shaft 62 is fixedly installed at the bottom of the guide block 4. The upper end of the fixed shaft 62 is fixedly connected to the guide block 4, and the lower end is fixedly connected to the U-shaped base 61. A rotating shaft 65 is installed inside the U-shaped base 61. Both ends of the rotating shaft 65 are rotatably connected to the bearings in the bearing seats corresponding to the two side plates of the U-shaped base 61. A sprocket 63 is coaxially fixedly installed on the rotating shaft 65, and a chain 64 is installed on the sprocket 63. The upper ends of the sprocket 63 and the chain 64 are chain-driven. The rotating shaft 65 is driven to rotate by the motor 67, which drives the sprocket 63 and the chain 64 to rotate, thereby tilting the steel structure component 9. The tilting efficiency is high and the tilting process is stable.

[0036] In this embodiment, see Figure 3 A positioning plate 69 is fixedly connected to the guide block 4 on one side of the U-shaped seat 61. A motor 67 is installed on the side of the positioning plate 69. The motor 67 is a three-phase asynchronous motor, which is suitable for working conditions that require frequent starting and braking. The output shaft of the motor 67 passes through the positioning plate 69 and is connected to one end of the rotating shaft 65 through the coupling 66. A brake 68 connected to the U-shaped seat 61 is installed on the rotating shaft 65. The brake 68 is an electromagnetic clutch used to fix the rotating shaft 65 and the U-shaped seat 61 as needed. The electromagnetic clutch model is DDL3-O type fast electromagnetic clutch.

[0037] In this embodiment, see Figure 4 An electric hoist 8 is fixedly installed at the bottom of the mounting plate 72. The electric hoist 8 is a commercially available device, model PA1200. The base 81 of the electric hoist 8 is fixedly connected to the mounting plate 72. The electric hoist 8 is manually controlled by the controller to lift the workpiece, which saves time and effort.

[0038] In this embodiment, see Figure 1 , 2 4. The lifting chain 82 of the electric hoist 8 is a circular link chain. The free end of the lifting chain 82 is fixedly connected to the electromagnetic chuck 83. The electromagnetic chuck 83 is a commercially available device with the model number MW5-80L / 2.

[0039] As can be seen from the above technical solution, in use, firstly, the support 1 is moved above the steel structure component 9, so that the steel structure component 9 and the crossbeam 11 of the support 1 are aligned. Then, by pulling the lifting chain 82 of the electric hoist 8, the electric hoist 8 is moved along the optical axis 7 to the front end of the support 1. Then, the controller of the electric hoist 8 controls the electric hoist 8 to release the lifting chain 82, causing the electromagnetic chuck 83 to descend, so that the electromagnetic chuck 83 at the free end of the lifting chain 82 touches the steel structure component 9. Then, the controller controls the electromagnetic chuck 83 to be energized, so that the electromagnetic chuck 83 obtains magnetic attraction. Force is applied to magnetically attract the electromagnetic chuck 83 to the steel structure component 9. Then, the controller controls the electric hoist 8 to wind up the lifting chain 82 until the steel structure component 9 reaches the height where the chain 64 hangs down. Next, the controller controls the telescopic rod 5 at the front end of the bracket 1 to drive the guide block 4 to move along the guide rod 3, so that the suspension and tilting mechanism 6 at the front end of the bracket 1 moves directly above the front end of the steel structure component 9, and the chain 64 is placed on the front end of the steel structure component 9. Then, the power to the electromagnetic chuck 83 on the electric hoist 8 is turned off, releasing the front end of the steel structure component 9. Finally, the electric hoist 8 is moved to the bracket. 1. At the rear end, the controller of the electric hoist 8 controls the electric hoist 8 to release the lifting chain 82, causing the electromagnetic chuck 83 to descend to a lower height, so that the electromagnetic chuck 83 on the free end of the lifting chain 82 contacts the steel structure component 9. Then, the controller controls the electromagnetic chuck 83 to be energized, so that the electromagnetic chuck 83 obtains magnetic attraction, and the electromagnetic chuck 83 is magnetically attracted to the steel structure component 9. Then, the controller controls the electric hoist 8 to rewind the lifting chain 82 until the steel structure component 9 reaches the height where the chain 64 hangs down. Finally, the controller controls the telescopic rod 5 at the rear end of the support 1 to drive the guide block 4. Guided by the guide rod 3, the suspension and flipping mechanism 6 at the rear end of the bracket 1 is moved to directly above the rear end of the steel structure component 9. The chain 64 is then placed on the rear end of the steel structure component 9. The controller then controls the two motors 67 to start rotating clockwise simultaneously. The output shaft of the motor 67 drives the rotating shaft 65 to rotate through the coupling 66. During the rotation of the rotating shaft 65, the sprocket 63 is driven to rotate. The rotation of the sprocket 63 causes the chain 64 to rotate. The rotation of the chain 64 can cause the workpiece to flip clockwise, so that the surface to be processed is facing upwards, keeping it fixed, facilitating processing, reducing processing difficulty, and increasing workpiece processing efficiency.
