And a brake release coil 18 that is disposed to face the armature 16 and generates an electromagnetic force that separates the brake shoe 15 from the brake drum 7 against the brake spring 17.
- a brake switch 22 is connected as a power cut-off unit.
- an adjustment switch 22 a as a current adjustment unit is connected in parallel with the brake switch 22 between the brake release coil 18 and the power source 19.
- the brake switch 22 is directly opened and closed according to the presence or absence of a brake operation command (including a normal braking command and an emergency braking command). That is, when a brake operation command is generated, the brake switch 22 is opened. When the brake operation command is released, that is, when the brake release command is generated, the brake switch 22 is closed. Brake operation command and blur The brake release command is generated by an elevator control unit including the drive control unit 10. As the brake switch 22, a normal opening / closing switch is used.
- the adjustment switch 22a is normally opened. That is, the adjustment switch 22a is opened except when the deceleration of the force 1 (the absolute value of the negative acceleration) exceeds a predetermined value.
- a switch capable of adjusting the energization amount to the brake release coil 18, such as a switchable switch that can be switched or a slide switch that continuously changes the resistance value is used as the adjustment switch 22a.
- a switch capable of adjusting the energization amount to the brake release coil 18 such as a switchable switch that can be switched or a slide switch that continuously changes the resistance value.
- a slide switch is used, the resistance value is changed by sliding the switch instead of turning on the switch.
- the brake control unit 23 is composed of a microcomputer having an arithmetic processing unit (CPU), a storage unit (ROM, RAM, etc.) and a signal input / output unit.
- the brake control unit 23 monitors the deceleration of the car 1 while it travels regardless of whether or not there is a brake operation command, and sets the brake release coil 18 so that the deceleration does not become excessive or excessive.
- the generated electromagnetic force that is, the open / close state of the adjustment switch 22a is controlled.
- the brake control unit 23 detects and monitors the deceleration of the car 1 independently of the drive control unit 10. That is, the deceleration estimation information for measuring or estimating the deceleration is directly input to the brake control unit 23 from a sensor or the like that is not from the elevator control unit.
- the hoisting machine rotation detector that detects the rotation of the motor 6, the car position detector provided in the governor, and the rotation of the return wheel on which the main rope 3 is wound are detected.
- a return wheel rotation detector, a scale device that detects the load in the car 1, a speedometer or accelerometer mounted in the car 1, or an axial torque meter that detects the axial torque of the drive sheave 5 may be used. it can.
- An encoder or resolver may be used as the rotation detector and car position detector. You can.
- the brake control unit 23 When the deceleration of the force 1 exceeds a predetermined value, the brake control unit 23 generates a deceleration reduction command.
- the adjustment switch 22a supplies electric power to the brake opening coil 18 while adjusting the amount of current according to the deceleration reduction command, and reduces the deceleration of the force. At this time, since the adjustment switch 22a is connected in parallel to the brake switch 22, even if the power supply to the brake release coil 18 is cut off by the brake switch 22, the brake is released. Electric power can be supplied to the coil 18.
- the brake device includes a brake unit body 9, a brake switch 22, an adjustment switch 22a, and a brake control unit 23.
- an adjustment switch 22a for adjusting the braking force is arranged in a circuit parallel to the brake switch 22, and the brake switch 22 is immediately opened in response to a brake operation command.
