Description

Technical Field

[0001] The utility model belongs to the technical field of bridge hanger construction, in particular to a bridge hanger lifting device. Background Art

[0002] With the rapid development of transportation construction in my country, cable bridges such as arch bridges, cable-stayed bridges, and suspension bridges have been widely used as large bridges in the past three decades, and the number of such bridges is still growing. The hanger is the main load-bearing component of the beam-arch composite bridge, and it is also the main way to transfer the deadweight of the main beam, the load of auxiliary facilities, and the live load to the arch rib. When the bridge hanger reaches its design service life, it needs to be replaced. However, during the replacement stage of the current bridge hanger, the bridge hanger needs to be lifted. During the lifting process, there is no suitable sling binding position on the bridge hanger, which is easy to slip, and the safety performance is not enough. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a bridge hanger lifting device which is not easy to slip and has good safety.

[0004] The purpose of the utility model is achieved through the following technical scheme. The bridge hanger lifting device includes a bridge hanger and a lifting rope unit. An anchor head unit is provided on one end of the bridge hanger. A circle of binding ring is fixedly installed on the circumferential wall of the anchor head unit, and the lifting rope unit is bound to the binding ring. A lifting ear is fixedly installed at the center position of an axial side surface of the anchor head unit, and a rope is bound to the lifting ear. When the bridge hanger is lifted, the lifting rope unit and the rope are both hung on the hook of the crane.

[0005] The beneficial effects of the utility model are as follows: compared with the prior art, by arranging a binding ring on the circumferential wall of the anchor head unit and installing a fixed lifting ear on the axial side, when the bridge hanger is lifted, the entire bridge hanger is hung on the hook of the crane through a double sling, which has the advantages of not easy to slip during lifting and good safety.

[0006] Preferably, the anchor head unit includes a connecting tube and an anchor head, one end of the connecting tube is installed and fixed on the end of the hanger cable body of the bridge hanger, and the anchor head is installed and fixed on the other end of the connecting tube, and the binding ring is welded and fixed on the circumferential wall of the connecting tube, and the lifting ear is welded and fixed on the center position of the axial side of the anchor head; through the arrangement of the above structure, the binding ring and the lifting ear are arranged on the rigid component of the bridge hanger, so that the stability and safety of the bridge hanger during the lifting process are better.

[0007] Preferably, the binding ring is provided with an anti-slip strip distributed in a threaded shape; by providing this threaded anti-slip strip, after the sling and the binding ring are bound and fixed, when lifting, the sling and the binding ring will be almost parallel, so the anti-slip strip of this structure can greatly increase the friction between the sling and the binding ring, and the anti-slip performance is better.

[0008] Preferably, the lifting rope unit includes a sling and a lifting wire rope, one end of the sling is connected and fixed to one end of a rotating hook body, one end of the lifting wire rope is connected and fixed to the other end of the rotating hook body, and the other end of the sling is tied to the tying ring, and the other end of the lifting wire rope is hung on the hook of the crane; through the arrangement of the above-mentioned structure, the sling and the tying ring are better tied firmly and have better anti-slip performance, and the binding of the lifting wire rope and the tying ring can be avoided. Through the rotating hook body, the alignment and insertion between the bridge hanger and the bridge rib arch after lifting are facilitated.

[0009] Preferably, the rotating hook body includes a hook body and a rod body, and insertion holes are provided on both side walls of the hook body. The rod body is inserted into and limited on the insertion holes. One end of the rod body is provided with a limit block and is limited with one of the insertion holes, and the other end of the rod body is provided with a thread and is fixed to the other insertion hole by a nut. Through the arrangement of the above structure, the installation between the rotating hook body and the sling and the lifting wire rope is more convenient and the structure is simpler.

[0010] Preferably, the hook body is a U-shaped structure; this allows the lifting wire rope and the lifting belt to be more evenly stressed during the lifting process of the bridge boom, greatly improving stability. BRIEF DESCRIPTION OF THE DRAWINGS
