Concrete action specification for elevator different conditions Xiamen cutter is as follows:
The action specification of lift car in onlocking zone is as follows:
A. during door machine normal door: the outwards movement of door machine link plate, the roating sphere 11 that door cutter is griffed on plate 9 scrolls up along guide rail, drives to griffe plate 9 and rotate, and by transmission arm 7, pipe link 6 is moved up, thus allows a cutter blade return sword.When door cutter blade touches Room croquet, the barrier force of Room croquet can pass to transmission arm thus allow bearing pin 14 move downward, simultaneously by Room door-lock opening along waist hole 9-1.When bearing pin 14 move to waist hole 9-1 bottom after, unlocking board 12 rotates relative to griffing plate 9, and the arc section of lock crook plate 10 presses down by the solution lock ball 13 on it, and contact 17 and 19 disconnects, master lock hook 15 unlocks with auxiliary hook device and interlocking hook 21, realizes the unblock of normal switch door.
B. door machine is normal at closing time: when door machine moves to by door-closing in-place, the roating sphere 11 griffed on plate 9 is rolled downwards along guide rail, drives to griffe plate 9 and rotate, and by transmission arm 7, pipe link 6 is moved down, a cutter blade is outwards opened.After door cutter blade departs from Room croquet, the barrier force of croquet disappears, the pulling force of spring 22 and the deadweight of lock crook plate 10 are by the pressure of arc section to solution lock ball 13, bearing pin 14 is shifted onto the top of waist hole 9-1, master lock hook 15 latches downwards simultaneously, keep the locking with auxiliary hook device and interlocking hook 21, contact switch 17 and 19 closes, and car door lock closes.In addition because Room croquet relieves the contact with door cutter, Room door lock is also by automatic blocking.
C. outside the Room, car door lock unlocks: in the Room, external application triangular key opens Room door lock, firmly open Room door, Room croquet touches the left blade of a cutter 3 and pushes the outwards movement of left blade 3, pipe link 6 is driven to move downward by left-hand rotation swing arm 5, transmission arm 7 hauls bearing pin 14 and moves downward along waist hole, unlocking board 12 is allowed to rotate relative to griffing plate 9, by separating lock ball 13 by the arc section of lock crook plate 10 to pressing down, thus allow master lock hook 15 unlock with auxiliary hook device and mutual hook plate 21, contact 17 and 19 disconnects, and realizes the unblock of car door lock.No matter motion that is charged at door machine or uncharged situation Xiamen cutter is all same principle to this situation.
D. in car, car door lock unlocks: in sedan-chair, firmly push gate aside, the outwards movement of door machine link plate, all motion principle of back door cutter and door machine normal door time just the same.In addition, no matter whether door machine is charged, and when pushing gate in sedan-chair aside, the motion principle of door cutter is also all the same.
When above c and d, as long as close the door confining force within the specific limits when design gate machine, the power of pushing Room gate in any case from the Room or in sedan-chair aside that just can meet new national standard requirement is not more than 300N.
The action specification of lift car in non-onlocking zone is as follows:
E. door machine normal door: door machine link plate outwards movement, the roating sphere 11 that door cutter is griffed on plate 9 scrolls up along guide rail, drives to griffe plate 9 and rotate, and by transmission arm 7, pipe link 6 is moved up, thus allows a cutter blade return sword.Owing to not having the stop of Room croquet, bearing pin 14 is in the top of waist hole 9-1 always, and unlocking board 12 does not rotate relative to griffing plate 9, and separate lock ball 13 and roll along the arc section of lock crook plate 10 always, lock crook plate 10 also can not rotate.Contact switch socket 19 keeps with the closed of contact pin 17 and along parallel motion together with the moving parts on auxiliary hook device 18, until master lock hook and auxiliary hook device or interlocking hook hook.Now gate open gap is less than 50mm, and car door lock cannot unlock.
F. door machine is normally closed the door: open the door contrary with door machine, and roating sphere 11 is rolled downwards, drives to griffe plate 9 and rotate round about, thus allows a cutter blade open.Because do not have Room croquet, the same with normal door, car door lock is in locking states always.If door machine is closed the door from other positions, when by door-closing in-place, the tilting section along auxiliary hook device or interlocking hook 21 upper end moves by master lock hook 15, automatically latches, keep the locking state of car door lock under being then with the effect of lock crook plate 10 and spring 22.And then realize normally closing the door of door machine.
G. push gate aside in car: push gate in car aside and make a machine link plate outwards movement, all motion principle of back door cutter and door machine normal door time just the same, realize gate and open the requirement being less than 50mm.The same with in flat bed state, no matter whether door machine is charged, and the motion principle of door cutter is the same.
H. from the Room, open gate put people's rescue: elevator is moved to the position being applicable to passenger being released car, layer door is opened by triangular key, by pulling the unblock steel rope 16 being fixed on the gate back side, the other end unlocking steel rope is fixed on lock crook plate 10, pull and unlock steel rope 16 rotation lock hook plate 10, thus allow master lock hook 15 unlock with auxiliary hook device and interlocking hook 21, realize the unblock of car door lock.Unclamp and unlock after steel rope, lock crook plate 10 reassures car door lock locking state under the effect of deadweight and spring 22.
