Problems solved by technology

[0002] Due to the large size of some hanging object holes (for example: the length is usually 8 meters and the width is more than 3.2 meters); and the special requirements of the lifting operation or the door opening direction is limited, the door panels of the hanging object holes cannot be folded vertically and short-side. , and when the horizontal split is adopted, due to the large span of the door plank, a larger type of steel beam is required to support the self-weight and external load of the door plank, and the conventional split door technology (the door plank and the outer frame are connected by hinges) has a high When it exceeds 1.6 meters, it will not only affect the hoisting sight, but also cause the hanging parts to be unable to be lifted out due to the insufficient lifting height of the lifting equipment.

Abstract

The invention discloses a lifting hole cover plate of an electric turnover structure. The lifting hole cover plate comprises an outer frame, wherein the outer frame is arranged on the periphery of a rectangular lifting hole and is matched with the lifting hole in shape, and the outer frame comprises two opposite short edges and two opposite long edges; guardrails which are the same in structure and can be opened and closed are respectively arranged at the two short edges; movable and turnable door plates with the same structure are respectively arranged at the two long edges; one end of the guardrails is hinged to supports which are arranged on the side walls of the short edges; a plurality of opening and closing driving devices which are used for driving the guardrails to open and close are further arranged in the hinged positions of the guardrails and the supports in the length directions of the guardrails; sliding rails are further arranged on the side walls of the short edges in the length direction, and the sliding rails are located below the supports; and movable driving devices and turnable driving devices are respectively arranged in the middle of the two sides of the back faces of the door plates, and the movable driving devices are located below the turnable driving devices. The cover plate has the advantages of the reasonable structure and convenience in opening and closing, and the overall height is low after the door plates are opened.

Description

technical field [0001] The invention relates to the field of hanging object hole cover plates, in particular to an object hanging object hole cover plate with an electric flip structure. Background technique [0002] Due to the large size of some hanging object holes (for example: the length is usually 8 meters and the width is more than 3.2 meters); and the special requirements of the lifting operation or the door opening direction is limited, the door panel of the hanging object hole cannot adopt the conventional longitudinal short side folding technology , and when the horizontal split is adopted, due to the large span of the door plank, a larger type of steel beam is required to support the self-weight and external load of the door plank, and the conventional split door technology (the door plank and the outer frame are connected by hinges) has a high When it exceeds 1.6 meters, it will not only affect the hoisting sight, but also cause the hanging parts to be unable to ...
