An elevator that prevents the car from moving unintentionally

Abstract

The invention discloses an elevator capable of preventing a car from accidentally moving. The elevator comprises a car guide rail, a car frame, a car assembly, an elevator locking device and a traction host machine; the car frame includes an upper cross beam, a lower cross beam and a stand column; the car assembly includes a car, a car door, and a door opening machine mounted on the stand column or the upper cross beam; the elevator locking device includes an elevator locking plate fixedly connected to the car guide rail and provided with a transverse elevator locking hole, an elevator locking rod base fixedly connected to the two end parts of the upper cross beam and provided with a transverse through hole, an elevator locking rod inserted in the through hole and capable of being inserted in the elevator locking hole, and a drive arranged at the tail end of the elevator locking rod and driving the elevator locking rod to extend and contract front and back; and an anti-slip buckle is arranged at the front end of the elevator locking rod. The elevator locking rod is arranged to penetrate through the through hole of the elevator locking rod base and to be inserted in the reserved elevator locking hole of the elevator locking plate; an anti-falling structure is added to promote the fixed-point stop and door opening safety of the elevator; and the anti-slip buckle penetrates through the elevator locking hole to prevent the elevator locking rod from slipping, so that longitudinal displacement in opening of the car door is prevented and absolute brake is achieved.

Description

technical field [0001] The present invention relates to an elevator, and more particularly to an elevator capable of preventing unintentional movement of the car. Background technique [0002] At present, there are frequent incidents of casualties caused by elevator accidents. When the elevator car is running normally to the leveling floor of the door area and the door is opened, if the main engine brake is worn, improper maintenance or other reasons fail, it cannot be completely stopped. The main engine, or because the wire rope slipped, the wire rope was broken, or even the safety gear-speed governor linkage failed to stop, that is, the safety gear brake failed and other reasons, resulting in the elevator car still going upwards when the door is opened. Running or running downwards, at this time, if people enter and exit in the gate area, major casualties will inevitably occur. In view of this, in view of the above-mentioned situation, it is necessary to specially develop...
