Description

Technical Field

[0001] The present application relates to the technical field of steel structure component hoisting, and in particular to a steel structure plant component hoisting device. Background Art

[0002] The lifting of steel structure workshop components is a critical construction link in the process of steel structure workshop construction. The main process is to use a variety of lifting equipment to accurately lift the steel structure workshop components that have been processed and manufactured in advance in the factory, such as steel columns, steel beams, roof trusses and purlins, to the designated location according to the design requirements, and then complete the installation and fixing work;

[0003] The Chinese patent with the announcement number "CN220618099U" discloses a lifting device for an H-shaped steel member, which is provided with an end fixing mechanism for fixing the two ends of the H-shaped steel, and is matched with a first auxiliary fixing mechanism to adjust and assist in fixing the two ends of the H-shaped steel. In addition, the auxiliary lifting mechanism and the lifting mechanism work together to lift the first auxiliary fixing mechanism and the middle fixing mechanism, and the middle fixing mechanism is responsible for fixing the middle part of the H-shaped steel. The second auxiliary fixing mechanism assists the middle fixing mechanism to further stabilize the H-shaped steel.

[0004] However, there are some problems in the actual application of this device. Although an end fixing mechanism is set to assist in fixation, in actual use, the lifting rope connected to the end fixing structure cannot be reeled in and adjusted. This makes it difficult to flexibly adjust to meet the needs when facing steel structure components of different lengths. Moreover, during the operation of the device, the end fixing mechanisms at both ends lack further limiting structures. During the lifting operation, the H-shaped steel components are prone to slipping.

[0018] 1.

[0019] 2. This device works in coordination with the side limit mechanism through the winding assembly of the sling. During use, the second motor can be started to drive the second synchronous wheel to make the second winding roller rotate synchronously, wind up the auxiliary lifting rope, and move the side limit group inward. It is suitable for short components. If a long component is hoisted, the second motor runs in reverse, the second synchronous wheel reverses, the second winding roller loosens the rope, and the spacing of the side limit groups is extended. By adjusting the spacing of the side limit groups and combining with the middle limit group, the two ends and the middle of the clamped component can be stably clamped. After clamping is completed, the first motor is started, and the first motor drives the first synchronous wheel, which is driven by the first synchronous belt to drive the first winding roller to wind up the main lifting rope. Under the guidance of the guide roller, the component is lifted steadily, and efficient lifting of components of different lengths is achieved, and the operation is simple.

[0020] 3. When the device clamps the steel structure member, the side limit group and the middle limit group cooperate to start the third motor first to drive the bidirectional screw to rotate. Because the threads at both ends of the screw rotate in opposite directions, the two movable blocks are synchronously driven to move back and forth, driving the L-shaped clamping arm to assist in clamping the middle of the member. After clamping, start the second motor to reel in the auxiliary lifting rope, so that the side limit group moves to both sides of the member, twist the adjusting handle to rotate the one-way screw, drive the slide bar to slide in the side rail, drive the side clamping plate to move up, and cooperate with the upper clamping plate to clamp the two ends of the member. When reeling, the toggle plate is squeezed to rotate the shaft and compress the torsion spring. The L-shaped limit arm is parallel to the two ends of the member to prevent the member from loosening. The whole has good stability and avoids the steel structure member from falling off.

[0021] 4. To ensure stable clamping, this device twists the limit screw to insert the limit hole, fix the adjustment handle, limit the one-way screw, make the slide bar stable, and when loosening the component, first start the second motor to run in reverse, loosen the auxiliary lifting rope, untie the limit screw, move the side clamp down, remove the side limit group, reset the torsion spring to make the L-shaped limit arm rotate outward, and then start the third motor in reverse, driving the two-way screw to drive the clamping arm to move outward. This series of designs realizes the rapid disassembly and assembly of steel structure components, and can firmly cover the two ends and the middle part of the fixed component when clamping, so as to fully guarantee the stability and safety of lifting.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-8 This application is described in further detail.

