Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular, to a steel cage hoisting device and a using method thereof. Background Art

[0002] The steel cage is an important part of the diaphragm wall. In the construction of the diaphragm wall, it is necessary to hoist the steel cage to the construction position and pour concrete. When hoisting the steel cage, a main hoisting member and an auxiliary hoisting member are usually set to hoist the steel cage simultaneously. During the entire hoisting process of the steel cage, the main hoisting member is responsible for bearing most of the weight of the steel cage, that is, playing a major load-bearing role during the hoisting process.

[0003] In the prior art, a hoisting plate is usually set as the main hoisting member. A plurality of through holes are opened at both the upper and lower ends of the hoisting plate. A plurality of wire ropes are passed through the through holes at the upper end and connected to a hoisting machine. A plurality of pulleys are connected to the through holes at the lower end, and the wire ropes are passed through the pulleys and then connected to the steel cage. To ensure the safety of the hoisting work, it is usually defaulted that the plurality of wire ropes evenly divide the weight of the steel cage. Then, according to the weight of the steel cage and the load-bearing range of the wire ropes, the number of wire ropes is determined. Finally, the plurality of wire ropes are connected to the steel cage at uniform intervals. However, in actual construction, there are steel cages with irregular shapes. The center of gravity of this type of steel cage usually deviates from its central position. If only a plurality of wire ropes are connected at uniform intervals, on the one hand, the forces on the plurality of wire ropes are uneven, and on the other hand, the force magnitudes of the individual wire ropes cannot be determined. Therefore, it is impossible to determine whether the forces on the individual wire ropes exceed the load-bearing range of the wire ropes, so there is a possibility that the wire ropes may break and fail due to excessive load. Seriously, it will cause the steel cage to fall and be damaged, and it will also injure the nearby workers, causing safety accidents. Summary of the Invention

[0041] Embodiment 1

[0042] This embodiment provides a steel cage hoisting device. As Figures 1 to 3 shown, it can visually judge whether the hoisting connecting member 15 is evenly stressed, and can clarify the stress magnitude of the hoisting connecting member 15, thereby preventing the steel cage 300 from falling and being damaged due to the fracture and failure of the hoisting connecting member 15, ensuring the safety of the hoisting work, and avoiding safety accidents.

[0043] like Figures 1 to 3 As shown, the steel cage hoisting device includes a main hoisting assembly 1 and a secondary hoisting assembly 2. The main hoisting assembly 1 includes a main hoisting beam 11, a plurality of hoisting connectors 12, a plurality of hanging connectors 13, a plurality of slings 14 and a plurality of hoisting connectors 15. The plurality of hoisting connectors 12 and the plurality of hanging connectors 13 are vertically arranged on both sides of the main hoisting beam 11, and are all detachably connected to the main hoisting beam 11. The end of the hoisting connector 12 away from the main hoisting beam 11 is configured to be connected to the first hoisting device 100, and the end of the hanging connector 13 away from the main hoisting beam 11 is detachably connected to the sling 14. The plurality of hanging connectors 13 correspond to the plurality of slings 14 one by one. Each sling 14 is connected to a plurality of hoisting connectors 15, and the end of the hoisting connector 15 away from the sling 14 is configured to be connected to the steel cage 300. The auxiliary suspension assembly 2 includes an auxiliary suspension beam 21, a first auxiliary suspension connection member 22 and a second auxiliary suspension connection member 23. The first auxiliary suspension connection member 22 and the second auxiliary suspension connection member 23 are vertically connected to both sides of the auxiliary suspension beam 21. The end of the first auxiliary suspension connection member 22 away from the auxiliary suspension beam 21 is configured to be connected to the second lifting device 200, and the end of the second auxiliary suspension connection member 23 away from the auxiliary suspension beam 21 is configured to be connected to the steel cage 300.

