Description
Technical field
The present invention relates to the emergency stop switch shift assembly in the elevator field, especially a kind of elevator sudden-stop switch device moving up and down.
Background technology
Along with the continual and steady fast speed development of China's economy, skyscraper increases sharply, and elevator is widely used, and to people, brings comfortable, enjoyment efficiently.In China, the elevator service that surpasses 1,000,000 is arranged at present in multiple places such as office room, apartment, markets.According to the data of Chinese elevator association, show, in recent years, the elevator quantity that China puts on record on the regular payroll just with every year higher than 20% speed increment, become the country of global elevator recoverable amount maximum.
Elevator belongs to special equipment, the fine or not direct relation of its quality user's safety, so the safety requirements of elevator is very high, perfect maintenance could realize the elevator reliability service, in elevator after-sales service maintenance business frequently, elevator maintain and protection personnel's personal safety is also very important.
In the daily repair and maintenance or checkout procedure of elevator; the elevator maintain and protection personnel must enter pit and carry out operation; elevator pit entrance emergency stop switch (suddenly stopping) nearby be serially connected in a kind of in the elevator control path can not automatically reset hand switch; when in case of emergency; for preventing that elevator from starting operation, emergency stop switch need to be closed to the cutting-off controlling circuit to guarantee safety.
When entering pit, first urgency is stopped pressing (cutting-off controlling circuit), enter after pit overhauled, repair and maintenance; or urgency is stopped to recover to carry out again every check, anxious quantity of stopping is not required, as long as it is just passable to meet operating needs; so fill one, also have to fill that two urgency stop.
In the situation that fill a urgency, stop: generally be arranged on the nearby slightly higher place than landing sill of pit entrance, the repair and maintenance personnel are opening layer behind the door, perhaps half couchant body is pressed anxious stopping with hand, or directly presses with pin, does so certain difficulty, both inconvenient, also increased dangerous (as fallen lower pit), and from cat ladder goes down, if cat ladder is not near anxious stopping, stand in pit and want that the urgency of recovering eminence stops also having in the darker situation of certain difficulty, particularly pit.
In the situation that fill two urgency, stop: general upper urgency stop being contained in apart from landing sill approximately 1.5 meters high near, the next urgency stops being contained in apart from the end, hole approximately on 0.5 meter high well enclosure, generally, two urgency stop nearby having cat ladder.When entering pit; first upper urgency is stopped pressing; then climbing down pit stops the next urgency to press; then climbing up cat ladder stops upper urgency to recover; climb down again that pit is overhauled, repair and maintenance; or more the next urgency is stopped to recover, carry out every check, after the inspection man completes, then climb out of before pit and also will first press the next urgency and stop, press upper urgency and stop, recover the next urgency and stop, climb out of after pit and recover again upper urgency and stop by cat ladder.Climb up like this and climb down for several times, increased work capacity, reduced work efficiency, inconvenience is arranged in practical operation.
Above-mentioned two situations, exist in practice some repair and maintenance personnel when fatigue or in order to follow the line of least resistance, contrary to regulations requires to be failure to actuate and suddenly stops, and directly climbs up the situation that climbs down pit repair and maintenance, check, this has increased the probability of occurrence of safety misadventure virtually, has buried potential safety hazard.
Summary of the invention
