Description

Technical Field

[0001] The utility model relates to the technical field of hoisting devices, in particular to a hoisting device for an underground wall-connected steel cage. Background Art

[0002] The underground diaphragm wall casting process involves the hoisting of corner reinforcement cages, which are L-shaped when viewed from above. Existing cages primarily consist of vertically extending main bars and transversely arranged tie bars. With existing hoisting methods, the crane's hoisting rope is directly connected to the main bars. This can easily compress the tie bars when the cage is hoisted upward, causing the cage to deform. Furthermore, for special-shaped cages like corner cages, diagonal braces are often required between the hoisting points. Different cage sizes require different brace lengths, and custom braces are often required on-site, resulting in material waste and project delays. Utility Model Content

[0003] In order to solve the shortcomings of the existing lifting method, that is, the steel cage is easily deformed and requires customized diagonal braces, the utility model provides a steel cage lifting device with adjustable diagonal brace length and the steel cage is not easily deformed.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A lifting device for an underground wall-connected steel cage comprises a diagonal brace, a locking sleeve and a lifting ring installed at both ends of the diagonal brace, the locking sleeve can be locked on the main reinforcement of the steel cage, the lifting ring is used to connect the lifting rope of the crane, the diagonal brace comprises a sleeve, a sliding rod and a tightening bolt, one end of the sliding rod is slidably connected to the sleeve, and the tightening bolt is threadedly connected to the sleeve and abuts against the sliding rod.

[0006] Through the above settings, first, the locking sleeve can be locked on the main reinforcement. When the crane lifts the steel cage, the lifting device will not squeeze the tensioning bar of the lifting device, thereby preventing the steel cage from deformation. Second, the diagonal brace can be adjusted in length to adapt to steel cages of different sizes. There is no need to customize diagonal braces of a specific length, which saves materials and shortens construction time.

[0007] Furthermore, the locking sleeve includes two splints and fasteners, one end of the two splints are hinged to each other, and the other ends of the two splints are locked by fasteners so that the two splints clamp the main reinforcement of the steel cage, and the end of the diagonal brace is installed on the outside of one of the splints.

[0008] Through the above arrangement, the fastener drives the two clamping plates to clamp the main reinforcement.

[0009] Furthermore, the inner side of the splint is arc-shaped and is provided with a serrated structure.

[0010] Through the above settings, the friction between the splint and the main reinforcement is increased.

[0011] Furthermore, the ratio between the height of the upper and lower sides of the splint and the radius of the inner wall of the splint is greater than or equal to 2.

[0012] Through the above arrangement, sufficient contact area between the inner side of the splint and the main reinforcement is ensured, thereby improving the stability of the locking sleeve on the main reinforcement.

[0013] Furthermore, the fastener includes a bolt and a nut, the free end of the splint is provided with a connecting hole, the bolt passes through the connecting hole of the splint and cooperates with the nut thread.

[0014] Furthermore, the diagonal brace is made of stainless steel.

[0015] The above arrangement can prevent the diagonal braces from rusting. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 3 for Figure 1 Top view of . DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0020] like Figures 1 to 3 As shown, a lifting device for an underground wall-connected steel cage includes a diagonal brace 3, a locking sleeve 4 and a lifting ring 5 installed at both ends of the diagonal brace 3, the locking sleeve 4 can be locked on the main reinforcement 6 of the steel cage, the lifting ring 5 is used to connect the lifting rope of the crane, the diagonal brace 3 includes a sleeve 31, a sliding rod 32 and a tightening bolt 42133, one end of the sliding rod 32 is slidably connected to the sleeve 31, and the tightening bolt 42133 is threadedly connected to the sleeve 31 and abuts against the sliding rod 32.

[0021] Through the above arrangement, first, the locking sleeve 4 can be locked on the main reinforcement 6. When the crane lifts the steel cage, the lifting device will not squeeze the tensioning bar of the lifting device, thereby preventing the steel cage from being deformed. Second, the diagonal brace 3 can be adjusted in length to adapt to steel cages of different sizes. There is no need to customize the diagonal brace 3 of a specific length, thereby saving materials and shortening the construction period.

