Embodiment
As shown in Figures 1 to 4, the rapid unhooking mechanism of the present invention with auxiliary catch, mainly by coupler body component, unhook
Transmission component, insurance gib head and unhook control assembly composition.
Described coupler body component is mainly made up of 11, two blocks of coupler body side plates 12 of hook fixed seat and hook bearing pin 13.Wherein,
Hook fixed seat 11 is integrally fixed in the frame in plant equipment (in the frame of such as rope brake).Two blocks of coupler body side plates 12 phase side by side
Between arrange, the same side of the two coupler bodies side plate is arranged on the hook fixed seat in a rotatable manner by linking up with bearing pin 13
In, it is equipped with hook portion 121 on the two coupler bodies side plate.
The unhook transmission component is mainly made up of 21, two activity swing arms 22 of suspended axle and swing arm power transmission shaft 23.Wherein,
The axis body of suspended axle 21 is partially disposed in the hook portion 121 of two coupler body side plates.One end of two activity swing arms respectively with suspended axle 21
Both ends connection；The other end of two activity swing arms is connected with swing arm power transmission shaft 23 respectively.Swing arm power transmission shaft exports power drive
Other mechanism actions (such as rope brake).
Described insurance gib head 3 corresponds to hook portion 121 by a gib head bearing pin 31 and is arranged on two coupler bodies in a rotatable manner
Between side plate, it which is provided with and contradict breach 32 and boosting arm 33.
Described unhook control assembly is mainly by unhook control panel 41, steel-wire flexible-shaft 42, dynamic clamping head and quiet clamping head and spacing company
Dynamic component composition.Wherein, the side of unhook control panel 41 is arranged on two coupler body sides in a rotatable manner by linking up with bearing pin 13
Between plate 12 and co-axial it can rotate；The opposite side of unhook control panel 41 is provided with conflict projection 411 triangular in shape, the conflict
Projection 411 coordinates with contradicting breach 32 and contradicting；Unhook control panel 41 and the side at hanger pin axis connection position extend outward one
Individual lever arm 412.Steel-wire flexible-shaft 42 is connected with unhook control panel 41, is rotated for drawing unhook control panel around hook bearing pin.
In the present embodiment, described dynamic clamping head and quiet clamping head is a torsionspring 43, and the spring body part of the torsionspring is set in hanger pin
On axle 13, one torque arm is fixed in the frame in plant equipment (in the frame of such as rope brake), and its another torque arm is then solid
It is scheduled on the side of lever arm 412.Spacing linked component is provided between unhook control panel 41 and two coupler body side plates 12, this reality
The spacing linked component for applying example is made up of spacing hole 441 and spacing bearing pin 442：Spacing hole 441 is that circular port (can also be kidney-shaped
Hole), it is opened on the plate body of unhook control panel 41；The axis body of spacing bearing pin 442 partially passes through spacing hole 441 and its both ends difference
It is fixed on two hook side plates 12, moreover, the cross-sectional area of spacing bearing pin is less than the area of spacing hole so that spacer pin
Certain relative displacement can occur in spacing hole for axle.
The operation principle of the present invention is as follows：
As shown in figure 1, when the present invention is in normal operating conditions, suspended axle is hung on coupler body component, unhook control panel
Contradicted in the presence of torsionspring elastic force and insure gib head, insurance gib head is limited suspended axle improper in hook portion
Depart from (malfunction).When needing to break off relations, unhook control panel is pulled to rotate (now gib head side plate is motionless) by steel-wire flexible-shaft,
Unhook control panel no longer contradicts insurance gib head, and then limitation of the arming gib head to suspended axle.When steel-wire flexible-shaft continues to draw
When dynamic, the spacing hole on unhook control panel is in contact with spacing bearing pin and rotated together with driving two coupler body side plates simultaneously, when
Rotational angle becomes larger, and the line between hook bearing pin and gib head bearing pin center, auxiliary catch are gradually left in the center of suspended axle
Head has gone to unbalanced position simultaneously, and in the presence of spring force (load), suspended axle accelerates to promote insurance gib head to rotate
Until it is away from one another, so as to realize that rapid unhooking discharges, and then drive other machinery mechanism action (such as rope brake).
Present invention is suitably applied to need break off relations control plant equipment, the rope brake for the elevator that is particularly suitable for use in, such as
201210311661.7 disclosed progressive rope gripper and the gradual overspeed protection safety device of traction-type jacking equipment, and
201520597337.5 disclosed gradual bidirectional rope gripper.