[0032] The present application discloses a steel structure factory building component hoisting device. Figure 1-8 As shown, it comprises a base 1, a load-bearing mechanism 2 is fixedly installed on one side of the top of the base 1, a frame 3 is fixedly installed on one side of the top of the base 1 away from the load-bearing mechanism 2, a suspension mechanism 5 is movably installed inside the frame 3, and a sling 6 is provided at the outer end of the suspension mechanism 5;

[0033] The sling 6 includes a main hoisting rope 61, the outer end of the main hoisting rope 61 is connected to the suspension mechanism 5, a main frame 62 is fixedly installed at the bottom of the main hoisting rope 61, a winding assembly 63 is installed at the upper end of the main frame 62, side limit groups 64 are installed at both ends of the outer side of the winding assembly 63, a middle limit group 65 is installed at the bottom of the main frame 62, and the inner side brackets of the side limit group 64 and the middle limit group 65 clamp the steel structure member 4. Before lifting, the device can add or reduce the load on one side of the top of the base 1 through the load-bearing mechanism 2 according to the weight of the steel structure member 4, adjust the overall center of gravity, and ensure stable lifting. During lifting, the suspension mechanism 5 is started, which cooperates with the frame 3 and uses an electric push rod The extension and retraction of 55 is linked by the upper hinge seat 53 and the lower hinge seat 54, driving the main shaft 51 in the frame 3 to rotate, so that the hydraulic telescopic boom 52 can rotate and adjust the tilt angle. At the same time, the hydraulic telescopic boom 52 can extend and retract itself, so as to flexibly change the height and position of the sling 6 and move the sling 6 above the component. Then, the winding component 63 operates through the suspension mechanism 5 to wind or release the auxiliary lifting rope 634 according to the length of the component, adjust the distance between the two side limit groups 64, cooperate with the middle limit group 65, and stably clamp the steel structure component 4 from both ends and the middle. Finally, the winding component 63 is started again to drive the main lifting rope 61 to wind up, and under the guidance of the guide roller 566, the component is stably lifted to complete the lifting.

[0034] Please refer to Figure 5-Figure 8The winding assembly 63 includes a side frame 631 and a fixed arm 632. The side frame 631 is fixedly installed on the upper ends of both sides of the main frame 62, and the fixed arm 632 is fixedly installed on the middle part of the upper front end of the main frame 62. The inside of the side frame 631 is rotatably connected to the second winding roller 633. The outer surface of the second winding roller 633 is wound with a secondary suspension rope 634. The outer end of the secondary suspension rope 634 is connected to the side limit group 64. A second motor 635 is fixedly installed on the front of the fixed arm 632. The outer ends of the front sides of the side frames 631 are rotatably connected to the second synchronous wheels 636. The rear side of the second synchronous wheels 636 is connected to the front end of the second winding roller 633. The second synchronous wheels 636 are connected through a second synchronous belt 637 for transmission. The output end of the second motor 635 and a second synchronous The step wheel 636 is fixedly connected at the front, and the side limit group 64 includes a side rail 641, which is fixedly installed on the outer end of the auxiliary suspension rope 634. The inner rotation of the side rail 641 is connected with a one-way screw rod 642, and the outer surface of the one-way screw rod 642 is threadedly connected with a slide rod 643. The bottom of the slide rod 643 is fixedly installed with a side clamping plate 644, and the top of the side clamping plate 644 is fitted and connected with the bottom of the steel structure member 4. The inner upper end of the side rail 641 is fixedly connected with an upper clamping plate 648, and the bottom of the upper clamping plate 648 is fitted and connected with the top of the steel structure member 4. The top of the one-way screw rod 642 passes through the side rail 641 and is fixedly installed with an adjustment handle 649. Baffle assemblies 645 are provided on both sides of the side rail 641. The top of the side rail 641 is evenly spaced and arranged in a ring to open a limit position The limiting screw 647 is threadedly connected to one side of the adjusting handle 649, and the bottom of the limiting screw 647 passes through the adjusting handle 649 and is inserted into a limiting hole 646. The limiting screw 647 is set as a hand-tightened screw. By starting the second motor 635, the output end of the motor drives the second synchronous wheel 636 connected thereto to rotate. Since the second synchronous wheels 636 are connected through the second synchronous belt 637, the second synchronous wheel 636 on the other side is driven to rotate synchronously. The two second synchronous wheels 636 respectively drive the second winding roller 633 in the side frame 631 to rotate. When the second winding roller 633 rotates, the auxiliary lifting rope 634 wound around the outer surface begins to be wound or unwound. When it is necessary to clamp the steel structure member 4, if the winding auxiliary lifting rope The side rail 641 connected to the outer end of the rope 634 will approach the component. At this time, the adjusting handle 649 is twisted, and the adjusting handle 649 drives the one-way screw rod 642 to rotate. Since the one-way screw rod 642 is threadedly connected to the sliding rod 643, the sliding rod 643 will move up and down along the screw rod inside the side rail 641, and the side clamping plate 644 at the bottom of the sliding rod 643 will move accordingly. When the side clamping plate 644 moves up to fit the bottom of the steel structure component 4, it cooperates with the upper clamping plate 648 fixedly connected to the top, so that the steel structure component 4 can be clamped from both sides. After the adjustment is completed, the limit screw 647 is screwed into one side of the adjusting handle 649 and inserted into the limit hole 646 to fix the adjusting handle 649 to prevent the one-way screw rod 642 from rotating and ensure that the side clamping plate 644 is stably clamped. If the component needs to be loosened,The reverse operation is sufficient, and the baffle assemblies 645 on both sides of the side rails 641 play a protective and auxiliary positioning role.

