A certain degree of to move down, even if it is safe distance that this, which moves down distance, now limiter of speed easily produces erroneous judgement, cuts off traction electromechanical source
And the operation of safety tongs locking elevator is triggered, influence the normal operation of elevator；
2nd, because existing elevator is when door is opened, the ejection of limiter of speed electromagnet comes, when elevator goes further dynamic 30mm, speed limit
Device does not walk idle stroke, causes limiter of speed to act, descending lifting safety tongs action, up lifting rope brake action, so can not
Carry out advance door opening action, thus enabling of the existing elevator in flat bed and shutdown action be after elevator stops completely
Switch door operation is carried out, in the operation of high-rise express lift (the general speed of service is 2.0m/s or more than 2.5m/s), this
The operational efficiency of elevator can be greatly reduced in the switch gate control operation of class.Existing high-rise express lift is also that part elevator possesses and carried
Button fly front function, but this function is intended to change the execution logic of operation program and release mechanism, setting up procedure is complicated, cost compared with
It is high.

The present invention the new cooperation for having computer room limiter of speed by banking pin, U-lag and leverage, make banking pin by
Take place during offset motion drives rope brake or safety tongs to triggering leverage and form a vacant formation, in the row
The motion of journey inside brake pin does not produce triggering effect, it is achieved thereby that occurring the problem of prevent false triggering maloperation；Work as door simultaneously
During opening, the ejection of limiter of speed electromagnet, opening door operation is now can perform, when elevator goes further dynamic 30mm, limiter of speed walks sky
Stroke, banking pin walk idle stroke in arc groove, and limiter of speed still will not act, and would not also set out safety tongs and rope brake moves
