Description

A kind of elevator hand-pulling door outbound call control device

technical field

The utility model relates to an outbound call control device for an elevator hand-pulled door.

Background technique

With the rapid development of the economy, the demand for home elevators in my country has increased greatly. Villa elevators and lifting platform equipment have always adopted automatic door technology. Due to the inconvenience of space, home elevators use the same door knife as ordinary passenger elevators to drive the door ball to open the hall door. Therefore, Basically, a set of automatic door control system is used on each floor, so the failure rate is high, so the hand-pulling door came into being. Handle door control has become the key to villa elevators and lifting platforms. Generally, the elevator main board is used to directly control the retraction of the handle door electromagnet. The handle door can be opened, but the wiring is more complicated.

The elevator automatic door of the ordinary passenger elevator is that the elevator main board sends the door opening and closing command to the door operator controller through CAN or switch value. The door operator controller drives the motor to drive the belt. The knife clamps the hall door ball and drives the door ball to move, thereby driving the hall door to open and close. The manual doors used in villa elevators and lifting platforms are only hall doors, not sedan doors. There is no way to drive the door kick through the door knife. The traditional method is to use hand-pull doors for hall doors, and each floor's hand-pull doors have a set of automatic door opening devices. , the control is complex and prone to failure.

Please refer to Figure 1. In a traditional home villa elevator, each landing is provided with an outbound call control panel 2', and the hand-pull door of each landing uses an electromagnet 3' to control the latch. Set the electromagnet control board 4' that controls the pull-in and release of the pull-door electromagnet. All the electromagnet control boards 4' are connected to the output pins Y80-Y8n of the elevator main board 1' in one-to-one correspondence. The floor sensor 5' is connected to the pin X60 of the elevator main board 1', and the leveling sensor 5' is used for floor counting; each outbound call control board 2' communicates with the elevator main board 1' through the CAN bus. Only through the elevator main board 1' to control the pull-in and release of the hand-pulling door electromagnet to realize the control of the opponent's sliding door. After the electromagnet is pulled in, the electromagnet drives the lock tongue to retract. When the door is closed, the passenger can push the door to open and close the door. Once the door is closed, the system detects that the door lock is closed and the electromagnet is released, and the latch pops out to lock the door. The traditional method is to control the hand-pulling door electromagnet of each floor station through the multiple output pins Y80-Y8n of the elevator main board. Therefore, if you need to increase the output pins as the control of the added hall door, it is generally necessary to re-develop the elevator. The motherboard is time-consuming and labor-intensive.

At the same time, traditional home villa elevators use the leveling sensor 5' on the car top to calculate the floor. This is a relative position sensor to determine the location of the elevator. Once the leveling sensor 5' has signal jitter or other reasons, the floor may be wrong. Ordinary elevator hall doors are controlled by the car door. The hall door will be locked by gravity after the car leaves, which will not cause danger, but the hand-pulled door may be dangerous. For example, the car is actually on the 3rd floor, and the leveling sensor 5' calculates The first floor is the 2nd floor. At this time, the main board of the elevator controls the pull-in of the electromagnet of the hand-pull door on the 2nd floor, so there is a split floor, and then there is a possibility that the passengers will open the hand-pull door and fall directly into the hoistway due to the split floor.
