Description

Technical Field

[0001] This utility model relates to the field of steel handling technology, and in particular to a steel handling device for constructing a large-area complex factory frame structure. Background Technology

[0002] With the rapid development of industry, ultra-large and complex factory buildings are increasingly widely used in manufacturing, warehousing and logistics due to their advantages such as high space utilization and strong functionality. The construction of the framework structure of such factory buildings usually requires a large amount of steel of different specifications and shapes, such as large H-beams and ultra-long steel beams, resulting in a huge amount of steel handling work and a heavy workload.

[0003] Traditional clamping mechanisms are mostly fixed in shape or have a simple opening and closing design. They are difficult to accurately fit steel materials of various shapes (such as irregularly shaped steel and bent steel) in large and complex factory buildings. For some special T-shaped steel and Z-shaped steel, traditional clamps have difficulty finding a suitable point of force, resulting in unstable clamping. The size of steel materials used in factory construction varies greatly, ranging from small angle steel to large and extra-long steel beams. Traditional clamping mechanisms have a limited adjustment range and cannot effectively clamp steel materials that exceed their preset size range.

[0004] In the construction of large-scale and complex factory structures, traditional hydraulic lifting and rotating technologies for steel handling devices have significant shortcomings. Regarding lifting, stability is poor, hydraulic devices are prone to damage, and they cannot adapt to varying steel weights. Regarding rotation, the mechanism lacks flexibility, is limited in confined spaces, has low positioning accuracy, and struggles to accurately place materials. Furthermore, its coordination with lifting and other actions is poor, affecting overall handling efficiency and safety, and ultimately failing to meet the needs of factory construction.

[0032] Reference Figure 1-3 This utility model provides an embodiment of a steel handling device for constructing a large-area complex factory frame structure. The device includes a base 1, with tracks 2 on both sides. The tracks 2 offer strong terrain adaptability, excellent stability, flexible and convenient steering, and protection of the construction site. A rotating platform 4 is rotatably connected to the top of the base 1. A support platform 3 is fixedly connected to the top of the rotating platform 4. A support frame 5 is fixedly connected to the top of the support platform 3. A first hydraulic cylinder 6 is fixedly connected to the bottom of the support frame 5. A first fixing block 7 is fixedly connected to the output end of the first hydraulic cylinder 6. A second hydraulic cylinder 13 is fixedly connected to the bottom center of the first fixing block 7. A sliding groove 24 is provided on one side of the support frame 5. A counterweight box 23 is slidably connected inside the sliding groove 24. Different sizes of counterweight blocks can be placed inside the counterweight box 23. By increasing or decreasing the number of counterweight blocks, the overall weight of the counterweight box 23 can be flexibly adjusted to meet the handling needs of steel of different weights.

[0033] A first fixing block 7 is connected to a first fixing post 8 through one end and fixedly connected to another fixing post 30 through one end and fixedly connected to the other end. A first clamping block 9 is connected to both ends of the outer ring of the first fixing post 8 through and rotatably connected to the first clamping block 9. A first rotating block 10 is rotatably connected to one side of the first clamping block 9. A second clamping block 15 is connected to both ends of the outer ring of the second fixing post 30 through and rotatably connected to the second clamping post 30. A third rotating block 14 is rotatably connected to one side of the second clamping block 15. A second rotating block 11 is rotatably connected to one side of the first rotating block 10, and the second rotating block 11 is rotatably connected to the third rotating block 14. A second fixing block 12 is fixedly connected between the second rotating blocks 11. The output end of the second hydraulic cylinder 13 is fixedly connected to the top of the second fixing block 12. The linkage structure composed of multiple rotating connecting parts enables the first clamping block 9 and the second clamping block 15 to adaptively adjust according to the shape and contour of the steel when clamping it. Even if the steel is irregularly shaped, the clamping block can fit tightly against the surface of the steel. The top two ends of the second fixing block 12 are fixedly connected to the first motor 19, and the output ends of the first motor 19 are fixedly connected to the winding wheel 18. The output ends of the two first motors 19 are in opposite directions. The top one side of the second fixing block 12 is slidably connected to the loop rope 16, and one end of the loop rope 16 is fixedly connected to the winding wheel 18. When the winding wheel 18 rotates, it tightens the loop rope 16 and loosens it when it rotates in the opposite direction. The combination of the loop rope 16 and the winding wheel 18 provides additional fixation for the clamped steel. For steel with special shapes that are difficult to clamp stably, or steel that may loosen due to vibration or other factors during handling, the tightening of the rope 16 can further constrain the steel from the outside. Tightening collars 17 are fixedly connected to both ends of the bottom of the second fixing block 12. One side of the bottom of the tightening collar 17 is fixedly connected to one end of the rope 16, and the other end of the rope 16 passes through and slides through the tightening collar 17 and the second fixing block 12. The addition of the tightening collar 17 changes the way the rope 16 is subjected to force, allowing the rope 16 to form more concentrated pressure at the tightening collar 17 during tightening. Compared to relying solely on the winding wheel 18 for winding, this provides a stronger binding force on the steel, effectively preventing the steel from loosening due to vibration during handling. Factors such as movement and shaking cause the rope 16 to loosen. A fixed frame 21 is fixedly connected to one side of the top of the support frame 5, and a fixed frame 21 is fixedly connected to the top of one side of the support frame 5. Both ends of the fixed frame 21 are rotatably connected to pulleys 22. Both ends of the top of the first fixed block 7 are fixedly connected to steel wire ropes 20. The steel wire ropes 20 are slidably connected to the pulleys 22, and one end of the steel wire ropes 20 is fixedly connected to the top of the counterweight box 23. The addition of pulleys 22 reduces the friction and wear of the steel wire ropes 20 during transmission, enabling the steel wire ropes 20 to transmit the weight of the counterweight box 23 more stably. In the handling of steel in large-area complex factory buildings, the counterweight balance hydraulic lifting device significantly improves performance through the cooperation of the counterweight box 23 and the clamping mechanism.During ascent, the weight of the counterweight box 23, via the wire rope 20 and pulley system, creates a reverse pulling force, offsetting part of the load. For example, when moving 10 tons of steel with a 6-ton counterweight box 23, the load on the hydraulic system can be reduced by 60%, lowering energy consumption and component wear. During descent, the rising counterweight box 23 generates a pulling buffer, preventing the platform from swaying and becoming uncontrollable, thus ensuring the safety of steel handling. In addition, it is crucial to set the weight of the counterweight box appropriately. After a batch of steel of the same weight is moved, the weight of the counterweight box 23 needs to be changed before moving the next batch. A third fixing block 25 is fixedly connected to both sides of the top of the base 1. A second motor 27 is fixedly connected to one side of the top of the base 1. A worm gear 26 is fixedly connected to the output end of the second motor 27, and one end of the worm gear 26 passes through and is rotatably connected to the third fixing block 25. A worm wheel 28 is fixedly connected to the outer ring of the rotating table 4. The worm wheel 28 and the worm gear 26 are meshed. A protective cover 29 is fixedly connected to the top of the base 1. The protective cover 29 plays a protective role. It can prevent dust, debris and other objects from entering the transmission mechanism of the worm wheel 28 and worm gear 26, avoiding wear and damage to the transmission components. At the same time, it can also prevent operators from accidentally touching the rotating parts and ensure operational safety.

