Multiple-overlapping anti-derailment balance hangar door

Abstract

The invention discloses a multiple-overlapping anti-derailment balance hangar door. The hangar door comprises a plurality of lower rails arranged in parallel, a door leaf is arranged on each lower rail in a rolling way, balance clamping wheels and anti-derailment devices are arranged on shells of road wheels, a plurality of upper rails are arranged above the plurality of lower rails in parallel, each lower rail is corresponding to a gap between every two adjacent upper rails, two guide wheels are arranged on the top of each door leaf, and the guide wheels are located between the two adjacent upper rails; overturn-preventing devices are also arranged on the tops of the door leaves, and are located between the two adjacent upper rails in the same way; a traction device is separately arrangedon two sides of each door leaf, the two adjacent door leaves move by traction through the traction devices between the two adjacent door leaves, the door leaf located on the innermost side of a dooropening among the plurality of mutually parallel door leaves is a driving door leaf, a driving motor drives the driving door leaf to walk, and the driving door leaf drives the rest door leaves to walkthrough the traction devices. The multiple-overlapping anti-derailment balance hangar door disclosed by the invention meets the requirements of a hangar door for high safety, high reliability and high stability.

Description

technical field [0001] The invention relates to a multi-overlap anti-derailing balanced hangar door, which belongs to the technical field of hangar doors. Background technique [0002] At present, more and more hangars are born in our country, and the number of hangar doors also increases. However, in harsh environments, such as when the wind load is large, the traditional hangar door skeleton structure can withstand wind pressure, but the upper guide wheel is weak. There are no other protective measures, and the safety performance is low; when the door leaf stops suddenly, there is inertia. If the wind pressure direction is consistent with the load direction, the door leaf is likely to derail; the hangar door opening is large, and most traditional hangar doors use multi-overlapping. Setting, independent drive, many lines, high failure rate; therefore, it is necessary to design a new type of hangar door that is safer, more reliable and more stable to solve the above problems...
