Description

Technical Field

[0001] This utility model relates to the field of steel pipe technology, specifically to a synchronous lifting device for steel pipes. Background Technology

[0002] Steel pipes are not only used for transporting fluids and powdery solids, exchanging heat energy, and manufacturing mechanical parts and containers, but they are also an economical steel material. Using steel pipes to manufacture building structural frames, columns, and mechanical supports can reduce weight, save 20-40% of metal, and enable factory-based mechanized construction. Using steel pipes to construct highway bridges not only saves steel and simplifies construction, but also significantly reduces the area requiring protective coatings, saving on investment and maintenance costs.

[0003] Traditional steel pipe bodies are lifted by multiple points of power, which cannot achieve a completely synchronous lifting effect in practical applications. At the same time, due to the lack of clamping devices, the steel pipe body is prone to slipping off the device when being lifted, affecting the stability of the steel pipe body during lifting.

[0004] Therefore, a steel pipe synchronous lifting device is proposed to solve the problems mentioned above. Utility Model Content

[0025] Please see Figure 1 - Figure 4 This embodiment of a steel pipe synchronous lifting device includes a base 1. A support block is fixedly installed on the upper end face of the base 1. A first servo motor 2 is fixedly installed on the upper end face of the support block. A first bidirectional threaded rod 3 is fixedly installed at the output end of the first servo motor 2. A moving block 5 is threadedly connected to the surface of the first bidirectional threaded rod 3. Fixed rods 7 are fixedly installed on both the front and rear sides of the moving block 5. A first movable plate 9 and a second movable plate 10 are rotatably sleeved on the surface of the fixed rod 7. A worktable 11 is rotatably installed at the end of the second movable plate 10. A support frame 12 is fixedly installed on the upper end face of the worktable 11. A support plate 14 is fixedly installed on the front of the support frame 12. A second servo motor 15 is fixedly installed on the upper end face of the support plate 14. A second bidirectional threaded rod 16 is fixedly installed through the inner wall of the support frame 12 at the output end of the second servo motor 15. Multiple limiting plates 18 are threadedly sleeved on the surface of the second bidirectional threaded rod 16. Protective pads 20 are fixedly installed on the inner walls of the multiple limiting plates 18. The inner walls of the protective pads 20 abut against the steel pipe body 21.

[0026] When the second servo motor 15 controls the second bidirectional threaded rod 16 to rotate clockwise, the second bidirectional threaded rod 16 can control multiple limiting plates 18 to move simultaneously toward the steel pipe body 21, and make the inner wall of the protective pad 20 abut against the surface of the steel pipe body 21 for clamping, thus completing the limiting of the steel pipe body 21. When the first servo motor 2 controls the first bidirectional threaded rod 3 to rotate, it can control the relative movement of the moving block 5, thus completing the lifting of the steel pipe body 21.

[0027] Among them, multiple baffles 17 are fixedly installed on the surface of the second bidirectional threaded rod 16, and multiple second bidirectional threaded rods 16 are provided. The end of the second bidirectional threaded rod 16 away from the first servo motor 2 is rotatably sleeved in the support frame 12.

[0028] By setting baffle 17, the segmented design of multiple second bidirectional threaded rods 16 is realized, which facilitates the transmission of the limiting plate 18.

[0029] The inner wall of the limiting plate 18 is provided with a second threaded hole 19, which matches the surface of the second bidirectional threaded rod 16.

[0030] The surface of the second movable plate 10 is movably overlapped with one side of the first movable plate 9, and the first movable plate 9 is rotatably installed inside the support frame 12.

[0031] The inner wall of the movable block 5 is provided with a first threaded hole 6, and the inner wall of the first threaded hole 6 matches the inner wall of the first bidirectional threaded rod 3.

[0032] Among them, multiple limiting plates 8 are fixedly installed on the surface of the fixed rod 7, and one side of each limiting plate 8 overlaps with the surface of the first movable plate 9 and the second movable plate 10.

[0033] By setting the limiting piece 8, the first movable plate 9 and the second movable plate 10 can overlap, improving the aesthetics;

[0034] The lower end face of the support frame 12 is fixedly installed at the center of the upper end face of the workbench 11. The surface of the limiting plate 18 slides within the support frame 12. A connecting plate 4 is fixedly installed on the upper end face of the support frame 12. The end of the first bidirectional threaded rod 3 that is away from the first servo motor 2 is rotatably sleeved within the connecting plate 4.

[0035] The working principle of the above embodiments is as follows:

[0036] When clamping the steel pipe body 21 during use, firstly, place the steel pipe body 21 horizontally on the support frame 12 of the protective pad 20, and position it on one side of the two limiting plates 18. After this, connect the power supply to the second servo motor 15, causing the second servo motor 15 to drive the second bidirectional threaded rod 16 to rotate, thereby controlling the limiting plates 18 to move towards the steel pipe body 21. When the inner wall of the protective pad 20 abuts against the surface of the steel pipe body 21, the clamping and limiting of the steel pipe body 21 is completed, ensuring the stability of the steel pipe body 21 during placement. The second bidirectional threaded rod 16 in this device... By segmenting the design, different sets of limit plates 18 can be driven to move inward and outward simultaneously. When the steel pipe body 21 needs to be lifted, the power supply to the first servo motor 2 is connected, so that the first servo motor 2 controls the first bidirectional threaded rod 3 to rotate clockwise. The first bidirectional threaded rod 3 controls the moving block 5 to move towards the center by means of the threaded connection between the first bidirectional threaded rod 3 and the moving block 5. The first movable plate 9 and the second movable plate 10 are pulled by the fixed rod 7, so that the first movable plate 9 and the second movable plate 10 are changed from the inclined state to the vertical state, thereby changing the height of the worktable 11 and lifting the steel pipe body 21.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
