Compared with the prior art, the utility model has the beneficial effects that: through the chill anchor that sets up fixed hoist cable and girder to and pass through the pre-buried steel pipe structure of bolt fastening with the girder, can avoid unexpected the emergence when making single fixed mode appear droing, thereby realize secondary anchor's effect, also can satisfy the needs that jib ground tackle rested the replacement simultaneously.
Through set up locking inner chamber and shock attenuation inner chamber in pre-buried steel pipe, when the cast anchor accident appears droing, because the effect of gravity can make cable end sealing mechanism insert the locking protruding in, pre-buried steel pipe is when big more to cable end sealing mechanism generate pressure, and its secondary anchor power is big more. Prevent that girder and hoist cable from taking place to drop, increase the security of bridge.
Through the shock attenuation inner chamber that sets up to have the shock absorber, can reduce the vibration of secondary anchor hoist cable and the resonance of hoist cable and girder to the effect that prevents the corrosion has been reached.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a secondary anchoring vibration reduction arch bridge suspender comprises a sling 1, wherein the sling 1 is connected with a main beam 14 through a cold casting anchor 7, and a cold casting anchor protective sleeve 6 is arranged on the cold casting anchor 7, so that direct contact between the cold casting anchor 7 and the external environment is reduced. An embedded steel pipe 9 is arranged outside the sling 1, the end tail of the embedded steel pipe 9 is connected with a cold-cast anchor 7 through a cold-cast anchor backing plate 8, the cold-cast anchor backing plate 8 is arranged on the outer wall of the cold-cast anchor 7, and one end of the cold-cast anchor 7 is arranged in a locking inner cavity of the embedded steel pipe 9. A pair of steel backing plates 12 are arranged on two sides of the embedded steel pipe 9, the steel backing plates 12 are connected with the cold-cast anchor pads 8 through bolts 13, the bolts 13 penetrate through the main beam 14, and the secondary anchoring effect is achieved through the fixation of the embedded steel pipe 9 and the main beam 14. The end of the embedded steel pipe 9 is connected with the sling 1 through the sleeve 2. The sleeve 2 is fixed with the sling 1 and the embedded steel pipe 9 through the stainless steel hoop 11, and the rubber gasket 4 is arranged in the stainless steel hoop 11, so that rainwater is prevented from entering and rusting.
A locking inner cavity and a damping inner cavity are arranged in the embedded steel pipe 9.
The inner wall of the locking inner cavity is provided with a locking protrusion, the inner diameter of the locking protrusion gradually decreases from the end tail to the end head, the sling 1 is provided with a cable end sealing mechanism 5, and the shape of the cable end sealing mechanism 5 is matched with that of the locking protrusion; when the chill casting anchor 7 falls off, the sling 1 is pulled upwards, and the sling end sealing mechanism 5 moves upwards and is clamped in the locking protrusion at the locking inner cavity, so that the sling 1 is tightly locked to avoid accidents. Meanwhile, the secondary anchoring structure can meet the requirement of the replacement of the suspender anchor after the rest.
The shock absorber 10 is arranged in the shock absorption inner cavity, one end of the shock absorber 10 is connected with the locking protrusion, the other end of the shock absorber 10 is connected with the end of the embedded steel pipe 9 and used for reducing vibration of the secondary anchoring sling and resonance of the sling 1 and the main beam 14, the shock absorption inner cavity is filled with epoxy resin 3 to prevent corrosion, and meanwhile, the epoxy resin 3 can be replaced by kerosene. Shock absorber 10 is a damped spring shock absorber.
The working principle is as follows: the sling 1 is fixed with the main beam 14 through the cold-cast anchor 7, and the bolt 13 between the steel backing plates 12 penetrates through the main beam 14, so that the fixing effect is realized. When the cold cast anchor 7 falls off, the sling 1 receives upward tension, the embedded steel pipe 9 generates pressure on the cable end sealing structure 5, and the larger the tension is, the larger the pressure applied to the cable end sealing structure 5 by the embedded steel pipe 9 is, and the larger the anchoring force is.
