Embodiment Construction

[0016] Specific embodiments of the present invention will be further described in detail below. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.

[0017] Such as figure 1 As shown, it is a cross-sectional schematic diagram of a cable end waterproof sealing device using a skeleton spring sealing ring provided by the present invention. The cable end waterproof sealing device using the skeleton spring seal ring is used to cooperate with an anchor connecting cylinder 20 sleeved on the cable end of a cable 10 to achieve sealing between the cable 10 and the cable. The purpose of the anchor connecting cylinder 20. The cable end of the stay cable 10 is installed on the anchor through the anchor connecting cylinder 20 to realize the fixation of the stay cable. It is a prior art, and will not be repeated here.

Abstract

An inhaul cable end waterproof sealing device using a framework spring sealing ring comprises a rubber sealing ring arranged on an inhaul cable in a sleeving mode, a two-way groove pressing ring arranged on one side of the rubber sealing ring, a threaded pressing ring arranged on one side of the two-way groove pressing ring and a sealing ring arranged on the other side of the two-way groove pressing ring. And the framework spring sealing ring is arranged on one side of the threaded pressing ring. The framework spring sealing ring comprises an inner groove rubber ring arranged on one side of the threaded pressing ring and an annular steel framework arranged in the inner groove rubber ring. The annular steel framework comprises an outer ring and an inner ring integrally formed with the outer ring. The outer ring protrudes out of the inner ring in the direction facing the hole opening of the anchorage device connecting cylinder, and the inner ring protrudes out of the outer ring in the direction facing the auxiliary sealing lip. Compared with a traditional rubber sealing ring, the framework spring sealing ring is more excellent in structure rigidity, longer in service life, more durable in sealing structure and better in anti-shaking effect.

Description

technical field [0001] The invention relates to the technical field of anchor protection at the cable end, in particular to a waterproof sealing device at the cable end using a skeleton spring sealing ring. Background technique [0002] Stay cables are the main load-bearing components of bridges and other span structures. They are exposed to wind, rain, humidity, or polluted air for a long time, so their durability directly affects the safety, economy and reliability of bridges. The joint between the cable body and the anchor is the weak link in the anti-corrosion of the cable. Therefore, the research on the anchor protection at the end of the cable has become a key point in the research of bridge protection. [0003] For example, the Chinese patent CN105256721B discloses a waterproof sealing structure at the end of the cable. This structure uses a sealing cover for the first seal, and uses an elastic sealing ring and a sealing pressure ring on the inner wall of the connecti...
