Abstract
The utility model relates to a ball pivot structure guy anchor, which is mainly used for the anchorage of a membrane structure dragline of a stadium or a museum and so on and the utility model consists of a drawbar (2) and a connecting sleeve (3); the connecting sleeve (3) is axially provided with a counterbore (31) in the center, the drawbar (2) passes through the counterbore (31) and the head of the drawbar (2) is arranged at the bottom of the counterbore (31) and is connected with the connecting sleeve (3). The utility model is characterized in that a connecting face between the connecting sleeve (3) and the drawbar (2) is a mutually-matched sphere. The guy anchor of the utility model can not only bear the axial stress of the dragline but also can avoid the occurrence of the additional bending stress of the drawbar after being stressed, which guarantees the normal use of the drawbar.
Description
Technical field
The utility model relates to a kind of dragline anchorage, especially relates to a kind of spherical hinge structure dragline anchorage.Be mainly used in the anchor connection of membrane structure drag-lines such as venue.Belong to the building structural member technical field.
Background technology
Traditional membrane structure drag-lines such as venue with the ground tackle structure as shown in Figure 1.Adopt plane contact to connect between its adapter sleeve 3 and pull bar 2 heads.This connected mode in use can only be born axial force.When drag-line is connected with the membrane structure connector, when the drag-line center does not overlap with membrane structure contact center, when promptly having certain drift angle, can make the stressed back stay of drag-line produce certain bending, the pull bar that causes ground tackle in long-term use owing to bear certain additional bending stress always, influenced the normal use of pull bar, serious meeting causes the bend fracture of ground tackle pull bar.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of axially loaded that can bear drag-line is provided, the spherical hinge structure dragline anchorage that can avoid the stressed back stay additional bending stress of drag-line to produce again.
The purpose of this utility model is achieved in that a kind of spherical hinge structure dragline anchorage, comprise pull bar and adapter sleeve, described adapter sleeve central axis is to being provided with a counterbore, pull bar passes this counterbore, rod head is held on this counterbore bottom and contacts with adapter sleeve and be connected, and it is characterized in that the sphere that the contact surface of described adapter sleeve and pull bar is arranged to cooperatively interact.
The utility model is processed into the hinged sphere of working in coordination by the contact surface with adapter sleeve and pull bar, changed the structure of plane connection between the two in the past, realize low-angle rotation between the two, thereby avoided because drag-line center and membrane structure contact center do not overlap, the generation of the pull bar additional bending stress that causes has guaranteed the normal use of pull bar.
Description of drawings
Fig. 1 is traditional ground tackle structural representation.
Fig. 2 is the general structure schematic diagram of the utility model spherical hinge structure dragline anchorage.
Among the figure: anchor cup 1, pull bar 2, adapter sleeve 3, nut 4.
The specific embodiment
Referring to Fig. 2, the utility model is a kind of spherical hinge structure dragline anchorage, mainly is made up of anchor cup 1, pull bar 2, adapter sleeve 3 and nut 4.Described adapter sleeve 3 central axiss are to being provided with a counterbore 31, spill sphere 32 is arranged in counterbore 31 bottoms, corresponding to this spill sphere 32, pull bar 2 head bottom faces with matching are arranged to convex spherical 21, pull bar 2 passes the counterbore 31 of adapter sleeve 3, and pull bar 2 head rest realize in these counterbore 31 bottoms and adapter sleeve 3 that spheres contact and are connected.Pull bar 2 tail ends are threaded with nut 4.Anchor cup 1 is threaded with the top of adapter sleeve 3 counterbores.
Claims (2)
1. spherical hinge structure dragline anchorage, comprise pull bar (2) and adapter sleeve (3), described adapter sleeve (3) central axis is to being provided with a counterbore (31), pull bar (2) passes this counterbore (31), pull bar (2) head rest contacts with adapter sleeve (3) in this counterbore (31) bottom and is connected, and it is characterized in that the sphere that the contact surface of described adapter sleeve (3) and pull bar (2) is arranged to cooperatively interact.
2. a kind of spherical hinge structure dragline anchorage according to claim 1, spill sphere (32) is arranged in counterbore (31) bottom that it is characterized in that described adapter sleeve (3), corresponding to this spill sphere (32), pull bar with matching (2) head bottom face is arranged to convex spherical (21).