[0044] When lifting the steel cage 300, first assemble the main lifting assembly 1 and the auxiliary lifting assembly 2, then connect the lifting connector 15 of the main lifting assembly 1 and the second auxiliary lifting connector 23 of the auxiliary lifting assembly 2 to the steel cage 300, and connect the first lifting device 100 to the lifting connector 12 and the second lifting device 200 to the first auxiliary lifting connector 22, then control the first lifting device 100 and the second lifting device 200 to lift the steel cage 300 vertically to lift it off the ground, observe the status of the main lifting beam 11 and the sling 14 of the main lifting assembly 1, If the main lifting beam 11 is in an inclined state and the sling 14 is offset in the vertical direction, it means that the multiple lifting connectors 15 are unevenly stressed. By detecting the offset angle of the sling 14 and combining it with relevant mechanical analysis, the tension on each lifting connector 15 can be calculated, so as to determine whether the tension on the lifting connector 15 exceeds its load-bearing range. By adjusting the length and installation position of the lifting connection, the main lifting beam 11 can be horizontal in the vertical plane and the sling 14 can be vertical. At this time, the multiple lifting connectors 15 are evenly stressed.

[0045] By setting the main lifting beam 11 and the lifting device 14, it is possible to intuitively judge whether the multiple lifting connectors 15 are evenly stressed, and to clarify the magnitude of the stress on the lifting connectors 15, so as to adjust the length and installation position of the lifting connectors 15 based on this, so that the lifting connectors 15 are evenly stressed, thereby preventing the steel cage 300 from falling and being damaged due to the failure of the lifting connectors 15, thereby ensuring the safety of the lifting work and avoiding safety accidents.

[0046] Exemplarily, the lifting connection member 12 includes a steel wire rope, the hoisting connection member 15 includes a steel wire rope, the first hoisting device 100 includes a crane, and the second hoisting device 200 includes a crane.

[0047] In this embodiment, there are 2 sling tools 14, 4 lifting connection members 12, 2 hanging connection members 13, and 4 hoisting connection members 15. In other embodiments, other quantities of sling tools 14, lifting connection members 12, hanging connection members 13, and hoisting connection members 15 may also be set according to actual needs, and the quantities of the above four are not limited herein.

[0048] Optionally, as Figures 1 to 3 shown, the main hoisting structure of the hoisting device further includes a plurality of first shackles 3. A plurality of through holes one 111 are opened at the upper end of the main hoisting cross beam 11, and the plurality of lifting connection members 12 are connected to the plurality of through holes one 111 one by one through the plurality of first shackles 3. When assembling the main hoisting assembly 1, first pass the first shackle 3 through the through hole one 111 of the main hoisting cross beam 11, and then pass one end of the lifting connection member 12 through the first shackle 3, so as to connect the lifting connection member 12 and the main hoisting cross beam 11, so that the first hoisting device 100 is connected to the main hoisting assembly 1, and the structural form is simple and the operation is convenient.

[0049] Exemplarily, there are 4 through holes one 111, and correspondingly 4 first shackles 3 are provided. In other embodiments, other quantities of through holes one 111 and first shackles 3 may also be set according to actual needs, and the quantities of the above two are not limited herein.

[0050] Optionally, as Figures 1 to 3 shown, a plurality of through holes two 112 are opened at the lower end of the main hoisting cross beam 11, a through hole three is opened in the sling tool 14, and the hanging connection member 13 includes a plurality of second shackles 131. The plurality of second shackles 131 are sequentially passed through and connected in the vertical direction, and the hanging connection member 13 is connected to the through hole two 112 through the uppermost second shackle 131, and the hanging connection member 13 is connected to the through hole three through the lowermost second shackle 131. When assembling the main hoisting assembly 1, first sequentially pass through and connect the plurality of second shackles 131 to form the hanging connection member 13, and then pass the uppermost second shackle 131 through and connect it in the through hole two 112 of the main hoisting cross beam 11, and the lowermost second shackle 131 through and connect it in the through hole three of the sling tool 14, so that the sling tool 14 is connected to the main hoisting cross beam 11, and the structural form is simple and the operation is convenient.

