Description

Technical Field

[0001] This utility model belongs to the field of bridge cable replacement technology, and particularly relates to a collapse prevention protection device based on cable cutting. Background Technology

[0002] With the rapid development of infrastructure construction in my country, especially the continuous increase in highways, high-speed railways, and urban bridges, the scale and span of bridges are constantly expanding. Long-span bridges place higher demands on the performance of bridge suspenders, while also facing issues such as the expiration of their service life and material aging. To ensure the safe operation of bridges, regular maintenance and replacement of key structural components such as suspenders have become essential.

[0003] Because the old suspenders typically pass through the end anchorage zone or narrow channels within the structure, and are encased in waterproof sleeves, shock absorbers, and other auxiliary structures, the anchorage end structure is complex and cannot be directly released and removed. Furthermore, the suspenders bear the bridge load for extended periods and possess internal tension. Attempting to pull them out entirely could cause the cable to rebound, swing, or the anchorage end to pop out uncontrollably due to a sudden release of tension, seriously threatening the safety of construction workers and the surrounding structure. Therefore, it is necessary to cut the old suspender wires in batches to gradually release the tension. During the batch cutting process, certain protective measures must be taken to avoid instantaneous energy loss and ensure the dismantling process is safe and controllable. Utility Model Content

[0004] The purpose of this invention is to provide a collapse protection device based on sling cutting, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a collapse protection device based on sling cutting, including a pair of collapse prevention mechanisms arranged vertically and covering and pressing the outside of the sling. The collapse prevention mechanisms apply a preload to the sling from its radial direction, and a cutting area is formed on the sling portion between the collapse prevention mechanisms. An adjustable clamping mechanism is provided between the collapse prevention mechanisms to achieve adjustable and relatively fixed spacing between the collapse prevention mechanisms.

[0006] In a further embodiment of this invention, the anti-collapse mechanism includes a pair of covering components that are fastened and pressed against the outside of the sling, and the covering components are assembled and fixed together.

[0007] In a further embodiment of this utility model, the covering component includes two bearing plates, two sleeves and connecting steel plates. Each bearing plate is provided with a sleeve, and each bearing plate is also provided with two connecting steel plates. The two connecting steel plates are located on both sides of the sleeve. The sleeve is a semi-cylindrical structure. The inner surface of the sleeve is adapted to the outer surface of the sling. The two sleeves form a sleeve that is fastened to the outside of the sling.

[0008] In a further embodiment of this invention, the covering component further includes several ribs, which are arranged in a ring array along the sleeve and fixed between the sleeve and the bearing plate.

[0009] In a further embodiment of this invention, a rubber gasket is provided between the inner wall of the hoop and the outer side of the sling.

[0010] In a further embodiment of this utility model, the adjusting clamping mechanism includes connecting bolts, which are distributed on both outer sides of the bearing plate and lock the upper and lower bearing plates together.

[0011] In a further embodiment of this utility model, the connecting steel plate, rib plate, sleeve and bearing plate are welded and fixed together.

[0012] The beneficial effects of this utility model are:

[0013] This device consists of two main parts: an anti-collapse mechanism and an adjusting clamping mechanism. The anti-collapse mechanism is fixed to the outside of the sling and is arranged in pairs, one above the other. The adjusting clamping mechanism is connected between the anti-collapse mechanisms, forming a cutting area between them. The anti-collapse mechanism applies radial preload to press the sling tightly against the outside of the sling. This prevents the sling from swinging, rebounding, and uncontrolled ejection of the anchor end when the sling is cut at the cutting area. This achieves high protection by cutting in batches, ensuring the safety of construction personnel. The adjusting clamping mechanism can set different lengths of the cutting area according to the length of the sling, allowing for flexible operation space. Attached Figure Description

[0022] This embodiment provides a collapse protection device based on sling cutting, including a pair of collapse prevention mechanisms. The collapse prevention mechanisms are arranged vertically and cover and press against the outside of the sling 8. The collapse prevention mechanisms apply a preload to the sling 8 from its radial direction, so that the collapse prevention mechanisms are tightly pressed against the outside of the sling 8.

[0023] In this embodiment, the anti-collapse mechanism forms a cutting area on the sling 8. An adjustable clamping mechanism is provided between the anti-collapse mechanism to achieve adjustable and relatively fixed spacing between the anti-collapse mechanism. The cutting area of ​​different lengths can be adjusted according to the length of the sling 8 to meet different actual operating space requirements.

[0024] In this embodiment, the anti-collapse mechanism further includes a pair of covering components that are fastened and pressed against the outside of the sling 8, and the covering components are assembled and fixed together.

[0025] In this embodiment, the covering assembly further includes two bearing plates 1, two sleeves 3, and connecting steel plates 4. Each bearing plate 1 is provided with a sleeve 3, and each bearing plate 1 is also provided with two connecting steel plates 4. The two connecting steel plates 4 are respectively located on both sides of the sleeve 3. The sleeve 3 is a semi-cylindrical structure. The inner surface of the sleeve 3 is adapted to the outer surface of the sling 8. The two sleeves 3 form a sleeve that is fastened to the outside of the sling 8. The same pair of bearing plates 1 are attached together by the two connecting steel plates 4 and locked and fixed by bolts 5, so that the covering assembly is fixed on the sling 8 as a whole. The two sleeves 3 apply a preload to the sling in the radial direction. This method simplifies the disassembly and assembly process between the covering assemblies.

[0026] The covering component also includes several ribs 2, which are arranged in a ring array along the sleeve 3 and fixed between the sleeve 3 and the bearing plate 1. The connecting steel plate 4, the ribs 2, the sleeve 3 and the bearing plate 1 are preferably fixed by welding, which has high reliability. The sleeve 3, the connecting steel plate 4 and the ribs 2 can also be fixed to the bearing plate 1 by detachable connection. The ribs 2 are triangular plates, which play a role in strengthening the structural strength of the connection between the sleeve 3 and the bearing plate 1.

[0027] In this embodiment, a rubber gasket 7 is further provided between the inner wall of the sleeve 3 and the outer side of the sling 8 to ensure that the contact force between the sleeve 3 and the sling 8 is uniform.

[0028] The adjusting clamping mechanism includes connecting bolts 6, which are distributed on both outer sides of the bearing plate 1 and lock the upper and lower bearing plates 1 together. The distance between the anti-collapse mechanisms can be adjusted and controlled by the connecting bolts 6 to generate cutting areas of different lengths. The sleeve 3 achieves the fastening effect at the break point of the sling 8, so that when the sling 8 is cut at the cutting area, it can avoid the swinging, rebounding of the sling body and uncontrolled ejection of the anchor end caused by the release of internal tension of the sling 8, thus achieving high protection of batch cutting and protecting the safety of construction personnel.

[0029] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
