DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1, Reference Figures 1 to 14 A construction site steel structure hoisting device shown includes an adjustment mechanism 4 and a hoisting mechanism 2 for hoisting steel structure members, the adjustment mechanism 4 is used to adjust the placement angle of the hoisting mechanism 2, support mechanisms 3 are provided on both sides of the adjustment mechanism 4, and a connecting mechanism 1 is provided at the middle of the upper end of the adjustment mechanism 4; It is worth noting that the lifting and lowering of the connecting mechanism 1 is controlled by the cable of the crane, the connecting mechanism 1 drives the adjusting mechanism 4 to move up and down, and then the adjusting mechanism 4 controls the lifting and lowering of the hoisting mechanism 2; When lifting the steel structure, the hoisting mechanism 2 absorbs and binds the steel structure. When splicing and installing the steel structure, the inclination angle of the hoisting mechanism 2 is controlled by the adjustment mechanism 4, thereby controlling the installation position and angle of the steel structure. Among them, by adjusting the angle of the lifting mechanism 2 through the adjustment mechanism 4, the position adjustment can be achieved during the steel structure lifting process to ensure that the steel structure can be accurately aligned during installation. Since the position and angle of the steel structure can be directly adjusted in the air, the error accumulation that may occur during ground assembly is reduced, thereby improving the overall installation accuracy.

[0023] The adjustment mechanism 4 and the lifting mechanism 2 are not only suitable for conventional vertical lifting tasks, but also can cope with situations that require specific angle or position adjustment, such as the installation of complex structures such as high-rise buildings and bridges. They can flexibly adjust the lifting angle so that the lifting task can be successfully completed in narrow spaces or environments with obstacles.

[0024] When the hoisting mechanism 2 is tilted, the hoisting mechanism 2 drives the steel structure to tilt, and the supporting mechanism 3 supports the tilted steel structure to prevent the steel structure from tilting excessively and squeezing the adjusting mechanism 4.

[0025] Among them, the support mechanism 3 provides additional support to ensure that the steel structure remains stable when adjusting the angle, avoids position deviation due to excessive tilt, improves the accuracy of installation, and ensures that the steel structure will not lose control due to excessive tilt. The operator can make subtle angle adjustments under safer and more stable conditions to ensure the accuracy of the installation position.

[0026] The support mechanism 3 prevents the steel structure from tilting excessively, reduces the risk of the steel structure directly squeezing the adjustment mechanism 4, and reduces the possibility of the steel structure suddenly falling or losing control by providing additional support, thereby ensuring the safety of construction workers and reducing potential safety hazards.

[0027] The presence of the support mechanism 3 allows the operator to adjust the angle more confidently without worrying about problems caused by excessive tilting of the steel structure, thereby speeding up the installation process.

[0028] Since the steel structure can be adjusted in an angle under a controlled state, the need for readjustment after installation is reduced. The support mechanism 3 enhances its adaptability to complex environments, which is particularly important in the construction of high-rise buildings or bridges where fine adjustments need to be made in the air. The design of the support mechanism 3 allows the steel structure to remain stable at different angles and can flexibly respond to various complex installation requirements.

[0029] Embodiment 2: Based on the hoisting mechanism 2, connecting mechanism 1 and adjusting mechanism 4 provided in embodiment 1, this embodiment provides a further technical solution for the hoisting mechanism 2, connecting mechanism 1 and adjusting mechanism 4.

[0030] The lifting mechanism 2 includes a first structural frame 22, and hinge blocks 27 are provided at the four corners of the upper end of the first structural frame 22. Side frames 25 are provided at both ends of the first structural frame 22. Connecting buckles 24 are symmetrically provided on one side of the outer surface of the two side frames 25. Binding ropes 23 are provided inside the two connecting buckles 24. An electromagnetic plate 21 is provided at the lower end of the first structural frame 22.

[0031] It is worth mentioning that when in use, the electromagnetic plate 21 is energized to adsorb the steel structure to be transported, and the electromagnetic plate 21 belongs to the prior art and is not described here in detail. When the electromagnetic plate 21 is adsorbed and connected, the steel structure is bundled by the binding rope 23, and the connecting buckle 24 uses a conventional cable fixing part to fix the binding rope 23 to prevent the transported steel structure from loosening.

[0032] The connecting mechanism 1 includes a hanger 11 , and two shafts 13 are symmetrically arranged inside the hanger 11 . Hanging wheels 12 are rotatably mounted on the outer surfaces of the two shafts 13 . The hanger 11 is fixedly mounted on the upper end of the load-bearing frame 42 .

[0033] It is worth noting that the lifting wheel 12 is connected to the rope on the crane, and the contraction of the rope drives the lifting wheel 12 to rotate on the shaft 13, and then drives the adjusting mechanism 4 to be lifted or lowered through the hanger 11.

[0034] A control box 44 is disposed inside the load-bearing frame 42 . A cable 43 is disposed at the bottom of the control box 44 . One end of the cable 43 is electrically connected to the electromagnetic plate 21 .

