Door lock device for landing door of elevator and landing door device of elevator

Abstract

The invention discloses a door lock device for a landing door of an elevator and a landing door device of the elevator, and relates to the technical field of elevator accessories. The door lock device comprises a landing door lock body, wherein a control wheel is fixedly installed on the front face of the landing door lock body, a door opening knife is arranged on the right side of the landing door lock body, a door lock maintenance mechanism is arranged on the left side of the landing door lock body, the door lock maintenance mechanism comprises a gooseneck rope, and the left side of the gooseneck rope is fixedly connected with a fixing ring. According to the invention, through a design of a wind power capturing groove, an air flowing force can be captured. Matched with symmetrical plastic paddles, the air flowing force is converted into the force for driving a driving rotating rod to rotate, so that an elastic rope is driven to rotate, and the surface of the landing door lock body is lightly smoothed and dedusted through the door lock contact mechanism; the function of automatically maintaining the surface of the landing door lock body is achieved, and the problem that the service life of the door lock is affected due to the fact that a large amount of dust is prone to being attached to the outer wall of the landing door lock after long-time use is solved.

Description

technical field [0001] The invention relates to the technical field of elevator accessories, in particular to an elevator landing door lock device and an elevator landing door device. Background technique [0002] The landing door lock is installed on the landing door and plays a locking role. It is composed of a lock hook and an electrical safety electric shock. The lock hook acts as a mechanical locking function, and the safety electric shock can disconnect the electrical safety circuit to prevent the elevator from running with the door open. The elevator door is a very important part of the elevator. There are two doors. The one that can be seen from the outside of the elevator and is fixed on each floor is called the landing door, and the one that is seen inside and fixed on the car moves with the car is called the car door. , The switch of the elevator landing door is generally driven by the car door. Its stability, rationality and safety are the key factors that determ...
