Specifically, the installation manner of the movable member 40 movably installed on the base 20 along the vertical direction is not limited, and may be that an installation groove is formed in the base 20 along the vertical direction, the movable member 40 is installed in the installation groove, for convenience of installation, the movable member 40 includes a swing rod 43, the swing rod 43 has an installation end and a movable end which are opposite to each other, and the installation end of the swing rod is rotatably installed on the base 20 along the vertical direction; the contact part 42 is arranged at the movable end of the swing rod; the driving part 41 is disposed at the middle section of the swing link 43. With such an arrangement, when the head assembly 10 moves upwards, the driving portion 41 can be driven to move upwards, so as to drive the swing rod 43 to rotate upwards, and the contact portion 42 is disposed at the movable end of the swing rod 43, so that the contact portion 42 also moves upwards, thereby pressing the switch member 30, and completing the power supply cut-off of the elevator. By providing the swing link 43, the movable member 40 can be mounted on the base 20 only by rotatably mounting the swing link 43 on the base 20, so that the driving portion 41 and the contact portion 42 do not need to be separately mounted, and the mounting process is simplified. The installation end can be provided with an installation hole, the seat body is provided with a convex rib, the installation hole is sleeved on the convex rib, and the convex rib is sleeved with a nut for fixing.

The elevator device generally has more than one steel wire rope, in order to detect a plurality of steel wire ropes simultaneously, the driving part 41 is arranged at intervals along the length direction of the swing rod 43 and is used for corresponding to a plurality of rope heads arranged in rows on the base 11, the arrangement is that after the rope heads of the plurality of steel wire ropes are arranged on the base 11, the top of each rope head is abutted with one driving part 41, at the moment, as long as one steel wire rope is subjected to tension change or fracture and moves upwards, the driving part 41 is driven to move upwards, so that the power supply of the elevator is cut off, and the operation of the device is stopped.

The form of the driving part 41 is not limited, and may be a bolt 411, the height of the steel wire rope above the base 11 is different under different pressures, and the swing rod is provided with a threaded hole along the upper and lower direction 43; the driving part 41 comprises a bolt 411, the bolt 411 extends out of the threaded hole downwards and is in threaded connection with the threaded hole, the depth of the bolt is adjusted through adjusting the threads between the bolt and the threaded hole, the downward extending length of the bolt is adjusted, the bolt 411 can be adjusted relative to the downward distance of the threaded hole, when the tensile force applied to the steel wire rope changes, the height of the steel wire rope changes, and the steel wire rope can adapt to rope heads with different heights by adjusting the bolt 411.

When the tensile force that wire rope received is fixed, the height does not change, for the convenience of installation, drive division 41 includes the screw rod, the pendulum rod is equipped with the screw rod mounting hole, the screw rod welds in the screw rod mounting hole, so sets up, the downward distance of screw rod is set up before the welding, need not adjust after the installation the pendulum rod the distance that drive division 41 supports downwards again.

Further, in order to guide the upward movement of the movable member 40, the driving portion 41 includes a socket fixedly installed at the swing lever and extended downward to abut against the top of the head assembly 10. The top of the head assembly 10 is sleeved by the pipe sleeve, and when the head assembly 10 moves upwards, the pipe sleeve can effectively transmit an upward force to the movable member 40, so that the driving portion 41 is prevented from being misaligned with the head assembly 10 due to time, and thus the rising of the top of the head assembly 10 cannot be effectively detected.

Because the height of the head assembly 10 relative to the base 11 varies under different pressure conditions, in order to ensure that the movable member 40 is located above the head assembly 10, the switch member 30 is located above the movable member 40, and the height of the switch member 30 and/or the movable member 40 needs to be adjusted within a certain range, the elevator rope slack detection apparatus 100 further includes a lifting member 50, wherein the lifting member 50 is configured to be mounted to the base 11 and connected to the movable member 40 and/or the switch member 30 for correspondingly adjusting the height of the movable member 40 and/or the switch member 30; wherein the lifting assembly 50 constitutes the base 20. Through the adjustment of the lifting assembly 50, the height of the switch element 30 and/or the movable element 40 can be adjusted, so that the movable element 40 is positioned above the cord end assembly 10, and the switch element 30 is positioned above the movable element 40. Specifically, the lifting assembly 50 may be two sections of seat bodies which can be extended and retracted, and the height can be adjusted by extending and retracting, or the lifting assembly 50 may include a long rod bolt 51 and two nuts 52, the long rod bolt 51 is screwed to the seat body 20 and the base 11, the two nuts 52 are sleeved on the long rod bolt 51 and are located between the seat body 20 and the base 11, so as to adjust the height of the seat body 20 when adjusting the distance between the two nuts 52, so that the height can be adjusted by adjusting the distance between the nuts 52, the operation is simple, and on the other hand, the long rod bolt 51 and the two nuts 52 are parts which are often used in industrial production and are easy to obtain.

In order to increase the moment of the contact portion 42 to the switch member 30, the contact portion 42 is inclined downward relative to the middle section of the swing rod, so that when the contact portion 42 moves upward, one end of the switch member 30 can be pressed all the time to maximize the moment, and on the other hand, when the contact portion 30 contacts one end of the contact portion 42, the contact portion 42 is separated from the contact portion 42 only after the full length of the stroke of the contact portion 42 is completed, so that the pressing time is increased.

In order to prevent an accident by generally reducing the tension of the wire rope when the head assembly moves upward, the elevator wire rope slackening detecting apparatus 100 further includes: a standby steel wire rope and a standby motor 60, wherein one end of the standby steel wire rope is used for connecting the lifter; the standby motor 60 is arranged at the upper end of the switch member, the standby motor 60 is in driving connection with the other end of the standby steel wire rope and is electrically connected with the switch member 30, so that the standby steel wire rope is tightened when the switch member 30 cuts off the power supply of the elevator. With this arrangement, when the elevator normally operates, the standby motor 60 does not apply work to the elevator, and after the switching element 30 cuts off the power supply of the elevator, in order to prevent an accident, the standby motor 60 stretches the elevator to increase the pulling force on the elevator, thereby preventing the elevator from falling.
