Plug is fixedly connected, and spring is socketed on forcible entry arrow, one end apical grafting activity slide plate, the hook that other end apical grafting is fixed on forcible entry arrow
A, movable trigger are installed on launcher, and when forcible entry arrow is withdrawn completely, one end of movable trigger is blocked A is linked up with, back-moving spring
It is installed between launcher and movable trigger；Movable trigger is rotatablely connected by pin and launcher, and one end of movable trigger is ball
Forming head portion, the other end are provided with hook B；The movable slide plate and the contact surface at the spherical head end of movable trigger are outer inclined-plane,
The hook B and hook A contact jaws outer face are inclined-plane, and the hook A and hook B contact jaws inner face are inclined-plane.
Also include guide pad, guide pad is fixed on launcher, and forcible entry arrow is installed in guide pad, slides company with guide pad
Connect.
Compared with prior art, the beneficial effects of the utility model are：
A kind of fire-fighting detaching device, it is possible to achieve the unmanned fire-fighting detaching in high-altitude, by a hydraulic cylinder control forcible entry arrow transmitting
, simple in construction, easy to operate, low manufacture cost.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of fire-fighting detaching device of the utility model in a free state；
Fig. 2 is a kind of schematic diagram of fire-fighting detaching device of the utility model in a contracted state；
Fig. 3 is the schematic diagram under a kind of fire-fighting detaching device release conditions of the utility model.
In figure：1- transmittings hydraulic cylinder, 2- activities slide plate, 3- launchers, 4- springs, 5- activities trigger, 6- pins, 7- reset bullet
Spring, 8- forcible entry arrow, 9- hook B, 10- hook A, 11- guide pads.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings：
See Fig. 1-Fig. 3, a kind of fire-fighting detaching device, including transmitting hydraulic cylinder 1, launcher 2, spring 4, forcible entry arrow 8, activity
Slide plate 2, movable trigger 5, back-moving spring 7, transmitting hydraulic cylinder 1 are fixed on launcher 3, and movable slide plate 2 is socketed in forcible entry arrow 8
Upper, one end is fixedly connected with launching the piston of hydraulic cylinder 1, and spring 4 is socketed on forcible entry arrow 8, one end apical grafting activity slide plate 2, separately
The hook A10 that one end apical grafting is fixed on forcible entry arrow 8, movable trigger 5 are installed on launcher 3, when forcible entry arrow 8 is withdrawn completely,
One end of movable trigger 5 is blocked A10 is linked up with, and back-moving spring 7 is installed between launcher 3 and movable trigger 5；Movable trigger 5
It is rotatablely connected by pin 6 and launcher 3, one end of movable trigger 5 is spherical head, and the other end is provided with hook B9；The work
Dynamic slide plate 2 and the contact surface at the spherical head end of movable trigger 5 are outer inclined-plane, and the hook B9 is outer with hook A10 contact jaws
End face is inclined-plane, and the hook A10 and hook B9 contact jaws inner face are inclined-plane.
Also include guide pad 11, guide pad 11 is fixed on launcher 3, and forcible entry arrow 8 is installed in guide pad 11, with being oriented to
Block 11 is slidably connected.
One end of back-moving spring 7 is fixed on launcher 3, the hook B9 ends of other end connection activity trigger 5.Launch hydraulic pressure
Cylinder 1 is connected by hydraulic control system with fluid clutch.
See Fig. 1, when spring 4 is free state, the hook B9 of movable one end of trigger 5 acts in the elastic force of back-moving spring 7
Under be stuck in hook A10 on.
See Fig. 2, when transmitted, start transmitting hydraulic cylinder 1, piston is retracted, and the compression spring 4 of drive activity slide plate 2, works as activity
When slide plate 2 touches movable trigger 5, because contact surface is outer inclined-plane, the spherical head of movable trigger 5 is along inclined-plane to spring 4
Slideslip, while movable trigger 5 rotates along pin 6, the hook B9 of the movable other end of trigger 5 is moved laterally, when hook B9 takes off
During from hook A10, forcible entry arrow 8 is under the elastic force effect of spring 4 to A to launching (see Fig. 3).
When dismantling the reset of arrow 8, the transmitting piston of hydraulic cylinder 1 is stretched out, promotion activity slide plate 2 exists to B to movement, forcible entry arrow 8
The outside of movable slide plate 2 is provided with hook, and movable slide plate 2 drives forcible entry arrow 8 to B to reset, as hook A10 and hook B9 touchings
When, because hook A10 and hook B9 contact surface are inclined-plane, therefore slip can be produced therebetween, hook B9 can pressed home bullet
Spring 7 and drive activity trigger 5 rotates around pin 6, is moved laterally, and when linking up with A10 and slipping over hook B9, hook B9 can reset bullet
The elastic force effect of spring 7 is lower to be resetted, then hook A10 is blocked, and whole device returns to initial position.
The utility model is cleverly opened the control with closure by simple mechanical structure to movable trigger 5, can
To realize by emission control of a set of cylinder device completion to forcible entry arrow 8, easy to operate, low manufacture cost.
