Abstract

The invention discloses a composite locking elevator hoistway door interlock device. The device consists of a part 1, namely an upper locking rod, a part 2, namely a linkage fixing plate, a part 3, namely a fixing frame, a part 4, namely a linkage clamping plate, a part 5, namely a well switch turning-on plate, a part 6, namely a linkage plate, and a part 7, namely a special-shaped butterfly spring, wherein the fixing frame is arranged on the upper side of the upper plane of a movable locking fixing plate, which is close to a top angle; the upper locking rod passes through rectangular holes in the left and right sides of the fixing frame from rear to front; a sliding shaft is arranged on the right-angle bent plane of the other end of the upper locking rod; one foot of the special-shaped butterfly spring is arranged on the sliding shaft, and the other foot of the special-shaped butterfly spring is arranged on the movable locking fixing plate; the sliding shaft is arranged in a long slot above the plane of the movable locking fixing plate; the linkage fixing plate is arranged below the plane of the movable locking fixing plate; the linkage clamping plate is arranged on the middle part of the linkage fixing plate; the linkage plate is arranged on the plane of the lower part of the linkage fixing plate; and the well switch turning-on plate is arranged on the plane of a fixing locking block fixing plate.

Description

technology field; [0001] The present invention relates to an elevator hall door interlock, more specifically relates to a composite locking elevator hall door interlock. Background technique; [0002] At present, no matter what kind of vertically running elevator is in normal operation, power failure, maintenance and other occasions, when the user opens the elevator hall door, due to the lack of corresponding safety devices, it often happens that the operator does not look at it in a short period of time. Know the situation in the well and step into the well by mistake, resulting in casualties. Contents of the invention [0003] A fixed frame is fixed on the corner near the top above the plane on the mobile locking fixed plate. A locking rod is inserted into the rectangular holes on the left and right sides of the fixed frame from the back to the front. The other end of the locking rod is bent at a right angle on the plane The sliding shaft is fixed, and one foot ring of ...