[0035] Please refer to Figure 1-Figure 4 The suspension mechanism 5 includes a main shaft 51, which is rotatably connected to the upper end of the frame 3. A hydraulic telescopic boom 52 is fixedly installed in the middle of the main shaft 51. An upper hinge seat 53 is fixedly installed on the lower end of the hydraulic telescopic boom 52 near the base 1. A lower hinge seat 54 is fixedly installed inside the frame 3. An electric push rod 55 is hinged between the inner sides of the upper hinge seat 53 and the lower hinge seat 54. A power group 56 is fixedly installed on the outer end of the hydraulic telescopic boom 52. The power group 56 includes a suspension frame 561. The suspension frame 561 is fixedly installed on the outer end of the hydraulic telescopic boom 52. A first motor 562 is fixedly installed at one end of the suspension frame 561 near the hydraulic telescopic boom 52. The output end of the first motor 562 passes through the suspension frame 561 and is fixedly installed with a first synchronous wheel 563. The middle part of the suspension frame 561 is rotatably connected to a first winding roller 564. The upper end of the main suspension rope 61 is wound on the outer surface of the first winding roller 564. The middle part of the rear side of the suspension frame 561 is also rotatably connected to the first synchronous wheel 563. The first synchronous wheels 563 are connected by a first synchronous belt 565. The inner side of the suspension frame 561 is away from the hydraulic telescopic boom 5 2 is rotatably connected to a guide roller 566, and the main hoisting rope 61 is transmission-connected to the guide roller 566. By starting the electric push rod 55, its telescopic action will cause an angle change between the upper hinge seat 53 and the lower hinge seat 54. Since the upper hinge seat 53 is fixed to the lower end of the hydraulic telescopic boom 52, and the lower hinge seat 54 is fixed inside the frame 3, this angle change drives the main shaft 51 to rotate inside the frame 3, thereby adjusting the inclination angle of the hydraulic telescopic boom 52. At the same time, the hydraulic telescopic boom 52 itself can be telescoped according to actual lifting needs, so as to flexibly change the lifting height. and position. When it is necessary to lift the steel structure component 4, start the first motor 562. The output end of the first motor 562 drives the first synchronous wheel 563 to rotate. Through the first synchronous belt 565, the first synchronous wheel 563 on the rear side of the suspension frame 561 is driven to rotate synchronously, and then the first winding roller 564 is driven to rotate, so as to reel in or unreel the main lifting rope 61 wound on its outer surface. During the winding or unreeling process, the main lifting rope 61 will be stably connected to the sling 6 under the guidance of the guide roller 566, thereby realizing the smooth lifting and lowering of the steel structure component 4.