[0022] The hoisting device of the present application is particularly suitable for L-shaped corner steel cage used in low-rise wall construction. When hoisting the steel cage, Figure 1As shown, the diagonal brace 3 is placed on the inner side of the steel cage, and the locking sleeve 4 at the end of the diagonal brace 3 is locked on the upper end of the corresponding main reinforcement 6. The upper side of the locking sleeve 4 does not contact the laterally extending tension reinforcement. After the crane's lifting rope is connected to the lifting rings 5 ​​at both ends of the diagonal brace 3, the steel cage is lifted upward, and the tension of the lifting rope acts on the main reinforcement 6 through the locking sleeve 4. The main reinforcement 6 is relatively thick and not easy to deform. Moreover, since the locking sleeve 4 is locked on the main reinforcement 6, the locking sleeve 4 will not act on the tension reinforcement upward to prevent the tension reinforcement from deformation. At the same time, the diagonal brace 3 supports the two ends of the steel cage to prevent the overall deformation of the steel cage; the lifting ring 5 of the present application is welded to the upper side of the end of the sleeve 31 away from the sliding rod 32, and the upper side of the end of the sliding rod 32 away from the sleeve 31; the locking sleeve 4 is welded to the end of the sleeve 31 away from the sliding rod 32, and the end of the sliding rod 32 away from the sleeve 31. The sleeve 31 is made of a round tube, and the sliding rod 32 is made of a round rod that matches the sleeve 31. The sliding rod 32 is not easy to shake when sliding in the sleeve 31. After the tightening bolt 42133 is tightened, the tightening bolt 42133 is pressed against the sliding rod 32 to lock the sliding rod 32 in the sleeve 31, thereby fixing the length of the diagonal brace 3. Loosen the tightening bolt 42133, the tightening bolt 42133 loosens the sliding rod 32, and the sliding rod 32 can slide axially in the sleeve 31 to adjust the length of the diagonal brace 3.

[0023] As an implementation method, the locking sleeve 4 includes two splints 41 and a fastener 42. One end of the two splints 41 is hinged to each other, and the other end of the two splints 41 is locked by the fastener 42 so that the two splints 41 clamp the main reinforcement 6 of the steel cage, and the end of the diagonal brace 3 is installed on the outside of one of the splints 41.

[0024] Through the above arrangement, the fastener 42 drives the two clamping plates 41 to clamp the main reinforcement 6 .

[0025] The clamping plates 41 and fasteners 42 of this application are made of metal to ensure strength. The clamping plates 41 are generally arc-shaped to match the main reinforcement 6. When clamping the main reinforcement 6, the inner side of the clamping plates 41 can basically contact the main reinforcement 6, ensuring friction. After the fasteners 42 are removed, the two clamping plates 41 can be opened and closed freely. The clamping plates 41 are placed on the left and right sides of the main reinforcement 6, and the free ends of the two clamping plates 41 are locked together using the fasteners 42. The clamping plates 41 clamp the main reinforcement 6.

[0026] As an implementation method, the inner side of the splint 41 is arc-shaped, and a serration structure (not shown in the figure) is provided on the inner side of the splint 41 .

[0027] Through the above arrangement, the friction between the clamping plate 41 and the main rib 6 is increased.

[0028] As an implementation method, the ratio between the height of the upper and lower sides of the clamping plate 41 and the radius of the inner wall of the clamping plate 41 is greater than or equal to 2.

[0029] Through the above arrangement, sufficient contact area is ensured between the inner side of the splint 41 and the main rib 6 , thereby improving the stability of the locking sleeve 4 on the main rib 6 .

[0030] As an implementation manner, the fastener 42 includes a bolt 421 and a nut 422 . A connecting hole is provided at the free end of the clamping plate 41 . The bolt 421 passes through the connecting hole of the clamping plate 41 and is threadedly engaged with the nut 422 .

[0031] The nut 422 and the head of the bolt 421 clamp the free ends of the two splints 41 to prevent the two splints 41 from opening. When the nut 422 is tightened, the nut 422 and the head of the bolt 421 close the splints 41, and the splints 41 clamp the main reinforcement 6.

[0032] As an implementation method, the material of the diagonal brace 3 is stainless steel.

[0033] The above arrangement prevents the diagonal brace 3 from rusting.

[0034] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