[0034] Working principle: First, the device moves via the tracks 2 on both sides of the base 1. Then, the second hydraulic cylinder 13 is activated, and its output end extends and retracts to move the second fixed block 12. The second fixed block 12 drives the first clamping block 9 and the second clamping block 15 to rotate around the first fixed column 8 and the second fixed column 30 respectively through the second rotating block 11, the first rotating block 10, and the third rotating block 14, thereby clamping and releasing the steel. The linkage structure composed of multiple rotating connecting parts allows the clamping blocks to adaptively adjust according to the shape of the steel, closely fitting the surface of irregularly shaped steel. The output ends of the first motors 19 at both ends of the top of the second fixed block 12 are connected to the winding reels 18, and the output ends of the two first motors 19 are in opposite directions. One end of the rope 16 is fixed to the winding reel 18, and the other end passes through the top side of the second fixed block 12, the bottom side of the tightening ring 17, and then through the tightening ring 17 and the second fixed block 12 in the opposite direction. The first motor 19 is started, driving the winding reel 18 to rotate and wind the rope 16, tightening the loop 17 to create concentrated pressure on the rope 16, generating a stronger binding force on the steel and further constraining it from the outside. Conversely, the rope 16 is released in the opposite direction, releasing the binding. Then, the first hydraulic cylinder 6 is activated, and its output end extends and retracts, driving the first fixed block 7 and the clamping mechanism below to rise and fall, realizing the upward and downward transport of the steel. During this process, the counterweight box 23 slides along the groove 24 on one side of the support frame 5. When rising, the counterweight box 23 descends due to gravity, and its weight is transmitted to the first fixed block 7 through the steel wire rope 20 connected to the top of the first fixed block 7, and then through the pulleys 22 at both ends of the fixed frame 21, forming a reverse pulling force to offset part of the weight of the steel and the clamping mechanism, reducing the load on the hydraulic system. When descending, the counterweight box 23 rises, generating a pulling force to slow the descent, assisting the hydraulic system in controlling the descent process and preventing platform swaying or loss of control. By increasing or decreasing the number of counterweights of different specifications within the counterweight box 23, the overall weight can be flexibly adjusted to accommodate the handling of steel of varying weights. When the handling angle needs to be adjusted, the second motor 27 is activated. The second motor 27 drives the worm gear 26 to rotate, and the worm gear 26 meshes with the worm wheel 28 on the outer ring of the rotating platform 4, driving the rotating platform 4 to rotate, thereby adjusting the angle of the support platform 3 and the components above it. The third fixing block 25 supports and positions the worm gear 26, ensuring its stable rotation. The protective cover 29 on the top of the base 1 prevents dust and debris from entering the worm wheel 28 and worm gear 26 transmission mechanism, avoiding wear and damage to components, while also ensuring the safety of operators.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