[0051] In this embodiment, each main lifting beam 11 is provided with two through holes 112. In other embodiments, more than two through holes 112 may be provided according to actual needs. When the steel cage 300 needs to be hoisted, the installation position of the hoisting device 14 on the main lifting beam 11 may be flexibly adjusted according to the shape of the steel cage 300, so that the force at the lifting point of the steel cage 300 is balanced, which is conducive to ensuring the stability of the steel cage 300 during the hoisting process and improving the safety of the hoisting of the steel cage 300. The number of through holes 112 is not limited.

[0052] In some embodiments, the lower end of the main suspension beam 11 is provided with a plurality of through holes 2 112, and the sling 14 is provided with a through hole 3. The suspension connector 13 includes a suspension chain, a third shackle and a fourth shackle, one end of the suspension chain is connected to the through hole 2 112 through the third shackle, and the other end is connected to the through hole 3 through the fourth shackle. When assembling the main suspension assembly 1, firstly, the third shackle and the fourth shackle are respectively connected to the two ends of the suspension chain, and then the third shackle is penetrated and connected to the through hole 2 112 of the main suspension beam 11, and the fourth shackle is penetrated and connected to the through hole 3 of the sling 14. By setting the suspension chain to penetrate and connect with the third shackle and the fourth shackle, the connection points can be reduced, making the overall structure more stable. At the same time, the suspension chain usually has a good load-bearing capacity and can meet safety requirements.

[0053] Alternatively, if Figures 1 to 3 As shown, a plurality of through holes 142 are provided at one end of the sling 14 away from the main sling beam 11, and the plurality of through holes 142 are symmetrically distributed along the central axis of the sling 14. By symmetrically arranging the plurality of through holes 142 on the sling 14, the plurality of hoisting connectors 15 can be symmetrically distributed, thereby ensuring that the steel cage 300 is subjected to balanced force during the hoisting process, helping to prevent tilting or shaking caused by uneven force, and improving the stability and safety of the hoisting operation.

[0054] Exemplarily, each sling 14 is provided with two through holes 24 142. In other embodiments, other numbers of through holes 24 142 may be provided according to actual needs, which is not limited here.

[0055] It should be noted that, in the present embodiment, the shape of the hanger 14 is an isosceles triangle, and the number of the through holes 142 is an even number.

[0056] Optionally, the main lifting structure of the lifting device further includes a fifth shackle and a fixed pulley crane. The fifth shackle is connected through the through hole 142, the fixed pulley crane is hooked on the fifth shackle, and the lifting connector 15 is wound around the fixed pulley crane and connected to the steel cage 300. By providing the fifth shackle, the fixed pulley crane can be flexibly installed and removed, which increases the flexibility and maintainability of the system, and the lifting connector 15 is wound around the fixed pulley crane, which can change the direction of the lifting connector 15, so that the lifting connector 15 can be changed from a vertical or nearly vertical direction to a direction more suitable for lifting operations, and the fixed pulley crane can provide a stable lifting point, thereby enhancing the safety of the lifting operation.

[0057] Optionally, the main lifting structure of the lifting device also includes a reinforcing plate. The reinforcing plate is arranged on the sling 14 and is arranged around the circumference of the through hole 142. By providing the reinforcing plate, the local strength around the through hole 142 can be significantly improved. Since the through hole 142 is a stress concentration area, the presence of the reinforcing plate can effectively disperse and reduce the stress concentration in this area, optimize the stress distribution on the sling 14, reduce the risk of stress concentration and local damage, and improve the load-bearing capacity of the entire sling 14. In addition, the reinforcing plate can also increase the overall rigidity of the sling 14, help reduce the deformation and vibration of the sling 14 during the lifting process, and improve the stability and reliability of the overall structure.

[0058] In this embodiment, if Figures 1 to 3 As shown, the steel cage hoisting device further includes a connecting plate 5 and a sixth shackle 4. The connecting plate 5 is arranged on the steel cage 300, and a through hole 51 is opened on the connecting plate 5. The hoisting connector 15 is connected to the through hole 51 through the sixth shackle 4. When connecting the hoisting connector 15 and the steel cage 300, it is only necessary to connect the sixth shackle 4 to the hoisting connector 15, and to pass the sixth shackle 4 through the through hole 51. The structure is simple and the operation is convenient.