[0036] Please refer to Figure 7-Figure 8The baffle assembly 645 includes a square groove 6451, which is opened in the middle of both sides of the guide rail. The top and bottom of the square groove 6451 are provided with circular grooves 6452. The inner sides of the circular grooves 6452 are fixedly installed with torsion springs 6453. The inner ends of the torsion springs 6453 are fixedly installed with shafts 6454. The two ends of the shafts 6454 are rotatably connected to the inside of the circular grooves 6452. The outer surface of the shaft 6454 is fixedly installed with L-shaped limit arms 6455. The inner side of the outer surface of the shaft 6454 is fixedly installed with a toggle plate 6456. The inner side of the toggle plate 6456 is fitted and connected to both sides of the steel structure member 4. The middle limit group 65 includes a bottom rail 651, which is fixedly installed in the middle of the bottom of the main frame 62. One end of the bottom rail 651 is fixed A third motor 652 is fixedly installed, and the output end of the third motor 652 passes through the bottom rail 651 and is fixedly installed with a bidirectional screw rod 653. The threads at both ends of the bidirectional screw rod 653 rotate in opposite directions. Both ends of the bidirectional screw rod 653 are threadedly connected with a movable block 654. A clamping arm 655 is fixedly installed at the bottom of the movable block 654. The clamping arm 655 is also L-shaped and the inner side is closely connected to the steel structure member 4. By arranging a baffle assembly 645, when the side rail 641 approaches the steel structure member 4 driven by the auxiliary suspension rope 634, the two sides of the member will gradually fit the toggle plate 6456. As it continues to approach, the toggle plate 6456 is squeezed, driving the rotating shaft 6454 to rotate in the circular groove 6452, and the torsion spring 6453 in the circular groove 6452 is compressed. Since the rotating shaft 6454 is connected to the L-shaped limiting arm, the rotation of the rotating shaft 6454 causes the L-shaped limiting arm to rotate accordingly. When the component is firmly clamped, the L-shaped limiting arm is parallel to the two sides of the component, which plays a limiting role in preventing the component from loosening. Looking at the limiting group 65 again, the third motor 652 is started, and the output end of the motor drives the bidirectional screw 653 to rotate. Because the threads at both ends of the bidirectional screw 653 rotate in opposite directions, the movable block 654 connected by the threads at both ends will make a reverse relative movement or move away from each other during rotation. The L-shaped clamping arm 655 fixed at the bottom of the movable block 654 moves with the movable block 654. When the movable block 654 moves relatively, the clamping arm 655 moves inward to firmly clamp the middle part of the steel structure component 4; when the component needs to be loosened, the third motor 652 is reversed, the movable block 654 moves away from each other, and the clamping arm 655 moves outward to loosen the steel structure component 4.

[0037] Please refer to Figure 1-Figure 4The load-bearing mechanism 2 includes a base plate 21, which is fixedly mounted on the top of the base 1 on one side away from the suspension mechanism 5. Limit rods 22 are fixedly mounted on both sides of the top of the base plate 21. The outer surface of the limit rod 22 is slidably connected with a load plate 23. The load-bearing mechanism 2 is mainly used to adjust the center of gravity of the hoisting device to ensure the stability of the hoisting process. Before the actual operation, the load-bearing mechanism 2 can be adjusted according to the weight and size of the steel structure member 4 to be hoisted and the specific working conditions of the hoisting. Since the base plate 21 is fixed on the top of the base 1 on one side away from the suspension mechanism 5, by adjusting the weight plate 23 on both sides of the top of the base plate 21 Different numbers of weight plates 23 are slidably placed on the outer surface of the limit rod 22, which can change the weight of that side of the base 1. When hoisting heavier steel structure components 4, or in a complex hoisting environment, increasing the number of weight plates 23 can cause the center of gravity of the base 1 to shift to the side of the weight-bearing mechanism 2 to prevent the hoisting device from tilting or even overturning due to unstable center of gravity; conversely, if the component is lighter, reduce the number of weight plates 23 to maintain the overall balance. The limit rod 22 plays a guiding and limiting role to ensure that the weight plates 23 are stably placed and will not move at will, thereby ensuring the safety and stability of the entire hoisting process.

[0038] The implementation principle of a steel structure factory building component hoisting device in the embodiment of the present application is as follows: the device combines the suspension mechanism 5 with the load-bearing mechanism 2, which greatly optimizes the hoisting process of the steel structure component 4. In actual operation, the sling 6 is first used to assist in hoisting the steel structure component 4. After the component is hoisted into place, the electric push rod 55 is started. The electric push rod 55 pushes the main shaft 51 inside the frame 3 to rotate through telescopic movement with the help of the auxiliary articulation linkage of the upper articulated seat and the lower articulated seat. The rotation of the main shaft 51 drives the hydraulic telescopic boom 52 to rotate, thereby realizing precise adjustment of the inclination angle of the boom. This adjustment can not only flexibly change the total hoisting height of the sling 6, but also accurately adjust the hoisting position. In addition, the hydraulic telescopic boom 52 itself has a telescopic function, and cooperates with the electric push rod 55 to push the further telescopic adjustment after the boom rotates, which significantly improves the adaptability of the sling 6 crane, so that it can easily cope with various complex hoisting conditions.

[0039] During the hoisting process, the device also fully considers the influence of the weight of different components on the hoisting stability. By arranging different numbers of weight plates 23 on the outer surface of the limit rod 22 on the base plate 21, the weight on the other side of the top of the base 1 can be flexibly adjusted to ensure that the weight distribution on the top of the base 1 is always in a stable state. This design enables the device to achieve efficient position adjustment when hoisting the steel structure component 4 of the factory building, and also has excellent stability, providing a strong guarantee for safe and accurate hoisting operations.