[0035] A support frame 47 and a differential case 413 are respectively disposed at the upper ends of the two second structural frames 45 . A drive motor 48 is disposed at one end of the differential case 413 . A rope drum 46 is disposed between the differential case 413 and the support frame 47 .

[0036] It is worth noting that when in use, the output shaft of the driving motor 48 drives the gear inside the differential case 413 to rotate, and the gear drives the cable drum 46 to rotate, and the cable drum 46 rotates to retract and release the load-bearing cable 29. Since the load-bearing cable 29 is connected to the cable wheel 26, the load-bearing cable 29 mainly provides the main support force for the first structural frame 22; A middle support frame 411 is arranged between the two second structural frames 45, and a support rod 415 is arranged at the upper end of the middle support frame 411. The outer surface of the support rod 415 is symmetrically provided with a control cable wheel 414, and a support wheel 412 is rotatably installed inside the middle support frame 411. The outer surfaces of the two support wheels 412 and the control cable wheel 414 are both wound with a load-bearing cable 29, and the load-bearing cable 29 is wound around the outer surface of the rope drum 46.

[0037] In order to ensure that the above-mentioned load-bearing cable 29 lifting rope wheel 26 is always at the same angle and will not change, the load-bearing cable 29 is guided by the control rope wheel 414 when it is retracted and released, and then the load-bearing cable 29 is guided and wound around the support wheel 412. When the load-bearing cable 29 is retracted and released, it will drive the support wheel 412 and the control rope wheel 414 to rotate, and the two support wheels 412 are set to expand the line around the load-bearing cable 29 into a triangular shape, in order to ensure that the retracted and released load-bearing cables 29 will not be staggered.

[0038] Among them, through the design of the cable control wheel 414 and the support wheel 412, it is ensured that the load-bearing cable 29 always maintains the same relative angle with the cable wheel 26 during the retraction and release process, and the angle consistency of the hoisted object is maintained, thereby improving the accuracy of the installation position. The two support wheels 412 wind the load-bearing cable 29 into a triangular shape to increase stability and prevent the load-bearing cable 29 from being intertwined, thereby ensuring smoothness and controllability during the hoisting process.

[0039] The arrangement of the support wheel 412 and the cable control wheel 414 effectively avoids the crossing and entanglement between the load-bearing cables 29. The load-bearing cables 29 provide the main supporting force for the first structural frame 22 by being wound around the cable wheel 26, thereby ensuring the stability of the hoisted object during the entire hoisting process and reducing the risk of accidental falling.

[0040] The use of the drive motor 48 and the differential case 413 enables precise control of the rotation speed of the rope drum 46. The rotation speed and direction of the rope drum 46 can be flexibly adjusted through the differential case 413 and gear transmission.

[0041] A cable pulley 26 is disposed in the middle of the upper end of the first structural frame 22 , a load-bearing cable 29 is wound around the cable pulley 26 , and steel cables 28 are disposed inside the four hinge blocks 27 .

[0042] The adjusting mechanism 4 includes a load-bearing frame 42, side panels 41 are provided on both sides of the load-bearing frame 42, two second structural frames 45 are symmetrically provided at the lower end of the load-bearing frame 42, two regulating motors 416 are symmetrically provided on one side of the two second structural frames 45, the output ends of the two regulating motors 416 extend to the interior of the second structural frame 45 and are fixedly installed with a control wheel 49, and the tying rope 23 is wrapped around the outer surface of the control wheel 49.

[0043] When the steel structure is lifted to the designated installation position and the installation position and installation angle of the steel structure need to be adjusted, the control wheel 49 is driven to rotate by the regulating motor 416, and the four regulating motors 416 can be controlled to rotate individually, and the control wheel 49 is driven to rotate by simultaneously controlling the rotation of the two regulating motors 416 on one side. The regulating motor 416 is operated by the integrated sensor and the automatic control system, and the rotation of the control wheel 49 retracts and releases the steel cable 28, and then the steel cable 28 pulls the hinge block 27 to drive the first structural frame 22 to deflect and move; When the first structural frame 22 deflects, the load-bearing cable 29 will also drive the cable pulley 26 to move. Since the position of the cable pulley 26 will also change when the first structural frame 22 deflects, the load-bearing cable 29 provides the main load-bearing force for the first structural frame 22, so the load-bearing cable 29 will also be retracted and released accordingly. The contraction of the four steel cables 28 can control the deflection of the steel structure at any angle, so that the suspended steel structure can be corrected at the installation position at will without the need for additional rope traction correction.

[0044] Among them, the four regulating motors 416 can be controlled individually or in combination, allowing the operator to fine-tune the position and angle of the steel structure to ensure that it can be accurately installed in the specified position.

[0045] By simultaneously controlling the two regulating motors 416 on one side, the steel structure can be deflected in any direction to meet different installation requirements. Even when the steel structure is deflected, the load-bearing cable 29 still provides the main load-bearing force for the first structure frame 22, ensuring stability during the lifting process and reducing the risk of accidents.

