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...

Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Such as Figure 1-13As shown: this embodiment is a multi-overlap anti-derailment balanced hangar door, including five lower rails 3 arranged in parallel, and a door leaf 1 is arranged on each lower rail 3, and the five door leaves 1 are parallel to each other. Two road wheels 5 are arranged at the bottom, and the door leaf 1 rolls on the lower track 3 through the two road wheels 5. The housing of the road wheels 5 is provided with a balance clamp wheel 12 and an anti-derailment device 15. There are two balance clamp wheels 12, The two balance clamp wheels 12 are respectively located on both sides of the lower rail 3 and are in rolling contact with the walls on both sides of the lower rail 3. The anti-derailment device 15 is two L-shaped steel plates, and the two L-shaped steel plates are located symmetrically on both sides of the lower rail 3; ...
