Positioning and supporting device for civil air defense door

Abstract

The invention discloses a positioning and supporting device for a civil air defense door. The positioning and supporting device comprises a base, wherein the base comprises a telescopic fixing frame;the telescopic fixing frame is of a rectangular frame structure; four edges of the rectangular frame of the telescopic fixing frame are of telescopic structures; four groups of walking frames are detachably mounted below the telescopic fixing frame; each walking frame comprises a transverse rod and two upright posts; the two upright posts are fixedly connected to two ends of the transverse rod; and two walking wheels are fixedly arranged at the lower ends of the two upright posts. According to the positioning and supporting device, the four edges of the telescopic fixing frame are of the telescopic structures, and can be adjusted according to the size of a door frame of the civil air defense door, so that the frame edge of the civil air defense door is conveniently fixed, and an operator conveniently welds the civil air defense door; and when the positioning and supporting device is used, the frame of the civil air defense door is placed on a supporting plate, the supporting plate is used for supporting the frame of the civil air defense door, and a movable sliding block can slide on the supporting plate to adjust the fixed position, so that welding is facilitated.

Description

technical field [0001] The invention relates to the technical field of air defense doors, in particular to a positioning support device for air defense doors. Background technique [0002] The civil air defense door is the door of the entrance and exit of the civil protection project. The classification of the civil air defense door is relatively clear. There are ordinary single and double protective airtight doors and airtight doors, and a variety of civil air defense equipment such as single and double protective airtight doors and airtight doors with living thresholds. The door frame of the air defense door generally needs to be welded by combining four frame edges together. In the prior art, the operator generally presses the door frame with his hands for welding, which can easily cause the welding of the door frame to be misaligned. situation, for this reason we propose a positioning support device for air defense doors in order to solve the above problems.
