The operation principle of the damping brake device is：
During original state：Arresting disc 17 and dampened disk 16 do not contact, and arresting disc 17, left installing plate 19 and connecting shaft 7 exist
Coaxial rotation under the drive of equipment rotation axis to be braked；Clamping cylinder 10 is contacted with separate sheet 1 at this time, dampened disk 16 does not contact.
Braking procedure：Need to treat braking equipment when being braked, swing brake bar 2, brake bar 2 drives clamping cylinder 10 to revolve
It is moved to the left while turning, clamping cylinder 10 is separated with separate sheet 1, is contacted with dampened disk 16；And then promote dampened disk 16, spring
Block plate 15 overcomes the elastic force of resetting spring 13 to be moved vertically to 17 place direction of arresting disc, i.e., brake bar 2 drives clamping cylinder 10
Progressively compression dampened disk 16 is moved axially to the left, until dampened disk 16 is contacted by friction plate with arresting disc 17, dampened disk 16
Band movable friction plate 20 compresses arresting disc 17 and is braked.Since dampened disk 16 and arresting disc 17 are pyramidal structure, dampened disk 16 moves
Dampened disk 16 and arresting disc 17 are smoothed out to center, braking damping during dynamic, and insensitivity is good.
When needing to reset, opposite direction swings brake bar 2, while 10 opposite direction of drive clamping cylinder of brake bar 2 rotates to the right
It is mobile, clamping cylinder 10 is separated with dampened disk 16, contacted with separate sheet 1；And then drive dampened disk 16 to move to right by separate sheet 1,
The auxiliary pushing dampened disk 16 under the action of 13 restoring force of resetting spring of reseting disk 12 moves to right at the same time, ensures return disk 12, damping
Disk 16, clamping cylinder 10 keep contact gapless, make the steady noiseless of device.
Since dampened disk 16 and arresting disc 17 brake damping action as the circumference braking damping of face contact everywhere, apply everywhere
Braking damping thrust is identical, and frictional force is identical, has latching characteristics, revolving part positive and reverse return between connecting cylinder 5 and clamping cylinder 10
Braking damping action can be played when turning and braking damping action effect is identical.
To prevent maloperation, limiting device is provided with to brake bar 2, it is spacing by this in the case where that need not brake
Device prevents maloperation, causes unnecessary loss；Meanwhile in case of emergency, directly increasing applied brake force can dash forward
The limitation of broken limiting device, implements to brake to braking device.
In conclusion the foregoing is merely a prefered embodiment of the invention, it is not intended to limit the scope of the present invention.
Within the spirit and principles of the invention, any modification, equivalent replacement, improvement and so on, should be included in the present invention's
Within protection domain.
