Toward detection switch, slide bar one end is inserted in sliding sleeve from the other end of sliding sleeve, and is also inserted in simultaneously
In overcoat, by the slip in overcoat and sliding sleeve of the slide bar one end, it is possible to make the other end of slide bar
And the hypotelorism between detection switch, draws one end of pin to be located in the installing hole of deceleration pusher side shaft coupling,
And be fixed on deceleration pusher side shaft coupling by nut, the other end is fed through the installation of motor-side shaft coupling
Hole and overcoat, be connected with one end of slide bar in overcoat, the end face of slide bar one end and the inner side of overcoat one end
Being additionally provided with spring between face, spring housing is sheathed on the other end drawing pin.
Described sliding sleeve internal diameter is less than outer casing internal diameter so that it is the inside of connecting place can form a step.
It is additionally provided with keyway on described slide bar, the medial surface of sliding sleeve is additionally provided with match with keyway flat
Key.
Described detection switch is fixed on the position corresponding with slide bar by support.
Described drawing is additionally provided with door outside pin.
Also include acoustic-optic alarm, electrically connect with detection switch, be located at main behaviour indoor.
This utility model can real-time tracking detection safety pin duty, when one or two safety
Pin overload was cut off when losing efficacy, and safety device sends signal, the transmission of mair motor is tightly stopped, it is to avoid by machine
Frame is hauled out by force from mill housing and is caused transmission universal drive shaft, frame lifting device, mill housing to damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the field erected schematic diagram of this utility model.
Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings with embodiment.
As it is shown in figure 1, the protection device of a kind of safety coupling that this utility model provides, including outside
Set 1, sliding sleeve 2, slide bar 3, draw pin 4, detection switch 5 and be opened in motor-side shaft coupling 6 respectively
With the installing hole 8,9 on deceleration pusher side shaft coupling 7, motor-side shaft coupling 6 is located in one end of overcoat 1
Installing hole 8 in, the other end is connected with one end of sliding sleeve 2, and the other end of sliding sleeve 2 is toward detection
Switch 5, slide bar 3 one end is inserted in sliding sleeve 2 from the other end of sliding sleeve 2, and be also inserted in simultaneously in
In overcoat 1, by the slip in overcoat 1 and sliding sleeve 2 of slide bar 3 one end, it is possible to make slide bar 3
The other end and detection switch 5 between hypotelorism, draw one end of pin 4 to be located at deceleration pusher side shaft coupling
In the installing hole 9 of device 7, and being fixed on deceleration pusher side shaft coupling 7 by nut, the other end wears
Cross installing hole 8 and the overcoat 1 of motor-side shaft coupling 6, be connected with one end of slide bar 3 in overcoat 1,
It is additionally provided with spring 10, spring housing 10 between end face and the medial surface of overcoat 1 one end of slide bar 3 one end
It is sheathed on the other end drawing pin 4.
It is also preferred that the left described sliding sleeve 2 internal diameter is less than overcoat 1 internal diameter so that it is the inside of connecting place can
Form a step, so, when slide bar 3 is when sliding, the effect of backstop can be played.
It is also preferred that the left be additionally provided with keyway 11 on described slide bar 3, the medial surface of sliding sleeve 2 is additionally provided with set
Enter keyway 11 flat key 12 matched with keyway 11, it is therefore prevented that slide bar 3 is at overcoat 1 and sliding sleeve
Rotate in 2.
It is also preferred that the left described detection switch 5 is fixed on the position corresponding with slide bar 3 by support 13
Put, after position and the slide bar 3 of detection switch 5 is adjusted, could effectively sense with slide bar 3 it
Between distance.
It is also preferred that the left described drawing is additionally provided with door 14 outside pin 4, door 14 is bolted on
On deceleration pusher side shaft coupling 7, when drawing pin 4 to be pulled off, door 14 is possible to prevent post-rift drawing
Pin 4 is bound to outside.
Furthermore it is also possible to connect an acoustic-optic alarm, acoustic-optic alarm is arranged on main behaviour indoor,
Corresponding frame safety pin fault can be pointed out according to display lamp on device, easily facilitate inspection and process.
As in figure 2 it is shown, this utility model is when working site is installed and used, when former coupler safety pin
When being cut off, the pin 4 that draws in this utility model is also cut off, with the slide bar 3 drawing pin 4 to be connected simultaneously
Move to detection switch 5 directions rapidly under spring 10 acts on, blocked by sliding sleeve 2 time to step,
Owing to the movement of slide bar 3 makes the distance between itself and detection switch 5 diminish, thus open detection and open
Closing 5, detection switch 5 transmits signals to control system, and whole piece roll line is promptly stopped by control system
Only, it is to avoid after a Main Drive of Rolling Mill disconnects, remaining five roughing mill is still rotating, and causes equipment to be subject to
To the consequence damaged.Use threaded, in order to prevent shaft coupling owing to drawing pin 4 and slide bar 3 to be
Draw when high speed rotating pin 4 to rotate from slide bar 3 to escape from, therefore keyway has been offered in design on slide bar 3
11, the medial surface of sliding sleeve 2 is additionally provided with and is inserted in keyway 11 flat key that matches with keyway 11
12, with limit slide bar 3 with draw pin 4 relative motion.
