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 lift-type door panels, in particular to a lift-type door-panel device that uses a single screw rod to realize automatic locking. Background technique [0002] Some lift-type door panels, such as the door panels of the breeding workshop of livestock farms, water conservancy gates, etc., are often driven by screw rods to realize the lifting of the door panels, and then realize the on-off control of water flow. [0003] In some occasions, the door panel often needs to be opened normally, and at this time, the door panel is often in the lifting position normally. This has an adverse effect on the stress of the lead screw and the stability of the entire door panel system. If failures such as screw rod breakage occur, it is also easy to cause accidents such as door panel falling. [0004] However, some existing locking technologies are often implemented manually, and their reliability and degree of automation are relat...