[0046] The design of the control motor 416 enables the steel structure to deflect in a controlled state, avoiding excessive tilting or swinging due to external forces. The use of the control motor 416 realizes the rapid adjustment of the position and angle of the steel structure. Since the position and angle of the steel structure can be directly adjusted in the air, the workload of secondary adjustments after ground assembly is reduced. It can flexibly respond to various complex installation requirements and is suitable for situations that require multi-angle and multi-directional adjustments, such as the installation of steel structures in high-rise buildings or bridge construction. The angle adjustment of the steel structure can be completed by contracting the four steel cables 28, without the need for additional traction ropes, thereby simplifying the on-site operation process.

[0047] Embodiment 3: Based on the support mechanism 3 proposed in Embodiment 1, this embodiment provides a further technical solution of the support mechanism 3.

[0048] The supporting mechanism 3 includes a roller 35, a connecting rod 31 and two pneumatic rods 34. The connecting rod 31 is fixedly mounted on one side of the side plate 41. One ends of the two pneumatic rods 34 are rotatably mounted on one side of the side plate 41. The outer surface of the connecting rod 31 is rotatably mounted with a side rod 32. The inside of the two side rods 32 is rotatably mounted with a center rod 33, and both ends of the center rod 33 are rotatably connected to one end of the pneumatic rod 34.

[0049] It is worth noting that when the first structural frame 22 deflects to drive the steel structural member to deflect, in order to prevent the deflected steel structural member from excessively deflecting and squeezing the driving member inside the adjustment mechanism 4 .

[0050] A sleeve 37 is rotatably mounted on the outer surface of the center rod 33 . A plurality of conical springs 36 distributed in a ring array are arranged on the outer surface of the sleeve 37 . The roller 35 is sleeved on the outer surfaces of the plurality of conical springs 36 .

[0051] Among them, when the steel structure is deflected and contacts the roller 35, the roller 35 is squeezed and then squeezes the conical spring 36. When the conical spring 36 is under greater pressure and cannot continue to shrink, the sleeve 37 will squeeze the pneumatic rod 34 through the center rod 33 to withstand additional squeezing force. When the pneumatic rod 34 shrinks, the two ends will rotate on the center rod 33 and the side plate 41, and the side rod 32 will also rotate accordingly. When the steel structure moves, there is friction between the roller 35 and the steel structure, so the sleeve 37 will be driven to rotate on the outer surface of the center rod 33 through the roller 35 and the conical spring 36.

[0052] Among them, when the steel structure deflects and contacts the roller 35, part of the pressure is first absorbed by the conical spring 36. If the pressure continues to increase and the conical spring 36 cannot continue to contract, the sleeve 37 will squeeze the pneumatic rod 34 through the center rod 33 to form a multi-stage buffer mechanism, which effectively prevents the excessive deflection of the steel structure from causing direct impact and damage to the internal driving parts of the adjustment mechanism 4. When the pneumatic rod 34 contracts, its two ends will rotate on the center rod 33 and the side plate 41, and can automatically adjust according to changes in external pressure to maintain stable deflection of the structure. The rolling contact between the roller 35 and the steel structure reduces friction, thereby reducing the possibility of vibration transmission to the adjustment mechanism 4 and enhancing the overall stability.

[0053] The combination of the gas rod 34 and the conical spring 36 can provide additional cushioning in extreme situations to prevent damage to personnel and equipment when accidents occur. By monitoring the status of the conical spring 36 and the gas rod 34, the deflection of the steel structure can be understood in real time, and timely measures can be taken to avoid potential risks.

[0054] The design of roller 35 reduces the friction when the steel structure moves, making the deflection process smoother and improving the comfort and efficiency of operation. Due to the existence of roller 35, the direct contact between the steel structure and the fixed structure is reduced. The multi-stage buffer mechanism can self-regulate to a certain extent, reducing the need for frequent maintenance caused by external pressure changes.

[0055] The present invention also provides a hoisting method for a steel component hoisting device at a construction site, and the specific operation method is as follows: S1. The lifting and lowering of the connecting mechanism 1 is controlled by the cable of the crane, the connecting mechanism 1 drives the adjusting mechanism 4 to move up and down, and then the adjusting mechanism 4 controls the lifting and lowering of the hoisting mechanism 2; S2. When lifting the steel structure, the lifting mechanism 2 absorbs and binds the steel structure. When splicing and installing the steel structure, the inclination angle of the lifting mechanism 2 is controlled by the adjustment mechanism 4, thereby controlling the installation position and angle of the steel structure. S3. When the hoisting mechanism 2 is tilted, the hoisting mechanism 2 drives the steel structure to tilt, and the supporting mechanism 3 supports the tilted steel structure to prevent the steel structure from tilting excessively and squeezing the adjusting mechanism 4.

[0056] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
