Abstract
The invention discloses a light curtain safety protection elevator door. The light curtain safety protection elevator door comprises a car door and a hoistway door, wherein a limiting plate is arranged on the inner edge line of the opening side surface of the hoistway door, the rotatable limiting plate is arranged on the opening side surface of the hoistway door, the limiting plate is mounted on the hoistway door through a rotating shaft in a vertical direction, and the limiting plate can rotate around the rotating shaft. When the hoistway door and the car door are opened, the limiting plate can rotate towards the car door and is clamped at the part of a car door opening. When the hoistway door and the car door are closed, the limiting plate can rotate towards the outer side of the hoistway door until clings to the hoistway door. A transmitting unit and a receiving unit of a light curtain protection device are separately mounted at the upper guide rail part and the lower threshold part of the car door. The light curtain safety protection elevator door provided by the invention can limit an elevator lift car in the process that passengers get on/off an elevator on an elevator stop floor layer, is high in safety and is firm and reliable.
Description
Technical field
The present invention relates to a kind of light curtain Safety-protection elevator door, belong to vertical lift field.
Background technology
Elevator is indispensable instrument in the modern life, and security system is part critically important in elevator device, is used for
Ensure that elevator safety uses, prevent all from jeopardizing the accident of personal safety and occur, but in current existing elevator accident, have one
Situation is when elevator rests on flat bed, and during passenger passes in and out elevator, elevator occurs the most suddenly exception
Move up or down, make to cause passenger to be sandwiched between gate and the hall door of flat bed, serious security incident occur.
Summary of the invention
The technical problem to be solved is to provide a kind of light curtain Safety-protection elevator door, can prevent elevator door from closing
The abnormal elevator of front generation moves, and passes in and out elevator with making passenger safety.
For solving above technical problem, the technical solution used in the present invention is: a kind of light curtain Safety-protection elevator door, including
Gate and hall door, the inside edge line of described hall door open side is provided with one piece of limiting plate, the open side of described hall door
On be provided with rotatable limiting plate, described limiting plate is installed in hall door by the rotating shaft of vertical direction, and described limiting plate can
Rotating around the shaft, when hall door and gate are opened, described limiting plate can rotate to gate direction and be stuck in gate opening part, works as the Room
Door and gate close time, described limiting plate can rotate until being close to hall door outside hall door, at the overlying guide rail of described gate with
It is separately installed with the transmitter unit of light curtain protection device at the threshold of lower section and receives unit.
Described rotating shaft is connected with motor, and described motor is connected with elevator control circuit.
Described limiting plate upper and lower side is 0.5-2cm with the distance of the upper and lower side of elevator entrance.
Described hall door and gate are the simple gate opened to side.
Described hall door and gate be centre open two-door, the described hall door of both sides is provided with limiting plate.
Described limiting plate uses carbon steel material.
The using method of the present invention is:
After elevator rests on flat bed, elevator cage door and hall door are opened simultaneously, then limiting plate rotates to gate side, is stuck in gate and enters
At Kou, and moving with elevator cage door and hall door, until elevator door fully opens, the upper and lower elevator of passenger subsequently, in this process simultaneously
In, limiting plate can stop the elevator caused because of abnormal elevator to move up and down, and prevents from crushing passenger；When passenger completes upper and lower elevator
After, elevator is gradually closed the door, and before elevator door completely closes, limiting plate rotates outside hall door, until with hall door open side
Laminating, hoistway door and gate completely close subsequently.
The beneficial effects of the present invention is:
Light curtain protection device protection device achieves and prevents elevator door from crushing passenger, and limiting plate achieves the limit to lift car
Position so that it is cannot move up and down, it is ensured that passenger's safety when passing in and out elevator；Limiting plate is fixed in hall door so that it is fulcrum
After the firmest, relative to being fixed on gate or safety edge, fastness is higher, and elevator door cuts out, limiting plate is to hall door
Side is packed up, as long as limiting plate departs from gate entrance scope, even if putting in place the most completely, also the operation of elevator will not be produced impact.
Therefore, a kind of light curtain Safety-protection elevator door provided by the present invention, it is possible to stop flat bed passenger at elevator upper and lower
Carrying out spacing to lift car during elevator, safety is high, solid and reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation that the limiting plate of the present invention is opened；
Fig. 3 is the structural representation that the limiting plate of the present invention is packed up.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating the present invention
Technical scheme, and can not limit the scope of the invention with this.
A kind of light curtain Safety-protection elevator door as shown in Figures 1 to 3, including gate 1 and hall door 2, described hall door 2 open side
It is provided with one piece of limiting plate 3 on the inside edge line in face, the open side of described hall door 2 is provided with one piece of limiting plate 3, described
Limiting plate 3 is installed in hall door 2 by the rotating shaft 4 of vertical direction, and described limiting plate 3 can 4 rotate, when hall door 2 and sedan-chair around the shaft
When door 1 is opened, described limiting plate 3 can rotate to gate 1 direction and be stuck in gate 1 opening part, when hall door 2 and gate 1 are closed,
Described limiting plate 3 can rotate until being close to hall door 2 outside hall door 2, punishes with lower section threshold at the overlying guide rail of described gate 1
The transmitter unit of light curtain protection device is not installed and receives unit.
Described rotating shaft 4 is connected with motor, and described motor is connected with elevator control circuit.
Described limiting plate 3 upper and lower side is 2cm with the distance of the upper and lower side of elevator entrance.
Described hall door 2 and gate 1 are the simple gate opened to side.
Described limiting plate 3 uses carbon steel material.
The using method of the present invention is:
After elevator rests on flat bed, elevator cage door 1 and hall door 2 are opened simultaneously, then limiting plate 3 rotates to gate 1 side, is stuck in sedan-chair
Door 1 porch, and move with elevator cage door 1 and hall door 2, until elevator door fully opens, the upper and lower elevator of passenger subsequently, simultaneously
During this, limiting plate 3 can stop the elevator caused because of abnormal elevator to move up and down, and prevents from crushing passenger；When passenger completes
Up and down after elevator, elevator is gradually closed the door, and before elevator door completely closes, limiting plate 3 rotates outside hall door 2, until and the Room
