Abstract

The invention provides a lifting door plank device capable of being self-locked by use of a single screw. The lifting door plank device comprises a door plank (1) and a door plank lifting driving device (21); the door plank lifting driving device (21) comprises a housing (20) which is fixed on a supporting base; a door plank lifting driving motor (16) is fixed in the housing (20); the door plank lifting driving motor (16) is in power connection with the upper end of a door plank lifting driving lead screw (17); the door plank lifting driving lead screw (17) is in screw-thread fit with a threaded hole formed in the door plank (1); convex shoulders (2) are arranged on the two sides of the upper edge of the door plank (1); locking holes (3) open towards the middle of the door plank (1) and perpendicular to the door plank lifting driving lead screw (17) are formed in the inner side surface of the two convex shoulders (2).

Description

Technical field [0001] The invention belongs to the field of lifting door panels, in particular to a lifting door panel device that uses a single screw to realize automatic locking. Background technique [0002] Some lifting door panels, such as the door panels of breeding workshops and water conservancy gates of livestock farms, are often driven by screw rods to realize the lifting of the door panels, thereby realizing the on-off control of the water flow. [0003] In some occasions, the door panel often needs to be normally open. At this time, the door panel is usually in the elevated position. This has an adverse effect on the force of the lead screw and the stability of the entire door panel system. If the screw rod breaks and other failures occur, it is also easy to cause accidents such as the door panel to fall. [0004] However, some existing locking technologies are often implemented manually, and their reliability and automation are low. And it cannot be locked at any tim...