[0040] By setting a sling 6, the device can achieve efficient lifting of steel structure members 4 of different lengths through the cooperation of the winding assembly 63 and the side limit mechanism during use. When the second motor 635 is started, the motor drives the second synchronous wheel 636 to rotate, and then synchronously drives the second winding rollers 633 inside the two side frames 631 to rotate. The synchronous rotation of the two second winding rollers 633 can simultaneously reel in the two auxiliary lifting ropes 634, so that the two side limit groups 64 move inward, so as to adapt to the shorter steel structure member 4. When it is necessary to lift a longer steel structure member 4, it is only necessary to start the second motor 635 to run in reverse, and the second synchronous wheel 636 will rotate in reverse accordingly, and the second winding roller 633 will loosen the auxiliary lifting rope 634, extending the distance between the two side limit groups 64. Through this flexible way of loosening the auxiliary lifting rope 634, the distance between the two side limit groups 64 can be accurately adjusted, and the middle limit group 65 can be cooperated to achieve stable clamping and positioning of the two ends and the middle of the steel structure member 4, thereby ensuring the stability of the lifting process.

[0041] After the steel structure component 4 is clamped, the first motor 562 is started, and the motor drives the first synchronous wheel 563 to rotate. The two first synchronous wheels 563 are driven by the first synchronous belt 565 to drive the first winding roller 564 to rotate, and then the main hoisting rope 61 is wound. Under the support and guidance of the guide roller 566, the steel structure component 4 clamped by the hoisting device 6 can be lifted steadily. The whole process is simple and efficient to operate, which fully demonstrates the good adaptability of the device in the hoisting operation of the steel structure component 4.

[0042] In the clamping link of the steel structure member 4, the device realizes the stable clamping and rapid disassembly and assembly of the member through the coordinated work of the side limit group 64 and the middle limit group 65. In the clamping process, the third motor 652 is first started, and the motor drives the bidirectional screw 653 to rotate. Since the threads at both ends of the bidirectional screw 653 rotate in opposite directions, the two movable blocks 654 can be synchronously driven to move back and forth during rotation. The sliding of the movable block 654 drives the L-shaped clamping arm 655 at the bottom thereof to move back and forth, thereby auxiliary clamping of the steel structure member 4. The unique design of the L-shaped clamping arm 655 enables it to tightly cover the steel structure member 4, thereby realizing stable clamping of the middle part of the member.

[0043] After the clamping is completed, the second motor 635 is started to drive the second winding roller 633 to wind up the auxiliary lifting rope 634, so that the two side limit groups 64 move to the two sides of the steel structure member 4. At this time, the adjusting handle 649 is twisted to drive the one-way screw rod 642 to rotate, driving the sliding rod 643 to slide in the side rail 641, and then driving the side clamping plate 644 to move up, so that it can be stably fitted to the bottom of the steel structure member 4. The upper clamping plate 648 cooperates with the side clamping plate 644 to achieve a stable clamping of the two ends of the required hanging steel structure member 4. During the winding process of the lifting rope 634, the toggle plate 6456 on the inner side of the side rail 641 contacts the two ends of the steel structure member 4. As the auxiliary lifting rope 634 continues to be wound, the two ends of the member further squeeze the toggle plate 6456, so that the toggle plate 6456 drives the rotating shaft 6454 to rotate, squeezing the torsion spring 6453 to put it in a compressed state. At this time, the L-shaped limiting arm 6455 on the outer side of the rotating shaft 6454 is parallel to the two ends of the steel structure member 4, which plays a limiting role on the member, effectively preventing the steel structure member 4 from loosening during the lifting process;

[0044] To ensure the stability of clamping, during the adjustment process, the limiting screw 647 can be twisted to insert the limiting hole 646 to fix the adjusting handle 649, thereby limiting the one-way screw rod 642 and keeping the sliding rod 643 in a stable state. When it is necessary to loosen and untie the steel structure component 4, it is only necessary to start the second motor 635 to run in reverse to loosen the auxiliary lifting rope 634, and then untie the limiting screw 647 to drive the side clamping plate 644 to move down and remove the side limiting group 64. At this time, the torsion spring 6453 is reset to drive the two L-shaped limiting arms 6455 to rotate outward, so that the side limiting group 64 is in an expanded state, and finally the third motor 652 is started to reverse, driving the two-way screw rod 653 to drive the two clamping arms 655 to move outward. This series of designs enables the device to quickly disassemble and assemble the steel structure component 4 during use, and to stably cover the two ends and the middle part of the fixed component during clamping, thereby ensuring the stability and safety of the steel structure component 4 during the lifting process.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
