Description
Technical Field
The utility model relates to the technical field of opening and closing of protective doors, in particular to a protective hangar door traveling device capable of adapting to track gradient.
Background
The protective hangar door is an ultra-wide heavy door. The ultra-wide means that the width of a single door leaf of the door type is more than 5 meters and the height is more than 5 meters; by heavy is meant that the individual door leaves weigh more than 30 tons. The flat-open type heavy door leaf is like a cantilever beam structure, and when the door leaf is opened and closed at ordinary times, the door frame wall is stressed in a heavy load multidirectional manner; if the door leaf is impacted, the hinge bears huge impact load under the dual actions of negative pressure and door leaf vibration due to the impact wave effect, and once the constraint point fails, the door leaf overturns, so that not only is the indoor protection ineffective, but also serious secondary disasters are caused.
Therefore, in order to meet the performance index of the ultra-wide heavy protective door, the running mechanism is arranged on the non-hinge side of the lower part of the door leaf, which is close to the side of the door, and when the door body normally operates, the track of the ground running wheel and the running mechanism form a pair of acting force and reacting force. The hinge and the travelling wheels are stressed simultaneously, so that the door leaf has more stable conditions during operation, and the stress of the hinge on the door frame wall is reduced.
However, the ground level in some areas has a gradient and the door leaves are overweight, so that the door body or the building body has a risk point of integral settlement, and the existing travelling mechanism does not have the function of automatically adjusting the gradient relative to the track.
