Description
Technical Field
The utility model relates to a transparent protection casing of suspension cable tip belongs to bridge cable protection technical field.
Background
Compared with a beam bridge, the cable-stayed bridge has larger spanning capability and is an important structural form of a modern large-span bridge, and a cable-stayed suspension cable of the bridge mainly bears tension. Waterproof sealing of the bridge cable is an essential step of the cable-stayed bridge. Most of the existing bridge cable protective covers are rigid waterproof covers which are formed by welding stainless steel coils or cast iron in two-piece mode. However, these products generally have some defects, such as damage to the sealing part and water failure caused by vibration of the cable, high installation and maintenance costs, poor general applicability, and poor adaptability to different cable conduits, and the installation difficulty is significantly increased when the cable body and the cable conduit are eccentric. Although the rubber waterproof device for the bridge guy cable can partially solve the problems, the rubber waterproof device still has many urgent needs to be improved, for example, due to the difference of bridge structures, various combinations are generated for a cable body and a cable guide pipe, waterproof covers with various specifications are needed, the types of moulds are various, and the production and management cost is high. The traditional rubber protective cover is easy to damage and slide down due to the shaking of the stay cable, and the durability of the anchor head is affected by the fact that rainwater enters the damaged rubber protective cover and is easy to corrode the anchor head of the stay cable; the rubber waterproof device and the cable body connecting end are sealed by the hooping compression cover body rubber hooping the cable body, and the sealing measure can fail under the larger vibration action of the stay cable due to the poor cable diameter precision of the stay cable. The transition part between the cone and the cylinder of the rubber waterproof device is difficult to realize sealing, and when the cable body and the cable guide pipe are eccentric, the vibration of the cable is easy to cause cracking or sealing failure at the transition part, so that the applicability is poor; and the heavy dismantlement of iron matter protective cover in the box girder is inconvenient usually, and is very inconvenient to the inspection of anchor head at ordinary times, influences the progress etc. of inspection.
The utility model discloses focusing on solving the problem that aforementioned prior art exists, improving the life cycle and the actual protection effect of safety cover, the reduction personnel daily check degree of difficulty improves the progress and the efficiency of inspection.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a transparent protection casing of suspension cable tip for bridge cable end connection department downside.
The utility model provides a technical scheme: a transparent protective cover for the end part of a stay cable comprises a protective cover part, wherein the protective cover part is a transparent organic glass tube; the sealed end of transparent organic glass pipe is transparent organic glass, the open end of transparent organic glass pipe is equipped with annular metal connecting piece.
Preferably, a plurality of screw holes are preset in the annular metal connecting piece, and the annular metal connecting piece is fastened to be connected with the protective cover portion through fixing bolts.
Preferably, the annular metal connecting piece is sleeved at the opening end of the transparent organic glass tube, and the transparent organic glass tube is in threaded connection with the annular metal connecting piece.
Preferably, the transparent organic glass tube is provided with a breathable drain hole, and the breathable drain hole is provided with a thread in advance.
Has the advantages that: the utility model provides a transparent protection casing of suspension cable tip, transparent non-metallic material is chooseed for use to the translucent cover, and the little easy dismounting of whole quality makes things convenient for bridge maintainer to the inspection and the maintenance of bridge cable, can reduce later stage operation and maintenance cost.
