Problems solved by technology

[0018]However, the voltage that drives the airflow generating device that uses plasma discharge is high voltage, and people may get an electric shock if they come into contact with the airflow generating device
In the state where the rectifying plate or baffle plate vertically installed at the front end of the car door sill appears at the elevator opening, it is not desirable that the air flow generating device applied with high voltage is exposed to the maintenance personnel.

Embodiment Construction

[0070] Below, refer to Figure 1 to Figure 11 , an elevator safety device according to an embodiment of the present invention will be described. In each figure, the same code|symbol is attached|subjected to the same part, and overlapping description is abbreviate|omitted.

[0071] (first embodiment)

[0072] figure 1 It is a block diagram of an elevator equipped with an elevator safety device according to a first embodiment of the present invention. The elevator 10 has a hoistway 11 of a building, and in the hoistway 11 , one end of a cable 13 suspended from a hoist 12 is connected to a passenger car 14 and the other end is connected to a counterweight 15 . The passenger car 14 is provided with a car door 18 corresponding to the hall door 17 for opening and closing the entrance 37 of the lobby 16 of each floor. In the lower part of the passenger car 14, an operator's console 19 for entry of an operator is formed. This console 19 is comprised from the box-shaped frame 21 p...

Abstract

The present invention provides an elevator safety device capable of reducing aerodynamical noise generated in high speed running of an elevator, and maintainers can operate safely for maintenance, examination and the like. The elevator safety device has a passenger compartment (14), current plates (28a) (28b) positioned on the passenger compartment (14) for commutating the air current surroundingthe passenger compartment (14), a plasma generator (1) positioned on the current plates (28a) (28b) and generating flaky air currents under the action of discharging plasma, a door (17) for opening and closing a gateway (37), a door-closing acknowledging switch (38) which is positioned on the door (17), is opened when the door (17) is opened and is closed when the door (17) is closes, and a control device (23) for controlling the opening or closing driven by the plasma generator (1), controlling the power on or power off of a power supply for supplying power to the plasma generator (1) according to the state of the door-closing acknowledging switch (38), and cutting off the power supply of the plasma generator (1) when the door-closing acknowledging switch (38) is in an off state.

Description

technical field [0001] The invention relates to an elevator safety device. Background technique [0002] When the maintenance personnel maintain and inspect the elevator, they need to ensure the safety of the operation. Generally speaking, the maintenance personnel will open the hall door and perform inspection operations in the hall. Maintenance personnel remove the baffle under the car in the lobby to perform various maintenance. The operation mode of the elevator is set to the inspection operation mode, and the maintenance operation is performed with the car stopped at a height position required by the maintenance personnel. In this state, maintenance personnel perform inspections, repairs, adjustments, and the like of various mechanical devices, control devices, and the like. [0003] Along with the increase in the height of the building, the elevators installed in the building are also increasing in speed. In high-speed elevators, aerodynamic noise caused by airflow...
