Description

Technical Field

[0001] The utility model relates to the technical field of hangar doors, in particular to a hangar door single-node bolt connection mechanism and the hangar door. Background Art

[0002] The hangar door is the main door of the hangar for aircraft to pass through. It is a kind of airport ground support equipment. The hangar is a building for aircraft to stay and maintain. The installation of a hangar door can shield and protect the interior of the hangar.

[0003] The main structure of existing hangar doors is divided into two forms:

[0004] One is the on-site welding type, in which the steel sections used for the hangar door are transported to the project site, welded into the main structure on site, and then the power unit, auxiliary unit and decorative parts are added to form a complete hangar door.

[0005] Among them, the power unit is a general term for devices that provide power for the main structure, which can be pneumatic, electric and internal combustion engines and their driven wheel sets; the auxiliary unit is a general term for various systems that enable all equipment on the main structure to work normally, including wires, sensors, locks, communication systems and control systems; decorative parts are a general term for other structures that do not affect the functions of the equipment on the main structure, including glass, panels, frame panels and seals.

[0006] Due to the huge structure of the hangar door, there are many connection nodes between the various profiles, and there are a large number of complex welding points, which cannot be automated. Manual welding is labor-intensive, inefficient, and has poor precision, resulting in long construction periods and unstable project quality.

[0007] The other is the bolt assembly type, in which the installation holes are processed in the factory for the steel sections used for the hangar door, and then the various sections are assembled into the main structure with bolts at the construction site, and then the power unit, auxiliary unit and decorative parts are added to form a complete hangar door.

[0008] This method avoids on-site welding and improves on-site construction efficiency. However, since the main structure of the hangar door is generally provided with an anti-rust coating on the surface, when bolts are used for on-site assembly, the anti-rust coating will be partially worn away due to surface rotation and extrusion at the joint, thereby losing the anti-rust effect. Utility Model Content

[0009] The utility model aims to overcome the deficiencies of the prior art and provide a hangar door single-node bolt connection mechanism and hangar door thereof, so as to solve the technical problem that the anti-rust coating of the existing hangar door assembled by bolts is easily worn.

[0010] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] An embodiment of the utility model provides a single-node bolt connection mechanism for a hangar door, which includes: a first structure, a second structure, a bolt assembly and a sleeve assembly; the first structure and the second structure are both provided with connection holes, and the surfaces are provided with a coating, the sleeve assembly is inserted into the connection hole, and the bolt assembly passes through the sleeve assembly to connect and fix the first structure and the second structure.

[0012] Wherein, the sleeve assembly comprises: an upper sleeve and a lower sleeve with the same structure, and the upper sleeve and the lower sleeve are reversely butt-jointed with each other and arranged in the connecting hole.

[0013] Wherein, the upper sleeve and the lower sleeve both include: a tube body and an annular platform vertically protruding from one end edge of the tube body, and the ends of the upper sleeve and the lower sleeve away from the annular platform are butt-jointed.

[0014] Wherein, an annular groove is further provided at the opening of the connecting hole, and the annular platform is sunk in the annular groove.

[0015] Wherein, the sleeve assembly is welded to the hole wall of the connecting hole.

[0016] Wherein, the bolt assembly comprises: a hole-making bolt and a nut screwed on the hole-making bolt.

[0017] The embodiment of the utility model further provides a hangar door, which comprises a plurality of door body units connected and fixed by the hangar door single-node bolt connection mechanism as described in any one of the above items.

[0018] The hangar door single-node bolt connection mechanism and hangar door of the utility model adopt a bolt assembly and a sleeve assembly to connect and fix a first structure body and a second structure body that are butted together. The sleeve assembly separates the bolt from the structure body, thereby avoiding the bolt assembly from wearing the surface of the structure body during assembly, thereby protecting the protective coating.

[0031] Please see attached Figures 1 to 4 The present embodiment provides a hangar door single-node bolt connection mechanism 100, which includes: a first structure 10, a second structure 20, a bolt assembly 1 and a sleeve assembly 2; the first structure 10 and the second structure 20 are both provided with a connection hole 40, and the surface is provided with a coating 30, the first structure 10 and the second structure 20 can be made of non-rustproof steel with higher strength, the sleeve assembly 2 is inserted into the connection hole 40, and the bolt assembly 1 passes through the sleeve assembly 2 so as to connect and fix the first structure 10 and the second structure 20. Among them, the first structure 10 and the second structure 20 are both single profiles constituting the main structure of the hangar door. The sleeve assembly 2 is made of stainless steel, and there is no need to spray an anti-rust layer on its surface.

[0032] The sleeve assembly 2 includes an upper sleeve 21 and a lower sleeve 22 of the same structure, and the upper sleeve 21 and the lower sleeve 22 are oppositely connected to each other and arranged in the connecting hole 40. In this embodiment, the connecting hole 40 is a through hole opened on the first structure 10 and the second structure 20.
