The present invention relates to a door and safety door automatic opening and closing system of a construction site lift capable of emergency opening to prevent unsafe safety accidents.

In general, a construction site lift is a device for easily delivering and transporting workers and lightweight materials to each floor when building a high-rise building such as an apartment, and the cage is driven along a mast installed vertically on an outer wall that can easily enter and exit each floor. It is comprised so that it may move to each floor by a motor.

At this time, each floor is equipped with a safety door that detects the arrival of the cage through the infrared sensor to automatically open and close horizontally by the drive motor.

Therefore, when the cage arrives on any floor as the cage descends along the mast, the safety door installed on the arbitrary floor is automatically opened, and the safety door on any floor before the cage leaves the floor. This will close automatically.

And the entrance door of the cage is configured to be opened and closed only when the cage reaches each floor by the locking device to stop, which is a structure that can be opened and closed by a manual method.

Accordingly, when the cage arrives at an arbitrary floor by the driver's request for driving, the door is manually opened while the safety door is automatically opened.

Such a conventional construction site lift has a strong force to forcibly open the door of the cage and the safety door of each floor when a malfunction occurs during operation and the cage stops abnormally between floors or floors. Could not be opened easily.

Therefore, the occupant cannot escape quickly from the cage, and cannot secure the occupant's safety from a safety accident such as a fall of the cage.

The present invention has been invented to solve the above problems, even when the operation is stopped due to the malfunction of the lift to easily open the door of the cage and the safety doors of each floor so that the occupant quickly escapes from the cage of the cage In order to ensure the safety of the occupants from safety accidents such as falls, the doors and safety of the construction site lift that can be opened automatically by forcibly opening the doors of Keezie and the safety doors on each floor for a set time. The purpose is to provide a professional automatic switching system.

One transmitting and receiving unit 40a; Cage detection sensor 11b for transmitting the cage signal to detect the position of the cage (C) and the door detection sensor 12b for detecting the opening and closing state of the door (D) to generate the door state signal A second detection unit 10b composed of; The signal processing unit 21b and the driving motor M2 for receiving a cage attachment signal of the cage detection sensor 11b and a gate opening / closing signal of the door detection sensor 12b to generate a motor driving signal for driving the driving motor M2. A second control unit 20b composed of a power supply unit 22b for guiding a direct current power source for driving the < RTI ID = 0.0 > A second driving unit 30b receiving the motor driving signal of the signal processing unit 21b and supplying the power of the power supply unit 22b to the driving motor M2; The door door open signal or the door closed signal to the receiver 42b for receiving the safety door open signal or the safety door closed signal from the transmitter 41a of the first transmitter / receiver 40a and the receiver 42a of the first transmitter / receiver 40a. To a second transmitter / receiver 40b comprising a transmitter 41b for transmitting a signal; In the automatic opening and closing door and safety door opening and closing system of the construction site lift configured, the first driving unit 30a and the second driving unit 30b to sense the voltage increase of both ends of the drive motor M1 and the drive motor M2, respectively A voltage sensing unit 31a and a voltage sensing unit 31b for generating a detection signal are provided, and the voltage sensing unit 31a and the voltage sensing unit 31b are respectively provided in the first control unit 20a and the second control unit 20b. The emergency opening control unit 23a and the emergency opening control unit 23b for driving the driving motor M1 and the driving motor M2 by receiving the detection signal of the present invention are installed.

The door and safety door automatic opening and closing system of the construction site lift equipped with the emergency opening device of the present invention configured as described above is used when the cage C stops abnormally due to a malfunction during the operation of the lift L shown in FIG. 1. It is a device that can open the door (D) and the safety door (S) of each floor forcibly.

2 to 4 detects the voltage increase occurring at both ends of the driving motor M1 for opening and closing the safety door S and the driving motor M2 for opening and closing the door D. The voltage sensing unit 31a and the voltage sensing unit 31b are installed, and the driving motor M1 and the driving motor M2 are formed through voltage intensification detected by the voltage sensing unit 31a and the voltage sensing unit 31b. This is because the emergency opening control unit 23a and the emergency opening control unit 23b are installed to explain the operation of the emergency opening control unit 23a and 23b.

As shown in FIG. 5, when the cage C descending along the mast M suddenly stops between layers or layers due to an abnormal operation of the lift L due to a malfunction, the cage C The door D and the safety door S on each floor are in a closed state.

At this time, if a force is applied for a predetermined time to forcibly open the safety door (S) and the door (D) in order to escape from the cage (C), the drive motor responsible for opening and closing the safety door (S) and the door (D) ( An overcurrent flows through both ends of M1) and drive motor M2, resulting in voltage intensification.

However, the voltage sensing unit 31a and the voltage sensing unit 31b detect the voltage increase generated at both ends of the driving motor M1 and the driving motor M2 and generate a detection signal.

The emergency open control unit 23a and the emergency open control unit 23a receive the detection signals generated by the voltage detection unit 31a and the voltage detection unit 31b to drive the driving motor M1 and the driving motor M2. The preamble (S) and the door (D) will be opened.

At this time, the setting time is usually set to about 5 seconds. The reason is that if the setting time is too short, even if the cage (C) is normally stopped, it may open easily when a momentary impact is applied to the safety door (S) and the door (D). This is because there is a risk that the safety door (S) and the door (D) can not be easily opened because the force should be applied for a long time even when it is abnormally stopped.

Therefore, even when the lift (L) is abnormally stopped, it is possible to easily open the door (D) of the safety door (S) and the cage (C) of each floor, thereby quickly escape from the cage (C) to occur later It is possible to ensure the safety of the occupant from unsafe safety accidents such as falling of the cage (C).

In addition, when the lift (L) normally arrives on the floor and the safety door (S) and the door (D) is opened and the occupant or material is caught between the moments when the safety door (S) and the door (D) are closed, At this time, the voltage increase occurs at both ends of the driving motor M1 and the driving motor M2, so that the safety door S and the door D can be opened.

However, at this time, since the driving motor M1 and the driving motor M2 are being driven, the emergency opening control unit 23a and the emergency opening control unit immediately after the voltage sensing unit 31a and the voltage sensing unit 31b detect the voltage increase. 23b drives the driving motor M1 and the driving motor M2 in reverse, so that the safety door S and the entrance door D are opened.

Therefore, the safety door (S) and the door (D) can be opened not only in the abnormally stopped state of the lift (L) but also in the state of occupants or materials sandwiched between them.
