The specific embodiment
Preferred implementation of the present invention is described with reference to the accompanying drawings.
Fig. 1 is the constructional drawing of the lift appliance of expression embodiments of the present invention 1.Among the figure, car 1 and counterweight 2 hang in the hoistway by main rope 3, the lifting in hoistway by the propulsive effort of winch 4.
Winch 4 has: the drive pulley 5 of the main rope 3 of having reeled, make drive pulley 5 rotation electrical motor 6, follow advancing of car 1 and with the rotation of drive pulley 5 one as the brake wheel 7 of drg swivel and the drg portion main body 9 that the rotation of drive pulley 5 is braked.By come the driving at control motor 6 as the drive control part 10 of operation control section.
Drg portion main body 9 has: can with the brake shoe 15 of brake wheel 7 contact separations, be installed in armature 16 on the 1st brake shoe 15, brake shoe 15 by be pressed in the retarding spring 17 on the brake wheel 7 and be configured to armature 16 in opposite directions, produce and overcome retarding spring 17 and make brake shoe 15 leave the brake coil 18 of the electromagnetic force of brake wheel 7.
Between brake coil 18 and power supply 19, be connected in series with brake switch 22 and timer switch 28.Cut off the electric power that brake coil 18 is provided by the either party at least in the cut- off switch 22,28, by retarding spring 17 brake shoe 15 by being pressed on the brake wheel 7.Timer switch 28 is closed usually.Therefore, provide electric power by brake switch 22 closures to brake coil 22 usually, make brake shoe 15 leave brake wheel 7.
Come the on/off of control brake device switch 22 by drg control part 23.Drg control part 23 is made of the microcomputer that possesses arithmetic processing section (CPU), storage part (ROM and RAM etc.) and signal input and output portion.
In addition, when in car 1 is advanced, having produced the drg work order, being emergency braking when instruction, drg control part 23 is estimated the deceleration/decel of car 1 according to the deceleration/decel estimated information that is used to estimate the deceleration/decel (absolute value of negative acceleration/accel) of car 1, control results from the electromagnetic force (open and-shut mode of brake switch 22) in the brake coil 18, so that deceleration/decel can be not excessive or too small.Thus, drg control part 23 control brake boots 15 are for the pressing force of brake wheel 7.
As the deceleration/decel estimated information, can use the rotation that detects electrical motor 6 the winch rotation detector, be arranged on car position detector on the governor, detect the rotation of the backhaul wheel that is wound with main rope 3 backhaul wheel rotation detector, detect the load in the car 1 scale device, be installed in speed gauge or the accelerometer on the car 1 or detect the axial torque meter etc. of the axial torque of drive pulley 5.Can use coder or resolver as rotation detector and car position detector.
For example can use open and close type switch that can break-and-make switch (chopping) or the sliding-type switch that continuously changes resistance value etc. can regulate switch as brake switch 22 to the energising amount of brake coil 18.Below in the present embodiment, the situation of using the open and close type switch is described, and under the situation of using the sliding-type switch, will replaces on/off switch, and slide switch is to change resistance value.
And, when having removed the drg work order, restart the timer circuit instrumentation of 29 pairs of times, timer switch 28 closures.The brake gear of embodiment 1 has drg portion main body 9, brake switch 22, drg control part 23, timer switch 28 and timer circuit 29.
In this lift appliance, since from produced the emergency braking instruction time passed through the control that makes 23 pairs of braking forces of drg control part behind the specified time become invalid, so the deceleration/decel in the time of both can suppressing emergency braking can also make car 1 stop when drg control part 23 produces fault again reliably.
Below, Fig. 2 is the constructional drawing of the lift appliance of expression embodiments of the present invention 2.Among the figure, between brake coil 18 and power supply 19, be connected with current limiter 27 and change-over switch 27a.The electric current of brake coil 18 is flow through in current limiter 27 restrictions.Can use for example resistor as current limiter 27.Change-over switch 27a carries out following switching, promptly provides it to brake coil 18 by current limiter 27 restriction from the electric current of power supply 19, or not-go end stream device 27 provides it to brake coil 18.
Particularly, change-over switch 27a switches to the circuit side of not-go end stream device 27 usually.Relative therewith, when producing the drg work order, change-over switch 27a switches to the circuit side by current limiter 27.And when having removed the drg work order, change-over switch 27a turns back to the circuit side of not-go end stream device 27.Other structures are identical with embodiment 1 with action.
In this lift appliance, by using current limiter 27, setting can only apply the part of power line voltage by the upper limit to the energising amount of brake coil 18 of drg control part 23 controls to brake coil 18.Therefore, the controlling quantity of 23 pairs of drg portions of limit stop control part main body 9 suitably.
