Problems solved by technology
Therefore, when the device used to raise or lower the elevator door has an indication failure, or the elevator itself has an operational failure during the upward or downward process, and the staff on the floor do not know the situation at this time, they still open the protective door for operation. Then there may be a safety accident of accidental falling, so it needs to be improved.

Embodiment 2
[0108] The existing conventional electric push rod 3 usually has two kinds of self-locking function or without self-locking function. If the conventional push rod is used, there will be the following problems. If the electric push rod 3 with self-locking function is used, it will Under abnormal conditions, the protective door will be self-locked and cannot be opened or closed. If the electric push rod 3 without self-locking function is used, the protective door will be easily opened or closed artificially during use, so there is a potential safety hazard; and the existing The overload protection method of the electric push rod 3 is usually current sensing protection, that is, when the motor current of the electric push rod 3 is too large, the power-off protection is carried out. Although it can achieve the function of power-off protection, it will It is inconvenient to use when the power is turned off, and when the current of the motor itself is too large, it is easy to cause d...

The invention discloses an intelligent elevator and floor protective door opening and closing linkage device and a control method thereof. Automatic linkage control of an elevator and a protective door can be realized, the structure is simple, the safety is good, and the device is characterized by comprising the elevator which comprises an elevator door and a driving unit for driving the elevator door to be opened and closed, the protective door, an electric push rod and a control unit. The protective door is mounted on the corresponding floor and comprises a door frame and a door plate rotationally hinged to the door frame; the electric push rod is mounted between the door frame and the door plate and used for driving the protective door to be opened or closed; and the control unit is used for controlling the operation states of the elevator and the protective door. The device is suitable for the technical field of building construction.
Description
technical field [0001] The invention belongs to the technical field of building construction, in particular to an intelligent elevator floor protective door switch linkage device. Background technique [0002] At present, during the transportation of building construction elevators, the materials are generally transported to the floor to be stopped by the elevator. The elevator is located in the floor derrick, and the floor derrick is provided with a floor protection door. The floor protective door on the derrick needs to be opened, and the door of the elevator also needs to be opened; but the existing protective door and the elevator usually belong to different control systems, and the protective door is generally opened by manual control of the construction personnel in the floor; The lifting device on the elevator is driven to lift and open, which belongs to the elevator control system. Therefore, when the device used to raise or lower the elevator door has an indication...
