AI Technical Summary
When connecting existing seismic hinges to heavy-duty pipelines, the connection relationship between the components is relatively weak, which can easily lead to loosening and pose safety hazards.
The first and second connecting ends that are hinged and cooperate with each other are provided with threaded holes and screw connections through an integrated molded connecting plate and hollow tubular structure to ensure the symmetry and coordinated load bearing of the two components.
The connecting bearing capacity between the hanging boom channel steel and the oblique brace channel steel is improved to ensure safety and integrity and avoid loosening problems.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of hinged connectors, in particular to a heavy-duty pipeline high-bearing capacity earthquake-resistant hinge. Background Art
[0002] As the connecting parts of steel structures, hinged connectors play a very important role in the entire structure. The existing seismic support and hanger brackets, the support connections between the cross arm channel steel and the hanger channel steel, are not matched with the actual force in terms of bearing capacity. For large gravity pipelines, it is required to adopt the connection method of through bolts, and adopt different numbers of spiral connections according to the actual weight of the gravity pipeline. At the same time, the stability of the support connection between the cross arm channel steel and the hanger channel steel must be ensured. The traditional connection method is only a single-sided connection, and there is no way to achieve force symmetry and coordination.
[0003] The utility model patent with Chinese patent application number 201921772722.3 discloses an anti-seismic support and hanger hinge, including a first connecting plate, a second connecting plate, a fixing hole and a buffer unit; the first connecting plate: the upper surface of the first connecting plate has two connecting holes, the right end of the upper surface of the first connecting plate is correspondingly provided with a first inclined plate, the first inclined plate is perpendicular to the first connecting plate, the right end of the first inclined plate is provided with a first fixing plate, and the first fixing plate is perpendicular to the first connecting plate; the second connecting plate: the second connecting plate is opposite to the first connecting plate, the upper surface of the second connecting plate is correspondingly provided with a right-angle through groove, the front end of the right-angle through groove extends to the outside of the second connecting plate, the left end of the upper surface of the second connecting plate is provided with a second inclined plate, and the second inclined plate is perpendicular to the second connecting plate. The anti-seismic support and hanger hinge has a good buffering effect, is not easy to loosen, and is easy to fix and install, which brings convenience to installation and use. However, the technical solution proposed in the above utility model still belongs to a one-sided fitting connection for the connection method of the two side components, which is easy to loosen during connection and use. Utility Model Content
[0004] Therefore, based on the above technical problems, the utility model proposes a heavy-duty pipeline high-load-bearing anti-seismic hinge, which solves the technical problem that the connection between the existing anti-seismic hinge and the components is relatively weak, and it is easy to loosen after long-term use, causing safety hazards.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a heavy-duty pipeline high-load-bearing capacity earthquake-resistant hinge, comprising a first connecting end and a second connecting end that are hingedly matched with each other, the first connecting end comprising an integrally formed first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are twisted with each other so that the two plate surfaces are perpendicular to each other, a first threaded hole is provided on the first connecting plate, a second threaded hole is provided on the second connecting plate, and the second connecting end is a hollow tubular structure.
[0006] Furthermore, the second connecting end is a hollow square tubular structure, a third connecting plate is provided on the second connecting end, a third threaded hole is provided on the third connecting plate, the third connecting plate and the second connecting plate are fitted together, the third threaded hole and the second threaded hole are interconnected and screwed together by screws.
[0007] Furthermore, a fourth threaded hole is provided on the second connecting end. The fourth threaded hole is provided on the outer side wall of the second connecting end and passes through the inner cavity of the second connecting end.
[0008] Furthermore, the fourth threaded hole is arranged on a single outer side wall of the second connecting end or on both opposite side walls.
[0009] By adopting the above technical solution, the beneficial effects of the utility model are:
[0010] The utility model improves the structure of the first connecting end and the second connecting end on the connecting piece, which can improve the connection method between the hanger channel steel and the diagonal brace channel steel compared to the traditional hinged structure, so that the bearing capacity of the two components after connection is improved and can match the corresponding bearing capacity, further ensuring safety and integrity.
