Description

Elevator double-cutter-head assembly with limiting function

Technical Field

The application relates to the technical field of elevator equipment, concretely relates to elevator double knives door subassembly with limit function.

Background

The elevator is used as a vertical transportation tool, the usage amount of the elevator in buildings such as high-rise houses, business hotels, office buildings, shopping malls and the like is more and more, the daily use frequency of the elevator is different according to the occasions where the elevator is located, and accidents caused by improper equipment or manual operation methods occur occasionally along with the popularization and the use of the elevator, particularly door system problems account for about 80 percent of the accidents of the elevator.

The elevator door vane device is a mechanism responsible for opening and closing elevator hall doors, is generally in a strip shape, so the elevator door vane device is called as a door vane in an image, and the elevator door vane is one of indispensable parts of modern elevators. When the elevator door knife works, the two knife arms are combined, and the opening of the hall door is controlled after the elevator door knife contacts the door ball.

However, the conventional elevator door vane device has the following defects: because traditional door sword subassembly uses the linkage board to carry out centre gripping simultaneously to two door knives, consequently the not hard up probability of structure is higher when using for a long time, leads to the centre gripping unstability to elevator door ball easily, and the structural design of linkage board can lead to two door knives dislocation in addition, leads to the centre gripping area, takes place the problem that elevator door ball breaks away from more easily after not hard up.

Disclosure of Invention

An aim at of this application provides a structural strength is high, is difficult not hard up, more stable elevator double knives door subassembly that has limit function during the centre gripping.

In order to achieve the above purposes, the technical scheme adopted by the application is as follows: an elevator double-knife door assembly with a limiting function comprises a bottom plate, a fixed door knife, a movable door knife, a driver and a driving motor, wherein the fixed door knife is fixedly arranged on one side of the bottom plate, the movable door knife is transversely slidably arranged on the other side of the bottom plate, the driver is rotatably arranged on the bottom plate, a connecting rod is arranged at the non-rotating circle center of the driver, a longitudinal sliding groove is formed in the movable door knife, the connecting rod is slidably connected in the sliding groove, and when the driving motor controls the driver to rotate, the movable door knife can transversely slide along with the driver and is matched with the fixed door knife to clamp an elevator door ball; the fixed door knife is rotatably provided with a locking piece, and when the movable door knife slides to the position closest to the fixed door knife, the driving motor can control the locking piece to be matched and locked with the driver.

Specifically, the driver includes the driving-disc, the outside arch of edge of driving-disc forms joint portion, the locking piece can with joint portion cooperation joint.

As an improvement, a locking opening is formed in the fixed door knife, the locking piece is arranged in the locking opening, and the driver can extend into the locking opening to be matched and locked with the locking piece.

As an improvement, clamping walls are arranged on the fixed door knife and the movable door knife, and the clamping walls are matched with each other to form a clamping guide rail.

As an improvement, the rotation circle centers of the clamping part, the connecting rod and the driver are positioned on the same straight line.

As an improvement, the locking piece includes the locking hook, joint portion one side is inwards sunken to form the joint groove, the locking hook can cooperate the joint extremely in the joint groove.

As an improvement, the two ends of the clamping guide rail are flared outwards to form a guide part.

Compared with the prior art, the beneficial effect of this application lies in: the linkage clamping structure of the two door knives is changed into the movable structure of the single door knife, in order to ensure the structural strength of the movable door knife, the movable door knife is eccentrically connected with the driver, the sliding of the movable door knife is controlled by the rotation of the driver, and the reaction force of an elevator door ball to the movable door knife during clamping cannot enable the movable door knife to rotate to cause looseness of the movable door knife, so that the clamping stability is higher; in addition, in order to reduce the pressure of reaction force to the driver, set up joint portion on the driver, the driver can lock with the locking piece on the fixed door sword when the centre gripping of dodge gate sword, further increases clamping stability, increases life, avoids unexpected emergence.
