Shown in Fig. 2,6-10, when being parked in risk altitude to the anti-car of the utility model, the principle of work of the elevator 100 that gate is opened and process are described.
First referring to Fig. 2, when elevator normally runs, after car 120 stops, car sill 121 should with landing sill 111 level attitude at the same time, to ensure the safety turnover of personnel in sedan-chair.
When car 120 is parked in risk altitude because of certain reason, there is following several situation:
First referring to shown in Fig. 6, when car sill 121 is less than the usable height h1 of toeguard 122 apart from the height of landing sill 111, door head stop part 114 and gate stop part 124 do not interlock on the horizontally openable direction of gate 123, namely, door head stop part 114 can not stop gate stop part 124, gate 123 may be opened by passenger in sedan-chair, layer door 110 can be opened further and form the first opening M, but the space now between car sill 121 and landing sill 111 is closed by toeguard 122, therefore the second opening N can not be formed between landing sill 111 and toeguard 122, even if passenger jumps off from the first opening M, also can not there is passenger to fall the contingency of hoistway.
Below referring to shown in Fig. 7, when car sill 121 just equals the usable height h1 of toeguard 122 apart from the height of landing sill 111, door head stop part 114 just can be conflicted the top of gate stop part 124, namely, during H1=h1+h2+h3, this is the first critical conditions, under this state, the top of gate stop part 124 is stopped by door head stop part 114, and then gate 123 can not be opened by passenger in sedan-chair, simultaneously, space between car sill 121 and landing sill 111 is just closed by toeguard 122, therefore, the first opening M and the second opening N can not be formed, there is not passenger to fall the danger of hoistway.
Then referring to Fig. 8, when car sill 121 is greater than the usable height h1 of toeguard 122 apart from the height of landing sill 111 and is less than layer door head trim 112 apart from the height H 2 of landing sill 111, the second opening N is formed between toeguard 122 and landing sill 111, but because door head stop part 114 pairs of gate stop parts 124 stop, gate 123 can not be opened by passenger in sedan-chair, therefore the first opening M there will not be, and in sedan-chair, passenger can not fall hoistway.
Referring again to Fig. 9, when the lower edge of car sill 121 and layer door head trim 112 is in same level position, door head stop part 114 just can stop gate stop part 124 bottom, that is, during h2=H1-H2, this is the second critical conditions, under this state, gate stop part 124 is stopped by door head stop part 114 and gate 123 can not be opened by passenger in sedan-chair, and therefore the first opening M there will not be, although be formed with the second opening N, in sedan-chair, passenger can not fall hoistway.
When car 120 continues to raise on basis shown in Fig. 9, make car sill 121 higher than after layer door head trim 112, the second opening N can be formed, and gate stop part 124 departs from the stop of door head stop part 114, gate 123 may be opened by passenger in sedan-chair, but now faced by car 120 is well enclosure or last layer landing sill 111, there is not passenger in sedan-chair yet and crash into the risk of hoistway successively along the first opening M, the second opening N.
In summary, when above-mentioned car 120 is parked in risk altitude, the technical solution of the utility model occurs when the first opening M, the second opening N can be made different, thus can prevent gate 123 from being pushed aside voluntarily by passenger in sedan-chair, and then passenger in generation sedan-chair can be avoided to crash into the safety misadventure of hoistway.And in these cases, by professional, car 120 is moved to safe parking height and rescue.
