When simultaneous buffering again.
As a preference of the present invention, the secondary seal boss fills in the transit joint lower communication hole depth more than institute
It states primary seal boss and fills in communicating passage lower part bore depth.
As a result, the hydraulic buffer cylinder contact to earth retraction buffering when hydraulic oil be depressed into the transit joint, the rubber stopper
The secondary seal projection section hydraulic oil thrust is subject to be pushed out the intercommunicating pore, when the secondary seal boss is completely de-
Communicating passage lower part endoporus is completely disengaged from primary seal boss described in the intercommunicating pore, i.e., described rubber stopper is completely de-
Fall, the gas in the buffering pneumatic cushion just can enter in the safety air cushion.
As a preference of the present invention, when the hydraulic buffer cylinder stroke is compressed into 80% ~ 95%, gas in the safety air cushion
Body is full of.
As a result, the hydraulic buffer cylinder stroke on earth when the safety air cushion fill with gas, so as to fully protect
Protect the personnel in car.
As a preference of the present invention, covered with protective pad, the protective pad on the safety air cushion of the cage bottom
For soft material.
It will not directly be trampled on the safety air cushion when people walks in the car as a result, the safety will not be made
Air cushion friction and it is damaged.
As a preference of the present invention, fitting is installed on the car bottom surface, two sides during the safety air cushion unaerated
And medial surface, and side setting height(from bottom) is more than 1m.
In conclusion the invention has the advantages that：
The elevator with buffer unit of the present invention sets safety air cushion in car, and hydraulic buffer cylinder and buffering are set outside car
Trigger safety air cushion work while air cushion, hydraulic buffer cylinder and buffering pneumatic cushion work, it can not only be when used during elevator falling bottoms out
Play the role of buffering, while the personnel in car are subject to safety air cushion protection from shocking damage, coordinating protection inside and outside car
Effect is more preferable.

Specific embodiment
Below in conjunction with attached drawing, by specific embodiment, the invention will be further described.
As shown in Figure 1, Figure 2, including car 1, substitute is equipped in car 1 for Fig. 3, Fig. 4, a kind of elevator with buffer unit
Pad 2, safety air cushion 2 are located at below the bottom surface and side of car 1；
1 outside lower section of car is equipped with hydraulic buffer cylinder 3 and buffering pneumatic cushion 4, and hydraulic buffer cylinder 3 is vertically arranged at 1 bottom of car
Edge, buffering pneumatic cushion 4 are arranged at 1 bottom centre of car；
Communicating passage 5 is provided between safety air cushion 2 and buffering pneumatic cushion 4, is equipped with transit joint 51 in communicating passage 5, transition connects
First 51 lower end is equipped with intercommunicating pore 511, and side is equipped with the interface connected with intercommunicating pore 511；
Hydraulic buffer cylinder 3 is connected one end with car 1 equipped with oil pipe 31, and oil pipe 31 is connected to 51 side face port of transit joint；
5 lower end of communicating passage is equipped with rubber stopper 52, and rubber stopper 52 includes primary seal boss 521 and secondary seal boss 522,
Primary seal boss 521 fills in 5 lower part endoporus of communicating passage, and secondary seal boss 522 fills in 51 lower communication hole of transit joint
511。
As shown in Figure 1, Figure 2, hydraulic buffer cylinder 3 is multi-stage oil cylinder, and fully extended state is in when elevator works normally, and internal
Full of hydraulic oil.
As shown in Figure 1, Figure 2,3 stroke length of hydraulic buffer cylinder is more than 1.5m.
3 trip segment of hydraulic buffer cylinder is used for car into row buffering, and the longer effect of length is better, in order to ensure buffering effect
Stroke length need to be more than 1.5m.
Such as Fig. 1, buffering pneumatic cushion 4 when elevator works normally inside gassy, and bottommost height is than hydraulic buffer cylinder 3
High 0.3 ~ the 0.5m in bottom when fully extended.
Hydraulic buffer cylinder 3 first contacts to earth buffering as a result, be retracted to stretch out it is same again when bottom surface is flushed with 4 bottommost of buffering pneumatic cushion
When buffer.
Such as Fig. 4, secondary seal boss 522 fills in 51 lower communication hole of transit joint, 511 depth more than primary seal boss
521 fill in 5 lower part bore depth of communicating passage.
As a result, hydraulic buffer cylinder 3 contact to earth retraction buffering when hydraulic oil be depressed into transit joint 51, the two level of rubber stopper 52 is close
522 part of envelope boss is subject to hydraulic oil thrust to be pushed out intercommunicating pore 511, when secondary seal boss 522 completely disengages intercommunicating pore 511
Primary seal boss 521 has completely disengaged 5 lower part endoporus of communicating passage, i.e. rubber stopper 52 is completely fallen off, in buffering pneumatic cushion 4
Gas just can enter in safety air cushion 2.
When 3 stroke of hydraulic buffer cylinder is compressed into 80% ~ 95%, gas is full of in safety air cushion 2.
As a result, 3 stroke of hydraulic buffer cylinder on earth when safety air cushion 2 fill with gas, so as to the car that adequately protects
Interior personnel.
As shown in Figure 1, Figure 2, covered with protective pad 6 on the safety air cushion 2 of 1 bottom of car, protective pad 6 is soft material.
People will not be directly trampled on safety air cushion 2 during walking in the car 1 as a result, will not make safety air cushion 2 rub and
It is damaged.
As shown in Figure 1, Figure 2, fitting is installed on 1 bottom surface of car, two sides and medial surface, and side during 2 unaerated of safety air cushion
Face setting height(from bottom) is more than 1m.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the design of the present invention
It is defined with scope.On the premise of design concept of the present invention is not departed from, ordinary people in the field is to the technical side of the present invention
The all variations and modifications that case is made, should all drop into protection scope of the present invention, the claimed technology contents of the present invention,
Through all recording in detail in the claims.
