no. 1 Embodiment approach

[0053] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0054] Figure 1 to Figure 4 It is a figure which shows the 1st Embodiment of the hoisting rope braking device of the elevator according to this invention.

[0055] First, through figure 1 as well as figure 2 An elevator system incorporating the rope braking device of the present invention will be described. like figure 1 As shown, the elevator system includes a car 4 and a balance counterweight 5 connected to the car 4 via a main traction rope 3 , the main traction rope 3 is driven by the drive wheel 1 and is hung on the deflector wheel 2 . In addition, the main hoisting rope 3 is restrained by a hoisting rope brake device 6 having a hoisting rope restraining member (hoisting rope brake) 7 held in an open state by a trigger 8 .

[0056] like figure 2 As shown, trigger 8 is sucked and held by trigger solenoid 9 , and voltage 17 is applied to trigger solenoid 9 f...

no. 2 Embodiment approach

[0078] Next, pass Figure 5 A second embodiment of the hoisting rope brake of an elevator according to the present invention will be described.

[0079] Figure 5 The second embodiment shown differs only in the configuration of the control unit 10, and is otherwise the same as Figure 1 to Figure 4 The first embodiment shown is substantially the same.

[0080] exist Figure 5 in, for with Figure 1 to Figure 4 The same parts as in the first embodiment shown are given the same symbols, and detailed descriptions are omitted.

[0081] like Figure 5 As shown, in the control unit 10, it is first judged whether or not an operation command has been output to the power supply 25 for the trigger operation limiting mechanism.

[0082] When an operation command is output to the trigger operation limiting mechanism power supply 25 and an operation confirmation signal 23 is input from the trigger operation limiting mechanism switch 22, it is determined that the hoisting rope brake d...

no. 3 Embodiment approach

[0089] Next, pass Image 6 A third embodiment of the hoisting rope brake of an elevator according to the present invention will be described.

[0090] Image 6 The third embodiment shown differs only in the structure of the control unit 10, and is otherwise the same as Figure 1 to Figure 4 The first embodiment shown is substantially the same.

[0091] exist Image 6 in, for with Figure 1 to Figure 4 The same parts as in the first embodiment shown are given the same symbols, and detailed descriptions are omitted.

[0092] like Image 6 As shown, the control unit 10 outputs an operation command to the power source 25 for the trigger action limiting mechanism when the trigger action limiting mechanism 26 moves to the limiting side during a power failure and the main hoisting rope 3 is restrained by the hoisting rope brake 7 . The control unit 10 determines whether the trigger operation restricting mechanism 26 has been reset to a position where the operation of the trigge...

Abstract

Provided is a brake device for an elevator horseline, capable of monitoring whether a motion of a trigger motion limiting mechanism for limiting the motion of a trigger is correct or not always. The brake device (6) includes a horseline brake (7) for binding a main horseline (3), a trigger (8) for holding the horseline brake (7) with an opening state, and a trigger motion limiting mechanism (26) for limiting the motion of the trigger (8). The motion of the trigger motion limiting mechanism (26) is determined by a trigger motion limiting mechanism switch (22). A control part (10) controls the drive of the trigger motion limiting mechanism (26) based on signals of the trigger motion limiting mechanism switch (22).

Description

technical field [0001] The present invention relates to a hoisting rope braking device of an elevator, in particular to an elevator hoisting rope braking device including a trigger action limiting mechanism that limits the action of a trigger. Background technique [0002] Conventionally, as a hoisting rope braking device of an elevator, following braking devices are known, which include: a hoisting rope brake that clamps a main hoisting rope of an elevator car to constrain the main hoisting rope, and a hoisting rope brake that restrains the main hoisting rope. The trigger for the rope brake to remain open. [0003] In such an elevator rope brake device, when the rope brake is held in an open state, a voltage is applied from a power source to a solenoid, and the solenoid attracts and holds the trigger to hold the rope brake in an open state. open state. That is, when the disconnection condition of the hoisting rope brake device is detected, the voltage application to the s...
